Drosophila Serpin-28D regulates hemolymph phenoloxidase activity and adult pigmentation.
In insects the enzyme phenoloxidase (PO) catalyzes melanin deposition at the wound site and around parasitoid eggs. Its proenzyme prophenoloxidase (proPO) is proteolytically cleaved to active phenoloxidase by a cascade consisting of serine proteases and inhibited by serpins. The Drosophila genome encodes 29 serpins, of which only two, Serpin-27A (Spn27A) and Necrotic, have been analyzed in deta...
متن کاملSpectral sensitivity of four species of fiddler crabs (Uca pugnax, Uca pugilator, Uca vomeris and Uca tangeri) measured by in situ microspectrophotometry.
Fiddler crabs have compound eyes that are structurally fairly well understood. However, there has been much debate regarding their spectral sensitivity and capacity to enable colour discrimination. We examined the visual pigments of two North-American species (Uca pugnax and U. pugilator), one species from the Indo-West Pacific (U. vomeris) and the only Eastern-Atlantic species (U. tangeri) of ...
متن کاملTetrahydrobiopterin corrects Escherichia coli endotoxin-induced endothelial dysfunction.
Acute inflammation causes endothelial dysfunction, which is partly mediated by oxidant stress and inactivation of nitric oxide. The contribution of depletion of tetrahydrobiopterin (BH(4)), the cofactor required for nitric oxide generation, is unclear. In this randomized, double-blind, three-way crossover study, forearm blood flow (FBF) responses to ACh and glyceryltrinitrate (GTN) were measure...
متن کاملAlterations in the Blood Coagulation System Induced by Bacterial Endotoxin
The intravenous injection of bacterial endotoxins alter the coagulation system of rabbits' blood in vivo. Twenty-four hours after the first injection the fibrinogen level rises to twice normal values. The second injection at this time causes a 30 to 40 per cent decrease in fibrinogen content in 4 hours. Twenty hours later it again rises to twice normal values. A marked decrease in whole blood c...
متن کاملMUDBALLINGREVISITED: FURTHER INVESTIGATIONS INTO THE CONSTRUCTIONBEHAVIOUROF MALE UCA TANGERI by FIONA
Male and female Uca tangeri (the only ddler crab species to inhabit Europe) construct mudballs from mud excavated from within their burrows. Individual males placed similar patterns of mudballs each low tide, suggesting that there is some degree of stereotypy. When mudballs were experimentally moved further from the burrow or closer to it, males only repositioned those that were moved closer,...
