Link found between Alzheimer's disease and protein regulation in the brain - hope for new treatments

New study from the University of Haifa discovers: Link found between Alzheimer's disease and protein regulation in the brain brings hope for new treatments

* Alzheimer's research has focused primarily on efforts to identify and treat the factors that contribute to familial (genetic) dementia, which is caused by known mutations. This new research sought to understand the mechanisms in the development of Alzheimer's that are linked to molecular response to the metabolic distress that increases with age. *

Many high school football players not concerned about concussions

NEW ORLEANS – Despite an increase in media attention, as well as national and local efforts to educate athletes on the potential dangers of traumatic brain injuries, a new study found that many high school football players are not concerned about the long-term effects of concussions and don't report their own concussion symptoms because they fear exclusion from play. The abstract, "Awareness and Attitudes of High School Athletes Towards Concussions," was presented on Oct. 22, at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans.

Fainting after air travel may indicate pulmonary embolism

Fainting after recent air travel could be a sign of pulmonary embolism (PE), a potentially fatal blockage in the lungs. Syncope or fainting is an uncommon symptom of pulmonary embolism; however, new research presented at CHEST 2012, the annual meeting of the American College of Chest Physicians (ACCP), found that fainting associated with recent air travel may be a key indicator for PE diagnosis. Fainting as a precursor to PE diagnosis was also associated with a saddle embolism, a larger and more life-threatening form of PE, as well as more abnormal ECG readings.

Intermediate glucose control may be better than tight in neurocritical care patients

A new study in BioMed Central's open access journal Critical Care suggests that intensive glycemic control does not reduce mortality in neurocritical care patients and could, in fact, lead to more neurological damage. Complicating the picture, poor glucose control also leads to worse recovery and should be avoided. This study suggests that a strategy to maintain intermediate glucose levels would contribute to better outcomes in these patients.

Natural process activating brain's immune cells could point way to repairing damaged brain tissue

STANFORD, Calif. — The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

Dartmouth researchers explore how the brain perceives direction and location

The Who asked "who are you?" but Dartmouth neurobiologist Jeffrey Taube asks "where are you?" and "where are you going?" Taube is not asking philosophical or theological questions. Rather, he is investigating nerve cells in the brain that function in establishing one's location and direction.

Take control! Exploring how self-discipline works and how we might boost it

Converging scientific evidence – not to mention a great deal of life experience – tells us that self-control is an important ability. It helps us keep our cool, get things done, and resist the things that tempt us. Scientists believe that gaining a clearer understanding of how self-control works could provide critical insights into addressing some of the large-scale problems facing society today, including obesity and addiction.

Salk scientists pinpoint key player in Parkinson's disease neuron loss

LA JOLLA, CA---- By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation, researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease. The findings, reported online October 17th in Nature, may lead to new ways to diagnose and treat the disease.

Science reveals the power of a handshake

New neuroscience research is confirming an old adage about the power of a handshake: strangers do form a better impression of those who proffer their hand in greeting.

Weight loss does not lower heart disease risk from type 2 diabetes

Intervention stopped early in NIH-funded study of weight loss in overweight and obese adults with type 2 diabetes after finding no harm, but no cardiovascular benefits

An intensive diet and exercise program resulting in weight loss does not reduce cardiovascular events such as heart attack and stroke in people with longstanding type 2 diabetes, according to a study supported by the National Institutes of Health.

First micro-structure atlas of the human brain completed

A European team of scientists have built the first atlas of white-matter microstructure in the human brain. The project's final results have the potential to change the face of neuroscience and medicine over the coming decade.

The work relied on groundbreaking MRI technology and was funded by the EU's future and emerging technologies program with a grant of 2.4 million Euros. The participants of the project, called CONNECT, were drawn from leading research centers in countries across Europe including Israel, United Kingdom, Germany, France, Denmark, Switzerland and Italy.

How to prove a sexual addiction

The idea that an individual might suffer from a sexual addiction is great fodder for radio talk shows, comedians and late night TV. But a sex addiction is no laughing matter. Relationships are destroyed, jobs are lost, lives ruined.

Yet psychiatrists have been reluctant to accept the idea of out-of-control sexual behavior as a mental health disorder because of the lack of scientific evidence.

Now a UCLA-led team of experts has tested a proposed set of criteria to define "hypersexual disorder," also known as sexual addiction, as a new mental health condition.

Foster kids do equally well when adopted by gay, lesbian or heterosexual parents

High-risk children adopted from foster care do equally well when placed with gay, lesbian or heterosexual parents, UCLA psychologists report in the first multi-year study of children adopted by these three groups of parents.

The psychologists looked at 82 high-risk children adopted from foster care in Los Angeles County. Of those children, 60 were placed with heterosexual parents and 22 were placed with gay or lesbian parents (15 with gay male parents and seven with lesbian parents).

Stroke patients benefit from carmaker's efficiency

A process developed to increase efficiency and productivity in Japanese car factories has helped improve stroke treatment at Barnes-Jewish Hospital, report researchers at Washington University School of Medicine in St. Louis.

By applying the principles of Toyota's lean manufacturing process, doctors sharply reduced the average time between patient arrival and treatment, known as door-to-needle time, from 58 to 37 minutes.
