Abstract: Learning disability is a life-long condition that can affect academic functioning, everyday life and social life. In multiple areas, academic and other, students with LD often underachieve, and often with pervasive negative consequences. This study compared self-efficacy and hope in 30 elementary school (sixth grade) children with learning disabilities (LD) and 30 their peers without LD. An ex post facto design was used. Statistical population comprised of all students in elementary schools (sixth grade) in, Harsin, Iran, during the 2012-2013 academic year. Students with learning disabilities were randomly selected. The students with LD had been diagnosed by Colorado Learning Difficulties Questionnaire (CLDQ). The students completed the Wechsler Memory Scale, General Self-Efficacy Scale, and Children’s Hope Scale. Data were analyzed using analysis of variance. The Statistical Package for Social Sciences (SPSS 20) was used for computing descriptive statistics and analysis of variance. Differences were found between the groups on the self-efficacy and hope. The study demon-strated the important role of self-efficacy and hope for students with LD.
Pectinase Production in a Defined Medium Using Surface Culture Fermentation
Haidar Abbasi,Mohammad Hassan Fazaelipoor
International Journal of Industrial Chemistry , 2010,
Abstract: Two pectinase producing fungi species were isolated. Using a defined mineral medium and pectin as the carbon source, the capability of the species to produce pecinase was investigated in surface culture fermentation. The results showed that Aspergillus niger performs better than Thericoderma reesei in term of pectinase production, glucose has a repressive effect on pectinase production, and among nitrogen sources of ammonium sulfate, yeast extract , and sodium nitrate, ammonium sulfate is the best. The maximum exo-pectinase obtained in this research was about 1.7U/mL and the maximum endo-pectinase activity was about 0.015U/mL. Pectinase production was very weak when pectin was substituted by sugar beet pulp probably due to inefficient contact between the microorganism and substrate particles in surface culture fermentation. Using sugar beet pulp in solid-state fermentation gave results comparable with those obtained in surface culture fermentation of pectin and in this research was investigated the feasibility of continuous surface culture fermentation for pectinases production. The bioreactor was placed in an incubator at 35oC.

International Journal of Occupational Hygiene , 2009,
Abstract: The aim of the present study was to assess the industrial noise pollution and its effects on the blood pressure of workers during activities in textile factory in Ilam,which is situated in west of Iran. A cross-sectional study was performed on a group included 81 workers and 30 people as sample and control group, respectively. A questionnaire was filled out and then the other measurements including the total sound pressure level, weight, height, pulse, blood pressure and all the rest of medical examinations have been respectively done. The average sound pressure level measured for sample and control group was respectively (94.86 ±6.63) and (61.93 ± 4.56) dBA. The result also showed that by taking mean values for each quantitative variable, statistically only the age has significant difference between opposing groups. Sound frequency analysis in A and C networks over a frequency range between 125 to 16000 Hz revealed a significant differences in such away that sound pressure level for the sample group was higher than the limited threshold (85 dBA). Moreover, the results from the survey of the total sound pressure level in A –and C – weighted according to blood pressure status, BMI and age indicate a significant statistical correlation between the mentioned variables. A highly significant correlation was found by test between the level of sound pressure, blood pressure status, BMI and the age group in different octave band center frequencies. It is concluded that planning for working hours of workers to decrease the noise exposure and employment of young workers with appropriate BMI may reduce the adverse effects of noise.

Abstract: Background and Aim: Changes in political, economic, social, scientific and technological circumstances have a major impact on organizational performance. In such circumstances, the success of organizations depends on their ability to cope and adapt to changing environmental factors. This study investigated the relationship between organizational participation(team orientation, capability development and empowerment) and the organizational adaptability (change, customer orientation and organizational learning) in Imam Khomeini Hospital staff. Materials and Methods: This cross-sectional study was performed on 114 staffs of Imam Khomeini hospital, Tehran University of Medical Sciences who were selected by random sampling. Data were collected by Denison questionnaire (2006 version), which was confirmed validity and reliability. Data were analyzed with spss17 and statistical methods like the mean, standard deviation and correlation coefficients. Results: The results showed that the rate of the organizational involvement and adaptability of the staffs was 53.44% and 52.37% respectively. The Pearson correlation analysis showed a positive correlation coefficient (p<0.01, r=0.743) between two variables of organizational involvement and adaptability. Conclusion: With increasing organizational involvement of the staffs increases their organizational adaptability

Iranian Journal of Pharmaceutical Research , 2006,
Abstract: Concomitant use of several drugs by ICU( Intensive Care Unit) patients is often unavoidable. In these patients, pharmacokinetic drug interactions are very likely. The current study was designed to evaluate these interactions in patients hospitalized in an ICU of a teaching hospital in Tehran, Iran.A questionnaire was designed and used to collect study data. The study was done in the ICU of a teaching hospital affiliated to the Shaheed Beheshti Medical University. Overall information extracted from 567 ICU prescriptions from March 2005 to December 2005. The extent of occurrence and frequency of potential pharmacokinetic interactions were categorized based on the reference text Drug Interactions Facts. All of the pharmacokinetic drug interactions were extracted and evaluated in terms of mechanism, significance, severity, documentation and onset.There were 413 pharmacokinetic interactions in 567 studied prescriptions, which were divided into 64 types of pharmacokinetic interactions. The most observed interaction was between ciprofloxacin and sucralfate. Mechanisms of the pharmacokinetic interactions were related to metabolism (%60.05), absorption (% 38.26), elimination (%0.97) and distribution (%0.73). There was a direct relationship between the number of drugs per prescription and the frequency of pharmacokinetic interactions (p<0.001, r =0.98) Findings obtained in this study revealed that there is a significant number of rapid occurring, moderate, probable and definite interactions among the ICU prescriptions. This highlights the necessity for the presence of a drug specialist (i.e. clinical pharmacist) to rationalize the therapy and minimize major interactions.

