Scientists in Texas are reporting development of a first-of-its-kind cloth that releases nitric oxide gas — an advance toward making therapeutic socks for people with diabetes and a wrap to help preserve organs harvested for transplantation. The study is in ACS' Chemistry of Materials, a bi-weekly journal.

NEW ORLEANS – A study released by the Minerals Management Service today examines the circulation in the Eastern Gulf of Mexico (GOM) and sheds new light on the behavior of the Loop Current (LC) and Loop Current Eddies (LCEs), the relation between the upper- and lower-layer currents, and the variability of water mass characteristics in deepwater.
When the LC and the LCE are present in the Gulf near oil and gas activities, operators may have to curtail or amend their operations due to the strength of the current or eddy.
(Boston) - Clinicians rely on laboratory tests to monitor the progression or remission of disease, or to identify pathologic alterations in physiology that may precede clinical events. Monitoring quantitative laboratory results represents a crucial component in the assessment of response to therapy. Researchers at Boston University School of Medicine (BUSM) have developed a mathematical methodology to reduce the effect of biologic variation on the difference necessary to detect changes in clinical status.
Los Angeles, London, New Delhi, Singapore and Washington DC (Jan 6, 2010) – If you're one of the millions of headache sufferers around the world, more effective relief might be on the way in years to come. That's because the International Headache Society has just published new research guidelines intended to stimulate more research into headache treatment, and to provide researchers with guidelines to cut health risks associated with treatment.
Rheumatoid arthritis (RA) patients are partially protected by the influenza vaccine 6-10 months after treatment with rituximab. Researchers determined that while the flu vaccine is safe, it is ineffective for RA patients in the first 6 months following rituximab treatment. Previous influenza vaccination in rituximab-treated patients does increase pre- and post-vaccination titers, providing some defense to influenza strains. RA activity was not influenced by administration of the flu vaccine.
A new approach to solving the problem of school timetabling, known as a GRASP, has been developing by researchers in Brazil. They report details in a forthcoming issue of the International Journal of Operational Research.
It's time to set the record straight. The only reliable way to lose weight is to eat less or exercise more. Preferably both.
So why bother to state the obvious? Because a body of scientific literature has arisen over recent years, suggesting that fat oxidation – burning the fats we eat as opposed to the carbohydrates – is enough to promote fat loss. It isn't.
Washington, DC – Researchers at Georgetown Lombardi Comprehensive Cancer Center have found a way to cleverly override signals that tell breast cancer cells to keep surviving in the face of anticancer treatment. The investigational agent they used renews the sensitivity of these breast cancer cells to treatment by fulvestrant (Faslodex®) which had stopped working.
SALT LAKE CITY, Jan. 5, 2010 – Unlike Hawaii and other island groups, no native bird has gone extinct in the Galapagos Islands, although some are in danger. But University of Utah biologists found that finches – the birds Darwin studied – develop antibodies against two parasites that moved to the Galapagos, suggesting the birds can fight the alien invaders.
New UK research, published today in PLoS ONE, has not reproduced previous findings that suggested Chronic Fatigue Syndrome may be linked to a recently discovered virus. The authors of the study, from Imperial College London and King's College London, say this means that anti-retroviral drugs may not be an effective treatment for people with the illness.
PHOENIX, Ariz. — Jan. 5, 2010 — Circumcision, which substantially lowers HIV risk in men, also dramatically changes the bacterial communities of the penis, according to a study led by scientists at the Translational Genomics Research Institute (TGen) and Johns Hopkins University and published Jan. 6 in the scientific journal PLoS ONE.
And these bacterial changes may also be associated with earlier observations that women whose male partners are circumcised are less likely to develop bacterial vaginosis, an imbalance between good and harmful bacteria.
GAINESVILLE, Fla. — Scientists who compare insect chirps with ape calls may look like they are mixing aphids and orangutans, but researchers have found common denominators in the calls of hundreds of species of insects, birds, fish, frogs, lizards and mammals that can be predicted with simple mathematical models.
Current use of prenatal ultrasounds in women with singleton pregnancies is 55% greater than in 1996, even in low-risk pregnancies. More than one-third (37%) of pregnant women now receive 3 or more ultrasound tests in the second and third trimesters of a given pregnancy, found an article http://www.cmaj.ca/embargo/cmaj090979.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca.
Vitamin D deficiency may contribute to a higher number of heart and stroke-related deaths among black Americans compared to whites, according to a University of Rochester Medical Center study.
The journal Annals of Family Medicine is publishing the study in the January-February edition, which goes online Jan. 11, 2010.
There is no evidence to support psychological debriefing in schools after traumatic events such as violence, suicides and accidental death, which runs counter to current practice in some Canadian school jurisdictions, according to a commentary http://www.cmaj.ca/embargo/cmaj091621.pdf in CMAJ (Canadian Medical Association Journal) www.cmaj.ca .
