Forensic identification of the guitarfish species Rhinobatos horkelli, R-percellens and Zapteryx brevirostris using multiplex-PCR
(Molecular Ecology Resources, 2010-01-01) [Resumo]
Rhinobatos percellens, Rhinobatos horkelli and Zapteryx brevirostris, known as guitarfish, are commonly found inshore and caught by trawl nets. Recently, these species have been suffering sharp population declines. One of ...
Antiulcerogenic activity and toxicity of bauhinia holophylla hydroalcoholic extract
(Evidence-based Complementary And Alternative Medicine, 2015-01-01) [Artigo]
Several species of Bauhinia are used in traditional medicine for the treatment of gastrointestinal diseases, diabetes, and inflammation, among other conditions. The aim of this study was to investigate the antiulcer effect ...
Identification of the shark species Rhizoprionodon lalandii and R-porosus (Elasmobranchii, Carcharhinidae) by multiplex PCR and PCR-RFLP techniques
(Molecular Ecology Resources, 2009-05-01) [Artigo]
Rhizoprionodon lalandii and R. porosus are widely distributed along the Atlantic coast of the Americas, living close to coastal areas and therefore frequently captured by seaboard fisheries. However, morphological ...
Inflammatory reaction to the human bot-fly, Dermatobia hominis, in infested and reinfested mice
(Medical and Veterinary Entomology, 2003-03-01) [Artigo]
Two groups of mice were infested with first stage larvae of the human bot-fly, Dermatobia hominis (Linnaeus Jr) (Diptera: Oestridae). In the first group, skin biopsies were carried out 1, 3, 5, 7, 10 and 18 days after ...
Molecular identification of hybrids between Neotropical catfish species Pseudoplatystoma corruscans and Pseudoplatystoma reticulatum
(Aquaculture Research, 2011-11-01) [Artigo]
Cytogenetic analysis of B chromosomes in one population of the fish Moenkhausia sanctaefilomenae (Steindachner, 1907) (Teleostei, Characiformes)
(Comparative Cytogenetics, 2012-01-01) [Artigo]
The aim of this study was to characterize cytogenetically one population of the fish Moenkhausia sanctaefilomenae (Steindachner, 1907), with emphasis on the analysis of B chromosomes. The nucleolar activity in the B ...
Repetitive DNA probe linked to sex chromosomes in hybrids between Neotropical fish Leporinus macrocephalus and Leporinus elongatus (Characiformes, Anostomidae)
(Cytogenetic and Genome Research, 2009-01-01) [Artigo]
Interspecific hybrids of fish can offer important advances in the zootechnical exploration of this animal group. However, hybrids can pose serious biological risks to the environment and natural populations, making genetic ...
Genetic markers for the identification of hybrids among catfish species of the family Pimelodidae
(Journal of Applied Ichthyology, 2013-06-01) [Artigo]
Fish hybrids provide genetically manipulated products of excellent value for the commercial aquaculture industry. However, if handled or marketed incorrectly, they can cause great financial loss to producers as well as ...
Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)
(PLOS ONE, 2014-04-15) [Artigo]
Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic ...
Morphological studies on the heart ventricle of African catfish (Clarias gariepinus)
(Anatomia Histologia Embryologia-Journal of Veterinary Medicine Series C, 2002-08-01) [Artigo]
The histological and ultrastructural characteristics of the heart ventricle in Clarias gariepinus (African catfish) has been studied by light microscopy and transmission electron microscopy. The ventricle of the heart has ...
