- چکیده انگلیسی: Introduction: Many studies have shown that social interactions resulting from participation in physical activities lead to an optimal state of self-esteem. The findings of previous research on gender differences regarding this factor, however, have not been consistent. In an attempt to fill this gap, this study is designed to investigate the effect of physical activity and gender on students' self-esteem in Shiraz University. Methods: Random-Comparative method was employed to conduct this research. Population included all undergraduate students of Shiraz University. Participants were selected through random cluster sampling. 332 students filled out a Cooper Smith and Colleague’s Questionnaire and the scores of 218 of them were analyzed. Two-way analysis of variance was administered for the analysis (P≤0.05). Results: The results conveyed that the major impact of gender (P=0.05) and physical activity (P=0.02) on self-esteem were both significant. Active students had higher self-esteem compared to inactive ones (P=0.02) and the self-esteem scores of female students were higher than male students (P=0.05). Conclusion: The results of this research indicate that participation in physical activities may improve the self- esteem of bachelor students studying in Shiraz University. Furthermore, the analysis of the results showed that female students enjoyed higher self- esteem.

- چکیده انگلیسی: In most southern provinces of Iran, Soil Salinity is a growing problem particularly in the irrigated agricultural areas and has been found to reduce crop yields. In order to investigate the role of pod removal in seed germination, seedling growth and antioxidant enzymes activity in annual medics (Medicago scutella L.) under salinity stress conditions, a factorial experiment was conducted at College of Agriculture, Shiraz University in 2014 based on the completely randomized design with four replications. The factors included: 1) the presence or removal of seed pod, and 2) salinity stress at five levels involving controls 3, 6, 9 and 12 dS m-1. The results showed that salinity stress has caused the changes of germination, seedling growth and antioxidant enzymes activity. By increasing salinity stress levels, a significant reduction was observed in speed and percentage of germination as well as rootlet length, shoot length and seedling weight. However, the increased levels of salinity stress caused the increased antioxidant enzymes activity. Germination and seedling growth in seeds with no pod were more than seeds with pod, but about enzymes' activity, no significant difference was observed among seeds with and without pod, except for ascorbate peroxidase enzyme activity that was significantly more in seeds without pod as compared to the seeds with pod.

- چکیده انگلیسی: To decrease adverse effects of water deficit is foliar application with chemical agents such as silicon. However, there is low information on the influence of silicon on alfalfa under drought stress conditions. Thus, the current study was conducted to assessment the effect of different silicon concentrations (0, 1 and 2 mili Molar concentration) on alfalfa growth trend and biochemical traits, which grown under five level of irrigation regimes (100% as control, 85%, 70%, 55% and 40% field capacity; FC) according factorial experiment based on completely randomized design with four replication. The results showed that plant height, dry weight, chlorophyll a and b were reduced in response to water deficit; while water deficit increased chlorophyll a to b ratio as well as activity of superoxide dismutase and catalase in alfalfa crop. Also, water deficit up to 55% FC increased leaf silicon concentration, free proline, total soluble protein and peroxidase; however, severe water stress reduced them. Despite negative impact of water deficit, silicon application increased plant height, dry weight, soluble protein and three antioxidant enzymes as well as leaf silicon concentration. The positive effect of silicon on the most of the measured traits was greater at 2 mM than 1mM concentration, which might be due to higher silicon absorption at higher concentration. Alleviation ability of silicon was greater under severe water deficit compared to no or light water stress conditions. Our results suggested that although water deficit reduced growth and caused some changes in biochemical traits; silicon application, especially at 2mM concentration can be advised to alleviate some of the negative impact of water deficit.

