Hepatocellular carcinoma (HCC) shares only a small proportion of hyperechoic liver tumors detected in MHTS and mimics hemangioma on ultrasonography (US). The precise diagnosis of HCC is hence difficult in MHTS, but presence or absence of underlying chronic liver disease and serum alfa-fetoprotein (AFP) titer might provide useful informations.
Poly(ADP-ribose) polymerase (PARP) is a nuclear enzyme that recognizes and binds to the nicks and ends of DNA, and catalyses successive ADP-ribosylation reactions. To clarify the function of PARP at the molecular level, we searched proteins which interact with PARP. In the auto-modification domain of PARP in Drosophila, there is a putative leucine-zipper(More)
Periodontitis is regarded to have a close relationship to diabetes mellitus. In Japan, some cohort studies have indicated that there is a significant positive association of obesity plus metabolic syndrome with periodontal diseases. As such, an increasing number of studies suggest a relationship between periodontitis and diabetes, most of which are(More)
Aggressive periodontitis (AgP), a severe and early onset type of periodontitis, is thought to be subject to significant genetic background effects. Formyl peptide receptor 1 (FPR1) is a gene strongly implicated in AgP. To determine whether variations in this gene are associated with AgP, we performed an association study with 49 AgP patients and 373(More)
To better understand genome structure and the expression of α/β-gliadin multigenes in hexaploid wheat, bacterial artificial chromosome (BAC) clones containing α/β-gliadin genes from the three loci, Gli-A2, Gli-B2, and Gli-D2, were screened. Based on their restriction fragment patterns, we selected five BAC clones, namely, two clones for Gli-A2, two clones(More)
OBJECTIVES Chronic inflammation of periodontitis aggravates glycemic control in type 2 diabetic patients through aggravation of insulin resistance. Increased or decreased release of various inflammatory mediators, such as high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6 and adipokines, such as adiponectin,(More)
Aims/Introduction: Diabetes mellitus and periodontitis are closely related. A huge number of reports has addressed the effect of periodontal intervention therapy on glycemic control, but no reports have addressed the effect of glycemic intervention therapy on periodontal disease in type 2 diabetic patients. The aim of this study was to examine the effect of(More)
UNLABELLED Aims/Introduction:  Chronic inflammation aggravates glycemic control in patients with type 2 diabetes mellitus. An increase or decrease in the release and activities of various inflammatory mediators, such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and C-reactive protein (CRP), are presumed to be responsible for inducing insulin(More)
Periodontal disease is considered to be a risk factor for threatened preterm labor (TPL) and preterm birth (PB), but pathogenic mechanisms have not yet been elucidated. We hypothesized that infection with periodontopathic bacteria may enhance thrombosis through molecular mimicry with TLRVYK peptides on beta-2 glycoprotein I, a target molecule in(More)
Recently, the Er:YAG and CO2 lasers have been applied in periodontal therapy. However, the characteristics of laser-irradiated root cementum have not been fully analyzed. The aim of this study was to precisely analyze the alterations of root cementum treated with the Er:YAG and the CO2 lasers, using non-decalcified thin histological sections. Eleven(More)
