    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. Wheelchair category offers models that feature seat width and depth adjustability, elevating legrests, and other versatile features. As a weight-bearing activity is critical to proper physical and mental function-which is why children with cerebral palsy, who may sit for stretches in a wheelchair and typically are unable to stand on their own, can benefit greatly from pediatric standers as part of a comprehensive pediatric rehabilitation program. Pediatric standers are offered in passive, active and mobile formats: Passive standers stay in one place and feature a support surface, active standers allow reciprocal movement of the extremities while in a standing position, and mobile standers enable users to self-propel. Cerebral Palsy Wheelchair: Cerebral Palsy Wheelchair Description: The model designed for cerebral palsy child only. Ultra light weight aluminium alloy frame. Seat Width 38 cms (15").

    Cerebral palsy (CP) is a group of conditions caused by medical abnormalities in the development of a fetus or the early life of a child. These lead to damage or delayed development in the brain. The disorder is permanent and, though it does not worsen with age, the level of functionality of a person with cerebral palsy varies widely: in some cases, effects may be very minor, while in others, movement is impaired to the extent that a wheelchair is required. Common complications associated with CP vary by the type of CP disorder but can include vision problems, seizures, learning disabilities, and issues speaking, writing, and performing other tasks. Cerebral palsy causes problems with muscle tone, movement, balance and/or coordination. Symptoms and effects range from mild to severe. In some infants, problems are evident soon after birth. In others, diagnosis comes in later infancy or toddlerhood. Cerebral Palsy Wheelchair Description: The model designed for cerebral palsy child only. Ultra light weight aluminium alloy frame.

brain cancer

shared by Nathan Goodyear on 17 Jun 13 - No Cached
  • Glutamine is a major metabolic fuel for both brain tumor cells and tumor-associated macrophages (TAMs)
  • the malignant phenotype of brain tumor cells that survive radiotherapy is often greater than that of the cells from the original tumor.
  • Conventional chemotherapy has faired little better than radiation therapy for the long-term management of malignant brain cancer
  • ...37 more annotations...
  • most conventional radiation and brain cancer chemotherapies can enhance glioma energy metabolism and invasive properties, which would contribute to tumor recurrence and reduced patient survival [34].
  • We contend that all cancer regardless of tissue or cellular origin is a disease of abnormal energy metabolism
  • complex disease phenotypes can be managed through self-organizing networks that display system wide dynamics involving oxidative and non-oxidative (substrate level) phosphorylation
  • As long as brain tumors are provided a physiological environment conducive for their energy needs they will survive; when this environment is restricted or abruptly changed they will either grow slower, growth arrest, or perish [8] and [19]
  • New information also suggests that ketones are toxic to some human tumor cells and that ketones and ketogenic diets might restrict availability of glutamine to tumor cells [68], [69] and [70].
  • The success in dealing with environmental stress and disease is therefore dependent on the integrated action of all cells in the organism
  • Tumor cells survive in hypoxic environments not because they have inherited genes making them more fit or adaptable than normal cells, but because they have damaged mitochondria and have thus acquired the ability to derive energy largely through substrate level phosphorylation
  • Cancer cells survive and multiply only in physiological environments that provide fuels (mostly glucose and glutamine) subserving their requirement for substrate level phosphorylation
  • Integrity of the inner mitochondrial membrane is necessary for ketone body metabolism since β-hydroxybutyrate dehydrogenase, which catalyzes the first step in the metabolism of β-OHB to acetoacetate, interacts with cardiolipin and other phospholipids in the inner membrane
  • the mitochondria of many gliomas and most tumors for that matter are dysfunctional
  • Cardiolipin is essential for efficient oxidative energy production and mitochondrial function
  • Any genetic or environmental alteration in the content or composition of cardiolipin will compromise energy production through oxidative phosphorylation
  • The Crabtree effect involves the inhibition of respiration by high levels of glucose
  • the Warburg effect involves elevated glycolysis from impaired oxidative phosphorylation
  • the Crabtree effect can be reversible, the Warburg effect is largely irreversible because its origin is with permanently damaged mitochondria
  • The continued production of lactic acid in the presence of oxygen is the metabolic hallmark of most cancers and is referred to as aerobic glycolysis or the Warburg effect
  • We recently described how the retrograde signaling system could induce changes in oncogenes and tumor suppressor genes to facilitate tumor cell survival following mitochondrial damage [48].
  • In addition to glycolysis, glutamine can also increase ATP production under hypoxic conditions through substrate level phosphorylation in the TCA cycle after its metabolism to α-ketoglutarate
  • mitochondrial lipid abnormalities, which alter electron transport activities, can account in large part for the Warburg effect
  • targeting both glucose and glutamine metabolism could be effective for managing most cancers including brain cancer
  • The bulk of experimental evidence indicates that mitochondria are dysfunctional in tumors and incapable of generating sufficient ATP through oxidative phosphorylation
  • Cardiolipin defects in tumor cells are also associated with reduced activities of several enzymes of the mitochondrial electron transport chain making it unlikely that tumor cells with cardiolipin abnormalities can generate adequate energy through oxidative phosphorylation
  • The Crabtree effect involves the inhibition of respiration by high levels of glucose
  • Warburg effect involves elevated glycolysis from impaired oxidative phosphorylation
  • TCA cycle substrate level phosphorylation could therefore become another source of ATP production in tumor cells with impairments in oxidative phosphorylation
  • Caloric restriction, which lowers glucose and elevates ketone bodies [63] and [64], improves mitochondrial respiratory function and glutathione redox state in normal cells
  • DR naturally inhibits glycolysis and tumor growth by lowering circulating glucose levels, while at the same time, enhancing the health and vitality of normal cells and tissues through ketone body metabolism
  • DR is anti-angiogenic
  • DR also reduces angiogenesis in prostate and breast cancer
  • We suggest that apoptosis resistance arises largely from enhanced substrate level phosphorylation of tumor cells and to the genes associated with elevated glycolysis and glutaminolysis, e.g., c-Myc, Hif-1a, etc, which inhibit apoptosis
  • Modern medicine has not looked favorably on diet therapies for managing complex diseases especially when well-established procedures for acceptable clinical practice are available, regardless of how ineffective these procedures might be in managing the disease
  • More than 60 years of clinical research indicates that such approaches are largely ineffective in extending survival or improving quality of life
  • The process is rooted in the well-established scientific principle that tumor cells are largely dependent on substrate level phosphorylation for their survival and growth
  • Glucose and glutamine drive substrate level phosphorylation
  • targeting the glycolytically active tumor cells that produce pro-cachexia molecules, restricted diet therapies can potentially reduce tumor cachexia
  • It is important to recognize, however, that “more is not better” with respect to the ketogenic diet
  • Blood glucose ranges between 3.0 and 3.5 mM (55–65 mg/dl) and β-OHB ranges between 4 and 7 mM should be effective for tumor management

