Abstract: The objective of this study was to investigate whether there was a significant difference between the impact of narrative task and personal task on EFL learners’ speaking. For this purpose 60 intermediate EFL learners were selected from a sample of 100 students based on their performance on a piloted PET and randomly assigned to two experimental groups of 30 participants each. The homogeneity of the participants of the two groups in terms of their speaking was also checked by means of an independent samples t-test run on their speaking mean scores. After the treatment, the participants took another PET speaking and the results were analyzed by means of an independent samples t-test. The statistical analysis revealed no significant difference between the effect of narrative task and personal task on EFL learners’ speaking. Therefore the researcher was unable to reject the null hypothesis and concluded that the two tasks bore equal impact on the speaking of the participants.

Abstract: Taxonomic diversity of understorey vegetation (herb species) was studied in two evergreen forests, viz. oak and pine in the Kumaun Himalaya. In terms of taxonomic diversity, Asteraceae and Lamiaceae were the two dominant families in the sampling forest types. Maximum number of species was found at hill base and minimum at hill top in both the forests. The number of families, genera and species ratio observed for pine forest was of course higher with compared to the oak forest showed about the higher taxonomic diversity. Perennials form had higher contribution as compared to annuals forms indicated better ability to store up soil. Very few species (9 species) were found to be common indicates higher dissimilarity in both type of forests. Species richness (per m2) was higher in the pine forest than the oak forest. A high value of beta-diversity in the oak forest point out that the species composition varied from one stand to another. However, low concentration of dominance value in the pine forest with compare to the oak forest point towards the dominance, which is shared by many species.

Abstract: Introduction: Using mouthwashes have been recommended for prevention and control of caries and periodontal diseases due to their affection on restorative dental materials. So, the purpose of this in vitro study was to investigate the effect of three mouthwashes of Chlorhexidine, Oral-B and Irsha on micro leakage of a composite resin. Methods: 56 class 5 cavities were prepared on buccal and lingual surfaces of 28 human molars. The cavity margins were placed 1mm occlusal and apical to CEJ, respectively. After restoring teeth with composite resin, they were randomly divided into four groups and immersed in solutions for 12 hours, then submitted to thermocycling. The specimens were coated with nail varnish, and then immersed in 2% basic fuchsin for 24 hours. Teeth were mounted in epoxy resin and sectioned buccolingually. Leakage scores were evaluated based on a standard ranking, under microscope (25x). Data were analyzed with Kruskal - wallis and Mann-Whitney tests at P<0.05. Results: degree of micro leakage between occlusal surfaces (P= 0.777) and between Gingival surfaces (P= 0.232) in four experimental solutions, was not significant. Also, Degree of micro leakage between occlusal and gingival of each group was not significant (P>0.05). Conclusion: The results of this study revealed that use of mouthwashes didn’t increase micro leakage.

Abstract: Seven local samples of Roselle (Hibiscus sabdariffa L.) collected from different locations from Egypt (Siwa, Cairo and Aswan). Molecular genetic analysis elucidated the genetic distances among them. Polymerase Chain Reactions based on Randomly Amplified Polymorphic DNA (RAPD-PCR) and Inter Simple Sequence Repeats (ISSR-PCR) analysis performed to establish molecular markers as a fingerprint for these seven samples. Eleven 10-mer arbitrary RAPD primers out of total twenty seven and eight ISSR primers had successfully generated reproducible polymorphic products. RAPD and ISSR profiles were pooled together to elucidate the genetic relationships among the examined seven Hibiscus samples. The constructed dendrogram tree divided the studied samples into two main genetic clusters. First cluster includes the sample Light Red LR (Siwa). Second cluster comprises six samples [Dark Red DR1 (Siwa), DR2 (Siwa), DR (Cairo), DR (Cairo), White W (Cairo) and DR (Aswan)].

