background: recent evidences have supported migraine headache and neurally mediated syncope as the especial types of endotheliopathies. to determine endothelial function in patients with migraine headache or those with neurally mediated syncope,the present study was conducted. materials and methods: this cross-sectional study was performed on 93 consecutive patients aged 5-20 years in four grou...

This chapter explores how, in a single decade (1995-2005), research into computer-mediated communication (CMC) has evolved by examining the Journal of Computer-Mediated Communication (JCMC). JCMC is a peer-reviewed, interdisciplinary, open-access electronic journal that publishes primarily empirical research and presents a significant body of work falling under the rubric of CMC. JCMC has publi...

This collection of articles was originally inspired by several presentations at CATaC’04 and subsequent critical discussion of their use of the frameworks for cultural analyses developed by Edward T. Hall (1966, 1976) and Gert Hofstede (e.g., 1980, 1991). In response to these presentations and discussion, we developed this special thematic section for the Journal of Computer-Mediated Communicat...

a cloud point extraction process using the nonionic surfactant triton x-114 to extracturanium from aqueous solutions was investigated. the method is based on the complexationreaction of uranium with arsenazo iii and micelle-mediated extraction of the complex. theoptimal extraction and reaction conditions (e.g., ph, reagent concentration, effect of time) werestudied, and the analytical character...

Treating Central Nervous System (CNS) neuro-inflammational disorders is of great importance. A key aspect of this treatment includes regulation of Cell-Mediated and humoral immune systems. Previous treatment mostly consisted of systemic immunosuppressive drugs. In addition to having adverse side effects, these drugs were also inefficient, such as methotrexate- Cyclophosphamide-Azathioprine. Rec...

The high crystallinity ZnO nanoparticles with an average particle diameter 30 nm have been successfully synthesized with a surfactant-mediated method. The cationic surfactant (cetyltrimethylammonium bromide, CTAB) and the hydrous metal chlorides (ZnCl2⋅2H2O) appear to be the good candidates for obtaining a high yield of nanoparticles. The structural and morphological characterizations were carr...
