Le valenze della Danza Movimento Terapia in presenza e a distanza. Corpo e relazioni durante la pandemia del COVID-19

2022

Elena Mignosi e Fernando Battista approfondiscono nella loro articolo le specificità della Danza Movimento Terapia (DMT) e i suoi numerosi ambiti applicativi (educativo, formativo clinico, terapeutico, sociale/inclusivo , riabilitativo). Conducono quindi una riflessione sulle modalità in presenza e da remoto, individuando quale efficacia possa avere partecipare ad un esperienza artisctico-creativa e corporea attraverso uno schermo. La pandemia da Covid 19 ha infatti reso necessario ripensare quelli che erano ritenuti i punti cardine del setting di DMT e di individuare nuove forme di interazione. Infine essi presentano brevemente i capitoli della rivista che costituiscono gli Atti del Conveg…

Long-term anti-tumour necrosis factor therapy reverses the progression of carotid intima–media thickness in female patients with active rheumatoid ar…

2009

The objective of the study is to evaluate the effect of TNF inhibition on carotid thickness over a 2-year period. 144 women with RA diagnosed according to ACR criteria, without clinical evidence of cardiac and/or vascular disease were enrolled and compared with 78 matched controls. All patients received methotrexate (15–20 mg weekly) for 3 months. Responders (n = 79) continued to be treated with methotrexate, non-responders (n = 40) moved to methotrexate plus a TNF alpha antagonist. Echosonographic studies of carotids were obtained before and after 2-year follow-up. A significant decrease of ca-IMT was observed in anti-TNF-treated patients (P < 0.001); on the other hand, no significant vari…

Colorectal cancer with microsatellite instability: Right-sided location and signet ring cell histology are associated with nodal metastases, and extr…

2021

Colorectal cancer (CRC) with microsatellite instability (MSI) accounts for 15-18 % of all CRCs and represents the category with the best prognosis. This study aimed at determining any possible clinical/pathological features associated with a higher risk of nodal metastasization in MSI-CRC, and at defining any possible prognostic moderators in this setting. All surgically resected CRCs of the last 20 years (mono-institutional series) with a PCR-based diagnosis of MSI, with and without nodal metastasis, have been retrieved for histological review, which was performed following WHO guidelines. Furthermore, the most important prognostic moderators have been investigated with a survival analysis…

Stroop task performance across the lifespan: High cognitive reserve in older age is associated with enhanced proactive and reactive interference cont…

2020

Abstract Susceptibility to interference increases with age but there is large inter-individual variability in interference control in older adults due to a number of biological and environmental factors. The present study aims at analyzing behavior and ERPs in a Stroop interference task with increasing difficulty in a sample of 246 young, middle-aged and healthy old participants. The old age group was divided into three subgroups based on performance scores. The results show a gradual performance reduction with increasing age and task difficulty. However, old high performers reached a performance level comparable to middle-aged subjects. The contingent negative variation (CNV) reflecting pr…

Effect of TiO2 and Al2O3 Addition on the Performance of Chitosan/Phosphotungstic Composite Membranes for Direct Methanol Fuel Cells

2023

Composite chitosan/phosphotungstic acid (CS/PTA) with the addition of TiO2 and Al2O3 particles were synthesized to be used as proton exchange membranes in direct methanol fuel cells (DMFCs). The influence of fillers was assessed through X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, liquid uptake, ion exchange capacity and methanol permeability measurements. The addition of TiO2 particles into proton exchange membranes led to an increase in crystallinity and a decrease in liquid uptake and methanol permeability with respect to pristine CS/PTA membranes, whilst the effect of the introduction of Al2O3 particles on the characteristics of membranes is almost the op…

CORRELATION BETWEEN THE CHEMICAL-PHYSICAL PROPERTIES OF CNT AND MACROSCOPIC PROPERTIES OF RELATED NANOCOMPOSITES: A STATISTICAL APPROACH

2014

In the frame of this work, two different samples of CNTs, namely CNT 1 and CNT 2, were synthesized [1] with different degree of purity and aspect ratio and used as fillers either without any treatment or after a plasma-oxidation, to prepare polycarbonate (PC)-based nanocomposites by melt mixing. The influence of plasma treatment, filler content and type of CNTs on the mechanical, dynamic-mechanical, and electrical properties of the materials was assessed by a two level full factorial design. The morphological analysis carried out by SEM and TEM evidenced the formation of a nanohybrid structure when oxidized CNTs were used as filler. Generally speaking, CNT 2 showed the best dispersion and t…

A NOVEL APPROACH IN COLORECTAL CANCER AND DIABETES MANAGEMENT: ROLE OF METFORMIN AND RAPAMYCIN

Abstract The link between colorectal cancer (CRC), diabetes mellitus (DM) and inflammation is well established, and polytherapy, including rapamycin, has been commonly adopted. However, due to the relatively weak response of CRC to rapamycin, combination with other molecules including metformin has become a potentially promising approach. This study is a novel approach that aimed at assessing the effect of a combination therapy of metformin and rapamycin on the control or prevention of colorectal cancer in diabetic animals, in presence or absence of probiotics. Fifty NOD/SCIDs male mice developed xenograft by inoculating HCT116 cells into the flank; they were equally divided into diabetics …

Induced Chirality in Confined Space on Halogen Gold Complexes

2015

The solubilization of HAuCl4 in toluene within optically active reverse micelles and lamellar structures formed by (1R,2S)-Dodecyl(2-hydroxy-1-methyl-2-phenylethyl)- dimethylammonium bromide (DMEB) has allowed us to evidence the complex phenomenology accompanying the confinement of Au salt within these nanostructures. Together with a chloride/bromide exchange process occurring in the first coordination sphere of an Au ion, UV−vis and electronic circular dichroism (ECD) spectra reveal the appearance of an induced dichroic signal attributable to Au complexes entrapped in the hydrophilic domain of the DMEB chiral nanostructures. Interestingly, change of the effective oxidation state and coordi…

Separation of presynaptic Cav2 and Cav1 channel function in synaptic vesicle exo- and endocytosis by the membrane anchored Ca2+ pump PMCA

2021

Significance Synaptic vesicle (SV) release from presynaptic terminals requires nanometer precise control of action potential (AP)–triggered calcium influx through voltage-gated calcium channels (VGCCs). SV recycling also depends on calcium signals, though in different spatiotemporal domains. Mechanisms for separate control of SV release and recycling by AP-triggered calcium influx remain elusive. Here, we demonstrate largely independent regulation of release and recycling by two different populations of VGCCs (Cav2, Cav1), identify Cav1 as one of potentially multiple calcium entry routes for endocytosis regulation, and show functional separation of simultaneous calcium signals in the nanome…
