Hair provides proof of the link between chronic stress and heart attack
Researchers have provided the first direct evidence using a biological marker, to show chronic stress plays an important role in heart attacks. The scientists developed a method to measure cortisol levels in hair providing an accurate assessment of stress levels in the months prior to an acute event such as a heart attack....

New animal model for hemophilia A developed
Researchers have developed a new animal model for studying hemophilia A, with the goal of eventually treating people with the disorder. Hemophilia A, a hereditary defect that prevents blood from clotting normally, is caused by a variety of mutations in the factor VIII gene....

Capsaicin can act as co-carcinogen, study finds; Chili pepper component linked to skin cancer
New research links capsaicin, a component of chili peppers, to skin cancer. While the molecular mechanisms of the cancer-promoting effects of capsaicin are not clear and remain controversial, the new research has shown a definite connection to formation of skin cancer through various laboratory studies....

Cigarette smoke may contribute to lung inflammation through a new chemical pathway
Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to new findings. Researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation....

Problem of fake medicines in developing countries could be solved, experts say
Counterfeiting of drugs is a huge industry. In Africa the situation is extremely serious. Half of the malaria medication sold there could be ineffective or even harmful. There is currently no good way to identify counterfeit drugs. However, researchers in Sweden and the UK have now developed a technique that could resolve the situation....

Value of oxygen therapy in end-of-life care challenged in new study
Millions of patients with advanced disease in palliative care settings receive oxygen therapy to help them breathe more easily. But a new study says roughly half of them don't benefit from the intervention, and among those who do benefit, it doesn't make a bit of difference whether they get pure oxygen or just plain old room air -- both offer equal benefit....
