Decreased expression of hyaluronan synthase and loss of hyaluronan-rich cells in the anterior tibial fascia of the rat model of chemotherapy-induced peripheral neuropathy.

Introduction: Previous studies on chemotherapy-induced peripheral neuropathy (CIPN) have focused on neuronal damage. Although some studies have revealed that the fascia is an important sensory organ, currently, we do not know about chemotherapy drug-induced fascial dysfunction.

Objectives: This study aimed to explore the fascia as a nonneural cause of mechanical hypersensitivity in CIPN by investigating the expression of hyaluronic acid synthase (HAS) and histology of the fascia in an animal model of CIPN.

Intrathecal Administration of the α1 Adrenergic Antagonist Phentolamine Upregulates Spinal GLT-1 and Improves Mirror Image Pain in SNI Model Rats.

Mirror image pain (MIP) is a type of extraterritorial pain that results in contralateral pain or allodynia. Glutamate transporter-1 (GLT-1) is expressed in astrocytes and plays a role in maintaining low glutamate levels in the synaptic cleft. Previous studies have shown that GLT-1 dysfunction induces neuropathic pain.

Portal Venous Gas Following Ingestion of Hydrogen Peroxide Successfully Treated with Hyperbaric Oxygen Therapy.

The primary toxicity of hydrogen peroxide results from its interaction with catalase, which liberates water and oxygen. We report the case of a 14-year-old Japanese girl with portal venous gas that was caused by oxygen liberated from intentionally ingested hydrogen peroxide. Although she had a past history of atrial septal defect, recovery without cardiac or neurological sequelae was achieved using hyperbaric oxygen therapy.

Successful Post-Transplant Psychiatric Interventions During Long-Term Follow-Up of Patients Receiving Liver Transplants for Alcoholic Liver Disease.

BACKGROUND Around 20-30% of patients who undergo liver transplantation (LT) for alcoholic liver disease (ALD) will resume heavy drinking after LT. It is crucial to control post-transplant relapse of alcohol use, because alcoholic recidivism has been shown to have a negative impact on post-transplant compliance and long-term outcomes of LT recipients. However, there is currently no specific, effective psychiatric intervention for preventing additional alcohol consumption in clinical practice.

Risk of alcohol use relapse after liver transplantation for alcoholic liver disease.

Aim: To investigate factors, including psychosocial factors, associated with alcoholic use relapse after liver transplantation (LT) for alcoholic liver disease (ALD).

Methods: The clinical records of 102 patients with ALD who were referred to Nagoya University Hospital for LT between May 2003 and March 2015 were retrospectively evaluated. History of alcohol intake was obtained from their clinical records and scored according to the High-Risk Alcoholism Relapse scale, which includes duration of heavy drinking, types and amount of alcohol usually consumed, and previous inpatient treatment history for alcoholism.

In vitro quantitative determination of the concentration of the polymerization agent methyl 2-benzoylbenzoate in intravenous injection solution and the cytotoxic effects of the chemical on normal human peripheral blood mononuclear cells.

In previous studies, we detected the photoinitiators 1-hydroxycyclohexyl phenyl ketone (1-HCHPK) and 2-methyl-4'-(methylthio)-2-morpholinopropiophenone (MTMP) in an intravenous injection solution. Importantly, 1-HCHPK and MTMP have been demonstrated to be cytotoxic to normal human peripheral blood (PB) mononuclear cells (MNC). Cell death (apoptosis) pathways can be classified into two modes, caspase-dependent and -independent pathways.

Postoperative Psychiatric Complications in Living Liver Donors.

Background: To understand the impact of psychologic variables on donor quality of life, we studied long-term data on postoperative psychiatric complications in living liver donors. This study is a focused psychological investigation of diagnoses, treatments, and long-term clinical courses of living liver donors with psychiatric complications.

Methods: Of the 142 donors who underwent live-donor liver transplantation at Nagoya University Hospital between April 2004 and July 2014, we investigated those without a history of mental illness who had developed such illness after transplantation and required psychiatric treatment.

Photoinitiators enhanced 1,2-dichloropropane-induced cytotoxicity in human normal embryonic lung fibroblasts cells in vitro.

Dichloromethane (DCM) and 1,2-dichloropsropane (DCP) have various uses, including being solvents for paint removers. Photoinitiators are also used in a wide range of commercial applications such as printing. These chemicals have been shown to induce cytotoxic effects.

The polymerization agent, 2-methyl-4'-(methylthio)-2-morpholinopropiophenone induces caspases-3/7 in human blood mononuclear cells in vitro.

Our previous studies detected the presence of a photoinitiator 2-methyl-4'-(methylthio)-2-morpholinopropiophenone (MTMP) in an intravenous (i.v.) injection bag solution.

[Alcohol dependence and liver transplantation: transplant coordinator's view].

