Evaluating a river's ecological health: A multidimensional approach.

Evaluating the health of river surface water is essential, as rivers support significant biological resources and serve as vital drinking water sources. While the Water Quality Index (WQI) is commonly employed to evaluate surface water quality, it fails to consider biodiversity and does not fully capture the ecological health of rivers. Here we show a comprehensive assessment of the ecological health of surface water in the lower Yangtze River (LYR), integrating chemical and biological metrics.

Occurrence and risk assessment of azole fungicides during the urban water cycle: A year-long study along the Yangtze River, China.

Azole fungicides (AFs) play an important role in the prevention and treatment of fungal diseases in agricultural crops. However, limited studies are addressing the fate and ecological risk of AFs in the urban water cycle at a large watershed scale. To address this gap, we investigated the spatiotemporal distribution and ecological risk of twenty AFs in the lower reaches of the Yangtze River across four seasons.

The Effect of Psychological Distress on Adolescents' Academic Engagement: The Roles of Social-Emotional Competence and Teachers' Caring Behavior.

Purpose: The relationship between psychological distress (PD) and academic engagement (AE) in adolescents is widely recognized. However, there is a lack of research on the mechanisms behind this correlation, especially in COVID-19 pandemic policy liberalization. This study proposed a moderated mediation model to determine the mediating role of social-emotional competence (SEC) between PD and AE and the moderating role of teachers' caring behavior (TCB).

Study on the thermoluminescence and optically stimulated luminescence of LiMgPO:Dy phosphors synthesized by different methods.

LiMgPO:Dy phosphors were synthesized by high-temperature solid-state method and sol-gel method. The effects of different synthesis methods on crystal structure, morphology, thermoluminescence (TL) properties, and optically stimulated luminescence (OSL) properties of LiMgPO:Dy were studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), TL glow curve and continuous wave OSL (CW-OSL) curves. XRD patterns showed that the crystal phase of the samples synthesized by the two methods is LiMgPO.

miR-215-5p regulates osteoporosis development and osteogenic differentiation by targeting XIAP.

Background: Osteoporosis (OP) is a metabolic disease that involves microstructure destruction and fracture damage. The present study probed into the significance of miR-215-5p in OP progression.

Methods: Serum samples were collected from surgical patients and healthy controls.

High- versus low-viscosity cement vertebroplasty and kyphoplasty for osteoporotic vertebral compression fracture: a meta-analysis.

Background: To compare high- versus low-viscosity bone cement on the clinical outcomes and complications in patients with Osteoporotic vertebral compression fractures (OVCFs) who underwent percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP).

Methods: PubMed, Embase, and the Cochrane Library were searched for papers published from inception up to February 2021 for potentially eligible studies comparing high- versus low-viscosity cement for PVP/PKP. The outcomes were the leakage rate, visual analog scale (VAS), and Oswestry Disability Index (ODI).

[Comparative analysis of modified Dewar method versus arthroscopic double Endobutton fixation technique for the treatment of acute acromioclavicular joint dislocation].

Objective: To compare the clinical outcomes of modified Dewar method versus arthroscopic double Endobutton fixation technique for the treatment of acute acromioclavicular joint dislocation (Rockwood types III-V).

Methods: All cases with acute acromioclavicular joint dislocation (Rockwood types III-V) were treated at our department from October 1997 to October 2009. Among them, 28 cases undergoing modified Dewar method were followed up.
