Riparian zone, an important land-water interface, plays an essential role in maintaining the ecological health of rivers, whereas the effects of Polycyclic aromatic hydrocarbons (PAHs) on the health of biological communities in riparian groundwater remain undetermined. To understand the responses of multiple communities to environmental variables, the distribution and ecosystem risk of 16 PAHs have been investigated in the Beiluo River, China. The distribution of multiple communities in riparian groundwater was investigated by environmental DNA metabarcoding, including 16S rRNA, 18S rRNA, and COI gene sequencing for bacteria, microbial eukaryotes (including algae, fungi, and protozoa), and metazoan, respectively, followed by correlation analysis between multiple communities and PAH contamination levels. The concentration of PAHs in the Beiluo River ranged largely from 35.32 to 728.59 ng/L. Here, the Shannon's diversity index of bacteria (Firmicutes) decreased possibly due to the occurrence of Pyrene, which mainly derives from coal and biomass combustion. Furthermore, the reduced richness of fungi (Ascomycota, Basidiomycota) and algae (Chlorophyta, Chrysophyceae) can be attributed to the presence of medium molecular weight (MMW) PAHs (Pyrene, Benz(a)anthracene, Chrysene), and low molecular weight (LMW) PAHs (Naphthalene, Fluorene, Phenanthrene). The richness and Shannon's diversity index of metazoan (Arthropoda) were promoted owing to MMW PAHs (Chrysene, Fluoranthene) generated from coal and biomass combustion and traffic emission. The ecological risk of PAHs in the groundwater environment of the Beiluo River was characterized as low to medium, where LMW and MMW PAHs posed higher risk than the high molecular weight (HMW) compounds. Overall, this study provides insights into the structures of riparian multi-biological communities altered by PAHs.

Emodin, as a natural active ingredient, has shown great application potential in the fields of medicine, food and cosmetics due to its unique pharmacological effects, such as anti-inflammatory, antioxidant, anti-cancer, etc. In recent years, with the development of science and technology and the increase of people's demand for natural medicine, emodin research has been paid more and more attention by the global scientific research community. The bibliometric analysis of emodin and the construction of knowledge map are still blank.

Unlabelled: Studies have suggested that phytochemicals in green tea have systemic anti-inflammatory and neuroprotective effects. However, the mechanisms behind these effects are poorly understood, possibly due to the differential metabolism of phytochemicals resulting from variations in gut microbiome composition. To unravel this complex relationship, our team utilized a novel combined microbiome analysis and metabolomics approach applied to low complexity microbiome (LCM) and human colonized (HU) gnotobiotic mice treated with an acute dose of powdered matcha green tea.

The 2011 report outlined several recommendations for transforming undergraduate biology education, sparking multiple pedagogical reform efforts. Among these was the Promoting Active Learning and Mentoring (PALM) network, an NSF-funded program that provided mentorship and training to instructors on implementing active learning in the classroom. Here, we provide a perspective on how members of the biology education community in PALM view the recommendations of , drawing upon our experiences both as members of PALM and as leaders of an associated project funded by another NSF grant that hosted PALM alumni at various conferences.

Objective: This study aimed to investigate the help-seeking behaviours among children and young people (CYP) from culturally and linguistically diverse (CALD) backgrounds for mental health (MH) needs in a multicultural Australian population.
Methods: We analysed the electronic medical records (eMR) of 8135 MH-related emergency department (ED) encounters of CYP aged up to 18 years across six public hospitals in the South Western Sydney Local Health District, Australia, from January 2016 to April 2022. Urgency of MH care was grouped into high priority (triage categories 1 and 2, needing to have treatment within 10 minutes) and low-to-moderate (triage categories 3-5, needing to have treatment within 30-120 minutes) presentations.

Purpose: The purpose of this study was to investigate adolescent perspectives of parent-adolescent communication, type 1 diabetes mellitus (T1DM)-specific family conflict, self-efficacy, and their relationship to adolescent self-management of T1DM.
Methods: A cross-sectional survey design was employed. Adolescents completed measures of parent-adolescent communication, T1DM-specific family conflict, self-efficacy, and self-management, which included activation and division of responsibility for management tasks.
