Abstract
BACKGROUND The androgen receptor (AR) has been studied as an approach to cancer therapy. AIMS We used human breast cancer-derived cells with high, low, and very low expression levels of AR, in addition to prostate cancer-derived LNCaP and DU-145 cells as a positive and negative controls to examine apoptosis caused by a synthetic peptide that targets ARs. METHODS AND RESULTS The peptide was produced to inhibit AR transactivation in breast cancer cell lines. We then measured cell viability, caspase-3 activity, and the ratio of Bax/Bcl-2. The findings indicated that the peptide (100-500 nM) in the presence of dihydrotestosterone (DHT) reduced cell growth in cells with high and low expression level of AR (p < .001), but not in cells with very low levels of AR. Treatment with 100-500 nM of peptide activated caspase-3 and increased the ratio of Bax/Bcl-2 in cells with high and low expression levels of AR. Also, increasing concentrations of the peptide (100-500 nM) reduced BrdU incorporation in the presence of DHT and promoted apoptosis in cells with high and low expression levels of AR (p < .001). CONCLUSION The findings indicate the peptide significantly increased apoptosis in cancer cells.

Abstract
The influenza H1N1 virus is the causative agent of the flu pandemic in the world. Due to the shortage of effective means of control, it is remained the serious threats to public and avian health. To battle the surge of viral outbreaks, new treatments are crucially needed. The viral RNA polymerase, which is responsible for transcription and replication of the RNA genome, is comprised of subunits PA, PB1 and PB2. PA has endonuclease activity and is a well known target for inhibitor and drug design. In the current study, we employed molecular docking, molecular dynamics (MD), MMPBSA, QMMM and ADME studies to find and propose an inhibitor among 11,873 structures against PA. Our molecular docking, MD, MMPBSA and QMMM studies showed that ZINC15340668 has ideal characteristics as a potent PA inhibitor, and can be used in experimental phase and further development. Also, ADME prediction demonstrated that all physico-chemical parameters are within the acceptable range defined for human use. Molecular mechanism based study revealed that upon inhibitor binding; the flexibility of PA backbone is increased. This observation demonstrates the plasticity of PA active site, and it should be noticed in drug design against PA Influenza A viruses. In the final phase of the study, the efficiency of our proposed hit was tested computationally against mutant drug resistant I38T_PA. Our results exhibited that the hit inhibits the I38T_PA in different manner with high potency.

Abstract
Objectives Organ-specific hemosiderosis and iron overload complications are more serious and more frequent in some patients with beta thalassemia major (BTM) compared with others. We investigated whether coinheritance of HFE H63D or C282Y gene mutations in patients with BTM contributes to the phenotypic variation of iron overload complications and assessed the correlation of cardiac and hepatic hemosiderosis with plasma ferritin levels. Methods We studied 60 patients with BTM with a mean age of 17.5±9.1 years from the Northwest of Iran. HFE gene mutations were analyzed using the polymerase chain reaction-restriction fragment length polymorphism method. Cardiac and hepatic hemosiderosis was assessed using T2*magnetic resonance imaging (MRI). Ferritin levels were measured using the enzyme immunoassay method. Results Ferritin levels showed a strong inverse correlation with hepatic T2*MRI values (r = -0.631, p = 0.001) but a poor correlation with cardiac T2*MRI values (r = -0.297, p = 0.044). The correlation between cardiac T2*MRI values and hepatic T2*MRI values was poor and insignificant (r = 0.287, p = 0.058). Genotype and allele distribution of HFE H63D and C282Y mutation did not differ significantly between patients with and without hepatic or cardiac hemosiderosis (p > 0.050). However, carriers of HFE 63D allele had significantly higher ferritin levels compared with non-carriers (1 903±993 vs. 992±683, p < 0.001). Conclusions Cardiac T2*MRI values showed a poor correlation with hepatic T2*MRI values and ferritin levels. Accurate assessment of cardiac iron overload in patients with BTM can only be done using the T2*MRI technique. Additionally, HFE H63D is a significant determinant factor for elevated ferritin levels in BTM patients.

