background and aims. lysozyme and lactoferrin are salivary proteins which play an important role in innate defense mechanisms against bacteria. this study investigated the association of salivary lysozyme and lactoferrin concentrations with early childhood caries (ecc). materials and methods. this study was carried out on 42 healthy children (age range, 36 to 71 months), of whom 21 were caries ...

Pathogens represent a universal threat to other living organisms. Most organisms express antimicrobial proteins and peptides, such as lysozymes, as a protection against these challenges. The nematode Caenorhabditis elegans harbours 15 phylogenetically diverse lysozyme genes, belonging to two distinct types, the protist- or Entamoeba-type (lys genes) and the invertebrate-type (ilys genes) lysozy...

lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, gly...

effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...

Hydrogels exhibiting selectivity towards lysozyme were produced by metal-ion assisted-imprinting technology. A metal-chelate monomer N-vinyl-2-pyrrolidone is pre-assembled with the template molecule via assistance of Cu(II) ions and co-polymerized 2-hydroxyethyl methacrylate. Lysozyme imprinted hydrogels characterized Fourier transform infrared spectroscopy, swelling tests, scanning electron mi...

lysozyme is considered as part of the innate immune system. it has stimulated considerable interest as a natural food preservative. lysozyme has been shown to be effective in preserving a variety of foods such as fresh fruits and vegetables, meats, seafood and wine, for which many japanese patents have been granted. the relatively high thermal stability of lysozyme also makes it attractive for ...

In recent years, several oconjugation protocols have been developed to improve the functional properties of the enzyme lysozyme. In this study, the optimum conditions of lysozyme – oxidized inulin conjugation and functional properties of the modified lysozyme were investigated. Initially, inulin (MW about 25 kDa) was oxidized by periodate to provide the reactive carbonyl groups  to attach to am...

PURPOSE To evaluate the interfacial properties of ex vivo tear lipid multilayers with controlled and varying thickness. The influence of lysozyme and surfactant-containing multipurpose lens care solution (MPS) on interfacial rheology of lipids and mixed lipid-protein films were studied. METHODS Lipids were extracted from lotrafilcon A lenses worn continuously for 1 month. Interfacial properti...

b ackground: in this study the concentration of lysozyme in blood plasma of  microtus agrestis, clethrinomys glareolus , apodemus sylvaticus, bk rats and outbred white mice before and after infection with culture forms of trypanosoma microti, t, evotomys, t. grosi, t. lewisi and t. musculi respectively was measured. m ethods: blood samples of rodents, microtus agrestis, clethrionomys glareolus,...
