Tumor Targeting via siRNA-COG3 to Suppress Tumor Progression in Mice and Inhibit Cancer Metastasis and Angiogenesis in Ovarian Cancer Cell Lines.

BACKGROUND: The COG complex is implicated in the tethering of retrograde intra-Golgi vesicles, which involves vesicular tethering and SNAREs. SNARE complexes mediate the inva-sion and metastasis of cancer cells through MMPs which activate growth factors for ECM frag-ments by binding to integrin receptors. Increasing MMPs is in line with YKL40 since YKL40 is linked to promoting angiogenesis through VEGF and can increase ovarian cancer (OC) resistance to chemotropic and cell migration. OBJECTIVE: The aim of this study is an assessment of siRNA-COG3 on proliferation, invasion, and apoptosis of OC cells. In addition, siRNA-COG3 may prevent the growth of OC cancer in mice with tumors. METHODS: Primary OC cell lines will be treated with siRNA-COG3 to assay YKL40 and identified angiogenesis by Tube-like structure formation in HOMECs. The Golgi morphology was analyzed using Immunofluorescence microscopy. Furthermore, the effects of siRNA-COG3 on the prolifer-ation and apoptosis of cells were evaluated using MTT and TUNEL assays. Clones of the HOSEpiC OC cell line were subcutaneously implanted in FVB/N mice. Mice were treated after two weeks of injection of cells using siRNA-COG3. Tumor development suppression was detected by D-luciferin. RT-PCR and western blotting analyses were applied to determine COG3, MT1-MMP, SNAP23, and YKL40 expression to investigate the effects of COG3 gene knockdown. RESULTS: siRNA-COG3 exhibited a substantial effect in suppressing tumor growth in mice. It dra-matically reduced OC cell proliferation and triggered apoptosis (all p < 0.01). Inhibition of COG3, YKL-40, and MT1-MPP led to suppression of angiogenesis and reduction of microvessel density through SNAP23 in OC cells. CONCLUSION: Overall, by knockdown of the COG3 gene, MT1-MMP and YKL40 were dropped, leading to suppressed angiogenesis along with decreasing migration and proliferation. SiRNA-COG3 may be an ideal agent to consider for clinical trial assessment therapy for OC, especially when an antiangiogenic SNAR-pathway targeting drug.

Role of S100 and YKL40 on Intraventricular Cerebral Hemorrhages in the Preterm Infant and the Neuroprotective Role of miR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 in Neonatal Mice with Nerve Injury.

BACKGROUND: Epilepsy and intraventricular-cerebral hemorrhage is a common complication irreversible in preterm infants. Inflammation leads to an increase in intracellular calcium, acidosis, and oxygen usage, and finally, may damage brain cells. Increases in HIF-1a and HVCN1 can reduce the complications of oxygen consumption and acidosis in infants with intraventricular hemorrhage (IVH). On the other hand, decreases in S100B can shield nerve cells from apoptosis and epilepsy by reducing brain damage. OBJECTIVE: In this research, we investigated how miR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 affect apoptosis in hypoxic mice. METHODS: On the first and third days after delivery, the YKL40, HIF-1a, HVCN1, and S100b genes were compared between two groups of preterm infants with and without maternal inflammation. Afterward, the miRNAs were transfected into cell lines to monitor variations in YKL40, HIF-1a, HVCN1, and S100b gene expression and nerve cell apoptosis. We changed the expression of S100b, HVCN1, and HIF-1a genes by using specific siRNAs injected into mice. Using real-time PCR, Western blotting, flow cytometry (FCM), and immunofluorescence, and changes in gene expression were evaluated (IHC). RESULTS: HVCN1 gene expression showed a strong negative correlation with epilepsy in both groups of infants (P<0.001). Significant correlations between epilepsy and the expression levels of the S100b, YKL40, and HIF-1a genes were found (P<0.001). According to FCM, after transfecting miRNA-431 and miRNA-34a into cell lines, the apoptosis index (A.I.) were 41.6 3.3 and 34.5 5.2%, respectively, while the A.I. were 9.6 2.7 and 7.1 4.2% after transfecting miRNA-21 and miRNA-138. MiR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 were simultaneously injected into hypoxic mice, and IHC double-labeling revealed that this reduced apoptosis and seizures compared to the hypoxic group. CONCLUSION: Our findings demonstrate that miR-138-siRNAs-HIF-1a and miR-21-siRNAs-HVCN1 injections prevent cerebral ischemia-induced brain damage in hypoxia mice by increasing HVCN1 and HIF-1a and decreasing S100b, which in turn lessens apoptosis and epilepsy in hypoxic mice.

