Water and fluid : The alternate fuel of our body.

We know that food is our body fuel. Specially, the Glucose. Glucose is the main fuel of our body. But, do we know that water is our alternate fuel ?..............

Natural killer cell From Wikipedia, the free encyclopedia (Redirected from Natural Killer cell ) Jump to: navigation , search Natural killer cells (or NK cells ) are a type of cytotoxic lymphocyte critical to the innate immune system . The role NK cells play is analogous to that of cytotoxic T cells in the vertebrate adaptive immune response . NK cells provide rapid responses to virally infected cells and respond to tumor formation, acting at around 3 days after infection . Typically immune cells detect MHC presented on infected cell surfaces, triggering cytokine release causing lysis or apoptosis . NK cells are unique, however, as they have the ability to recognize stressed cells in the absence of antibodies and MHC, allowing for a much faster immune reaction. They were named “natural killers” because of the initial notion that they do not require activation in order...

Monoclonal Antibody Targets, Kills Leukemia Cells

Monoclonal Antibody Targets, Kills Leukemia Cells Researchers at the University of California, San Diego Moores Cancer Center have identified a humanized monoclonal antibody that targets and directly kills chronic lymphocytic leukemia (CLL) cells The findings, published in the online Early Edition of the Proceedings of the National Academy of Sciences on March 25, 2013 represent a potential new therapy for treating at least some patients with CLL, the most common type of blood cancer in the United States. CLL cells express high levels of a cell-surface glycoprotein receptor called CD44. Principal investigator Thomas Kipps, MD, PhD, Evelyn and Edwin Tasch Chair in Cancer Research, and colleagues identified a monoclonal antibody called RG7356 that specifically targeted CD44 and was directly toxic to cancer cells, but had little effect on normal B cells. Moreover, they found RG7356 induced CLL cells that expressed the protein ZAP-70 to undergo apoptosis or programmed cell dea...

Erythropoietin as a Retinal Angiogenic Factor in Proliferative Diabetic Retinopathy

Although vascular endothelial growth factor (VEGF) is a primary mediator of retinal angiogenesis, VEGF inhibition alone is insufficient to prevent retinal neovascularization. Hence, it is postulated that there are other potent ischemia-induced angiogenic factors. Erythropoietin possesses angiogenic activity, but its potential role in ocular angiogenesis is not established. METHODS We measured both erythropoietin and VEGF levels in the vitreous fluid of 144 patients with the use of radioimmunoassay and enzyme-linked immunosorbent assay. Vitreous proliferative potential was measured according to the growth of retinal endothelial cells in vitro and with soluble erythropoietin receptor. In addition, a murine model of ischemia-induced retinal neovascularization was used to evaluate erythropoietin expression and regulation in vivo. RESULTS The median vitreous erythropoietin level in 73 patients with proliferative diabetic retinopathy was significantly higher than that in 71 patients with...
