Washington, Apr 8 : Researchers from Oregon State University suggest a classroom-based intervention program that has been found to significantly reduce the amount of violent TV that children watch.

The study showed that special classroom curriculum could reduce violent TV viewing among first- through fourth-grade children by nearly 18 pct.

It could also reduce students'' identification with superheroes compared to children in a control group.

Washington, April 8 : A research team, including an Indian-origin boffin, has shed light on why people with diabetes have high blood glucose levels.

Researchers at Joslin Diabetes Center have shown for the first time that insulin plays a significant role in suppressing levels of glucagon, a hormone involved in carbohydrate metabolism and regulating blood glucose levels.

According to researchers, the new findings could lead to development of a drug aimed at targeting glucagon levels.

Washington, Apr 8 : An inflammatory factor-already implicated in causing several diseases, like pulmonary disease, lung cancer, and arthritis- may also have a role to play in insulin resistance linked with obesity, according to a study.

The researchers behind the study say that an inflammatory protein, known as CXCL5, rises and falls with obesity and subsequent weight loss in humans.

They say that they experiments on mice have provided further evidence linking the inflammatory factor, which is produced and secreted at high levels by fat tissue, to insulin resistance.

The researchers have also shown that treatments designed to block its action improve the animals'' sensitivity to insulin.

Washington, Apr 8 : Acupuncture may not help relieve menopause-related hot flushes, say researchers.

The conclusion of a systematic review of literature by three groups in Daejon, Busan (South Korea) and Exeter (UK) has been published in the current edition of the peer-reviewed journal Climacteric.

Many women are concerned by the unfavourable publicity given to HRT use, but still have to deal with the symptoms which can occur during and after the menopause. A significant minority of women look for alternatives to HRT to deal with these symptoms.

Washington, Apr 8 : Even in forests, sex sells. A new study has found that male chimpanzees that share meat with females double their chances of having sex with them.

The study led by researchers from the Max Planck Institute for Evolutionary Anthropology in Germany has been published in the open-access, peer-reviewed journal PLoS ONE April 8.

Washington, April 8 : Heart failure patients may slightly reduce their likelihood of death or hospitalisation by exercising regularly, without any safety risk.

This suggestion is based on a study supported by the National Heart, Lung, and Blood Institute (NHLBI), which was conducted at 82 centres in the U. S., Canada, and France.

It has shown that heart failure patients who add regular, moderate physical activity to standard medical therapy generally have a higher quality of life compared to patients who receive medical therapy only.