Pakistan Journal of Biological Sciences , 2007,
Abstract: There are two types of alfalfa landraces in Iran. The first is temperate landraces such as Hamedani, Gharah Younjeh and the second is sub-tropical landraces such as Bami, Nikshahri and Yazdi. Do they have different gene pools and could they be identified using agro-morphological traits. A total of 332 landraces which had been collected from different parts of Iran were planted in the experimental field. During 1998-2002, agro-morphological traits were evaluated according to IPGRI descriptors. One way ANOVA analysis showed that the variance among accessions within provinces is not significant for mostly of traits, whereas it was significant among provinces. Cluster analysis revealed that there are five clusters which are grouped in two main clusters. The first main cluster consisted of landraces of central to Northern provinces. The other main cluster consisted of landraces of central to Southern provinces. The results of t-test among quantitative traits in two main clusters and distribution of collected accessions of each province in the produced plot based on two first factor of factor analysis, confirmed the cluster analysis results. Therefore these results revealed that those accessions which were collected from Northern parts of the country were genetically different from Southern accessions. As a result, there are two types of gene pools for alfalfa landraces in Iran. Also this study showed that using agro-morphological traits could be used for distinguishing between two types of gene pools of alfalfa landraces in Iran.

Abstract: Background: Varicocelectomy is considered as standard treatment for male infertility for clinicalvaricocele. The aim of this study is to address the effects of varicocelectomy on semen parameters,chromatin packaging, and pregnancy outcome.Materials and Methods: This retrospective study was carried out between June 2006 and February2011 on 145 infertile men with grade II or III varicocele. Microsurgical varicocelectomy wasperformed as part of patient management. Sperm count, motility, morphology, and chromatinpackaging were assessed with a Makler counting chamber, light microscopy, Papanicoulaou andchromomycin A3 (CMA3) staining, respectively. In addition, we assessed spontaneous clinicalpregnancy and miscarriage rates.Results: The percentages of spontaneous cumulative pregnancies post-surgery were 33.1% (3months), 42.06% (6 months), 46.2% (9 months), 48.9% (12 months), and 55.8% (after 12 months).Percentages of spontaneous cumulative miscarriage post-surgery were 2.46% (3 months), 4.93%(6 months), 4.93% (9 months), 6.17% (12 months), and 6.17 % (after 12 months). Both spermparameters improved and the percentage of sperm protamine deficiency decreased significantlyafter varicocelectomy.Conclusion: These results confirm that varicocelectomy improves sperm parameters and chromatinpackaging, thereby improving the chance of pregnancy. Positive aspects of this study include thelarge number of patients studied, duration of follow up, one surgeon who performed all of thesurgeries, and type of surgery (microsurgery). The spontaneous pregnancy results also suggest thatif pregnancy is not achieved within twelve months post-surgery, an alternative approach such asassisted reproductive technology (ART) treatment should be considered.

Notulae Scientia Biologicae , 2011,
Abstract: Medicinal plants are the most important source of medicine. Cuminum setifolium ( Boiss.) Kos.-Pol. with common name of white cumin, a member of the Apiaceae family, growing wild on mountains was investigated as a species having capability for cultivation and crop breeding. Generally, there is not information about Cuminum setifolium species. The aim of this study was to found plant identification and distribution in Iran, phenology, best treatment for seeds germination, farm cultivation and anatomical description. Cuminum setifolium plant is a annual herb which is distributed in Iran, Turkmenistan, Afghanistan, Pakistan, Tien-Shan and central Asia. In our studied region, the plant is generally grown on calcareous marl soils with climatic conditions of desert cold, semi-arid to arid having hot summer and cold winter. The effects of different treatment on seed germination showed significant highest germination percentage (54.4%), germination rate (6.4%) were obtained from seeds that had exposed for 3 weeks at 4°C after omit of seeds hairs. The experiment of cultivation showed the best time for sowing in Mashhad was autumn and growing time was from middle of March until end of June and ripening seeds were end of June at 2005. Microscopic observation of the root structure showed lacking secondary structures and having epidermis tissue with only a row of cells along with relatively thick cuticle and for stem and leaf structure with stomata without any hairs. Parenchyma cells contained 2-3 rows of irregular oblong cells. Stomata type of epidermis was diacytic and distance between stomata was measured 5 μm in average.

Journal of Medical Sciences , 2006,
Abstract: As the Golestan province has been known as a high prevalent region for TB in Iran; present study was conducted to evaluate TB status in the province. Samples of sputum were obtained from 1205 pulmonary patients. All isolates initially confirmed by ziehl-neelsen`s staining. The collected data were analyzed by SPSS analytical software. A total of 1205 cases of pulmonary TB patients were identified during the study period. 642(53%) were males and 563(47%) females. Eighty present (80%) of cases had fever. Sputum had been shown to be in 79.6% of cases that in 20% of them it was bloody. Ninety-three present (93%) of cases had a history of coughing for more than 3 weeks. Twenty-five present (25%) had a history of TB in their families. BCG vaccination related scar was seen in forty-five present (45%) of cases. Tuberculosis has a higher incidence rate in the area and is more common in females than in males. Reoccurrence (recurrence) of TB seems to be higher in females than males. So it is essential to health care deputies to consider this group (females) as a high-risk group and to consider each contracted family; because of high family history of TB as a major risk factor. In addition to low occurrence of scar lesion following BCG vaccination, it is also needed to conduct better popular trends on vaccination strategies.
