Many congestive HF-associated physiological changes were also suppressed, but the mechanisms aren’t known; level of exercise is critical but results come despite antecedent hypertension
A classic clinical dilemma faces doctors treating patients with congestive heart failure (CHF): while exercise generally protects the normal heart from cardiovascular disease, will exercise potentially "improve the prognosis of patents with CHF, or (will it place) a further excessive demand on an already over-stressed myocardium"?
Thats how a new research paper poses the question, and its positive but still tentative results show: "Briefly we found that low intensity exercise training markedly delayed the onset of overt CHF without a reduction in antecedent hypertension. Additionally, we found that some, but not all, of the classic cellular and systemic physiological alterations normally associated with the development of overt CHF were attenuated with exercise training."

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...
