Metagenomic analysis fecal microbiota of dysentery-like diarrhoea in a pig farm using next-generation sequencing.

Porcine enteric diseases including swine dysentery involves a wide range of possible aetiologies and seriously damages the intestine of pigs of all ages. Metagenomic next-generation sequencing is commonly used in research for detecting and analyzing pathogens. In this study, the feces of pigs from a commercial swine farm with dysentery-like diarrhea was collected and used for microbiota analysis by next-generation sequencing.

Endoscopic Ruler for varix size measurement: A multicenter pilot study.

Background: We invented Endoscopic Ruler, a new endoscopic device to measure the size of varices in patients with cirrhosis and portal hypertension.

Aim: To assess the feasibility and safety of Endoscopic Ruler, and evaluate the agreement on identifying large oesophageal varices (OV) between Endoscopic Ruler and the endoscopists, as well as the interobserver agreement on diagnosing large OV using Endoscopic Ruler.

Methods: We prospectively and consecutively enrolled patients with cirrhosis from 11 hospitals, all of whom got esophagogastroduodenoscopy (EGD) with Endoscopic Ruler.

Expression Profiles of Zebrafish () Lysozymes and Preparation of c-Type Lysozyme with High Bacteriolytic Activity against .

Lysozyme is a crucial component of the host's innate immune system. Due to its natural non-toxic and harmless characteristics, lysozyme is considered to be an ideal antibiotic substitute. In this study, we analyzed the expression profiles of lysozymes from zebrafish () in uninfected or -infected tissues using real-time quantitative PCR (qPCR).

Proteomic Profiling Skin Mucus of European Eel Infected with Anguillid Herpesvirus.

Anguillid herpesvirus 1 (AngHV) is an important viral pathogen affecting eel. This study was designed to investigate the potential molecular mechanisms and immune response elicited at the protein levels in the skin mucus of AngHV-infected . Tandem mass tag (TMT)-labelling proteomics with the liquid chromatography tandem mass spectrometry (LC-MS/MS) was used for performing quantitative identification of the proteins.

Evaluation of housekeeping genes as references for quantitative real-time PCR analysis of European eel, Anguilla anguilla.

Eels are important aquaculture species for which an increasing number of reference genes are being identified and applied. In this study, five housekeeping genes [RPL7 (ribosomal protein L7), 18 S (18 S ribosomal RNA), EF1A (elongation factor 1α), ACTB (β-actin) and GAPDH (glyceraldehyde-3-phosphate dehydrogenase)] were chosen to evaluate their reliability as reference genes for quantitative real-time PCR (qPCR) for the study of Anguilla anguilla. The expression of the selected genes in different eel tissues was determined using qPCR at different growth stages or upon challenge by Anguillid herpesvirus (AngHV), and the expression levels of these genes were then compared and evaluated using the geNorm and NormFinder algorithms.

Isolation of a novel adomavirus from cultured American eels, Anguilla rostrata, with haemorrhagic gill necrosis disease.

Recently, the culture of American eels (Anguilla rostrate) in China has been impacted by emergence of a disease with signs of haemorrhagic gill necrosis. The gills of diseased eels are covered with petecchia and they bleed when the operculum is pressed. In this study, a novel American eel adomavirus (AEAdoV) was isolated from the diseased eels using the eel ovary cell line (EO).

Anguillid herpesvirus 1 (AngHV) ORF95 encodes a late, structural envelope protein.

Anguillid herpesvirus 1 (AngHV) is one of the vital pathogenic agents found in the wild and cultured eel populations, which has brought significant losses to eel culture industry in China. In this study, AngHV ORF95 was characterized. Bioinformatics analysis showed that ORF95 putatively encodes a structural protein that is homologous to hemagglutinin-esterase (HE) protein of infectious salmon anemia virus (ISAV).

[Extracorporeal membrane oxygenation support in acute cardiorespiratory function failure patients after cardiac surgery].

Objective: To investigate the treatment experience of extracorporeal membrane oxygenation (ECMO) support after cardiac surgery.

Methods: Retrospectively analyze the clinical data of 117 postoperative patients supported with ECMO in cardiac intensive care unit from March 2005 to June 2008. There were 32 female and 85 male patients, with a mean age of (48.

[The genetic diversity and homology of Anabaena azollae and its host plant (Azolla) based on rapd analysis].

Symbiotic Anabeana azollae and its host plant Anabeana-free Azolla were isolated from 16 Azolla accessions representing different Azolla species or geographic origins.DNA polymorphic fragments were obtained by simultaneous RAPD amplification of both symbiont and host. The UPGMA clusters of Anabeana azollae and its host Azolla were established separately based on Dice coefficient caculation and a coordinated relationship was shown between Anabeana azollae and its Azolla host along both individual genetic divergence,but this genetic homology was reduced among different strains within Azolla species while the obvious mutants of Anabeana azollae were detected in some Azolla tested strains collected from different geographic area in the same host species.
