(Olhar de Professor, 2011) [Artigo]
The acceleration of economic and scientific development caused by the production system and mechanistic science, have created new power structures and new political and social problems, including environmental ones, ...
Karyotypic conservatism in five species of Prochilodus (Characiformes, Prochilodontidae) disclosed by cytogenetic markers
(Genetics and Molecular Biology, 2013-09-05) [Artigo]
The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with ...
Chromosomal location of retrotransposable REX 1 in the genomes in five Prochilodus (Teleostei: Characiformes)
(Mobile Genetic Elements, 2013) [Artigo]
Transposable elements are repetitive DNA sequences comprising a group of segments able to move and carry sequences within the genome. Studies involving comparative genomics have revealed that most vertebrates have different ...
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 ...

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 ...
