Unexpected cell shape change raises possibility of novel therapeutic approach; Further animal study urged before human testing
Not only is low thyroid function very common in congestive heart failure, it also indicates a reduced likelihood of recovery, and an increased chance of death.
But based on earlier work showing that whatever leads to heart failure it is always preceded by changes in the heart cells, a new study demonstrates that a moderate dose of thyroid hormones (TH) over 30 days "normalizes" the shape of the cardiac cells (myocytes) and reduces stress on the hearts wall nearly 40%. "As patients move toward heart failure, the myocytes become longer and flatter, and the wall stress worsens," according to the head of the laboratory where the research was performed. "But moderate TH therapy selectively targeted myocyte cross-sectional shape and modified it in a positive way.
This is the first clue on what might be a novel therapeutic approach to heart failure because of the return to a more normal heart cell shape," according to A. Martin Gerdes, director of the Cardiovascular Research Institute, University of South Dakota.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
