background: in the last decades, mesoporous silica nanoparticles (msn) are improved for drug delivery, imaging, and biomedical applications due to their special properties such as large surface area, high drug loading capacity, tunable pore size, and modification of surface area by functional groups. objectives: the aim of this study was to evaluate msns as carriers for oral colon-specific and ...

Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...

Among bioactive ceramics, the apatite/wollastonite (A/W) glass ceramic, containing apatite and wollastonite crystals in the glassy matrix, has been largely studied because of good bioactivity and used in some fields of medicine, especially in orthopedics and dentistry. However, medical applications of bioceramic are limited to non-load bearing applications because of their poor mechanical prope...

statement of problem: in order to increase the performance of glass ionomer cement, it is reinforced with metal powders, short fibers, bioceramics and other materials. fluoroapatite (ca10 (po4 )6 f2 ) is found in dental enamel and is usually used in dental materials due to its good chemical and physical properties. objectives: in this study, the effects of the addition of synthesized fluoroapat...
