Abstract

Perilla frutescens is an herb traditionally used to treat chronic diseases owing to its antioxidant and anti-inflammatory properties. This study aimed to determine the antioxidant and anti-inflammatory effects of perilla leaf extract (PLE) in TNF-α- treated A549 human lung carcinoma cell line. Perilla frutescens leaves were extracted with 70% et ...

Abstract

We applied a one-dimensional tight-binding model to the study electron transport in a ferromagnetic metal-insulatorferromagnetic metal junction. We included a small external magnetic field perpendicular to the one-dimensional chain as a Zeeman Effect on electron spins. We obtained the transmission and reflection probabilities of an electron across ...

Abstract

Antibiotics are one of the most common drugs that can induce adverse drug reaction (ADR). A retrospective analysis was conducted using suspected antibiotic-related ADR data collected from the Ethiopian Pharmacovigilance Center over a 5-year period (2014-2019). There were a relatively large number of antibiotic-related ADRs (57.9%) containing 462 ...
