Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.8K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Issues And Trends In Healthcare Delivery System

6.3K
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...

Ethical Standards I01:25

Ethical Standards I

1.6K
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

2D NMR: Overview of Homonuclear Correlation Techniques

708
Homonuclear correlation spectroscopy (COSY) is a powerful technique used in Nuclear Magnetic Resonance (NMR) spectroscopy to study the correlations between nuclei of the same type within a molecule. It provides information about scalar couplings between adjacent nuclei, which helps determine connectivity and structural information. There are several COSY variants, each with its unique strengths and experimental parameters.
COSY90 is the standard two-dimensional (2D) COSY experiment that...

Proteomics01:33

Proteomics

9.9K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Área de la Ciencia:

  • Bioinformática
  • Biología Computacional
  • Privacidad de Datos

Sus antecedentes:

  • La investigación bioinformática a gran escala requiere colaboración interinstitucional.
  • Los métodos existentes de colocalización de datos son ineficientes y plantean problemas de privacidad.
  • El análisis seguro de conjuntos de datos sensibles distribuidos es un desafío crítico.

Objetivo del estudio:

  • Desarrollar un marco de analítica federada que preserve la privacidad para el análisis bioinformático seguro entre instituciones.
  • Permitir cálculos estadísticos sobre datos cifrados sin transferencia de datos brutos.

Principales métodos:

  • Se implementó un marco de analítica federada que utiliza métodos criptográficos para el cálculo seguro sobre datos cifrados.
  • Se realizaron análisis en conjuntos de datos distribuidos sin colocalización de datos.

Principales resultados:

  • Se validó el marco calculando puntuaciones de riesgo poligénico y realizando metaanálisis en cohortes del mundo real.
  • Se logró una precisión superior al 99,9% en comparación con los análisis de texto plano.
  • Se demostró un rendimiento de tiempo de ejecución escalable con el aumento del tamaño de los datos y los sitios participantes.

Conclusiones:

  • El marco propuesto ofrece una solución factible y segura para aplicaciones bioinformáticas prácticas que involucran datos sensibles y distribuidos.
  • La analítica federada se puede aplicar eficazmente al análisis de datos genómicos y de salud a gran escala preservando la privacidad.
