Biostatistics: Overview

296
Biostatistics plays a crucial role in understanding and analyzing data in healthcare and biology. Biostatisticians conduct experiments, gather evidence, and draw meaningful conclusions using statistical methods and techniques. Different variables form the foundation of biostatistical analysis, allowing researchers to understand and interpret data effectively. These variables are classified into different types, each serving a specific purpose in statistical analysis.
Discrete variables are...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

151
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Genomics

36.6K
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...

Genetic Screens

5.0K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genetics

Background:

  • Data curation is a significant bottleneck in informatics pipelines, particularly for aggregating preclinical study data.
  • Extracting specific data, like gene perturbations and their effects on lesion size and inflammation from mouse studies, is crucial for identifying human atherosclerosis genetic pathways but is labor-intensive.

Purpose of the Study:

  • To develop and evaluate a semi-automated data curation tool to accelerate the extraction of information from preclinical studies.
  • To leverage Natural Language Processing (NLP) for auto-populating a web-based curation form, thereby reducing manual effort.

Main Methods:

  • Development of a semi-automated curation tool employing NLP techniques.
  • Implementation of NLP to auto-populate a web-based form for curator review.
  • Conducting a controlled user study to assess the tool's efficiency and accuracy.

Main Results:

  • The NLP model achieved 70% accuracy on categorical data fields.
  • The semi-automated curation tool reduced task completion time by 49% compared to traditional manual curation.
  • User study validated the tool's effectiveness in accelerating data extraction.

Conclusions:

  • Semi-automated curation tools utilizing NLP can substantially alleviate data extraction bottlenecks in bioinformatics.
  • The developed tool demonstrates significant efficiency gains, accelerating the process of identifying genetic pathways for diseases like atherosclerosis.
  • This approach offers a scalable solution for researchers needing to synthesize data from large volumes of scientific literature.
