13. Expressão local de interferon alfa, dos receptores de interferon alfa (IFNAR) e da enzima 25Oligoadenilato sintetase em pacientes com neoplasia intraepitelial cervical
Interferor-alfa (IFN-α) is a glicoprotein belonged to a family of cytokines which participate in the control and cell replication in the defence of hostess against strange organisms, as vírus or bacteria. Although the IFN-α has been known by antiviral property, numerous investigations afterward showed that the IFN is involved on regulation cell gr

14. Study of charge and mass transference on copper/liquid interface : an application of QCM / Estudo da transferencia de carga e massa na inteface cobre/liquido : uma aplicação da QCM
In this work we used the QCM (Quartz Crystal Microbalance) as an alternative technique for the studying of the corrosion/inhibition of cooper. We studied the protection of cooper surfaces due to the adsorption of a volatile corrosion inhibitor, (VCI-Cyclehexilamine-Benzoate). We used electrochemical techniques to characterize the corrosion in different envir

15. Simultaneous overexpression of GH and STAT5b genes inhibits the STAT5 signalling pathway in tilapia (Oreochromis niloticus) embryos
In this study, we describe the use of a STAT5 responsive element (LHRE) reporter gene to monitor the activity of the growth hormone (GH) transduction pathway following expression of heterologous fish GH and rat STAT5b in tilapia embryos and fish fibroblast cells. Our results indicate that both GH and STAT5b are able to activate the LHRE at high levels when t

16. Influencia dos aditivos na obtenção de mamão desidratado osmoticamente
A growing interest has been manifested in relation to some fruits and vegetables submitted to soft processing, assuring a sensorial quality closer to the fresh food, as well as a greater resistance to degradation. The osmotic dehydration is a process that provides a good sensorial quality [mal product due to the use of low temperatures and also allows a simu

17. Specific Inhibition of Phototropism in Corn Seedlings 1
Geotropism was used as a control for the specificity of potential inhibitors of phototropism by the coleoptiles of corn (Zea mays) seedlings. The compounds tested fall into three categories showing: (a) no inhibition of either phototropism or geotropism (KCl); (b) nonspecific inhibition of both phototropism and geotropism (KCN); and (c) specific inhibition o

18. Transformation by v-Src: Ras-MAPK and PI3K-mTOR Mediate Parallel Pathways
An increase in the level of active, GTP-bound Ras is not necessary for transformation of chicken embryo fibroblasts (CEF) by v-Src. This suggests that other Ras-independent pathways contribute to transformation by v-Src. To address the possibility that activation of phosphatidylinositol-3-kinase (PI3K) and the mammalian target of rapamycin (mTOR/FRAP), repre

19. Bacteriophage T4 Inhibits Colicin E2-Induced Degradation of Escherichia coli Deoxyribonucleic Acid I. Protein Synthesis-Dependent Inhibition1
The deoxyribonucleic acid (DNA) of Escherichia coli B is converted by colicin E2 to products soluble in cold trichloroacetic acid; we show that this DNA degradation (hereafter termed solubilization) is subject to inhibition by infection with bacteriophage T4. At least two modes of inhibition may be differentiated on the basis of their sensitivity to chloramp

20. Mutually exclusive inhibition of herpesvirus DNA polymerase by aphidicolin, phosphonoformate, and acyclic nucleoside triphosphates.
Dual inhibitor studies were performed to examine the interaction of aphidicolin, phosphonoformate, 9-(2-hydroxyethoxymethyl)guanine triphosphate, and 9-(1,3-dihydroxy-2-propoxymethyl)guanine triphosphate with herpes simplex virus DNA polymerase. Kinetic data indicated that inhibition by one agent prevents simultaneous inhibition by a second agent, producing

21. Quantitation of dengue precipitating antibody by inhibition countercurrent immunoelectrophoresis.
The inhibition countercurrent immunoelectrophoresis test was employed to detect dengue virus antibody in patients' sera. Anti-dengue type 2 titers determined by inhibition countercurrent immunoelectrophoresis correlated well with hemagglutination inhibition titers. In secondary cases, more than fourfold increases in precipitating antibodies were observed. Th

22. Bacteriocin-mediated inhibition of Clostridium botulinum spores by lactic acid bacteria at refrigeration and abuse temperatures.
The bacteriocinogenicity of Lactococcus lactis ATCC 11454, Pediococcus pentosaceus ATCC 43200, P. pentosaceus ATCC 43201, Lactobacillus plantarum BN, L. plantarum LB592, L. plantarum LB75, and Lactobacillus acidophilus N2 against Clostridium botulinum spores at 4, 10, 15, and 35 degrees C was investigated by modified deferred and simultaneous antagonism meth

23. Pattern and inhibition-dependent invasion of pyramidal cell dendrites by fast spikes in the hippocampus in vivo.
The invasion of sodium spikes from the soma into dendrites was studied in hippocampal pyramidal cells by simultaneous extracellular and intracellular recordings in anesthetized rats and by simultaneous extracellular recordings of the somatic and dendritic potentials in freely behaving animals. During complex-spike patterns, recorded in the immobile or sleepi

24. A gamma-aminobutyric-acid-mediated inhibition of neurones in the nucleus tractus solitarius of the cat.
1. Extracellular recordings were made from 123 synaptically activated neurones in the nucleus tractus solitarius of the chloralose-anaesthetized cat. 2. Ninety-one neurones were activated by electrical stimulation of cardiac or pulmonary vagal branches and thirty-two by stimulation of the aortic nerve. 3. Ionophoretic application of GABA abolished or markedl
