Background: Given the demographic shift towards an older population, it is crucial to understand the determinants and implications of psychological distress among this demographic group. This study explores the relationship between health self-management and psychological distress in older Chinese adults, focusing on the mediating role of general self-efficacy (GSE).
Methods: We conducted a cross-sectional study in five districts of Shanghai from 1 November to 31 December 2021, employing a random cluster sampling method.
Article Synopsis
- Emerging transformation products of organic micropollutants, like N-acetylated sulfonamides (N-AcSAs), raise concerns due to their unknown environmental impacts and toxicity.
- The study investigated the reaction kinetics and mechanisms of N-AcSAs in various treatments, including chlorination, photodegradation, and solar treatments, revealing that the reactions are pH-dependent and dominated by specific oxidants.
- Results indicate that while solar-based methods can eliminate N-AcSAs, the transformation processes generate persistent and toxic secondary products, highlighting the need for better management and risk assessment of these byproducts.
Slope length is an important factor in soil erosion modeling, and the reasonable automatic extraction of slope length is of great significance in soil erosion research. However, previous studies have mainly focused on the regional scale, and how to effectively extract slope length at the slope scale deserves further research. In this study, a slope length extraction algorithm based on slope streamlines method (SSM) is proposed for the slope length extraction problem in geomorphology, and it is compared with three existing slope length calculation methods.

View Article and Find Full Text PDFThe probiotic role of lactic acid bacteria (LAB) in regulating intestinal microbiota to promote human health has been widely reported. However, the types and quantities of probiotics used in practice are still limited. Therefore, isolating and screening LAB with potential probiotic functions from various habitats has become a hot topic.

Methods: Three groups of samples, untargeted metabolomics analysis of healthy controls (HC), latent tuberculosis infection patients (LTBI), and active tuberculosis patients (TB), were analyzed using gas chromatography time-of-flight mass spectrometry (GC-TOF MS) and ultra-high performance liquid chromatography-quantitative mass spectrometry (UHPLC-QE-MS). Both univariate and multivariate and statistical analyses were used to select differential metabolites (DMs) among group comparison, and LASSO regression analysis was employed to discover potential diagnostic biomarkers.

November 2011
Article Synopsis
- The study introduces a new system for classifying Alzheimer's disease using data from the ADNI dataset, which improves upon traditional methods.
- It combines registration-based and overlap-based similarity measures, enhanced through a self-smoothing operator and a diffusion process to better analyze brain MRIs.
- The system achieves significant accuracy improvements in classifying brain MRIs into normal, mild cognitive impairment, and Alzheimer's categories compared to existing approaches.
