Dietary intakes, food behaviours and health indicators among Métis youth in Manitoba, Canada.

Objective: Poor diets and food insecurity during adolescence can have long-lasting effects, and Métis youth may be at higher risk. This study, as part of the Food and Nutrition Security for Manitoba Youth study, examines dietary intakes, food behaviours and health indicators of Métis compared with non-Métis youth.

Design: This observational cross-sectional study involved a cohort of adolescents who completed a self-administered web-based survey on demographics, dietary intake (24-h recall), food behaviours, food security and select health indicators.

Priming from within: TLR2 dependent but receptor independent activation of the mammary macrophage inflammasome by Streptococcus uberis.

Introduction: is a member of the pyogenic cluster of commonly associated with intramammary infection and mastitis in dairy cattle. It is a poorly controlled globally endemic pathogen responsible for a significant cause of the disease worldwide. The ruminant mammary gland provides an atypical body niche in which immune cell surveillance occurs on both sides of the epithelial tissue.

Health Care Utilization and Perceived Quality of Care in a Colombian Indigenous Health Organization.

Indigenous governance of health care has increasingly been advocated among Indigenous peoples in many countries. However, there is limited research that has empirically examined its benefits. In 2020/21, we conducted a survey of 2113 Indigenous Wayuu individuals in Colombia who received services from the Indigenous Wayuu led health care insurance organization Anas Wayuu and its network of service providers, and Wayuu individuals who received services from non-Indigenous health insurance organizations.

Influenza induces lung lymphangiogenesis independent of YAP/TAZ activity in lymphatic endothelial cells.

The lymphatic system consists of a vessel network lined by specialized lymphatic endothelial cells (LECs) that are responsible for tissue fluid homeostasis and immune cell trafficking. The mechanisms for organ-specific LEC responses to environmental cues are not well understood. We found robust lymphangiogenesis during influenza A virus infection in the adult mouse lung.

Multicompartment duct platform to study epithelial-endothelial crosstalk associated with lung adenocarcinoma.

Previous lung-on-chip devices have facilitated significant advances in our understanding of lung biology and pathology. Here, we describe a novel lung-on-a-chip model in which human induced pluripotent stem cell-derived alveolar epithelial type II cells (iAT2s) form polarized duct-like lumens alongside engineered perfused vessels lined with human umbilical vein endothelium, all within a 3D, physiologically relevant microenvironment. Using this model, we investigated the morphologic and signaling consequences of the KRAS mutation, a commonly identified oncogene in human lung adenocarcinoma (LUAD).
