1. Correlação entre as contagens de reticulócitos manual e automática em amostras de felinos anêmicos
RESUMO O objetivo do presente estudo foi correlacionar os valores de reticulócitos pontilhados e agregados obtidos por metodologia manual com a metodologia automática de contagem de reticulócitos totais em amostras de sangue de gatos anêmicos, analisados em um contador hematológico com citometria de fluxo. Para isso, 40 amostras de sangue de pacientes f

2. Solubility as a limiting factor for expression of hepatitis A virus proteins in insect cell-baculovirus system
The use of recombinant proteins may represent an alternative model to inactivated vaccines against hepatitis A virus (HAV). The present study aimed to express the VP1 protein of HAV in baculovirus expression vector system (BEVS). The VP1 was expressed intracellularly with molecular mass of 35 kDa. The VP1 was detected both in the soluble fraction and in the

3. Detection and cellular localization of Xanthomonas campestris pv. viticola in seeds of commercial 'Red Globe' grapes
Commercial grapevine fruit (Vitis vinifera) of the Red Globe variety were collected in vineyards from Vale do São Francisco lower basin, an area of occurrence of grapevine bacterial canker. Seeds were extracted, classified as symptomatic or asymptomatic and processed in order to be observed under light (LM) and scanning electron microscopy (SEM) along with

4. Histomorphological changes by epididymal lithiasis in roosters
Epididymal lithiasis (EL) histopathology is described using light and electronic microscopy in roosters (Gallus gallus domesticus) naturally affected by EL in Minas Gerais, Brazil. The histologic and morphological changes by EL in roosters was performed regarding cellular and subcellular details through light and electron microscopy. Efferent ductules epithe

5. Obtenção e caracterização de frações purificadas de saponinas de chenopodium quinoa e avaliação da formação de complexos do tipo iscom : atividades biológicas das frações e dos complexos formados
Chenopodium quinoa (quinoa) seeds are a rich protein source and well-known for their high saponin content. Chemically, quinoa saponins are triterpene glycosides being phytolaccagenic, hederagenin, oleanolic and serjanic acids the most common aglycones found in seeds. Its immunoadjuvant properties have been examined and the results obtained were conflicting.

6. Iron-limited condition modulates biofilm and adhesive porpoerties in enteroaggregative Escherichia coli / Influência da limitação de ferro nas propriedades adesivas e na formação de biofilme de Escherichia coli enteroagregativa (EAEC)
Escherichia coli enteroaggregative (EAEC) can cause persistent or acute diarrhea. It is characterized by the aggregative adherence pattern on HEp-2 cells, with the presence of bacteria aggregates like stacked bricks. Many strains have the capacity to produce siderophores, low-molecular-mass compounds that capture iron under conditions of low concentration of

7. Modificação de linhagens industriais de Saccharomyces cerevisiae para o aumento da produtividade de alcool e floculação condicional / Genetic modification of industrial Saccharomyces cerevisiae strain to improve ethanol production and conditional flocculation
The increased need for replacing energy sources from fossil oil to renewable sources has prompted research initiatives throughout the world. Bioethanol is a highly competitive candidate to replace fuels such as gasoline. The production of Brazilian ethanol occurs by the fermentation of sugars from sugar cane juice by the yeast Saccharomyces cerevisiae. The i

8. Estudos estruturais do domínio GTPase isolado da septina humana SEPT4 e estrutura cristalográfica da Glutationa -S- Transferase de Xylella fastidiosa / Structural Studies of the GTPase domain from human SEPT4 and Crystallography Structure of Glutathione S-transferase from Xylella fastidiosa
The septins are a conserved family of guanine nucleotides-binding and hetero-filament forming. proteins. In mammals they are involved in a variety of cellular processes, such as cytokinesis, exocytosis, and vesicle trafficking. SEPT4 has been reported to accumulate in tau-based filamentous deposits and cytoplasmic inclusions in Alzheimers and Parkinsons dise

9. Estudo das alterações da membrana celular de microrganismos por compostos de inclusão de clorexidina: beta-ciclodextrina em diferentes proporções molares usando Microscopia de Força Atômica e Microscopia Eletrônica de Varredura
The formation of inclusion compounds of chlorhexidine for the controlled release of antimicrobials has shown decreasing in therapeutic concentrations effective. However, a lack of studies has been published about the mechanism which was inclusion compounds increase cellular permeability through the microorganisms membrane. Thus the objective of this work was

10. A micro-spreading improvement for spermatogenic chromosomes from Triatominae (Hemiptera-Reduviidae)
Cytogenetics of triatomines have been a valuable biological tool for the study of evolution, taxonomy, and epidemiology of these vectors of Trypanosoma cruzi. Here we present a single microtube protocol that combines micro-centrifugation and micro-spreading, allowing high quality cytogenetic preparations from male gonadal material of Rhodnius prolixus and Tr

11. Um algoritmo de alto desempenho para evoluir o modelo de Potts Celular
A simulação de sistemas celulares tem recebido grande interesse nos últimos anos. Em particular, o modelo de Potts celular é o mais utilizado na área dada a sua precisão em representar estes sistemas. Este modelo, na sua forma convencional, possui uma série de operações e cálculos que são executados de maneira pouco eficiente, o que impossibilita

12. Efeito da cisplatina em cultura de linhagens estabelecidas e sua capacidade de induzir transformação celular in vitro / Effesct of cisplatin on culture cell lines and its ability to induce cellular transformation in vitro
Cisplatin is an antineoplastic agent used to treat solid malignancies, such as testicular, ovarian and bladder tumors. However, both in vitro and in vivo, cisplatin has been shown to be mutagenic, genotoxic and tumorigenic. Maintained in culture, Vero cells presented behavioral and morphological alterations associated with cellular transformation in vitro, a
