BACKGROUND Exercise training has beneficial effects in patients with heart failure, although there is still no clear evidence that it may impact on their survival. There are no data regarding the effects of exercise in subjects with chronic left ventricular (LV) volume overload. Using a rat model of severe aortic valve regurgitation (AR), we studied the effects of long-term exercise training on...

The preservation of beam quality along the UNILAC Alvarez DTL section is a major concern with respect to the availability of the design beam parameters for FAIR. The DTL comprises 177 accelerating gaps and 184 quadrupoles for transverse beam focusing. They form a periodic structure of linear elements. The high beam currents needed for FAIR arise non-linear space forces leading to emittance grow...

ABSTRACT Background: Sacral-alar-iliac (SAI) screws are increasingly used for lumbo-pelvic fixation procedures. Insertion of SAI is technically challenging, and surgeons often rely on costly time-consuming navigation systems. We investigated the accuracy precision an augmented reality (AR)–based commercially available head-mounted device requiring minimal infrastructure. M...

Quantitative constraints on the ages of melt-forming impact events on the Moon are based primarily on isotope geochronology of returned samples. However, interpreting the results of such studies can often be difficult because the provenance region of any sample returned from the lunar surface may have experienced multiple impact events over the course of billions of years of bombardment. We ill...

Modification of aldose reductase (AR) by the nitrosothiols S-nitroso-N-acetyl penicillamine (SNAP) and N-(beta-glucopyranosyl)-N(2)-acetyl-S-nitrosopenicillamide (glyco-SNAP) resulted in a 3-7-fold increase in its k(cat) and a 25-40-fold increase in its K(m) for glyceraldehyde. In comparison with the native protein, the modified enzyme was less sensitive to inhibition by sorbinil and was not ac...
