A successful diet may do more than trim the waistline.
University of Calgary scientists say old-fashioned calorie counting could also be the key to maintaining young muscles as we age.
University of Utah researchers have taken a potentially powerful new therapy for treating diabetes, peripheral vascular disease, and other illnesses out of the test tube and into animals by demonstrating it restores nerve and blood vessel growth in mice.
Despite their celebrated "immortality," the capacity of embryonic stem (ES) cells for endless division has its limits. After a very extended childhood spent dividing in a culture dish, even stem cells tend to grow up and assume adult roles as workaday nerve, muscle, or blood cells, never to return to their youthful state.
Scientists at Whitehead Institute, in collaboration with colleagues at several research centers, have identified a key biological pathway that, when obstructed, causes Parkinson's symptoms. Even more importantly, they have figured out how to repair that pathway and restore normal neurological function in certain animal models.
Only recently discovered, a small protein in the brain known as neuropeptide S has been found to induce both profound wakefulness and a less anxious state in animals, and, according to new research, may represent a novel target for the treatment of psychotic behavior and schizophrenia. Neuropeptide S can reduce the biochemical and behavioral symptoms of schizophrenia in an established animal model for this mental illness that affects some 2 million Americans.
Neurobiologists have known that a novel environment sparks exploration and learning, but very little is known about whether the brain really prefers novelty as such. Rather, the major 'novelty center' of the brain -- called the substantia nigra/ventral tegmental area (SN/VTA) -- might be activated by the unexpectedness of a stimulus, the emotional arousal it causes, or the need to respond behaviorally.
Traveling for more than 4 hours by air, car, bus or train is associated with an increased risk of venous thrombosis. In a large study (the MEGA study) of nearly 2000 people with a first thrombosis in the Netherlands, Dr. Suzanne Cannegieter and colleagues from the Leiden University Medical Center looked at the risk factors for thrombosis compared with their partners, who did not have thrombosis.
For the first time, researchers have enticed transplants of embryonic stem cell-derived motor neurons in the spinal cord to connect with muscles and partially restore function in paralyzed animals. The study suggests that similar techniques may be useful for treating such disorders as spinal cord injury, transverse myelitis, amyotrophic lateral sclerosis (ALS), and spinal muscular atrophy.
A team of researchers led by Prof. Irun Cohen of the Weizmann Institute of Science Immunology Department has revealed the molecular mechanism of a vaccine for Type 1 diabetes. The new findings should help amplify the effectiveness of the vaccine, which is currently in advanced stages of clinical trials.
He is a quack. A kook. A huckster. The medical world looks at Ronald Klatz, the man who started the anti-aging medicine industry, and sees nothing more than a brilliant businessman who made hay off vulnerability and na
