Physiology of the Gastrointestinal System I: Ingestion and Propulsion

Physiology of the Gastrointestinal System I: Ingestion and Propulsion

The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.

Physiology of the Gastrointestinal System II: Digestion and Absorption

Physiology of the Gastrointestinal System II: Digestion and Absorption

The gastrointestinal (GI) tract, extending from the mouth to the anus, plays a pivotal role in the digestion and absorption of nutrients. This process involves both mechanical and chemical actions facilitated by various enzymes.
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.
In the stomach, a...

Physiology of the Gastrointestinal System III: Elimination

Physiology of the Gastrointestinal System III: Elimination

The gastrointestinal elimination process involves a complex interplay of neural and hormonal mechanisms that coordinate the final waste removal from the body. This intricate operation encompasses the absorption of water and electrolytes, vital for transforming the remaining indigestible food matter into feces. The large intestine is pivotal in water and electrolyte absorption, forming feces from unabsorbed minerals, undigested food, bacteria, bile pigments, and shed epithelial cells. Essential...

Physiological Control of Respiration

Physiological Control of Respiration

Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

A Strategy for the Study of IL-9-Producing Lymphoid Cells in the Nippostrongylus brasiliensis Infection Model

A Strategy for the Study of IL-9-Producing Lymphoid Cells in the Nippostrongylus brasiliensis Infection Model

IL-9-expressing T and ILC2 cells are induced during N. brasiliensis infection, yet their characterization has been largely overlooked in the infected intestine due to their low frequency and differential kinetics. This protocol describes the isolation of these cells from different target organs and confirmation of their identity via flow cytometry at different infection...

Sus antecedentes:

La infección por anquilostomas afecta a más de 400 millones de personas en todo el mundo, causando problemas gastrointestinales, pero su impacto fisiológico no está claro.
La infección controlada por anquilostomas en humanos es una terapia potencial para enfermedades intestinales.

Objetivo del estudio:

Evaluar los efectos de la infección experimental por *Necator americanus* en el tránsito, la motilidad y el pH luminal gastrointestinal en adultos sanos.

Principales métodos:

Se infectó a 10 adultos sanos con larvas de *N. americanus*.
Se midieron los parámetros gastrointestinales utilizando la Cápsula de Motilidad Inalámbrica SmartPill™ en las fases basal, aguda (semana 6) y crónica (semanas 24-48) de la infección.

Principales resultados:

No se observaron cambios significativos en el vaciamiento gástrico, el tránsito intestinal delgado, colónico o de todo el intestino.
Se produjo una reducción transitoria del pH duodenal e intestinal delgado durante la infección aguda, que se normalizó en la fase crónica.
No se detectaron alteraciones significativas en las presiones intraluminales, la frecuencia de contracción o el índice de motilidad.

Conclusiones:

La infección controlada por *N. americanus* en adultos sanos causa una disminución temporal del pH duodenal e intestinal delgado.
La ausencia de alteraciones sostenidas en el tránsito o la motilidad gastrointestinal apoya la seguridad de la infección controlada por anquilostomas para la investigación terapéutica.
