In the current psychological debate, low replicability of psychological findings is a central topic. While the discussion about the replication crisis has a huge impact on psychological research, we know less about how it impacts public trust in psychology. In this article, we examine whether low replicability damages public trust and how this damage can be repaired. Studies 1–3 provide correlational and experimental evidence that low replicability reduces public trust in psychology. Additionally, Studies 3–5 evaluate the effectiveness of commonly used trust-repair strategies such as informati

The Niger Delta region is the oil producing area of Nigeria, which consists of highly diverse ecosystems that are supportive of numerous species of terrestrial and aquatic fauna and flora. Crude oil spills endanger fish hatcheries in coastal water and also contaminate valuable fish. This study examines the effects of oil spills on fish production in the Niger Delta of Nigeria from 1981-2015 using an estimable Cobb Douglas production function. The findings suggest that oil production and spills negatively affect fish production, while farm labour has a positive effect on fish production. On the

The application of adoptive T cell therapies, including those using chimeric antigen receptor (CAR)-modified T cells, to solid tumors requires combinatorial strategies to overcome immune suppression associated with the tumor microenvironment. Here we test whether the inflammatory nature of oncolytic viruses and their ability to remodel the tumor microenvironment may help to recruit and potentiate the functionality of CAR T cells. Contrary to our hypothesis, VSVmIFNβ infection is associated with attrition of murine EGFRvIII CAR T cells in a B16EGFRvIII model, despite inducing a robust proinflam

The present study is undertaken to assess the alleviating effects of antimicrobial peptide cecropin A on inflammatory bowel disease (IBD) in C57BL/6 mice and changes in the gut microbiota, compared to an antibiotic gentamicin. Different doses of cecropin A were intraperitoneally injected into C57BL/6 mice for 5 days to determine the safe doses. The injection doses at ≤ 15 mg/kg showed no negative impact on the liver, heart, spleen and kidney. The severe and moderate IBD mice model was successfully established via supplementation of 4% or 2.5% dextran sulfate sodium (DSS) in drinking water for

INTRODUCTION: Although health expenditure in sub-Saharan African countries is the lowest compared with other regions in the world, most African countries have improved their budget allocations to health care over the past 15 years. The majority of health care sources in sub-Saharan Africa are private and largely involve out-of-pocket expenditure, which may prevent healthcare access. Access to healthcare is a known predictor of infant mortality. Therefore the objective of this study is to determine the impact of health care expenditure on infant mortality in sub-Saharan Africa.

BACKGROUND: Gestational diabetes mellitus (GDM) contributes to adverse pregnancy and birth outcomes. In recent decades, extensive research has been devoted to the early prediction of GDM by various methods. Machine learning methods are flexible prediction algorithms with potential advantages over conventional regression. OBJECTIVE: The purpose of this study was to use machine learning methods to predict GDM and compare their performance with that of logistic regressions.

Interventions that aim to increase water availability for agriculture hold great potential for improving nutrition through increasing food production, generating income, enhancing water access and sanitation and hygiene conditions, and through strengthening women’s empowerment. Yet there is scarce evidence on the linkages between small-scale irrigation and the pathways through which nutrition outcomes can be achieved. Using data from a cross-sectional household survey collected in Ethiopia and Tanzania, we explored the potential for small-scale irrigation to contribute to improved diets, and i
