To investigate the male genetic legacy of the Arab rule in southern Europe during medieval times, we focused on specific Northwest African haplogroups and identified evolutionary close STR-defined haplotypes in Iberia, Sicily and the Italian peninsula. Our results point to a higher recent Northwest African contribution in Iberia and Sicily in agreement with historical data. southern Italian regions known to have experienced long-term Arab presence also show an enrichment of Northwest African types. The forensic and genomic implications of these findings are discussed.

Third-party adolescents (those aware of peer conflict as neither aggressors nor victims) can help shape their peers' emotional responses to perceived victimization. Emotion regulation promotes resilience for those who have been victimized, and heightened anger can exacerbate negative outcomes. This study sought to understand how ethnically diverse victimized adolescents described third-party actions that amplified their anger and calmed their emotions-and whether there were gender, racial/ethnic, or school-level patterns.

Article Synopsis
  • TACE is the standard treatment for patients with unresectable, non-metastatic hepatocellular carcinoma, and this study evaluates the effectiveness of adding lenvatinib and pembrolizumab to TACE compared to a placebo.
  • The multicenter, randomised, double-blind phase 3 study (LEAP-012) involved participants from 137 sites across 33 countries who were randomly assigned to receive either TACE with the new drugs or TACE with a placebo.
  • The primary endpoints were progression-free survival and overall survival, and the results reported are from the first interim analysis, which serves as the final analysis for progression-free survival.

Background: Health behavior change theories provide a conceptual basis to promote physical activity, one of which is the Self-Determination Theory (SDT). This cross-sectional study compared SDT constructs, specifically exercise goal setting, exercise planning, and outcome expectations, with objectively assessed Moderate-To-Vigorous Physical Activity (MVPA) among a demographically diverse cohort of adults.

Methods: Participants were 18 to 74 years with prediabetes or type 2 diabetes not prescribed insulin and were physically inactive by self-report.

Background: Despite an established association between heart failure (HF) and lung cancer (LC), there is limited evidence available regarding mortality patterns among the older (≥65 years) population in the United States.

Methods: The mortality data, spanning 1999 to 2019, was surveyed using the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database with HF and LC identified as underlying or contributing causes of death. Crude and age-adjusted mortality rates (AAMR) were calculated per 100,000 individuals.

Analysis of genome-scale evolution has been difficult in large, endangered animals because opportunities to collect high-quality genetic samples are limited. There is a need for novel field-friendly, cost-effective genetic techniques. This study conducted an exome-wide analysis of a total of 42 chimpanzees (Pan troglodytes) across six African regions, providing insights into population discrimination techniques.
