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.
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.
A recently discovered chemical compound helped elderly mice with obesity lose fat and weight, add muscle and strength, reduce age-related inflammation and increase physical activity, a new study shows.
In a breakthrough discovery, scientists from The University of Texas Health Science Center at San Antonio today reported that inhibiting a liver enzyme in obese mice decreased the rodents' appetite, increased energy expenditure in adipose (fat) tissues and resulted in weight loss.
A risk score based on a gene map predicted the likelihood of high blood pressure leading to heart problems or stroke in people with Type 2 diabetes, according to a study published today in the American Heart Association's peer-reviewed journal Hypertension.
Findings from a new Cleveland Clinic-led phase 1 trial show that an experimental "gene silencing" therapy reduced blood levels of lipoprotein(a), a key driver of heart disease risk, by up to 98%.
A rare type of brain blood vessel malformation known as a cavernous angioma affects more than one million Americans and carries a lifetime risk of stroke and seizures.
Macrophages travel through our arteries, gobbling fat the way Pac-man gobbled ghosts. But fat-filled macrophages can narrow blood vessels and cause heart disease.
Understanding how the brain functions, particularly how information is processed during different activities, is difficult without knowing how many axons are in the brain and how many connect different functional regions.
Research from the Francis Crick Institute has revealed a key mechanism which increases tolerance to drugs amongst microbial communities.
New research may help scientists locate immature cells in the central nervous system that could shed light on the causes of neurodegenerative diseases like multiple sclerosis-;and autoimmune disease that affects the brain and nervous system-;and allow for the development of better therapeutic treatments.
As a molecular machine found in the cells of all organisms, the ribosome is responsible for making new proteins.
Take a cell-deep tour of a brain afflicted with Alzheimer's disease, and you will find minuscule clumps of protein that seem suspicious. Ever since the 1980s, when neuroscientists began identifying these protein tangles, researchers have discovered that other brain diseases have their own tangled-protein signatures.
A new imaging method has been designed and tested by scientists from Johns Hopkins Medicine.
Scientists from two independent research teams have discovered how the mislocalization of a protein, known as TDP-43, alters the genetic instructions for UNC13A, providing a possible therapeutic target that could also have implications in treating amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and other forms of dementia.
Scientists at UCL have developed a new technique that uses microscopic magnetic particles to remotely activate brain cells; researchers say the discovery in rats could potentially lead to the development of a new class of non-invasive therapies for neurological disorders.
Researchers at the University of Illinois Chicago found promising results in their search for a treatment to stop nerve cell degeneration that happens in some types of disorders, such as hereditary spastic paraplegia and Parkinson's disease, which can cause significant disability.
In this interview, we speak to Dr. Santiago Miriuka, CEO of MultiplAI Health, about the importance of having diverse genomics data in research.