Maternal mental health concerns during the COVID-19 pandemic in Iran: a content analysis study.

BACKGROUND: As crises occur, attention to physical health usually becomes more than mental health, neglecting mental health, especially in some vulnerable groups such as pregnant women and new mothers, can have adverse consequences. Therefore, it is imperative to recognize and comprehend their mental health needs, particularly during critical situations such as the recent COVID-19 pandemic. The aim of this study was to explain the understanding and experience of mental health concerns faced by pregnant and postpartum women during this pandemic. METHODS: This qualitative study was conducted from March 2021 to November 2021 in Iran. Data were collected using semi-structured in-depth interviews to understand mental health concerns in pregnancy and the postpartum period during the COVID-19 pandemic. Twenty-five purposefully retrieved and participated in the study. Due to the prevalence of coronavirus, most of the participants preferred tele interviews. When data saturation was achieved, the data were codified manually and analyzed using Graneheim and Lundman's approach 2004. RESULTS: Based on the content analysis of the interviews, 2 main themes, 8 categories 23 subcategories were identified. The identified themes were as follows: (1) Maternal mental health threats and (2) Inadequate access to the required information. CONCLUSION: The results of this study showed that the main concern and fear of pregnant and postpartum women in the COVID-19 pandemic was the fear of the possibility of death for themselves and/or their fetus/infant. The knowledge that was obtained from the understanding of pregnant women and new mothers about the mental health concerns during the COVID-19 pandemic can help managers in planning to improve and promote women's mental health, especially in critical situations.

Maternal serum adiponectin and leptin levels and their gene expression, postpartum body mass index, and breastfeeding duration based on mode of delivery: A prospective study.

BACKGROUND: Adipokines are involved in inflammatory responses, associated with body mass index whose concentrations may change in response to inflammatory conditions, including surgery and delivery. We examined adiponectin and leptin levels and their gene expression at birth, body mass index, and breastfeeding duration at 24 months postpartum according to mode of delivery. METHODS: In this study, 90 normal pregnant women were investigated. Blood samples were collected after delivery. Serum levels and gene expression of adiponectin and leptin were evaluated. Body mass index and breastfeeding duration were calculated at 24 months postpartum. Data were analyzed using SPSS-16 and p < 0.05 was considered as significant. RESULTS: Serum leptin level was significantly higher in vaginal delivery than in cesarean section (p = 0.033). No significant difference was found between two groups regarding adiponectin level and gene expression, while leptin gene expression was significantly higher in cesarean (p = 0.005). Postpartum body mass index did not differ between the two groups (p = 0.14). On the other hand, postpartum body mass index was significantly higher than the equivalent prepregnancy index in both groups (p < 0.001) and was associated with serum leptin and adiponectin in vaginal delivery (r = 0.46, p = 0.001, and r = -0.3, p = 0.04, respectively). The duration of breastfeeding was longer in vaginal delivery (p = 0.008). CONCLUSION: Cesarean section was associated with lower maternal leptin levels and shorter breast-feeding duration compared to vaginal delivery. Leptin gene expression was significantly higher in cesarean section than in vaginal delivery. Postpartum body mass index, adiponectin level, and gene expression did not differ between the two groups.

Evaluation of Couple's Sexual Function after Childbirth with the Biopsychosocial Model: A Systematic Review of Systematic Reviews and Meta-Analysis.

