- چکیده:
- چکیده انگلیسی: One of the most common methods to identify and represent oneself, especially in contemporary era, is cultural consumption. In cultural consumption, people often consume a variety of valuable goods and symbols, not because of their material value but due to their cultural one in order to create desirable images of themselves in the minds of others. In the meantime, the choice of a particular pattern of cultural consumption or cultural practices or preferences requires cultural resources or cultural capital; or in other words, cultural consumption needs cultural resources and cultural capital. In the present study, the statistical population including 15-29 year olds in Yasuj and a sample size of 379 people were selected. Amos software was used to analyze the data. The results suggested that, there is a relationship between independent variables (religiosity, cultural capital, social capital and socio-economic status), and the consumption of cultural goods. The output of the model also indicates that the variable of cultural capital (0.32) has explained the highest amount of variance of cultural consumption. Moreover, the variables of social capital and religiosity explained 18% and -18 %t of the variance of cultural consumption in the workplace.

- چکیده:
- چکیده انگلیسی: Fiber-reinforced polymer (FRP) material is currently being produced in different configurations and widely applied to strengthening and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips) bonded into pre-cut grooves applied to the concrete cover of the elements to be strengthened. These FRP bars can help increase the flexural and shear capacity of existing concrete members as well. This article aims to present the experimental and numerical results gained separately from un-strengthened and strengthened beams under bending loading. In the experimental part, two large-scale fixed-end support reinforced concrete beams of the same size, and reinforcement characteristic was designed, constructed, and tested under one point concentrated loading system. The first specimen used as a control specimen while the second served as the strengthened applying NSM method with a new proposed hand-made CFRP Bar in the laboratory. Moreover; an extra analytical work was carried out using calibration of the analytical models as per the obtained experimental test results. The results and Photographs taken at the selected stages of loading are indicative of the fact that NSM method with FRP bars can be effectively applied to the existing structures in order to increase their flexural capacity, change their crack pattern and decrease final deflection.

- چکیده:
- چکیده انگلیسی: Purpose:Dental shade guides are commonly used for color determination and should be disinfected and sterilized. The purpose of this study was to evaluate the color change of Vita 3D Master shade tabs after disinfection and sterilization. Material and methods:Overall, 98 samples (shade tabs) were randomly selected from 14 new, unused Vita 3D sets, including the following shades: 2M1, 3L1.5, 3M1, 3M2, 3M3, 3R1.5 and 4M1. In each set, values of 2, 3 and 4, chroma of 1, 2 and 3 and hue were selected for the comparison of different shades. All tabs were measured using the Vita Easyshade device at baseline. The first group was disinfected with Deconex and the second group was sterilized by autoclaving in a simulated annual application. All the tabs were measured again using the same device. This process was repeated to simulate 2 and 3 years of usage. Statistical analysis was conducted by repeated measures analysis of variance (ANOVA) and independent t-test and paired sample t-test. Results:In the disinfected group, we observed significant differences in value and chroma in all periods (p˂0.001). However, hue showed no significant difference after the first year of simulated treatment (p=0.527), though it was significantly different in the second and third simulations (p˂0.001). In the sterilized group, all variables showed a significant difference for each year (p˂0.05). Considering total color difference (ΔE), there was a significant difference between the two groups in the first, second and third simulated years; ΔE increased in the sterilized group more than in the disinfected samples (p˂0.001). Conclusions: The color change of shade tabs was significant both after disinfection by a chemical solution and by sterilization through autoclaving. However, although disinfectants may not have a clinically important effect, sterilization should be considered as an interfering factor during color-matching procedure.

- چکیده انگلیسی: Background: Major Depression Disorder (MDD) is a common disorder with preva-lence of 15% among men and up to 25% among women. In recent years the association of immune system alterations and MDD has been investigated. Assessments of immu-nologic and inflammatory responses in these patients enhance our knowledge of the eti-ology and pathogenesis of this disease.
Objective: To investigate the changes in immu-noglobulin and cytokine serum levels and lymphocyte subsets in patients with MDD.
Methods: We studied 37 adult patients with MDD, diagnosed based on DSM-IV diag-nostic criteria, and 15 healthy controls matched with the patients. Plasma concentration of interleukin-4 (IL-4), IL-10, TNF α, and IFN γ were measured by ELISA and serum immunoglobulins by SRID. Total number of NK cells (CD16 and CD56), B cells (CD19), and T cells (CD8, CD4, and CD3) were determined by flow cytometry.
Results: We found no significant differences in plasma concentration of IL-4, IL-10, TNF-α, IFN-γ, and immunoglobulins as well as total number of NK cells, B cells, and T cells between major depressed patients and healthy control subjects.
Conclusion: We conclude that in our patients, there were no significant differences in immune system ac-tivity between MDD patients and controls.- انتشار مقاله: 17-05-1395

