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. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have

3. Morphology of immatures of Euschistus (Mitripus) grandis (Insecta: Hemiptera: Pentatomidae)
Immatures are important sources of information about characters, thus potentially improving classification and phylogenies. Euschistus (Mitripus) grandis Rolston, 1978 occurs in southern and southeastern Brazil. There are no references in the literature about this species other than the original description and distribution records. Our aim is to describe th

4. Mapping and signaling of neural pathways involved in the regulation of hydromineral homeostasis
Several forebrain and brainstem neurochemical circuitries interact with peripheral neural and humoral signals to collaboratively maintain both the volume and osmolality of extracellular fluids. Although much progress has been made over the past decades in the understanding of complex mechanisms underlying neuroendocrine control of hydromineral homeostasis, s

5. 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

6. Diabetic nephropathy
Diabetic nephropathy is the leading cause of chronic renal disease and a major cause of cardiovascular mortality. Diabetic nephropathy has been categorized into stages: microalbuminuria and macroalbuminuria. The cut-off values of micro- and macroalbuminuria are arbitrary and their values have been questioned. Subjects in the upper-normal range of albuminuria

7. Otoacoustic emission suppression and acoustic reflex sensitization in auditory processing disorders / Supressão das emissões otoacústicas e sensibilização do reflexo acústico no distúrbio de processamento auditivo
INTRODUCTION: Auditory processing depends on the auditory pathways integrity. Efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression. OBJECTIVE: Analyze efferent auditory system activity by otoacoustic emissions suppression and acoustic reflex sensitization in human

8. Transient otoacoustic emissions suppression in pre-term infants of high risk for hearing loss / Efeito de supressão das emissões otoacústicas evocadas por estímulo transiente em lactentes de risco nascidos pré-termo
Objective: The objective of this research was to study the occurrence and magnitude of the transient otoacoustic emissions suppression in pre-term infants of high risk for hearing loss. Methods: The was carried out in 15 preterm infants. The equipment used was the ILO USB II V6 Clinical OAE Software from Ododynamics. The stimulation used was linear click pre

9. Zumbido e audição normal: estudo do reflexo acústico e da supressão das emissões otoacústicas
Introduction: The functioning of the auditory pathway of patients with tinnitus complaints and normal hearing can be directly related to a mal-functional in the auditory efferent pathway, regarding the level of the olivocochlear superior system, in which, the acoustic reflex threshold data and the otoacustic emissions with contralateral noise may represent a

10. Influência da idade na atividade do trato olivococlear medial eferente sobre as propriedades mecânicas da cóclea em indivíduos ouvintes normais / Age influence in the activity of medial efferent olivocochlear tract upon mechanical properties of cochlea in normal hearing individuals
Medial olivocochlear tract makes the efferent control of the outer hair cells, controlling the slow contractions and mitigating rapid contractions. Upon the appearance of techniques for the investigation of the amplitude of otoacoustic emissions with and without acoustic stimulation against, ipsi and bilaterally, it is now possible to stimulate clinically th

11. Functional studies of the ataxin-3 protein / Estudos funcionais da proteina ataxina-3
Spinocerebellar ataxia type 3 (SCA 3) also known as Machado-Joseph disease (MJD) belongs to a heterogeneous group of neurodegenerative diseases of the central nervous system and is characterized by the degeneration of cerebellum and its afferent and efferent ways. The SCA3/MJD gene was mapped on chromosome 14 and was named MJD1, the causative mutation is an

12. Histological characterization of Sticholecitha serpentis Prudhoe, 1949 (digenea, bieriidae, sticholecithinae), parasite of Bothrops moojeni Hoge, 1966 (serpentes, viperidae)
The aim of this study was to evaluate the morphology of the species Sticholecitha serpentis Prudhoe, 1949 by means of histological procedures. Helminths were previously fixed in Railliet & Henry solution, uncompressed and were included in 2-hydroxyethyl-methacrylate. Longitudinal and transverse serial sections with a 4-mum thickness were performed in a micro
