Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a reciprocating motion platform for oscillating a subject in a back and forth, headward to footward manner in order to externally add pulses to the fluid channels of the subject. The external addition of pulses caused by the periodic acceleration of the subject results in many therapeutic benefits.

2. Description of the Related Art

This application builds on the work previously done in this field by Non-Invasive Monitoring Systems, Inc., located at 1666 Kennedy Causeway, Suite 400 in North Bay Village, Fla., as exemplified in U.S. Pat. No. 6,155,976 to Sackner et al. entitled “Reciprocating Movement Platform For Shifting Subject To and Fro in Headwards-Footwards Direction” (hereinafter referred to as the '976 patent), U.S. patent application Ser. No. 09/967,422 (U.S. Patent Application Publication Serial No. 2002/0103454) filed by Dr. Marvin Sackner and D. Michael Inman, entitled “External Addition of Pulses To Fluid Channels Of Body To Release Or Suppress Endothelial Mediators And To Determine Effectiveness Of Such Intervention” (hereinafter referred to as the '454 publication), and U.S. patent application Ser. No. 10/439,957 (U.S. Patent Application Publication Serial No. 2003/0236476), filed by Dr. Marvin Sackner and D. Michael Inman, entitled “Reciprocating Movement Platform For The External Addition of Pulses of The Fluid Channels of a Subject”, (hereinafter referred to as the '957 application). All of the '976 patent, the '454 publication, and '957 application are hereby incorporated by reference.

Both the '976 patent and the '957 application describe reciprocating movement platforms which can be used in medical treatments based on the external addition of pulses, as well as various medical treatments based on the external addition of pulses. The '454 publication is directly mostly to medical treatments. Although the present application builds on these three works, it is not limited by them.

Although the three works are incorporated by reference, a description of one embodiment of a reciprocating movement platform in the '957 application is presented below to provide a background by which to understand the present invention. The placement of this description in the background section does not mean to suggest by any means that the applicant considers or admits that the '957 application is necessarily prior art to the present application. Its placement here is merely to demarcate the material disclosed in the '957 application from the new material described herein.

The '957 application described one embodiment of a reciprocating movement platform as shown in FIGS. 1, 4 , 5 , and 6 . FIGS. 1, 4 , 5 , and 6 show a completely constructed reciprocating movement platform comprised of a mattress 101 for the subject to lie upon, a pillow 102 for the subject's head, a footboard frame 103 with cast shoes 104 attached in order to secure the subject, a mattress support 105 to hold the mattress 101 and to which the footboard frame 103 is attached, a box frame 800 which holds the drive machinery (or “drive”) 200 onto which the mattress support 105 is attached, bumpers 820 attached to the top and bottom of the box frame 800 , and casters 830 at the four corners of the bottom of the box frame 800 for moving the reciprocating movement platform.

The entire reciprocating movement platform system (without patient, i.e., mattress 101 and mattress support 105 , footboard support 105 , box frame 800 , and drive machinery 200 ) weighs between 400 and 500 lbs. The entire reciprocating movement platform system is 30″ wide, which is the standard width of a hospital gurney, so that it may be easily moved through doorways, semi-crowded offices, etc. The length of the entire system from bumper to bumper is 88″, which is as long as a standard twin or king size bed. The mattress 101 is 30″ above the floor, and the top of the footboard support 103 is 42″ above the floor.

The mattress support 105 secures the mattress 101 by means of Velcro strips. The mattress support 105 and footboard support 105 together weigh roughly 120 lbs. total. When assembled, the combined mattress support 105 and footboard support 105 are 30″ wide and 82″ long. The mattress 101 is 6″ thick, 30″ wide, 80″ long, and weighs approximately 30 lbs. The top 3″ of the mattress foam is the “visco-elastic” type foam for form-fitting comfort while the subject is on the platform. The mattress 101 can be designed to fold in half for easier transport and storage.

FIG. 7 shows the cast shoes 104 and the footboard frame 103 to which they are attached. The cast shoes 104 of the footboard frame 103 are the only means by which the subject is secured to the mattress support 105 , and thus, is the means by which the subject is “pulsed” by the reciprocating platform. The two cast shoes 104 are rigidly attached by nuts and bolts to the footboard frame 103 . Once the subject is lying on the mattress 101 , he or she will put his or her feet (with shoes on) into the cast shoes 104 and then the cast shoes 104 will be secured around the shoes by a system of Velcro and straps and cloth. Experiments have shown that “one size fits many”, with the cast shoes 104 servicing most adults quite adequately due to the flexibility of the Velcro closure system. The feet may be fastened in the cast shoes 104 by other means, such as a ski boot-like apparatus, or another fastening means, such as a snap, a buckle, a lock, etc. connection.

The casters 830 on the bottom portion of the reciprocating movement platform are 6″ hospital bed casters with central locking features; these provide easy rolling and maneuvering, good ground clearance, easy locking (as shown by the brake petal), and an attractive appearance. The ground clearance is approximately 8″, which accommodates the use of equipment (such as hoists) to lift the reciprocating movement platform. The bumpers 820 make sure the reciprocating platform is not set too close to a wall by extending further out than the mattress support 105 . The mattress support 105 is 82″ long and, when the platform is engaged in a reciprocating movement, has a range of movement of +/−2″. The bumpers 820 are built to extend 1″ beyond the furthest limit the mattress support 105 can travel so that the reciprocating movement platform will not be accidentally set too close to a wall where it might bump the wall during operation.

The drive machinery (or “drive”) 200 is enclosed within the box frame 800 and, as such, cannot be seen from the outside of the fully assembled movement platform. Supported by the box frame 800 and attached to the mattress support 105 , the drive 200 provides the reciprocating movement of the device. The reciprocating (headwards-footwards) movement preferably has a rate of about 120-180 rpm with a force in the range of about +/−0.2 to about +/−0.3 g. The relationship between the parts can be seen in the exploded view of the reciprocating movement platform shown in FIG. 1. Starting from the top, the mattress 101 attaches to the mattress support 105 with Velcro strips, while the footboard frame 103 (with attached cast shoes 104 ) is bolted onto the mattress support 105 . The mattress support 105 is securely attached to the drive 200 . The drive 200 has four track wheels 232 located in the four top corners of the drive 200 . These wheels 232 sit in four similarly placed tracks in the box frame 800 . Hence, the drive 200 , mattress support 105 , and mattress 101 form one part of the assembled movement platform, and the only physical connection between this top part and the bottom box frame 800 is the four wheels 232 of the drive 200 sitting in the four tracks of the box frame 800 .

When the drive 200 , by means which will be discussed further below, moves within the box frame 800 , the wheels 232 move within the tracks, which serve to both support the drive 200 and limit the reciprocating motion of the drive 200 . The track 810 on top of the box frame 800 has rounded ends so that the wheel 232 of the drive 200 may only move a certain distance in either direction. The track is beveled so that the track wheel 232 of the drive 200 will rest naturally in the center of the track. The track is also located near the metal support struts of the box frame 800 which thus transfer the weight of the drive 200 (and the attached mattress support 105 , mattress 101 , and subject) directly down to the caster 830 in the corner below.

The box frame 800 weighs about 120 lbs. and serves at least the following five purposes: 1) supporting the rest of the platform (the drive 200 , mattress support 105 , mattress 101 , and subject); 2) providing a foundation that can be moved or anchored by means of the casters 830 ; 3) maintaining an adequate distance from surrounding walls by means of its bumpers 820 ; (4) carrying the system electronics; and (5) encasing the drive 200 for safety and noise reduction. In addition, the box frame 800 provides ground clearance for the hoist legs.

The drive 200 weighs 200 lbs and is 24″ wide. The displacement modules in the drive 200 take the form of two pairs of rotating counterweights, connecting belts, pulleys, springs, and motors. FIGS. 2A and 2B are drawings of a side view and a top view, respectively, of the drive 200 and its various mechanisms. In FIGS. 2A and 2B, the two pairs of drive weights 215 A & 215 B and 225 A & 225 B are shown attached to their respective horizontal shafts 210 and 220 . These shafts are attached by means of struts to the frame of the drive 200 . The four track wheels 232 can be seen in FIGS. 2A-2B. There are two motors, the drive rotation motor 1700 which drives the drive weights and a linear displacement motor 260 which sets the phase difference between the two pairs of drive weights. The drive rotation motor 1700 is a 180VDC ½ hp 0-1750 RPM motor, although only 1/10 hp is actually used. The linear displacement motor 260 is a 9″ per minute 400 lb. 110VAC linear displacer with 12″ of travel.

