Preferencia entre alumnos universitarios de México y Corea del Sur con respecto al perfil y el tercio inferior de la cara

ResumenObjetivoEvaluar la preferencia respecto al perfil facial entre una comunidad de jóvenes estudiantes en Corea del Sur y México durante el 2012.Material y métodos400 encuestas se aplicaron en cuatro facultades de la Universidad Nacional Autónoma de México y en cuatro facultades de la Universidad Nacional de Seúl de Corea del Sur; 50 personas por cada facultad (25 hombres y 25 mujeres). El formato se realizó mediante la obtención de un ideal, y a través de un software se modificó en sentido vertical y sagital para obtener diferentes perfiles y tercios, se realizaron en español y en coreano.ResultadosNo hubo diferencias estadísticas significativas en cuanto al sexo y nacionalidad. El perfil masculino favorito fue el cóncavo y en el femenino fue el convexo, ambos con diferencias estadísticas significativas por profesiones (χ2=19.505 p=.003) (χ2=32.742 p<0.001).ConclusionesEl perfil facial preferido fue el cóncavo en hombres y el convexo en mujeres. El perfil facial que menos gustó es el convexo en hombres y el cóncavo en mujeres. El tercio inferior preferido fue el proporcionado y el que menos agradó fue el tercio inferior disminuido. No hubo diferencias entre nacionalidades ni sexo, pero si por profesiones.AbstractObjectiveTo assess the preference regarding facial profile among a community of young students in South Korea and Mexico in 2012.Material and Methods400 surveys were conducted in 4 faculties of UNAM of Mexico and 4 faculties of the SNU in South Korea, 50 for each faculty (25 men and 25 women). The format was done by obtaining an ideal and through a software sagittal and vertical modifications for different profiles and thirds, were conducted in Spanish and Korean.ResultsThere were no statistically significant differences in gender and nationality. The favorite male profile was concave and the favorite female profile was convex, both with significant statistical difference by occupation (χ2=19.505 p=.003) (χ2=32.742 p<0.001).ConclusionsThe preferred facial profile was concave in men and convex in women. The worst facial profile was convex in men and concave in women. The favorite lower facial third was proportionate and the least liked was a diminished lower third. There were no differences between nationalities or gender, but by professions

Trazos para el mandala en el discurso fílmico de Jodorowsky

Neste artigo, se revisa o filme "El topo" (1970) de Alejandro Jodorowsky, em contraste com a primeira longa-metragem do cineasta chileno, "Fando y Lis" (1968), e com sua produção posterior, "La montaña sagrada" (1973), com a intenção de explicar a construção de espaços simbólicos na dimensão diegética (Bal, 1990; Bordwell e Thompson, 2002), que são recorrentes na obra deste diretor. A escolha dos elementos reside no fato de que cada um deles funciona como microcosmos do sentido (Berruto, 1988), pelo qual foram selecionados os mais reiterativos: o deserto, as residênçias dos mestres e a caverna. É importante destacar que as três histórias têm em comum o tópico da busca, o que permite que sejam comprendidas como um macrodiscurso. Do mesmo modo, se considera a arquitextualidade (Genette, 1989), para mostrar a articulação existente entre as diferentes produções fílmicas selecionadas, buscando uma primeira aproximação a poética visual do autor

Tapón apical de Biodentine en el fragmento coronal en fractura radicular horizontal.

La frecuencia de las fracturas radiculares es menor al 3% de todas las lesiones dentales traumáticas, es responsable del 1% de las pérdidas de la dentición permanente. En las fracturas horizontales ocurre un desplazamiento del segmento coronal que generalmente contrasta con la falta de desplazamiento de la porción apical. En dientes con ápices abiertos está indicada la colocación de una barrera apical, un material de recienteutilización es el BIODENTINE, ya que ofrece bioactividad y propiedades de sellado excelente

Closure of Diastemas, Resin Treatment Option

Introducción: El tratamiento para el cierre de diastemas fundamentalmente está enfocado a otorgar estética y salud periodontal. Los diastemas pueden ser resueltos con prótesis y ortodoncia, sin embargo, estas opciones generalmente requieren de preparaciones del tejido sano, incluyen procedimientos de laboratorio y aumentan el tiempo clínico. La utilización de resinas compuestas constituye una opción estética y funcional para estos casos en los que se requiere de mínima intervención sobre el tejido sano o de ninguna. El propósito de este trabajo es describir el caso de cierre de diastemas en maxilar superior utilizando resinas compuestas híbridas.The treatment for the closure of diastemas is fundamentally focused on granting aesthetics and periodontal health. Diastemas can be solved with prostheses and orthodontics, however, these options generally require healthy tissue preparations, include laboratory procedures and increase clinical time. The use of composite resins is an aesthetic and functional option for these cases in which minimal intervention is required on healthy tissue or none at all. The purpose of this paper is to describe the case of closure of diastemas in the maxilla using hybrid composite resins.Facultad de Odontologí

