Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.5K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Multicompartment Models: Overview01:14

Multicompartment Models: Overview

419
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Mechanistic Models: Compartment Models in Individual and Population Analysis

183
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Mechanistic Models: Overview of Compartment Models

285
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...

Classification of Systems-II

418
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Three-Compartment Open Model01:06

Three-Compartment Open Model

731
The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...

Area of Science:

  • Systems Biology
  • Computational Biology
  • Biochemical Modeling

Background:

  • Rule-based modeling offers a powerful approach to construct complex reaction networks by specifying rules for molecular interactions.
  • This method allows for detailed specification of sub-molecular domains, component states, binding status, and spatial information.
  • The use of 'wildcards' enables the definition of entire families of molecule complexes as patterns, simplifying models with multiple components, states, and compartments.

Purpose of the Study:

  • To provide the specification for Release 2 of Version 1 of the Systems Biology Markup Language (SBML) Level 3 Multi package.
  • To detail the extension of the SBML Level 3 core with the 'type' concept for Species and Compartment classes, enabling pattern-based species and multi-location existence.
  • To document minor corrections and clarifications without altering the core model description.

Main Methods:

  • Specification document for the SBML Level 3 Multi package, Release 2 of Version 1.
  • Extension of SBML Level 3 Version 1 core by incorporating the 'type' concept into Species and Compartment classes.
  • Description of how reaction rules can incorporate species patterns and multiple locations.

Main Results:

  • The SBML Level 3 Multi Package Version 1 (Release 2) extends SBML capabilities to support rule-based modeling with enhanced pattern matching and spatial information.
  • This standard facilitates the definition of complex biological models involving numerous species, states, and compartments.
  • Software tools like Simmune and BioNetGen support this standard, promoting interoperability of rule-based models.

Conclusions:

  • The SBML Level 3 Multi Package provides a standardized format for rule-based modeling in systems biology.
  • This specification enhances the ability to represent and exchange complex biochemical models, fostering collaborative research.
  • Release 2 focuses on errata correction and clarification, ensuring the stability and usability of the standard.
