topicMannan Oligosaccharides Gut Health Randomized Trial
claimHeat stress poses serious threats to human and animal health by inducing systemic inflammation, oxidative stress, and intestinal barrier damage, yet the potential of functional food components in mitigating heat stress-associated health impairments remains insufficiently explored.

claimThe results demonstrated that both BG and MOS effectively attenuated heat stress-induced body weight loss, elevated liver index, and systemic inflammatory responses, significantly reduced serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor- α (TNF-α), and heat shock protein 70 (HSP70), and restored antioxidant enzyme activity.

topicMannan Oligosaccharides Gut Health Randomized Trial
claimWhile the degradation of manno-oligosaccharides has been previously studied, interest in bacterial mannobiose epimerases and mannoside phosphorylases is increasing because these enzymes provide a replacement for bacterial phosphotransferase systems as part of synthetic biology applications.
