1. DETERMINAÇÃO DE MERCÚRIO EM FÍGADO DE TETRÁPODES MARINHOS POR ESPECTROMETRIA DE FLUORESCÊNCIA ATÔMICA ACOPLADA A GERAÇÃO DE VAPOR FRIO (CV-AFS) E ESPECTROMETRIA DE MASSA COM FONTE DE PLASMA INDUTIVAMENTE ACOPLADO (ICP-MS): UMA COMPARAÇÃO SISTEMÁTICA ENTRE AS DUAS TÉCNICAS
This study compares the techniques cold vapour atomic fluorescence spectrometry (CV-AFS) and inductively coupled plasma mass spectrometry (ICP-MS) for the determination of Hg in biological samples (hepatic tissue from marine tetrapods). Acid digestions were performed for the samples and aliquots of them were analysed by ICP-MS and CV-AFS. To minimize the Hg

4. Molecular cloning, characterization and expression analysis of a novel PDRG1 gene from black tiger shrimp (Penaeus monodon)
Abstract P53 And DNA Damage-Regulated Gene 1 (PDRG1) is a novel gene which plays an important role in chaperone-mediated protein folding. In the present study, the full-length complementary DNA (cDNA) sequence of the PDRG1 gene from Penaeus monodon (PmPDRG1) was cloned by the rapid amplification of cDNA ends (RACE) method. The cDNA of PmPDRG1 spans 1,613 bp,

5. Solid Phase Extraction to On-Line Preconcentrate Trace Cadmium Using Chemically Modified Nano-Carbon Black with 3-Mercaptopropyltrimethoxysilane
Carbon black (CB) grafted with 3-mercaptopropyltrimethoxysilane (3-MPTMS) was used as solid phase extractor for Cd2+ in a flow injection system coupled to flame atomic absorption spectrometry (FAAS). The influence of pH, buffer concentration, preconcentration flow rate and eluent concentration on preconcentration of Cd2+ were investigated by means of chemome

6. Study of surface carbohydrates in Galba truncatula tissues before and after infection with Fasciola hepatica
The presence and distribution of surface carbohydrates in the tissues of Galba truncatula snails uninfected or after infection with Fasciola hepatica as well as on the surface of the snail-pathogenic larval stages of the parasite were studied by lectin labelling assay. This is an attempt to find similarities that indicate possible mimicry, utilised by the pa

7. Growth and reproduction of the mangrove crab Goniopsis cruentata (Latreille, 1803) (Crustacea: Decapoda: Grapsidae) in southeastern Brazil
Goniopsis cruentata é um caranguejo semi-terrestre comum em manguezais brasileiros e um importante recurso pesqueiro para comunidades tradicionais no nordeste do Brasil. Com o objetivo de contribuir com o conhecimento sobre a espécie, o presente estudo avaliou as curvas de crescimento em largura de carapaça e em peso, o crescimento relativo do peso pela l

8. Molecular cloning and mRNA expression of the peptidoglycan recognition protein gene HcPGRP1 and its isoform HcPGRP1a from the freshwater mussel Hyriopsis cumingi
Peptidoglycan recognition proteins (PGRPs) are innate immune molecules that have been structurally conserved throughout evolution in invertebrates and vertebrates. In this study, peptidoglycan recognition protein HcPGRP1 and its isoform HcPGRP1a were identified in the freshwater mussel Hyriopsis cumingii. The full-length cDNAs of HcPGRP1 (973 bp) and HcPGRP1

9. Caracterização citoquímica de células de brânquias e hepatopâncreas de Ucides cordatus (Crustacea, Brachyura) validado por transporte celular de metais
Ucides cordatus (Linnaeus, 1763) é um caranguejo de mangue hiper-hipo-regulador que possui brânquias responsáveis por processos respiratórios e osmorregulatórios. Apresentam também hepatopâncreas, que realizam digestão, absorção de nutrientes e detoxificação de metais tóxicos. Cada um desses órgãos possui células específicas que são importa

10. Validation of reference genes for RT-qPCR analysis of CYP4T expression in crucian carp
Reference genes are commonly used for normalization of target gene expression during RT-qPCR analysis. However, no housekeeping genes or reference genes have been identified to be stable across different tissue types or under different experimental conditions. To identify the most suitable reference genes for RT-qPCR analysis of target gene expression in the

11. Characterization and expression analysis of chymotrypsin after bacterial challenge in the mud crab, Scylla paramamosain
Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal

12. Development of the male reproductive system in Callinectes ornatus Ordway, 1863 (Brachyura: Portunidae)
This study describes the histology and histochemistry of the male reproductive system in Callinectes ornatus, comparing juvenile and adult developmental stages. We also analyzed changes in the gonadosomatic (GSI) and hepatosomatic (HSI) indices, and the weights of the testis and vas deferens during the development. The results showed that all stages, beginni
