Nontoxic drug halts and reverses rheumatoid arthritis

A researcher from Northwestern University Feinberg School of Medicine has invented a novel way to halt and even reverse rheumatoid arthritis. He developed an imitation of a suicide molecule that floats undetected into overactive immune cells responsible for the disease.

DNA variations in genes increase risk of developing PI-IBS

Studies of the victims of the Walkerton, Ont. tainted drinking water tragedy have led researchers to discover DNA variations in genes that increase the risk of developing post-infectious irritable bowel syndrome (PI-IBS). The sheer scale of infection and the recording of the health of Walkerton's citizens gave a team of researchers a unique opportunity to study the origin of this disorder.

Blocking action of key protein boosts immune 'memory' to prevent or clear viral infection

Researchers at The Scripps Research Institute have discovered a potential new way to stimulate the immune system to prevent or clear a viral infection. By blocking the action of a key protein in the mouse immune system, they were able to boost immune "memory" in those mice-work that may one day help doctors increase the effectiveness of human vaccines designed to prevent viral infections.

Research suggests pomegranate seed extract could stimulate uterine contractions

The team identified beta-sitosterol - a steroid that can inhibit the absorption of cholesterol in the intestine - as the main constituent of pomegranate seed extract. The research suggests that pomegranate extract could be used as a natural stimulant to encourage the uterus to contract during labour.

New insight into reprogramming of cells

A discovery by Babraham scientists brings new insight into how cells are reprogrammed and a greater understanding of how the environment, or factors like nutritional signals, can interact with our genes to affect health. As an embryo develops, cells acquire a particular fate, for example becoming a nerve or skin cell. The findings, reported online in the journal Nature, pinpoint a protein called AID as being important for complete cellular reprogramming in mammals.

Blocking CRF may prevent excessive alcohol consumption

A team of scientists from The Scripps Research Institute has found that a specific stress hormone, the corticotropin-releasing factor (CRF), is key to the development and maintenance of alcohol dependence in animal models.
