A study of pigments in some developmental stages of &lt;i&gt;Aurelia aurita&lt;/i&gt; Lam
Provedor de dados: 27
Autores: Van den Branden, C.; Van den Sande, P.; Decleir, W.
Unfed polyps of &lt;i&gt;Aurelia aurita&lt;/i&gt; are white. Fed with &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt; nauplii they turn to pinkish because of the canthaxanthin present in the food. The deep brown-red colour of strobila and ephyra is due to melanin.

The cycle of activity in the accessory nidamental glands from cephalopods
Provedor de dados: 27
Autores: Richard, A.; Van den Branden, C.; Decleir, W.
The reproductive system of female cephalopods includes a glandular system (oviduct glands and nidamental glands), which develops considerably during sexual maturation and which plays an important part in the formation of the different egg membranes. It is generally uncoloured. An exception are the nidamental glands in &lt;i&gt;Nautilus pompilius&lt;/i&gt; which are composed of opaque yellowish or yellowish-green tissue (Ref. 1). Moreover all Sepioidea and Myopsida and &lt;i&gt;Ctenopteryx&lt;/i&gt;, a species belonging to the Oegopsida (Ref.2) possess accessory nidamental glands. The most striking property of these glands is their intense coloration varying from yellow to orange and red.  This paper is a comparative study of the accessory nidamental glands...

Functional properties of the hemoglobins of &lt;i&gt;Artemia salina&lt;/i&gt; L.
Provedor de dados: 27
Autores: Van den Branden, C.; D'Hondt, J.; Moens, L.; Decleir, W.
1. In hypoxic conditions &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt; L. forms 3 hemoglobins, which until now had only been characterized by their electrophoretic mobility. 2. We have analysed the oxygen-binding properties of these 3 hemoglobins. 3. HbI shows the lowest oxygen affinity, has an almost negligible Bohr effect and it has no physiological adaptation to temperature changes. 4. HbII shows an intermediate oxygen affinity and a pronounced positive Bohr effect. 5. HbIII has a very high affinity for oxygen, an almost negligible Bohr effect and a good physiological adaptation to temperature changes. 6. By combining the 3 hemoglobins in different proportions &lt;i&gt;&lt;i&gt;Artemia&lt;/i&gt; salina&lt;/i&gt; L. must be able to withstand...

La glande nidamentaire accessoire de &lt;i&gt;Sepia officinalis&lt;/i&gt; L.: analyses biochimiques des pigments des bactéries symbiotiques
Provedor de dados: 27
Autores: Van den Branden, C.; Richard, A.; Lemaire, J.; Decleir, W.
An electron microscopic study of the accessory nidamental glands from &lt;i&gt;Sepia officinalis&lt;/i&gt; 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.

Carotenoid producing bacteria in the accessory nidamental glands of &lt;i&gt;Sepia officinalis&lt;/i&gt; L.
Provedor de dados: 27
Autores: Van den Branden, C.; Gillis, M.; Richard, A.
1. The accessory nidamental glands of the cuttlefish, &lt;i&gt;Sepia officinalis&lt;/i&gt; 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.
