Scratch no more: Gene for itch sensation discovered

...in the itch sensation," Chen says. "So we began to systematically investigate this possibility." They studied scratching behavior in two sets of mice — normal mice and GRPR knockout mice. Normal mice scratched vigorously when exposed to a variety of itch-producing substances, but the knockout mice scratched much l...

Massive herds of animals found to still exist in Southern Sudan

...y time, the team used a survey technique of flying systematically along transects making observations of all wildlife, livestock, human activities and habitat. Observers on each side of the aircraft counted animals that they observed between two sets of rods placed on the wings of the plane. Using statistical techn...

Turn-ons and turn-offs for neurons

... for Medical Research in Heidelberg have therefore systematically examined individual components of the Tet systems and delineated the necessary conditions for reversible control of gene expression in neurons. In the June 20th issue of the online, open-access journal PLoS ONE, they report that genes which had be...

UCI scientists reconstruct migration of avian flu virus

...ains by location, the UCI analysis is the first to systematically track the migration of H5N1 through its evolutionary history, adding new details that identify the relative importance of the geographic and evolutionary advances the virus makes. From 192 samples obtained across Eurasia, the UCI team reconstructe...

Newborn brains grow vision and movement regions first

...anding that," he said. The study is the first to systematically obtain very high resolution magnetic resonance imaging (MRI) scans on a large group of newborns. The results appear in the Feb. 7 issue of the Journal of Neuroscience. Funding was provided by the National Institute of Mental Health and the UNC School...

Migration played key role in HIV spread in South Africa

...icut Healthcare System. Tetrault and colleagues systematically reviewed articles from 1966 through 2005 identified from the MEDLINE, PsychINFO and EMBASE databases that evaluated the effect of marijuana smoking on pulmonary function and respiratory complications.

Long-term marijuana smoking leads to respiratory complaints

Tetrault and colleagues systematically reviewed articles from 1966 through 2005 identified from the MEDLINE, PsychINFO and EMBASE databases that evaluated the effect of marijuana smoking on pulmonary function and respiratory complications. Of the 34 articles that met selection criteria, 1...

Researchers create artificial enzyme that mimics the body's internal engine

...continuous electron supply problem, the scientists systematically removed each of the three active centers-phenol, iron and copper-one at a time, as if the enzyme had been damaged and a specific active center was missing. "We found that great damage occurred, and that partially reduced oxygen species were produced ...

Twin studies reveal genetic components leading to cardiac and kidney disease

...he said. The researchers hope to more densely and systematically evaluate genotypes by studying blood samples from more twin pairs, in order to more extensively map genetic components that lead to increased risk of disease. CRP and Heart Disease For example, by studying twins, O’Connor’s team has identifie...

Protein found to shield pancreatic cancer cells from self-destruction

...agy, is a normal biological defense mechanism that systematically destroys defective cells by forcing them to kill themselves. In apoptosis, the cells die via damage to their nucleus and DNA, with other cellular organelles preserved. Autophagy kills by degrading those other organelles while sparing the nucleus. ...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

... results. "A deterministic global search algorithm systematically explores the parameter space, finding good values," Watson said. "Then the local search algorithm improves the values from the starting points found by the global algorithm." The parallel computer programs can now be used by others for similar pro...

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide

...blic Health and the Mount Sinai School of Medicine systematically examined publicly available data on chemical toxicity in order to identify the industrial chemicals that are the most likely to damage the developing brain. The researchers found that 202 industrial chemicals have the capacity to damage the human...

NYU biologists identify gene that coordinates two cellular processes

...ogists can draw connections between genes based on systematically accumulated experimental evidence. Network diagrams that illustrate such connections show that most genes fall into highly interconnected groups called modules. These modules are often enriched for genes that share the same role. In order to determin...

Taking 'chips' to the next level of gene hunting

...can contain disease-causing mutations and is often systematically ignored," he says. Boeke and his team have focused particularly on transposable elements, segments of DNA that hop around from chromosome to chromosome. These elements can, depending on where they land, wrongly turn on or off nearby genes, interru...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...medicine, "there has been no attempt to understand systematically how regenerative medicine could contribute to improving health in developing countries," the authors say. Building Capacity in Developing Countries for Regenerative Medicine While developed countries share large interests in treatments for such...

Fighting like a girl or boy determined by gene in fruit flies

...on to record each move and countermove. "Ed has systematically developed reproducibly aggressive behavior in flies and paved the way for serious analysis," said Laurie Tompkins, program director at the National Institute of General Medical Sciences, which funds the work. The fruit fly aggression model is part of...

Buildup of damaged DNA in cells drives aging

...of muscle mass and bone density, the investigators systematically compared the gene expression pattern of their progeroid mice to normal old mice to look for other similarities. What they found was a striking similarity pattern between the progeroid and normal-aged mice in several key pathways. Indeed, for genes...

Jefferson scientists find aging gene also protects against prostate cancer development

...ocks receptor activity, halting cancer growth. “We systematically tested each androgen receptor mutation,?Dr. Pestell explains. “These mutant receptors are resistant to current therapies and are all blocked by expression of SIRT1,?adding that prostate specific antigen (PSA) levels were used to confirm this. Rising ...
