Brought to light: Ag(2) S-Ag hybrid nanotubes were synthesized by rapid microwave-assisted sulfidation of Ag(2) CO(3) nanorods. The relative amounts of Ag(2) S and Ag in the hybrid structure can be controlled easily by varying the concentration of the sulfur precursor. The optimized Ag(2) S-Ag hybrid structure has superior photocatalytic ...

Although cognitive training usually improves cognitive test performance, the capability to transfer these training gains into respective or functionally related cognitive domains varies significantly. Since most studies demonstrate rather limited transfer effects in older adults, aging might be an important factor in transfer capability differences. This study investigated the transfer ...

Recent work suggests that closely related cerambycid species often share pheromone components, or even produce pheromone blends of identical composition. However, little is known of the pheromones of species in the subfamily Prioninae. During field bioassays in California, males of three species in the prionine genus Tragosoma were attracted to ...

Experimental models of unprovoked atrial tachyarrhythmias (AT) in conscious, ambulatory animals are lacking. We hypothesized that the aging, spontaneously hypertensive rat (SHR) may provide such a model. Baseline ECG recordings were acquired with radiotelemetry in 8 young (14-wk-old) and 8 aging (55-wk-old) SHRs, and in 2 groups of 4 age-matched ...
