High mobility group box 1 and markers of oxidative stress in human cord blood.

2019

Background Parturition induces considerable oxidative stress and many inflammatory mediators, such as high mobility group box 1 (HMGB1), are involved from the beginning of the pregnancy to birth. The aim of the present study was to evaluate serum cord blood concentration of diacron-reactive oxygen metabolites (d-ROM), biological antioxidant potential (BAP), and HMGB1 to investigate the perinatal oxidative status of neonates and correlation with mode of delivery, as well as the influence of labor. Methods The subjects consisted of 214 neonates delivered at University Hospital "G. Martino", Messina, in a 6 months period. Venous blood samples were collected from the umbilical cord after cord s…

Counselling for physical activity, life-space mobility and falls prevention in old age (COSMOS): protocol of a randomised controlled trial.

2019

IntroductionThe most promising way to promote active life years in old age is to promote regular participation in physical activity (PA). Maintaining lower extremity muscle function with good balance has been associated with fewer falls and the need of help from others. This article describes the design and intervention of a randomised controlled trial (RCT) investigating the effectiveness of a health and PA counselling programme on life-space mobility and falls rates in community-dwelling older adults at the Health Kiosk and/or Service Centre.Methods and analysisCommunity-dwelling men and women (n=450) aged 65 years and over with early phase mobility limitation will be recruited to a 24-mo…

Across regional disparities and beyond family ties: A Ghanaian middle class in the making

2021

Despite its fuzziness, the term middle class has become increasingly attractive in the past two decades, not only among social scientists and market analysts but also as a term of self-description ...

¿Movilidad inclusiva o accesibilidad inclusiva?

2017

<p>“La movilidad inclusiva” es parte de las prioridades políticas definidas por numerosos países europeos para referirse a la dimensión social del transporte o las políticas de movilidad cotidiana. De forma general, la inclusión se refiere a la cohesión social, que ha sido uno de los objetivos declarados de la Unión Europea desde el inicio de los años 2000. Como mecanismo para facilitar el acceso a las oportunidades (empleo, comercio, servicios, etc.), la movilidad individual es actualmente considerada un prerrequisito necesario para la participación de las personas en las actividades sociales. En contraste, la inmovilidad o “ausencia de movilidad” sería un factor de exclusión social.…

La verificació audiovisual en el procés d’evolució de les redaccions televisives: Al Jazeera i el trànsit del satèl·lit a l’estructura de núvol

2021

With the spread of the digital sphere and the proliferation of images from indirect sources that can be accessed by systems and users, verification routines have become essential to ensure media corporations' credibility. The advances in artificial intelligence which allow automated fact-checking (AFC) initiatives to be created help detect falsehoods, but they do not eliminate the need for human intervention. On the contrary, information professionals are necessary, and their functions increasingly include procedures such as mediating in videos and images. This study analyses the evolution of verification routines in audiovisual journalism and how new techniques have influenced the percepti…

Role of photoactive layer morphology in high fill factor all-polymer bulk heterojunction solar cells

2011

We report on the realization of all-polymer solar cells based on blends of poly(3-hexylthiophene-2,5-diyl) (P3HT) as a donor and poly{[N,N'-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (P(NDI2OD-T2)) as an acceptor. High fill factors are demonstrated for the first time in this class of devices suggesting high dissociation efficiency for the bounded electron-hole pairs and balanced electron and hole mobility along the thin films. The use of the high-mobility n-type P(NDI2OD-T2) polymer enables us to overcome one of the problems limiting the efficiency of all-polymer solar cells, resulting in fill factors comparable with those reported for …

Analysis of drugs including illicit and new psychoactive substances in oral fluids by gas chromatography-drift tube ion mobility spectrometry

2021

Abstract In this study, a gas chromatograph (GC) has been coupled to a drift tube ion mobility spectrometer (IMS) in order to develop an analytical procedure for the determination of psychoactive substances in oral fluids. Working parameters, including the GC-IMS interface ones, were adjusted in order to obtain sensitive and robust signals. A volume of 500 μL of oral fluid was extracted with 250 μL chloroform and, after centrifugation, were injected into the GC-IMS system. Amphetamine, methylone, α-PVP, ketamine, lidocaine, MPHP, cocaine, THJ-2201, and 5F-ADB were employed as model compounds, providing limits of detection from 6 to 15 μg L−1 and recoveries from 70 to 115% for field oral flu…

Determination of the new psychoactive substance dichloropane in saliva by microextraction by packed sorbent – Ion mobility spectrometry

2018

Abstract A simple procedure based on microextraction by packed sorbent (MEPS) has been proposed for the extraction of dichloropane in oral fluids and its determination by ion mobility spectrometry (IMS). Extraction conditions such as type of sorbent (octyl and octadecyl silica), sample pH, number of sample loadings, and elution volume were evaluated to obtain the most appropriate values. Dichloropane was extracted from saliva samples using C8 MEPS, loading with 100 μL sample (adjusted to pH 7) in 4 cycles, washing with 100 μL deionized water, and eluting with 50 μL 2-propanol in 10 cycles. The proposed MEPS procedure has been validated in terms of linearity, accuracy, and precision. A limit…
