Abstract
The enzymes serine hydroxymethyltransferase 1 (SHMT1) regulate key reaction in folate-mediated one-carbon metabolism. In the current study we aimed to examine the possible association between SHMT1 gene polymorphisms and childhood acute lymphoblastic leukemia (ALL) in a sample of Iranian population. The rs9901160, rs2273027, rs9909104, rs1979277, and rs11868708 gene polymorphisms of SHMT1 were genotyped in 120 children diagnosed with ALL and 120 healthy children by the polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). The results showed that rs9901160, rs2273027 as well as rs1979277 polymorphism significantly increased the risk of childhood ALL (P<0.05). While, rs9909104 polymorphism significantly decreased the ALL risk (P<0.05). The rs11868708 variant was not associated with risk/protection of childhood ALL (P>0.05). In conclusion, our results suggest that the polymorphisms of SHMT1 gene are associated with childhood ALL risk in a sample of Iranian population. Further studies with larger sample sizes and different ethnicities are necessary to verify our findings.

Abstract
Interleukin-18 (IL-18) plays a critical role in immune response, contributing to the pathogenesis and pathophysiology of infectious diseases. Polymorphisms in the IL-18 genes are known to influence expression levels and may be associated with outcome of infections. The objective of this study was to determine whether the presence of IL-18 polymorphisms –607 A/C (rs1946518) was associated with tuberculosis disease. We investigated the functional polymorphism of IL-18 (rs1946518) in 174 patients with pulmonary tuberculosis (PTB) and 177 healthy subjects. Genotype analysis was done using tetra amplification refractory mutation system-PCR (T-ARMS-PCR). The allelic and genotypic frequencies of the IL-18 polymorphism did not differ significantly between PTB and the controls. Our finding suggests that IL-18 polymorphism (rs1946518) may not be a risk factor for susceptibility to tuberculosis in a sample of Iranian population. Further studies are required to validate our findings.

Abstract
Introduction: This study compared the efficacy of Aryoseven with Novoseven to control bleeding episodes in patients with hemophilia A with inhibitors. Methods: Sixty-six patients were randomized into 2 groups, with 4 consecutive block randomization. These groups received Aryoseven and Novoseven dosages of 90 to 120 μg/kg intravenously every 2 hours. Results: Median (interquartile range) level of factor VIII (FVIII) inhibitor in groups A and B was 15.0 and 19.0 Bethesda Unit (BU) preadministration. Bleeding onset in group A was 1246 ± 1104 minutes and in group B was 2301 ± 1693 minutes ( P = .311). The Kavakli global response scores and treatment success rate was comparable in both the groups. The side effects in groups A (9.7%) and B (2.9%) were comparable. Conclusion: Biosimilar recombinant activated FVII is found to be as effective as Novoseven in the treatment of acute joint bleeding in patients with hemophilia with inhibitors. Its usage will decrease the gaps in hemophilia.

Abstract
In order to establish the efficacy and biosimilar nature of AryoSeven to NovoSeven in the treatment of congenital factor VII (FVII) deficiency, patients received either agent at 30 μg/kg, intravenously per week for 4 weeks, in a randomized fashion. The primary aim was to compare FVII:coagulation activity (FVII:C), 20 minutes after recombinant activated FVII (rFVIIa) injection, in the 2 groups. A secondary measure was self-reported bleeding. The median interquartile baseline range of the plasma level of activated FVII (FVIIa) activity in the 2 groups was 1.6 (1.1-14.0) IU/dL and 5.0 (1.1-25.5) IU/dL. All patients achieved levels of FVIIa (FVII:C) >30 IU/dL, 20 minutes after the injection of rFVIIa. Bleeding was similar between the 2 groups, with a comparable decrease in severity and frequency compared to the last month prior to treatment. AryoSeven is similar to NovoSeven in increasing postinjection FVIIa activity as well as in clinical safety and efficacy.

