Higher levels of free thyroxine associated with increased risk of mortality

thyroid hormone
In a report presented at the Endocrine Society meeting, researchers have found that higher levels of free thyroxine in elderly euthyroid men are associated with an increased risk of all- cause mortality. It is already a known fact that thyroid disease and subclinical thyroid function are linked with increased mortality. But this is for the first time that the researchers tried to explore the relationship between thyroid hormones and mortality in men with normal thyroid functions. For their...

Elderly Patients with Metabolic Syndrome more likely to Develop CKD

Although the development of chronic kidney disease (CKD) has been found to be related to the presence of metabolic syndrome in middle age, there was no such study in the elderly people which could establish a similar link. However, according to a latest study, published in the journal Clinical Endocrinology and Metabolism, elderly patients, suffering from high insulin resistance, have been found to be more predisposed to developing a rapid loss of renal function whereas elderly patients...

Enzyme Controlling Ageing Process in Yeast Identified

  Scientists working at John Hopkins Institute, along with researchers from National Taiwan University, have identified a protein in the yeast cells which is responsible for controlling its life span. This particular protein is found in young yeast cells but decreases as the age of the yeast cell advances. Removing the protein from the cell shortens its life span, whereas replacing it extends the life of the cell. Thus, the life span of the yeast cell can be manipulated.   The...
