Queen honey bees exhibit variable resilience to temperature stress
PLoS ONE, 2021 Extreme temperature exposure can reduce stored sperm viability within queen honey bees; however, little is known about how thermal stress may directly impact queen performance or other maternal quality metrics.

Cryptic "royal" subfamilies in honey bee (Apis mellifera) colonies. [PDF]
PLoS ONE, 2018 During emergency queen rearing, worker honey bees (Apis mellifera) select several otherwise worker-destined larvae to instead rear as candidates to replace their dead or failing queen.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017 BackgroundIn cardiac resynchronization therapy (CRT), quadripolar (QUAD) left ventricular (LV) leads are less prone to postoperative complications than non‐QUAD leads. Some studies have suggested better clinical outcomes.

Honey bee queen health is unaffected by contact exposure to pesticides commonly found in beeswax
Scientific Reports, 2021 Honey bee queen health is crucial for colony health and productivity, and pesticides have been previously associated with queen loss and premature supersedure.

Direct assessment of queen quality and lack of worker suppression in a paper wasp [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2005 Assessing a conspecific's potential is often crucial to increase one's fitness, e.g. in female choice, contests with rivals or reproductive conflicts in animal societies. In the latter, helpers benefit from accurately assessing the fertility of the breeder as an indication of inclusive fitness.

Effect of amino acids on quality evaluation of alfalfa hay
Siliao yanjiu, 2022 The experiment was to explore effect of amino acids on quality evaluation of alfalfa hay. The yield (CL), nutritional quality and 17 amino acids contents of alfalfa of different varieties (Queen, WL319HQ and Bara310SC) were measured and comprehensively ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Row-column response surface designs
, 2003 Factorial experiments are widely used in industry to investigate the effects of process factors on quality response variables. Many food processes, for example, are not only subject to variation between days, but also between different times of the day ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

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.
