2. Development and validation of a high-performance thin layer chromatography method for the simultaneous quantitation of α- and γ-mangostins in Thai stingless bee propolis
ABSTRACT Stingless bees (Apoidea) are widely distributed and commercially cultivated in artificial hives in fruit gardens. Their propolis are commonly used in traditional medicine to treat various diseases (e.g., abscesses, inflammations, and toothaches) and as a constituent of numerous health products. Thus, this study aimed to (i) develop and validate a hi

3. Prevalence of dermatoses in dermatologic evaluation requests from patients admitted to a tertiary hospital for 10 years
AbstractSkin diseases are common in hospitalized patients. However, there is a lack of data concerning their frequency. The objective of this study is to evaluate the prevalence of dermatological diagnoses in hospitalized patients after consultation requested by nondermatologist physicians to the Department of Dermatology, Hospital de Clinicas de Porto Alegr

4. Propolins and glyasperin A from stingless bee nests
Abstract Chemical investigation of the dichloromethane extracts of the propolis collected from bee (Tetragonula biroi Friese) hives in San Roque, Sorsogon, Philippines afforded propolin A (1), propolin E (2), propolin H (3), glyasperin A (4), squalene, a mixture of lupeol, α-amyrin and β-amyrin, and another mixture of urs-12-en-3-one, olean-12-en-3-one and

5. Pollen analysis of honey and beebread derived from Brazilian mangroves
Pollen analyses were performed on honey and beebread from hives in apiaries located in two distinct mangrove areas dominated by Laguncularia racemosa (L.) C.F. Gaernt. One apiary was located at the edge of Guanabara Bay, Rio de Janeiro State, and the other near Maranguá Bay, Bahia State, Brazil. We investigated the contribution of nectar and pollen from man

6. A CADEIA DE PRODUÇÃO DO MEL NO RIO GRANDE DO SUL: A ORGANIZAÇÃO E A GOVERNANÇA NAS TRANSAÇÕES DOS APICULTORES ASSOCIADOS À APISMAR / HONEY PRODUCTION CHAIN IN RIO GRANDE DO SUL: THE ORGANIZATION AND GOVERNANCE IN THE TRANSACTIONS OF APISMAR BEEKEEPERS
This study aims to determine the organization and governance in the transactions of APISMAR beekeepers and describe the honey production chain in Rio Grande do Sul. It is used as a theoretical framework the concept of agroindustrial production chain, the structure-conduct-performance paradigm (SCP), and the theory of transaction cost economics (TCE). The res

7. Inhibition of Saccharomyces cerevisiae Pdr5p by a natural compound extracted from Brazilian Red Propolis
Multidrug resistance of cancer cells and pathogenic microorganisms leading to the treatment failure of some forms of cancer or life-threatening bacterial or fungal infections is often caused by the overexpression of multidrug efflux pumps belonging to the ATP-binding cassette transporters superfamily. The multidrug resistance of fungal cells often involves t

9. Sistema de Informações Geográficas destinado ao planejamento da atividade apícola no assentamento Padre Josimo Tavares- PA / Geografic Information System for the planning of the apicultural activity in Padre Josimo Tavares Settlement - PA
Today, apiculture is economically exploited by the man in the pollination of crops, as well as the production of propolis, royal jelly, bee venom and the best known and exploited by the man, the honey. Apiculture has been established as one of the most important activity in terms of economic, social and environmental, once employing family labor-intensive an

10. Avaliação do mel como substrato para contaminação fúngica no ambiente da colméia. / Evaluation of honey as a substrate for fungal contamination in the environment of the hive.
Honey is a food produced by bees from the nectar of flowers collected and processed by the digestive enzymes of insects, stored in combs in their hives to serve them food. The Brazilian apiculture (branch of agriculture that studies of honey bees) has suffered high losses of honey bees, due to a number of diseases that affect the hives, putting them at risk.

11. Influência das precipitações pluviométricas e da atividade forrageira das abelhas africanizadas (Apis mellifera L.) no comportamento higiênico / Influence of rainfall and foraging activity on hygienic behavior of Africanized honey bees (Apis mellifera L.)
Hygienic behavior (HB) of honey bees (Apis mellifera ) is a useful and selectable characteristic for resistance to diseases. However, in order to efficiently evaluate and select for this behavior we need to understand the mechanisms involved and how environmental factors influence HB. We examined how time of the day, bee age and behavioral ontogeny, and clim

12. Identificação da flora microbiana em colméias de meliponina
The bees of Meliponina, also known as Indians bees without sting, are in various tropical regions. They execute functions, like: polinization of fanerogams, production of honey, wax and propolis and the collection of pollen. Moreover, they contribute for the Biologys applications, especially in Genetic and Evolution and they also can be utilized as didactic