Patients with alcohol-related liver failure are highly probably complicated by alcohol dependence according to the definition in WHO-ICD. Not a few such patients are introduced to liver transplant program when they are decompensated and face the need for liver replacement. Transplant team should evaluate them thoroughly also from the viewpoint of dependence medicine and multidisciplinary approach including psychiatrist is indispensable for the decision of psychosocial indication.

[Psychosocial aspects of liver transplantation indication criteria for alcohol-related liver failure].

Objectives: Consensus regarding psychosocial aspects relevant for the liver transplantation indication criteria in case of alcohol-related liver failure remains to be established. Thus we investigated the psychosocial aspects of candidates for liver transplantation for alcohol-related liver failure in order to determine the indication criteria.

Subjects: We evaluated the psychosocial aspects of 19 candidates (14 male and 5 female patients) who met the physical liver transplantation indication criteria for alcohol-related liver failure at Nagoya University Hospital between 2004 and 2012.

Carbon-sulfur bond cleavage reactions of dibenzothiophene derivatives mediated by iron and ruthenium carbonyls.

A thermal reaction of 6-(4''-dibenzothienyl)-2,2'-bipyridine (bpyDBT) with [Ru(3)(CO)(12)] produced a sulfur-bridged triruthenium complex via double carbon-sulfur bond cleavage and CO insertion, while a diiron(I,I) complex containing a thiametallacycle was obtained by a photochemical reaction of bpyDBT with [Fe(CO)(5)].

Relationship between parents' report rate of twin language and factors related to linguistic development: older sibling, nonverbal play and preschool attendance.

The definition and nature of twin language has been a focus of recent studies concerned with the phenomenon. There has been a call for a tighter definition and understanding of the meaning of twin language (Thorpe et al., 2001).

L-Canavanine modulates cellular growth, chemosensitivity and P-glycoprotein substrate accumulation in cultured human tumor cell lines.

L-Canavanine (L-CAV) is a naturally occurring L-arginine analog that induces the formation of non-functional proteins in a variety of organisms. Previous studies have shown that L-CAV is cytotoxic for several human tumor cell lines. In this study, we have evaluated the cytotoxicity of L-CAV for both parental and multi-drug resistant (MDR) human tumor cells.

The potential of a novel polyamine transport inhibitor in cancer chemotherapy.

The polyamines, putrescine (PUT), spermidine (SPD) and spermine (SPM), are a family of low molecular weight organic cations that are essential for cell growth, differentiation and neoplastic transformation. The marked compensatory increase in extracellular polyamine influx may be a reason for the unsatisfactory clinical chemotherapeutic effect of polyamine synthesis blockers like difluoromethylornithine (DFMO). In this study, a polymeric conjugate of SPM (poly-SPM) that blocks the import of polyamines into mammalian cells was used to test the potential therapeutic exploitation of the polyamine transport system in anticancer therapy.

Reversal of doxorubicin, etoposide, vinblastine, and taxol resistance in multidrug resistant human sarcoma cells by a polymer of spermine.

We have previously described the synthesis of a cytotoxic polymeric conjugate of spermine (Poly-SPM) which is able to inhibit the transport of polyamines (spermine, spermidine, and putrescine) into normal and malignant cells. Recent studies examining the toxicity of Poly-SPM in parental and multidrug resistant (MDR) cancer cells have revealed a cross-resistance in the MDR variant Dx5 to the toxic effects of the conjugate in the MDR-positive cells. There were also differences in spermine and putrescine uptake rates between parental and MDR-positive with the MDR-positive cells having a lower Vmax and a higher Km.

Treatment of high-risk acute lymphoblastic leukemia in children using the AL851 and ALHR88 protocols: a report from the Kyushu-Yamaguchi Children's Cancer Study Group in Japan.

A total of 125 children, who were diagnosed as having high-risk acute lymphoblastic leukemia (ALL), were treated with two consecutive protocols designated as AL851 (1985-1988) and ALHR88 (1988-1990). All patients received induction therapy consisting of vincristine (VCR), prednisolone (PSL), daunorubicin (DNR), and I-asparaginase (I-Asp). In the ALHR88 protocol, the patients whose blasts in the bone marrow (BM) were > or = 25% on day 14 of induction therapy and who were classified into T-cell type received additional cytosine arabinoside (AraC).

17 beta-estradiol glucuronide: an inducer of cholestasis and a physiological substrate for the multidrug resistance transporter.

The multidrug resistance (MDR) gene family has been shown to be highly expressed in several normal tissues including the canalicular membrane of the hepatocyte. We report that a cholestatic estrogen metabolite, 17 beta-estradiol glucuronide (E217G), is a substrate for the MDR transporter, P-glycoprotein. In cytotoxicity studies, the MDR sarcoma cell line Dx5 was 4.
