Introdution: Ischemic mitral regurgitation (IMR) remains one of the most complex and unresolved aspects of ischemic heart disease that the impact of percutaneous coronary intervention (PCI) on improvement of intensity of ischemic mitral regurgitation is not well clarified. Patients with coronary artery diseases and ischemic mitral regurgitation have a worse prognosis than the patients with coronary artery disease (CAD) and those without ischemic mitral regurgitation. We sought to investigate the impact of complete revascularization by percutaneous coronary intervention PCI on improvement of IMR in patients with CAD and comparisons of echocardiography indices in patients with and without improvement of ischemic mitral regurgitation. Methods: In this cross sectional retrospective study, echocardiographic reports in pre-percutaneous coronary intervention time and 12 months after PCI of patients with moderate (≥ 2+) ischemic mitral regurgitation who underwent complete revascularization by percutaneous coronary intervention from Farvardin 1391 to Esfand 1393 were included in the study. Then, echocardiographic data of the patients with improved ischemic mitral regurgitation compared with the patients with non-improved ischemic mitral regurgitation. Results: Comparison of echocardiographic indices before and after percutaneous coronary intervention revealed that after percutaneous coronary intervention (P = 0. 002) in 15 patients (16%), improvement in ischemic mitral regurgitation was occurred. Also, left ventricular ejection fraction (P = 0. 010), left ventricular end-diastolic (P = 0. 003) and end-systolic diameters (P < 0. 001), wall motion score index (P = 0. 003), left atrial area (P = 0. 001) and systolic pulmonary artery pressure (P = 0. 046) in pre-percutaneous coronary intervention echocardiography were different between improved and none-improved IMR group. Conclusion: Although, percutaneous coronary intervention can lead to improvement of ischemic mitral regurgitation but most patients did not show improvement of ischemic mitral regurgitation after percutaneous coronary intervention. The structural abnormality of left ventricle and atrium were different between improved and none-improved IMR group.

Background: Hyperreactio Luteinalis (HL) is a rare condition during spontaneous pregnancy characterized by bilaterally, or in rare cases, unilaterally enlarged ovaries containing multiple self-limited theca lutein cysts, usually associated with high maternal serum levels of human chorionic gonadotropin (HCG) and hyperandrogenic state. Most of the patients require surgical intervention during their pregnancy because of ovarian torsion, preeclampsia, syndrome of hemolysis, elevated liver enzyme levels, and low platelet levels (HELLP), or to rule out ovarian malignancy. However, we can avoid unnecessary surgical intervention with accurate diagnosis of HL by means of laboratory tests and magnetic resonance imaging (MRI).Case Report: A 27-year-old pregnant woman with gestational age of 27 weeks was admitted with labor pain and complicated with HELLP syndrome. In ultrasonography, bilateral and multiple ovarian cysts were seen.Conclusion: Reviewing this case suggests a relationship between HL and HELLP syndrome and may help to explain the underlying causes of preeclampsia; HL may be a predictor of preeclampsia and HELLP syndrome in pregnancy.

Background: Despite recent improvement in coronary intervention, there are many controversies about its results in diabetic patients. The goal of this study is comparison of in hospital outcome of diabetics after coronary intervention with nondiabetics.Methods: In this study 115 diabetic and 115non diabetic patients who admitted for coronary intervention in our center during 1383&84 were entered in an analytic study of Cohort type. Datas about clinical, aniographic, procedural and post procedural (24hours) characteristics were entered in each patient’s form. Independent T test,chi-square and Fisher’s exact test were used for analyzing datas.Results: The Diabetic Patients were most often older men, and they had higher angina class, more co-risk factors and lower ejection fractions. Diabetic’s lesions were longer and more located in proximal portion of vessels. But success rate, major complication (death, revascularization, Q Wave MI and CVA), and minor complications (coronary/peripheral arteries complication, pulmonary edema, ischemic ECG) had no significant differences between two groups.Conclusion: Diabetes mellitus does not affect short outcomes of coronary intervention as an independent factor. So intervention could be done in these patients with considering favorable outcomes.

