The significance of plasma kinins in intestinal obstruction and peritonitis
1969
The present concept of plasmakinin action suggests that they may also play an important role in the pathophysiology of intestinal obstruction and peritonitis. Since the assay of the kinins is still something of a problem, and since the percursor kallikrein can be determined by a standardized method, we studied the titers of kallikrein in the peripheral and portal circulation in dogs with experimental intestinal obstruction and in patients with these disorders. Significantly higher levels of kallikrein were found in intestinal obstruction, particularly in obstruction with strangulation (Fig. 1).
Collisional models in a nonperturbative approach
1992
Abstract A nonperturbative method set forth recently for handling quantum dynamics in the intermediate regime (far from either the sudden or the adiabatic limit) is applied to soluble two-state collisional models.
Pietro Novelli architetto. Disegni di portali e finestre
2013
Tra i disegni della collezione del barone Pietro Sgadari di Lo Monaco, oggi conservati presso la Galleria Interdisciplinare Regionale della Sicilia di Palazzo Abatellis (Palermo), figurano sette portali e una finestra attribuiti al noto pittore Pietro Novelli (1603 - 1647). I dettagli di alcuni portali - come quello di Santa Maria Maggiore nel quartiere Albergheria - richiamano le incisioni del secondo volume Della Trasportatione dell’obelisco vaticano… di Domenico Fontana (Napoli 1604); inoltre nel grafico S.L.M. Novelli 75 è possibile riconoscere il portale laterale di Santa Teresa alla Kalsa, in origine appartenente alla chiesa della Madonna delle Raccomandate, oggi non più esistente.
Activation of alpha-1A adrenoceptors mobilizes calcium from the intracellular stores in myocytes from rat portal vein.
1994
International audience; Intracellular free Ca++ concentration ([Ca++]i) was monitored using the fluorescence from the dye fura-2-acetoxymethylester in single myocytes from rat portal vein. In the presence of oxodipine (a L-type Ca++ channel inhibitor), norepinephrine (10 microM) evoked transient increases in [Ca++]i which were related to release of Ca++ from intracellular stores. The alpha-1 adrenoceptors mediating intracellular Ca++ release and inositol phosphate accumulation were identified by using subtype-selective agonists and antagonists. Pretreatment with chloroethylclonidine had little effect on the norepinephrine-induced increase in [Ca++]i and inositol phosphate accumulation. In c…
Il portale obliquo della cappella di Santa Lucia nel duomo
2013
Il contributo analizza uno dei due portali di accesso alla cappella di Santa Lucia nel duomo di Siracusa, caratterizzato da una geometria obliqua nel taglio delle imposte e nella conformazione dell'arco. L'elemento databile ai primi decenni del Settecento appare riconducibile tra l'altro alle soluzioni proposte dal trattato di Caramuel.
Il portale obliquo nel Palazzo Abatellis
2013
Il contributo analizza e commenta la presenza di un portalino obliquo, a imposte divergenti e non ortogonali alla giacitura del muro nel quale si inserisce, all'interno del quattrocentesco Palazzo Abatellis a Palermo. Interessante saggio di stereotomia moderna praticata in Sicilia a partire dal XV secolo sulla scorta di precedenti esperienze elaborate nel Levante iberico.
Porta et fenestra: frammenti di un libro del Seicento napoletano
2012
In spring 2011 some small engravings of immaginative portals appeared on the antiquarian market in Palermo, interesting traces of a bigger collection probably put together by an unknown Sicilian architect. Assembled with other portals coming from the book "Porte d'archittettura rustica...", by Orazio Perucci, these engravings make part for sure of another book -till now apparently unknown to the scholars - dedicaded to the same specific theme of "Porta et fenestra" (portals and windows), as can be drawn from a fragment of the title page. By the schape and the language, these portals can be easily dated to the seventeenth century, while the author can be identified in Bonaventura Presti (Bol…
A Methodological Approach for Developing and Validating a Parsimonious and Robust Measurement Tool: The Academic E-Service Quality (ACEQUAL) Model
2021
Nowadays, in the higher education sector, the quality measurement process of education-related services is assuming a crucial role to support focused and targeted improvement activities deeply centered on students’ needs/necessities. These are considered crucial factors for dealing with the current academic competitive context. Therefore, the quality measurement process has to be precise and accurate, namely the measurement model on which it is based has to be parsimonious and robust. The present work proposes an effective and easy-to-use methodological approach suitable for supporting the structuring of a measurement tool. Its effectiveness is shown with reference to the academic e-service…
Bilateral single-port thoracoscopic extended thymectomy for management of thymoma and myasthenia gravis: Case report
2016
Background Video-assisted thoracoscopy is become a widely accepted approach for the resection of anterior mediastinal masses, including thymoma. The current trend is to reduce the number of ports and minimize the length of incisions to further decrease postoperative pain, chest wall paresthesia, and length of hospitalization. Herein, we reported an extended resection of thymoma in a patient with myasthenia gravis through an uniportal bilateral thoracoscopic approach. Case presentation A 74 years old woman with myasthenia gravis was referred to our attention for management of a 3.5 cm, well capsulate, thymoma. All laboratory and cardio-pulmonary tests were within normal; thus, she was schedu…
Uniportal thoracoscopy combined with laparoscopy as minimally invasive treatment of esophageal cancer
2018
A 67-year-old man was referred to our attention for management of esophageal adenocarcinoma, localized at the level of the esophagogastric junction and obstructed the 1/3 of the esophageal lumen. Due to the extension of the disease (T3N1M0-Stage IIIA), the patient underwent neo-adjuvant chemo-radiation therapy and he was then scheduled for a minimally invasive surgical procedure including laparoscopic gastroplasty, uniportal thoracoscopic esophageal dissection and intrathoracic end-to-end esophago-gastric anastomosis. No intraoperative and post-operative complications were seen. The patient was discharged in post-operative day 9. Pathological study confirmed the diagnosis of adenocarcinoma …
