Vitellogenins Level as a Biomarker of the Honeybee Colony Strength in Urban and Rural Conditions [PDF]
InsectsThe study aimed to verify whether urban beekeeping affects the strength of the honeybee (Apis mellifera) colonies from urban apiaries and the variability of the crucial for their health and long-life protein—vitellogenins.

Research Note: Integrated proteomic analyses of chicken egg yolk granule [PDF]
Poultry Science, 2023 : Chicken egg yolk granules (EYG) were the precipitated component of egg yolk after water dilution and centrifugation. Compared with egg yolk, EYG are rich in proteins, phospholipids, and minerals.

Blood-feeding adaptations and virome assessment of the poultry red mite Dermanyssus gallinae guided by RNA-seq [PDF]
Communications Biology, 2023 Dermanyssus gallinae is a blood-feeding mite that parasitises wild birds and farmed poultry. Its remarkably swift processing of blood, together with the capacity to blood-feed during most developmental stages, makes this mite a highly debilitating pest ...

Endomitosis controls tissue-specific gene expression during development.
PLoS Biology, 2022 Polyploid cells contain more than 2 copies of the genome and are found in many plant and animal tissues. Different types of polyploidy exist, in which the genome is confined to either 1 nucleus (mononucleation) or 2 or more nuclei (multinucleation ...
