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 ...

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 ...

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.

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 ...

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.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

EFFECT OF STORAGE AND HEAT ON CHEMICAL-PHYSICAL PROPERTIES AND ANTIMICROBIAL ACTIVITY OF BEE HONEY [PDF]

Journal of Productivity and Development, 2019
Heat treatment and sorage of bee honey caused an increase of the HMF that exceeded greatly the allowance limit (level),meanwhile it decreased the diastase number.