Background: Measures to protect the public following an accidental release of radionuclides to the environment will depend on the circumstances including the extent of the potential hazards. The projected levels of risk are an important precondition in emergency planning. The levels can be expressed in terms of concentration levels in the environment or in foodstuffs. These derived intervention levels (DILs) can be determined for the range of important radionuclides that could be released to the environment in the event of a nuclear accident. Materials and Methods: Derived intervention levels for 90Sr, 131I, 134Cs + 137Cs, 238Pu + 239Pu + 241Am and 103Ru + 106Ru radionuclide groups were calculated for infants (<1 year) and adults (>17 years) for mostly consumed foodstuffs in Iran. Calculations of DILs were based on recommendations from international, national organizations and average food consumption rate data for Iran. Results: From our research it was found that DILs for foodstuffs consumed in Iran for above mentioned radionuclide groups except for Ruthenium group are equal to 387, 250, 1023 and 2.8 Bqkg-1 respectively. Conclusion: The comparison of DILs for foodstuffs consumed in Iran and DILs adopted in the new food and drug administration (FDA) Compliance Policy Guide (CPG) which are 160, 170, 1200, 2 Bq.kg-1 for 90Sr, 131I, 134/137Cs, 238/239Pu plus 241Am radionuclide groups respectively, shows agreement with cesium and plutonium group and higher values for strontium and Iodine group. In the case of nuclear accident or radiological events that might affect our country calculated DILs can be used to prevent or reduce exposure due to consumption of foodstuffs.

Knowing how to think about the language learning process is conducive to effective learning especially in the case of grammar structures. Metacognition, a concept derived from cognitive psychology, can assist learners in this case. With regard to young adolescents at lower proficiency levels, there is a long-standing debate on whether to use L1 for teaching metacognitive strategies since learners might not be efficient enough in terms of understanding the concept of metacognition. Therefore, this smallscale experimental study focused on the effect of grammar instruction through the metacognitive intervention delivered in L1 on the EFL pre-intermediate learners' grammatical performance in English and investigated their attitudes towards grammar instruction delivered in L1. To fulfill these purposes, a homogenous group of 20 language learners was randomly divided into an experimental group (n =10), which received grammar instruction through the metacognitive intervention delivered in L1, and a control group (n =10), which received the instruction only in English without grammar instruction through the metacognitive intervention delivered in L1. The results of the independent samples t-test indicated that the experimental group did not outperform the control group in terms of all four English grammar points, namely present perfect, simple past tense, comparative and superlative adjectives, and past progressive. In addition, the findings obtained from the fivepoint Likert scale questionnaire which was distributed among the learners suggested that they had positive attitudes towards the use of L1 (Persian) in teaching English grammar. We argue that low working memory capacity, overreliance on translation, and lesscognitively activated L2 processes may account for the low performance of the experimental group learners in the grammar tests. The implication is that the L1 use in an L2 classroom can be helpful in teaching L2 grammar through the metacognitive intervention, but future studies need to examine how and to what extent L1 should be used to yield more effective results in the case of lower-proficiency learners in an EFL context.

Background and Aims Chronic kidney disease is a progressive disease with poor prognosis. Chronic illness and prolonged need for dialysis may lead to mental disorders such as anxiety. The current study aimed to assess the effect of breathing anxiety level of patients undergoing dialysis. Methods This study was a clinical trial. A total of 100 patients undergoing hemodialysis were selected by convenience sampling method. Then the samples were randomly assigned to experimental and control group. The experimental group received breathing intervention for eight sessions in a month under the guidance of a nurse and the control group received routine care. The research instrument was a tow-part questionnaire of demographic data and Spielberger’ s State-Trait Anxiety questionnaire. Data were analyzed by descriptive statistics (frequency, percentage, mean and standard deviation), and inferential statistics (independent t test, repeated measures and Chi-square). We used SPSS version 18 and P<0. 05 was considered as significant level. Results The mean scores of the situational anxiety before and after the intervention in the control and experimental group showed a significant difference. This difference in the control group was lower at all times compared to the experimental group (P≤ 0. 000). Conclusion Breathing intervention was effective in reducing situational anxiety in patients undergoing hemodialysis.

The aim of this study was to investigate the effect of using portulaca oleracea as a source of plant antioxidants for feeding fattening male lambs, on carcass traits, meat quality, and oxidative stability. Twenty-one male lambs with an average weight of 24±1.5 kg and 150±15 days old were fed with one of the experimental rations included a diet without portulaca oleracea as control, a diet containing 7.5%, and a diet containing 15% portulaca oleracea, for 84 days. The muscle (Longissimus dorsi) samplewas used to determine pH, chemical composition, colorimetric properties, and oxidative stability of meat. Meat lipid oxidation was determined after 1, 7, and 30 days of refrigerated storage using thiobarbituric acid (TBARS). The use of portulaca oleracea in diets improved meat color characteristics such as L, chroma, and Hue. The highest ash concentration and the lowest meat moisture were observed in the treatment of 15% portulaca oleracea (P<0.05). Meat pH was the lowest in the first hour after slaughter but did not differ at 24 h. Compared to the control, in both treatment groups feeding the lambs with portulaca significantly reduced the concentration of Malondialdehyde in the meat of the lambs and increased the meat oxidative stability (P<0.05). The results of this experiment showed that feeding portulaca oleracea by improving properties such as color and increasing the meat oxidative stability improves meat quality, which may have lead to an increase in its nutritional value in terms of human health.