The movement of counterweights 215 A and 215 B as seen from above is shown in FIGS. 3A-E. In FIG. 3A, the centers of gravity of both drive weights 215 A and 215 B are on the same line 401 from center drive shaft 210 . As center drive shaft 210 continues to rotate in FIG. 3B, drive weights 215 A and 215 B continue their rotations in opposite directions: drive weight 215 A in a clockwise direction, drive weight 215 B in a counter-clockwise direction. In FIG. 3C, the drive weights have moved into positions opposite each other. This is beneficial because the force of the two drive weights are also in opposite directions and thus, negate each other's effect. The rotation continues in FIG. 3D and then the drive weights end up adding the force of their weights in the same direction in FIG. 3E. FIGS. 3A-E show how the motion of the drive weights moves the drive 200 up and down the box frame tracks (i.e., headwards and footwards for a subject on the mattress 101 ), but not sideways within the box frame 800 . If FIG. 3A is the position which causes the headward movement, FIG. 3C is the position which negates any movement, and FIG. 3E causes the footward movement.

As can be seen in FIGS. 2A-2B and 3 A- 3 E, the drive weights are of unequal size. This is because the weights are located at different distances from the center of drive shaft 210 . If the drive weights were the same mass, their effects would not be balanced and the drive 200 would rock sideways in the box frame 800 . However, if drive weight 215 B is a predetermined amount of mass less than drive weight 215 A, the effect of the drive weights when rotating in opposite directions will cancel each other out. Because of this arrangement, the drive weights are in the same horizontal plane as shown in FIG. 2, which greatly reduces any shimmy effect that was produced in previous platform versions which had their drive weights in different horizontal planes. The outer edge of drive weight 215 A is 12″ from drive shaft 210 and this outer edge travels past the very outside edge of the drive itself when rotating.

FIG. 2B shows the pulley system with drive belt 370 and the phase control belt 380 . The drive belt 370 runs from drive rotation motor 1700 to drive shaft 210 and provides the power to rotate drive weights 215 A and 215 B around drive shaft 210 and indirectly provides the power to rotate drive weights 225 A and 225 B around shaft 220 . Drive belt 370 is a ¾″ L pitch timing belt, although a timing belt is not required in this position. Because of the size of the wheel around drive shaft 210 which is driven by drive belt 370 in comparison to the size of rotation shaft, there is a 5:1 speed reduction from the drive rotation motor 1700 to the actual rotational speed of the drive weights.

Phase control belt 380 runs around four pulley wheels of equal size: a release pulley wheel, a drive shaft pulley wheel, secondary shaft pulley wheel, and a linear displacement pulley wheel. Because it is also attached to drive shaft 210 , the drive pulley wheel drives the phase control belt. Secondary shaft pulley wheel receives the power to rotate the drive weights around shaft 220 from the drive shaft pulley wheel through phase control belt 380 . The release pulley wheel provides required tension for phase control belt 380 , and can also be used to release the tension on phase control belt 380 in order that phase control belt 380 can be taken off for repair or transport. Linear displacement pulley wheel can be moved in position up and down linear shaft under the control of linear displacement motor 260 . It is by this means that the relative phases of the two pairs of drive weights are controlled.

The drive weights around each shaft make the same movements as shown in FIGS. 3A-3E. However, one pair of drive weights can be moved in and out of phase with the other pair of drive weights. The two pairs of drive weights are in phase when they are in the same rotational positions at the same time. Both pairs would look like FIG. 3A at the same time, like FIG. 3B at the same time, etc. The two pairs are out of phase when they are not in the same rotational positions at the same time. For instance, drive weights 215 A & 215 B might be in the position shown in FIG. 3A, while drive weights 225 A & 225 B might be in the positions shown in FIG. 3B. In that case, they would be 45° out of phase with each other. Although the sideways forces of these out-of-phase pairs of drive weights would still cancel themselves out (and thus not produce a rocking effect in the movement platform), the force produced in the headwards-footwards directions would lessen in comparison to when the pairs of drive weights are in phase.

The relative phases of the pairs of drive weights are controlled by the linear displacement motor 360 , which controls the pulley system. The speed of rotation of the pairs of drive weights are controlled by increasing or decreasing the speed of the drive rotation motor 1700 . Thus, one can control both the speed of the headwards-footwards movement (by increasing or decreasing the speed of the drive rotation motor 1700 ) and the force applied by the headwards-footwards movement (by moving the pairs of drive weights in and out of phase with each other through linear displacement pulley wheel under the control of linear displacement motor 360 ). In its simplest form, the control electronics of the present invention merely control these two variables in order to get the desired effect on the subject (as described, for example, in the '962 patent, the '454 publication, and the '957 application). A handheld controller with a communication link to the control electronics of the drive 200 may be used by the health care provider or the subject him- or herself, Readings of the speed and peak acceleration could also be available. The control electronics also incorporate a “patient stop switch” which may be given to the subject to hold. The motors would stop whenever the switch was activated.

Although this reciprocating movement platform is well designed for providing a wide range of controlled motions to a subject on it, it is fairly heavy, and, as such, may not be appropriate for usage in the more. Thus, there is a need for a reciprocating movement platform with reduced weight.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

The present invention relates to both an apparatus and methods of treatment using periodic acceleration. This portion of the application is broken into two sections: section I will describe some preferred embodiments of the apparatus, and section II will describe methods of treatment.

I. The Reciprocating Movement Platform

In the current commercial model of the reciprocating movement platform, controls are available to adjust cycling speed and amplitude of platform displacement. This combination can be monitored by an accelerometer to estimate of the magnitude of applied periodic gravitational (i.e., acceleration-based) forces. This current model is capable of fine-tuning, but is also fairly heavy, and is thus appropriate for use in an institution, such as a clinic or hospital, or a doctor's office.

Using a dose response curve of nitric oxide released from periodic acceleration (obtained from analysis of the descent of the dicrotic notch of the finger pulse using a photoelectric-plethysmographic sensor), it has been determined that, with the motion platform cycling rate fixed at 140 cycles per minute, periodic acceleration values between ±0.20 and ±0.30 g produced more effective release of nitric oxide than ±0.15 or ±0.10 g. (Sackner M A, Gummels E M, Adams J A. Dose responsiveness of dicrotic notch position in periodic acceleration . Am. J. Respir. Crit. Care Med. 169[7], A178. 2004.). For adults with normal body weight, settings of approximately ±0.20 g and rate of 140 cycles per minute and for obese adults, settings of approximately ±0.17 and rate of 140 cycles per minute provide a proper balance between nitric oxide release and subject comfort during periodic acceleration treatments. However, to be more certain of such settings, it may be necessary to analyze the position of the dicrotic notch and the amplitude of cycling and the time of the cycle as a measure of nitric oxide release with the current periodic acceleration motion platform to more precisely set the appropriate parameters for the home model.

Thus, since periodic acceleration gravitational forces within a narrow range produce an effective release of nitric oxide, it was realized that a simplified reciprocating platform is possible, where the amount of machinery in the embodiments described in the '957 application can be sharply reduced, resulting in a reduction of the weight of the platform by hundreds of pounds, and thereby making a more suitable and economical home model reciprocating platform.

In one embodiment of the presently preferred invention, the amount of displacement of drive module 200 is fixed, rather than variable, as it is in the '957 application. With such a change, the complex machinery in the embodiments of the '957 application are no longer necessary. Specifically, there is no need for the two large, heavy electrical motors, or the complex system of fly wheel belt assemblies which provide both the speed and displacement adjustments in the '957 application.

The new “home unit” motion platform will provide variable speed, but fixed displacement. It will use the existing welded box frame 800 , or a bolted, wrought aluminum modular box frame (with greatly reduced weight), such as the modular elements made by Item, Solingen, Germany. A simplified motor driving system will be attached to the box frame 800 rather than being contained within drive module 200 , as it is in the '957 application. This simplified motor driving system will ‘push’ and ‘pull’ drive 200 through a sinusoidal horizontal, head to foot motion of approximately 2.5 cm or less. The stroke distance is fixed during manufacture for the desired periodic acceleration gravitational setting. The cycling speed is adjusted to a given range of speeds. The presently preferred drive for the home model device is a rotary eccentric mounted to box frame 800 , but coupled to drive 200 . It is powered by an adjustable AC drive motor, powered via a 120 VAC, single-phase input (50 or 60 Hz). The adjustable AC drive motor provides an adjustable frequency and voltage output of 0-60 Hz, 0-230 VAC, 3-phase power. An example of such a variable speed AC drive motor rated at ½ HP is manufactured by AC Tech (Model SM005S, AC Technology, Usbridge, Mass. 01569). It has an adjustable acceleration/deceleration control; the variable speed can be controlled thereby via a front panel.

