Visualized Embolization of Inferior Vena Cava Thrombus During the Abdominal Compression Maneuver to Evaluate for a Patent Foramen Ovale.

• IVC compression is an alternative to Valsalva to confirm the presence of a PFO. • A drawback of this method is reduced IVC compression in obese patients. • Use with caution in patients with low cardiac output and gastrointestinal diseases.

Versatile application of BiVO/TiO S-scheme photocatalyst: Photocatalytic CO and Cr(VI) reduction.

Herein, the synthesis, characterization, and reduction properties of 2D TiO aerogel powder decorated with BiVO (TiO/BiVO) were investigated for versatile applications. First, 2D TiO was prepared via lyophilization and subsequently modified with BiVO using a wet impregnation method. The morphology, structure, composition, and optical properties were evaluated using transmission electron microscopy (TEM), X-ray diffractometry (XRD), laser-induced breakdown spectroscopy (LIBS), and diffuse reflectance spectroscopy (DRS), respectively.

Fluoride-free synthesis of anodic TiO nanotube layers: a promising environmentally friendly method for efficient photocatalysts.

TiO nanotube (TNT) layers are generally prepared in fluoride-based electrolytes electrochemical anodization that relies on the field-assisted dissolution of Ti metal forming nanoporous/nanotubular structures. However, the usage of fluoride ions is considered hazardous to the environment. Therefore, we present an environmentally friendly synthesis and application of TNT layers prepared in fluoride-free nitrate-based electrolytes.

Contribution of photocatalytic and Fenton-based processes in nanotwin structured anodic TiO nanotube layers modified by Ce and V.

In the present work, nanotwin structured TiO nanotube (TNT) layers are prepared by the electrochemical anodization technique to form the anatase phase and by surface modification spin-coating of Ce and V precursors to form Ce-TNT and V-TNT, respectively. The surface and cross-sectional images by SEM revealed that the nanotubes have an average diameter of ∼130 nm and a length of ∼14 μm. In addition, the TEM images revealed the nanotwin structures of the nanotubes, especially the anatase (001) and (112) twin surfaces, that increase the transport of photogenerated charges.

Is the mechanism of COVID-19 coagulopathy still a rabbit's hole?

The pathophysiology of COVID-19 is an enigma with its severity often determined by the extent of coagulopathy. Several regulatory pathways targeted by the SARS-CoV-2 include the renin-angiotensin system, von Willebrand Factor, and most importantly, the complement pathway. This article discusses these pathways to help design potential future therapies.
