    Get PDF
    Objective: To determine the optimum surgical treatment for oral antral communications (OAC) and to understand the main post-operative complications.Study Design: Meta-analytical, observational and retrospective study of 1,072 cases of OAC obtained from a literature review of 15 articles. Results: OAC occur slightly more often in men and during the fourth decade of life. Its primary etiological factor is dental extraction, most often affecting the third molar. The most common treatment has been the use of Bichat's fat pad grafts, whereas the technique with the highest percentage of complications has been the use of the palatal rotation flap. The most frequent complication has been the fistulization of the OAC. Conclusions: Early diagnosis of OAC and its treatment within 48 hours of evolution are fundamental in order to properly resolve this pathology. The use of Bichat's fat pad grafts is a simple technique that offers excellent vascularization and results. © Medicina Oral

    Get PDF
    (1) Background: The introduction of Information and communication technologies (ICTs) in the area of Physical Education is a very recent phenomenon, and its implementation is a challenge for teachers in Spain. It implies pedagogic innovation for the improvement of the teaching and learning processes, especially for people with a disability (functional diversity). The aim of this study was to identify the degree of technological knowledge (ICT) of the physical education teachers for students with disabilities. (2) Methods: A sample of 341 Physical Education teachers from Spain volunteered for this cross-sectional study. A questionnaire named “DIFOTICyD”, created “ad hoc” was used as the data-gathering instrument. (3) Results: the results revealed the low training of the participants with respect to the use of the ICTs in the field of disability. The degree of training of the teachers was determined by the personal (gender, age), professional (teaching experience) and educational (training received) outcomes. (4) Conclusions: the findings of the study point to the need for didactic training that can be used to train the Physical Education teachers to use ICTs in order to facilitate the learning and educational innovation of students with disabilities.The study has been funded by the Spanish Ministry of Economy and Competitiveness, within the framework of the State Plan for the Promotion of Scientific and Technical Research of Excellence 2013–2016 (DIFOTICYD EDU2016 75232-P)

    Revalorization of Broccoli By-Products for Cosmetic Uses Using Supercritical Fluid Extraction

    Get PDF
    The agri-food industry is currently one of themain engines of economic developmentworldwide. The region ofMurcia is a reference area in Europe for the cultivation of fruits and vegetables and produces the bulk of Spanish exports of broccoli (Brassica oleracea var. italica). The processing of fresh produce generates a huge number of by-products that represent an important economic and environmental problem when discarded. In this work, an advanced extraction technique using environmentally friendly solvents was applied to assess the revalorization of broccoli by-products, by performing a comparative analysis with conventional extraction. To achieve this goal, supercritical fluid extraction based on response surface methodology was performed using CO2 and ethanol as solvents. The results obtained showed that the supercritical fluid extracts were rich in -carotene, phenolic compounds, chlorophylls and phytosterols. Moreover, in bioactivity assays, the supercritical fluid extracts exhibited a high antioxidant activity and a cytoprotective effect in a non-tumorigenic keratinocyte cell line exposed to ultraviolet B light. The results indicate that supercritical fluid extracts from broccoli by-products could potentially serve as an ingredient for cosmetic purposes

    Get PDF
    The European Higher Education Area is assuming a change in the teaching-learning of all European universities. The area of Marketing, traditionally characterized by being at the forefront in terms of educational innovation, faces the challenge of finding new tools to facilitate the work of students by encouraging their involvement in the acquisition of new skills. This paper analyzes the capacity that the development of case studies has to develop skills and competencies by the students, which are defendants in the framework of the European Higher Education Area to suit the environment established in the labor market. To this end, it is analyzed the experience and the main conclusions of the practices carried out at the University of Castilla-La Mancha, with the participation of student groups at an international conference aimed at developing teaching cases in public and nonprofit marketing

    A sensitive nanosensor for the in situ detection of the cannibal drug

    Full text link
    [EN] A bio-inspired nanodevice for the selective and sensitive fluorogenic detection of 3,4- methylenedioxypyrovalerone (MDPV), usually known as Cannibal drug, is reported. The sensing nanodevice is based on mesoporous silica nanoparticles (MSNs), loaded with a fluorescent reporter (rhodamine B) and functionalized on their external surface with a dopamine derivative (3), which specifically interacts with the recombinant human dopamine transporter (DAT), capping the pores. In the presence of MDPV, DAT detaches from the MSNs consequently causing rhodamine B release and allowing drug detection. The nanosensor shows a detection limit of 5.2 µM and it is able to detect the MDPV drug both in saliva and blood plasma samples.The authors thank the Spanish Government (projects RTI2018-100910-B-C41 (MCUI/AEI/FEDER, UE) and CTQ2017-87954-P) and the Generalitat Valencia (PROMETEO/2018/024) for support.