BACKGROUND: After childbirth, sexual dysfunction refers to a chain of psychiatric, physiological, social changes and a couple's experiences. The purpose of our Systematic Review (Syst.Rev.) is to evaluate available high-quality evidence and construct a Bio Psycho Social (BPS) model of couple's sexual function after childbirth. MATERIALS AND METHODS: A systematic search was done with MeSH terms in databases, including PubMed, Web of Science, Scopus, and Science direct. A total number of 9 Syst.Rev. were evaluated from 2009 to 2019 years. The quality of extracted articles was evaluated based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist of contents using two qualified reviewers. Data synthesis was performed using the thematic analysis. RESULTS: Biopsychosocial Model of Postpartum Couple's Sexual Function (BMPCSF) is proposed as a developmental process similar to Bronfenbrenner's Bioecological Systems Model. Studies showed a significant relationship among the type of childbirth, trauma of perineum, breastfeeding, mood swings, fears, changes in the self-body image, spousal support, and Postpartum Sexual Dysfunction (PSD). Hence, the evidence about male sexuality in the postpartum period doesn't seem sufficient. CONCLUSIONS: The information from this study will help health policymakers develop the appropriate guidelines to inform couples and healthcare professionals about the BPS changes after childbirth and PSD. Besides, BMPCSF can be used in postpartum sexual counseling to improve sexual health and marital relationships. We propose comprehensive original study on couples' postpartum sexuality, especially men's conduct, emphasizing socio-cultural factors.

Predicting the Relation between Biopsychosocial Factors and Type of Childbirth using the Decision Tree Method: A Cohort Study.

Background: With the growing rate of cesarean sections, rising morbidity and mortality thereafter is an important health issue. Predictive models can identify individuals with a higher probability of cesarean section, and help them make better decisions. This study aimed to investigate the biopsychosocial factors associated with the method of childbirth and designed a predictive model using the decision tree C4.5 algorithm. Methods: In this cohort study, the sample included 170 pregnant women in the third trimester of pregnancy referring to Shahroud Health Care Centers (Semnan, Iran), from 2018 to 2019. Blood samples were taken from mothers to measure the estrogen hormone at baseline. Birth information was recorded at the follow-up time per 30-42 days postpartum. Chi square, independent samples t test, and Mann-Whitney were used for comparisons between the two groups. Modeling was performed with the help of MATLAB software and C4.5 decision tree algorithm using input variables and target variable (childbirth method). The data were divided into training and testing datasets using the 70-30% method. In both stages, sensitivity, specificity, and accuracy were evaluated by the decision tree algorithm. Results: Previous method of childbirth, maternal body mass index at childbirth, maternal age, and estrogen were the most significant factors predicting the childbirth method. The decision tree model's sensitivity, specificity, and accuracy were 85.48%, 94.34%, and 89.57% in the training stage, and 82.35%, 83.87%, and 83.33% in the testing stage, respectively. Conclusion: The decision tree model was designed with high accuracy successfully predicted the method of childbirth. By recognizing the contributing factors, policymakers can take preventive action.It should be noted that this article was published in preprint form on the website of research square (https://www.researchsquare.com/article/rs-34770/v1).

Effect of turmeric on adiponectin, sexual function and sexual hormones in stressed mice.

Sexual function is essential for species survival. Melanocortin, progesterone, and estrogen can improve sexual function and they are modulated by adiponectin hormone which can be increased by Turmeric. In various studies shows Turmeric ability that is easily accessible to increase serum adiponectin levels. Therefore, the researchers decided to conduct a study to determine the effect of turmeric on serum adiponectin levels, sexual behavior, and profile of steroid hormones in stressed mice. Thirty female mice, six in each group (1. control group, 2. mice that received stress, 3. stress mice received 100 mg/kg turmeric (extract daily) for 4 weeks, 4. stress mice received turmeric (extract daily) for 4 weeks and also received adiponectin antagonist, and 5. stress groups received adiponectin antagonist), were used in the current study. The mice first underwent blood sampling. Then all mice were subjected to stress testing before the intervention except one group, which considered as a control group. The intervention in this study was done as a 100 mg/kg turmeric extract that was gavaged daily for each mouse. After the intervention, all mice were tested for sexual behavior, and then blood samples were taken to check serum levels of adiponectin, estradiol, progesterone and prolactin. So, the results showed before the intervention there were no significant difference among 5 group in levels of adiponectin (p = 0.145), estradiol (p = 0.148), progesterone (p = 0.166) and prolactin (p = 0.206) but after intervention there were significant difference between 5 group in levels of adiponectin, estradiol and progesterone (p < 0.001). Also there was significant difference among 5 groups in sexual behavior (p < 0.001). Therefore, consumption of turmeric, which increases serum adiponectin in the stressed mice, can improve sexual function and estradiol hormones profiling.

The influence of mode of delivery, anthropometric indices, and infant's sex on the maternal and cord blood orexin-A levels: A cohort study.

