Iain Michael Chambers, Location, Borders and Beyond. Thinking with Postcolonial Art

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..

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

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
