Role of a medication in polyurethane foam in the treatment of diabetic foot lesions
2010
Background The treatment of diabetic foot lesions need medications capable of managing wound infection and exudates that, variously combined, can influence the natural history of the pathology and therefore limb survival. A particular and economic device, is represented by honeycomb structure polyurethane foam Ligasano ©.
Cartelization process in institutionalized environments: legitimation and political communication
2017
International audience; The main objective of this paper is to analyze cartel party tendencies toward professionalization of communicative institutional processes (Mair, 015).The main role of the media in a audience democracy is indisputable (Manin, 1998). So the media politics are one of the main features of public space. In this way, Political parties have become platforms of placement of their leaders to occupy the largest number of institutional positions. Consequently, this phenomenon has spread as a common practice of our political system. The emergence of partisan elite, which has professionalized itself in high political-institutional positions, has colonized the leadership of publi…
Vascular Patterns in Dermoscopy
2012
Under the right conditions, dermoscopy allows us to observe the vascular features of many different types of skin lesions. The visualization and identification of vessels with a characteristic morphology can be the key to diagnosis, especially in hypopigmented lesions in which the typical pigmented structures are not visible. Some of the more characteristic associations are the presence of crown vessels in sebaceous hyperplasia, arborizing telangiectasias in basal cell carcinoma, comma-shaped vessels in intra- dermal and compound nevi, dotted vessels in Spitz nevi and melanoma, and hairpin vessels in seborrheic keratoses. The recognition of distinctive vascular features can be of great help…
The Italian validation of the Montreal Global definition and classification of gastroesophageal reflux disease
2009
Recently, a Global definition and a classification of gastroesophageal reflux disease (GERD) were developed by Montreal Consensus Group, composed of international expert gastroenterologists. Guidelines and consensus documents are, however, infrequently accepted and adopted at a local level. The aim of this study was to measure the acceptance of Montreal Global definition of GERD consensus document by specialists in a single country (Italy) and to measure the linguistic, scientific, and practical differences between the international consensus document and the Italian version.A 2-day meeting was held in June 2007 in Rome, Italy, attended by 147 Italian physicians who were experts in gastroen…
Chloracne after release of TCDD at Seveso, Italy
1981
ABSTRACT The paper deals with clinical and epidemiological findings concerning persons showing skin lesions after release of TCDD at Seveso. A positive association was observed between geographical distribution of cases and levels of soil contamination. Gastro-intestinal tract impairments were more frequently observed in children with chloracne than in children from the same areas showing no skin lesions. To date, no major immunological involvement has been observed in samples of children exposed to TCDD.
Excimer laser technology in percutaneous coronary interventions: Cardiovascular laser society's position paper
2022
Excimer Laser Coronary Atherectomy (ELCA) is a well-established therapy that emerged for the treatment of peripheral vascular atherosclerosis in the late 1980s, at a time when catheters and materials were rudimentary and associated with the most serious complications. Refinements in catheter technology and the introduction of improved laser techniques have led to their effective use for the treatment of a wide spectrum of complex coronary lesions, such as thrombotic lesions, severe calcific lesions, non-crossable or non-expandable lesions, chronic occlusions, and stent under-expansion. The gradual introduction of high-energy strategies combined with the contrast infusion technique has enabl…
Forever Young: Structural Stability of Telomeric Guanine Quadruplexes in the Presence of Oxidative DNA Lesions**
2021
International audience; Human telomeric DNA, in G-quadruplex (G4) conformation, is characterized by a remarkable structural stability that confers it the capacity to resist to oxidative stress producing one or even clustered 8-oxoguanine (8oxoG) lesions. We present a combined experimental/computational investigation, by using circular dichroism in aqueous solutions, cellular immunofluorescence assays and molecular dynamics simulations, that identifies the crucial role of the stability of G4s to oxidative lesions, related also to their biological role as inhibitors of telomerase, an enzyme overexpressed in most cancers associated to oxidative stress.
The identity type weak factorisation system
2008
We show that the classifying category C(T) of a dependent type theory T with axioms for identity types admits a non-trivial weak factorisation system. We provide an explicit characterisation of the elements of both the left class and the right class of the weak factorisation system. This characterisation is applied to relate identity types and the homotopy theory of groupoids.
The socio-ecological and personal determinants of school performance and motivation of high school students
2022
For decades, and with the work of Moos (1979) and Walberg (1969), educational research has consistently demonstrated the importance of the personal characteristics of students and the socio-ecological characteristics of the classroom in determining the affective and cognitive development of students.Unfortunately, no research on this subject has been done in France with high school students. This is why we set ourselves the objective of studying the environmental and personal determinants of high school students' academic performance and motivation. Using the L.E.I (Walberg, 1969) and EMMAS (Ntamakiliro et al., 2000) measurement scales, as well as data collection from 405 students enrolled …
