The aim of this research was to investigate the effect of testosterone propionate administration in the liver of rats. The rats were divided in the following groups: Initial control (SC), Aged control (SE) and Anabolic group (SA). Testosterone propionate was administered three times per week during 16 weeks. Using morphoquantitative techniques, we quantified the volume densities of lobular and non-lobular parenchyma, area and number of nuclei of hepatocytes. The data were analyzed statistically using mean and standard deviation, ANOVA one-way and level of significance about p0.05. Our results showed an increase in capillaries, perisinusoidal spaces and biliary ducts in SE group compared to SC. SA group showed a decrease in hepatic cells, non-lobular volume... |

The structural changes and morphological derivatives of progressive dentin hypermineralization determine the bonding to its surface. A planimetric study and fracture volume estimate were conducted to assess the efficacy of resin composite bonded to hypermineralized cervical dentin with and without retentions by applying a shear test. Thirty-four premolars from adult patients were used to obtain a flat cervical dentin surface. The specimens were distributed randomly into two groups: 1) experimental, where hemispherical retentions were carved into the cervical dentin, and 2) control, where the flat dentin was maintained. Using a jig, a resin column was built into the dentin surface fitted with bonding in specimens from both groups, which were then subjected... |

The term Podencos refers to a group of dog breeds from Spain and classification in Group 5 of dog breeds by the Fédération Cynologique Internationale (FCI). The aim of this study was to compare traits morphometric breeds of Podencos; Canario, Ibecenco, Andaluz (small, medium and large) and Orito. Ten morphometric variables were measured in 385 animals (245 females and 140 males), head length, muzzle length, height at withers, rump height, body length, head width, rump width, chest depth, chest girth and the shin circumference. Morphostructural variables were more homogeneous in the Podenco Ibicenco and the Podengo Canario, because for many years there were gradually distinctive trait standards for each breed. The discriminate analysis indicated... |

Soleus and tibialis anterior muscle EMG and soleus H-reflex are widely used to study ankle motor control during gait. Normally, the soleus H-reflex amplitude and EMG activity varies greatly through the course of walking. The examining of these events during walking requires space and resources that are generally found only in research oriented facilities, making difficult a more practical use. Earlier reports have suggested that normal variation of the soleus H-reflex and EMG could be determined from standing postures. Therefore, the main purpose of this study was to examine and determine which standing postures would reproduce the normal neuromotor variation of the ankle muscle antagonists. A total of five postures were investigated. The results of this... |

The purpose of this study was to evaluate and compare the soleus H-reflex amplitudes recorded in three standing postures between a group of patients with stroke and a group of healthy subjects. Nine ambulatory patients were compared with 10 healthy subjects. Measures were recorded during quiet standing (QS), heels raised (PO) and with the foot of the measured leg held just off the ground while standing on the opposite leg (SW). The results showed that patients, as opposed to the healthy group, did not inhibit soleus H-reflex in the SW posture. As opposed to evaluating ankle motor control during gait, the PO and SW standing postures appeared to offer a practical and objective method to assess soleus H-reflex when the purpose is to determine impairment (or... |

The histology and the ultrastructure of the uterine glands of the lesser bushbaby (Galago senegalensis) were studied in six specimens (5 pregnant and one non pregnant) which were fixed partly with bouin's fixative and part with 2.5% glutaraldehyde in 0.1 M cacodylate buffer. An overview of the main results revealed uterine glands in the non-pregnant uterus are rudimentary and scarce within the mucosa. In early pregnancy (first trimester) the uterine glands profiles appear in clusters. In late stage pregnancy (third trimester) the uterine gland profiles appear opposite chorionic vesicles. In the later stages of gestation maternal glandular epithelium consisted mainly of simple columnar epithelium. The cells had abundant flattened cisternae of granular... |

El propósito de este estudio fue evaluar la evidencia en relación al empleo de técnicas reconstructivas en el área cráneo-facial asociado el uso de células troncales en humanos. Se realizó una revisión sistemática de la literatura en las bases Medline, ScienceDirect, EMBASE, TripDatabase, LILACS entre marzo del 2004 a marzo del 2016 con criterios de elegibilidad y estrategia de búsqueda definida. La selección de artículos fue realizada por dos investigadores de forma independiente y cuando ellos presentaron discordancia, un tercer investigador realizó le selección. Se encontraron un total de 382 artículos, se realizó una selección de artículos, eliminado duplicados, estudios experimentales en animales y selección según análisis de resúmenes, se... |
