White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined.

Influence of queen mothers on the honeybee hive varroa mite population in the year 1998

open access: yesActa Agriculturae Slovenica, 1999
Varroa mite population was studied in 317 hives located in 40 apiaries in July 1998. Queens originated from 46 mother queens were reared at 16 different rearing locations in Slovenia.

Pesticide Exposure During Development Does Not Affect the Larval Pheromones, Feeding Rates, or Morphology of Adult Honey Bee (Apis mellifera) Queens

open access: yesFrontiers in Ecology and Evolution, 2021
Recent work demonstrated that honey bee (Apis mellifera L.) queens reared in pesticide-laden beeswax exhibit significant changes in the composition of the chemicals produced by their mandibular glands including those that comprise queen mandibular ...

The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

open access: yesArthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Speciation‐Controlled C–F Bond Functionalization Enabled by Zwitterionic Pnictinidenes

open access: yesAngewandte Chemie, EarlyView.
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

Efficient Methods for Rearing Strong Bee Queens

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
The aim was to choose the most efficient method to rear genetically strong queens: by overcrowding swarm or by orphaning the bees. The experiment was conducted in a private apiary in Teleorman County, between April and September 2015.

Ovipositor sources for queen-rearing of honey bee (Apis mellifera) revealed inheritable maternal effect on reared queen [PDF]

open access: yes, 2021
Abstract Queen is arguably the most important member of a honey bee colony, and queen quality is crucial for honey bee colony growth and development. In this study, queens were reared with eggs laid in queen cells (QE), eggs laid in worker cells (WE) and 2-day old larvae in worker cells (L).

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Effect of queen cell size on morphometric characteristics of queen honey bees (Apis mellifera ligustica)

open access: yesItalian Journal of Animal Science, 2022
Rearing techniques are important to determine a successful honey bee production. Queen cell cup size may affect the acceptance rate of grafted larvae and queen’s size, which in turn may influence the quality of the colonies.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...
