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.

Study Reveals Titin Mutation Effects on Cardiac Development and Atrial Fibrillation

Millions of adults have atrial fibrillation -; an irregular beating of the upper chambers of the heart that yields increased risk of heart failure, stroke and death.

Study Reveals How Sweet Taste Receptor Regulates Blood Sugar and Insulin

The rich research portfolio of the Monell Chemical Senses Center on sweet taste goes way back: Monell scientists were one of four teams in 2001 that found and described the mammalian sweet taste receptor – TAS1R2-TAS1R3.

Unlocking Glucose-Driven Mechanisms of Immunosuppression in Glioblastoma

The Wistar Institute assistant professor Filippo Veglia, Ph.D., and team, have discovered a key mechanism of how glioblastoma -; a serious and often fatal brain cancer -; suppresses the immune system so that the tumor can grow unimpeded by the body's defenses.

Rare YKT6 Gene Variants Linked to New Neurological Disorder

A recent collaborative study has discovered rare variants in the YKT6 gene as the cause of a new neurological disorder characterized by developmental delays along with severe progressive liver disease and a potential risk for liver cancer.

New Study Sheds Light on Blood-Brain Barrier Dysfunction in Aging

The central nervous system requires a tightly controlled environment for the neurons in the brain to function properly and be able to process information. The blood-brain barrier, which is maintained by specific brain endothelial cells lining blood vessel inner walls, controls the exchange of chemicals between the neurological and circulatory systems.

Cells Harvested From Urine May Have Diagnostic Potential for Kidney Disease

Genes expressed in human cells harvested from urine are remarkably similar to those of the kidney itself, suggesting they could be an important non-invasive source of information on the kidney.

New Biomarker Offers Early Detection of ALS and FTD

Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig's disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning -; the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.

AI Research Gives Unprecedented Insight Into Heart Genetics and Structure

A ground-breaking research study has used AI to understand the genetic underpinning of the heart’s left ventricle, using three-dimensional images of the organ.

Tandem Repeat Expansions Linked to Cardiomyopathy Risk, Reveals Study

In the first study to use whole genome sequencing to examine tandem repeat expansions in heart conditions, scientists at The Hospital for Sick Children (SickKids) have laid the groundwork for early detection of and future precision therapies for cardiomyopathy.

Gut Microbial Metabolite Linked to Increased Thrombosis Risk in COVID-19 Patients

A gut microbial metabolite called 2-methylbutyrylcarnitine (2MBC) plays a role in exacerbating thrombosis -- the formation of blood clots – researchers report February 23rd in the journal Cell Metabolism.

Researchers Unveil New Mechanism of Immune Cell Training in Thymus Gland

Immune cells must learn not to attack the body itself. A team of researchers from the Technical University of Munich (TUM) and the Ludwig Maximilian University of Munich (LMU) has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the "training" of the T cells in the thymus gland.