Abstract
OBJECTIVE To evaluate the possible association between cathepsin Z (CTSZ) rs34069356 C/T (Ala286Thr) and melanocortin-3 receptor (MC3R) rs6127698 G>T (-484 G/T) gene polymorphisms and pulmonary tuberculosis (PTB) in an Iranian sample population. DESIGN This case-control study included 150 PTB patients and 177 healthy subjects. Tetra amplification refractory mutation system-polymerase chain reaction was used to detect polymorphisms. RESULTS Our findings revealed that the MC3R rs6127698 TT genotype increased the risk of PTB compared with GG (additive model: OR 2.24, 95%CI 1.13-4.64, P = 0.021) as well as GG+GT (recessive model: OR 1.89, 95%CI 1.13-3.18, P = 0.016). The rs6127698 T allele increased the risk of PTB (OR 1.56, 95%CI 1.14-2.13, P = 0.005) compared to the G allele. The CTSZ rs34069356 polymorphism was not associated with PTB in additive-, dominant- and recessive-tested inheritance models (P > 0.05). CONCLUSION Our data suggest that MC3R rs6127698, but not CTSZ rs34069356 polymorphism, is associated with PTB in a sample Iranian population.

Abstract
Hepatitis C virus (HCV) chronic infection is a worldwide health problem, and numerous efforts have been invested to develop novel vaccines. An efficient vaccine requires broad immune response induction against viral proteins. To achieve this goal, we constructed a DNA vaccine expressing nonstructural 3 (NS3) gene (pcDNA3.1-HCV-NS3) and assessed the immune response in C57BL/6 mice. In this study, the NS3 gene was amplified with a nested-reverse transcriptase-polymerase chain reaction (RT-PCR) method using sera of HCV-infected patients with genotype 1a. The resulting NS3 gene was subcloned into a pcDNA3.1 eukaryotic expression vector, and gene expression was detected by western blot. The resultant DNA vaccine was co-administered with interleukin-12 (IL-12) as an adjuvant to female C57BL/6 mice. After the final immunizations, lymphocyte proliferation, cytotoxicity, and cytokine levels were assessed to measure immune responses. Our data suggest that co-administration of HCV NS3 DNA vaccine with IL-12 induces production of significant levels of both IL-4 and interferon (IFN)-γ (p<0.05). Cytotoxicity and lymphocyte proliferation responses of vaccinated mice were significantly increased compared to control (p<0.05). Collectively, our results demonstrated that co-administration of HCV NS3 and IL-12 displayed strong immunogenicity in a murine model.

Abstract
Factor XIII or "fibrin-stabilizing factor," is a transglutaminase circulates in the blood circulation as a hetero tetramer with two catalytic A subunits and two carrier B subunits. This important coagulation factor has a crucial role in clotting cascade and produces strong covalent bonds between soluble formed fibrin monomers during coagulation. This stable cross linked fibrin strands are resistanttodegradationby thefibrinolyticsystem that enablesthe bodyto stoppotential bleeding episodes. In the absence or severe decrease of factor XIII, although the clot is formed, but is rapidly degraded by the fibrinolytic system, and delayed bleedingoccurs.Factor XIII deficiency is an extremely rare bleeding disorder with estimated incidence of 1/2-3000, 000 in the general population. Presumptive diagnosis of factor XIII deficiency was by clot solubility test in 5M urea or 1% monochloroacetic acid environments. In patients with abnormal screening clot solubility test, the disease can be confirmedbymore specifictestssuch as quantitative factor XIII activity assay andFXIIIAgassay.After diagnosis of disease all patients with severe factor XIII deficiency(<1 U/dl) shouldreceive prophylactic substitution therapywith fresh frozen plasma (FFP) and cryoprecipitate as traditional choices or purified concentrateof blood coagulation factor XIII (Fibrogammin P) inorder to control severe and life-threatening clinical complications of factor XIII deficiency.

