Benzothienobenzothiophene (BTBT) and derivatives have received increasing attention as organic field-effect transistor materials and molecular conductors. This report presents the first synthesis of metal complexes involving a BTBT moiety, which was achieved by complexation of 2,2'-bipyridyl complexes of Pt(ii) and Pd(ii) with dihydroxy-substituted BTBT (1) as a new π-extended catecholato ligand (tBu2Bpy = 4,4'-di-tert-butyl-2,2'-dipyridyl). The resulting complexes M(tBu2Bpy)(O2BTBT) (M = Pt (3Pt) and Pd ( ...

The objective of this study was to develop a novel polymerase chain reaction (PCR) method to comprehensively analyze salivary bacterial flora.The bacterial flora in the saliva of 10 healthy persons and 11 patients with odontogenic infections were examined using a DNA extraction method with a high level of cell destruction efficiency and a novel universal primer set to amplify approximately 580 bp of the 16S rDNA sequence.Streptococcus (54.5%), Neisseria (14.7%), Actinomyces (8.4%), Gemella (4.1%), Granulicatella ( ...

The effects of aging on the multi‐organ Carcinogenesis induced in rats by N‐methyl‐N‐nitrosourea (MNU), a direct carcinogen which does not need metabolic activation to exert carcinogenicity, were examined in male F344 rats. In the first experiment, rats at 6, 52, and 98 weeks of age were treated with MNU (20 mg/kg body weight, i.p.) twice weekly for 6 weeks and then maintained without any further treatment for 24 weeks in the case of young and middle‐aged rats and for 18 weeks in the case of the old ...

Expression of the DCC (deleted in colorectal cancer) protein is strongly induced during the neural differentiation of mouse P19 embryonal carcinoma (EC) cells that occurs when these cells are treated with retinoic acid (RA). Myc-associated zinc finger protein (MAZ) is a DNA-binding protein that is widely expressed and functions in human, mouse and hamster cells as an activator, an initiator or a terminator of transcription. However, the biological functions of MAZ remain elusive. We report here that ...

Major depressive disorder (MDD) is associated with repeated exposure to environmental stress. Autophagy is activated under various stress conditions that are associated with several diseases in the brain. This study was aimed at elucidating the autophagy signaling changes in the prefrontal cortex (PFC) under repeated social defeat (RSD) to investigate the involvement of microglial autophagy in RSD-induced behavioral changes. We found that RSD stress, an animal model of MDD, significantly induced initial ...

We study theoretically competition between the charge ordering and the superconductivity in two-dimensional organic conductor beta-(meso-DMBEDT-TTF)_2PF_6. We analyze the extended Hubbard model on a weakly-dimerized lattice based on the random phase approximation and Eliashberg equations. We found reentrant behavior of the checkerbord-type charge-ordered phase in the phase diagram, and the triplet superconductivity due to the charge fluctuation in the neighboring region. In the low temperature and ...

Intracystic fluid was aseptically collected from 11 patients with postoperative maxillary cyst (POMC), and DNA was extracted from the POMC fluid. Bacterial species were identified by sequencing after cloning of approximately 580 bp of the 16S rRNA gene. Identification of pathogenic bacteria was also performed by culture methods. The phylogenetic identity was determined by sequencing 517-596 bp in each of the 1139 16S rRNA gene clones. A total of 1114 clones were classified while the remaining 25 ...

Compatibility between risperidone and soft drinks was examined by means of isothermal titration microcalorimetry, and the interaction of risperidone with tea tannin- (-)-epigallocatechin, (-)-epicatechin, theaflavin and their gallates-was investigated thermodynamically. Risperidone exothermically bound to tea tannin monomers with a binding affinity of 103-104 M-1 in aqueous solution to form an insoluble complex at a 1:1 molar ratio. The binding reaction was characterized by small enthalpy and entropy changes, ...

To investigate whether MAZ (Myc-associated zinc finger protein) affects the expression of the c-myc gene during the retinoic acid-induced (RA-induced) neuroectodermal differentiation of P19 embryonal carcinoma (EC) cells, we introduced a CAT reporter construct, human c-myc promoter/CAT (pMyc2CAT), and a mutant CAT derivative that lacked an ME1a1 site (pMyc1CAT) into P19EC cells to monitor the promoter activity of the c-myc gene. The expression of CAT in pMyc2CAT-transformed cells declined fivefold after ...

Abstract: Gene therapy based on gene‐specific nucleic acids has moved from theory to a practical possibility in a very short time. The new DNA and RNA therapeutic reagents are intended to stop the growth of cancerous cells or the production of viruses. At the practical level, the efficacy of antisense oligomers as therapeutic reagents has been carefully examined in various clinical contexts. For the efficient use of antisense nucleic acids as pharmaceutical agents, a complete analysis of their mechanisms ...

In repetitive measurements of flow-mediated dilatation (FMD), the duration of the interval between measurements remains controversial. In this pilot study, we conducted three sequential measurements of low–flow-mediated constriction (L-FMC), FMD and flow-mediated total dilation (FMTD; L-FMC+ FMD) at baseline and intervals of 15 and 60 min in 30 healthy males. FMD15, L-FMC15, and FMTD15 were significantly lower than the respective first measurements, but all indices showed full recovery at 60 min in ...

Complex formation between piperazine derivatives (PD) and green tea polyphenols (GTP) in an aqueous solutions and the mechanism were studied by isothermal titration microcalorimetry and molecular modeling study. Lomerizine dihydrochloride (LMZ), cetirizine dihydrochloride (CTZ) and hydroxyzine dihydrochloride (HXZ) were used as PD, and (−)-epigallocatechin gallate (EGCg) and (−)-epigallocatechin (EGC) were used as GTP. The mixed solutions of PD (except HXZ) and EGCg were cloudy because an insoluble complex was ...

Abstract Strongly enhanced quantum fluctuations often lead to a rich variety of quantum-disordered states. Developing approaches to enhance quantum fluctuations may open paths to realize even more fascinating quantum states. Here, we demonstrate that a coupling of localized spins with the zero-point motion of hydrogen atoms, that is, proton fluctuations in a hydrogen-bonded organic Mott insulator provides a different class of quantum spin liquids (QSLs). We find that divergent dielectric behavior ...

We study superconductivity mediated by the charge fluctuation in two-dimensional organic conductor β-(meso-DMBEDT-TTF)2PF6. We consider the extended Hubbard model on a weakly dimerized lattice, and solve the Eliashberg equations based on the random phase approximation. We found reentrant behavior of the checkerboard-type charge-ordered phase in the phase diagram, and the triplet superconductivity due to the charge fluctuation in the neighboring region. This results well agree with the experimental ...

An 80-year-old man was admitted to our hospital with a diagnosis of primary hepatic actinomycosis determined based on a percutaneous aspiration biopsy. The abscesses and state of liquefaction were easily and effectively visualized on contrast-enhanced ultrasonography. Ampicillin/sulbactam was administered; however, lesions of hepatic actinomycosis suddenly infiltrated the diaphragm and right thorax six months later. A drainage tube was inserted into the right thoracic space, and the pleural effusion ...

Evidence of a direct comparison between dipeptidyl-peptidase 4 inhibitors (DPP-4is) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) remains lacking, and no clear treatment strategy or rationale has been established using these drugs. This study aimed to compare the overall efficacy and safety of DPP-4is and the SGLT2i luseogliflozin in patients with type 2 diabetes mellitus (T2DM).Patients with T2DM who had not used antidiabetic agents or who had used antidiabetic agents other than SGLT2is ...