Growth of functional cranial components in rats with intrauterine growth retardation after treatment with growth hormone

The goal of this study was to analyse the effect of growth hormone (GH) on catch-up growth of functional facial (splanchnocranial) and neurocranial components in rats with intrauterine growth retardation (IUGR). Wistar rats were divided into the following groups: control (C), sham-operated (SH), IUGR, and IUGR + GH. IUGR was surgically induced and GH was administered between 21 and 60 days of age. Radiographs were obtained at 1, 21, 42, 63, and 84 days of age in order to measure length, width, and height of neurocranium (NL, NW, and NH) and face length, width, and height (FL, FW, and FH). Analysis of variance was perfomed at 1 day of age and a principal components analysis (PCA) at 84 days of age. Neurocranial and facial volumetric indexes were calculated as NVI = 3√NL × NW × NH and FVI = 3√FL × FW × FH, respectively, and adjusted by non-linear regression analysis. On postnatal day 1, there were significant differences between SH and IUGR (P IUGR + GH (P < 0.01). The first axis of the PCA exhibited size effect and the second axis showed shape effect. Reductions of placental blood flow modify cranial growth. The functional neurocranial and facial components in rats with IUGR presented different recovery strategies through modular behaviour, mainly related to modifications of growth rate as response to GH administration.Instituto de Genética VeterinariaFacultad de Ciencias Naturales y Muse

Functional Multipotency of Stem Cells: What Do We Need from Them in the Heart?

After more than ten years of human research in the field of cardiac regenerative medicine, application of stem cells in different phases of ischemic heart disease has come to age. Randomized clinical trials have demonstrated that stem cell therapy can improve cardiac recovery after the acute phase of myocardial ischemia and in patients with chronic ischemic heart disease, and several efficacy phase III trials with clinical endpoints are on their way. Nevertheless, a complete knowledge on the mechanisms of action of stem cells still remains elusive. Of the three main mechanisms by which stem cells could exert their benefit, paracrine signaling from the administered cells and stimulation of endogenous repair are nowadays the most plausible ones. However, in this review we will define and discuss the concept of stem cell potency and differentiation, will examine the evidence available, and will depict future directions of research

Manejo endodóntico de órgano dentario con formación radicular incompleta, posterior a reimplante intencional.

El objetivo del tratamiento endodóntico es conservar y devolver la función a los órganos dentarios. Su éxito o fracaso se determina a travéz de signos y síntomas clínicos en correlacion con los hallazgos radiográficos, presentandoun porcentaje de éxito que va del 81 al 97%. Sin embargo, el éxito asociado a reimplante intencional es desconocido.En el caso de fracaso endodóntico, puede recurrirse al retratamiento, pero cuando involucra apices abiertos, la creación de un tapón apical adicional se indica para prevenir una posible extrusión de material de obturación a los tejidos periapicales

Investigating prehistoric diet and lifeways of early farmers in central northern Spain (3000-1500 CAL BC) using stable isotope techniques

This work focuses on reconstructing past diets and animal management during Prehistory in Central Northern Spain, spanning the NE area of the Old Castilian Plateau to the Cantabrian coast, from c. 3000-1500 BCE. During this time, early farming communities made changes in their models of production and social reproduction that crystallised in the emergence of social complexity. To investigate these changes, we reconstructed the past diet of these early farming populations by using stable isotope analysis (?13C, ?15N, ?34S) of human and animal remains from the recently excavated sites of Abrigo de la Castañera in Cantabria and Arroyal I, El Hornazo, Fuente Celada and Ferrocarril-La Dehesa in Burgos. The human remains derived from a range of burial contexts including pit graves, megalithic monuments and burial caves. To provide initial insights into animal management during this timeframe, associated faunal remains were also studied as a baseline. In total, 52 samples were analysed, including 17 human burials and 35 animal specimens (cattle, sheep, pig, red deer and dog). Results show that humans in these sites consumed relatively similar diets, comprising of a predominantly C3 diet including animal protein. Animal management patterns indicate a wider use of the landscape for herbivore grazing. The differing diets of dogs at El Hornazo provide insights into the relationship that they had with humans and tentatively suggests differences in the diet of working animals versus household pets. The ?34S values of two individuals from Arroyal I indicate that they came from different regions, implying a level of inland mobility during the Chalcolithic
