In this work, we report high biological performance of silicon substituted nano hydroxyapatite (nHA) prepared by immersion of calcium phosphate and sodium silicate as precursors in Simulated Body Fluid (SBF) solution for 24, 36, 48 and 72 hrs at 37°C. Characterization and chemical analysis of the synthesized powders were performed by Fourier transform, infrared spectroscopy (FT-IR), X-ray powde...

conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...

objective: this study aimed to evaluate the levels of two oxidative stress (os) markers including lipid peroxide (lpo) and total antioxidant capacity (tac) in both serum and follicular fluid (ff) of women with endometriosis after puncture. materials and methods: in this cross-sectional study, a total number of sixty-three women younger than 40 years old with laparoscopy (gold standard for endom...
