Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Evolution of New Traits in Microbes

Evolution of New Traits in Microbes

Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...

Gene Duplication and Divergence

Gene Duplication and Divergence

The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.

Evolutionary Psychology

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the human psyche...

Medical Informatics
Computational Biology
Clinical Data Management

Background:

Managing temporal aspects of neurodegenerative disorders is crucial due to their progressive nature and variable presentations.
Existing patient case reports often lack detailed temporal information, hindering comparative analysis.
Tools for describing the evolution of phenotype manifestations are vital for early disease recognition and optimized diagnosis.

Purpose of the Study:

To demonstrate the utility of representing patient case reports as semantically annotated temporal clinical manifestation sequences.
To develop novel techniques for querying and matching these sequences to infer phenotype evolution patterns.
To aid in clinical studies by automatically generating insights into disease progression.

Main Methods:

Representing patient case reports as sets of time-stamped clinical manifestations, annotated with a phenotype ontology.
Developing algorithms to query and match temporal manifestation sequences across multiple patient cases.
Applying the method to 25 patient cases of cerebrotendinous xanthomatosis.

Main Results:

Successfully generated five distinct phenotype evolution patterns from the patient data.
The automated analysis achieved a precision of 93% and a recall of 70% when evaluated against existing study conclusions.
Demonstrated the feasibility of inferring disease progression patterns from limited temporal data.

Conclusions:

Representing patient data as temporal sequences with semantic and time-based annotations is effective for analyzing neurodegenerative disorder progression.
Automated pattern inference from these sequences can significantly enhance clinical studies and diagnostic support.
The developed techniques offer a valuable tool for understanding complex disease trajectories.
