Fluorescence spectroscopy for monitoring rapeseed oil upon heating

open access: yesCzech Journal of Food Sciences, 2004
The aim of this work was to determine the heating effect on the thermo-degradation process of rapeseed oil (RO) by rapid fluorescence method. Reference measurements were carried out by chromatographic methods in order to compare results with those ...

Ichnodiversity and bathymetric range of microbioerosion traces in polar barnacles of Svalbard

open access: yes, 2020
This first comprehensive investigation of microbioerosion traces in polar barnacles addresses two bathymetrical transects from the intertidal down to subtidal water depths in two different carbonate factories in the Svalbard Archipelago: the bay ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Characteristics of heteroatom-containing compounds in Ordovician crude oils from the Lunnan oilfield, Tarim Basin and their implications for secondary alteration and late-stage charging

open access: yesShiyou shiyan dizhi
The Ordovician reservoirs in the Lunnan Oilfield have undergone multiple episodes of secondary alteration and hydrocarbon charging, resulting in highly complex crude oil compositions and molecular geochemical characteristics.

Uncontrolled variables in frying studies: differences in repeatability between thermoxidation and frying experiments

open access: yesGrasas y Aceites, 2007
Palm oil, soybean oil and partially hydrogenated soybean oil were used to define the repeatability of oil degradation under thermoxidation in the absence of food and during the frying of potatoes.

Polar bivalves are characterized by high antioxidant defences

open access: yes, 2005
Inevitably, aerobic life leads to the formation of deleterious reactive oxygen species (ROS) which participate in biomolecule oxidation, hence augmenting biomolecule turnover.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Review of Climate change in the polar regions, by John Turner & Gareth J. Marshall

open access: yes, 2012
In this ambitious, cross-disciplinary volume, British Antarctic Survey scientists John Turner and Gareth Marshall synthesize what is known about climate change in the Arctic and Antarctic and compare the changes that have occurred in the two polar ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