- چکیده انگلیسی: A simple, inexpensive and efficient method was used for extraction and determination of Fexofenadine and Levocetirizine with three–phase hollow fiber liquid-phase microextraction and high-performance liquid chromatography. Several parameters influencing the extraction recoveries such as the nature of organic extraction solvent, pH of donor and acceptor phases, stirring rate, extraction time and salt addition to the sample solution (donor phase) were investigated and optimized. Under the optimized conditions (toluene as organic solvent, pHdonor = 2.5, pHacceptor = 12.0, stirring rate of 1000 rpm, extraction time of 30 min, with no salt addition), extraction recoveries were 64% for Fexofenadine and 79% for Levocetirizine. A good clean-up sample with excellent linearities in the range of 1–500 ng/mL for Fexofenadine (R2=0.997) and 0.6-600 ng/mlfor Levocetirizine (R2=0.998) were obtained. The limits of detection were 0.3 ng/mL for Fexofenadine and 0.2 ng/mL for Levocetirizine.

- چکیده:
- چکیده انگلیسی: Myelomeningocele is a condition caused by the disjunction of neuroectoderm and ectoderm during embryogenesis. It can lead to neuronal structure disorders such as kyphosis and scoliosis, with scoliosis being more common. Kyphosis is found in 10-15% of these patients and can cause poor clinical consequences. The annual progression of Kyphosis is approximately 8 to 12 degrees. Kyphosis is a limiting factor in rehabilitation due to the inability of the patients to sit in wheelchairs and in the apex of the kyphotic region. This study aims to report a similar condition in a 14-year-old Iranian boy who underwent surgery for posterior kyphectomy. In the majority of cases with kyphosis, anterior wedging occurs in the vertebral body where the apex of the deformity is located. In the studied patient, the deformity had a round curve with no definite apex to mark out. These deformities need special surgical approaches and postoperative care.

- چکیده:
- چکیده انگلیسی: Background: Vesicoureteral reflux (VUR) is a common condition among children. Although, subureteral injection is a minimally invasive new method for VUR treatment, ideal bulking agent in endoscopic treatment still remains controversial. We aimed to evaluate VANTRIS subureteral injection efficacy in VUR treatment in pediatric patients.
Materials and Methods: All patients who referred to Imam Khomeini hospital in Urmia-Iran, Urology ward with VUR diagnosis that had indications for open surgery, enrolled study (during Mar 2013 to Mar 2015). Prior to intervention, VUR severity, urinary tract infection (UTI) and subsequent complications determined using urine analysis and imaging. Subsequently, single injection of the VANTRIS performed for all patients and patients underwent six-month follow up including several clinical and paraclinical evaluations.
Results: 31 patients with VUR diagnosis participated; of 31 patients, 18 (58.06%) children with primary UTI who had surgery indication enrolled study; of 18 patients, seven patients (38.88%) were boy and eleven patients (61.12%) were girl with mean age of 6.88 ± 2.61 years, and out of 29 refluxing rental units (RRU), 13 (44.8%) were right and 16 (55.2%) were left kidney. In current study, patients divided to two subgroups regarding their age older than five or younger than five years old and there was no significant difference between the resolution rates following VANTRIS injection in two groups (P>0.05). Eleven (38.88%) RRU detected in boy patients, nonetheless VUR resolved in all of them, postoperatively. On the other hand, of 18 RRU in female patients, complete VUR resolution observed in 16 kidneys (88.8 %), but only 2 (11.11%) kidneys had incomplete, but significant VUR resolution, where no significant difference observed. The prevalence of reflux in patients with UTI was 30% and in patients without UTI was 17%.
Conclusion: The current study indicated that in all age groups of patients, the subureteral injection of the VANTRIS was an accurate and effective treatment modality for VUR- انتشار مقاله: 22-06-1395
