The helicases are motor proteins participating in a range of nucleic acid metabolisms. RNA helicase families are characterized by the presence of conserved motifs. This article reports a comprehensive in silico analysis of Bos taurus DExH/D helicase members. Bovine helicases were identified using the helicase domain sequences including 38 DDX (DEAD box) and 16 DHX (DEAH box) members. Signature motifs were used for the validation of these proteins. Putative sub cellular localization and phylogenetic relationship for these RNA helicases were established. Comparative analysis of these proteins with human DDX and DHX members was carried out. These bovine helicase have been assigned putative physiological functions. Present study of cattle DExH/D helicase will provides an invaluable source for the detailed biochemical and physiological research on these members.

Background And Hypothesis: The dysconnectivity hypothesis of schizophrenia suggests that atypical neural communication underlies the disorder's diverse symptoms. Building on this framework, we propose that specific synaptic disturbances within thalamo-cortical circuits contribute to an imbalance in excitation and inhibition, leading to alteration in oscillations. Our study investigates these alterations and explores whether synaptic restoration can remediate neural activity of schizophrenia and align it with healthy patterns.

G-quadruplexes (G4) are four-stranded nucleic acid structures formed within sequences containing repeated guanine tracts separated by intervening loop regions. Abundant in the human genome, they play crucial roles in transcription regulation and genome maintenance. Although theoretically capable to adopt 26 different folding topologies─primarily differing in loop arrangements─only 14 of these have been observed experimentally.

Invasive Candidiasis infections are a clinical challenge, with limited effective therapeutic agents and increasing resistance. The discovery of new antifungal agents is urgently required. Here, we developed a new series of 2-methyl-1,4-naphthoquinone (Menadione) Tethered to 1H-1,2,3-triazolyl-selenoester in good yields, which exhibit antifungal potential activity against Candida species.

Modelling cardiovascular disease is at the forefront of efforts to use computational tools to assist in the analysis and forecasting of an individual's state of health. To build trust in such tools, it is crucial to understand how different approaches perform when applied to a nominally identical scenario, both singularly and across a population. To examine such differences, we have studied the flow in aneurysms located on the internal carotid artery and middle cerebral artery using the commercial solver Ansys CFX and the open-source code HemeLB.

Background: Molnupiravir, an FDA-approved antiviral for the treatment of COVID-19, requires reliable analytical methods to ensure its quality and safety due to its therapeutic importance.
Objectives: This study presents the development of a stability-indicating RP-HPLC method for estimating molnupiravir-related impurities in capsule formulations. An unknown impurity is structurally elucidated using LC-TQ/MS and 1H and 1³C NMR spectroscopy.
