Osteoinductivity of polycaprolactone nanofibers grafted functionalized with carboxymethyl chitosan: Synergic effect of β-carotene and electromagnetic field.

This in vitro study developed carboxymethyl chitosan (CMC)-grafted polycaprolactone (PCL) nanofiber scaffolds for bone tissue engineering. It reports mineralization and osteonectin expression in adipose mesenchymal stem cells cultured on the scaffolds, suggesting osteoinductive properties of the grafted CMC. The…

Novel synthesis of MeO (Ni, Cu, La)@Nano-CoO from combination of complexation and impregnation in ultrasonic intervention for low temperature oxidation of toluene under microwave radiation.

This engineering study describes synthesis of nano-metal binary oxide catalysts using complexation and impregnation with ultrasonic intervention for low-temperature catalytic oxidation of toluene under microwave radiation. The La-Co catalyst prepared with ultrasonic intervention is reported to have the best…

[Effects of static magnetic field at different times on the proliferation and differentiation of osteoblasts in vitro].

This in vitro study exposed newborn rat calvarial osteoblasts to a 3.9 mT static magnetic field for varying durations (0–4 hours). The authors report increased cell proliferation and markers of osteoblast differentiation and mineralization versus control, including higher ALP activity, calcium content, and…

[Time effect of sinusoidal electromagnetic field on enhancing the maturation and mineralization of osteoblasts in vitro].

This in vitro study exposed newborn rat calvarial osteoblasts to 50 Hz sinusoidal electromagnetic fields at 1.8 mT for different daily exposure times (0.5–3.0 h). The authors report inhibited osteoblast proliferation at longer exposure times, alongside increased differentiation markers (ALP activity) and…
