1. Highlights in the knowledge of brown spider toxins
Abstract Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function. The signs and symptoms observed following a brown spider bite are called loxoscelism. Brown spi

2. Endogenous phospholipase A2 inhibitors in snakes: a brief overview
Abstract The blood plasma of numerous snake species naturally comprises endogenous phospholipase A2 inhibitors, which primarily neutralize toxic phospholipases A2 that may eventually reach their circulation. This inhibitor type is generally known as snake blood phospholipase A2 inhibitors (sbPLIs). Most, if not all sbPLIs are oligomeric glycosylated proteins

3. Structure and histochemistry of medicinal species of Solanum
ABSTRACT Studies on native medicinal plants strengthen initiatives to preserve the environments where those species naturally occur, many of them already strongly menaced even before their potential to humankind is known. Root and stem barks, leaves, and pericarps samples of Solanum agrarium Sendtn., S. lycocarpum A. St.-Hil., S. palinacanthum Dunal, S. pani

4. Investigações estruturais dos domínios funcionais das miosinas classes VIII e XI presentes em plantas / Structural investigations of the functional domains of plant myosins (classes VIII and XI)
As miosinas formam uma superfamília de proteínas de alto peso molecular com atividade mecanoquímica capaz de hidrolisar a molécula de ATP e de interagir com os filamentos de actina. A estrutura das miosinas pode ser divida de modo geral em cabeça motora, pescoço e cauda. São conhecidas 35 classes de miosinas em eucariotos sendo a classe II de miosinas

5. Ecologia de Florestas Atlânticas com ocorrência do muriqui (Brachyteles spp.): diversidade, sucessão secundária e estrutura nutricional / Atlantic Forests ecology holding muriqui (Brachyteles spp.): diversity, secondary succession and nutritional structure
This study has three chapters which mainly aimed the understanding on the role of forests variables affecting distribution, abundance and range ecology of primates belonging to Brachyteles genera. The first chapter specifically aimed on characterization and comparisons of tree species diversity and secondary succession among three forests holding Brachyteles

6. Estudos estruturais e dinamicos da proteina elicitora cerato-platanina / Structural and dynamics studies of the protein elicitor cerato-platanin
Um dos desafios que envolvem a patologia de plantas é determinar as bases moleculares que relacionam a patogenicidade do fungo na planta hospedeira. Em geral, o mecanismo pelo qual a planta se defende contra uma variedade de patógenos envolve o reconhecimento de moléculas específicas codificadas por esses microorganismos. A ceratoplatanina (CP) é uma pr

7. Proteomic inventory of myocardial proteins from patients with chronic Chagas' cardiomyopathy
Chronic Chagas' disease cardiomyopathy (CCC) is an often fatal outcome of Trypanosoma cruzi infection, with a poorer prognosis than other cardiomyopathies. CCC is refractory to heart failure treatments, and is the major indication of heart transplantation in Latin America. A diffuse myocarditis, plus intense myocardial hypertrophy, damage and fibrosis, in th

8. Viral membrane fusion: is glycoprotein G of rhabdoviruses a representative of a new class of viral fusion proteins?
Enveloped viruses always gain entry into the cytoplasm by fusion of their lipid envelope with a cell membrane. Some enveloped viruses fuse directly with the host cell plasma membrane after virus binding to the cell receptor. Other enveloped viruses enter the cells by the endocytic pathway, and fusion depends on the acidification of the endosomal compartment.

9. Aplicação de técnicas de aprendizado de máquina no reconhecimento de classes estruturais de proteínas
Atualmente, a classificação estrutural de proteínas, que diz respeito à inferência de padrões em sua conformação 3D, é um dos principais problemas em aberto da Biologia Molecular. Esse problema vem recebendo a atenção de muitos pesquisadores na área de Bioinformática pelo fato de as funções das proteínas estarem intrinsecamente relacionadas �

10. Purificação e caracterização estrutural de um inibidor de serinoprotease isolado de sementes de Cassia leptophylla. / Purification and structural caracter of serinoprotease of Cassia leptophylla seeds.
Inibidores de proteases - moléculas capazes de inibir a atividade catalítica de enzimas proteolíticas - compreendem uma das mais abundantes classes de proteínas em plantas. Nas sementes, as funções destas moléculas estão relacionadas com o controle de proteínas endógenas e com mecanismo de defesa contra insetos fitófagos. Este trabalho teve como o

11. New nuclear magnetic resonance methods for studying slow dynamics in organic solids: applications to polymers and proteins / Novas metodologias de ressonância magnética nuclear para o estudo da dinâmica lenta em materiais orgânicos no estado sólido: aplicações em polímeros e proteínas
Solid-State Exchange NMR is an important method to characterize details of dynamic process in materials science. However, the application of these techniques to study complex materials has been limited. In this work new solid-state Exchange NMR techniques, which allows efficient analysis of molecular motions in the millisecond time scale, are presented. The

12. Functional Organization of the Yeast SAGA Complex: Distinct Components Involved in Structural Integrity, Nucleosome Acetylation, and TATA-Binding Protein Interaction
SAGA, a recently described protein complex in Saccharomyces cerevisiae, is important for transcription in vivo and possesses histone acetylation function. Here we report both biochemical and genetic analyses of members of three classes of transcription regulatory factors contained within the SAGA complex. We demonstrate a correlation between the phenotypic s
