1. Changes in hepatic metabolic enzyme activities and biliary excretion of 4-nitrophenol in streptozotocin induced diabetic rats
Abstract Activity of hepatic metabolic enzymes of glucuronidation and sulfation of 4-nitrophenol (PNP) and biliary excretion of its glucuronide (PNP-G) and sulfate (PNP-S) conjugates have been investigated in control and streptozotocin (STZ)-induced diabetic rats. 500 μM PNP solution was luminally perfused in a cannulated jejunal loop for 90 minutes. It was

2. Isolation and characterization of a promoter responsive to salt, osmotic and dehydration stresses in soybean
Abstract Drought stress is the main limiting factor of soybean yield. Currently, genetic engineering has been one important tool in the development of drought-tolerant cultivars. A widely used strategy is the fusion of genes that confer tolerance under the control of the CaMV35S constitutive promoter; however, stress-responsive promoters would constitute the

3. Metabolic profile and β-glucuronidase inhibitory property of three species of Swertia
ABSTRACT β-Glucuronidase inhibitors are suggested as potential hepatoprotective agents. Swertia chirayita (Roxb.) Buch.-Ham. ex C.B. Clarke, Gentianaceae, is known for its hepatoprotective and anti-hepatotoxic activity in Ayurvedic system of medicine for ages. This plant is substituted by other species like S. decussata Nimmo ex C.B. Clarke and S. bimaculat

4. Relationship among Shigella spp. and enteroinvasive Escherichia coli (EIEC) and their differentiation
Shigellosis produces inflammatory reactions and ulceration on the intestinal epithelium followed by bloody or mucoid diarrhea. It is caused by enteroinvasive E. coli (EIEC) as well as any species of the genus Shigella, namely, S. dysenteriae, S. flexneri, S. boydii, and S. sonnei. This current species designation of Shigella does not specify genetic similari

5. Optimization of particle bombardment parameters for the genetic transformation of Brazilian maize inbred lines.
The objective of this work was to develop a genetic transformation system for tropical maize genotypes via particle bombardment of immature zygotic embryos. Particle bombardment was carried out using a genetic construct with bar and uidA genes under control of CaMV35S promoter. The best conditions to transform maize tropical inbred lines L3 and L1345 were ob

6. Importância da região amino-terminal da proteína RolA de Agrobacterium rhizogenes em sua atividade biológica.
A proteina RolA e originaria de Agrobacterium rhizogenes, uma bacteria fitopatogenica que provoca a doenca conhecida como raiz em cabeleira (?ghairy root?h). RolA atua no processo de infeccao, sendo codificada no T-DNA do plasmideo Ri da agrobacteria. Embora a expressao de RolA em plantas implique em severas alteracoes morfologicas e fisiologicas, seu mecani

7. Otimização dos parâmetros de bombardeamento de partículas para a transformação genética de linhagens brasileiras de milho
O objetivo deste trabalho foi desenvolver um sistema de transformação genética para genótipos tropicais de milho pelo bombardeamento de embriões imaturos com micropartículas. O bombardeamento com partículas foi realizado utilizando-se uma construção gênica contendo os genes bar e uidA sob o controle do promotor CaMV35S. As melhores condições para

8. Co-transformation of a tropical maize endophytic isolate of Fusarium verticillioides (synonym F. moniliforme) with gusA and nia genes
A tropical endophytic isolate of the fungus Fusarium verticillioides (synonym Fusarium moniliforme) obtained from Zea mays was co-transformed with plasmid pNH24 containing the Fusarium oxysporum nitrate reductase nia gene and plasmid pNOM 102 carrying the Escherichia coli b-glucuronidase gusA gene. Transformation frequency for the nia marker was 75 transform

9. Agrobacterium-mediated transformation of sorghum: factors that affect transformation efficiency
The results presented in this work support the hypothesis that Agrobacterium-mediated transformation of sorghum is feasible, analogous to what has been demonstrated for other cereals such as rice, maize, barley and wheat. The four factors that we found most influenced transformation were: the sensitivity of immature sorghum embryos to Agrobacterium infection

10. Expressão transiente do gene gus, sob regulação de quatro promotores, em diferentes tecidos de mamoeiro (Carica papaya L.) e videira (Vitis sp.)
O mamoeiro (Carica papaya L.) e a videira (Vitis vinifera L.) destacam-se entre as fruteiras produzidas no Brasil por serem plantadas em quase todo o território nacional e apresentarem importância econômica e social. A tecnologia de produção de organismos geneticamente modificados, também conhecidos como "transgênicos", tem grande potencial de uso no

12. Evaluation of parameters which affect the agrobacterium mediated genetic transformation of eucalyptus grandis. / Avaliação de parâmetros que influenciam a transformação genética do Eucalyptus grandis via Agrobacterium.
The research project aimed the establishment of a method for genetic transformation of Eucalyptus grandis; an important and widely planted forestry tree in Brazil. Two techniques of transformation were tested: agrobiolistic of explants with accumulation of meristematic cells and SAAT ( sonication-assisted Agrobacterium mediated transformation ). Both systems
