Carotenoids in Marine Animals
Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals p...

and insulin in birds. Insulin potentiates the glucagon stimulation of lipolysis (Langslow & Hales, 1969), whereas in rat adipose tissue insulin has an antilipolytic effect on glucagon-stimulated lipolysis. In the rat, insulin stimulates lipogenesis in the adipose tissue, whereas avian adipose tissue is either poorly sensitive or insensitive to the lipogenic action of insulin (Kompiang & Gibson,...
متن کاملCutaneous injuries from marine animals.
Cutaneous injuries by marine animals have a myriad of clinical presentations. Most require only symptomatic treatment, but some may be limb-threatening or even fatal. This is a report of three cases of marine animal injuries by a stingray, a sea anemone and a jellyfish, respectively, illustrating the potential severity of such injuries. The importance of early diagnosis is emphasised, with a di...
متن کاملEvolution of plant parasitism among nematodes.
Despite extraordinary diversity of free-living species, a comparatively small fraction of nematodes are parasites of plants. These parasites represent at least three disparate clades in the nematode tree of life, as inferred from rRNA sequences. Plant parasites share functional similarities regarding feeding, but many similarities in feeding structures result from convergent evolution and have ...
