The effect of electromagnetic fields on survival and proliferation rate of dental pulp stem cells.

This in vitro study tested whether 50 Hz extremely low-frequency electromagnetic fields (0.5 or 1 mT) affect human dental pulp stem cell survival and proliferation. Using MTT and DAPI assays after 7 days of exposure (20 or 40 min/day), all exposed groups reportedly showed higher viability/proliferation than controls.…

Extremely low frequency variable electromagnetic fields affect cancer and noncancerous cells in vitro differently: Preliminary study.

This in vitro study exposed cancer (U87-MG; 143B) and noncancerous (BJ; HEK) cells to extremely low frequency electromagnetic fields under varying frequencies (2–60 Hz), waveforms, and exposure durations, with sham controls. Cell viability was assessed using an MTT assay. The authors report that cancer and…

Biodegradable, pH-sensitive chitosan beads obtained under microwave radiation for advanced cell culture.

This in vitro study describes microwave-assisted, green-chemistry synthesis of pH-sensitive chitosan beads crosslinked with a glutamic acid/1,5-pentanodiol mixture and optionally modified with Tilia platyphyllos extract. The beads were characterized (FT-IR, SEM), tested for swelling, pH sensitivity, antioxidant…
