Recycling honey bee drone brood for sustainable beekeeping.

Pollination by insects is vital for global agriculture, with honey bees (Apis mellifera L.) being the most important pollinators. Honey bees are exposed to numerous stressors, including disease, pesticides, and inadequate nutrition, resulting in significant colony losses.

Comparative analysis of PFASs concentrations in fur, muscle, and liver of wild roe deer as biomonitoring matrices.

Background: Recently, environmental pollution has become a significant concern for human, animal, and environmental health, fitting within the "One Health" framework. Among the various environmental contaminants, per- and polyfluoroalkyl substances (PFASs) have gathered substantial attention due to their persistence, bioaccumulation, and adverse health effects. This study aimed to compare the levels of 12 PFASs in the fur, liver, and muscle of wild roe deer to evaluate the feasibility of using fur as a non-invasive biomonitoring matrix.

Multianalytical investigation reveals psychotropic substances in a ptolemaic Egyptian vase.

This study presents a comprehensive multimodal analytical study of an Egyptian ritual Bes-vase, of the 2nd century BCE employing cutting-edge proteomics, metabolomics, genetics techniques, and synchrotron radiation-based Fourier Transformed Infrared microSpectroscopy (SR µ-FTIR) to characterize organic residues of its content. We successfully identified the presence of various functional, bioactive, psychotropic, and medicinal substances, shedding light on the diverse components of a liquid concoction used for ritual practices in Ptolemaic Egypt. Using LC-MS/MS with a new methodological approach, we identified key proteins and metabolites, enabling the identification of botanical sources, confirmed by genetic sequences.

Antibacterial Activity of Ag+ on ESKAPEE Pathogens In Vitro and in Blood.

Introduction: Bloodstream infections are a significant threat to soldiers wounded in combat and contribute to preventable deaths. Novel and combination therapies that can be delivered on the battlefield or in lower roles of care are urgently needed to address the threat of bloodstream infection among military personnel. In this manuscript, we tested the antibacterial capability of silver ions (Ag+), with long-appreciated antibacterial properties, against ESKAPEE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter species, and Escherichia coli) pathogens.
