Utilidad de la ecografía endoanal tridimensional para el manejo y el diagnóstico de las fístulas perianales
2014
Las fístulas perianales afectan alrededor de 10/100000 personas/años con un pico de incidencia entre la tercera y la quinta década de la vida. Las fístulas y los abscesos perianales representan estadios sucesivos de una misma enfermedad supurativa, siendo entre el 80-90% de origen criptoglandular. La clasificación de las fístulas perianales no siempre resulta sencilla. La más utilizada y conocida es la clasificación de Parks, la cual divide las fístulas en: interesfintéricas, transesfintéricas, supraesfintéricas y extraesfintéricas. Otras formas clásicas de clasificar las fístulas es en: simples y complejas (según la dificultad a la hora del manejo) o altas y bajas (según la altura a la que…
Periodontal health in a population with Parkinson's disease in Spain: a cross-sectional study.
2022
Background: The aim of this research is to evaluate the periodontal health of patients with Parkinson Disease (PD) in a Spanish cohort. Material and Methods: A cross-sectional study was performed on 104 patients with PD (mean age: 66.19+9.3 years) and 106 controls (mean age: 59.26+14.11 years). A pre-designed clinical protocol was implemented, which included a standardized epidemiological index for periodontal disease (CPITN), clinical attachment loss (CAL), tooth-loss, full mouth plaque index (FMPI), and oral hygienic habits. Univariate descriptions and comparative analysis were performed. Results: The majority of PD patients presented good oral hygienic habits. There were no significant d…
Effects of Boulder Arrangement on Flow Resistance Due to Macro-Scale Bed Roughness
2023
Flow resistance in gravel-bed channels is not only affected by the shape and size of the roughness elements, but also by their arrangement on the channel bed surface (position to flow streamlines, spacing between elements, and their protrusion from the channel bed). Many investigations proved that open channel flow resistance can be obtained by integrating the power velocity profile. For a macro-scale roughness condition, this study aims to investigate the effect of different boulder arrangements on flow resistance. First, for each arrangement, the equation relating Γ function of the power velocity profile, the Froude number, and the channel slope was calibrated using available measur…
High Resolution-magic Angle Spinning NMR Study of Olive Leaves
2013
In recent years HR-MAS 1H NMR spectroscopy has proven to be a useful tool for the rapid determination of the metabolic profile of several solid and semisolid foods, such as fruits and vegetables, cheese and meat. Olive leaves are today recognized as direct sources of bioactive compounds and natural antioxidants (flavonoids, secoiridoids) suitable as food additives, and their extracts form the basis of beauty care products and pharmaceutical supplements. Thus, olive leaves are emerging as a new and potentially important product for olive tree growing regions. In this report we present the application of 1H and 13C HR-MAS 1D and 2D NMR spectroscopy for the characterization and analysis of tri…
Classification of tall-forb vegetation in the Pamir-Alai and western Tian Shan Mountains (Tajikistan and Kyrgyzstan, Middle Asia)
2020
Aims: To complete the syntaxonomic scheme for tall-forb vegetation of the montane and alpine belts in the Pamir-Alai and western Tian Shan Mountains in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. Study area: Middle Asia: Tajikistan and Kyrgyzstan. Methods: A total of 244 relevés were sampled in 2013–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. These were classified with a modified TWINSPAN algorithm with pseudospecies cut-levels 0%, 5% and 25%, and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. NMDS was used to explore the relationsh…
"LA FINANZA PER L'ESTERO:IL PUNTO DI VISTA DELLE BANCHE LOCALI E DELLE PMI MARCHIGIANE"
2009
Questo studio descrive la relazione tra funzione finanziaria e strategie di internazionalizzazione delle PMI, visto che non risulta possibile tracciare una netta linea di demarcazione tra aspetti finanziari e di economia reale, soprattutto a seguito delle sfide competitive lanciate dalla globalizzazione e dalla diffusione di un nuovo modo di concepire il rapporto banca-impresa secondo le regole di Basilea 2. Un’attenta analisi degli aspetti attinenti sia all’offerta da parte delle banche locali della Regione Marche di prodotti/servizi finanziari volti a favorire l’ingresso delle PMI nei mercati esteri, in modo da poter valutare quanto tali prodotti/servizi siano conosciuti dalle banche loca…
Persistence in complex systems
2022
Persistence is an important characteristic of many complex systems in nature, related to how long the system remains at a certain state before changing to a different one. The study of complex systems' persistence involves different definitions and uses different techniques, depending on whether short-term or long-term persistence is considered. In this paper we discuss the most important definitions, concepts, methods, literature and latest results on persistence in complex systems. Firstly, the most used definitions of persistence in short-term and long-term cases are presented. The most relevant methods to characterize persistence are then discussed in both cases. A complete literature r…
Adverse reactions to the injection of face and neck aesthetic filling materials: a systematic review
2022
Adverse reactions, caused during the inflammation and healing process, or even later, can be induced by the injection of dermal filler and can present a variety of clinical and histological characteristics. In this study we aimed to review the adverse reactions associated with the injection of aesthetic filling materials in the face and neck. The review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Studies published that mentioned adverse reactions in patients with aesthetic filling materials in the face or neck were included. Risk of bias was assessed using the Joanna Briggs Institute appraisal tool. After a 2-step selection pro…

Characterizing Cavities in Model Inclusion Fullerenes: A Comparative Study
2001
Abstract: The fullerene-82 cavity is selected as a model system in order to test several methods for characterizing inclusion molecules. The methods are based on different technical foundations such as a square and triangular tessellation of the molecular surface, spherical tessellation of the molecular surface, numerical integration of the atomic volumes and surfaces, triangular tessellation of the molecular surface, and cubic lattice approach to the molecular volume. Accurate measures of the molecular volume and surface area have been performed with the pseudorandom Monte Carlo (MCVS) and uniform Monte Carlo (UMCVS) methods. These calculations serve as a reference for the rest of the meth…
