People who have multiple sclerosis (MS) for 10 years and have few of the disabling symptoms of the disease are often told they have “benign MS” and that their symptoms will likely not ever occur to the same extent as other people with MS.
Using a nuclear transfer procedure, scientists at Rockefeller University and the Howard Hughes Medical Institute have, for the first time, shown reproducibly that mice can be cloned from adult stem cells.
In a randomized placebo-controlled trial, patients smoking cannabis experienced a 34 percent reduction in intense foot pain associated with HIV — twice the rate experienced by patients who smoked placebo.
In a new large, prospective study, researchers found that midday napping — siestas — reduced coronary mortality by about one-third among men and women.
New research published in the February issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians (ACCP), suggests that high-risk smokers with acute cardiovascular disease are three to four times more likely to quit smoking when treated with an intensive smoking cessation program.
In patients with recently diagnosed multiple sclerosis, the extent of accumulated brain tissue loss and overall lesion load as determined by magnetic resonance imaging (MRI) may predict the rate of cerebral atrophy over the following two years, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals.
Among patients with retinal disease, molecular testing can confirm a clinical diagnosis of hereditary disorders, identify carrier status and confirm or rule out the presence of a familial mutation in those without symptoms, according to a report in the February issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Healthy and viable mice that survive until adulthood have, for the first time, been cloned from adult stem cells. Scientists from Rockefeller University, including Howard Hughes Medical Institute investigator Elaine Fuchs, used cells called keratinocyte stem cells, which represent a new model system for cloning. Keratinocytes come from the skin, making them a particularly attractive stem cell source because of their ready accessibility.
A powerful two-gene test distinguishes between a pair of nearly identical gastrointestinal cancers that require radically different courses of treatment, researchers report this week in the online Early Edition of the Proceedings of the National Academy of Sciences.
Exposure to second-hand smoke at work, home or elsewhere results in a disproportionate rise in markers that increase the risk of cardiovascular disease, University of Nottingham researchers have found.
