Última Carotenoid producing bacteria in the accessory nidamental glands of <i>Sepia officinalis</i> L. OMA Van den Branden, C.; Gillis, M.; Richard, A.. 1. The accessory nidamental glands of the cuttlefish, <i>Sepia officinalis</i> L. show an intensive orange-red coloration in mature females. This colour is due to carotenoid pigments which occur in symbiotic bacteria. 2. Six different pigmented strains of bacteria were isolated. 3. The main pigment in five of these strains is beta-carotene. 4. The main pigment in the sixth strain is the keto carotenoid, adonixanthin.

Ano: 1980 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=3643 La glande nidamentaire accessoire de <i>Sepia officinalis</i> L.: analyses biochimiques des pigments des bactéries symbiotiques OMA Van den Branden, C.; Richard, A.; Lemaire, J.; Decleir, W.. An electron microscopic study of the accessory nidamental glands from <i>Sepia officinalis</i> L. shows a secretory cycle in the epithelial cells and the presence of bacteria in the tubules of the gland. A correlation between sexual maturity, the color of the gland and the total number of symbiotic bacteria can be demonstrated. A biochemical study shows that the correlation of the gland is due to several carotenoid pigments. The most important of these is an orange-red xanthophyll that has been called Sepiaxanthine. It is probably formed in the bacteria as a result of the secretory activity of the epithelial glandular cells. This whole mechanism and the role of the bacteria and pigments need further research.

Ano: 1979 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=3618 A study of the orange-red pigment from the accessory nidamental glands of the cephalopod <i>Sepia officinalis</i> L. OMA Decleir, W.; Richard, A.. In adult female cuttlefish an orange-red pigment concentrates in the accessory nidamental glands. This pigment is tightly bound to granules which are actively secreted by the glands. The only way to dissolve the pigment is an incubation in 40 % NaOH. Afterwards the pigment becomes readily soluble in most organic solvents. Its solubility, its behaviour in thin layer chromatography and its visible adsorption spectrum prove that the pigment is a carotenoid. It is probably formed by oxidation of a carotene. Since its properties do not correspond entirely with those of the known carotenoids, the new cephalopod pigment was called Sepiaxanthine.

Ano: 1972 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=3453 Determination of protein-bound copper and zinc in some organs of the cuttlefish <i>Sepia officinalis</i> L OMA Decleir, W.; Vlaeminck, A.; Geladi, P.; Van Grieken, R.. 1. The copper, zinc and iron content of blood and water soluble extracts from several organs of <i>Sepia officinalis</i> L. have been determined with atomic absorption spectrometry. 2. The relatively high concentration of copper and zinc in the branchial gland points to its probable role in trace element metabolism. 3. After gel filtration a low molecular weight copper and zinc containing fraction can be isolated from the gland. 4. A possible role of this fraction in hemocyanin biosynthesis is postulated.

(Mollusque Céphalopode) OMA Decleir, W.; Richard, A.; Lemaire, J.; Wolf, G.. The branchial gland from the cuttlefish (cephalopod mollusc) consists of extensively irrigated tissue, which shows a typical ultrastructure of protein-secreting cells: prominent nucleolus, elaborate system of granular endoplasmic reticulum and active Golgi apparatus. The possible hemopoietic role of the gland is sustained by our biochemical results. Tipo: Info:eu-repo/semantics/article Palavras-chave: Sepia officinalis Linnaeus; 1758 [Common cuttlefish].

Organogenèse OMA Lemaire, J.; Richard, A.; Decleir, W.. The rudiments of the "hepatopancreas" appear early, in stage 20, as a pair of diverticula, given off from the midgut. The anterior part which lies against the yolk-sac will become the "liver". The growth of the liver exhibits a close relationship to the development of the inner yolk-sac. An electron microscopic study has been made of the hepatic epithelium at different embryonic stages. From stage 27, the cytologic aspects of the hepatic cell (presence of "balls", cytoplasm with well developed granular endoplasmic reticulum and free ribosoms...) give evidence of secretory activity. These ultrastructural features show that the liver becomes functional and allow us to think that it plays a part in the embryonic metabolism during the last stages of...
