Seroprevalence of SARS-CoV-2 in wet market workers in Dhaka, Bangladesh in 2022.

Objectives: We assessed the transmission of SARS-CoV-2 and vaccine receipt in a representative sample of wet market workers in a highly dense, low-income setting. Wet markets are key in many Asian settings, including Dhaka, Bangladesh, for fresh food, including animal protein.

Methods: During early 2022, we assessed the prevalence of anti-SARS-CoV-2 antibodies in a random sample of poultry and vegetable workers in 15 wet markets, and investigated associations with socio-demographic characteristics and COVID-19 vaccination.

Exploring the Versatility of Azine Derivatives: A Comprehensive Review on Synthesis and Biological Applications.

Organic compounds containing azines, di-imines, or bis-Schiff-bases have two azomethine (-CH=N-) functional groups associated with a bridging component. These constituents have attracted attention from a diversity of disciplines, comprising coordination, medicinal, agriculture chemistry, and organic synthesis, because of their comprehensive chemical reactivity and nature. This study determines common synthetic approaches and various biological and pharmacological activities of several substituted bis-Schiff byproducts.

Structural insights into binding-site access and ligand recognition by human ABCB1.

ABCB1 is a broad-spectrum efflux pump central to cellular drug handling and multidrug resistance in humans. However, how it is able to recognize and transport a wide range of diverse substrates remains poorly understood. Here we present cryo-EM structures of lipid-embedded human ABCB1 in conformationally distinct apo-, substrate-bound, inhibitor-bound, and nucleotide-trapped states at 3.

A Case of Primary Aldosteronism Masquerading as Bartter and Gitelman Syndromes.

Primary aldosteronism (PA) is a common cause of secondary hypertension, with familial hyperaldosteronism (FH) contributing to a lesser number of cases. FH type IV, a rare subtype, has hardly been reported as a subtype of PA cases. We present a case of a 27-year-old female who presented to the emergency department with circumoral tingling and numbness.

Genetic Assessment of Living Kidney Transplant Donors: A Survey of Canadian Practices.

Background: Kidney failure is a prevalent condition with tendency for familial clustering in up to 27% of the affected individuals. Living kidney donor (LKD) transplantation is the optimal treatment option; however, in Canada, more than 45% of LKDs are biologically related to their recipients which subjects recipients to worse graft survival and donors to higher future risk of kidney failure. Although not fully understood, this observation could be partially explained by genetic predisposition to kidney diseases.
