1. Honeycomb: a template for reproducible psychophysiological tasks for clinic, laboratory, and home use
Objective: To improve the ability of psychiatry researchers to build, deploy, maintain, reproduce, and share their own psychophysiological tasks. Psychophysiological tasks are a useful tool for studying human behavior driven by mental processes such as cognitive control, reward evaluation, and learning. Neural mechanisms during behavioral tasks are often stu

2. Resorcinolic Lipids from Yucatecan Propolis
Propolis is a material produced by bees from a combination of plant exudates and wax, used to fill out cracks in the beehive and to defend against intruders and pathogenic microorganisms; it is recognized for its many biological activities and its chemical composition depends on the botanical sources close to the beehive. The objective of this investigation

4. Flavonoids, phenolic content, and antioxidant activity of propolis from various areas of Guanajuato, Mexico
Abstract Propolis is a resin gathered by honey bees from trees and shrubs but it used in the beehive as building material or as an antibiotic paste. The aim of this study was to determine the content of flavonoids and phenols, as well as the antioxidant capacity of propolis from various regions of Guanajuato, Mexico. The content of flavonoids and phenols wa

5. Essential minerals and inorganic contaminants (barium, cadmium, lithium, lead and vanadium) in dried bee pollen produced in Rio Grande do Sul State, Brazil
Abstract Like other beehive products, such as honey, royal jelly and propolis, bee pollen has attracted great interest because of the health benefits it can provide when consumed. Bee pollen has high contents of sugars and proteins and a low content of lipids, it is also a rich source of vitamins and other bioactive compounds, which makes it an attractive mi

7. Isolation and identification of formononetin of João Pessoa-PB-Brazil red propolis, seasonal studies and evaluation of their biological activities / Isolamento e identificação de formononetina da propolis de João Pessoa - PB, estudo de sua sazonalidade e avaliação de suas atividades biologicas
Propolis is a resinous substance produced by the honeybee Apis mellifera. Bees use propolis to seal holes and to protect the beehive. To produce propolis the honeybee uses resins of leaf buds and buds, resinous exudates and other parts of plant tissues. Propolis is used as a folk medicine since 3000 BC. Numerous biological properties have been found includin

9. Characterization of red propolis : its botanical origin and the seasonal effect on its chemical composition and biological activity / Caracterização da propolis vermelha : sua origem botanica e o efeito sazonal sobre sua composição quimica e atividade biologica
Among the Brazilian propolis, new propolis not yet classified, according to Park et al., 2002 and called of red propolis, originary from Alagoas state (Northeast of Brazil), have showed interesting results in preliminary studies in our laboratories. Thus, the main objective of this work is to identify the botanical marker of red propolis, the chemical compos

10. DESENVOLVIMENTO DE METODOLOGIA PARA ANÁLISE DE SULFONAMIDAS EM MEL UTILIZANDO CROMATOGRAFIA LÍQUIDA E DETECÇÃO POR ARRANJO DE DIODOS / DEVELOPMENT OF METHODOLOGY FOR ANALYSIS SULFONAMIDES IN HONEY USING LIQUID CHROMATOGRAPHY AND DETECTION DIODE ARRAY
Honey is a natural substance produced by bees and by your nature it is considered a healthy product. Presence of additives and/or preserve agents is not permitted. On apiculture, sulfonamydes are largely used on prevention and control of beehive disease, such as American foulbrood caused by Paenibacillus larvae. A consequence of this practice is the presence
