| It is of paramount importance for surgeons to have a thorough knowledge of the normal anatomy of the extrahepatic bile ducts and its variations due to the high frequency with which they perform in this anatomic site. The cystohepatic triangle, or Calot's Triangle, is bound by the cystic duct, common hepatic duct, and the hepatic border; therefore, its surface area depends on the conformation of these ducts and is closely linked to surgical procedures performed in this region. It has been reported that the length and the position of these ducts may be related to the formation of bile duct stones, Mirizzi's syndrome, and bile duct cancer. Thus, the present work aims to analyze the configuration of the extrahepatic biliary tree and its possible variations, as... |

| The aim of this study was to accurately measure acromial morphology in order to describe the anatomical patterns of its subtypes and to conduct a survey of the literature regarding the relationships between morphological subtypes and their related diseases. We photographed scapulae from the Institute of Anatomy, University Severino Sombra, and analyzed the images using Image-J Software®. The average acromial angle was 139.23° ± 2.781, with no significant difference between the right and left sides. There was a positive correlation between the acromial angle and the angle of the spine of the scapula. The correlation mentioned above plays an important role in disorders of the shoulder-particularly impingement syndrome-which reinforces the importance of... |

| Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may... |

| El desarrollo dentario resulta de una complicada interacción entre el epitelio oral y el tejido mesenquimático subyacente durante la Odontogénesis. La interacción anormal de estos tejidos podría resultar en el desarrollo y/o erupción de un diente anómalo, ectópico o con variación anatómica. El presente reporte muestra tres casos de variaciones anatómicas radiculares y al sistema de canales: un canino mandibular, un premolar mandibular y un primer premolar maxilar. El diagnóstico en los tres casos se efectuó por medio del análisis de radiografías. El canino y premolar mandibular presentaron dos raíces y dos canales, el premolar maxilar presentó tres raíces y tres conductos. Dada la presencia de una caries penetrante en este último, fue derivado a un... |

| El Laboratorio de Plastinación de la Universidad de los Andes ha trabajado hasta hoy, exclusivamente la técnica en Silicona para preservar el material cadavérico mediante este tipo de conservación. Sin embargo, este método tiene algunas desventajas en cortes anatómicos finos. Se desarrolló un método de plastinación en resina poliéster, en base a la técnica ya protocolizada, adaptándolas a nuestro laboratorio, con el fin de obtener muestras con mayor resistencia y calidad, sin alterar las estructuras. Se utilizaron cortes anatómicos de segmentos distales de miembro inferior humano fijados en acetona a - 17 C y otros de encéfalo de vacuno fijados con formalina acuosa al 10% a 4 C, de un grosor que varía entre 0,4 y 0,8 cm. Se procedió a deshidratar las... |

| The purpose of the present study was to compare the platelet and fibrin network ultrastructure of humans to eight different animal species in order to determine the differences between human and animal platelet and fibrin morphology, and to determine whether the animals studied differ in their platelet and fibrin morphology, and whether these differences can be observed by scanning electron microscopy. Platelets and fibrin networks play an important role both in the coagulation process as well as physiologically in allergic processes and immunological mechanisms. The thickness of human fibrin networks were compared to mouse (Mus musculus), equine (Equus caballus), vervet monkey (Chlorocebus aethiops previously Cercopithecus aethiops), oryx (Oryx gazella),... |

| Las fallas de implantación son consideradas una importante causa de infertilidad en mujeres sometidas a protocolos de Fecundación Asistida. Evidencia reciente sugiere que la presencia de variantes protrombóticas está asociada a diversos defectos obstétricos y falla reproductiva. Sin embargo, los resultados en diversas poblaciones son contradictorios. De acuerdo a esta evidencia, se evaluó la potencial asociación entre variantes protrombóticas y fallas de implantación en mujeres chilenas incluidas en protocolos de fecundación asistida. Un total de 180 mujeres, 80 pacientes sometidas a protocolos de reproducción asistida y 100 controles fueron incluidas en este estudio. La genotipificación molecular de variantes protrombóticas en genes candidatos fue... |

