1. Egg white proteins from the eggs of domestic chicken (Gallus gallus), turkey (Meleagris gallopavo), duck (Anas platyrhynchos) and goose (Anser anser) were analysed in order to compare the antimicrobial activity of these products. 2. Albumen from each species was sampled and analysed by SDS-PAGE

The purpose of this study was to establish a method for determining the bacteriolytic activity after separation of lysozyme-binding proteins from egg white. Lysozyme-binding proteins such as ovotransferrin and ovalbumin were separated by non-denaturing two-dimensional electrophoresis (2DE) and

BACKGROUND White spot lesions are an undesired side effect of fixed orthodontic treatment. The objective of this research was to develop an antibacterial resin-modified glass ionomer cement (RMGIC) containing nanoparticles of silver (NAg) for prevention of white spot lesions. METHODS NAg was

Wine contains a number of biologically active compounds with beneficial effects on human health. The antibacterial action of commercial red and white wines against oral streptococci responsible for caries development and against S. pyogenes responsible for pharyngitis was studied. Its postcontact

Hen egg white is an original biological fluid in which major proteins have been widely studied, unlike the minor components. In this study, two-dimensional electrophoresis associated with mass spectrometry enabled the separation of 69 protein spots and their matching with major proteins, which were

Bacterial adhesion and proliferation on surfaces are a challenge in medical and industrial fields. Here, a simple one-step technique is reported to fabricate self-cleaning and bactericidal surfaces. White, blue, and violet paints were produced using titanium dioxide nanoparticles,

Two structurally distinct forms of eggwhite lysozyme (EC 3.2.1.17) are known. The egg white of some species contains both of these forms, while the egg white of other species appears to contain only one or the other of them. We have immunological and electrophoretic evidence that the chicken, which

Chicken egg white lysozyme exhibits antimicrobial activity against both Gram-positive and Gram-negative bacteria. Fractionation of clostripain-digested lysozyme yielded a pentadecapeptide with antimicrobial activity but without muramidase activity. The peptide was isolated and its sequence found to

UNASSIGNED This study was conducted to assess the antiplaque efficacy of a mouthwash containing white tea. It also assessed the antibacterial properties of white tea against Prevotella intermedia (Pi), Porphyromonas gingivalis (Pg), and Aggregatibacter actinomycetemcomitans (Aa) in

Crystal violet (CV) was incorporated into acrylic latex to produce white-light-activated antimicrobial paint (WLAAP). Measurement of the water contact angle of the WLAAP showed that the water contact angle increased with increasing CV concentration. In a leaching test over 120 h, the amount of CV

OBJECTIVE White spot lesions are the most undesired side-effect of fixed orthodontic treatments. The objectives of this study were to combine nanoparticles of silver (NAg) with 2-methacryloyloxyethyl phosphorylcholine (MPC) to develop a modified resin-modified glass ionomer cement (RMGI) as

Peptide fragments possessing antimicrobial activity were obtained by protease digestion of goose egg white lysozyme. Digested peptide purified from RP-HPLC which showed no lysozyme activity exhibited bactericidal activity toward Gram-negative and Gram-positive bacteria. LC/MS-MS and automated Edman
