    Pediatric wheelchairs enable child or teen to participate in all types of daily activities. Pediatric wheelchairs are lightweight, portable, and convenient for use at school, day programs, doctor visits, and recreation with family and friends. Pediatric wheelchairs comes in wide range of sizes and vibrant colors for every lightweight wheelchair. A variety of positioning options are also available. Pediatric wheelchairs are manufactured with unsurpassed quality and style, specializing in compact-folding, lightweight wheelchairs for children of all ages - from toddlers to teens! Custom built to child's specific needs, mobility aids offer rehabilitative benefits for physical disabilities from Cerebral Palsy to Autism. Pediatric, or child wheelchairs, are mobile aids designed for and used by children. Children require the use of a wheelchair for many different reasons, some may have suffered head injuries, some have muscular dystrophy or cerebral palsy, some are amputees, and others only have an occasional use of their wheelchairs in lieu of a walking device or crutches. Certain types of pediatric wheelchairs are built to expand in size to accommodate increased bulk and weight by altering a cross balance on the bottom of the chair. The front frames for the legs can be lengthened as child's legs grow longer. For a pediatrician seeking to prescribe a Pediatric Wheelchair, must be sure that the patient has the proper upper body strength to use one. If the patient is too weak for self movement, the practitioner would be better to consider a powered wheelchair for mobility. While Pediatric Wheelchairs are smaller and can be just as manuverable as scooters, that depends upon the patient's own abilities in steering the chair. These are factors that the doctor must think about before recommending what type of wheelchair a patient should get. Pediatric Wheelchair with a body contouring S-Shaped seat frame and contoured armrests provides the user with all day comfort an

Portable Wheelchair Provides Stage AccessibilityPortable chair frames can be constructe... - 0 views

  •  
    Portable chair frames can be constructed of either steel or aluminum and have weights anywhere from 15 lbs. and 45 lbs. depending on the model. All chairs will fold from side to side and some have folding back the make transporting and storage easier. Most chairs have weight capacity of 250 lbs. But the heavy duty models will hold up to about 450 lbs. Of course, a chair which will hold 450 lbs. Will be a much more heavily constructed and will push the weight towards the 45 lb. weight. The most common wheel configuration for portable chairs is four 8\" casters with solid tires. The front two casters will swivel to enable turning. On some models the rear two wheels may be 12\" in diameter instead of 8\" and have air tires insted of solid tires. The larger wheels will give a little bit softer ride and traverse rough terrain a little better. They fold up in interesting ways to collapse to the size of a suitcase when not in use and are usually large enough to cover one or two stairs when extended. It is important to consider their weight and the person who would most often be carrying the ramp and setting it up.

BMC Cancer | Full text | A lactate shuttle system between tumour and stromal cells is a... - 0 views

