Avoid Internal Loops in Steady State Flux Space Sampling [PDF]

open access: yesarXiv, 2012
As a widely used method in metabolic network studies, Monte-Carlo sampling in the steady state flux space is known for its flexibility and convenience of carrying out different purposes, simply by alternating constraints or objective functions, or appending post processes.

Measuring and estimating interaction between exposures on dichotomous outcome of a population [PDF]

open access: yesarXiv, 2015
In observational studies for the interaction between exposures on dichotomous outcome of a population, one usually uses one parameter of a regression model to describe the interaction, leading to one measure of the interaction. In this article, we use the conditional risk of outcome given exposures and covariates to describe the interaction and obtain ...

Risk factors in gastric cancer [PDF]

open access: yes, 2010
STATE OF THE ART: Gastric cancer (GC) is still a major health problem worldwide due to its frequency, poor prognosis and limited treatment options. At present prevention is likely to be the most effective means of reducing the incidence and mortality ...

Membrane-bound β-catenin degradation is enhanced by ETS2-mediated Siah1 induction in Helicobacter pylori-infected gastric cancer cells. [PDF]

open access: yes, 2017
β-catenin has two different cellular functions: intercellular adhesion and transcriptional activity. The E3 ubiquitin ligase Siah1 causes ubiquitin-mediated degradation of the cytosolic β-catenin and therefore, impairs nuclear translocation and oncogenic

Identification of Essential Proteins Using Induced Stars in Protein-Protein Interaction Networks [PDF]

open access: yesarXiv, 2017
In this work, we propose a novel centrality metric, referred to as star centrality, which incorporates information from the closed neighborhood of a node, rather than solely from the node itself, when calculating its topological importance. More specifically, we focus on degree centrality and show that in the complex protein-protein interaction ...

Impact of creatinine clearance on helicobacter pylori eradication rate in patients with peptic ulcer disease [PDF]

open access: yes, 2015
Introduction. Gastrointestinal complaints are common in patients with kidney failure. The aim of this study was to investigate the effect of creatinine clearance on Helicobacter pylori (HP) eradication rate in patients with peptic ulcer disease ...

Helicobacter suis affects the health and function of porcine gastric parietal cells [PDF]

open access: yes, 2016
The stomach of pigs at slaughter age is often colonized by Helicobacter (H.) suis, which is also the most prevalent gastric non-H. pylori Helicobacter (NHPH) species in humans. It is associated with chronic gastritis, gastric ulceration and other gastric

Increased circulating regulatory T cells and decreased follicular T helper cells are associated with colorectal carcinogenesis

open access: yesFrontiers in Immunology
ObjectiveColorectal cancer (CRC) is the third most prevalent cancer worldwide and is associated with high morbidity and mortality rates. Colorectal carcinogenesis occurs via the conventional adenoma-to-carcinoma and serrated pathways.

Multi-omic Network Regression: Methodology, Tool and Case Study [PDF]

open access: yesarXiv, 2018
The analysis of biological networks is characterized by the definition of precise linear constraints used to cumulatively reduce the solution space of the computed states of a multi-omic (for instance metabolic, transcriptomic and proteomic) model.
