Negative effects of sleep restriction may linger after 1 night of recovery sleep

(American Academy of Sleep Medicine) Neurobehavioral impairments such as delayed reaction times accumulated across a period of five days when sleep was restricted to less than four hours per night. Measures of alertness improved significantly after a night of recovery sleep, with larger doses of sleep producing greater gains. Yet some neurobehavioral deficits continued to linger after the maximum recovery dose of 10 hours in bed, during which participants slept for an average of about nine hours.

Purple light means go, ultraviolet light means stop

(University of Rochester) A new membrane developed at the University of Rochester's Laboratory for Laser Energetics blocks gas from flowing through it when one color of light is shined on its surface, and permits gas to flow through when another color of light is used. It is the first time that scientists have developed a membrane that can be controlled in this way by light.

Short and long sleep durations are independent risk factors for cardiovascular disease

(American Academy of Sleep Medicine) The risk of any cardiovascular disease for adults who reported sleeping five hours per day or less was more than two times higher than that of people who reported a daily sleep duration of seven hours (adjusted odds ratio = 2.20). Participants who reported sleeping nine hours or more per day also had an elevated risk of cardiovascular disease (adjusted OR = 1.57). Results were adjusted for potential confounders including smoking, diabetes, hypertension and depression.

SIDS surprise: Study finds that infant boys are more easily aroused from sleep than girls

(American Academy of Sleep Medicine) At 2 to 4 weeks of age, the mean strength of a pulsatile air-jet stimulus that was required to induce arousal during quiet sleep was significantly lower in male infants than female infants. At 2 to 3 months of age when the SIDS risk peaks, this gender difference in arousal threshold was no longer significant. Results suggest that there are no gender differences in arousability that could increase the vulnerability of male infants to SIDS.

First regional student food drive to fight hunger

High schools throughout Southeastern Pennsylvania are invited to join Shire's The Great Food Fight!, the first regional student food drive to fight hunger. The goal: to collect 25 tons of food - the equivalent of 50,000 meals - for Philabundance and the thousands of local families who rely on the food services they provide. Shire will present the school that collects the most food per student a grand prize of $10,000.

Research findings point to new ways to improve quality of future trials through better training

Practitioners of clinical medicine are familiar with learning curves, and strategies like simulation are increasingly used to minimize learning-curve effects on clinical care. Because similar learning curves have been hinted at in some clinical trials, researchers at Duke University Medical Center studied the phenomenon in the data record of a large, multi-site clinical trial. Their findings point to ways to improve the quality of future trials through better training and simulation exercises.

Red blood cells have a tiny but effective protector -- microRNA

(Children's Hospital of Philadelphia) Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress. The study illustrates how microRNA fine-tunes gene activity.

Nevirapine, an anti-retroviral that is being increasingly used, was implicated as the cause of VBDS in a patient described in a recent report.

New approach to Alzheimer's therapy

(Helmholtz Association of German Research Centres) Researchers from the German Centre for Neurodegenerative Diseases and the Ludwig-Maximilians-Universitat in Munich have shown that the ADAM10 protein can inhibit the formation of beta-amyloid, which is responsible for Alzheimer's disease. ADAM10 acts like a pair of molecular scissors to cut the protein from which beta-amyloid is formed, effectively preventing the formation of beta-amyloid. This makes ADAM10 a key molecule in Alzheimer's therapy.

A breakthrough in tuberculosis research

(McGill University) The key to the fate of the macrophages is the balance between two kinds of eicosanoids. Eicosanoids are molecules that contribute to the control of our immune system. The genetic code of TB bacteria enables it to tip this balance in favor of necrosis, and human genetic analysis revealed that modification in eicosanoids production is associated with susceptibility or resistance to TB. Fortunately, drugs that target the production of eicosanoids are already in use for treating other inflammatory diseases, such as rheumatoid arthritis.

The study concludes that coughing or other respiratory symptoms are more accurate in determining influenza infection than presence of a fever.

Mechanism uncovered behind Salmonella virulence and drug susceptibility

(University of Washington) Researchers have discovered a novel mechanism in Salmonella that affects is virulence and its susceptibility to antibiotics. The mechanism changes the bacteria's production of proteins in a previously unheard of manner. It allows Salmonella to selectively change its levels of certain proteins to respond to inhospital conditions. Although the mechanism had not been recognized before, scientists found evidence of a similar mechanism in all five kingdoms of life. The mechanism appears to have been conserved throughout the course of evolution.