  • Under hypoxic conditions, tumour cells primarily use glycolysis for energy, producing lactate, which is expelled to the tumour microenvironment, allowing tumours to continue their glycolytic activity
  • Sonveaux et al. showed that lactate, which is generally considered a waste product, is preferred over glucose by oxidative tumour cells as their primary energy source
  • MCT4 is a low-affinity transporter, which is abundant in highly glycolytic muscle cells and is one of the many target genes of hypoxia-inducible factor 1 alpha (HIF-1α)
  • ...8 more annotations...
  • Other targets of HIF-1α include glucose transporter-1 (GLUT-1), the main transporter involved in glucose uptake [9,10]; lactate dehydrogenase V (LDHV), which is responsible for the conversion of pyruvate into lactate; pyruvate dehydrogenase kinase isozyme 1 (PDK1), which is responsible for the phosphorylation and consequent inactivation of pyruvate dehydrogenase (PDH); and carbonic anhydrase IX (CAIX), a hypoxia-related protein involved in pH regulation [11]. Alpha-methylacyl-CoA racemase (AMACR), pristanoyl-CoA oxidase (ACOX-3) and D-bifunctional protein (DBP), are also important fatty acid oxidation-related proteins in prostate cancer
  • the essential role played by the cross-talk between stroma and epithelium in carcinogenesis and prostate cancer progression has been increasingly recognised
  • strong membranous expression of MCT1 was consistently observed in cancer cells, suggesting a role for MCT1 in the transport of lactate into tumour cells from the acidic extracellular matrix, suggesting that lactate might be used as a fuel by oxidative cancer cells.
  • Our hypothesis is in agreement with those of Fiaschi et al.[17], who describe the metabolic reprogramming of CAFs towards the Warburg phenotype as a result of contact with prostate cancer cells
  • Using in vitro studies, they showed lactate production and efflux by de novo expressed MCT4 in CAFs and also demonstrated that, upon contact with CAFs, prostate cancer cells were reprogrammed towards aerobic metabolism, with an increase in lactate uptake via the lactate transporter MCT1.
  • pharmacological inhibition of MCT1-mediated lactate uptake dramatically affected PCa cell survival and tumour outgrowth
  • In this model, “energy transfer” or “metabolic coupling” between the tumour stroma and epithelial cancer cells fuels tumour growth and metastasis via oxidative mitochondrial metabolism in anabolic cancer cells
  • the concomitant expression of MCT1 in tumour cells and MCT4 in fibroblasts in the same tissue is clinically significant, and associated with poor prognosis.
  •  
    Study confirms the importance of the crosstalk between cancer cells and CAFs via MCTs in prostate cancer.

    Travel wheelchair assists people to become more mobile and independent. There are many different types of wheelchairs that are used for various reasons. It is important to understand the limitations and safe operation of whatever wheelchair choose or need. The travel chair seat size (width and depth), seat-to-floor height, footrests/leg rests, front caster outriggers, adjustable backrests, controls, and many other features can be customized on, or added to, many basic models, while some users, often those with specialized needs, may have wheelchairs custom-built. A single-arm drive enables the user to turn either left or right while the two-armed drive enables user to move forward or backward on a straight line. Another type of wheelchair commonly used is a lever-drive wheelchair. This type of chair enables the user to move forward by pumping the lever back and forth. Travel Wheelchair is designed with unique S shaped seat which provides pressure relief and prevents slippage. Equipped with wide arm pads the wheelchair provides extra support for the user. The chair material is treated with an Aegis Microbe shield to reduce the likelihood of staining and odours.

    Ergonomic Wheelchair often spend a lot of time leaning on armrests or a table exactly because they are not being supported with good posture in their chairs. This is a matter of seat angle and back angle, adjusting them according to body shape and degree of upper body balance. Poor seating makes slump, trying to get stable. The optimal posture is more upright, allowing spine to support. Ergonomic chairs are designed to confirm to a person's physical dimensions, allowing them to sit naturally and comfortably for long periods of time, while reducing the risk of pressure ulcers. Ergonomic system (Intelligent s-shaped ergonomic seating) provides efficient pressure relief by spreading weight over a greater area, at the same time provides stabilization and reduced sliding. With their lightweight frames and seats designed to reduce or prevent pressure points, ergonomic wheelchairs provide a comfortable option for mobility impaired users who have the upper body strength to propel themselves, or a caregiver strong enough to do so.

Pharmacologic ascorbic acid concentrations selectively kill cancer cells: Action as a p... - 0 views

