| assessment of trophic transfer of benzo(a)pyrene genotoxicity from the post-larval pink shrimp f. brasiliensis to the juvenile florida pompano t. carolinus. | in the present study, the polycyclic aromatic hydrocarbon (pah) genotoxicity was investigated in a one-step predator-prey relationship with the trophic-related marine species. florida pompanos were fed for 5 and 10 days with pink shrimp post larvae previously exposed to benzo(a)pyrene (bap) concentrations. parent bap body burden was measured in samples of farfantepenaeus brasiliensis. bap metabolites were determined in bile samples of trachinotus carolinus and dna damage was assessed through the ... | 2012 | 22974793 |
| molecular cloning of crustins from the hemocytes of brazilian penaeid shrimps. | crustins are antimicrobial peptides initially identified in the hemocytes of the crab carcinus maenas (11.5-kda peptide or carcinin) and recently also recognized in penaeid shrimps and other crustacean species. the aim of this study was to identify sequences encoding for crustins from the hemocytes of four brazilian penaeid species: farfantepenaeus paulensis, farfantepenaeus subtilis, farfantepenaeus brasiliensis and litopenaeus schmitti. using primers based on consensus nucleotide alignment of ... | 2007 | 17697082 |
| detection of pathogenic escherichia coli and microbiological quality of chilled shrimp sold in street markets. | foodborne illnesses caused by escherichia coli are one of the most important gastrointestinal diseases and therefore represent a public health risk. the presence of e. coli in water or in products such as shrimp indicates faecal contamination. however, indicator micro-organisms can be used to evaluate the microbiological quality of food sold in markets. this study focused on detecting isolates of e. coli containing the genes stx1a, stx2a, eae, lti, sta, stb, aggr and pcvd432 in chilled shrimp so ... | 2016 | 26960181 |
| the invasion of five alien species in the delta do parnaíba environmental protection area, northeastern brazil. | marine biological invasions have been regarded as one of the major causes of native biodiversity loss, with shipping and aquaculture being the leading contributors for the introductions of alien species in aquatic ecosystems. in the present study, five aquatic alien species (one mollusk, three crustaceans and one fish species) were detected during dives, shore searches and from the fisheries on the coast of the delta do parnaíba environmental protection area, in the states of piauí and maranhão, ... | 2010 | 20737846 |
| anticoagulant and antiprotease effects of a novel heparinlike compound from shrimp (penaeus brasiliensis) and its neutralization by heparinase i. | heparin is usually obtained from mammalian organs, such as beef lung, beef mucosa, porcine mucosa, and sheep intestinal mucosa. because of the increased use of heparin in the production of low-molecular-weight heparin (lmwh), there is a growing shortage of the raw material needed to produce lmwhs. a previous report described the structural features of a novel lmwh from the shrimp (penaeus brasiliensis). in order to compare anticoagulant and antiprotease effects of this heparin, global anticoagul ... | 2001 | 11190904 |
| structural features and anticoagulant activities of a novel natural low molecular weight heparin from the shrimp penaeus brasiliensis. | a natural low molecular weight heparin (8.5 kda), with an anticoagulant activity of 95 iu/mg by the usp assay, was isolated from the shrimp penaeus brasiliensis. the crustacean heparin was susceptible to both heparinase and heparitinase ii from flavobacterium heparinum forming tri- and di-sulfated disaccharides as the mammalian heparins. (13)c and (1)h nmr spectroscopy revealed that the shrimp heparin was enriched in both glucuronic and non-sulfated iduronic acid residues. the in vitro anticlott ... | 1999 | 10434045 |
