Liver injury with COVID-19: laboratory and histopathological outcome-systematic review and meta-analysis.

Background: The novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been predominantly linked to respiratory distress syndrome, but hepatic injury has also been reported. The mechanism of liver injury is poorly understood.This review aimed to systematically review the current data through laboratory tests and liver tissue pathology to ascertain the correlation of liver involvement in SARS-CoV-2 infection patients.

Oxygen sensing with individual ZnO:Sb micro-wires: effects of temperature and light exposure on the sensitivity and stability.

Nanostructured ZnO has been widely investigated as a gas sensing material. Antimony is an important dopant for ZnO that catalyses its surface reactivity and thus strengthens its gas sensing capability. However, there are not enough studies on the gas sensing of antimony-doped ZnO single wires.

Ameliorative Effects of Honey, Propolis, Pollen, and Royal Jelly Mixture against Chronic Toxicity of Sumithion Insecticide in White Albino Rats.

Sumithion (Fenitrothion) (SUM) is an organophosphorus insecticide used to combat a wide variety of plant pests. Exposure to SUM causes significant toxicity to the brain, liver, kidney, and reproductive organs through, for example, binding to DNA, and it induces DNA damage, which ends with oxidative stress. Therefore, the present study aimed to examine the protective role of bee products: a mixture of honey, propolis, palm pollen, and royal jelly (HPPJ) against SUM-induced toxicity.

The Impact of Royal Jelly against Hepatic Ischemia/Reperfusion-Induced Hepatocyte Damage in Rats: The Role of Cytoglobin, Nrf-2/HO-1/COX-4, and P38-MAPK/NF-κB-p65/TNF-α Signaling Pathways.

Objective: The present study was conducted to elucidate the underlying molecular mechanism as well as the potential hepatoprotective effects of royal jelly (RJ) against hepatic ischemia/ reperfusion (IR) injury.

Methods: Rats were assigned into four groups; sham (received vehicle), IR (30 minutes ischemia and 45 minutes reperfusion), sham pretreated with RJ (200 mg/kg P.O.

Variations of the Static Contact Angle of Ferrofluid Droplets on Solid Horizontal Surfaces in External Uniform Magnetic Fields.

The application of external uniform magnetic fields to ferrofluid droplets affects their magnetic order at the nanoscale as well as their shape at the macroscale, thus changing their contact angle with the surface. In this work, the effects of external uniform magnetic fields on the contact angles between different oil-based ferrofluid droplets and a handful of horizontal surfaces of varying wettability were studied. The contact angle is no longer constant around the ferrofluid droplet; rather, it varies in a rich yet predictable way.

Correlation between scattering properties of silver particle arrays and fluorescence enhancement.

We report on the nanofabrication of patterned silver particle arrays using electron-beam lithography and the evaluation of their optical properties using backscattering and fluorescence spectroscopy. The silver particles varied in size from 100 to 250 nm and were in the shape of circles, squares, and triangles. Three inter-particle separations, 40, 65, and 90 nm as measured from the side of one particle to the side of the next particle, were used.

Study of 22 Egyptian patients with Diamond-Blackfan anemia, corticosteroids, and cyclosporin therapy results.

Objective: Diamond-Blackfan anemia is a rare congenital hypoproliferative anemia of infancy and early childhood. Treatment with corticosteroids is commonly used, but with limited success. Trials with cyclosporin-A (CSA) are not frequently reported.
