Abstract
Soil and ground water resource pollution by petroleum compounds and chemical solvents has multiple negative environmental impacts. The aim of this research was to investigate the impacts of kerosene and gas oil pollutants on some physical and chemical properties, breakthrough curve (BTC), and water retention curve (SWRC) of silty clay soil during a 3-month period. Therefore, some water-saturated soils were artificially contaminated in the pulse condition inside some glassy cylinders by applying half and one pore volume of these pollutants, and then parametric investigations of the SWRC were performed using RETC software for Van Genukhten and Brooks-Corey equations in the various suctions and the soil properties were determined before and after pollution during 3 months. The results showed that gas oil and kerosene had a slight effect on soil pH and caused the cumulative enhancement in the soil respiration, increase in the bulk density and organic matter, and reduction in the soil porosity and electrical and saturated hydraulic conductivity. Furthermore, gas oil retention was significantly more than kerosene (almost 40%) in the soil. The survey of SWRC indicated that the contaminated soil samples had a little higher amount of moisture retention (just under 15% in most cases) compared to the unpolluted ones during this 3-month period. The parametric analysis of SWRC demonstrated an increase in the saturated water content, Θ s, from nearly 49% in the control sample to just under 53% in the polluted ones. Contaminants not only decreased the residual water content, Θ r, but also reduced the SWRC gradient, n, and amount of α parameter. The evaluation of both equations revealed more accurate prediction of SWRC's parameters by Van Genukhten compared to those of Brooks and Corey.

Abstract
Nonsyndromic cleft lip with or without palate (CL/P) is thought to be caused by the interplay of genetic and environmental factors, and this has thus hindered the process of identifying genetic causative factors. Numerous studies in the past decade have implicated IRF6 in CL/P, but this has not often been replicated in other populations. In specific, the only etiologic single-nucleotide polymorphism (SNP) identified in the IRF6 locus (rs642961) has recently been shown not to be associated with CL/P in diverse populations. We therefore used a genewide tagging SNP (tagSNP) haplotyping approach (including rs642961 as a tagSNP) to detect all potential risk-conferring haplotypes and combined this with detailed subphenotyping of CL/P cases ( N = 150) according to severity. We observed a significant overrepresentation of a tagSNP haplotype carrying the rs642961 risk allele in the most severe subphenotype of CL/P (complete bilateral CL/P; P = 0.008, odds ratio = 4.97, 95% confidence interval = 1.33 to 18.46). It was recently shown that >80% of IRF6 mutations in syndromic CL/P occur on the same haplotype background. We therefore suggest that IRF6 is a marker of CL/P severity.

Abstract
BACKGROUND Bone healing and its reconstruction in fractures, especially in long bones are of particular importance in regenerative medicine. This study compares the bone healing rate after a human xenograft of mineralized bone and together with an allograft of bone marrow mesenchymal stem cells (MSCs) in an experimental tibial bone fracture rabbit model. METHODS In fall 2009, twenty New Zealand white rabbits were randomly divided into 2 equal groups. In both groups, a 5 mm segmental defect was created in the right tibia. In group A, a scaffold pin was seeded with allogenic rabbit MSCs and was placed in the defect area and in group B, the defect was filled with an unseeded pin human mineralized bone xenograft. An untreated defect was induced in the left tibia of all animals serving as the control. After 4-8 weeks, the segmental defects were histologically evaluated and also by a compressive test. RESULTS In groups A and B, healing and formation of new bony tissue were significantly more than the control group and with a significant less inflammation. CONCLUSION Tissue engineering of mineralized bone xenograft and MSCs allograft may be significant steps in bone healing and regenerative medicine.

Abstract
BACKGROUND Finding more efficient agents with fewer side effects for treatment of burns has always been a concern for researchers. Silver sulfadiazine (SSD), apparently due to its antimicrobial effect, is still one of the most common prescribed agents. Previous studies suggested that Arnebia euchroma (AE) has shown antimicrobial and anti-inflammatory activities. This study investigates the healing effect of AE extract in comparison with SSD in second degree burn wounds. METHODS Fort eight female Wistar rats (220±20 g) were divided into four groups. Standard second degree burn wounds were induced on the back of their necks. One group was treated with SSD; two groups were treated with AE cream at concentrations of 10% (AE10) and 20% (AE20) and the control group which received no treatment. The duration of treatment was 28 days. RESULTS This study revealed that AE and SSD noticeably improved re-epithelization, fibroblasts proliferation, and collagen bundle synthesis and had a noticeable anti-inflammatory effect compared with the control group. CONCLUSION Results of the present study revealed that Arnebia euchroma herbal extract was an effective treatment for second degree burn wounds when compared with SSD.

