The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Combination of tPA and 3K3A-APC may effectively treat stroke

A team led by a physician-scientist at the University of Southern California (USC) has created an experimental drug that reduces brain damage and improves motor skills among stroke-afflicted rodents when given with federally approved clot-busting therapy.

Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

Mu-opioid receptors put brakes on appetite

Activation of mu-opioid receptors in the nerves of the portal vein walls triggers a gut–brain neural circuit that leads to feelings of satiety, researchers report in Cell.

Light reflexes during CPR may indicate survival chances

The presence of the papillary light reflex during cardiopulmonary resuscitation is associated with early survival and favorable neurologic status during recovery, suggest findings from a case series.

Sensory device may help blind ‘see’

Study results indicate that the use of a sensory substitution device may allow individuals with visual impairments to experience a form of spatial awareness conventionally thought to be vision-specific.

Promising path to Parkinson’s disease treatment

Using adult stem cells, Johns Hopkins researchers and a consortium of colleagues nationwide say they have generated the type of human neuron specifically damaged by Parkinson’s disease (PD) and used various drugs to stop the damage.

WCMC receives NHLBI grant to study smoking-induced COPD

Researchers at Weill Cornell Medical College were awarded a $6.5 million grant from the National Heart, Lung, and Blood Institute for a five-year investigation into metabolic changes occurring within airway epithelial cells in the lungs of chronic obstructive pulmonary disease (COPD) patients caused by cigarette smoking. In addition, researchers aim to identify which cigarette smokers are at highest risk of developing COPD as well as novel biomarkers to assist in the development of new therapeutic treatments for the disease.

Study shows why eating less may be therapeutic for people with neuromuscular disorders

A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less - information that ultimately could help people suffering from neuromuscular disorders.

New Alzheimer's model derived from skin cells of patients may prove to be more accurate

Researchers at the Alzheimer's Association International Conference 2012 (AAIC 2012) today reported the creation of a new model of Alzheimer's derived from the skin cells of people with the disease that were reprogramed into Alzheimer's brain cells.

Scientists develop first cell-based model of Alzheimer's disease

A team of scientists at The New York Stem Cell Foundation (NYSCF) Laboratory led by Scott Noggle, PhD, NYSCF-Charles Evans Senior Research Fellow for Alzheimer's Disease, has developed the first cell-based model of Alzheimer's disease (AD) by reprogramming skin cells of Alzheimer's patients to become brain cells that are affected in Alzheimer's.

People with amnestic MCI more likely to die

Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that people with a form of mild cognitive impairment (MCI), a risk factor for developing Alzheimer's disease, have twice the risk of dying compared with cognitively normal people. Those with dementia have three times the risk.
