Two dimensional gel electrophoresis (2-DE), isoelectric focusing (IEF) and agarose gel electrophoresis (AGE) were used to examine cerebrospinal fluid (CSF) and sera from 22 patients with confirmed multiple sclerosis, 11 patients with probable multiple sclerosis and 20 control patients with non-inflammatory neurological diseases of the central nervous system (CNS). All of the 22 patients with co...

Erythropoietin (Epo) is produced primarily in the kidneys upon low blood oxygen availability and stimulates erythropoiesis in the bone marrow. Recombinant human Epo (rHuEpo), a drug developed to increase arterial oxygen content in patients, is also illicitly used by athletes to improve their endurance performance. Therefore, a robust and sensitive test to detect its abuse is needed. The aim of ...

The analysis and characterizations of complex protein mixtures are the central aims of proteomics. The core technology of proteomics is 2DE which simultaneously separates and displays hundreds to thousands of proteins. In the 2DE technique, the sample preparation step with high protection against proteolysis is one of the necessary steps for high quality resolution of proteins in 2DE maps. The ...

The Seed Proteome Web Portal (SPWP; http://www.seed-proteome.com/) gives access to information both on quantitative seed proteomic data and on seed-related protocols. Firstly, the SPWP provides access to the 475 different Arabidopsis seed proteins annotated from two dimensional electrophoresis (2DE) maps. Quantitative data are available for each protein according to their accumulation profile d...

BACKGROUND There are two ways that statistical methods can learn from biomedical data. One way is to learn classifiers to identify diseases and to predict outcomes using the training dataset with established diagnosis for each sample. When the training dataset is not available the task can be to mine for presence of meaningful groups (clusters) of samples and to explore underlying data structur...

Individuals chronically infected with hepatitis B or C virus (HBV, HCV) are at high risk for the development of hepatocellular carcinoma (HCC), with disease progression occurring relentlessly over many years. The diagnosis of HCC usually occurs at late stages in the disease when there are few effective treatment options and the prognosis for patients with HCC is very poor. The long latency peri...

We study the problem of how to cover simple polygonal rectilinear regions by a small set of axis–parallel ellipses. This question is well motivated by a special pattern recognition task where one has to identify ellipse shaped protein spots in 2–dimensional electrophoresis images. We present and discuss various algorithmic approaches towards this problem ranging from a brute force method, to a ...

background: lipopolysaccharides (lpss) and several antigenic proteins of brucella have been considered for preparation of diagnostic reagents and subunit vaccines. the objective of this study was to identify and compare immunogens of b. abortus s19 which induce humoral immune responses in human, goat and rabbit.   material and methods: the bacterial whole cell extract was prepared in extraction...
