1Gestational diabetes: A clinical update显示文摘Gestational diabetes mellitus(GDM)is increasing in prevalence in tandem with the dramatic increase inthe prevalence of overweight and obesity in women of childbearing age.Much controversy surrounds the diagnosis and management of gestational diabetes,emphasizing the importance and relevance of clarity and consensus.If newly proposed criteria are adopted universally a significantly growing number of women will be diagnosed as having GDM,implying new therapeutic challenges to avoid foetal and maternal complications related to the hyperglycemia of gestational diabetes.This review provides an overview of clinical issues related to GDM,including the challenges of screening and diagnosis,the pathophysiology behind GDM,the treatment and prevention of GDM and the long and short term consequences of gestational diabetes for both mother and offspring.Ulla Kampmann Lene Ring Madsen Gitte Oeskov Skajaa Ditte Smed Iversen Niels Moeller Per Ovesen 2015World Journal of Diabetes2015,6,8:17
2Fault diagnosis for distillation process based on CNN–DAE显示文摘Distillation is the most widely used operation for liquid mixture separation in the chemical industry. It is of great importance to detect and diagnose faults in distillation process. Due to the strong feedback and coupling of processes in a distillation column, it is difficult to use deep auto-encoders(DAEs) alone to achieve good results in detecting and diagnosing faults, in terms of accuracy and efficiency. This paper proposes a hybrid fault-diagnosis model based on convolutional neural networks(CNNs) and DAEs, by integrating the powerful capability of CNN in feature extraction and of DAE in classification. A case study was carried out with the distillation process of depropanization. It is shown that the proposed hybrid model is of good performance compared to other models, in terms of the accuracy of fault detection in such a process. Also, with the increase of structural layers of the CNN–DAE model, the diagnostic accuracy will be improved, with an optimal accuracy of 92.2%.Chuankun Li Dongfeng Zhao Shanjun Mu Weihua Zhang Ning Shi Lening Li 2019Chinese Journal of Chemical Engineering2019,27,3:12
3从丹麦牙科教育看我国口腔医学教育的发展显示文摘丹麦现行的口腔医学教育体系和模式特点体现在教师启发和动员学生主动思考的作用强 ,学生的参与性强 ,提问和辩论突出。另外学生早期接触临床实践 ,从第二年即开始临床见习 ,并随年级的增长逐步增加诊断、预防、治疗和定期口腔护理 ,最终独立接诊。各学科教学效果并非单纯考试决定 ,而是由包括学校行政、教师、学生代表等的专业委员会来综合评估 。王勤涛 张玉梅 Lene Rindal Nielsen 2003牙体牙髓牙周病学杂志2003,13,8:11

5Identification of abnormal conditions in high-dimensional chemical process based on feature selection and deep learning显示文摘Identification of abnormal conditions is essential in the chemical process.With the rapid development of artificial intelligence technology,deep learning has attracted a lot of attention as a promising fault identification method in chemical process recently.In the high-dimensional data identification using deep neural networks,problems such as insufficient data and missing data,measurement noise,redundant variables,and high coupling of data are often encountered.To tackle these problems,a feature based deep belief networks(DBN)method is proposed in this paper.First,a generative adversarial network(GAN)is used to reconstruct the random and non-random missing data of chemical process.Second,the feature variables are selected by Spearman’s rank correlation coefficient(SRCC)from high-dimensional data to eliminate the noise and redundant variables and,as a consequence,compress data dimension of chemical process.Finally,the feature filtered data is deeply abstracted,learned and tuned by DBN for multi-case fault identification.The application in the Tennessee Eastman(TE)process demonstrates the fast convergence and high accuracy of this proposal in identifying abnormal conditions for chemical process,compared with the traditional fault identification algorithms.Wende Tian Zijian Liu Lening Li Shifa Zhang Chuankun Li 2020Chinese Journal of Chemical Engineering2020,28,7:3
6Hepatitis C virus infection in the human immunodeficiency virus infected patient显示文摘Human immunodeficiency virus(HIV)and hepatitis C virus(HCV)share the same transmission routes;therefore,coinfection is frequent.An estimated 5-10 million individuals alone in the western world are infected with both viruses.The majority of people acquire HCV by injection drug use and,to a lesser extent,through blood transfusion and blood products.Recently,there has been an increase in HCV infections among men who have sex with men.In the context of effective antiretroviral treatment,liver-related deaths are now more common than Acquired Immune Deficiency Syndromerelated deaths among HIV-HCV coinfected individuals.Morbidity and mortality rates from chronic HCV infection will increase because the infection incidence peaked in the mid-1980s and because liver disease progresses slowly and is clinically silent to cirrhosis and end-stage-liver disease over a 15-20 year time period for 15%-20%of chronically infected individuals.HCV treatment has rapidly changed with the development of new direct-acting antiviral agents;therefore,cure rates have greatly improved because the new treatment regimens target different parts of the HCV life cycle.In this review,we focus on the epidemiology,diagnosis and the natural course of HCV as well as current and future strategies for HCV therapy in the context of HIV-HCV coinfection in the western world.Louise Nygaard Clausen Lene Fogt Lundbo Thomas Benfield 2014World Journal of Gastroenterology2014,20,34:3
7Evaluation of a new qPCR test to identify the organisms causing high total bacterial count in bulk tank milk显示文摘Milk quality in bulk tank milk(BTM)is measured by flow cytometry technology as total bacterial count(TBC)and somatic cell count(SCC).To investigate SCC problems,culture or PCR can be used to identify mastitis causing bacteria,e.g.,Mastit 4,a commercially available qPCR test.TBC in BTM can be investigated further using culture-based methods such as standard plate count,laboratory pasteurization count,coliform count,and spore counts.To our knowledge,no qPCR addressing the bacteria involved in TBC has been commercially introduced.The aim of this study is to evaluate a recently introduced 3-h qPCR test,TBC 4.The TBC 4 qPCR detects four target groups,Pseudomonas,Streptococci,Enterobacteriacea/Enterococcus,and Bacillus/Clostridia.These target groups relate to problems on the farm such as cooling,mastitis,environment,and silage.We will continue with new research to compare the TBC 4 qPCR test with traditional culture.For this study,BTM samples from different TBC intervals were selected based on Bacto Count results found at routine payment investigation at Eurofins laboratory(Vejen,Denmark).These samples were analyzed using TBC 4 qPCR assay within 24 h.In total,346 BTM samples were divided into six different intervals of colony forming units(CFU).For all four targets in each of the different intervals of CFU,the percent of positive samples,the average C_t-value,the percent of positive samples with C_t<30 and C_t<25 were calculated.For Pseudomonas,Streptococci,and Enterobacteriacea/Enterococcus,the number of positive samples with lower C_t-values(high bacteria content)correlated with the CFU mL^(–1).We found Enterobacteriacea/Enterococcus,Pseudomonas,and Streptococci in high number of bacteria(C_t<25)in 25,19 and 56%of samples with CFU mL^(–1) between 50 001–100 000 and 53,44,and 39%in samples with CFU mL^(–1)>100 000.The TBC 4 qPCR test showed to be a strong and fast tool for farmers,advisors and service technicians to address problems with high TBC and ensuring the delivery of good quality milk to the dairy.Jorgen Katholm Lene Trier Olesen Anders Petersen Snorri Sigurdsson 2018Journal of Integrative Agriculture2018,17,6:3
