(Medical Xpress)—The cochlear implant is widely considered to be the most successful neural prosthetic on the market. The implant, which helps deaf individuals perceive sound, translates auditory information into electrical signals that go directly to the brain, bypassing cells that don't serve this function as they should because they are damaged. http://medicalxpress.com/news/2013-04-device-resolution-deaf-individuals-opt.html Medical research Fri, 05 Apr 2013 06:25:01 EST news284361856 University of Pittsburgh Cancer Institute (UPCI) researchers have uncovered a technique to halt the growth of cancer cells, a discovery that led them to a potential new anti-cancer therapy. http://medicalxpress.com/news/2013-02-reveal-mechanism-halt-cancer-cell.html Cancer Mon, 04 Feb 2013 04:30:27 EST news279174611 More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA—within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases. http://medicalxpress.com/news/2013-01-scientists-one-step-gene-mitochondrial-diseases.html Medical research Tue, 29 Jan 2013 11:00:17 EST news278679551 University of Texas Medical Branch at Galveston researchers have discovered that the commonly used antidepressant drug paroxetine could also become a therapy for the vascular complications of diabetes. http://medicalxpress.com/news/2012-12-antidepressant-duty-diabetes-drug.html Diabetes Fri, 14 Dec 2012 09:55:11 EST news274701291 Mitochondria, tiny structures within each cell that regulate metabolism and energy use, may be a promising new target for cancer therapy, according to a new study. Manipulation of two biochemical signals that regulate the numbers of mitochondria in cells could shrink human lung cancers transplanted into mice, a team of Chicago researchers report in the journal FASEB. http://medicalxpress.com/news/2012-02-energy-network-cells-cancer-therapy.html Cancer Tue, 21 Feb 2012 11:00:01 EST news249043340 Mitochondria are often called cellular "powerhouses" because they convert nutrients into energy. But these tiny structures also help determine cellular lifespan. Scientists at Sanford-Burnham Medical Research Institute (Sanford-Burnham) are now discovering how mitochondria alternate between duplicating and fragmenting and how these events help cells adapt to diverse physiological conditions. http://medicalxpress.com/news/2011-11-mitochondria-protein-therapeutic-heart-disease.html Cardiology Thu, 17 Nov 2011 14:47:06 EST news240763601 The kidney performs several vital functions. It filters blood, removes waste products from the body, balances the body's fluids, and releases hormones that regulate blood pressure. A number of diseases and conditions can damage the kidney's filtration apparatus, such as diabetes and immune disorders. This damage leads to a condition called nephrotic syndrome, which is characterized by protein in the urine, high cholesterol and triglycerides, and swelling (edema). People with nephrotic syndrome retain salt and water in their bodies and develop swelling and high blood pressure as a result. http://medicalxpress.com/news/2011-09-kidney-high-blood-pressure.html Diseases, Conditions, Syndromes Thu, 22 Sep 2011 12:44:14 EST news235914218
