Clinical pharmacological study of dotinurad administered to male and female elderly or young subjects.

Background: Dotinurad is a novel selective urate reabsorption inhibitor (SURI) that selectively inhibits the reabsorption of uric acid in renal tubules and promotes the excretion of uric acid into urine. In this study, the effects of age and gender on the pharmacokinetics (PK), pharmacodynamics (PD), and safety of dotinurad were evaluated in healthy subjects.

Methods: An open-label study of a single oral administration of dotinurad 1 mg was conducted in elderly (≥ 65 years) Japanese males and females, and young (20-35 years) males and females (six patients each).

Pharmacokinetic/pharmacodynamic modeling and simulation of dotinurad, a novel uricosuric agent, in healthy volunteers.

This study aimed to investigate the pharmacokinetic and pharmacodynamic (PK/PD) profiles of dotinurad, a novel uricosuric agent, and to construct a PK/PD model to predict serum urate (SUA) levels after dotinurad administration in healthy men. PK/PD model was constructed using single-dose study data considering the physiological features of urate handling. Model validation was performed by comparing the predicted SUA levels with the SUA levels in a multiple-dose study.

Plasma pentraxin 3 is associated with progression of radiographic joint damage, but not carotid atherosclerosis, in female rheumatoid arthritis patients: 3-year prospective study.

Pentraxin 3 (PTX3) has an important role in inflammation, immunity, and atherosclerosis. Rheumatoid arthritis (RA) is a chronic inflammatory disease featuring both joint damage and atherosclerosis. We investigated whether the plasma PTX3 level was associated with progression of joint destruction and subclinical atherosclerosis in RA patients.

Alcaftadine 0.25% versus Olopatadine 0.1% in Preventing Cedar Pollen Allergic Conjunctivitis in Japan: A Randomized Study.

: To compare alcaftadine and olopatadine ophthalmic solutions, and vehicle for preventing allergen-mediated conjunctivitis in Japanese subjects. : Japanese cedar pollen-sensitive subjects were randomized to alcaftadine 0.25%, olopatadine 0.

Phase I clinical trial of 99mTc-etarfolatide, an imaging agent for folate receptor in healthy Japanese adults.

Objective: Technetium etarfolatide ((99m)Tc-EF) is a radioactive diagnostic imaging agent that was developed to assess the expression of folate receptors in tumors. Administering folic acid prior to the administration of (99m)Tc-EF has been shown to improve SPECT images. Here, we conducted a phase I clinical trial to assess the safety, pharmacokinetics, and radiation dosimetry of (99m)Tc-EF injection following pre-administration of folic acid in healthy Japanese male adults.

Serum bile acid along with plasma incretins and serum high-molecular weight adiponectin levels are increased after bariatric surgery.

Bariatric surgery has been shown to improve glucose tolerance, although the mechanism has not been fully elucidated. Animal studies have suggested important roles of bile acid (BA) as a regulator of energy homeostasis and glucose metabolism. However, little is known about its role in humans.

Pioglitazone might prevent the progression of slowly progressive type 1 diabetes.

Although recent studies recommended that insulin should be administered to patients with slowly progressive type 1 diabetes, even those with non-insulin dependent status, patients prefer oral hypoglycemic agents to insulin injections. We report a slowly progressive type 1 diabetic patient whose insulin production was preserved for 4 years (SigmaC-peptide from 29.48 ng/mL to 24.

Combination of C-reactive protein and high molecular weight (HMW)-adiponectin reflects further metabolic abnormalities compared with each of them alone in Japanese type 2 diabetic subjects.

Objective: Serum C-reactive protein (CRP) and adiponectin levels predict atherosclerosis and coronary heart disease. However, the efficacy of the combination of both markers remains unknown. In the present study, we investigated whether the combination of CRP and adiponectin is associated with further metabolic abnormalities compared to each of them alone.

Significance of leptin and high-molecular weight adiponectin in the general population of Japanese male adolescents.

Adipokines play crucial roles in obesity-related insulin resistance in adults, but little is known in the general adolescent population. This study was designed to investigate the relationships between adipokines and metabolic parameters, the insulin resistance index, and proinflammatory cytokines in the general population of Japanese male adolescents. We studied 662 Japanese male high school students aged 16 to 17 years and 282 healthy Japanese male adults aged 30 to 61 years who received annual health checkups.

Kinetic and structural analysis of enzyme sliding on a substrate: multiple attack in beta-amylase.

Monte Carlo simulation of hyaluronidase reaction involving hydrolysis, transglycosylation and condensation.

The action of hyaluronidase on oligosaccharides from hyaluronan is complicated due to branched reaction paths containing hydrolysis, transglycosylation and condensation. The unit component of hyaluronan is a disaccharide, namely GlcA-(beta 1-->3)-GlcNAc where GlcA and GlcNAc are d-glucuronic acid and d-N-acetylglucosamine respectively. Hyaluronan is the linear polymer formed by these disaccharide units, linked together with beta 1-->4 glycosidic bonds.
