BACKGROUND AND AIMS Hypothermia provides neuroprotection after cardiac arrest, hypoxic-ischemic encephalopathy, and in animal models of ischemic stroke. However, as drug development for stroke has been beset by translational failure, we sought additional evidence that hypothermia protects human neurons against ischemic injury. METHODS Human embryonic stem cells were cultured and differentiate...

BACKGROUND Erectile dysfunction (ED) is a prevalent complication of diabetes, and oxidative stress is an important feature of diabetic ED. Oxidative stress-induced damage plays a pivotal role in the development of tissue alterations. However, the deleterious effects of oxidative stress in the corpus cavernosum with the progression of diabetes remain unclear. The aim of this study was to evaluat...

The pure elements hydrogen, fluorine and oxygen and the mixtures hydrogen-oxygen and hydrogen-fluorine are used in several industrial applications nowadays. Hydrogen might become a renewable energy carries in fuel cell technologies [122, 16]. Hydrogen is considered a fuel which can replace all the major fuels [46, 95]. Consequently, the estimation of thermodynamic data for the mentioned systems...

BACKGROUND The prevention of bovine respiratory disease complex (BRD) in beef cattle is important to maintaining health and productivity of calves in feeding operations. OBJECTIVE Determine whether BRD bacterial and viral pathogens are susceptible to the lactoperoxidase/hydrogen peroxide/iodide (LPO/H2 O2 /I- ) system in vitro and to determine whether the oral administration of sodium iodide ...

Porous dielectric materials provide lower capacitances that reduce RC time delays in integrated circuits. Typical low-k materials include porous SiOCH—silicon dioxide with carbon groups, principally CH3, lining the pores. With a high porosity, internally connected pores provide pathways for reactive species to enter into the material. Fluorocarbon plasmas are often used to etch SiOCH, a process...

Visualization phase perturbations induced by studied medium in a probing multiwave light field performed via polychromatic Foucault-Hilbert transformations combination registration RGB-...

Selective catalytic reduction of NO X by hydrogen (H2-SCR) in the presence of oxygen has been investigated over the NiCo2O4 and Pd-doped NiCo2O4 catalysts under varying conditions. The catalysts were prepared by a sol-gel method in the presence of oxygen within 50-350 °C and were characterized using XRD, BET, EDS, XPS, Raman, H2-TPR, and NH3-TPD analysis. The results demonstrated that the doped...

In this communication we review selected experiments involving the use of carbon paste electrodes (CPEs) to monitor and measure brain tissue O2 levels in awake freely-moving animals. Simultaneous measurements of rCBF were performed using the H2 clearance technique. Voltammetric techniques used include both differential pulse (O2) and constant potential amperometry (rCBF). Mild hypoxia and hyper...

The use of [FeFe]-hydrogenase enzymes for the biotechnological production of H2 or other reduced products has been limited by their sensitivity to oxygen (O2). Here, we apply a PCR-directed approach to determine the distribution, abundance, and diversity of hydA gene fragments along co-varying salinity and O2 gradients in a vertical water column of Great Salt Lake (GSL), UT. The distribution of...
