Specific inhibition of the transporter MRP4/ABCC4 affects multiple signaling pathways and thrombus formation in human platelets

Haematologica, 2022
The multidrug resistance protein 4 (MRP4) is highly expressed in platelets and several lines of evidence point to an impact on platelet function. MRP4 represents a transporter for cyclic nucleotides as well as for certain lipid mediators. The aim of the

Determination of Gastric Water Emptying in Fasted and Fed State Conditions Using a Compression-Coated Tablet and Salivary Caffeine Kinetics

Pharmaceutics, 2023
Because of the importance of gastric emptying for pharmacokinetics, numerous methods have been developed for its determination. One of the methods is the salivary tracer technique, which utilizes an ice capsule containing caffeine as a salivary tracer ...
