Biological Modification in the Brushite Crystallization

MRS Proceedings, 2004
AbstractThe crystallization of brushite has been investigated in the presence of typical ionic biological components, magnesium, fluoride and citrate and a natural protein, osteopontin, using a constant composition method capable of nano-mole sensitivity. While the simple ionic additives, magnesium and fluoride do not have a significant effect, citrate

Modification of flavonoids: methods and influences on biological activities

Critical Reviews in Food Science and Nutrition, 2022
Flavonoids are important active ingredients in plant-based food, which have many beneficial effects on health. But the low solubility, poor oral bioavailability, and inferior stability of many flavonoids may limit their applications in the food, cosmetics, and pharmaceutical industries. Structural modification can overcome these shortcomings to improve

Biologic Response Modification

1993
Biologic response modifiers (BRM) are compounds that modify an immune response, usually enhancing it. They include immune-potentiating bacterial products, chemicals such as polynucleotides, physiologically active molecules such as thymic hormones and interferon, and the true adjuvants, which are administered with the antigen.

Chemical modification of reveromycin A and its biological activities

Bioorganic & Medicinal Chemistry Letters, 2002
Various derivatives of reveromycin A, a novel inhibitor of eukaryotic cell growth, were prepared and their inhibitory effects on both isoleucyl-tRNA synthetase activity and in vitro protein synthesis, and activities on the morphological reversion of src(ts)-NRK cells were assayed.

Surface modification on silicon with chitosan and biological research

Biomedical Materials, 2009
The aim of the present study was to investigate the effect of chitosan modification of silicon (Si) on protein adsorption, cell adhesion and cell proliferation. Chitosan was first immobilized on the Si surface through a (3-aminopropyl)triethoxysilane (APTES) bridge.

Histone modifications dictate specific biological readouts

Journal of Genetics and Genomics, 2009
The basic unit of chromatin is the nucleosomal core particle, containing 147 bp of DNA that wraps twice around an octamer of core histones. The core histones bear a highly dynamic N-terminal amino acid tail around 20-35 residues in length and rich in basic amino acids.

Modification of Biological Activity of Lipopolysaccharide in the Complex with Chitosan

Bulletin of Experimental Biology and Medicine, 2004
In the complex with chitosan, lipopolysaccharide partially lost its ability to induce lymphokines tumor necrosis factor and interleukin-8, but retained immunostimulating properties and increased phagocytic function of macrophages by improving digestion of bacteria.
