Although we agree that historical myths function to increase cooperation in the groups that share them, we propose that the mechanisms at work may include affective states. We suggest that sharing historical myths can create a felt sense of intimacy, similarity, and security among group members, which increases trust and motivates cooperation, even without particular beliefs about population structure.

The health sector has faced long-standing challenges in drivers of worker behaviours and performance, such as job satisfaction, which have been worsened by COVID-19. Structural issues including high workloads and poor working conditions have long contributed to dissatisfaction among health workers. The pandemic escalated unsafe working conditions, causing workers' deaths, increasing burnout rates, and contributing to exodus from health-care jobs.

The current study assessed PPTE exposures during the CTP and examined associations with mental disorders among RCMP cadets. Participants were cadets (n = 449, 24.

Methods: Eastern box turtles were head-started by Jekyll Island State Park Authority's Georgia Sea Turtle Center. Free-ranging resident box turtles on Jekyll Island State Park were captured.
Medulloblastoma (MB) is the most common malignant brain tumour in children. The Sonic Hedgehog (SHH)-medulloblastoma subtype arises from the cerebellar granule neuron lineage. Terminally differentiated neurons are incapable of undergoing further cell division, so an effective treatment for this tumour could be to force neuronal differentiation.

These acquired cysteines can be both driver mutations and sites targeted by precision therapies. However, despite their ubiquity, nearly all acquired cysteines remain unidentified via chemoproteomics; identification is a critical step to enable functional analysis, including assessment of potential druggability and susceptibility to oxidation.

Objective: This systematic review aimed to summarize published research on the psychology of rock climbing, find commonalities and disagreements within the current research and illuminate future research areas.
Electrospinning is an outstanding manufacturing technique for producing nano-micro-scaled fibrous scaffolds comparable to biological tissues. However, the solvents used are normally hazardous for the health and the environment, which compromises the sustainability of the process and the industrial scaling. This novel study compares different machine learning models to predict how green solvents affect the morphology, topography and mechanical properties of gelatin-based scaffolds.

To identify potential chemoprevention starting points we screened a sub-set of the CSIRO Australia Compound Collection for compounds with slow-action in vitro activity against Plasmodium falciparum. This work identified N,N-dialkyl-5-alkylsulfonyl-1,3,4-oxadiazol-2-amines as a new antiplasmodial chemotype (e.

To gain insight into phylogenetic structure and mechanisms of pathogenicity for this bacterial species, we compared genomes for 99 samples from 6 countries (Australia, Bosnia and Herzegovina, Brazil, China, France and USA) and 4 host species (domestic sheep, domestic goats, bighorn sheep and caribou). Core genome sequences of assemblies from domestic sheep and goats fell into two well-supported phylogenetic clades that are divergent enough to be considered different bacterial species, consistent with each of these two clades having an evolutionary origin in separate host species.

Sources of contamination include manure on hides, environmental contamination, ingredients from external sources, and lymph nodes. Swine lymph nodes are often incorporated into ground meat, as their anatomical location makes removal labor prohibitive.

Method: A representative sample of RCMP ( = 1,324; 76.5% men) completed the self-report survey.
Hybridization can provide evolutionary benefits (e.g., population resilience to climate change) through the introduction of adaptive alleles and increase of genetic diversity.

To do so, existing research about online group therapy must be built upon to provide a comprehensive understanding of the efficacious delivery of this therapy modality. Thus, a systematic review was conducted to collate what is currently known in the published and grey literature on online group therapy, using the PRISMA framework.

Yet, cage-promoted organocatalysis has remained elusive, in large part due to synthetic accessibility of robust and functional scaffolds. Herein, we report the acyl transfer catalysis properties of robust, hexaamide cages in organic solvent.

However, this practice presents disadvantages that can be mitigated through tissue-engineered implants. The aim of this study is to explore how machine learning can mechanically evaluate 2D and 3D polyvinyl alcohol (PVA) electrospun scaffolds (one twisted filament, 3 twisted filament and 3 twisted/braided filament scaffolds) for their use in different tissue engineering applications.

Conformationally flexible, chemically robust structures are needed for adaptable guest binding and catalysis, but rapidly exchanging systems are difficult to resolve in solution. Here, we use low-cost calculations and high-throughput crystallisation to identify accessible conformers of a recently reported organic cage by 'locking' them in the solid state.