BACKGROUND: Orexin as an adipokin hormone plays an important role in appetite regulation, energy metabolism, obesity, diabetes, and cardiovascular disease. The main source of orexin secretion in nonpregnant and pregnant women is adipose tissue and placenta, respectively. This research was conducted to evaluate the association between orexin-A level and the mode of delivery, anthropometric indices, and sex of the infant. METHODS: This prospective cohort study was conducted on 69 normal pregnant women. The samples of umbilical cord blood were obtained at the time of delivery, and maternal blood was taken within 24 h of delivery. Serum orexin-A levels were measured by using enzyme-linked immunosorbent assay. Statistical analyses were performed using SPSS and p < 0.05 was considered as significant. RESULTS: We found a significant difference between postpartum maternal and umbilical cord orexin-A level both with the mode of delivery (p < 0.001). Also, a significant positive correlation was seen between maternal and umbilical cord serum orexin-A levels (r = -0.61, p < 0.001). There was no relationship between serum orexin-A levels with anthropometric indices and the sex of the neonate (p > 0.05). CONCLUSION: Both maternal and umbilical cord serum orexin-A levels were associated with the mode of delivery. Maternal and cord blood orexin-A levels in normal vaginal delivery are higher than cesarean section.

Maternal omentin-1 level, quality of life and marital satisfaction in relation to mode of delivery: a prospective cohort study.

BACKGROUND: The purpose of this study was to evaluate the maternal omentin-1 level, quality of life and marital satisfaction of women with cesarean and vaginal delivery. METHODS: This prospective cohort study was conducted on 45 women with elective cesarean delivery and 45 women with vaginal delivery who referred to a public hospital in Tehran, Iran. Maternal omentin-1 level was measured by ELISA kits within 24 h after delivery. The maternal quality of life and marital satisfaction in the third trimester of pregnancy and at 12 weeks postpartum were measured using WHOQOL-BREF and the Kansas marital satisfaction questionnaires, respectively. For making between-groups and within-groups comparison, independent samples t-test, paired samples t-test and chi-square test were applied accordingly. RESULTS: The level of maternal omentin-1 was reported to be higher in vaginal delivery group compared to the cesarean group (p = 0.02). No significant difference was found in the quality of life between the two groups in the third trimester of pregnancy and at 12 weeks postpartum period. However, women in both groups had lower scores in physical dimension at 12 weeks postpartum compared to the third trimester of their pregnancy [mean ± SD in vaginal group = 59.28 ± 15.5 vs. 64.44 ± 15.05, p = 0.003 and mean ± SD in cesarean group = 60.07 ± 14.84 vs. 66.50 ± 11.32, p <  0.001]. The results of paired samples t-test indicated that women in NVD group had significantly higher psychological wellbeing at 12 weeks postpartum compared to the third trimester of pregnancy [mean ± SD 68.9 ± 16.82 vs. 65.73 ± 16.87, p = 0.001]. There was no significant difference in marital satisfaction between the two groups at 12 weeks postpartum (P = 0.07). The results of paired samples t-test showed that women in CS group had significantly lower marital satisfaction at 12 weeks postpartum compared to the third trimester of pregnancy [mean SD 18.86 ± 2.04 vs. 19.28 ± 1.79, p = 0.01]. CONCLUSIONS: Our findings demonstrated that women with NVD had higher omentin-1 level than women with CS. No significant difference was found in quality of life and marital satisfaction between NVD and CS and omentin-1 level. High level of omentin-1 in NVD may act as a protective factor for mother against metabolic disorders.

Childbearing Intention and its Associated Factors among Adolescent Girls: A Narrative Review.

BACKGROUND: Childbearing is an important phenomenon among adolescents. Studies that have evaluated teenagers' reproductive patterns have found that many adolescents are ambivalent regarding sexual activity and childbearing. In order to assess the patterns of adolescents' reproductive health and pregnancy to conduct interventions, every country needs to collect specific data about childbearing intentions. This study was conducted to determine the factors that may affect the childbearing intentions of adolescents. MATERIALS AND METHODS: This article was a narrative review. Articles derived from PubMed, Scopus, and Web of Science from January of 2000 to February 2015 were assessed. Moreover, gray literature, such as conference abstracts, theses, and the result of technical reports were also used. RESULTS: In total, 15 studies were included in the review. The findings of this study showed that childbearing motives are affected by several factors. According to the results of the qualitative studies, some of the most important effective factors were women's decision-making power and financial issues. In this regard, the quantitative studies noted that the cultural and economic factors were more effective than other factors in determining the childbearing motives of adolescents. CONCLUSIONS: Fertility expectations are affected by several factors and are compatible with a variety of conditions. Moreover, access to precise information on the effects of each factor (positive or negative) is necessary and useful for demographers, policymakers, and other planners in any community.

