Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

18.4K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Imaging Biological Samples with Optical Microscopy

8.4K
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...

Flow Cytometry01:23

Flow Cytometry

15.1K
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Two-Dimensional Microscopy in Microbiology

889
Two-dimensional (2D) microscopy encompasses a range of optical techniques that capture images within a single focal plane, offering detailed representations of microscopic structures. These techniques are essential in biological and medical research, enabling the visualization of cellular and subcellular structures with different levels of contrast and specificity.There are several major types of 2D microscopy, each with strengths and applications.Bright-Field MicroscopyBright-field microscopy...

Comparing the Survival Analysis of Two or More Groups01:20

Comparing the Survival Analysis of Two or More Groups

437
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

    • Computational Biology
    • Bioinformatics
    • Data Visualization

    Background:

    • Spatially-resolved omics data provides cellular and spatial insights into tissue function.
    • Comparing large cohorts of this data is crucial for disease research and biomarker discovery.
    • Explorative data analysis is essential due to limited prior knowledge in cohort studies.

    Purpose of the Study:

    • To develop an interactive visual analysis workflow for comparing cohorts of spatially-resolved omics data.

    • To facilitate the identification of cohort-differentiating features and outlier samples.

    Main Methods:

    • Development of an interactive visual analysis workflow.
    • Implementation of multi-level comparison capabilities (cell type abundance, co-localization, tissue images).
    • Continuous consultation with domain experts throughout the development process.

    Main Results:

    • The workflow enables detailed comparison of two spatially-resolved omics data cohorts.
    • It effectively identifies cohort-differentiating features and outlier samples at various analysis stages.
    • Case studies with domain experts across different application areas and data modalities demonstrated its effectiveness.

    Conclusions:

    • The presented workflow offers a powerful tool for comparative analysis of spatially-resolved omics data.
    • It supports explorative data analysis, aiding in disease mechanism and biomarker identification.
    • The workflow's interactive and multi-level approach enhances the understanding of complex biological data in cohort studies.
