Generation of reactive oxygen species by leukocytes of Prochilodus lineatus

Fish Physiology and Biochemistry, 2013
Prochilodus lineatus (curimbatá), from the Procholodontidae family, is a Brazilian freshwater fish, which is important commercially, nutritionally and ecologically. It is encountered in the Rio da Prata Bay in Southern South America. Studies on the immune system of this fish are scarce, but the physiological mechanisms of the species are analogous to ...

Acute effects of diflubenzuron on the freshwater fish Prochilodus lineatus

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2008
The effects of diflubenzuron (DFB), an insecticide to control ectoparasites in fish farms, on muscle acetylcholinesterase (AChE), detoxifying and antioxidant enzymes, hematological and physiological parameters, and liver histopathology were evaluated in Prochilodus lineatus after 6, 24 and 96 h of exposure to 25 mg L(-1) of DFB.

Description and comparison of two economically important fish species mitogenomes: Prochilodus argenteus and Prochilodus costatus (Characiformes, Prochilodontidae)

Mitochondrial DNA Part A, 2015
Prochilodus spp. are important Brazilian freshwater migratory fishes with substantial economic and ecological importance. Prochilodus argenteus and Prochilodus costatus are morphologically similar and a molecular species delimitation is impaired due to high degree of sequence identity among the available genetic markers.

Cytogenetic Markers in Wild Population of Curimbata (Prochilodus lineatus) From Mogi-Guacu River

Cytologia, 2009
Within the genus Prochilodus, the species Prochilodus lineatus is certainly the most studied one from a cytogenetic point of view. In this study, a cytogenetic characterization of specimens of P. lineatus from Mogi-Guacu River was performed in the period

Interaction of non-ionic surfactants with hepatic CYP in Prochilodus scrofa

Toxicology in Vitro, 2004
Cytochromes P450 (CYP) constitute a superfamily of hemeproteins that play a vital role in the metabolism of a wide variety of endogenous and xenobiotic compounds. Xenobiotic metabolism and the role of CYP are of particular interest in studies regarding the prevention of the damage caused by chemical pollutants.

Induced breeding of the sabalo, Prochilodus platensis Holmberg

Aquaculture, 1984
Abstract Maturation and ovulation were induced in female Prochilodus platensis with multiple homologous pituitary extract injections (total dose 0.9 to 1.4 hypophysis/kg) or single injections of pituitary extract combined with human chorionic gonadotrophin ((1 hypophysis + 500 I.U.)/kg). One of the females given the latter treatment produced viable

Biomarkers of waterborne copper exposure in the Neotropical fish Prochilodus lineatus

Aquatic Toxicology, 2016
The main goal of the present study was to investigate the effects of acute exposure to copper (Cu) using a Neotropical freshwater fish as sentinel species through multi biomarkers analysis at different biological levels. Juveniles of Prochilodus lineatus were kept under control condition (no Cu addition in the water) or exposed to environmentally ...

B-chromosome frequency stability in Prochilodus lineatus (Characiformes, Prochilodontidae)

Genetica, 2009
The genus Prochilodus includes individuals ranging in size from medium to large, being highly relevant for commercial and subsistence fishing. Prochilodus species have a diploid number of 2n = 54 chromosomes and up to seven supernumerary (B) microchromosomes.

Histology, histochemistry and stereology of the adipose fin of Prochilodus lineatus

Microscopy Research and Technique, 2011
AbstractThe adipose fin is small, nonpared, and usually located medially between the dorsal and caudal fin. Its taxonomic occurrence is very restrict; thus, it represents an important trace for taxon distinction. As it does not play a known vital physiological roll and it is easily removed, it is commonly used in marking and recapture studies.

Lead accumulation and its effects on the branchial physiology of Prochilodus lineatus

Fish Physiology and Biochemistry, 2013
The purpose of this work was to determine the tissue accumulation of lead (Pb) and its effects on osmoregulatory processes of the freshwater fish Prochilodus lineatus. Juvenile fish were exposed to Pb (from 1.7 to 0.7 mg of dissolved Pb L(-1)) for 6, 24 and 96 h and Pb accumulation was analyzed in the gills, liver, kidneys, blood cells and muscle.
