Pavement cell ultrastructural differences on Hoplias malabaricus, gill epithelia

Journal of Fish Biology, 1996
Pavement cells from the leading and trailing edges of the gill filament of Hoplias malabaricus, exhibit a complex system of microridges, a long tight junction and a large number of desmosomes. Pavement cells from the secondary lamellae are smooth surfaced with clearly defined cell boundaries by a circular microridge.

Responses of the teleost Hoplias malabaricus to hypoxia

Environmental Biology of Fishes, 1984
Oxygen uptake (VO2) during graded hypoxia, rate of hypoxia acclimation, breathing frequency (fR), breath volume (VS, R) and gill ventilation (VG) were measured in Hoplias malabaricus. Normoxia and hypoxia acclimated fish had similar and constant VO2 and VG in a range of water PO2 from 150 to 25 mmHg.

The multiple soluble malate dehydrogenase of Hoplias malabaricus(Erythrinidae, Characiformes)

Experimental Biology Online, 1997
To explain the six-banded pattern obtained upon electrophoresis of the soluble form of malate dehydrogenase (sMDH, EC 1.1.1.37) from the characiform Hoplias malabaricus, a recent locus duplication of its A isoform (sMDH-A*), in addition to its sMDH-B* isoform, was proposed.

New Insights into the Biogeographic and Karyotypic Evolution of Hoplias Malabaricus

Zebrafish, 2014
Hoplias malabaricus is a species widely distributed throughout Brazil. Cytogenetic studies indicate the occurrence of extensive chromosomal rearrangements in population differentiation and speciation of the group that demonstrated an independent origin of sex chromosome systems.

Toxic effects of DDT and methyl mercury on the hepatocytes from Hoplias malabaricus

Toxicology in Vitro, 2008
Here, we examined the impact of dichlorodiphenyltrichloroethane (DDT) and monomethyl mercury (MeHg) on the redox milieu and survival of hepatocytes from Hoplias malabaricus (traíra). After isolation and attachment of cells, we established one control and four treatments: DDT (50nM of DDT), MeHg I (0.25microM of MeHg), MeHg II (2.5microM of MeHg) and ...

Genotoxic evaluation of different doses of inorganic lead (PbII) in Hoplias malabaricus

Environmental Monitoring and Assessment, 2008
Different genetic biomarkers have been used to evaluate the pollution effects of mutagenic agents such as metals and also a great variety of chemicals delivered on the environment by human activities. This way, the aim of the present report was to evaluate the effects of inorganic lead in fishes through the frequency of piscine micronuclei and nuclear ...

The X1X2Y sex chromosome system in the fish Hoplias malabaricus. II. Meiotic analyses

Chromosome Research, 1998
The neotropical fish Hoplias malabaricus shows diversified cytotypes and may represent a group of distinct species. One of these cytotypes is characterized by 2n = 40 and 2n = 39 chromosomes in females and males, respectively, with a multiple sex chromosome system of the X1X1X2X2/X1X2Y type.
