A machine vision-based in situ probe for automated on-line measurement of cell density and viability by dark field microscopy, image processing and pattern recognition

Author(s) : Wei, Ning
Description : The goal of this thesis is to develop an on-line probe that can be implemented to measure the in situ cell density and viability in bioreactors. This task includes not only hardware development, but also the development of suitable software that can fast and accurately process the signal generated b...

iTRAQ-Coupled 2-D LC-MS/MS Analysis of Membrane Protein Profile in Escherichia coli Incubated with Apidaecin IB

Author(s) : Zhou, Yusi , Chen, Wei Ning
Description : Apidaecins are a series of proline-rich, 18- to 20-residue antimicrobial peptides produced by insects. They are predominantly active against the Gram-negative bacteria. Previous studies mainly focused on the identification of their internal macromolecular targets, few addressed on the action of apid...

The RS Generalized Lambda Distribution Based Calibration Model

Author(s) : Steve Su , Abeer Hasan , Wei Ning
Description : We propose a flexible linear calibration model with errors from RS (Ramberg & Schmeiser, 1974) generalized lambda distribution ($Glambda D$). We demonstrate the derivation of the maximum likelihood estimates of RS $Glambda D$ parameters and examine the estimation performance using a simulation s...

DLEC1 Expression Is Modulated by Epigenetic Modifications in Hepatocelluar Carcinoma Cells: Role of HBx Genotypes

Author(s) : Dandan Niu , Huixing Feng , Wei Ning Chen
Description : Deleted in Lung and Esophageal Cancer 1 (DLEC1) is a functional tumor suppressor gene (TSG). It has been found to be silenced in a variety of human cancers including hepatocellular carcinoma (HCC). The silencing of DLEC1 can be modulated by epigenetic modifications, such as DNA hypermethylation and ...

Association of SAP130/SF3b-3 with Cullin-RING ubiquitin ligase complexes and its regulation by the COP9 signalosome

Author(s) : Menon Suchithra , Tsuge Tomohiko , Dohmae Naoshi , Takio Koji , Wei Ning
Description :

Abstract

Background

Cullin-RING ubiquitin E3 ligases (CRLs) are regulated by modification of an ubiquitin-like protein, Nedd8 (also known as Rub1) on the cullin subunit. Neddylation is shown to facilitate E3 complex assembly; while un-neddylated cullins are bound by CAND1 that preve...

An initial biochemical and cell biological characterization of the mammalian homologue of a central plant developmental switch, COP1

Author(s) : Yi Chunling , Wang Haiyang , Wei Ning , Deng Xing
Description :

Abstract

Background

Constitutive photomorphogenic 1 (COP1) has been defined as a central regulator of photomorphogenic development in plants, which targets key transcription factors for proteasome-dependent degradation. Although COP1 mammalian homologue has been previously reported,...

A machine vision system for automated non-invasive assessment of cell viability via dark field microscopy, wavelet feature selection and classification

Author(s) : Wei Ning , Flaschel Erwin , Friehs Karl , Nattkemper Tim
Description :

Abstract

Background

Cell viability is one of the basic properties indicating the physiological state of the cell, thus, it has long been one of the major considerations in biotechnological applications. Conventional methods for extracting information about cell viability usually nee...
