Avaliação dos lipídeos de membrana e das ORF s dos contratransportadores Na+/H+...
Assis, Priscilla Anne Castro deSoil saliniy is a major factor in reducing plant growth and, consequently, their agricultural productivity. Most of the studies in the literature presents a strategy for reducing the effects of improving salt tolerance in plants for the production of osmolytes and stress proteins, and there are few studies aimed at increasing salt tolerance by restoring ionic homeostasis. This work was proposed to understand th...
Análise estrutural do domínio de reconhecimento a carboidratos da lectina Dvirl...
Nóbrega, Raphael Batista daLectins are defined as proteins or glycoproteins of nonimmune origin that have at least one site of reversible binding to carbohydrates or glycoconjugates. Lectins of plant origin are the most studied and characterized as three-dimensional structure and biological functions related. Lectins can be found in different parts of the plant from its root to the interior of the seeds. In this last are found where the ...
Produção de lipases e biossurfactantes por bactérias isoladas de um solo contam...
Carvalho, Laís Campos Teixeira deThe lipases and biosurfactants produced by microorganisms are involved in the metabolism of oil substrates and they receive great biotechnological interest. In this work the production of lipases and biosurfactants by bacteria isolated from soil used for discard of the residual vegetable oil was analyzed. The 66 strains tested demonstrated lipolytic activity on the tributirine agar. In the rhodamine B agar medi...
Isolamento e caracterização fenotípica e molecular de parasitos Leishmania sp. ...
Rodrigues, Yara Kátia SantosLeishmaniasis is a complex of infectious and parasitic diseases endemic in 88 countries, that constitute a serious public health problem. Several species of the genus Leishmania are the causative agents of disease, among them the species L. (V.) braziliensis associated with different clinical manifestations of American Cutaneous Leishmaniasis (ACL). In the present study were obtained nine isolates of Leishmania...
Análise do perfil de metilação dos genes THBS1, GPX3 e COX2 e identificação de ...
Melo, Cynthia Farias Vieira deCancer is a disease with a high mortality rate in Brazil, including, stomach cancer is currently the fourth most common type of cancer worldwide, responsible for countless deaths. Its etiology is multifactorial, because studies suggest associations to various factors such as dietary habits, environmental factors, genetic and epigenetic factors and gastric infection by Helicobacter pylori. Epigenetic changes suc...
Isolamento, purificação e atividades biológicas de uma nova lectina de sementes...
Farias, Daniel Lima deIn many parts of the world leguminous plant is one of the most widely known plants previously reported. There are many different types of plants in the family leguminous used as food, in this case, the genus Canavalia comprises a group of some 48 species. The term lectin (derived from the latin word legere, meaning, among other things, to select) represent a heterogeneous group of proteins ranging from size, st...
Efeitos de furocumarinas associadas à luz ultravioleta B (312mn) em staphylococ...
Silva, Emanuelle Batista Felismino daFurocoumarins (FCs) are an important class of photoactive compounds which may potentially bind to DNA forming intermolecular complexes, and once excited by UVA light (~ 365 nm) they re able to form photoadducts, which may result in mutagenicity and lethality. However, when the 8-methoxypsoralen (8-MOP) is added to the post-irradiation plating medium increases the sensitization probably by inhibiting repairs in ...
Caracterização bacteriológica da água do mar e diversidade de bactérias cultivá...
Araujo, Gilmara HenriquesBacteria play a fundamental role in the health of corals. The interest in the study of microorganisms associated with corals has increased since the confirmation that they can be pathogenic or mutualistic. In the coastal reefs of the State of Paraiba the cases of the pigmentation changes of scleractinian Siderastrea stellata, that probably occurs in the process of coral bleaching, are observed. The aim of this ...

Santos, Jonathas Diego LimaBrazil is the country with the highest rate of reported snakebites. The venomous snakes that occur in the country belong to the Viperidae and Elapidae families. Snakebites cause the release of pharmacologically active substances with local effects such as hemorrhage, oedema, necrosis, myotoxicity, cardiotoxicity, neurotoxicity and cytotoxicity, as well as systemic effects such as blood coagulation, spontaneous ...
Estrutura cristalográfica da lectina de sementes da Canavalia maritima Aub, em ...
Silva Filho, José Caetano daPlants are sessile organisms susceptible to biotic and abiotic stresses. Insect herbivore attacks are factors that affect their survival and development. To defend themselves, plants produce and release chemical compounds, such as non protein amino acids, that negatively affect the development processes of their attackers, as well as use phytohormones that regulate defense responses against herbivory. In the pr...
