Gut lactobacilli can affect the metabolic functions of healthy humans. We tested whether a 1500 kcal/d diet supplemented with cheese containing the probiotic Lactobacillus plantarum TENSIA (Deutsche Sammlung fur Mikroorganismen, DSM 21380) could reduce some symptoms of metabolic syndrome in Russian adults with obesity and hypertension. In this 3-week, randomized, ...

The first rearrangement of 2-methyleneoxetanes to alpha,beta-unsaturated methylketones is reported. It is proposed that, when these substrates are heated, the corresponding oxetes are formed and subsequently undergo electrocyclic ring-opening. In particular, alpha-silyl-alpha,beta-unsaturated methylketones were isolated in moderate to high yields and with high stereoselectivities. Based on the proposed mechanism, Density ...

The non-deterministic nature of photon sources is a key limitation for single-photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single-photon yield without enhancing the output noise. Here the intrinsic statistical limit of an individual source is surpassed by spatially multiplexing two monolithic silicon-based correlated photon pair sources ...
