ASPETTI BIO-TAFONOMICI IN AMBIENTE CARSICO COME INDICATORI DEL RITO DEL MEGARIZEIN
2015
Il culto di Demetra e Kore era uno tra i più diffusi del mondo antico di cultura greca. Tuttavia, a causa della sua forte componente misterica, le modalità secondo le quali si articolavano alcuni riti ad esso connessi rimangono poco chiare e le fonti storiche ci forniscono poche e incerte informazioni in merito. Uno dei riti chiave avveniva durante le Tesmoforie, le principali feste in onore di Demetra e Kore, e consisteva nel rito del Megarizein. Il rituale prevedeva che dei maialini venissero gettati all’interno di cavità ipogee (megara) e che successivamente venissero recuperate le loro carcasse decomposte da offrire alle divinità. Qui presentiamo i risultati preliminari di un esperiment…
The inconspicuous penis in children
2015
The term 'inconspicuous penis' refers to a group of anatomical abnormalities in which the penis looks smaller than is expected. Micropenis can be defined as 'true micropenis' - which results from a defect in the hypothalamic-pituitary-gonadal axis - and 'micropenis secondary to congenital anatomical anomalies of the surrounding and overlying structures' - also known as 'concealed penis'. The different forms of concealed penis include webbed penis, congenital megaprepuce and partially hidden penis caused by prepubic adiposity. This disorder can also have iatrogenic causes resulting from adhesions that are secondary to circumcision - this type of concealed penis is known as 'trapped penis'. H…
Modular megaprosthesis reconstruction for oncological and non-oncological resection of the elbow joint
2016
Abstract Background Reconstruction of large bone defects around the elbow joint is surgically demanding due to sparse soft tissue coverage, complex biomechanics and the close proximity to neurovascular structures. Modular megaprostheses are established reconstruction tools for the elbow, but only small case series have been reported in the literature. Methods Thirty-six patients who underwent reconstruction of the elbow joint with a modular megaprosthesis were reviewed retrospectively. In 31 patients (86.1%), elbow replacement was performed after resection of a bone tumour, whereas five non-oncological patients (13.9%) underwent surgery because of a previous failed elbow reconstruction. Fun…
Il mare e la città. Cefalù e il Parco delle mura megalitiche di Pasquale Culotta, Giuseppe Leone e Tania Culotta.
2019
Il Mediterraneo è una delle fonti dell’architettura tout court ed è all’origine della storia dell’abitare del Vecchio Mondo. Al ruolo costante e di fondazione del Mare Nostrum si collega, diversi millenni dopo, quello avuto come impulso all’architettura contemporanea e, in particolare, al Movimento Moderno. Su tale imprescindibile rapporto si innesta una specifica questione relativa alle città costiere e al modo in cui queste abbiano concretamente declinato l’interazione con il mare. Se l’arco cronologico si restringe dal secondo dopoguerra ad oggi, molti di questi rapporti sono occasioni mancate, incontri distratti, dove le coste, al pari dei fondi agricoli, sono state considerate, in modo…
Double-J stent insertion across vesicoureteral junction--is it a valuable initial approach in neonates and infants with severe primary nonrefluxing m…
2006
Abstract Objectives To evaluate the role of double- J stent insertion in perinatally detected primary nonrefluxing megaureters as a method to temporize treatment in patients with impaired renal function or to prevent function loss in patients treated expectantly, but deemed at high risk of deterioration. Methods Two neonates and 8 infants with a ureter greater than 10 mm and an obstructive excretion pattern, including 3 cases with renal function less than 40%, were selected to undergo double- J stent insertion for a 6-month period. Patients underwent surgery if the ureter redilated and the excretion pattern was obstructive at reassessment 3 months after stent removal. Results Stents were pl…
Transient Radiation Responses of Optical Fibers: Influence of MCVD Process Parameters
2012
International audience; A dedicated set of fibers elaborated via the Modified Chemical Vapor Deposition (MCVD) technique is used to study the influence of composition and drawing parameters on their responses to an X-ray pulse representative of the radiation environments associated with Megajoule class lasers. These canonical fibers were designed to highlight the impact of these parameters on the amplitude and kinetics of the transient pulsed X-ray Radiation Induced Attenuation (RIA) at room temperature. From preforms differing by their core composition, three optical fibers were elaborated by varying the tension and speed during the drawing process. No or only slight RIA change results fro…
Olympic Games and Their Impacts

The modern Olympic Games is considered by many to be the world’s greatest sport festival. Economic, Sociocultural and Environmental impacts are described along with policy implications, from both an historical and current perspective.
The transcriptional activator rfiA is quorum-sensing regulated by cotranscription with the luxI homolog pcol and is essential for plant virulence in …
2009
The gram-negative phytopathogen Pseudomonas corrugata has an acyl-homoserine lactone (AHL) quorum-sensing (QS) system called PcoI/PcoR that is involved in virulence on tomato. This work identifies, downstream of pcol, a gene designated rfiA, which we demonstrate is directly linked to QS by cotranscription with pcol. The deduced RfiA protein contains a DNA-binding domain characteristic of the LuxR family but lacks the autoinducer-binding terminus characteristic of the QS LuxR-family proteins. We also identified, downstream of rfiA, an operon designated pcoABC, encoding for the three components of a tripartite resistance nodulation-cell-division (RND) transporter system. The expression of pco…
Surgical Emergencies in Crohn’s Disease
2015
Crohn’s disease, as a chronic inflammatory disease of unknown etiology that can affect any part of the alimentary canal from the mouth to the anus, has a highly variable course and a very unpredictable evolution. Even surgery does not cure CD, it has however a relevant role in its treatment in combination to medical therapy during the large course of the disease; indeed almost each patient is submitted to a surgical intervention during his life. Nowadays, surgery is considered the last treatment to use whenever medical therapy is insufficient to control symptoms; this choice involves an intervention on more serious patients with more surgical complications. Surgery finds in the Crohn’s dise…
