Scaling in DNA unzipping models: denaturated loops and end-segments as branches of a block copolymer network

, 2002
For a model of DNA denaturation, exponents describing the distributions of denaturated loops and unzipped end-segments are determined by exact enumeration and by Monte Carlo simulations in two and three dimensions.

Alkaline Denaturation of Nucleohistone [PDF]

European Journal of Biochemistry, 1972
The ultraviolet spectral change at 245 nm of tyrosine residues in histones in alkaline solution was studied. The difference spectrum of histones between alkaline and neutral solution yields an absorption maximum at 242 nm. However, the influence of configurational changes of backbone structure of histones in alkaline solution, results in the true peak ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

Advanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.
