Turbulence in River and Maritime Hydraulics
2018
Understanding of the role of turbulence in controlling transport processes is of paramount importance for the preservation and protection of aquatic ecosystems, the minimisation of deleterious consequences of anthropogenic activity, and the successful sustainable development of river and maritime areas. In this context, the present Special Issue collects 15 papers which provide a representation of the present understanding of turbulent processes and their effects in river and maritime environments. The presented collection of papers is not exhaustive but it allows for highlighting key priority areas and knowledge gaps in this field of research.
Challenges in dental statistics: survey methodology topics
2022

 This paper gathers some contributions concerning survey methodology in dental research, as discussed during the first Workshop of the SISMEC STATDENT working group on statistical methods and applications in dentistry, held in Ancona on the 28th September 2011.
 The first contribution deals with the European Global Oral Health Indicators Development (EGOHID) Project which proposed a comprehensive and standardized system of epidemiological tools (questionnaires and clinical forms) for national data collection on oral health in Europe. The second contribution regards the design and conduct of trials to evaluate the clinical efficacy and safety of toothbrushes and mouthrinses. Final…
Antibiotic susceptibility of the bacteria causing odontogenic infections
2006
Objetivos: Identificar la flora bacteriana y su susceptibilidad a varios antibióticos utilizados en infecciones odontogénicas de localización periapical y en las pericoronaritis del tercer molar inferior, para poder adaptar convenientemente el tratamiento antibiótico a las exigencias de tales infecciones, y evitar así los efectos secundarios y los sobretratamientos con antibióticos. Material y métodos: Se han seleccionado con unos criterios de inclusión y de exclusión a 64 pacientes que presentaban una infección odontogénica. Se recogieron muestras de las lesiones en condiciones de máxima asepsia, evitando la contaminación por flora saprófita bucal. Las muestras se sembraron en medios de cu…
Efficacy of the laser at low intensity on primary burning oral syndrome: a systematic review.
2020
Background Primary burning mouth syndrome (BMS) is a chronic clinical condition of idiopathic mainly characterized by pain and a burning sensation in the oral cavity. The application of laser at low intensity therapy is a treatment option. This systematic review evaluated the efficacy of laser therapy in treating symptoms of burning mouth syndrome. Material and Methods The study was formulated according to the PRISMA and Cochrane guidelines. Seven databases were used as primary sources of research. Only randomized controlled clinical trials were included. The efficacy of the therapy was estimated comparing the values of the visual and numerical scales of pain before and after laser treatmen…
Analyzing heterogeneity on the value, satisfaction, word-of-mouth relationship in retailing
2017
Purpose The literature recognizes the need to study differences in consumer behavior in highly competitive and dynamic markets. In this paper, the authors look at how the heterogeneous evaluation of retailing influences customer satisfaction and loyalty. The purpose of this paper is to analyze unobserved heterogeneity on customer value dimensions perceptions in retail establishments, and their potential effects on positive forms of behavioral outcomes considering customer satisfaction as a mediating variable. Design/methodology/approach On a sample of 820 retail customers, the authors apply a finite mixture structural equation modeling that analyzes unobserved heterogeneity simultaneously.…
Quelles stratégies pour les musées sur internet ? Entre " click and mortar " et " mortar and click "
2011
Many companies now use the Internet as part of a click & mortar strategy. This strategy is also used in the museum field, but its consequences have not been evaluated yet. A quantitative study carried out on a sample of 388 visitors, at the Bibracte Museum (France), indicates that the quality of an internet website, as well as the satisfaction and trust experienced by Internet users when browsing, have direct positive influence on word-of mouth and the actual museum visit. It seems therefore appropriate to integrate the internet website to the whole management of cultural and artistic activities, without forgetting to take into account the specificities of this particular field.
Association of burning mouth syndrome with xerostomia and medicines
2005
Objetivo: Identificar factores de riesgo para el síndrome de boca ardiente (SBA) a través de estudio de casos y controles. Material y métodos: Se realizó análisis cuantitativo del flujo salival total en reposo y estimulado; se registraron la xerostomía subjetiva, el consumo de medicamentos y los estados psicológicos de ansiedad y depresión en 40 pacientes con SBA y 40 controles. Resultados: El análisis ANOVA mostró diferencias significativas en las medias del número de medicamentos/día, número de medicamentos xerostomizantes/día, xerostomía subjetiva, ansiedad y depresión, entre los grupos estudiados. No se observaron diferencias significativas en las tasas de flujo salival en reposo y esti…
The Human Mammary Odour Factor: Variability and Regularities in Sources and Functions
2019
In the course of evolution, human mothers have been, and still are, under strong selective pressure to induce their newborns’ colostrum ingestion promptly after birth. As a concentrate of nutrients, passive immunity, antioxidants, growth factors and symbiotic microbiota, colostrum functions as the evolved antidote to ubiquitous pathogens and threats of neonatal exhaustion. Under such constraints, any means to speed up colostrum/milk intake can only have been beneficial to neonatal viability and adaptive life onset along evolutionary time. The areolar-nipple areas of human lactating females emit lacteal substrates conveying chemostimuli that are attractive and release mouthing and sucking in…
Validation of ATP bioluminescence as a tool to assess antimicrobial effects of mouthrinses in an in vitro subgingival-biofilm model
2012
Objectives. The aim of this investigation was to evaluate whether the adenosine triphosphate (ATP) bioluminescence method is an appropriate tool to assess the efficacy of antiseptic mouthrinses in terms of quantitative reductions of total viable microbial counts in mixed biofilm populations in vitro. Study Design. Three mouthrinses, containing respectively, chlorhexidine and cetylpyridinium chloride (CHX/CPC), essential oils (EO) and amine fluoride/stannous fluoride (AFSF), as well as Phosphate Buffered Saline (PBS) used as control, were tested in an in vitro static biofilm model by ATP bioluminescence and compared to culture method. Biofilms were grown on saliva-coated hydroxyapatite disks…
The use of three-dimensional oral mucosa cell cultures to assess the toxicity of soldered and welded wires
2007
The aim of the present study was to determine whether there is a difference in toxicity and loss of viability of three-dimensional (3D) reconstructed human oral epithelium (RHOE) cell cultures induced by point-welded (PW), laser-welded (LW), and silver-soldered (SiS) orthodontic wires. Three types of soldered stainless steel (SS) wires: PW, LW, and SiS were prepared ( n = 3) and subjected to multiple end-point analysis (MEA). Six pieces were cut from each wire. Each piece was placed on the triplicate cell cultures (RHOE model based on TR 146 cells). After 24 hours of topical exposure, the cell cultures were cut and stained with haematoxylin/eosin. Toxicity was assessed by evaluating the mor…
