Z. Izadi, H. Zarei, M. Alizadeh
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45A006
Abstract:

The influence of two grafting techniques on the success of stenting (simultaneous cutting and grafting) and some ensuing growth parameters of stentlings were studied under glasshouse conditions. The Avalanch and Peach Avalanch glasshouse rose varieties were utilized as scion and grafted on R. manetti as rootstock. Two grafting techniques namely, splice and omega grafting methods were practiced and graft combinations were inserted in cocopeat-perlit (1:2) medium under mist system. The number of roots, longest root size, shoots and leaf numbers and successful grafting percentage were evaluated after grafting. In Avalanch/R. manetti and Peach Avalanch/R. manetti combinations, higher percentage of successful grafting was observed in the

M. Eshaghi Gordji,Z. Alizadeh
Abstract and Applied Analysis , 2011, DOI: 10.1155/2011/123656
Abstract: Using fixed point methods, we prove the superstability and generalized Hyers-Ulam stability of ring homomorphisms on non-Archimedean Banach algebras. Moreover, we investigate the superstability of ring homomorphisms in non-Archimedean Banach algebras associated with the Jensen functional equation.
Survey of incidence, age, sex, etiology of acute hemolysis, clinical and laboratory findings on 62 G6PD deficient patients in Bahrami Children Hospital
Alizadeh Taheri P,Noroozi Z
Tehran University Medical Journal , 1999,
Abstract: This is a study on 62 G6PD patients hospitalized in Bahrami hospital between 1993 to 1995. Favea was the oxidant agent causing acute hemolysis in more than 90 percent of patients. Most of acute hemolysis occurred in spring, the season of high consumption of favea. More than 60 percent of patients had moderate to severe hemolysis with Hb less than 7 gr/dL. According to WHO reports, the incidence of G6PD is 7-12% in Iran and it is favism type. It is suggestive to prevent parents of sugh patients of favea consumption, which in turn decreases the rate of acute hemolysis, its complications, complications of transfusion and hospitalization in endemic area of Iran.

Z. Alizadeh Tabari,M. Kadkhodazadeh,M. Khademi
Research Journal of Medical Sciences , 2012, DOI: 10.3923/rjmsci.2011.141.144
Abstract: Dental plaque has been implicated as the primary etiology in periodontal disease. Developmental aberrations in tooth morphology such as enamel pearls may predispose the affected area to plaque accumulation and consequently cause periodontal breakdown. Enamel pearl is defined as an ectopic globule of enamel that is firmly attached to the tooth root. The enamel pearls occurred more commonly on the roots of maxillary 2nd and 3rd molars. The most common type of enamel pearls are consisted of enamel and dentin. The aim of this study was to present a maxillary second molar with enamel pearl, associated with localized severe attachment loss and to report the pearl structural analysis.

Tehran University Medical Journal , 2011,
Abstract: Background: The aim of this study was to evaluate the mid-term outcomes of concurrent total correction of Tetralogy of Fallot (TOF) after pulmonary valve (PV) replacement and its relation to QRS duration and MRI results.Methods: In this study, 51 patients with TOF who had the TOF surgery and PV replacement enrolled the study. Demographic data, MRI results such as, right ventricular end diastolic volume, right ventricular end systolic volume, systolic and diastolic indexes noted. Moreover, QRS duration and the patients' cardiac functional class were evaluated immediately before and 6 months after the surgery.Results: From 51 patients, 27.5% were female and 72.5% were male. The mean age of participants was 23.48 (SD=5.82) years. Functional class changes were statistically different (P<0.001) comparing the status before and after the surgery. The mean QRS duration before surgery was 130.20 (SD=16.89) ms which was in significant contrast with post-surgical states, 122.45 (SD=16.90) ms (P<0.001). Mean QRS duration before and after surgery was statistically lower in asymptomatic patients (P=0.028 and P=0.025, respectively). There was a statistical relationship between pre-surgical systolic and diastolic indexes to post-surgical functional class as asymptomatic patients had lower systolic and diastolic indexes (P=0.005 and P=0.028, respectively).Conclusion: This study demonstrated that QRS duration before and after surgery can be an indicator to evaluate the cardiac function after surgery for Tetralogy of Fallot. Moreover, systolic and diastolic indexes are factors affecting the good prognosis of patients; therefore, PVR surgery needs to be done before the deterioration of systolic and diastolic indexes and cardiomegaly.
Long term effects of a continuous and intermittent aerobic exercise on weight changes and body fat percentage in overweight and obese women

