Treating brain tumors with whole brain radiation therapy can damage healthy brain tissue, but a new study in mice reveals that limiting the oxygen supply, or hypoxia, can alleviate some of the cognitive impairment caused by the radiation. The results are reported in the Jan. 18 issue of the online journal PLoS ONE. http://medicalxpress.com/news/2012-01-radiation-induced-brain-tissue-reversed-oxygen.html Other Wed, 18 Jan 2012 17:25:18 EST news246129911 People with obstructive sleep apnea are more likely to stick to prescribed treatment when a partner or parent is involved with their treatment, according to a team of sleep researchers. http://medicalxpress.com/news/2011-12-approaches-apnea-benefit-cpap.html Sleep apnea Thu, 01 Dec 2011 16:20:01 EST news241977362 The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths.

CHD is responsible for more deaths in the first year of life than any other birth defect, but often outcomes can be improved with early detection. http://medicalxpress.com/news/2011-08-screen-newborns-heart-problems.html Cardiology Mon, 22 Aug 2011 04:12:32 EST news233205109 Researchers led by Montana State University have found a surprising condition that occurs in the lungs after an invasion of a common mold that can cause deadly infections in humans. http://medicalxpress.com/news/2011-08-results-lung-mold.html Medical research Thu, 04 Aug 2011 04:22:43 EST news231650544 Measuring oxygen during eye surgery, investigators at Washington University School of Medicine in St. Louis have discovered a reason that may explain why African-Americans have a higher risk of glaucoma than Caucasians. http://medicalxpress.com/news/2011-07-oxygen-eyes-african-americans-glaucoma.html Diseases, Conditions, Syndromes Mon, 11 Jul 2011 17:39:50 EST news229624741 (Medical Xpress) -- Continuing sleepless nights can increase the risk of heart disease, stroke and even death for sufferers of Obstructive Sleep Apnoea (OSA) who regularly stop breathing during the night for brief periods of time. http://medicalxpress.com/news/2011-06-high-sugar-fat-diet-cell.html Medical research Fri, 24 Jun 2011 08:55:34 EST news228124447 Cells grow abundant when oxygen is available, and generally stop when it is scarce. Although this seems straightforward, no direct link ever has been established between the cellular machinery that senses oxygen and that which controls cell division. Now, in the June 10 issue of Molecular Cell, researchers at Johns Hopkins report that the MCM proteins, which promote cell division, also directly control the oxygen-sensing HIF-1 protein. http://medicalxpress.com/news/2011-06-link-cell-division-oxygen.html Medical research Sat, 11 Jun 2011 03:46:39 EST news226982766 (Medical Xpress) -- A new computer screening tool developed and patented by a University at Buffalo physician is helping to detect severe obstructive sleep apnea in cardiovascular patients who have not yet been diagnosed with this common and potentially dangerous condition. http://medicalxpress.com/news/2011-06-screens-heart-disease-patients-severe.html Sleep apnea Tue, 07 Jun 2011 12:12:07 EST news226667493 A new study links the intermittent interruption of breathing that occurs in patients with obstructive sleep apnea (OSA) to enhanced proliferation of melanoma cancer cells and increased tumor growth in mice, according to researchers in Spain. The study also found tumor cells of OSA mouse models tended to contain more dead cells, indicating a more aggressive type of cancer. http://medicalxpress.com/news/2011-05-obstructive-apnea-linked-cancer-growth.html Sleep apnea Tue, 17 May 2011 14:03:24 EST news224859783
