Dynamics of ion-phosphate lattice of DNA in left-handed double helix form [PDF]

open access: yesUkr. J. Phys. V. 58, 554-562 (2013), 2013
The conformational vibrations of Z-DNA with counterions are studied in framework of phenomenological model developed. The structure of left-handed double helix with counterions neutralizing the negatively charged phosphate groups of DNA is considered as the ion-phosphate lattice. The frequencies and Raman intensities for the modes of Z-DNA with Na+ and

Improving Egg Quality in Tropical Environments: Assessing the Maize Meal Replacement by Wheat Bran and Soybean Oil in Laying Hen Diets

open access: yesVeterinary Medicine and Science, Volume 11, Issue 4, July 2025.
This study demonstrates that replacing maize meal with wheat bran (WB) in laying hen diets, with or without soybean oil, maintains egg quality while enhancing economic performance through increased profitability and contribution margins. The results suggest that WB can be effectively utilized in monogastric animal feeding systems.

Facile immobilization of pyridoxal 5′-phosphate using p-diazobenzoyl-derivatized Sepharose 4B

open access: yesResults in Chemistry, 2023
Pyridoxal 5′-phosphate (PLP) is a ubiquitous and versatile cofactor utilized by numerous enzymes involved in amino acid biosynthetic pathways. Immobilized PLP is a valuable tool to isolate unknown PLP-dependent enzymes in nature or to perform in vitro ...

Synergistic Role of Transition Metals and Polyanionic Frameworks in Phosphate-Based Cathode Materials for Sodium-Ion Batteries [PDF]

open access: yesarXiv
Ongoing research in the area of advanced cathode materials for sodium-ion batteries (SIBs) is expected to reduce reliance on lithium-ion batteries (LIBs), providing more affordable and sustainable energy storage solutions. Polyanionic compounds have emerged as promising options due to their stable structure and ability to withstand high-voltage ...

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...
