"This funding not only stimulates the research of existing faculty but also should make the university more competitive in attracting the best faculty and students in biomedical fields so vital to all areas of health-related research." Reinhold can already see the effects of the gra...

OSU studies breast cancer risk and beef consumption

...atory studies suggest that zeranol, like estrogen, stimulates estrogen-modulated genes that can affect the growth of human breast cancer cells. "We think this may be important, because some studies suggest that the more unopposed estrogen a woman is exposed to over her lifetime, the greater her chances of deve...

The role of obesity and calories in cancer prevention

...e appears to be a point above which calorie intake stimulates the growth of breast cancer and can potentially override, to some degree, the protective effect of severe caloric restriction." Mammary mouse tumor virus (MMTV)TGF mice (TGF regulates growth) were fed either an ad lititum (as desired; AL), a calorie ...

The unknown "trigger" molecule is likely to be some kind of nutrient essential to growth, making PAS kinase another important sensor of a cell's metabolism, according to Rutter. Rutter said that he was "completely shocked" by the...

Secretary Abraham announces next steps for artificial retina project

...itted to the electrode array in the eye. The array stimulates optical nerves, which then carry a signal to the brain. The prototype implants contain 16 electrodes, allowing patients to detect the presence or absence of light. The artificial retina project's "next generation" device would have 1,000 electrodes...

Environmental enrichment reverses learning impairments caused by lead poisoning

Environmental enrichment that stimulates brain activity can reverse the long-term learning deficits caused by lead poisoning, according to a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. It has long been known that lead poisoning in children affects ...

Tailor-made sugar coated proteins manufactured in novel E. coli system

... Factor VIII and the hormone erythropoietin, which stimulates the production of red blood cells by stem cells in bone marrow. Both these proteins, which require the addition of sugar molecules to function properly, are currently produced by culturing mammalian cells, which can be a costly and technically diffic...

Combining global environmental changes yields surprising ecosystem response

... and the traditional view that elevated CO2 always stimulates plant growth simply isn't correct." The research is published in the December 6, 2002, issue of Science. Many past studies of global-change impacts on plants and ecosystems have focused on responses to increases in atmospheric CO2. But realistical...

Shifts in rice farming practices in China reduce greenhouse gas methane

That's because draining stimulates rice root development, and also accelerates decomposition of organic matter in the soil to produce more inorganic nitrogen, an important fertilizer. Methane is produced by soil microbes in paddy soils under anaerobic conditions, or in the absence of ...

In 1998, Jevtovic-Todorovic discovered that the drug nitrous oxide, or laughing gas, work by inhibiting the NMDA glutamate system. Another anesthetic drug known as Ketamine, a...

Obesity not a personal failing, but a battle against biology

...body fat decreases, less leptin is produced, which stimulates food intake and reduces energy expenditure. Research by Friedman and other scientists has shown that genetic mutations that lead to a full or partial loss of leptin are associated with obesity in some humans. In addition to leptin, Friedman and othe...
