UNLABELLED The medial olivocochlear tract has efferent control over the outer hair cells, regulating the slow contractions and damping the fast ones. Using ipsilateral, contralateral or bilateral otoacoustic emissions amplitude studies, it is possible to estimate the conditions of this tract, since the effect resulting from the reduction/suppression of(More)
UNLABELLED An audiogram is not sufficient to indicate cochlear dead regions. AIM To investigate cochlear dead regions in sensorineural hearing loss subjects using the TEN test. SITE: CEDALVI/ HRAC-USP-Bauru/Sao Paulo/Brazil, August 2003 to February 2004. STUDY DESIGN A contemporary cross-sectional cohort study. MATERIAL AND METHODS The TEN test was(More)
BACKGROUND Heat shock proteins (Hsp) are major chaperone molecules that have recently emerged as cancer therapeutic targets owing to their involvement in tumor cell proliferation, differentiation, invasion and metastasis. High levels of extracellular Hsp90 and Hsp70 have been closely associated with a wide range of human cancers. Accumulating evidence(More)
A low-cost modular compact personal computer-based system for surface precordial mapping (SPM) developed by the authors was used to detect rejection periods, documented by endomyocardial biopsy (EB), in heart transplant patients on cyclosporine A therapy. Data were collected with a matrix of 35 Ag-AgCl electrodes positioned over the precordio with(More)
A computerized Data Acquisition System conceived and built by LNETI/DEE in cooperation with Department of Cardiology of Hospital Santa Cruz, and its application to processing and representation of cardiac precordial maps (MAPCARD SYSTEM), was described. A description was made about the evolution on cardiac maps, their main areas of interest, pointing to(More)
SUMMARY Introduction: The most frequent complaint of the cochlear implant users has been to recognize and understand the speech signal in the presence of noise. Researches have been developed on the speech perception of users of cochlear implant with focus on aspects such as the effect of the reduction to the signal/ noise ratio in the speech perception,(More)
UNLABELLED Hearing loss is one of the most common clinical findings in subjects with malformations of the ear. Treatment consists of surgery and/or adapt a hearing aid amplification by bone (HA VO). Early intervention is critical to auditory stimulation and development of speech and language. OBJECTIVE To characterize the audiological profile of subjects(More)
