Inhaled Lead Nanoparticles Enter the Brain through the Olfactory Pathway and Induce Neurodegenerative Changes Resembling Tauopathies

with Žádné komentáře

Abstract: Lead nanoparticles (PbNPs) in air pollution pose a significant threat to human health, especially due to their neurotoxic effects. In this study, we exposed mice to lead(II) oxide nanoparticles (PbONPs) in inhalation chambers to mimic real-life exposure and assess … Read More

Characterization of Heterorhabditis bacteriophora response to insect-derived and non-biological stimuli: Insights into nematode recovery and released proteins

with Žádné komentáře

Highlights: The study examines H. bacteriophora recovery to active parasitism upon host contact. Host and non-biological stimuli trigger recovery and release of secreted proteins. Secretomes of nematodes responding to various activation materials were identified. Insect materials induce the release of proteins key … Read More

Phytochemical S-methyl-L-cysteine sulfoxide from Brassicaceae: a key to health or a poison for bees?

with Žádné komentáře

Abstract: Intensive agricultural practices impact the health and nutrition of pollinators like honey bees (Apis mellifera). Rapeseed (Brassica napus L.) is widely cultivated, providing diverse nutrients and phytochemicals, including S-methyl-L-cysteine sulfoxide (SMCSO). While the nutritional impact of rapeseed on bees … Read More

Linking planar polarity signalling to actomyosin contractility during vertebrate neurulation

with Žádné komentáře

Abstract Actomyosin contractility represents an ancient feature of eukaryotic cells participating in many developmental and homeostasis events, including tissue morphogenesis, muscle contraction and cell migration, with dysregulation implicated in various pathological conditions, such as cancer. At the molecular level, actomyosin … Read More

Modeling seasonal immune dynamics of honey bee (Apis mellifera L.) response to injection of heat-killed Serratia marcescens

with Žádné komentáře

Our data demonstrate increased antimicrobial activity at transcriptional and functional levels in summer and winter workers after injection, with a stronger immune response in winter bees. On the other hand, an increase in hemocyte concentration was observed only in the … Read More

Unveiling vertebrate development dynamics in Xenopus laevis using micro-CT imaging

with Žádné komentáře

Findings This study utilized micro–computed tomography (micro-CT), a noninvasive 3-dimensional (3D) imaging technique with micrometer-scale resolution, to explore the developmental dynamics and morphological changes in Xenopus laevis. Our approach involved generating high-resolution images and computed 3D models of developing Xenopus … Read More

Characterization of Aspergillus fumigatus secretome during sublethal infection of Galleria mellonella larvae

with Žádné komentáře

Introduction: The fungal pathogen Aspergillus fumigatus can induce prolonged colonization of the lungs of susceptible patients, resulting in conditions such as allergic bronchopulmonary aspergillosis and chronic pulmonary aspergillosis. Hypothesis: Analysis of the A. fumigatus secretome released during sub-lethal infection of … Read More
