Washington, Nov 12: Cambridge scientists have made a major breakthrough in rheumatoid arthritis. They have genetically engineered a drug-inducible form of Foxp3 gene, which when activated can prevent the autoimmune reaction characterised by the disease.

Rheumatoid arthritis is a painful, inflammatory type of arthritis that occurs when the body''s immune system attacks itself.

And the new strategy developed by scientists at the Medical Research Council''s Laboratory of Molecular Biology in Cambridge, may open the door for therapy development for rheumatoid arthritis.

Generally, immune cells develop to recognise foreign material – antigens; including bacteria - so that they can activate a response against them.

Washington, Nov 12: Scientists suggest that neuroprosthetic brain implants may help stroke patients to overcome partial paralysis.

The researchers from Washington University School of Medicine in St. Louis discovered that implants known as brain-computer interfaces (BCI) may be able to detect activity on one side of the brain that is linked to hand and arm movements on the same side of the body.

They hope to use these signals to guide motorized assistance mechanisms that restore mobility in partially paralyzed limbs.

Washington, November 12 : Testing cardiac patients for depression does not prove beneficial, reveals a new study.

Washington, Nov 12: Cell phone text messaging could be used to reduce kids'' chances of becoming fat later in life, by helping them monitor and modify their own behaviors now, a new study has suggested.

The study from the University of North Carolina at Chapel Hill suggests that self-monitoring of calorie intake is important for the long-term success of weight loss and weight control.

"Self-monitoring of calorie intake and expenditure and of body weight is extremely important for the long-term success of weight loss and weight control," said Jennifer R. Shapiro, Ph. D., assistant professor of psychiatry in the UNC School of Medicine and principal investigator of the new study, which is published in the November/December