  • Taken together, these data indicate that ascorbate at concentrations achieved only by i.v. administration may be a pro-drug for formation of H2O2, and that blood can be a delivery system of the pro-drug to tissues.
  • These findings give plausibility to i.v. ascorbic acid in cancer treatment, and have unexpected implications for treatment of infections where H2O2 may be beneficial
  • pharmacologic concentrations of ascorbate killed cancer but not normal cells, that cell death was dependent only on extracellular but not intracellular ascorbate, and that killing was dependent on extracellular hydrogen peroxide (H2O2) formation with ascorbate radical as an intermediate
  • ...48 more annotations...
  • Our data show that ascorbic acid selectively killed cancer but not normal cells, using concentrations that could only be achieved by i.v. administration
  • Ascorbate-mediated cell death was due to protein-dependent extracellular H2O2 generation, via ascorbate radical formation from ascorbate as the electron donor. Like glucose, when ascorbate is infused i.v., the resulting pharmacologic concentrations should distribute rapidly in the extracellular water space (42). We showed that such pharmacologic ascorbate concentrations in media, as a surrogate for extracellular fluid, generated ascorbate radical and H2O2. In contrast, the same pharmacologic ascorbate concentrations in whole blood generated little detectable ascorbate radical and no detectable H2O2. These findings can be accounted for by efficient and redundant H2O2 catabolic pathways in whole blood (e.g., catalase and glutathione peroxidase) relative to those in media or extracellular fluid
  • ascorbic acid administered i.v. in pharmacologic concentrations may serve as a pro-drug for H2O2 delivery to the extracellular milieu
  • H2O2 generated in blood is normally removed by catalase and glutathione peroxidase within red blood cells, with internal glutathione providing reducing equivalents
  • The electron source for glutathione is NADPH from the pentose shunt, via glucose-6-phosphate dehydrogenase. If activity of this enzyme is diminished, the predicted outcome is impaired H2O2 removal causing intravascular hemolysis, the observed clinical finding.
    • Nathan Goodyear
       
      The mechansism here is inadequate recycling of GSH due to lack of G6PD, build up of intracellular H2O2 and RBC lysis--hemolysis.
  • Only recently has it been understood that the discordant clinical findings can be explained by previously unrecognized fundamental pharmacokinetics properties of ascorbate
  • Intracellular transport of ascorbate is tightly controlled in relation to extracellular concentration
  • Intravenous ascorbate infusion is expected to drastically change extracellular but not intracellular concentrations
  • For i.v. ascorbate to be clinically useful in killing cancer cells, pharmacologic but not physiologic extracellular concentrations should be effective, independent of intracellular ascorbate concentrations.
    • Nathan Goodyear
       
      accumulation of extracellular vitamin C is the effect.
  • It is unknown why ascorbate, via H2O2, killed some cancer cells but not normal cells.
  • There was no correlation with ascorbate-induced cell death and glutathione, catalase activity, or glutathione peroxidase activity.
  • H2O2, as the product of pharmacologic ascorbate concentrations, has potential therapeutic uses in addition to cancer treatment, especially in infections
  • Neutrophils generate H2O2 from superoxide,
  • i.v. ascorbate is effective in some viral infections
  • H2O2 is toxic to hepatitis C
  • Use of ascorbate as an H2O2-delivery system against sensitive pathogens, viral or bacterial, has substantial clinical implications that deserve rapid exploration.
  • Recent pharmacokinetics studies in men and women show that 10 g of ascorbate given i.v. is expected to produce plasma concentrations of nearly 6 mM, which are >25-fold higher than those concentrations from the same oral dose
  • As much as a 70-fold difference in plasma concentrations is expected between oral and i.v. administration,
  • Complementary and alternative medicine practitioners worldwide currently use ascorbate i.v. in some patients, in part because there is no apparent harm
  • Human Burkitt's lymphoma cells
  • We first investigated whether ascorbate in pharmacologic concentrations selectively affected the survival of cancer cells by studying nine cancer cell lines
  • Clinical pharmacokinetics analyses show that pharmacologic concentrations of plasma ascorbate, from 0.3 to 15 mM, are achievable only from i.v. administration
  • plasma ascorbate concentrations from maximum possible oral doses cannot exceed 0.22 mM because of limited intestinal absorption
  • For five of the nine cancer cell lines, ascorbate concentrations causing a 50% decrease in cell survival (EC50 values) were less than 5 mM, a concentration easily achievable from i.v. infusion
  • All tested normal cells were insensitive to 20 mM ascorbate.

