The disease types, symptom characteristics, pathogenesis and ecological control technology of hedgerow commonly used in landscape greening in Nanjing, Zhenjiang, Changzhou, Wuxi and Suzhou were systematically studied. The results showed that there were 10 kinds of common diseases of flowers and shrubs in landscape greening in five cities of southern Jiangsu. Among them, 8 were caused by deuteromycotina and 2 were caused by subphylum basidiomycetes. It was pointed out that the disease regularity was directly related to the pathogenic bacteria, temperature and humidity, microclimate and hedgerow growth. For the first time, the ecological control method of hedgerow disease which focused on ecological health maintenance was put forward. 展开更多

[ Objective ] The research aimed to discuss the occurrence regularity of apple early defoliation disease and control effects of fungicides in west Sichuan plateau. [ Method ] Apple early defoliation disease in west Sichuan plateau was systematically investigated during 2009 and 2011, and the control effects of different fungicides during different spraying periods were studied. [ Result] The species of pathogen mainly was Marssonina ma/i ( P. Henn), accounting for 32.5%, Phyl-losticta Pirina Sa accounted for 29.9%, and Alternaria mali Roberts accounted for 25.7%. The field fluctuation regularity was as follows : the disease generally be- gan in the mid-May and ended in early and middle October with only one damage peak during the whole year, the fluctuation had positive correlation with rainfall ( R2 =0.891 8 * * ). Control test showed that 40% flusilazole had the best control effect (86.5%), which was best to apply after anthesis. [ Conclusion ] The paper provided theoretical basis for the effective control against apple early defoliation disease. 展开更多

Alzheimer’s disease (AD) is an increasingly pressing worldwide public-health, social, political and economic concern. Despite significant investment in multiple traditional therapeutic strategies that have achieved success in preclinical models addressing the pathological hallmarks of the disease, these efforts have not translated into any effective disease-modifying therapies. This could be because interventions are being tested too late in the disease process. While existing therapies provide symptomatic and clinical benefit, they do not fully address the molecular abnormalities that occur in AD neurons. The pathophysiology of AD is complex; mitochondrial bioenergetic deficits and brain hypometabolism coupled with increased mitochondrial oxidative stress are antecedent and potentially play a causal role in the disease pathogenesis. Dysfunctional mitochondria accumulate from the combination of impaired mitophagy, which can also induce injurious inflammatory responses, and inadequate neuronal mitochondrial biogenesis. Altering the metabolic capacity of the brain by modulating/potentiating its mitochondrial bioenergetics may be a strategy for disease prevention and treatment. We present insights into the mechanisms of mitochondrial dysfunction in AD brain as well as an overview of emerging treatments with the potential to prevent, delay or reverse the neurodegenerative process by targeting mitochondria. 展开更多

[ Objective] The paper was to understand species of diseases, pests and weeds and their occurrence periods and dynamic changes of quantity during corn growing period in rainy and dry seasons in Angola. [ Method] Using systematic investigation method, the species and occurrence regularity of diseases, pests and weeds of corn in Pedras Negras farm ( Malanje), Sanza Pombo farm (Uige) and Catete farm (Luanda) in the Mrican continent, the Republic of Angola, were studied in two dry seasons and a rainy season from 2011 to 2012. [ Result] The occurrence status of pests and diseases of corn during dry and rainy seasons were basically similar, and only individual diseases and pests had different incidence degrees. The corn varieties from the United States and Brazil had prominent advan- tages in resistance to diseases and barren. Due to different climate environments in dry and rainy seasons, the unearthed rate of weeds in fields was also different. Soil moisture had great impact on weed population and density. Soil layer depth greatly influenced unearthed speed and unearthed rate of weeds. [ Conclusion ] The study cleared species, occurrence period and harmful levels of pests, diseases and weeds of corn in three provinces of Angola. 展开更多

