Abstract
Stevia rebaudiana is one of the most important biologically sourced and low-calorie sweeteners Bertoni that has a lot of steviol glycosides. Tissue culture is the best for propagation of stevia and micro nutrients can affect both morphological traits and steviol glycosides production. Therefore, the effect of different concentrations of KH2PO4on stevia growth factors and gene expression had been studied by tissue culture methods, RT-PCR and HPLC. According the results, bud numbers had increased significantly in MS + 0.034 mMKH2PO4 media and the highest measured length was seen in plants grown under MS + 0.034 mM KH2PO4 treatment. Also, the highest growth rate (1.396 mm/d) was observed in MS + 0.034 mMKH2PO4.The best concentration of KH2PO4 for expression of UGT74G1 was 0.00425mMand the best one for UGT76G1 expression was 0.017mM. Interestingly, the best media for both stevioside and rebaudioside A accumulation was 0.017mM KH2PO4containing media. There was positive correlation between the best media for gene expression and the best one for steviol glycosides production.

Abstract
Stevia rebaudiana Bertoni is a famous medicinal plant for its low calorific value compounds which are named steviol glycosides (SGs) and they are 150-300 times sweeter than sugar. Among various SGs, stevioside and rebaudioside A considered to be the main sweetening compounds. Soil salinity is one of the most essential stress in the world. Salinity affects the survival and yield of crops. In current study the effects of salinity and osmotic stress caused by different concentration of NaCl (0, 20, 40, 60 and 80 mM) on morphological traits, genes expressionand amount of both stevioside and rebaudioside Aunder in vitro conditions has been investigated. The morphological traits such as bud numbers, root numbers, shoot length (after 15 and 30 days) were evaluated. With increasing salinity, the values of all studied morphological traits decreased. To investigation of UGT74G1 and UGT76G1 genes expression that are involved in the synthesis of SGs, RT-PCR was done and there were significant differences between all media. The highest expression of both genes was observed in plantlets grown on MS media (with NaCl-free). Also, the lowest amounts of gene expression of the both genes were seen in MS+ 60 mM NaCl. Based on HPLC results, the highest amount of both stevioside and rebaudioside A were observed in plantlets grown in MS media (with NaCl-free). Finally, it can be concluded that stevia can survive under salt stress, but it has the best performance in the lower salinity.

Abstract
High quality DNA is essential for molecular research. Secondary metabolites can affect the quantity and quality DNA. In current research two DNA isolation methods including CTAB and Delaporta (protocols 1 & 2 respectively) were applied in three leave samples from Cotinus coggygria, Citrus sinensis and Genus juglans that their leaves are rich of secondary metabolites. We successfully isolated DNA from C. coggygria, C. sinensis and Genus Juglans using the two protocols described above. Good quality DNA was isolated from C. coggygria, C. sinensis and Genus Juglans using protocol 1, while protocol 2 failed to produce usable DNA from these sources. The highest amount of DNA (1.3-1.6) was obtained from them using protocol 1. As we discovered, procedure 1 may work better for plants with secondary metabolites.

Abstract
INTRODUCTION Hesperidin (HES), as the most abundant flavonoid existing in the citrus, is widely used by human daily. The radio-protective effects of Hesperidin have been confirmed in various measurement systems. This study aimed to evaluate the effects of Hesperidin on the changes in the apoptosis level and expression of apoptotic genes target (bax, bcl-2 and ration of bax/bcl-2) in the peripheral blood lymphocytes of male rats after gamma radiation. MATERIALS AND METHODS 64 male rats were divided into eight groups: Control, HES (100 mg/kg b.w, orally, 7 days), whole body irradiation with 2 and 8Gy, pre-administrated with 50 and 100 mg/kg body weight of Hesperidin for 7 days before irradiation with 2 and 8 Gy. 24 hours after radiation, apoptotic lymphocytes were evaluated using PE Annexin V Apoptosis detection I kit and the levels of mRNA for bax and bcl-2 were evaluated by real time reverse transcription polymerase chain reaction. RESULTS A significant reduction in apoptosis of the lymphocytes was demonstrated in group animals receiving 8 Gy compared to the group which received 2 Gy irradiation (p<0.0001). However, apoptosis significantly increased in group of rats who received Hesp before irradiation (p<0.05). The increase of apoptosis by Hesperidin administration can be attributed to the decreased expression of bax and significantly reduced expression of bcl-2 and finally increasing the ration of bax/bcl-2. CONCLUSION The results suggest that administration of 50 and 100 mg/kg of Hesperidin induces apoptotic effects by changing expression level of bax, bcl-2 and also the ratio of bax/bcl2.

