1. Lactic acid production: extractive fermentation in aqueous two-phase systems
Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

2. Intracellular regulation of TLR signaling Basic mechanisms and importance in intestinal inflammation
Abstract : Toll-like receptors (TLRs) recognize conserved structures on/in microorganisms. The intracellular signalling pathways of TLRs are shared with IL-1R and IL-18R and their activation leads to transcription of proinflammatory cytokines and type-I interferons. READ MORE

4. Effects of Probiotics and Plant Components on Murine Experimental Colitis and Acute Liver Failure
Abstract : Acute liver failure is accompanied by a high rate of bacterial septic complications. High portal level of lipopolysaccharide (LPS) can lead to a pronounced secretion by Kupffer cells of pro-inflammatory mediators which have been shown to be early and important mediators of liver injury.

5. Engineered core : shell nanoparticles: synthesis, characterisation, and biocompatibility studies
Abstract : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. READ MORE
