    Bariatric wheelchairs (often referred to as extra wide wheelchairs or heavy duty wheelchairs) are strong enough to accommodate almost any user. Just like lighter manual chairs, bariatric wheelchairs are all foldable and feature armrests and swing-away footrests - but they differ quite a bit in their construction. While lightweight wheelchairs often employ materials like aluminum or titanium alloy, a bariatric wheelchair is usually fashioned from steel. Karma 8020 X Heavy Duty Wheelchair: It comes with detachable swing away footrests. The wheel chair has flip-back armrests. It comes with centre of gravity adjustment. The wheel chair has wide profile casters. Seat Size 20'' inch & 22'' inch Total Weight 17 K.G. Heavy duty wheelchairs (often referred to as extra wide wheelchairs or bariatric wheelchairs) are sturdy enough to accommodate almost any user. Just their lighter cousins, manual chairs, heavy duty models all fold and feature arm rests and swing-away footrests - but they differ quite a bit in their construction. Heavy duty wheelchairs require more strength to push by the caregiver and by the user, if the chair is self-propelled. In some cases, it may be wise for the caregiver to ask for assistance from another person in order to push the wheelchair safely. Karma 8520 Heavy Duty Wheelchair: It comes with detachable swing away footrests. The wheel chair has flip-back armrests. It comes with centre of gravity adjustment. The wheel chair has wide profile casters. Seat Size 20'' inch & 22'' inch Total Weight 17 K.G. Features: Dual, reinforced steel cross braces. Supports individuals maximum weight.

    Powerchairs are generally four-wheeled or six-wheeled and non-folding, however some folding designs exist and other designs may have some ability to partially dismantle for transit. Four general styles of powerchair drive systems exist: front, centre or rear wheel drive and all-wheel drive. Powered wheels are typically somewhat larger than the trailing/castoring wheels, while castoring wheels are typically larger than the castors on a manual chair. Centre wheel drive powerchairs have castors at both front and rear for a six-wheel layout. Angel Wheelchair Electric standing wheelchair Standing up, driving function by power. Head and signal light (controlled by joystick). Adjustable headrest. Adjustable footplate.

Power wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but also by people with cardiovascular and fatigue based condition. An powerwheelchair powers more than just chair. It gives the power to safely travel long distances on own. It empowers to navigate through home, backyard, school, workplace or local park. It gives power to do the things,want to do. It gives power. When accidents occur that leave permanent leg injuries, or as age sets in and joint pain becomes unbearable, the power chair acts as a gateway to continue living life to the fullest.

    Golden Technologies takes all the worry out of purchasing a power wheelchair. Designers blend the most technologically advanced components with superior designs to provide with the almost in quality, comfort and style. Motorized wheelchairs to enter bike lanes if a sidewalk isn't available or passable by wheelchair. Wheelchair users would be required to yield the right-of-way to bikers. The proposal also adds motorized wheelchairs to current law affecting vehicles and bicycles on the road, including the required three foot law between bikers and drivers. Supporters bill would help wheelchair users get around quickly and that areas without sidewalks are often difficult to navigate. It's the standard chair, with the main frame attaches to the front. This isn't a futuristic design as such, but a very good way of maintaining or building strength in those who are bound to a wheelchair, and may hope to walk again in their future. Personally, this bike is pretty cool. It's got a front frame similar to a chopper, with the added comfort of a chair appose to a saddle. A new module is set to transform electric powered wheelchairs into communication hubs. An powerchair is more compact and has a better turning radius than an electric scooter; making it is easier to navigate narrow doorways and tight turns. Another advantage of the powerwheelchair is that its armchair joystick does not require an upright posture like an electric scooter's handlebars. Most power wheelchairs can also be taken apart and stowed, while scooters usually can't. Powerwheelchairs are also usually less expensive than scooters. For many disabled people, the only way to move around is by using a wheelchair. Those who cannot powered wheelchairs propel themselves with their arms, which often leads to fatigue, pain, and even permanent damage to arms and shoulders. BENEFITS: Activates circulation system and improves cardio-pulmonary function. Helps prevent decubitus sores. Improves bowel regu

Oncotarget | NADH autofluorescence, a new metabolic biomarker for cancer stem cells: Id... - 0 views