Abstract
The aim of this study was to investigate the effect of processing route (i.e., quench cooling and ball milling) on the surface energy heterogeneity and surface chemistry of indomethacin (IMC). Recently developed inverse gas chromatography (IGC) methodology at finite concentrations was employed to determine the surface energy distributions of crystalline, quench cooled and milled IMC samples. Surface properties of crystalline and processed IMC were measurably different as determined by the IGC and other conventional characterization techniques: differential scanning calorimetry and powder X-ray diffraction. Quench cooled IMC was in fully amorphous form. Milled IMC showed no amorphous character by calorimetric or X-ray diffraction studies. It was demonstrated that both processed IMC samples were energetically more active than the crystalline IMC. In particular, milled IMC exhibited a relatively higher dispersive surface energy and higher surface basicity (electron donor capability). This may be attributed to the creation of surface defect sites or exposure of higher energy crystal facets during the milling process. This study confirms that processing route has notable influence on the surface energy distribution and surface acid-base character. IGC was demonstrated as a powerful technique for investigating surface properties of real-world, heterogeneous pharmaceutical materials.

Abstract
BACKGROUND Thalassemia is the most common monogenic disease in South-East of Iran. Despite the 70% reduction in Iranian thalassemia cases after thalassemia control comprehensive program, 601 affected babies were born in Sistan and Balouchistan Province, Iran from 2002 to 2010, so this study aims at investigating the causes of new thalassemia cases. METHODS Data from this retrospective cross-sectional study was collected through interviews and information in the patients' hospital records. RESULTS Data revealed that 52.4% of fathers and 78.4% of mothers of thalassemic children had elementary education or less. In addition, 78.6% of the couples did not undergo premarital screening for thalassemia and 71.2% of the couples were not notified of their own minor thalassemia until a child was born with major thalassemia. Of the diagnosed minor couples, about 25% did PND and the others did not carry out because mothers were unaware of proper gestational age and of the importance of this issue, financial problems, and the husbands' disagreement to take the tests. Moreover, 16 mothers, in spite of being diagnosed of having a major fetus, refused to terminate the pregnancy. CONCLUSION The most preventable causes for affected births include couples' unawareness of being minor and unawares of the PND importance and process.

Abstract
The protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, which encodes an intracellular lymphoid-specific phosphatase, is considered an important regulator of T-cell activation. We investigated a possible association between the PTPN22 C1858T (R620W) polymorphism and pulmonary tuberculosis in an Iranian population. Single nucleotide polymorphisms of PTPN22 C1858T (rs2476601) were genotyped in 172 pulmonary tuberculosis cases and 204 normal subjects from Zaheden, Iran. Frequencies of genotypes CC, CT and TT of the PTPN22 C1858T polymorphism were 98.3, 1.7 and 0% in the pulmonary tuberculosis patients, and 96.1, 3.9 and 0% in the control group, respectively (P = 0.239). The frequency of the minor (T) allele was 0.8% in pulmonary tuberculosis patients and 2.0% in controls. Significant differences were not observed in genotype or allele frequencies of PTPN22 C1858T in the comparison between pulmonary tuberculosis patients and healthy subjects in our Iranian population sample.

Abstract
OBJECTIVE To determine the molecular spectrum of β-thalassemia mutations among at-risk Balouch couples in Iran. METHODS Mutations' detection in DNAs extracted from the blood of partners of at-risk couples was characterized, and chorion villus sampling by amplification refractory mutation system and DNA sequencing was performed. Fetal diagnosis was also confirmed by linkage analysis. RESULTS Out of a total of 1234 at-risk Balouch couples referred to the center for prenatal diagnosis (PND) from June 2002 to June 2010, a high percentage of '67.4%' were from consanguineous marriages and 37.4% had between one and four affected children. The trend in referring gradually increased from 34 cases in 2002 to 357 cases in 2010. The astonishing finding was that, unlike most previous studies, only IVS 1-5 with an unusual frequency of 87.20% along with codon 8/9 (+G) with 4% constitutes about 91% of mutations. Altogether, 729 PNDs were made in 583 couples, 25% of whom had over one PND, and surprisingly five PNDs were made in the same woman within just 8 years. CONCLUSION Regarding the limited types of frequent mutations among Balouch population, it is hopefully believed that the incidence of β-thalassemia could be controlled by a correct diagnosis in the due time.

