Crabtree effect in yeast: a phosphate tug-of-war between fermentation and respiration.

The Crabtree effect in yeast, where cells prefer fermentation over respiration in high -glucose environments, is associated with mitochondrial repression, but the molecular mechanisms were previously unclear. Recently, Vengayil et al. revealed that knocking out the ubp3 gene, encoding a deubiquitinase enzyme, mitigates the Crabtree effect by increasing mitochondrial phosphate levels.

Effect of vehicular vibrations on L-4 lumbar vertebrae - A finite element study.

Lower Back Pain (LBP) is a global health issue, with increasing prevalence, partly attributed to vehicular vibrations experienced by motorcyclists. The L4 lumbar vertebra is responsible for greater mobility and flexibility of the body, but also is the most crucial body element affected by vehicular vibrations. Anthropometric properties, types of speed humps, and vehicle types are the critical variables that impact bone health during riding, need to be studied.

Comprehensive cataloging of miR-363 as a therapeutic & non-invasive biomarker of prostate cancer.

Background & objectives Overcoming the challenge of early diagnosis of prostate cancer (PCa) by exploring molecular biomarkers is urgently needed. With this objective, this study was designed to explore the biomarker and therapeutic potential of miRNA (miR)-363-3p in PCa pathogenesis. Methods Total participants (n=188) were enrolled, and blood and tissue samples were collected from individuals categorized into the control group (n=55), benign prostate hyperplasia (BPH) group (n=60), PCa group (n=48), and castration-resistant PCa (CRPC) group (n=25).

Comparative Evaluation of Cytotoxicity of Zinc Oxide Nanoparticles Mixed With Herbal Extract as an Intracanal Medicament: A Zebrafish Model Study.

Objective In this study, zebrafish embryos are used to study the cytotoxic effects of a novel intracanal medication (ICM) based on zinc oxide nanoparticles (ZnO NPs) loaded with polyherbal extracts ( and ). Material and methods In the present study, a green and sustainable method was employed for the synthesis of ZnO NPs mixed with bark and seed extracts of and to be used as a polyherbal ICM. Formulation of ZnO NPs was confirmed with color change in mixture produced upon dissolving zinc acetate dihydrate in distilled water followed by slow addition of sodium hydroxide solution and herbal extracts.

Discovery and Validation of Novel microRNA Panel for Non-Invasive Prediction of Prostate Cancer.

Background: Early diagnosis remains a challenge for prostate cancer (PCa) due to molecular heterogeneity. The purpose of our study was to explore the diagnostic potential of microRNA (miRNA) in both tissue and serum that may aid in the precise and early clinical diagnosis of PCa.

Materials And Methods: The miRNA expression pattern analysis was carried out in 250 subjects (discovery and validation cohort).
