Objective To calculate couple-year of protection （CYP） by conversion coefficient （F） of tubectomy and vasectomy in urban and rural regions of Iran. Methods A total of 103 450 married women aged 10-49 years in 2005 across urban and rural regions of lran were sampled by multi stage cluster sampling. The data were collected by household survey and direct interview and analyzed by STATA8.0 software and survey analysis commands. Results Mean age of the women at the time of tubectomy estimated 31.9 years and conversion coefficient of tubectomy was 17.1 ±0.1. Mean age of women at the time of her husband vasectomy estimated 31.48 years and its conversion coefficient was 17. 5 ± 0. 1. Cluster analysis defined different regions of Iran on the basis of evaluated conversion coefficients of tubectomy and vasectomy which both of them presented seven clusters. Literacy of women and total coverage of family planning in a region had a direct relationship with this conversion coefficient （P〈0.05）. Conclusion The variations observed in the conversion coefficients and their dissimilarity among different regions of Iran may be due to a variety of fundamental factors of which literacy and culture are of important factors.

Ebola virus （EBOV） is the causative agent of a severe hemorrhagic fever disease associ- ated with high mortality rates in humans. This virus has five strains of which Zaire Ebola virus （ZEBOV） is the first and most important strain. It can be transmitted through contact with contaminated surfaces and objects. The genome of EBOV codes one non- structural and seven structural proteins consisting of two forms of glycoprotein （GP）： soluble glycoprotein （sGP） and GP （spike）. In this paper, we attempted to characterize and predict physicochemical properties, B-cell epitopes, mutation sites, phosphorylation sites, glycosylation sites, and different protein structures of EBOV GP to provide com- prehensive data about changes of this GP during a 40-years course （1976-2015）. GP sequences were obtained from NCBI gene bank from 1976-2015. Expasy＇sProtParam, PROTSCALE, immuneepitope, Bepipred, BcePred, ABCpred, VaxiJen, DISPHOS, Net- Phos, and numerous programs were used to predict and analyze all sequences. More variety of mutations were found in 2015 sequences and mutations were related to huge changes in B-cell epitopes, phosphorylation and glycosylation sites. In addition, our results determined different sites of disulfide bonds and an important mutation related to IgE epitope as well as four potent B-cell epitopes （380-387, 318-338, 405-438 and 434-475）. In this study, we suggested the effect of mutations on GP properties, six posi- tions for disulfide bonds and four phosphorylation sites for protein kinase C enzyme. Selected sequences were shown different sites for O-link and N-link glycosyl^tion. A mutation that changed GP to an allergen protein and has a significant role in vaccine designing as well as four potent B-cell epitopes in GP protein were found.

Effect of Laser Fluence on the Characteristics of Ag Nanoparticles Produced by Laser Ablation

引用

Soft Nanoscience Letters 2013年第4期3卷 93-100页

作者： Davoud Dorranian Shiva Tajmir farzane Khazanehfar Laser Lab. Plasma Physics Research Center Science and Research Branch Islamic Azad University Tehran Iran.

6-12 nm silver nanoparticles were synthesized by the pulsed laser ablation of a high purity silver bulk in distilled water. Effect of laser fluence on the size, morphology and structure of produced nanoparticles has been studied experimentally. Pulses of a Q-switched Nd:YAG laser of 1064 wavelength at 7 ns pulse width at different fluences were employed to irradiate the silver target in water. The UV-Visible absorption spectra of the Ag nanoparticles exhibit surface plasmon resonance absorption peak in the UV region. TEM and SEM micrographs, in a good agreement with DLS results, indicate that with increasing the laser fluence the average size of spherical Ag nanoparticles is decreased. It is found that Ag nanoparticles exhibit photoluminescence emission with two peaks because of the inter band transition and electron-hole recombination.

Health 2012年第4期4卷 233-236页

作者： Masoud Seyedian farzane Ahmadi Atefeh Lalvand Mohammad Nourizadeh Cardivascular disease research center Ahvaz joundishapour university Ahvaz Iran

Introduction: As no data is available concerning the cut-off value defining abnormal pulmonary artery systolic pressure (PASP) response in subjects of various ages, the aim of this study is to assess physiological PASP response to exercise in healthy individuals of various ages. Material and methods: One hundred and twenty three healthy volunteers, aged 30 to 70 years, underwent Doppler echocardiographic measurements at rest and after treadmill exercise test. Pulmonary artery systolic pressure was estimated at rest, and immediately after peak exercise using Bernoulli formula (four times tricuspid valve regurgitation velocity squared adding an estimated right atrial pressure). Results: Lower and upper limits of PASP during rest was 7 and 28 mmHg and after peak exercise was 14 and 48 mmHg respectively. After exercise, PASP increased from rest (14 ± 4 mmHg) to peak (25 ± 7 mmHg). Pulmonary artery systolic pressure during rest and peak exercise, increased with age, but has no correlation with body mass index or gender. Conclusion: Pulmonary artery systolic pressure at peak exercise can frequently reach values ≥ 30 mmHg in healthy individuals with good exercise capacity, especially in elderly individuals, which goes beyond pathologic definitions of pulmonary hypertension.

How Vaginal Infections Impact Women’s Everyday Life <br/>—Women’s Lived Experiences of Bacterial Vaginosis and Recurrent Vulvovaginal Candidiasis

Advances in Sexual Medicine 2017年第1期7卷 1-19页

作者： Annsofie Adolfsson Anna Hagander farzane Mahjoubipour Per-Gö ran Larsson School of Health Sciences Orebro University Orebro Sweden University College of Southeast Norway Tonsberg Norway Master student Midwifery University College Skovde Sweden Department of Obstetrics and Gynaecology Skaraborg Hospital Skovde Sweden University of Linkö ping Link&ouml ping Sweden

Reoccurring symptoms and persistent problems that continue post treatment can be characteristic of the vaginal infections Bacterial Vaginosis (BV) and recurrent vulvovaginal candidiasis (RVVC). The purpose of this study was to describe women’s life experiences in managing the symptoms of bacterial vaginosis and Candida. Sixteen women were recruited and participated in an interview study when they contacted a Swedish gynecology clinic with vaginal complaints that ranged from and included abnormal discharge, irritation itching along with serious malodor. An interpretive phenomenological approach was used with an individual interview to get a more intimate understanding of the women experiencing these problems. The finding of this study shows that managing the recurrent symptoms of the infections remains to be a challenge for women as it has a clearly negative impact on the quality of their lives. Four themes developed: frustration and mood disorders, intimacy changes in the relationship, exposure, hope and relief. The women had high hopes of eliminating the symptoms within the six-month study period. The treatment program, with its well-developed guidelines and continuity of care within the context of the study greatly improved the quality of life of these women. Women had feelings of frustration and anxiety when nothing could cure their problem while they had also a great hope to get rid of the symptoms with a long striking treatment. Well-developed guidelines and continuity of care can help these women to have an improved quality of life.
