Background & Aims: Aflatoxin M1 is one of the most important toxins present in milk and the product of aflatoxin B1 metabolism in liver microsomes. The aim of this project was to study the aflatoxin M1 adsorption ability of polystyrene-hydroxyapatite nanocomposite. Methods: First, the probability of aflatoxin M1 adsorption by the nanocomposite was evaluated using the HyperChem simulation softwa...

Solid titration was used to explore the solubility isotherms of partially (Srx-HAp, x=1, 5, 10, 40, 60 mol.%) and fully substituted strontium hydroxyapatite (Sr-HAp). Solubility increased with increasing strontium content. No phase other than strontium-substituted HAp, corresponding to the original titrant, was detected in the solid present at equilibrium; in particular, dicalcium hydrogen phos...

Abstract The aim of the study was basic incidence on phenomenon adsorption that occurs at hydroxyapatite/malic acid interface, leading to a change in surface properties hydroxyapatite, Analytical methods used research: X-ray diffraction (XRD) as well by the, adsorption–desorption nitrogen (ASAP), potentiometric titration. specific malic ions hydroxyapatite interface investigated means radioisot...

Abstract Sol–gel derived hydroxyapatite coatings on metallic implants are important to promote their osseointegration and biocompatibility. However, such generally suffer from drawbacks that limit implant longevity. In this study, the sol gel process prepare was optimized used deposit a layer Ti6Al4V. Samples were pretreated by thermal oxidation, sol–gel coating, anodization produce titanium di...

introduction: the purpose of this study was to compare the inhibitory effect of bovine serum albumin (bsa) and hydroxyapatite (ha) on the antibacterial activity of white-colored mta (wmta) against staphylococcus (s.) aureus and streptococcus (s.) mutans after 24 and 72 hours . materials & methods: all materials were prepared according to the manufacturer’s directions immediately before testing....

this article describes the preparation and analysis of nano hydroxyapatite (ha) films on stainless steel 316l through sol-gel technique. the process started with preparation of a nitrate and phosphate sol. after aging the sol for 24 h at room temperature a ss316 substrate was dip-coated and heat-treated at 350 to 450 °c for different times in air. the coating phase and structure on substrate we...

purpose: to report the results of a wrapping technique for hydroxyapatite orbital implants by using mersilen mesh. methods: this study is prospective interventional case series conducted on records of 55 consecutive patients who received a mersilen mesh-wrapped ha orbital implant after enucleation or as a secondary procedure. we recorded results and potiential problem before and after pegging d...

background. many types of toothpastes contain substances that can remineralize initial enamel caries. this study aimed to assess the effect of nano-hydroxyapatite (nha) on microhardness of artificially created carious lesions. methods. in this in vitro study, nha was prepared using sol-gel technique and added to the toothpaste with 7% concentration. a total of 80 extracted sound teeth were coll...

the paper is focused on the formation of hydroxyapatite nanoparticles (hap) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. it is shown that paa, can be incorporated into the individual inverse microemulsion droplets. the m...
