Non-invasive brain microcurrent stimulation therapy of long-COVID-19 reduces vascular dysregulation and improves visual and cognitive impairment.

Background: An effective treatment is needed for long-COVID patients which suffer from symptoms of vision and/or cognition impairment such as impaired attention, memory, language comprehension, or fatigue.

Objective: Because COVID-19infection causes reduced blood flow which may cause neuronal inactivation, we explored if neuromodulation with non-invasive brain stimulation using microcurrent (NIBS), known to enhance blood flow and neuronal synchronization, can reduce these symptoms.

Methods: Two female long-COVID patients were treated for 10-13 days with alternating current stimulation of the eyes and brain.

U2O5 Film Preparation via UO2 Deposition by Direct Current Sputtering and Successive Oxidation and Reduction with Atomic Oxygen and Atomic Hydrogen.

We describe a method to produce U2O5 films in situ using the Labstation, a modular machine developed at JRC Karlsruhe. The Labstation, an essential part of the Properties of Actinides under Extreme Conditions laboratory (PAMEC), allows the preparation of films and studies of sample surfaces using surface analytical techniques such as X-ray and ultra-violet photoemission spectroscopy (XPS and UPS, respectively). All studies are made in situ, and the films, transferred under ultra-high vacuum from their preparation to an analyses chamber, are never in contact with the atmosphere.

Crystal Structure and Magnetic Properties of Uranium Hydride UH Stabilized as a Thin Film.

A new type of uranium binary hydride, UH, with the CaF crystal structure, was synthesized in a thin-film form using reactive sputter deposition at low temperatures. The material has a grain size of 50-100 nm. The lattice parameter a = (535.

Influence of physician evaluation portals on orthodontist selection by patients.

Objective: This survey aimed to determine the influence of physician evaluation portals (PEP) on a patient's choice of physicians, particularly orthodontists.

Materials And Methods: Questionnaires were used to collect sociodemographic data, reasons for orthodontist selection, type of Internet use, as well as information on the knowledge, use and evaluation of 14 popular PEPs. A total of 506 questionnaires were evaluated, and a descriptive statistical evaluation was conducted using the χ test.

Camptocormia associated with focal myositis in multiple-system atrophy.

Camptocormia (CC) or pronounced forward flexion of the trunk is a common symptom of Parkinson's disease. We describe 2 patients with probable, respectively possible multiple-system atrophy and CC. Magnetic resonance imaging of the erector trunci showed focal patchy hyperintensities with gadolinium enhancement and muscle biopsy was indicative of variably pronounced focal myositis.
