Selective his bundle pacing eliminates crochetage sign: A case report.

Background: Crochetage sign is a specific electrocardiographic manifestation of ostium secundum atrial septal defects (ASDs), which is associated with the severity of the left-to-right shunt. Herein, we reported a case of selective his bundle pacing (S-HBP) that eliminated crochetage sign in a patient with ostium secundum ASD.

Case Summary: A 77-year-old man was admitted with a 2-year history of chest tightness and shortness of breath.

Tanshinone IIA: a Chinese herbal ingredient for the treatment of atherosclerosis.

Tanshinone IIA (Tan IIA) is a fat-soluble compound extracted from , which has a protective effect against atherosclerosis (AS). Tan IIA can inhibit oxidative stress and inflammatory damage of vascular endothelial cells (VECs) and improve endothelial cell dysfunction. Tan IIA also has a good protective effect on vascular smooth muscle cells (VSMCs).

Efficacy and Safety of Different Dosing Regimens of Colchicine in Patients With Coronary Artery Disease: A Network Meta-analysis of 15 Randomized Controlled Trials.

Several meta-analyses have investigated the effects of different doses of colchicine in treating coronary artery disease, but all dosing regimens were never compared in a single study. We aimed to compare the efficacy and safety of 3 dosing regimens of colchicine in patients with coronary artery disease. PubMed, EMBASE, the Cochrane Library, and SCOPUS were searched for randomized controlled trials involving different colchicine doses.

Electrochemical degradation of ciprofloxacin with a Sb-doped SnO electrode: performance, influencing factors and degradation pathways.

Sb-doped SnO electrodes were prepared with the practical sol-gel method and were used for the electrocatalytic degradation of ciprofloxacin (CIP) in aqueous solution. Results from the electrochemical characterization (including cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy) showed that the electrode with 16 coating times (SSO-16) had the highest oxygen evolution potential of 2.2 V ( SCE) and the highest electrochemically active area of 3.

Synthesis and application of BiWO for the photocatalytic degradation of two typical fluoroquinolones under visible light irradiation.

Bismuth tungstate (BiWO) was successfully synthesized by a method combining ultrasonic solvothermal treatment and high-temperature calcination. The products were affirmed by X-ray diffraction, scanning electron microscopy, UV-vis diffuse reflection spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The characterization results indicated that calcination could improve the crystallinity and visible light utilization capacity of BiWO.

A new method for electrodeposition of Al coatings from ionic liquids on AZ91D Mg alloy in air.

Electrodeposition of Al on Mg alloys from ionic liquids has been achieved scientifically. However, it is difficult to realize industrialized production since the preparation of electroplating bath and electrodeposition process must be carried out under inert atmosphere. A simple and practical method was then proposed to guarantee such manipulations in air by introducing a solid water-adsorbent material as well as a liquid protective film in electroplating bath.
