Adjusting the clocks to summer time affects risk of heart attack

Adjusting the clocks to summer time on the last Sunday in March increases the risk of myocardial infarction in the following week. In return, putting the clocks back in the autumn reduces the risk, albeit to a lesser extent. This according to a new Swedish study published in the prestigious New England Journal of Medicine.

Discovery of mechanism and possible drug treatment for growth of nerve tumors in neurofibromatosis

Researchers studying neurofibromatosis type 1 - a rare disease in which tumors grow within nerves - have found that the tumors are triggered by crosstalk between cells in the nerves and cells in the blood.

Stem cell therapies for heart disease - one step closer

New research from the University of Bristol brings stem cell therapies for heart disease one step closer. The findings reveal that our bodies' ability to respond to an internal 'mayday' signal may hold the key to success for long-awaited regenerative medicine.

Grapes may aid a bunch of heart risk factors

Could eating grapes help fight high blood pressure related to a salty diet? And could grapes calm other factors that are also related to heart diseases such as heart failure? A new University of Michigan Cardiovascular Center study suggests so.

Researchers discover new way to attack some forms of leukemia

Each year, some 29,000 adults and 2,000 children are diagnosed with leukemia, a form of cancer that is caused by the abnormal production of white blood cells in the bone marrow. Current treatments rely primarily on killing the cancer cells, which also destroys normal cells. But what if a way could be found to reprogram cancerous cells back into normal cells? A team of Syracuse University researchers believes it may have found a way to do just that.

Researchers discover how Sonic hedgehog gene controls brain development

University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics.

High-fat diet could promote the development of Alzheimer's

A team of Université Laval researchers has shown that the main neurological markers for Alzheimer's disease are exacerbated in the brains of mice fed a diet rich in animal fat and poor in omega-3s. Details of the study-which suggests that diets typical of most industrialized countries promote the development of Alzheimer's-are outlined in the latest online edition of Neurobiology of Aging.
