Stem cells with heart bypass surgery trial to begin

The University of Pittsburgh Medical Center (UPMC) has been granted approval by the U.S. Food and Drug Administration (FDA) to conduct a clinical trial to determine the safety and feasibility of injecting a patient's own bone marrow-derived stem cells directly into the heart during conventional heart bypass surgery.

Acupuncture relieves symptoms of fibromyalgia

Fibromyalgia patients treated with six sessions of acupuncture experienced significant symptomatic improvement compared to a group given simulated acupuncture sessions according to a new Mayo Clinic study.

Using muscle tissue from tarantulas scientists discover how muscles relax

Using muscle tissue from tarantulas, an HHMI international research scholar and his colleagues have figured out the detailed structure and arrangement of the miniature molecular motors that control movement.

Brain can be tricked into thinking the pain has gone

A new U.S. study has found that it is possible that by just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations.

First direct evidence that endorphins play a role in the phenomenon known as the placebo effect

Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations, a new University of Michigan study finds.

Rotenone study may lead to novel therapies for Parkinson's disease

Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control.

MRI helps map smallest deformations inside hearts

Using magnetic resonance imaging technology, or MRI, to tag the work of millions of individual strands of heart muscle fibers, researchers at Johns Hopkins have successfully mapped the smallest deformations inside the beating hearts of 441 middle-aged and elderly men and women who have either silently developed heart disease or remained healthy.

New technique for creating human embryonic stem cells

Researchers have developed a new technique for creating human embryonic stem cells by fusing adult somatic cells with embryonic stem cells. The fusion causes the adult cells to undergo genetic reprogramming, which results in cells that have the developmental characteristics of human embryonic stem cells.

Japanese encephalitis in Indian province - update

Health officials say nine more people have now died from Japanese encephalitis in India's Uttar Pradesh state, taking the death toll from the mosquito-borne disease to 99.

Protein Sirt1 points to new therapies for type 2 diabetes

Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study appears in the August 17 issue of Cell Metabolism.

Adult stem cells may play a role in the development of some forms of cancer

Researchers at UT Southwestern Medical Center have determined that stem cells in a certain region of the brain may be the source of a particular type of incurable brain tumor and may be implicated in other types of brain cancers as well.

Decline in energy production by mitochondria appears to be a key problem leading to insulin resistance

A detectable decline in energy production by mitochondria - the organelles that are the cell's furnace for energy production - seems to be a key problem leading to insulin resistance, and thus to type 2 diabetes, according to studies by Howard Hughes Medical Institute researchers.

Gene therapy success for the treatment of congenital muscular dystrophy (CMD) in mice

Researchers from the University of Pittsburgh report the first study to achieve success with gene therapy for the treatment of congenital muscular dystrophy (CMD) in mice, demonstrating that the formidable scientific challenges that have cast doubt on gene therapy ever being feasible for children with muscular dystrophy can be overcome.

Body's own defense mechanism causes some of the most serious asthma symptoms

McGill University Health Centre (MUHC) scientists have discovered that our body's own defense mechanism causes some of the most serious asthma symptoms.

Genes interact with behavior to affect how well people move

Genes can keep elderly people from benefiting equally from exercise, no matter how much effort they expend, according to research findings published in today's (Aug. 10) Journal of the American Medical Association.

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.

Snorers can blame the shape of their throats

Scientists have discovered, by carrying out head and neck scans of snorers and non-snorers, why it is that some people are chronic snorers.

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.

Experts predict that bone fractures will become a bigger and more costly problem

With an aging population, and with people living longer, experts say bone fractures will become a bigger and more costly problem unless more is done to prevent them.

Enzyme involved in blood pressure regulation may also influence how the body responds to exercise

New research suggests why some older adults who exercise have better physical function than others. Surprisingly, researchers found that an enzyme involved in blood pressure regulation may also influence how the body responds to exercise.
