Abstract:

Quantitative studies of the vestibular system with serially sectioned human temporal bones have been limited because of difficulty in distinguishing hair cells from supporting cells and type I from type II hair cells. In addition, there is only a limited amount of normative data available regarding vestibular hair cell counts in humans. In this study, archival temporal bone sections were examined by Nomarski (differential interference contrast) microscopy, which permitted visualization of the cuticular plate and stereociliary bundle so as to allow unambiguous identification of hair cells.

Twenty-three human temporal bones were dissected to study the anatomy of the round window with respect to cochlear implantation. Information was also gathered concerning the passage of a 22-channel electrode array along the cochlear duct by using cochlear surface dissection preparations. The insertion length and any insertion trauma were noted both by observation at the time of insertion and by careful analysis of video recordings. The crista semilunaris did not interfere with smooth electrode insertion. The recommendation is made that enlarging the round window anteroinferiorly is unnecessary

With the use of immunolabeling, we identified the SAN as a neurofilament 160-positive but connexin 43-negative region ( n = 5). Normal excitation originated in the SAN center with a cycle length (CL) of 405 ± 14 ms ( n = 14), spread anisotropically along the crista terminalis (CT), and f

Furthermore, some TBs from patients with BPPV do not contain particles in the posterior canal. Five TBs from patients with BPPV were studied quantitatively and qualitatively.

Both symptomatic and occult nonoperated ILS were included for further analysis. <b><i>Results:</i></b> A total of 6 ILS were identified, with 4 intracochlear and 2 intravestibular schwannomas. All intracochlear schwannomas involved th

Abstract:

A partir da experiência etnográfica no contexto urbano da cidade de Porto Alegre, RS, propõe-se refletir a dinâmica espaço-temporal da memória do trabalho apoiando-se em narrativas biográficas de ex-trabalhadores de um antigo Estaleiro. Com base no estudo das redes de trabalho vinculadas à territorialidade da região da Orla do rio Guaíba, próximo ao Cristal, em Porto Alegre, RS, propõe-se investigar a rítmica e ressonâncias do fluxo das transformações urbanas nas suas relações com práticas de trabalho operário. Trata-se de pensar as continuidades e descontinuidades do tempo vivido de uma exper

Abstract:

O presente trabalho teve como objetivo principal a comparação da estrutura da comunidade bentônica e cobertura coralínea entre 2010 (ano de potencial branqueamento) e 2013 nos recifes de corais de Maragogi. A pesquisa de campo foi realizada nas cristas recifais por duas metodologias do Protocolo Reef Check, que foram: point intercept transect (PIT) e foto quadrats (FOT). As anomalias de temperatura superficial no mar na área não foram suficientes para causar branqueamento nos corais dos sítios estudados em 2010. Ambos os métodos revelaram que a cobertura total de corais se manteve estável nos

Abstract:

The assessment of habitat selection and temporal patterns of activity rhythms is paramount for wildlife conservation. Studies on behavioural ecology of wild mammals are particularly challenging in tropical areas, mostly when involving rare or elusive species. Despite being a common species in Italy, the crested porcupine Hystrix cristata is threatened of extinction throughout most of its sub-Saharan range. All available information on the ecology of this species has been collected in Italy, whereas no data is present in the scientific literature on spatiotemporal behaviour of this large rodent

Abstract:

Abstract Background Atrial Fibrillation (AF) is the most common atrial arrhythmia. The initiation and perpetuation of AF are related to atrial remodeling affecting the electrical and structural atrial characteristics. The beat-to-beat analysis of the P-wave morphology (PWM), during sinus rhythm (SR), revealed the existence of a secondary PWM, while the proportion of the P-waves which follow the secondary morphology is higher in patients with a history of paroxysmal AF (pAF). This observation has led to the hypothesis that the multiple PWM may be the result of a transient shift in the stimulus
