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.

Nighttime dying linked to sleep apnea from brain cell loss

Aim to grow old and die peacefully in your sleep? Be careful what you wish for. A new UCLA study suggests that some people die in their sleep because they stop breathing due to a cumulative loss of cells in the brain's breathing command-post. The online edition of Nature Neuroscience reports the findings.

Australian researchers have found a toxin that plays an important role in the progression of Alzheimer's disease

The research, which is led by two University of New South Wales academics, is significant because drugs that are in the advanced developmental phase for other conditions might be able to be used on Alzheimer's patients, to halt the disease progressing.

Early warning aigns of Alzheimer's show up across cognitive areas years before official diagnosis

By combing through dozens of Alzheimer's disease (AD) studies, psychologists have gained a clear picture of cognitive problems in people who will develop the degenerative brain disease.

Obese people are less likely to receive preventive services such as mammograms, Pap smears and flu shots

The Duke study showed that, for a sample of white middle-aged women, as body mass index (BMI) went up, the odds of receiving mammograms and Pap smears went down.

Scientist have found an unexpected effect of the interaction of PTEN and p53 genes in early stage prostate cancer

Prostate cancer, the second leading cause of cancer death for men in the United States, is caused by changes in several tummor suppressor genes including PTEN and p53. Up to 70 percent of men with prostate cancer have lost one copy of the PTEN gene at the time of diagnosis, and p53 is absent in a high number of patients with advanced prostate cancer.

Obesity's effects on mortality may have been over-estimated

New research shows that obese adults who reach the age of 70 are at no greater risk of dying than their non-obese counterparts, but they do have a much greater probability of spending their remaining years disabled. The data supporting this is reported in the August 2005 issue of The Gerontologist (Vol. 45, No. 4).

Signs of atherosclerosis seen in apparently healthy young adults

Young adults who seem to be healthy, but have a clustering of heart disease risks factors known as metabolic syndrome, tend to have signs of thickening of their carotid artery walls, which is an early indication of atherosclerosis, according to a new study in the Aug 2, 2005, issue of the Journal of the American College of Cardiology.

Aging profile of the human brain differs greatly from that seen in chimpanzees

Researchers have found that the two primary areas of the human brain appear to age in radically different ways: The cortex used in higher-level thought undergoes more extensive changes with age than the cerebellum, which regulates basic processes such as heartbeat, breathing and balance.

Aging and gene expression in the primate brain

While medical science and a healthy lifestyle can help increase life expectancy, many aspects of aging and longevity are beyond our control. Published this week in the open-access journal PLoS Biology, Michael Eisen and colleagues shed light on these genetic factors by identifying sets of genes whose expression changes with age in human and chimp brains.

People have signs of Alzheimer's years before diagnosis

Psychologists say that after examining dozens of Alzheimer's studies, they now have a clear picture of the cognitive problems which will develop in people with the degenerative brain disease.

U.S. beaches getting dirtier and some are disappearing

The National Resources Defense Council (NRDC) has said this week that more and more U.S. beaches are being closed due to contamination, partly because there is more pollution and partly because of better monitoring.

Discovery sheds light on how a low-calorie diet extends lifespan

Mice, rats, worms, flies, and yeast all live longer on a low-calorie diet, which also seems to protect mammals against cancer and other aging-related diseases.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

New breakthrough on the origins of Alzheimer's disease

Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) associated with the University of Antwerp have achieved a new breakthrough in their research on the origins of Alzheimer's disease.

Controlling high blood pressure in individuals age 80 years and older has become a major national health problem

The study found that almost three fourths of those 80 years and older have hypertension -- blood pressure greater than 140 systolic over greater than 90 diastolic. Fewer than 10 percent have "normal" blood pressure levels -- less than 120 systolic over less than 80 diastolic.
