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.

Clinical grade stem cells to be manufactured by Stemedica as it awaits FDA approval of an IND to commence clinical trials

Stemedica Cell Technologies, Inc. USA, a leader in adult stem cell research and manufacturing, has requested a pre-Investigational New Drug (IND) meeting with the U.S. Food and Drug Administration ("FDA") to discuss a proposed IND to use Stemedica's proprietary line of allogeneic mesenchymal bone marrow cells (adult human) as a treatment for ischemic stroke.

Chinese scientists present study on oxycholesterol's cholesterol-boosting effects at 238th ACS meeting

Health-conscious people know that high levels of total cholesterol and LDL cholesterol (the so-called "bad" cholesterol) can increase the risk of heart attacks. Now scientists are reporting that another form of cholesterol called oxycholesterol - virtually unknown to the public - may be the most serious cardiovascular health threat of all. Scientists from China presented one of the first studies on the cholesterol-boosting effects of oxycholesterol here today at the 238th National Meeting of the American Chemical Society. The researchers hope their findings raise public awareness about oxycholesterol, including foods with the highest levels of the substance and other foods that can combat oxycholesterol's effects.

New website launched to determine sleep disorder

Nearly 20 million Americans suffer from sleep apnea, a serious health condition that has been linked to increased risks for obesity and weight gain, heart attack, stroke, high blood pressure, asthma and depression. Sleep apnea has also been cited by experts as the number one cause of car accidents. Ninety-five percent of sleep apnea cases go undiagnosed, putting the health of millions of Americans at risk.

InterMune receives $20 million event payment from Roche for initiating the Phase 2b trial of RG7227/ ITMN-191

Roche (SIX: ROG.VX; RO.S, OTCQX: RHHBY) and InterMune, Inc. (Nasdaq: ITMN) today announced that the first patient has been dosed in a Phase 2b study evaluating the hepatitis C virus (HCV) protease inhibitor, RG7227/ ITMN-191, in combination with PEGASYS(R) (pegylated interferon alfa-2a) and COPEGUS(R) (ribavirin). The study, to be conducted at 45 sites globally, will further define the safety and efficacy profile of RG7227/ ITMN-191, for a treatment duration of up to 24 weeks. Approximately 300 treatment-naive patients chronically infected with HCV genotype 1 - the most difficult to treat form of the virus - will participate.

Discovery of key factor that stimulates brain cancer cells to spread

Researchers funded by the National Institutes of Health have found that the activity of a protein in brain cells helps stimulate the spread of an aggressive brain cancer called glioblastoma multiforme (GBM). In a move toward therapy, the researchers showed that a small designer protein can block this activity and reduce the spreading of GBM cells grown in the laboratory.

Sleep apnea increases chances of dying

Nightly bouts of interrupted, oxygen-deprived sleep from a collapsed airway in the upper neck raises the chances of dying in middle-aged to elderly people by as much as 46 percent in the most severe cases, according to a landmark study on sleep apnea by lung experts at Johns Hopkins and six other U.S. medical centers.

Human brain distinctly separates living and non-living objects for processing

For unknown reasons, the human brain distinctly separates the handling of images of living things from images of non-living things, processing each image type in a different area of the brain. For years, many scientists have assumed the brain segregated visual information in this manner to optimize processing the images themselves, but new research shows that even in people who have been blind since birth the brain still separates the concepts of living and non-living objects.
