Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

The Role of Poly(Aspartic Acid) in the Precipitation of Calcium Phosphate in Confinement.

Journal of materials chemistry. B, 2013
Many questions remain regarding the formation of ultrathin hydroxapatite (HAP) crystals within the confines of collagen fibrils of bones. These structures form through the interplay of the collagen matrix and non-collagenous proteins, and in vitro ...

Aspartate kinase and the synthesis of aspartate-derived amino acids in wheat

Planta, 1978
Aspartate kinase (EC 2.7.2.4.) has been purified from 7 day etiolated wheat (Triticum aestivum L. var. Maris Freeman) seedlings and from embryos imbibed for 8 h. The enzyme was 50% inhibited by 0.25 mM lysine. In this study wheat aspartate kinase was not inhibited by threonine alone or cooperatively with lysine; these results contrast with those ...

Utilization of Aspartic Acid and Asparagine by Yeast [PDF]

Nature, 1950
MUCH work has been carried out upon the mechanisms whereby yeast is able to utilize nitrogen from amino-acids for its nutrition, and the mechanisms worked out by Ehrlich and Stickland illustrating nitrogen uptake are well known1,2. These and other authors (for example, Thorne3) have been concerned with the value of amino-acids to yeasts simply as ...

INTERACTION OF ASPARTATE AMINOTRANSFERASE WITH AMINO ACIDS [PDF]

Biochemical Journal, 1965
1. The capacity of various amino acids to convert the pyridoxal form of aspartate aminotransferase into the pyridoxamine form has been investigated. 2. Glutamate has the highest converting capacity; aspartate, alpha-aminopimelate, alpha-aminoadipate and other amino acids follow. 3. The converting capacity of the various amino acids assayed is connected

3D Bioprinted Head and Neck Squamous Cell Carcinoma (HNSCC) Model Using Tunicate Derived Nanocellulose (NC) Bioink

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A 3D bioprinted HNSCC model for use in anti‐cancer drug testing is established in proof‐of‐concept. The innovative tunicate‐derived nanocellulose hydrogel proved to be a viable alternative to gelatin‐based hydrogel, offering improved bioprintability for HNSCC model establishment.

Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting

Advanced Healthcare Materials, EarlyView.
Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

Addition of weak acids in electrolytes to prevent osmosis in aqueous organic redox flow batteries

Electrochemistry Communications, 2021
Water transfer issues related to unbalanced ionic strengths in aqueous organic redox flow batteries (AORFBs) are often overlooked. In this work, a simple strategy based on the addition of a weak acid in the negolyte was studied to prevent osmosis in ...