  • Vitamin C was ~10 times more potent than 2-DG for the targeting of CSCs
  • Cancer stem-like cells (CSCs) are thought to be the root cause of chemotherapy-resistance and radio-resistance
  • ultimately leading to treatment failure in patients with advanced disease [1-3]. They have been directly implicated mechanistically in tumor recurrence and metastasis, resulting in poor patient survival
  • ...26 more annotations...
  • mitochondrial biogenesis may be a key driver of the CSC phenotype
  • Our results indicate that increased mitochondrial oxidative stress and high NADH levels are both key characteristics of the CSC metabolic phenotype
  • high levels of NAD(P)H auto-fluorescence are known to be a surrogate marker for mitochondrial “power”, high OXPHOS capacity and increased ATP production
  • CSCs may be strictly dependent on NAD(P)H to maintain their enhanced mitochondrial function
  • an intact NAD+ salvage pathway is strictly required for mammosphere formation, supporting our results using NAD(P)H auto-fluorescence, which enriched CSC activity by more than 5-fold.
  • Since glycolysis is especially critical for maintaining the TCA cycle, OXPHOS and overall mitochondrial function, we next assessed the effects of known glycolytic inhibitors
  • we show that two other natural products that function as effective glycolysis inhibitors, also inhibited mammosphere formation. More specifically, vitamin C (ascorbic acid), which induces oxidative stress and inhibits the activity of GAPDH (a key glycolytic enzyme) [17], also inhibited mammosphere formation, with an IC-50 of 1 mM (Figure 7B). Therefore, vitamin C was ~10 times more potent than 2-DG at targeting CSC propagation
  • silibinin (the major active constituent of silymarin, an extract of milk thistle seeds) [18], which specifically functions as an inhibitor of glucose uptake, blocked mammosphere formation, with an IC-50 between 200 and 400 µM
  • caffeic acid phenyl ester (CAPE), a key component of honey-bee propolis, has potent anti-cancer properties
  • Propolis has a strong history of medicinal use, dating back more than 2,000 years
  • Because of it aromatic ring structure (Figure 8), we speculated that CAPE might function as a potent inhibitor of oxidative mitochondrial metabolism
  • CAPE quantitatively inhibits the mitochondrial oxygen consumption rate (OCR) and, in turn, induces the onset of aerobic glycolysis (ECAR)
  • CAPE shows a clear selectivity for targeting CSCs and adherent cancer cells, relative to normal fibroblasts.
  • CAPE functions as a “natural” mitochondrial OXPHOS inhibitor, that preferentially targets the CSC sub-population. This could explain CAPE’s known anti-cancer properties
  • Our data directly shows that a small fraction of the total cell population, characterized by increased PGC1α activity, high mitochondrial ROS/H2O2 and high NADH levels, has the ability to survive and grow under anchorage-independent conditions, driving mammosphere formation
  • We highlight the utility of certain natural products, such as Silibinin, Vitamin C and CAPE, that could be used to therapeutically target CSCs. Silibinin is the major active component of silymarin, which is an extract prepared from milk thistle seeds.
  • high NADH is a property that is conserved between normal and cancerous stem cells
  • Previous studies have also shown that when non-CSCs and CSCs are both fed mitochondrial fuels (such as L-lactate or ketone bodies), that CSCs quantitatively produce more NADH in response to this stimulus
  • CSCs may be strictly dependent on NADH to maintain their enhanced mitochondrial function
  • The Noble Prize winner, Linus Pauling, was among the first to describe and clinically test the efficacy of Vitamin C, as a relatively non-toxic anti-cancer agent
  • Vitamin C has two mechanisms of action. First, it is a potent pro-oxidant, that actively depletes the reduced glutathione pool, leading to cellular oxidative stress and apoptosis in cancer cells. Moreover, it also behaves as an inhibitor of glycolysis, by targeting the activity of GAPDH, a key glycolytic enzyme.
  • Here, we show that Vitamin C can also be used to target the CSC population, as it is an inhibitor of energy metabolism that feeds into the mitochondrial TCA cycle and OXPHOS
  • Vitamin C may prove to be promising agent for new clinical trials, aimed at testing its ability to reduce CSC activity in cancer patients, as an add-on to more conventional therapies, to prevent tumor recurrence, further disease progression and metastasis
  • Interestingly, a breast cancer based clinical study has already shown that the use of Vitamin C, concurrent with or within 6 months of chemotherapy, significantly reduces both tumor recurrence and patient mortality
  • CAPE quantitatively reduces mitochondrial oxygen consumption (OCR), while inducing a reactive increase in glycolysis (ECAR). As such, it potently inhibits mammosphere formation with an IC-50 of ~2.5 µM. Similarly, it also significantly inhibits cell migration
  • we also demonstrate that 7 different inhibitors of key energetic pathways can be used to effectively block CSC propagation, including three natural products (silibinin, ascorbic acid and CAPE). Future studies will be necessary to test their potential for clinical benefit in cancer patients.
  •  
    The future of cancer therapy is cancer stem cells.  Study finds that Vitamin C, silymarin, and bee propolis blocks mitochondrial energy pathways in cancer stem cells.  Vitamin C is a known glycolytic inhbitor. Vitamin C was found to inhibit glycolysis via GAPDH targeting to inhibit the energy pathways of the mitochondria in CSCs.  The authors propse that Vitamin C can be used as add on therapies for conventional therapies to specifically attack the CSCs and their contribution to recrurence, treatment resistance, and metastasis potential all in addition to the ability of vitamin C to reduce the side effects of chemotherapy.

