PURPOSE Third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have demonstrated potent activity against TKI resistance mediated by EGFR T790M. We studied whether noninvasive genotyping of cell-free plasma DNA (cfDNA) is a useful biomarker for prediction of outcome from a third-generation EGFR-TKI, osimertinib. METHODS(More)
The platelet P2Y(12) receptor is the target of clopidogrel therapy, which has been shown to reduce thromboembolic complications of atherosclerotic disease but has limitations in terms of variability of response and irreversibility of effect. This receptor is also a target for ticagrelor (AZD6140), the first reversibly binding oral P2Y(12) receptor(More)
This study investigated the effects of acute hyperglycemia on conscious rectal perception in response to two different rectal distension paradigms. Eleven healthy males were studied in random order on two separate days during euglycemia and hyperglycemia with blood glucose concentrations clamped to 3.8 +/- 0.6 and 14.8 +/- 0.86 mmol/liter, respectively.

A sensitive and rapid high performance liquid chromatographic method was developed for the determination of Cyclosporin A in plasma. Cyclosporin A was isolated from methanol-precipitated plasma using miniature compressed silica reverse-phase columns (Sep-Paks). In the method, 1 ml serum is precipitated in 3 ml methanol. After centrifugation 2 ml of(More)