Adiponectin levels in maternal serum and umbilical cord blood at birth by mode of delivery: relationship to anthropometric measurements and fetal sex.

BACKGROUND: The rate of cesarean section is increasing worldwide. Adiponectin is a hormone related to anti-inflammatory and anti-atherogenic effects; and it's concentrations may change in response to inflammatory situations including surgical intervention. The aim of the current study was to investigate serum adiponectin levels in maternal and umbilical cord blood according to different modes of delivery and their relationship with anthropometric measurements and fetal sex. METHODS: The study population initially comprised 90 healthy pregnant women referred to the teaching hospital. Eventually, 40 participants in the vaginal delivery group and 35 subjects in the cesarean delivery group were recruited in to the study. Umbilical cord blood and maternal serum samples were analyzed according to the standard protocol from the manufacturer. The collected data were analyzed using SPSS-16 software. P-value < 0.05 was considered as the significance level for all tests. RESULTS: Our results indicated a significant association between maternal adiponectin and the mode of delivery, with adiponectin levels significantly higher in vaginal delivery compared to cesarean section (P < 0.001). However, no difference was found in umbilical cord blood adiponectin between the two groups (P = 0.51). A significant positive correlation was found between maternal serum adiponectin in the first day after birth and umbilical cord blood adiponectin in the vaginal delivery group (P = 0.007). Nevertheless, this correlation was not statistically significant in the cesarean delivery group (P = 0.62). There was also no significant correlation between fetal sex and anthropometric measurements with maternal adiponectin (P = 0.44) and umbilical cord blood adiponectin (P = 0.86). CONCLUSIONS: The result of the current study revealed that maternal adiponectin concentration was significantly higher in vaginal delivery compared to cesarean section, which might be due to the increased levels of maternal adiponectin release during labor.

The Postpartum Marital Satisfaction, Maternal Serum Concentration of Orexin-A and Mode of Delivery.

Aims: We aimed to assess the association of postpartum maternal serum concentration of orexin-A with postpartum marital satisfaction considering the effect of mode of delivery as an influential factor. Methods: This cohort study conducted among third trimester pregnant women, who met our eligibility criteria. Postpartum maternal and cord serum concentration of orexin-A were measured and their association with postpartum marital satisfaction were assessed considering the impact of mode of delivery. Results: There was a statistically significant positive association between postpartum maternal and cord serum levels of orexin-A (r = 0.79, p < 0.001) and postpartum marital satisfaction among women with cesarean section (r = 0.31, p < 0.01). The maternal orexin-A level of women delivered with cesarean section who had post-partum marital dissatisfaction was significantly lower than those one with marital satisfaction (84.13 ± 95.88 vs. 153.08 ± 95.88 pg/ml, p = 0.04). Logistic regression model showed that the type of delivery was not related to marital satisfaction (OR = 1.7, 95%CI: 0.6, 4.8), p = 0.280). Conclusions: The postpartum maternal serum orexin-A level was associated with marital satisfaction in women delivered through cesarean section.

School girls and childbearing motives: A randomized clinical trial through hidden curriculum.

BACKGROUND: Childbearing motives are considered as the primary stimulus of fertility and the importance of making fertility decisions in humans. OBJECTIVE: The aim of this study is to determine the effect of a new form of interactional program on the childbearing motives of students. MATERIALS AND METHODS: According to a well-defined, single-blind randomized controlled trial, we selected eight government schools in Tehran. Students in the age range of 7-12 yr and 16-18 yr (130 students in each school with a total number of 260) were selected for a series of intervention from storytelling to free discussion on a special subject through the concept of hidden curriculum. We evaluate the outcome with pretest-posttest based on the Miller childbearing motives questionnaire. One month after the last intervention, final evaluation took place. RESULTS: The findings showed that after an intervention conducted in the best way, all positive scores were promoted while the negative ones declined. One the other hand, no matter what really the participant's groups were, their total intention score got better. In this way, the total positive scores were significantly increased in the intervention groups (p = 0.000) Also, the students in high school significantly improved in positive scores and the negative score decreased in them. CONCLUSION: This study showed that the fundamental childbearing motives even with small interventions can be improved. Our intervention could improve the positive childbearing motives among school girls. In this regard, the role of some confounding factor such as the role of some confounding factors such as religious beliefs in family, maternal education is most important.