Tricycle For Disabled Children - 0 views

  •  
    The tricycles are individually designed to meet the needs of each disabled child and help provide physiotherapy, build muscle tone and promote play. Italso help benefit growth and development in children with disabilities, enabling them to keep active and retain their independence. Disabled children get huge physical and emotional benefits from having the specially tricycles, which are each custom made to suit the individual child's needs. Riding a tricycle provides both fun and fitness, and is a therapeutic activity that allows children to exercise their lower extremities. As the muscles move through cycling motions, they are flexed, extended and stretched. This range of motion is crucial for children with disabilities, because muscles are incapable of keeping up with bone growth unless fully extended. Tricycles are provided to severely disabled children and adults and come in two sizes, 20 inch and 24 inch models. These trikes are grant funded and to qualify for one of these, an individual must suffer from a condition such as, but not limited to, Cerebral Palsy, Down Syndrome, Traumatic Brain Injury or Autism. Trunk support system is ideal for riders who have trouble remaining upright while seated. An optional headrest is available. A headrest can be purchased with either a flat or contoured headpiece, and adjusts both horizontally and vertically for optimum positioning. The Front Pulley System maintains a level pedal position for children whose extreme tone forces the front of the pedal downward. Turn the oval knob to raise and lower the handlebar. A handbrake for the conventional handlebar will arrive installed on Large tricycle. Open access combined with a low transfer step makes it easy to get on and off trikes.

    Wheelchair category (standard, transport, power, etc.) could be classified as a reclining wheelchairs, since the product class is built around one key feature: the capability to adjust the backrest and/or footrest into a reclined position. This feature is especially important to users who find it difficult or impossible to sit in a fully upright position, and users who sleep in their chairs frequently. For those that are looking for a more portable chair, however, products from this category may not be a great fit. When compared with a similar, non-reclining chair, a reclining wheelchair tends to weigh more and - unlike other manual models - manual wheelchairs that recline typically aren't foldable.

  • diacylglycerol O-acyltransferase 2 (DGAT2), mechanistically implicated in this differential storage, [10] is regulated by dihydrotestosterone, [11] suggesting a potential role for androgens to influence the genetic predisposition to either the MHO or MONW phenotype.
  • bariatric surgery achieves 10%-30% long-term weight loss in controlled studies
  • The fact that obese men have lower testosterone compared to lean men has been recognized for more than 30 years
  • Reductions in testosterone levels correlate with the severity of obesity and men
  • epidemiological data suggest that the single most powerful predictor of low testosterone is obesity, and that obesity is a major contributor of the age-associated decline in testosterone levels.
  • healthy ageing by itself is uncommonly associated with marked reductions in testosterone levels
  • obesity blunts this LH rise, obesity leads to hypothalamic-pituitary suppression irrespective of age which cannot be compensated for by physiological mechanisms
  • Reductions in total testosterone levels are largely a consequence of reductions in sex hormone binding globulin (SHBG) due to obesity-associated hyperinsulinemia
  • although controversial, measurement of free testosterone levels may provide a more accurate assessment of androgen status than the (usually preferred) measurement of total testosterone in situations where SHBG levels are outside the reference range
  • SHBG increases with age
  • marked obesity however is associated with an unequivocal reduction of free testosterone levels, where LH and follicle stimulating hormone (FSH) levels are usually low or inappropriately normal, suggesting that the dominant suppression occurs at the hypothalamic-pituitary level
  • adipose tissue, especially when in the inflamed, insulin-resistant state, expresses aromatase which converts testosterone to estradiol (E 2 ). Adipose E 2 in turn may feedback negatively to decrease pituitary gonadotropin secretion
  • diabetic obesity is associated with decreases in circulatory E 2

