Highly sensitive quantification of key regulatory oxysterols in biological samples by LC-ESI-MS/MSs⃞

Journal of Lipid Research, 2009
We describe a highly sensitive and specific method for the quantification of key regulatory oxysterols in biological samples. This method is based upon a stable isotope dilution technique by liquid chromatography-tandem mass spectrometry (LC-MS/MS ...

Prediction of pyrotinib exposure based on physiologically-based pharmacokinetic model and endogenous biomarker

Frontiers in Pharmacology, 2022
Pyrotinib, a novel irreversible epidermal growth factor receptor dual tyrosine kinase inhibitor, is mainly (about 90%) eliminated through cytochrome P450 (CYP) 3A mediated metabolism in vivo.

Effect of CYP3A4 metabolism on sex differences in the pharmacokinetics and pharmacodynamics of zolpidem

Scientific Reports, 2021
To investigate pharmacokinetic and pharmacodynamic differences of zolpidem between males and females and their causes, including CYP3A4 activity. A single oral dose of zolpidem (10 mg) was administered to 15 male and 15 female healthy subjects.

25-Hydroxycholesterol Effect on Membrane Structure and Mechanical Properties [PDF]

, 2021
Cholesterol is responsible for the plasticity of plasma membranes and is involved in physiological and pathophysiological responses. Cholesterol homeostasis is regulated by oxysterols, such as 25-hydroxycholesterol.

NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Clinical relevance of pharmacogenomic information for improving prescribing practices in acutely admitted older medical patients

British Journal of Clinical Pharmacology, EarlyView.
Aims Safe prescribing and effective medication review during acute hospitalization depends on accurate information about liver and kidney function because these organs are responsible for the elimination of most medications. While estimates for kidney function are widely used, comparable markers of hepatic drug‐metabolizing capacity are not routinely ...

A panel of altered blood oxysterols in patients with mild cognitive impairment: A novel combined diagnostic marker

Pharmacological Research
Perturbed cholesterol metabolism may play an important role in the development of dementia and its preclinical stage, mild cognitive impairment (MCI). Oxysterols, the metabolites generated during cholesterol oxidation, also appear to be risk factors for ...
