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.

Natural molecule can effectively block the binding of human antibodies to SARS-CoV-2

Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Inhibiting a specific protein could increase tumor sensitivity to PARP inhibitors

Researchers at the Francis Crick Institute have found that blocking a specific protein could increase tumor sensitivity to treatment with PARP inhibitors. Their work published in Science , suggests combining treatments could lead to improved therapy for patients with inheritable breast cancers.

Unique mini-microscope enables imaging of brain activity in freely moving mice

Researchers from the University of Minnesota Twin Cities College of Science and Engineering and Medical School have developed a unique head-mounted mini-microscope device that allows them to image complex brain functions of freely moving mice in real time over a period of more than 300 days.

New genetic evidence points to novel therapies for “silent” stroke

According to a study, researchers have discovered new genetic clues in individuals who had experienced small but often apparently “silent” strokes.

Stem cell therapy could help restore debilitating muscle loss that happens with age

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.

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.

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.

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.

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.
