The current study was designed to evaluate the technique's potential for providing information useful for clinical decision-making in prostate cancer. The researchers used MR spectroscopy to analyze tissue samples from 82 pat...University of Manchester launches new anti-MRSA product

Silver ion, which is the active ingredient in IRGAGUARD also binds to the DNA of the cell stopping it from spreading. It does not degrade with time and is temperature-stable to well over 500...Radiofrequency ablation is effective long-term treatment for kidney tumors
...uency ablation (RFA) a minimally invasive way of destroying tissue is an effective, longlasting treatment for small kidney tumors in selected patients. In a followup to research published in 2003, the investigators found that RFA treatment of renal cell carcinoma, the most common kidney cancer, continued to...A new understanding of how immune system targets disease
...riods of time, T cells become armed and capable of destroying the pathogen in question. Sant's study provides the first proof that it is something about the invader epitope itself that drives and focuses T cell response, and not some action of enzymes inside the dendritic cell as once thought. The quality deter...Anti-inflammatory function of Alzheimer's disease drugs revealed
...s in a more efficient way than known heretofore by destroying the molecular antecedent (messenger RNA) of the enzyme, rather than simply blocking the enzyme's activity. In a series of experiments, conventional anti-Alzheimer's Disease drugs, as well as the novel drug EN101, were injected into mice with brain i...Kidney transplant patients face higher cancer risk

Patients taking immunosuppressants after organ transplantation would be assumed to be at higher risk for cancers. Studies show that this holds true for nonmelanoma skin cancers but do not agree for melanoma...Duke engineers developing ultrasound devices combining 3-D imaging with therapeutic heating

That current technique employs radio waves emitted from the end of an electrode probe that touches and excessively heats tissue selected for destruction. After threading that int...Contradictory immune responses explain different therapeutic effects in rheumatoid arthritis

... is a so-called crosslink breaker, responsible for destroying the rigid chemical bonds known as advanced glycation endproducts, or AGE for short, that form between body proteins and sugars over time. According to Zieman, both stiffening and reduced capacity of the arteries to expand in response to stress are c...How do islet cells die during early stages of diabetes?
... the body's own immune system starts attacking and destroying the insulin-producing islet cells in the pancreas. Once the majority of islet cells are destroyed, patients can no longer produce insulin to regulate their blood sugar and depend on strict diets and insulin injections.
