Enhanced Photoelectrochemical Property of TiO Nanotube Array Photoanode Deposited with Al,Cr-Codoped SrTiO Nanocubes.

There is a demand for the effective utilization of solar energy with highly functional photoelectrodes for photoelectrochemical (PEC) applications, such as water splitting and CO reduction. TiO nanotube arrays (TNTA) with a large surface area have been studied as potential photoelectrodes mainly due to their strong oxidation potential. However, it has disadvantages of fast charge recombination and little responsivity to visible light.

Fluorescence Discrimination of Pharmacological Effects on the Na-Ca Exchanger and Sarco-Endoplasmic Reticulum Ca-ATPase in Mouse Ventricular Cardiomyocytes.

We developed a method to evaluate the activity of the Na-Ca exchanger (NCX) and sarco-endoplasmic reticulum Ca-ATPase (SERCA) with fluorescence microscopy in mouse ventricular cardiomyocytes. In non-beating ventricular cardiomyocytes, α-adrenoceptor stimulation by phenylephrine caused a decrease in the cytoplasmic Ca concentration, which was inhibited by SEA0400, an NCX inhibitor, but not cyclopiazonic acid, a SERCA inhibitor. β-Adrenoceptor stimulation by isoprenaline caused a decrease in the cytoplasmic Ca concentration, which was inhibited by cyclopiazonic acid but not SEA0400.

Treatment with silver nitrate versus topical steroid treatment for umbilical granuloma: A non-inferiority randomized control trial.

Objective: The aim of this prospective multicenter randomized controlled trial was to compare the efficacy of silver nitrate cauterization against that of topical steroid ointment in the treatment of neonatal umbilical granuloma.

Methods: An open-label, non-inferiority randomized controlled trial was conducted from January 2013 to January 2016. The primary endpoint for the silver nitrate cauterization and topical steroid ointment groups was the healing rate after 2 weeks of treatment, applying a non-inferiority margin of 10%.

Mixed germ cell tumor and hemangioblastoma in the cerebellum: report of a rare coexistence.

We report a case of a cerebellar tumor consisting of a mixed germ cell tumor (GCT) and a hemangioblastoma. A 22-year-old man presented with myoclonus and cerebellar ataxia. Magnetic resonance imaging showed a tumor mass in the left cerebellar hemisphere.
