Objective This study aims to investigate the complications due to misoprostol administration for second-trimester termination of pregnancy among women with history of 2 or more cesarean scarring. Methods The cohort of this retrospective study included 678 subjects who required second-trimester pregnancy termination, from 2013 to 2015 and treated with vaginal misoprostol of 100 to 400 μg. The subjects were divided into 3 groups based on their history of cesarean sections: without a history of cesarean section, with a history of one cesarean section, and with a history of more than one cesarean section and uterine scaring. Results The results showed that the success rate of misoprostol administration for pregnancy termination was 95.72%. The rate of bleeding as a complication was significantly higher in subjects with a history of more than one cesarean section than in other participants (risk ratio [RR], 2.24; 95% confidence interval [CI], 1.11-4.0). The incidence of uterine rupture was higher in the group with a history of more than one cesarean section than in other groups. However, no significant difference was observed between the groups (RR, 1.44; 95% CI, 0.27-7.6). There was a significant relationship between the need for other auxiliary treatments in the pregnancy termination and the history of uterine scarring (RR, 3.3; 95% CI, 1.23-9.1). Conclusion The present study showed that pregnancy termination using smaller divided dose of misoprostol in patients with previous history of cesarean scarring may be associated with lower incidence of uterine rupture.

Marzieh Rezazadeh,Ramin Ostadi 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.10

The effect of stenosis for a carotid artery bifurcation with elastic and rigid walls is investigated numerically. In the present study, the blood flow is considered as a laminar pulsatile flow. The effect of fluid-solid interaction is carried out using ANSYS-FLUENT software. The results show that the maximum wall shear stress in the stenosed artery is three times higher than that of a healthy artery. The shear stress gradient in elastic arteries Is lower than in rigid arteries. For rigid artery, the return flow and separation length in the diastolic phase is lower than the systolic phase.

Marzieh Khanmohammadi 세계문화관광학회 2011 Conference Proceedings Vol.12 No.-

As more tourism destinations emerge and competition for visitors becomes more intense a destination's ability to project itself on the world stage and differentiate itself from others is ever more important. London has undoubtedly the highest popularity among international tourists.It is also dominant in terms of the amount of heritage-related investment. So brandig London not only as a real cultural capital but also as one of the coolest global cities as the hospitable and safe multi-cultural host of the 2012 Olympics is very important for UK tourism development. This new brand image is so different from the traditionally held view of the city of Harrods the Royal Family. The study aims to discuss the following objectives: Reviewing the literature of branding destinations and related concepts; The advantages of branding London city as a means of promoting the city's features positive image and benefits by giving an example of successful destinations in branding management process. The importance of branding for 2012 Olympic Games The result of the study shows that the real competition between tourism destinations based on intangible to urism services such as providing tourists expectation security satisfaction and positive image which happens by branding the destination image as a safe and hospitable location. Therefore in order to enhance tourism in london as a UK dominant heritage site the tangible and intangible tourism services and attractions should be combined together.

In this research, changes were observed in cell surface proteins of a typical strain of the Lactobacillus casei was investigated in response to acidic growth conditions. Two dimensional electrophoresis and Western blot analyses were carried out to detect changes in relative abundance of proteins at the cell surface. The identity of the differentially expressed proteins extracted by LiCl, a chemical routinely used to extract surface proteins of lactic acid bacteria, was determined by MALDI-TOF/TOF MS. Many enzymes involved in glycolysis were up-regulated in the cell surface fraction following growth at low pH, including enolase,lactate dehydrogenase, and glyceraldehyde-3-phosphate dehydrogenase. Several of these proteins were also related to adhesion and generalized stress responses. It is demonstrated that growth of L. casei under acidic conditions caused molecular changes at the cell surface to develop an adaptive strategy corresponding to slower growth at low pH.

