Determining a healthy reference range and factors potentially influencing PRO-C3 – A biomarker of liver fibrosis
2021
Background & Aims Progressive fibrosis has been identified as the major predictor of mortality in patients with non-alcoholic fatty liver disease (NAFLD). Several biomarkers are currently being evaluated for their ability to substitute the liver biopsy as the reference standard. Recent clinical studies in NAFLD/NASH patients support the utility of PRO-C3, a marker of type III collagen formation, as a marker for the degree of fibrosis, disease activity, and effect of treatment. Here we establish the healthy reference range, optimal sample handling conditions for both short- and long-term serum storage, and robustness for the PRO-C3 assay. Methods PRO-C3 was measured in 269 healthy volunteers…
Nonlocal dispersion anomalies of Dyakonov-like surface waves at hyperbolic media interfaces
2016
Dyakonov-like surface waves (DSWs) propagating obliquely on an anisotropic nanostructure have been theoretically proved in a few cases including 2D photonic crystals and metal-insulator (MI) layered metamaterials. Up to now, the long-wavelength approximation has been employed in order to obtain effective parameters to be introduced in the Dyakonov equation, which is largely restricted to material inhomogeneities of a few nanometers when including metallic elements. Here, we explore DSWs propagating obliquely at the interface between an insulator and a hyperbolic metamaterial, the latter consisting of a 1D MI bandgap grating using realistic slab sizes. We found unexpected favorable condition…
Narrating Migration
2017
Numerous studies evidence how migration represents a critical event in the subject’s life (Akhtar , 1999; Baptiste , 1987; Scabini & Rossi , 2008). Such an event is characterised by various phases, some of which reflect the loss of culture, family of origin, language and some of which concern adaptation to the new environment (Hertz, 1981, 1993; Kaёs, 1993; Sluzky, 1992). To foster routes of growth and constructive interaction with the new environment, it is necessary for immigrants to strengthen the process of self-awareness. This is fundamental if learning is to be considered transformative (Freire, 1970). According to what is proposed in this paper, such a process of self-awareness i…
Weighted Evaluation Framework for Cross-Platform App Development Approaches
2016
Cross-platform app development is very challenging, although only two platforms with significant market share (iOS and Android) remain. While device fragmentation – multiple, only partly compatible versions of a platform – has been complicating matters already, the need to target different device classes is a new emergence. Smartphones and tablets are relatively similar but app-enabled devices such as TVs and even cars typically have differing capabilities. To facilitate usage of cross-platform app development approaches, we present work on an evaluation framework. Our framework provides a set of up-to-date evaluation criteria. Unlike prior work on this topic, it offers weighted assessment …
Current Trends in the Exploitation of Mature Gas Fields to Capitalize the Energy Potential
2021
The exploitation of mature natural gas fields is a topical issue in the industry given that most of the production, about 70%, comes from these reservoirs. Implementation of the project management into the exploitation of mature gas reservoirs has a notable ascension because of the fact that in the execution of the operational programs always has developed a mechanism to achieve the objectives in a sustainable manner. The project management in gas industry it is known as rehabilitation concept or integrated reservoir development, which has a major impact on increasing the recovery factor. The paper intends to present the current trends in the exploitation of mature gas fields by applying th…
Positive/negative symptomatology and experimental measures of attention in schizophrenic patients.
1993
In a search for an external validation of the negative syndrome construct and the attentional impairment item on Andreasen's scale, 49 unmedicated schizophrenic patients were administered the Span of Apprehension Test and a Continuous Performance Test with two levels of difficulty. This schizophrenic sample performed significantly more poorly on the attentional tests than a comparable group of 27 healthy control subjects. Depending on the difficulty of the test we found a number of significant correlations between the SANS composite score and the pertaining attentional impairment item on the one hand and experimental indices of attentional functioning on the other hand, which might corrobor…
A multi-analytical non-invasive and micro-invasive approach to canvas oil paintings. General considerations from a specific case
2017
Abstract The investigation of artwork to understand story, state of conservation and to know about the composing materials is an issue that is getting growing attention in specialized literature. From a methodological point of view the scientific community is trying to reach a common proposal that could contribute to define a Standard Operating Procedure (SOP) for the application of portable non-invasive and microinvasive techniques for in-situ analyses. In this paper the oil painting on canvas “St. Girolamo nello studio” by Nicolo Buttafoco was investigated to known the materials and techniques used by the artist as well as to evaluate its preservation status. The survey has been conducted…
Order and Chaos in the Statistical Mechanics of the Integrable Models in 1+1 Dimensions
1991
This paper was presented at the meeting under this title. But, originally, the more cumbersome ‘Quantum chaos — classical chaos in k-space: thermodynamic limits for the sine-Gordon models’ was proposed. Certainly this covers more technically the content of this paper.
79. Amyloid-PET analysis based on tissue probability maps
2018
Purpose The regional quantification of amyloid burden is crucial for the clinical diagnosis of Alzheimer’s disease [1]. The best method to evaluate regional amyloid deposition in PET is through the use MR imaging for brain space normalization. However, since MR imaging is not always available in the clinical practice, a MR-less methodology is needed in order to compute semi-quantitative and analyze regional amyloid burden. Methods Forty-four patients with clinical evidence of dementia, underwent 18F-Florbetaben PET (FBB-PET), FDG-PET, neuropsychological assessment and cerebrospinal fluid analysis. We implemented a methodology that uses SPM12 to import and normalize the FBB-PET images in Mon…
Anxiety disorders and other psychiatric subgroups in patients complaining of dizziness.
2003
Two hundred and two consecutive patients with dizziness were evaluated using blind neuro-otological testing and examination, blind psychiatric examination, including structured interviews (according to DSM-IV), the Symptom Check-List (SCL 90 R), and the State-Trait Anxiety Inventory (STAI). In 28% of the patients (N=50) dizziness was of organic origin (O group); in 55.3% (N=99) of psychogenic origin (P group) and in 16.8% comorbid psychiatric disorders were found (Mixed group). In 5.3% (N=10) neither organic nor psychiatric results could be found, which could explain the dizziness (Ideopathic group). Compared with the Organic group the patients with psychiatric disorders (P and Mixed group)…
