Probiotics and Human Health

Probiotics exhibit an inhibitory effect on pathogens, help prevent chronic intestinal inflammatory diseases or atopic syndromes, and support the immune system.

Peroxisome proliferator-activated receptor-gamma-independent repression of collagenase gene expression by 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid and prostaglandin 15-deoxy-delta(12,14) J2: a role for Smad signaling.

Matrix metalloproteinases (MMPs) degrade extracellular matrix components, and overexpression of these enzymes contributes to tissue destruction in arthritis. Of particular importance are the collagenases, MMP-1 and MMP-13, which have high activity against the interstitial collagens in cartilage. In this study

Histone deacetylase inhibitors sodium butyrate and valproic acid delay spontaneous cell death in purified rat retinal ganglion cells.

Julia Biermann et al.

Molecular vision, 17, 395-403 (2011-02-12)

Histone deacetylase inhibitors (HDACi) have neuroprotective effects under various neurodegenerative conditions, e.g., after optic nerve crush (ONC). HDACi-mediated protection of central neurons by increased histone acetylation has not previously been demonstrated in rat retinal ganglion cells (RGCs), although epigenetic changes

Separation of two conjugates of clofibric acid (CPIB) found in the urine of subjects taking clofibrate.

E M Faed et al.

Clinical and experimental pharmacology & physiology, 5(2), 195-198 (1978-03-01)

1. Two main conjugates of CPIB (2-[chlorophenoxy]-2-methylpropionic acid) are present in the urine of subjects taking clofibrate. The metabolites can be separated by thin-layer chromatography (TLC). 2. Both conjugates are hydrolysed by dilute alkali, but only one is hydrolysed by
