Exosomes derived from highly scalable and regenerative human progenitor cells promote functional improvement in a rat model of ischemic stroke.

Globally, there are 15 million stroke patients each year who have significant neurological deficits. Today, there are no treatments that directly address these deficits. With demographics shifting to an older population, the problem is worsening.

Differential recruitment drives pathogen-mediated competition between species in an amphibian chytridiomycosis system.

Pathogens that infect multiple host species have an increased capacity to cause extinctions through parasite-mediated apparent competition. Given unprecedented and continuing losses of biodiversity due to Batrachochytrium dendrobatidis (Bd), the causative fungus of the amphibian skin disease chytridiomycosis, a robust understanding of the mechanisms driving cross-species infection dynamics is essential. Here, we used stage-structured, susceptible-infected compartmental models to explore drivers of Bd-mediated apparent competition between two sympatric amphibians, the critically endangered Litoria spenceri and the non-threatened Litoria lesueurii.

Social Representations of pregnancy among trans men.

Objective: to understand the meanings and experiences of pregnancy among trans men in light of the Theory of Social Representations.

Methods: this is a qualitative, descriptive and exploratory study, carried out with trans men selected for convenience and availability. Data production took place from September to October 2021, via the Google Meet® platform, based on interviews with a semi-structured script.

When less is more: Short-Term efficacy of a gamified personalized normative feedback intervention for college students.

Despite various intervention efforts, college drinking remains a concern, and while personalized normative feedback (PNF) has proven effective, attempts to deliver it in a way that minimizes reactance and maximizes student engagement have been slow to emerge. This study examined the short-term effects of CampusGandr, a mobile gamified PNF intervention for college students. The game took place over 16 weeks (1 round per week) during the fall semester and included weekly PNF on various topics related to college life, including alcohol.
