Genomics02:02

Genomics

37.0K
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...

Genome Annotation and Assembly03:36

Genome Annotation and Assembly

19.3K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Classification of Illness01:17

Classification of Illness

7.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Ogive Graph01:07

Ogive Graph

5.8K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

Area of Science:

  • Genetics and Genomics
  • Bioinformatics
  • Medical Informatics

Background:

  • Rare diseases (RDs) present challenges due to low prevalence and limited data for research.
  • Advancements in big data analytics, particularly in genetics and genomics, have significantly improved the understanding of RDs.
  • A growing body of RD-related publications offers potential for scientific insight and further investigation.

Purpose of the Study:

  • To systematically analyze, semantically annotate, and categorize RD-related PubMed articles.
  • To integrate semantic annotations into a knowledge graph (KG) for enhanced data accessibility.
  • To demonstrate the scientific utility of the KG for rare disease research through case studies.

  • Systematic analysis of RD-related publications from PubMed.
  • Semantic annotation and scientific categorization of analyzed articles.
  • Integration of annotations into a Neo4j-hosted knowledge graph using a predefined data model.

Main Results:

  • A comprehensive knowledge graph was constructed from RD-related literature.
  • The KG successfully integrated semantic annotations, enabling structured data exploration.
  • Case studies demonstrated the KG's capability to reveal scientific contributions in rare disease research.

Conclusions:

  • The developed knowledge graph provides a valuable resource for accessing and understanding the scientific landscape of rare diseases.
  • The study highlights the potential of leveraging big data analytics and knowledge graphs to overcome data limitations in rare disease research.
  • Future work includes expanding the KG with more publications and diverse data resources to further support RD investigation.
