Reducing Antigenicity and Improving Antioxidant Capacity of β-Lactoglobulin through Covalent Interaction with Six Flavonoids

open access: yesFoods, 2023
β-lactoglobulin (β-LG) is a pivotal nutritional and functional protein. However, its application is limited by its antigenicity and susceptibility to oxidation.

Fundamental media considerations for the propagation of phase-conjugate waves [PDF]

open access: yes, 1991
Rigorous and approximate conditions that need to be satisfied by a propagation medium to enable phase conjugation to occur are derived. It is shown that, in spite of the fact that in general, losses spoil phase conjugation, in the important case of ...

Structural and Biochemical Analysis of OrfG: The VirB8-like Component of the Conjugative Type IV Secretion System of ICESt3 From Streptococcus thermophilus

open access: yesFrontiers in Molecular Biosciences, 2021
Conjugative transfer is a major threat to global health since it contributes to the spread of antibiotic resistance genes and virulence factors among commensal and pathogenic bacteria.

Complex conjugation supermap of unitary quantum maps and its universal implementation protocol

open access: yes, 2019
A complex conjugation of unitary quantum map is a second-order map (supermap) that maps a unitary operator $U$ to its complex conjugate $U^*$. First, we present a deterministic quantum protocol that universally implements the complex conjugation supermap

Electric-field control of interfering transport pathways in a single-molecule anthraquinone transistor [PDF]

open access: yes, 2015
It is understood that molecular conjugation plays an important role in charge transport through single-molecule junctions. Here, we investigate electron transport through an anthraquinone based single-molecule three-terminal device.

Capture of mobile genetic elements following intercellular conjugation promotes the production of ST11-KL64 CR-hvKP

open access: yesMicrobiology Spectrum
Sequence type (ST)11 carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP) can cause life-threatening infections and is therefore of global concern.

Quaternionic Hyperbolic Fenchel-Nielsen Coordinates

open access: yes, 2018
Let $Sp(2,1)$ be the isometry group of the quaternionic hyperbolic plane ${{\bf H}_{\mathbb H}}^2$. An element $g$ in $Sp(2,1)$ is `hyperbolic' if it fixes exactly two points on the boundary of ${{\bf H}_{\mathbb H}}^2$.

Variation on a theme; an overview of the Tn916 / Tn1545 family of mobile genetic elements in the oral and nasopharyngeal streptococci.

open access: yesFrontiers in Microbiology, 2014
The oral and nasopharyngeal streptococci are a major part of the normal microbiota in humans. Most human associated streptococci are considered commensals however a small number of them are pathogenic, causing a wide range of diseases including oral ...

Folic acid conjugated with serum albumin for nano- and submicron delivery systems for applications in therapy and diagnostics [PDF]

open access: yesExploration of Drug Science
Folic acid (FA) residue is a well-known and widely spread targeting ligand, or biovector, used as a component in engineering artificial nanosized and submicron particles (NSPs) to target various cells and treat a variety of diseases that are associated ...

Dominant Bacterial Phyla from the Human Gut Show Widespread Ability To Transform and Conjugate Bile Acids

open access: yesmSystems, 2021
Gut bacteria influence human physiology by chemically modifying host-synthesized primary bile acids. These modified bile acids, known as secondary bile acids, can act as signaling molecules that modulate host lipid, glucose, and energy metabolism and ...
