Supernumerary chromosomes in the pufferfish Sphoeroides spengleri: first occurrence in marine Teleostean Tetraodontiformes fish
(Genetics and Molecular Biology, 2008-01-01) [Artigo]
Cytogenetic analyses carried out in eight specimens of Sphoeroides spengleri revealed the presence of 2n = 46 chromosomes (20 M/SM and 26 ST/A). Besides the standard karyotypical set, the presence of B microchromosomes was ...
Influence of Tumour Condition on the Macrophage Activity in Candida albicans Infection
(Scandinavian Journal of Immunology, 2009-07-01) [Artigo]
To better understand the interactions between opportunistic fungi and their hosts, we investigated hydrogen peroxide (H(2)O(2)), nitric oxide and TNF-alpha production by peritoneal macrophages from Ehrlich tumour-bearing ...
Reproduction and recruitment of the South American red shrimp, Pleoticus muelleri (Crustacea : Solenoceridae), from the Southeastern coast of Brazil
(Marine Biology Research, 2008-01-01) [Artigo]
Critical stock conditions for shrimps commonly exploited in southeastern Brazil have resulted in the targeting of other shrimp species such as Pleoticus muelleri. Descriptions of reproductive biology in penaeid species are ...
In vivo assessment of DNA damage and protective effects of extracts from Miconia species using the comet assay and micronucleus test
(Mutagenesis, 2008-11-01) [Artigo]
The genus Miconia comprises similar to 1000 species belonging to the Melastomataceae family. Several crude plant extracts from Miconia and their isolated compounds have shown biological activities, such as analgesic and ...
Growth and physiological responses of sunflower plants exposed to ultraviolet-B radiation
(Ciência Rural, 2007-02-01) [Artigo]

Modulation of macrophage cytokine profiles during solid tumor progression: susceptibility to Candida albicans infection
(BMC Infectious Diseases, 2009-06-12) [Artigo]
Background: In order to attain a better understanding of the interactions between opportunist fungi and their hosts, we investigated the cytokine profile associated with the inflammatory response to Candida albicans infection ...
Production of Trichophyton mentagrophytes antigens and their characterization in mice
(Journal of Venomous Animals and Toxins Including Tropical Diseases, 2008-01-01) [Artigo]
The participation of dermatophytic antigens in the host-parasite balance is still poorly understood. One of the difficulties encountered by researchers is the lack of dominant and specific antigens that can be used in such ...
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 ...