Abstract
An antigen-based ELISA system was evaluated for diagnosis of visceral leishmaniasis (VL). Urine samples from confirmed VL cases were tested by the system in comparison with urine samples from patients with non-VL infectious disease and patients with non-infectious diseases. Antigen was detected in urine of 21 out of 35 (60%) of VL cases. No cross reaction was found with samples from healthy individuals except in 3 samples from non-VL infectious diseases. Two samples from cutaneous leishmaniasis patient and one from patient with toxoplasmosis. The results obtained with the antigen-based ELISA were compared to those obtained with direct agglutination test (DAT), an antibody-based ELISA and indirect immunofluorescent antibody (IFA) revealed that the antigen-based ELISA is comparable in terms of specificity (91.2%; 95% CI=75.2-97.7%) but with a lower sensitivity (60%; 95% CI=42.2-75.6%). These results suggest that the antigen detection in urine by the noninvasive antigen-based ELISA system might offer a useful method for diagnosis of VL.

Abstract
The study was conducted to determine the effect of Azotobacter chroococcum (Azotobacter) application on quality and quantity forage of the rapeseed cultivars (RGS 003, Hyolla 401 and Hyolla 330) and the possibility of cultivation the rapeseed forage in summer. The experimental design was spilt plot laid out in randomized complete block with three replications. Different levels of Azotobacter (zero and one kg hal) and cultivars were randomized to main plot and sub plot units, respectively. Results showed that Azotobacter significantly affected on all quantity traits except plant height. There were significant differences among cultivars for dry matter, biomass, sub branch number, plant height and forage glucosinolate concentration. Therefore Azotobacter can be considered as growth promoting for rapeseed in the future studies. Also, RGS003 cultivar was better than other cultivars when Azotobacter was applied.

Abstract
1. The aim of present study was to investigate the effects of magnesium (Mg) on cardiac function and infarct size and to compare it effects with those of adenosine. The mechanism of Mg-mediated cardioprotection was explored by combined use of Mg and a selective adenosine A(1) receptor antagonist. 2. Rat isolated hearts were used for Langendorff perfusion. Hearts were either non-preconditioned or preconditioned with Mg (6 mmol/L) or adenosine (1 mmol/L) before 30 min sustained ischaemia followed by 120 min reperfusion. Within each of these protocols, hearts were divided into two groups; one group was exposed to the A(1) receptor antagonist 8-cyclopentyl-1,3-dipropylxanthine (DPCPX; 200 nmol/L). Infarct size was measured by the triphenyltetrazolium chloride method. Left ventricular function was assessed by left ventricular developed pressure (LVDP), the product of heart rate x LVDP and coronary flow (CF). 3. The administration of Mg had an anti-infarct effect independent of its effect on postischaemic functional recovery in rats. Both Mg and adenosine equipotently reduced infarct size, but this effect of Mg was not blocked by the simultaneous administration of DPCPX. Cardiac function was improved by both adenosine and Mg and blockade of adenosine A(1) receptors attenuated these effects for both agents. 4. In conclusion, the results of the present study indicate that stimulation of adenosine A(1) receptors is not responsible for the anti-infarct effect of Mg in ischaemic myocardium in rats, but that the Mg-mediated protection of postischaemic functional recovery in rats is mediated by these receptors.

Abstract
In this study, the feasibility and engineering aspects of acidophilic ferrous iron oxidation in a continuous biofilm airlift reactor inoculated with a mixed culture of Acidithiobacillus ferrooxidans and Leptospirillum ferrooxidans bacteria were investigated. Specific attention was paid to biofilm formation, competition between both types of bacteria, ferrous iron oxidation rate, and gas liquid mass transfer limitations. The reactor was operated at a constant temperature of 30 degrees C and at pH values of 0-1.8. Startup of the reactor was performed with basalt carrier material. During the experiments the basalt was slowly removed and the ferric iron precipitates formed served as a biofilm carrier. These precipitates have highly suitable characteristics as a carrier material for the immobilization of ferrous iron-oxidizing bacteria and dense conglomerates were observed. Lowering the pH (0.6-1) resulted in dissolution of the ferric precipitates and induced granular sludge formation. The maximum ferrous iron oxidation rate achieved in this study was about 145 molFe(2+)/m(3).h at a hydraulic residence time of 0.25 h. Optimal treatment performance was obtained at a loading rate of 100 mol/m(3).h at a conversion efficiency as high as 98%. Fluorescent in situ hybridization (FISH) studies showed that when the reactor was operated at high ferrous iron conversion (>85%) for 1 month, the desirable L. ferrooxidans species could out-compete A. ferrooxidans due to the low Fe(2+) and high Fe(3+) concentrations.
