Variants of human CLDN9 cause mild to profound hearing loss
2021
Hereditary deafness is clinically and genetically heterogeneous. We investigated deafness segregating as a recessive trait in two families. Audiological examinations revealed an asymmetric mild to profound hearing loss with childhood or adolescent onset. Exome sequencing of probands identified a homozygous c.475G>A;p.(Glu159Lys) variant of CLDN9 (NM_020982.4) in one family and a homozygous c.370_372dupATC;p.(Ile124dup) CLDN9 variant in an affected individual of a second family. Claudin 9 (CLDN9) is an integral membrane protein and constituent of epithelial bicellular tight junctions that form semi-permeable, paracellular barriers between inner ear perilymphatic and endolymphatic compartment…
Bending Work Time: Curvilinear Relationship Between Working Time Dimensions and Psychological and Somatic Symptoms.
2020
Objectives Study examines the curvilinear associations of working time dimensions (working hours, time pressure, work schedules, and control of work time and pace) on psychological and somatic symptoms. Methods Representative Finnish Quality-of-Work-Life Surveys conducted in 2003, 2008 and 2013 were restricted to those (N=11,165) regularly working over 10h/week with more than one-year tenure in their job. Generalised additive models were utilised in analysis. Results Working hours had U-shaped relationships with psychosomatic symptoms, while time pressure had a threshold effect. Work pace control had linear effect. The effects of work time control and work schedules were insignificant. Ther…
From South to North? Mobility of Southern Italian Students at the Transition from the First to the Second Level University Degree
2018
In the last decades, the Italian University System has encountered several structural reforms aimed at making it more internationally competitive. Among them, the introduction of the University financial autonomy has triggered an “internal” competition among Universities to attract students from the entire country. Students’ enrollment at the first level has decreased significantly especially after the economic crisis of 2008, while the students’ migration from the South to the Central and Northern regions of the country has increased. These phenomena have created further inequalities within the country and a cultural and socio-economic loss for the South that does not appear to slow down. …
Fractional viscoelastic transversally isotropic Timoshenko beam
2014
In this paper the viscoelastic behavior of pultruded beams has been examined. Pultruded beams are constituted by a polymer infilled with reinforcement in longitudinal direction, while in the orthogonal direction no fiber are present for technological reasons. As a consequence the material has two different behaviors in longitudinal and in orthogonal directions. It follows that pultruded beams are transversally isotropic, and the shear deformation may not be neglected. Based upon the previous observations and assuming for Creep and/or Relaxation test the power law, the constitutive equations are ruled by fractional operators. From constitutive laws, and assuming the Timoshenko beam theory to…
New Insights into Segmental Packing, Chain Dynamics and Thermomechanical Performance of Aliphatic Polyurea Composites: Comparison between Silica Oxid…
2021
Polyurea (PU) is intrinsically reinforced by its microphase-separated morphology, giving its excellent mechanical properties. In this study, it is shown how a high-index PU formulation applies easy diffusion of hard segments into the soft phase of the PU matrix and tune its chain mobility. Moreover, the interaction of micro (>100 nm), nano (<100 nm) fillers with the microdomains and their thermomechanical properties are unraveled. Herein, nanosilica oxide (NS) and micro titanium (III) oxide (Ti2O3) are incorporated at low loadings into a solvent-free two-component aliphatic PU via insitu polymerization. While NS achieves an interfacial interaction with urea groups and forms a tight ha…
Subject-verb agreement of finite verbs in the present tense in written productions of Finnish secondary school learners of English as second language
2012
Subjektin ja verbin välinen kongruenssi on englannin kieliopin perusasioita, joka toimii tiettyjen säännön-alaisuuksien mukaisesti. Ilmiö on kuitenkin kiinnostava, sillä jopa edistyneetkin oppijat tekevät konguenssin tuottamisessa virheitä. Aiemmat tutkimukset ovat osoittaneet, että muun muassa subjektin kompleksisuudella ja semanttisilla piirteillä on vaikutusta kongruenssin hallintaan. Aiemmat tutkimukset eivät kuitenkaan ole ottaneet huomioon oppijoiden taitotasoja ja mahdollisia eroja kongruenssin tuottamisessa eri taitotasojen välillä Tämän tutkimuksen tarkoituksena on selvittää, miten yläkoulu-ikäisten taitotasoeroilla on vaikutusta kongruenssin tuottamiseen englannin kielessä. Tutkim…
Confocal laser scanning microscopy for the study of the morphological changes of the postextraction sites
2012
A better understanding of the remodeling process of postextraction sockets is essential in dental treatment planning. The aim of this study was to evaluate whether confocal laser scanning microscopy (CLSM) can be applied to imaging contour changes of postextraction sites, as well as to its quantification with image analysis of obtained three-dimensional images. This work describes a new application of the CLSM technique. The system used was the OLS3100-USS, LEXT model (Olympus((R))). CLSM was used for the surface analysis of the extraction site. The measurements taken with CLSM were: (1) mesio-distal distance, (2) alveolar ridge thickness, and (3) vestibular and lingual alveolar ridge heigh…
LEAVES OFNERIUM OLEANDERL. AS BIOACCUMULATORS OF POLYCYCLIC AROMATIC HYDROCARBONS (PAH) IN THE AIR OF PALERMO (ITALY): EXTRACTION AND GC-MS ANALYSIS,…
2005
Polycyclic Aromatic Hydrocarbons (PAH) were determined in the leaves of Nerium oleander L. an evergreen plant that occurs widely in both urban and rural areas, to monitor the degree of pollution in the urban area of Palermo (Italy) compared to remote areas. Twenty sites (urban roadside, urban, urban park, suburban and rural) in and around Palermo city were investigated. The purpose of this research was to investigate concentration levels and distribution patterns and relate them to possible sources. Analysis of 19 PAH was performed by gas chromatography/mass spectrometry (GCMS) using selected ion monitoring (SIM). The total amount of PAH ranged from 10 to 166 μg/Kg d.w. Each source gives ri…
Trace elements in thermomineral waters in Greece
2020
Trace elements have a fundamental role in natural and anthropogenic systems. In waters, they present a great variability of concentrations that mostly depends on the degree of gas-water-rock interactions and geochemical conditions such as pH, temperature, redox and/or exchange reactions, etc. Even though, they are present in very low contents in host-rocks, elevated concentrations in ground or surface waters may have a hazardous impact on human health and thus, it is important to both quantify and understand their behavior in natural systems. Here we present the results of about 300 cold and thermal mineral waters collected along the entire Hellenic territory. Physicochemical parameters (te…
Aeschylus apud Anytem. Coincidences and differences in the father-daughter relationship between A. Ag. 1551-1559 and AP 7.646 (G-P 7)
2021
En elepigrama AP 7.646 de Ániteresuenan ecos de un pasajeesquíleo: Ag. 1551-1559. En este trabajo repasamos cuáles son esas coincidencias formales y, sobre todo, examinamos los paralelismos y divergenciasentreel tema y el tono de ambos textos. En los dos se presenta con patetismo la intempestiva muerte de una hija antes de su padre, pero mientras que Erato en el epigrama se despide de él con amor, la predicción de Clitemnestra sobre la cálida acogida que Ifigenia brindará a Agamenón en el Hades resulta absolutamente irónica. Así, la referencia a la tragedia y, a través de ella, a Homero, no constituye una mera muestra de erudición, sino que Ánite refuerza, al oponerse al sentido del modelo,…
