Covid-19: Novel Coronavirus Outbreak

An electrochemical biosensor was constructed by convectively assembling polystyrene (PS) beads on a gold electrode to detect SAR-Cov-2 virus via partial nanochannel blockage by virus particles. Nanochannel blockage hinders the diffusion of a redox probe and causes attenuation of oxidation current, allowing quantification of the viral load by measuring the changes in oxidation currents before and after virus incubation.

High flow nasal cannula (HFNC) reduces the need for intubation in patients with hypoxaemic acute respiratory failure (ARF). Our data suggest that a trial of HFNC could be considered to increase chances of survival in patients with ARF due to coronavirus disease 2019 (COVID-19) pneumonitis and a do-not-intubate (DNI) order, especially in those with a good WHO performance status.

Synthetic SARS-CoV-2 and Omicron variant detection with a cost-effective silicon nanowire sensor has been demonstrated with high sensitivity, selectivity, and a fast response. The sensor reaches a 4 cps limit of detection (LoD), even for the Omicron variant, without any genome amplification, and with strong selectivity. The platform is made with industrially compatible techniques, which in perspective may allow a widespread diffusion.

Assessment of the quality of the digital marketing tools implemented by Pecorino Siciliano PDO-producing companies: Usability of the corporate website and amount of activity on Facebook brand pages.

This review describes the smart and intelligent biosensors for effective diagnosis and management of COVID-19 used for the detection of SARS-CoV-2. The importance, advantages and limitations are explained and also the promise as commercial detection devices are discussed.

In reporting rates of myocarditis post COVID19 vaccination, breaking down rates by age, sex, dose, and manufacturer results in higher reported estimates than studies that report overall rates in the population.

COVID-associated rashes in adults usually associate with more severe COVID-19 illness. For older, comorbid patients with mild to moderate COVID-19 illness who develop a rash, administer early immunomodulating therapy to mitigate disease progression.

The most common cause of UR is the existence of an old uterine scar, but in this case, the rapture occurred during the second trimester from a non C/S scar. This is very rare and unusual and it worth urgent operation to save the patient.

New [60]fullerene hybrids endowed with steroid and monosaccharide moieties are obtained through a cyclopropanation reaction. The structure of monoadducts were determined by spectroscopic and analytical study. Theoretical calculations predicted the most stable conformations and determine the factors that control the hybrid molecules′ geometry. The molecular docking studies suggested the possible application of these compounds as anti-SARS-CoV-2.
