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.

Enduring Behavioral Effects Induced by Birth by Caesarean Section in the Mouse.

Livia H Morais et al.

Current biology : CB, 30(19), 3761-3774 (2020-08-22)

Birth by Caesarean (C)-section impacts early gut microbiota colonization and is associated with an increased risk of developing immune and metabolic disorders. Moreover, alterations of the microbiome have been shown to affect neurodevelopmental trajectories. However, the long-term effects of C-section

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.

Kimberlee S Mix et al.

Molecular pharmacology, 65(2), 309-318 (2004-01-27)

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
