Uremic toxins have been suggested to promote progression of chronic renal failure by damaging tubular cells. Previous in vitro studies have indicated that some uremic toxins induce oxidative stress and activate NF-kappaB to upregulate plasminogen activator inhibitor-1 in tubular cells. These mechanisms may promote tubulointerstitial fibrosis. The present… (More)
To define the region on the short arm of chromosome 1 that is thought to include one or more tumour-suppressor genes for gastric cancers, we carried out loss of heterozygosity (LOH) studies in 26 gastric adenocarcinomas, using three restriction fragment length polymorphism (RFLP) markers and nine microsatellite markers. All tumours were informative with at… (More)
Molecular chaperone DnaK of halophilic Tetragenococcus halophilus JCM5888 was characterized under salinity conditions both in vitro and in vivo. The dnaK gene was cloned into an expression vector and transformed into Escherichia coli. The DnaK protein obtained from the recombinant E. coli showed a significantly higher refolding activity of denatured lactate… (More)
OBJECTIVE Cerebrospinal fluid (CSF) shunting can improve symptoms of elderly patients' idiopathic normal pressure hydrocephalus (iNPH). However, adjunctive means for confirming the diagnosis remain unavailable. We have previously reported the specific increase of leucine-rich alpha-2-glycoprotein (LRG) in iNPH CSF, and the present study investigates its… (More)
Microsatellite instability (MSI) was examined at 36 loci, and found in 9 (43%) of the 21 prostatic cancers. A loss of heterozygosity had occurred in five cases (24%). MSI did not correlate with clinical stage, but might play a role in the development of a subset of prostate cancers.
The synthesis and electrochemical properties of the DHDA-TTP donor, a hybrid of 2,5-bis(1,3-dithiolan-2-ylidene)-1,3,4,6-tetrathiapentalene (BDH-TTP) and 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathiapentalene (BDA-TTP), has been investigated, and its ability to form metallic cation-radical salts is elucidated.
Heat-capacity changes (deltaC(p)0) were determined for the complexation of 1-alkanecarboxylates with protonated hexakis(6-amino-6-deoxy)-alpha-cyclodextrin (per-NH3(+)-alpha-CD) and heptakis(6-amino-6-deoxy)-beta-cyclodextrin (per-NH3(+)-beta-CD). DeltaC(p)0 decreased with an increase in the binding constant (K) and plateaued at K = 4000 M(-1). The… (More)
COMBINED use of X-rays and bleomycin was initially proposed by J0rgensen (1972). The demonstration of synergism attracted much attention from clinicians as well as basic researchers. The question arose whether the effect can be attributed to a tissue mechanism or to cellular potentia-tion. In the mean time, several investigations have been carried out to… (More)
We have designed and experimentally implemented a circuit of inductively coupled superconducting charge qubits, where a Josephson junction is used as an inductance, and the coupling between the qubits is controlled by an applied magnetic flux. Spectroscopic measurements on the circuit are in good agreement with theoretical calculations. We observed… (More)
We have cloned and characterized the dnaK operon of Tetragenococcus halophila JCM5888. Nucleotide sequence analysis of cloned fragments showed that the dnaK operon consists of four open reading frames with the organization hrcA-grpE-dnaK-dnaJ. Two regulatory CIRCE (Controlling Inverted Repeat of Chaperone Expression) elements were identified in the region… (More)
