- چکیده انگلیسی: Mental health is one of the most important of health components.Mental and behavioral diseases are major disease burdens. Women make up half of the world's population and raise the other half. While women are an integral part of societies, their diverse roles put them at a higher risk of psychological issues The 8th conference on women's health was the collaboration of Health Policy Research Center, affiliated with Shiraz University of Medical sciences, and Health Promotion and Women’s Health workgroup affiliated with the Academy of Medical Sciences. It is believed that we must move towards promoting and broadening women's health issues beyond the sole reproductive and sexual rights. Through a coordinated action, which has involved all concerned stakeholders including governmental health, social, and economic sectors, local authorities and stakeholders, industries, NGOs, volunteers, and the media aiming to enhance women’s mental health, the conference had three priorities: 1) family cohesion and lifestyle, 2) vulnerable women, and 3) resilience.

- چکیده:
- چکیده انگلیسی: In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4. The pristine and amine-functionalized NaY zeolites were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and N2 adsorption. The results showed that the structure of zeolite was preserved after amine modification. The adsorption capacity of CO2 and CH4 on these adsorbents was measured by the volumetric method at 298 K and 348 K. In comparison to CH4, CO2 was preferentially adsorbed on these adsorbents. the results demonstrated that incorporation of amines into zeolites structure improved significantly the selectivity towards carbon dioxide so that the optimal selectivity of CO2 over CH4 reached to 4.04 on zeolite modified with 2-methylaminoethanol at 348 K. Chemical interaction between adsorbate and sorbents as well as the steric effects were assessed to be the main reasons of high selective adsorption of carbon dioxide on amine-functionalized zeolites. Two of the most common adsorption models, the Langmuir and Sips isotherms, were used to correlate the experimental data of CO2 adsorption on the adsorbents The results revealed that the amine-functionalized NaY zeolites could be a good sorbent for use in flue and natural gas separation processes.

- چکیده:
- چکیده انگلیسی: In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a significant increase in the CO2 adsorption capacity. The CO2 adsorption capacity of the amine- modified NaY increased with temperature. The mechanism of CO2 adsorption on NaY is usually a physical interaction, but it seems that after amine modification, chemical mechanism is the dominant mechanism for the chemical interaction between CO2 and amine groups. The adsorbents were characterized by surface area and porosity analysis, X-ray diffraction, Fourier transform infrared spectroscopy, thermal gravimetric analysis, and scanning electron microscopy. The CO2 adsorption capacity was measured by the volumetric method at 298 and 348 K. The CO2 adsorption capacity of TEPA-NaY, DEA-NaY, and 2-MAE-NaY at 298 K was 60.63. The CO2 adsorption capacity of TEPA- NaY, DEA-NaY, and 2-MAE-NaY at 348 K were 92.9, 78, and 85.42, respectively. These results showed that amine-functionalized NaY zeolites have excellent adsorption potential for CO2 adsorption at high temperatures.

- چکیده:
- چکیده انگلیسی: Background & Objective:
Malignant breast tumors, which are one of the most important deadly cancers in women, like many other cancers, are proposed to be related to viruses etiologically. Proper management of breast carcinoma necessitates an identification of the etiological factors. Human Papilomavirus is considered to have an etiological role in breast carcinoma. We carried out this study to find out if Human Papilomavirus-DNA is present in the malignant and benign breast tissue in our patients.
Methods:
Seventy five paraffin-embedded breast cancer tissues and 75 normal breast tissues and benign breast lesions were examined in this study (case-control) to look for Human Papilomavirus-DNA employing Nested Polymerase Chain reaction. The tissues were examined over a period of ten years in the pathology department of the Pathobiology Laboratory Center of Tehran.
Result:
No Human Papilomavirus-DNA was found in any of the malignant or control group specimens.
Conclusion:
Our results showed no evidence of Human Papilomavirus in cancerous and benign tissues, which is consistent with some other studies in English medical literature. More investigations using more specimens from different parts of the country are required to confirm the presence or absence of any connection between Human Papilomavirus and development of breast carcinoma in Iran.- انتشار مقاله: 19-04-1397

