Youth involvement in serious physical violence and political violence: Similarities and differences in risk factors.

Introduction: Youth involvement in violence and delinquency has received widespread attention in the literature. However, little is known about youth involvement in political violence, especially among youth who live in conflict areas. The current study examined the mechanisms that underlie youth involvement in serious physical and political violence.

Oxytocin and the social facilitation of placebo effects.

Significant clinical improvement is often observed in patients who receive placebo treatment in randomized double-blind placebo-controlled trials. While a proportion of this "improvement" reflects experimental design limitations (e.g.

Complex Interplay Between Cognitive Ability and Social Motivation in Predicting Social Skill: A Unique Role for Social Motivation in Children With Autism.

Impairment in social interaction is a core feature of autism spectrum disorder (ASD), but the factors which contribute to this social skill deficiency are poorly understood. Previous research has shown that cognitive ability can impact social skill development in ASD. Yet, children with ASD whose cognitive abilities are in the normal range nevertheless demonstrate deficits in social skill.

Single-cell expression analyses during cellular reprogramming reveal an early stochastic and a late hierarchic phase.

During cellular reprogramming, only a small fraction of cells become induced pluripotent stem cells (iPSCs). Previous analyses of gene expression during reprogramming were based on populations of cells, impeding single-cell level identification of reprogramming events. We utilized two gene expression technologies to profile 48 genes in single cells at various stages during the reprogramming process.

Direct reprogramming of fibroblasts into embryonic Sertoli-like cells by defined factors.

Sertoli cells are considered the "supporting cells" of the testis that play an essential role in sex determination during embryogenesis and in spermatogenesis during adulthood. Their essential roles in male fertility along with their immunosuppressive and neurotrophic properties make them an attractive cell type for therapeutic applications. Here we demonstrate the generation of induced embryonic Sertoli-like cells (ieSCs) by ectopic expression of five transcription factors.
