Primary ciliary dyskinesia (PCD) is a disorder of structure and function of motor ciliary and dyskinetic activity of ciliary in the fallopian tubes of affected women and could lead to infertility in some cases. In vitro fertilisation (IVF) is a choice of treatment in infertile women with PCD, which could conquer the tubal dysfunction. In this case study, we report a PCD affected woman with infertility who was treated by IVF and pregnancy was achieved but it failed due to the spontaneous abortion. We also performed whole-exome sequencing for this case and her PCD-affected sister, which did not reveal any genetic abnormality related to the PCD or infertility. 相似文献
Common carotid intima-media thickness (cIMT) is an index of subclinical atherosclerosis that is associated with ischemic stroke and coronary artery disease (CAD). We undertook a cross-sectional epigenome-wide association study (EWAS) of measures of cIMT in 6400 individuals. Mendelian randomization analysis was applied to investigate the potential causal role of DNA methylation in the link between atherosclerotic cardiovascular risk factors and cIMT or clinical cardiovascular disease. The CpG site cg05575921 was associated with cIMT (beta?=??0.0264, p value?=?3.5?×?10–8) in the discovery panel and was replicated in replication panel (beta?=??0.07, p value?=?0.005). This CpG is located at chr5:81649347 in the intron 3 of the aryl hydrocarbon receptor repressor gene (AHRR). Our results indicate that DNA methylation at cg05575921 might be in the pathway between smoking, cIMT and stroke. Moreover, in a region-based analysis, 34 differentially methylated regions (DMRs) were identified of which a DMR upstream of ALOX12 showed the strongest association with cIMT (p value?=?1.4?×?10–13). In conclusion, our study suggests that DNA methylation may play a role in the link between cardiovascular risk factors, cIMT and clinical cardiovascular disease.
Background: Tobacco use is a significant predisposing factor to many diseases. Protection motivation theory is a well-suited theory, since fear can motivate individuals to change their unhealthy behaviors. Objective: This study was conducted to examine the associations between the constructs of this theory with intention and tobacco use behavior. Method: The present cross-sectional study was conducted in Noshahr, Iran. The participants were 440 high school boys selected using a stratified random sampling in 2016. A questionnaire about tobacco use based on protection motivation theory was developed and its validity and reliability were assessed. The questionnaire included the demographic information, the constructs of theory, and tobacco use behavior. Structural equation modeling was used to test the associations between the constructs with intention and tobacco use. Results: The variables of perceived vulnerability (β = 0/137, P < 0.001), fear (β = 0/149, P < 0.001), self-efficacy (β = 0/249, P < 0.001), perceived intrinsic reward (β = ?0.285, P < 0.001), threat appraisal (β = ?0.25, P < 0.001), and coping appraisal (β = 0.358, P < 0.001) had direct effect and are significant with intention. Moreover, perceived vulnerability (β = ?0.158, P < 0.001), fear (β = ?0.172, P < 0.001), self-efficacy (β = ?0.288, P < 0.001), perceived intrinsic reward (β = 0.329, P < 0.001), threat appraisal (β = 0.265, P < 0.001), and coping appraisal (β = ?0.379, P < 0.001) affected tobacco use indirectly through intention and were significantly associated with behavior. Also, intention had direct effect and is significant with tobacco use (β = ?1.156, P < 0.001). Conclusions: The protection motivation theory provides a useful framework for investigating factors of tobacco use among male students. Future tobacco prevention interventions should focus on increasing the vulnerability and fear, decreasing intrinsic reward, and improving self-efficacy to reduce tobacco use. 相似文献
This paper provides significant ethnobotanical information on pharmaceutical plant uses, where some degree of acculturation exists, so that there is urgency in recording such data. The aim of this work is to catalogue, document, and make known the uses of plants for folk medicine in Dehloran and Abdanan districts, Ilam Province, Iran. An analysis was made of the species used, parts of the plant employed, preparation methods, administration means, and the ailments treated in relation to pathological groups. A folk botanical survey was carried out from February 2007 to October 2009. The information was collected from 81 persons (60% men and 40% women) in 20 villages. The informants reported data on 122 species, belonging to 49 botanical families, were claimed as medicinal. This work is focused on human medicinal plant uses, which represent 95% of the pharmaceutical uses. The most commonly represented families were Asteraceae (37.5%), Lamiaceae (20.8%), Rosaceae (18.7%), Fabaceae (16.7%) and Apiaceae (14.6%). Some of the uses were found to be new when compared with published literature on ethnomedicine of Iran. The folk knowledge about medicinal plant use is still alive in the studied region, and a number of scarcely reported plant uses has been detected, some of them with promising phytotherapeutical applications. The results of the study reveal that some of species play an important role in primary healthcare system of these tribal communities. 相似文献
