Properties of vegetable oils modified by hydrogenation, interesterification and fractionation

Grasas y Aceites, 1992
The advent of techniques of chemical processing (hydrogenation and interesterification) and physical processing (fractionation) provides the manufacturer the capacity of modifying one or many physicochemical properties of an oil or fat.

Quantifying mineral-associated organic matter in wetlands as an indicator of the degree of soil carbon protection

Geoderma, 2023
As atmospheric carbon (C) concentrations increase, so too has interest in understanding the mechanisms that preserve C within the soil organic matter (SOM).

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Carbon isotope effects in the sorption of chlorinated ethenes on biochar and activated carbon

Heliyon, 2023
As an alternative to activated carbon, biochar is a promising, environmentally friendly sorbent that can be used to remove organic groundwater pollutants, such as chlorinated ethenes (CEs).

Air–snow transfer of nitrate on the East Antarctic Plateau – Part 1: Isotopic evidence for a photolytically driven dynamic equilibrium in summer [PDF]

Atmospheric Chemistry and Physics, 2013
Here we report the measurement of the comprehensive isotopic composition (δ15N, Δ17O and δ18O) of nitrate at the air–snow interface at Dome C, Antarctica (DC, 75°06' S, 123°19' E), and in snow pits along a transect across the East Antarctic ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Nitrogen fractionation in external galaxies [PDF]

, 2019
In star-forming regions in our own Galaxy, the 14N/15N ratio is found to vary from ~100 in meteorites, comets, and protoplanetary discs up to ~1000 in pre-stellar and star-forming cores, while in external galaxies the very few single-dish large-scale ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Comparison of Fractionation Methods for Soil Organic Matter 14C Analysis [PDF]

, 1996
14C measurements provide a useful test for determining the degree to which chemical and physical fractionation of soil organic matter (SOM) are successful in separating labile and refractory organic matter components.