endurance athletes training heart health injury

shared by Nathan Goodyear on 09 Jan 15 - No Cached
  • In a cohort of well-trained athletes, we demonstrated that intense endurance exercise causes an acute reduction in RV function that increases with race duration and correlates with increases in biomarkers of myocardial injury
  • no relationship between LV function and biomarker levels
  • focal gadolinium enhancement and increased RV remodelling were more prevalent in those athletes with a longer history of competitive sport, suggesting that repetitive ultra-endurance exercise may lead to more extensive RV change and possible myocardial fibrosis
  • ...22 more annotations...
  • he cardiac impact of both acute and cumulative exercise is greatest on the RV.
  • Greater reductions in RV function occurred in those athletes competing for a longer duration, suggesting that the heart has a finite capacity to maintain the increased work demands of exercise
  • cardiac injury is greatest in the least trained
  • Previous investigators have documented reductions in RV function in less trained subjects over the marathon distance
  • We enrolled elite and subelite athletes and found a significant association between fitness (VO2max) and the reduction in post-race RVEF
  • Even after many years of detraining, cardiac dilation may not completely regress in elite athletes
  • The focus on well-trained athletes may be of particular relevance, given that they perform exercise of highest intensity and duration most frequently, and, thus, may be at a greater risk of cumulative injury.
  • The lack of correlation between increases in troponin and changes in LV function seen in this study has been previously interpreted as evidence that post-exercise elevations in cardiac biomarkers are benign.
  • a significant correlation between changes in RVEF and post-race biomarker levels and this relationship was even stronger in the athletes who completed the race of longest duration, the ultra-triathlon
  • The correlations with RVEF, but not LVEF, provide further evidence of the differential effects of intense exercise on RV and LV function
  • BNP release during intense exercise is associated with greater relative increases in RV systolic pressures, but not LV pressures
  • BNP may provide a measure of both acute RV load and the resultant fatigue which occurs when this load is sustained
  • It has been demonstrated that ventricular load increases with exercise intensity and is greater for the RV than the LV,29 thus potentially explaining why the RV is more susceptible to fatigue after prolonged exercise.
  • This study demonstrates, for the first time, an association between endurance exercise of increasing duration and structural, functional, and biochemical markers of cardiac dysfunction in highly trained athletes
  • Functional abnormalities were confined to the RV and were largely reversible 1 week following the event
  • there remained a significant minority of athletes in whom there was evidence of myocardial fibrosis in the interventricular septum
  • RV abnormalities may be acquired through cumulative bouts of intense exercise and provides direction for prospective investigations aimed at elucidating whether extreme exercise may promote arrhythmias in some athletes.
  • the acute injury and chronic remodelling of the myocardium both disproportionately affect the RV and it remains possible that the two are linked.
  • focal DGE was confined to the interventricular septum and commonly at the site of RV attachment
  • emerging evidence that intense endurance exercise may be associated with an excess in arrhythmic disorders, the mechanisms for which remain unexplained
  • RVEF (and not LVEF) was reduced in athletes with complex ventricular arrhythmias when compared with healthy athletes and non-athletes without arrhythmias
  • it is premature to conclude that these changes may represent a proarrhythmic substrate

