Caracterização das interações químicas entre os microrganismos simbiontes das formigas cortadeiras
(Universidade Federal de São Carlos, 2021-01-13)
The complex symbiosis in Attini ant nests inspires curiosity in different fields of research from Microbiology to Chemical Ecology. These ants cultivate their mutualist fungus for approximately 50 million years in structures ...
Co-cultivo fúngico como estratégia para obtenção de metabólitos biologicamente ativos
(Universidade Federal de São Carlos, 2021-02-23)
In this work, the bactericidal, antiprotozoal, and inhibition of cathepsin V proteolytic activity of extracts from the axenic cultivation of six fungal species (Fusarium guttiforme, Pestalotiopsis diospyri, Phoma ...
Avaliação in vitro da ação fotodinâmica antimicrobiana e antitumoral do complexo cis-[Ru(phen)2(pPDIp)]2+
(Universidade Federal de São Carlos, 2021-02-19)
Photodynamic therapy (PDT) activates a photosensitizer by visible or infrared light to generate cytotoxic oxygen species that lead to cell death. PDT is generally used in applications in superficial lesions and can be used ...
Imagens espectrais do processo de agregação da insulina por complexos metálicos luminescentes
(Universidade Federal de São Carlos, 2021-03-01)
Insulin is a protein hormone synthesized by β cells in the pancreas, which regulates the level of glucose in the blood. This protein was the first biopharmaceutical produced on an industrial scale for the treatment of ...
Síntese de complexos de Mg(II), atividade antioxidante e citotóxica
(Universidade Federal de São Carlos, 2021-03-09)
The objective of this work was to develop metal complexes containing natural products that have antioxidant activity to be applied in the cosmetics sector. For that, 3 [Mg(phen)2PN]+ metal complexes were synthesized and ...
Evaluation of the biological activity of the disintegrin-like and cysteine-rich domains of Bothropasin, a metalloproteinase from Bothrops jararaca
(Universidade Federal de São Carlos, 2021-05-17)
Bothropasin is a 48kDa hemorrhagic class III Snake Venom Metalloproteinase (SVMP). As a multi-domain protein, it contains catalytic metalloproteinase (M), disintegrin-like (D), and cysteine rich domains (C). Integrins ...
Determinação de Si e Y em amostras agronômicas por espectrometria de emissão óptica com plasma induzido por micro-ondas
(Universidade Federal de São Carlos, 2021-05-20)
Different demands for analytical responses are presented in agricultural research. In this approach, this dissertation, divided into two chapters, seeks to offer analytical alternatives for plant breeding and fish nutrition ...
Eletrodo de pasta de carbono modificado com solvente eutético profundo hidrofóbico e sua aplicação voltamétrica
(Universidade Federal de São Carlos, 2021-03-01)
In this work, the use of hydrophobic deep eutectic solvent was proposed for the modification of carbon paste electrodes. Different HDES were prepared using fatty acids: octanoic, decanoic, and dodecanoic acids, and ...