- چکیده انگلیسی: Rational prescribing increases the quality of health care and patient outcomes. In this study, the quality of drug prescription in specialist physicians in Isfahan province of Iran was assessed for evaluating the rational use of drugs and improving the therapeutic outcomes.
This retrospective survey was conducted on a total of 7999530 prescriptions from all general and specialist physicians. The most frequently prescribed drugs and World Health Organization (WHO) prescribing indicators were evaluated in prescriptions of all medical specialties.
Assessment of prescribing indicators revealed poor-quality prescribing performance by general practitioners including high number of medicines prescribed per clients, wide range of prescribed medicines in each prescription, over-prescribing of antibiotics, corticosteroids and injectable drugs. There were also wide differences in the pattern of drug prescribing depending on the medical specialties. The average number of drugs prescribed per encounter by specialists was less than generalists except for the cardiologists. General practitioners, otorhinolaryngologists and general surgeons prescribed more antibiotics. Orthopedic surgeons and general practitioners were the top prescribers of injectable and corticosteroid drugs. The most frequently prescribed medicine groups varied according to the prescribers’ medical specialty. Analgesics and antipyretics were the most prescribed preparations in general medicine, pediatrics, orthopedics, general surgery and cardiology.
Because of the wide variability in the pattern of drug prescribing depending on the medical specialties, specific performance indicators should be developed for each specific medical specialty for better assessing of prescribing quality in specialist physicians.- انتشار مقاله: 07-10-1390

- چکیده انگلیسی: Objectives: The monitoring of cancer treatment response to chemotherapy is considered an essential strategy for follow-up of patients. The aim of this study was to evaluate the use of 99mTc-glucarate as a radiotracer for in vivo quantification and visualization of necrotic area and therapeutic effect of paclitaxel in ovarian cancer xenografted nude mice.
Materials and Methods: After implantation of human ovarian cancer (SKOV-3) in nude mice, tumor xenografted mice were enrolled in two groups as control and treatment (paclitaxel) groups. 99mTc-glucarate uptakes were quantified in tumors of control and treatment groups and also tumor imaging was performed with a gamma camera. The necrotic and viable areas of tumor and tumoral masses were evaluated through histopathological and macroscopic observations, respectively.
Results: 99mTc-glucarate uptake in tumor of treatment group was higher than control group.99mTc-glucarate uptake in ovarian tumor was clearly visualized with gamma imaging in both groups, but paclitaxel treated group showed higher radioactive uptake than control mice. The necrotic area in tumoral mass of mice treated with paclitaxel was confirmed by histopathological observations.
Conclusion: 99mTc-glucarate is an effective radiotracer for evaluation and monitoring of tumor necrosis caused by chemotherapy, and it may be helpful for therapy monitoring in patients with cancer.- انتشار مقاله: 12-04-1396

- چکیده انگلیسی: Drying of Matricaria recutita flower was investigated experimentally in a VibroFluidized Bed Dryer (VFBD). The aim of the present work was to optimize the best operating conditions for the drying of Matricaria recutita flower in the VFBD based on experimental design techniques. Response Surface Methodology (RSM) and Central Composite Design (CCD) based on 4-variable with 5-level have been employed to achieve the desirable possible combinations of frequency of vibration (7-15 Hz), inlet air temperature (36-68 °C), air flow rate (16-24 m3/h), and drying time (30-70 min) for the highest responses in terms of moisture removal (MR) and thermal efficiency (). A full quadratic model was used to describe the effects of individual and interactive parameters on the responses. The analysis of the obtained results showed that the inlet air temperature has the largest effect on responses. The optimal process parameters were as follows: frequency of vibration of 10.88 Hz, inlet air temperature of 64.08 °C, air flow rate of 20.63 m3/h and drying time of 69.11 min in which the predicted value for the MR (%) and (%) was 86.76 and 53.05, respectively. The proposed optimal conditions were examined in the laboratory and MR (%) and (%) achieved as 87.12±0.25% and 52.78±0.34%, respectively. The experimental values agreed with those predicted by RSM models, thus indicating the suitability of the model employed and the success of RSM in optimizing the drying conditions.

