Identification of calcium sensing receptor (CaSR) mRNA-expressing cells in normal and injured rat brain
2009
Calcium sensing receptor (CaSR), isolated for the first time from bovine and human parathyroid, is a G-protein-coupled receptors that has been involved in diverse physiological functions. At present a complete in vivo work on the identification of CaSR mRNA-expressing cells in the adult brain lacks and this investigation was undertaken in order to acquire more information on cell type expressing CaSR mRNA in the rat brain and to analyse for the first time its expression in different experimental models of brain injury. The expression of CaSR mRNAs was found mainly in scattered cells throughout almost all the brain regions. A double labeling analysis showed a colocalization of CaSR mRNA expr…
Prospective mathematics teachers’ self-referential metaphors as indicators of the emerging professional identity
2019
Ideals play a key role in a student teachers’ identity work. They form targets to strive for and a mirror for reflection. In this paper, we examine Finnish mathematics student teachers’ metaphors for the teacher’s role (N= 188). We classified the metaphors according to a model that identified teachers as subject matter experts, didactical experts, and pedagogical experts, with the addition of another two categories, self-referential and contextual. For the exploration of emerging professional identities, we studied the self-referential metaphors, which formed the most common category in the data. We observed that every third metaphor described either student teachers’ personalities or their…
Resistive state relaxation time in ZrO2(Y)-based memristive devices under the influence of external noise
2022
The effects of external digitally synthesized Gaussian noise on the resistive state relaxation time of a ZrO2(Y)-based memristive device when switching from a low resistance state to a high resistance state have been experimentally investigated. A nonmonotonic dependence of the resistive state relaxation time on the external noise intensity is found. This behavior is interpreted as a manifestation of the noise-enhanced stability effect previously observed in various complex systems with metastable states. It is shown that the experimental results agree satisfactorily with the theoretical ones. The presented results indicate the constructive role of external noise and its possible use as a m…
Structural and Functional Basis for Understanding the Biological Significance of P2X7 Receptor
2020
The P2X7 receptor (P2X7R) possesses a unique structure associated to an as yet not fully understood mechanism of action that facilitates cell permeability to large ionic molecules through the receptor itself and/or nearby membrane proteins. High extracellular adenosine triphosphate (ATP) levels—inexistent in physiological conditions—are required for the receptor to be triggered and contribute to its role in cell damage signaling. The inconsistent data on its activation pathways and the few studies performed in natively expressed human P2X7R have led us to review the structure, activation pathways, and specific cellular location of P2X7R in order to analyze its biological relevance. The ATP-…
Association between climate and new daily diagnoses of COVID-19
2020
AbstractBackgroundAlthough evidence is accumulating that climate conditions may positively or negatively influence the scale of coronavirus disease 2019 (COVID-19) outbreaks, uncertainty remains concerning the real impact of climate factors on viral transmission. Methods. The number of new daily cases of COVID-19 diagnosed in Verona (Italy) was retrieved from the official website of Veneto Region, while information on daily weather parameters in the same area was downloaded from IlMeteo website, a renowned Italian technological company specialized in weather forecasts. The search period ranged between March 1 to November 11, 2020. The number of new daily COVID-19 cases and meteorological da…
ON NEW ROLES IN DIGITAL ENVIRONMENTS: E-DOCTORS AND E-PATIENTS
2014
Medical communication can be both a dialogue between expert-to-expert or expert-to-laymen (Cordella, 2004; Bowles, 2006; Candlin, 2006; Maynard and Hudak 2008; Lutfey and Maynard 1998; Heritage 2010; Heritage and Clayman, 2010 among others). In this last exchange, the doctor treats the patient as an ‘understanding recipient of medical reasoning’ (Peräkylä 1997) and language is simplified for communicative reasons (Koch-Weser et al., 2009). Patients are assumed as having little medical knowledge, which affects their understanding of medical terms and eventually leads to poor communication and to patients’ dissatisfaction (Candlin, Bruton and Leather, 1974; Coulthard and Ashby, 1975; Todd and…
Emerging identity of Finnish nurse teachers: student teachers' narratives in a group exam.
2005
Summary In Finland students pursuing in Master's Degree Programme have a previous degree in nursing from polytechnics. Nurse teacher qualification also includes at least five year's experience of working in practice. This article concentrates on the conflicts student teachers brought up in a group exam as regards changing a nurse's identity into a teacher's identity in teacher training. The approach of the study on this group was narrative. The data were collected by videotaping two group exam situations (five hours in all) of volunteer student teachers ( N =5) during the last course (Nurse teacher's inquiring mind) of their nurse teacher studies in 2002. The material was transcribed and an…
Machine-readable entailments with the Italian 'prendere' construction expressing hitting and insulting events
2022
The Italian language features a little debated transitive construction with prendere ‘to take/to catch’ in which a prepositional phrase (PP) with an adverbial value occurs mandatorily (e.g. Lui prese a pugni Leo ‘He punched Leo’). Semantically, this construction often implies the use of physical force or verbal offence. In the hitting or insulting event, the notional subject generally is a [+ Human] Agent, whilst the notional direct object generally is a [+ Animate] Affectee ([1]: 4). It can be contended that prendere, which carries no literal meaning, is zero-valent and that the predicate assigning semantic roles is the PP. A computational tool will be illustrated, …
The influence of gender role on negotiation development and outcome
2007
PurposeThe main aim of this paper is to analyze the effect of gender differences on negotiation behaviour choice and, consequently, on its outcome. The analysis undertaken is first defined by distinguishing between sex and gender role. It gender role and not biological sex the factor that can have a direct impact on behaviour. With a contextual perspective, we have chosen the negotiation processes of strategic alliances as our contextual framework of analysis.Design/methodology/approachThe paper adopts a qualitative methodology, particularly case study analysis.FindingsA higher degree of complexity increases the perception of ambiguity, which then leads to the influence of gender in the neg…
The pathologist's role in the detection of rare variants of bladder cancer and analysis of the impact on incidence and type detection.
2018
BACKGROUND: Histology is one of the most important factors determining the prognosis of bladder cancers and rare variants are generally associated with decreased disease specific survival compared to pure transitional cell carcinomas. We believe that rare bladder cancer variants are likely underdiagnosed in the absence of a dedicated uro-pathologist in many centers. The objective of this study is to evaluate the contribution of a dedicated uro-pathologist on the identification of rare bladder cancer variants. METHODS: We retrospectively analyzed the clinical and histological records of all patients which underwent a radical cystectomy and lymph node dissection between January 2000 and Septe…
