Scientists are learning how to rescue oxygen-starved cells in humans who suffer a heart attack or stroke by studying microscopic worms that can survive with almost no oxygen. Washington University School of Medicine neurobiologists in St. Louis, MO, have identified pathways that allow microscopic worms to survive in a low-oxygen environment. Researchers say the finding could have implications for patients suffering from stroke, heart attack and cancer. "In stroke and heart attack, cells die...

SAN FRANCISCO, Oct. 15 /PRNewswire-USNewswire/ -- In a national study presented earlier today at the 2008 American College of Surgeons (ACS) Clinical Congress, a researcher reported that "women under 40 years of age diagnosed with Stage I breast cancer are 44 percent more likely to die than older women." According to Julie A. Margenthaler, MD, assistant professor of surgery, Washington University School of Medicine, St. Louis, MO, "These are women with similar size tumor and lymph node...

Staying fit may be more difficult for women than for their male counterparts.In a study conducted by researchers in the UK and the U.S., scientists found that women typically do not use protein as effectively as men to keep their muscle.Researchers studied 29 men and women aged 65 to 80. They found that women built up less muscle than the men after doing resistance exercise. People lose up to 0.4 percent of their muscle mass every year following their 50th birthday, which can make them more...

By Rodriguez, Fausto J Perry, Arie; Gutmann, David H; O'Neill, Brian Patrick; Leonard, Jeffrey; Bryant, Sandra; Giannini, Caterina Abstract There are few pathologic studies of gliomas in patients with neurofibromatosis type 1. We analyzed clinical and pathologic features of gliomas from 100 neurofibromatosis type 1 patients (57 men; 43 women). The median age at tumor diagnosis was 13 years (range, 4 months to 68 years). Most tumors were typical pilocytic astrocytoma (PA) (49%) or diffusely...

Oct. 19, 2005 -- An international team of researchers has partially untangled the genetic details of a mysterious disorder that formerly caused seizures and death in infant boys within a month of birth. The researchers discovered a rare change in the DNA of two eastern Missouri families with a history of a condition called X-linked recessive idiopathic hypoparathyroidism (XLHPT): a portion of the X chromosome, a human sex chromosome, has been removed and replaced by a copy of a much larger...

Aug. 11, 2005 -- You win some, you lose some. A protein that protects the body from tissue damage also increases the risk of tumors, according to a study conducted at Washington University School of Medicine in St. Louis. Moderate reduction of the protein level protects against tumor formation but increases susceptibility to tissue injury. Because of its protective function in the body, the protein potentially could be used to selectively shield cells from toxic therapies, according to...
