Nucleotide sequence of 5S rDNA and localization of the ribosomal RNA genes to metaphase chromosomes of the Tilapiine cichlid fish, Oreochromis niloticus
(Hereditas, 2000-12-01) [Artigo]
In this study, we report the cloning and nucleotide sequence of PCR-generated 5S rDNA from the Tilapiine cichlid fish, Oreochromis niloticus. Two types of 5S rDNA were detected that differed by insertions and/or deletions ...
Molecular and cytogenetic analysis of the telomeric (TTAGGG)n repetitive sequences in the Nile tilapia, Oreochromis niloticus (Teleostei: Cichlidae)
(Chromosoma, 2002-03-01) [Artigo]
The majority of chromosomes in Oreochromis niloticus, as with most fish karyotyped to date, cannot be individually identified owing to their small size. As a first step in establishing a physical map for this important ...
Intestinal anti-inflammatory activity of coumarin and 4-hydroxycoumarin in the trinitrobenzenesulphonic acid model of rat colitis
(Biological and Pharmaceutical Bulletin, 2008-07-01) [Artigo]
Coumarins represent an important class of phenolic compounds with multiple biological activities, including inhibition of lipidic peroxidation and neutrophil-dependent anion superoxide generation, anti-inflammatory and ...
Tissue inhibitor of metalloproteinase-2 (TIMP-2) location in the ventral, lateral, dorsal and anterior lobes of rat prostate by immunohistochemistry
(Cell Biology International, 2007-03-01) [Artigo]
Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play a major role in extracellular matrix component degradation in several normal and abnormal tissue situations; they are also found in human seminal ...
Dietary restriction and fibre supplementation: Oxidative stress and metabolic shifting for cardiac health
(Canadian Journal of Physiology and Pharmacology, 2003-11-01) [Artigo]
Dietary modification ought to be the first line of strategy in prevention of the development of cardiac disease. The purpose of this study was to investigate whether dietary restriction, dietary-fibre-enriched diet, and ...
Composição e abundância da ictiofauna na zona litorânea de um tributário, na zona de sua desembocadura no reservatório de Jurumirim, Estado de São Paulo, Brasil
(Acta Scientiarum: Biological Sciences, 2003-01-01) [Artigo]
Monthly collections of fishes using a trawl net were carried out from August 1996 to December 1997 with the objective of evaluating the composition and diversity of fish species in the littoral area of the transition zone ...
Doxazosin reduces cell proliferation and increases collagen fibers in rat prostatic lobes
(Cell and Tissue Research, 2008-04-01) [Artigo]
We investigated the effects of doxazosin (Dox), an alpha-adrenoceptor antagonist used clinically for the treatment of benign prostatic hyperplasia (BPH), on the rat prostatic complex by assessing structural parameters, ...
Localization of myosin-Va in subpopulations of cells in rat endocrine organs
(Cell and Tissue Research, 2008-08-01) [Artigo]
Myosin-Va is a Ca 2+/calmodulin-regulated unconventional myosin involved in the transport of vesicles, membranous organelles, and macromolecular complexes composed of proteins and mRNA. The cellular localization of myosin-Va ...
Genetic vaccine for tuberculosis (pVAXhsp65) primes neonate mice for a strong immune response at the adult stage
(Genetic Vaccines and Therapy, 2007-11-29) [Artigo]
Background: Vaccination of neonates is generally difficult due to the immaturity of the immune system and consequent higher susceptibility to tolerance induction. Genetic immunization has been described as an alternative ...
The thrombocyte aggregation process in the turtle Phrynopys hilarii (Chelonia). An ultrastructural study
(Journal of Submicroscopic Cytology and Pathology, 2002-07-01) [Artigo]
This study investigates the thrombocyte aggregation process in the South American fresh water turtle (Phrynopys hilarii) using electron microscopy. Blood was taken from surgically exposed lateral neck vessels often turtles ...
