Guenons (tribe Cercopithecini) are the most widely distributed nonhuman primate in the tropical forest belt of Africa and show considerable phenotypic, taxonomic, and ecological diversity. However, genomic information for most species within this group is still lacking. Here, we present a high-quality de novo genome (total 2.90 Gb, contig N50 equal to 22.7 Mb) of the mona monkey (Cercopithecus mona), together with genome resequencing data of 13 individuals sampled across Nigeria. Our results showed differentiation between populations from East and West of the Niger River ∼84 ka and potential ancient introgression in the East population from other mona group species. The PTPRK, FRAS1, BNC2, and EDN3 genes related to pigmentation displayed signals of introgression in the East population. Genomic scans suggest that immunity genes such as AKT3 and IL13 (possibly involved in simian immunodeficiency virus defense), and G6PD, a gene involved in malaria resistance, are under positive natural selection. Our study gives insights into differentiation, natural selection, and introgression in guenons.

Purpose: Adolescence is a period of developmental transition marked by a high prevalence of mental health challenges. The emergence of these challenges underscores the importance of encouraging help-seeking behaviors among adolescents to mitigate negative psychological outcomes. Gaining a deeper understanding of the lived experiences of adolescents can inform intervention development and increase access to care.

Purpose: A growing body of research supports the influence of gender norms on adolescent mental health globally. There is a lack of qualitative studies, however, that elicit adolescents' own perspectives on these issues across diverse cross-cultural environments. The current study seeks to address these gaps through a qualitative exploration of gendered influences on mental health among adolescents living in 13 countries.

The Gulf of Guinea rainforests, renowned for exceptional primate endemism, are increasingly fragmented and face severe hunting-induced defaunation. However, the long-term persistence of primate assemblages in these hunted forests remains understudied. The unprotected Ebo-Ndokbou-Makombe landscape, designated the Yabassi Key Biodiversity Area (YKBA), represents one of the region's largest remaining forest tracts, yet its primate community is largely unexplored.

Background: Various medicaments have been utilized as an aid for wound healing following vital pulp treatment. Many of them are synthetic in origin and have disadvantages as limited amount of cytotoxicity and great expense. Hence, to tackle these drawbacks, naturally derived blended scaffolds have been employed in renovative dental field.

Background: The burden of Respiratory Syncytial Virus (RSV) infection in adults is of interest in the context of recently-licensed vaccines. However, burden estimates are affected by test error associated with the testing platform, and number and type of samples tested.
Methods: We conducted a prospective cohort study of adults with acute lower respiratory tract disease (aLRTD) hospitalised in Bristol, UK, from April 2022-March 2023.
