PHDMF: A Flexible and Scalable Personal Health Data Management Framework Based on Blockchain Technology.

Currently, most of the personal health data (PHD) are managed and stored separately by individual medical institutions. When these data need to be shared, they must be transferred to a trusted management center and approved by data owners through the third-party endorsement technology. Therefore, it is difficult for personal health data to be shared and circulated over multiple medical institutions.

Efficacy and safety of Xiyanping injection in the treatment of COVID-19: A multicenter, prospective, open-label and randomized controlled trial.

[Real world analysis to explore Xiyanping injection combined with other drugs for hand-foot-mouth disease].

Integrated network analysis was used in this paper to analyze Xiyanping injection combined therapy for hand-foot-mouth disease based on the registered research data of 3 204 cases. It was found that the drug combination therapy was almost consistent with the guidelines for the diagnosis and treatment of hand foot mouth disease, but there were some problems to be noticed: there were too many applications of antibiotics, more than the need in preventing secondary infection; and ribavirin was not necessary for use. This article showed that the clinical antibacterial and antiviral values of Xiyanping injection has not been well recognized for hand-foot-mouth disease.

There exists a kind of symbiotic bacterium named "Candidatus Arsenophonus nilaparvatae" in the brown planthopper (BPH), Nilaparvata lugens. After being filtered and assembled from the BPH genome sequencing project, the genome sequence of this bacterial symbiont was obtained. After initial analysis based on the genome, we have found its potential role to synthesize B vitamins for the host.

Genomic Analysis of an Ascomycete Fungus from the Rice Planthopper Reveals How It Adapts to an Endosymbiotic Lifestyle.

A number of sap-sucking insects harbor endosymbionts, which are thought to play an important role in the development of their hosts. One of the most important rice pests, the brown planthopper (BPH), Nilaparvata lugens (Stål), harbors an obligatory yeast-like symbiont (YLS) that cannot be cultured in vitro. Genomic information on this YLS would be useful to better understand its evolution.

Bicaudal-C plays a vital role in oogenesis in Nilaparvata lugens (Hemiptera: Delphacidae).

Bicaudal-C (Bic-C) was originally identified in a Drosophila melanogaster mutagenesis screen and plays vital roles in embryogenesis. In this study, we characterized the Bic-C gene in the brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae), an insect pest that undergoes incomplete metamorphosis. Our result showed that N.

Two insulin receptors determine alternative wing morphs in planthoppers.

Wing polyphenism is an evolutionarily successful feature found in a wide range of insects. Long-winged morphs can fly, which allows them to escape adverse habitats and track changing resources, whereas short-winged morphs are flightless, but usually possess higher fecundity than the winged morphs. Studies on aphids, crickets and planthoppers have revealed that alternative wing morphs develop in response to various environmental cues, and that the response to these cues may be mediated by developmental hormones, although research in this area has yielded equivocal and conflicting results about exactly which hormones are involved.

Genomes of the rice pest brown planthopper and its endosymbionts reveal complex complementary contributions for host adaptation.

Background: The brown planthopper, Nilaparvata lugens, the most destructive pest of rice, is a typical monophagous herbivore that feeds exclusively on rice sap, which migrates over long distances. Outbreaks of it have re-occurred approximately every three years in Asia. It has also been used as a model system for ecological studies and for developing effective pest management.

Techniques combining chromosome conformation capture and next generation sequencing can capture chromatin structure information and has been applied to several different species and cell lines. We built 3DGD (3D Genome Database), a database that currently collected Hi-C data on four species, for easy accessing and visualization of chromatin 3D structure data.

A Metabolomics Profiling Study in Hand-Foot-and-Mouth Disease and Modulated Pathways of Clinical Intervention Using Liquid Chromatography/Quadrupole Time-of-Flight Mass Spectrometry.

Hand-foot-and-mouth disease (HFMD), with poorly understood pathogenesis, has become a major public health threat across Asia Pacific. In order to characterize the metabolic changes of HFMD and to unravel the regulatory role of clinical intervention, we have performed a metabolomics approach in a clinical trial. In this study, metabolites profiling was performed by liquid chromatography/quadrupole time-of-flight mass spectrometry (LC-Q-TOF-MS) platform from the HFMD clinical patient samples.

