Five genes identified that play major role in Takayasu arteritis
Researchers have uncovered the genetics behind what makes some people susceptible to Takayasu arteritis, a debilitating disease that can lead to poor circulation, easy tiredness in the legs and arms, organ damage and stroke. A study led by the University of Michigan has identified five genes tied to Takayasu arteritis, an inflammation that damages the aorta and can lead to narrowed arteries, aneurysms, high blood pressure, and heart failure. The findings appear in the August issue of The American Journal of Human Genetics...

Emergency physicians distinguish between Bell's palsy and stroke
Emergency physicians correctly identified nearly 100 percent of patients with Bell's palsy, the symptoms of which are nearly identical to potentially life-threatening diseases such as stroke and brain tumors. The results of a study of 6 years of California patient records were published online yesterday in Annals of Emergency Medicine ("Potential Misdiagnoses of Bell's Palsy in the Emergency Department")...

Study suggests role for adenosine in molecular processes involved in epilepsy
Silk has walked straight off the runway and into the lab. According to a new study published in the Journal of Clinical Investigation, silk implants placed in the brain of laboratory animals and designed to release a specific chemical, adenosine, may help stop the progression of epilepsy. The research was supported by the National Institute of Neurological Disorders and Stroke (NINDS) and the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which are part of the National Institutes of Health...

Gender gap in stroke treatment likely due to delay by women seeking care
Women with clot-caused strokes are less likely than men to arrive at the hospital in time to receive the best treatment, according to a European study reported in the American Heart Association journal Stroke. In the study, 11 percent of women with acute ischemic strokes were treated with the clot-dissolving medication alteplase, compared with 14 percent of men. Study participants included 5,515 patients at 12 hospitals in the Netherlands...

Stem cell discovery: Astrocytes could repair stroke brain damage
Stem cell researchers have discovered that astrocytes may prove useful against stroke and other brain disorders. Astrocytes - neural cells that form the blood-brain barrier and so control what can and cannot enter the brain from the blood supply - have previously been overlooked in this area of stroke research. A collaborative study published in Nature Communications suggests that astrocytes can do far more than simply support nerve cells (neurons)...

Motor relearning program improves neurological function of brain ischemia
The motor relearning program can significantly improve various functional disturbance induced by ischemic cerebrovascular diseases. However, its mechanism of action remains poorly understood. According to a study published in Neural Regeneration Research (Vol. 8, No. 16, 2013), models of ischemic brain injury in the rhesus macaque were induced by electrocoagulation of the M1 segment of the right middle cerebral artery, then the motor relearning program was after model establishment...

Could your 3D printer make you ill?
Commercially available desktop 3D printers emit potentially harmful nano-sized particles into indoor air, according to researchers at the Illinois Institute of Technology. The researchers, who have published their work in the journal Atmospheric Environment, say inhaling a high amount of these particles has been associated with adverse health conditions, such as asthma and cardiorespiratory illnesses, and studies have linked elevated ultrafine particle (UFP) concentrations with increased hospital admissions for stroke...

Stem cell study uncovers brain-protective powers of astrocytes
One of regenerative medicine's greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons - the primary movers of electrical impulses in the brain - to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task...

Stem cell survival after transplantation impacted by melatonin pre-treatment
When melatonin, a hormone secreted by the pineal gland, was used as a pre-treatment for mesenchymal stem cells (MSCs) prior to their transplantation into the brains of laboratory animals to repair damage from stroke, researchers in China found that the stem cells survived longer after transplantation. Previous studies had shown that 80 percent of transplanted MSCs died within 72 hours of transplantation. By contrast, the melatonin pre-treatment "greatly increased" cell survival, said the researchers...

Quickly clearing away damaged proteins may help prevent neurodegenerative disorders
Recycling is not only good for the environment, it's good for the brain. A study using rat cells indicates that quickly clearing out defective proteins in the brain may prevent loss of brain cells. Results of a study in Nature Chemical Biology suggest that the speed at which damaged proteins are cleared from neurons may affect cell survival and may explain why some cells are targeted for death in neurodegenerative disorders. The research was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health...

Detrusor overactivity post-stroke responds to electroacupuncture
Detrusor overactivity is common after stroke, and is characterized by frequent micturition and urinary incontinence. However, the optimal treatment for post-stroke detrusor overactivity remains unclear. According to a study reported in Neural Regeneration Research (Vol. 8, No...

The stroke-lowering benefits of regular physical activity
Breaking a sweat while working out regularly may reduce your risk of stroke, according to new research in the American Heart Association journal Stroke. str In a study of more than 27,000 Americans, 45 years and older who were followed for an average of 5.7 years, researchers found: One-third of participants reported being inactive, exercising less than once a week. Inactive people were 20 percent more likely to experience a stroke or mini-stroke than those who exercised at moderate to vigorous intensity (enough to break a sweat) at least four times a week...

Susceptibility genes for cerebral infarction or hemorrhage in the Han in Hunan, China
Atherosclerosis is widely recognized as an independent risk factor for stroke, and its occurrence is closely related to lipid metabolism. Numerous studies using transgenic and knockout animals have shown that scavenger receptor class B type I has a protective effect against atherosclerosis. Previous studies of scavenger receptor class B type I gene polymorphisms have focused on the exon 1 G4A polymorphism and the exon 8 C1050T polymorphism, and these polymorphic loci impact blood lipid levels and are involved in the dyslipidemia in diabetes patients...

Ischemic Stroke Induced By An Embolic Agent In The Rete Mirabile In Miniature Pigs
Rodents are frequently used as animal models for ischemic stroke studies induced by middle cerebral artery occlusion. However, their anatomic structure is significantly different from humans. Thus, recent studies have focused on developing stroke models in large animals with similar anatomic structure as the human brain. The swine have several properties resembling the human brain, including brain volume and weight, quantity of cortical gyri and the percentage of white matter to gray matter...

'Risky' Stroke Prevention Procedure May Be Safe In Some Patients
A major study published in the Lancet Neurology, funded by the Medical Research Council (MRC) and the Stroke Association, has found that stenting in the carotid artery (in the neck) is as safe as carotid artery surgery at reducing stroke risk in some patients. The research, which was part of the International Carotid Stenting Study (ICSS), reveals that stenting is equally as safe as surgery in patients who show few signs of changes to brain tissue (known as white matter lesions) in a brain scan...
