Protein Networks02:26

Protein Networks

4.5K
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,...

Network Covalent Solids02:18

Network Covalent Solids

16.1K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Methods for Studying Drug Absorption: In vitro01:16

Methods for Studying Drug Absorption: In vitro

587
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

Network Function of a Circuit01:25

Network Function of a Circuit

681
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

Methods for Studying Drug Absorption: In situ01:09

Methods for Studying Drug Absorption: In situ

651
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

Area of Science:

  • Biomedical Informatics
  • Geographic Information Systems (GIS)
  • Clinical Research Management

Background:

  • International clinical trial databases like ClinicalTrials.gov lack geographic visualization capabilities.
  • Patient advocacy groups and researchers require tools to locate studies based on geographic proximity.
  • Existing data sources (ClinicalTrials.gov, PubMed, MEDLINE) are often disconnected, hindering comprehensive research network visualization.

Purpose of the Study:

  • To design and implement StudyPortal, an interactive online platform for geospatial searching and visualization of clinical trials.
  • To enable patients, healthcare providers, and researchers to identify and localize suitable clinical studies and research networks.
  • To integrate diverse data sources for a unified view of clinical research landscapes.

Main Methods:

  • Developed StudyPortal with a semantic layer for multilingual disease input and autosuggestion.
  • Integrated data from ClinicalTrials.gov and author affiliations from PubMed articles.
  • Utilized a geodatabase and maps for geospatial search and visualization of trial and publication data.
  • Validated visualization accuracy using expert review and external sources like Web of Science and WHO trial database.

Main Results:

  • StudyPortal successfully visualizes over 70% of clinical trials and over 90% of scientific articles.
  • The platform integrates disconnected sources (ClinicalTrials.gov, MEDLINE, geomaps) into a real-time geospatial view.
  • Preliminary implementation demonstrates the feasibility of a novel geospatial approach to clinical research landscapes.
  • Identified publication and trial-registration bias as limitations to visualization completeness.

Conclusions:

  • StudyPortal offers a novel solution for the geographic visualization and localization of clinical trials.
  • The platform enhances accessibility to clinical research by providing geospatial search capabilities.
  • Future development will focus on advanced search filters for recruitment status and intervention characteristics to further improve usability.
