The spread of the coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become a global health crisis. binding affinity SARS-CoV-2 (in particular receptor domain, RBD) to its angiotensin converting enzyme 2 (ACE2) and antibodies is great importance in understanding infectivity COVID-19 evaluating candidate therapeutic for COVID-19. In thi...

A novel class of noscapine derivatives known as 9-arylimino noscapinoids was designed by substituting arylimino groups (Schiff bases) at the C-9 position. These molecules were docked with αβ-tubulin complex and a panel three top scoring molecules, 4-6 based on docking score screened out. bind tubulin robust predicted binding energy -37.24 kcal/mol -45.41 for 4, -39.73 -47.74 5, -43.62 -49.72 6 ...

INTRODUCTION The problem of lumbar stenosis has been analysed at length in the literature as the number of patients with low back pain of this aetiology continues to increase. The aim of this study was:1. to carry out a prospective study assessing the dimensions of spinal canal on the basis of CT data and to compare patient data with a control group.2. to determine if the sagittal and transvers...

objectives: this study evaluated the effect of surface polishing on mercury release from dental amalgam after treatment with 16% carbamide peroxide gel. materials and methods: ninety-six samples from two different amalgam brands were prepared in truncated cone-shaped pvc polymer molds with an external surface area of 195 mm². half of the specimens were polished with green and red rubber, a brus...

introduction in order to treat uveal melanoma , first, radioactive seeds are laid on a silicone- made substance which is called silastic after that they are inserted in the plaque, and finally, this plaque containing silicone-made substance is stitched to the sclera surface. the dose gradient within the tumor and healthy tissues can be varied due to changing the silastic thickness between scler...

since heavy metals are considered as one of the major pollutants threatening, the main goal of this study was to bring out the concentrations of pb, zn and mn in the surface sediments off bushehr in the persian gulf. for this purpose, after collection of samples, the concentrations of the three metals in surface sediments were measured through the atomic absorption. the results were compared wi...

this study was conducted to investigate some moisture-dependent engineering properties of russian olive fruit including fruit dimensions, one thousand seed mass, surface area, sphericity, bulk and true density, angle of sliding and static friction coefficient against different surfaces. the physical properties of russian olive fruit were evaluated as a function of moisture content in the range ...

A quantitative understanding of right ventricular (RV) remodeling in repaired tetralogy of Fallot (rTOF) is crucial for patient management. The objective of this study is to quantify the regional curvatures and area strain based on three-dimensional (3-D) reconstructions of the RV using cardiac magnetic resonance imaging (MRI). Fourteen (14) rTOF patients and nine (9) normal subjects underwent ...
