The importance of TNF-α signals mediated by tumor necrosis factor receptor type 1 (TNFR1) in inflammation and fibrosis induced by carbon tetrachloride (CCl(4)), and in post-injury liver regeneration including a GFP/CCl(4) model developed as a liver repair model by bone marrow cell (BMC) infusion, was investigated. In mice in which TNFR1 was suppressed by(More)
Companion animal spontaneous tumors are suitable models for human cancer, primarily because both animal population and the tumors are genetically heterogeneous. Feline mammary carcinoma (FMC) is a highly aggressive, mainly hormone receptor-negative cancer, which has been proposed as a model for poor prognosis human breast cancer. We have identified and(More)
Bile acids in the rat bile were fractionated into unconjugated, glycine- and taurine-conjugated fractions by employing piperidino-hydroxypropyl Sephadex LH-20 ion-exchange chromatography. Subsequently, these fractions were analyzed by gas-liquid chromatography (GLC) and GLC-mass spectrometry using a Silicone AN-600 column. Not only lithocholic acid,(More)
In this paper, the turbo coded on-off keying with unequal transmission power allocation (UTPA) in optical wireless communications is evaluated. The turbo coded with UTPA allocates the different power on the message bit and parity bits at the turbo encoder outputs with total transmission power fixed. In the additive white Gaussian noise (AWGN) channel, the(More)
Delayed wound healing is a serious clinical problem in patients after surgery. A recent study has demonstrated that bone marrow-derived c-kit-positive (c-kit(+)) cells play important roles in repairing and regenerating various tissues and organs. To examine the hypothesis that surgical injury induces the mobilization and recruitment of c-kit+ cells to(More)
The purpose of this study was to confirm the therapeutic effects of mixed sheets consisting of peripheral blood mononuclear cells (PBMNCs) and fibroblasts on cutaneous skin ulcers. Vascular endothelial growth factor (VEGF) secretion in mixed cell sheets was much higher than in PBMNCs and fibroblasts. Concerning the mechanism, transforming growth factor beta(More)
Background. We present here 2 cases of acute twin-twin transfusion occurred during vaginal labor in monochorionic-diamniotic twin pregnancies. Case. Fetal heart rate tracings showed tachycardia in the donor twin in the first case, while they showed reassuring patterns in both twins in the second case. Conclusion. These differences in changes of fetal heart(More)
Partial nucleotide sequences of eight kinds of bird (common crane, gray pelican, goose, black swan, bewisk's swan, whooper swan, ostrich, and chicken) gene encoding quaking protein were analyzed. Variously sized bands were observed in all eight birds compared with the same sized band in mammals based on nested PCR results, and all sequence data showed a(More)
The effects of local anesthetics (tetracaine, procaine and lidocaine) on self-sustained electrical oscillations were studied for a lipid membrane comprising dioleyl phosphate (DOPH). This model membrane exhibits oscillation of the membrane potential in a manner similar to that of nerve membranes, i.e., repetitive firing, in the presence of an(More)
The local anesthetics, tetracaine, procaine and lidocaine, interacted with a negatively charged lipid membrane composed of dioleyl phosphate (DOPH), which exhibited a self-sustained oscillation of the membrane potential. The anesthetics depolarized the membrane potential when present in increasing concentrations, whereas they increased the membrane(More)
