Altri cibi. Il packaging degli alimenti veg
2017
Il tema di questo contributo riguarda il packaging dei prodotti vegani e vegetariani nel mercato italiano della distribuzione organizzata. La scelta degli ambiti del packaging della gdo e del vegetarianismo ha a che fare con le attuali tendenze dietetiche che, come spesso accade con le scelte e le mode alimentari, mentre si diffondono massivamente si intrecciano tra di loro. Se, infatti, in linea di principio l’astensione dal mangiare carne è il passaggio giusto e inevitabile per portare avanti coerentemente gli interessi degli esseri animali, ed è dunque espressione di una presa di posizione etico-politica animalista, è vero che cibi vegani e vegetariani sempre più spesso entrano a far par…
Semiotic Roadmap for Designing Packaging
2015
This paper concerns the main aspects of semiotics of packaging. Packaging has to be considered as a special communicative touchpoint between brands and consumers, since it is a syncretic object (using various languages) with textures, materials, shapes and colours that consumers can see, touch, smell, involving different modes (visual, verbal, tactile) that convey a brand's core values.
Nature in vendita. Il packaging dei prodotti biologici
2012
Questo contributo indaga il funzionamento semiotico del packaging dei prodotti del mercato biologico. Tanti prodotti, tante marche, tanti pack che hanno in comune la naturalità come fi lo conduttore, una massa eteroclita che dice e ri-dice sempre lo stesso concetto di fondo. Ma come lo mette in forma? Quali sostanze specifi che vengono prodotte a livello del contenuto? E quali soggettività vengono delineate dal punto di vista narrativo ed enunciativo? Quali tipi di consumatori? Qui mi concentrerò su alcuni packaging alimentari, come confezioni per pasta, biscotti e altri prodotti di uso comune, prendendo in considerazione alcune delle marche più diffuse nei negozi specializzati bio.
Bcl-xL as a Modulator of Senescence and Aging
2021
Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…
Microchimerism in multiple sclerosis: The association between sex of offspring and MRI features in women with multiple sclerosis
2023
AimsDuring pregnancy, fetal cells can migrate to the mother via blood circulation. A percentage of these cells survive in maternal tissues for decades generating a population of fetal microchimeric cells (fMCs), whose biological role is unclear. The aim of this study was to investigate the association between the sex of offspring, an indirect marker of fMCs, and magnetic resonance imaging (MRI) features in women with multiple sclerosis (MS).MethodsWe recruited 26 nulliparous MS patients (NPp), 20 patients with at least one male son (XYp), and 8 patients with only daughters (XXp). Each patient underwent brain MR scan to acquire 3D-T2w FLAIR FatSat and 3D-T1w FSPGR/TFE. Lesion Segmentation To…
Microchimerism and multiple sclerosis: a study on the impact of the sex of offspring on clinical, radiological, and paraclinical features of maternal…
2023
Background. Multiple sclerosis (MS) is a chronic autoimmune disorder characterised by inflammation and neurodegeneration and representing one of the most common causes of neurologic disability among young adults. Over the last 40 years, several authors have confirmed the existence of fetal cells in maternal blood and their pregnancy-related origin, demonstrating that pregnancy may establish a long-term, low-grade chimeric state in women. The biological and clinical significance of fetal microchimeric cells (fMCs) in maternal health is largely unknown, although a role in autoimmune diseases have been hypothesised. Aims. The overarching aim of my PhD dissertation was to investigate the role o…

A Shape-based Statistical Method to Retrieve 2D TRUS-MR Slice Correspondence for Prostate Biopsy
2012
International audience; This paper presents a method based on shape-context and statistical measures to match interventional 2D Trans Rectal Ultrasound (TRUS) slice during prostate biopsy to a 2D Magnetic Resonance (MR) slice of a pre-acquired prostate volume. Accurate biopsy tissue sampling requires translation of the MR slice information on the TRUS guided biopsy slice. However, this translation or fusion requires the knowledge of the spatial position of the TRUS slice and this is only possible with the use of an electro-magnetic (EM) tracker attached to the TRUS probe. Since, the use of EM tracker is not common in clinical practice and 3D TRUS is not used during biopsy, we propose to per…
Influence of Degradative Enzymatic Activities on the Shelf Life of Ready-to-Eat Prickly Pear Fruits
2012
Prickly pear fruit (Opuntia ficus indica L. Miller) belongs to the Cactaceae family. This species is very sensitive to low storage temperatures (< 5°C) which cause damages. The fruits can be peeled, suitably packaged and successfully commercialized as a ready-to-eat product. The main limit to the extension of the shelf life is the production of off-flavors due to different factors, the growth of microorganisms and the action of endogenous enzymes. Lipoxygenase (LOX) and Pectinesterase (PE) are involved in fruit degradation. In particular, LOX pathway is directly responsible for lipid oxidation, and the subsequent production of off-flavours, while PE causes the softening of fruit during m…
