Characterization of a CZT focal plane small prototype for hard X-ray telescope

2005

The promise of good energy and spatial resolution coupled with high efficiency and room temperature operation has fuelled a large international effort to develop cadmium zinc telluride (CZT) for hard X-ray applications. We are involved on the development of a hard X-ray telescope based on multilayer optics and focal plane detector operative in the 10-80 keV energy range. This telescope requires a high efficiency focal plane providing both fine spatial resolution and spectroscopy with a compact and robust design. This paper reports preliminary results on the characterization both in spectroscopic and spatial response of two small pixellated CZT detectors (10times10times1 mm3 and 10times10tim…

Understanding the Interactions of Guanine Quadruplexes with Peptides as Novel Strategies for Diagnosis or Tuning Biological Functions

2023

Guanine quadruplexes (G4s) are nucleic acid structures exhibiting a complex structural behavior and exerting crucial biological functions, in both cells and viruses. The specific interactions of peptides with G4s, as well as the understanding of the factors driving the specific recognition, are important for the rational design of both therapeutic and diagnostic agents. In the present minireview, we examine the most important studies dealing with the interactions between G4s and peptides, highlighting the strengths and limitations of the present analytic approaches. We also show how the combined use of high-level molecular simulation techniques and experimental spectroscopy represents the b…

Influence of a flexibility training program on psychophysical health of elderly women

2014

Aim: The aim of this study was to assess the influence of a specific flexibility training program on the spinal health status and the health-related quality of life (HRQoL) in female older subjects. Methods: Thirty older women were recruited in a senior centre of Palermo and randomly assigned in two groups: trained group [TG] (n: 17; age: 68.35±6.04 years; BMI: 27.28±3.08) and control group [CG] (n: 13; age: 69.69±7.94 years; BMI: 27.88±2.81). TG was trained for 8 weeks by two sessions/week. In particular, every training session included three phases: warm up (~10 min), central period (~50 min) including specific exercises to train spinal flexibility, and cool down (~10 min)1. CG did not pe…

Sportomics: metabolomics applied to sports. The new revolution?

2019

Sportomics is the application of metabolomics in sports to investigate the metabolic effects of physical exercise on individuals, whether they are professional athletes or not. Metabolomics is one of the "omics" sciences that provide a picture of the metabolic state of a person in physiological or pathological conditions. This is achieved through the analysis of metabolites present in a biological fluid, such as saliva, blood, feces, and urine. The authors revised the recent literature concerning this topic and discussed the useful information that sportomics can provide and the limits of the current experimental settings. Furthermore, in the future, sportomics analyses could be used to pre…

Qualitative mucin disorders in patients with primary Sjögren's syndrome:a literature review

2020

Background It is a common opinion that Primary Sjögren Syndrome (pSS) damages the exocrine glands and determines the reduction of secreted saliva, some studies show that there are qualitative anomalies of the mucins produced in saliva, including MUC7, MUC5B, MUC1. The purpose of this study is to trace all the information useful to establish whether there is a qualitative or quantitative defect of the mucins in the pSS. Material and Methods We reviewed the literature by looking for publications relevant to the topic in electronic databases. Sixteen articles met the search criteria. The studies were divided into two categories, those that studied the rheological characteristics of the saliva …

Behind the scenes of artificial intelligence: a study of micro-work platforms in France

2019

Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…

A large ameloblastic fibro-odontoma of the right mandible

2007

The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults with no sex predilection and locates most often in the posterior segment of the mandible. A painless swelling is the most common clinical sign. Radiologically, ameloblastic fibro-odontoma shows a circumscribed radiolucency, which contains radio-opaque foci of various sizes and shapes. Histological examination reveals a fibrous soft tissue, islands of odontogenic epithelium and a disordered mixture of dental tissues. The tumor produces enamel or enamel matrix, dentin and cementum. The treatment of ameloblastic fibro-odontomas usually consists of enucleation or surgical cure…
