1. Transferência de funções ordinais através de classes de estímulos equivalentes em surdos / Transfer of ordinal functions through stimulus classes in hearing impaired individuals
The bilingual approach, adopted for educating deaf people in Brazil, regards the Brazilian Sign Language (Libras) as the first language and the written Portuguese Language as the instrumental language. The acquisition of the written language may be more difficult than the acquisition of the sign language due to the differences between their ordinal grammatic

2. Programa Bolsa Família e o empoderamento das mulheres em Minas Gerais / Programa Bolsa Família and the empowerment of the women in Minas Gerais
Under the gender perspective the empowerment emerged as an important theme in the public policy field. So, this study was carried out to analyze the empowerment dimensions reached by the women benefiting from the Income Transfer Program so-called Bolsa Família and under the social agents perception in the Social Assistance Reference Centers (CRAS) and the i

3. Discriminações simples simultâneas e sucessivas - na formação de classes funcionais / Simple simultaneous and successive discriminations and the emergence of functional classes
Functional classes can be established thorough simple discrimination and repeated reversals training. However, successive reversals necessarily involve experience with the occurrence of errors, which may interfere with class formation. A previous study using this procedure indeed generated a pattern of errors that seemed to be related to the position of the

4. Transferência de funções ordinais através de classes de estímulos equivalentes: contribuições para a programação de ensino de adultos e crianças surdas e de crianças ouvintes
Currently, in Brazil, education for deaf people prioritizes the bilingual approach, in which the Brazilian Sign Language (LIBRAS) is taught as the first language, and the written Portuguese Language is taught as the instrumental language. The acquisition of the written Portuguese Language can be difficult for deaf people due to the differences between the or

5. Investigação de propriedades quantitativas de relações simbólicas em quatro estudos experimentais envolvendo o paradigma de equivalência de estímulos
This work presents four experimental studies that evaluated transfer of functions from faces expressing emotions to arbitrary figures equivalent to them. The specific goals of each study can be articulated around a proposal to investigate quantitative properties of equivalence relations. Chapter 1 describes an experiment conducted to examine if the level of

6. A participação de respostas de autodiscriminação em classes de estímulos equivalentes / Self-discriminated responses as members of equivalence stimulus classes
The purpose of this study was: (1) to establish the control of two (typing) responses as SD or conditional stimuli over a second response of choice between stimuli in a MTS task, (2) to verify if the typing responses became members of equivalent stimulus classes, and (3) if other stimuli of the equivalent classes would have discriminative functions similar t

7. Efeito da inibição da fosfodiesterase-5 sobre as propriedades de transdução dinâmica do nervo vago cardíaco em ratos espontaneamente hipertensos.
Recent data have reported that sildenafil citrate, an inhibitor of phosphodiesterase-5 (PDE-5), widely used in the treatment of erectile dysfunction, causes vasodilation and reflex sympathetic activation, which may enhance cardiovascular risk. However, the effects of sildenafil citrate on cardiac vagal parasympathetic control, in the arterial hypertension co

8. Sinalização celular durante aumento de tensão no coração : implicações no desenvolvimento de hipertrofia cardiaca : estudos em corações isolados
The mechanical input plays a major role in cardiac adaptive responses to hemodynamic overload. In addition of triggering the force-Iength mechanism and the homeometric autoregulation, the mechanical input activates signaling mechanisms involved on hypertrophic growth of cardiac myocytes, the hal1mark of themyocardial structural adaptation in response to sust

9. Single photon signals in fly photoreceptors and first order interneurones at behavioral threshold.
1. The contrast sensitivity of the optomotor response of the fly Musca domestica was measured using a moving sinusoidal grating as the stimulus. In parallel experiments intracellular recordings were made from photoreceptors and first order visual interneurones to to determine their responses to the same threshold stimuli. Measurements of the spatial modulati

10. Suppression of deregulated c-MYC expression in human colon carcinoma cells by chromosome 5 transfer.
Two-thirds of sporadic colon carcinomas express elevated levels of the c-MYC protooncogene. In addition, most colon carcinoma cell lines show constitutive elevated expression (10- to 40-fold over normal) of MYC RNA and protein that is not modulated in response to a mitogenic stimulus. Indirect immunofluorescence has been used to detect c-MYC protein in such

11. Two cytosolic components of the human neutrophil respiratory burst oxidase translocate to the plasma membrane during cell activation.
The superoxide-forming respiratory burst oxidase of human neutrophils is composed of membrane-associated catalytic components and cytosolic constituents required for oxidase activation. This study concerns the hypothesis that cytosolic oxidase components translocate to a membrane fraction when neutrophils are stimulated and the oxidase is activated. A polycl

12. Binding of sequence-specific proteins to the adenosine- plus uridine-rich sequences of the murine granulocyte/macrophage colony-stimulating factor mRNA.
Adenosine+uridine (AU)-rich sequences in the 3' untranslated region (3'UTR) of the mRNA of many cytokines and oncogenes play an important role in mediating RNA degradation. Among the cytokines containing such AU-rich sequences in their 3'UTR is the hematopoietic growth factor granulocyte/macrophage colony-stimulating factor (GM-CSF). GM-CSF gene expression i
