Predictive Toxicology Ontology Perspectives and Roadmap

Re: #OpenTox, ontology, new predictive toxicology systems

The following papers are now available from the new issue of Altex:

Toxicology ontology perspectives
This article provides an overview of some of the leading developments in
incorporating ontology into new knowledge-based systems in predictive toxicology.

A toxicology ontology roadmap
In this article we lay out the main justifications and needs for ontology
development to enable the building of interoperable predictive toxicology systems
and services for industry to design and test safer products.

OpenTox Toxicology Ontology Development

This article is just out online describing initial #OpenTox ontology work:

#OpenTox predictive toxicology framework: toxicological ontology and semantic media wiki-based OpenToxipedia

#OpenTox - #Bioclipse Cloud article

The final version of our first #OpenTox - #Bioclipse paper on getting our tox cloud working with the Bioclipse workbench for interactive design for safety purposes is now available in open access. See http://www.biomedcentral.com/1756-0500/4/487

Bioclipse and OpenTox partner up to create a unique workbench semantic web combination

#OpenTox and #Bioclipse have partnered up on a new open platform we hope you will try out!

We describe the combination of the Bioclipse workbench and distributed OpenTox web services to create a unique safety assessment exploration and design environment for chemists, biologists and toxicologists in the following new paper:

Computational toxicology using the OpenTox application programming interface and Bioclipse

I believe future developments of this platform are looking promising. Welcome your feedback!

OpenTox 1.0 - what we have reached on its third birthday

 


On the eve of its 3rd birthday, I told the story so far of our development of OpenTox in Slovenia last week.

The lecture (slides and video) recorded at the Josef Stefan institute in Ljubljana on "OpenTox - the creation of a semantic web for toxicology" is available at:
http://videolectures.net/solomon_hardy_semantic/

I look forward to that future "Sixth Sense" journey interoperating with OpenTox to revisit the Tamboti Trees in South Africa and the Mopane Trees in Namibia, and to test the delivery of safety advice from the distributed semantic knowledge of OpenTox 3.0 use cases in the field :)!

Innovation Questions for the field of Predictive Toxicology

What are key innovation questions for the field of predictive toxicology? I propose we discuss the following questions at our Knowledge Cafe at the #OpenTox 2011 meeting in Munich. We can use the discussions as a basis to formulate an innovation white paper to provide direction to innovators who can accelerate developments in the field with strategy and technology development.

A. Mechanistic Strategies - What are the key innovations needed to accelerate progress?

B. Predictive Metabolism - What is needed for a complete and reliable prediction of metabolites?

C. Computational Chemistry - Emerging challenges and opportunities in receptor-mediated predictive toxicology

D. Systems Biology - How can we bridge the divide between modelling molecular pathways and quantitative prediction at the organelle level?

E. Integrated Analysis - Experimental designs for optimising biomarker discovery

F. Kinetics - Extrapolating in vitro data to model human hazard and exposure

G. Weight of Evidence - Developing holistic approaches to compound profiling and prioritisation-based decision making

H. Read Across and Categories - What are the key components for a more rigorous approach to a best practice?

I. Regulatory Needs - How do we accelerate the acceptance of emerging scientific methods in regulatory applications?

J. High Content Assays - What information can they provide today and what are the key gaps requiring new innovation?



Greetings from OpenTox class in Buea, Cameroon

#OpenTox A la Koh! Njuah! Aleh Aleh! Greetings from the #SETAC #Africa workshop group here to the #OpenTox community. We find the tools interesting and would like more workshop activity and tutorials in the future. We are interested in applying tools to assessing the quality of our water, pollution from pesticides, effects of petroleum products on our communities. We are interested in assessing toxicity data, predicting acute toxic effects, evaluating longer term effects on human health such as development and reproductive toxicity, and applying ecotoxicity models for environmental risk assessment of our ecosystems.

OpenTox workshop, SETAC Africa - day 1

We managed to get quite a bit of software installed at the #OpenTox workshop at SETAC, Africa on Tuesday on about 25 laptops or so belonging to the group. But we still have to get a couple of final machines to setup.

As now we can work on some problems, we decided at day's end we could continue the workshop again today, although that was not originally planned, but why not. Perhaps we can run all week, until we all get tired out :)!

Our main challenge and delay with the Virtual Appliance installation was the final installation patch Roman and Nina discovered was needed over the weekend, as this was required to fix the removal of ontology service files from the temp directory upon a virtual machine restart. At least we can fix that bug in a nicer way for next time.

However yesterday, the final installation step required going onto the net for every machine in turn, which took most of the afternoon! We did not have any internet for several hours, but we finally were able to send a group member Anyi with cash down to a provider office to charge an account she had, which we were able to use in the afternoon (Thanks Anyi for saving the day!). It was not so reliable or fast a connection but we eventually got through on it, but only one machine could be on at a time.

It will be helpful if we can figure out the shared file folders facility between the Virtual Appliance for linux and Windows - but did not have time to do that yet.

Also, we installed and ran Bioclipse live over the one internet connection at the end of the afternoon and had it go out and fetch OpenTox resource and model information, and live for an example. We did it (just about)! I pointed out the new login profile setup Egon has just recently setup, and perhaps we can get that done for the group today.

Philip Judson also joined us and we were able to get Derek and Meteor setup on machines too. Based on his experience, he gave a nice overview on some factors we have to reflect on in using such in silico programs and methods!

Eventually the bus came and took us home - tired but at least installed :)! We will try to continue today!!