Visfatin as a predictor for growth of fetus and infant.

OBJECTIVE: Visfatin is an adipocytokine that functions as an enzyme and a growth factor to investigate the relationship between serum visfatin and the fetus's anthropometric markers up to a year after birth. MATERIALS AND METHODS: Forty-one eligible pregnant women in their first trimester were divided and matched in terms of body mass index (BMI) before pregnancy into normal and higher than normal BMI groups, A and B. Serum visfatin levels were measured during 6-12 and 15-20 weeks of gestation using ELISA. RESULTS: The infants were followed up for a mean duration of 10.19±2.83 months. In group A, there was a strong positive relationship between birth head circumference and the first (p1=0.054, r1=0.580) and second trimester visfatin levels (p2=0.051, r2=0.530). In group B, second trimester visfatin levels correlated negatively with birth length (p=0.015, r=-0.523) and infant's head circumference (p2=0.050, r2=-0.392). In a separate study on group B, visfatin levels in the first and second trimesters showed a significant negative correlation with infant's weight. A significant correlation was observed between the first and second trimesters visfatin level with infant's height in both groups, such that this relationship was positive in group A and negative in group B. Linear regression analysis revealed that first and second trimester visfatin levels were significant independent predictors of infant's weight in group B and infant's height in both groups. Second trimester visfatin level was a significant predictor of birth height in group B. CONCLUSION: Maternal serum visfatin level shows a relationship with fetal and infant anthropometric indicators, with different effects in the two groups, suggesting visfatin dysfunction in the overweight group before pregnancy.

Clinical diagnosis of pelvic endometriosis: a scoping review.

BACKGROUND: Accurate and timely diagnosis of endometriosis is associated with confusion. Clinical manifestations, imaging techniques, biomarkers and surgical techniques are used as diagnostic approaches. This paper reviews current evidence on clinical manifestation in order to help practitioners and perhaps improve women's health. METHODS: A review of the literature on clinical diagnosis of pelvic endometriosis that appeared in the English language biomedical journals was performed using PubMed, Science Direct and Google Scholar. The search strategy included the combination of key words 'endometriosis' and 'diagnosis' or 'clinical diagnosis' in the titles or abstracts of articles. The search included all papers published during the year 2000 to 2014. Then, the findings were classified in order to summarize the evidence. RESULTS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, in all 51 papers were found relevant and included in this review. In general we found three categories of diagnostic approaches for clinical manifestation including: i) diagnosis via symptoms obtained from history taking, ii) diagnosis via signs obtained from physical examination and iii) diagnosis via risk factors obtained from history taking. CONCLUSION: Diagnosis of endometriosis is a matter of concern. Since the disease is associated with diverse clinical symptoms and signs, deeper and more comprehensive consideration according to patient's history and clinical findings is recommended for early and more accurate detection in order to prioritize women for further investigation and contribute to its early management.

Antioxidants and management of polycystic ovary syndrome in Iran: A systematic review of clinical trials.

BACKGROUND: Recently there is a focus on the antioxidants as adjuvant treatment of polycystic ovary syndrome (PCOS), the most endocrinopathy in reproductive age women. OBJECTIVE: The aim of this review is answer to the question whether antioxidants are effective for managing of hormonal and metabolic problems in women with PCOS based on first degree evidences from Iran. MATERIALS AND METHODS: A systematic review of clinical trials was done in Persian and international databases including PubMed, Scientific Information Database, Google Scholar, Iran Medex, and Magiran up to 2013. Keywords were including polycystic ovary syndrome, Iran, vitamin, antioxidant. From 440 potential studies found electronically, 11 studies; including 444 women in intervention and 390 women in control groups. Intervention in three studies was Calcium-vitamin D or calcitriol; in three studies was ω-3 fatty acids; in two studies was N-acetyl cysteine; in one study was folic acid; in one study was Zinc; and in one study was Soy. RESULTS: Finally, 11 studies that were relevant and met the inclusion criteria reviewed. There were 7 studies in English and 4 studies in Persian. We couldn't include all studies because all full texts were not accessible. CONCLUSION: The results showed that antioxidants and vitamins have positive effects on management of PCOS women. Although it seems more studies is necessary in this field.

