Two-sample Mendelian randomization (MR) allows the use of freely accessible summary association results from genome-wide association studies (GWAS) to estimate causal effects of modifiable exposures on outcomes. Some GWAS adjust for heritable covariables in an attempt to estimate direct effects of genetic variants on the trait of interest. One, both or neither of the exposure GWAS and outcome GWAS may have been adjusted for covariables.

We performed a simulation study comprising different scenarios that could motivate covariable adjustment in a GWAS and analysed real data to assess the influence of using covariable-adjusted summary association results in two-sample MR.

In the absence of residual confounding between exposure and covariable, between exposure and outcome, and between covariable and outcome, using covariable-adjusted summary associations for two-sample MR eliminated bias due to horizontal pleiotropy. However, covariable adjustment led to bias in the presence of residual confounding (especiasured confounders) is required to direct sensitivity analyses and interpret results with appropriate caution.The field of health promotion advocates a socioecological approach to health that addresses a variety of physical, social, environmental, political and cultural factors. Encouraging a holistic approach, health promotion examines many aspects of health and wellbeing, including physical, mental, sexual, community, social and ecological health. Despite this holism, there is a noticeable absence of discussion surrounding spirituality and spiritual health. This research study explored how leading scholars in Canadian health promotion understand the place of spirituality in health promotion. Using the fourth edition of Health Promotion in Canada (Rootman et al., 2017) as the sampling frame of recognized leaders in the field, 13 semi-structured qualitative interviews were conducted with authors from the book. This study is situated within a critical health promotion approach that utilizes methodologies aiming for social justice, equity and ecological sustainability. I argue that by avoiding spirituality within health promotion frameworks and education, the secularism of health promotion and its underlying values of Eurocentric knowledge production and science remain invisible and rarely critiqued. This study intends to open up possibilities for centering spiritual and non-Western epistemologies and ways of knowing that have been marginalized, such as Indigenous understandings of health and wellbeing. https://www.selleckchem.com/products/xl413-bms-863233.html Restoring right relations with Indigenous peoples in Canada has taken on new urgency with the calls to action of the Truth & Reconciliation Commission report (NCTR, 2015). This is one important way that health promotion can fulfill its promise of being inclusive, relevant and effective for human and planetary wellbeing.Calonectria henricotiae (Che) and C. pseudonaviculata (Cps) are destructive fungal pathogens causing boxwood blight, a persistent threat to horticultural production, landscape industries, established gardens, and native ecosystems. link2 Although extracellular proteins including effectors produced by fungal pathogens are known to play a fundamental role in pathogenesis, the composition of Che and Cps extracellular proteins has not been examined. Using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and bioinformatics prediction tools, 630 extracellular proteins and 251 cell membrane proteins of Che and Cps were identified in the classical secretion pathway in the present study. In the non-classical secretion pathway, 79 extracellular proteins were identified. The cohort of proteins belonged to 364 OrthoMCL clusters, with the majority (62%) present in both species, and a subset unique to Che (19%) and Cps (20%). These extracellular proteins were predicted to play important roles in cell structure, regulation, metabolism, and pathogenesis. link3 A total of 124 proteins were identified as putative effectors. Many of them are orthologs of proteins with documented roles in suppressing host defense and facilitating infection processes in other pathosystems, such as SnodProt1-like proteins in the OrthoMCL cluster OG5_152723 and PhiA-like cell wall proteins in the cluster OG5_155754. This exploratory study provides a repository of secreted proteins and putative effectors that can provide insights into the virulence mechanisms of the boxwood blight pathogens.Lay health worker-led health promotion interventions are well received within racial and ethnic minority communities. Increasing numbers of trained lay health workers will be needed to meet global health goals. The purpose of this process evaluation was to gain insights about how lay health worker as interventionists used theory-based approaches within a nutrition and physical activity health behavior change intervention in a clinical trial enrolling immigrant and refugee families. Data were comprised of ongoing reflective writing statements from four health workers about their implementation of the intervention. Using content analysis three themes emerged (i) encouraging setting of small, family focused and relevant goals, (ii) being flexible in content delivery and (iii) being personally transformed (i.e. gained a sense of meaning from their experience). Lay health worker interventionist reflections on practice revealed they delivered the intervention within the primacy of the family partnering relationship by attending to unique family needs, and adjusting educational content and goal setting accordingly. Our results provide guidance for training and process evaluation of lay health worker intervention delivery in ethnically and racially diverse populations. Incorporating real-time