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.
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.
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.
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.
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.
Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses.
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.
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.
A Rutgers-led team has created a smart drug delivery system that reduces inflammation in damaged nervous tissues and may help treat spinal cord injuries and other neurological disorders.
Rice University engineers will gain a better understanding of brain activity over time with the support of the National Institutes of Health.
TK Adenosine triphosphate, or ATP, is the cellular energy currency that is as valuable to the human body as the dollar is to the US economy. Too high or too low levels of ATP in some cell types have been linked to a variety of diseases.
A team of researchers at Children's Hospital of Philadelphia affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) have combined clinical information with large-scale genomic data to successfully link characteristic presentations of childhood epilepsies with specific genetic variants.
A team of researchers from University of Toronto Engineering and the University of Michigan has redesigned and enhanced a natural enzyme that shows promise in promoting the regrowth of nerve tissue following injury.
A new study offers a better understanding of the properties of important proteins found inside the ciliary membrane.
Air pollution is the world's leading environmental risk factor, and causes more than nine million deaths per year.
New research has shown some of our least favourite vegetables could be the most beneficial when it comes to preventing advanced blood vessel disease.
When it comes to brain cells, one size does not fit all. Neurons come in a wide variety of shapes, sizes, and contain different types of brain chemicals.
Healthy people - especially women - with elevated levels of the heart failure marker NT-proBNP have a lower risk of developing type 2 diabetes.
Switching off a molecular "master regulator" may protect the brain from inflammatory damage and neurodegeneration in Parkinson's disease, reports a study published today in Nature Neuroscience.
