Page 1High blood pressure (BP) is considered as a strong predisposing factor for cardiovascular diseases (CVD) Environmental and genetic factors may have a role in high blood pressures. Nutrition has a potential role in the prevention of hypertension and its sequelae. Effect of lowering blood pressure by modification of complex dietary patterns may be the result of synergism between the various components of certain foods or food combinations rather than of the specific effect of a particular nutrient. Vegetarian Diet, Mediterranean Diet, and Dash Diet are three food patterns which have been associated with lowering BP. Vegetarian Diet are characterized by high intake of legumes, nuts, vegetables, and fruits. A relatively high polyunsaturated to saturated fat ratio will make by this kind of diet. Low fat content and high potassium, magnesium, and fiber content of this diet, all factors possibly cooperating to the reduction of blood pressure. Mediterranean Diet has low animal and dairy products as well as saturated fatty acids and cholesterol; it is rich in plant food, legumes, fiber, and antioxidant vitamins with olive oil as the main source of fat. The dietary approaches to stop hypertension (DASH) is a success process in control of hypertension, which emphasizes vegetables and fruits and dairy foods with low-fat, it also includes more nuts, poultry, fish, and, whole grains and lower amounts of red meat, fats, sweets, and sugar-containing beverages. DASH diet is poorer in total and saturated fat and cholesterol and richer in potassium, magnesium, calcium, and fiber in comparison to the habitual Western diet. In conclusion, although multiple dietary factors can influence on BP and each factor has a modest effect; the combined effects of those factors can be substantial. In the current study, we review food patterns, lifestyle, and their relationship with hypertension and the possible mechanisms involved.Keywords: Food Patterns, Lifestyle, Hypertension

Page 3BackgroundHuman leukemia inhibitory factor (hLIF) is a poly functional cytokine with numerous regulatory effects on different cells. Main application of hLIF is maintaining pluripotency of embryonic stem cells. hLIF indicated effective work in implantation rate of fertilized eggs and multiple sclerosis (MS) treatment. Low production of hLIF in eukaryotic cells and prokaryotic hosts problems for human protein production convinced us to develop a simple way to reach high amount of this widely used clinical and research factor.ObjectivesIn this study we want to purify recombinant human leukemia inhibitory factor in single simple method.Materials And MethodsThis is an experimental study, gene expression: human LIF gene was codon optimized for expression in Escherichia coli and attached his-tag tail to make it extractable. After construction and transformation of vector to E. coli, isopropyl β-D-1-thiogalactopyranoside (IPTG) used for induction. Single step immobilized metal affinity chromatography (IMAC) used for purification confirmed by Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and western blotting. Bioactivity of the hLIF were tested by MTT assay with TF-1 cells and CISH gene stimulation in monocyte and TF-1 by real-time PCR. Induction by 0.4 mM of IPTG in 25°C for 3 hours indicated best result for soluble expression. SPSS indicated P 0.05 that is significant for our work.ResultsCloning, expression, and extraction of bio active rhLIF was successfully achieved according MTT assay and real time PCR after treatment of TF-1 and monocyte cell lines.ConclusionsWe developed an effective single step purification method to produce bioactive recombinant hLIF in E. coli. For the first time we used CISH gene stimulating for bioactivity test for qualifying of recombinant hLIF for application.Keywords: Recombinant Leukemia Inhibitory Factor, Codon Optimization, Bioactivity Assay, Escherichia coli

