Fish gut symbiotic bacterium Bacillus thuringiensis: RSM optimization for its extracellular lipase enzyme production, lipase-protein purification, characterization, and docking analysis.

Lipase enzymes play a vital role in digestion and nutrient metabolism in host organisms, with symbiotic bacteria producing abundant enzymes, carbohydrates, vitamins, and other nutrients. This study aimed to isolate, identify, and screen lipase-producing bacteria from the gut of Systomus sarana, optimize enzyme production using Response Surface Methodology (RSM), and characterize the extracted lipase protein. A total of 11 bacterial strains were isolated and identified through 16S rRNA sequencing.

Going 'meta': a systematic review of metacognition and functional neurological disorder.

In functional neurological disorder (FND), there is a fundamental disconnect between an apparently intact nervous system and the individuals' ability to consistently perform motor actions, perceive sensory signals and/or access effective cognition. Metacognition, the capacity to self-evaluate cognitive performance, appears highly relevant to FND pathophysiology. Poor metacognition is a potential mechanism via which abnormal models of self and the state of the world could arise and persist unchecked.

Radiofrequency ablation for thyroid nodules (RATED study) - analysis of a learning curve and predictors of success.

Context: Radiofrequency ablation (RFA) is used as treatment for symptomatic thyroid nodules. Factors influencing the volume reduction ratio (VRR) at 12 months are not yet fully understood.

Objective: The primary objective was evaluating the VRR at 12 months after RFA.

Localized K63 ubiquitin signaling is regulated by VCP/p97 during oxidative stress.

Under stress conditions, cells reprogram their molecular machineries to mitigate damage and promote survival. Ubiquitin signaling is globally increased during oxidative stress, controlling protein fate and supporting stress defenses at several subcellular compartments. However, the rules driving subcellular ubiquitin localization to promote concerted response mechanisms remain understudied.

Multi-level encoding of reward, effort, and choice across the frontal cortex and basal ganglia during cost-benefit decision-making.

Adaptive value-guided decision-making requires weighing up the costs and benefits of pursuing an available opportunity. Though neurons across frontal cortical-basal ganglia circuits have been repeatedly shown to represent decision-related parameters, it is unclear whether and how this information is coordinated. To address this question, we performed large-scale single-unit recordings simultaneously across 5 medial/orbital frontal and basal ganglia regions as rats decided whether to pursue varying reward payoffs available at different effort costs.
