Evaluation of antiulcer activity of the main phenolic acids found in Brazilian Green Propolis.
TLDR
The results of this study show that caffeic, ferulic, p-coumaric and cinnamic acids display antiulcer activity.
Nerolidol, an Antiulcer Constituent from the Essential Oil of Baccharis dracunculifolia DC (Asteraceae)
TLDR
Nerolidol displays antiulcer activity, as it significantly inhibited the formation of ulcers induced in different animal models, however, further pharmacological and toxicological investigations are required to allow the use of nerolidol for the treatment of gastric ulcer.
Sympatric occurrence of two cytotypes of Astyanax scabripinnis (Characiformes, Characidae)
TLDR
Robertsonian translocations and an increase or loss of heterochromatin are proposed to explain the karyotypic divergence observed and some aspects related to the chromosome evolution of Astyanax scabripinnis are discussed.
Occurrence of macro B chromosomes in Astyanax scabripinnis paranae (Pisces, Characiformes, Characidae)
TLDR
Cytogenetic analysis of 27 specimens of Astyanax scabripinnis paranae from the Araquá river shows that this population has 2n=50 chromosomes, and the extra chromosome was a large metacentric similar in size and morphology to the first chromosome pair in the karotype.
Evaluation of the genotoxicity of Euterpe oleraceae Mart. (Arecaceae) fruit oil (açaí), in mammalian cells in vivo.
TLDR
Results indicate that, under experimental conditions, E. oleracea fruit oil did not reveal genetic toxicity in rat cells, and both cytogenetic tests performed showed that EOO presented no significant genotoxic effects in the analyzed cells, at the three tested doses.
Evaluation of the genotoxic potential of the Casearia sylvestris extract on HTC and V79 cells by the comet assay.
TLDR
The results showed that the extract of C. sylvestris presented no genotoxic effects and not modified effect inducing DNA damage by alkylating agents cyclophosphamide and methyl methanesulfonate in HTC and V 79 cells respectively.
First in vivo evaluation of the mutagenic effect of Brazilian green propolis by comet assay and micronucleus test.
TLDR
The acute consumption of green propolis produced some mutagenic effects on the blood cells of mice, and the polychromatic:normochromatic erythrocytes ratio was not statistically different from the negative control.
Unusual occurrence of a ZZ/ZW sex-chromosome system and supernumerary chromosomes in Characidium cf. fasciatum (Pisces, Characiformes, Characidiinae)
TLDR
The occurrence of one totally heterochromatic submetacentric chromosome restricted to females and considered as an unusual feature in fish karyotypes led to the identification of a ZZ/ZW sex-chromosome system.
Cytogenetic Analysis of A- and B-Chromosomes of Prochilodus Lineatus (Teleostei, Prochilodontidae) Using Different Restriction Enzyme Banding and Staining Methods
TLDR
It is concluded that the combined use of the above techniques can contribute to the correct identification of chromosomes and the karyotypic analysis in fishes.
Genotoxicity testing of Ambelania occidentalis (Apocynaceae) leaf extract in vivo.
TLDR
The hydro-alcoholic extracts of A. occidentalis had no mutagenic or cytotoxic effects in the mouse cells, and the ratio of polychromatic/normochromatic erythrocytes was scored for cytotoxicity assessment.
