The aim of this paper is to develop a rapid, and highly sensitive quantitative HPLC fingerprint method with multiple indicators by using the Compound Chinese Medicine Wuwei Changyanning granule and 5 herbs in the prescription. The quantitative fingerprint chromatogram with multiple indicators was investigated. ⅰ)6 compositions included rutin, gallic acid, chlorogenic acid, atractylenolideⅠ, pac...

The characterization of microbial community structure via 16S rRNA gene profiling has been greatly advanced in recent years by the introduction of amplicon pyrosequencing. The possibility of barcoding gives the opportunity to massively screen multiple samples from environmental or clinical sources for community details. However, an on-going debate questions the reproducibility and semi-quantita...

Repetitive sequence-based polymerase chain reaction fingerprinting was used to characterize 23 vancomycin-nonsusceptible enterococcal isolates from 2003 to 2004. Five genetically related clusters spanned geographically distinct referring centers. DNA fingerprinting showed infant-to-infant transmission from referring institutions. Thus, community healthcare facilities are a source of vancomycin-...

background: colibacillosis is one of the most economically important diseases of poultry worldwide. objectives: this study was conducted to examine the clonal relatedness and typing of 95 avian escherichia coli isolates by eric-pcr. methods: sixty-three e. coli isolates from two common manifestations of colibacillosis (yolk sac infection and colisepticemia) and 32 isolates from feces of apparen...

We cultured 126 Pasteurella multocida isolates, 92 from water and 34 from sediment samples collected from wetlands in the Pacific and Central flyways of the United States between 1996 and 1999. Most (121) of the isolates were P. multocida serotype 1, but serotypes 3, 3/4, 10, and 11 were also found. Many (82) of the isolates were further characterized by DNA fingerprinting procedures and tested...

In this work we introduce a novel method for source code fingerprinting based on frequent pattern discovery using a graph grammar induction system, and use it for detecting cases of plagiarism. This approach is radically different from others in that we are not looking for similarities between documents, but similarities between fingerprints, which are made up of recurring patterns within the s...

This work was conducted to examine the composition and electrochemical activity of the bacterial community inhabiting lake Furnas sediments (Azores). Fingerprinting analysis of the bacterial 16S rRNA gene fragment was done by denaturing gradient gel electrophoresis. The sequences retrieved from lake Furnas sediments were affiliated to Bacteroidetes/Chlorobi group, Chloroflexi, Alfa-, Delta-, an...

Website fingerprinting enables an attacker to infer the source of a web page when a client is browsing through encrypted or anonymized network connections. We present a new website fingerprinting attack based on fingerprints extracted from random decision forests and evaluate performance on three separate data sets consisting of both standard web pages as well as Tor hidden services. Within the...
