A Survey of Social Cognitive Determinants of Physical Activity among Iranian Women Using Path Analysis Method

Introduction: This cross-sectional study was carried out on 400 women selected from urban health centers in Isfahan through stratified sampling. The study was designed to evaluate the social cognitive theoretical model in explaining determinants of physical activity among women using path analysis method.Methods: In a hypothetical framework, the relationship between self-efficacy, outcome expectation, social support and self-regulation and physical activity were assessed using path analysis and indices of fitness. Furthermore, the predictive power of the model was evaluated.Results: Social cognitive theoretical model had a good predictive power for physical activity. Confirmatory factor analysis revealed the suitability of the theoretical model; this model is able to cover 80 % of physical activity variance. Evaluation of social cognitive theoretical model using path analysis showed that self-regulation was the strongest determinant of physical activity. Social support and outcome expectation had very weak effects on physical activity; nonetheless, their effect was enhanced by the presence of self-regulation. Self-efficacy had a weak effect on physical activity, however as an intermediate variable, it reinforced the impact of social support and outcome expectation on physical activity.Conclusions: The use of the present hypothetical model is suggested as an appropriate framework in research related to physical activity among women as well as to strengthening self-regulation skills in designing and implementing programs promoting physical activities

Ethnobotanical and phytochemical aspects of the edible herb Coriandrum sativum L.

Financiado para publicación en acceso aberto: Universidade de Vigo/CISUGCoriandrum sativum (coriander) is an edible herb in the family Apiaceae. The leaves, fruits, and stems of C. sativum have long been used as culinary spice due to their favorable odor. Traditional practitioners used this plant for treating different diseases like blepharitis, scabies, aphthous stomatitis, laryngitis, headache, and palpitation. In modern researches, coriander has demonstrated anxiolytic, anticonvulsant, antimigraine, neuroprotective, analgesic, diuretic, hypoglycemic, hypolipidemic, hypotensive, anticancer, and antioxidant activities. Coriander contains a wide range of bioactive phytochemicals among which phenylpropenes, terpenoids, isocoumarins, phytosterols, and fatty acids are the most important. This review provides information about the botanical and ethnobotanical aspects, chemical profile, therapeutic uses in Islamic traditional medicine (ITM), and recent pharmacological studies of coriander effects. The results have shown that coriander and its monoterpenoid compound, linalool, can be considered as potential drug candidates for treating metabolic syndrome and different inflammatory conditions especially neural and CNS diseases

Development of slope monitoring device using accelerometer

There are many types of instruments that have been used for monitoring the high risk slopes as a precaution to prevent the loss of lives. Unfortunately, there is no such works of installation slope monitoring instrumentation as detectors and preventive actions before the slope failure. Automatic Wireless Accelerometer Monitoring System (AWAM) is a new device of monitoring system using accelerometer, introduced in this research. It is more efficient than conventional techniques and less expensive. The application and operation of this system does not interrupted by physical obstacles, different climate conditions, and the construction works at site. In addition, no contact is required since the accelerometers are installed on the slope. Consequently, geomorphology limitations are not considered as limitations of the system operation. This paper discusses the sensor database system by AWAM and shows the effectiveness of the device to monitor slope failures and act as a warning sign. It was presented in two parts; the first part consisted of the physical modelling calibration test from sensor database system (AWAM device) and from load cell test while the second part discussed on the numerical model simulated by using software (Slope/W and LimitState) and the data from vane shear test. The AWAM device can be used as a monitoring system to detect soil movements. However, accelerometer was able to give AWAM’s readings if the device is moving in tilting modes

Spring 2015;9(2):29-41. AbstractObjectiveDetection of seizure, its etiology, and clinical types is important for guiding therapy. This study was designed to evaluate the etiology and clinical evaluations of neonatal seizures in Kashan, Iran.Materials and MethodsThe data of 100 hospitalized neonates with a complaint of seizures in Kashan City, from January 2006 to January 2011 were evaluated. The pediatric neurologist made the final diagnosis. The gestational age, neonate admission age, type of delivery, and laboratory and radiological investigations were reviewed   from the medical records. The relation of seizure etiology and other variables were compared using the Chi-square test. All the statistical analyses were performed using SPSS (ver 11.5).ResultsA total of 100 neonates were hospitalized with a diagnosis of seizures. The overall incidence rate of seizures was 2.6 per 1,000 live births. A total of 59% of seizures happened in the first three days of life. The etiologies of seizures were hypoxicischemic encephalopathy (HIE) (36%), hyponatremia (12%), hypoglycemia (11%), intracranial hemorrhage (11%), infections (10%), hypocalcemia (8%), metabolic disorders (7%), the structural anomalies (5%), and hypomagnesaemia (4%). In 23% of neonates, no specific etiology was found and 23% had multiple etiologies. In 45% of neonates, the EEG was not recorded. The type of the seizures were focal-clonic (26%), tonic (25%), multifocal clonic (34%), subtle(11%), and myoclonic (4%). The types of the seizure were unrelated to the paraclinical findings.ConclusionNeonatal seizures are common and HIE was the main cause of seizures in this study. The clinical evaluation of neonatal seizures needs improvement
