Overweight boys have greater increases in blood pressure in response to stress than their female peers and decreased ability to restore normal pressures, researchers say in the November issue of Hypertension.
A Medical College of Georgia study showed that, despite typically having a greater height/weight ratio, overweight girls’ blood pressures respond less to stress and their natural mechanisms for decreasing blood pressure work significantly better, said Dr. Gregory A. Harshfield, principal author.
"What we observed is that the boys had higher levels of blood pressure throughout, including during stress and recovery, but they did not show an equally greater level of sodium excretion to compensate for higher levels of blood pressure during stress," said Dr. Harshfield. "What we are showing is that the mechanisms driving salt-sensitive hypertension are having more impact in males than females," he said, noting that larger studies are needed before reaching any conclusions.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
