RNA metabolism is focused on RNA molecules and encompasses all the crucial processes an RNA molecule may or will undergo throughout its life cycle. It is an essential cellular process that allows all cells to function effectively. The transcriptomic landscape of a cell is shaped by the processes such as RNA biosynthesis, maturation (RNA processing, folding, and modification), intra- and inter-cellular transport, transcriptional and post-transcriptional regulation, modification, catabolic decay, and retrograde signaling, all of which are interconnected and are essential for cellular RNA homeostasis.

Plant peptides, synthesized from larger precursor proteins, often undergo proteolytic cleavage and post-translational modifications to form active peptide hormones. This process involves several proteolytic enzymes (proteases). Among these, SBTs (serine proteases) are a major class of proteolytic enzymes in plants and play key roles in various regulatory mechanisms, including plant immune response, fruit development and ripening, modulating root growth, seed development and germination, and organ abscission.

Heterostructuring of two-dimensional materials offers a robust platform to precisely tune optoelectronic properties through interlayer interactions. Here we achieved a strong interlayer coupling in a double-layered heterostructure of sulfur isotope-modified adjacent MoS monolayers two-step chemical vapor deposition growth. The strong interlayer coupling in the MoS(S)/MoS(S) was affirmed by low-frequency shear and breathing modes in the Raman spectra.

Background: The present study investigated the antioxidant, antimicrobial, and partial enzymatic properties of 52 thermophilic cyanobacteria isolates .
Materials And Methods: The DPPH scavenging method was applied to test the antioxidant potential of isolates' methanol extracts. Agar block diffusion and agar well diffusion methods were used to evaluate the antimicrobial activity and measured in milimeters.

Solid-phase microextraction (SPME) is a fast and simple sample preparation technique that enables the enrichment of analytes, and it is used in combination with other detection techniques to provide accurate and sensitive analytical methods. SPME is widely used in environmental monitoring, food safety, life analysis, biomedicine, and other applications. The extractive coating is the core of the SPME technique, and the properties of the extractive coating greatly influence extraction selectivity and efficiency, as well as the enrichment effect.
