RESUMEN
Health literacy is crucial in maintaining good health and well-being, yet community-based studies on health literacy in Nepal are scarce. This study aimed to assess the level of health literacy and identify associated factors among adults in Rasuwa, Nepal. A community-based cross-sectional study was conducted among 253 adults aged above 18 years residing in Kalika Rural Municipality, Rasuwa. Data were collected through face-to-face interviews using the Psychometric Assessment of the European Health Literacy Survey Questionnaire (HLS-EU-Q16). Multivariable logistic regression was used to evaluate independent correlates of health literacy levels. The mean ± SD age of participants was 46.3 ± 16 years. Only about a quarter (23.3%) of participants had adequate health literacy. The participants aged ≤ 45 years (aOR:1.9,95% CI: 1.0-3.6), people who perceived their health status as satisfactory (aOR: 3.1,95% CI: 1.5-6.3), had satisfactory self-rated financial status (aOR: 2.9,95% CI: 1.5-5.5), had satisfactory level of self- related esteem (aOR = 2.7,95% CI: 1.2-6.2), had a stable income (aOR = 1.9, 95% CI:1.0-3.5) were more likely to demonstrate adequate health literacy level. Conversely, illiterate participants (aOR: 0.1, 95% CI: 0.04-0.4) and those engaged in agriculture (aOR: 0.49, 95% CI: 0.2-0.9) had lower odds of having adequate health literacy. This study highlights inadequate health literacy status among approximately three-quarters of the participants. Factors such as age, self-rated health status, financial stability, self-esteem, and income were associated with health literacy levels. These findings underscore the importance of addressing socio-economic and individual factors in promoting health literacy initiatives, particularly targeting vulnerable populations, to improve overall health outcomes and healthcare utilization.
RESUMEN
The European honey bee, Apis mellifera, serves as the principle managed pollinator species globally. In recent decades, honey bee populations have been facing serious health threats from combined biotic and abiotic stressors, including diseases, limited nutrition, and agrochemical exposure. Understanding the molecular mechanisms underlying xenobiotic adaptation of A. mellifera is critical, considering its extensive exposure to phytochemicals and agrochemicals present in the environment. In this study, we conducted a comprehensive structural and functional characterization of AmGSTD1, a delta class glutathione S-transferase (GST), to unravel its roles in agrochemical detoxification and antioxidative stress responses. We determined the 3-dimensional (3D) structure of a honey bee GST using protein crystallography for the first time, providing new insights into its molecular structure. Our investigations revealed that AmGSTD1 metabolizes model substrates, including 1-chloro-2,4-dinitrobenzene (CDNB), p-nitrophenyl acetate (PNA), phenylethyl isothiocyanate (PEITC), propyl isothiocyanate (PITC), and the oxidation byproduct 4-hydroxynonenal (HNE). Moreover, we discovered that AmGSTD1 exhibits binding affinity with the fluorophore 8-Anilinonaphthalene-1-sulfonic acid (ANS), which can be inhibited with various herbicides, fungicides, insecticides, and their metabolites. These findings highlight the potential contribution of AmGSTD1 in safeguarding honey bee health against various agrochemicals, while also mitigating oxidative stress resulting from exposure to these substances.

Genome-enabled biotechnologies have the potential to accelerate breeding efforts in long-lived perennial crop species. Despite the transformative potential of molecular tools in pecan and other outcrossing tree species, highly heterozygous genomes, significant presence-absence gene content variation, and histories of interspecific hybridization have constrained breeding efforts. To overcome these challenges, here, we present diploid genome assemblies and annotations of four outbred pecan genotypes, including a PacBio HiFi chromosome-scale assembly of both haplotypes of the 'Pawnee' cultivar. Comparative analysis and pan-genome integration reveal substantial and likely adaptive interspecific genomic introgressions, including an over-retained haplotype introgressed from bitternut hickory into pecan breeding pedigrees. Further, by leveraging our pan-genome presence-absence and functional annotation database among genomes and within the two outbred haplotypes of the 'Lakota' genome, we identify candidate genes for pest and pathogen resistance. Combined, these analyses and resources highlight significant progress towards functional and quantitative genomics in highly diverse and outbred crops.
