Stroke News and Research

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.

Nutritional supplement may reduce the risk of strokes caused by a rare genetic disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered that a widely used nutritional supplement may significantly reduce the risk of fatal strokes caused by a rare genetic disorder.

Processed meat consumption associated with increased risk of dementia

Scientists from the University of Leeds's Nutritional Epidemiology Group used data from 500,000 people, discovering that consuming a 25g serving of processed meat a day, the equivalent to one rasher of bacon, is associated with a 44% increased risk of developing the disease.

Scientists provide a complete phenotypic landscape of SCN2A-related disorders

Researchers from Children's Hospital of Philadelphia (CHOP) affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) have compiled a complete genetic and clinical analysis of more than 400 individuals with SCN2A-related disorder, which has been linked to a variety of neurodevelopmental disorders, including epilepsy and autism.

Catechin-type flavonoid compounds in tea relax blood vessels by activating ion channel proteins

A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall.

New breakthrough in understanding how single-cell algae keep track of light as they swim

Scientists have made a pivotal breakthrough in the quest to understand how single-cell green algae are able to keep track of the light as they swim.

Patients' own stem cells can be used to heal injured spinal cord

Intravenous injection of bone marrow derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report Feb. 18 in the Journal of Clinical Neurology and Neurosurgery.

Cryogenic electron microscopy reveals shape of glutamate transporters involved in neurological diseases

An international research team has uncovered the shape of the glutamate transporter and helps explain how the human brain cells interact with each other.

Research links blood-clotting protein with CNS B-cell lymphoma growth

In people with central nervous system (CNS) lymphoma, cancerous B cells--a type of white blood cell--accumulate to form tumors in the brain or spinal cord, often in close proximity to blood vessels.

Combining cholesterol-lowering medications and lifestyle interventions may yield better benefits

Combining healthy lifestyle interventions reduces heart disease through beneficial effects on different lipoproteins and associated cholesterols, according to a study published February 9 in eLife.

Genomic test helps identify prostate cancer patients who may benefit from hormone therapy

A commercially available genomic test may help oncologists better determine which patients with recurrent prostate cancer may benefit from hormone therapy, according to new research from the Johns Hopkins Kimmel Cancer Center and 15 other medical centers.

New tool reveals potentially risky DNA alterations at site of CRISPR gene repair

Scientists have developed an affordable, downloadable app that scans for potential unintended mistakes when CRISPR is used to repair mutations that cause disease.

Study uncovers how cells actively seek information to make better collective decisions

Cells, like humans, cast votes to make decisions as a group. But how do they know what to vote for? Researchers at the Francis Crick Institute and King's College London have uncovered how cells actively seek information in order to make faster and better collective decisions to coordinate the growth of new blood vessels. This provides a new basis for understanding intelligence in cells.

Genetic changes in tumors could help predict patient's response to immunotherapy drugs

Researchers at the Francis Crick Institute, the UCL Cancer Institute, and the Cancer Research UK Lung Cancer Centre of Excellence have identified genetic changes in tumours which could be used to predict if immunotherapy drugs would be effective in individual patients.

Venom of Tiger Rattlesnakes may advance genetic science

Among all rattlesnake species, the Tiger Rattlesnake has the simplest yet most lethal venom. Now, a new study performed by a team of researchers can describe the genetics behind the venomous bite of the Tiger Rattlesnake.

Researchers discover genetic risk factor for stroke

A research team from Geisinger Health System has detected a common genetic variant as a risk factor for stroke, particularly in patients aged more than 65.

Innovative gene therapy approach for regeneration of functional new neurons

Spinal cord injury (SCI) often causes disability and seriously compromises quality of life. While decades of research have made significant progress in axonal regeneration after SCI, most of the interventions have not been translated into clinical therapies.

Study may lead to new treatments for certain types of disease

Researchers at the Francis Crick Institute have found a new way to prevent some tumours from repairing their own DNA, a function that is essential for cancer cell survival. This discovery could lead to much needed new treatments for certain types of the disease.

Water intake may effectively mitigate obesity and metabolic syndrome

Researchers at the University of Colorado Anschutz Medical Campus have discovered that fructose stimulates the release of vasopressin, a hormone linked to obesity and diabetes.

Study shows tRNA fragments play a key role in ischemic stroke

An ischemic stroke occurs when the homeostasis of the body and brain is highly disrupted. The immune system, among other things, activates an inflammatory response that can either overshoot or change into an immune deficiency.

New genetic associations predict susceptibility to Takayasu arteritis

A team of international collaborators, headed by scientists from the University of Pittsburgh School of Medicine, have detected novel genetic associations that can estimate the susceptibility of individuals to Takayasu arteritis—a rare inflammatory disease.