Abstract: In most parts of the low grade metamorphic rocks or complex is called "Gorgan's Schists" by Gansser, 1951. Much Fungal spores and fruit body could be found in this rock unit. This kind of palynomorphs can be obtained from low grade sedimentary metamorphic rocks such as Slate, Phylite, Calcphylite and Calcschist. Along with the processing of 250 samples the author have encountered with Fungal fruit body that are accompany by fungal spores, Angiosperms pollen, Gymnosperms pollen, and Pteridophytes. All the mentioned palynomorphs are close resemble with Tertiary Palynomorphs which are reported from rest of the world. In this investigation the author have obtained Fungal fruit body less than the other kinds of Tertiary Palynomorphs that are presented in this paper. According to frequency of Tertiary Palynomorphs in G-organ's low grade metamorphic rocks can ascribe most parts of this complex to Tertiary geological time. Previous studies have assigned this rock unit to Precamberian, upper Devonian, upper Paleozoic and Preliassic. A few reworked palynomorphs have obtained by sample processing that help the complex and mixing event such as Olistostorome theory. Because of mixing and metamorphism cannot indentify a boizone in this rock unit.

Abstract: Diabetes mellitus is a chronic disease which the body cannot synthesis insulin or use insulin properly. Prangos ferulacea is a potential source of natural antioxidants. The aim of the present study was to evaluate the effect of the hydroalcoholic extracts of Prangos ferulacea on blood glucose and serum lipids serum in diabetes induced by streptozotocin in Wistar rats. Forty eight rats (150-250g) were divided to six groups randomly. Three groups out of six were administered with intraperitoneal injection of streptozotocin to become diabetic. Group I received distilled water. Group II and III of animals received 300, 500 mg/kg/day Prangos ferulacea extract. Group IV received distilled water (diabetic control) and animals of groups V and VI were treated with Prangos ferulacea extract 300 and 500 mg/kg body weight respectively. The animals were given the extract orally by an intragastric tube once daily for three weeks. The triglyceride, total cholesterol, LDL and HDL were measured in all groups. The Blood glucose and body weight was recorded weekly for each group. Results were analyzed statistically using an analysis of variance (ANOVA). Treatment with Prangos ferulacea extract showed a significant decrease in blood glucose, total cholesterol and LDL and no significant in triglyceride and HDL levels. Also the body weight significantly increased in Group of VI compared to diabetic control group. The findings of this study indicate that the administration of Prangos ferulacea improved lipid profile and blood sugar level in diabetic rats.

Abstract: There are controversies regarding sodium valproate efficacy in schizophrenia. Although some studies have reported that it is effective in the treatment of positive symptoms and aggression in schizophrenia, others have not found such an association. Our study aims to investigate the effects of as an adjunctive valproate in the pharmacological treatment of patients with schizophrenia. Methods: In a clinical trial, 22 schizophrenic patients (age 18 – 65), were randomly allocated into two groups. The first group was treated by combination of valproate and trifluoperazine and the other by trifluoperazine alone. A diagnosis of schizophrenia was established based on DSM-IV-TR criteria. The collected data on the 1st, 14th and 28th days of the admission by PANSS test and were analyzed by Paired T tests through SPSS. Results: Comparison of PANSS mean score in two groups, before and after the trial, showed statistically differences. There was a statistically significant reduction in positive symptoms in the group treated with valproate plus trifluoperazine than trifluoperazine alone after 2 weeks of treatment; the difference was also significant in the fourth week. Conclusion: Our study shows that valproate can do as an adjunct to antipsychotic drug in the treatment of positive symptom of schizophrenia.

Abstract: Ebne-Sina, among other Islamic philosophers, is the person who works more about problem of ultimacy and aim of Divine acts. He, according to satiety of existence and self existent, has been denied of extra aim over essence from his holy essence, there, aim is the same of essence.He loves himself per se, and consequently is lover of his creatures and effects. Extra aim ove essence is for things that are incomplete, things which are complete in possible perfections, are superemperical of having extra aim over the essence.