The molecular scalpel of clustered regularly interspersed short palindromic repeats/CRISPR associated protein 9(CRISPR/Cas9) technology may be sharp enough to begin cutting the genes implicated in inflammatory bowel disease(IBD) and consequently decrease the 6.3 billion dollar annual financial healthcare burden in the treatment of IBD. For the past few years CRISPR technology has drastically revolutionized DNA engineering and biomedical research field. We are beginning to see its application in gene manipulation of sickle cell disease,human immunodeficiency virus resistant embryologic twin gene modification and IBD genes such as Gatm(Glycine amidinotransferase, mitochondrial),nucleotide-binding oligomerization domain-containing protein 2, KRT12 and other genes implicated in adaptive immune convergence pathways have been subjected to gene editing, however there are very few publications. Furthermore,since Crohn's disease and ulcerative colitis have shared disease susceptibility and share genetic gene profile, it is paramount and is more advantageous to use CRISPR technology to maximize impact. Although, currently CRISPR does have its limitations due to limited number of specific Cas enzymes, off-target activity,protospacer adjacent motifs and crossfire between different target sites. However,these limitations have given researchers further insight on how to augment and manipulate enzymes to enable precise gene excision and limit crossfire between target sites. 展开更多

The structure and function of brain networks have been altered in patients with end-stage renal disease(ESRD).Manifold regularization(MR)only considers the pairing relationship between two brain regions and cannot represent functional interactions or higher-order relationships between multiple brain regions.To solve this issue,we developed a method to construct a dynamic brain functional network(DBFN)based on dynamic hypergraph MR(DHMR)and applied it to the classification of ESRD associated with mild cognitive impairment(ESRDaMCI).The construction of DBFN with Pearson’s correlation(PC)was transformed into an optimization model.Node convolution and hyperedge convolution superposition were adopted to dynamically modify the hypergraph structure,and then got the dynamic hypergraph to form the manifold regular terms of the dynamic hypergraph.The DHMR and L_(1) norm regularization were introduced into the PC-based optimization model to obtain the final DHMR-based DBFN(DDBFN).Experiment results demonstrated the validity of the DDBFN method by comparing the classification results with several related brain functional network construction methods.Our work not only improves better classification performance but also reveals the discriminative regions of ESRDaMCI,providing a reference for clinical research and auxiliary diagnosis of concomitant cognitive impairments. 展开更多

Liver diseases are one of the leading causes of mortality in the world. The hepatic illnesses, which include inherited metabolic disorders, hemophilias and viralhepatitides, are complex and currently difficult to treat. The maturation of gene therapy has heralded new avenues for developing effective intervention for these diseases. DNA modification using gene therapy is now possible and available technology may be exploited to achieve long term therapeutic benefit. The ability to edit DNA sequences specifically is of paramount importance to advance gene therapy for application to liver diseases. Recent development of technologies that allow for this has resulted in rapid advancement of gene therapy to treat several chronic illnesses. Improvements in application of derivatives of zinc finger proteins(ZFPs), transcription activator-like effectors(TALEs), homing endonucleases(HEs) and clustered regularly interspaced palindromic repeats(CRISPR) and CRISPR associated(Cas) systems have been particularly important. These sequence-specific technologies may be used to modify genes permanently and also to alter gene transcription for therapeutic purposes. This review describes progress in development of ZFPs, TALEs, HEs and CRISPR/Cas for application to treating liver diseases. 展开更多

Orphan diseases are rare diseases that affect less than 200000 individuals within the United States.Most orphan diseases are of neurologic and genetic origin.With the current advances in technology,more funding has been devoted to developing therapeutic agents for patients with these conditions.In our review,we highlight emerging options for patients with neurologic orphan diseases,specifically including diseases resulting in muscular deterioration,epilepsy,seizures,neurodegenerative movement disorders,inhibited cognitive development,neuron deterioration,and tumors.After extensive literature review,gene therapy offers a promising route for the treatment of neurologic orphan diseases.The use of clustered regularly interspaced palindromic repeats/Cas9 has demonstrated positive results in experiments investigating its role in several diseases.Additionally,the use of adeno-associated viral vectors has shown improvement in survival,motor function,and developmental milestones,while also demonstrating reversal of sensory ataxia and cardiomyopathy in Friedreich ataxia patients.Antisense oligonucleotides have also been used in some neurologic orphan diseases with positive outcomes.Mammalian target of rapamycin inhibitors are currently being investigated and have reduced abnormal cell growth,proliferation,and angiogenesis.Emerging innovations and the role of genetic treatments open a new window of opportunity for the treatment of neurologic orphan diseases. 展开更多

