Cocaine high caused by interference in neuronal receiving stations

... the activation of glutamate-responsive neurons by affecting a specific component, or subunit, of the receptor, called NR2B. Further experiments revealed that when rats were given cocaine, a specific subunit of dopamine receptors, called D2R, tended to attach to the NR2B subunit and was responsible for preve...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

... for Burkitt's lymphoma, an often-fatal malignancy affecting thousands of African children annually. It is also causally associated with at least four other kinds of human cancers, including Hodgkin's lymphomas, lymphomas in AIDS patients and organ transplant recipients as well as nasopharyngeal carcinomas. T...

New technology to speed up research into Huntington's disease

... CJD. Huntington's disease is a genetic disease affecting around 8 in 100,000 people. It is characterised by a progressive decline in cognitive functioning (including memory loss, intellectual decline and disorientation) together with the appearance of abnormal movements and impaired motor skills (such as u...

New dyslexia theory blames 'noise'

... to a deeper problem - not just a visual deficit - affecting all areas of perception. Sperling said people with dyslexia appear to have shaky mental categories for the essential sounds that make up language. "It's harder to make a [language] task automatic when your categories are fuzzier than they ou...

New HIV statistics indicate increasing toll of AIDS on African American community

... of a web of interconnected socioeconomic problems affecting the black community, such as residential segregation, school failure for children and a lack of access to health care, including HIV prevention, diagnosis and treatment services. Stabilizing black communities by expanding federal housing programs, s...

Human stem cells delay start of Lou Gehrig's disease in rats

.... "We only injected cells in the lower spine, affecting only the nerves and muscles below the waist," he noted. "The nerves and muscles above the waist, especially those in the chest responsible for breathing, were not helped by these transplanted stem cells." The research team used so-called SOD-1 ra...

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...effect, but the larger picture is that dioxins are affecting the normal growth and development of the reproductive system. Moreover, several effective treatments are available for BPH and thus reduction of BPH by a toxic compound is not a desirable effect." The study was based on data from the Air Force Hea...

Therapeutic role found for carbon monoxide

...death of the smooth muscle cells without adversely affecting the viability of the endothelial cells. "We discovered that endothelial cells must be present ?and be able to generate NO via nitric oxide synthase [NOS3] -- in order for CO to induce the death of the smooth muscle cells and reverse the symptoms of...

Changing length of days reverses how estrogen affects aggressiveness in mice

Zinc plays important role in brain circuitry

...ayer: zinc. By engineering a mouse with a mutation affecting a neuronal zinc target, researchers have demonstrated a central role for zinc in modulating signaling among the neurons. Significantly, they found the mutant mouse shows the same exaggerated response to noise as children with the genetic disorder cal...

Wheat gene may boost foods' nutrient content

...ly offering a solution to nutritional deficiencies affecting hundreds of millions of children around the world. Results from the study will be reported in the Nov. 24 issue of the journal Science. "Wheat is one of the world's major crops, providing approximately one-fifth of all calories consumed by humans,...

Wolves are suffering less from inbreeding than expected

...l PLoS ONE now demonstrates that inbreeding is not affecting the wolves as badly as expected. The results show that it is the most genetically variable wolf individuals that are recruited into the breeding population. An important consequence of this action of natural selection is that the negative effects of ...

International team analyzes human genetic variation in key immune region
