Scientists pinpoint inflammation gene

...the cells by clearing out the bad proteins tend to suffer higher levels of inflammation than people in whom the gene fulfills that role more efficiently, according to the study. The study found the same relationship between SEPS1 and inflammation in two geographically and ethnically distinct populations o...

Why Christmas trees are not extinct

Conifers such as Christmas trees suffer a severe plumbing problem. The "pipes" that carry water through firs, pines and other conifers are 10 times shorter than those in flowering trees. But a University of Utah study suggests why conifers not only survive but thrive: efficient microscopic...

Researchers identify molecular anchor that allows bacterial invasion of central nervous system

...e up to 25 percent of affected children may die or suffer permanent cognitive deficits, cerebral palsy, blindness, deafness or seizures. Therefore, an early acting treatment would help reduce the high rates of disability and death. "Previous studies have found that Streptococcus bacteria from infants with ...

Building a better mouse model of lung cancer: FHIT counts

...estingly, humans whose VHL gene is lost or mutated suffer from a condition called Von-Hippel Lindau disease, an inherited disorder characterized by abnormal blood vessel growth in the eyes, brain, spinal cord, adrenal gland and other parts of the body. The scientists exposed mice deficient in both genes to...

New factor implicated in allergy and asthma attacks

...eath -- symptoms agonizingly familiar to those who suffer from allergy and asthma attacks. Scientists have long assumed that they know how pollen produces such debilitating responses. They blame an overreaction by the body's immune system, set off by proteins known as antigens, which are found on the surfa...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...ike. That's why patients often lose their hair and suffer numerous other side effects. For us, the Holy Grail would be finding a way to selectively kill cancer cells and not damage healthy ones." Nanotechnology For the PNAS experiment, Dai and his colleagues used a basic tool of nanotechnology--carbon nan...

Amphetamines reverse Parkinson's disease symptoms in mice

...id. In the United States, at least 500,000 people suffer from Parkinson's disease, and about 50,000 new cases are reported annually, according to the National Institute of Neurological Disorders and Stroke. These figures are expected to rise as the average age of the population increases. Symptoms of the d...

Researcher says flu responders can learn from 1918 epidemic

...de some hope that 21st century Americans might not suffer the fate of their forebears, but Higgins said that survival might depend on the simple concept of community planning. In studying the metropolitan areas around the state of Pennsylvania, Higgins found that the areas that suffered the lowest mortalit...

Costly breeding programs for endangered species pay off

...I populations were less likely to go extinct or to suffer population crashes than were the populations that had undergone limited inbreeding. "The benefits of maximum-avoidance inbreeding were difficult to detect as long as the populations remained captive," said Meffert. "It's not clear why this is the ca...

Fluoride poisoning in China due to clay, not coal

Millions of people in southwest China suffer from potentially-crippling fluoride poisoning because they burn a mixture of clay and coal, say researchers. The findings, from a study carried out in Guizhou province, contradict the previous belief that the disease was caused by people burning flu...

Scientists use gene transfer technology and common virus to block neuropathic pain

...with neuropathic pain," Fink says. "These patients suffer tremendously and the treatments available to us now have limited effectiveness. Using our herpes vector to provide targeted gene delivery to the nervous system is a novel approach that shows tremendous promise for the treatment of neuropathic pain." ...

Acid water in East Java threatens biodiversity and local welfare

...a, which with its enormous water surface would not suffer any detrimental effects due to this small quantity of acidic water. Lohr wants to hold discussions with local authorities, other researchers and companies in order to arrange such a diversion or another solution. The biologist recently received a dis...

Gradient guides nerve growth down spinal cord

.... An estimated 250,000 people in the United States suffer from permanent spinal cord injuries, with about 11,000 new cases each year. This study focused on corticospinal neurons, which control voluntary movements and fine-motor skills. These are some of the longest cells in the body. The corticospinal neur...
