Effects of Queen Cell Size and Caging Days of Mother Queen on Rearing Young Honey Bee Queens Apis mellifera L.

Journal of Apicultural Science, 2018
This study aims to investigate the effect of queen cell size (9.4 mm, 9.6 mm, 9.8 mm and 10.0 mm) and mother queen caged time (0 day, 2 days and 4 days) on rearing young queens without grafting larvae.

Reproductive Potential Accelerates Preimaginal Development of Rebel Workers in Apis mellifera

Animals, 2021
Rebel workers develop from eggs laid by the previous queen, before it went swarming and left the colony orphaned, until the emergence of a new queen. In contrast to normal workers developing in the queen’s presence, rebels are set to reproduce and avoid ...

Effects of Queen Rearing Technology of Apis cerana by Cutting Comb on Reproductive Capacity and Productive Performance

Agriculture
The queen, as the reproductive core of a honeybee colony, has declining reproductive capacity with age, making it necessary to rear new queens to replace older ones.

Current knowledge about behaviors of honey bee queens with highlighting of the importance future studies

Journal of Basic and Applied Zoology, 2021
Background There is one queen in each honey bee, Apis mellifera L., colony under normal conditions. This queen performs egg laying and pheromonal control in the colony. All genetic characteristics of bee workers and drones depend on the queen.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.