- چکیده انگلیسی: Background
Kangaroo Mother Care (KMC) is an easy and emotional care that can reduce the mortality and morbidity in premature infants, but often the relationship between mother and her newborn is delayed due to some barriers. The aim of this study was to investigate perceived benefits and barriers of mothers in this regard.
Materials and Methods: In this descriptive cross-sectional study, 121 mothers with premature infants admitted to the Neonatal Intensive Care Unit (NICU) of Yazd Shahid Sadoughi Hospital, Iran, studied using convenience sampling method in 2018. Data gathering accomplished by interviewing mothers using researcher-made questionnaire included baseline characteristics of parents and their infant and items measuring perceived benefits and barriers of mothers to KMC. The data were analyzed using SPSS software version 22.0
Results: Strengthening of the emotional relationship between mother and infant and a greater sense of confidence were the main perceived benefits of mothers. Not being in good physical and mental condition, lack of relevant knowledge and fear of performing KMC were the most important perceived barriers of mothers to KMC. The perceived benefits differed only in mother's ethnicity and father's occupation (P<0.05). The perceived barriers did not differ by any of demographic variables of parents and infants (P>0.05).
Conclusion
According to the results though the high perceived benefits of mothers in performing KMC, it seems that planning for improving mothers mental condition, providing mothers with necessary knowledge and reducing fear of caring can effectively promote doing KMC by mothers.- انتشار مقاله: 10-07-1397

- چکیده:
- چکیده انگلیسی: On Friday, December 26, 2003 at 1:55:56 GMT (5:25:56 local time), a powerful earthquake of moment magnitude (Mw) about 6.5 struck the ancient city of Bam and neighboring villages in the southeastern region of Iran. The highest death has been reported for this earthquake among all earthquakes in the world in the year 2003. About 70% of buildings in the city were damaged by the earth quake and more than 26000 people were killed. The main reason for such major damage may be weak adobe and brick structures. However, the damage was unexpectedly great for this magnitude. The city is located over low strength of fine grained soils such as silt with low cohesiveness and therefore, this is one of the main reasons for such large-scale destruction by the earthquake. This paper deals with the high damages in the city based on geology, tectonics and directivity of earthquake waves and also geotechnical parameters.

- چکیده انگلیسی: Background and Purpose: Dermatophytosis is one of the most common infections of skin, hair, and nails, caused by a group of keratinophilic fungi known as dermatophytes. Species identification of these fungi is of great significance from epidemiological and therapeutic points of view. The objective of the present study was to investigate dermatophytosis and its causative agents in patients, referring to the Central Mycology Laboratory of Yazd University of Medical Sciences, Yazd, Iran.
Materials and Methods: In total, 139 clinically suspected cases of dermatophytosis were examined during 12 months from February 2014 to February 2015. Skin scrapings were assessed through direct microscopic examinations and culture studies. Dermatophyte isolates were identified based on colony morphology on potato dextrose agar and dermatophyte test medium, nutritional requirements, urease and hair perforation tests, and microscopic characteristics on slide cultures.
Results: Dermatophytosis was mycologically confirmed in 26 (18.70%) out of 139 cases. Although there was a statistically insignificant difference between male and female subjects, men were dominantly affected. Infection was significantly common in the age group of ≤ 29 years (p <0.043). The most common clinical manifestation of dermatophytosis was tinea corporis (69.2%), followed by tinea cruris (15.4%), tinea manuum (11.5%), and tinea pedis (3.8%). Trichophyton mentagrophytes complex was the main etiologic agent (38.5%), followed by T. rubrum (23%), T. violaceum (15.5%), T. verrucosum (11.5%), Microsporum canis (7.7%), and Epidermophyton floccosum (3.8%).
Conclusion: In comparison with previous research, epidemiology of dermatophytosis has changed in Yazd over the past decades. Therefore, periodical investigations on the epidemiological aspects of this infection are required for efficient control and prevention of this cutaneous dermatophytic disease.- انتشار مقاله: 18-04-1398
