Chitosan Film Functionalized with Grape Seed Oil—Preliminary Evaluation of Antimicrobial Activity

2022

Although the fishing and wine industries undoubtedly contribute significantly to the economy, they also generate large waste streams with considerable repercussions on both economic and environmental levels. Scientific literature has shown products can be extracted from these streams which have properties of interest to the cosmetics, pharmaceutical and food industries. Antimicrobial activity is undoubtedly among the most interesting of these properties, and particularly useful in the production of food packaging to increase the shelf life of food products. In this study, film for food packaging was produced for the first time using chitosan extracted from the exoskeletons of red shrimp (Ar…

Neutrophil extracellular traps arm DC vaccination against NPM-mutant myeloproliferation

2022

Neutrophil extracellular traps (NETs) are web-like chromatin structures composed by dsDNA and histones, decorated with antimicrobial proteins. Their interaction with dendritic cells (DCs) allows DC activation and maturation toward presentation of NET-associated antigens. Differently from other types of cell death that imply protein denaturation, NETosis preserves the proteins localized onto the DNA threads for proper enzymatic activity and conformational status, including immunogenic epitopes. Besides neutrophils, leukemic cells can release extracellular traps displaying leukemia-associated antigens, prototypically mutant nucleophosmin (NPMc+) that upon mutation translocates from nucleolus …

Recupero e consolidamento della collezione scheletrica del Museo di Zoologia “Doderlein”

2019

Il presente articolo illustra un’operazione di restauro che ha aperto una fase di recupero di diversi elementi scheletrici, da tempo deteriorati, nel Museo di Zoologia “Doderlein”, oggi afferente al Sistema Museale d’Ateneo - SIMUA - dell’Università degli Studi di Palermo. Il lavoro si è articolato in pulitura, restauro e consolidamento di cinquanta pezzi dei cinque gruppi di vertebrati. Questo intervento rappresenta solamente una piccola tessera di un progetto più ampio, che ha come obiettivo finale il recupero dell’intera collezione zoologica presente in Museo. The present work took place in the Museum of Zoology “Doderlein” of the SIMUA, University of Palermo. A restoration of skeletons …

Museomics Provides Insights into Conservation and Education:The Instance of an African Lion Specimen from the Museum of Zoology “Pietro Doderlein”

2023

Innovative technological approaches are crucial to enhance naturalistic museum collections and develop information repositories of relevant interest to science, such as threatened animal taxa. In this context, museomics is an emerging discipline that provides a novel approach to the enhancement and exploitation of these collections. In the present study, the discovery of a neglected lion skeleton in the Museum of Zoology “Pietro Doderlein” of the University of Palermo (Italy) offered the opportunity to undertake a multidisciplinary project. The aims of the study consisted of the following: (i) adding useful information for museographic strategies, (ii) obtaining a new genetic data repositor…

Effects of conjugated linoleic acid and endurance training on peripheral blood and bone marrow of trained mice

2007

Fat supplements, es- pecially conjugated linoleic acid (CLA), are increasingly popular ergogenic aids among endurance athletes. To evaluate the im- portance of fat supplementation in the practice of endurance sports, we investigated the effects of CLA supplementation on body weight, muscle hypertrophy, peripheral blood composition, and bone marrow composition in healthy, young, endurance- trained mice. Young, healthy mice were subdivided into control, trained, and treated groups, according to their running atti- tudes. Training was performed over a period of 6 weeks on a treadmill, at a gradually increasing duration and speed. CLA- treated groups were gavaged with 0.425 mg·d 1 CLA supplemen…

Role of Th cytokines in thyroid autoimmunity

2007

Thyroid autoimmunity occurs when the immune system reacts against thyroid cells after targeting them like any other “not-self” antigen. To define a thyroid autoimmune disorder is often difficult even if the presence of auto-antibodies and/or autoreactive lymphocytes is a common feature. Although the pathogenetic mechanism is poorly understood, increasing evidences indicate that apoptosis is one of the key process that leads to thyroid auto-immunity. Afterward, Th cytokines have been considered the regulator factors of the cell survival in thyroid autoimmunity. Understanding the cell response from the perspective of type 1 or type 2 cytokines could clarify the pathogenetic mechanism controll…

MESENCHIMAL STEM CELLS IN INFLAMMATORY BOWEL DISEASES: CLINICAL EVIDENCES AND POTENTIAL INSIGHTS FOR THE CLINICIANS

2013

Mesenchimal stem cells (MSCs) have been used experimentally and clinically in the treatment of a wide variety of pathologies MSCs can be safely transplanted in autologous and allogenic ways as they are non-immunogenic, and consequently represent a therapeutic option for refractory connective tissue diseases, fibrosing diseases like scleroderma and fistulizing colitis like in Crohn's disease (CD). The immunomodulatory properties of MSCs have already shown promise when used as therapy for otherwise medically refractory CD. Accumulating evidence suggests that the properties may also be exploited of several other conditions. The currently available experimental and clinical data indicate that, …

CAN THE AORTIC WALL COMMUNICATE WITH US?

2014

OBJECTIVE: Association between aortic aneurysm wall and risk of rupture or dissection. METHODS: Aortic specimens were obtained from 73 patients (51 men and 22 women, whose median age 61.7± 10.7 years) undergoing surgical repair of thoracic ascending aneurysm (TAA). Histopathological and immunohistochemical analyses were performed using adequate tissue specimens, appropriate techniques and criteria. Furthermore, genetic risk factors were also investigated. RESULTS: We identified three phenotypes of TAAs with different quality of aortic wall at the time of operation: phenotype I (normal wall); phenotype II (moderate wall thickness); phenotype III (thin and weak wall). No significant differenc…
