    È a partire da un ragionamento critico con l’arte che è possibile andare oltre l’inganno della rappresentazione come mimesi della realtà oggettiva e proporre un “evento etico”. Ed è l’arte postcoloniale quella in grado di interrompere, tagliare e riassemblare la cronologia, la geografia, la teleologia occidentale del progresso, la Storia e la storiografia ufficiale. Un’arte “inquietante”, che disturba le certezze del mondo moderno e spinge lo sguardo oltre i confini dell’eredità coloniale, di..

    Esercizi decoloniali: il contributo di una pratica curatoriale situata

    This paper chronichles a curatorial experience based in Naples: the intercultural workshop of urban photography entitled Crossing Sights, started in November 2019 and still active. Rather than analysing the phases of the laboratory in a punctual and exhaustive fashion, the paper aims at commenting on the criticalities, limits and possibilities I have detected as a co-curator. My “enunciation” is situated in the interiority of an unperfect West (Cazzato 2019) and it employs the concept of curating as a practice of hospitality. In addition, it argues that the “decolonial curating” is an anti-racist practice of “listening” (Bayer, Kazeem-Kamiński, Sternfeld 2018) that is open to the "epistemic diversity" and to the "pluriversality" (Mignolo Tlostanova 2006).The premise of my investigation is that we need to move beyond decolonization, towards "decolonialisation" (Borghi 2020). Born into the modern-western thought, curating can reply to this call by proposing itself as an exercise of deconstruction of "whiteness". The goal of curating should be to consider art as something different from modernist notions; therefore trying to work curatorially means to activate such work in terms of contents, opening the colonial archives, epistemics "de-linking" from modernity and “epistemic disobedience”, and ethics, positioning oneself and practicing self-critique. Central to the investigation is the main theme of Crossing Sights: "Neapolitanity", a label which serves the predatory objectives of capitalism and globalization. A trap that the laboratory has tried to criticize by adopting/embracing/employing the point of view of "others", and by shifting the attention from aesthetics to "aesthesis" (Mignolo 2019). Finally, while commenting on the strategy adopted in order to overcome the "coloniality", I suggest curating as a decolonial exercise generating gestures of anti-racist hospitality, that may help to think decolonially

    Scion–rootstock interactions influence the growth and behaviour of the grapevine root system in a heavy clay soil

    Background and Aims Generally, grapevine roots have been less studied than the above‐ground parts of the plant. Here we analyse scion–rootstock interactions in mature vines growing in a heavy clay soil in a climate characterised by severe summer drought to investigate the effect of the scion–rootstock interaction in a suboptimal soil. Methods and Results The rootstocks, 34 Ecole de Montpellier, 140 Ruggeri and 1103 Paulsen, were grafted onto Nerello Mascalese and Nero d'Avola scions and assessed along with self‐rooted vines. Root distribution and root architecture were analysed using the profile wall method at 0, 60 and 120 cm from the row midline. Root density was greatest at a depth between 21 and 60 cm. The cumulative root fraction for root density registered a β value, a numerical quantity that summarises depth distribution, ranging between 0.932 and 0.962. Root number and density were significantly lower for the self‐rooted vines compared to that of the grafted vines. Conclusions The scion genotypes affected most developmental parameters, including the diameter of the root system, the root density at 21–80 cm depth and the ratio of fine roots to coarse roots. Significance of the Study The scion plays an important role in grapevine root growth, development and distribution in a heavy clay soil, although the mechanism remains unclear

    Prognostic factors in laryngeal squamous cell carcinoma

    BackgroundThe current treatment results of laryngeal squamous cell carcinoma still remain modest. Various prognostic factors have been investigated and need to be included in the management decision making.MethodsWe reviewed the pertinent literature regarding host, tumor, and treatment factors as prognostic indicators that influence outcome in patients diagnosed with laryngeal squamous cell carcinoma.ResultsHost, tumor, and treatment factors all have an important impact upon an individual patient’s prognosis with laryngeal squamous cell carcinoma, whereas staging systems only take into account tumor factors. There is much work yet to be done to establish reliable, independent biomarkers that predict survival and response to treatment.ConclusionsOptimal outcomes for an individual patient can be achieved when taking into account tumor, host, and treatment factors.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154535/1/lio2353.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154535/2/lio2353_am.pd

