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

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. Blood samples were collected up to 12 h post-dose to determine plasma zolpidem concentrations.

Neuroimaging in Randomized, Multi-Center Clinical Trials of Endovascular Treatment for Acute Ischemic Stroke: A Systematic Review.

Appropriate use and analysis of neuroimaging techniques is an inevitable aspect of clinical trials for patients with acute ischemic stroke. Neuroimaging examinations were recently used to define the core eligibility criteria and outcomes in acute ischemic stroke research. Recent clinical trials for endovascular treatment in acute ischemic stroke have also demonstrated the efficacy or safety of endovascular treatment using various imaging modalities as well as clinical indices.

MRI for prediction of hemorrhagic transformation in acute ischemic stroke: a systematic review and meta-analysis.

Background: Hemorrhagic transformation increases mortality and morbidity in patients with acute ischemic stroke.

Purpose: The purpose of this study is to evaluate the diagnostic performance of magnetic resonance imaging (MRI) for prediction of hemorrhagic transformation in acute ischemic stroke.

Material And Methods: A systematic literature search of MEDLINE and EMBASE was performed up to 27 July 2018, including the search terms "acute ischemic stroke," "hemorrhagic transformation," and "MRI.

ZNF133 is associated with infliximab responsiveness in patients with inflammatory bowel diseases.

Background And Aim: Infliximab has been widely prescribed for treating inflammatory bowel disease (IBD). However, the response rates to infliximab differ among patients. Therefore, we aimed to identify the genetic and clinical markers that predict infliximab response.

Perfusion CT for prediction of hemorrhagic transformation in acute ischemic stroke: a systematic review and meta-analysis.

Objective: To investigate the diagnostic performance of perfusion CT for prediction of hemorrhagic transformation in acute ischemic stroke.

Methods: A computerized literature search of Ovid MEDLINE and EMBASE was conducted up to October 29, 2018. Search terms included acute ischemic stroke, hemorrhagic transformation, and perfusion CT.

Influence of Polymorphism on the Pharmacokinetic/Pharmacodynamic Characteristics of Carvedilol in Healthy Korean Volunteers.

Background: Carvedilol is commonly used to treat hypertension as a β- and α-adrenoreceptor blocker, but it is metabolized by and allele is dominant in Asian population. The objective of this study was to assess the influence of polymorphisms on the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of carvedilol in healthy Korean volunteers.

Methods: A PK/PD study for a single and multiple dosing of carvedilol were conducted.

Correlations between renal function and the total kidney volume measured on imaging for autosomal dominant polycystic kidney disease: A systematic review and meta-analysis.

Purpose: To provide a systematic summary of total kidney volume (TKV) as an imaging biomarker in clinical trials for autosomal dominant polycystic kidney disease (ADPKD), focusing on the correlation between TKV and renal function.

Methods: A computerized literature search was performed using MEDLINE and EMBASE databases for studies that evaluated the correlation between TKV and the glomerular filtration rate (GFR) and between the TKV growth rate and GFR decline rate. A meta-analysis was performed to generate the summary correlation coefficient (r).

Effects of CYP2C19 Genetic Polymorphisms on PK/PD Responses of Omeprazole in Korean Healthy Volunteers.

The aim of this study was to examine the effects of CYP2C19*2 and *3 genetic polymorphisms on omeprazole pharmacokinetic (PK) and pharmacodynamic (PD) responses. Twenty-four healthy Korean volunteers were enrolled and given 20 mg omeprazole orally once daily for 8 days. The genotypes of CYP2C19 single nucleotide polymorphisms (SNPs) (*2, *3, and *17) were screened.

The influences of SLCO1B1 and ABCB1 genotypes on the pharmacokinetics of simvastatin, in relation to CYP3A4 inhibition.

Aim: To investigate the combined effects of SLCO1B1 and ABCB1 genotypes on the pharmacokinetics of simvastatin and its active metabolite simvastatin acid, in relation to CYP3A4 inhibition.

Methods: We conducted a single-dose pharmacokinetic study of simvastatin in 26 healthy volunteers screened for their SLCO1B1 c.521T>C and ABCB1 c.

Hepatoprotective effect of pinoresinol on carbon tetrachloride-induced hepatic damage in mice.

Forsythiae Fructus is known to have diuretic, anti-bacterial, and anti-inflammatory activities. This study examined the hepatoprotective effects of pinoresinol, a lignan isolated from Forsythiae Fructus, against carbon tetrachloride (CCl(4))-induced liver injury. Mice were treated intraperitoneally with vehicle or pinoresinol (25, 50, 100, and 200 mg/kg) 30 min before and 2 h after CCl4 (20 microl/kg) injection.

Palmatine attenuates D-galactosamine/lipopolysaccharide-induced fulminant hepatic failure in mice.

Palmatine is an isoquinoline alkaloid from Coptis chinensis, an herbal medicine used to treat various inflammatory diseases such as gastritis, edema and dermatitis. The present study examined the cytoprotective properties of palmatine on d(+)-galactosamine (GalN)/lipopolysaccharide (LPS)-induced fulminant hepatic failure. Mice were intraperitoneally given GalN (700 mg/kg)/LPS (10 microg/kg).

Inhibition of aroclor 1254-induced depletion of stored calcium prevents the cell death in catecholaminergic cells.

The relationship between depleting effects of polychlorinated biphenyls (PCBs) on the intracellular calcium store and PCBs-induced cell death in dopaminergic cells has not been fully evaluated. Here, we evaluated the effects of inhibitors of the release of ER-stored calcium on the cytotoxicities induced by 10 microg/ml of Aroclor 1254 (A1254; polychlorinated biphenyl mixture) in a catecholaminergic cell-line, CATH.a cells.

Effect of Holotrichia diomphalia larvae on liver fibrosis and hepatotoxicity in rats.

Holotrichia diomphalia larvae, one of the most widely used Korean folk medicinal preparations, have long been used for the treatment of chronic liver cirrhosis. The present study was undertaken to clarify whether extract of Holotrichia diomphalia larvae could prevent acute liver damage and liver fibrosis in rats. A single administration of Holotrichia diomphalia protected rats from acute liver damage induced by carbon tetrachloride (200 micro l/kg, i.
