Abstract: Objetivo: Evaluar los beneficios de la estimulación visual usando el microperímetro MP1 en pacientes con baja visión por agujero macular atendidos en consulta de baja visión en el Instituto Cubano de Oftalmología “Ramón Pando Ferrer” en el a o 2010. Métodos: Se realizó un estudio experimental, tipo serie de casos. Fueron estudiadas, antes y después de la rehabilitación, las siguientes variables: agudeza visual mejor corregida de cerca con cartilla Zeiss y agudeza visual mejor corregida de lejos usando cartilla Feinbloom, estabilidad de la fijación y sensibilidad retiniana por medio del microperímetro MP1 y velocidad de lectura. Se realizaron 10 sesiones de estimulación de 10 minutos cada una con una frecuencia semanal, empleando el módulo de “biofeedback” del microperímetro MP1. Se realizó análisis estadístico por medio del test de student para muestras pareadas. Valores de p= 0,05 se consideraron como estadísticamente significativos. Resultados: La agudeza visual para lejos y cerca mejoró de 0,18 a 0,23, y de 0,21 a 0,51 respectivamente, la sensibilidad retiniana aumentó de 2,69 a 7,86 dB, la estabilidad de la fijación antes de la estimulación: inestable (80,77 %), relativamente inestable (15,38 %) y estable (3,85 %) y después de la misma: no inestable, relativamente inestable (30,77 %) y estable (69,23 %). La velocidad de lectura mejoró de 35 a 104 palabras por minuto. Conclusión: La estimulación visual empleando el microperímetro MP1 mejoró el rendimiento visual de los pacientes con agujero macular y baja visión. Objective: To evaluate the benefits of visual stimulation by using the MP1 microperimeter in patients with low vision due to macular hole, who were seen at low vision service of “Ramón Pando Ferrer" Cuban Institute of Ophthalmology during 2010. Methods: An experimental, case series type study was carried out. The following variables were studied before and after the rehabilitation: best near spectacle-corrected visual acuity with Zeiss chart and best distance spectacle-corrected visual acuity with Feinbloom chart, fixation stability and retinal sensitivity by means of the MP1 microperimeter and reading speed. Ten 10-minute sessions of stimulation weekly using the MP1 microperimeter biofeedback module were given. Statistical analysis was performed with paired Student’s t-test. P values less than 0,05 were considered statistically significant. Results: Distance and near visual acuity improved from 0,18 to 0,23, and from 0,21 at 0,51; retinal sensitivity increased from 2,69 to 7,86 dB, fixation stability was unstable (80.77 %), relatively unsta

Beijing Law Review (BLR) , 2016, DOI: 10.4236/blr.2016.71007
Abstract: This paper focuses on some traces of the challenge of the government of the dispersed population into a larger territory of the Spanish Monarchy throughout 16 - 19 century. The main subject is the creation and implementation of a minor justice: the “alcalde de la santa hermandad” (judge of the brotherhood). This rural judge appeared early at Santa Fe and Buenos Aires and plays like an articulator between urban and rural populations. Based on a large base of research, this work shows what was the role that the office holders allowed to play in the political process equipment planning at the Gobernación of Buenos Aires.

Abstract: Objective. To create a ureteral obstruction experimental model that can be proved through -DTPA renal scintigraphy and histopathological studies, without causing total renal function loss. Materials and Methods. Ten New Zealand white rabbits were submitted to a surgical experiment to create a model of unilateral obstruction to urinary flow. Surgery procedure provided unilateral ureteral obstruction (left kidney) to urinary flow and posteriorly was evaluated by -DTPA renal scintigraphy and histopathological study. -DTPA renal study was performed to detect and quantify signs of obstruction and to evaluate renal function. Statistical analysis was performed through the Student -test with a significance level of . Results. Nine of the ten rabbits presented left renal unit obstruction and one nonobstructive on the -DTPA and histopathological studies. All the right renal units, which were not submitted to surgical procedure, were nonobstructed by the studies. There was a general agreement between scintigraphy and histopathological results in both groups. Conclusion. The experimental model promoted the creation of ureteral obstruction in rabbits, confirmed by nuclear medicine scintigraphy and histopathology, and could be used in further studies to better understand urinary obstruction. 1. Introduction Pelvi-ureteric junction (PUJ) obstruction is one of the most frequent congenital anomalies of the urinary tract system. It is associated with pain, hydronephrosis, urinary tract infections, and eventually loss of renal function [1, 2]. It affects around 40% to 60% of all newborns with hydronephrosis [3], two times more common in males, and may be bilateral in 5% to 15% of cases [1, 4]. PUJ obstruction may be caused by intrinsic factors, like aperistaltic ureteral segment, obstructive fold mucosa, ureteral polyp, or ureteral stenosis [5]. Among extrinsic factors stands inferior renal polar vessel crossing anteriorly the PUJ [6]. Treatment varies from clinical observation to surgery. There are some surgical modalities available to correct the PUJ obstruction, differing from the open pyeloplasty to the latest in technology such as robotic assisted surgeries and endourological procedures [7–9]. Currently scientific literature is short in ureteral obstruction models that accurately reproduce the clinical and microscopic features of this infirmity [10–12]. The creation of a standardized experimental model that would be able to cause obstructive disturbance without leading to renal function loss would provide information capable of enhancing not only the diagnosis but
