Echolocating Whales and Bats Express the Motor Protein Prestin in the Inner Ear: A Potential Marker for Hearing Loss.
2020
Prestin is an integral membrane motor protein located in outer hair cells of the mammalian cochlea. It is responsible for electromotility and required for cochlear amplification. Although prestin works in a cycle-by-cycle mode up to frequencies of at least 79 kHz, it is not known whether or not prestin is required for the extreme high frequencies used by echolocating species. Cetaceans are known to possess a prestin coding gene. However, the expression and distribution pattern of the protein in the cetacean cochlea has not been determined, and the contribution of prestin to echolocation has not yet been resolved. Here we report the expression of the protein prestin in five species of echolo…
Task-oriented reading efficiency : interplay of general cognitive ability, task demands, strategies and reading fluency
2022
AbstractThe associations among readers’ cognitive skills (general cognitive ability, reading skills, and attentional functioning), task demands (easy versus difficult questions), and process measures (total fixation time on relevant and irrelevant paragraphs) was investigated to explain task-oriented reading accuracy and efficiency (number of scores in a given time unit). Structural equation modeling was applied to a large dataset collected with sixth-grade students, which included samples of dysfluent readers and those with attention difficulties. The results are in line with previous findings regarding the dominant role of general cognitive ability in the accuracy of task-oriented reading…
The precursors of double dissociation between reading and spelling in a transparent orthography.
2016
Research and clinical practitioners have mixed views whether reading and spelling difficulties should be combined or seen as separate. This study examined the following: (a) if double dissociation between reading and spelling can be identified in a transparent orthography (Finnish) and (b) the cognitive and noncognitive precursors of this phenomenon. Finnish-speaking children (n = 1963) were assessed on reading fluency and spelling in grades 1, 2, 3, and 4. Dissociation groups in reading and spelling were formed based on stable difficulties in grades 1–4. The groups were compared in kindergarten phonological awareness, rapid automatized naming, letter knowledge, home literacy environment, a…
Voz cantada y Electromiografía de Superficie: Un estudio comparativo de la actividad muscular en cantantes formados y no formados
2018
En los últimos años ha habido un incremento del uso de la Electromiografía de Superficie en logopedia, lo que se evidencia en el número creciente de publicaciones en este área en revistas científicas. Este instrumento permite presentar de forma objetiva y precisa la actividad mioeléctrica en tiempo real, es no invasiva y se percibe de fácil aplicación. El objetivo de este trabajo es comparar la actividad mioeléctrica de los músculos maseteros, suprahioideos y esternoicleidomastoideos de cantantes con y sin entrenamiento vocal reglado a través de la Electromiografía de Superficie durante la realización de un fonetograma. La muestra estuvo conformada por 12 sopranos con edades entre 19 y 29 a…
Unilateral sensorineural hearing loss in scholastic age subjects: Psychopedagogical aspects
2006
The Authors want to assess a probable significant relation between the unilateral sensorineural hearing loss and some learning difficulties and language acquisitions, often found, through our observation, in impaired children. The Authors have examined a group of subjects in their scholastic age who have this kind of hearing loss and, through several dialogues with them, they have gathered some relevant data about the difficulties that children have at school, and drawn up a questionnaire.
Jurisdiction in cases of divorce, legal separation or marriage annulment
2021
The subject of coordination is fundamental for the functioning of jurisdictional rules of the Regulation n.2016/1103 on matrimonial property regimes and Regulation n.2016/1104 on the property consequences of registered partnerships. Both Property Regimes Regulations have the purpose of gathering litigation before the courts of one Member State and have the related procedures managed by the courts of the same Member State. Recital 34 of Regulation No. 2016/1103 specifies that matters of matrimonial property regime related to proceedings pending before the court of a member state hearing an application for divorce, legal separation or marriage annulment should be dealt with by the courts of t…
General and special education teachers’ knowledge about reading comprehension processes and instructional practices
2022
AbstractThe study investigated teachers’ knowledge of reading comprehension processes and reading comprehension instruction. The study was carried out among teachers (N = 65) in Estonia. The content analysis classified qualitative data from semi-structured interviews as quantitative data. The results showed that teachers’ content knowledge about reading comprehension processes and pedagogical knowledge of reading comprehension instruction were considerably variable yet mostly limited. Special education teachers (n = 37) mentioned a wider range of reading strategies than classroom teachers (n = 28). When describing how to support struggling readers, significant differences emerged between th…
Verbesserte Auswertbarkeit transitorisch evozierter otoakustischer Emissionen durch Korrelationsfilterung
1993
Hearing screening as well as evaluation of cochlear function under therapy with ototoxic agents or patients with various diseases is increasingly done by registration of transient evoked otoacoustic emissions (TEOAE). Usually the standard system ILO 88 Otodynamic Analyser is used, where until now emissions were analyzed subjectively. However, evaluation of signals may be difficult mainly in the hearing threshold area. In this article we describe a method to mathematically analyze registered emissions by correlation-filtering. This allows to better identify small specific responses, to further increase the sensitivity of TEOAE, and offers a more objective means for audiologic diagnoses.
Visual and Hearing Impairment Are Associated With Delirium in Hospitalized Patients: Results of a Multisite Prevalence Study
2021
Objective: Sensory deficits are important risk factors for delirium but have been investigated in single-center studies and single clinical settings. This multicenter study aims to evaluate the association between hearing and visual impairment or bi-sensory impairment (visual and hearing impairment) and delirium. Design: Cross-sectional study nested in the 2017 "Delirium Day" project. Setting and participants: Patients 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes, and hospices in Italy. Methods: Delirium was assessed with the 4AT (a short tool for delirium assessment) and sensory deficits with a clinical evaluation. …
[Paediatric cochlear implantation in the critical period of the auditory pathway, our experience].
2009
Numerous experimental and clinical studies have suggested a critical or sensitive period in which the auditory pathway develops its greatest potential in terms of plasticity and learning. Early cochlear implantation performed in prelingual deaf children in this period provides a better prognosis for language acquisition. The aim of this study is to show the importance of cochlear implantation before this critical period ends.We conducted an observational, longitudinal, retrospective study of 57 children suffering profound prelingual bilateral sensorineural hearing loss who had received Advanced Bionics implants at our ENT department between June, 1998, and November, 2006. Data on their audi…
