The SARS-CoV-2 B.1.618 variant slightly alters the spike RBD-ACE2 binding affinity and is an antibody escaping variant: a computational structural perspective.

Continuing reports of new SARS-CoV-2 variants have caused worldwide concern and created a challenging situation for clinicians. The recently reported variant B.1.

Structural-Dynamics and Binding Analysis of RBD from SARS-CoV-2 Variants of Concern (VOCs) and GRP78 Receptor Revealed Basis for Higher Infectivity.

Glucose-regulated protein 78 (GRP78) might be a receptor for SARS-CoV-2 to bind and enter the host cell. Recently reported mutations in the spike glycoprotein unique to the receptor-binding domain (RBD) of different variants might increase the binding and pathogenesis. However, it is still not known how these mutations affect the binding of RBD to GRP78.

Robust Three-Dimensional (3D) Expansion of Bovine Intestinal Organoids: An In Vitro Model as a Potential Alternative to an In Vivo System.

Intestinal organoids offer great promise for disease-modelling-based host-pathogen interactions and nutritional research for feed efficiency measurement in livestock and regenerative medicine for therapeutic purposes. However, very limited studies are available on the functional characterisation and three-dimensional (3D) expansion of adult stem cells in livestock species compared to other species. Intestinal crypts derived from intestinal organoids under a 3D culture system from the small intestine in adult bovine were successfully established and characterised for functionality testing, including the cellular potentials and genetic properties based on immunohistochemistry, immunocytochemistry, epithelial barrier permeability assay, QuantSeq 3' mRNA-Seq.

Differential impact of some metal(loid)s on oxidative stress, antioxidant system, sulfur compounds, and protein profile of Indian mustard (Brassica juncea L.).

Levels of arsenic (As), chromium (Cr), and copper (Cu) are increasing in the soils worldwide. Such contaminants cause toxicity in the plant systems which adversely affects growth and productivity. The objective of the present investigation was to elucidate individual and combined effects of As, Cr, and Cu (100 μM each) stress in metal hyper-accumulator plant Indian mustard (Brassica juncea L.

Potential drug-drug interactions in outpatient department of a tertiary care hospital in Pakistan: a cross-sectional study.

Background: Potential drug-drug interactions (pDDIs) are one of the preventable drug related problems having the risk of serious adverse events or therapeutic failure. In developing countries like Pakistan, this issue remains poorly addressed. The objective of this study was to explore prevalence of pDDIs in the Outpatient Department (OPD) of a tertiary care hospital in Pakistan.

Potential drug-drug interactions in pediatric patients admitted to intensive care unit of Khyber Teaching Hospital, Peshawar, Pakistan: A cross-sectional study.

Purpose: To investigate frequencies, levels, clinical relevance and predictors of potential drug-drug interactions (pDDIs) in pediatric intensive care unit (PICU).

Methods: Case notes of 411 patients were reviewed for pDDIs through Micromedex. Frequencies, levels and clinical relevance of pDDIs were reported.

Potential drug-drug interactions in medical intensive care unit of a tertiary care hospital in Pakistan.

Background Patients admitted to intensive care unit (ICU) present with severe and life-threatening illnesses. Most of them suffer from various comorbidities. They usually receive complex pharmacotherapy with large number of medicines which increase the risk of drug-drug interactions (DDIs).

Schools as potential vaccination venue for vaccines outside regular EPI schedule: results from a school census in Pakistan.

Background: Vaccines are the most effective public health intervention. Expanded Program on Immunization (EPI) provides routine vaccination in developing countries. However, vaccines that cannot be given in EPI schedule such as typhoid fever vaccine need alternative venues.

A study of micronutrient status in pregnancy.

The present study was performed, to analyse the inter-relationship among trace elements: Iron, copper and zinc in pregnancy. Eighty-four pregnant women were compared with 30 age matched nonpregnant healthy controls. Fasting blood samples were analysed for heamoglobin, iron, copper and zinc.

Pseudoxanthoma elasticum and nephrolithiasis: a rare association.

Pseudoxanthoma elasticum (PXE) is a multi-systemic, genetic disorder of connective tissue characterized by progressive calcification and fragmentation of elastic fibers in skin, retina and cardiovascular system. A young patient reported to urologist in emergency with azotemia secondary to acute bilateral obstructive uropathy. Upon successful management, he was found to have full-blown skin and eye manifestations and was evaluated thoroughly regarding extent and potential systemic complications of Pseudoxanthoma elasticum.
