The influence of government-issued lockdowns during the COVID-19 pandemic on traumatic brain injuries in Tyrol, Austria.

Introduction: In February 2020, COVID-19 infections started to spread in Austria. This was followed by governmental actions and constraints such as lockdowns, quarantine protocols, and a ban on outdoor sports. The goal of this study was to investigate the influence of these measures on the number of traumatic brain injuries (TBI) in the state of Tyrol.

CO Cryo-sorption as a Surface-sensitive Spectroscopic Probe of the Active Site Density of Single-atom Catalysts.

Quantifying the number of active sites is a crucial aspect in the performance evaluation of single metal-atom electrocatalysts. A possible realization is using adsorbing gas molecules that selectively bind to the single-atom transition metal and then probing their surface density using spectroscopic tools. Herein, using in situ X-ray photoelectron (XPS) and near edge X-ray absorption fine structure (NEXAFS) spectroscopy, we detect adsorbed CO gas molecules on a FeNC oxygen reduction single atom catalyst.

Inverted Mattress Knotless Repair of Medial Ulnar Collateral Ligament Avulsion Injury Using Flat Braided Suture Internal Brace.

Direct repair of ulnar collateral ligament (UCL) injuries with suture augmentation has been successful in properly selected patients lacking chronic attritional wear of the medial elbow. Described is a Speed-Fix technique for direct UCL repair using SutureTape, with Brace augmentation. The Speed-Fix repair technique uses an inverted mattress knotless repair with a knotless SwiveLock anchor and FiberTape suture, which allows for theoretical compression at the repair site.

Deciphering the interactome of Ataxin-2 and TDP-43 in iPSC-derived neurons for potential ALS targets.

Ataxin-2 is a protein containing a polyQ extension and intermediate length of polyQ extensions increases the risk of Amyotrophic Lateral Sclerosis (ALS). Down-regulation of Ataxin-2 has been shown to mitigate TDP-43 proteinopathy in ALS models. To identify alternative therapeutic targets that can mitigate TDP-43 toxicity, we examined the interaction between Ataxin-2 and TDP-43.

Effects of Substrate Temperature on Optical, Structural, and Surface Properties of Metal-Organic Vapor Phase Epitaxy-Grown MgZnO Films.

MgZnO possesses a tunable bandgap and can be prepared at relatively low temperatures, making it suitable for developing optoelectronic devices. MgZnO (~0.1) films were grown on sapphire by metal-organic vapor phase epitaxy under different substrate-growth temperatures of 350-650 °C and studied by multiple characterization technologies like X-ray diffraction (XRD), spectroscopic ellipsometry (SE), Raman scattering, extended X-ray absorption fine structure (EXAFS), and first-principle calculations.