    Tricycles make cycling accessible to all, whatever personal challenges. There are a wide range of disability cycles that suit people with a variety of learning and physical disabilities, as well as health issues. Tricycles have 3 wheels, which means that the rider does not need to be able to balance. This is particularly useful for people with learning disabilities, such as Dyspraxia, and those recovering from illnesses. Tricycles can be fitted with foot plates to make it easier for riders to rotate the pedals and they come in upright or recumbent (horizontal sitting position). For adults and children with balance issues, stabilisers can also be fitted to standard bikes, which makes them more like tricycles. Tricycles come in a variety of accessible styles for people of all abilities including many persons with spinal cord injury disabilities. Tricycles is a great upper body workout and can provide a great sense of freedom for persons with disabilities. While the high cost prevents many from enjoying Tricycles they are steadily growing in popularity. Tricycle Deluxe Double Hand Drive: Frame : Made by E.R.W.

  • The relationship of low testosterone to MetS often is considered to be bidirectional; however, the relationships probably are not direct
  • Many of the components of the MetS are recognized risk factors for the development of cardiovascular disease (CVD)
  • Multiple cross-sectional studies have found low TT and low sex hormone binding globulin (SHBG) levels in Caucasian and African-American men with the MetS, irrespective of age
  • ...20 more annotations...
  • Low TT and SHBG levels also are prevalent in Chinese [7],[8] and Korean [9] men with the MetS
  • Normally 40%-50% of TT is bound to SHBG, so reducing SHBG levels will decrease TT.
  • Hyperinsulinism suppresses SHBG synthesis and secretion by the liver
  • significant increase in SHBG levels occurred after acutely lowering insulin levels in obese men
  • Estradiol levels are increased in men with the MetS, and they are positively correlated with the number of abnormal components of the MetS.
  • Although it is known that estrogen will increase SHBG levels, apparently the hyperinsulinism associated with obesity has a greater effect on SHBG levels
  • Estradiol also can inhibit luteinizing hormone (LH) secretion
  • Inflammatory cytokines are thought to have a direct effect on the pituitary to reduce LH secretion [15] and also a direct effect on Leydig cell secretion of testosterone
  • Low TT Levels have been shown to predict development of the MetS in men with normal BMI
  • Men in the lowest quartiles of serum TT, calculated free testosterone (cFT) and SHBG at baseline had the highest odds ratios for developing the MetS or DM during the 11 years follow-up
  • More recently, investigators conducting population-based studies have reported that only SHBG is associated with future development of the MetS
  • Additional evidence that low TT increases the risk of MetS comes from androgen deprivation treatment of prostate cancer
  • Low TT and low bioavailable testosterone (bT) were each significantly associated with elevated 20 years risk of CVD mortality in an older population in which cause-specific mortality was age, adiposity, and lifestyle-adjusted.
  • combination of low bT and ATP III-defined MetS is associated with increased cardiovascular mortality in men aged 40 years and above
  • in elderly men, testosterone may weakly protect against CVD. Alternatively, low TT may indicate poor general health
  • Muraleedharan and Jones [27] concluded that there is convincing evidence that low T is a biomarker for disease severity and mortality.
  • The evidence that TRT improves insulin sensitivity and glucose control is conflicted
  • It is widely recognized that testosterone treatment can reduce fat mass and increase lean body mass; however, until recently most reports have not been associated with much weight loss
  • Changes in body composition and weight loss are considered potential mechanisms by which testosterone treatment improves insulin sensitivity and glucose control in patients with diabetes. Effects on inflammatory cytokines [38] and changes in oxidative metabolism [39] also have been reported to improve glucose metabolism.
  • Testosterone replacement therapy has been reported to improve some or all of the components of the MetS.