Abstract
Periodontal disease is one of the most prevalent inflammatory illnesses and is a main cause of tooth loss in human population. Tumor necrosis factor-α (TNF-α) gene is one of pro-inflammatory cytokines which has important role in pathogenesis of periodontal disease. The main purpose of this study is to determine genotype abundance of TNF-α-1031 gene in both groups of patients and controls, and also investigation of relation of single nucleotide polymorphism (SNP) these genotypes with periodontal disease risk. DNA was extracted from blood tissue of 31 patients and 54 controls. The TNF-α-1031 polymorphism was evaluated by polymerase chain reaction- confronting two-pair primer (PCR-CTPP) method. In the GAP group, the frequencies of TT, TC and CC genotypes were 35.48%, 61.29 and 3.23%, respectively. In controls the frequencies of TT, TC and CC genotypes were 22.22%, 72.22%, and 5.56%, respectively. Results of this study showed that there was no significant association between TNF-α (-1031 T/C promoter) gene polymorphisms and the risk of generalized aggressive periodontitis disease.

Abstract
All organisms have Deoxyribonucleic acid (DNA) within their cells. DNA is a complex molecule that contains all of the information necessary to build and maintain an organism. DNA extraction is one of the most basic and essential techniques in the study of DNA that allow huge advances in molecular biology, biotechnology and bioinformatics laboratories. Whole blood samples are one of the main sources used to obtain DNA and there are many different protocols available in this issue. In current research, compared four DNA extraction protocols from blood samples; include modified phenol-chloroform protocol, two salting-out and enzyme free method and from commercial kit. The extracted DNAs by these protocols were analyzed according to their time demands, quality and quantity, toxicity and functionality in PCR method. Also the quality and quantity of the extracted DNA were surveyed by gel electrophoresis and Nanodrop spectrophotometry methods. It was observed that there are not significantly differences between these methods about DNA Purity (A260/A280), but the DNA yield (ng DNA/μl) of phenol/chloroform method was higher than other methods. In addition, phenol/chloroform was the most toxic method and it takes more time than other methods. Roche diagnostics GmbH kit was the most expensive among the four methods but the least extraction time was required and it was the safest method.

Abstract
The Helicobacter pylori is a Gram-negative, microaerophilic bacterium found usually in the stomach and use a number of mechanisms to survive in the stomach lumen. The presence of these bacteria in the stomach can lead to gastritis and reduction in stomach acid production. Acute inflammation can directly damage to the peripheral cells that are responsible for the secretion of acid. The risk of developing gastric carcinoma is associated to heterogeneity of Helicobacter pylori virulence factors. The HopQII is one of the outer membrane proteins involved in bacterial adherence to gastric mucosa and has been suggested to also play a role in the virulence of H. pylori. The purpose of the current study was to investigate the association between different H. pylori virulence hopQII allele and patients with gastroduodenal disorders. For this purpose 58 stomach biopsies of patients with gastric cancer and 100 saliva samples from healthy individuals were collected. Then genomic DNA was purified and PCR for was done for desired genes via specific primers. The H. pylori infections were diagnosed by PCR for GlmM gene. Then frequencies of hopQII+ and hopQII- genotypes was determined in H. pylori infected cases. Statistical analysis showed that there were not significant differences between healthy and diseased ones for genotype hopQII+.

