OBJECTIVE To observe the effect of exercise preconditioning (EP) on pressure overload-induced pathological cardiac hypertrophy and explore related mechanisms. METHODS Ten-week-old male Sprague-Dawley rats (n = 80) were randomly divided into four groups via random number table method: sham, TAC, EP + sham and EP + TAC. Two EP groups were subjected to 4 weeks of treadmill training, and followed...

The imbalance between reactive oxygen species (ROS) production and total antioxidant capacity (TAC) in seminal fluid indicates oxidative stress and is correlated with male infertility. A composite ROS-TAC score may be more strongly correlated with infertility than ROS or TAC alone. We measured ROS, TAC, and ROS-TAC scores in semen from 127 patients and 24 healthy controls. Of the patients, 56 h...

INTRODUCTION We assessed our clinical experience with de novo kidney transplant recipients from living donors who received once-daily tacrolimus (OD TAC). In addition, we investigated tacrolimus pharmacokinetics and compared the dose of tacrolimus in de novo kidney transplant patients treated with OD TAC or twice-daily tacrolimus (BD TAC). MATERIAL AND METHODS Ten patients (3 ABO incompatible...

BACKGROUND Tacrolimus is available as twice-daily Prograf® (Tac-BID) and the once-daily formulation, Advagraf® (Tac-OD). Although therapeutically equivalent, some transplant recipients require dose adjustments to achieve similar tacrolimus trough concentrations [Tac C0] after conversion between formulations. Tacrolimus is primarily metabolized by cytochrome P450 3A5 (CYP3A5). We sought to deter...

I-TAC, IP10, and Mig are interferon-gamma inducible CXC chemokines that share the same G-protein-coupled receptor CXCR3, which is preferentially expressed on Th1 lymphocytes. We have explored the structure-function relationship of the CXCR3 ligands, in particular of I-TAC, which has highest affinity for CXCR3 and is the most potent agonist. A potent antagonist for CXCR3 was obtained by NH(2)-te...

Background. In this retrospective study, we compared the efficacy of tacrolimus (TAC) or prednisolone (PSL) for maintenance therapy in patients with ulcerative colitis (UC) at remission. Methods. The study patients were followed up for at least one year after induction of remission with either PSL (n = 55, between April 2004 and March 2014) or TAC (n = 40, between April 2009 and March 2014). Th...

We investigated pregnancy outcome following transabdominal cerclage (TAC) in women with cervical insufficiency (CI) and explored parameters for predicting pregnancy outcomes following TAC. In this retrospective cohort study, we included 161 women with TAC. We considered demographic, obstetric, and gynecologic histories, pre- and postoperative cervical length (CL), and CL at 20-24 weeks as param...

  TAC, MMF and MP are used in pediatric kidney tx. The cytochrome P450 (CYP)3A5 enzyme appears to play a role in TAC metabolism. The aims of this study were to investigate CYP3A5 polymorphism's effect on TAC dosing and the age dependency of TAC dosing by testing blood concentrations, and the interaction between steroids and TAC during the first year after tx. Genomic DNA was extracted and ampli...

Hypertrophic stimuli cause transcription of the proto-oncogene c-Myc (Myc). Prior work showed that myocardial knockout of c-Myc (Myc) attenuated hypertrophy and decreased expression of metabolic genes after aortic constriction. Accordingly, we assessed the interplay between Myc, substrate oxidation and cardiac function during early pressure overload hypertrophy. Mice with cardiac specific, indu...

BACKGROUND/AIMS To investigate the drug survival rate of tacrolimus (TAC) and analyze the potential predictors of this rate in patients with rheumatoid arthritis (RA) in routine care. METHODS2018-01-16 In this retrospective longitudinal study, we enrolled 102 RA patients treated with TAC from April 2009 to January 2014 at a tertiary center in South Korea. The causes of TAC discontinuation wer...
