This phenotype can be complemented by reintroduction of the 3,4-DHBP synthase domain alone. Our results indicate that, in Bradyrhizobium ORS285, the RibBX protein is not essential for riboflavin biosynthesis under free-living conditions and we hypothesize that its activity is needed to sustain riboflavin biosynthesis under certain symbiotic conditions.[Formula see text] Copyright © 2021 The Author(s).

Novel prognostic and/or predictive biomarkers are urgently needed to improve patient management. Alpha-fetoprotein is a well-established and widely used biomarker for hepatocellular carcinoma. However, diagnostic accuracy of static alpha-fetoprotein values is limited and the clinical potential is a matter of ongoing scientific discussion. We here evaluated the prognostic impact of pre-treatment static and dynamic alpha-fetoprotein variables on overall survival of hepatocellular carcinoma patients in a Western cohort. Patients with confirmed hepatocellular carcinoma (  = 809) treated at the Johannes Gutenberg-University Mainz between 1998 and 2014 and two available pre-treatment alpha-fetoprotein-values (AFP-slope) were retrospectively analysed. Clinico-pathological baseline parameters, pre-treatment static values and AFP-slope were assessed. Prognostic impact was determined by Kaplan-Meier analyses and Cox regression models. High sl vein tumour thrombosis. Static and dynamic alpha-fetoprotein variables prior to therapy are predictive for overall survival of hepatocellular carcinoma patients. Addition of AFP-slope to established prognostic parameters might improve prognostic classification for
