A stochastic hierarchical model for low grade glioma evolution.

A stochastic hierarchical model for the evolution of low grade gliomas is proposed. Starting with the description of cell motion using a piecewise diffusion Markov process (PDifMP) at the cellular level, we derive an equation for the density of the transition probability of this Markov process based on the generalised Fokker-Planck equation. Then, a macroscopic model is derived via parabolic limit and Hilbert expansions in the moment equations.

Phytochemicals, Antioxidant and Antiproliferative Properties of L on U937 and CaCo-2 Cells.

L., a medicinal herb from the labiates family, has been reported to have potential benefit in the treatment and prevention of several diseases. In particular its phenolics have demonstrated protective effects on various types of cancer through several mechanisms.

Divergent signaling pathways regulate IL-12 production induced by different species of Lactobacilli in human dendritic cells.

Recent studies have indicated that different strains of Lactobacilli differ in their ability to regulate IL-12 production by dendritic cells (DCs), as some strains are stronger inducer of IL-12 while other are not and can even inhibit IL-12 production stimulated by IL-12-inducer Lactobacilli. In this report we demonstrate that Lactobacillus reuteri 5289, as previously described for other strains of L. reuteri, can inhibit DC production of IL-12 induced by Lactobacilllus acidophilus NCFM.

The regulatory effects of whey retentate from bifidobacteria fermented milk on the microbiota of the Simulator of the Human Intestinal Microbial Ecosystem (SHIME).

Aims: To investigate the effects of whey retentate from Bifidobacteria fermented milk.

Methods And Results: The simulator of the human intestinal microbial ecosystem (SHIME) was used. The composition of the microbiota and its metabolic activities were analysed.

The effects of mesenteric ischemia on ileal colonization, intestinal integrity, and bacterial translocation in newborn piglets.

The effects of mesenteric ischemia on ileal colonization, intestinal integrity, and bacterial translocation (BT) in newborn piglets were investigated in 362-day-old Pietrain piglets. Group I, controls were not operated upon; group II underwent a sham laparotomy; and group III underwent ligation of the mesenteric vessels in the distal ileum. After 3 days, the kidneys, spleens, livers, and ileal segments were harvested for microbial and histologic analyses.
