Desintegrinas de Bothrops alternatus: biologia molecular, estudos in vitro, in vivo e bioinformática estrutural.
(Universidade Federal de São Carlos, 2005-11-28)
Disintegrins are toxins frequently found in snake venoms. Their biological
effects are due to their binding to cell receptors known as integrins. Aiming to isolate
new disintegrins from Bothrops alternatus snake, a cDNA ...
Estudo in vitro de cito e fototoxicidade das drogas nitroheterocíclicas Nitracrina e Quinifuryl
(Universidade Federal de São Carlos, 2005-03-09)
The cytotoxicity of two nitroheterocyclic compounds, Polish antitumor agent, Nitracrine and Russian antiseptic, Quinifuryl, towards three lines of cells were determined under normoxia conditions. Special emphasis has been ...
Análise da expressão da metalotioneína em duas espécies de peixes, Oreochromis niloticus e Prochilodus lineatus
(Universidade Federal de São Carlos, 2008-04-18)
Metallothioneins (MT) are non enzymatic proteins with with metal-binding ability. It has been
used as a biomarker for environmental pollution by the analysis of its expression in several fish
species. The tilapia is a ...
Contribuição citogenética à análise da biodiversidade em Astyanax fasciatus (Pisces, Characidae).
(Universidade Federal de São Carlos, 2005-03-10)
Astyanax fasciatus is characterized as a cytogenetically diverse species. Sympatric and
syntopic occurrence of distinct cytotypes corroborates the hypothesis that A. fasciatus might
represent a species complex sharing a ...

(Universidade Federal de São Carlos, 2018-10-19)
Genetic studies of natural populations have long been helping the scientific community and society in general to understand the evolution and conservation of both environments and communities. These studies have helped to ...
Origem e diferenciação do sistema de cromossomos sexuais ZZ/ZW em Triportheus (Characiformes, Characidae): citogenética, mapeamento dos genes ribossomais e microdissecção cromossômica
(Universidade Federal de São Carlos, 2007-04-27)
Chromosomes of distinct species of Triportheus (Characiformes, Characidae) from different hydrographic basins in Brazil, as well as in Argentina, were analyzed in the present work. Triportheus nematurus, from Piracicaba ...
Cistatinas recombinantes de cana-de-açúcar : especificidade, produção em biorreator e conservação por liofilização
(Universidade Federal de São Carlos, 2018-03-02)
Phytocystatins are inhibitors of cysteine peptidases found naturally in plants.
Sugarcane cystatins are distinguished by their high inhibitory activity and possible
biotechnological applications. In this work, a comparative ...

(Universidade Federal de São Carlos, 2019-03-01)
Fish are animals present in a wide variety of habitats and are distributed all over the world. The diversity of forms, behaviors and niches associated with the evolutionary characteristics of these animals make them important ...
Estudo de vias alternativas aos sistemas LiaFSR e YycFGHIJ que levam à diminuição da sensibilidade à daptomicina em Enterococcus faecium
(Universidade Federal de São Carlos, 2018-08-21)
Enterococcus is one of the most important multi-drug resistant nosocomial pathogens. Infections caused by vancomycin resistant Enterococci (VRE) are becoming increasingly difficult to treat, often with prolonged hospital ...
