Fluorescence in situ hybridization with rDNA probes on chromosomes of two nucleolus organizer region phenotypes of a species of Eigenmannia (Pisces, Gymnotoidei, Sternopygidae)
(Chromosome Research, 1996-07-27) [Artigo]
Nucleolus organizer regions (NORs) were analysed in two related and geographically close populations of Eigenmannia sp.1 (Pisces, Gymnotoidei, Sternopygidae) using silver staining and fluorescence in situ hybridization ...
Does the male reproductive performance depend on the early lactation milk in rats?
(Physiology and Behavior, 1996-01-01) [Artigo]
This study investigated the role of the early lactation milk (ELM) on the male reproductive performance and the participation of GnRH on this effect in Wistar rats. Newborn males were divided into three experimental groups: ...
Histochemical study of muscle fiber types in Synbranchus marmoratus Bloch, 1795
(Annals of Anatomy, 1996-01-01) [Artigo]
The myotomal muscle of Synbranchus marmoratus was investigated using histochemical and immunohistochemical reactions. This musculature is composed of a superficial red compartment, uniformly distributed around the trunk ...
Inside-out vs. standard vein graft to repair a sensory nerve in rats
(Anatomical Record, 1999-11-09) [Artigo]
Nerve regeneration in a sensory nerve was obtained by the application of different techniques: inside-out vein graft (IOVG group) and standard vein graft (SVG group). These techniques provide a good microenvironment for ...
Tracheobronchial consequences of the use of heat and moisture exchangers in dogs
(Canadian Journal of Anaesthesia, 1999-11-22) [Artigo]
Purpose: To determine the effect of heat and moisture exchange (HME) on the tracheobronchial tree (TBT) using a unidirectional anesthesic circuit with or without CO2 absorber and high or low fresh gas flow (FGF), in dogs. ...
Ultrastructural and morphometric aspects of ageing in the retinal capillaries of rats
(Journal of Submicroscopic Cytology and Pathology, 1997-04-01) [Artigo]
Age-related morphological, ultrastructural and morphometric changes in the capillaries of the superficial and deep plexuses of the rat retina were studied in animals aged from 3 to 15 months. Our results suggest that ...
