King George Island is the largest island and the principal area used for research bases in Antarctica. Argentina, Brazil, Chile, China, Poland, Russia, South Korea and Uruguay have permanent open…
Distribution and Interaction Patterns of Bacterial Communities in an Ornithogenic Soil of Seymour Island, Antarctica
Next-generation, culture-independent sequencing offers an excellent opportunity to examine network interactions among different microbial species, and reveals the existence of a unique pattern of interactions in which the soil microbial network formed a clustered topology, rather than a modular structure as is usually found in biological communities.
FUNGOS MUSCÍCOLAS NA ILHA ELEFANTE - ANTÁRTICA
Os fungos muscicolas ainda sao pouco conhecidos para a Antartica, tanto em sua taxonomia quanto na ecologia. No sentido de identificar as especies ocorrentes em Stinker Point – Ilha Elefante –…

Eugenia uniflora leaves essential oil induces toxicity in Drosophila melanogaster: involvement of oxidative stress mechanisms
A phytochemical fingerprinting was performed and the toxicity induced by the Eugenia uniflora leaves essential oil in a Drosophila melanogaster model was evaluated, finding an oxidative stress response signaling, evidenced by changes in ROS production, lipid peroxidation, alterations in the activity of antioxidant enzymes and expression of Nrf2 protein targets occurred.
