Multifunctional Bioactive Coatings Based on Bioglass, Vitamin D3, and Melittin Deposited via MAPLE for Enhanced Osseointegration, Antibacterial Activity, and Corrosion Resistance of Titanium Implants

Advanced Materials Interfaces, EarlyView.
Matrix‐Assisted Pulsed Laser Evaporation (MAPLE) technique is used to cover titanium (Ti) substrates with multifunctional bioactive coatings composed of bioglass, vitamin D3, and melittin. Coatings exhibited excellent chemical integrity and favorable micro/nanostructured morphology (promoting cellular adhesion and viability), and a sustained release of

In-vitro bioaccessibility of antioxidant properties of bee pollen in Turkey

Food Science and Technology, 2020
Pollen, which is a valuable food source for bees and bee larvae, is the product of the male reproductive cells of flowering plants. Flower pollen powder sticks to the whole body of worker bees while strolling (Borycka et al., 2015).

The colony environment modulates sleep in honey bee workers [PDF]

Journal of Experimental Biology, 2014
Abstract One of the most important and evolutionarily conserved roles of sleep is the processing and consolidation of information acquired during wakefulness. In both insects and mammals, environmental and social stimuli can modify sleep physiology and behavior, yet relatively little is known about the specifics of the wake experiences ...

Strong and Weak Coupling Nanophysics with Free Electron Beams

Advanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.

Identification of Volatile and Protein Profiles in the Sting and Mandibular Glands of the Worker Honey Bee (Apis cerana indica)

, 2013
In social insect, the perception of volatile molecules, odorants and releasing pheromones, is mediated via specialized olfactory organs is generally thought to be accomplished by odorant-binding proteins and pheromonecarrying proteins.

Hemp Proteins Conjugated with Green Tea Polyphenol Extract Form De Novo Plant‐Sourced Emulsifiers Suitable for Nanodelivery Systems Bearing Lipophilic Psychopharmaceuticals

Advanced Therapeutics, EarlyView.
Green tea polyphenols, conjugated either covalently or non‐covalently to hemp protein, comprise an excellent stabilizing matrix for oxidatively‐sensitive small molecules. These nanoemulsions are highly stable to a variety of chemical and physical stressors, protecting the small molecule while allowing for easy uptake across cell membranes and rapid ...
