| This study investigated the immunodetection of PTCH in epithelial components of dental follicles associated with impacted third molars without radiographic signs of pathosis. One hundred and five specimens of dental follicles associated with impacted third molars with incomplete rhizogenesis (between Nolla's stage 6 and 9) were surgically removed from 56 patients. Epithelial cell proliferation was determined by using immunohistochemical labeling. Statistical analysis was performed using Fisher exact test and a level of significance of 5%. Of the 105 dental follicles collected, 3 were PTCH-positive. The specimens with squamous metaplasia and epithelial hyperplasia had higher rates of positivity for PTCH, as well as those with active remnants of odontogenic... |

| The aim of our study was to verify the prevalence of the sternal foramen in adult cadavers and dry bones, as well as to determine its exact localization and relation to acupuncture points. One hundred eighty sternums fixed and contained in 10% formaldehyde solution were examined, of which 100 were dry bones and 80 belonged to adult cadavers. The morphometric measures were expressed in millimeters when measuring the length: 1) from jugular incision to the foramen (JI-F); 2) from sternal angle to the foramen (EA-F); 3) from xiphoid process to the foramen (XP-F). Statistical analysis was performed to compare expected vs obtained foramina frequency, using Fisher's test (p0.05 was considered significant). The results showed 16.6% sternal foramina, significant... |

| A toxic metal, cadmium (Cd), can accumulate in human organs. Placenta is usually used as indicator organ for Cd exposure. Therefore, we aim to investigate the different of placental morphology between the low- and high-Cd accumulated placentas. The samples were collected from 14 pregnant women who resided in low-Cd contaminated (L-Cd group) and high-Cd contaminated (H-Cd group) areas. The concentrations of Cd in blood (B-Cd), urine (U-Cd) and placentas (P-Cd) were measured by ICP-MS and AAS. The morphological appearance of placentas was examined by using routine paraffin section and H & E staining. The results showed that levels of B-Cd, U-Cd and P-Cd were significantly higher in H-Cd group than in L-Cd group (p= 0.001). Moreover, the B-Cd was... |

| La reacción y reparación dentinaria depende del número de odontoblastos. Los métodos para obtener estimaciones fiables sobre la cantidad de odontoblastos en la pulpa dental han sido subjetivos y sesgados, sobre todo al evaluar los cambios cuantitativos y la potencial capacidad reparativa en presencia de caries. El objetivo de este trabajo fue estimar y comparar cuantitativamente el número, densidad y volumen de odontoblastos en dientes sanos y con diagnóstico de pulpitis reversible producto de caries a través de herramientas estereológicas. Se utilizaron dientes premolares humanos obtenidos de exodoncias, divididos en un grupo sano y otro cariado. Fueron fijados y descalcificados con ácido nítrico al 5%. Siguiendo el protocolo del orientator se obtuvieron... |

| Durante un año, se estudió la próstata de individuos adultos de la especie Chinchilla laniger (MOLINA, 1982), mantenidos en cautiverio, para detectar posibles variaciones estacionales en el peso glandular y corporal, índice órgano-somático (IOS), grosor de la pared y altura del epitelio glandular y concentración de testosterona plasmática. Además, se realizó un análisis histoquímico con técnicas de PAS, diastasa-PAS y Azul de Alcian pH1 y pH 2,5. Se describió una Zona A, periférica y una Zona B, central. En ambas, las células epiteliales siempre fueron negativas al Azul de Alcian. En la Zona A, se detectó la presencia de glicoproteínas neutras con intensa reacción PAS (+++) entre octubre y abril y leve a moderada (+/++) entre mayo y septiembre, y ausencia... |

| Anatomical variations in the region of axilla and pectoral region are very common. These variations need attention to avoid complications arising during surgeries and diagnostic and interventional invasive procedures in this region such as surgeries for breast carcinoma, venous access during central venous line, pacemaker and cardiac defibrillator implantation etc. During routine cadaveric dissection we had noticed a rare variation of axillary vein and artery. In this case axillary vein, just deep to the inferior border of pectoralis minor was pierced by the lateral thoracic artery, a branch of axillary artery. Perforation of the axillary vein by a branch of the axillary artery is extremely rare variation encountered till now. We report a variation wherein... |

| The muscles can perform the same function in a specific segment (muscles of fast and slow contraction), and at the same time be antagonistic in relation to muscular action (flexors or extensors). The present research aimed to study the morphology, frequency and metabolism of fiber types and the contractile characteristics of extensor and flexors muscles of rabbit. We studied muscles anterior tibialis (AT), flexor digitorum supeficialis (FDS), extensor digitorum longus (EDL) and posterior tibialis (PT). The muscles were submitted to the techniques HE, NADH-TR and myofibrillar ATPase. In EDL and PT extensor muscles, the frequencies of red (SO + FOG) and white fibers (FG) were 68.77% and 31.23% versus 58.87% and 41.13%,... |

| La terapia láser AsGa es ampliamente utilizada en la rehabilitación de lesiones articulares y tendinosas. Por las características físicas del haz de luz utilizado, parte de esta irradiación es absorbida por tejido muscular adyacente, por lo que se planteó medir en un modelo experimental en rata, posibles efectos morfológicos de la irradiación láser AsGa en este tejido. Se realizó un estudio morfométrico y estereológico, utilizando ratas Sprague Dawley sanas, las que fueron irradiadas, por 10 días, en la zona del vientre del músculo gastrocnemio, utilizando tres diferentes dosis 0,8 (Al y A2), 2 (B) y 5 (C) joules/cm². Los miembros contralaterales no fueron irradiados (control). Se determinó el área de la fibra muscular por recuento de puntos (morfometría)... |

| The study has been conducted on the prenatal development of testis on 70 goat embryo/foeti, categorized into group-I (0-30 days), Group-II (31-60 days), Group-III (61-90 days), Group-IV (91-120 days) and group V (121days-till birth), having 14 embryos/ foeti in each group. The genital ridge was observed at 23 days of gestation. It contained an accumulation of mesenchymal cells, immature RBC's, differentiating fibroblasts and primordial germ cells. The formation of sex cords was evidenced on 44th day of gestation. It contained small mesenchymal cells and large cells arranged in a chain like manner. The convolution of the sex cords started between 61-90 days of gestation, which increased with the increase in the gestation period and at 125 day of gestation... |

| This study assesses the quality, as a diagnostic test, of the main indicators of morphological sexual dimorphism through direct anthropometry, biostatistics tools and clinical epidemiology. This study used 284 skulls of adult Brazilians, of which 187 were male and 97 female. A study of the cross-evaluation of the diagnostic test was performed; it was a qualitative approach based on visual examination of 16 traditional indicators of morphological sexual dimorphism, where each indicator determined the level of accuracy, sensitivity, predictive values, likelihood ratios, and odds ratio. All indicators studied had high levels of accuracy (84.7572.89%). The best indicators were found in traits whose formation is related to the insertion and action of major... |

| The study is associated with the effect of aspirin (Acetyl Salicylic Acid) on the microhardness of mineralized tissues of the offspring's teeth, in response to the ingestion of the drug during pregnancy. Aspirin is a widely used analgesic and antipyretic medicine, for symptomatic treatment. Misuse of this drug during pregnancy may instigate developmental defects in offspring. An experimental control study was designed, in which female rabbits were taken as representative mammalian models and treated with aspirin during pregnancy. Their offspring's teeth were used to assess the microhardness of dental tissues. The rabbits were alienated into two groups, treated and control, consisting of seven rabbits in each set (n= 7). Microhardness was evaluated in three... |
