Corrosion and wear resistance of coatings produced on AZ31 Mg alloy by plasma electrolytic oxidation in silicate-based K2TiF6 containing solution: Ef…

2022

Abstract In this research, plasma electrolytic oxidation coatings were prepared on AZ31 Mg alloy in a silicate-based solution containing K2TiF6 using bipolar and soft sparking waveforms with 10, 20, and 30% cathodic duty cycles. The coatings displayed a net-like surface morphology consisted of irregular micro-pores, micro-cracks, fused oxide particles, and a sintered structure. Due to the incorporation of TiO2 colloidal particles and the cathodic pulse repair effect, most of the micro-pores were sealed. Long-term corrosion performance of the coatings was investigated using electrochemical impedance spectroscopy during immersion in 3.5 wt.% NaCl solution up to 14 days. The coating grown by t…

Diagnostic performance of gadobenate dimeglumine enhanced MR angiography of the iliofemoral and calf arteries: a large-scale multicenter trial

2007

OBJECTIVE. The purpose of this study was to compare gadobenate dimeglumine–enhanced MR angiography and unenhanced time-of-flight MR angiography for the detection of significant peripheral arterial occlusive disease using digital subtraction angiography as our reference standard. SUBJECTS AND METHODS. Two hundred seventy-two patients underwent MR angiography and digital subtraction angiography of the iliofemoral arteries. MR angiography was performed before (2D time-of-flight acquisitions) and after (spoiled gradient-echo acquisitions) the administration of 0.1 mmol/kg of gadobenate dimeglumine at 1–2 mL/s. Contrast-enhanced MR angiography and digital subtraction angiography of the calf arte…

Anxiety symptoms and mild cognitive impairment among community-dwelling older adults from low- and middle-income countries.

2021

Abstract Aim Anxiety may be a risk factor for mild cognitive impairment (MCI) but there is a scarcity of data on this association especially from low- and middle-income countries (LMICs). Thus, we investigated the association between anxiety and MCI among older adults residing in six LMICs (China, Ghana, India, Mexico, Russia, South Africa), and the mediational effect of sleep problems in this association. Methods Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analy…

Riflessioni e traiettorie di ricerca interdisciplinari sulla transizione digitale

2022

The contribution introduces the topic covered by vol. 12 of AGATHÓN through essays, studies, research and projects on Innovability©® | Digital Transition to investigate the current widespread transformation that unites dichotomies (analogue and digital), enhances oxymorons (artificial intelligence), creates paradoxes (materiality of the intangible), while indiscriminately involving architecture, humanities and social sciences, anthropology, sociology, ecology, biology, physical-mathematical sciences and neurosciences, with impacts that – while already visible today and accelerated in part by the extraordinary global health emergency – will become even more evident in the medium and long ter…

Studenti universitari: una riflessione

2021

The presence of foreign students in Italian universities intersects with the debate on citizenship, cooperation, integration and the opportunities offered by the labour market. Moreover, talking about foreign students enrolled in Universities implies the need to remember the heterogeneity between the types of students in relation not only to their origin, their motivations in choosing a course, but also to the problems connected to their legal status. In the text, reference will be made to data on foreign students who, at the end of their high school education, decided to continue their university studies by enrolling in a first-level or single-cycle university course in Italian universitie…

Sleep problems and mild cognitive impairment among adults aged ≥50 years from low- and middle-income countries

2021

Background-\ud \ud The limited available literature suggests that sleep problems are linked to an increased risk of mild cognitive impairment (MCI). However, this association has been little studied to date in low-income settings.\ud \ud Objective-\ud \ud To investigate the association between sleep problems and MCI in a large sample of adults from six low-and middle-income countries (LMICs).\ud \ud Design-\ud \ud Cross-sectional.\ud \ud Setting-\ud \ud Study on Global Ageing and Adult Health (SAGE).\ud \ud Subjects-\ud \ud 32,715 individuals aged ≥50 years with preservation in functional abilities [age range 50–114 years; 51.7% females].\ud \ud Methods-\ud \ud MCI was defined using the Nat…

Physical multimorbidity predicts the onset and persistence of anxiety: A prospective analysis of the Irish Longitudinal Study on Ageing.

2022

Background: The aims of the present study were to examine prospective associations of multimorbidity (i.e., >= 2 chronic conditions) at baseline with incident and persistent anxiety over a two-year follow-up period among Irish older adults, and to quantify the extent to which sleep, pain, and disability mediate the multimorbidity-anxiety relationship.& nbsp;Methods: Data from The Irish Longitudinal Study on Aging (TILDA) conducted between 2009 and 2011 with a follow-up after two years were analyzed. Anxiety referred to score >=& nbsp;8 on the anxiety section of the Hospital Anxiety and Depression Scale. Lifetime diagnosis of 14 chronic conditions was obtained. Outcomes were in…
