Varroa Volatiles Offer Chemical Cues to Honey Bees for Initial Parasitic Recognition.

Olfaction mediated by the antennae is a vital sensory modality for arthropods and could be applied as a tool in pest control. The ectoparasitic mite poses a significant threat to the health of the honey bee worldwide and has garnered global attention. To better understand the chemical ecology of this host-parasite relationship, we collected and characterized the volatile organic compounds (VOCs) from and used electroantennography (EAG) to record the responses of honey bee ( and ) antennae to the different VOCs.

Effect of optimized food-based recommendations on nutrient intakes, hemoglobin levels, and memory performance of adolescent girls in East Java, Indonesia.

Background: FAO/WHO introduced food-based dietary guidelines (FBDG) to promote healthy dietary habits. To translate the FBDG, optimized food-based recommendations (FBR) can be developed using linear programming (LP) to address problem nutrients. Despite the importance of local-specific FBR for anemia prevention, no study has reported the effect of nutrition education which promoted FBR in adolescent girls.

Prevalence of resistance-associated substitutions (RAS) in hepatitis C virus in the Former Soviet Union countries.

Objective: The emergence of resistance-associated substitutions (RASs) poses a significant challenge to the effective treatment of hepatitis C virus (HCV) infection using direct-acting antivirals. This study's objective was to observe the prevalence of HCV genotypes and RAS within the Former Soviet Union (FSU) countries.

Methods: We analysed 60 NS3, 313 NS5A and 1119 NS5B sequences of HCV deposited in open-access databases from 11 FSU countries for the prevalence of genotypes and the presence of RAS using the Geno2Pheno software.

Large language models vs human for classifying clinical documents.

Background: Accurate classification of medical records is crucial for clinical documentation, particularly when using the 10th revision of the International Classification of Diseases (ICD-10) coding system. The use of machine learning algorithms and Systematized Nomenclature of Medicine (SNOMED) mapping has shown promise in performing these classifications. However, challenges remain, particularly in reducing false negatives, where certain diagnoses are not correctly identified by either approach.

Influence of drought stress on phosphorus dynamics and maize growth in tropical ecosystems.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.
