(Universidade Federal de São Carlos, 2005-01-04)
Commercial fish farming has been viable for industry in Brazil. National production is around 120 thousand tons/year. In this way, large amount of fishes are handled every day in our farms. However, drastic consequences ...
Caracterização genética do pirarucu Arapaima gigas (Cuvier) (Teleostei, Osteoglossidae) da bacia Tocantins-Araguaia, estado do Mato Grosso.
(Universidade Federal de São Carlos, 2003-08-29)
In South America the osteoglossiforms are represented by the Arapaima and the Osteoglossum sorts, which are mostly found in the Amazonic basin, Tocantins Araguaia. There are virtually no genetic studies on this group, ...
Variabilidade genética em populações de Jabiru mycteria (Lichtenstein, 1819) e Mycteria americana (Linneaus, 1758) (Aves, Ciconiidae): fluxo gênico e filogeografia
(Universidade Federal de São Carlos, 2006-06-07)
This study evaluates the levels of variability, genetic structure, and phylogeographical
patterns of wild populations of Jabiru Storks (Jabiru mycteria) and Wood Storks (Mycteria
americana). These species belong to the ...
Diversidade de peixes residentes em cabeceiras de rios. Uma abordagem cromossômica em três diferentes biomas aquáticos da Região Sul do Brasil
(Universidade Federal de São Carlos, 2006-11-10)
This study presented cytogenetic analysis of small fishes species collected in the headwaters of Jaguariaíva, Ribeira and, Tibagi rivers. Some of these species have had a comparative cytogenetic population analysis among ...
Estrutura genética e sociogenética das populações e ninhos de Euglossini (Hymenoptera: Apidae) determinadas por meio de microssatélites
(Universidade Federal de São Carlos, 2007-07-04)
Euglossine bees are important pollinators of many Neotropical plant species, particularly orchids which could present a species-specific bee-flower relationship, essential to the reproductive success of these plants. Orchids ...
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 ...
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 do efeito da Alternagina-C, uma desintegrina do veneno de Bothrops alternatus,sobre a adesão de células normais e tumorais. Avaliação do seu potencial como agente anti-metastático.
(Universidade Federal de São Carlos, 2004-11-26)
The α2β1 integrin is a major collagen receptor that plays an essential role in the
normal and tumor cells adhesion to the extracellular matrix, as well as in the
metastasis. Antagonists of integrins have 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 ...
