Salmeterol Xinafoate (SX) loaded into mucoadhesive solid lipid microparticles for COPD treatment

2019

Chronic obstructive pulmonary disease (COPD) is one of the main health problems worldwide. It is characterised by chronic inflammation in the lungs that leads to progressive, chronic, largely irreversible airflow obstruction. The use of long-acting β agonists remain today the frontline treatment for COPD with the aim of minimizing side effects and enhancing therapeutic usefulness. To this purpose, in this paper, mucoadhesive solid lipid microparticles (SLMs) containing a long-acting β-2 agonist, Salmeterol Xinafoate (SX) were prepared, characterised (size, z-potential, aerodynamic diameter, turbidimetric evaluations, drug loading and entrapping efficiency) and tested in a model of bronchial…

Optimization design process of a morphing winglet

2018

Aeronautic and aerospace engineering is recently moving in the direction of developing morphing wing devices, with the aim of making adaptable the aerodynamic shapes to different operational conditions. Those devices may be classified according to two different conceptual architectures: kinematic or compliant systems. Both of them embed within their body all the active components (actuators and sensors), necessary to their operations. In the first case, the geometry variation is achieved through an augmented classical mechanism, while in the second case the form modification is due to a special arrangement of the inner structure creating a distributed elastic hinges arrangement. Whatever is…

‘La chiamiamo con entrambi i nomi’: eponimia ed eteronimia tra Nemesis e Adrasteia

2020

Prendendo le mosse da un passo di Ammiano Marcellino (XIV 11,25), che lascia emergere un’evidente sovrapposizione tra la figura di Adrasteia e quella Nemesis, il contributo si propone di esaminare le ragioni che hanno condotto le due potenze ad essere indicate l’una come l’eteronimo dell’altra. A partire dalle fonti di V secolo fino alla paremiografia e alla lessicografia di età imperiale si ricostruisce un percorso che si propone di mostrare gli accidenti e le molteplici variabili cui le logiche di denominazione del divino, nel mondo greco, possono essere soggette. Starting from a passage by Ammiano Marcellino (XIV 11,25), which reveals an evident overlap between the figure of Adrasteia an…

Mesenchymal stem cells of Systemic Sclerosis patients, derived from different sources, show a profibrotic microRNA profiling

2019

AbstractSystemic Sclerosis (SSc) is a disease with limited therapeutic possibilities. Mesenchymal stem cells (MSCs)-therapy could be a promising therapeutic option, however the ideal MSCs source has not yet been found. To address this problem, we perform comparison between bone marrow (BM)-MSCs and adipose (A)-MSCs, by the miRs expression profile, to identify the gene modulation in these two MSCs source. MicroRNAs (miRs) are RNAs sequences, regulating gene expression and MSCs, derived from different tissues, may differently respond to the SSc microenvironment. The miRs array was used for the miRs profiling and by DIANA-mirPath tool we identified the biological functions of the dysregulated …

Interleukin-9 over-expression and T helper 9 polarization in systemic sclerosis patients.

2017

Summary T helper 9 (Th9) cells and interleukin (IL)-9 are involved in the pathogenesis of several autoimmune diseases. The exact role of IL-9 and Th9 cells in patients with systemic sclerosis (SSc) have not yet been studied adequately. IL-9, IL-9R, transcription factor PU.1 (PU.1), IL-4, thymic stromal lymphopoietin (TSLP) and transforming growth factor (TGF)-β expression were assessed in skin and kidney biopsies of SSc patients and healthy controls (HC) by immunohistochemistry (IHC). The cellular source of IL-9 was also analysed by confocal microscopy analysis. Peripheral IL-9-producing cells were also studied by flow cytometry. The functional relevance of IL-9 increased expression in SSc …

HRCT and scleroderma: semiquantitative evaluation of lung damage and functional abnormalities.

2007

This study sought to validate the Warrick score in the assessment of lung involvement in systemic sclerosis (SSc) and correlate the results with functional abnormalities. In addition, we propose the use of high resolution computed tomography (HRCT) indices of alveolitis and fibrosis to discriminate between different stages of the disease.Thirty-one patients with SSc (16 with the diffuse form and 15 with the limited form) underwent functional and HRCT evaluations of the lung. The semiquantitative evaluation of radiological involvement, as proposed by Warrick, provides a score for each lesion based on the severity and the extent of the pulmonary damage. In addition to the total score, indices…

Population attributable risk of tobacco and alcohol for upper aerodigestive tract cancer.

2011

Tobacco and alcohol are major risk factors for upper aerodigestive tract (UADT) cancer and significant variation is observed in UADT cancer rates across Europe. We have estimated the proportion of UADT cancer burden explained by tobacco and alcohol and how this varies with the incidence rates across Europe, cancer sub-site, gender and age. This should help estimate the minimum residual burden of other risk factors to UADT cancer, including human papillomavirus. We analysed 1981 UADT cancer cases and 1993 controls from the ARCAGE multicentre study. We estimated the population attributable risk (PAR) of tobacco alone, alcohol alone and their joint effect. Tobacco and alcohol together explaine…

Quantitative DNA measurements in malignant and benign lesions of the upper aerodigestive tract.

1992

Thirty-six patients underwent biopsy of clinically suspicious lesions of the mucosa of the upper aerodigestive tract. The biopsy material was evaluated histologically and cytologic smears out of the same lesion underwent quantitative DNA analysis using a numerical index derived from the single cell DNA content. In 30 patients, histologically diagnosed squamous cell cancer was confirmed by DNA analysis with the malignancy grade correlating with the morphologic differentiation of the tumor. Six lesions were histologically benign: i.e. dysplasia (n = 3), hyperplasia (n = 2) and chronic inflammation (n = 1). DNA analysis confirmed the benign nature in 4 cases, but in 2 cases of dysplasia, a dia…
