Bistable equilibrium points of mercury body burden [PDF]

open access: yes, 2007
In the last century mercury levels in the global environment have tripled as a result of increased pollution from industrial, occupational, medicinal and domestic uses \cite{BaMe03}. Glutathione is known to be the main agent responsible for the excretion

Modeling drug- and chemical- induced hepatotoxicity with systems biology approaches

open access: yesFrontiers in Physiology, 2012
We provide an overview of computational systems biology approaches as applied to the study of chemical- and drug-induced toxicity. The concept of ‘toxicity pathways’ is described in the context of the 2007 US National Academies of Science report ...

Toxicology testing steps towards computers [PDF]

open access: yesLab Animal, 2019
Can the computer eliminate the lab animal? As computational methods become more advanced and data more freely available, in silico modeling approaches have growing potential to help reduce the number of animals needed to test chemical toxicity.

Mycotoxin exposure and human cancer risk : a systematic review of epidemiological studies

open access: yes, 2020
In recent years, there has been an increasing interest in investigating the carcinogenicity of mycotoxins in humans. This systematic review aims to provide an overview of data linking exposure to different mycotoxins with human cancer risk. Publications (

Discriminating Different Classes of Toxicants by Transcript Profiling [PDF]

open access: yes, 2004
Male rats were treated with various model compounds or the appropriate vehicle controls. Most substances were either well-known hepatotoxicants or showed hepatotoxicity during preclinical testing.

Predicting toxicity of chemicals: software beats animal testing

open access: yesEFSA Journal, 2019
We created earlier a large machine‐readable database of 10,000 chemicals and 800,000 associated studies by natural language processing of the public parts of Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) registrations until

A new approach methodology to identify tumorigenic chemicals using short-term exposures and transcript profiling

open access: yesFrontiers in Toxicology
Current methods for cancer risk assessment are resource-intensive and not feasible for most of the thousands of untested chemicals. In earlier studies, we developed a new approach methodology (NAM) to identify liver tumorigens using gene expression ...