Wheelchair Pediatric - 0 views

  •  
    When it comes to wheelchairs, young children have a different set of needs than adults. Aesthetically, devices designed for kids are often sleek and colorful, and functionally, they are typically lightweight and adjustable. As any parent knows, young people don't stay the same size for long and since a wheelchair is a major purchase don't want a simple growth spurt to render it useless. That's why kids wheelchair category offers models that feature seat width and depth adjustability, elevating legrests, and other versatile features. Pediatric walkers differ from adult walkers in several ways. For one, walking aids for children are usually adjustable, taking growth patterns into account; but many models also provide gait training and postural correction. Those caring for kids in their formative years must be concerned about more than just the young person's mobility, they must also consider their development. Cerebral Palsy Wheelchair: Cerebral Palsy Wheelchair Description: The model designed for cerebral palsy child only.

Cancer cells metabolically "fertilize" the tumor microenvironment with hydrogen peroxid... - 0 views

  • reducing oxidative stress with powerful antioxidants, is an important strategy for cancer prevention, as it would suppress one of the key early initiating steps where DNA damage and tumor-stroma metabolic-coupling begins. This would prevent cancer cells from acting as metabolic “parasites
  • Oxidative stress in cancer-associated fibroblasts triggers autophagy and mitophagy, resulting in compartmentalized cellular catabolism, loss of mitochondrial function, and the onset of aerobic glycolysis, in the tumor stroma. As such, cancer-associated fibroblasts produce high-energy nutrients (such as lactate and ketones) that fuel mitochondrial biogenesis and oxidative metabolism in cancer cells. We have termed this new energy-transfer mechanism the “reverse Warburg effect.
  • Then, oxidative stress, in cancer-associated fibroblasts, triggers the activation of two main transcription factors, NFκB and HIF-1α, leading to the onset of inflammation, autophagy, mitophagy and aerobic glycolysis in the tumor microenvironment