Objective: To analyze the similarities and differences of the applications of "the lung and large intestine being interior-exteriorly related"between the ancient and modern clinical practices, and to reveal the theory meaning.Method: Based on the ancient and modern medical cases database, 245 ancient medical records and 373 modern medical records were studied with the general statistical description and analysis of association rules, and the results were compared to summarize the similarities and differences of the regular pattern of syndrome and treatment on lung-large intestine related diseases in ancient and modern medical records.Results: In modern medical cases, intestinal diseases appeared with the main symptom of constipation due to deficiency of lung qi and qi stagnation of large intestine were always treated by purgation together with replenishing and restoring lung qi. In ancient medical cases, large intestine heat was always caused by lung heat and a variety of diarrhea symptoms appeared. They were always treated by clearing heat and moistening lungs. In addition, the symptom of bound stool caused by qi stagnation of large intestine due to lung qi stagnation was always treated by lowering lung qi to regulate and smooth large intestine qi. And Armeniae Amarum Semen was used by both as a core medicinal herb.Conclusion: Ascending-descending of qi movement is the core of the lung and large intestine relationship. In other words, the lung and the large intestine communicate through qi. 展开更多

Purpose-Chronic diseases are considered as one of the serious concerns and threats to public health across the globe.Diseases such as chronic diabetes mellitus(CDM),cardio vasculardisease(CVD)and chronic kidney disease(CKD)are major chronic diseases responsible for millions of death.Each of these diseases is considered as a risk factor for the other two diseases.Therefore,noteworthy attention is being paid to reduce the risk of these diseases.Agigantic amount of medical data is generated in digital form from smart healthcare appliances in the current era.Although numerous machine learning(ML)algorithms are proposed for the early prediction of chronic diseases,these algorithmic models are neither generalized nor adaptive when the model is imposed on new disease datasets.Hence,these algorithms have to process a huge amount of disease data iteratively until the model converges.This limitation may make it difficult forMLmodels to fit and produce imprecise results.A single algorithm may not yield accurate results.Nonetheless,an ensemble of classifiers built from multiple models,that works based on a voting principle has been successfully applied to solve many classification tasks.The purpose of this paper is to make early prediction of chronic diseases using hybrid generative regression based deep intelligence network(HGRDIN)model.Design/methodology/approach-In the proposed paper generative regression(GR)model is used in combination with deep neural network(DNN)for the early prediction of chronic disease.The GR model will obtain prior knowledge about the labelled data by analyzing the correlation between features and class labels.Hence,the weight assignment process of DNN is influenced by the relationship between attributes rather than random assignment.The knowledge obtained through these processes is passed as input to the DNN network for further prediction.Since the inference about the input data instances is drawn at the DNN through the GR model,the model is named as hybrid generative regression-based deep intelligence network(HGRDIN).Findings-The credibility of the implemented approach is rigorously validated using various parameters such as accuracy,precision,recall,F score and area under the curve(AUC)score.During the training phase,the proposed algorithm is constantly regularized using the elastic net regularization technique and also hypertuned using the various parameters such as momentum and learning rate to minimize the misprediction rate.The experimental results illustrate that the proposed approach predicted the chronic disease with a minimal error by avoiding the possible overfitting and local minima problems.The result obtained with the proposed approach is also compared with the various traditional approaches.Research limitations/implications-Usually,the diagnostic data are multi-dimension in nature where the performance of the ML algorithm will degrade due to the data overfitting,curse of dimensionality issues.The result obtained through the experiment has achieved an average accuracy of 95%.Hence,analysis can be made further to improve predictive accuracy by overcoming the curse of dimensionality issues.Practical implications-The proposedML model can mimic the behavior of the doctor’s brain.These algorithms have the capability to replace clinical tasks.The accurate result obtained through the innovative algorithms can free the physician from the mundane care and practices so that the physician can focus more on the complex issues.Social implications-Utilizing the proposed predictive model at the decision-making level for the early prediction of the disease is considered as a promising change towards the healthcare sector.The global burden of chronic disease can be reduced at an exceptional level through these approaches.Originality/value-In the proposed HGRDIN model,the concept of transfer learning approach is used where the knowledge acquired through the GR process is applied on DNN that identified the possible relationship between the dependent and independent feature variables by mapping the chronic data instances to its corresponding target class before it is being passed as input to the DNN network.Hence,the result of the experiments illustrated that the proposed approach obtained superior performance in terms of various validation parameters than the existing conventional techniques. 展开更多