| La anatomía humana tiene como importante fuente de estudio al cuerpo humano. Ella utiliza cuerpos no reclamados, usualmente de indigentes, cuerpos entregados como un beneficio a la sociedad sin nada pedir nada a cambio, siendo dignos de pleno respeto. Sin embargo, preocupa que la muerte no es mirada socialmente como algo natural a la vida, llevando la convivencia en el laboratorio de anatomía humana a un estado de miedo, angustia y repulsión. Con eso se produce un mecanismo de negación, que puede generar deshumanización hacia la pieza anatómica. Ser confrontado con la muerte de otro, es lo mismo que confrontarse con nuestra propia muerte. En este contexto, los profesores y técnicos tienen una gran responsabilidad en discutir y reflejar la cuestión, de modo... |

| Liver is the largest gland in the body and rarely shows variations in its lobes and fissures. We studied 55 Formalin-fixed livers for occurrence of abnormal shape, lobes, fissures and position of gall bladder. In 60% of cases the liver was normal. 40% livers showed one or the other variations. Additional lobes were found in 9.09% of cases. Additional fissure was found in 1.81% of cases. Presence of dumbbell shaped caudate lobe and presence of large papillary process was noted in 1.81% cases each. In 1.81% cases the fissure for ligamentum teres was absent or situated on the anterior surface of the liver. In 1.81% of cases each the liver was either extremely long or extremely flat. In 18.18% of the cases, the gall bladder was short and its fundus did not... |

| El conejo ha demostrado ser un excelente modelo de estudio de implantación. Como ovulador obligado, el tiempo de preñez se puede establecer en forma precisa. La observación morfológica de cortes de úteros de 7, 8, 9 y 10 días pos coito, permitió en este estudio reconstruir una secuencia de los eventos morfométricos que ocurren durante la implantación, en el conejo. Se utilizaron 20 conejas neozelandesas blancas adultas (Oryctolagus cuniculus), nulíparas, no gestantes. Para la cruza, se utilizaron 5 machos de probada fertilidad. Los conejos fueron obtenidos del Bioterio de la Facultad de Medicina de la Universidad de La Frontera, Temuco, Chile. Determinamos como día 0, el momento del coito, sacrificando las hembras los días 7, 8, 9 y 10 de cada cruza. Una... |

| A study was conducted to provide information on the skin weight of Pyrenean horses and to determine whether there is a measurement to predict this based on carcass weight. Hot carcass weight (HCW) and fresh skin weight (SW) were recorded for 58 horses aged 12 months entering a Catalan commercial slaughter facility between September 2009 and June 2010. Data on the breeder, age and coat characteristics were collected and subsequently collated for each animal. Prior to analysis, horses were subdivided into sex and coat groups. Data did not differ (P < 0.001) among these. The absence of differences in SW could be viewed as a reflection of limited nutritional differences between seasons. Regression procedures were used to develop equations to predict SW from... |

| Placenta is the most accurate record of the infant prenatal experience. After delivery if the placenta is examined minutely, it provides much insight into the prenatal health of the baby and the mother. In diabetic pregnancy, placental weight is higher in comparison to normal pregnancy. To study the cellular differences that might contribute to larger size of placenta, light microscopic analysis was performed on 25 full term placentas, out of which 20 were of Gestational diabetes mellitus (12 controlled on diet, 8 controlled on insulin) and 5 control group. Tissue sections were processed and analyzed. Birth weight of neonate, placental weight, vascular pattern of chorionic blood vessels and site of attachment of umbilical cord were recorded. In the... |

| Evidence supports the ethnic and sex variation in the form and position of the supraorbital foramen. Therefore, detailed knowledge of the population specific data on biometric features of the supraorbital foramen will facilitate diagnostic, local anesthetic and surgical manipulations in the maxillo-facial region. The goal of this study was to elucidate the morphological features and precise anatomical position of the supraorbital foramen with reference to surrounding surgically encountered anatomical landmarks in an adult Sri Lankan population. A total of one hundred and eight adult dry skulls of known sex were assessed to determine the number, shape, orientation, vertical and transverse diameters of the supraorbital foramen, transverse distance from the... |
