Portuguese propolis disturbs glycolytic metabolism of human colorectal cancer in vitro ; Propolis is a resin collected by bees from plant buds and exudates, which is further processed through the activity of bee enzymes. Propolis has been shown to possess many biological and pharmacological properties, such as antimicrobial, antioxidant, immunostimulant and antitumor activities. Due to this bioactivity profile...

Taxonomia de podcasts : da criação à utilização em contexto educativo

Este artigo apresenta a taxonomia de podcasts desenvolvida no âmbito do projecto "Implicações pedagógicas da utilização de podcasts em blended-learning". Os estudos, realizados na Universidade do Minho ao longo de três semestres, envolveram 6 docentes e 479 alunos. Os podcasts mais usados são os informativos, que permitem diversas finalidades e foram produzidos pela maior parte dos autores participantes no estu...

Evaluation and characterization of antioxidant and antigenotoxic properties of ...

Propolis is a substance produced by bees (Apis mellifera L.) after harvest of buds and bark of plants and by subsequent mixing with the salivary enzyme β-glucosidase. Bees use propolis in their combs as protection, to repair damage, to build aseptic locals for the eggs of the queen, and also as a thermal insulator. The composition of propolis varies geographically, with the available flora, the time of collecti...

Herbicidal properties of portuguese propolis samples

Propolis is a natural product made by honeybees (Apis mellifera L.) with important physical and biological protective functions, being used to maintain hive integrity, as well as adequate thermal and sanitary conditions. It is a complex mixture made essentially from collected plant exudates, being composed of waxes, resins, balsams, pollen, essential oils, and other organic and mineral compounds. It has a high ...

Search for portuguese propolis antimicrobial activity in a wide range of microo...

Propolis is a bee product composed by several compounds such as waxes, resins, essential oils and other organic compounds. Over the last decades, several studies have shown a wide range of biological and pharmacological properties for propolis from different provenance. Due to this large spectrum of bioactivities, such as antimicrobial, antioxidant, anti-inflammatory, and antitumor, among others, this product c...

Bioactivities of portuguese propolis

Natural products have been traditionally used in the treatment of several diseases because they are the source of many biologically active compounds, which can bear several therapeutic actions and/or constitute models for the synthesis of new drugs. Propolis or bee glue, one of the few natural remedies that has maintained its popularity over a long period of time, has been the focus of intense research during t...

A new method for testing antimicrobial activity of filamentous fungi

Attractivity of omnivore, carnivore and herbivore mammalian dung to Scarabaeina...

In this study, performed in a remnant of Brazilian Atlantic Forest, three types of dung from animals with distinct alimentary habits were utilized, in order to verify possible differences of attractivity of these dungs to the Scarabaeinae and the influence of seasonality in the attractivity. Three habitats were sampled: edge, clearing and forest core, each with 40 pitfall traps. A total of 2,137 beetles were co...

Impact of podcasts in teachers education : from consumers to producers

Podcasts are being used in higher education, particularly in blended-learning or in distance learning. Studies in different universities have reported its use with different purposes. The research described in this paper reports to a study conducted in Portugal in three courses, one of a teaching program of Biology and the other two of Educational Master programs. The students (n= 82) liked the podcasts and sho...
