Background: Separation methods of local anesthesia to diffuse and vascular must significantly affect the clinical effect of adrenaline containing local anesthetic (mepivacaine). The aim of this prospective, randomized, controlled studies µAde was to compare the degree of anesthesia of intact upper lateral incisor the cartridge ¼ 3% mepivacain without epinephrine in the group after the infiltration and after intraligamentary anesthesia (ILA) in the experimental group. Methods: Anesthesia performed computer syringe Sleeper One 86 subjects aged 20-23 years. In all cases, aspiration was performed. With pulp tester IVN-01 measured the pain threshold incisors and canines in microamperes during the anesthetic effect. Results: Reference level of all researched teeth (86 subjects) was ranged from 1 to 10 µA. Uniform pain threshold increase to 95 (±20) µA by 5 min. watched during infiltration anesthesia then this value gradually descended to reference level (by 20 min.). Peak single increase of pain threshold to 55 (±8,9) µA occurred immediately after 1st minute of ILA, then this value subsequently drops to reference level (10 µA) by 20 minutes. Difference between groups of infiltration and intraligamentary anesthesia (ILA+ red) and (ILA – green) presented on Chart 6. Conclusions: Infiltration anesthesia with mepivacaine without epinephrine smoothly diffusely increased the pain threshold of the front teeth, reaching a significant, maximum effect by 5 minutes. Intraligamentary injection immediately after administration created a peak increase in pain sensitivity at a lower level, almost without the participation of the diffuse component.

The purpose of this article is to determine the orientation and relative position of the foot bones in Weight Bearing CT, highlighting the effect of the load and the shoe with the heel. Thanks to a Cone Beam CT (OnSight 3D Extremity System, Carestream) equipment, three scans of the foot of a healthy young subject were carried out in three conditions: "unloading", "loading", and wearing a shoe with "heel". In order to assess the accuracy of the articular angles of the foot through non-invasive measurements, a measurement was performed by Gait-Analysis with passive markers in the same conditions. The effect of the "load" resulted in a significant alteration of the foot posture especially in the sagittal plane, with crushing of the longitudinal medial arch. The heeled shoe involves enormous deformations at the level of the metatarsophalangeal joints and the ankle.

ABSTRACTHow can we approach the process of construction of young men and women as subjects in the case of a group of high school students, who, in some cases, come from the families of maya origin and are inhabitants of a marginalized urban area in the southeast of Mexico? In this paper I argue that their way of being, relationship with structures, future projects, and notions of “good life” become intelligible through an approach that puts into dialogue the concepts of social experience (Dubet, 2011) and otherness. The first one is a valuable tool that allows to discover a particular dialectic of integrationsubjectivation, which characterizes the relationship of these young people with social institutions and actors. The second one locates the students as constructors of a symbolic universe, where different cultural elements, among them those originated in the family and in school, interact. The representation of a young subject that I construct differs from the stereotypes – usually negative and homogeneous– that are used to describe the urban area in question; it also allows to understand the necessities and aspirations of these individuals according to their own notions of good life, in which the individual and the communal aspects are merged.RESUMEN¿Cómo podemos estudiar la construcción del sujeto en el caso de un grupo de jóvenes estudiantes de un bachillerato universitario, algunos de los cuales provienen de las familias de origen maya, habitantes de una zona urbana marginal, en el sureste de México? Arguyo que su forma de ser, relación con las estructuras, proyectos a futuro y nociones de la vida buena cobran inteligibilidad mediante un acercamiento que pone a dialogar los conceptos de experiencia social (Dubet, 2011) y alteridad. El primero representa una herramienta conceptual valiosa para descubrir una dialéctica sui géneris de integración-subjetivación que caracteriza la relación de estos jóvenes con las diversas instituciones y actores sociales. El segundo ubica a los jóvenes como constructores de un universo de sentido, en el que interactúan elementos culturales propios de sus familias de origen y el bachillerato universitario, entre otros. La representación del sujeto joven que construyo se aleja de aquellos estereotipos –generalmente negativos y homogeneizantes– que circulan acerca de los jóvenes de la zona en cuestión; asimismo permite comprender las necesidades y aspiraciones de estos individuos acorde a sus propias nociones de la vida buena en las cuales se funden lo individual y lo comunal.

Although a relatively young subject, the historiography of Irish architecture has had a remarkably significant impact on the manner in which particular styles have been interpreted and valued. Since the genesis of the topic in the mid-eighteenth century, specific styles of architecture have been inextricably connected with the political history of the country, and each has been associated with the political and religious affiliations of its patrons. From the mid-nineteenth century, the focus on identifying an Irish ‘national’ architecture became particularly strong, with Early Christian and Romanesque architecture firmly believed to imbue ‘the spirit of native genius’, while Gothic, viewed as the introduction of the Anglo-Norman invader, was seen as marking the end of ‘Irish’ art. Inevitably, with such a strong motivation behind them, early texts were keen to find structures that were untouched by the hand of the colonizer as exemplars of the ‘national architecture’. Scholars, including the pioneering George Petrie (1790–1866) in works such as his 1845 study of the round towers of Ireland, believed that through historical research he and others were the first to understand the ‘true value’ of these buildings and that any former interest in them had been purely in their destruction, rather than in their restoration or reconstruction. It was believed that such examples of early medieval architecture and sculpture as had survived had done so despite, rather than because of, the efforts of former ages, and, although often in ruins, the remains could be interpreted purely in terms of the date of their original, medieval, creation.Informed by such studies, from the mid-nineteenth century a movement grew to preserve and consolidate a number of threatened Romanesque buildings with the guiding philosophy of preserving the monuments as close to their original ‘pre-colonial’ form as possible. Consolidation of the ruins of the Nuns’ Church at Clonmacnoise (Co. Offaly) is traditionally amongst the earliest and most celebrated of these endeavours, undertaken by the Kilkenny and Southeast Ireland Archaeological Society in the 1860s, setting a precedent for both the type of monument and method of preservation that was to become the focus of activity from the 1870s, and thus for the first State initiatives in architectural conservation.

We developed a balance measurement tool (the balanced reach test (BRT)) to assess standing balance while reaching and pointing to a target moving in three-dimensional space according to a sum-of-sines function. We also developed a three-dimensional, 13-segment biomechanical model to analyze performance in this task. Using kinematic and ground reaction force (GRF) data from the BRT, we performed an inverse dynamics analysis to compute the forces and torques applied at each of the joints during the course of a 90 s test. We also performed spectral analyses of each joint's force activations. We found that the joints act in a different but highly coordinated manner to accomplish the tracking task—with individual joints responding congruently to different portions of the target disk's frequency spectrum. The test and the model also identified clear differences between a young healthy subject (YHS), an older high fall risk (HFR) subject before participating in a balance training intervention; and in the older subject's performance after training (which improved to the point that his performance approached that of the young subject). This is the first phase of an effort to model the balance control system with sufficient physiological detail and complexity to accurately simulate the multisegmental control of balance during functional reach across the spectra of aging, medical, and neurological conditions that affect performance. Such a model would provide insight into the function and interaction of the biomechanical and neurophysiological elements making up this system; and system adaptations to changes in these elements' performance and capabilities.
