The ProteinsPlus web service (https//proteins.plus) offers a broad range of tools addressing these challenges. The web interface to the tool collection focusing on protein-ligand interactions has been geared towards easy and intuitive access to a large variety of functionality for life scientists. Since our last publication, the ProteinsPlus web service has been extended by additional services as well as it has undergone substantial infrastructural improvements. A keyword search functionality was added on the start page of ProteinsPlus enabling users to work on structures without knowing their PDB code. The tool collection has been augmented by three tools StructureProfiler validates ligands and active sites using selection criteria of well-established protein-ligand benchmark data sets, WarPP places water molecules in the ligand binding sites of a protein, and METALizer calculates, predicts and scores coordination geometries of metal ions based on surrounding complex atoms. Additionally, all tools provided by ProteinsPlus are available through a REST service enabling the automated integration in structure processing and modeling pipelines. © The Author(s) 2020.

Nevertheless, such outbreaks continue to disrupt the travel industry. This aspect of the IHR has received little attention in the academic literature despite its considerable impact on affected States and commercial activity. This paper outlines the challenges and gaps in knowledge regarding the relationship between outbreaks and the travel sector and discusses the opportunities for further research and policy work to overcome these challenges. METHODOLOGY We conducted a literature review on the relationship between outbreaks and travel restrictions, with a particular focus on the 2014-16 Ebola epidemic in West Africa. This review was complemented by an expert roundtable at Chatham House and further supported by case studies and qualitative interviews. RESULTS Numerous travel stakeholders are affected by, and affect, large-scale infectious disease outber research will also need to take account of COVID-19 travel related issues. © International Society of Travel Medicine 2020.

OBJECTIVES We used model-based compartmental analysis to determine the impact of iron repletion on VA metabolism and kinetics in iron-deficient rats. METHODS At weaning, Sprague-Dawley rats were assigned to either a VA-marginal diet (0.35 mg retinol equivalent/kg) with adequate iron (35 ppm, control group [CN]) or reduced iron (3 ppm, iron-deficient group [ID-]), with an equivalent average body weight for each group. After 5 wk, n = 4 rats from each group were euthanized for baseline measurements of VA and iron indices, and the remaining rats (n = 6 CN, n = 10 ID-) received an intravenous injection of 3H-labeled retinol in an emulsion as tracer to initiate the kinetic study. On day 21 after dosing, half of the ID- rats were switched to the CN diet to initiate iron repletion, referred to as the iron-repletion group (ID+). From the time of dosing, 34 serial blood samples were collected from each rat over a 92-d time course. Plasma tracer and tissue tracee data were fitted to 6- and 4-compartment models, respectively, to analyze the kinetic behavior of VA in all groups. RESULTS Our mathemat