A Generalized Analytical Method to Evaluate the Post-limit Properties of Joints in Bending Moment According to Eurocode3

On the structural analysis, connection eff ects should be evaluated in terms of rotational stiff ness and ultimate strength; this makes it possible to obtain realistic behavior of the structure. In this research, a simple analytical evaluation is carried out to predict the behaviors of the connections as a bi-linear curve. Mechanical properties of the initial and the second parts of this curve are obtained by component-based method and a suggested classifi cation method, respectively. The component-based method represents a joint by using a combination of rigid and fl exible components. Each of the components is modeled by means of specifi c stiff ness and strength values and they are assembled together to obtain the initial mechanical properties of the joint. The suggested classifi cation method classifi es all the components in a connection into three groups based on comparing the ultimate and the design moment strength of each component with those of the connection. By considering this procedure, a new equation is proposed to determine joint post-limit rotational stiff ness. This simple and fast method is applicable to any type of joints regardless of profi le type and applied loading. The proposed method is applied to a bolted angle, an end-plate to rectangular hollow section column and two bolted end-plate beam-to-column connections. The results are compared with those obtained from some other analytical, numerical and experimental methods. The outputs confi rm that the proposed method is simpler, more accurate and less time consume than the other methods.

Injective property relative to nonsingular exact sequences

Marzieh Arabi-Kakavand,Shadi Asgari,Yaser Tolooei 대한수학회 2017 대한수학회보 Vol.54 No.2

We investigate modules $M$ having the injective property relative to nonsingular modules. Such modules are called ``$\mathcal N$-injective modules''. It is shown that $M$ is an $\mathcal N$-injective $R$-module if and only if the annihilator of $Z_2(R_R)$ in $M$ is equal to the annihilator of $Z_2(R_R)$ in $E(M)$. Every $\mathcal N$-injective $R$-module is injective precisely when $R$ is a right nonsingular ring. We prove that the endomorphism ring of an $\mathcal N$-injective module has a von Neumann regular factor ring. Every (finitely generated, cyclic, free) $R$-module is $\mathcal N$-injective, if and only if $R^{(\mathbb N)}$ is $\mathcal N$-injective, if and only if $R$ is right $t$-semisimple. The $\mathcal N$-injective property is characterized for right extending rings, semilocal rings and rings of finite reduced rank. Using the $\mathcal N$-injective property, we determine the rings whose all nonsingular cyclic modules are injective.

Objectives: The age of menopause is affected by several factors. In this study we aimed to identify the age of natural menopause and its related factors in a large-scale population-based cohort in Iran. Methods: In this study, a subset of data collected during the enrollment phase of the Tabari cohort study was utilized. Reproductive history and other related data were collected using a structured questionnaire. Blood samples were obtained from all participants. Data were analyzed using chi-square test, independent t test, and ANOVA as well as a multivariate linear regression model. Results: Among participants of the Tabari cohort, 2,753 were menopausal women. The mean age of natural and induced menopause was 49.2 ± 4.7 and 43.2 ± 6.4 years, respectively (P = 0.001). The number of pregnancies, duration of breastfeeding, level of education, residency, presence of thyroid disease, and body mass index affected the age of menopause. After adjustments for confounding variables, the number of pregnancies remained significantly associated with late menopause. Conclusions: The age of natural menopause in this study was similar to that in other studies, and the number of pregnancies was positively associated with the age of menopause after adjustments for confounding variables.

Marzieh Saei Ghare Naz,Fatemeh Alsadat Rahnemaei,Fahimeh Ramezani Tehrani,Fatemeh Sayehmiri,Vida Ghasemi,Mojdeh Banaei,Giti Ozgoli 대한산부인과학회 2023 Obstetrics & Gynecology Science Vol.66 No.5

Nowadays, polycystic ovary syndrome (PCOS) and cognitive dysfunction are major health problems among female. This narrative review aimed to investigate cognitive dysfunction in female with PCOS. English and Persian articles published in PubMed, Scopus, Web of Science, Google Scholar, PsycINFO, Scientific Information Database, and Cochrane Database of Systematic Reviews until May 2022 were searched. Sixteen studies involving 850 female with PCOS and 974 controls were assessed. In these studies, the association between biochemical factors and symptoms of PCOS and memory, attention, executive functioning, information processing speed, and visuospatial skills was evaluated. The literature review revealed the possible cognitive changes in female with PCOS. This study summarized the different aspects of cognitive function in female with PCOS due to medication, psychological problems (mood disorders caused by disease symptoms and complications), and biochemical markers, such as metabolic and sex hormone abnormalities. Considering the existing scientific gap regarding the possibility of cognitive complications in female with PCOS, further biological studies should be conducted to evaluate the potential mechanisms involved.
