To improve the previous DNA/DNA nearest-neighbor parameters, thermodynamic parameters (deltaH degrees, deltaS degrees and deltaG degrees) of 50 DNA/DNA duplexes were measured. Enthalpy change of a helix initiation factor is also considered though the parameters reported recently did not contain the factor. A helix initiation factor for DNA/DNA duplex(More)
Mutations in genes encoding the epsilon, delta, beta and alpha subunits of the end plate acetylcholine (ACh) receptor (AChR) are described and functionally characterized in three slow-channel congenital myasthenic syndrome patients. All three had prolonged end plate currents and AChR channel opening episodes and an end plate myopathy with loss of AChR from(More)
PURPOSE To assess the efficacy and safety of S-1, a novel oral fluoropyrimidine derivative, we conducted a multicenter late phase II study in patients with advanced gastric cancer. PATIENTS AND METHODS Fifty-one patients who had received no previous chemotherapy were enrolled. Fifty patients were eligible for efficacy and safety analyses. The overall(More)
UNLABELLED The aim of this SPECT study was to determine the initial abnormality and longitudinal changes in regional cerebral blood flow (rCBF) in early Alzheimer's disease (AD) using statistical parametric mapping (SPM). METHODS rCBF was noninvasively measured using (99m)Tc-ethyl cysteinate dimer SPECT in 32 patients complaining of mild cognitive(More)
It is believed that the polymorphism observed in calcium carbonate crystals, such as aragonite and calcite in mollusk shells, is controlled by organic matrix proteins secreted from the mantle epithelia. However, the fine structures of these proteins are still unknown, and to understand the molecular mechanisms of mineralization process, detailed structural(More)
The end-plate species of acetylcholinesterase (AChE) is an asymmetric enzyme consisting of a collagenic tail subunit composed of three collagenic strands (ColQ), each attached to a tetramer of the T isoform of the catalytic subunit (AChE(T)) via a proline-rich attachment domain. The principal function of the tail subunit is to anchor asymmetric AChE in the(More)
We evaluated the effects of bezafibrate, a peroxisome proliferator-activated receptor (PPAR) pan-agonist, and GW501516, a PPARdelta agonist, on mice fed a methionine- and choline-deficient (MCD) diet, a model of non-alcholic steatohepatitis (NASH), to investigate (a) the efficacy of bezafibrate against non-alcholic steatohepatitis and (b) the relation(More)
Thermodynamics of 66 RNA/DNA duplexes containing single mismatches were measured by UV melting methods. Stability enhancements for rG. dT mismatches were the largest of all mismatches examined here, while rU.dG mismatches were not as stable. The methyl group on C5 of thymine enhanced the stability by 0.12 approximately 0.53 kcal mol(-)(1) depending on the(More)
Salvelinus leucomaenis (white-spotted charr) and S. malma (Dolly Varden) are distributed throughout Hokkaido Island, Japan, but sites where they occur in sympatry are rare. In general, S. malma inhabit upstream reaches and S. leucomaenis extend downstream to the ocean. Factors influencing their distribution were analyzed at four spatial scales ranging from(More)
OBJECTIVE To evaluate the diagnostic efficacy of simultaneous measurements of high-sensitivity des-gamma-carboxy prothrombin (H-DCP) and Lens culinaris agglutinin A-reactive alpha-fetoprotein (AFP-L3) in small hepatocellular carcinoma (HCC). METHODS Sixty-one patients with small HCCs < or = 2 cm in diameter and 134 controls (chronic hepatitis: 59 cases;(More)
