Antigenic characterization ofNephrops norvegicus (L.) hepatopancreas cells

Cell Biochemistry and Function, 1999
During this work structural, differentiation and proliferation antigenic markers developed for mammals were applied in paraffin sections of Nephrops norvegicus (L.) hepatopancreas. The purpose was to establish standards for the characterization of invertebrate cells in vitro. Antibody concentration was optimized for quantification of cell proliferation.

Control of Secretory Production in the Isopod Hepatopancreas

Proceedings, annual meeting, Electron Microscopy Society of America, 1972
The isopod hepatopancreas, as exemplified byOniscus ascellus. is comprised of four blind-ending diverticula. The regenerative cells at the tip of each diverticula differentiate into either club-shaped B-cells, which serve a secretory function, or into conoid S-cells, which serve in the absorption and storage of nutrients.The glandular B-cells begin ...

Copper distribution in Octopus vulgaris lam. Hepatopancreas

Comparative Biochemistry and Physiology, 1969
1. 1. The copper content of Octopus vulgaris Lamarck hepatopancreas was found to be 4880 ± 2549 p.p.m./dry wt. 2. 2. Fifty per cent of the total hepatopancreas copper was extracted after homogenization in 1 M sucrose. 3. 3. Twelve per cent of the soluble copper was separated after 24,500 g centrifugation. 4. 4. The extracted copper was

Carbohydrates of the hepatopancreas and blood tissues of Carcinus

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972
Abstract 1. 1. A detailed comparative analysis of the carbohydrates in the haemolymph and hepatopancreas of Carcinus maenas has been made. 2. 2. Glucose, trehalose, maltose, fructose and fucose were identified in both tissues by thin-layer chromatography (TLC).

Pyrene Biotransformation and Kinetics in the Hepatopancreas of the Isopod Porcellio scaber

Archives of Environmental Contamination and Toxicology, 2004
Various techniques exist for polycyclic aromatic hydrocarbon (PAH) determination in environmental samples, but an adequate risk assessment of PAHs should include aspects such as bioavailability of the contaminant and biotransformation capacity of the species under investigation.

The purine nucleotide cycle inHelix hepatopancreas

Journal of Comparative Physiology ? B, 1979
The enzymes adenylosuccinate synthetase (EC 6.3.4.4 IMP: L-aspartate ligase [GDP-forming]), adenylosuccinate lyase (EC 4.3.2.2) and AMP deaminase (EC 3.5.4.6 AMP aminohydrolase) were demonstrated inHelix aspersa hepatopancreas tissue. The presence of these enzymes along with high levels of aspartate transaminase is presumptive evidence for the ...

Nature of copper in parent prawn hepatopancreas

Chinese Journal of Oceanology and Limnology, 1991
Copper content in the hepatopancreas of wild parentPanaeus orientalis was more than 500 μg/g (wet wt), among which over 90% distributed in the cytosol. 99% of the Cu in the subcellular fraction distributed in a very low molecular weight (VLMW)pool.DE-11 anion exchange chromatography of the VLMW material indicated that about 83% of the Cu in the pool ...

Crayfish hepatopancreas metabolism and the intermoult cycle

Comparative Biochemistry and Physiology, 1962
1. 1. The respiratory rate of crayfish hepatopancreas tissue is shown to be dependent upon the stage in the intermoult cycle. QO2 values are lowest in intermoult and reach a peak in early postmoult. 2. 2. QO2 values are uninfluenced by extracts of eyestalks, cerebral ganglia and thoracic nerve cords when added to respiring tissue in vitro ...

The morphology and physiology of the invertebrate liver and hepatopancreas

Journal of Morphology, 1928
AbstractModifications of the gastro‐intestinal tract of Nereis virens are two dorsolateral esophageal cecums, directed anteriorly and posteriorly from the point of attachment. The cecal and esophageal lumina are continuous. Each cecum is composed of acini, possessing a row of elongated cells, basement membrane, and intima.
