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.
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.
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.
An international research team has uncovered the shape of the glutamate transporter and helps explain how the human brain cells interact with each other.
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 healthy lifestyle interventions reduces heart disease through beneficial effects on different lipoproteins and associated cholesterols, according to a study published February 9 in eLife.
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.
Scientists have developed an affordable, downloadable app that scans for potential unintended mistakes when CRISPR is used to repair mutations that cause disease.
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.
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.
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.
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.
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.
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.
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.
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.
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 think they have found a fountain of youth, and it is unique to a few French Canadian families.
In a current opinion article "Reduction of environmental pollutants for prevention of cardiovascular disease: it's time to act", published in the European Heart Journal this week.
In this interview, AZoLifeSciences speaks to Professor Kuhnle about his latest research which showed that a diet high in flavanols may lower blood pressure.
For many cancers, doctors are increasingly looking to the DNA that solid tumors shed into the blood stream to help with diagnosis and monitoring.