reflection upon what was learned about skills of facilitating family motivation and family confidence enhanced affective learning and may be useful in future research studies and health promotion practice. The processes identified including setting small goals, flexibility and personal transformation could be considered in future lay health worker-delivered health promotion interventions.CRISPR-Cas immune systems process and integrate short fragments of DNA from new invaders as spacers into the host CRISPR locus to establish molecular memory of prior infection, which is also known as adaptation in the field. Some CRISPR-Cas systems rely on Cas1 and Cas2 to complete the adaptation process, which has been characterized in a few systems. In contrast, many other CRISPR-Cas systems require an additional factor of Cas4 for efficient adaptation, the mechanism of which remains less understood. Here we present biochemical reconstitution of the Synechocystis sp. PCC6803 type I-D adaptation system, X-ray crystal structures of Cas1-Cas2-prespacer complexes, and negative stained electron microscopy structure of the Cas4-Cas1 complex. Cas4 and Cas2 compete with each other to interact with Cas1. In the absence of prespacer, Cas4 but not Cas2 assembles with Cas1 into a very stable complex for processing the prespacer. Strikingly, the Cas1-prespacer complex develops a higher binding affinity toward Cas2 to form the Cas1-Cas2-prespacer ternary complex for integration. Together, we show a two-step sequential assembly mechanism for the type I-D adaptation module of Synechocystis, in which Cas4-Cas1 and Cas1-Cas2 function as two exclusive complexes for prespacer processing, capture, and integration.Profiling molecular features associated with the morphological landscape of tissue is crucial for investigating the structural and spatial patterns that underlie the biological function of tissues. In this study, we present a new method, spatial gene expression patterns by deep learning of tissue images (SPADE), to identify important genes associated with morphological contexts by combining spatial transcriptomic data with coregistered images. SPADE incorporates deep learning-derived image patterns with spatially resolved gene expression data to extract morphological context markers. Morphological features that correspond to spatial maps of the transcriptome were extracted by image patches surrounding each spot and were subsequently represented by image latent features. The molecular profiles correlated with the image latent features were identified. The extracted genes could be further analyzed to discover functional terms and exploited to extract clusters maintaining morphological contexts. We apply our approach to spatial transcriptomic data from different tissues, platforms and types of images to demonstrate an unbiased method that is capable of obtaining image-integrated gene expression trends.With the tremendous increase of publicly available single-cell RNA-sequencing (scRNA-seq) datasets, bioinformatics methods based on gene co-expression network are becoming efficient tools for analyzing scRNA-seq data, improving cell type prediction accuracy and in turn facilitating biological discovery. However, the current methods are mainly based on overall co-expression correlation and overlook co-expression that exists in only a subset of cells, thus fail to discover certain rare cell types and sensitive to batch effect. Here, we developed independent component analysis-based gene co-expression network inference (ICAnet) that decomposed scRNA-seq data into a series of independent gene expression components and inferred co-expression modules, which improved cell clustering and rare cell-type discovery. ICAnet showed efficient performance for cell clustering and batch integration using scRNA-seq datasets spanning multiple cells/tissues/donors/library types. It works stably on datasets produced by different library construction strategies and with different sequencing depths and cell numbers. We demonstrated the capability of ICAnet to discover rare cell types in multiple independent scRNA-seq datasets from different sources. Importantly, the identified modules activated in acute myeloid leukemia scRNA-seq datasets have the potential to serve as new diagnostic markers. Thus, ICAnet is a competitive tool for cell clustering and biological interpretations of single-cell RNA-seq data analysis.GTPBP3 and MTO1 cooperatively catalyze 5-taurinomethyluridine (τm5U) biosynthesis at the 34th wobble position of mitochondrial tRNAs. Mutations in tRNAs, GTPBP3 or MTO1, causing τm5U hypomodification, lead to various diseases. However, efficient in vitro reconstitution and mechanistic study of τm5U modification have been challenging, in part due to the lack of pure and active enzymes. A previous study reported that purified human GTPBP3 (hGTPBP3) is inactive in GTP hydrolysis. Here, we identified the mature form of hGTPBP3 and showed that hGTPBP3 is an active GTPase in vitro that is critical for tRNA modification in vivo. Unexpectedly, the isolated G domain and a mutant with the N-terminal domain truncated catalyzed GTP hydrolysis to only a limited extent, exhibiting high Km values compared with that of the mature enzyme. We further described several important pathogenic mutations of hGTPBP3, associated with alterations in hGTPBP3 localization, structure and/or function in vitro and in vivo. Moreover, we discovered a novel cytoplasm-localized isoform of hGTPBP3, indicating an unknown potential noncanonical function of hGTPBP3. Together, our findings established, for the first time, the GTP hydrolysis mechanism of hGTPBP3 and laid a solid foundation for clarifying the τm5U modification mechanism and etiology of τm5U deficiency-related diseases.
