Individual alpha peak frequency, an important biomarker for live Z-Score training neurofeedback in adolescents with learning disabilities
2021
Learning disabilities (LDs) have an estimated prevalence between 5% and 9% in the pediatric population and are associated with difficulties in reading, arithmetic, and writing. Previous electroencephalography (EEG) research has reported a lag in alpha-band development in specific LD phenotypes, which seems to offer a possible explanation for differences in EEG maturation. In this study, 40 adolescents aged 10–15 years with LDs underwent 10 sessions of Live Z-Score Training Neurofeedback (LZT-NF) Training to improve their cognition and behavior. Based on the individual alpha peak frequency (i-APF) values from the spectrogram, a group with normal i-APF (ni-APF) and a group with low i-APF (li-…
Imaging of VSOP labeled stem cells in agarose phantoms with susceptibility weighted and T2* weighted MR Imaging at 3T: determination of the detection…
2013
Objectives This study aimed to evaluate the detectability of stem cells labeled with very small iron oxide particles (VSOP) at 3T with susceptibility weighted (SWI) and T2* weighted imaging as a methodological basis for subsequent examinations in a large animal stroke model (sheep). Materials and Methods We examined ovine mesenchymal stem cells labeled with VSOP in agarose layer phantoms. The experiments were performed in 2 different groups, with quantities of 0–100,000 labeled cells per layer. 15 different SWI- and T2*-weighted sequences and 3 RF coils were used. All measurements were carried out on a clinical 3T MRI. Images of Group A were analyzed by four radiologists blinded for the num…
Immune Modulating Effects of NKT Cells in a Physiologically Low Dose Leishmania major Infection Model after αGalCer Analog PBS57 Stimulation
2014
Leishmaniasis is a parasitic infection affecting ∼12 million people worldwide, mostly in developing countries. Treatment options are limited and no effective vaccines exist to date. Natural Killer T (NKT) cells are a conserved innate-like lymphocyte population with immunomodulating effects in various settings. A number of reports state a role of NKT cells in different models of Leishmania infection. Here, we investigated the effect of NKT cells in a physiologically relevant, intradermal low dose infection model. After inoculation of 103 infectious-stage L. major, comparable numbers of skin-immigrating NKT cells in both susceptible BALB/c mice and resistant C57BL/6 mice were noted. Compared …

Serological and molecular identification of Legionella spp. isolated from water and surrounding air samples in Italian healthcare facilities
2016
Abstract Background Legionella is an intracellular microorganism living in natural and artificial aquatic environments. Although its transmission to humans is linked to the inhalation of contaminated aerosols, there is no validated air sampling method for the control and prevention of the disease. The aim of the present study was to provide more information on the distribution of Legionella spp. in indoor environments and to determine whether the same Legionella strains are isolated from air and water samples. Methods Ten healthcare facilities located in seven regions of Italy were enrolled. The serological typing of Legionella spp. from water samples and the surrounding air by active and p…
Null subjects in generative grammar: A synchronic and diachronic perspective
2018
This book considers the null-subject phenomenon, whereby some languages lack an overtly realized referential subject in specific contexts. In generative syntax-the approach adopted in this volume-the phenomenon has traditionally been explained in terms of a ‘pro-drop’ parameter with associated cluster properties; more recently, however, it has become clear that pro-drop phenomena do not always correlate with all the initially predicted cluster properties. This volume returns to the centre of the debate surrounding the empirical phenomena associated with null subjects. Experts in the field explore the cluster properties associated with pro-drop; the types of null category involved in null-su…
Epistemic uses of the pretérito pluscuamperfecto in La Paz Spanish
2020
This paper explores epistemic-evidential uses of the pluperfect, i.e. pretérito pluscuamperfecto, in La Paz Spanish. The pretérito pluscuamperfecto displays functions of a reported evidential form, conforming to results from previous studies on Argentinian Spanish (Bermúdez 2008; Speranza 2014) and, furthermore, is used according to a previously unnoticed inferential evidential function. Using theoretical frameworks from Kockelman (1957) and Bergqvist (2018), this paper describes the configuration of participant roles and event types implied in the different evidential functions of the pretérito pluscuamperfecto.
Estereotipos asociados al cuerpo humano: análisis de aplicaciones móviles usadas en la educación físico-deportiva
2022
Institutions and educators are massively and uncritically integrating digital curricular materials in their teaching praxis. This article aims to uncover whether health and fitness APP images convey or legitimize stereotypes linked to bodies, focusing on gender, race, somatotype and physical activity practice. We also analyse whether these apps are adequate for the recommended age or whether they are designed by physical education professionals. For that purpose, we designed a descriptive, comparative study based on content analysis on a sample of 373 images from 128 apps selected through a PRISMA review and a pilot test. Our results report that bodies reproduce a series of stereotypes: of …
Analysis of HLA-DRB1,DQA1,DQB1 haplotypes in Sardinian centenarians
2008
Some genetic determinants of longevity might reside in those polymorphisms for the immune system genes that regulate immune responses. Many longevity association studies focused their attention on HLA (the human MHC) polymorphisms, but discordant results have been obtained. Sardinians are a relatively isolate population and represent a suitable population for association studies. Some HLA-DR and DQ alleles form very stable haplotypes with a strong linkage disequilibrium. In a previous study on Sardinian centenarians we have suggested that HLA-DRB1 *15 allele might be marginally associated to longevity. HLA-DR,DQ haplotypes are in strong linkage disequilibrium and well conserved playing a ro…
Reliability and methodology of quantitative assessment of harvested and unharvested patellar tendons of ACL injured athletes using ultrasound tissue …
2019
Ultrasound tissue characterization (UTC) imaging has been previously used to describe the characteristics of patellar and Achilles tendons. UTC imaging compares and correlates successive ultrasonographic transverse tendon images to calculate the distribution of four color-coded echo-types that represent different tendon tissue types. However, UTC has not been used to describe the characteristics of patellar tendons after anterior cruciate ligament reconstruction (ACLR). The aim of this cross-sectional study was to assess the intra and inter-rater reliability of the UTC in unharvested and harvested patellar tendons of patients undergoing ACLR. Intra and inter-rater reliability of both UTC da…
