The present study was conducted to investigate the oxidant–antioxidant status in iron deficient pregnant anemic women. One
hundred thirty pregnant women with iron deficiency anemia (IDA) were divided into three groups, namely mild (50), moderate
(50) and severe (30) anemic along with pregnant healthy women as controls (50). The complete blood count, plasma lipid peroxidation
products, enzymatic and non-enzymatic antioxidants were measured according to respective protocols. The levels of complete
blood count, iron, ferritin along with antioxidant enzymes namely catalase, superoxide dismutase, glutathione peroxidase,
glutathione reductase and reduced glutathione were significantly reduced in all IDA groups. However, the level of oxidized
glutathione, lipid peroxides, protein carbonyls, conjugated dienes were found significantly increased in all anemic patients.
Antioxidant vitamins, namely C, E and A were also found significantly decreased in IDA patients. On the basis of our results,
it may be concluded that IDA tends to increase the pro-oxidant components, which may result in various complications including
peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus. 相似文献

Familial hypercholesterolemia (FH) is an autosomal dominant disorder of lipoprotein metabolism caused mainly by mutations
in the low-density lipoprotein receptor (LDLR) and apolipoprotein B 100 (APOB) genes. Until now, the molecular basis of FH
has been demonstrated in detail in many populations, but there is still very limited Molecular data concerning FH in Iran.
The aim of this study was to characterize the LDLR and APOB gene mutations in an Iranian population. A total of 30 non-related
Iranian possible FH subjects were studied. Diagnosis of FH was based on the Dutch Lipid Clinic Network diagnostic criteria.
All samples were initially tested for three common APOB gene mutations including R3500Q, R3500 W and R3531C using PCR-RFLP
assay. Subsequently, promoter and coding region of the LDLR gene was screened by PCR-SSCP analysis and positive results were
confirmed by DNA sequencing. Four previously reported polymorphisms 1413G > A, 1725C > T, 1773T > C and 2140 + 5G > A were
found in ~17% (5/30) of population studied. Moreover, no variation was found in APOB gene. Our data indicated that LDLR and
APOB gene mutations have not contribution to possible FH in Iranian population studied here. However, we examined three common
APOB mutations and LDLR in only 30 patients, and to determine the role of these genes in developing FH in Iran, more FH samples
and populations needed to be investigated for the mutations of the related genes. 相似文献

研究目的:基于过程分析技术框架,优化家禽业的废水处理工艺的性能。研究方法:生产商主要关注浊度和污泥容积指数(SVI)这两个响应。首先为每个响应建立移动平均(MA)和移动范围(MR)控制图,并在实验工作中重复两次33全因子设计。基于模糊目标规划建立加权相加模型,并用于确定最佳的因子设置组合。最后,在最佳的因子设置组合条件下,对实验结果进行跟踪确认。重要结论:在絮凝剂为18 mg/L、凝结剂为40.0 mg/L和p H=4.0的最佳工艺条件下,得到的浊度和污泥体积指数的最佳值分别为6.184 NTU和73.21 ml/g。在此条件下得到的浊度和污泥沉降指数能够满足设计要求,它们的过程变异性分别显著下降了41.22%和77.75%,且多重能力指数从1.95显著增加至10.6。这表明此过程可行性很高。总之,加权相加模型是一种用于优化多个响应流程性能的有效技术,并且可以考虑工程师的首选设置流程。 相似文献

Most people in Bangladesh are rural, poor and underprivileged. The incidence of sexual disease has increased, but little has been done to educate rural people about sexual and reproductive health. In 1997, a sexual and reproductive health project was initiated within a collaborative research agreement between the International Centre for Diarrhoeal Disease Research (ICDDR,B) and the Bangladesh Rural Advancement Committee (BRAC), an indigenous non-governmental organization which pursues integrated rural development strategies. Qualitative in-depth interviews with 65 different women, men, boys and girls revealed significant sexual health problems and a lack of knowledge of sexual and reproductive health. The interviews were transformed into composite problem-solving picture stories and information about sexual and reproductive health. Stories mirrored respondents' interpretations of sexual behavior. Those who had achieved or ascribed legitimacy to talk about sex, e.g. traditional health providers, were trained to utilize the methods and materials. Qualitative evaluations revealed important changes in health providers' self-confidence, business and personal interactions as well as changes in clients' behavior. This project found that sexual and reproductive health education can be integrated into indigenous health activities if the sociocultural context in which sex, relationships, risks, diseases and communication occur is reflected in a program's content and methods. Unquestionably, there is a great need for sex education in rural Bangladesh. 相似文献

AbstractThis essay explores the issue of dress of teachers of Druze heritage. The Druze, among whom the rules of religious dress are rather specific, do not teach religion in schools, since the Druze religion is secret. The teacher acts as a gatekeeper and model. At the same time, Druze young people are becoming increasingly secular and may relate better to teachers who appear to be part of the modern world. This discussion examines the role of dress in teacher modeling, and the part Druze teachers may have to play in sustaining a small religion in rapidly changing times. 相似文献

This paper presents the development of an Argument-Learning System （ALES）. The idea is based on the AIF （argumentation interchange format） ontology using ＂Walton theory＂. ALES uses different mining techniques to manage a highly structured arguments repository. This repository was designed, developed and implemented by the authors. The aim is to extend the previous framework proposed by developing an intelligent tutoring environment for argument learning that aims to： （1） guide the students during argument learning; （2） aid in improving the students＇ argument skills; and （3） offer an argument classifier agent that retrieves the most relevant results to the subject of search. This paper focuses on the environment development specifying the status of each of the constituent modules. 相似文献

The management of intellectual capital (IC) resources increases organizational value creation capacities. The aim of this study is to present an algorithm for analysing IC management with an emphasis on the recognition and modelling of growth mechanisms for strategic resources. Intensive interactions among different tangible and intangible assets turn organizations into complex systems of highly interrelated resources; therefore, a systems approach is adopted, and a causal loop diagram is used to model resource interaction feedback structures. The development and analysis of the resource interactions model is explained through a practical algorithm that reveals different dimensions of resource deployment, including the potential value of resources, utilization of resources in key business processes, and mechanisms responsible for the sustained growth of strategic resources. The proposed algorithm was used to examine a telecommunication company. We show that there are no growth mechanisms for certain strategic resources. To activate the growth of such strategic resources, several feedback loops are recognized and related initiatives are proposed. 相似文献
