Abstract
Background Small, dense low-density lipoprotein (sd-LDL) increases in type 2 diabetes patients and causes arteriosclerosis. Non–high-density-lipoprotein cholesterol (non–HDL-C) is thought to be useful for predicting arteriosclerosis and sd-LDL elevation; however, there are no data about whether the triglyceride /low-density-lipoprotein cholesterol (TG/LDL-C) ratio is a valuable predictor for sd-LDL. Methods A total of 110 type 2 diabetes patients with hypertriglyceridemia were analyzed. No patients were treated with fibrates, but 47 patients were treated with statins. LDL-C was measured by the direct method. LDL-migration index (LDL-MI) using electrophoresis (polyacrylamide gel, PAG) was calculated, and a value ≥0.400 was determined to indicate an increase in sd-LDL. Simple regression analyses were carried out between LDL-MI and lipid markers. Receiver operating characteristic curves of lipid markers for predicting high LDL-MI were applied to determine the area under the curve (AUC), sensitivity, specificity, and cut-off point. Results LDL-MI correlated negatively with LDL-C (P = 0.0027) and PAG LDL fraction (P < 0.0001) and correlated positively with TGs, non–HDL-C, TG/LDL-C ratio, TG/HDL-C ratio, and non–HDL-C/HDL-C ratio among all study patients. Similar results were obtained for patients analyzed according to statin treatment. The AUCs (95% confidence interval) were 0.945 (0.884-1.000) for TG/LDL-C ratio and 0.614 (0.463-0.765) for non–HDL-C in patients without statins (P = 0.0002). The AUCs were 0.697 (0.507-0.887) for TG/LDL-C and 0.682 (0.500-0.863) for non–HDL-C in patients treated with statins. The optimal cut-off point for TG/LDL-C ratio for increased LDL-MI was 1.1 (molar ratio) regardless of statin treatment. The sensitivity and specificity of the TG/LDL-C ratio (90.0 and 93.9%, respectively) were higher than those of non–HDL-C (56.7 and 78.8%, respectively) in patients without statins. Conclusions The TG/LDL-C ratio is a reliable surrogate lipid marker of sd-LDL and superior to non–HDL-C in type 2 diabetes patients not treated with statins.

Abstract
Clinical evidence regarding eribulin treatment for patients with soft tissue sarcoma (STS) is limited to those with L-sarcoma (leiomyosarcoma and liposarcoma) who have completed at least two chemotherapies. Whether histological subtypes and treatment lines affect the efficacy and safety of eribulin for patients with STS has yet to be elucidated. The current study retrospectively reviewed patients with STS receiving eribulin at the Cancer Institute Hospital of JFCR and evaluated the prognostic factors affecting its efficacy and safety by histological diagnoses and treatment lines. A total of 41 patients with STS, including 26 with L-sarcoma, underwent eribulin treatment. Additionally, a total of and 14 patients, including 12 with L-sarcoma, received eribulin as a second-line treatment. The results revealed that patients with L-sarcoma demonstrated longer progression-free survival (PFS) rates compared with patients without L-sarcoma (4.5 vs. 2.3 months; P=0.005). Furthermore, differences in treatment line significantly affected PFS (4.5 months in second-line treatment vs. 2.4 months in later lines; P=0.037). A high number of patients with L-sarcoma received eribulin as a second-line treatment. Regarding safety, several adverse events were reported, such as neutropenia, which were more frequently observed in patients with L-sarcoma or other patients receiving eribulin as a second-line treatment. However, most adverse events were tolerable. The clinical efficacy of eribulin was increased in patients with L-sarcoma, which was similar to previous clinical trials. However, treatment lines could also affect its efficacy. When evaluating the clinical value of eribulin to STS, it is important to consider treatment lines.