Abstract
Background: Thalassemia is one of the most common monogenic disorders characterized by reduced production of globin chains. Although regular red blood cell (RBC) transfusion support is the main treatment for these patients, it may be associated with complications such as RBC alloimmunization. Aim: The study aimed to determine the incidence of alloimmunization and autoimmunization to RBC antigens in β-thalassemia major patients from Zanjan, Zanjan Province, Iran. Materials and Methods: A total of 49 β-thalassemia major patients comprising 24 females and 25 males (mean age: 18.59 ± 8.16 years; range: 2-40 years) from Northwest Iran were included in a cross-sectional study. Alloantibody screening and identification were done using 3-cell and 10-cell reagent red blood cells, respectively. Autoantibody detection was performed using direct Coomb's test. Results: The incidence of alloimmunization was 16.32% with 10 alloantibodies identified in 8 patients. The most common clinically significant alloantibody identified in alloimmunized patients was anti-Kell (K-antigen) (60%) followed by anti-Rhesus (Rh) (E, c-antigens). The rate of alloimmunization was significantly lower in patients transfused with leukoreduced RBCs compared with those transfused with nonleukoreduced RBCs (9.53% vs 57.14%, P = 0.001). There was no significant correlation between alloantibody formation and the age, gender, hemoglobin levels, number of transfused units, and splenectomy. Conclusion: Transfusion of leukoreduced and phenotypically matched red blood cells for Kell (K) and Rh (E, c) antigens may help reduce the alloimmunization rate in Iranian β-thalassemia major patients. Moreover, autoimmunization to RBC antigens was rare in our patients.

Abstract
Severe thrombocytopenia with bleeding is rarely reported in children with brucellosis, and recurrent epistaxis is extremely rare. Brucellosis with hemorrhage should be differentiated from viral hemorrhagic fever, malignancy, and other blood disorders. Bone marrow aspiration (BMA) is mandatory to differentiate from other blood diseases. An 8-year-old boy was admitted with recurrent epistaxis, petechiae and purpura on face and extremities and bleeding from the gums. During the hospitalization, he was febrile and complained of muscle pain. Leukopenias associated with thrombocytopenia were observed. BMA showed to be normal. Among the multiple tests requested, only serum agglutination test (SAT) and 2-MercaptoEthanol test (2-ME) were positive. He was treated with Intravenous immunoglobulin (IVIG) associated with co-trimoxazole and rifampin. Finally, fever subsided, and he was discharged with good condition and normal platelet count. Brucellosis should be a differential diagnosis in patients with fever and bleeding disorders and a history of consumption of unpasteurized dairy, in endemic areas.

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
BACKGROUND Though regular blood transfusion improves the overall survival of patients with beta-thalassemia, it carries a definite risk of infection with blood-borne viruses. We carried out this multicenter study to provide epidemiologic data on hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection among Iranian beta-thalassemic patients. Moreover, HCV infection-associated risk factors were investigated in this population. METHODS Seven hundred and thirty-two patients with beta-thalassemia major or beta-thalassemia intermedia, selected from five provinces of Iran including Tehran (n = 410), Kerman (n = 100), Qazvin (n = 95), Semnan (n = 81), and Zanjan (n = 46), were enrolled in this study. Using ELISA, their sera were tested for HBsAg, HBcAb, HBsAb, HCVAb, and HIVAb. The positive HCVAb results were confirmed by RIBA-2nd generation. RESULTS The study sample consisted of 413 males and 319 females, with a mean +/- SD age of 17.9 +/- 9.0 years. One hundred forty-one (19.3%) patients were HCVAb positive; 11 (1.5%) were HBsAg positive. No one was HIVAb positive. Univariate analysis showed that beta-thalassemia major (P = 0.01), older age (P = 0.001), longer transfusion duration (P = 0.000), HBsAg seropositivity (P = 0.03), and higher serum ferritin level (P = 0.002) were significantly associated with a higher prevalence of HCV. Furthermore, the prevalence of HCV infection dropped significantly after the implementation of blood donors screening (22.8% vs. 2.6%; P = 0.000). Using multivariate analysis, beta-thalassemia major (P = 0.002), age (P < 0.001), serum ferritin level (P < 0.001), as well as consumption of unscreened blood (P = 0.003), were independent factors associated with HCV infection. CONCLUSION The prevalence of HCV infection is much higher among Iranian beta-thalassemic patients as compared with HBV and HIV infections. Routine screening of donated blood for HCV is highly recommended.
