Protein unfolding key to understanding blood clot mechanics

Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remaining pliable and flexible. On the other hand, fibrin provides a scaffold for thrombi, clots that block blood vessels and cause tissue damage, leading to myocardial infarction, ischemic stroke, and other cardiovascular diseases. How does fibrin manage to be so strong and yet so extensible under the stresses of healing and blood flow?

Distinctive gene expression in brains of relapsing heroin-addicted rats

A group of genes whose expression is significantly altered following exposure to drug paraphernalia after an enforced 'cold-turkey' period have been identified. Researchers writing in the open access journal BMC Neuroscience studied gene expression in the brains of heroin-addicted rats, identifying those genes that may be involved in precipitating a relapse.

Scientists create stem cells from developing sperm

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells.

Experts on vertebroplasty contend recent vertebroplasty studies are misleading

Two studies released today in the New England Journal of Medicine claim to demonstrate that vertebroplasty, a procedure to treat some painful spine fractures, is not effective. This is incorrect, as both studies actually demonstrate a significant improvement in patients' pain and ability to function normally.

Beetroot juice boosts stamina, may help endurance athletes

Drinking beetroot juice boosts your stamina and could help you exercise for up to 16% longer. A University of Exeter led-study, published today (Thursday 6 August 2009), shows for the first time how the nitrate contained in beetroot juice leads to a reduction in oxygen uptake, making exercise less tiring.
