Resumen
La microbiota intestinal de los perros tanuki jóvenes se vuelve más rica y diversa con la edad, pasando de la dominancia de Bacteroides a Prevotella. Este desarrollo microbiano apoya funciones metabólicas esenciales para la salud animal.
Área de la Ciencia:
- Ciencias Animales
- Microbiología
- Genómica
Sus antecedentes:
- La producción de piel de perro tanuki se está expandiendo, lo que aumenta la necesidad de garantizar la salud animal.
- La microbiota intestinal es crucial para la salud animal, pero su papel en los perros tanuki está poco estudiado.
Objetivo del estudio:
- Caracterizar la composición y función de la microbiota intestinal en perros tanuki en lactancia.
- Proporcionar una base para prácticas científicas de alimentación y manejo en la cría de perros tanuki.
Principales métodos:
- Se recolectaron muestras fecales de ocho perros tanuki a los 14, 21 y 45 días posparto.
- Se analizó la composición de la microbiota utilizando secuenciación de ARNr 16S y herramientas bioinformáticas (LEfSe, Tax4Fun, PICRUSt).
- Se evaluó la diversidad, riqueza y potencial funcional de la microbiota intestinal en diferentes etapas de desarrollo.
Principales resultados:
- La riqueza y diversidad de la microbiota intestinal aumentaron con la edad, alcanzando su punto máximo a los 45 días.
- Firmicutes y Bacteroidetes fueron los filos dominantes.
- Géneros específicos como Bacteroides, Fusobacterium y Prevotella mostraron enriquecimiento temporal.
- El análisis funcional de la microbiota indicó roles en el metabolismo y el procesamiento de información genética, incluido el metabolismo de carbohidratos y aminoácidos.
Conclusiones:
- La composición y función de la microbiota intestinal cambian dinámicamente durante la lactancia en los perros tanuki.
- Estos cambios microbianos están vinculados a procesos metabólicos esenciales beneficiosos para la salud animal.
- Los hallazgos respaldan el desarrollo de estrategias de alimentación específicas para mejorar la supervivencia y el bienestar de los perros tanuki.

01:19Composition of Polyprotic Acid Solutions as a Function of pH
862
Polyprotic acids of the type H2M constitute two ionizable protons. As a result, on titration with a base, they exhibit two equivalence points in the titration curve. During titration, the species H2M, HM−, and M2− will be present in the solution at different points. The fractions of H2M, HM−, and M2− present at the various instances of the titration are denoted by α0, α1, and α2, respectively.

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.

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...

62.4K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Water functions as a solvent accommodating various solutes, which can be categorized under electrolytes and non-electrolytes. Non-electrolytes are usually held together by covalent bonds, restricting them from dissociating in solution, thereby leading to a lack of electrically charged components upon dissolving in water. They are predominantly organic molecules, such as glucose, creatinine, and urea. Electrolytes, on the other hand, are compounds that can break down into ions in water.
