Article Abstract

What is a stem cell? Is stemness an intrinsic or extrinsic property? What role does the microenvironment play in the stemness identity? We distinguish four identities for normal and cancerous stem cells and explore their consequences for therapeutic strategy choice in the oncology setting. Acquisition of genetic and epigenetic alterations during cell transformation and disease progression questions the stability of the stemness property's identity in cancers.

Gender dysphoria is a condition characterized by distress due to a mismatch between a person's gender identity and their assigned gender at birth. This study aimed to compare sexual satisfaction and complication rates in patients undergoing feminizing gender affirming surgery (fem-GAS) using two techniques: standard penile inversion vaginoplasty (PIV) and robotic peritoneal vaginoplasty (RPGAV). We conducted a retrospective analysis data from a prospective registry (2017-2022).

Objectives: To explore experiential education (EE) and preceptor development experts' perceptions of priorities for preceptor development aimed at supporting learner professional identity formation (PIF) and create a framework for preceptor development to inform future preceptor training programs.

Methods: This multi-component study involved: 1) conducting virtual focus groups of EE and preceptor development experts to explore perceived preceptor development needs, including content and learning outcomes, 2) utilizing a modified nominal group technique (NGT) to identify priorities for preceptor development and 3) creating a preceptor development framework for supporting learner PIF. Transcripts were analyzed to identify specific content areas of focus and practical program insights.

Resident macrophages play integral roles in maintaining tissue homeostasis and function. In the skin, prenatally seeded, specialized macrophages patrol sensory nerves and contribute to their regeneration after injury. However, mechanisms underlying the long-lasting postnatal commitment of these nerve-associated macrophages remain largely elusive.

Online communities such as Reddit offer neurodivergent individuals a unique space to express emotions, seek psychosocial support, and negotiate identity outside conventional social constraints. Understanding how these communities articulate and structure emotional discourse is essential for inclusive technology design. This study employed a hybrid natural language processing (NLP) framework that integrates lexicon-based sentiment analysis (VADER) with transformer-based topic modeling (BERTopic).

Regular cannabis use and promotive attitudes among diverse adolescents in the United States: The role of age and intersecting social positions.

Drug Alcohol Depend

Division of General Pediatrics and Adolescent Health, Department of Pediatrics, University of Minnesota, 717 Delaware St. SE, Minneapolis, MN 55414, United States. Electronic address:

Purpose: Cannabis use is common in adolescence and has been associated with negative health effects, and higher prevalence has been seen among marginalized youth. Research has not examined regular use or attitudes promoting use, particularly taking an approach grounded in intersectionality and minority stressors. The present study examines how regular cannabis use, perceptions of risk, approval from parents and friends, and peer norms of use differ across multiple social positions.
