The choline required for synthesis of acetylcholine is derived exogenously by Aplysia ganglia. Under physiological conditions choline was taken up primarlily by neuropile and nerves and not by cholinergic cell bodies. In addition, compared with their contents of choline acetyltransferase, those components of nervous tissue which contain nerve terminals and axons synthesized acetylcholine far m...

Minimax location problems have rece ived considerable attention in the literature as models for locating fac ilities tha t are to provide emerge ncy or convenient service to a set of ex isting facilities. In most of these problems the re is given a set of ex isting facilities whose locations are represented as points in some space, and new fac ility locations are also to be spec ified as points...

introduction dragonhead (dracocephalum moldavica l.) is an annual herbaceous aromatic plant and belongs to lamiaceae family. it is native to south of siberia and himalayan hillsides. the essential oil content shows great variation due to plant origin. the main constituents of dragonhead essential oil have been reported as geranial, geranyl acetate, neral and geraniol. using organic manures and ...

For the purpose to investigate the physiological functions of microvillus ATPase, general properties of the enzyme were studied on the microvillus membranes isolated from rabbit intestinal epithelial cells. 1) ATPase of the microvillus membranes was activated with Mg2+. Mg.ATP complex was thought to be a subStrate of the enzyme. The Michaelis constant for ATP of the ATPase was a value of 0.8 to...

Bacteriorhodopsin and rhodopsin are integral membrane proteins containing retinal as a light sensitive group. Light energy is used by halophilic microorganisms for ATP synthesis and other vital functions. In visual cells light absorption activates several enzymes in the rod outer segment. Comparative study of the structural organization of these proteins was necessary to elucidate their functio...

Hydrodistilled leaves and fruits of Hoslundia opposita yielded 0.54% and 0.65%v/w of essentials oils. Investigation by GC and GC-MS revealed that the bulk of the oils were constituted by oxygenated monoterpenes (81.3 and 81.4% for the leaves and fruits, respectively). The principal constituents of the leaf oil were 1, 8-cineole (72.3%), terpineol (7.2%), sabinene (4.5%), thymol (4.2%) and car-3...
