As an emerging niche colonized by microorganisms, microplastics may selectively enrich pathogens, resulting in crucial ecological risks and potential threats to public health in aquatic environments. However, the enrichment characteristics and ecological risks of pathogens on different microplastic biofilms remain unclear. In this study, 16S rRNA high-throughput sequencing technology was used to investigate the differences in the bacterial community structure, occurrence characteristics of pathogens, and prediction of ecological risks on five typical microplastic biofilms of polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), and polyvinyl chloride (PVC) through a field in-situ incubation experiment.

Data from a maximum of 49,474 animals sired by 526 rams and born from 22,531 ewes over 20 years from 2000 to 2019 were used in this study. Birth type, age of dam, birth year, sex and/or management group, and age at measurement were initially fitted as fixed effects in an animal model with various random effects.

Objective: To study whether Langchuangping granule (LG) could exert its renal protection by down-regulating monocyte chemoattractant protein-1 (MCP-1) via suppressing nuclear factor kappa B (NF-kappaB) signaling pathway in BXSB lupus nephritis (LN) mice. Methods Eighteen male 11-week-old BXSB LN mice were randomly divided into three groups, i.e.

Objective: To evaluate the Th17/Th1 response in HIV infected patients and the mutual relationship between the response of Th17 and Th1.
Methods: 38 chronic HIV infected patients as well as 24 healthy volunteers were performed in this study. The patients were divided into two groups, one group before treatment, the other after therapy.

Crosslinked starch phosphates (CSP) with different contents of phosphate groups were used to adsorb Zn(II) from aqueous solution. Effects of adsorption time, initial concentration of Zn(II) ion, and temperature on the adsorption of Zn(II) by CSP were studied, and the equilibrium, thermodynamics and kinetics of the adsorption process were further investigated. It showed that crosslinked starch phosphates can effectively remove Zn(II) from the solution.
