one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Organic anion transporting polypeptide (Oatp) 1a/1b knockout and OATP1B1 and -1B3 humanized mouse models are promising tools for studying the roles of these transporters in drug disposition. Detailed characterization of these models will help to better understand their utility for predicting clinical outcomes. To advance this approach, we carried out a comprehensive analysis of these mouse line...

The drug pump protein MRP2 is a membrane drug efflux transporter widely distributed in normal and tumor tissues. Its role is thought to be crucial for the disposition of many drugs and their substrates in different tissues. In this study, we aimed to examine the effects of systematic inflammation induced by lipopolysaccharide (LPS) on the expression and function of this transporter in rats. Jug...
Freshly isolated hepatocytes are considered the gold standard for in vitro studies of hepatic drug disposition. To ensure a reliable supply of cells, cryopreserved human hepatocytes are often used. ABC-superfamily drug efflux transporters are key elements in hepatic drug disposition. These transporters are often considered lost after isolation of hepatocytes. In the present study, the expressio...
P-Glycoprotein (P-gp) is an ATP-dependent drug efflux transporter involved in multidrug resistance and drug disposition in many organ systems. A majority of P-gp substrates are lipophilic amine drugs which also exhibit rapid extensive accumulation in lung tissue. P-gp is expressed in lung tissue, and the very nature of this drug efflux mechanism suggests a moderating role in pulmonary drug disp...
The author's previous theoretical study described the determination of a physiologically realistic structure of a mean residence time of an intravenously administered drug (Ďurišová 2012). This study continues previous work and the aim is to determine physiologically realistic structures of mean residence times of a drug administered either orally (MRTpo) or intramuscularly (MRTim). The determi...
OBJECTIVES Therapeutic hypothermia has been shown to decrease neurologic damage in patients experiencing out-of-hospital cardiac arrest. In addition to being treated with hypothermia, critically ill patients are treated with an extensive pharmacotherapeutic regimen. The effects of hypothermia on drug disposition increase the probability for unanticipated toxicity, which could limit its putative...
Integrated approach of in vivo and in vitro for evaluation of the involvement of hepatic uptake organic anion transporters in the drug disposition in rats using rifampicin as an inhibitor Abbreviations Cyp: cytochrome 450 Oatp: organic anion transporting polypeptide OAT: organic anion transporter DDI: drug-drug interactions NCE: new chemical entity SD: Sprague-Dawley LC/MS/MS: liquid chromatogr...
