Brain scans of jazz musicians show language and music similarities

jazz musiciansWashington, Feb 24 : A new study has found that the brains of jazz musicians engrossed in spontaneous, improvisational musical conversation showed robust activation of brain areas traditionally associated with spoken language and syntax, which are used to interpret the structure of phrases and sentences.

But this musical conversation shut down brain areas linked to semantics- those that process the meaning of spoken language, the study found.

Ambivalent hearts may be at higher risk of heart diseases

Ambivalent hearts may be at higher risk of heart diseasesWashington, Feb 24 : A new study has found that if a couple feel ambivalent towards their partner they are at an elevated heart disease risk.

Key protein essential for malaria parasite transmission to mosquitoes found

malariaWashington, Feb 24 : Researchers have found that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite.

The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes-the only forms that are infectious to mosquitos.

Nanoparticles help deliver anti-inflammatory drugs to 'rogue' immune cells

anti inflammatory drugsWashington, Feb 24 : Researchers have developed a system which will help deliver anti-inflammatory drugs to immune cells that have gone out of control, while sparing their well-behaved counterparts.

The system uses nanoparticles made of tiny bits of protein designed to bind to unique receptors found only on neutrophils, a type of immune cell engaged in detrimental acute and chronic inflammatory responses.

Brain region essential for socializing identified

BrainWashington, Feb 24 : Researchers have determined that a small region of the hippocampus known as CA2 is essential for social memory, the ability of an animal to recognize another of the same species.

A better grasp of the function of CA2 could prove useful in understanding and treating disorders characterized by altered social behaviors, such as autism, schizophrenia, and bipolar disorder.

Recent studies have shown that different subregions of the hippocampus have different functions.

Women at higher risk of heart attacks than men

Women at higher risk of heart attacks than menWashington, Feb 23 - A new study has revealed that there are some significant differences between men's and women's hearts, and these differences may put women at a much higher risk for heart woes than their male counterparts.

Immune cell therapy may revolutionize leukemia treatment

Immune cell therapy may revolutionize leukemia treatmentWashington, Feb 23 - A team of researchers, who conducted largest ever study of patients with advanced leukemia, have found that 88 percent achieved complete remissions after being treated with genetically modified versions of their own immune cells, thus demonstrating that cell therapy is a powerful treatment for patients who have exhausted all conventional therapies.

Blood test might predict multiple sclerosis long before symptoms appear

Blood test might predict multiple sclerosis long before symptoms appearWashington, Feb 23 - A new study has revealed that an antibody found in the blood of people with multiple sclerosis (MS) may be present long before the onset of the disease and its symptoms.

"If our results can be replicated in larger populations, our findings may help to detect MS earlier in a subgroup of patients," study author Viola Biberacher, MD, with Technical University in Munich, Germany, said.

Those memory lapses could be Alzheimer's

Those memory lapses could be Alzheimer'sWashington, Feb 22 : If you think you are developing Alzheimer's, you could be right, warns a study.

The study suggests that self-reported memory complaints might predict clinical memory impairment later in life.

Obese women get only one hour of exercise per year

Obese womenWashington, Feb 22 : A new study suggests that obese women get an average of one hour of exercise annually.

Researchers analyzed data from a 2005-2006 government survey that included nearly 2,600 adults between ages 20 and 74. They studied participants' weight, diet and sleeping patterns, in addition to analyzing exercise levels as measured by an accelerometer.

Carbohydrates rich diet could up dementia risk

Washington, Feb 22 : Researchers have linked carbohydrate calorie-rich diets to a greater risk for brain shrinkage, dementia and Alzheimer's disease, impaired cognition, and other disorders.

Deadly human malaria parasite may have come out of Africa

malaria parasiteWashington, Feb 22 : Researchers have claimed to have linked origin of deadly human malaria parasite to primates to Africa, and not Asia, as once believed.

Until recently, the closest genetic relatives of human P. vivax were found only in Asian macaques, leading researchers to believe that P. vivax originated in Asia.

Selenium and vitamin E supplements can up prostate cancer risk

Vitamin E supplementsWashington, Feb 22 : Researchers have found that high-dose supplementation with both the trace element selenium and vitamin E increase the risk of high-grade prostate cancer.

These findings are based on data from the Selenium and Vitamin E Cancer Prevention Trial, or SELECT, a rigorously executed, randomized and placebo-controlled trial conducted by the SWOG cancer research cooperative group that involved more than 35,000 men.
