Antibacterial and Antioxidant Properties of Geopropolis Extracts from Stingless Bees (Meliponinae) Occurring in Brazilian Territory.

This study focuses on exploring the biological properties, antioxidant and antibacterial  associated with geopropolis resin extracts produced in Brazil. Searches were performed in the electronic databases: Lilacs, Medline, PubMed, Scielo and Science Direct. Fifteen (15) experimental studies were selected as compatible with the objective of this systematic review.

Genotoxic effects of anthropogenic environments in the leaf litter-dwelling scorpion Tityus pusillus Pocock, 1893 (Scorpiones; Buthidae).

Invertebrates are harmed by pollution of their habitats. Litter-dwelling sedentary scorpions, such as Tityus pusillus, studied here, may be good models for examining the genotoxic effects of xenobiotics in soil. Thirty specimens were collected from five sites in Northeast Brazil with different levels of human disturbance, as well as a laboratory group.

Canavalia ensiformis lectin induced oxidative stress mediate both toxicity and genotoxicity in Drosophila melanogaster.

Mannose/glucose-binding lectin from Canavalia ensiformis seeds (Concanavalin A - ConA) has several biological applications, such as mitogenic and antitumor activity. However, most of the mechanisms involved in the in vivo toxicity of ConA are not well known. In this study, the Drosophila melanogaster model was used to assess the toxicity and genotoxicity of different concentrations of native ConA (4.

Ergonomics and telework: A systematic review.

Background: Telework has been widely studied by public and private organizations; however, in ergonomics, studies that focused on this topic are still sporadic.

Objective: Thus, this article endeavours to systematize the qualified scientific research related to ergonomics and teleworking to determine the main benefits and disadvantages and to identify the main issues addressed by authors.

Methods: A thorough research was conducted in the Scopus/Embase and Web of Science databases for this review.
