Wisconsin researchers identify sleep gene
Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep. In its normal state, the Drosophila (fruit fly) gene, called Shaker, produces an ion channel that controls the flow of potassium into cells, a process that cr...Brain-mapping technique aids understanding of sleep, wakefulness
The power of a new technique to map connections among nerve cells in the brain has a UT Southwestern Medical Center scientist dreaming of solving the mysteries of sleep. By tracking which nerve cells in the mouse brain stimulate others, researchers in Japan and at UT Southwestern found that a type of neuron responsible for keeping animals awake receives inhibitory signals from neurons act...Newly discovered protein an important tool for sleeping sickness research
Sixty million people in 36 countries of sub-Saharan Africa are threatened daily by a deadly parasitic disease known as African sleeping sickness. The disease is caused by organisms called trypanosomes, which are spread by the tsetse fly. African sleeping sickness affects approximately 500,000 people in sub-Saharan Africa, a quarter of whom will die this year. Because the trypanosome has an except...Researchers Identify Cause of Early Bird Sleep Disorder
A few rare people who consistently nod off early, then wake up wide-eyed much before dawn, can blame a newly-found mutant gene for their sleep troubles, Howard Hughes Medical Institute researchers announced today. This odd "time-shift" trait -- called familial advanced sleep phase syndrome (FASPS) -- was studied in one affected family by neurologist Louis J. Ptacek, a Howard Hughes Medical...Sleeping Sickness Epidemic Spreading in Uganda
A drug first used to reduce the risk of stomach ulcers in people taking certain types of painkillers offers an alternative to surgery after miscarriage, according to a study by researchers at the National Institute of Child Health and Human Development of the National Institutes of Health and other research institutions. The study appears in the August 18, 2005, New England Journal of Med...A week in UW research: fusion, racing and sleep
Put a GPS monitor on a bicycle, add devices that measure the riders heart rate and t...Good sleep enhances task performance
Sleep deprivations has been used to test the importance of sleep for memory and learning. It is difficult to interpret because of side effects, such as fatigue and reduced alertness. A study conducted on sleep-deprived patients by circumventing these complications by allowing recovery sleep by Harvard Medical school researches. Subjects who were sleep deprived on the first day showed no...Individuals with sleep related breathing disorders more prone to heart disease
A good night’s sleep is a gift, exclusive to the blessed. The less fortunate are those with sleeping disorders, who may experience problems such as early morning headaches or serious daytime fatigue. Among the various sleep disorders, sleep apnea in its mild or moderate form is commonly experienced. Sleep apnea is a disorder characterized by brief interruptions of breathing during sleep. Most ind...Sleep apnoea increases post-operative risks
People with sleep apnoea (shortness of breath) experience a greater risk of complications after elective knee or hip replacement. In sleep apnoea - which is most common in obese people - the muscles of the back of the throat relax during sleep and so obstruct the airways. The person stops breathing, momentarily, many times during the night and levels of oxygen in the blood fall.// Res...Sleeping sickness - a silent killer
Scientists from around the world are gathering in the West African state of Burkina Faso to tackle a disease believed to claim 1,00,000 African lives every year. Popularly known as Sleeping Sickness, and officially as 'African Trypanosomiasis', the disease is carried by the Tsetse fly. Some 60 million people living in Tsetse fly-endemic areas of west and central Africa are at risk, as are cattle...Data Presented at SLEEP 2007 Shows VEC-162 Improves Sleep Onset and Maintenance vs. Placebo
