Conjunctivitis, commonly known as pinkeye, is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids. Although typically a mild, self-limiting disease in children and adults, newborns are particularly susceptible to pinkeye and can be more prone ...
This prediction comes from a Saint Louis University School of Medicine researcher who spent a year in China studying its geriatric policies and practices. Joseph H. Flaherty, M.D., associate professor of internal medicine in the division of geriatric medicine at Saint Louis University, said China’s 1979 policy of limiting couples ...
Breast cancer surgery patients often suffer side effects such as pain, nausea, and fatigue during and after their operation. These complications can lengthen their hospital stay, lead to hospital readmission, or require additional medications--all of which increase medical costs. Several previous studies have suggested that hypnosis may reduce pain, recovery ...
The Collaborative Cross, begun in 2005 with a grant from the Ellison Medical Foundation, represents a fundamentally new way of conducting genetics research and aims to create 1,000 strains of mice that feature the genetic diversity of the world population. When completed in about five years, the research community ...
Biological differences seen in individuals with PTSD, including low cortisol levels, could either result from exposure to a traumatic event or could be present before such an event and predispose patients to the condition, according to background information in the article. "Once identified, such risk factors may prove to be ...
In a study using human muscle tissue, scientists in Children’s Stem Cell Research Center - led by Johnny Huard, PhD, and Bruno Péault, PhD - isolated and characterized stem cells taken from blood vessels (known as myoendothelial cells) that are easily isolated using cell-sorting techniques, proliferate rapidly and can be ...
Most hormones and cytokines have a short life and therefore require frequent injections as therapy. However, the new technology developed by the multidisciplinary team at Sheffield, means that scientists and clinicians are able to generate effective, long-acting hormones which promote growth over a minimum of ten days, after just one ...
The study reveals that the gene, known as Disrupted-In-Schizophrenia 1 (DISC1), directs the incorporation of new neurons into the adult brain and keeps the process under control. The gene’s newly discovered roles might help to explain why schizophrenia’s symptoms generally arise in adolescence or early adulthood, the researchers suggested. The research ...
In a long-term study of 100,000 pregnant Norwegian women, the researchers saw an unexpected increase in new incidences of binge eating disorder that began during pregnancy. The research is the largest population-based study of eating disorders during pregnancy. Previously, small clinical studies had suggested that often eating disorders go into ...
"This is the first prospective study to report a significant association between alcohol and endometrial cancer," says Veronica Wendy Setiawan, assistant professor of preventive medicine at the Keck School of Medicine of USC. "Previous studies have shown that alcohol consumption has been associated with higher levels of estrogens in postmenopausal ...
This results in severe diarrhea and, in rare cases, death. Abraham "Linc" Sonenshein, PhD, and colleagues from the Department of Molecular Biology and Microbiology at the Tufts University School of Medicine (TUSM) and the Sackler School of Graduate Biomedical Sciences at Tufts, have discovered how a protein called CodY regulates ...

Given its potential impact on the treatment of diabetes, deciphering the molecular pathways that control beta-cell proliferation is an area of intensive investigation. In a new study, Anil Bhushan and colleagues from the David Geffen School of Medicine, Los Angeles, show that the protein Skp2 has a critical role in ...
Previous mouse research has shown that both oxidative stress and increased T cell activity contribute to bone loss following estrogen depletion, which occurs after menopause or when ovaries are removed. Oxidative stress is the toxic accumulation of too much reactive oxygen in cells. Research has shown that T ...
The study, to be published in the September issue of the Journal of General Internal Medicine, found that when HIV patients lead chaotic lives -- meaning they are disorganized or experience too many unexpected events -- that chaos can act as a barrier to regular medical care. The researchers ...
"Everything that itches isn’t a yeast infection," said Susan Hoffstetter, Ph.D., assistant professor of obstetrics, gynecology and women’s health at Saint Louis University School of Medicine and a SLUCare women’s health nurse practitioner. "People keep treating themselves. They buy over-the-counter medicines for yeast infections or they call the doctor to ...
High cholesterol which runs in families is known as familial hypercholesterolaemia. It affects about two in every 1000 people and causes very high levels of low density lipoprotein (LDL) or ’bad cholesterol’ in the blood. It carries a high risk of death from coronary heart disease. Treatment to lower cholesterol ...
