A team of researchers at Massachusetts General Hospital (MGH) reports in the American Journal of Managed Care that virtual video visits, one form of telehealth visit used at the hospital, can successfully replace office visits for many patients without compromising the quality of care and communication.
There is little benefit for those over 70 taking higher dose vitamin D supplements to improve their bone strength and reduce the risk of falls, new research has revealed. Older people are often encouraged to take supplements of vitamin D to keep bones, teeth, and muscles healthy.
More than half of female surgeons in the UK have faced or witnessed discrimination in the workplace, suggest the results of a confidential online poll, published in the online journal BMJ Open.
Here's to sipping a cupful of health: Green tea steeped in bottled water has a more bitter taste, but it has more antioxidants than tea brewed using tap water, according to new Cornell University food science research published in Nutrients.
Lingering inflammation in the colon is a known risk factor for colorectal cancer and now scientists report one way it resets the stage to enable this common and often deadly cancer.
The pharmaceutical industry, in recent years, has been marked by a cycle of outrage from patient groups, insurers and politicians each time a particularly expensive new drug hits the market. The considerable ticket price attached to blockbuster newcomers inevitably draws a widespread public outcry, and, lingering in the media spotlight, are often cited as the most likely culprits driving the skyrocketing drug costs in the United States.
A team of scientists from the New York Stem Cell Foundation Research Institute reported in Stem Cell Research and Therapy that they have made valuable progress toward creating clinical-grade cells for treatment of bone disease and injury. In their study, the team identified two types of growth media that could support effective expansion of mesenchymal progenitor cells from stem cells in a clinically compatible, Good Manufacturing Practice setting. GMP guidelines require that cells to be used as therapies are created without the use of animal-derived substances.
Ketone bodies (acetoacetic acid, beta-hydroxybutyric acid) are metabolites that can be used as energy sources like glucose and fatty acids. They can be converted into acetyl-CoA, which produces energy via the Krebs cycle in the mitochondria, and are typically used as an alternative energy source during starvation, fasting, or periods of high-intensity exercise.
However, their utilization rate in the heart and effect on disease conditions was poorly understood. Researchers have measured the ketone body utilization rate in the heart and confirmed that it decreases when the heart is in a state of reduced blood flow (myocardial ischemia).
