Abstract: El nervio isquiático, ramo del plexo sacro, abandona la pelvis pasando, generalmente, por debajo del músculo piriforme. Este nervio puede presentar variaciones en su relación con el músculo piriforme, entre ellas, las referidas a la división alta. Sin embargo, son pocos los trabajos que correlacionan esta división con variaciones anatómicas y su relación con el músculo piriforme, en fetos humanos. Con el propósito de verificar una posible asociación entre el trayecto y relaciones de ramos del nervio isquiático, fueron disecadas 100 regiones glúteas de fetos humanos. Se encontraron 3 tipos de variaciones entre el nervio isquiático y el músculo piriforme: en 8 casos (16,0 %) el nervio fibular común pasó a través del músculo y el nervio tibial transcurrió por debajo de su margen inferior (Tipo I). En estos mismos casos se observó que 5 (62,5%) estaban a la izquierda y 3 a la derecha. En un caso (2,0 %), el nervio fibular común hizo su trayecto por sobre el margen superior del músculo piriforme y el nervio tibial pasó por debajo de su margen inferior (Tipo II). Fue observado en el Tipo III,que el nervio isquiático perfora el músculo piriforme, no presentando ninguna división. El músculo piriforme mostró variaciones de fusión con el músculo glúteo mediano (lado derecho =2,0%) y con el músculo gemelo superior (lado derecho =24,0% e izquierdo =32,0%). Estos datos muestran que existe una equivalencia de variacion entre los trayectos y relaciones del nervio isquiático con el músculo piriforme en fetos y adultos. Las variaciones en el músculo piriforme no están asociadas con alteraciones funcionales en la biomecánica de la pelvis. The sciatic nerve, branch of the sacral plexus, leaves the pelvis and passes usually below of the piriform muscle. The sciatic nerve also comes from this plexus and can have distinct relationships with the mentioned muscle, as the high division of the nerve. However, there are few studies that correlate that division with the course of the sciatic nerve and its relationship with the piriform muscle, as well as, variations of that muscle in human fetuse. In order to verify a possible association between those anatomical structures, we dissected 100 gluteal regions of human fetuses. Three types of variations were found between the sciatic nerve and the piriform muscle. The common fibular nerve pierced the muscle and the tibial nerve passed below of its inferior margin in 8 cases (16,0 %), corresponding to the type I. In these cases, we found 62,5% in right side and 37,5% in left side. The type II was observed in 1 case (2,0 %), the common

Abstract: The angular limb deformities may occur due to bone malformation, increasing levels of calcium in the diet, fracture with incomplete consolidation or premature closure of the distal physis of the long bones. The distal and proximal epiphysis of the radius grow at different rates of ulnar epiphyses, the ulnar interruption development, due to premature closure of epiphyseal lines, restricts the longitudinal growth of the radius, resulting in the development of an angular bone deformity called radius curvus. The treatment is surgical and consists in ulnar ostectomy associated with an autologous fat grafting and external fixator. This paper aims to report the effectiveness of treatment for radius curvus, emphasizing use of a surgical procedure which consists of the unconventional technique for radial and ulnar wedge ostectomy, associated with internal plates and screws fixation. As deformidades angulares dos membros podem ocorrer devido à malforma o óssea, dietas ricas em cálcio, consolida o inadequada de fraturas ou fechamento precoce das linhas epifisárias distais dos ossos longos. As epífises distal e proximal do rádio crescem em propor es diferentes das epífises ulnares, a interrup o do crescimento da ulna, devido ao fechamento precoce das linhas epifisárias, restringe o crescimento longitudinal do rádio, resultando no desenvolvimento de uma deformidade angular óssea denominada rádio curvo. O tratamento do rádio curvo é cirúrgico sendo que a técnica cirúrgica mais utilizada é a ostectomia ulnar associada a um enxerto de gordura autógena e fixador externo. Este trabalho tem como objetivo relatar a eficácia do tratamento para corre o do rádio curvo em um c o, enfatizando o uso de um procedimento cirúrgico pouco convencional que consiste na técnica de ostectomia ulnar e radial em cunha associada à osteossíntese com placas e parafusos.