The adjustable AC drive motor powers a three-phase induction, brushless motor from 0 to 1800 rpm with a totally enclosed, non-ventilated, flange (AG induction motor, 56C flange, TENV construction, 230VAC, 3 ph, 60 Hz, Baldor Electric Company, Fort Smith Ark. 72901) mounted to an industrial rated right angle worm reducer of 10:1 reduction that converts the rotary motion of the shaft of the AC motor into linear displacement. The worm reducer is provided with an output shaft, whereupon the rotary eccentric drive is fixed and keyed. The worm reducer with 56C face input is scaled for lift lubrication (Model NMRV-040-10:1-56 C, Motovario, Alpharetta, Ga. 30005). On the end of the worm reducer output shaft is a plate that can be securely bolted to another plate attached to the flat surface of one end of the frame of drive module 200 , thereby imparting a head to foot linear sinusoidal motion. It should be recognized that other models of the components of the drive and frame and manufacturers could be substituted for these “off the shelf” parts in the fabrication of the home periodic acceleration, motion platform device. Furthermore, different constructions and architectures may be used, as would be known to one skilled in the art, for having a motor attached to box frame 800 which imparts the head to foot motion of drive module 200 .

Treatments with periodic acceleration are self-limited for acute soft tissue and bone injuries. They serve as a jump-start for patients in whom aerobic exercise is one of the recommended first line treatments such as coronary artery disease, peripheral vascular disease, fibromyalgia and chronic fatigue syndrome. However, treatment is lifetime for most chronic inflammatory diseases that encompass 1) neurological diseases such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis, neuropathy, etc., 2) rheumatological diseases such as osteoarthritis, rheumatoid arthritis, etc., 3) gastrointestinal diseases such as Crohn's disease, ulcerative colitis, etc., 4) liver diseases such as hepatitis C and portal cirrhosis, 5) kidney diseases such as glomerulonephritis, etc. 6) urinary tract diseases such as interstitial cystitis, etc. Therefore, a cheaper, simplified, periodic acceleration device of less weight than the current design is needed for home applications. Further, the external appearance may take several forms depending upon use and consumer preferences, viz., a stand alone medical device, to also serve as a single or queen size bed for sleeping, or to be incorporated into a sofa design and also serve for sitting. The dimensions of the frame can be increased in width to accommodate two individuals or side-to-side periodic acceleration.

The use of the digital pulse wave and R wave trigger recording from the electrocardiograph during varied settings of periodic acceleration amplitude and rate in cycles per minute allows analysis of the descent of the dicrotic notch as described in the '957 application. The magnitude of descent of the dicrotic notch and/or the cycle length and magnitude of the rise and fall of the dicrotic notch during periodic acceleration provides an estimate of the effectiveness of nitric oxide released from activation of endothelial nitric oxide synthase by pulsatile shear stress. This enables transfer of optimal settings from the current device to the home device that allows control of rate with a fixed setting for amplitude adjusted in the factory where the home device is manufactured.

Although use of the preferred embodiment of the reciprocating movement platform is preferred and the descriptions below are based on its use, another type of device which could apply pulses in the manner appropriate for the particular treatment (as discussed below) may be used.

      A. Treatment of Cancer

Tumors in which nuclear factor kappa beta is present in the nucleus of cells (constitutive activation) include the following among others (Garg A, Agawam B. Nuclear transcription factor - kappa B as a target for cancer drug development . Leukemia 2002; 16:1053-68); Bus-Ramos C E, Roche F C, Shishodia S, Medeiros L J, Kantarjian H M, Vadhan-Raj S, Estrov Z, Smith T L, Nguyen M H Aggarwal B B. Expression of constitutively active nuclear - kappa B RelA transcription factor in blasts of acute myeloid leukemia . Hum Pathol 2004; 35: 246-253):

    • B cell lymphoma
    • Hodgkin's disease
    • T cell lymphoma
    • adult T cell lymphoma
    • acute lymphoblastic leukemia
    • mantle cell lymphoma
    • myeloid leukemias
    • gastric cancer
    • breast cancer
    • liver cancer
    • thyroid cancer
    • cervical cancer
    • pancreatic cancer
    • prostate cancer
    • mesothelioma
    • melanoma
    • head and neck squamous cell carcinoma
    • colorectal cancer
    • multiple myeloma
    • ovarian cancer
    • bladder cancer
    • lung cancer
    • vulvar cancer
    • brain tumors
    • fibrosarcoma
    • osteosarcoma
    • neuroblastoma

Tumorigenesis is characterized by self-sufficiency in growth signals, insensitivity to growth inhibition, evasion of apoptosis, immortalization, sustained angiogenesis, tissue invasion and metastasis. (Hanahan D, Weinberg R A. The hallmarks of cancer , Cell. 2000;100:57-70). Nuclear factor kappa beta that is constitutively activated in tumor cells promotes tumorigenesis since this gene produces negative feedback of nuclear factor kappa beta, causes cancer cell proliferation, prevents apoptosis (programmed cell death), increases angiogenesis, and increases metastatic potential. (Garg A, Aggarwal B B. Nuclear transcription factor - kappa B as a target for cancer drug development . Leukemia 2002:16:1053-68; Bharti A C, Aggarwal B B. Nuclear factor - kappa B and cancer: its role in prevention and therapy . Biochem. Pharmacol 2002; 64:883-88). Because of these factors, Karin suggested that nuclear factor kappa beta should receive as much attention from cancer researchers as it has already from immunologists (Karin M, Cao Y, Greten F R, Li Z W. NF - kappaB in cancer: from innocent bystander to major culprit , Nat. Rev. Cance. 2002; 2:301-10).

Indeed, pharmacological agents that block nuclear factor kappa beta activity have been employed to treat cancerous cell lines with success (Fujioka S, Sclabas G M, Schmidt C, Niu J, Frederick W A, Dong Q G et al. Inhibition of constitutive NF - kappa B activity by I kappa B alpha M suppresses tumorigenesis , Oncogene 2003; 22:1365-70; Liptay S, Weber C K, Ludwig L, Wagner M, Adler G, Schmid R M. Mitogenic and antiapoptotic role of constitutive NF - kappaB/Rel activity in pancreatic cancer . Int. J. Cancer 2003; 735-46; Umezawa K, Ariga A, Matsumoto N. Naturally occurring and synthetic inhibitors of NF - kappaB functions , Anticancer Drug Des 2003; 15:239-44).

Although activation of nuclear factor kappa beta in cancer cells plays a major role in tumorigenesis, other factors as well contribute including overexpression of 1) vascular endothelial growth factor (VEGF), 2) interleukin 8 (IL-8), 3) large quantities of nitric oxide from inducible nitric oxide synthase (iNOS) activity, 4) mutated p53, 5) epidermal growth factor receptor (EGFR), 6) tumor necrosis factor superfamily, and 7) COX2. Vascular endothelial growth factor (VEGF) and interleukin-8 (IL-8) expressed by tumors promote angiogenesis thereby providing a blood supply to fuel tumor growth. VEGF induces proliferation of endothelial cells, increases vascular permeability, and induces activation of plasminogen activators by such cells, VEGF and IL-8 are directly expressed by tumor cells and also stimulated by nuclear factor kappa beta activation. (Xiong H Q, Abbruzzese J L, Lin E et al. NF - kappaB activity blockade impairs the angiogenic potential of human pancreatic cancer cells . Int J Cancer 2004; 108(2):181-188; Huang S, Robinson J B, Deguzman A et al. Blockade of nuclear factor - kappaB signaling inhibits angiogenesis and tumorigenicity of human ovarian cancer cells by suppressing expression of vascular endothelial growth factor and interleukin 8. Cancer Res 2000; 60(19):5334-5339).

Large quantities of nitric oxide expressed through activation of iNOS in cancer cells facilitate tumor progression. Nitric oxide produced from iNOS in at a low level in ulcerative colitis and sporadic colorectal cancer activates p53, which is anti-tumorigenic, but at a high level of production, NO may cause mutations in p53 thereby acting in a pro-tumorigenic role. Under normal circumstances, the tumor suppressor p53 is a sensor of diverse cellular stresses including DNA damage, oxidative stress, and hypoxia, and aids in directing cell cycle arrest and apoptosis (physiological programmed death of cells) through transcriptional activation of target genes like p21. p53 is the most commonly mutated gene in a broad spectrum of cancers and is often associated with tumor progression, resistance to therapy, and poor prognosis. In melanoma, p53 rarely mutates but increased expression associated with tumor progression correlates well with iNOS activity. Increased nitric oxide from activation of iNOS in melanoma cells also correlates with resistance to chemotherapeutic agents. (Goodman J E, Hofseth L J, Hussain S P et al. Nitric oxide and p 53 in cancer - prone chronic inflammation and oxyradical overload disease . Environ Mol Mutagen 2004; 44(1):3-9; Tang C H, Grimm E A. Depletion of endogenous nitric oxide enhances cisplatin - induced apoptosis in a p 53- dependent manner in melanoma cell lines . J Biol Chem 2004; 279(1):288-298.)

