Microplastic pollution in the offshore sea, rivers and wastewater treatment plants in Jiangsu coastal area in China.

Offshore areas are particularly important in recognizing microplastics pollution because they are sinks of land imports and sources of ocean microplastics. This study investigated the pollution and distribution of microplastics in the offshore Sea, rivers and wastewater treatment plants (WWTPs) in Jiangsu coastal area in China. Results showed that microplastics were widely present in the offshore area, with an average abundance of 3.

Adenine imprinted beads as a novel selective extracellular DNA extraction method reveals underestimated prevalence of extracellular antibiotic resistance genes in various environments.

Despite severe threats of extracellular antibiotic resistance genes (eARGs) towards public health in various environments, advanced studies have been hindered mainly by ineffective extracellular DNA (exDNA) extraction methods, which is challenged by trace levels of exDNA and inference from abundant coexisting compounds. This study developed a highly selective exDNA extraction method based on molecular imprinting technology (MIT) by using adenine as the template for the first time. Results suggested that adenine imprinted beads were rough spheres at an average size of 0.

Prevalence of psychological distress among people living with HIV/AIDS: a systematic review and meta-analysis.

Although people living with HIV/AIDS (PLWHA) are known to be vulnerable to psychological distress (PD), little is known about the prevalence of PD among PLWHA. A systematic literature search of several databases was conducted from inception to August 2021 focusing on studies reporting on PD symptoms among PLWHA. The overall prevalence estimates were pooled using a random-effects meta-analysis.

Enhanced propagation of intracellular and extracellular antibiotic resistance genes in municipal wastewater by microplastics.

Microplastics (MPs) are an emerging global concern as they are abundant in the environment and can act as vectors of various contaminants. However, whether and how MPs can be vectors of antibiotic resistance genes (ARGs), especially extracellular ARGs (eARGs), remains far from explicit. This study addresses the adsorption of both intracellular ARGs (iARGs) and eARGs by four types of MPs in municipal wastewater, and then explores the potential horizontal gene transfer of iARGs and eARGs exposed to MPs.