Abstract: the meticulous physical examination is important as complementary to clinical observation and patient's history and needs the adequate knowledge of the human anatomy. therefore, the objective of this study was to evaluate the nurse students knowledge of topographical anatomy as a basis for the practice of physical examination. a questionnaire was used containing 11 objective questions on anatomy, which are important for the nurse professional practice. for this study, 176 volunteer students enrolled in clinical training were interviewed randomically. the test was applied to students of 6 differents groups (between 4th and 9th period).the data was analysed by contigency analysis (expected data vs obtained data) in the software graphpad instat, being used the exact statistical fisher's test with approach of katz and anova test. p was considered £ 0,05 as significant to determine the difference among the groups. the obtained answers compared individually with the expected ones, presented significant variations. a high index of incorrect answers was found in group a (4th period). after comparison among the groups, a decrease was verified in the proportional average of mistakes (37,9%) and of successes (35,7%) among the 4th period (group a) and the group f (9th period). in the individual analysis of the questions, lack of knowledge on some subjects was large, especially among the student's last clinical periods, where the occurrence of wrong answers was even larger. the data reveal that, the more the student advances in clinical training and the distance from anatomy, increases the less familiarity he or she presents with regard to this knowledge. the high index of mistakes and the variance of the data suggest a revision in the hourly load and curriculum of the course, because the students show difficulties in understanding the contents and the anatomical nomenclature.

Abstract: the sabellariid phragmatopoma caudata (kroyer, 1856), morch, 1863 is widely distributed in the americas and constructs large reef agglomerates that provide substrates for other benthic species. however, the difficulty in obtaining size data (especially length) hampers population studies, making it necessary to carry out morphometric studies as basis for studies of population dynamics. the objective of the present study is to determine the best morphological descriptor of length in p. caudata. a total of 17 morphometric variables were measured in specimens from four different populations. measurements were performed using an ocular micrometer attached to a stereoscopic microscope. correlations in the dataset were tested using pearson's linear correlation coefficient, and the hypothesis of morphometric differences among populations was tested using manova and principal component analysis. correlation coefficients were different amongst populations, as well as in the measured traits . moreover, the results suggest that populations differ more strongly in body size than in shape. although populations presented different morphometric relationships, the length of the first thoracic chaetiger was one of the variables with highest correlation with total length. this result, as well as the fact that such region is located on the anterior portion of the body, suggests that this structure is a good length descriptor in p. caudata.

Abstract: El examen físico minucioso es importante en la complementación de la observación clínica e historia del paciente y necesita del perfecto conocimiento de la anatomía humana. Por tanto, el objetivo de este estudio fue evaluar el conocimiento en Anatomía Topográfica de los estudiantes del ciclo clínico-hospitalario de Enfermería, para la práctica del examen físico. Fue utilizado un cuestionario, conteniendo 11 preguntas objetivas de Anatomía, importantes para la práctica profesional del Enfermero. A partir de la distribución total de alumnos matriculados en el ciclo clínico, fueron entrevistados aleatoriamente, 176 voluntarios que participaron del estudio. La prueba fue aplicada en alumnos de 6 grupos (A al G, equivalentes a los semestres 4o al 9o ). Los datos fueron evaluados por análisis de contingencia (datos esperados vs datos obtenidos) en el Software Graphpad Instat, utilizándose la prueba estadística exacta de FISHER con aproximación de KATZ y prueba de ANOVA. Fue considerado el p< 0,05 como significativo, para determinar la diferencia entre los grupos. Las respuestas obtenidas, comparadas con las esperadas individualmente, presentaron variaciones significativas. Ocurrió alto índice de respuestas incorrectas en el grupo A (4o semestre). Después de la comparación entre los grupos, se constató la disminución en la media proporcional de errores (37,9%) y de aciertos (35,7%) entre el 4o semestre (grupo A) y el 9o semestre (grupo F). En el análisis individual del cuestionario, el desconocimiento sobre algunos temas fue muy grande, especialmente en los alumnos de los últimos semestres clínicos, donde la ocurrencia de respuestas incorrectas fue mayor. Los datos revelan que, mientras más profundiza el alumno en los semestres clínicos, más se aleja de la Anatomía, presentando menor familiaridad con esos conocimientos. El alto índice de errores y la variedad de los datos hacen sugerir una revisión de la carga horaria y de la programación del currículo del curso, pues los alumnos apuntan dificultades en el entendimiento del contenido (aprendizaje) y de la Terminología Anatómica.

