Phenolic Profile and Antioxidant Activity of Fractions of Procyanidin-Rich Hawthorn (Crataegus monogyna Jacq.) Bark Extract Separated by Low-Pressure Liquid Chromatography

Molecules
Plant materials rich in proanthocyanidins are fractionated to determine the structure of these compounds and relate it to bioactivity. The aim of this study was to fractionate a procyanidin-rich hawthorn bark extract using low-pressure liquid ...

Antioxidant Activity of Flaxseed Extracts in Lipid Systems

Molecules, 2015
The aim of this work was to compare the antioxidant activity of the extract of flaxseed and its alkaline hydrolysate in two model systems: lipid autoxidation of triacylglycerols of sunflower oil (TGSO)—in a homogeneous lipid media and during β-carotene ...

Edible Coating Chitosan-Acerola to Replace the Sulfites as Preservatives of Fresh Shrimps (Litopenaeus vannamei)

International Journal of Food Science
Melanosis is a chemical reaction based on lipid oxidation, which reduces shrimp shelf-life. This research is aimed at applying chitosan-based coating solutions incorporated with a natural antioxidant (acerola extract) as an antimelanotic material for ...

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.

Effects of Gamma-Irradiation on the Antioxidant Potential of Traditional Bulgarian Teas

Natural Product Communications, 2017
Food irradiation technologies are used to reduce the risk of food borne diseases by eliminating pathogenic microorganisms, prolonging shelf life and reducing storage losses by delaying ripening, germination or sprouting.

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.

High-Temperature Oxidation Behavior of Al_xCoCr_0.5NiPt_0.1 (x = 0.5, 1.0) Multi-Principal Element Alloys at 1100 °C

Metals
The microstructure, phase composition, and high-temperature oxidation behavior of Al0.5CoCr0.5NiPt0.1 and AlCoCr0.5NiPt0.1 multi-principal element alloys (MPEAs) at 1100 °C in air were investigated.

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 ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