  • oxidative stress and ROS, produced in cancer-associated fibroblasts, has a “bystander effect” on adjacent cancer cells, leading to DNA damage, genomic instability and aneuploidy, which appears to be driving tumor-stroma co-evolution
  • tumor cells produce and secrete hydrogen peroxide, thereby “fertilizing” the tumor microenvironment and driving the “reverse Warburg effect.”
  • This type of stromal metabolism then produces high-energy nutrients (lactate, ketones and glutamine), as well as recycled chemical building blocks (nucleotides, amino acids, fatty acids), to literally “feed” cancer cells
  • loss of stromal caveolin (Cav-1) is sufficient to drive mitochondrial dysfunction with increased glucose uptake in fibroblasts, mimicking the glycolytic phenotype of cancer-associated fibroblasts.
  • oxidative stress initiated in tumor cells is transferred to cancer-associated fibroblasts.
  • Then, cancer-associated fibroblasts show quantitative reductions in mitochondrial activity and compensatory increases in glucose uptake, as well as high ROS production
  • These findings may explain the prognostic value of a loss of stromal Cav-1 as a marker of a “lethal” tumor microenvironment
  • aerobic glycolysis takes place in cancer-associated fibroblasts, rather than in tumor cells, as previously suspected.
  • our results may also explain the “field effect” in cancer biology,5 as hydrogen peroxide secreted by cancer cells, and the propagation of ROS production, from cancer cells to fibroblasts, would create an increasing “mutagenic field” of ROS production, due to the resulting DNA damage
  • Interruption of this process, by addition of catalase (an enzyme that detoxifies hydrogen peroxide) to the tissue culture media, blocks ROS activity in cancer cells and leads to apoptotic cell death in cancer cells
  • In this new paradigm, cancer cells induce oxidative stress in neighboring cancer-associated fibroblasts
  • cancer-associated fibroblasts have the largest increases in glucose uptake
  • cancer cells secrete hydrogen peroxide, which induces ROS production in cancer-associated fibroblasts
  • Then, oxidative stress in cancer-associated fibroblast leads to decreases in functional mitochondrial activity, and a corresponding increase in glucose uptake, to fuel aerobic glycolysis
  • cancer cells show significant increases in mitochondrial activity, and decreases in glucose uptake
  • fibroblasts and cancer cells in co-culture become metabolically coupled, resulting in the development of a “symbiotic” or “parasitic” relationship.
  • cancer-associated fibroblasts undergo aerobic glycolysis (producing lactate), while cancer cells use oxidative mitochondrial metabolism.
  • We have previously shown that oxidative stress in cancer-associated fibroblasts drives a loss of stromal Cav-1, due to its destruction via autophagy/lysosomal degradation
  • a loss of stromal Cav-1 is sufficient to induce further oxidative stress, DNA damage and autophagy, essentially mimicking pseudo-hypoxia and driving mitochondrial dysfunction
  • loss of stromal Cav-1 is a powerful biomarker for identifying breast cancer patients with early tumor recurrence, lymph-node metastasis, drug-resistance and poor clinical outcome
  • this type of metabolism (aerobic glycolysis and autophagy in the tumor stroma) is characteristic of a lethal tumor micro-environment, as it fuels anabolic growth in cancer cells, via the production of high-energy nutrients (such as lactate, ketones and glutamine) and other chemical building blocks
  • the upstream tumor-initiating event appears to be the secretion of hydrogen peroxide
  • one such enzymatically-active protein anti-oxidant that may be of therapeutic use is catalase, as it detoxifies hydrogen peroxide to water
  • numerous studies show that “catalase therapy” in pre-clinical animal models is indeed sufficient to almost completely block tumor recurrence and metastasis
  • by eliminating oxidative stress in cancer cells and the tumor microenvironment,55 we may be able to effectively cut off the tumor's fuel supply, by blocking stromal autophagy and aerobic glycolysis
  • breast cancer patients show systemic evidence of increased oxidative stress and a decreased anti-oxidant defense, which increases with aging and tumor progression.68–70 Chemotherapy and radiation therapy then promote further oxidative stress.69 Unfortunately, “sub-lethal” doses of oxidative stress during cancer therapy may contribute to tumor recurrence and metastasis, via the activation of myofibroblasts.
  • a loss of stromal Cav-1 is associated with the increased expression of gene profiles associated with normal aging, oxidative stress, DNA damage, HIF1/hypoxia, NFκB/inflammation, glycolysis and mitochondrial dysfunction
  • cancer-associated fibroblasts show the largest increases in glucose uptake, while cancer cells show corresponding decreases in glucose uptake, under identical co-culture conditions
  • Thus, increased PET glucose avidity may actually be a surrogate marker for a loss of stromal Cav-1 in human tumors, allowing the rapid detection of a lethal tumor microenvironment.
  • it appears that astrocytes are actually the cell type responsible for the glucose avidity.
  • In the brain, astrocytes are glycolytic and undergo aerobic glycolysis. Thus, astrocytes take up and metabolically process glucose to lactate.7
  • Then, lactate is secreted via a mono-carboxylate transporter, namely MCT4. As a consequence, neurons use lactate as their preferred energy substrate
  • both astrocytes and cancer-associated fibroblasts express MCT4 (which extrudes lactate) and MCT4 is upregulated by oxidative stress in stromal fibroblasts.34
  • In accordance with the idea that cancer-associated fibroblasts take up the bulk of glucose, PET glucose avidity is also now routinely used to measure the extent of fibrosis in a number of human diseases, including interstitial pulmonary fibrosis, postsurgical scars, keloids, arthritis and a variety of collagen-vascular diseases.
  • PET glucose avidity and elevated serum inflammatory markers both correlate with poor prognosis in breast cancers.
  • PET signal over-estimates the actual anatomical size of the tumor, consistent with the idea that PET glucose avidity is really measuring fibrosis and inflammation in the tumor microenvironment.
  • human breast and lung cancer patients can be positively identified by examining their exhaled breath for the presence of hydrogen peroxide.
  • tumor cell production of hydrogen peroxide drives NFκB-activation in adjacent normal cells in culture6 and during metastasis,103 directly implicating the use of antioxidants, NFκB-inhibitors and anti-inflammatory agents, in the treatment of aggressive human cancers.
