The photoelec t rochemical behavior of n and p I n P single crys taI semiconductors was inves t iga ted in acetoni t r i le (ACN) solutions which contained var ious e lect roact ive compounds. The cyclic vo l t ammograms of the semiconductors in the d a r k and i l lumina ted wi th red l ight were compared to the Nerns t ian behavior at a P t d isk electrode. The ex ten t of photodissolut ion o...

Controlled Release Systems in the world. In comparison with other Controlled Release Devices, they have the advantage of their low cost and simple technology, that facilitates their application to an important sector of the population, as well as their safety against the dose dumping (accidental fast release of the whole drug dose). Another advantage of these matrices concerns the drug release ...

The mucosal membrane of the oral cavity displays at times classical developmental lesions considered to be variations of normal structures rather than having disease characteristics. Of these lesions leukoedema, Fordyce granules, geographic-, fissured- and hairy tongue, median rhomboid glossitis and lingual varices were studied in 598 patients referred to the School of Dentistry, Tehran, Iran. ...

active saponin constituents from Camellia (C.) sinensis (Theaceae), we have reported the isolation and structure elucidation of theasaponins A1—A5, C1, E1—E13, F1—F3, G1, G2, and H1, 2—6) assamsaponins A—I, and camelliasaponins B1 and C1 9) from the seeds of Japanese C. sinensis (L.) O. KUNTZE and Sri Lankan C. sinensis L. var. assamica PERRE, and foliatheasaponins I—V from the leaves of Japane...

Temporal Text Mining (TTM) is concerned with discovering temporal patterns in text information collected over time. Since most text information bears some time stamps, TTM has many applications in multiple domains, such as summarizing events in news articles and revealing research trends in scientific literature. In this paper, we study a particular TTM task – discovering and summarizing the ev...

introduction: we have recently reported the presence of two potassium currents with 598 and 368 ps conductance in the rough endoplasmic reticulum (rer) membrane. the 598 ps channel was voltage dependent and atp sensitive. however, the 368 ps channel was rarely observed and its identity remained obscure. since cationic channels in intracellular organelles such as mitochondria and rer play import...