Epidermal growth factor receptor (EGFR) is overexpressed in tumors such as lung, colon, kidney, prostate, breast, and head and neck carcinomas, which are mostly resistant to current chemotherapies. EGF prevents apoptosis or programmed death of cancer cells like nuclear factor kappa beta, thereby rendering them immortal. Activation of the EGFR-TK enzyme also results in autophosphorylation, which drives signal transduction pathways leading to tumor growth and malignant progression. When EGFR activation is blocked with anti EGFR drugs, VGFR and IL-8 production falls. However, use of anti-EGFR agents may be associated with the side effects of skin rash and diarrhea and less frequently interstitial pneumonitis. The EGFR-TK inhibitor gefitinib (Iressa) shows clinical benefits in patients with advanced non-small cell lung cancer whose disease had previously progressed on platinum- and docetaxel-based chemotherapy regimens. (Lage A, Crombet T, Gonzalez G. Targeting epidermal growth factor receptor signaling: early results and future trends in oncology . Ann Med 2003; 35(5):327-336; Vlahovic G, Crawford J. Activation of tyrosine kinases in cancer . Oncologist 2003; 8(6):531-538.)

The tumor necrosis factor (TNF) superfamily of inflammatory cytokines mediates either proliferation, survival, or apoptosis of cells. Although distinct receptors, all members share a common cell signaling pathway that mediates the activation of nuclear factor-kappaB (NF-kappaB) and mitogen-activated protein kinases (e.g. c-jun N-terminal kinase). Under specific conditions TNF alpha is a tumor promoter and helps to produce the toxic effects associated with conventional cancer therapy, such as the cytokine release syndrome and cisplatin-induced nephrotoxicity. (Gaur U, Aggarwal B B. Regulation of proliferation, survival and apoptosis by members of the TNF superfamily . Biochem Pharmacol 2003; 66(8):1403-1408; Szlosarek P W, Balkwill F R. Tumour necrosis factor alpha: a potential target for the therapy of solid tumours . Lancet Oncol 2003; 4(9):565-573.)

Cyclooxygenase 2 (COX2) overexpression that is found most commonly in lung and colorectal cancers contributes to the tumorigenesis by at least five different mechanisms including transformation of procarcinogens on carcinogens, pro-inflammatory and immunomodulatory effect, resistance to apoptosis, angiogenesis and invasion progression. Therefore, treatment with a COX2 inhibitor in such tumors retards tumor progression. (Gasparini G, Longo R, Sarmiento R et al. Inhibitors of cyclo - oxygenase 2 : a new class of anticancer agents? Lancet Oncol 2003; 4(10):605-615).

Adhesion of circulating tumor cells to microvascular endothelium plays an important role in tumor metastasis. Tumor cells are more likely to adhere to postcapillary venules than to corresponding precapillary arterioles thereby playing an important role in tumor metastasis to distant organs. (Kong L, Dunn G D, Keefer L K et al. Nitric oxide reduces tumor cell adhesion to isolated rat postcapillary venules . Clin Exp Metastasis 1996; 14(4):335-3).

A major problem in human cancers is to distribute the pharmacological agent to the tumor without producing toxicity to normal cells. Nitric oxide released from eNOS with periodic acceleration offers a non-toxic means to suppress activated nuclear factor kappa beta (Stefano G B, Prevot V, Cadet P, Dardik I. Vascular pulsations stimulating nitric oxide release during cyclic exercise may benefit health: a molecular approach ( review ), Int. J. Mol. Med. 2001; 7:119-29). Further, since tumors are characterized by a well-developed blood supply, distribution of the nitric oxide suppressant activity on activated nuclear factor kappa beta does not pose a problem. Both aerobic exercise and periodic acceleration increase shear stress to the endothelium but there are differences between the two with respect to distribution of blood flow and NO from eNOS, particularly with regard to the viscera. Aerobic exercise causes diminution of blood flow to the internal organs whereas periodic acceleration increases blood flow to these organs, e.g., liver, gastrointestinal tract, and kidneys. (Adams J A, Mangino M J, Bassuk J et al. Regional blood flow during periodic acceleration . Crit Care Med 2001; 29(10):1983-1988.). Miyauchi et al. showed that both eNOS activity and NOx are diminished in the kidneys along with decreased blood flow with exercise while the opposite takes place with pulmonary blood flow. (Miyauchi T, Maeda S, Lemitsu M et al. Exercise causes a tissue - specific change of NO production in the kidney and lung . J Appl Physiol 2003; 94(1):60-68.)

Periodic acceleration through nitric oxide release from activation of eNOS suppresses activity of nuclear factor kappa beta. This was recently demonstrated in a sheep model of asthma, which is an example of an nuclear factor kappa beta disease. Periodic acceleration (pGz) stimulates NO release from endothelial nitric oxide synthase (eNOS) through pulsatile shear stress (Adams et al. Effects of periodic body acceleration on the in vivo vasoactive response to N - w - nitro - L - arginine and the in vitro nitric oxide production . Ann. Biomed. Engineer. 2003;31:1337). It was found that: a) pretreatment with pGz significantly blunts the early (EAR) probably through NO preventing mast cell degranulation and blocks the late (LAR) allergen-induced airway responses in allergic sheep; b) pGz-induced protection is lost if the eNOS inhibitor, L-NAME, is given 30 min before pGz treatment and c) initiating pGz 2h after antigen challenge still blocks the LAR (Abraham et al. Periodic acceleration via nitric oxide modifies antigen - induced airway responses in sheep . Am. J. Respir. Crit Care Med. 2004;169:A321). NF-kB is a transcription factor for inflammatory cytokines involved in the LAR. There are reports that eNOS generated NO suppresses NF-kB activity (Blues'., Rivet's. Inhibitory action of nitric oxide on circulating tumor necrosis factor - induced NF - kappaB activity and COX -2 transcription in the endothelium of the brain capillaries . Neuropathol. Exp. Neurol. 2001;60:893). To determine if pGz suppresses NF-kB activity thereby affecting antigen-induced airway responses, we performed bronchoalveolar lavage 6h after antigen challenge and measured free p65 levels in lavage cell nuclear extracts (an indicator of NF-kB activation) by ELISA. Peak LAR (% increase over baseline) in control, pGz-treated and L-NAME+pGz treated sheep (all n=6) were 118±2%, 21±4% and 130±4%, respectively. Levels of p65/10 6 cells were 1.9- and 1.8-fold higher in the control and L-NAME+pGz groups (both p<0.05) when compared to pGz treated animals. Therefore, pGz stimulates eNOS and increases NO throughout the body, which can block NF-kB-mediated inflammation. (Sackner, M. A., Laredo, I. T., Serebriakov, I., Adams, J. A., Bassuk, J., Abraham, W. M. Periodic acceleration modifies antigen - induced airway responses in sheep by nitric oxide ( NO )- mediated down regulation of nuclear factor kappa beta ( NF - kB ). Eur. Resp. J. 2004; 24: in press).