Abstract
The risk of malignancy in inflammatory myopathy patients is well recognized. However, the incidence of germ cell tumor (GCT) with inflammatory myopathy is low, and most reported cases of GCT also exhibit testicular tumors. Therefore, a case of extragonadal GCT with dermatomyositis (DM) is reported in the current study to better understand this paraneoplastic syndrome. A 53-year-old man presented with bilateral cervical lymph node enlargement. A lymph node biopsy showed embryonal carcinoma, and computed tomography showed multiple lymph node and lung metastases. A period of one month after bleomycin, etoposide and cisplatin (BEP) chemotherapy, this patient developed an erythematous eruption over the extensor surfaces of bilateral fingers, or Gottron's sign and facial erythema. The patient was diagnosed with DM with a positive anti-TIF-1γ-antibody result. High-dose prednisolone was effective, and there has been no evidence of cancer recurrence for over one year. The literature review identified 17 cases of GCT with inflammatory myopathy that have been reported so far, and it was indicated that this is the first case of extragonadal GCT with DM following chemotherapy. This case highlights the importance of monitoring after the completion of cancer treatment, as distinctive dermal and muscular symptoms should cause us to consider the possibility of paraneoplastic inflammatory myopathy.

Abstract
BACKGROUND/AIM Trabectedin is a synthetic antineoplastic agent approved for advanced soft tissue sarcoma (STS) in Japan. The aim of this study was to evaluate the efficacy and safety of the Japan-approved dose of trabectedin for advanced STS. PATIENTS AND METHODS We retrospectively reviewed 38 patients with advanced STS who received salvage chemotherapy with trabectedin. RESULTS The overall response and disease control rates were 16% (5 patients) and 67% (20 patients), respectively. The median progression-free and overall survival were 7.3 and 17.8 months, respectively. There were no significant differences between patients with liposarcoma or leiomyosarcoma and those without, or between patients with TRS and those without. The most common grade 3-4 AEs were elevated transaminases and neutropenia. CONCLUSION Trabectedin 1.2 mg/m2, as the approved dose in Japan, showed similar efficacy to the dose of 1.5 mg/m2 used in Western countries. Trabectedin could be an option for advanced STS in Japan, regardless of histological subtype.

Abstract
BACKGROUND Osteoporosis is a major side effect of aromatase inhibitors (AIs), which are greatly effective in the treatment of breast cancer. However, there are no satisfactory measures against osteoporosis. In this multicenter, randomized, comparative study, we evaluate the efficacy of denosumab for preventing loss of bone mineral density (BMD) induced by adjuvant therapy with AI s in breast cancer patients with normal BMD. PATIENTS AND METHODS The bone loss-suppressing effect of denosumab will be comparatively evaluated in postmenopausal patients scheduled to receive letrozole or anastrozole as a postoperative endocrine therapy for stage I-IIIA hormone-sensitive breast cancer and a control group. Patients will be administered letrozole 2.5 mg or anastrozole 1 mg once a day, and the treatment will be continued for 5 years unless recurrence, secondary cancer, or unacceptable toxicity develops. Patients in the denosumab group will receive a subcutaneous injection of 60 mg of denosumab every 6 months. The primary endpoint is the rate of change in the lumbar spine (L1-L4) BMD, as determined by dual-energy X-ray absorptiometry (DXA), 12 months after the start of the injection. The secondary endpoints were ETHICS AND DISSEMINATION:: The protocol was approved by the institutional review boards of Kyoto Prefectural University of Medicine and all the participating faculties. Written informed consent was obtained from all patients before registration, in accordance with the Declaration of Helsinki. Results of the study will be disseminated via publications in peer-reviewed journals. TRIAL REGISTRATION Clinical Trials.gov Identifier: NCT03324932, Japan Registry of Clinical Trial (jRCT): CRB5180001.

