The present study aims to produce sustained-release algae-based carbohydrate microbeadlets of lipoproteins rich-in carotenoids extracted from organic sea buckthorn fruits. β-carotene represented the major compound of the lipoproteins extracts. Emulsification and algae-based carbohydrates, such as sodium-alginate and kappa-carrageenan, provide an inert environment, allowing the embedded targeted bioactive compounds—lipoproteins rich in carotenoids in our case—to maintain greater biological activity and to have a better shelf life. Furthermore, the microbeadlets prepared from sodium-alginate–kappa-carrageenan (0.75%:0.75% w/v) crosslinked with calcium ions showing 90% encapsulation efficiency have been utilized in HPMC capsules using beadlets-in-a-capsule technology, to use as a delivery system for the finished product. The GI simulated tests performed under laboratory conditions suggested that the sodium-alginate–kappa–carrageenan combination could be useful for the formulation-controlled release of microbeadlets containing lipoproteins rich in carotenoids.

Type Particle

We have reported the maturation of an intracisternal A-type particle in murine plasma cell tumor cultures and three human tumor cell cultures (rhabdomyosarcoma, lung adenocarcinoma, and osteogenic sarcoma) after IUDR-DMSO activation. In all of these studies the A-type particle seems to develop into a form with an electron dense nucleoid, presumably mature, which is also intracisternal. A similar intracisternal A-type particle has been described in leukemic guinea pigs. Although no biological activity has yet been demonstrated for these particles, on morphologic grounds, and by the manner in which they develop within the cell, they may represent members of the same family of viruses.

Close Proximity

Microtubules (MT) are versatile organelles participating in a wide variety of biological activity. MT involvement in the movement and transport of cytoplasmic components has been well documented. In the course of our study on trauma-induced vasogenic edema in the spinal cord we have concluded that endothelial vesicles contribute to the edema process. Using horseradish peroxidase as a vascular tracer, labeled endothelial vesicles were present in all situations expected if a vesicular transport mechanism was in operation. Frequently,labeled vesicles coalesced to form channels that appeared to traverse the endothelium. The presence of MT in close proximity to labeled vesicles sugg ested that MT may play a role in vesicular activity.