- چکیده:
- چکیده انگلیسی: Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma in our center, which is one of the referral centers in Tehran.
Methods: In this retrospective study, we analyzed the results of prostate needle biopsies and subsequent prostatectomies diagnosed at the Pathobiology Laboratory Center, Tehran, Iran in 45 patients between 2002 and 2013. Preoperative clinical data and theinformation from biopsy and prostatectomy specimens were collected.The accuracy, sensitivity, specificity, and positive and negative predictive values of different grades and groups were assessed. Pearson and Spearman correlation coefficient were used to determine the relation of different variables.
Results: The biopsy Gleason score was identical to the scores in prostatectomy specimens in 68.2% cases, while 31.8% were discrepant by 1 or 2 Gleason score. We had 9.1% downgrading and 22.7% cases upgraded after prostatectomy. The sensitivity and positive predictive value was 86% and 79% for low grade, 67% and 75% for moderate grade, and 80% and 80% for high-grade tumors, respectively. Conclusion: Overall, the reliability of Gleason grading of needle biopsies in predicting final pathology was satisfavory. Moderate grade group was the most difficult to diagnose in needle biopsy.- انتشار مقاله: 11-02-1394

- چکیده:
- چکیده انگلیسی: The present study aimed to examine the effective factors in the rank of national entrance exam of the candidates in state universities and higher education institutes in Iran in the form of a multilevel analysis. Therefore, the data of 5000 candidates was gathered randomly from five experimental groups in the national examination of 2017. The HLM7.30 software was used for multilevel data analysis. The results revealed that among the provinces, there were significant differences in the average national ranks of the candidates in Math, Humanity, Art, and English experimental groups. However, there was not any significant difference in the Science group. In the Math group, the average scores of the third year of high school, the total average of diploma, the entrance quota, and gender determined 58.44 percent of the whole variance of the national rank at level one. In the Humanity group, the average scores of the third year of high school, the total average of diploma, and gender explained 49.22 percent. In the Art group, the total average of the third year of high school, the entrance quota and gender were 15.8 percent; and finally in the English group, the average scores of the third year of high school, the total average of diploma, the entrance quota, and gender were wholly 31.45 percent. There was not any relationship between the age of the candidates as well as the time interval between their graduation and the entrance exam with their national rank. In the Humanity group, only in the local districts and among the other groups, in poles and local districts, the national rank of the candidates was different. In the Science group, only the third year high school’s average scores of the candidates could predict the national rank.

- چکیده:
- چکیده انگلیسی: Background: Magnetic nanoparticles (MNPs) loaded by various active compounds can be used for targeted drug delivery.
Objectives: In the present study, the Fe3O4 magnetic nanoparticles that contained gentamicin were prepared and their antibacterial activities were studied.
Materials and Methods: MNPs containing gentamicin (G@SA-MNPs) were prepared using sodium alginate (SA) as a surface modifier. After and before coating, the prepared MNPs were characterized using transmission electron microscopy (TEM), X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM). Finally, the antibacterial effect of the MNPs was investigated by a conventional serial agar dilution method.
Results: Particle size distribution analysis showed that the size of MNPs, before and after coating, was in the range of 1-18 nm and 12-40 nm, respectively. The magnetization curve of G@SA-MNPs (with saturation magnetization of 27.9 emu.g-1) confirmed ferromagnetic property. Loading gentamicin on the surface of MNPs was qualitatively verified by FTIR spectrum. Quantitative analysis measurements indicated the gentamicin loading on SA-MNPs as 56.7 ± 5.4%. The measured MICs of G@SA-MNPs for Pseudomonas aeruginosa (PTTC 1574) was 1.28 μg.mL-1. The sub-MIC (0.64 μg.mL-1) concentration of G@SA-MNPs in nutrient broth could successfully inhibit the growth of P. aeruginosa for 14 hours.
Conclusions: Loading gentamicin on the SA-MNPs exhibited reasonable antibacterial effects against P. aeruginosa.