Nitric oxide released from eNOS with periodic acceleration acts on other tumorigenic mediators directly or indirectly through nuclear factor kappa beta. Nuclear factor kappa beta regulates the expression of vascular endothelial growth factor (VEGF) and IL-8, The decreased expression of VEGF and interleukin 8 directly correlate with decreased tumorigenicity, decreased vascularization of lesions, decreased formation of malignant ascites, and prolonged survival in several cancers, e.g., pancreatic, ovarian, etc. (Xiong H Q, Abbruzzese J L, Lin E et al. NF - kappaB activity blockade impairs the angiogenic potential of human pancreatic cancer cells . Int J Cancer 2004; 108(2):181-188; Gilmore T, Gapuzan M E, Kalaitzidis D et al. Rel/NF - kappa B/I kappa B signal transduction in the generation and treatment of human cancer . Cancer Lett 2002; 181(1):1-9.) Thus, suppression of nuclear factor kappa beta activity with NO released from eNOS with pGz indirectly suppresses tumorigenesis by downregulating VEGF and IL-8. Although its action on nuclear factor kappa beta activity is favorable as anti-tumorigenic, NO released from eNOS by periodic acceleration might be considered potentially harmful because under certain circumstances it stimulates VEGF that might help tumor spread by angiogenesis. However, there are conflicting data of NO effects on VEGF that relate to the amount of released NO which can be a positive or negative modulator of the VEGF gene under the same conditions. The VEGF-mediated angiogenesis requires NO production from activated endothelial NO synthase (eNOS). Activation of eNOS by VEGF involves several pathways including Akt/PKB, Ca(2+)/calmodulin, and protein kinase C. The NO-mediated VEGF expression can be regulated by HIF-1 and heme oxygenase 1 (HO-1) activity, and the VEGF-mediated NO production by eNOS can be also modulated by HIF-1 and HO-1 activity, depending upon the amount of produced NO. These reciprocal relations between NO and VEGF may contribute to regulated angiogenesis in normal tissues. (Kimura H, Esumi H. Reciprocal regulation between nitric oxide and vascular endothelial growth factor in angiogenesis. Acta Biochim Pol 2003; 50(1):49-59.) In 10 normal subjects who received 35 daily periodic acceleration treatments, plasma VEGF doubled from baseline measurements at the end of seven weeks but was still within the upper range of normal values and similar to the VEGF elevation experienced by endurance athletes after acute exercise. (Kraus R M, Stallings H W, III, Yeager R C et al. Circulating plasma VEGF response to exercise in sedentary and endurance-trained men. J Appl Physiol 2004; 96(4):1445-1450.) In metastatic cancers, plasma VEGF greatly exceeds normal values of VEGF, for example with metastatic lung cancers, it may be 10 times the normal value. (Kishiro I, Kato S, Fuse D et al. Clinical significance of vascular endothelial growth factor in patients with primary lung cancer. Respirology 2002; 7(2):93-98.) Thus, the periodic acceleration VEGF suppressant effect through inhibition of nuclear factor kappa beta activity is of greater importance in anti-tumorigenesis than the pro-tumorigenesis effect of VEGF in angiogenesis.

Periodic acceleration by releasing small quantities of NO from eNOS suppresses iNOS activity, which is usually pro-tumorigenic. It also scavenges reactive oxygen species (ROS) and reactive nitrogen species (RNS) that are pro-tumorigenic (Stefano G B, Goumon Y, Bilfinger T V et al. Basal nitric oxide limits immune, nervous and cardiovascular excitation: human endothelia express a mu opiate receptor . Prog Neurobiol 2000; 60(6):513-530). This action of periodic acceleration therefore may help to prevent and treat colorectal and other cancers. (Hussain S P, Amstad P, Raja K et al. Increased p 53 mutation load in noncancerous colon tissue from ulcerative colitis: a cancer - prone chronic inflammatory disease . Cancer Res 2000; 60(13):3333-3337. The tumor suppressor p53 is a sensor of diverse cellular stresses including DNA damage, oxidative stress, and hypoxia, and helps to direct cell cycle arrest and apoptosis through transcriptional activation of target genes like p21. p53 is the most commonly mutated gene in a broad spectrum of cancers and is frequently associated with tumor progression, resistance to therapy, and poor prognosis. In melanoma, p53 rarely mutates but increased expression associated with tumor progression and correlates well with iNOS activity. The reason for paradoxical activity of p53 thought to be some sort of dysregulation problem. Therefore, suppression of iNOS activity by eNOS activated with periodic acceleration promotes the normal tumor suppressor function of p53. (Tang C H, Grimm E A. Depletion of endogenous nitric oxide enhances cisplatin - induced apoptosis in a p 53 dependent manner in melanoma cell lines . J Biol Chem 2004; 279(1):288-298; Stefano G B, Goumon Y, Bilfinger T V et al. Basal nitic oxide limits immune, nervous and cardiovascular excitation: human endothelia express a mu opiate receptor . Prog Neurobiol 2000; 60(6):513-530.)

Nitric oxide from NO donor drugs transiently and reversibly inhibits epidermal growth factor receptors (EGFR) in neuroblastoma cells. (Murillo-Carretero M, Ruano M J, Matarredona E R et al. Antiproliferative effect of nitric oxide on epidermal growth factor - responsive human neuroblastoma cells . J Neurochem 2002; 83(1):119-131.). There is overexpression of epidermal growth factor receptor (EGFR) in tumors such as lung, colon, kidney breast, prostate, and, head and neck carcinomas, which are mostly resistant to current chemotherapy. Activation of the EGFR-TK enzyme results in autophosphorylation, which drives signal transduction pathways leading to tumor growth and malignant progression. EGF prevents apoptosis of cancer cells prevents apoptosis thereby immortalizing tumor cells. When EGFR activation is blocked with drugs, VGFR and IL-8 production also contribute to tumor regression. (Lage A, Crombet T, Gonzalez G. Targeting epidermal growth factor receptor signaling: early results and future trends in oncology . Ann Med 2003; 35(5):327-336; Vlahovic G, Crawford J. Activation of tyrosine kinases in cancer . Oncologist 2003; 8(6):531-538.) Repeated periodic acceleration treatments by releasing NO from nitric oxide would decrease EGFR thereby causing regression of tumor growth.

Nitric oxide from eNOS activation with periodic acceleration suppresses tumor necrosis factor superfamily indirectly through inhibition of nuclear factor kappa beta. (Zhou Z, Wang L, Song Z et al. Abrogation of nuclear factor - kappaB activation is involved in zinc inhibition of lipopolysaccharide - induced tumor necrosis factor - alpha production and liver injury . Am J Pathol 2004; 164(5):1547-1556.). Periodic acceleration through shear stress suppresses tumor necrosis factor alpha activity independently of activation of eNOS. (Chiu J J, Lee P L, Lee C I et al. Shear stress attenuates tumor necrosis factor - alpha - induced monocyte chemotactic protein -1 expressions in endothelial cells . Chin J Physiol 2002; 45(4):169-176.). Nitric oxide from eNOS activation with periodic acceleration scavenges COX1 and COX2 and also inhibits lipoxygenase. (Stefano G B, Magazine H I. Nitric Oxide Autoregulation and Its Significance. In: Stefano G B, editor, Biomedical Significance of Nitric Oxide. Warsaw-New York: Medical Science International Co., Ltd., 2003: 57-68.). Finally, NO from eNOS reduces tumor cell adhesion to blood vessels and also suppresses adhesion molecules thereby suppressing tumor metastases. (Kong L, Dunn G D, Keefer L K et al. Nitric oxide reduces tumor cell adhesion to isolated rat postcapillary venules . Clin Exp Metastasis 1996; 14(4):335-343; Stefano G B, Goumon Y, Bilfinger T V et al. Basal nitric oxide limits immune, nervous and cardiovascular excitation: human endothelia express a mu opiate receptor . Prog Neurobiol 2000; 60(6):513-530.)

The availability of nitric oxide released by activation of eNOS with periodic acceleration may be improved by vitamin and dietary supplements thereby enhancing its effects in cancer treatment as well as treatment of any condition that requires increased levels of nitric oxide from eNOS. This may be of importance where endothelial function is compromised such as in arteriosclerosis. Thus, L-ascorbic acid (vitamin C), increases nitric oxide synthase (NOS) enzyme activity via chemical stabilization of tetrahydrobiopterin (BH4). Vitamin C also increases tetrahydrobiopterin and NOS activity in blood vessels. The beneficial effect of vitamin C on vascular endothelial function appears to be mediated in part by protection of tetrahydrobiopterin and restoration of eNOS enzymatic activity. Prolonged high activity of iNOS may be detrimental to vascular function due to “uncoupling” of eNOS and subsequent formation of reactive oxygen species (ROS). (d'Uscio L V, Milstien S, Richardson D et al. Long - term vitamin C treatment increases vascular tetrahydrobiopterin levels and nitric oxide synthase activity . Circ Res 2003; 92(1):88-95.) An oral glucose challenge causes transient impairment of endothelial function, probably because of increased oxidative stress. During oxidative stress, endothelial nitric oxide (NO) synthase (eNOS) becomes uncoupled because of decreased bioavailability of tetrahydrobiopterin (BH4), an essential cofactor of eNOS. Administration of BH4, which is available commercially in some countries but not the United States, reverses downregulation of eNOS. (Ihlemann N, Rask-Madsen C, Perner A et al. Tetrahydrobiopterin restores endothelial dysfunction induced by an oral glucose challenge in healthy subjects . Am J Physiol Heart Circ Physiol 2003; 285(2):H875-H882.) Also, folic acid administration exerts direct anti-oxidative effects and contributes to restoration of impaired NO metabolism. Folate also reduces plasma homocysteine levels, enhances eNOS, and has anti-inflammatory actions. It stimulates endogenous BH4 regeneration, a cofactor necessary for NO synthesis from eNOS, inhibits intracellular superoxide generation, and thus enhances the half-life of NO. BH4 in turn enhances NO generation and augments arginine transport into the cells. Folic acid increases the concentration of omega-3 PUFAs, which also upregulates eNOS synthesis. Vitamin C augments NO synthesis from eNOS by increasing intracellular BH4 and stabilization of BH4. (Stanger O, Weger M. Interactions of homocysteine, nitric oxide, folate and radicals in the progressively damaged endothelium . Clin Chem Lab Med 2003; 41(11):1444-1454; Das U N. Folic acid says NO to vascular diseases. Nutrition 2003; 19(7-8):686-692.). In addition, there appears to be a benefit of higher folic acid consumption in reducing risks of colon and breast cancers. (Willett W C. Diet and cancer . Oncologist 2000; 5(5):393-404) Niacin in much higher doses than recommended for daily requirements elevates high density lipoprotein (HDL) and improves endothelial function by upregulating eNOS. The dose of niacin (Niaspan, KOS) is initiated at 375 mg at night and titrated to a maximal tolerated dose of 1500 mg. Patients take aspirin 30 minutes prior to niacin to minimize side effects. (Kuvin J T, Ramet M E, Patel A R et al. A novel mechanism for the beneficial vascular effects of high - density lipoprotein cholesterol: enhanced vasorelaxation and increased endothelial nitric oxide synthase expression . Am Heart J 2002; 144(1):165-172.)

