Cross‐border reciprocal bartering in public–private tetradic networks

open access: yesDecision Sciences, EarlyView.
Abstract Under the background of semiconductor and vaccine shortages during COVID‐19‐driven supply chain disruptions, this article adopts a multimethodological approach to investigate strategic solutions for cross‐border scarce goods bartering in a public–private (P–P) tetradic reciprocal network, which involves two pairs of P–P collaborative dyads ...

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

open access: yesThe FEBS Journal, EarlyView.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.
