Differential performance of honey bee colonies selected for bee-pollen production through instrumental insemination and free-mating technique
Provedor de dados: 45
Autores: Mattos,I.M. de; Souza,J.; Soares,A.E.E.
ABSTRACT The use of bee-pollen as a nutritional supplement or as a production-enhancing agent in livestock has increased the demand for this product worldwide. Despite the current importance of this niche within the apiculture industry, few studies have addressed the pollen production. We tested the performance of free-mated (FM) and instrumentally inseminated queens (IQ) in order to establish the effect of different breeding systems on pollen production. The F1 generation of IQ queens produced 153.95±42.83g/day, showing a significant improvement on the pollen production (2.74 times) when compared to the parental generation (51.83±7.84g/day). The F1 generation of free-mated queens produced 100.07±8.23 g/day, which increased by 1.78 times when compared to...

Analysis of the effects of climate variables on Apis mellifera pollen foraging performance
Provedor de dados: 45
Autores: Mattos,I.M. de; Souza,J.; Soares,A.E.E.
ABSTRACT Pollination services performed by bees are essential for the reproduction of a great part of flowering plants. The pollen collected by Apis mellifera while performing pollination (bee pollen), has been incorporated into the human diet for its favorable nutritional components. Around 1,500 tons of bee pollen are produced annually worldwide, especially in Spain, China, Australia, Argentina, and Brazil. Despite the importance of bee pollen within apiculture, little is known about the effects of climate variations on bee pollen collection and production. We monitored the pollen collection performance of 24 different honey bee colonies in different climate conditions within a period of one year. We then analyzed the statistical interaction among the...

Effects of artepillin C on model membranes displaying liquid immiscibility
Provedor de dados: 56
Autores: Pazin,W.M.; Vilanova,N.; Voets,I.K.; Soares,A.E.E.; Ito,A.S.
It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. To test this hypothesis, we investigated the effects of the major compound of green propolis, artepillin C, on model membranes (small and giant unilamelar vesicles) composed of ternary lipid mixtures containing cholesterol, which display liquid-ordered (lo) and liquid-disordered (ld) phase coexistence. Specifically, we explored potential changes in relevant membrane parameters upon addition of artepillin C presenting both neutral and deprotonated states by means of small angle X-ray scattering (SAXS), differential scanning calorimetry...
