Confocal Endomicroscopy Shows Food-Associated Changes in the Intestinal Mucosa of Patients With Irritable Bowel Syndrome

2014

Background & Aims We investigated suspected food intolerances in patients with irritable bowel syndrome (IBS) using confocal laser endomicroscopy (CLE) for real-time visualization of structural/functional changes in the intestinal mucosa after food challenge. Patients with functional changes after food challenge (CLE+) were placed on personalized exclusion diets and followed up for long-term symptom relief. Methods Thirty-six IBS patients with suspected food intolerance and 10 patients with Barrett's esophagus (controls) without IBS symptoms were examined by CLE at University Hospital Schleswig-Holstein (Kiel, Germany). Diluted food antigens were administered directly to the duodenal mucosa…

Ein Mikro-Atemstromventil für spontan atmende narkotisierte Kleintiere - A Respiratory Micro-Valve for Spontaneously Breathing Anaesthetized Small An…

1994

For the accurate functional analysis of the gas exchange in the lungs or evaluation of artificial oxygen carriers in spontaneously breathing anaesthetized small animals, we developed a new respiratory micro-valve. The body of the valve is made of aluminium, and the flaps are made of silicone rubber. The maximum flow rate in a rat measured with a pneumotachograph and the micro-valve was an average of 19.9 ml/s during inspiration, and 17.8 ml/s during expiration. The pressure measured in the tracheal tube was -0.85 during inspiration, and +0.39 cm H2O during expiration; the end-expiratory pressure in the tube was zero. In two experiments with anaesthetised rats lasting 4-5 hours, ventilation,…

Theoretical Studies of the Electronic Spectra of Organic Molecules

1995

The complete active space (CAS) SCF method in conjunction with multiconfigurational second-order perturbation theory (CASPT2) has been used to study the electronic spectra of a large number of molecules. The wave functions and the transition properties are computed at the CASSCF level, while dynamic correlation contributions to the excitation energies are obtained through the perturbation treatment. The methods yield energies, which are accurate to at least 0.2 eV, except in a few cases, where the CASSCF reference function does not characterize the electronic state with sufficient accuracy. The applications comprise: the polyenes from ethene to octatetraene (cis- and trans-forms); a number …

Analysis of Early 20th century Chromatic Modal Music with the use of the Generative Theory of Tonal Music - Pitch Space and Prolongational issues in …

2009

The Generative Theory of Tonal Music in its original form (Lerdahl & Jackendoff 1983) applied to music belonging to the Western tonal idiom only. However, during the last decade, theoretical and analytical research has been conducted on its application on diatonic or chromatic modal music. More specifically, Lerdahl addresses chromatic pitch spaces in chapters 6 & 7 of his "Tonal Pitch Space" (2001) and conducts analyses of late 19th century and 20th century music, while Temperley (The Cognition of Basic Musical Structures, 2001) and Tsougras (Modal Pitch Space, 2003) explore mainly the diatonic modal space. The present paper aims to clarify the concepts of modal mixture, modal interchange,…

Muri e strade di Sicilia. Per una riflessione sull’arte urbana

2017

Attraverso l’analisi del libro Street Art in Sicilia. Guida ai luoghi e alle opere, l’articolo giunge a riflessioni più generali sul fenomeno della street art. Ne seguono considerazioni sulla città e sull’arte che mettono in luce il valore della street art quale oper-azione nello spazio con le relative implicazioni politiche, socio-antropologiche, architettoniche e semiotiche che ne spiegano la funzione e la funzionalità. La street art, vera e propria narrazione visuale, diventa dunque una cartina al tornasole in quanto è istantaneamente capace di captare, assorbire e riflettere visivamente la fenomenologia del contemporaneo. Through the analysis of the Street Art book in Sicily. Guide to p…

Infrastrutture e paesaggio nella "città in estensione"

2017

L’esperienza didattica e di ricerca presentata nel saggio prende le mosse dall’attivazione di un laboratorio di laurea magistrale in Progettazione Architettonica diretto dal prof. Palazzotto e sviluppato nell’ambito del corso di laurea in Architettura dell’omonimo Dipartimento presso l’Università degli Studi di Palermo. Il laboratorio ha visto la partecipazione complessiva di 11 laureandi, che hanno esitato le proprie tesi negli anni compresi tra il 2013 e il 2015. Il laboratorio di laurea, facendo propria l’idea di “città-campagna” avanzata da Giuseppe Samonà nel 1976 – che porta con sé un esplicito riferimento a identità formali e spaziali specifiche intese a conferire allʼambito della ca…

Multiscale variation in drought controlled historical forest fire activity in the boreal forests of eastern Fennoscandia

2017

Forest fires are a key disturbance in boreal forests, and characteristics of fire regimes are among the most important factors explaining the variation in forest structure and species composition. The occurrence of fire is connected with climate, but earlier, mostly local-scale studies in the northern European boreal forests have provided little insight into fire-climate relationship before the modern fire suppression period. Here, we compiled annually resolved fire history, temperature, and precipitation reconstructions from eastern Fennoscandia from the mid-16th century to the end of the 19th century, a period of strong human influence on fires. We used synchrony of fires over the network…

La double signification des clos monastiques sur la côte de Nuits (Bourgogne, France) : étude archéologique et historique du Clos de Vougeot et d'aut…

2011

International audience; Sur le coteau, depuis Dijon et jusqu'au nord de Chalon-sur-Saône, une mer de vigne s'étend sur une bande étroite de moins de 5 km de large et longue de près de 60 km. Malgré la monoculture viticole, l'espace est subdivisé en d'innombrables parcelles, elles-mêmes partagées entre autant de propriétaires. Ce morcellement du territoire se retrouve aussi dans tous les chemins, meurgers et murs qui délimitent des espaces, plus ou moins fermés et plus ou moins vastes, appelés climats . Dans ce contexte où la délimitation est omniprésente, les clos viticoles jouent un rôle important dans la structuration de l'espace alors que leur origine exacte reste assez floue...
