LESIONI ORALI E CERVICALI ASSOCIATE A PAPILLOMA VIRUS UMANO
2009
The aim of this review is to carry out a quick excursus on the epidemiological and clinical aspect of oral and cervical lesions induced by human papillomavirus (HPV) infection and on the way this virus is transmitted. HPV infection is transmitted above all through vaginal or anal sexual relations with partners carrying the virus. Also other types of sexual relations, such as oral sex, can be a vehicle of transmission, though much more rarely. In literature there is not enough data proving that oral-genital contact can really be a vehicle of transmission for human papillomavirus. It can be concluded, therefore, that evidences in further studies with a large sample group of patients who pract…
OCT e GDx VCC : nelle patologie papillari non glaucomatose
2009
L'autore presenta una serie di patologie papillari non glaucomatose, evidenziando come una non corretta appropriatezza degli esami strumentali, possa indurre ad errori diagnostici. La diagnosi, quindi, non deve essere lasciata interamente alle macchine ma deve essere sempre guidata dall'uomo.
Ubertino da Corleone
2020
Originario di Corleone, Ubertino era un francescano minore con una solida preparazione, abituato a interloquire con papi e re. La sua abilità oratoria fu apprezzata da Giovanni Boccaccio, che l’incontrò a Napoli. Studiò teologia a Londra, Oxford, Parigi, fu lettore a Pisa e Padova. Tornato in Sicilia, divenne cappellano regio e nel 1372 partecipò ai negoziati di pace tra Federico IV, re di Sicilia, e Giovanna I, regina di Napoli. Ad Avignone, incontrò Gregorio XI, che lo nominò vescovo di Corico, nel Regno di Cilicia. Fu poi vescovo di Patti e Lipari e nel 1396 si recò in Aragona per mediatore tra il papa romano Bonifacio IX e il papa avignonese Benedetto XIII. In seguito, divenne vescovo d…
Tetraspanin CD151 Mediates Papillomavirus Type 16 Endocytosis
2013
ABSTRACT Human papillomavirus type 16 (HPV16) is the primary etiologic agent for cervical cancer. The infectious entry of HPV16 into cells occurs via a so-far poorly characterized clathrin- and caveolin-independent endocytic pathway, which involves tetraspanin proteins and actin. In this study, we investigated the specific role of the tetraspanin CD151 in the early steps of HPV16 infection. We show that surface-bound HPV16 moves together with CD151 within the plane of the membrane before they cointernalize into endosomes. Depletion of endogenous CD151 did not affect binding of viral particles to cells but resulted in reduction of HPV16 endocytosis. HPV16 uptake is dependent on the C-termina…
TASTE RECEPTORS FOR GLUTAMATE IN HUMAN FUNGIFORM PAPILLAE

The Innervation of Taste Buds in the Soft Palate and Circumvallate Papilla of the Rat as Revealed by the Zinc Iodide-Osmium Tetroxide Technique.
1998
The taste buds in the soft palate and the circumvallate papillae of the rat were investigated by the zinc iodide-osmium tetroxide technique. In addition, electron micrographs of taste buds stained with this method were presented for the first time. Differences in taste bud structures were found between the examined regions. The taste buds of the soft palate showed a complicated plexus of intragemmal nerve fibers. Some fibers exhibited terminal polymorphic swellings. Single branches could be traced close to the space of the taste pore. In the soft palate, the taste bud cells remained unstained, whereas in the circumvallate papillae of the tongue, a subpopulation of taste bud cells could be s…
Sur la piste du « goût du gras »
2006
Sense of taste informs the body about the quality of ingested foods. Five sub-modalities allowing the perception of sweet, salty, sour, bitter, and umami stimuli are classically depicted in Human. However, the spontaneous attraction of mammals for fatty foods raises the possibility of an additional oro-sensory modality devoted to the fat perception. During a long time, oro-sensory perception of dietary lipids was thought to take place only through textural and retronasal olfactory cues. This minireview analyses recent findings showing that the gustation can also play a significant role in the dietary lipid perception.
Performance of Contrast-Enhanced Ultrasound in Thyroid Nodules: Review of Current State and Future Perspectives
2021
Simple Summary Ultrasound has been used as baseline imaging for thyroid nodules for decades; nevertheless, no single feature is sensitive or specific enough to exclude or confirm thyroid malignancy. Therefore, clinical practice and research still focus on less invasive diagnostic patterns to reduce unnecessary fine-needle aspiration biopsies or surgery. The main advantage of CEUS is the ability to assess the sequence and intensity of vascular perfusion and hemodynamics in the thyroid nodule, thus providing real-time characterization of nodule features, and considered a valuable new approach in the determination of benign vs. malignant nodules. In addition, contrast agents used in CEUS can h…
Extranodal extension in N1-adenocarcinoma of the pancreas and papilla of Vater: A systematic review and meta-analysis of its prognostic significance
2016
The aim of the study was to investigate the prognostic role of extranodal extension (ENE) of lymph node metastasis in adenocarcinoma of the pancreas (PDAC) and papilla [cancer of the papilla of Vater (CPV)]. A PubMed and SCOPUS search from database inception until 5 January 2015 without language restrictions was conducted. Eligible were prospective studies reporting data on prognostic parameters in individuals with PDAC and/or CPV, comparing participants with the presence of ENE (ENE +) with those with intranodal extension (ENE). Data were summarized using risk ratios for number of deaths/recurrences and hazard ratios for time-dependent risk related to ENE+, adjusted for potential confounde…
