Memory loss associated with Alzheimer’s reversed: Small trial succeeds using systems approach to memory disorders

Memory loss associated with Alzheimer’s reversed: Small trial succeeds using systems approach to memory disorders

Patient one had two years of progressive memory loss. She was considering quitting her job, which involved analyzing data and writing reports, she got disoriented driving, and mixed up the names of her pets. Continue reading

Scientists identify which genes are active in muscles of men, women

Scientists identify which genes are active in muscles of men, women

If you want your doctor to know what goes wrong with your muscles because of age, disease or injury, it’s a good idea to know what “normal” actually is. Continue reading

Spastic paraplegia: New light shed on cause

Spastic paraplegia: New light shed on cause

Scientists at The Scripps Research Institute (TSRI) have discovered that a gene mutation linked to hereditary spastic paraplegia, a disabling neurological disorder, interferes with the normal breakdown of triglyceride fat molecules in the brain. The TSRI researchers found large droplets of triglycerides within the neurons of mice modeling the disease. The findings, reported this week online ahead of print by the journal Proceedings of the National Academy of Sciences , point the way to potential therapies and showcase an investigative strategy that should be useful in determining the biochemical causes of other genetic illnesses.

Yoga, meditation may help train brain to help people control computers with their mind

Yoga, meditation may help train brain to help people control computers with their mind

New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases Continue reading

How physical exercise protects the brain from stress-induced depression

How physical exercise protects the brain from stress-induced depression

Physical exercise has many beneficial effects on human health, including the protection from stress-induced depression. However, until now the mechanisms that mediate this protective effect have been unknown Continue reading

Cardiorespiratory fitness is often misdiagnosed

Cardiorespiratory fitness is often misdiagnosed

A recent study by the University of Eastern Finland shows that scaling maximal oxygen uptake and maximal workload by body weight confounds measures of cardiorespiratory fitness. It has been a common practice in exercise testing to scale the results by body weight and, according to researchers, this practice should be abandoned. More reliable data on cardiorespiratory fitness can be observed by using lean mass proportional measures Continue reading

Complexity of diabetes: Restoring the complexity of the overall blood sugar control system

Complexity of diabetes: Restoring the complexity of the overall blood sugar control system

For millions of people in the United States living with Type 1 or Type 2 diabetes, measuring the daily rise and fall of blood glucose (sugar) is a way of life. Our body’s energy is primarily governed by glucose in the blood, and blood sugar itself is exquisitely controlled by a complicated set of network interactions involving cells, tissues, organs and hormones that have evolved to keep the glucose on a relatively even keel, pumping it up when it falls too low or knocking it down when it goes too high.

New guidelines issued for managing peri- and postoperative atrial fibrillation

The American Association for Thoracic Surgery (AATS) has released new evidence-based guidelines for the prevention and treatment of perioperative and postoperative atrial fibrillation (POAF) and flutter for thoracic surgical procedures. The guidelines are published in The Journal of Thoracic and Cardiovascular Surgery Continue reading

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Exercise boosts tumor-fighting ability of chemotherapy, team finds

Study after study has proven it true: exercise is good for you. But new research from University of Pennsylvania scientists suggests that exercise may have an added benefit for cancer patients undergoing chemotherapy. Their work, performed in a mouse model of melanoma, found that combining exercise with chemotherapy shrunk tumors more than chemotherapy alone. Continue reading