Abstract: Memantine, a drug approved by the FDA for the treatment of moderate to severe Alzheimer's disease, acts as a weak nonselective NMDA receptor antagonist. This study aimed at evaluating the efficacy of complementary use of memantine in treatment of schizophrenia with chronic course. This clinical trial study was conducted on 60 patients with chronic schizophrenia Diagnosis was established using DSM-IV criteria. The antipsychotic medication dose was kept constant for at least six weeks before entry and throughout the entire study period. Memantine was started on day one at a single morning dose of 5 mg, as add-on to antipsychotic drugs. Dose was titrated weekly by 5 mg, up to 20 mg dose at eighths week. Clinical assessments were performed monthly, using the Positive and Negative Syndrome Scale (PANSS). Participants comprised of chronic schizophrenia. Mean age of the study patients was 44.15 9. 65 years. Memantine and adding it to the consumption of other antipsychotic drugs had not any significant effect on Positive and Negative scale. In the total score of PANASS in three levels of evaluation, there was no significant different between two groups which represent that adding memantine to risperidone had not any significant effect on Positive and Negative scale, combination one and general pathology. Memantine add-on to risperidone therapy was not associated with improvement in negative and positive symptoms in refractory schizophrenia patients.

Abstract: Staphylococcus aureus has long been recognized as an important pathogen in human disease. Diabetes introduced as one of the risk factors in increasing the probability of staphylococcus aureus colonization in nasal anterior cavities. This study aimed at comparing the polymerase chain reaction (PCR) versus anterior nair swab culture for detecting nasal carriage of staphylococcus aureus. In this descriptive-analytical study, samples were taken from nasal mucus of 126 diabetic patients using cotton swab and polymerase chain reaction (PCR). A questionnaire consisting of information such as patients’ personal particulars including age, gender, duration of the diseased, how the diabetes is controlled, HbA1C (based on the recent test of the patients which should not belong for more than three months ago) was filled for all patients. Out of all 126 understudy diabetic patients, 26 cases (20.6%) were known as carriers of staphylococcus aureus in nasal mucus. Out of all 126 understudy diabetic patients, 32 cases (25.4%) were known as carriers of staphylococcus aureus with PCR. Mean duration of detected diabetes was 7.966.61 and 7.767.51 years among subjects with positive culture of staphylococcus aureus and nuc, respectively. According to the statistical analysis, there was not any significant relationship in this regard (P=0.42). Mean HbA1C was 7.76% and 8.52% in groups with positive culture of staphylococcus aureus and nuc+, respectively (P=0.045). In diabetic patients, frequency of staphylococcus aureus colonization of nasal mucus in patients with poor control of blood sugar is not significantly different than polymerase chain reaction (PCR).

Abstract: Tuberculous meningitis (TBM) is the most common form of central nervous system tuberculosis (TB) and has very high morbidity and mortality. TBM is typically a subacute disease with symptoms that may persist for weeks before diagnosis. This study evaluated those patients hospitalized with tuberculosis meningitis within the last twenty years in Tabriz, Iran. This descriptive analytical study evaluated all patients hospitalized with tuberculosis meningitis during twenty years. The patients were divided into adults and children groups. The study was conducted on 71 adults and 21 children. Required information including age, gender, main complaint, other symptoms of the disease, duration of the symptoms onset before hospitalization, records of close contact, records of vaccination for children were collected using characterization sheets. Mean age of the patients was 30.12 6.14 years, respectively. Considering physical examination, neck rigidity, Kernig sign, and Brudzinski's sign were respectively the most common ones. The disease was more prevalent in younger-than-4-years old children and young adults. Meningitis, TB meningitis, mal-treated meningitis, and viral meningoencephalitis were regarded as the most common primary detections among adults and TB meningitis, mal-treated meningitis, and bacterial meningitis among children. This study demonstrated descending process of tuberculosis meningitis incidence at infectious disease wards of adults and children (within the last twenty years).

Abstract: Computed tomography angiography (CTA) is increasingly used for non-invasive imaging of the cerebrovascular diseases. This study aimed at evaluating the circle of Willis location and relationship with its variations by multi detector CT angiography. This descriptive analytical study was conducted on 240 healthy participants who underwent 64-section CTA All participants underwent cranial CTA with a 64-section multidetector CT scanner All component vessels at the circle of Willis were assessed in each individual. In interpretation of the CT angiograms, the observer assessed the presence or absence of each arterial segment in the circle of Willis. A complete circle of Willis was seen in 68 (28.3%) of 240 subjects. An incomplete anterior and posterior circle of Willis was found in 36 (15%) of 240 subjects. The remaining 136 (56.6%) subjects had partially complete circle of Willis configuration. The most common type of circle of Willis in a single subject was anterior variant A and posterior variant E. A higher prevalence of compromised posterior collaterals was observed in this Iranian population compared to western populations.

