R Ali, M Walther, R Bodmeier
The objective of this work was the preparation of osmotic tablets using polymer blends of cellulose acetate butyrate (CAB) or ethylcellulose with ammonio methacrylate copolymer (Eudragit® RL). The advantage of these coatings in comparison to the traditionally used cellulose acetate is their solubility in safer organic solvents like ethanol. Polymer films were characterized with respect to their water uptake, dry mass loss, and mechanical properties. The effect of the polymer blend ratio on drug release and on the rupture force of the coating was investigated...

Based on the superior chemical and thermal stability of hexagonal boron nitride (h-BN), we design and synthesize h-BN supported mesoSiO2-confined Ni catalysts with a stable architecture. The as-prepared catalyst exhibits excellent coke- and sintering-resistance performance in the dry reforming of methane, and especially, there is almost no loss of activity even after a 100 h stability test due to the synergistic effects of the h-BN interface and Ni nanoparticles.

Familiarity with congenital heart disease (CHD) and its manifestations in adults is becoming increasingly important for the practicing cardiothoracic imager. The use of computed tomographic angiography is becoming commonplace not only in adults with a history and subsequent interventions for CHD as a child but also in de novo detection of-typically-milder, survivable forms of CHD, which are clinically suspected because of declining cardiac performance, cardiac events, or murmurs. Occasionally, adult CHD (ACHD) is found incidentally on scans performed for other indications (eg, trauma or neoplasm staging) because of improvements in computed tomographic technology and advanced visualization...

BACKGROUND: Abdominal aortic aneurysm surgery with suprarenal cross-clamping is often associated with renal injury. Although the mechanism underlying such injury is unclear, tissue ischemia and reperfusion, which induces endothelial dysfunction and decreases the availability of tetrahydrobiopterin (BH4), may play a role. We evaluated whether BH4 administration prevents renal ischemia/reperfusion injury in an animal model of aortic cross-clamping. METHODS: Nineteen anesthetized, mechanically ventilated, and invasively monitored adult sheep were randomized into 3 groups: sham animals (n = 5) that underwent surgical preparation but no aortic clamping; an ischemia/reperfusion group (n = 7), where the aorta was clamped above the renal arteries for 1 hour, and a BH4 group (n = 7), in which animals received 20 mg/kg of BH4 followed by aortic cross-clamp for 1 hour...

Wind energy has rapidly become an important alternative among renewable energies, and it is generally considered clean. However, little is known about its impact at the level of ecological communities, especially in biodiversity hotspots. The Isthmus of Tehuantepec is a highly biodiverse region in Mesoamerica, and has the highest potential for generating wind energy in Mexico. To assess the effects of installing a wind farm on the understory bat community in a landscape of fragmented habitat, we assessed its diversity and composition over four stages of installation (site preparation, construction, and two stages of operation)...
