Abstract
Biogenic amines in the gastrointestinal tract are important metabolites of dietary protein and amino acids with the help of gut digestive enzymes and microbes, which play a crucial role in the regulation of intestinal functions, including digestion, absorption, and local immunity. However, high concentrations of biogenic amines can induce adverse reactions and are harmful to animal's health. Therefore, it is crucial to have a clear understanding of how different biogenic amines interact with a body's intestinal function signaling pathways and to monitor the content of biogenic amines in the gastrointestinal tract. And in turn, the proper concentration of dietary protein and balanced amino acids for humans and livestock could be given. Though numerous methods have been developed and improved for the detection of biogenic amines in foods or wines much less attention has been paid directly to the determination of amine levels in the gastrointestinal tract. In this article, we mainly focus on the interaction of amines with the intestinal function signaling pathway and the broad impacts on animal physiology, and our modified method to accurately and quickly detect the biogenic amines in the digesta of an animal intestine.
Keywords: Biogenic amines, gastrointestinal tract, modulation, signaling pathway, HPLC.

Nutrition and Metabolism in Musculoskeletal Diseases
The musculoskeletal system consists mainly of cartilage, bone, muscles, tendons, connective tissue and ligaments. Balanced metabolism is of vital importance for the homeostasis of the musculoskeletal system. A series of musculoskeletal diseases (for example, sarcopenia, osteoporosis) are resulted from the dysregulated metabolism of the musculoskeletal system. Furthermore, metabolic diseases (such ...read more
Protein Folding, Aggregation and Liquid-Liquid Phase Separation
Protein folding, misfolding and aggregation remain one of the main problems of interdisciplinary science not only because many questions are still open, but also because they are important from the point of view of practical application. Protein aggregation and formation of fibrillar structures, for example, is a hallmark of a ...read more