Abstract
108 Background: Human epidermal growth factor 2 (HER2) is a potential strong tumor driver for breast (BC) and gastric cancer (GC) as well as other HER2 expressing tumors. Antibody-drug conjugates (ADC) provide wider therapeutic window by more efficient and specific drug delivery. DS-8201a is a HER2 targeting ADC of high drug to antibody ratio (7 to 8) with a novel topoisomerase I inhibitor. In preclinical studies, DS-8201a showed a broader antitumor spectrum than T-DM1, including efficacy against low HER2 expressing tumors. Current trial includes dose escalation (Part 1) and expansion (Part 2) focusing on HER2 expressing solid tumors (NCT02564900). Methods: Part 1 used a modified continuous reassessment method to identify the expansion dose in patients (pts) with BC or GC. Part 2 was designed to evaluate the safety and efficacy in 4 expansion cohorts: T-DM1 treated HER2+ BC, trastuzumab treated HER2+ GC, BC with low HER2 expressing and other HER2 expressing solid tumors. Adverse events (AEs), objective response rate (ORR) and durability of responses were assessed. Results: 89 pts were administered in total: 24 pts in Part 1 and 65 pts (BC, GC, colorectal, salivary and non-small cell lung cancer) in Part 2 with median prior therapies of 4. DS-8201a was administered up to 8.0 mg/kg in Part 1, and dose levels of 6.4 and 5.4 mg/kg IV every 3 weeks were chosen for Part 2. There was no dose limiting toxicity, and maximum tolerated dose was not reached in Part 1. The most common AEs in Part 1 and Part 2 were nausea (62%), anorexia (56%) and platelet count decreased (28%). 29% pts experienced ≥ Gr3 AEs (Gr3: 25% Gr4: 4%). The ORR and disease control rate (DCR: CR + PR + SD) are shown in the table. ORR and DCR were 40% and 90%, respectively in evaluable 73 pts including 14 low HER2 expression. One T-DM1 treated BC pt achieved CR. 4 PRs were achieved in pts with low HER2 expression. 63 pts in total are currently being treated. Median duration of treatment was ≥27 weeks in Part 1 and not reached in Part 2. Conclusions: DS-8201a was well tolerated and is remarkably active in heavily pretreated HER2 expressing cancers. Clinical trial information: NCT02564900. [Table: see text]

Abstract
HrpZ, a type three secretion system helper protein from the plant-pathogen Pseudomonas syringae, can be recognized by many plants as a defence elicitor. Responses of Arabidopsis thaliana suspension cells to different HrpZ variants were studied by electrophysiological methods and cell death assay. Purified HrpZ originating from a compatible pathogen P. syringae pv. tomato DC3000 (HrpZ(Pto)) and incompatible P. syringae pv. phaseolicola (HrpZ(Pph)) both promoted Arabidopsis cell death. As an early response, both HrpZ variants induced an increase in time dependent K(+) outward rectifying current. In contrast, the effects of HrpZ proteins on anion currents were different: HrpZ(Pph) had no effect, and HrpZ(Pto) induced an anion current increase. This suggests that the observed responses of the K(+) channels and anion channels resulted from different and separable interactions and that the interaction implied in anion current modulation is host-specific. HrpZ(Pto) and HrpZ(Pph) also had a different sequence preference in phage display screen for peptide-binding. These peptides presumably represent a part of a putative target protein in the host, and HrpZ proteins of different P. syringae pathovars might have different binding specificities to match the allelic variation between plant species. Supporting the idea that the peptide-binding region of HrpZ is important for interactions with host cell components, we found that a mutation in that region changed the anion channel response of Arabidopsis cells.

Abstract
Abstract
Background: The purpose of this study was to determine the primary chemosensitivity and prognosis among women with four common breast subtypes, Luminal A, Luminal B, HER2 and Triple negative (TN). In this study, we evaluated the response to primary chemotherapy of each subtype, reported the outcome of each subgroup after primary chemotherapy.
Method: We analyzed the outcome and characteristics of patients treated with primary chemotherapy using anthracycline and/or taxanes. Before initiation of chemotherapy, invasive carcinoma was confirmed on initial biopsy specimen obtained and hormone receptor status and HER2/neu status was also determined on this specimen. ER and PgR positivity was recognized at a cut-off of > 10% positive nuclei by immunohistochemistory (IHC). HER2/neu-positive status was defined as either 3+ by IHC or presence of gene amplification by fluorescence in situ hybridization testing. Breast cancer subtypes were defied as follow, TN (ER-, PgR-, HER2-), Luminal A (ER+ and/or PgR+, HER2-), Luminal B (ER+ and/or PgR+, HER2+), HER2 (ER-, PgR-, HER2+).
Result: Between 2000 and 2007, 639 breast cancer patients were treated with primary chemotherapy at Cancer Institute Hospital. Clinical and immunohistochemical data was available on 503 patients. Median observation period was 49.9 months (2.8-122.4). In these cases, 105 cases (20.9%) were defined as TN, 276 cases (54.9%) were defined as Luminal A, 49 cases (9.7%) were defined as Luminal B, 73 cases (14.5%) were defined as HER2, respectively. 138 patients (27.4%) received anthracycline-based regimen, 139 patients (27.6%) received taxane, 227 patients (45.1%) received taxane-anthracycline combination regimen. The pathologic complete response (pCR) rate of each group was 15.2%, 2.0%, 8.2%, 16.4%, in TN, Luminal A, Luminal B, HER2, respectively (P<0.001). The 5-yr disease free survival estimated 69.1%, 74.4%, 62.8%, 70.6% (p=0.140), and the 5-yr overall survival estimated 69.1%, 75.6%, 88.6%, 69.4% in TN, Luminal A, Luminal B, HER2, respectively (p=0.007). Mean survival time from the first recurrence was 21.1 months (95%CI 11.5-30.7), 40.6 months (95%CI 31.6-49.6), 81.8 months (95%CI 59.1-104.5), 30.0 months (95%CI 21.1-38.9), respectively (P<0.001). According to the first recurrence, most frequent visceral metastatic site of TN and HER2 patients was brain (P<0.001), and median time to brain metastasis was
13.2 months (95%CI 8.5-17.9). Surprisingly, three (21.4%) of the patients who had brain metastasis resulted in pCR by primary chemotherapy. Of note, Luminal A patients were more likely to have bone metastasis than other groups at first (p=0.003), and median time to bone metastasis was
16.3 months (95%CI 14.1-18.6).
Conclusions: With primary chemotherapy, pCR rate of TN and HER2 were higher than Luminal groups, but they developed brain metastasis early irrespective of pCR, this might contribute to their worse prognosis. In contrast, Luminal A developed bone metastasis at first, this might result in good prognosis instead of their low pCR rate.

