Introduction: Toxoplasma gondii ( T. gondii ) is distributed worldwide and infects most species. The serious incidence and severe or fatal injury caused by T. gondii infection clearly indicates the necessity for the event of a vaccine. The current study goals were to evaluate serological applications of Toxoplasma gondiirhoptry protein 1 (ROP1) antigen. Materials and methods: We created a polymer vaccine by using the eukaryotic plasmid, pROP1. Purification by one-step metal affinity chromatography allowed recovery of milligram amounts of purified recombinant proteins per liter of culture. The quality of this matter for diagnosing of human infections was provided and tested on 77 serum samples which were obtained during routine diagnostic tests. A panel of 20 serum samples from patients with acute toxoplasmosis was compared to a panel of 35 serum samples from individuals with chronic toxoplasmosis. Results: Results of the study indicated that antibodies detected from patients with acute and chronic infections were 96% and 17%, respectively, by using of pROP1 recombinant antigen. Conclusion: According to the present study an immunoglobulin G antibody against ROP1 antigen is made throughout the acute stage of toxoplasmosis infection, but not in the chronic phase of toxoplasmosis.

Introduction: Helicobacter pylori (H. pylori) infection has remained as a global health problem. Animal studies demonstrated the role of H. pylori oipA gene in the development of gastric cancer. The aim of this study was the cloning and expression of Helicobacter pylori oipA gene in a bicistronic vector harboring mice IL-18 gene. Materials and methods: The target gene encoding oipA was amplified from a codonoptimized clone by PCR, and then double-digested by restriction enzymes. The pIRESIgk/ mIL18/Fc plasmid was simultaneously digested by BstXI/NotI enzymes to elicit the eGFP segment. PCR product of oipA was inserted into pIRES-Igk/mIL18/Fc plasmid using T4 ligase. Transformation into DH5α strain was done. Cloning was confirmed by PCR, enzymatic digestion and sequencing. Expression of the oipA and IL-18 mRNA was assessed by means of TaqMan Real-time PCR. Results: Electrophoresis of PCR product, enzymatic digestion and sequencing showed that the H. pylori oipA gene was successfully cloned into pIRES-Igk/mIL18/Fc to generate mIL- 18-pIRES2-oipA plasmid. The results of Real-time PCR confirmed the successful expression of both oipA and IL-18 in mouse macrophage cell line. Conclusion: Considering the role of oipA in pathogenesis of H. pylori and potent activity of IL-18 as a molecular adjuvant, the results of the present study showed that the expression of codon-optimized oipA gene in bicistronic vector including mouse IL-18 is successful. So, it could be considered as an appropriate genetic vaccine candidate for H. pylori in future investigations.

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thrombin-activated platelets. After the elapsed co-culture time, the levels of caspase-3 and CD95 were evaluated as a sign of cell death and apoptosis. In addition, immortalized cells were evaluated using trypan blue, 7-AAD and WST-1 methods. Results: CD95 and caspase-3 levels were significantly increased in both cell lines compared with the control cells (P<0.05). Beside, considerably lower number of living cells were shown by trypan blue, 7-AAD and WST-1 in the treatment groups compared with the control group (P<0.05). Conclusion: This study demonstrated the role of apoptosis in tumor inhibition and implied the ability of platelets to induce apoptosis in tumor cell lines.

Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi. Materials and methods: We described a simple procedure for purifying human HLA molecules from the cells lysate. As a representative model, HLA-DR was purified from Daudi cell line. The cell membrane was solubilized by a buffer contained NP-40 detergent. Subsequently, the isolation of the membrane antigen was carried out by affinity chromatography method using mouse anti-human HLA-DR monoclonal antibody. The size and the specificity of the purified antigen were determined by Bradford and ELISA methods, respectively. Results: The purified HLA antigen was obtained in approximately 20-30 micrograms in each run of chromatography. Additionally, ELISA method demonstrated the HLA-DR specificity of the purified protein. Conclusion: The results indicated that affinity purification of HLA-DR antigen by means of specific monoclonal antibody is a simple and fast procedure for obtaining the purified antigen.

Introduction: One of the most important problems in student's education is academic failure. Identifying factors that affecting academic achievement and pay attention to these factors is a stride toward success. Students' academic achievement and related factors have priority in education research. This study aimed to determine the relationship between learning study strategies and academic achievement of nursing students in 2013. Materials and methods: This descriptive-analytic study was performed among 85 nursing students of Ilam University of Medical Sciences. By using the learning and study strategies inventory (LASSI), the main three components of study and learning strategies, including items of skill, will and self-regulation were examined. The Pearson correlation was used to measure students' academic achievement correlation with the mentioned above components. Results: The sample consisted of 50.6% female and 49.4% male. The mean grade of nursing students was scored 15.60. Pearson correlation coefficient showed that the three main components of learning strategies and study skills component, respectively skill (P=0.001, r=0.349), self-regulation (P=0.009, r=0.280) and the component of will (P=0.045, r=0.218) with student achievement (mean grade of last term) had a positive and significant relationship. Conclusion: Considering positive and significant correlation between learning and study strategies with academic achievement in nursing students, so, we suggest that students and teachers use these strategies to improve academic achievement and reduce the academic loss of students.

