Langerin+ DCs regulate innate IL-17 production in the oral mucosa during Candida albicans-mediated infection
2018
The opportunistic fungal pathogen Candida albicans frequently causes diseases such as oropharyngeal candidiasis (OPC) in immunocompromised individuals. Although it is well appreciated that the cytokine IL-17 is crucial for protective immunity against OPC, the cellular source and the regulation of this cytokine during infection are still a matter of debate. Here, we directly visualized IL-17 production in the tongue of experimentally infected mice, thereby demonstrating that this key cytokine is expressed by three complementary subsets of CD90+ leukocytes: RAG-dependent αβ and γδ T cells, as well as RAG-independent ILCs. To determine the regulation of IL-17 production at the onset of OPC, we…
Predictability of the resonance frequency analysis in the survival of dental implants placed in the anterior non-atrophied edentulous mandible.
2010
Background: Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. Patients and Methods: Seventy patients with complete mandibular edentulism underwent dental implant rehabilitation by means of the placement of 68 dental implants within the interforaminal region and subsequent placement of an overdenture. Primary implant stability was measured by means of RFA and it was expressed in terms of imPrimary implant stability was measured by means of RFA an…
CBCT location of the fusion between the buccal and lingual cortical in the mandibular ramus : importance to sagittal split osteotomy
2016
Background Mandibular Sagittal Split Osteotomy (MSSO) is a popular technique in orthognathic surgery used both to advance and to retreat the mandible. However, MSSO may incur in important complications, such as bad splits and sensorineural injuries. Knowing the location of the fusion between the buccal and lingual cortical (FBLC) in the mandibular ramus and the bone thickness in the region where osteotomies will be performed is determinant in MSSO planning to avoid complications. The aim of this study was to document and evaluate possible differences between sexes regarding the location of the FBLC in relation to the superior cortical of mandibular foramen (MF) and bone thickness in the reg…
Validation of the oral health impact profile (OHIP-20sp) for Spanish edentulous patients
2011
Objectives: The purposes of this study are to validate the indicator of Oral Health Impact Profile for edentulous patients (OHIP-20sp) in the Spanish population and to analyze the factorial construct of the prosthetic well-being. Study Design: A total of twenty-one (n=21) edentulous patients wearing mandibular implant-over dentures on Locator® (LO) and twenty (n=20) with complete dentures (CD) were retrospectively evaluated in this study. All participants were recruited consecutively and were treated in the previous academic year 2009-2010 by professors of the University of Salamanca. Reliability analyses and validity tests were performed in order to evaluate the psychometric properties of …
Oral conditions and salivary analysis in HIV-uninfected subjects using preexposure prophylaxis.
2021
New prevention strategies have been advocated to control the progression of HIV/AIDS, such as preexposure prophylaxis (PrEP). The aim of this study is to evaluate the potential changes in the oral and salivary conditions of HIV-uninfected subjects using PrEP. Subjects were evaluated before beginning the medication (T0), at the first follow-up (T1), and at the second follow-up (T2). Xerostomia, presence of untreated cavitated caries, oral hygiene habits, taste, gingival and plaque index, stimulated salivary flow rate (SSFR), and salivary concentrations of calcium, glucose, urea, and total proteins were evaluated. Data obtained were analyzed using statistical tests (p0.05), except for the sal…
Human newborns match tongue protrusion of disembodied human and robotic mouths
2011
International audience; No evidence had been provided so far of newborns' capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an artificial tongue from a robotic mouth. Compared to a baseline condition, neonates increased significantly their tongue protrusion when seeing disembodied human and artificial tongue movements, but not when seeing a 2D full-face protruding tongue. This result was interpreted as revealing the exploration of top-heavy patterns o…
Positive and negative word of mouth (WOM) are not necessarily opposites: A reappraisal using the dual factor theory
2021
Prior research has not systematically investigated the enablers and inhibitors in conjunction to measure consumer behavior toward mobile wallets (m-wallets), focusing either on the adoption or the resistance perspective only. Similarly, antecedents and consequences of the dichotomous nature of word of mouth for m-wallets have also remained obscure so far. The present research proposes to address this void in the accumulated learnings by examining both enablers and inhibitors of mobile wallets (m-wallets) as antecedents of valence of word of mouth (positive and negative; PWOM and NWOM, respectively). Grounded in Dual Factor Theory, this study aims to explore consumers’ continued use intentio…
Positive gender congruency effects on shopper responses:Field evidence from a gender egalitarian culture
2021
National audience; This field study examined how customer-employee interactions are affected by the congruency between an employee's gender and the perceived gender image of the consumption context in one of the most gender equal cultures in the world (Scandinavia). Mystery shoppers had a service encounter with an employee across a set of physical commercial settings that were classified according to their gender image. The mystery shoppers noted the gender of the employee, provided employee evaluations, and indicated word-of-mouth (WOM) ratings. Shoppers who had a gender congruent service encounter (e.g., a female employee in a “feminine” consumption context) reported more favorable employ…
eWOM on Travel Agency Selection: Specialized versus Private Label
2016
In the travel industry, electronic word of mouth (eWOM) elicits a major influence on consumers’ decision making. Travel retailers are facing the new challenges derived from the different nature of their competitors—big hypermarkets, for instance, are extending their brands to travel services—and the challenges derived from online comments that consumers have access to. With a sample of 263 tourists, and using a fuzzy-set qualitative comparative analysis data analysis, this paper shows how the selection between a specialized travel agency and a private label (PL) agency is influenced by five factors: the usefulness attached to online reviews by users and the valence of those online reviews, …
Identifying future research opportunities in online consumer reviews: the case study of 'TripAdvisor'
2011
Submitted version of an article from the journal: International Journal of Technology Marketing. Published and definitive version available from Inderscience: http://dx.doi.org/10.1504/IJTMKT.2011.045913 The aim of this article is to identify future research opportunities for using online consumer reviews websites such as TripAdvisor.com as a case study. The literature review covers the internet and growth of eTourism, virtual communities, virtual community typologies, and the importance of TripAdvisor.com for travel research, electronic word–of–mouth (eWOM), social networking and the impact of online travel reviews on consumers. Propositions and future research opportunities are then raise…
