Adult stem cells balance self-renewal and differentiation to build, maintain and repair tissues. The role of signalling pathways and transcriptional networks in controlling stem cell function has been extensively studied, but there is increasing appreciation that mechanical forces also have a crucial regulatory role. Mechanical forces, signalling pathways and transcriptional networks must be coordinated across diverse length and timescales to maintain tissue homeostasis and function.

The environmental pollutant cadmium (Cd) poses a threat to human health through consumption of contaminated foodstuffs culminating in chronic nephrotoxicity. Mitochondrial dysfunction and excessive reactive oxygen species (ROS) are key to Cd cellular toxicity. Cd-lipid interactions have been less considered.

Limosilactobacillus reuteri DSM 17938 (L. reuteri DSM 17938) was one of the most widely used probiotics in humans for gastrointestinal disorders, but few studies have investigated its role in drug-induced liver injury (DILI). Here, we evaluated the efficacy of L.

Background: Care procedures for preterm infants can induce stress that may disrupt homeostasis, possibly altering cerebral perfusion or oxygenation. We evaluated the physiological and cerebral oxygenation changes during the routine care of very preterm infants.
Methods: We analyzed the changes in heart and respiratory rates and in systemic and regional cerebral oxygen saturation of 27 very preterm infants, defining three care periods of 5 min each: 30 min before care, 30 min during care, and 30 min after care.
Objectives: To describe changes in the volume and types of emergency medical services (EMS) calls for children during the COVID-19 pandemic and after availability of the COVID-19 vaccine ("reopening period").
Methods: A retrospective cross-sectional study of EMS 9-1-1 responses to children under 18 years for all causes over a 4-year period (2019-2022) reported in the National Emergency Medical Services Information System (NEMSIS) dataset. Data was stratified into three periods, Pre-pandemic, Pandemic and Reopening.