Abstract
Generalized aggressive periodontitis (GAP) is a subtype of periodontal diseases that characterized by rapid destruction of periodontal supporting tissues. The MnSOD Val-9Ala mutation of manganese superoxide dismutase gene (MnSOD Val-9Ala) and its correlation with periodontal diseases has been studied in different populations. The purpose of this study was to investigate the possible association of MnSODVal-9Ala polymorphism with periodontitis disease in sample of GAP patients in Iran for the first time. Following a GAP examination, 50 GAP patients and 100 healthy individuals were recruited. Genomic DNA was extracted from peripheral blood leukocytes and the MnSODVal-9Ala polymorphismwas detected using PCR-RFLP method. The frequency of Ala/Ala, Ala/Val and Val/Val genotypes in healthy individuals were 25, 66 and 9%, respectively. In periodontitis patients, frequencies were as Ala/Ala (12%), Ala/Val (50%) and Val/Val (38%) genotypes. There was a significant positive association between distribution of MnSOD Val-9Ala genotypes and the risk of periodontitis disease (p<0.05). Our results indicated that MnSOD Val-9Ala gene polymorphism has a positive association with the risk of periodontitis disease.

Abstract
BACKGROUND Despite numerous studies over a decade, it still remains controversial about the biological effects of RF EMF emitted by mobile phone telephony. OBJECTIVE Here we investigated the effect of 900 MHz GSM on the induction of oxidative stress and the level of intracellular reactive oxygen species (ROS) in human mononuclear cells, monocytes and lymphocytes as defence system cells. METHOD 6 ml Peripheral Blood samples were obtained from 13 healthy volunteers (21-30 year-old). Each sample was devided into 2 groups: one was exposed RF radiation emitted from a mobile phone simulator for 2 hour and the other used as control group which was not exposed to any fields. After that, mononuclear cells were isolated from peripheral blood by density gradient centrifugation in Ficoll-Paque. The intracellular ROS content in monocytes and lymphocytes was measured by the CM-H2DCFDA fluorescence probe using flowcytometry technique. RESULTS Our results showed significant increase in ROS production after exposure in population rich in monocytes. This effect was not significant in population rich in lymphocytes in comparison with non exposed cells. CONCLUSION The results obtained in this study clearly showed the oxidative stress induction capability of RF electromagnetic field in the portion of PBMCs mostly in monocytes, like the case of exposure to micro organisms, although the advantages or disadvantages of this effect should be evaluated.

Abstract
In this study, an Euler–Lagrange coupling two-phase flow model, namely movable bed simulator (MBS)-two-dimensional (2D) model was employed to explore the current-induced live-bed scour beneath marine pipelines. The fluid phase characteristics, such as velocity and pressure, were obtained by the Reynolds-averaged Navier–Stokes (RANS) equations with a k-ε turbulence closure model in a two-dimensional Eulerian grid, whereas the seabed beneath pipelines was traced as an assembly of discrete sand grains from the Lagrangian point of view. The live-bed scour was evolved as the motion of a granular media based on distinct element method (DEM) formulation, in which the frequent interparticle collision was described with a spring and dashpot system. The fluid flow was coupled to the sediment phase, considering the acting drag forces between. Comparison between the numerical result and experimental measurement confirms that the numerical model successfully estimates the bed profile and flow velocity field. It is evident that the fluid shear stress decreases with the increasing of gap ratio e/D. The numerical model provides a useful approach to improve mechanistic understanding of hydrodynamic and sediment transport in live-bed scour beneath a marine pipeline.

Abstract
Cisplatin is one of the most widely prescribed chemotherapy drugs to treat different types of cancers. However, this anticancer drug has a number of side effects such as kidney and nerve damages, anaphylactic reactions, hearing loss, nausea, and vomiting that strongly restrict its function. In the present study, single-walled carbon nanotubes (SWCNTs) are used as protective drug carriers which can decrease these severe side effects to some extent. Using the hybrid discrete-continuum model in conjunction with Lennard-Jones potential, new semi-analytical expressions in terms of single integrals are given to evaluate van der Waals (vdW) potential energy and interaction force between an offset cisplatin and a SWCNT. In addition, molecular dynamics (MD) simulations are conducted to validate the results of such a hybrid approach. The preferred location and orientation of cisplatin while entering SWCNTs are determined. It is shown that the equilibrium condition of the drug may be affected by the radius of nanotube, the orientation of cisplatin, and the distance between the central molecule of the drug (Pt) and the left end of nanotube. Furthermore, the influence of equilibrium condition on the distributions of vdW interactions is investigated.