Molecular characterization of the flightin gene in the wing-dimorphic planthopper, Nilaparvata lugens, and its evolution in Pancrustacea.

Flightin was initially identified in Drosophila melanogaster. Previous work has shown that Drosophila flightin plays a key role in indirect flight muscle (IFM) function and has limited expression in the IFM. In this study, we demonstrated that flightin is conserved across the Pancrustacea species, including winged insects, non-winged insects, non-insect hexapods and several crustaceans.

Genome of a Bombyx mori nucleopolyhedrovirus strain isolated from India.

Bombyx mori nucleopolyhedrovirus (BmNPV), a member of the Baculoviridae, is a major pathogen of silkworm and has also been recently developed as an expression vector for heterologous gene expression in the silkworm larvae and pupae. To better understand the diversity of this important baculovirus, we sequenced the complete genome of the BmNPV strain isolated from India, where its host is available throughout the year due to its tropical climate. The genome of the Indian strain consists of 127,879 nucleotides, with a G+C content of 40.

Chitin synthase 1 gene and its two alternative splicing variants from two sap-sucking insects, Nilaparvata lugens and Laodelphax striatellus (Hemiptera: Delphacidae).

Chitin synthase (CHS) is an enzyme that is required for chitin formation in insect cuticles and other tissues. In this study, CHS genes from two destructive rice insect pests, the brown planthopper Nilaparvata lugens and the small brown planthopper Laodelphax striatellus, were cloned. Phylogenetic analysis showed that these genes belonged to class CHS1 of the CHS gene family.

Disruption of Bombyx mori nucleopolyhedrovirus ORF71 (Bm71) results in inefficient budded virus production and decreased virulence in host larvae.

The Bombyx mori nucleopolyhedrovirus (BmNPV) is a baculovirus that selectively infects domestic silkworm. BmNPV ORF71 (Bm71) is not a core set gene in baculovirus and shares 92 % amino acid sequence identity with Autographa californica multinucleocapsid NPV ORF88 (Ac88/cg30). Previously, it has been reported that virus lacking Ac88 had no striking phenotypes in cell lines or host larvae.

A platform to standardize, store, and visualize proteomics experimental data.

With the development of functional genomics research, large-scale proteomics studies are now widespread, presenting significant challenges for data storage, exchange, and analysis. Here we present the Integrated Proteomics Exploring Database (IPED) as a platform for managing proteomics experimental data (both process and result data). IPED is based on the schema of the Proteome Experimental Data Repository (PEDRo), and complies with the General Proteomics Standard (GPS) drafted by the Proteomics Standards Committee of the Human Proteome Organization.

The contribution of cis-regulatory elements to head-to-head gene pairs' co-expression pattern.

Transcription regulation is one of the most critical pipelines in biological process, in which cis-elements play the role as gene expression regulators. We attempt to deduce the principles underlying the co-expression of "head-to-head" gene pairs by analyzing activities or behaviors of the shared cis-elements. A network component analysis was performed to estimate the impact of cis-elements on gene promoters and their activities under different conditions.

Gene expression module-based chemical function similarity search.

Investigation of biological processes using selective chemical interventions is generally applied in biomedical research and drug discovery. Many studies of this kind make use of gene expression experiments to explore cellular responses to chemical interventions. Recently, some research groups constructed libraries of chemical related expression profiles, and introduced similarity comparison into chemical induced transcriptome analysis.

EPGD: a comprehensive web resource for integrating and displaying eukaryotic paralog/paralogon information.

Gene duplication is common in all three domains of life, especially in eukaryotic genomes. The duplicates provide new material for the action of evolutionary forces such as selection or genetic drift. Here we describe a sophisticated procedure to extract duplicated genes (paralogs) from 26 available eukaryotic genomes, to pre-calculate several evolutionary indexes (evolutionary rate, synonymous distance/clock, transition redundant exchange clock, etc.
