Spatio-temporal analysis of formaldehyde and its association with atmospheric and environmental variables over the Southeast Asian region using satellite data.

This study investigates the spatio-temporal distribution of formaldehyde (HCHO) over the mainland Southeast Asian region (including Northeast India) from 2019 to 2022 using TROPOMI satellite data. HCHO is a key atmospheric trace gas which is influenced by both natural processes and anthropogenic activities. We analyze HCHO levels in relation to atmospheric species including carbon monoxide (CO), nitrogen dioxide (NO), and environmental factors such as land surface temperature (LST), precipitation (PPT), fire radiative power (FRP), and enhanced vegetation index (EVI).

Rho and riboswitch-dependent regulations of mntP gene expression evade manganese and membrane toxicities.

The trace metal ion manganese (Mn) in excess is toxic. Therefore, a small subset of factors tightly maintains its cellular level, among which an efflux protein MntP is the champion. Multiple transcriptional regulators and a manganese-dependent translational riboswitch regulate the MntP expression in Escherichia coli.

Investigating the impact of nanoplastics in altering the efficacy of clarithromycin antibiotics through In vitro studies.

Plastics have significant global implications due to their environmental contamination from extensive use and improper disposal. Among plastic particles, nanoplastics (<1 μm) pose notable risks to organisms and ecosystems due to their high surface area, reactivity, and potential to carry environmental pollutants. This study explores the interaction between polystyrene nanoplastics (PSNPs) and clarithromycin (CLA), a broad-spectrum antibiotic, focusing on their combined impact on insulin (INS) and antibiotic-resistant (AMR) bacteria.

Aromaticity of Heterocyclic Compounds and Their Corrosion Inhibition Property: Experimental and Theoretical Analysis.

Heterocycle derived moieties, namely, -(4-methoxyphenyl)-1-(1-pyrrol-2-yl)methanimine (MPM), 1-(furan-2-yl)--(4-methoxyphenyl)methanimine (FMM), and -(4-methoxyphenyl)-1-(thiophen-2-yl)methanimine (MTM), were synthesized followed by analysis of their structural aspects using FTIR and H NMR spectroscopic techniques. The corrosion retarding abilities of the same were distinguished by gravimetric and certain electrochemical measures for mild steel in 0.5 M HSO, and MTM was obtained with maximum inhibition efficiency of 97.