Abstract: La observación y manipulación del cadáver en las aulas de Anatomía, todavía son métodos que contribuyen de manera eficiente en la comprensión de la forma, espacio y distancia de las estructuras anatómicas. Sin embargo, el contacto con el cadáver parece provocar diferentes tipos de reacciones en los estudiantes. El objetivo de este trabajo fue identificar las reacciones de los alumnos del área de la Salud frente al primer contacto con el cadáver, en las aulas de trabajos prácticos de Anatomía. El estudio también analiza la influencia de esta actividad en el proceso de ense anza-aprendizaje de Anatomía. Al final del semestre lectivo, fueron entrevistados aleatoriamente 395 alumnos matriculados en los cursos del área de la Salud, que cursaron la disciplina de Anatomía teórica y práctica. La investigación se realizó en base a un cuestionario con preguntas abiertas y cerradas, referidas a sexo, edad, curso, interés por la disciplina y reacciones frente al contacto con el cadáver. El tratamiento estadístico de los datos fue realizado con el auxilio del software Graphpad Instat, siendo seleccionado el test Qi2, con un p<0.05 como significativo. Los estudiantes eran jóvenes y la mayoría, de sexo femenino. El 92,2% de los alumnos consideró "importante" y se interesó por el conocimiento del cuerpo humano, independientemente de la exigencia curricular. En la reacción al primer contacto con el cadáver, el 40,8% relató ningún recelo. Algunas reacciones fueron identificadas en el16,0% de los alumnos, como: miedo, náuseas, schock y recuerdos de familiares fallecidos. En cuanto a la "convivencia" con el cadáver, los alumnos revelaron una reacción académica, respetando su instrumento de estudio y que no sufren ninguna alteración en su quehacer cotidiano, con respecto a alimentación, sue o, etc. La consideración atribuida al estudio práctico en el cadáver, fue de "muy importante", y que la manipulación del mismo influye en el aprendizaje. Parece ocurrir una despersonalización del cadáver después de la disección, pues las reacciones frente al primer contacto, no fueron expresivas. Según los alumnos, el estudio práctico en el cadáver es imprescindible, pues materializa y corrige conceptos teóricos erróneos y/o variaciones sobre aspectos topográficos Theviewandhandlingofcorpseinanatomy′sclassesarestillmethodsthatcontributeinanaffecientway totheform,espaceanddistancecomprehensionofanatomic′sestructure.

Abstract:
The central importance of quantum chemistry is to obtain solutions of the Schr?dinger equation for the accurate determination of the properties of atomic and molecular systems that occurred from the calculation of wave functions accurate for many diatomic and polyatomic molecules, using Self Consistent Field method (SCF). The application of quantum chemical methods in the study and planning of bioactive compounds has become a common practice nowadays. From the point of view of planning it is important to note, when it comes to the use of molecular modeling, a collective term that refers to methods and theoretical modeling and computational techniques to mimic the behavior of molecules, not intend to reach a bioactive molecule simply through the use of computer programs. The choice of method for energy minimization depends on factors related to the size of the molecule, parameters of availability, stored data and computational resources. Molecular models generated by the computer are the result of mathematical equations that estimate the positions and properties of the electrons and nuclei, the calculations exploit experimentally, the characteristics of a structure, providing a new perspective on the molecule. In this work we show that studies of Highest Occupied Molecular Orbital Energy (HOMO), Low Unoccupied Molecular Orbital Energy (LUMO) and Map of molecular electrostatic potential (MEP) using Hatree-Fock method with different basis sets (HF/3-21G*, HF/3-21G**, HF/6-31G, HF/6-31G*, HF/6-31G** and HF/6-311G), that are of great importance in modern chemistry, biochemistry, molecular biology, and other fields of knowledge of health sciences. In order to obtain a significant correlation, it is essential that the descriptors are used appropriately. Thus, the quantum chemical calculations are an attractive source of new molecular descriptors that can, in principle, express all the geometrical and electronic properties of molecules and their interactions with biological receptor.
