Increased methane production associated with community shifts towards Methanocella in paddy soils with the presence of nanoplastics.

Background: Planetary plastic pollution poses a major threat to ecosystems and human health in the Anthropocene, yet its impact on biogeochemical cycling remains poorly understood. Waterlogged rice paddies are globally important sources of CH. Given the widespread use of plastic mulching in soils, it is urgent to unravel whether low-density polyethylene (LDPE) will affect the methanogenic community in flooded paddy soils.

Short-Chain Fatty Acids Alleviate Vancomycin-Caused Humoral Immunity Attenuation in Rabies-Vaccinated Mice by Promoting the Generation of Plasma Cells via Akt-mTOR Pathway.

Mounting evidence suggests that gut microbial composition and its metabolites, including short-chain fatty acids (SCFAs), have beneficial effects in regulating host immunogenicity to vaccines. However, it remains unknown whether and how SCFAs improve the immunogenicity of the rabies vaccine. In this study, we investigated the effect of SCFAs on the immune response to rabies vaccine in vancomycin (Vanco)-treated mice and found that oral gavage with butyrate-producing bacteria () and butyrate supplementation elevated RABV-specific IgM, IgG, and virus-neutralizing antibodies (VNAs) in Vanco-treated mice.

Nurse practice environment, perceived organizational support, general well-being, occupational burnout and turnover intention: A moderated multi-mediation model.

Aims: To test the relationship between practice environment and turnover intention, considering the moderation of perceived organizational support (POS) and the mediation of general well-being (GWB) and occupational burnout (OB) among the nurse population.

Design: A cross-sectional survey design.

Methods: Based on a sample of 474 nurses from two hospitals between May 2020 and September 2021, a moderated multi-mediation model was tested in which GWB and OB served as two mediators between practice environments and nurses' turnover intention, and POS was regarded as a moderator between practice environments and GWB.

Delay-disorder fiber Bragg grating recognition and calibration method for a Fourier domain mode-locked wavelength-swept laser-based interrogation system.

Fourier domain mode-locking has been used in fiber Bragg grating interrogation for high-speed and long-distance measurement. But the delays induced by long fiber between multisensors and interrogation systems result in nonneglected wavelength error in this high-speed wavelength-swept system. More seriously, the cross-sweep cycle and different distance delays may cause the delay-disorder problem which makes the system unable to determine the order of the delayed peaks and unable to address the location of sensors with corresponding wavelength-encoding characteristics.

Effects of dentifrice containing hydroxyapatite on dentinal tubule occlusion and aqueous hexavalent chromium cations sorption: a preliminary study.

In order to endow environmental protection features to dentifrice, hydroxyapatite (HA) was added to ordinary dentifrice. The effects on dentinal tubule occlusion and surface mineralization were compared after brushing dentine discs with dentifrice with or without HA. The two types of dentifrice were then added to 100 µg/ml of hexavalent chromium cation (Cr(6+)) solution in order to evaluate their capacities of adsorbing Cr(6+) from water.
