Effect of Number of Worker Bees in Queen Mating Nucleus on Queen Quality and Mating Nucleus Population Dynamics

open access: yesBee Studies- Apiculture Research Institute, 2020
This study aims to investigate the effects of the amount of worker bees placed into the mating nucleus on queen quality parameters and nucleus population dynamics. The quantity of 80(g) (~700 workers) that mating nucleus made of Kirchhain-model can contain has been based on.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

open access: yesFEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

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

open access: yesAnnals 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.

Histological Estimates of Ovariole Number in Honey Bee Queens,Apis mellifera, Reveal Lack of Correlation with other Queen Quality Measures [PDF]

open access: yesJournal of Insect Science, 2011
Published estimates of the number of ovarioles found in the ovaries of honey bee, Apis mellifera L. (Hymenoptera: Apidae) queens range from 100 to 180 per ovary. Within the context of a large-scale study designed to assay the overall quality of queens obtained from various commercial sources, a simple histology-based method for accurate determination ...
