Many elderly patients have concomitant anorectal, urological and gynecological symptoms involving multiple perineal structures, which require the surgeon to operate in different areas of his specialty in order to correct different dystopias in a single procedure. We describe a technique for total rectal ...
Há interesse mundial no desenvolvimento de pesquisas envolvendo produção e extração de colorantes naturais, devido a sérios problemas de segurança industrial associados ao uso de colorantes sintéticos. Este trabalho objetivou produzir colorantes naturais de Penicillium purpurogenum DPUA 1275 por ...

The aim of our research was to create an osteogenic unit in the skulls of athymic mice; however, the first challenge we faced was to find sufficient and adequate data that would allow us to determine the morphological, immunohistochemical and microtopographical characteristics that could be used as norma...
En peces, el nervio óptico es el encargado de transportar la información integrada por las células ganglionares de la retina hacia el tectum óptico, para que se generen imágenes acerca del entorno. El objetivo de este trabajo es describir morfométricamente el nervio óptico del tiburoncito (Ariopsi...
The mosquito midgut is the organ into which the blood meal passes and in which, within a peritrophic membrane secreted by the epithelium, the blood is retained during digestion and absorption. The mosquito midgut is lined with an actin filled microvilli that are exposed to the harsh environment of the gu...

El presente estudio pretende describir el somatotipo del futbolista profesional chileno, así como determinar la variabilidad existente en el somatotipo por posición de juego. Cien jugadores profesionales varones (edad 23±4,4 años), participantes del campeonato nacional de fútbol chileno fueron inclu...
The aim of this study was to radiographically investigate the curve existing in slightly curved mesiobuccal canal of mandibular first molar by applying Piecewise straight line approximation. Extracted human mandibular molars were radiographed and one hundred radiographs were selected whose mesiobuccal ca...
The tissue microarrays (TMAs) were first called multitumor block. In 1998 was described the current technique, that uses an innovated sampling method for more than 1,000 cylindrical paraffin tissue core biopsies in a single paraffin block. TMAs are now considered as a useful powerful research tool in His...
Abnormal interaction between oral epithelium and underlying mesenchematic tissue during odontogenesis could result in teeth with an anatomical variation. First maxilar premolar has such variable root canal morphology. However, (0.2-6% of cases) a three-rooted premolar is particularly uncommon. First mand...
