(Journal of Applied Ichthyology, 2009-06-01) [Artigo]
Length-weight relationships were estimated for 20 species of the Jurumirim reservoir (southern Brazil): one Pimelodidae, one Callichthyidae, six Characidae, one Prochilodontidae, six Anastomidae, one Erythrinidae, two ...
Skeletal muscles with antagonistic muscular actions: morphological, contractile and metabolic characteristics
(International Journal of Morphology, 2009-12-01) [Artigo]
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 ...
Rendimento e composição química do filé de prochilodus lineatus do rio mogi guaçu, Brasil
(Archivos de Zootecnia, 2009-10-27) [Artigo]
The curimbata constitutes species of fish of wide distribution in the Neotropical area and high economic value. This work focused to evaluate processing yield and the chemical composition of the fillet in the male and ...
Alterações reprodutivas em ratos machos expostos perinatalmente aos frutos da Solanum lycocarpum
(Brazilian Journal of Veterinary Research and Animal Science, 2009-12-01) [Artigo]
This work employed pregnant rats treated with Solanum lycocarpum unripe fruits (10% in diet) from gestation day (GD) 06 to post-natal day (PND) 07, for the evaluation of the sperm number, daily sperm production and epididymal ...
Screening for In Vitro and In Vivo Antitumor Activities of the Mushroom Agaricus Blazei
(Nutrition and Cancer-an International Journal, 2009-01-01) [Artigo]
We have investigated the in vitro antitumor activity of the mushroom Agaricus blazei Murill on human cancer cell lines as well as its potential anticancer activity in a model of rat colon carcinogenesis. The in vitro ...
Relationship between Mast Cells and the Colitis with Relapse Induced by Trinitrobenzesulphonic Acid in Wistar Rats
(Mediators of Inflammation, 2009-01-01) [Artigo]
The present study aimed to clarify the role of mast cells in colitis with relapse induced in Wistar rats by trinitrobenzenosulphonic acid. Colitis induction increased the histamine concentration in the colon, which peaked ...
Differential MMP-2 and MMP-9 Activity and Collagen Distribution in Skeletal Muscle from pacu (Piaractus mesopotamicus) During Juvenile and Adult Growth Phases
(Anatomical Record-advances In Integrative Anatomy and Evolutionary Biology, 2009-03-01) [Artigo]
Here, we evaluated collagen distribution and matrix metalloproteinases (MMPs) MMP-2 and MMP-9 activities in skeletal muscle of pacu (Piaractus mesopotamicus) during juvenile and adult growth phases. Muscle samples from ...
Cytogenetic characterization of Eurysternus caribaeus (Coleoptera: Scarabaeidae): evidence of sex-autosome fusion and diploid number reduction prior to species dispersion
(Journal of Genetics, 2009-08-01) [Artigo]
Mitotic and meiotic chromosomes of several populations of Eurysternus caribaeus (Coleoptera: Scarabaeidae) were analysed through conventional staining, C-banding, base-specific fluorochromes, silver nitrate staining and ...
Comparative cytogenetics of cichlid fishes through genomic in-situ hybridization (GISH) with emphasis on Oreochromis niloticus
(Chromosome Research, 2009-08-01) [Artigo]
Cichlidae is the most species-rich freshwater family of Perciformes and has attracted the attention of aquarium hobbyists, aquaculturists, and sport fisherman. Oreochromis niloticus is very important in aquaculture today ...
