Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein-protein Interfaces

14.8K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Combination Therapies and Personalized Medicine

6.2K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Genomics02:02

Genomics

41.0K
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...

Analysis of Population Pharmacokinetic Data01:12

Analysis of Population Pharmacokinetic Data

830
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Area of Science:

  • Biomedical Informatics
  • Data Science
  • Knowledge Discovery

Background:

  • Biomedical data is increasingly moving towards semi-structured formats like RDF and OWL.
  • Integrating heterogeneous data and discovering knowledge across domains is a significant challenge.
  • Identifying relationships between concepts within and across medical ontologies is crucial for research.

Purpose of the Study:

  • To develop a mechanism for predicate-oriented pattern analysis of heterogeneous ontologies.
  • To partition large datasets into smaller, related topics for focused knowledge discovery.
  • To generate meaningful queries for discovering cross-domain knowledge from interlinked data sources.

Main Methods:

  • Predicate-oriented pattern analysis to identify close relationships between predicates.
  • Generation of a similarity matrix based on predicate relationships.
  • Application of an unsupervised learning algorithm to partition data into topics.
  • Development of a prototype system named BmQGen for evaluation.

Main Results:

  • The model successfully partitions heterogeneous ontologies into smaller, related topics.
  • A similarity matrix effectively captures predicate relationships.
  • The unsupervised learning algorithm facilitates data partitioning.
  • BmQGen demonstrates the model's capability in knowledge discovery.

Conclusions:

  • The proposed model provides an effective approach for predicate-oriented pattern analysis in biomedical data.
  • This method aids in partitioning complex ontologies and discovering cross-domain knowledge.
  • BmQGen serves as a valuable tool for biomedical researchers to navigate and query large, interlinked datasets.
