Flow cytometric assays of viable boar sperm were developed to measure reactive oxygen species (ROS) formation (oxidization of hydroethidine to ethidium), membrane lipid peroxidation (oxidation of lipophilic probe C(11)-BODIPY(581/591)), and mitochondrial inner transmembrane potential (DeltaPsi(m); aggregation of mitochondrial probe JC-1) during hypothermic liquid storage and freeze-thawing of b...

Short-Cannel MoS2 Transistors Yi Yang, He Tian, Xing Wu, Tian-Ling Ren, and colleagues demonstrate a photolithography resolution-independent method to realize 10 nm short-channel transistors in article 2100543. By depositing the noble electrode partially on self-oxidized aluminum electrode, channel length is directly defined by ≈10 thickness of oxidization layer, which can provide new opportuni...

It is wise to mimic a bioinspired system design nanoreactor as catalyst containing multiple components for cascade reaction. Here, we report the uniform growth of well-dispersed nano-scale ZIF-8 crystals on pore walls 3DOM TiO2 via TEA-assisted crystallization process. The UV-vis spectra indicate that photosensitizer can extend visible-light absorption TiO2. obtained efficiently catalyze one-po...

Peroxide operon regulator (PerR) is a broadly conserved hydrogen peroxide sensor in bacteria, and oxidation of PerR at its regulatory metal-binding site is considered irreversible. Here, we tested whether this oxidation specifically targets PerR for proteolysis. We find that oxidizing conditions stimulate PerR degradation in vivo, and LonA is the principal AAA+ (ATPases associated with diverse ...

Optical properties of refractory intermetallic thin films Au3Zr were experimentally investigated for the first time, which show distinctive plasmonic in visible and near infrared region. The fabricated through DC magnetron sputtering at various deposition temperature ranging from room to 427 °C annealed different vacuum levels. Both structural optical are found be critically dependent on anneal...

A novel Cr-alloyed medium-Mn steel was designed and manufactured for the hot forming application in automobile. Compared to typical press hardening (PHS) grade of 22MnB5, it possesses more excellent mechanical combination enormously reduced oxidization after hardening. The synchrotron-based high-energy X-ray diffraction experiment indicated that solute C atoms could be partitioned from martensi...

Hyperlipidemia is a major independent risk factor for atherosclerosis. Seeking natural compounds in medicinal plants capable of reducing blood fat and studying their mechanisms of action has been the focus of research in recent years. The aim of the present study was to analyze the mechanisms of apigenin in regulating cholesterol metabolism and protecting blood vessels, and to provide a theoret...
