The potent antimicrobial properties of several chloroquinones prompted the synthesis of nineteen new 2.5-disubstituted anilino-3.6-dichloro-1.4-benzoquinone derivatives by reacting 2.5-dichloro-p-benzoquinone with many of the official antimicrobial sulphonamides and other related amines. Testing of six representative samples for their antimicrobial activity revealed good inhibitory results on the growth of five microorganisms.

An alternative approach to biokinetic modelling for phenol pollutant degradation and microbial growth using Genetic Programming.

Biokinetic models can optimise pollutant degradation and enhance microbial growth processes, aiding to protect ecosystem protection. Traditional biokinetic approaches (such as Monod, Haldane, etc.) can be challenging, as they require detailed knowledge of the organism's metabolism and the ability to solve numerous kinetic differential equations based on the principles of micro, molecular biology and biochemistry (first engineering principles) which can lead to discrepancies between predicted and actual degradation rates.

Background: The rapid evolution of large language models (LLMs), such as Bidirectional Encoder Representations from Transformers (BERT; Google) and GPT (OpenAI), has introduced significant advancements in natural language processing. These models are increasingly integrated into various applications, including mental health support. However, the credibility of LLMs in providing reliable and explainable mental health information and support remains underexplored.

This study provides preliminary evidence for real-time functional magnetic resonance imaging neurofeedback (rt-fMRI NF) as a potential intervention approach for internet gaming disorder (IGD). In a preregistered, randomized, single-blind trial, young individuals with elevated IGD risk were trained to downregulate gaming addiction-related brain activity. We show that, after 2 sessions of neurofeedback training, participants successfully downregulated their brain responses to gaming cues, suggesting the therapeutic potential of rt-fMRI NF for IGD (Trial Registration: ClinicalTrials.

School of Public Health and Preventive Medicine, Monash University, Melbourne, Australia.
Background And Objectives: Lipid metabolism in older adults is affected by various factors including biological aging, functional decline, reduced physiologic reserve, and nutrient intake. The dysregulation of lipid metabolism could adversely affect brain health. This study investigated the association between year-to-year intraindividual lipid variability and subsequent risk of cognitive decline and dementia in community-dwelling older adults.

Background: Insulin resistance often occurs in patients with chronic kidney disease (CKD) owing to mineral and bone metabolism disorders. Fibroblast growth factor (FGF)-23 and soluble klotho (s-KL) play crucial roles in linking CKD with mineral and bone metabolism.
Objective: This study aimed to examine the relationship between insulin resistance and FGF-23 and s-KL in patients with non-diabetic pre-dialysis patients with CKD.
