1. The Relationship between Contralateral Suppression of Transient Evoked Otoacoustic Emission and Unmasking of Speech Evoked Auditory Brainstem Response
Abstract Introduction Several studies have shown that efferent pathways of the auditory system improve perception of speech-in-noise. But, the majority of investigations assessing the role of efferent pathways on speech perception have used contralateral suppression of otoacoustic emissions as a measure of efferent activity. By studying the effect of effere

2. Role of nonproductive tillers as transient sinks of assimilates in wheat
ABSTRACT Although source–sink relationships in wheat are well studied, the performance of tillers as transient sinks is still unclear, especially under stress conditions. Thus, this work aimed to study the yield relationships of wheat stems in contrasting genotypes as affected by tiller treatment under stress conditions. Two experiments were conducted unde

3. Extracellular phospholipase production of oral Candida albicans isolates from smokers, diabetics, asthmatics, denture wearers and healthy individuals following brief exposure to polyene, echinocandin and azole antimycotics
Abstract Objective Candida albicans is the primary causative agent of oral candidosis, and one of its key virulent attributes is considered to be its ability to produce extracellular phospholipases that facilitate cellular invasion. Oral candidosis can be treated with polyenes, and azoles, and the more recently introduced echinocandins. However, once admini

4. The Study of Otoacoustic Emissions and the Suppression of Otoacoustic Emissions in Subjects with Tinnitus and Normal Hearing: An Insight to Tinnitus Etiology
Introduction Analysis of the suppression effect is a simple method to evaluate cochlear status and central auditory mechanisms and, more specifically, the medial olivocochlear system. This structure may be involved in the generation of mechanisms that cause tinnitus and in the pathophysiology of tinnitus in patients with tinnitus and n

5. Estudo do processamento auditivo e da supressão das emissões otoacústicas em crianças com dislexia do desenvolvimento / Study of auditory processing and suppression of otoacoustic emissions in children with developmental dyslexia
Introduction: For an adequate development of learning and writing abilities it is necessary the nervous system integrity, selective and sustained attention, auditory discrimination, short and long term memories and phonological awareness, which can be evaluated through auditory processing (AP) tests. It has been suggested that the function of the medial oliv

6. Crianças prematuras: estudo da supressão das emissões otoacústicas e da resolução temporal. / Premature children: study of suppression effect of otoacoustic emissions and temporal resolution
Objective: Determine the occurrence of the suppression of otoacoustic emissions, the temporal resolution hearing skill and the association between the results of these assessments and premature birth as well as the presence of signs suggestive of an alteration in auditory processing during development, in premature, below 2000g at birth. Methods: Forty low-i

7. Efeito de candidatos a supressores de silenciamento gênico viral em expressão de proteína recombinate em plantas
The aim of this work was to increase the efficiency of transient heterolog protein expression system using viral gene-silencing suppressors and Agrobacterium integrated. The use of plants as bioreactor is a promising strategy for large scale production of the heterolog protein. However, the use of genetically modified plants may lead to low protein expressio

8. Audiological, electroacoustic and electrophysiological hearing assessment of adults with HIV/AIDS / Avaliação audiológica, eletroacústica e eletrofisiológica da audição em adultos com HIV/AIDS
INTRODUCTION: The Acquired Immunodeficiency Syndrome is caused by the human immunodeficiency virus, a specific retrovirus that affects the immunological system allowing the emergence of several opportunistic infections, and that may also affect the central auditory nervous system. AIM: To assess the peripheral and central auditory pathways of the auditory sy

9. Controle automatico eletronico de ganho com supressão de transientes aplicado a EDFAs em redes opticas WDM / Eletronic automatic gain control with transient suppresion applied over WDM optical networks
IIn WDM optical communication systems erbium doped fiber amplifiers (EDFA) have an essential function, enabling amplification of simultaneous channels independently of transmit rate. The majority of current WDM systems use point to point configuration operating with a fixed number of channels over the optical link. However, the new generation optical systems

10. Gene expression analysis in sweet orange in response to Xanthomonas axonopodis pv. citri and Xanthomonas axonopodis pv. aurantifolii / Expressão diferencial de genes de laranja doce em resposta a infecção por Xanthomonas axonopodis pv. citri e axonopodis pv. aurantifolii
The most aggressive form of the citrus canker disease is caused by the bacteria Xanthomonas axonopodis pv. citri (Xac), which can infect all commercial varieties or species of citrus. In addition to Xac, Xanthomonas axonopodis pv. aurantifolii (Xaa) causes a weaker form of the disease, known as cancrose C, which is restricted to Mexican Lime (Citrus aurantif

12. Avaliação de individuos com queixa de zumbido por meio de procedimentos psicoacústicos e eletroacústicos
Introduction: In an attempt to understand some aspects related with tinnitus we formulated the hypothesis that there would be a dysfunction of the efferent auditory system, more precisely in the region of the superior medial olivocochlear system (SMOCS). In addition to Suppressíon of Otoacoustic Emissions by Transient Stimuli (SOAETS), Acoustic Reflex measu