IL-2 cancer immune system

shared by Nathan Goodyear on 17 Apr 18 - No Cached
  • IL-2 is one of the key cytokines with pleiotropic effects on the immune system
  • IL-2 as “T-cell growth factor”
  • approved for the treatment of metastatic renal cell carcinoma (1992) and later for metastatic melanoma (1998) by FDA
  • ...13 more annotations...
  • It is produced predominately by antigen-simulated CD4+ T cells, while it can also be produced by CD8+ cells, natural killer (NK) cells, and activated dendritic cells (DC)
  • IL-2 is an important factor for the maintenance of CD4+ regulatory T cells
  • plays a critical role in the differentiation of CD4+ T cells into a variety of subsets
  • It can promote CD8+ T-cell and NK cell cytotoxicity activity, and modulate T-cell differentiation programs in response to antigen, promoting naive CD4+ T-cell differentiation into T helper-1 (Th1) and T helper-2 (Th2) cells while inhibiting T helper-17 (Th17) differentiation
  • Of note, Tregs, which act to dampen the immune response, constitutively express high levels of α chain
  • IL-2Rα is unique to IL-2 and is expressed by a number of immune cells including T regulatory cells (Treg), activated CD4+ and CD8+T cells, B cells, mature DCs, endothelial cells
  • some investigators evaluated the efficacy of regimens containing low-dose IL-2
  • IL-2 can promote the activation and cell growth of T and NK cells
  • Unfortunately, not all of patients would benefit from targeted therapy and nearly all patients who initially respond to targeted inhibitors inevitably develop acquired resistance to the treatment
  • IL-2 also stimulates T-regulatory cells that constitutively express CTLA-4 and can suppress immune reactions. Hence, IL-2 might enhance antitumor reactivity in the presence of CTLA-4 blockade
  • both HD and low-dose IL-2 therapy preferentially induce the expansion of CD4+CD25+Foxp3+ Treg and the Treg level remains elevated after each cycle of HD IL-2 therapy
  • Due to rapid elimination and metabolism via the kidney, IL-2 has a short serum half-life of several minutes
  • HD IL-2-induced severe toxicities including vascular leak syndrome (VLS), pulmonary edema, hypotension, and heart toxicities

shared by Nathan Goodyear on 24 Mar 15 - No Cached
  • Histamine intolerance can develop through both increased availability of histamine and impaired histamine degradation
  • increased availability may be an endogenous histamine overproduction caused by allergies, mastocytosis, bacterias, gastrointestinal bleeding, or increased exogenous ingestion of histidine or histamine by food or alcohol
  • Other biogenic amines, such as putrescine, may also be involved in displacing histamine from its mucosal mucine linkage, which results in an increase of free absorbable histamine in circulation
  • ...2 more annotations...
  • the main cause of histamine intolerance is an impaired enzymatic histamine degradation caused by genetic or acquired impairment of the enzymatic function of DAO or HNMT
  • The main enzyme for metabolism of ingested histamine is diamine oxidase (DAO)
