CHH, on osmoregulatory parameters in a freshwater crustacean. The effects of eyestalk ablation and CHH
exposed to a wide range of salinities. According to the salinity of the medium, they are submitted to osmotic water exchanges and diffusive ion movements between their hemolymph and the external medium. In order to maintain their hydromineral balance, euryhaline crustaceans are able to regulate their body fluid through a decrease in the tegument permeability and an active uptake or excretion of...
متن کاملCrustacean hyperglycemic hormone is synthesized in the eyestalk and brain of the crayfish Procambarus clarkii
Crustacean hyperglycemic hormone (CHH) is a neuropeptide that is synthesized, stored, and released by brain and eyestalk structures in decapods. CHH participates in the regulation of several mechanisms, including increasing the level of glucose in hemolymph. Although CHH mRNA levels have been quantified and the CHH protein has been localized in various structures of the crayfish P. clarkii, CHH...
متن کاملDevelopment of Palladium-Alloy Membranes for Hydrogen Separation and Purification
This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...

determination of thespanwise variation of moment distribution and indicates that the effect of finite span modifies the zero lift properties which the two-dimensional theory predicts. It is thought that the idea underlying the proposed two-equation procedure, which may be extended to an n-equation procedure, will also be useful in other problems of lifting-surface theory. Summary.-The steady mo...
متن کاملThe specific binding sites of eyestalk- and pericardial organ-crustacean hyperglycaemic hormones (CHHs) in multiple tissues of the blue crab, Callinectes sapidus.
Crustacean hyperglycaemic hormone from the pericardial organ (PO-CHH) is a CHH-related neuropeptide but its function and target tissues are not known in crustaceans. To investigate this issue, we employed radiolabelled ligand binding and cGMP assays, using eyestalk-CHH (ES-CHH) as a reference neuropeptide. The membranes were prepared from various tissues of Callinectes sapidus: hepatopancreas, ...
