Automated Unsupervised Segmentation of Liver Lesions in CT scans via Cahn-Hilliard Phase Separation [PDF]

arXiv, 2017
The segmentation of liver lesions is crucial for detection, diagnosis and monitoring progression of liver cancer. However, design of accurate automated methods remains challenging due to high noise in CT scans, low contrast between liver and lesions, as well as large lesion variability.

In Vitro and Clinical Evaluations of UGT1A1‐, P‐gp‐, OATP1B1‐, and BCRP‐Mediated Drug–Drug Interactions of Belumosudil, a Potent ROCK2 Inhibitor

The Journal of Clinical Pharmacology, EarlyView.
Abstract Belumosudil is an oral selective rho‐associated coiled‐coil containing protein kinase 2 inhibitor, approved as a treatment for chronic graft‐versus‐host disease. Prior clinical studies demonstrated that coadministration with strong CYP3A4 inducers or proton pump inhibitors requires dose modification of belumosudil.

Prediction of Hepatic Clearance of Stereoselective Metabolism of Carvedilol in Liver Microsomes and Hepatocytes of Sprague-Dawley and Cytochrome P450 2D-Deficient Dark Agouti Rats

Journal of Pharmacy & Pharmaceutical Sciences, 2019
Hepatic clearance (CLh) of carvedilol (CAR), which is eliminated via stereoselective metabolism by the CYP2D subfamily of cytochromes P450 (CYPs), was predicted using liver microsomes and hepatocytes from Sprague-Dawley (SD) rats and CYP2D-deficient Dark

Physiologically Based Pharmacokinetic (PBPK) Model to Predict the Magnitude of Drug–Drug Interaction Between Fezolinetant and CYP1A2 Inhibitors

The Journal of Clinical Pharmacology, EarlyView.
Abstract Fezolinetant is a non‐hormonal, selective neurokinin 3 receptor antagonist approved in multiple countries including the United States, in Europe, and in Asia for the treatment of moderate to severe vasomotor symptoms in menopausal women. Fezolinetant is primarily metabolized by CYP1A2 and was found to be a sensitive substrate for CYP1A2 ...

Inhibition of rat microsomal lipid peroxidation by the oral administration of D002

Brazilian Journal of Medical and Biological Research, 2000
The effect of D002, a defined mixture of higher primary alcohols purified from bee wax, on in vivo and in vitro lipid peroxidation was studied. The extent of lipid peroxidation was measured on the basis of the levels of thiobarbituric acid reactive ...

Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

Exclusive localization in peroxisomes of dihydroxyacetone phosphate acyltransferase and alkyl-dihydroxyacetone phosphate synthase in rat liver.

Journal of Lipid Research, 1993
Dihydroxyacetone phosphate acyl transferase (DHAP-AT), alkyl dihydroxyacetone phosphate synthase (alkyl-DHAP-synthase), and glycerol-3-phosphate acyltransferase (GPAT) activities were investigated under optimal assay conditions using highly purified ...