Introduction: Myocardial infarction (MI) is associated with increased oxidative stress and reduced antioxidants. Some studies have shown that exercise training increases the serum level antioxidants. Therefore, this study investigated the effect of rehabilitation training on antioxidant status in patients with myocardial infarction. Materials and methods: In this study, 20 patients with myocardial infarction were selected and randomly assigned to training group (n=10) or control group (n=10). Training program included 3 sessions of concurrent training per week for eight consecutive weeks. To measure the values of malondialdehyde (MDA), protein carbonylation (PC) and total antioxidant capacity (TAC), 10 ml of blood were taken preand post-training in each patient. The t-test was used to analyze the data. P<0.05 was considered significant in all tests. Results: The data showed that 8 weeks of rehabilitation training significantly reduces MDA (2.37±0.59 μM and 3.74±1.34 μM in training and control groups, respectively; P=0.000) and PC (9.15±1.77 nmol/mg protein and 11.48±1.60 nmol/mg protein in training and control groups, respectively; P=0.006) levels and significantly increases TAC (10.09±1.70 U/ml and 8.34±1.56 U/ml in training and control groups, respectively; P=0.031). Conclusion: Since the findings of the present study show a reduction in oxidative stress markers (MDA, PC) and an increase in total antioxidants capacity, it seems that eight weeks of concurrent training may improve the antioxidant capacity in patients after myocardial infarction.

Introduction: Blood derived products have been known as an effective treatment for many years. However, this treatment is not without risk of infections transmission including hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immune-deficiency virus (HIV) in people who received the blood. Nevertheless, due to a high risk of blood born diseases through blood transfusion, screening for these viruses according to the World Health Organization (WHO) is mandatory. The main aim of this research was to assess the prevalence of HBV, HCV and HIV infections among healthy blood donors of Blood Donor Center of Ilam (BDCI). Materials and methods: In this study we used the information from first and repeated blood donors who referred to BDCI within February 2009 to January 2013. Demographic characteristics of donors including marital status, age, gender and blood donation pattern was extracted. Routine donor laboratory screening tests for HBV, HIV and HCV were performed. Results: HBV infection had the highest prevalence (0.14%) while HIV had the lowest ones (0.006%). The highest prevalence was among male blood donors. The prevalence of HBv, HIV and HCV infections were more common among men and first time donors (P < 0.01). The prevalence of HIV and HCV infections were more common among married donors than singe ones (P < 0.01) HBV prevalence in singles was more (P < 0.05) compared to married blood donors. The highest and the lowest subjects with HBV, HCV and HIV infections were in range of 51 to 60 years and 18-35 years old, respectively. Conclusion: It is estimated that the prevalence of HBV, HCV and HIV infections are low in voluntary blood donors than general population which confirmed the effectiveness of education and examination of blood donors. This usually arising from the pre donation screening for risky behaviors, so deleting the high risk people. Since unsafe blood products are not used for blood transfusion, they are not considered as risk for blood safety system, but identification of these blood units is a problem for blood transfusion centers.

However, this treatment is not without risk of infections transmission including hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immune-deficiency virus (HIV) in people who received the blood. Nevertheless, due to a high risk of blood born diseases through blood transfusion, screening for these viruses according to the World Health Organization (WHO) is mandatory. The main aim of this research was to assess the prevalence of HBV, HCV and HIV infections among healthy blood donors of Blood Donor Center of Ilam (BDCI). Materials and methods: In this study we used the information from first and repeated blood donors who referred to BDCI within February 2009 to January 2013. Demographic characteristics of donors including marital status, age, gender and blood donation pattern was extracted. Routine donor laboratory screening tests for HBV, HIV and HCV were performed. Results: HBV infection had the highest prevalence (0.14%) while HIV had the lowest ones (0.006%). The highest prevalence was among male blood donors. The prevalence of HBv, HIV and HCV infections were more common among men and first time donors (P < 0.01). The prevalence of HIV and HCV infections were more common among married donors than singe ones (P < 0.01) HBV prevalence in singles was more (P < 0.05) compared to married blood donors. The highest and the lowest subjects with HBV, HCV and HIV infections were in range of 51 to 60 years and 18-35 years old, respectively. Conclusion: It is estimated that the prevalence of HBV, HCV and HIV infections are low in voluntary blood donors than general population which confirmed the effectiveness of education and examination of blood donors. This usually arising from the pre donation screening for risky behaviors, so deleting the high risk people. Since unsafe blood products are not used for blood transfusion, they are not considered as risk for blood safety system, but identification of these blood units is a problem for blood transfusion centers.","PeriodicalId":15047,"journal":{"name":"Journal of Basic Research in Medical Sciences","volume":"4 1","pages":"4-8"},"PeriodicalIF":0.0,"publicationDate":"2017-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48421847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 28 years’ pregnant woman with 24 weeks’ gestational age referred with petechiae and purpura from previous day without any trauma. She had an occipital headache from last night. Overt petechial and purpuric lesions were seen in the mouth and skin. There was neither hepatosplenomegaly nor lymphadenopathy. She was conscious and oriented. The patient was febrile, anemic and thrombocytopenic with stable vital signs. All liver enzymes were elevated. Coagulation profile was normal. WBCs were normal. RBCs were reduced, and she had polychromatosis. Overt shistocytosis was seen. Platelets were significantly decreased. The first diagnosis was TTP. All necessary laboratory tests were done to rule out the secondary rheumatologic causes of TTP; which all were normal. Coombs tests were negative. ADAMTS 13 Ab was elevated. Fetal ultrasonography was normal. Treatment started with plasmapheresis and corticosteroid. After treatment, platelets count begins elevated, and LDH decreased. The patient discharged with a good general condition and normal lab tests. She continued her pregnancy until term, and born a normal infant without any complication. She did not have a recurrence of TTP until September 2014.