    Nanosensor for Sensitive Detection of the New Psychedelic Drug 25I-NBOMe

    This is the peer reviewed version of the following article: E. Garrido, M. Alfonso, B. Díaz de Greñu, B. Lozano-Torres, M. Parra, P. Gaviña, M. D. Marcos, R. Martínez-Máñez, F. Sancenón, Chem. Eur. J. 2020, 26, 2813, which has been published in final form at https://doi.org/10.1002/chem.201905688. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] This work reports the synthesis, characterization, and sensing behavior of a hybrid nanodevice for the detection of the potent abuse drug 25I-NBOMe. The system is based on mesoporous silica nanoparticles, loaded with a fluorescent dye, functionalized with a serotonin derivative and capped with the 5-HT2A receptor antibody. In the presence of 25I-NBOMe the capping antibody is displaced, leading to pore opening and rhodamine B release. This delivery was ascribed to 5-HT2A receptor antibody detachment from the surface due to its stronger coordination with 25I-NBOMe present in the solution. The prepared nanodevice allowed the sensitive (limit of detection of 0.6 mm) and selective recognition of the 25I-NBOMe drug (cocaine, heroin, mescaline, lysergic acid diethylamide, MDMA, and morphine were unable to induce pore opening and rhodamine B release). This nanodevice acts as a highly sensitive and selective fluorometric probe for the 25I-NBOMe illicit drug in artificial saliva and in sweets.The authors thank the Spanish Government (projects RTI2018-100910-B-C41 (MCUI/AEI/FEDER, UE) and CTQ2017-87954-P) and the Generalitat Valencia (PROMETEO/2018/024) for support.

    Gene-Directed Enzyme Prodrug Therapy by Dendrimer-Like Mesoporous Silica Nanoparticles against Tumor Cells

    [EN] We report herein a gene-directed enzyme prodrug therapy (GDEPT) system using gated mesoporous silica nanoparticles (MSNs) in an attempt to combine the reduction of side effects characteristic of GDEPT with improved pharmacokinetics promoted by gated MSNs. The system consists of the transfection of cancer cells with a plasmid controlled by the cytomegalovirus promoter, which promotes ß-galactosidase (ß-gal) expression from the bacterial gene lacZ (CMV-lacZ). Moreover, dendrimer-like mesoporous silica nanoparticles (DMSNs) are loaded with the prodrug doxorubicin modified with a galactose unit through a self-immolative group (DOXO-Gal) and modified with a disulfide-containing polyethyleneglycol gatekeeper. Once in tumor cells, the reducing environment induces disulfide bond rupture in the gatekeeper with the subsequent DOXO-Gal delivery, which is enzymatically converted by ß-gal into the cytotoxic doxorubicin drug, causing cell death. The combined treatment of the pair enzyme/DMSNs-prodrug are more effective in killing cells than the free prodrug DOXO-Gal alone in cells transfected with ß-gal.This research was funded by the Spanish Government (projects RTI2018-100910-B-C41, RTI2018-101599-B-C22 and SAF2017-84689-R (MCUI/FEDER, EU)) and the Generalitat Valenciana (projects PROMETEO 2018/024 and PROMETEO/2019/065).

    The role of meta-cognitive certainty on pornography consumption

    Full text link
    Background: The Problematic Pornography Use Scale (PPUS) was originally designed to help predicting pornography consumption. Despite the frequency with which this scale is used in the scientific literature, there is still relatively little evidence regarding the predictive validity of this important instrument. This current research introduces a construct capable of improving the ability of the scale to predict pornography consumption (meta-cognitive certainty). Method: Over two studies, participants completed the PPUS and the meta-cognitive certainty in their responses to the scale was measured (Study 1) or manipulated (Study 2). Self-reported porn consumption was the criterion measure in both studies, with an additional actual overt behavior relevant to consumption of porn included in Study 2. Results: As expected, the PPUS significantly predicted porn consumption, confirming the predictive validity of the scale. More importantly, meta-cognitive certainty was capable of moderating the extent to which scores on the PPUS could predict porn consumption, with greater consistency between the PPUS and reported behavior from those with high (vs. low) meta-cognitive certainty. Conclusions: These data suggest that considering meta-cognitive certainty may be useful for predicting when the link between the PPUS and porn consumption is stronger.Research was supported by the Ministerio de Ciencia e Innovación y Universidades, Gobierno de España (ES) [PSI2017- 83303-C2-1-P].