Das (Das U N. Folic acid says NO to vascular diseases . Nutrition 2003; 19(7-8):686-692) recommends the following for supplementation as an aid to achieve good endothelial function: folic acid 1 to 5 mg/day, vitamin B12 1000 ug/day, vitamin B6 5 to 10 mg/day, vitamin C 100 mg/day, L-arginine 500 mg twice a day, BH4 1 to 2 mg/Kg body weight (available in some countries but not the United States), polyunsaturated fatty acids (PUFAs) (especially eicosapentaenoic acid 120 mg/day & docosahexaenoic acid 180 mg/day. Such a supplement plan may be used in conjunction with periodic acceleration to enhance its effects on eNOS. However, Das′ recommendation for the dose of L-Arginine is probably an underestimate. Oral supplementation with large amounts (6-21 g/day) of L-arginine, the precursor of endothelial-derived nitric oxide, improves endothelium-mediated vasodilation in hypercholesterolemia. Flow mediated vasodilation is improved with 6.6 g of L-Arginine administered for in the form of a nutrient bar. (Maxwell A J, Anderson B, Zapien M P et al. Endothelial dysfunction in hypercholesterolemia is reversed by a nutritional product designed to enhance nitric oxide activity . Cardiovasc Drugs Ther 2000; 14(3):309-316.) Lower doses are ineffective. High dosage niacin may be administered in the presence of endothelial dysfunction to produce further upregulation of eNOS.

Several chemopreventive phytochemicals have been shown to inhibit COX-2 and iNOS expression by blocking NF-kappa B activation. Curcumin, a yellow pigment of turmeric ( Curcuma longa L., Zingiberaceae), the green tea polyphenol epigallocatechin gallate (EGCG), and resveratrol from grapes ( Vitis vinifera , Vitaceae) strongly suppress tumor promotion because they suppress nuclear factor kappa beta. (Surh Y J, Chun K S, Cha H H et al. Molecular mechanisms underlying chemopreventive activities of anti - inflammatory phytochemicals: down - regulation of COX -2 and iNOS through suppression of NF - kappa B activation . Mutat Res 2001; 480-481:243-268.) These phytochemicals could potentiate the effect of periodic acceleration.

Both the immediate and late complications of radiation and/or chemotherapy may be ameliorated by periodic acceleration as pre-treatment, during treatment and post-treatment. Because radiation-induced vascular injury precedes the tissue damage, vascular injury is regarded as crucial in the pathogenesis of tissue damage. Radiation injury is marked by activation of adhesion molecules that promote leukocyte infiltration of normal tissue. Radiation activates nuclear factor kappa beta, which in turn activates adhesion molecules. (Quarmby, S.; Kumar, P.; Kumar, S. Radiation - induced normal tissue injury: role of adhesion molecules in leukocyte - endothelial cell interactions . Int. J. Cancer 1999;82 385-395.) Radiotherapy and chemotherapy produce numerous adverse early and late complications. Oral and gastrointestinal (GI) mucositis, a frequent complication of anticancer treatment, threatens the effectiveness of therapy because it leads to dose reductions, increases healthcare costs, and impairs patients' quality of life. (Sonis S T, Elting L S, Keefe D et al. Perspectives on cancer therapy - induced mucosal injury: pathogenesis, measurement, epidemiology, and consequences for patients . Cancer 2004; 100(9 Suppl):1995-2025.)

Thus, periodic acceleration alone or in conjunction with chemotherapeutic or x-ray or other cancer suppressing agents or technology offers a way to treat cancers. It may permit lesser doses of radiation and/or chemotherapy thereby minimizing deleterious side effects. Furthermore, application of periodic acceleration either alone or with other preventative agents can be used to prevent cancers. Treatment with periodic acceleration avoids the late effects of radiotherapy and chemotherapy on normal tissues. The late onset of necrosis and fibrosis in normal tissues can be a serious consequence of radiotherapy and chemotherapy in cancer patients. Because radiation-induced vascular injury precedes the tissue damage, vascular injury is regarded as crucial in the pathogenesis of tissue damage. Radiation injury is marked by activation of adhesion molecules that promote leukocyte infiltration of normal tissue. The stress of radiation or chemotherapy activated nuclear factor kappa beta in turn activates adhesion molecules. (Sonis S T, Elting L S, Keefe D et al. Perspectives on cancer therapy - induced mucosal injury: pathogenesis, measurement, epidemiology, and consequences for patients . Cancer 2004; 100(9 Suppl):1995-2025) Radiotherapy for abdominal and pelvic malignancies results in an increased risk of radiation enteritis. (Bismar M M, Sinicrope F A. Radiation enteritis. Curr Gastroenterol Rep 2002; 4(5):361-365.) Late effects of radiotherapy depend upon site that of radiation and may cause the following: 1) cranial radiotherapy—neurocognitive deficits, obesity, seizures and strokes, cataracts, etc. 2) chest or mantle radiotherapy—breast cancer, thyroid cancer, hypothyroidism, pulmonary fibrosis, lung cancer, cardiac fibrosis, pericarditis, etc, 3) abdominal/pelvic radiotherapy—chronic enteritis, gastrointestinal malignancy, renal failure, hemorrhagic cystitis, bladder cancer, ovarian failure, testicular failure, etc., 4) any radiation—skin cancer, melanoma, sarcoma, etc. Late effects of chemotherapy depend upon the drug and may cause the following: 1) alkylating agents (e.g., cyclophosphamide, chlorambucil, bisulfan, procarbazine, etc.)—hypogonadism, early menopause, acute myeloid leukemia, pulmonary fibrosis, bladder fibrosis, renal failure, etc., 2) cisplatin/carboplatin—hearing loss, vertigo, tinnitis, renal failure, etc., 3) methotrexate—neurocognitive deficits, 4) anthracyclines (e.g., doxorubacin, daunorubicin, etc.)—cardiomyopathy, arrhythmia, and 4) bleomycin—interstitial pneumonitis, pulmonary fibrosis, 5) corticosteroids—osteopenia, osteoporosis, avascular necrosis, 6) epepodophylloxins—acute myeloid leukemia. (Oeffinger K C, Hudson M M. Long - term complications following childhood and adolescent cancer: foundations for providing risk - based health care for survivors . CA Cancer J Clin 2004; 54(4):208-236.)

In summary, periodic acceleration has a place in management of cancer either as a stand-alone modality or complimentary to radiotherapy and chemotherapy regimens. Periodic acceleration evokes widespread release of nitric oxide throughout body—wherever there is a blood vessel, pulsatile shear stress promotes expression of nitric oxide that suppresses directly or indirectly pro-tumorigenic mediators. These include nuclear factor kappa beta, vascular endothelial growth factor, inteleukin-8, epidermal growth factor receptor, tumor necrosis superfamily, inducible nitric oxide synthase, mutated p53, COX2, and adhesion molecules. Periodic acceleration does not harm healthy cells nor produce deleterious side effects in contrast to radiotherapy and chemotherapy thereby avoiding the late fibrotic effects of radiation and chemotherapy on normal tissues. Periodic acceleration cannot cause overdose of endothelial-derived mediators. Periodic acceleration is complementary to conventional cancer therapies without adverse “drug” interactions.” Periodic acceleration is synergistic or additive in suppression of tumorigenesis to radiotherapy and chemotherapy. Periodic acceleration mitigates the early and late complications of radiotherapy and chemotherapy. Periodic acceleration may be utilized chronically as a cancer prevention measure. Vitamin supplements, antioxidants, and phytochemicals in conjunction with periodic acceleration may increase the effectiveness of NO release from eNOS, with potential for greater suppression of nuclear factor kappa beta and other inflammatory mediators in tumors.

