Resveratrol prolongs lifespan and delays onset of aging-related traits in a short-lived vertebrate
By studying a particularly short-lived fish species, researchers have been able to show that a natural compound previously shown to extend lifespan in non-vertebrate organisms can also do so in at least one vertebrate species. The findings, reported by Alessandro Cellerino of the Scuola Normale Superiore, Pisa, and colleagues, support the potential utility of the compound in human aging research....Matrilin-3 gene discovered to prevent onset of osteoarthritis
A gene that is associated with osteoarthritis and skeletal deformities in people has been shown to be responsible for preventing the onset of osteoarthritis in adult mice, according to a recent study led by Rhode Island Hospital. The matrilin-3 gene plays a role in early bone development, controls bone mineral density in adulthood and prevents osteoarthritis later in life. Mutations in m...Gene therapy prevents the onset of diabetic symptoms in mice
Acid rain, the environmental consequence of burning fossil fuels, running factories and driving cars, has altered soils and reduced the number of sugar maple trees growing in the Northeast, according to a new study led by Cornell University researchers. The sugar maple is the most economically valuable tree species in the eastern United States because of its high-priced lumber, syrup and...Temperament linked to onset of cancer and early death in female rats
Female rats that are apprehensive of new experiences as infants maintain that temperament and die earlier from mammary and pituitary tumors than do their more adventuresome sisters, according to new research by a team based at the University of Chicago. The apprehensive rats were more likely to have irregular reproductive cycles than adventuresome rats, and that disruption could account fo...Canadian study shows bilingualism has protective effect in delaying onset of dementia by four years
Canadian scientists have found astonishing evidence that the lifelong use of two languages can help delay the onset of dementia symptoms by four years compared to people who are monolingual. There has been much interest and growing scientific literature examining how lifestyle factors such as physical activity, education and social engagement may help build "cognitive reserve" in later yea...Depressed women show signs of earlier onset of Perimenopause
Perimenopause, defined as the time period immediately prior to menopause beginning with normal, biological, and clinical changes and ending a year after the last menstrual periods, is a time of increased vulnerability to depression, especially for women with a history of mood// disorders. Earlier studies have shown that women who experienced menopause before 47 years of age (considered early) wer...Drug to Prevent the Onset of Arthritis
Arthritis is a common health problem worldwide. Both osteoarthritis and rheumatoid arthritis cause joint pain and //stiffness in patients. There is no cure for arthritis and no effective treatment to repair damaged cartilage. A new study could help lead doctors towards a drug to prevent the onset of arthritis. The research pinpoints the molecular pathway and an enzyme that play a pivota...Onset Linked To Severity of Asthma
The age a person develops asthma may help explain their disease more clearly. A new study finds people who are diagnosed with asthma as children // have a different disease than those who develop it as an adult. Researchers say the patients suffered different symptoms and disease progression based on the age of onset. Eighty patients with severe asthma that could not be controlled by st...Lifestyle changes Can Delay the Onset Of Dementia
More than 700,000 strokes occur each year in the United States. Investigators have been tracking the health of men and women for // more than 50 years to see how various factors might impact their risk for heart disease and stroke. In this sub-study, researchers compared the rate of dementia in those with and without a history of stroke.About 20 percent of the people who had a stroke developed de...Lifestyle changes Can Delay the Onset Of Dementia