      meaning safe.
  • Lymphoma cells were selected because of their sensitivity to ascorbate
  • As ascorbate concentration increased, the pattern of death changed from apoptosis to pyknosis/necrosis, a pattern suggestive of H2O2-mediated cell death
  • Apoptosis occurred by 6 h after exposure, and cell death by pyknosis was ≈90% at 14 h after exposure

      work continued beyond the IVC therapy itself
  • In contrast to lymphoma cells, there was little or no killing of normal lymphocytes and monocytes by ascorbate
  • Ascorbate is transported into cells as such by sodium-dependent transporters, whereas dehydroascorbic acid is transported into cells by glucose transporters and then immediately reduced internally to ascorbate
  • Whether or not intracellular ascorbate was preloaded, extracellular ascorbate induced the same amount and type of death.
  • extracellular ascorbate in pharmacologic concentrations mediates death of lymphoma cells by apoptosis and pyknosis/necrosis, independently of intracellular ascorbate.
  • H2O2 as the effector species mediating pharmacologic ascorbate-induced cell death
  • Superoxide dismutase was not protective
  • Because these data implicated H2O2 in cell killing, we added H2O2 to lymphoma cells and studied death patterns using nuclear staining (19, 28). The death patterns found with exogenous H2O2 exposure were similar to those found with ascorbate
  • For both ascorbate and H2O2, death changed from apoptosis to pyknosis/necrosis as concentrations increased
  • Sensitivity to direct exposure to H2O2 was greater in lymphoma cells compared with normal lymphocytes and normal monocytes
  • There was no association between the EC50 for ascorbate-mediated cell death and intracellular glutathione concentrations, catalase activity, or glutathione peroxidase activity
  • H2O2 generation was dependent on time, ascorbate concentration, and the presence of trace amounts of serum in media
  • ascorbate radical is a surrogate marker for H2O2 formation.
  • whatever H2O2 is generated should be removed by glutathione peroxidase and catalase within red blood cells, because H2O2 is membrane permeable
  • The data are consistent with the hypothesis that ascorbate in pharmacologic concentrations is a pro-drug for H2O2 generation in the extracellular milieu but not in blood.
  • The occurrence of one predicted complication, oxalate kidney stones, is controversial
  • In patients with glucose-6-phosphate dehydrogenase deficiency, i.v. ascorbate is contraindicated because it causes intravascular hemolysis
  • ascorbate at pharmacologic concentrations in blood is a pro-drug for H2O2 delivery to tissues.
  • ascorbate, an electron-donor in such reactions, ironically initiates pro-oxidant chemistry and H2O2 formation
  • data here showed that ascorbate initiated H2O2 formation extracellularly, but H2O2 targets could be either intracellular or extracellular, because H2O2 is membrane permeant
    • Nathan Goodyear
       
      the conversion of ascorbate to H2O2 occurs extracellular
  • More than 100 patients have been described, presumably without glucose-6-phosphate dehydrogenase deficiency, who received 10 g or more of i.v. ascorbate with no reported adverse effects other than tumor lysis

Understanding lipoproteins as transporters of cholesterol and other lipids - 0 views

  • the density of each lipoprotein is clearly in a constant state of flux
  • Two lipoprotein fractions are primarily involved in transport of lipid to peripheral tissues, very low density lipoproteins (VLDL) from the liver and chylomicrons from the intestinal tract
  • As lipid is removed from these two fractions, the density of each fraction increases, thereby transforming VLDL into intermediate-density lipoprotein (IDL) and ultimately LDL, and chylomicrons into chylomicron remnants
  • ...5 more annotations...
  • LDL-cholesterol has been described, and overly simplified, as “bad cholesterol” and HDL-cholesterol as “good cholesterol.”
  • HDL, is primarily involved in returning lipid, largely cholesterol, to the liver in a process called reverse cholesterol transport
  • Two primary subfractions of HDL have been classified as the higher-density HDL3, and the less dense, more lipid-filled HDL2
  • Recent investigations are also suggesting that smaller, denser lipoproteins are associated with increased risk of atherosclerotic development
  • lipoproteins as transporters of lipid
  •  
    Brief, but good review of lipoproteins and apoliproteins.
