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. The effectiveness of berberine on noise-induced hearing loss: a rat model
SUMMARY OBJECTIVE: Noise-induced hearing loss is a preventable form of hearing loss that has serious social and economic impacts. This study aimed to investigate the protective effect of berberine, a potent antioxidant and anti-inflammatory agent, against Noise-induced hearing loss. METHODS: After applying distortion product otoacoustic emission, 28 female

3. Reliability of Contralateral Suppression in Evoked Distortion Product Otoacoustic Emissions
Abstract Introduction Distortion product otoacoustic emissions (DPOAE) and their suppression may be considered useful in monitoring cochlear function and the efferent auditory pathway inhibitory effect. Nonetheless, the establishment of reliable parameters of response variations is of great importance. Objectives To verify the replicability of test and ret

4. Sound Generator: Analysis of the Effectiveness of Noise in the Habituation of Tinnitus
Abstract Introduction Tinnitus is a disorder that affects 10 to 15% of de world's population. Sound therapy performed through hearing aids (HAs) with integrated sound generator (SG) is one of the forms of tinnitus treatment. Objective To analyze the effectiveness of four masking noises in relieving tinnitus in individuals with mild and moderate bilateral s

7. Evaluation of selective attention in patients with misophonia
Resumo Introdução: A misofonia é caracterizada pela aversão a certos sons muito seletivos, que evocam uma forte reação emocional. Tem sido demonstrado que a misofonia, bem como o zumbido, está associada à hiperconectividade entre os sistemas auditivo e límbico. Indivíduos com zumbido incômodo podem ter comprometimento da atenção seletiva, mas i

8. Auditory Processing Assessment in Children with Attention Deficit Hyperactivity Disorder: An Open Study Examining Methylphenidate Effects
Abstract Introduction Children with Attention Deficit Hyperactivity Disorder can present Auditory Processing (AP) Disorder. Objective The study examined the AP in ADHD children compared with non-ADHD children, and before and after 3 and 6 months of methylphenidate (MPH) treatment in ADHD children. Methods Drug-naive children diagnosed with ADHD combine

9. Heart disease and the stress hypothesis in the mid-twentieth century: a historical review
Abstract Background In the 1920s, heart disease (a noncommunicable disease), was the new leading cause of death in the USA. Simultaneously, experimental progress in the study of stress provided scientific justification for a new type of risk factor. The objective of the present work is to examine the history of heart disease as a public health problem and

10. Parametric Study of Stay Cables of a Bridge Under Simulated Spatially Correlated Turbulent Wind
Abstract The main objective of this work is to carry out a parametric study of stay cables of a bridge under simulated spatially correlated buffeting forces. This vibration mechanism is simulated with an Autoregressive and Moving Average (ARMA) model, and applied to mathematical models of the stay cables of the tallest cable-stayed bridge in Mexico. The use

11. Performance Comparison of the IMMPDAF Algorithm Using Real and Simulated Radar Measurements
ABSTRACT Performance indexes obtained in idealized simulated scenarios are the primary source of data for evaluating different target tracking algorithms in most researches presented in the literature. Despite the convenience of simulation, ultimate evaluation of a tracking algorithm must be made in real scenarios. Unfortunately, real radar measurements as w

12. The Effect of Material Property on the Critical Velocity of Randomly Excited Nonlinear Axially Travelling Functionally Graded Plates
Abstract In this paper, the critical axial speeds of three types of sigmoid, power law and exponential law functionally graded plates for both isotropic and orthotropic cases are obtained via a completely analytic method. The plates are subjected to lateral white noise excitation and show evidence of large deformations. Due to randomness, the conventional de
