Medulla and Gut

Neurochemistry and anatomy of the ventral medulla

The relationship between the anatomy and neurochemistry of neurons in the ventral medulla oblongata in regions that is responsible for cardiovascular, airways, and respiratory regulation was investigated. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM) were made throughout the ventral medulla in anesthetized rats. Arterial blood pressure, sympathetic nerve activity and phreni...

Heterogeneity of chromogranin A-derived peptides in bovine gut, pancreas and adrenal medulla.

Chromogranin A is produced in many endocrine cell types, and is widely used as a marker in endocrine-cell pathology and secretory-cell biology. There is some evidence that it may be proteolytically processed to yield the putative pancreatic regulatory peptide, pancreastatin, and, in order to characterize the relevant pathways in gastrointestinal and pancreatic endocrine cells, we have used, in ...

Psychobiotics and Brain-Gut Microbiota Axis

Fermented foods containing probiotic bacteria have been used for many years to improve the health or treatment of some diseases. Nowadays, the Therapeutic properties of probiotics are becoming more and more obvious to everyone, insofar as in recent years, more attention has been paid to the potential relation between gut microbiota and mental health. Several studies have shown that intestinal m...