The main purpose of this study was to assess the usefulness of transperineal sonography as a safe and available method in discrimination between low and high type of imperforate anus. In this descriptive analytical study, 44 neonates with imperforate anus referred to Tabriz Children hospital were evaluated in a 15-months period. The transperineal sonography was performed with a 7-10 MHz linear array transducer and distance between the distal rectal pouch and the perineum was measured. The sonographic findings were compared with surgical ones. Forty four neonates with imperforate anus were evaluated. Based on surgical results, the low and high type of anomaly were confirmed respectively in 24 and 20 cases. The type of anomaly were correctly diagnosed by the use of transperineal sonography in 35 of the 44 patients (80%). In 20 of the 24 patients (83%) with a low type imperforate anus and in 15 of the 20 patients (75%) with a high type imperforate anus sonographic findings were concordant with surgical findings. This study dmonstrated that in neonates with imperforate anus a transperineal sonography is a noninvasive useful method for differentiating low and high types of imperforate anus.

Abstract: Surgical correction of geno varus should be performed as early as possible. Overload osteoarthritis, even without significant varus deformity of the knee, is a further indication for open-wedge high-tibial osteotomy. This study aimed at comparing the genu varum correcting results using classic and modified open wedge high tibial osteotomy. This clinical trial study was conducted on two groups of patients with genu varum deformity. 32 patients with genu varum and candidate to surgery were randomly divided into two equal groups and underwent classic and modified open wedge high tibial osteotomy. These two groups were matched considering age, gender, and BMI. Mean age of the patients was 32.45 8.65 years. 10 cases suffered from bilateral genu varum and 21 patients from one-lateral. There were 6 cases of intra articular fracture in open wedge method. They were fixed using screws during operation. However, there was not found any case of fracture in modified open wedge method. There was not any other postoperative complication (compartment syndrome), DVT vascular complications, knee rigidity, bedsore, and nonunion in modified or open wedge methods. Generally, both surgical methods can be used to correct deformity. Modified open wedge method is preferred to classic open wedge one considering lack of intraarticular fracture in this method since it can threat long-term prognosis of the surgery.

Abstract: The effect of a nuchal cord on the outcome of delivery is controversial. This study aimed at evaluating the fetal blood circulation in nuchal cord of fetus with cephalic or breech presentation by Doppler Sonography. This cross sectional study comprised 100 normal pregnancies, which were studied prospectively. All women were examined by ultrasound at 36 2 weeks’ gestation by the same operator (PG). A real-time ultrasonographic device (Aloka 3500) was used. The presence or absence of a nuchal cord was documented sonographically. Of 100 fetuses with nuchal cord, 78 (78 %) had cephalic presentation and 22 (22%) had breech presentation. The mean age of all women surveyed was 28.5 6.3 years. The difference between the umbilical artery PI index of cases with single and two round nuchal cord was statistically significant (P=0.02), whereas there was no significant difference in the thoracic aorta (P=0.95). The difference between the thoracic aorta and umbilical artery PI of cases with three round nuchal cord was statistically significant (P<0001/0 and P=0.05). The difference between umbilical artery PI with 2 round and 3 round nuchal cord was statistically significant (P+0.02), whereas there was no significant difference in the thoracic aorta (P=0.21). Color Doppler sonography is a sensitive and specific method of diagnosing nuchal cord in fetus with cephalic or breech presentation.

Abstract: Cancer is the most important factor of death after cardiovascular diseases in human populations. So, the reserachers consider cancer as a factor of 13% of deaths that occur in the world. However, breast cancer is the most common type of cancer in women. Statistics show that the number of patients referred to America's Breast Cancer Clinic increased from 3745 in 2003 to 6671 in 2009 and cases of breast cancer diagnosed each year increase from 110 to 529. due to the growing statistics, understanding the maina factor of breast cancer (heredity) is very important which is considered less than other factors directly involved in development of breast cancer. The aim of this paper is to examine the effect of this factor on other factors contributed to breast cancer development.
