Inducible Nitric Oxide Synthase mRNA Expression and Nitric Oxide Production in Silica-Induced Acute Inflammatory Lung Injury
JiheeLee 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 7 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1998, Vol.2 No.2 12 233-239 (7 pages)
Stimulated alveolar macrophages and neutrophils produce nitric oxide, a free radical by an inducible nitric oxide synthase(iNOS), which reacts with superoxide anion to form peroxynitrite, a more highly reactive toxic species. The objectives of the present study were to evaluate acute inflammatory lung injury and to determine iNOS mRNA induction and nitric oxide production by rat broncho-alveolar lavage cells following intratracheal treatment of silica. After 4 h exposure to silica, differential... -
Phylogenetic Analysis of Phaeosphaeria Species Using Mating Type Genes and Distribution of Mating Types in Iran

Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates including 67 isolates obtained from symptomatic leaves and ears of wheat, barley, and wild grasses from two wheatgrowing region in Iran as well as 206 isolates from our collection from other regions in Iran which were isolated in our previous... -
Effect of the surface modification using MWCNTs with different L/D by two different methods of deposition on the IFSS of single carbon fiber-epoxy resin composite

were surface treated using nitric acid (HNO3) and polyethyleneimine (PEI) prior to their deposition on carbon fibers (CF). Before the hierarchical reinforcement with CF-MWCNT, the CFs were treated with 3-glycidoxypropyltrimethoxysilane, a coupling agent (Z6040) and with poly(amidoamine) (PAMAM) a dendrimer containing an ethylenediamine core and amine surface groups. The MWCNT were deposited on the CF using two methods, by electrostatic attraction and by chemical reactions. The changes in the CF... -
Mechanical and electrical properties of epoxy resin/epoxidized castor oil/carbon fiber cloth composites
Fan-Long Jin, Heng Zhang, Shan-Shan Yao, Soo-Jin Park 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 12 105-109 (5 pages)
Carbon fibers (CFs) have a unique combination of outstanding mechanical, physical, and chemical properties and are among the materials most frequently used in the preparation of a large variety of composites [1-5]. CF-reinforced polymer composites have been widely used in many advanced technological fields, such as aerospace, engineering, sporting goods, automobiles, and marine industry during the past few decades due to their excellent properties, including high strength-to-weight ratios, light... -
Effect of fiber-matrix adhesion on the fracture behavior of a carbon fiber reinforced thermoplastic-modified epoxy matrix

한국탄소학회 Carbon Letters 2016, Vol.19 6 47-56 (10 pages)
In this study, the fracture behavior of a thermoplastic-modified epoxy resin reinforced with continuous carbon fibers for two levels of fiber-matrix adhesion was performed. A carbon fiber with commercial sizing was used and also treated with a known silane, (3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved...
