doi: 10.2147/IJN.S434626

Figure Lengend Snippet: Viability of healthy human cells (HFF-1) exposed to nanoliposome-encapsulated tarin (upper panels) and free tarin (bottom panels) for 24 h and 48 h. The viability of HFF-1 cells in cultures was determined employing resazurin as an indicator. The x-axis in the upper panel refers to the encapsulated tarin concentration, while empty liposomes refer to the corresponding volume of liposomal solution used to reach that concentration. *p< 0.05 compared to the control. ns – non-significant relative to the control.

doi: 10.1101/2023.11.01.565095

Figure Lengend Snippet: Effect of known anti-toxoplasma agents (A) and pyrimidine analogues (B) on intracellular tachyzoites and on uninfected HFF cells (C). Data were plotted to a log[Inhibitor] vs response sigmoid model with variable slope (A, B) or an equation for two-site competition (C) in Prims 9 to determine EC 50 values. The curves are single experiments, representative of at least 2 (pyrimethamine) or 3 (all other compounds) independent, identically-performed experiments.

Figure Lengend Snippet: Impact of DNX on the wound healing response in UVA-exposed HFF-1 cells. ( A ) DNX counteracts the impediments in wound healing caused by UVA exposure. Upon reaching confluency, cells were scratched using a pipette tip and subsequently pretreated with DNX and VitC before UVA exposure. Inverted images (40× magnifications, 400 µm scale bar) of the scratched HFF-1 cells were captured at the 0 and 24 h marks post irradiation. ( B ) The wound healing assay’s graph, representing % wound closure, was generated by analyzing the captured inverted images through the Image-Pro Plus 6.0 Software. Data are expressed as the mean ± standard deviation of three independent experiments. Ns: non-significance, * p < 0.05.
