Infrared Image-Enhancement Algorithm for Weak Targets in Complex Backgrounds.

Infrared small-target enhancement in complex contexts is one of the key technologies for infrared search and tracking systems. The effect of enhancement directly determines the reliability of the monitoring equipment. To address the problem of the low signal-to-noise ratio of small infrared moving targets in complex backgrounds and the poor effect of traditional enhancement algorithms, an accurate enhancement method for small infrared moving targets based on two-channel information is proposed.

Pharmacokinetic Alteration of Paclitaxel by Ferulic Acid Derivative.

P-glycoprotein (P-gp) is known to be involved in multidrug resistance (MDR) and modulation of pharmacokinetic (PK) profiles of substrate drugs. Here, we studied the effects of synthesized ferulic acid (FA) derivatives on P-gp function in vitro and examined PK alteration of paclitaxel (PTX), a well-known P-gp substrate drug by the derivative. Compound , the FA derivative chosen as a significant P-gp inhibitor among eight FA candidates by in vitro results, increased PTX AUC as much as twofold versus the control by reducing PTX elimination in rats.
