Programming hydrogel adhesion with engineered polymer network topology.

Hydrogel adhesion that can be easily modulated in magnitude, space, and time is desirable in many emerging applications ranging from tissue engineering and soft robotics to wearable devices. In synthetic materials, these complex adhesion behaviors are often achieved individually with mechanisms and apparatus that are difficult to integrate. Here, we report a universal strategy to embody multifaceted adhesion programmability in synthetic hydrogels.

Reserpine improves Enterobacteriaceae resistance in chicken intestine via neuro-immunometabolic signaling and MEK1/2 activation.

Salmonella enterica persist in the chicken gut by suppressing inflammatory responses via expansion of intestinal regulatory T cells (Tregs). In humans, T cell activation is controlled by neurochemical signaling in Tregs; however, whether similar neuroimmunological signaling occurs in chickens is currently unknown. In this study, we explore the role of the neuroimmunological axis in intestinal Salmonella resistance using the drug reserpine, which disrupts intracellular storage of catecholamines like norepinephrine.

Neighborhoods and health during the transition to adulthood: A scoping review.

Research suggests that neighborhoods play an important role in shaping health outcomes across the life course, but the neighborhood-health link during the transition to adulthood period (18-29 years) is not well studied. A scoping review of 24 studies used thematic analysis to examine the theoretical and methodological approaches of the neighborhood-health literature during this period. Themes illustrate the varied approaches used in this research, including diversity in how neighborhood is defined, theoretical variation regarding the importance of the transition period and the neighborhood-health link, and the importance of gender and race/ethnicity to this area of study.
