Abstract: The effect of inoculation with a probiotic strain, Lactobacillus casei ŁOCK 0900, on selected parameters related to proteolysis of dry-cured pork loins during ageing was studied. Moisture content decreased significantly (p<0.05) throughout ageing, accompanied by a progressive reduction in water activity. The total nitrogen (TN) content increased during ageing with no effect (p<0.05) of inoculation with L. casei on its level. The greatest increase in non-protein nitrogen (NPN) content during ageing occurred...

Abstract: The human intestine is colonised by 1013 to 1014 micro-organisms, the vast majority of which belong to the phyla Firmicutes and Bacteroidetes. Although highly stable over time, the composition and activities of the microbiota may be influenced by a number of factors including age, diet and antibiotic treatment. Although perturbations in the composition or functions of the microbiota are linked to inflammatory and metabolic disorders (e.g. inflammatory bowel diseases, irritable bowel syndrome and obesity), it...

Abstract: The gut microbiota comprises a large and diverse range of microorganisms whose activities have a significant impact on health. It interacts with its host at both the local and systemic level, resulting in a broad range of beneficial or detrimental outcomes for nutrition, infections, xenobiotic metabolism, and cancer. The current paper reviews research on the role of intestinal microflora in colorectal cancer development. Especially a protective effect of beneficial bacteria and probiotics on the risk of cancer...

Abstract: The retention of p-cresyl sulfate (PCS), the prototype of protein-bound uremic toxins that is produced by the gut microbiota and normally excreted by the kidney, may contribute to the development of insulin resistance in patients with chronic kidney disease. In a recent study, we demonstrated in mice, as in cultured muscle cells, that PCS interferes with intracellular insulin signaling pathways and triggers insulin resistance. The treatment of CKD mice with a prebiotic that reduces the intestinal production...

Abstract: Probiotic use as capable preventive and therapeutic strategy in different diseases varying from allergic to autoimmune disease (AD) has been recently reported. Three interacting factors including an aberrant intestinal microbiota, a "leaky" intestinal mucosal barrier, and altered intestinal immune responsiveness have been suggested to be able to create a "perfect environment" for AD development. Regulation of intestinal microflora composition by probiotics offers the possibility to influence the development...
