Diarrhea is considered as an important cause of morbidity and mortality, even though one of the main reasons of death following diarrhea is initiated by dysentery. In recent years, the consumption of probiotics has been proposed for the treatment of infectious diarrhea. Despite most of the studies on probiotics have focused on acute watery diarrhea, few studies in the field of dysentery have found beneficial effects of probiotics. This study is a randomized double-blind clinical trial. The patients were randomly placed into control and case groups...

The administration of probiotics is a promising approach to reduce the prevalence of colon cancer, a multifactorial disease, with hereditary factors, as well as environmental lifestyle-related risk factors. Biogenic polyamines, putrescine, spermidine, and spermine are small cationic molecules with great roles in cell proliferation and differentiation as well as regulation of gene expression. Ornithine decarboxylase is the first rate-limiting enzyme for polyamine synthesis, and upregulation of ornithine decarboxylase activity and polyamine metabolism has been associated with abnormal cell proliferation...

Nisin is a small antimicrobial peptide produced by several subset strains of Lactococcus lactis. To improve nisin yield in the producer L. lactis LS01, we proposed a successive fusion of nisA with nisRK and nisFEG into a single shuttle expression vector pMG36e under the control of the native strong constitutive promoter p32. Subsequently, the recombinant vectors were transplanted into the producer cell through electroporation. Nisin productivity was determined through sodium dodecyl sulfate-polyacrylamide gel electrophoresis and bioactivity assays...

This work is concerned with the role of evolutionary conserved substances, neurotransmitters, and neurohormones, within the complex framework of the microbial consortium-immune system-nervous system axis in the human or animal organism. Although the operation of each of these systems per se is relatively well understood, their combined effects on the host organism still await further research. Drawing on recent research on host-produced and microbial low-molecular-weight neurochemicals such as biogenic amines, amino acids, and short-chain fatty acids (SCFAs), we suggest that these mediators form a part of a universal neurochemical "language...

Bifidobacterium is an important probiotic bacterium and extensively applied to functional food. Its survival is strongly affected by the heat-shock process during manufacture. Acclimation is thought to be able to enhance Bifidobacterium's resistance to heat stress; however, so far little is known about the protein expression changes underlying the adaptation process. In this study, the appropriate acclimation temperature for Bifidobacterium longum was determined as 43 °C, and 2-dimensional gel electrophoresis-based proteomic analysis was performed to reveal the protein changes in expression levels behind heat acclimation...
