Anion recognition and anion sensing are of interest because anions play many important roles in living organisms. Most currently known anion sensors work only in organic solution, but sensors for biological applications are required to function in neutral aqueous solution. We have designed and synthesized a novel fluorescent sensor for anions. The sensor(More)
Late-onset hypogonadism (LOH) is a male-specific disorder caused by the age-related decline in androgens, such as testosterone (T). A sensitive liquid chromatography-electrospray ionization-tandem mass spectrometric (LC-ESI-MS/MS) method for the simultaneous quantification of T and its precursor, dehydroepiandrosterone (DHEA), in human saliva has been(More)
OBJECTIVE To examine the genetic polymorphism of CYP2C9 and CYP2C19 and its effect on the pharmacokinetics of phenytoin among 44 Japanese patients with epilepsy. METHODS Polymerase chain reaction tests with leukocyte deoxyribonucleic acid were used to detect the mutations for the amino acid substitution (Arg144-->Cys and Ile359-->Leu) in CgammaP2C9 and(More)
The pharmacokinetics of zonisamide was studied using routine therapeutic drug monitoring data from 68 epileptic patients. The 266 serum concentration data at steady-state after repetitive oral administration were analyzed using the nonlinear mixed effects model (NONMEM) program designed for estimation of population pharmacokinetic parameters. A(More)
We examined the effect of CYP2C9/19 polymorphisms on the pharmacokinetics of phenytoin in 17 Japanese patients with epilepsy. The maximal elimination rate (Vmax) of phenytoin was slightly decreased (up to 14%) in patients with CYP2C19 mutations for the defective allele. The Vmax values in patients with a CYP2C9 mutation for the heterozygous Ile/Leu359(More)
The population pharmacokinetic parameters of phenytoin were estimated using routine therapeutic drug monitoring data from 116 epileptic patients. The 531 serum concentration values at steady-state after repetitive oral administration were analyzed using a nonlinear mixed effects model (NONMEM) program designed for estimation of population pharmacokinetic(More)
We synthesised four tetrazolato-bridged dinuclear Pt(ii) complexes, [{cis-Pt(NH3)2}2(μ-OH)(μ-5-R-tetrazolato-N2,N3)](n+), where R is CH3 (1), C6H5 (2), CH2COOC2H5 (3), or CH2COO(-) (4) and n = 2 (1-3) or 1 (4). Their structures were characterised by (1)H, (13)C, and (195)Pt NMR spectroscopy, mass spectrometry, and elemental analysis, and the crystal(More)
Tc-HYNIC-annexin A5 can be considered as a benchmark in the field of apoptosis imaging. However, Tc-HYNICannexin A5 has characteristics of high uptake and long retention in non-target tissues such as kidney and liver. To minimize this problem, we developed a novel Tc-labeled annexin A5 using a bis(hydroxamamide) derivative [C3(BHam)2] as a bifunctional(More)
INTRODUCTION (68)Ga is a radionuclide of great interest as a positron emitter for positron emission tomography (PET). To develop a new bone-imaging agent with radiogallium, 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) was chosen as a chelating site and Ga-DOTA complex-conjugated bisphosphonate, which has a high affinity for bone, was(More)
