Changes in Selected Biochemical Markers of Honey Bees Exposed to Fermented Common Tansy Solution ( L.).

Honey bees use pollen and nectar from flowers to produce food. Because they often forage on crops, they are at risk of being exposed to plant protection products (PPPs), both directly and in stored food. Due to the adverse effects of synthetic PPPs on pollinators, biopesticides may be a viable alternative.

Metabolism gene expression in worker honey bees after exposure to 50Hz electric field - semi-field analysis.

The investigation of the effects of artificial 50 Hz electric field (E-field) frequency on Apis mellifera is a relatively new field of research. Since the current literature focuses mainly on short-term effects, it is unknown whether E-fields have permanent effects on bees or whether their effects can be neutralized. In this study we assessed gene expression immediately after exposure to the E-field, as well as 7 days after exposure.

Macrophages as carriers of boron carbide nanoparticles dedicated to boron neutron capture therapy.

Background: The use of cells as carriers for the delivery of nanoparticles is a promising approach in anticancer therapy, mainly due to their natural properties, such as biocompatibility and non-immunogenicity. Cellular carriers prevent the rapid degradation of nanoparticles, improve their distribution, reduce cytotoxicity and ensure selective delivery to the tumor microenvironment. Therefore, we propose the use of phagocytic cells as boron carbide nanoparticle carriers for boron delivery to the tumor microenvironment in boron neutron capture therapy.

Early Refill of an Opioid Medication: Recognizing Personal Biases Through Clinical Vignettes and OSCEs.

Introduction: Efforts to improve pain education and knowledge about prescription opioid misuse and opioid/substance use disorder in undergraduate medical education continue to be inadequate. To advance educational practices and address training needs to counter the opioid epidemic, we created a longitudinal pain and addiction curriculum that includes three patient vignettes in which the patient requests an early refill of opioid medication. The goal was to introduce students to the potential impact of personal biases on health care delivery and medical decision-making with patients who have pain and/or substance use disorders.

Exposure to Magnetic Fields Changes the Behavioral Pattern in Honeybees ( L.) under Laboratory Conditions.

Earth's magnetic field (MF) plays an important role for many species, including the honeybee, in navigation.
