Does audio computer-assisted self-interviewing (ACASI) produce more valid reporting of sexual activity and related behaviors than face-to-face interviews or self-administered interviews? This analysis, based on data collected from over 6,000 unmarried adolescents in two districts of Kenya--Nyeri and Kisumu--indicates substantial and significant differences in reported rates of premarital sex across interview modes, although not always in the expected direction. Our assumption that girls underreport sexual activity in face-to-face interviews by comparison with ACASI is not confirmed by the Nyeri data, but our results from Kisumu are considerably more promising. As for boys, who we believe exaggerate their level of sexual activity in face-to-face interviews, a more nuanced set of expectations regarding the reporting of sensitive behaviors was offered; our results from Kisumu, although not always significant, by and large conform to expectations.

HIV self-sampling and -testing (HIVSS/ST) reduces testing barriers and potentially reaches populations who may not test otherwise. In the Netherlands, at-home HIV tests became commercially available around 2016, but data on user experiences are limited. This study aimed to explore characteristics of users and their experiences with HIVSS/ST.

, a recently described endemic species from southern Peru, belongs to the Amaryllidaceae family and is known for its diversity of alkaloids. Amaryllidoideae have been studied for their diverse biological activities, particularly for their properties in treating neurodegenerative diseases. This work examines the alkaloidal profile using GC-MS and UPLC-MS/MS of alkaloid-enriched extracts obtained from the leaves and bulbs of and their inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes.

, a tropical African plant, is traditionally used to treat several diseases, including fever, inflammation, and malaria. Essential oils (EOs) from the plant's leaves, roots, and trunk bark were obtained by hydrodistillation, and their chemical composition was analyzed by gas chromatography-mass spectrometry (GC-MS). The major constituents identified were virdiflorene (18.

Sexual signals in animals encompass a variety of forms including visual, acoustic, and chemical signals that are fundamental for intra- and interspecific communication, including sexual selection processes. Among these, odor signals play a critical role. Chemical compounds involved in sexual signaling vary in nature, with lipids and proteins being particularly important.
