Insulin is a hormone that decreases blood glucose levels. The only cells that produce insulin are pancreatic beta cells (β-cells), and a decrease in these cells is a major cause of diabetes. Although therapies aimed at increasing pancreatic β-cells are eagerly awaited, a strategy that can increase β-cells has, thus far, not been developed. In a promising development, a … [Read more...]

Cold Weather may Pose Challenges to Treating High Blood Pressure
According to the American Heart Association's 2023 Statistical Update, nearly half of adults in the U.S. have high blood pressure. Previous research found that blood pressure varies with the seasons of the year. Most of this variation is in systolic blood pressure -- the top number in a blood pressure reading that gauges the pressure in/against blood vessels during heartbeats. … [Read more...]
Women with PCOS on Keto Diet may see Improvements in Fertility
The ketogenic (keto) diet may lower testosterone levels in women with polycystic ovary syndrome (PCOS), according to a new paper published in the Journal of the Endocrine Society.
