6. Physicochemical characteristics and fibril-forming properties of collagen from paddlefish (Polyodon spathula) and globefish (Fugu flavidus) skin byproducts
Abstract Acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC) from the skin byproducts of paddlefish (ASC-P and PSC-P) and globefish (ASC-G and PSC-G) were purified and characterized. The imino acid contents of ASC-P, PSC-P, ASC-G and PSC-G were 194.1, 197.9, 186.4 and 189.7 residues/1000 residues, respectively. SDS-polyacrylamide gel electrophoresi

8. Desenvolvimento e aplicação de técnicas miniaturizadas de preparo de amostra na determinação de fármacos no ambiente / Development and application of microextraction sample preparation techniques to determine pharmaceutical drugs in the environment
The occurrence of pharmaceutical drugs in the environment is a worldwide problem caused by the genotoxicity and ecotoxicity activities of those compounds. Water is one of most used natural resource in human activities which explain the presence of emerging contaminants. Those compounds affect not only humans but also aquatic animals that spend the whole life

12. Produção e análise de metabólitos secundários de fungos filamentosos
Filamentous fungi produce a diverse array of secondary metabolites that have a remarkable impact on society. Some metabolites are exploited for their antibiotic and pharmaceutical activities, other are involved in diseases, due to the fungi interactions with plants or animals. In this context, the goal of this work was the obtention of secondary metabolites
