Non-invasive methods have been proposed as surrogate markers for liver biopsy. It was shown that serum hyaluronic acid (HA) and laminin (LN) levels increase with the development of liver fibrosis. The aim of this study was to determine serum HA and LN levels cut-off points for predicting liver fibrosis, highlighting their diagnostic value and their changes during treatment.Serum HA and LN levels in chronic hepatitis patients (n=62) and controls (n=20) were assessed by ELISA and liver histopathological ...

Formation of supercavity around an underwater vehicle improves the hydrodynamic performance of fluid flow and causes vehicle to reach higher speeds. However, sound generated by the supercavitation is very effective in recognition of the vehicle and reduction in its controlled precision. In this study, compressible Navier–Stocks equations were solved by using the method of Large Eddy Simulation and combining them with the physical source and sink model to simulate supercavitation flow numerically. ...

Irregular patterns of precipitations from temporal as well as spatial perspectives not only cause destructions but also waste surface water resources. Hence, controlling surface water and leading the flood to underground stores improve the efficiency of water usage. Selecting appropriate sites for optimal use of water floods is one of the most important factors in recharging underground water tables in dry lands where the agricultural and rangelands are vulnerable. Traditional methods of site selections ...

To compare fatalities and injuries in road traffic crashes (RTC) in Iran with other countries. Data were obtained from national health sources of Iran. These data included population number, registered motor-vehicles number, number of RTCs and consequent fatalities and injuries from 1997 to 2006. RTC fatality and injury rates increased from 1997 to 2005, but decreased in 2006. The over all men/women ratio in the RTC fatalities was 4.2:1. High RTC fatality rate of 39 per 100 000 population in Iran ...

The uniaxial compressive strength (UCS) of limestone rocks was estimated by indentation testing on small rock fragments. The effects of rock fragment dimensions (particularly area and thickness) on indentation indices were studied. The investigation shows a size dependency of the conventional indentation parameters. The results indicate the fragment area normal to loading direction has little effect on the indentation indices, while the sample thickness has major influence on the results. To reduce ...

This paper presents the results of an investigation into the post-buckling behaviour and ultimate strength of imperfect pitted steel plates used in ship and other marine-related structures. A series of elastic-plastic large deflection finite element analyses is performed on pitted steel plates. The effects of pitting corrosion on one side of the plates are introduced into the finite element models. The effects on plate compressive strength as a result of parametric variation of the pitting corrosion ...

Abstract Natural silk, from Bombyx mori solutions were electrospun into nanofibers, with diameters ranged from 60 to 7000 nm. The effects of electrospinning temperature, solution concentration and electric field on the formation nanofibers were studied. Optical and scanning electron microscope were used to study the morphology and diameter of electrospun nanofibers. It was observed that the nanofibers became flattened with ribbon‐like shape with increasing the electrospinning temperature. The nanofiber ...

The electrodeposition of cobalt, nickel and Ni–Co alloys was studied by electrochemical techniques. Cyclic voltammetry and current transient measurements were used to characterize the Co–Ni system in other to obtain the nucleation and growth mechanism. The cyclic voltammetry results clearly showed that electrodeposition of cobalt, nickel and Co–Ni alloy is diffusion-controlled process with a typical nucleation mechanism. The redox potentials of the Co and Ni are shifted to more cathodic potentials ...

Active targeting could increase the efficacy of anticancer drugs. Methotrexate-human serum albumin (MTX-HSA) conjugates, functionalized by luteinizing hormone-releasing hormone (LHRH) as targeting moieties, with the aim of specifically targeting the cancer cells, were prepared. Owing to the high expression of LHRH receptors in many cancer cells as compared to normal cells, LHRH was used as the targeting ligand in this study. LHRH was conjugated to MTX-HSA nanoparticles via a cross-linker. Three types ...

A critical issue in contemporary orthodontics is bone age estimation. The most reliable method for skeletal age evaluation is hand–wrist radiography; but it requires further radiation. There is an increasing attention for evaluating cervical vertebrae to reduce the radiation to the patients. The aim of this study was to estimate bone age by measuring 3rd and 4th cervical vertebrae (C3, C4) dimensions. We conducted a correlational study on 91 Iranian individuals aged 8-18 years. After taking lateral ...

During the period from December 2008 to September 2009, we examined 254 serum samples (164 in hot-dry weather and 90 in cold-dry weather) from dromedary camels distributed all over Yazd Province, in the center of Iran. IgG antibodies were assayed by the modified agglutination test (MAT) and Neospora agglutination test (NAT) using whole tachyzoites of Toxoplasma gondii and Neospora caninum, incorporating 2-mercaptoethanol, for T. gondii and N. caninum, respectively. Anti-T. gondii antibodies were found ...

Abstract The Tarom 1: 100,000 sheet is located within the Cenozoic Tarom-Hashtjin volcano-plutonic belt, NW Iran. Reconstruction of the tectonic and structural setting of the hydrothermal deposits is fundamental to predictive models of different ore deposits. Since fractal/multifractal modelling is an effective instrument for separation of geological and mineralized zones from background, therefore Concentration-Distance to Major Fault (C-DMF) fractal model and distribution of Cu anomalies were used ...

The roles of positive and negative affect in well-being were studied in two different societies, namely the Iranian and the Swedish. A total of 606 university students (296 Iranian and 310 Swedish) participated in the study. The results showed that, whereas there was no difference between Iranian and Swedish participants in their general level of life satisfaction, differences with regard to positive and negative affect were found. Swedish participants had more positive affect, whereas Iranian participants ...

The aim of this study was to examine mutations in the quinolone-resistance-determining region (QRDR) of gyrA and parC genes in Pseudomonas aeruginosa isolates. A total of 100 clinical P. aeruginosa isolates were collected from different university-affiliated hospitals in Tabriz, Iran. Minimum inhibitory concentrations (MICs) of ciprofloxacin and levofloxacin were evaluated by agar dilution assay. DNA sequences of the QRDR of gyrA and parC were determined by the dideoxy chain termination method. Of ...

Recent technological developments in renewable energy systems and significant growth of solar and wind energy have made these 2 renewable sources potential viable alternatives for conventional energy sources. However, due to intermittent nature, their reliability and availability are not similar to traditional sources. Hence, it is crucial to estimate the solar and wind availability and contribution more accurately. There are various factors affecting the generation capacity of renewable sources. ...

The present paper deals with entropy generation study of CuO/water nanofluid flow over a spherical heat source that is installed inside a cylindrical channel with sudden expansion and contraction. To estimate the entropy generation rate; first, the governing equations are solved numerically to find the velocity and temperature fields in the domain where the flow is steady and laminar. Next, using the simulation data, the entropy generation number is calculated theoretically. The effects of nanofluid ...

Background: This randomized, parallel-group, non-blinded study was designed to determine the role of fibular fixation in the treatment outcomes of combined distal tibia and fibula fractures. Materials and Methods: Sixty patients with distal tibial and fibular fractures were randomly divided in two groups of case and controls. In the case group, fibula was fixed prior to the fixation of tibia. In the control group, tibia was fixed without fibular fixation. Primary outcomes were varus–valgus angulation, ...
