Higher thyroid hormone levels associated with artery disease and early death

http://ift.tt/2gZIazF High and high-normal levels of a thyroid hormone called free thyroxine or FT4, were associated with artery disease and death in elderly and middle-aged people.

For older adults with diabetes, losing weight with diet, exercise can improve circulation

http://ift.tt/2zTIYKa Type 2 diabetes affects blood circulation. When blood flow in the brain is impaired, it can affect the way we think and make decisions. Recently, researchers examined information from a 10-year-long study, focusing on whether participants with type 2 diabetes who lowered calories in their diet and increased physical activity had better blood flow to the brain.

Blood flow in the developing heart guides maturation of heart valves

http://ift.tt/2lmls6p Congenital heart valve defects are the most common type of birth defects, the majority of which have no clear genetic cause, suggesting that epigenetic factors play an important role. Now, researchers have found that the shear force of blood flow against the cells lining the early heart valve sends signals for heart ‘cushion’ cells to become fully formed valves.

High-intensity interval training alters brain glucose metabolism in insulin resistant people

http://ift.tt/2iaxtHc Researchers have studied how high-intensity interval training (HIIT) alters the brain’s glucose metabolism in physically inactive insulin resistant people. Only two weeks of HIIT training reduced glucose metabolism in all areas of the brain.
