Study: Glucose levels, vascular damage contribute to dementia

High blood-sugar levels, such as those linked with Type 2 diabetes, make beta amyloid protein associated with Alzheimer's disease dramatically more toxic to cells lining blood vessels in the brain, according to a new Tulane University study published in latest issue of the Journal of Alzheimer's Disease.

New understanding of sperm capacitation may improve IVF success rates

Two new papers from reproductive biologists at the University of Massachusetts Amherst, with international partners, report advances in understanding the basic processes of sperm capacitation that may one day improve success rates of in vitro fertilization (IVF) by providing a shortcut to bypass problems, and may eventually lead to a male contraceptive.

Serotonin 2C receptors induce fast-acting antidepressant effects in mice

More than 1 in 10 Americans take antidepressants, but these medications can take weeks-and for some patients, months-before they begin to alleviate symptoms. Now, scientists from the University of Chicago have discovered that selectively blocking a serotonin receptor subtype induces fast-acting antidepressant effects in mice, indicating a potential new class of therapeutics for depression. The work was published Oct. 29 in Molecular Psychiatry.

Physicians believe electronic cigarettes should be treated no differently than tobacco products

The potential dangers of electronic cigarettes have members of the Pennsylvania Medical Society concerned, and until more is known about the products, the state's physicians believe they should be treated no differently than tobacco products.

New research reveals iron deposits in brain play a role in pathology of MS

While it's been known for over a century that iron deposits in the brain play a role in the pathology of Multiple Sclerosis (MS), new imaging research from Western University (London, Canada) helps to answer the question of whether these accumulations are a cause or consequence of the disease.

Lipid secreted by tumors inhibits immune response against cancer

Researchers at National Jewish Health have discovered how a lipid secreted by cancer tumors prevents the immune system from mounting an immune response against it. When lysophosphatidic acid binds to killer T cells, it acts almost like an "invisibility cloak," preventing T cells from recognizing and attacking nascent tumors.

Study shows how wrong levels of protein linked with AD can lead to dangerous blockages in brain cells

Scientists have known for some time that a protein called presenilin plays a role in Alzheimer's disease, and a new study reveals one intriguing way this happens.

Regular cannabis users have increased levels of impulsive behaviour, reveals research

New cocaine and cannabis research reveals that regular cannabis users have increased levels of impulsive behaviour. It had previously been argued that this increased impulsivity after cannabis administration was only experienced by occasional users, but that regular users were no longer affected in this way.

Research findings open up possibility for developing potent anti-clotting drugs

Researchers at the University of Illinois at Chicago have discovered a molecular switch that causes small, beneficial clots that stop bleeding to enlarge further during wound healing. By blocking this switch in lab mice, the researchers prevented small clots from growing -- a process that can pose a danger in humans -- while preserving their ability to staunch bleeding

Children with poor motor performance have poor academic skills during first 3 years of school

Children with poor motor performance at the school entry were found to have poorer reading and arithmetic skills than their better performing peers during the first three years of school.

Study: Light enhances brain activity during cognitive task even in blind people

Light enhances brain activity during a cognitive task even in some people who are totally blind, according to a study conducted by researchers at the University of Montreal and Boston's Brigham and Women's Hospital.

Nurturing home life may offset negative changes in brain anatomy among poor children

Growing up in poverty can have long-lasting, negative consequences for a child. But for poor children raised by parents who lack nurturing skills, the effects may be particularly worrisome, according to a new study at Washington University School of Medicine in St. Louis.

Cognitive reappraisal may have negative effects on psychological health

Being able to regulate your emotions is important for well-being, but new research suggests that a common emotion regulation strategy called "cognitive reappraisal" may actually be harmful when it comes to stressors that are under our control. The study is published in Psychological Science, a journal of the Association for Psychological Science.

Study reveals that specific protein may assist breast cancer cells in metastasizing

A new study by University of Kentucky Markey Cancer Center researchers Min Chen and Kathleen O'Connor shows that a specific protein may assist breast cancer cells in metastasizing.

Research findings could help define new vaccination applications

New research from the Masonic Cancer Center, University of Minnesota, and the University of Minnesota Center for Immunology has identified key proteins that influence immune response strategies, a finding that could influence new vaccination approaches.

Researchers identify risk factors, protective medication for people living with lupus

According to research presented this week at the American College of Rheumatology Annual Meeting in San Diego, researchers have identified three potentially modifiable risk factors and one protective medication that may improve the health of people living with lupus.

Brief exposure to anabolic steroids may have long lasting performance-enhancing effects

Brief exposure to anabolic steroids may have long lasting, possibly permanent, performance-enhancing effects, shows a study published today [28 October] in The Journal of Physiology.

Biomarker may predict poor pregnancy outcomes in lupus patients

Researchers at Hospital for Special Surgery in New York City have identified a biomarker that may predict poor pregnancy outcomes in lupus patients.

Study confirms the "seed and soil" theory of metastasis

Oncologists have long puzzled over the fact that after cancer treatment, single cancer cells that are dispersed throughout the body - so-called disseminated tumor cells - are quick to grow and form secondary tumors called metastases in certain organs, while in other organs they metastasize more slowly, sometimes decades later. Such is the case with head and neck squamous cell carcinoma cells, which remain dormant when lodged in bone marrow but rapidly form tumors when they make their way into the lungs.

International researchers identify 11 new genes linked to Alzheimer's disease

An international group of researchers has identified 11 new genes that offer important new insights into the disease pathways involved in Alzheimer's disease. The highly collaborative effort involved scanning the DNA of over 74,000 volunteers-the largest genetic analysis yet conducted in Alzheimer's research-to discover new genetic risk factors linked to late-onset Alzheimer's disease, the most common form of the disorder.
