Biologically active peptides of king crab hepatopancreas
Applied Biochemistry and Microbiology, 2015Substances of a peptide nature isolated from the hepatopancreas of the king crab Paralithodes camtschaticus exhibited physicochemical properties and membranotropic and specific activities similar to those of membranotropic homeostatic tissue-specific bioregulators previously found in different mammalian and plant tissues.

The Gut, Hepatopancreas and Digestion
1993The isopodan alimentary canal consists of a straight tube and two pairs of digestive glands or hepatopancreas on each side. The subject received attention in early research (see McMurrich 1898; Schonichen 1899; Murlin 1902 for early literature). Later, studies by Schmitz and Schultz (1969), Alikhan (1968, 1969a, 1971) and Hassall and Jennings (1975 ...

Glycosidase activities of the hepatopancreas of the ascidian Pyura stolonifera
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972Abstract 1. 1. Extracts of the hepatopancreas of the tunicate Pyura stolonifera contained a wide range of polysaccharidase activities and also hydrolysed a variety of aryl glycosides. 2. 2. Further kinetic studies indicated that the anomeric glycosides of d -glucoronic acid and of N-acetyl- d glucosamine were hydrolysed by different enzymes.

Antigenic characterization ofNephrops norvegicus (L.) hepatopancreas cells
Cell Biochemistry and Function, 1999During 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, 1972The 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, 19691. 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, 1972Abstract 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, 2004Various 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, 1979The 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, 1991Copper 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 ...