Abstract
Concerning the key role of interferon-γ (IFN-γ) in the protective immunity against Mycobacterium tuberculosis, we aimed to find the possible association between single nucleotide polymorphism of IFN-γ +874T/A (rs61923114) and pulmonary tuberculosis (PTB). This case-control study was performed on 142 PTB patients and 166 healthy subjects. Genotype analysis was done using amplification refractory mutation system-PCR (ARMS-PCR). We found that the AA genotype of +874A/T IFN-γ is a risk factor for PTB (OR = 3.333, 95% CI = 1.537-7.236, p=0.002). The results showed that the +874A allele frequency was higher in PTB than in normal subjects (OR = 1.561, 95% CI = 1.134-2.480, p=0.007). In conclusion, significant association was found between the IFN-γ +874T/A polymorphism (rs61923114) and susceptibility to PTB in a sample of Iranian population.

Abstract
Approximately 5-10% of subjects infected with Mycobacterium tuberculosis develop active tuberculosis. It has been proposed that genetic factors determine the host's vulnerability to tuberculosis. Chemokine (C-C motif) ligand 2 (CCL2), commonly known as monocyte chemoattractant protein-1 (MCP-1), plays a key role in protective immunity against M. tuberculosis. The present study was aimed to determine if there was an association between -2581 A/G single nucleotide polymorphism of CCL2 and pulmonary tuberculosis (PTB) in a sample of Iranian subjects. This case-control study was performed on 142 PTB and 166 healthy subjects. The polymorphism of CCL2 (rs1024611) was determined using tetra amplification refractory mutational system-polymerase chain reaction (tetra ARMS-PCR). There were no significant differences between PTB patients and control subjects regarding -2581 A/G single nucleotide polymorphism of CCL2. In conclusion, our results do not support an association of -2581 A/G polymorphism of CCL2 with PTB susceptibility.

Abstract
PURPOSE OF THE STUDY to determine the efficacy, adverse effects and safety of a new Iranian generic product of deferasirox (Osveral®) in Iranian transfusion dependent major thalassemic (TD-MT) patients. METHODS In 9 main thalassemia treatment centers, all of TD-MT patients (aged ≥2 yrs) with serum ferritin (SF) levels≥1000 ng/ml, or >100 ml/kg of RBC transfusion,who could not tolerate parental iron chelating were recruited regardless of their previous iron chelation therapy. Periodical clinical and laboratory evaluations were conducted for adverse effects (AEs). Primary efficacy end point was Mean of Relative Change of Serum Ferritin (MRC-SF) from the baseline level during one year. Analysis of variance (ANOVA), t test, chi-square or Fisher exact test were used for statistic analysis appropriately (P values <0.05 were considered as statistical significant). RESULTS In 407 cases the male/female ratio was 0.98. Mean age was 11.5±7.4 (2-58) years. The mean of initiating dose of Osveral® and mean usage dose during the study was 23.5±4.9 mg/kg and 24.9±4.9 mg/kg respectively. MRC-SF was -11.44% ±38.92 and it showed significant decline in SF (P value<0.001) one hundred and forty eight patients out of 407 patients experienced at least one. AE, the most common of them were transient increase in serum creatinin (97;24.1%) and>5 time increase in transaminases (24;5.89%).The causes of discontinuation of treatment were non-satisfactory treatment ( 24; 5.8%), poor or non-compliance of patients (21;5.1%), and adverse effects (13; 3.1%) CONCLUSION A detailed comparison with similar studies on deferasirox (Exjade®) shows a promising efficacy and safety for its Iranian generic product (Osveral ®).

Abstract
Entropy production during the fatigue process can serve as a measure of degradation. We postulate that the thermodynamic entropy of metals undergoing repeated cyclic load reaching the point of fracture is a constant, independent of geometry, load and frequency. That is, the necessary and sufficient condition for the final fracture of a metal undergoing fatigue load corresponds to a constant irreversible entropy gain. To examine validity, we present the results of an extensive set of both experimental tests and analytical predictions that involve bending, torsion and tension-compression of aluminium 6061-T6 and stainless steel 304 specimens. The concept of tallying up the entropy generation has application in determining the fatigue life of components undergoing cyclic bending, torsion and tension-compression.