B. Preconditioning and/or Conditioning

Stretch-induced muscle injuries or strains, muscle contusions and delayed-onset muscle soreness (DOMS) are common muscle problems in athletes. Anti-inflammatory treatment is often used for the pain and disability associated with these injuries. The most recent studies on non-steroidal anti-inflammatory drugs (NSAIDs) in sprains and contusions suggest that their use can result in a modest inhibition of the initial inflammatory response and its symptoms. This may be associated with slight negative effects later in the healing phase. Corticosteroids have generally been shown to adversely affect the healing of these acute injuries. The beneficial effect of NSAIDs on improvement of delayed-onset of muscle soreness appears to be minimal. (Almekinders L C. Anti - inflammatory treatment of muscular injuries in sport. An update of recent studies , Sports Med 1999; 28:383-88). Prolonged and strenuous exercise induces significant increases in plasma IL-1beta, IL-6 and tumor necrosis factor alpha (Brenner I K, Natale V M, Vasiliou P, Moldoveanu A I, Shek P N, Shephard R J. Impact of three different types of exercise on components of the inflammatory response , Eur. J. Appl. Physiol. Occup. Physiol. 1999; 80:452-60; Bruunsgaard H, Galbo H, Halkjaer-Kristensen J, Johansen T L, MacLean D A, Pedersen B K. Exercise - induced increase in serum interleukin -6 in humans is related to muscle damage , J. Physiol 1997; 499 (Pt 3):833-41; Pedersen B K, Ostrowski K, Rohde T, Bruunsgaard H. The cytokine response to strenuous exercise . Can. J. Physiol. Pharmacol. 1998; 76:505-11).

There is a positive correlation between elevated serum IL-6 levels and skeletal muscle damage in terms of creatine kinase elevations (Bruunsgaard H, Galbo H, Halkjaer-Kristensen J, Johansen T L, MacLean D A, Pedersen B K. Exercise - induced increase in serum interleukin -6 in humans is related to muscle damage , J. Physiol. 1997; 499 (Pt 3):833-41). In football players who require intravenous hydration for muscle cramps after training sessions, all have extremely high levels of serum nitrite, presumably released from iNOS present in macrophages and leucocytes as a result of the stress of strenuous exercise (Maddali S, Rodeo S A, Barnes R, Warren R F, Murrell G A. Postexercise increase in nitric oxide in football players with muscle cramps . Am. J. Sports Med. 1998; 26:820-24). Athletes seem to be more prone to upper respiratory viral infections probably because strenuous exercise promotes increase of IL-6, tumor necrosis factor alpha, and large quantities of nitric oxide that compromise the immune defense system. These infections usually appear after exercise discontinuation (within 3 days) particularly in those athletes practicing sports that require a long term effort and resistance (Gani F, Passalacqua G, Senna G, Mosca F M. Sport, immune system and respiratory infections , Allerg. Immunol. (Paris) 2003; 35:41-46).

Small quantities of nitric oxide released from eNOS suppress strenuous exercise induced activation of nuclear factor kappa beta thereby diminishing IL-1beta, IL-6, tumor necrosis factor and other inflammatory cytokines and adhesion molecules. In addition, small quantities of nitric oxide from eNOS suppress activity of iNOS (Stefano G B, Prevot V, Cadet P, Dardik I. Vascular pulsations stimulating nitric oxide release during cyclic exercise may benefit health: a molecular approach ( review ). Int. J. Mol. Med. 2001; 7:119-29). This is important because large amounts of nitric oxide are released after strenuous exercise in professional football players and other athletes that are associated with severe muscle cramps.

Therefore, periodic acceleration can mitigate skeletal muscular cramps during an athletic event, and help to prevent muscle strains during an event as well as delayed onset muscular soreness (DOMS) and involuntary muscle cramps and spasms immediately following the athletic event and delayed until the sleeping hours. It has been found that an additional periodic acceleration treatment administered four to eight hours after the athletic event provides even better relief than a single pretreatment in relieving nocturnal muscle cramps.

In addition to skeletal muscle damage and propensity to viral infections associated with strenuous exercise, damage to heart muscle may occur even in normal subjects. Cardiac troponin T (cTnT) and troponin I (cTnI) are highly sensitive and specific for detecting myocardial damage even in the presence of skeletal muscle injury. Ultraendurance exercise may cause myocardial damage as indicated by elevations of these biochemical cardiac-specific markers and also by echocardiography (Rifai N, Douglas P S, O'Toole M, Rimm E, Ginsburg G S. Cardiac troponin T and I, echocardiographic [correction of electrocardiographic] wall motion analyses, and ejection fractions in athletes participating in the Hawaii Ironman Triathlon , Am. J. Cardiol. 1999; 83:1085-89; Shave R E, Dawson E, Whyte G, George K, Ball D, Gaze D C et al. Evidence of exercise - induced cardiac dysfunction and elevated cTnT in separate cohorts competing in an ultra - endurance mountain marathon race Int. J. Sports Med. 2002: 23:489-94; Ohba H, Takada H, Musha H, Nagashima J, Mori N, Awaya T et al. Effects of prolonged strenuous exercise on plasma levels of atrial natriuretic peptide and brain natriuretic peptide in healthy men , Am. Heart J. 2001; 141:751-58). There are no studies reported in the literature on normal subjects with regard to less strenuous exercise but it stands to reason that in some individuals, minor damage might occur. Minimal myocardial damage could compromise athletic performance.

Activation of eNOS to release small quantities of nitric oxide preconditions the heart against the adverse effects of compromise of the blood supply to the heart that produces myocardial damage. Periodic acceleration activates eNOS through increased pulsatile shear stress and, as such, is a means to precondition the heart. Endogenous nitric oxide 1) reduces myocardial oxygen consumption and thus improves regional myocardial function for any given level of myocardial blood flow, oxygen consumption and energetics, 2) preserves contractile calcium sensitivity during myocardial ischemia, and 3) contributes to hibernation, i.e., adaptation to myocardial ischemia, by preserving regional contractile function without any effect on myocardial energetics (Heusch G, Post H, Michel M C, Kelm M, Schulz R. Endogenous nitric oxide and myocardial adaptation to ischemia . Circ. Res. 2000; 87:146-52). Since the limitation to athletic activities often is the amount of blood pumped by the heart through the body, preconditioning with periodic acceleration serves to optimize athletic performance.

Based upon animal experiments, upregulation of endothelial nitric oxide synthase activity should increase the number of mitochondria present in skeletal muscle cells. In turn, heat production is increased within these cells thereby improving sports performances. (Nisoli E, Clementi E, Paolucci C et al. Mitochondrial biogenesis in mammals: the role of endogenous nitric oxide . Science 2003; 299(5608):896-899; Brown G C. NO says YES to mitochondria. Science 2003; 299:838-839.)

Exercise-induced bronchospasm (EIB), i.e., an asthmatic episode, affects up to 35% of athletes and up to 90% of asthmatics (Kukafka D S, Lang D M, Porter S, Rogers J, Ciccolella D, Polansky M et al., Exercise - induced bronchospasm in high school athletes via a free running test: incidence and epidemiology . Chest 1998; 114:1613-22). This factor limits athletic capabilities.

Since many athletic venues do not permit effective drugs for the treatment of asthma because of they also improve performance unrelated to alleviation of asthma, pretreatment of such athletes can be accomplished with periodic acceleration to prevent exercise induced asthma. Here, the beneficial agent, nitric oxide is generated from the athlete's own body.

Physical activity protects against ischemic stroke via mechanisms related to the upregulation of endothelial nitric oxide synthase (eNOS) in the vasculature. In wild-type mice that performed voluntary training on running wheels or exercise on a treadmill apparatus for 3 weeks, respectively, ligation of the middle cerebral artery was associated with reduced cerebral infarct size and functional deficits, improved endothelium-dependent vasorelaxation, and augmented cerebral blood flow. The neuroprotective effects of physical training were completely absent in eNOS-deficient mice, indicating that the enhanced eNOS activity by physical training was the predominant mechanism by which this modality protects against cerebral injury. (Endres M, Gertz K, Lindauer U et al. Mechanisms of stroke protection by physical activity . Ann Neurol 2003; 54(5):582-590.)

