Genes e variantes genéticas na regulação da eficiência alimentar de gado Nelore
(Universidade Federal de São Carlos, 2019-05-08)
Feeding accounts for most of the costs in beef cattle production. To reduce it, as well as the environmental impact, greenhouse gas emission, and land occupation have been mandatory to improve the animal feed efficiency. ...
Toxicidade aguda e respostas metabólicas e hematológicas do pacu (Piaractus mesopotamicus, Holmberg, 1887) exposto a concentração sub-letal de triclorfon e recuperação
(Universidade Federal de São Carlos, 2010-05-28)
Parasitosis in fishes is a relevant problem in aquaculture. Besides, the organophosphate trichlorfon (2,2,2-trichloro-1-hydroxyethyl phosphonate) is amongst the most used medicine in farming of fishes. Due to trichlorfon ...
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 ...
Variação gênica e estrutura populacional de Euglossa cordata (Linnaeus, 1758) acessadas por meio de marcador mitocondrial e locos microssatélites
(Universidade Federal de São Carlos, 2018-07-10)
Orchid bees (Apidae, Euglossini) are important Neotropical pollinators. Two main features characterize these species: the tongue, which reaches at least half the body length, enabling the search for food resources in ...
Produção heteróloga e caracterização de uma beta-glicosidase identificada em sequências metagenômicas de um lago da região amazônica
(Universidade Federal de São Carlos, 2017-02-15)
Metagenomics studies allow the direct analysis of a genetic material in an
environmental sample and when linked to bioinformatics it gives a powerful tool to explore the
role of new genes and proteins not studied before. ...
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 ...
Subclonagem e expressão do domínio catalítico da jararagina: estudo do efeito das modificações pós-traducionais na atividade hemorrágica.
(Universidade Federal de São Carlos, 2004-04-23)
Metalloproteases are Zn++-dependent peptidase enzymes, richly found in Crotalidae and Viperidae snake venoms. Most snake venom metalloproteases (svMPs) are active on extracellular matrix components and this effect is thought ...
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 de genes e proteínas envolvidos no estado redox de reticulócitos e eritrócitos de pacientes beta talassêmicos ou com anemia falciforme
(Universidade Federal de São Carlos, 2018-06-27)
Although not the primary etiology of diseases such as beta-thalassemia and sickle cell anemia, oxidative damage plays a crucial role in the aggravation of these diseases, contributing to the hemolysis and the short survival ...
Efeitos de uma desintegrina recombinante de Bothrops alternatus, DISBA-01, em células precursoras miogênicas (CPM)
(Universidade Federal de São Carlos, 2009-09-21)
Disintegrins are toxins commonly found in snake venoms whose biological effects occour upon interaction with surface receptors known as integrins. DisBa-01, an RGD disintegrin isolated from a cDNA library made with mRNAs ...