Trend of ectopic pregnancy and its main determinants in Hamadan province, Iran (2000-2010).

BACKGROUND: Ectopic pregnancy remains a major gynaecologyical problem in contemporary gynaecological practice. The purpose of this study was to determine the incidence and some risk factors of ectopic pregnancy in Hamadan province during 2000-2010. METHODS: This was a retrospective descriptive study carried out at hospitals in Hamadan provience, Iran. A total of 872 women with the diagnosis of ectopic pregnancy between 2000 to 2010 were recruited. At initial assessment, 872 medical records were targeted for the assessment, while because of incompleteness of some recorded information, 521 files were finally assessed. RESULTS: The overall incidence of ectopic pregnancy was estimated to be 2.6 per 1000 recorded pregnancies. While, considerably increased from 1.5 per 1000 pregnancy in 2000 to 4.8 per 1000 pregnancies in 2010. More than half of the women aged 25 to 34 years. 48.2% of selected women were using contraception methods. 5.2%, 14.0% and 5.6% of women had pervious ectopic pregnancy, first or second infertility and pelvic inflammatory diseases, respectively. CONCLUSION: Increasing trend of the incidence of ectopic pregnancy is expected due to development and availability of minute diagnostic approaches and also some baseline amendable (contraceptive methods and surgical interventions) and unchangeable (age of pregnancy and residency) parameters.

Patients' and physicians' descriptions of occurrence and diagnosis of endometriosis: a qualitative study from Iran.

BACKGROUND: The prevalence of endometriosis is considerable but its diagnosis is a dilemma. The aim of this study was to explore the perception and experiences of endometriosis patients and physicians about occurrence and diagnosis of endometriosis. METHODS: A qualitative research using content analysis was used to obtain data from purposely selected endometriosis patients (12 participants) and gynecologists (6 participants) from January to September 2013 in Tehran. Data were coded and analyzed using a thematic approach. RESULTS: Seven themes emerged: 1) pain localization, 2) Severity of pain and struggle for pain relief, 3) Feeling inability to play the role of femininity, 4) Reducing physical health, 5) Disruption of social life, 6) Looking for a reliable diagnostic indicator, 7) Uncertainty of physical examination. The results highlighted that patients with the disease can experience different feelings that interfere with their wellbeing and their lives, and sometimes could be disabling. CONCLUSION: Patients and physicians are looking for a certain, noninvasive and inexpensive diagnostic method. This study helps to promote clinical diagnostic view and knowledge development about description of endometriosis diagnosis to decrease diagnostic delay and mismanagement.

Combination effect of PectaSol and Doxorubicin on viability, cell cycle arrest and apoptosis in DU-145 and LNCaP prostate cancer cell lines.

The effect of PectaSol on Dox (Doxorubicin) cytotoxicity in terms of apoptosis and cell cycle changes in PCa (prostate cancer) cell lines (DU-145 and LNCaP) has been investigated. Combination of PectaSol and Dox resulted in a viability of 29.4 and 32.6% (P<0.001) in DU-145 and LNCaP cells. The IC50 values decreased 1.5-fold and 1.3-fold in the DU-145 and LNCaP cells respectively. In the DU-145 cells, combination of PectaSol and Dox resulted in a reduction in p27 gene and protein expression (P<0.001). In LNCaP cells, this combination increased p53, p27 and Bcl-2 expression. Treatment with both drugs in DU-145 cells led to an increase in sub-G1 arrest (54.6% compared with 12.2% in Dox). In LNCaP cells, combination of the drugs led to an increased in G2/M arrest (61.7% compared with 53.6% in Dox). Based on these findings, progressive cytotoxicity effect of Dox and PectaSol together rapidly induce cell death in DU-145 through apoptosis and in LNCaP cells through cell cycle arrest (G2/M arrest).
