Synthetic Biology

5.0K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Model Approaches for Pharmacokinetic Data: Physiological Models

131
Physiological models in pharmacokinetics are instrumental in understanding the distribution and elimination of drugs within the body. These models describe the drug concentration within target organs, influenced by factors such as drug uptake, tissue volume, and blood flow. Drug uptake is governed by the partition coefficient, which signifies the drug concentration ratio in tissue to that in the blood. The blood flow rate to a specific tissue is expressed as Qt, and the rate of change in tissue...

Mechanistic Models: Overview of Compartment Models

183
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Model Approaches for Pharmacokinetic Data: Distributed Parameter Models

136
Pharmacokinetic models are mathematical constructs that represent and predict the time course of drug concentrations in the body, providing meaningful pharmacokinetic parameters. These models are categorized into compartment, physiological, and distributed parameter models.
The distributed parameter models are specifically designed to account for variations and differences in some drug classes. This model is particularly useful for assessing regional concentrations of anticancer or...

Induced-fit Model01:13

Induced-fit Model

82.8K
Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Area of Science:

  • Computational Biology
  • Bioinformatics
  • Systems Biology

Background:

  • Semantic annotation using Resource Description Framework (RDF) is vital for biosimulation model reusability and reproducibility.
  • The Resource Description Framework query language (SPARQL) enables searching model entities but presents challenges due to its complexity and rigid syntax.
  • Existing tools like the NCBO Annotator face limitations in effectively identifying relevant ontology classes from natural language queries.

Purpose of the Study:

  • To develop NLIMED, an interface that translates natural language queries into SPARQL queries.
  • To facilitate efficient querying and discovery of entities within biosimulation models stored in repositories like the Physiome Model Repository (PMR) and BioModels database.
  • To improve the accessibility and usability of semantic annotations for biosimulation models.

Main Methods:

  • NLIMED employs natural language processing (NLP) techniques to 'chunk' natural language queries into phrases.
  • Ontology classes and predicates are identified and annotated using various NLP tools.
  • The annotated components are composed into SPARQL queries, ranked using a SPARQL Composer and an indexing system.

Main Results:

  • NLIMED demonstrates superior effectiveness compared to the NCBO Annotator in identifying relevant ontology classes from natural language queries.
  • The system successfully queries and discovers model entities from the Physiome Model Repository (PMR) and BioModels database.
  • NLIMED's approach adapts well to queries related to well-annotated models, as validated against historical query data from the PMR.

Conclusions:

  • NLIMED offers a user-friendly interface for querying complex biosimulation model repositories.
  • The natural language to SPARQL conversion significantly enhances the discoverability and accessibility of biosimulation model components.
  • NLIMED promotes greater reusability and reproducibility of biosimulation models through improved data retrieval.
