Modulation of gastric mucosal inflammatory responses to Helicobacter pylori by ghrelin: Role of cNOS-dependent IKK-β S-nitrosylation in the regulation of COX-2 activation
(Scientific Research Publishing, 2012-04)Disturbances in nitric oxide synthase (NOS) and cyclooxygenase (COX) isozyme systems, manifested by the excessive NO and prostaglandin (PGE2) generation, are well-recognized features of gastric mucosal inflammatory responses ... -
Design of Low Power and High Speed CMOS Comparator for A/D Converter Application
(Scientific Research Publishing, 2012-04)This paper presents an improved method for design of CMOS comparator based on a preamplifier-latch circuit driven by a clock. Design is intended to be implemented in Sigma-delta Analog-to-Digital Converter (ADC). The main ... -
The effects of astragalus polysaccharide on zebrafish cell apoptosis and senescence
(Scientific Research Publishing, 2012-04)Astragalus polysaccharide (AP) is the extraction of astragalus, which is a plant used in traditional Chinese herb medicine and may increase an orgainism’s resistance to stress. Several earlier studies in vitro have indicated ... -
P2P Model Based on Isolated Broadcast Domains
(Scientific Research Publishing, 2012-04)Resource location is the most important issue for Peer-to-Peer (P2P) system and flooding is the fundamental mechanism for unstructured P2P systems. Redundant messages will exponential growth with flooding scope increasing ... -
Software Defined Radio Prototyping with Visual C++ Express and Code Composer Studio
(Scientific Research Publishing, 2012-04)The primary goal of this project was educational: to demonstrate Software Defined Radio based prototyping using Visual C++ Express and Code Composer Studio. More specifically an IEEE802.11a Phy [1] compliant baseband ... -
Solving the independent set problem by sticker based DNA computers
(Scientific Research Publishing, 2012-04)In this paper, the sticker based DNA computing was used for solving the independent set problem. At first, solution space was constructed by using appropriate DNA memory complexes. We defined a new operation called “divide” ... -
A multi-criteria decision-making approach for comparing sample preservation and DNA extraction methods from swine feces
(Scientific Research Publishing, 2012-04)Molecular microbiological methods, such as competetive PCR, real-time PCR, denaturing gradient gel electrophoresis (DGGE) and large-scale parallel-pyrosequencing, require the extraction of sufficient quantity of high quality ... -
Molecular cloning and characterization of fruit specific promoter from Cucumis sativus L.
(Scientific Research Publishing, 2012-04)The isolation and characterization of fruit specific promoters are critical for the manipulation of nutritional value and agronomic quality of fruits by genetic engineering and also opened a new era in edible vaccine ... -
Expression of the transcription factor Xvent-2 in Xenopus laevis embryogenesis
(Scientific Research Publishing, 2012-04)Till now the transcription factor Xvent-2 has been studied in Xenopus embryos only by the mRNA testing. We use immunochemical methods for testing of the Xvent-2 protein and gradient-centrifugation methods for estimation ... -
Tandem repetitions in transcriptomes of some Solanaceae species
(Scientific Research Publishing, 2012-04)Characterization of occurrence, density and motif sequence of tandem repeats in the transcribed regions is helpful in understanding the functional significance of these repeats in the modern genomes. We analyzed tandem ... -
The Effects of Communication Efficacy on Information-Seeking Following Events That Increase Uncertainty: A Cross-Lagged Panel Analysis
(Published Online, 2012-05)This study examined how past information-seeking experience influences individuals’ information-seeking decision process following an event that increases uncertainty in close relationships. To examine this issue, a two-wave, ... -
A Novel Technique for Determination of Flow Characteristics of Blast Furnace Slag
(Scientific Research, 2012-06)A study of flow characteristics of blast furnace slag helps determine its softening and flow (liquid-mobility) temperatures. The slag with a narrow difference between the two temperatures is termed a “Short Slag”. Its ... -
Cardiac Immobilization in Beating Heart Surgery Using Pericardial Bands
(Scientific Research, 2012-06)A novel technique of stabilization of the coronary targets with autogenous pericardial bands is described in off pump coronary revascularizations. Pericardial bands are placed across the coronary targets and snared to the ... -
Mazumder Effect of Liquid and Gas Velocities on Magnitude and Location of Maximum Erosion in U-Bend
(Scientific Research, 2012-06)Solid particle erosion is a micromechanical process that is influenced by flow geometry, material of the impacting surface, impact angle, particle size and shape, particle velocity, flow condition and fluid properties. ... -
Modeling Evaporating Droplets in Complex Unsteady Flows
(Scientific Research, 2012-06)In many applications, a moving fluid carries a suspension of droplets of a second phase which may change in size due to evaporation or condensation. Examples include liquid fuel drops in engines and raindrops or ice-crystals ... -
Detecting Ultra-Violet Radiation by Using Titanium Dioxide Nanoparticles
