What Is Dialysis? What Is Kidney Dialysis?
Dialysis is the artificial process of getting rid of waste (diffusion) and unwanted water (ultrafiltration) from the blood. This process is naturally done by our kidneys. Some people, however, may have failed or damaged kidneys which cannot carry out the function properly - they may need dialysis. In other words, dialysis is the artificial replacement for lost kidney function (renal replacement therapy). Dialysis may be used for people who have become ill and have acute kidney failure (temporary loss of kidney function), or for fairly stable patients who have permanently lost kidney function (stage 5 chronic kidney disease).

Stromal Marker For Breast Cancer Progression Identified

Dr. Arne Ostman and colleagues at the Karolinska Institutet in Stockholm have identified a stromal marker for breast cancer progression. They present these findings in the July 2009 issue of the American Journal of Pathology. Platelet-derived growth factor (PDGF) receptors are involved in multiple stages of cancer cell growth. However, the contribution of PDGFR expression in the stroma, or surrounding supportive tissue, of the tumor remains unclear. Paulsson et al therefore characterized PDGFR expression in stroma of various tumors, including lymphoma and colon, ovarian, prostate, lung, and breast cancer. They found highly variable PDGFR expression in solid tumors, with colon and prostate tumors expressing the highest stromal levels of one type of PDGFR, PDGFí²R. In breast cancer, stromal PDGFí²R expression in pre-menopausal breast cancer patients significantly correlated with negative prognosis. These data highlight the importance of examining stromal as well as malignant cell expression of PDGF receptors in disease prognosis. Paulsson et al suggest that "the findings in the present study of robust staining procedures for PDGF receptors should motivate continued studies of the response-predicative value of stromal PDGF receptor status."

a best guide on breast cancer. It covers all the essential topics and I really like this part of the information.