Page 4BackgroundAlzheimers disease is one form of dementia in old age. Alzheimers disease is among the incurable diseases which usually show its symptoms in the seventh decade of human life. The disease may be present in the body for years without the incidence of the symptoms. Considering many research studies on this disease, the cause of Alzheimers disease is still unknown. Alzheimers disease occurs hereditary or accidentally in old people.ObjectivesBased on the importance of Alzheimers disease and lack of a cure (definitive treatment) for this disease, we decided to use Data mining method to identify the hidden patterns in effective genes causing the incidence of this disease.Materials And MethodsIn this analytical study, we identified the genes with altered expressions in patients diagnosed with Alzheimers disease. In this research, we identified genes with an increase and decrease in gene expression in patients diagnosed with Alzheimers disease and then presented the important sequences found in each gene of this disease as Alzheimers biomarkers. Microarray libraries related to Alzheimers disease were used and finally, we weighted the data using 10 data mining methods.ResultsThe sequences gain a weight more than 0.5 in at least two of the weighting algorithms, would be chosen as the most important sequenses.our work shows that TGCCCC; AGCCTG; GAATAT, AATTG; And AAATTG are the most important sequences since these sequences have been chosen as the most important sequences in 8 repetition of weithening algorithmsConclusionsThe results of this thesis are consistent with the results obtained from the previous researches and confirm the previous assumptions. The important effect of beta amyloid and E- T PAZ and Kinase and microglobulin genes in Alzheimers disease is validated in the previous researches too.Keywords: Alzheimer's Disease, Genes, Data Mining, Biomarkers

Page 7BackgroundThe freezing of immature testis tissue and then the transplant of it can be considered as a major step in fertility preservation for young boys with cancer.ObjectivesThe objective of this study was to investigate antioxidant effects of vitamins E and C on testis tissue structure in the two types of freezing-thawing (fast and slow).Materials And MethodsIn this experimental study, 16 immature male mice (6 to 8 day-old) surgery, and testes were removed. The testes were divided randomly into 4 groups: control group and three experimental groups including: vitamin E, vitamins C and vitamins E and C. Testes placed in 4 prepared freezing solutions. These solutions, which were: 0.1 mM solution of vitamin E, 1 mM solution of vitamin C, solution of the vitamins E and C with mentioned doses and control solution, were prepared in the DMEM (Dulbeccos modified eagle medium) base culture. Of each group were 4 testes into fast freezing-thawing procedure and 4 testes were into slow freezing-thawing procedure. Finally these testes, for analyzing injury, were stained with hematoxylin-eosin.ResultsIn the fast freezing-thawing procedure, seminiferous tubules injury significantly reduced in any of the three experimental groups compared to the control group (P = 0.01). At the slow freezing-thawing procedure, seminiferous tubules injury any of the three experimental groups significantly reduced compared to the control group (P = 0.01). In both procedures, there was no significant difference between the three experimental groups.ConclusionsIt seems that vitamins E and C due to its antioxidant properties protects seminiferous tubules from oxidative injury.Keywords: Vitamin E Vitamin C_Testis_Immature Mice

Page 8BackgroundIn surgical treatment of thoracolumbar burst fractures, most authors try to lower the number of vertebrae involved during the surgery.ObjectivesThe aim of this study was to evaluate the outcome of a medium-segment posterior spinal fixation in these patients.
Patients andMethodsWe retrospectively reviewed 27 patients (18 male, 9 female) with mean age of 39.4 ± 15.0 years old in a before-and-after study. The mean follow-up period was 38.4 ± 15.6 months. We involved 2 intact above vertebrae and one intact below vertebra, inserting a pedicular screw at the fractured level and supplemented the construct with contralateral infralaminar hook. Clinical and radiologic characteristics were assessed with American spinal injury association (ASIA) scale, oswestry disability index (ODI), visual analogue scale (VAS), and plain radiography. Data analysis was carried out by SPSS version 11.5 software.ResultsMean post traumatic kyphosis was 15.7° ± 3.3° that was changed to - 8.5° ± 4.3° and ° ± 4.4° at immediate and last visit after surgery, respectively. Mean loss of correction (LOC) was 9.5° ± 1.9° (PConclusionsIn surgical treatment of thoracolumbar burst fractures, a medium-segment posterior spinal fixation, although cannot maintain the radiologic reduction of the fractured vertebrae efficiently, is not only associated with acceptable clinical outcome but also spare one lower intact lumbar segment and therefore recommended.Keywords: Spinal Fractures Instrumentation, Pedicle Screws, Spinal Fusion -
