MALDI-TOF Mass Spectrometry01:19

MALDI-TOF Mass Spectrometry

6.4K
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.Matrix-assisted laser desorption ionization (MALDI) is a commonly...

Combination Therapies and Personalized Medicine

5.8K
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...

Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

8.9K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Bone Marrow Sampling and Transplants

776
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Drug Discovery: Overview

10.8K
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...

Chi-square Analysis02:46

Chi-square Analysis

43.2K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

Area of Science:

  • Medical Informatics
  • Natural Language Processing
  • Biomedical Data Mining

Background:

  • MEDLINE records contain valuable biomedical information.
  • Identifying relationships between medical concepts is crucial for research and clinical practice.
  • Existing methods for concept extraction can be enhanced through sophisticated text mining techniques.

Purpose of the Study:

  • To develop and present a text mining application for extracting conceptually related concept pairs from MEDLINE.
  • To leverage MeSH (Medical Subject Headings) subheading combinations and SemRep (Semantic Representation) for concept relation extraction.
  • To provide a summary view and diversity indicators of related concepts for healthcare practitioners and researchers.

Main Methods:

  • The application utilizes user-specified MeSH heading-subheading pairs to identify co-occurring concepts.
  • A parallel process employs SemRep to extract concept pairs from MEDLINE record titles.
  • Extracted pairs from both methods are compared to generate a high-confidence subset for analysis.

Main Results:

  • The text mining application successfully extracts conceptually related concept pairs based on MeSH and SemRep.
  • A combined approach yields a high-confidence subset of related concepts.
  • The system generates a summary view and diversity indicators for selected subheading pairs, illustrated with "drug therapy" and "therapeutic use".

Conclusions:

  • The developed text mining application offers a novel approach to discovering relationships within biomedical literature.
  • The summary view and diversity indicators provide valuable insights for healthcare professionals and researchers.
  • This tool enhances the utility of MEDLINE data for understanding complex medical relationships, such as drug-disease interactions.
