Reactivation of hidden-latent infection after doxycycline and streptomycin treatment in mice.

Brucellosis has therapeutic challenges due to 3%-15% relapses/therapeutic failures (R/TF) after antibiotic treatment. Therefore, determining the antibiotic concentration in tissues, the physiopathological parameters, and the R/TF after treatment is relevant. After exploring different antibiotic quantities, we found that a combined dose of 100 µg/g of doxycycline (for 45 days) and 7.

Lysine crotonylation: A challenging new player in the epigenetic regulation of plants.

Lysine crotonylation (Kcr) is a newly discovered post-translational modification, which is structurally and functionally different from the widely studied lysine acetylation. Kcr is found on histones and non-histone proteins, participating in many biological processes through the regulation of chromatin remodeling, metabolism, cell cycle and cellular organization. Among plants, Kcr in histones is not found in the same lysine residues but increases gene expression when it is co-localized with lysine acetylation.
