PathwayNexus: a tool for interactive metabolic data analysis.

Motivation: High-throughput omics methods increasingly result in large datasets including metabolomics data, which are often difficult to analyse.

Results: To help researchers to handle and analyse those datasets by mapping and investigating metabolomics data of multiple sampling conditions (e.g.

APL@voro-interactive visualization and analysis of cell membrane simulations.

Summary: Molecular dynamics (MD) simulations of cell membranes allow for a better understanding of complex processes such as changing membrane dynamics, lipid rafts and the incorporation/passing of macromolecules into/through membranes. To explore and understand cell membrane compositions, dynamics and processes, visual analytics can help to interpret MD simulation data. APL@Voro is a software for the interactive visualization and analysis of cell membrane simulations.

A cross-cultural perspective on feeling good in the context of foods and beverages.

The aim of the present research was to explore consumers' conceptualization of feeling good in relation to food and beverages from a cross-cultural perspective. Participants from 14 countries across 5 continents and covering 10 languages (N = 8325) responded to an online survey including word association and free listing tasks related to feeling good in the context of food and beverages. Results were analyzed using inductive coding: a list of main codes was generated in English for each of the tasks, after which native speakers for each language coded the responses.

N-nitrate and S-sulfate isotopic fractionation reflects electron acceptor 'recycling' during hydrocarbon biodegradation.

The analysis of stable carbon isotopes for the assessment of contaminant fate in the aquifer is impeded in the case of petroleum hydrocarbons (TPH) by their chain length. Alternatively, the coupled nitrogen-sulfur-carbon cycles involved into TPH biodegradation under sulfate- and nitrate reducing conditions can be investigated using nitrogen (δN) and sulfur (δS) isotopic shifts in terminal electron acceptors (TEA) involved in anaerobic TPH oxidation. Biodegradation of a paraffin-rich crude oil was studied in anaerobic aquifer microcosms with nitrate (NIT), sulfate (SUL), nitrate plus sulfate (MIX) and nitrate under sulfate reduction suppression by molybdate (MOL) as TEA.
