Tagging and Fusion Proteins

Tagging and Fusion Proteins

Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from the other proteins in the cell. This is achieved by overexpressing the specific gene in a suitable host to produce large quantities of the target protein. A tag or label is recombined with the gene to produce a fusion protein containing the target protein and the tag. The tags on these fusion proteins can then be used for easy detection and...

Labeling DNA Probes

Labeling DNA Probes

DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Structural Classification of Joints

Structural Classification of Joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Area of Science:

Medical Imaging Analysis
Computational Anatomy
Biostatistics

Background:

Image labeling and parcellation are crucial for assessing medical imaging data but are prone to errors from noise, artifacts, and rater subjectivity.
Existing methods combining multiple rater data struggle with small structures, incomplete datasets, and rater unavailability.
Rater variability and uncertainty are inherent challenges in medical image analysis.

Purpose of the Study:

To develop a robust approach for improved image labeling performance, especially for small anatomical structures.
To enable handling of missing data, repeated label sets, and utilization of training/catch trial data.
To facilitate collaborative large-scale dataset construction and robust control of rater heterogeneity.

Main Methods:

A novel robust approach is proposed to address limitations of existing multi-rater data combination techniques.
The method allows numerous raters to label overlapping portions of large datasets.
It robustly controls rater heterogeneity while estimating a single, reliable label set and characterizing uncertainty.

Main Results:

The proposed approach improves estimation performance with small anatomical structures.
It effectively allows for missing data and accounts for repeated label sets.
Enables collaborative construction of large datasets and reduces the impact of rater unavailability.

Conclusions:

The developed method offers a robust solution for medical image labeling, enhancing accuracy and reliability.
It facilitates large-scale collaborative efforts in medical image analysis, overcoming practical data acquisition challenges.
The approach provides a reliable method for estimating a consensus label set and quantifying uncertainty.
