Dimethyl sulfoxide affects the viability and mineralization activity of apical papilla cells in vitro.

Dimethyl sulfoxide (DMSO) is widely used as an adjuvant in dissolving insoluble compounds in an aqueous medium; however, it can induce significant molecular changes in cells. The possible damages may occur obeying a tissue-specific profile, and the effect on human apical papilla cells (hAPC) remains unknown. Therefore, this study aimed to evaluate DMSO effects on the viability and mineralization activity in hAPC cultures in vitro and to establish standards of maximum concentrations for its use in laboratory routines.

Raman Spectroscopic Analysis of Urinary Creatine and Phosphate in Athletes: Pre- and Post-Training Assessment.

The aim of this study was to detect biochemical components in the urine of bodybuilders who ingested creatine pretraining compared to individuals who did not ingest creatine after physical exercise using Raman spectroscopy.
