Bifunctional catalytic activity of anion-doped LaSrCoO for oxygen reduction and evolution reactions.

Here, we synthesized Co-based, anion-incorporated‍ ‌R‌u‌d‌d‌l‌e‌s-d‌e‌n‌-‌Popper perovskite electrocatalysts (LaSrCoO X ) and compared their catalytic performances in the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The ORR mechanism with the newly synthesized F-doped LaSrCoO catalyst was dominated by a four-electron process, and the number of electrons involved in the reaction increased compared with that for LaSrCoO. The OER activity of the hydride-doped LaSrCoO catalyst was the highest among the LaSrCoO system catalysts.

Association of Periodontal Status, Number of Teeth, and Obesity: A Cross-Sectional Study in Japan.

Recent reports have shown an association between obesity and periodontitis, but the precise relationship between these conditions has yet to be clarified. The purpose of this study was to compare the status of periodontitis, tooth loss, and obesity. Participants comprised 235 patients at the Center for Medical and Dental Collaboration in Kanagawa Dental University Hospital between 2018 and 2020.

The RNA-binding protein Cpeb4 is a novel positive regulator of osteoclast differentiation.

Cytoplasmic polyadenylation element binding (CPEB) proteins are RNA-binding proteins involved in translational regulation of the specific target mRNAs and control function of various organs including brain, liver and hematopoietic system. However, the role of CPEB proteins during osteoclast differentiation remains unclear. Here we show that Cpeb4 is required for RANKL-induced osteoclast differentiation in mouse macrophage-derived RAW264.

Design and feasibility assessment of topically applied drug formulations for electroporation.

Few studies have been reported on the design of topical formulations consisting of electrodes and active drugs for electroporation as a means to increase skin permeability of the drugs, although many studies were reported for the effect of this physical means using aqueous drug solutions. We, therefore, designed a prototypic reservoir and matrix topical formulations that are suitable for electroporation in the present study. Plate-plate Ag electrodes and sodium diclofenac were used as model electrodes and the drug, respectively.

Clinical study of acute low-tone sensorineural hearing loss: survey and analysis of glycerol test and orthostatic test.

Fifty patients (14 men and 36 women ranging in age from 16 to 66 years) with acute low-tone sensorineural hearing loss (ALHL) were retrospectively analyzed in this study. The glycerol test and the orthostatic test were performed. On the glycerol test, 43.
