Evaluation of COVID-19 cases treated in the intensive care unit in a coastal city hospital during the pandemic.

SARS-CoV-2 is a novel coronavirus that infects the respiratory tract and was the causing agent of COVID-19, declared a pandemic by the World Health Organization on March 11, 2020. Several studies have been carried out to understand the pathophysiology of the disease, immune reactions, and risk factors that could aggravate the condition and predict the prognosis of patients. Therefore, this study aimed to evaluate the most prevalent laboratory data of hospitalized patients associated with discharge or death.

Time-scale dependence of solar wind-based regression models of ionospheric electrodynamics.

The solar wind influence on geospace can be described as the sum of a directly driven component, or dayside reconnection, and an unloading component, associated with the release of magnetic energy via nightside reconnection. The two processes are poorly correlated on short time scales, but exactly equal when averaged over long time windows. Because of this peculiar property, regression models of ionospheric electrodynamics that are based on solar wind data are time scale specific: Models derived from 1 min resolution data will be different from models derived from hourly, daily, or monthly data.

Effect of metal primers on the bond strength of resin cement to Co-Cr alloy.

Background: To evaluate the effects of adhesive systems and primer systems on microshear bond strength of chemically activated resin cemented to Co-Cr cast dental alloy.

Methods: Seventy-two rectangular blocks of Co-Cr metal alloy were manufactured and air-abraded with 50-μm Al2O3 particles. Metal primers (alloy primer [AP] or Clearfil ceramic primer [CP]) and adhesives (Adper Scotchbond Multi-Purpose Adhesive activated by Adper Scotchbond Multi-Purpose Adhesive Catalyst [SASC], or Primer & Bond 2.

Influence of chloramine-T disinfection on elastomeric impression stability.

Objective: The aim of this study was to evaluate the stability of elastomer through detail reproduction and its dimensional stability (DS) after disinfection with 0.2% chloramine-T.

Materials And Methods: The elastomeric impression dental materials used in this study were polydimethylsiloxane (Oranwash L), polyvinyl siloxane (Express), polysulfide (Permlastic), and polyether (Impregum Soft).

Central and peripheral effects of physical exercise without weight reduction in obese and lean mice.

To investigate the central (hypothalamic) and peripheral effects of exercise without body weight change in diet-induced obesity (DIO). Twelve-week-old male C57Bl/6 mice received a control (C) or a high-fat diet (H). Half of them had free access to running wheels for 5 days/week for 10 weeks (CE) and HE, respectively).
