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.
According to a new study led by Anya Topiwala of Oxford Population Health, a division of the University of Oxford in the United Kingdom, and published on March 22nd, 2023 in the open-access journal PLOS ONE, changes in the brain caused by Alzheimer’s disease are connected to telomeres shortening, the protective caps on the ends of chromosomes that shorten as cells age.
More than 37 million Americans have diabetes, and approximately 90-95% have Type 2 diabetes.
Scientists at the Francis Crick Institute have found that high consumption of a common artificial sweetener, sucralose, lowers activation of T-cells, an important component of the immune system, in mice.
A high blood caffeine level might curb the amount of body fat a person carries and their risk of type 2 diabetes, suggests research published in the open access journal BMJ Medicine.
Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.
Physician-scientists at The Texas Heart Institute announced today the results of the largest cell therapy trial to date in patients with chronic heart failure due to low ejection fraction.
Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.
Until now, the use of models to study the barrier that differentiates the circulatory and nervous systems has been either limited or extremely complex. ETH Zurich researchers have created a more accurate model that can also be used to effectively investigate new treatments for brain tumors.
Obesity causes many health problems and worsens several chronic illnesses, including type 2 diabetes and cardiovascular disease, however, some obese people are more susceptible to complications than others.
The human brain prepares skilled movements such as playing the piano, competing in athletics, or dancing by 'zipping and unzipping' information about the timing and order of movements ahead of the action being performed, a new study reveals.
A tool was developed by researchers to forecast the impact of various dietary plans on both cancerous and healthy cells.
Researchers investigating the fundamental brain mechanics of autism spectrum disorder have discovered that a gene mutation known to be connected with the illness causes considerably more overstimulation of brain cells than in neuronal cells without the mutation.
Damaged protein clusters in the brain are a hallmark of many neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and others. Although they have made significant efforts, scientists have only partially succeeded in finding treatments for these conditions by removing these toxic clusters.
The treatment of various tumors has been transformed by cell-based immunotherapy, often known as CAR-T cell therapy. To target and combat specific forms of leukemia and lymphoma, the treatment employs genetically engineered T cells.
Scientists at the Francis Crick Institute have identified a group of latent stem cells that respond to injury in the central nervous system of mice. If a similar type of cell exists in humans, they could offer a new therapeutic approach to treat brain and spinal cord injuries.
According to research published today in the Journal of Clinical Investigation by neurologists and immunologists at the University of Pittsburgh, a special subgroup of white blood cells provides mice with quick-acting and long-lasting protection against ischemic stroke.
The virus that causes COVID-19, SARS-CoV-2, can directly infect a specialized type of kidney cell.
For World Creativity and Innovation Day, we asked leading experts within the life sciences industry 'What does creativity and innovation look like to you within science?'.
The in-built mechanism of recycling dead or poisonous material to preserve the health of human cells is critical to general health.
Sodium is an essential micronutrient, but the amount we need is small. Three slices of bread or one teaspoon of table salt will do it, and chances are your daily sodium intake is far greater.
