Organ injury accelerates stem cell differentiation by modulating a fate-transducing lateral inhibition circuit.

Injured epithelial organs must rapidly replace damaged cells to restore barrier integrity and physiological function. In response, injury-born stem cell progeny differentiate faster compared to healthy-born counterparts, yet the mechanisms that pace differentiation are unclear. Using the adult Drosophila intestine, we find that injury speeds cell differentiation by altering the lateral inhibition circuit that transduces a fate-determining Notch signal.

Cumulative Social Disadvantage and Medicinal Cannabis Use Among Younger Adults in Rural Communities: A Mixed Methods Approach.

This mixed-methods study investigated the role of medicinal cannabis use among younger adults who live in rural communities and experience high levels of cumulative social disadvantage (CSD). Results are based on cross-sectional surveys and online interviews with 153 younger adults (18-35-years old) in rural California. We assessed participants' levels of CSD (high, medium, and low) and examined associations with perceived general physical and mental health and with medicinal use of cannabis (MUC).

Decay Rates of Maternal Tetanus, Diphtheria, and Pertussis Antibody Levels in Early and Moderate-to-Late Preterm and Term Infants at Birth and at Two Months.

A post hoc analysis of maternally derived antibodies at birth and age 2 months following second trimester maternal Tdap vaccination between 20 and 24 weeks' gestational age (GA) showed a faster decay rate of Tdap-related immunoglobulin G in early preterms born before 32 weeks' GA compared with moderate-to-late preterms and full-terms. This is different from previous studies and merits further research.
