Appetitive trait profiles in late life: links to eating disorder psychopathology and psychosocial well-being

Abstract Objective Appetitive traits shape eating behaviors across the lifespan, yet their patterns and health correlates in later life remain poorly understood. This study used latent profile analysis (LPA) to identify distinct profiles of appetitive traits among older adults an...

Clinical Outcomes of HIF-2α inhibition in Von Hippel-Lindau Disease: A Multicenter Real-World Study.

BACKGROUND AND OBJECTIVE: Management of von Hippel-Lindau (VHL) disease is challenging due to multisystem involvement and limited systemic treatment options. Belzutifan has shown promising efficacy in clinical trials; however, real-world data remain limited. We aimed to evaluate...

When leaders rock the boat: Leader reputation and the credibility of US commitments

Do allies translate negative assessments of a patron state’s leader into doubts about the credibility of the patron state? Recent work suggests that they do, but this article argues otherwise. It develops a theory of reputational filtering, whereby allied elites interpret leader-...

Firearm carrying practices and motivations: A mixed methods study among adults and youth

Abstract The purpose of this participatory action, mixed methods research study was to identify motivations related to firearm carrying from a qualitative perspective, and then to use quantitative research to characterize the patterns of motivations around carrying. Qualitative i...

Diet-dependent, beneficial and adverse effects of rapamycin on life span of Drosophila melanogaster

Abstract Rapamycin supplementation has been reported to extend life spans in numerous species, including Drosophila melanogaster , but a recent study in this laboratory revealed a marked life-shortening effect in y w male flies. The experiments reported here were performed to cha...

Identification of a membrane transporter for dimethylsulfoniopropionate uptake in marine eukaryotic phytoplankton

Marine microalgae obtain essential sulfur through energetically costly, assimilatory reduction of sea-salt sulfate, so the ability for osmotrophic incorporation of reduced sulfur would confer them adaptability in energy-limiting conditions. Dimethylsulfoniopropionate (DMSP) is a...

HPV Vaccination Predictors Among College Students

College students remain at increased risk for acquiring human papillomavirus (HPV), yet HPV vaccination coverage remains suboptimal despite the availability of a safe and effective vaccine. This study examined predictors of HPV vaccination and HPV- and HPV vaccine-related knowled...

Conservation of Long G4-rich (LG4) genomic enhancer regulations

Long G4-rich regions (LG4s) are defined as DNA sequences containing a high density of guanine triplets capable of forming non-B DNA structures called G-quadruplexes (G4s). These regions frequently overlap with enhancers, which are regulatory DNA elements that modulate gene expres...