| unique heparan sulfate from shrimp heads exhibits a strong inhibitory effect on infections by dengue virus and japanese encephalitis virus. | the structure and biological activities of a highly sulfated heparan sulfate (hs) extracted from shrimp (penaeus brasiliensis) heads were characterized. structurally the shrimp hs was more heterogenous than heparin, although it is still highly sulfated. the molecular mass of the shrimp hs preparation was determined to be 32.3kda by gel filtration hplc. analysis by surface plasmon resonance demonstrated that various growth/differentiation factors specifically bound to the shrimp hs with comparabl ... | 2011 | 21806963 |
| histochemical study of the hepatopancreas in adult females of the pink-shrimp farfantepenaeus brasiliensis latreille, 1817. | this study provides histochemical data of the hepatopancreatic cells of adult female pink-shrimp (farfantepenaeus brasiliensis) at two different developmental stages (those with developed gonads and those with exhausted gonads). the f. brasiliensis females were collected in seawater off the guarapari coast, espirito santo, brazil. five cell types were identified in this digestive gland: b (vesicular), e (embryonic), f (fibrillar), m (basal) and r (resorptive). the digestive gland was stained wit ... | 2014 | 23992941 |
| [ecophysiological adaptability of tropical water organisms to salinity changes]. | physiological response of tropical organisms to salinity changes was studied for some marine, estuarine and freshwater fishes (astyanax bimaculatus, petenia karussii, cyprinodon dearborni, and oreochromis mossambicus), marine and freshwater crustaceans (penaeus brasiliensis, penaeus schmitti and macrobrachium carcinus), and marine bivalves (perna perna, crassostrea rhizophorae, and arca zebra) collected from northeast venezuela. they were acclimated for four weeks at various salinities, and (1) ... | 2001 | 11795174 |
| sperm ultrastructure of shrimp from family penaeidae (crustacea: dendrobranchiata) in a phylogenetic context. | we describe the sperm ultrastructure of six penaeid species, including at least one member of each tribe (penaeini, parapenaeini and trachypenaeini). fragments of the vas deferens of the penaeidae farfantepenaeus brasiliensis, farfantepenaeus paulensis, litopenaeus schmitti, parapenaeus americanus, rimapenaeus constrictus and xiphopenaeus kroyeri were fixed and processed according to the routine for transmission electron microscopy. the morphological results were contextualized in an evolutionar ... | 2017 | 28163192 |
| [characterization of the lipid portion of pink shrimp commercial samples]. | the objective of this study was to describe the fresh cooled pink-shrimp (penaeus brasiliensis and penaeus paulensis) lipid. the total lipid content was 1.13 +/- 0.09 g/100 g while fatty acid profile showed 32.9% saturated, 20.4% monounsaturated and 40.5% polyunsaturated. eighteen fatty acids were detected, seven saturated (14:0, 15:0, 16:0, 17:0, 18:0, 20:0, 22:0), four monounsaturated (16:1w7, 17:1w9, 18:1w9, 20:1w9) and seven polyunsaturated (18:2w6, 18:3w3, 20:2w6, 20:4w6, 20:5w3, 22:5w3, 22 ... | 2002 | 12184157 |
| stock assessment and fishery management of the pink shrimp farfantepenaeus brasiliensis latreille, 1970 and f. paulensis pérez-farfante, 1967 in southeastern brazil (23 degrees to 28 degrees s). | quantitative analyses of the pink shrimp (farfantepenaeus brasiliensis and farfantepenaeus paulensis) fisheries were carried out using data collected from july 1999 to july 2001 from the trawling operations of the fishing fleet based in santos/guarujá, sp. according to classical models, the fishery is at its maximum sustainable yield. therefore, reduction of the fishing effort and adequate season and area closures seem to be the best management actions for the pink shrimp fishery. | 2006 | 16710519 |
| growth and mortalities of the pink-shrimp farfantepenaeus brasiliensis latreille, 1970 and f. paulensis pérez-farfante 1967 in southeast brazil. | from july, 1999 until july, 2001 data from the pink-shrimp farfantepenaeus brasiliensis latreille, 1970 and f. paulensis pérez-farfante, 1967 fishery were collected from trawling by the fishing fleet based in santos/guarujá-sp. growth and mortalities of these species were studied. f. brasiliensis and f. paulensis have longevity of 2 years and growth estimates of l infinity = 29.0 cm and k = 1.24 year-1 for f. brasiliensis and l infinity = 27.5 cm and k = 1.34 year-1 for f. paulensis. females rea ... | 2006 | 16862308 |
