Resumen
Superpropagación
Área de la Ciencia:
- Epidemiología
- Modelado Matemático
- Ciencia de Redes
Sus antecedentes:
- La superpropagación de enfermedades infecciosas, impulsada por diversos comportamientos de contacto, impacta significativamente la dinámica de las epidemias.
- La influencia de la superpropagación a menudo disminuye a medida que una epidemia progresa.
Objetivo del estudio:
- Formular y cuantificar matemáticamente la importancia cambiante de la superpropagación en las epidemias SIR (Susceptible-Infectado-Recuperado).
- Desarrollar métricas para rastrear la dinámica de la superpropagación a lo largo del curso de una epidemia.
Principales métodos:
- Se utilizó un marco de modelado basado en aristas para redes de contacto estáticas.
- Se construyeron tres métricas novedosas: grado medio de nodo infectado, vecinos susceptibles medios de nodos infectados y casos secundarios medios.
- Se analizó el comportamiento temporal de estas métricas de superpropagación.
Principales resultados:
- Los tiempos pico para las tres métricas de superpropagación ocurrieron antes de la mitad del tiempo hasta la prevalencia pico de infección en la población.
- La importancia de la superpropagación disminuye significativamente a medida que las epidemias se acercan a su pico.
Conclusiones:
- Las estrategias de control de enfermedades infecciosas basadas en el contacto son más efectivas cuando se implementan temprano en un brote.
- La intervención temprana es crucial para mitigar el impacto de los eventos de superpropagación.

Transmission-based Precautions I: Contact, Enteric, and Droplets
4.7K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Contact-dependent Signaling
47.6K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Transmission-based Precautions II: Airborne and Protective Environment
2.0K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...
