Effect of sexual stages on lipids and fatty acids of Diplodon delodontus

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
Abstract 1. 1. The composition of lipids and fatty acids of male and female gonads of D. delodontus at different sexual stages were studied. 2. 2. The main differences were found in the percentages of triacylglycerols, cholesterol esters and phospholipids. 3. 3.

Spingophosphonolipids in microsomes of Diplodon delodontus. Distribution and effect on the membrane microviscosity

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990
Abstract 1. 1. The distribution of ceramide aminoethylphosphonate (CAEP) in microsomal membranes obtained from different tissues of the bivalve mollusc Diplodon delodontus was determined. 2. 2. The concentration of CAEP reached from 9 to 19% of the total microsomal polar lipids, depending on the kind of tissue. 3. 3. Palmitic acid was the

Role of hemocytes and plasma on lipid transport in the freshwater mollusc Diplodon delodontus

Comparative Biochemistry and Physiology Part A: Physiology, 1985
Abstract 1. 1. Composition of lipids and fatty acids from plasma and hemocytes separated from freshwater bivalve molluscs Diplodon delodontus were studied. In both hemolymph components phospholipids were the major lipids, but quantitative composition of phospholipids and fatty acids was different in hemocytes and plasma indicating specific ...

EFFECT OF AERIAL EXPOSURE ON PHYSIOLOGICAL CONDITION AND SURVIVAL OF DIPLODON CHILENSIS (BIVALVIA: HYRIIDAE) DURING TRANSLOCATION

Malacologia, 2006
Freshwater mussels are an important component of the aquatic biodiversity of Chile, especially in the southern part of the country, and other geographical areas of the northern and southern hemispheres. The most common species in Chile is Diplodon chilensis (Gray, 1828), which is a unique species of Hyriidae with a distribution extending from 34°58’S ...

Transport of cholesterol in the hemolymph of the mollusc Diplodon delodontus

Comparative Biochemistry and Physiology Part A: Physiology, 1987
Abstract 1. 1. The dietary and inter-organ cholesterol transport in the hemolymph of the bivalve mollusc Diplodon delodontus , was studied. Plasma and hemocytes were obtained after feeding labeled cholesterol to animals or injecting it into the posterior adductor muscle. 2. 2. In both cases, cholesterol was incorporated either into plasma or

Biomarkers of oxidative stress and cell damage in freshwater bivalves Diplodon parodizi exposed to landfill leachate

Environmental Science and Pollution Research, 2020
Landfill is a public and environmental health problem; establishing and understanding methodologies to decrease its toxicity are thus necessary. Leachate samples were collected, at a sanitary landfill, immediately after the exit from the landfill, i.e.

Filter feeding by the freshwater mussel, Diplodon chilensis, as a biocontrol of salmon farming eutrophication

Aquaculture, 1999
The freshwater mussel Diplodon chilensis (Hyriidae) is abundant in bays where salmon farming takes place in southern Chilean lakes. In order to evaluate the possibility of mitigating salmon farming impacts through the management of benthic communities, we measured the ability of D.

Gloquídio de Diplodon martensi (lhering) (Mollusca, Bivalvia, Hyriidae) e seu ciclo parasitário [PDF]

Revista Brasileira De Zoologia, 1999
Conchological and anatomical studies of the glochidium of Diplodon martensi (lhering, 1893) were performed on samples collected in a small river, tributary from the Cai River, that belong to the Jacui River sub-basin in south-eastern Brazil. The parasitic development of the glochidium was observed in laboratory on a small cichlid fish Gymnogeophagus ...

Effects of temperature and food availability on the filtration and excretion rates of Diplodon parallelopipedon (Hyriidae)

International Review of Hydrobiology, 2021
AbstractBivalves can consume detritus, bacteria, phytoplankton, and zooplankton by filtering the water column. Ecological attributes like filtration rate (FR) and excretion rate (ER) are particularly important to better understand the role of bivalves in ecosystem.

Oxidative stress in the bivalve Diplodon chilensis under direct and dietary glyphosate-based formulation exposure

Environmental Science and Pollution Research
The aim of this study was to evaluate and compare the effects on biochemical parameters and organosomatic indices in the freshwater bivalve Diplodon chilensis exposed to a glyphosate-based formulation under direct and dietary exposures (4 mg a.p./L).
