Direct and indirect reciprocity are two fundamental mechanisms that promote prosocial behavior within groups and across societies. Here, we review recent work that illustrates how a (direct and indirect) reciprocity framework can illuminate our understanding of several factors related to prosocial behavior - namely group membership, gossip, and third-party punishment. We propose that each of these factors can promote prosocial behavior via proximate psychological mechanisms related to direct and indirect reciprocity: reputational concern, expectations, and anticipation of future interaction. Finally, we discuss the implications of adopting such a framework and highlight a number of avenues for future research.

This study aimed to explore the awareness, willingness, and engagement with pre-exposure prophylaxis (PrEP) among high-risk Chinese men who have sex with men (MSM) and to investigate the factors influencing its use. A cross-sectional survey of 1800 HIV-negative MSM was conducted in Chengdu, Suzhou, and Wuhan between June 2022 and February 2023 through in-person and online recruitment methods. Univariate and multivariate logistic regression analyses were used to identify predictors of PrEP use.

Water dynamics are investigated in binary osmolyte-water mixtures, exhibiting a microscopic heterogeneity driven by molecular aggregation, on the basis of molecular dynamics (MD) simulation studies. The protecting osmolyte TMAO molecules in solution are evenly dispersed without the formation of noticeable osmolyte aggregates, while the denaturant TMU molecules aggregate readily, generating microscopic heterogeneity in the spatial distribution of component molecules in TMU-water mixtures. A combined study of MD simulation with graph theoretical analysis and spatial inhomogeneity measurement with -values in the two osmolyte solutions revealed that the translational and rotational motions of water in the microheterogeneous environment of TMU-water mixtures are less hindered than those in the homogeneous media of TMAO-water mixtures.

Preclinical and clinical xenotransplantation trials have shown that successful outcomes depend on a number of factors including the prevention of xenozoonoses. Preclinical trials involving pig kidneys and hearts transplanted into various non-human primates have revealed the potential impact of pig pathogens being present in the transplanted organ/tissue, mainly viruses. The concept of "designated pathogen-free donor animals" was developed to ensure elimination of pathogens during the breeding of donor animals to mitigate this occurrence.

Cell-interface engineering is a way to functionalize cells through direct or indirect self-assembly of functional materials around the cells, showing an enhancement to cell functions. Among the materials used in cell-interface engineering, natural biomolecules play pivotal roles in the study of biological interfaces, given that they have good advantages such as biocompatibility and rich functional groups. In this review, we summarize and overview the development of studies of natural biomolecules that have been used in cell-biointerface engineering and then review the five main types of biomolecules used in constructing biointerfaces, namely DNA polymers, amino acids, polyphenols, proteins and polysaccharides, to show their applications in green energy, biocatalysis, cell therapy and environmental protection and remediation.

Background: Previous studies have reported that anxiety negatively affects professional identity (PI), and clinical belongingness is positively correlated with PI among nursing interns. However, little is known about the relationship between anxiety, PI, and clinical belongingness among nursing interns.
Objective: To explore the relationship between PI, clinical belongingness, and anxiety among nursing interns, and to demonstrate the mediating role of clinical belongingness in this relationship.
