Antifungal Susceptibility Testing of Aspergillus spp. by Using a Composite Correlation Index (CCI)-Based Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry Method Appears To Not Offer Benefit over Traditional Broth Microdilution Testing.

spp. cause serious invasive lung infections, and is the most commonly encountered clinically significant species. Voriconazole is considered to be the drug of choice for treating infections; however, rising resistance rates have been reported.

Isoform specific changes in PPAR alpha and beta in colon and breast cancer with differentiation.

To investigate the role of peroxisome proliferator-activated receptors (PPARs) alpha and beta in the differentiation of colon cancer cells, we differentiated HT-29 cells using sodium butyrate (NaB) and culturing post-confluence and assessed differentiation using the marker intestinal alkaline phosphatase. While PPARalpha levels only changed with culturing post confluence, PPARbeta levels increased independent of the method of differentiation. To explore further the differences induced by NaB, we assessed changes in both PPAR isoforms in MCF-7 breast cancer cells cultured in the presence of NaB over 48h.
