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 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.

Researchers identify a valuable source for treating pediatric cancer

For many cancers, doctors are increasingly looking to the DNA that solid tumors shed into the blood stream to help with diagnosis and monitoring.

Researchers discover a gene responsible for urination

In a National Institutes of Health (NIH)-funded study involving both mice and patients who are part of an NIH Clinical Center trial, researchers discovered that a gene, called PIEZO2, may be responsible for the powerful urge to urinate that we normally feel several times a day.

Dopamine and serotonin found to be involved in perception, cognitive capacities

In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.

Enzyme SSH1 impairs disposal of damaged tau and mitochondria leaking toxins

In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.

Researchers discover how synapses find energy to support intense neural conversations

Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses.

Researchers analyze individual cells to build an atlas of the human heart

Scientists have created a cellular and molecular map of the healthy human heart, to understand how this vital organ functions, and to shed light on what goes wrong in cardiovascular disease.

Star-shaped brain cells are essential for blood-brain barrier health, shows study

Hard skulls help protect our brains from physical injuries.In addition to a tough outer shell, brains have internal defenses, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is breached, then health problems arise.
