Sickle-shaped red blood cells target and destroy tumor cells and blood vessels The genetic mutation that causes sickle cell anemia also turns red blood cells into potent tumor killers and may offer a new way to treat some cancers that are resistant to existing treatments, according to research published January 9 in the open access journal PLOS ONE by David S. Terman of Jenomic Research Institute and colleagues from Duke University and other institutions. The mutation that causes sickle...

COLLEGE STATION, Texas, Aug. 23, 2012 /PRNewswire-USNewswire/ -- The worst drought to hit the United States in at least 50 years does have one benefit: it has created the smallest "dead zone" in the Gulf of Mexico in years, says a Texas A&M University researcher who has just returned from gulf waters. (Logo: http://photos.prnewswire.com/prnh/20120502/DC99584LOGO) Oceanography professor Steve DiMarco, one of the world's leading authorities on the dead zone, says he and other Texas...

redOrbit Staff & Wire Reports - Your Universe Online A study published online in Nature Genetics provides important insights into understanding mammal variance and adaptation at high altitude. Researchers, led by Lanzhou University and joined by BGI Shenzhen, Institute of Kunming Zoology, Chinese Academy of Sciences as well as the other 12 institutes, have finished the genomic sequence and testing of a female domestic yak. As a symbol of Tibet and of high altitude, the yak (Bos...

By: Erika Dunayer, Ivanhoe Health Correspondent (Ivanhoe Newswire) -- Tossing and turning all night? Waking up yawning and feeling like a zombie? 18 million Americans who suffer from sleep apnea can relate. Now, two new studies are attempting to prove the condition leaving you weary could also cause cancer. Sleep apnea is an interruption of breathing while you sleep. There are different levels of severity within this disorder. Sleep apnea is such a prevalent issue today because...

While previous studies have associated SDB with increased risks of hypertension, cardiovascular disease, depression, and early death, this is the first human study to link apnea with higher rate of cancer mortality. Lead author Dr. F. Javier Nieto, chair of the department of population health sciences at the UW School of Medicine and Public Health, says the study showed a nearly five times higher incidence of cancer deaths in patients with severe SDB compared to those without the disorder, a...

New study finds exercise in low oxygen environment may result in improved insulin sensitivity Intermittent exercise with and without low oxygen concentrations (or hypoxia) can improve insulin sensitivity in type 2 diabetics, however exercise while under hypoxic conditions provides greater improvements in glycemic control than intermittent exercise alone, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism...

A new family of proteins which regulate the human body´s ℠hypoxic response´ to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and The University of Nottingham. The discovery has been published in the international journal Nature Cell Biology. It marks a significant step towards understanding the complex processes involved in the hypoxic response which, when it malfunctions, can cause and affect the...

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. The researchers, led by William Sonntag of University of Oklahoma, exposed the mice to a clinically relevant regimen of radiation, which caused progressive deterioration of...

Reducing a protein called Siah2 in mice improves mitochondrial response to low oxygen, a condition cells experience when blood flow is restricted during a heart attack 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...
