Rapid socio-economic development has led to many water environmental issues in small watersheds such as non-compliance with water quality standards, complex pollution sources, and difficulties in water environment management. To achieve a quantitative evaluation of water quality, identify pollution sources, and implement refined management in small watersheds, this study collected monthly seven water quality indexes of four monitoring points from 2010 to 2023, and ten water quality indexes of 23 sampling points in the Shiting River and Mianyuan River which are tributaries of the Tuojiang River Basin. Then, water quality evaluation and pollution source analysis were conducted from both temporal and spatial perspectives using the Water Quality Index (WQI) method, the Absolute Principal Component Scores/Multiple Linear Regression (APCS-MLR) method, and the Positive Matrix Factorization (PMF) receptor modeling technique.

High-quality development of water resources supports high-quality socio-economic development. High-quality development connects high-quality life, and clarifying the key management contents of small watersheds plays an important role in building ecologically clean small watersheds and promoting regional production and life. Previous research on pollution loads has focused on examining the impact of various external drivers on pollution loads but still lacks research on the impact of changes in pollution sources themselves on pollution loads.

Chemotherapy remains a major treatment for malignant tumors, yet the application of standard dose intensity chemotherapy is limited due to the side effects of cytotoxic drugs, especially in old populations. The underlying mechanisms of cytotoxicity and strategies to increase the safety and tolerance of chemotherapy remain to be explored. Using 5-fluorouracil (5-FU), a cornerstone chemotherapeutic drug, we demonstrate that the main cause of death in (AL) fed mice after 5-FU chemotherapy was infection caused by translocation of intestinal opportunistic pathogens.

Macrophages are the primary effectors against potential pathogen infections. They can be "parasitized" by intracellular bacteria, serving as "accomplices", protecting intracellular bacteria and even switching them to persisters. Here, using a freeze-thaw strategy-based microfluidic chip, a "Themis" nanocomplex (TNC) is created.

Article Synopsis
  • DNA damage contributes to stem cell aging, leading to the elimination of damaged cells in skin and blood, while dietary restriction (DR) is known to slow aging in various species, including lab mice.
  • This study reveals that DR significantly delays hair graying in mice subjected to ionizing radiation, extending the resting phase of hair follicles and preventing the loss of hair follicle stem cells (HFSCs) and melanoblasts initially.
  • However, although DR prolongs HFSC quiescence, it ultimately cannot prevent long-term hair graying and melanoblast loss, indicating that separating the effects of DR on stem cell quiescence from DNA repair could help delay stem cell aging.

Article Synopsis
  • - This study investigates the brain functional abnormalities associated with primary open-angle glaucoma (POAG) using resting-state functional MRI (rs-fMRI) to understand the disease's neuropathology and how stable brain connectivity patterns contribute.
  • - Researchers analyzed data from 70 POAG patients and 45 healthy controls, finding that POAG patients exhibited reduced functional stability in key visual areas and increased stability in specific brain regions.
  • - The findings indicate that changes in functional stability in the visual cortex correlate with visual field defects, suggesting that brain connectivity analysis could enhance our understanding of POAG progression.

Intracellular bacteria are the major contributor to the intractability of septic arthritis, which are sequestered in macrophages to undermine the innate immune response and avoid the antibacterial effect of antibiotics due to the obstruction of the cell membrane. Herein, we report a thermoresponsive nanoparticle, which consists of a phase-change material shell (fatty acids) and an oxygen-producing core (CaO-vancomycin). Under external thermal stimulation, the shell of the nanoparticle transforms from a solid phase to a liquid phase.

The aim of this research was to investigate the impact of a diet containing galactooligosaccharide (GOS)-fish peptide (FP) conjugates prepared via Maillard reaction on the colonic fermentation properties and the composition of gut microbiota in Sprague-Dawley rats. The rats were fed the GOS diet, FP diet, GOS and FP mixture (GOS/FP) diet, GOS glycated with FP (80 °C for 120 min, G-GOS/FP) diet, or control (CK) diet for three weeks. Compared to the GOS/FP diet, the G-GOS/FP diet greatly changed the pattern of SCFA production in the hindgut of rats, by increasing the total SCFA (44%), butyrate (55%) and propionate (1.

In Klebsiella pneumoniae, aldehyde dehydrogenases (ALDH) convert 3-hydroxypropionaldehyde (3-HPA) into 3-hydroxypropionic acid (3-HP). Although ALDHs can increase the production of 3-HP in K. pneumoniae, the substrate specificity of ALDH homologues from other microorganisms toward 3-HPA is less documented.

In Klebsiella pneumoniae, 3-hydroxypropaldehyde is converted to 3-hydroxypropionic acid (3-HP) by aldehyde dehydrogenase (ALDH) with NAD(+) as a cofactor. Although ALDH overexpression stimulates the formation of 3-HP, it ceases to accumulate when NAD(+) is exhausted. Here we show that NAD(+) regeneration, together with ALDH overexpression, facilitates 3-HP production and benefits cell growth.

Domestic violence has emerged as a worldwide concern since the 1970s. Although a substantial amount of efforts have been devoted to assessing various aspects of domestic violence, a relatively small number of studies have empirically examined factors that shape public attitudes toward police response to such incidents. Even rarer is investigating the topic from an international, comparative perspective.
