Composition and metabolism of phospholipids in Octopus vulgaris and Sepia officinalis hatchlings

Steroidogenesis in the brain of Sepia officinalis and Octopus vulgaris.

The presence of vertebrate-like steroids, steroidogenic enzymes and steroid receptors has been reported exclusively in cephalopods gonads. The role played by these steroids has been also recently investigated. We here give evidence of steroidogenic activity in the brain of cephalopods. The activity of two key steroidogenic enzymes: 3beta-hydroxysteroid dehydrogenase (HSD) and 17beta-HSD is pres...

Composition in essential and non-essential elements of early stages of cephalopods and dietary effects on the elemental profiles of Octopus vulgaris paralarvae

During the present study, we aimed at providing a first look at the elemental composition of the early stages of cephalopods as an approach to their elemental requirements in culture. Essential and non-essential elemental profiles of the European cuttlefish Sepia officinalis, the European squid Loligo vulgaris and the common octopus Octopus vulgaris laboratory hatchlings and wild juveniles were...

In Vivo Metabolism of Unsaturated Fatty Acids in Sepia Officinalis

Ecology of Sepia Officinalis

This article comprises an up-dated review of the processes influencing the distribution and abundance of common cuttlefish Sepia officinalis, the interactions between the species and the main parameters of the environment in which it lives and its trophic, demographic and behavioural ecology.

synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
