Probiotics and immunity: provisional role for personalized diets and disease prevention.

There is great interest in the interaction between diet and immune system and concomitantly in the potential of probiotic bacteria, especially given recent advances in understanding of gut microbiota effects on health in the context of microbiome research. Following our recent study on bacterial wall elasticity as a predictive measure of phagocytic cellular reactions and related outcomes, a question was raised regarding the scope of the application of these findings in various medical conditions in the context of predictive, preventive, and personalized medicine (PPPM). This summarizing review of the data describes the contributions, both observed and potential, of probiotics to the gut-brain axis and various medical conditions, including immune and atopic states, metabolic and inflammatory diseases-including liver disease and diabetes mellitus-cancer, and more.

The age-related dynamics of chromosomal instability and germination capacity of welsh onion (Allium fistulosum L.) seeds have been studied under two different storage temperatures during six years after harvesting. Seeds that were kept at the room temperature (14-28 degrees C) during 6 years of storage have lost their germination capacity.

Effect of cord blood cells on interferonogenesis and effector cells of immune system.

Human cord blood cells were shown to produce interferon-alpha- and -gamma in vitro, both spontaneously and following adequate induction. Transplantation of human blood cord cells to mice led to endogenous interferonogenesis activation, serum interferon levels as well as interferon-alpha and interferon-gamma synthesis by activated peripheral blood leucocytes becoming higher. The maximal interferon accumulation in murine blood sera following transplantation did not coincide with interferonogenesis dynamics observed due to the effect of standard early and late interferon inducers - poly I:C and ridostin, respectively.
