The mechanism by which drugs inhibit organic anion transporter 1 (OAT1) was examined. OAT1 stably expressed in Chinese hamster ovary (CHO) cells, and <i>para</i>-aminohippurate (PAH) 6-carboxyfluorescein were the substrates. Most compounds (10 of 14) inhibited competitively, increasing Michaelis constant (<i>K</i><sub>m</sub>) without affecting maximal transport rate (<i>J</i><sub>max</sub>). Others mixed-type (lowering <i>J</i><sub>max</sub> <i>K</i><sub>m</sub>) or noncompetitive only)...

Background The submental island flap (SIF) is a reliable option for reconstructing defects in the facial region and offers several advantages when compared to free-flap alternatives. While reconstructive applications of SIF have been demonstrated lower face, there are limited reports on its utility as composite upper skeleton. To our knowledge, we report first cases (osteocutaneous) SIFs used reconstruction complex involving zygoma lateral orbit respectively. Case presentations Three...
