Scalable Bio Marker Combinations for Early Stroke Diagnosis: A Systematic Review
2021
Background: Acute stroke treatment is a time-critical process in which every minute counts. Laboratory biomarkers are needed to aid clinical decisions in the diagnosis. Although imaging is critical for this process, these biomarkers may provide additional information to distinguish actual stroke from its mimics and monitor patient condition and the effect of potential neuroprotective strategies. For such biomarkers to be effectively scalable to public health in any economic setting, these must be cost-effective and non-invasive. We hypothesized that blood-based combinations (panels) of proteins might be the key to this approach and explored this possibility through a systematic review.Metho…
Respondent Uncertainty and Ordering Effect on Willingness to Pay for Salt Marsh Conservation in the Brest Roadstead (France)
2017
International audience; This paper explores the potential link between the sensitivity of willingness to pay (WTP) to the order of presenting bid amounts in contingent valuation questions (ordering effect) and respondent uncertainty. The resource being valued is a public project to protect salt marshes against the spread of an invasive aquatic plant in the Brest roadstead (France). Valuation uncertainty is captured through a variant of payment card format where respondents are given the opportunity to report their WTP as either a single value (Option A) or an interval of values (Option B). The ordering effect is tested using both parametric models that ignore and control for the potential s…
Nature and origin of natural Zn clay minerals from the Bou Arhous Zn ore deposit: Evidence from electron microscopy (SEM-TEM) and stable isotope comp…
2016
International audience; Zn-clay minerals have been found in the non-sulfide deposit of Bou Arhous (High Atlas, Morocco). They occur as white or ochre clays embedding willemite (Zn2SiO4) and are commonly associated to red detrital clays in karstic cavities. Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) with Energy Dispersive X-ray (EDX) analyses were combined in order to characterize the clay minerals and to determine the mechanism of their formation. XRD patterns on oriented and powdered clays and Fourier Transform Infrared (FTIR) spectroscopic analyses suggest that fraipontite is the major Zn clay phase (with some smectite interstrat…
Boccaccio, «Ninfale fiesolano» 309, 5-8: per la storia di un tópos fra tradizione classica e suggestioni medievali
2022
Questa nota, alla luce della lettura e dell’interpretazione di un passo del «Ninfale fiesolano» del Boccaccio (309, 5-8), ripercorre la fortuna del motivo della “reciprocità” amorosa e, in particolare, dell’intimo rapporto che fa sì che “due” giovani innamorati, legati da affinità di costumi, età, bellezza, siano come “una” sola persona. Un motivo molto antico, questo, che affonda le sue radici nella tradizione biblica e nella letteratura classica, e che conoscerà ampia fortuna nel Medioevo latino e volgare. Fra i testi che vengono proposti e analizzati si segnalano, soprattutto, le «Metamorfosi» di Ovidio, l’«Ero e Leandro» di Museo, il «Narcissus», il «Pamphilus», l’«Alda» di Guglielmo di…
No le digan loco a Bill. Sobre internalismo y externalismo de las razones para la acción
2011
En este trabajo analizaré dos concepciones de la racionalidad práctica – bien conocidas y debatidas en la literatura contemporánea – con el propósito de mostrar que una es superior a la otra. La primera concepción, que será la defendida en este trabajo, es una concepción denominada “formal” o “internalista”, mientras que la segunda podría denominarse “sustancial” o “externalista”. En particular, defenderé una concepción formal moderada, análoga a la de Bernard Williams, según la cual Juan tiene una razón para hacer X, si y sólo si hacer X representa un medio (considerado) suficiente para satisfacer un deseo que él tendría luego de haber realizado el procedimiento argumentativo racional. In …
La voce, il gesto, la scena. Elementi teatrali nelle commedie latine del XII e XIII secolo
2019
In questo volume, dopo aver delineato un panorama organico delle cosiddette commedie latine elegiache del XII e XIII secolo, viene discussa l'antica questione della reale possibilità di rappresentare questi testi, cercando di mostrare - anche sulla base di alcune glosse di Arnolfo di Orléans e un'intera serie di spie e indizi interni dei testi stessi - come è ipotizzabile una rappresentazione teatrale, almeno per alcune di queste commedie. Gli argomenti qui trattati riguardano l'alternanza, nelle composizioni comico-elegiache, tra parti narrative e sezioni monologiche e / o dialogiche; le didascalie "interne"; possibili relazioni con la tradizione giullaresca; la convivenza, all'interno di …
Microevolution of eastern palaearctic Grey tits as indicated by their vocalizations (Parus [Poecile]: Paridae, Aves) I. Parus montanus: Contributions…
2009
Within the Palaearctic Region, the Willow tit (Parus montanus) displays four vicariant forms of territorial song. 1. “Alpine” form (pure single-frequency whistles, Fig. 5: 1) in the Alps and adjacent mountains to the East. 2. “Lowland” or “Normal” form (frequency change from high to low within one note, Fig. 5: 2) in the other parts of NW, Central and SE Europe. 3. In populations of N and E Europe as well as of W and E Siberia every individual bird uses - so far as known - both song types; this “Siberian” form (Figs. 1, 2) includes intergrades (Fig. 3). The comparatively type-rich Siberian repertoire is found in a vast area from N and E Europe to the Amur River and Ussuriland in Siberia. 4.…
Increased Vascularity in Cervicovaginal Mucosa with Schistosoma haematobium Infection
2011
Background Close to 800 million people in the world are at risk of schistosomiasis, 85 per cent of whom live in Africa. Recent studies have indicated that female genital schistosomiasis might increase the risk of human immunodeficiency virus (HIV) infection. The aim of this study is to quantify and analyse the characteristics of the vasculature surrounding Schistosoma haematobium ova in the female genital mucosa. Methodology/Principal Findings Cervicovaginal biopsies with S. haematobium ova (n = 20) and control biopsies (n = 69) were stained with immunohistochemical blood vessel markers CD31 and von Willebrand Factor (vWF), which stain endothelial cells in capillary buds and established blo…
Effect of antiangiogenic treatment on peritoneal endometriosis-associated nerve fibers

Expression of the endothelial markers PECAM-1, vWf, and CD34 in vivo and in vitro.
2002
EC culture models are essential to study pathological alterations of endothelial cells (ECs) in pulmonary vascular diseases under standardized conditions. Nevertheless, little is known about the spectrum of alterations of vessel-specific endothelial phenotypes in monolayer cultures. For the comparative study of endothelial markers in vivo and in vitro we investigated immunohistochemically the expression of PECAM-1, vWf, and CD34 by pulmonary ECs in vivo and in stimulated/unstimulated human umbilical vein endothelial cells (HU-VEC) and human pulmonary microvascular endothelial cells (HPMEC). In vivo, vessel type-specific expression patterns were found for vWf and CD34, while PECAM-1 was homo…
