Resumen
El moco del asma equina (EA) ha alterado los perfiles de proteínas, con una elevación de MUC4 que distingue a los caballos con EA. Estos hallazgos revelan nuevos objetivos para los biomarcadores y tratamientos del asma equina.
Área de la Ciencia:
- Medicina Veterinaria La Medicina Veterinaria es una especialidad de la medicina veterinaria.
- La Proteómica es la Proteómica.
- Enfermedades respiratorias Enfermedades de las vías respiratorias.
Sus antecedentes:
- La hipersecreción de moco es una característica clave del asma equina (AE).
- Los cambios proteómicos en el moco de las vías respiratorias en EA no se comprenden bien.
- La EA se presenta en formas leves a moderadas (MEA) y severas (SEA).
Objetivo del estudio:
- Para analizar la composición proteómica del moco de las vías respiratorias en caballos con SEA, MEA y controles sanos.
- Para identificar las proteínas alteradas en EA y su potencial papel en la enfermedad.
- Explorar posibles biomarcadores específicos del fenotipo y objetivos terapéuticos para EA.
Principales métodos:
- Se utilizó cromatografía líquida cuantitativa libre de etiquetas y espectrometría de masas (LC-MS) para analizar los proteomas del moco.
- Se recogieron muestras de moco de las vías respiratorias de caballos con SEA (n=10), MEA (n=6) y controles sanos (n=8).
- Se identificaron y cuantificaron las proteínas, y se realizaron análisis estadísticos para comparar grupos e identificar cambios significativos.
Principales resultados:
- Se identificaron 2.275 proteínas, incluidas las MUC5AC, MUC5B, MUC1 y MUC4.
- Se observó un aumento significativo de proteínas en SEA (130) y MEA (103) en comparación con los controles.
- La MUC4 aumentó notablemente en ambas formas de EA, se correlacionó con los neutrófilos, y efectivamente distinguió a los caballos asmáticos de los sanos. MUC5AC se elevó en ambas formas de EA, mientras que MUC5B se elevó solo en SEA.
Conclusiones:
- Existen perfiles proteómicos distintos en el moco de las vías respiratorias de los caballos con asma equina.
- Los niveles alterados de proteínas modificadoras del moco sugieren cambios en las propiedades del moco en EA.
- Estos hallazgos proporcionan información sobre la patogénesis de EA y objetivos potenciales para nuevos biomarcadores y terapias.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

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...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

1.4K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...
