1. Sequências, propriedades e função de β-1,3-glucanases de insetos / Sequences, properties and function of insect β-1,3-glucanases
β-1,3-glucanases são enzimas encontradas em muitos organismos, como fungos, bactéria e plantas. Suas funções incluem remodelamento de parede celular, defesa e digestão. É um alvo interessante para o controle populacional de insetos-praga, porque é ausente em vertebrados. Em insetos, é encontrada no intestino de muitas ordens diferentes, e hidrol

2. Identification of distinct evolutionary units in allopatric populations of Hypostomus cf. wuchereri Günther, 1864 (Siluriformes: Loricariidae): karyotypic evidence
Few chromosomal reports are available for the endemic fish fauna from coastal basins in northeastern Brazil, and regional biodiversity remains partially or completely unknown. This is particularly true for Loricariidae, the most diverse family of armored catfishes. In the present work, allopatric populations of Hypostomus cf. wuchereri (Siluriformes: Loricar

3. AnÃlise da antigenicidade e expressÃo de quatro novas proteÃnas hipotÃticas de Leishmania.(Leishmania) Chagasi
Leishmaniasis are parasitary infectious-diseases endemic in many countries caused by protozoan parasites of the genus Leishmania. Current strategies to combat visceral leishmaniasis, the most lethal and often fatal form of the disease unless treated, have not so far been successful. For this reason identification of recombinant antigens that can be used in d

4. Purification and characterization of a carboxypeptidase and a dipeptidase from Tenebrio molitor (Coleoptera) larvae / Purificação e caracterização de uma carboxipeptidase e de uma dipeptidase da larva de Tenebrio molitor (Coleoptera)
Devido aos problemas, ambientais e à população humana, causados pelos inseticidas químicos, novas investigações para o controle de insetos tornaram-se necessárias. Para isto, um maior conhecimento sobre a fisiologia digestiva dos insetos torna-se essencial, visto que o intestino é uma interface, grande e relativamente desprotegida, entre o inseto e o

5. α-Mannosidases intestinal from Tenebrio molitor (Coleoptera) larvae / α-Manosidases intestinais da larva de Tenebrio molitor (Coleoptera)
Studies of intestinal function were prompted after noticing that the gut is a huge and relatively unprotected interface between the insect and the environment and can thus be used as a target for pest control. In this context, our work involves the purification and characterization of an soluble alpha-mannosidase and detection of a membrane α-mannosidas

6. Experimental approaches to study the nutritional value of food ingredients for dogs and cats
This review covers methods that have been applied to study the nutrient value or quality of specific ingredients fed to dogs, cats and comparable species (i.e. foxes, minks, rats, etc.). Typically, the nutritional value or utilization of a specific ingredient is measured by total tract digestibility and has been expanded through the measurement of total nutr

7. Identification of the divergent calmodulin binding motif in yeast Ssb1/Hsp75 protein and in other HSP70 family members
Yeast soluble proteins were fractionated by calmodulin-agarose affinity chromatography and the Ca2+/calmodulin-binding proteins were analyzed by SDS-PAGE. One prominent protein of 66 kDa was excised from the gel, digested with trypsin and the masses of the resultant fragments were determined by MALDI/MS. Twenty-one of 38 monoisotopic peptide masses obtained

8. Investigation of a novel Bacillus thuringiensis toxin
The aim of the present work was to investigate the toxicity, biochemical characteristics, gene and protein contents, and the mechanism of action of toxins from the Brazilian Bacillus thuringiensis (Bt) strain S725. This strain has been reported as toxic against the cotton boll weevil (Anthonomus grandis), a severe pest of cotton crops in America, which is co

9. Densidade e área do perfil celular dos neurônios mioentéricos reativos a acetilcolinesterase, NADH e NADPH-diaforase positivos do ceco de ratos (Rattus norvergicus) adultos / Density and area of the cellular outline of the myoenteric plexus reactive to Acethylcholinesterase, NADH and NADPH diaphorase positives of the caecum of adult (Rattus norvergicus) rats
Beginning in the terminal ileum where the ileal papilla opens, the caecum is the initial portion of the large intestine, where part of the digestion of the cellulose coming from the food and the absorption of its products take place. This study had the purpose of evaluating the density and the cell profile area of the myoenteric neurons in different regions

10. Identification of Human T-lymphotropic Virus Type I (HTLV-I) Subtypes Using Restrited Fragment Length Polymorphism in a Cohort of Asymptomatic Carriers and Patients with HTLV-I-associated Myelopathy/tropical Spastic Paraparesis from São Paulo, Brazil
Although human T-lymphotropic virus type I (HTLV-I) exhibits high genetic stability, as compared to other RNA viruses and particularly to human immunodeficiency virus (HIV), genotypic subtypes of this human retrovirus have been characterized in isolates from diverse geographical areas. These are currently believed not to be associated with different pathogen

11. In situ hybridization of bat chromosomes with human (TTAGGG)n probe, after previous digestion with Alu I
The purpose of this work was to verify the ability of the enzyme Alu I to cleave and/or remove satellite DNA sequences from heterochromatic regions in chromosomes of bats, by identifying the occurrence of modifications in the pattern of fluorescence in situ hybridization with telomeric DNA. The localization and fluorescence intensity of the telomeric DNA sit

12. Analysis of the intercellular fluid proteome of Xylella fastidiosa - infected citrus leaves. / Análise do proteoma do fluído intercelular de folhas de laranjeiras infectadas com Xylella fastidiosa.
In order to understand the mechanisms regulating the Xylella fastidiosacitrus (Citrus sinensis var. Pêra) interaction, proteins with differential accumulation in the apoplast of Xf-infected citrus leaves with or without disease symptoms as compared to non-infected leaves, were identified and characterized using 2D-PAGE and mass spectrometry (MALDI-ToF). The