In summary, periodic acceleration treatments administered prior to an athletic event minimize delayed onset of muscle soreness (DOMS) and nocturnal muscle spasms. An additional periodic acceleration treatment administered four to eight hours following cessation of the athletic event provides even further relief. Periodic acceleration administered prior to strenuous athletic events minimizes microscopic myocardial damage. Chronic treatment with periodic acceleration improves sports performance by promoting mitochondrial biogenesis. Periodic acceleration administered prior to an athletic event protects against exercise induced asthma. Since many athletic venues do not permit effective drugs for the treatment of asthma because of they also improve performance unrelated to alleviation of asthma, pretreatment of competitive athletes can be accomplished with periodic acceleration to prevent exercise induced asthma. Chronic periodic acceleration treatments should minimize damage that might occur with ischemic events such as stroke, coronary thrombosis, pulmonary embolism, etc.

C. Weight Control

An epidemic of obesity exists in the United States and other countries of the Western World. Currently, 65% of American adults are overweight and 31% are obese. Further, this prevalence parallels the 29% prevalence of hypertension with blood pressures >140/90 or taking anti-hypertensive drugs. Weight loss is critical in the effective management of obesity hypertension and the accompanying target organ damage, although recidivism rates are high. Prevention of weight gain should be the major priority for combating hypertension and its consequences in the future. (Davy K P, Hall J E. Obesity and hypertension: two epidemics or one? Am J Physiol Regul Integr Comp Physiol 2004; 286(5):R803-R813.) Depression and obesity are linked to elevated CRP suggesting a possible synergistic effect of obesity and depressive mood on chronic low-level inflammation, which may play a crucial role in the pathogenesis of atherosclerosis. (Ladwig K H, Marten-Mittag B, Lowel H et al. Influence of depressive mood on the association of CRP and obesity in 3205 middle aged healthy men . Brain Behav Immun 2003; 17(4):268-275.) Exercise and proper diet are key to weight control but numerous studies have stressed the difficulty in getting obese patients to comply.

In a one year study, it was found that nitric oxide deficient mice (eNOS knockout) were significantly heavier than normal wild-type mice over the entire observation period even though dietary intake and activity were controlled and the same. The NO deficient had lesser oxygen consumptions and fewer mitochondria in brown adipocytes than the wild type mice. The investigators concluded that eNOS regulates mitochondrial biogenesis, energy expenditure and heat production. They noted that NOS deficiency reduced energy expenditure and produced weight gain, insulin resistance, and hypertension, which are typical features of the metabolic syndrome. (Nisoli E, Clementi E, Paolucci C et al. Mitochondrial biogenesis in mammals: the role of endogenous nitric oxide . Science 2003; 299(5608):896-899.) Based upon these findings, Brown speculated that if eNOS could be upregulated, then an increase mitochondrial number in skeletal muscle would increase sport performances, reduce obesity, treat the metabolic syndrome and even reverse aging. (Brown G C. NO says YES to mitochondria . Science 2003; 299:838-839.) I have made anecdotal observations in three subjects indicating that two, 45 minute treatments daily with periodic acceleration cause significant weight reduction over weeks to months period. A metabolic chamber study in a single subject using periodic acceleration produced an excess caloric expenditure of approximately 100 calories in 24 hours compared to a control day. Long term periodic acceleration should produce an accumulative effect as a result of increased mitochondrial biogenesis. Thus, periodic acceleration ought to play a role in the management of obesity.

Cachexia, which is marked by severe weight loss, is the opposite of obesity yet it too may respond to upregulation of eNOS but by a totally different mechanism. For example, weight loss, mostly due to skeletal muscle atrophy, is a frequent and clinically relevant problem in patients with chronic obstructive pulmonary disease (COPD) as well as in patients with neoplasms. In such patients, activation of nuclear factor kappa beta and iNOS induction takes place in the skeletal muscle and contributes to the molecular pathogenesis of cachexia along with other inflammatory cytokines. (Agusti A, Morla M, Sauleda J et al. NF - kappaB activation and iNOS upregulation in skeletal muscle of patients with COPD and low body weight . Thorax 2004; 59(6):483-487) Periodic acceleration by increasing release of small amounts of nitric oxide from eNOS suppresses nuclear factor kappa beta and iNOS activities thereby ameliorating the skeletal muscle pathology. In addition, deficiency of eNOS causes less muscle oxidative capacity as well as the activities of energy metabolism enzymes in oxidative (soleus) muscle. (Momken I, Fortin D, Serrurier B et al. Endothelial nitric oxide synthase ( NOS ) deficiency affects energy metabolism pattern in murine oxidative skeletal muscle . Biochem J 2002; 368(Pt 1):341-347.) This, too, is ameliorated with upregulation of eNOS by periodic acceleration.

In summary, periodic acceleration treatments control weight, ameliorate the metabolic syndrome, improve sports performance, and improve skeletal muscle pathology associated with the cachexia of COPD and cancers.

D. Ventricular Remodeling

While current therapeutic strategies are designed to restore blood flow to the ischemic myocardium and limit infarct size, adverse left ventricular remodeling progressing to dysfunction remains a significant complication following myocardial infarction. Ventricular remodeling also takes place in conditions associated with volume overload. Ventricular remodeling consists of change from an elliptical to a spherical left ventricular volume with concomitant increase of end-systolic and end-diastolic diameters. Reverse remodeling means a reversal of ventricular shape toward a normal shape. In myocardial infarctions, the extracellular matrix (ECM) is a key component in the remodeling process through increases of collagen in the infarct area that replace necrotic myocytes to form a scar. In addition, the matrix metalloproteinases (MMP) coordinate ECM turnover through degradation of ECM components. Several laboratories have demonstrated that MMP participates in remodeling events that lead to left ventricular dilation, and inhibition or targeted deletion of specific MMPs has beneficial effects post-myocardial infarction. (Lindsey M L, Mann D L, Entman M L et al. Extracellular matrix remodeling following myocardial injury . Ann Med 2003; 35(5):316-326) Left ventricular remodeling that occurs in mitral regurgitation and other ventricular volume overload conditions are produced by overstretch of the myocardium. (Oral H, Sivasubramanian N, Dyke D B et al. Myocardial proinflammatory cytokine expression and left ventricular remodeling in patients with chronic mitral regurgitation . Circulation 2003; 107(6):831-837; Wei C C, Lucchesi P A, Tallaj J et al. Cardiac interstitial bradykinin and mast cells modulate pattern of LV remodeling in volume overload in rats . Am J Physiol Heart Circ Physiol 2003; 285(2):H784-H792; Stewart J A, Jr., Wei C C, Brower G L et al. Cardiac mast cell - and chymase - mediated matrix metalloproteinase activity and left ventricular remodeling in mitral regurgitation in the dog . J Mol Cell Cardiol 2003; 35(3):311-319.)

Several mediators regulate ventricular remodeling. Over stretch of the myocardium due to volume overload causes expression of tumor necrosis factor alpha. (Oral H, Sivasubramanian N, Dyke D B et al. Myocardial proinflammatory cytokine expression and left ventricular remodeling in patients with chronic mitral regurgitation . Circulation 2003; 107(6):831-837.) As mentioned above, MMP's activity increases during ventricular remodeling. In experimental aortocaval fistula in rats, the number of myocardial mast cells significantly increases, and there is a close association between mast cell density and MMP activity. Cromolyn, a drug that inhibits degranulation of the mast cell prevents the increase in mast cell number and MMP activity. Therefore cardiac mast cells play a major role in regulating MMP activity in ventricular remodeling. (Brower G L, Chancey A L, Thanigaraj S et al. Cause and effect relationship between myocardial mast cell number and matrix metalloproteinase activity . Am J Physiol Heart Circ Physiol 2002; 283(2):H518-H525.) Further, there is a significant interaction of mast cells and bradykinin in the cardiac interstitium that modulates the pattern of LV remodeling in the acute phase of volume overload. (Wei C C, Lucchesi P A, Tallaj J et al. Cardiac interstitial bradykinin and mast cells modulate pattern of LV remodeling in volume overload in rats . Am J Physiol Heart Circ Physiol 2003; 285(2):H784-H792.) Cardiac mast cells and chymase are important modulators of MMP activity and extracellular matrix degradation that contribute to adverse left ventricular remodeling in chronic volume overload secondary to mitral regurgitation. (Stewart J A, Jr., Wei C C, Brower G L et al. Cardiac mast cell - and chymase - mediated matrix metalloproteinase activity and left ventricular remodeling in mitral regurgitation in the dog . J Mol Cell Cardiol 2003; 35(3):311-319.)

Another mediator that promotes ventricular remodeling is caspase-3 that is activated by myocardial stunning followin
