Cellusim: Un simulador 3D en entorno videojuego para la docencia del laboratorio de cultivos celulares

2018

[EN] Cell cultures allow the maintenance of living cells outside the body. This technique is fundamental to study the biological, biochemical and physiological properties of cells and can be used as an experimental model in vitro in the field of biomedical research. The teaching in the laboratory of this technique presents numerous difficulties at a practical, logistical and economic level. On the other hand, the learning of cell culture protocols is an important part of the student's training in Cell Biology. Based on the routine practices carried out within a cell culture laboratory, we have developed the virtual 3D simulator of a cell culture laboratory "Cellusim". In "Cellusim" you can …

Design characteristics, primary stability and risk of fracture of orthodontic mini-implants: Pilot scan electron microscope and mechanical studies

2013

Objectives: Orthodontic mini-implants (OMIs) are increasingly used in orthodontics but can fail for various reasons. This study investigates the effects of OMI design characteristics on the mechanical properties in artificial bone. Material and Methods: Twelve self-drilling OMIs (2 small, 6 medium, 4 large) from 8 manufacturers were tested for their primary stability in simulated medium-high cancellous bone and the risk to fracture in high-density methacrylate blocks. For the assessments of the maximum insertion torque (IT) and torsional fracture (TF) 5 of each OMI were used and for the pull-out strength (POS) 10. The OMIs were inserted with a torque screwdriver (12 sec/360°) until the bott…

Costochondral Grafts in the treatment of Temporomandibular joint ankylosis: a Clinical Study

2011

Background: Treatment of temporomandibular joint (TMJ) ankylosis usually requires adequate excision of the involved ankylotic block (arthroplasty) without interposing any material (gap arthroplasty) or interpositional arthroplasty using autogenous or alloplastic materials. The objective of this paper was to note the potential of the costochondral graft (CCGs) as an interpositional material and to see whether they induce normal growth potential in the reconstructed mandible. Materials and method: The ankylosed temporomandibular joint was reached by a preauricular incision with or without angulation and exposed. In the first 4 cases, arthroplasty was done using a bur. The bony mass was detach…

Assessment of Osstell ISQ's reliability for implant stability measurement: a cross-sectional clinical study

2013

Resonance frequency analysis (RFA) allows assess implant stability by measuring implant oscillation frequency on the bone. RFA is an objective and non-invasive method for implant stability measurement, although scarce evidence has been provided so far on its reliability. Objectives: Assess the Osstell ISQ system's reliability (i.e., its measurement reproducibility and repeatability) by means of the intraclass correlation coefficient (ICC) as statistical method. Study Desing: Implants stability registers were completed by means of Osstell ISQ on 85 implants on 23 patients. Six measurements were completed on each implant by means of two different SmartPegs (types I and II); that is, three con…

Bebiendo como chicos: consumo compartido de alcohol y rupturas de género en poblaciones adolescentes

2015

La información epidemiológica en España pone en evidencia los cambios que se vienen sucediendo en los patrones de consumo de alcohol en las poblaciones adolescentes. Estos son especialmente significativos en relación a la reducción de la brecha en los consumos intensivos de alcohol por parte de las chicas. Este artículo tiene como objetivo describir algunos elementos que, imbricados al sistema de género, muestran tendencias de lo que está sucediendo en relación al consumo de alcohol en las poblaciones adolescentes. Para ello fue diseñado un estudio cualitativo en base a grupos focales con chicas y chicos de 14 a 17 años. Los discursos de los 66 adolescentes andaluces participantes en el est…

Efficacy of the NaviTip FX irrigation needle in removing calcium hydroxide from root canal

2012

Objective: To evaluate the effectiveness of the NaviTip FX, brush-covered irrigation needle, in removing calcium hydroxide from the root canal. Study Design: Thirty single-rooted teeth were randomly divided into three groups: A - irrigation with a hypodermic needle inserted as far as possible without binding and activation with #30 K-type file; B - Irrigation with a hypodermic needle without activation; C - irrigation with NaviTip FX needle. Sodium hypoclorite 1% was used in irrigation. The root canals were examined trough scanning electron microscopy. Calcium hydroxide removal was recorded at 1, 5, and 10mm from the working length (WL) and the data were analysed using one-way ANOVA test (p…

Condylar distances in hypermobile temporomandibular joints of patients with excessive mouth openings by using computed tomography

2014

Objectives: hypermobility in Temporomandibular joint (TMJ) can manifest higher range of motions in mandible. The aim of this study was to compare the position and distances of the head of condyle to glenoid fossa in TMJs of healthy individuals and patients with mild, moderate and severe TMJ hypermobility. Material and Methods: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of joint hypermobility were included and Computed tomography were administered for both TMJs. The patients were divided into three groups based on their maximum mouth opening (MMO): (A) with MMO of 50-55 mm; (B) with MMO between 55 to 65 mm; and (C) with MMO >65 mm. Also, 15 healthy …

Pancreatitis aguda necrótico-hemorrágica: propósito de dos autopsias judiciales

2015

la pancreatitis necrótico-hemorrágica, es una complicación inusual y altamente mortal en los casos de inflamación de la glándula pancreática. El diagnóstico es de sospecha clínica apoyado por pruebas de laboratorio y de radiodiagnóstico. Constituye una causa excepcional de muerte súbita. Pero esta forma de presentación de pancreatitis sólo puede ser confirmada mediante el estudio anatomopatológico de la glándula, del cual se dispone en raras ocasiones. Exponemos los hallazgos macroscópicos de dos casos mortales de Pancreatitis Aguda Necro-Hemorrágica. hemorrhagic and necrotizing pancreatitis, is an unusual and highly lethal complication in cases of inflammation of the pancreatic gland. The …

Solitary keratoacanthoma involving upper lip: a diagnostic dilemma - case report and a brief review

2010

Keratoacanthoma (KA) is a benign epithelial proliferative lesion which frequently occurs on the sun exposed areas of the skin. KA originates within the pilosebaceous apparatus of the skin and may be solitary or multiple. Solitary KA can be difficult to differentiate from squamous cell carcinoma (SCC) both clinically and microscopically. However, the clinical course of the lesion and its ability to self involute makes it a distinct clinical entity. Solitary KA appears on the vermilion border of the lower lips with some frequency. A case of keratoacanthoma involving the upper lip is reported presenting as an exophytic growth that resolved after excisional biopsy. Photo- graphic documentation …
