Effects of Eltrombopag on the Cellular Ultrastructure of Cryptococcus

To study the effects of eltrombopag on the cellular structure of Cryptococcus, C. neoformans H99 or C. deuterogattii 8265 was cultured in RPMI 1640 medium containing 0.06 or 0 mg/L eltrombopag at 37° C. for 48 hours, and the cell morphology was examined by scanning electron microscopy (FEI Inspect S SEM, USA).

FIG. 3A and FIG. 3B are the images of C. neoformans H99 and C. deuterogattii R265 cells after incubation for 48 hours in the presence or absence of eltrombopag. According to FIGS. 3A-3B, both of the eltrombopag-treated Cryptococcus species produced a small number of incomplete buds on the cell surface. This phenomenon was not observed in cryptococcal cells without eltrombopag treatment. The results indicate that eltrombopag can inhibit the growth of Cryptococcus by affecting the development of normal cellular structures (such as the cell membrane or cell wall).

Selected samples were analyzed with a scanning electron microscope (SEM) with energy dispersive X-ray spectroscopy (EDX). Samples were fixed on carbon tape and coated with gold prior to analysis. A FEI Inspect S SEM was used for image capturing. Point analysis (elemental point composition) was performed on selected substrates (3-5 particles, 15-30 points) with an EDX detector (Oxford Instruments).

Tooth enamel was studied using scanning electron microscopy (SEM Inspect™ S, FEI, Hillsboro, OR, USA) after the shear bond test, bracket debonding, and polishing, the surface morphology of the. This electron microscope generates the image of a sample surface scanning with a focused electron beam. The electrons interact with the enamel atoms and thus produce various signals that provide information regarding the surface topography and chemical composition of the tooth. The specimens were removed from the artificial saliva they were stored in, patted dry with filter paper and analyzed in a low vacuum, 4.5 spot and 25.00 kV, 100× magnifications.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