Background: Sleep is one of the most basic human requirements. This research aims at determining the status of sleep quality and its relationship with quality of life among high-risk pregnant women in Tabriz, Iran, in 2015.Materials and methods: This research was a sectional study done on 364 qualified women in 28–36 weeks of pregnancy suffering from mild preeclampsia and gestational diabetes. The sampling was done as convenience. Personal–social–midwifery questionnaire, Pittsburg sleep quality, and quality of life in pregnancy (QOL-ORAV) were used for gathering data. Multivariate linear regression model was used for determining the relationship between sleep quality and its subsets with quality of life and controlling confounders.Findings: In the current study, the prevalence of sleep disturbance was 96.4%. Mean (SD) of the total score of sleep quality was 10.1 (4.1) and the total score of quality of life was 61.7 (17.3). According to Pearson’s correlation test, there was statistically significant relationship between quality of life and sleep quality and all its subsets except sleep duration and use of sleep medication (p?0.001). Meanwhile, according to the multivariate linear regression model, sleep latency, day time dysfunction, health status, and home air-conditioning were related with quality of life.Discussion: The findings of current research show that sleep quality is low among high-risk pregnant women and quality of life is medium. So, it is necessary that required training is given by health cares for improving sleep quality and quality of life to mothers. 相似文献
Non-medical approaches including cognitive behavioral therapy (CBT) have been proposed for the management of tocophobia. A new method of performing CBT is through internet. The aim of this systematic review and meta-analysis was to evaluate the effect of internet-based and traditional CBT on tocophobia. A literature search was conducted on qualitative and quantitative articles from 2000 to 2019 in Pubmed, Scopus, Web of Science and Cochrane databases using search terms referring to tocophobia and CBT. Identified articles were screened in two steps; 1) title and abstract and 2) full text screening. The quality of the quantitative and qualitative studies was assessed using the quality criteria proposed by the Cochrane Collaboration and Jonna Briggs Institute (JBI) checklist respectively. Out of the 382 relevant studies, 9 studies were eligible for the review. A high level of heterogeneity was observed in the studies (I2 = 94%, P < 0.001). The meta-analysis showed that both internet-based, and traditional CBT were effective in reducing tocophobia. CBT was more effective in interventions in the Middle Eastern compared to European countries. More than five CBT sessions could significantly reduce tocophobia. Healthcare providers and midwives should have basic knowledge on physiological interventions to reduce tocophobia. 相似文献
In this work we proposed a model for in vitro interaction of fenitrothion (FEN) with calf thymus-DNA by combination of multispectroscopic and two dimensional molecular modeling (ONIOM) methods. The circular dichroism results showed that FEN changes the conformation of B-DNA and caused some changes to C-DNA form. The FT-IR results confirmed a partial intercalation between FEN and edges of all base pairs. The competitive fluorescence, using methylene blue as fluorescence probe, in the presence of increasing amounts of FEN, revealed that FEN is able to release the non-intercalated methylene blue from the DNA. The weak chemical shift and peak broadening of 1H NMR spectrum of FEN in the presence of DNA confirmed a non-intercalation mode. The 31P NMR showed that FEN interacts more with DNA via its –NO2 moiety. The ONIOM, based on the hybridization of QM/MM (DFT, 6.31++G (d,p)/UFF) methodology, was also performed by Gaussian 2003 package. The results revealed that the interaction is base sequence dependent, and FEN interacts more with AT base sequences. 相似文献
ABSTRACTReadiness to care for family, infant, and self are important during the postpartum period. The objective of this study was to determine the relationships of self-efficacy and postpartum depressive symptoms with functional status in randomly sampled Iranian mothers (n = 437). The study was cross-sectional and conducted in 2015. The mean (SD) of the total functional status score was 2.3 (0.2) out of a possible score of 1–4. The maximum and minimum scores in infant care were 4.0 and 2.2 and, in social and community activity, levels were 3.5 and 1.0, respectively. Significant inverse correlations were observed between postpartum depressive symptoms and total scores for functional status, self-care, and levels of social and community activity. A significant positive relationship was observed between self-efficacy and functional status and all of its subscales. In the multivariate linear regression model, postpartum depressive symptoms, nulliparity, and low income were significantly negatively related with functional status; maternal self-efficacy, having a spouse aged 26–35 years, high school diploma, lower educational level, and the spouse’s job (shopkeeper) were significantly positively correlated with functional status. Early diagnosis and treatment of depressive symptoms and promotion of maternal self-efficacy may improve overall functional status of mothers in the postpartum. 相似文献
