Imaging Biological Samples with Optical Microscopy01:18

Imaging Biological Samples with Optical Microscopy

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...
Drug Discovery: Overview01:26

Drug Discovery: Overview

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
ER Retrieval Pathway01:45

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...
Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.

Area of Science:

  • Biomedical Informatics
  • Information Retrieval
  • Computational Biology

Background:

  • Existing academic search systems are either general-purpose (e.g., PubMed) with flexible queries but unorganized results, or domain-specific (e.g., PPI Finder) with structured but context-limited results.
  • This dichotomy necessitates a new approach to efficiently search and retrieve biomedical information.

Purpose of the Study:

  • Introduce BOSS (Biomedical Object Search System), a novel search engine designed to bridge the gap between general and domain-specific search systems.
  • To provide users with a flexible yet structured way to query and retrieve biomedical information.

Main Methods:

  • BOSS indexes Maximal Coherent Semantic Units (MCSUs) such as phrases, clauses, or sentences, rather than entire documents.
  • Upon receiving a user query, BOSS identifies relevant objects within matching segments and aggregates these segments per object.
  • The system returns a ranked list of objects accompanied by their associated matching segments.

Main Results:

  • A working prototype of BOSS is accessible online.
  • The current BOSS version has indexed over 20 million biomedical article abstracts from 1996 to 2011.
  • The system demonstrates good scalability, leveraging a modified standard document-indexing model.

Conclusions:

  • BOSS effectively addresses the limitations of existing search systems by enabling context-free queries and delivering structured results.
  • The search engine enhances the technological capabilities for searching biomedical information.
  • BOSS offers a scalable and efficient solution for navigating the vast biomedical literature.
