Vitamin B reduces risk of developing Alzheimer's disease

Adults who eat the daily recommended allowance of folates - B-vitamin nutrients found in oranges, legumes, leafy green vegetables and folic acid supplements - significantly reduce their risk of developing Alzheimer's disease, according to results from a long-term National Institute on Aging study of diet and brain aging.

Oxytocin and ingestive behavior

More than 15 years ago Edward Stricker and Joseph Verbalis reported that oxytocin (OT) is involved in the neural control of food and salt intake in adult rats. Linda Rinaman at the University of Pittsburgh is investigating the anatomical organization of this system, and also is taking a developmental approach to determine how OT modulates eating and digestion.

Plasma exchange treatment shown most helpful for severe attacks in subtype of MS patients

A Mayo Clinic study demonstrates that only those multiple sclerosis (MS) patients with evidence for antibody deposition or complement activation -- immune cells that can cause tissue destruction -- in their lesions are likely to respond to plasma exchange, a treatment for acute MS attacks.

Key step in the production of beta-amyloid

Researchers at UT Southwestern Medical Center have defined a key step in the production of beta-amyloid, a short protein that is thought to be responsible for the development of Alzheimer's disease. Understanding this step may aid in the discovery of drugs that could help block the disease from developing.

Nasal vaccination with a proteosome-based adjuvant and glatiramer acetate clears beta-amyloid in a mouse model of Alzheimer's disease

Alzheimer disease (AD) is the most common form of senile dementia, with no effective treatment available. In a study appearing online on August 11 in advance of print publication of the September 1 issue of the Journal of Clinical Investigation, Howard Weiner and colleagues from Harvard describe a novel immunologic approach for the treatment of AD.

Pig brain cell transplant looks hopeful for treating Huntington's disease

According to researchers at Australian bioscience company Living Cell Technologies (LCT), if approved, pig brain cells wrapped in a seaweed derivative could be implanted into human brains by sometime next year to treat Huntington's disease.

Standardized guidelines for stroke care offer improved outcomes and fewer complications

Patients suffering from a stroke are more likely to have improved outcomes and fewer complications when hospitals use standardized guidelines for stroke care during a patient's admission and discharge from the hospital, according to a study led by researchers at UCSF Medical Center.

Cells direct membrane traffic by channel width

For a glycerol molecule, a measly angstrom's difference in diameter is a road-closed sign: You can't squeeze through unless you are a sleek, water-molecule-sized sports car, say scientists at the University of Illinois at Urbana-Champaign.

New study points to new treatments for some forms of Lou Gehrig's disease

A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell.

Ground-breaking discoveries that provide hope of an alternative treatment option for haemophilia sufferers

Haemophilia is a hereditary blood disease, primarily affecting males, where the blood fails to clot causing potentially life-threatening 'bleeds'. About one in 6000 Australian males is born with haemophilia in severe, moderate or mild form. People with haemophilia rely on intravenous infusion of recombinant Factor VIII clotting protein.

Vestibular organs provide an on-line movement guidance system

Anyone who's had to find his or her way through a darkened room can appreciate that nonvisual cues play a large role in our sense of movement. What might be less apparent is that not all such cues come from our remaining four senses.

Researchers look at how we understand visual images

The figure is famous: a deceptively simple line drawing that at first glance resembles a vase and, at the next, a pair of human faces in profile. When you look at this figure, your brain must rapidly decide what the various lines denote. Are they the outlines of the vase or the borders of two faces? How does your brain decide?
