GM-CSF protein reduces AD pathology, reverses memory loss: Study

A signaling protein released during rheumatoid arthritis dramatically reduced Alzheimer's disease pathology and reversed the memory impairment of mice bred to develop symptoms of the neurodegenerative disease, a new study by the University of South Florida reports. Researchers found that the protein, GM-CSF, likely stimulates the body's natural scavenger cells to attack and remove Alzheimer's amyloid deposits in the brain.

NCF announces formal disease model for Chronic Fatigue Syndrome

The National CFIDS Foundation Inc., of Needham Mass, has announced its formal disease model for Chronic Fatigue Syndrome (CFS) also known as Chronic Fatigue Immune Dysfunction Syndrome (CFIDS) as well as Myalgic Encephalomyelitis (ME). According to the NCF, a subgroup of patients with CFS fit a unique disease profile based on a model for a radioactive toxin.

Study supports role for SNARK protein in regulating glucose transport during muscle contraction and exercise

Skeletal muscles combust both lipids and carbohydrates during exercise. The carbohydrates consist of both glycogen stored in the muscles as well as glucose extracted from the blood. Being a major sink for glucose disposal, skeletal muscle represents an important model tissue for studying the intracellular signaling pathways leading to increased glucose transport.

Oxytocin level associated with parent-specific styles of interaction: Research

The hormone oxytocin has come under intensive study in light of emerging evidence that its release contributes to the social bonding that occurs between lovers, friends, and colleagues. Oxytocin also plays an important role in birth and maternal behavior, but until now, research had never addressed the involvement of oxytocin in the transition to fatherhood.

Researchers develop tiny color-changing sensor molecules

A new approach to building an "artificial nose" using fluorescent compounds and DNA could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.

Study finds genetic change in chromosome 4 causes FSHD

The Muscular Dystrophy Association today heralds a landmark muscular dystrophy advance by an international study team of scientists and physicians from the Netherlands, United States, France and Spain. Led by MDA-grantee Silvère van der Maarel, Ph.D., at Leiden University Medical Center in the Netherlands, the collaborative study of more than 2,300 people found that two distinct genetic changes on chromosome 4 must be present to cause facioscapulohumeral muscular dystrophy (FSHD).

New squeeze test for screening potential drugs for Alzheimer's

Brain cells exposed to a form of the amyloid beta protein, the molecule linked to Alzheimer's disease, become stiffer and bend less under pressure, researchers at UC Davis have found. The results reveal one mechanism by which the amyloid protein damages the brain, a finding that could lead to new ways to screen drugs for Alzheimer's and similar diseases.

Combination of 2 FDA approved drugs eliminate HIV infection

Researchers at the University of Minnesota Academic Health Center have identified two drugs that, when combined, may serve as an effective treatment for HIV.

'Rotten eggs' gas inside knee joint protects against inflammation

Hydrogen sulfide (H2S) is a gas more commonly associated with the smell of 'rotten eggs' and blocked drains. However, it has now been shown to be present naturally in our bodies and reside in knee joint synovial fluid, the protective fluid found in the cavities of joints that reduces friction between the cartilage of joints during movement. Synovial fluid H2S may play a role in reducing inflammation in joints.

FSH society applauds findings of facioscapulohumeral muscular dystrophy

This is what we have all been working towards and fighting for, says Daniel Paul Perez, co-founder, president and CEO of the FSH Society and a 48-year-old patient with facioscapulohumeral muscular dystrophy (FSHD), applauding the researchers whose study on yesterday's ScienceXpress, the journal Science's online advanced edition, pinpoints for the first time the exact genetic mechanism triggering FSHD, the most common muscular dystrophy.

Dilation of blood vessels restores muscle synthesis in elderly

University of Texas Medical Branch at Galveston researchers believe they've found a way to use widely available blood pressure drugs to fight the muscular weakness that normally accompanies aging.

Causes and consequences of increased adiposity and decreased muscle and bone mass

Increased adiposity and decreased muscle mass contribute substantially to age-dependent disease and disability. In particular age-related increase in adiposity is quickly becoming a major threat to public health throughout the world. Although the hypothesis that age-related changes in body composition are due to lifestyle choices alone is well accepted, it is a vast oversimplification.

Research on ocean-dwelling bacterium unveils food poisoning mechanism in human

Researchers at UT Southwestern Medical Center have uncovered a key weapon in the molecular arsenal the infectious bacterium Vibrio parahaemolyticus (V. para) uses to kill cells and cause food poisoning in its human host.

Cell-depleted lung used as natural growth matrix for generating new rat lung from embryonic stem cells

The first successful report of using cell-depleted lung as a natural growth matrix for generating new rat lung from embryonic stem cells is presented in a breakthrough article in Tissue Engineering, Part A, a peer-reviewed journal published by Mary Ann Liebert, Inc..

Study demonstrates association between yoga postures, increased GABA levels and decreased anxiety

Researchers from Boston University School of Medicine (BUSM) have found that yoga may be superior to other forms of exercise in its positive effect on mood and anxiety. The findings, which currently appear on-line at Journal of Alternative and Complementary Medicine, is the first to demonstrate an association between yoga postures, increased GABA levels and decreased anxiety.

New research could extend the life of donated organs

The fruit fly Drosophila melanogaster does boast a powerful genetic system making it an ideal organism to test a cool new discovery: how an enzyme regulates body energy levels. Shutting off this molecular thermostat could result in a newfound cold tolerance that has multiple applications, including extending the 24-hour window donated organs now have for optimum use.

Human neural stem cells restore motor function in mice with chronic spinal cord injury

StemCells, Inc. announced today the publication of new preclinical data demonstrating that the Company's proprietary human neural stem cells restore lost motor function in mice with chronic spinal cord injury. This is the first published study to show that human neural stem cells can restore mobility even when administered at time points beyond the acute phase of trauma, suggesting the prospect of treating a much broader population of injured patients than previously demonstrated.

Research finds increased diagnostic activity among men with family history of prostate cancer

The brothers of men with prostate cancer are at an increased risk of prostate cancer diagnosis because of increased diagnostic activity and not necessarily because they carry a genetic mutation that increases risk of the disease, according to a study published online August 19 in The Journal of the National Cancer Institute.

Genetic architecture controlling growth of 'back-up' blood vessels uncovered

Researchers at the University of North Carolina at Chapel Hill School of Medicine have uncovered the genetic architecture controlling the growth of the collateral circulation - the "back-up" blood vessels that can provide oxygen to starved tissues in the event of a heart attack or stroke.

ISCO to formalize eye care based stem cell therapeutic programs into Cytovis business unit

International Stem Cell Corporation, today announced that its stem cell therapeutic programs focused on protective, transparent corneas (CytoCor™) in the front of the eye and the light-sensitive retinal tissue (CytoRet™) in the back of the eye will be formalized into a new business unit, Cytovis™.
