[Noninvasive magnetic stimulation with endoscopic navigation for the treatment of cricopharyngeal failure in chronic critical illness].

Objective: To assess the efficacy of treatment of cricopharyngeal insufficiency in chronic critical illness caused by severe brain injury using non-invasive magnetic stimulation with endoscopic navigation.

Material And Methods: Thirty patients (19 men and 11 women, mean age 50±12 years) were studied. The exposure was carried out by a bipolar alternating magnetic field using an inductor located in the projection of the hyoid bone.

NHF-Induced Morphology Control of CoP Nanostructures to Enhance the Hydrogen Evolution Reaction.

Developing non-noble metal catalysts with superior catalytic activity and excellent durability is critically essential to promote electrochemical water splitting for hydrogen production. Morphology control as a promising and effective strategy is widely implemented to change the surface atomic coordination and thus enhance the intrinsic catalytic performance of current electrocatalysts. Herein, a series of cobalt phosphide (CoP) electrocatalysts with tunable morphologies of nanosheets, nanowires, nanorods, and nanoblocks have been prepared for the enhanced hydrogen evolution reaction (HER) by only adjusting the amount of ammonium fluoride (NHF) in the hydrothermal process.

MoS@ZnO Nanoheterostructures Prepared by Electrospark Erosion for Photocatalytic Applications.

MoS@ZnO nanoheterostructures were synthesized by electrospark erosion of zinc granules in a hydrogen peroxide solution and simultaneous addition of MoS nanostructured powder into the reaction zone. The morphology, size of the crystallites, as well as elemental and phase composition of the prepared structures, were examined using transmission electron microscopy and X-ray diffraction analysis. It was found that the synthesized products represent heterostructures containing MoS nanoparticles formed on ZnO nanoparticles.

Thermotropic Liquid Crystal-Assisted Chemical and Biological Sensors.

In this review article, we analyze recent progress in the application of liquid crystal-assisted advanced functional materials for sensing biological and chemical analytes. Multiple research groups demonstrate substantial interest in liquid crystal (LC) sensing platforms, generating an increasing number of scientific articles. We review trends in implementing LC sensing techniques and identify common problems related to the stability and reliability of the sensing materials as well as to experimental set-ups.

Unprovoked deep venous thrombosis in a young adult associated with membranous obstruction of inferior vena cava.

Unprovoked deep venous thrombosis (DVT) in young adults is an unusual phenomenon, but it is associated with significant morbidity. Developmental anomalies of the inferior vena cava (IVC) should be considered as a possible aetiological factor, and appropriate investigations should be performed to determine the conclusive diagnosis and necessary treatment plan. We report a case of spontaneous thrombosis of the IVC and bilateral iliac venous system in a young man, associated with membranous obstruction of the IVC.
