RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

Bypass surgery does not carry long term neurological effects

In a wide retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions a team of U.S. researchers has concluded that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

New statin study shows arrested progression of atherosclerosis

The first study to use cutting edge magnetic resonance imaging to examine the effect of a statin - rosuvastatin (Crestor) - on the fatty plaques in arteries, was presented yesterday at the 75th European Atherosclerosis Society Congress. ORION revealed that rosuvastatin has a beneficial effect on the size and composition of fatty plaques in arteries (specifically the carotid artery in the neck). Fatty plaques that are vulnerable to sudden rupture can cause heart attacks and strokes without warning.

New drug combo helps prevent strokes

A British research team at St. George's Hospital Medical School in London, have found that the addition of the anti-clotting drug Plavix to daily doses of aspirin helps prevent the risk of later strokes better than using aspirin alone.

Increased risk associated with combining carotid artery, coronary artery surgeries

Among patients undergoing evaluation for coronary artery bypass surgery, stroke neurologists are frequently consulted when the patient also has severe carotid artery stenosis (blockage of an artery that supplies blood to the brain).

Evidence suggests bypass surgery free of long-term brain effects

A broad retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions concludes that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

Enlarged waist + elevated triglycerides = heart, stroke risks for women

A tape measure and a simple blood test may be the best way to gauge cardiovascular risk for postmenopausal women, according to a report published today in an obesity-themed issue of Circulation: Journal of the American Heart Association.

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

Brain system that controls the sleep/wake cycle might also play a role in regulating appetite and metabolism

A new mouse study suggests that a brain system that controls the sleep/wake cycle might also play a role in regulating appetite and metabolism. Mice with a mutation in a gene called "Clock," which helps drive circadian rhythm, ate significantly more and gained more weight.

Body's 24-hour internal clock linked to obesity and diabetes

Obesity and diabetes in both adults and children are rising at alarming rates and a wide range of culprits -- super-sized food portions, lack of exercise due to television, computers, suburban sprawl and loss of gym classes, high-fat and fast foods, sugar-laden drinks and psychological trauma -- have been blamed.

Antibiotic treatment does not reduce risk of secondary cardiac events

Taking antibiotics weekly for one year does not reduce the risk of a heart attack or other cardiac event for patients with stable coronary artery disease, according to a study funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health. It is published in the April 21, 2005, edition of the New England Journal of Medicine.

Brain-injury rehabilitation depends on acetylcholine circuitry

The ability of the brain to recover from such injury as stroke or trauma depends on a particular circuitry of neurons that "talk" to one another using the brain chemical acetylcholine, researchers led by James Conner and Mark Tuszynski in the Neural repair Group at UCSD have discovered.

Researchers insert engineered human stem cells into the spinal cords of ALS-afflicted rats

Unveiling a delivery method that may one day help surgeons treat the deadly neurodegenerative disease amyotrophic lateral sclerosis (ALS), researchers at the University of Wisconsin-Madison have inserted engineered human stem cells into the spinal cords of ALS-afflicted rats.

Australian researchers develop safer and more effective aspirin

Monash University researchers and staff of the Melbourne-based biotechnology company Cerylid Biosciences Ltd, have discovered and developed a new class of anti-clotting drugs that appears to be more effective than aspirin at preventing disease-causing blood clots and has fewer side effects.

Statins used before or after strokes improve outcomes

New research into the use of statins before or after a stroke has shown that a patients recovery after an ischemic stroke can be improved.

Eat your fruits and veggies - your body will thank you and your mother will be happy!

Eat your fruits and veggies - your body will thank you and your mother will be happy! And if that's not reason enough, a new study suggests antioxidant-rich fruits and vegetables may limit brain damage from stroke and other neurological disorders.

Protein that regulates cholesterol levels may lead to new drug targets in the fight against obesity

A protein that regulates cholesterol levels in the body also is responsible for maintaining a healthy balance between fat storage and fat burning, according to a UT Southwestern Medical Center study that may lead to new drug targets in the fight against obesity.

Breakdown in brain cell communication may contribute to the most common biochemical cause of mental retardation

The process is akin to a baseball game gone bad. Imagine if a pitcher were joined by six players simultaneously winding up on the mound. Crouched behind home plate, the single catcher would soon be overwhelmed. Even if the coach sent in teammates to catch the extra balls, confusion would reign on the field.

Pfizer voluntarily withdraws Bextra from New Zealand market

Pharmaceutical company Pfizer is voluntarily withdrawing the Cox-2 medicine Bextra from the New Zealand market following a request from Medsafe to suspend distribution and marketing, and will recall supplies of Bextra progressively from wholesale and pharmacy shelves over the next few days.

Tamoxifen still not popular with women at risk of breast cancer

Tamoxifen still not popular with women at risk of breast cancer A new study has revealed that less than one in five women eligible to take tamoxifen decided to take the drug after being told of its risks and benefits.

Research suggests a central role for NMDA receptors in learning and memory

Learning and memory are processes that link experience with behavior and therefore play central roles in our daily experience. That there exists a physical basis for these processes seems at first hard to imagine--except for the fact that physical disruptions in the brain, such as stroke or disease, can make them go wrong.
