Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence the...

Bioequivalence: Overview01:16

Bioequivalence: Overview

Pharmaceutical equivalents, by definition, are drug products with the same active ingredient in the same quantities, encapsulated in identical dosage forms, and intended for the same administration routes. These pharmaceutical equivalents are deemed bioequivalent if the bioavailability of the active entity in the drug preparations is similar. Moreover, pharmaceutical equivalents demonstrating bioequivalence are also regarded as therapeutically equivalent. This means that when used as directed,...
Bioavailability: Overview01:13

Bioavailability: Overview

Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...
Biostatistics: Overview01:20

Biostatistics: Overview

Biostatistics plays a crucial role in understanding and analyzing data in healthcare and biology. Biostatisticians conduct experiments, gather evidence, and draw meaningful conclusions using statistical methods and techniques. Different variables form the foundation of biostatistical analysis, allowing researchers to understand and interpret data effectively. These variables are classified into different types, each serving a specific purpose in statistical analysis.
Discrete variables are...
Genomics02:02

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Data Integration

Background:

  • Life scientists face challenges integrating diverse biological data from numerous databases due to non-standard interfaces and formats.
  • Data heterogeneity hinders the discovery and reuse of valuable biological resources.
  • The open-source Bio2RDF project aims to integrate biological data using Semantic Web technologies, but querying remains difficult due to non-uniform dataset representations.

Purpose of the Study:

  • To improve the Bio2RDF framework by enhancing data integration and standardization.
  • To simplify querying and data access across diverse biological datasets.
  • To promote the reuse of publicly funded biological resources.

Main Methods:

  • Consolidated open-source scripts into a single GitHub repository.
  • Redeveloped scripts using a common API for normalized IRIs and a centralized dataset registry.
  • Mapped dataset-specific types and relations to the Semanticscience Integrated Ontology (SIO).

Main Results:

  • Achieved tighter integration across 19 new and updated RDF datasets within Bio2RDF.
  • Demonstrated simplified federated queries across multiple Bio2RDF endpoints.
  • Improved the quality and accessibility of linked data in the Bio2RDF network.

Conclusions:

  • The Bio2RDF update represents a significant advancement for the open-source linked data framework.
  • Enhanced data quality and simplified local access/recreation of linked data.
  • Future work includes identifying priority databases and expanding vocabulary coverage beyond SIO.
