Issues And Trends In Healthcare Delivery System

6.4K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Phylogenetic Trees03:21

Phylogenetic Trees

52.0K
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Model Approaches for Pharmacokinetic Data: Distributed Parameter Models

316
Pharmacokinetic models are mathematical constructs that represent and predict the time course of drug concentrations in the body, providing meaningful pharmacokinetic parameters. These models are categorized into compartment, physiological, and distributed parameter models.
The distributed parameter models are specifically designed to account for variations and differences in some drug classes. This model is particularly useful for assessing regional concentrations of anticancer or...

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

31.9K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Evolutionary Relationships through Genome Comparisons

7.3K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

    Summary

    Managing changes in biomedical ontologies is challenging. Our new framework, Represent, Legitimate and Reproduce (RLR), semi-automates bio-ontology evolution with minimal human input, using category theory and graph transformations.

    Area of Science:

    • Bioinformatics
    • Ontology Engineering
    • Computational Biology

    Background:

    • Current ontology evolution tools lack temporal notations and neglect inter-ontology interactions.
    • Existing methods focus on internal ontology changes, overlooking external relationships.
    • Human factors heavily influence current ontology change management processes.

    Purpose of the Study:

    • To address the inadequacies in current ontology evolution and change management tools.
    • To present a novel agent-based framework for semi-automatic bio-ontology evolution.
    • To emphasize the management of changes in biomedical ontologies, specifically the FungalWeb Ontology.

    Main Methods:

    • Classification of common alterations in popular biomedical ontologies.
    • Development of the Represent, Legitimate and Reproduce (RLR) agent-based framework.
    • Application of category theory and hierarchical graph transformation for change tracking and representation.

    Main Results:

    • Identification and classification of typical changes in biomedical ontologies.
    • A novel framework (RLR) enabling semi-automatic management of bio-ontology evolution.
    • Successful application of RLR to the FungalWeb Ontology with minimal human intervention.

    Conclusions:

    • The RLR framework offers a semi-automatic solution for bio-ontology evolution, reducing human reliance.
    • Category theory and hierarchical graph transformations are effective for managing ontology changes.
    • The RLR framework enhances the management of biomedical ontology evolution and change.
