This study assessed the safety of trace metal concentrations in locally produced nutritive food-drinks consumed in Yenagoa metropolis, Bayelsa State, Nigeria. Three different drink types (viz, tiger nut juice, a mixture of tiger nut and soya bean juice and soya bean juice) were purchased from various locations in Yenagoa metropolis, Bayelsa State, Nigeria, between January and February 2024. Thirty samples were analyzed for trace metals using atomic absorption spectrophotometry.

Recent research has revealed the calcium signaling significance in the production of cellulases in . While vacuoles serve as the primary calcium storage within cells, the function of vacuolar calcium transporter proteins in this process remains unclear. In this study, we conducted a functional characterization of four vacuolar calcium transport proteins in .

The importance of manganese superoxide dismutase (Mn-SOD), an evolutionarily ancient metalloenzyme that maintains the integrity and function of mitochondria, was studied in oxidative stress-treated cultures. Deletion of the Mn-SOD gene () increased both the menadione sodium bisulfite (MSB)-elicited oxidative stress and the deferiprone (DFP)-induced iron limitation stress sensitivity of the strain. Moreover, DFP treatment enhanced the MSB sensitivity of both the gene deletion mutant and the reference strain.

The concentration of small molecules reflects the normality of physiological processes in the human body, making the development of simple and efficient detection equipment essential. In this work, inspired by a facile strategy in point-of-care detection, two devices were fabricated to detect small molecules via photocurrent measurement. A linear response of the photocurrent against the concentration of the small molecules was found.

Objective: to determine the distribution of genotypes of genetic polymorphism of manganese superoxide dismutaseand to assess the ventilation lung capacity in children- residents of radioactively contaminated areas and childrenexposed to stressful life events during the war period.
Materials And Methods: The study involved school-age children - residents of radioactively contaminated areas(RCA) and children exposed to stressful life events during wartime. All those examined had no clinical signs of respiratory pathology.
