SimThyr 4.0 released

We are pleased to announce SimThyr 4.0, a major re-write of the popular virtual thyroid homeostasis software.

This version features a plethora of new functions, including but not limited to null isocline plots, enhanced data export options and model annotations supporting the creation of MIRIAM-compliant models. This functionality required a partial re-implementation of the simulation engine and more than 130 SVN commits. In additions, multiple bugs have been fixed.... read more

Recent in silico study validates SPINA with SimThyr

A recently published perspective article, which was authored by an international team of contributors in the journal Frontiers in Endocrinology, reviews theoretical background and diagnostic utility of SPINA-GT, SPINA-GD and other calculated parameters of thyroid homeostasis. In addition to summarizing the results of clinical studies covering more than 10,000 subjects it reports results of computer simulations with SimThyr. The authors of this silico study post-processed the output of sensitivity analysis with SimThyr with custom R scripts to deliver a semi-deterministic Monte Carlo simulation. The results confirm earlier observations that SPINA has higher reliability than native concentrations of TSH and peripheral thyroid hormones.... read more

For the second time SimThyr receives the eLearning Label of Ruhr University Bochum

We are excited that for the second time SimThyr has received the eLearning Label of the Ruhr University of Bochum. This label is bestowed as accompanying software of a series of lectures on internal medicine, which is enhanced by computer simulations and exercises with SimThyr. See https://twitter.com/SimThyrTeam/status/620685839857766400 for details.

SimThyr 3.3.3 available

SimThyr has been updated to version 3.3.3. This bug-fix release addresses two issues affecting the editor for structure parameters.

SimThyr 3.3.3 is available from http://simthyr.sf.net for Mac OS X, Windows and Linux.

SimThyr helps to identify new mechanisms of thyroid homeostasis.

Two recent research papers suggest that an additional mechanism might control T3 secretion in humans. Integration of in silico-analyses with SimThyr and observation of data of more than 1000 patients with and without substitution therapy with levothyroxine (L-T4) gave new hints that in humans TSH might stimulate deiodinase activity in vivo.

It is known for long time that cAMP up-regulates both type 1 and type 2 deiodinase, and it could also be shown that TSH (which uses cAMP as second messenger) is able to stimulate deiodination, but these observations resulted from animal experiments and cell culture investigations only. It was unknown if they are of any relevance in humans and on the level of the whole organism.... read more

SimThyr 3.3 released

On the occasion of the World Thyroid Day we have released SimThyr 3.3.

The new version introduces significant new features, first of all support for two-way sensitivity analysis. This technique allows for studying the combined effect of two structural parameters on a behavioural parameter (i.e. hormone level). Additionally, SimThyr 3.3 adopts version handling for scenario files, an option to switch off the circadian TRH rhythm and more flexible handling of units of measurement based on PUMA Repository, Last but not least some bugs have been fixed.... read more
