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

arXiv, 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 ...

Global trends and epidemiological shifts in gastrointestinal cancers: insights from the past four decades

Cancer Communications, EarlyView.
Abstract Background The epidemiological profiles of gastrointestinal (GI) cancers vary across countries and over time, largely reflecting variations in risk factors and screening practices. We aimed to provide an overview of the current global burden of the five major types of GI cancers and conduct an updated evaluation of the long‐term trends of GI ...

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

arXiv, 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 ...

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

Frontiers 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]

arXiv, 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.

South African Propolis: Anti‐Helicobacter pylori Activity, Chemistry, and Toxicity

Chemistry &Biodiversity, EarlyView.
ABSTRACT Propolis, a resin‐like substance produced by bees, has previously shown antimicrobial activity against the ulcer‐causing gut pathogen Helicobacter pylori. South African propolis, however, was yet to be investigated. This study aimed to investigate a comprehensive range of South African propolis for its antimicrobial activity against H.

Gastric cancer and Helicobacter pylori: a combined analysis of 12 case control studies nested within prospective cohorts [PDF]

, 2001
BACKGROUND: The magnitude of the association between Helicobacter pylori and incidence of gastric cancer is unclear. H pylori infection and the circulating antibody response can be lost with development of cancer; thus retrospective studies are ...

Citrus Flavonoids as Antimicrobials

Chemistry &Biodiversity, EarlyView.
Citrus flavonoids are powerful and versatile antimicrobials whose mechanism of action often involves disruption of the bacterial membrane, thereby minimizing antimicrobial resistance. This study provides a unified perspective. ABSTRACT Citrus flavonoids are highly bioactive compounds exerting numerous health benefits including anticancer, antioxidant ...