    Analysis of the clinical relevance of histological classification of benign epithelial salivary gland tumours

    Get PDF
    IntroductionA vast increase in knowledge of numerous aspects of malignant salivary gland tumours has emerged during the last decade and, forseveral reasons, thishas not been the case in benign epithelial salivary gland tumours. We have performed a literature review to investigate whether an accurate histological diagnosis of the 11 different types of benign epithelial salivary gland tumours is correlated to any differences in their clinical behaviour.MethodsA search was performed for histological classifications, recurrence rates and risks for malignant transformation, treatment modalities, and prognosis of these tumours. The search was performed primarily through PubMed, Google Scholar, and all versions of WHO classifications since 1972, as well as numerous textbooks on salivary gland tumours/head and neck/pathology/oncology. A large number of archival salivary tumours were also reviewed histologically.ResultsPleomorphic adenomas carry a considerable risk (5-15%) for malignant transformation but, albeit to a much lesser degree, so do basal cell adenomas and Warthin tumours, while the other eight types virtually never develop into malignancy. Pleomorphic adenoma has a rather high risk for recurrence while recurrence occurs only occasionally in sialadenoma papilliferum, oncocytoma, canalicular adenoma, myoepithelioma and the membranous type of basal cell adenoma. Papillomas, lymphadenoma, sebaceous adenoma, cystadenoma, basal cell adenoma (solid, trabecular and tubular subtypes) very rarely, if ever, recur.ConclusionsA correct histopathological diagnosis of these tumours is necessary due to (1) preventing confusion with malignant salivary gland tumours; (2) only one (pleomorphic adenoma) has a considerable risk for malignant transformation, but all four histological types ofbasal cell adenoma canoccasionally develop into malignancy, as does Warthin tumour; (3) sialadenoma papilliferum, oncocytoma, canalicular adenoma, myoepithelioma and Warthin tumour only occasionally recur; while (4) intraductal and inverted papilloma, lymphadenoma, sebaceous adenoma, cystadenoma, basal cell adenoma (apart from the membranous type) virtually never recur. No biomarker was found to be relevant for predicting recurrence or potential malignant development. Guidelines for appropriate treatment strategies are given.info:eu-repo/semantics/publishedVersio

    Management of extracranial arteriovenous malformations of the head and neck

    The purpose of this study was to review the outcomes of the different therapies for extracranial head and neck arteriovenous malformations (AVMs). AVMs are high-flow congenital vascular anomalies. They are composed of a complex system of vessels directly connecting feeding arteries to draining veins forming a nidus. They may be potentially life-threatening due to progressive symptoms and infiltrative disease. Extracranial AVMs most commonly affect the head and neck area (47.4%) followed by the extremities (28.5%). AVMs are best characterized as being either focal or diffuse. Focal AVMs have good outcomes following adequate treatment. Diffuse lesions have multiple feeding vessel, which results in high rates of recurrence despite treatment. The management of AVMs includes conventional surgery and endovascular techniques. A combination of embolization and surgical resection has become the treatment of choice over the last years. The main goal of both forms of treatment being the complete blockage or resection of the nidus. Transcatheter embolization of vessels has evolved over the years and new embolic agents have emerged. The types of materials available for embolization are classified into mechanical devices, liquid agents and particulates. Efficacy, rate of recurrence and most common complications were evaluated. AVMs recurrence after embolization or resection is reported in up to 80% of cases. Incomplete resection and embolization can induce aggressive growth of the remaining nidus and the risk of progression is up to 50% within the first 5 years and recurrences can occur up to 10 years later. Although ethanol seems to be associated with the highest degree of cure and permanent occlusion, the overall complication rate reported was 48%. Other materials, such as cyanoacrylate, have obtained modest rates of complete remission, while the reported rates of complete regression of AVMs with Fibrin glue and Polyvinyl alcohol are above 50%. At present, there are no unified agreement on the ideal embolic agent. Therefore, a multidisciplinary approach is recommended to support decision making about the best therapeutic approach and to achieve optimal outcome. A long-term post-treatment follow-up is recommended to recognize early recurrence.Peer reviewe
