Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system — the biological cycles that repeat approximately every 24 hours — requires daily light exposure to the eye's retina to remain synchronized with the solar day. In a new study published in the June issue of Neuroscience Letters, researchers have demonstrated that when it comes to the circadian system, not all light exposure is created equal.

Lugano, Switzerland June 7, 2008 The Cancer and Leukemia Group B (CALGB) today announced data from a phase II clinical trial showing that 70 percent of patients with previously untreated follicular lymphoma responded to treatment with galiximab, an investigational anti-CD80 monoclonal antibody, when given in combination with rituximab. Of the 61 patients in the study, 44 percent achieved a complete response and 26 percent had a partial response. The data were presented at the 10th International Conference on Malignant Lymphoma (ICML).
SAN FRANCISCO, June 6 Gaining body fat may be a good thing, at least for people with type 1 diabetes, say researchers at the University of Pittsburgh Graduate School of Public Health. Their study, being presented at the 68th Scientific Sessions of the American Diabetes Association in San Francisco, followed 655 patients with type 1 diabetes for 20 years and found that patients who gained weight over time were less likely to die.
ST. LOUIS Patients with advanced heart failure may be receiving implantable cardiac devices that do not help them because they are too ill to benefit from the treatment, a Saint Louis University study found.
"Implantable cardiac devices were not intended for, or studied as 'rescue therapy' for very ill hospitalized patients with heart failure," said Paul Hauptman, M.D., professor of internal medicine at Saint Louis University School of Medicine and senior study author of the study.
Waltham, MA—As they struggle to contain skyrocketing medication costs, health plans across the U.S. have responded by implementing multi-tiered formularies requiring higher copayments for 'non-preferred' medications. New research from Brandeis University published in the Journal of Mental Health Policy and Economics suggests that the prevalent multi-tiered formulary system does impact how patients fill anti-depressant prescriptions, even though antidepressants have certain characteristics that can make it difficult for patients to switch medications.
BOZEMAN, Mont. -- Scientists who dig dinosaurs in Eastern Montana will now be able to chemically analyze fossils the same day they're excavated and before degrading begins.
Paleontologists from Montana State University, North Carolina State University and the North Carolina Museum of Natural Sciences recently bought and renovated a mobile laboratory that Dan Redding of Rudyard drove to Eastern Montana for the summer.
Brazil is in the midst of a transition from imitator to innovator in health-related products, according to the most comprehensive analysis to date of barriers and opportunities facing that country's health biotech industry.
BIRMINGHAM, Ala. -- Resistant hypertension, blood pressure that remains above goal despite taking three antihypertensive medications or high blood pressure that is controlled but requires four or more medications to do so, may benefit from specialized diagnostic and therapeutic treatment by health care providers according to guidelines issued by the American Heart Association and co-authored by UAB physicians.
BIRMINGHAM, Ala. A simple variation in a surgical technique developed at the University of Alabama at Birmingham (UAB) to reduce acute and chronic pain following lung surgery further reduces pain and helps return patients to normal activity quicker than the previous technique, according to a study published in the June issue of the Annals of Thoracic Surgery.