Tehran University Medical Journal , 2013,
Abstract: Background: Obesity and sedentary lifestyle are growing problem. The global community's concern is to find the best strategy to obtain a more efficient process of weight reduction, increase physical activity, and minimize weight regain level. The purpose of this study was to evaluate the long-term effects of a short-term intervention on weight changes.Methods: The present study is a one-year follow-up study of a 12-week intervention during which the 15 individuals in the intermittent group performed 40 minutes exercise in three bouts per day; however, the 15 participants of the continuous group did the same but 40 minutes continuously. The 15 participants in the control group had no exercise prescription. After one year, weight changes, body fat percentage, and BMI were re-evaluated in the groups.Results: After adjusting the baseline weight, patterns of change in the mean weights from the end of the third month to the twelfth month were different across groups (P=0.02). After significant weight loss in the intermittent group, the mean weight in this group increased by 2.32 kilograms during the period, although not statistically significant. No increase was observed in the control group’s mean weight (P=1.00). In the continuous group, the mean weight increased statistically (P=0.048, 3.63 kilograms).Conclusion: It seems that long-term effects of moderate intensity intermittent aerobic exercise in overweight and obese women on weight control are more efficient than those of continuous exercise. However, for a change in lifestyle and prevention of weight regain, longer follow-ups are required.

Abstract: Introduction: Today, breast cancer is one of the most common causes of mortality and morbidty and also the leading health concern of the world. Methods: This research was a descriptive study entitled; Knowledge, attitude and practice regarding prevention of breast cancer in working women of Chaloos city. The sample size of study included 612 women working in governmental centers. The instrument for data collection was a researcher –made questionnaire. For data analysis, central and coefficient index chi square ,t-test ,one way analysis of variation, Kruscal Wallis, Pearson,s correlation coefficient and Fisher test were used. Results: The findings showed that the most of samples were in the 30-39 years age group,(39.7%) with an educational job(83/5%) and without history of breast cancer history in the family.(94/9%) Results also revealed that there was a weak positive relationship between knowledge and attitude (r=0.33) .The findings showed there was a significant statistical relation between knowledge and practice (p<0.05). Also, there was a significant statistical relation between knowledge level and breast self examination (BSE), time interval and also the time of performing BSE (p<0.0001) Similarly, the highest levels of knowledge were present in women with medical education and those with a bachelors or higher degree. The results showed that attitude scores were significantly different in various age, job and educational groups, (p<0.001, p<0.05,p<0.05) respectively Conclusion: The results showed that most of the population under study had a positive attitude but didn’t have good knowledge or practice.

Abstract: Background & Objective: Osteoporosis is a serious public health concern known to have several etiologic factors. This study compared lifestyles among postmenopausal women with normal and abnormal bone marrow densitometries (BMD). Methods & Materials: In this case-control study, 81 postmenopausal women (33 cases with abnormal BMD and 48 control individuals with normal BMD) were selected using simple random sampling from Osteodensitometry center of Shariati hospital in Tehran. The BMD at lumbar spine and femoral neck had been measured with DXA. The Lifestyle was assessed using a questionnaire containing items about taking calcium, vitamin D, hormones, and Alendronat, doing physical activity, consuming tea and cola, and smoking. Reproductive characteristics were also collected via a questionnaire. Data were analyzed using χ2 test and independent sample t-test. Crude and adjusted odds ratios and relevant 95% confidence intervals were calculated through logistic regression, using SPSS v.13. Results: The results showed significant differences between two groups in weight (P>0.001), BMI (P=0.022), number of pregnancies (P=0.002), number of children (P=0.004), duration of lactation (P=0.0002), dietary calcium intake (P≤0.001), and period of calcium supplement intake (P=0.002). The average of acquired scores of lifestyle factors in the case group was significantly lower than the control group (P=0.037). Inappropriate lifestyle had increased risk of the disease (OR=3.36, 95%, CI: 1.10-10.26). Meanwhile in the multivariate analysis, only insufficient intake of calcium was found to be a risk factor (P=0.002) for osteoporosis. Conclusion: In conclusion, the results of this study showed positive effect of calcium intake on bone mineral density.
