Coefficient Bounds for a Certain Class of Analytic and Bi-Univalent Functions
, 2015 In this paper, we introduce and investigate a subclass of analytic and bi-univalent functions in the open unit disk U. By using the Faber polynomial expansions, we obtain upper bounds for the coefficients of functions belonging to this analytic and bi ...

British Journal of Clinical Pharmacology, EarlyView.Aim Novel oral polio vaccine type 2 (nOPV2) was used under the WHO emergency use listing for circulating vaccine‐derived polio virus (cVDPV) outbreaks from 2021 to 2023. We assessed nOPV2 adverse events following immunization (AEFIs) and compared its safety profile to other vaccines using VigiBase.

Atomically precise metal cluster enzymes for pathological tissue regeneration
BMEMat, EarlyView.Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.