Abstract
Altered lipid metabolism is associated with human abnormal pregnancy, such as pre-eclampsia and preterm labor, and potentially leads to fetus loss. A causative factor for the onset and progress of the systemic multifactorial syndromes associated with the pathological pregnancy is oxidized low-density lipoprotein, an active identity of which was postulated to be lysophosphatidic acid (LPA). We previously found that LPA is produced extracellularly by plasma lysophospholipase D (lysoPLD) activity of autotaxin, a tumor cell motility-stimulating protein. In this study, a convenient assay based on the choline released from endogenous substrate or exogenous lysophosphatidylcholine (LPC) was used for comparison of serum lysoPLD activity among patients with normal and abnormal pregnancy. The serum choline-producing activity was found to be mainly due to autotaxin, and dependent on its dilution rate. There was some association between low dilution dependency of serum lysoPLD activity toward an exogenous LPC and high lysoPLD activity toward endogenous substrates in cases of patients with preterm labor and pre-eclampsia. However, there was no difference in the serum level of LPC between women with normal pregnancy and those with pathological pregnancy. These results indicate that production of bioactive LPA by lysoPLD activity is elevated by an unknown mechanism that may be related to increased availability of endogenous substrates LPC, but not its concentration in human serum. If the level of LPA in blood circulation is elevated in the pathological pregnancies in vivo, it may play a role in induction and/or progression of systemic vascular dysfunction seen patients with preterm labor or pre-eclampsia.

Abstract
We investigated the influence of bacterial superantigen on the efficacies of immunosuppressive drugs on the blastogenesis of peripheral-blood mononuclear cells of 27 hemodialysis patients awaiting renal transplantation. The IC(50) values for prednisolone, methylprednisolone, cyclosporine, and tacrolimus evaluated in the superantigen-stimulated cells were significantly higher than those evaluated in concanavalin A-stimulated cells (p = 0.0002-0.018). Interleukin-2 amounts produced from superantigen-stimulated cells were significantly larger than those from concanavalin A-stimulated cells (p = 0.0363). These results suggest that superantigen attenuates the suppressive efficacies of glucocorticoids and calcineurin inhibitors by stimulating lymphocytes of hemodialysis patients awaiting transplantation to overproduce interleukin-2.

Abstract
BACKGROUND Although living donor liver transplantation (LDLT) was established as a treatment for end-stage liver disease in Japan, the indication for LDLT across an ABO-incompatible barrier remains controversial. The purpose of this study was to elucidate the role of plasmapheresis in incompatible LDLT. METHODS Eleven adult patients (seven men and four women) who underwent incompatible LDLT were enrolled in this study. Of these three patients had hepatocellular carcinoma, three chronic hepatitis C, one Wilson's disease, one autoimmune hepatitis, one chronic hepatitis B, one hemochromatosis, and one fulminant hepatic failure. The immunosuppressive regimen consisted of tacrolimus, prednisolone, mycophenolate mofetil (or cyclophosphamide), and prostaglandin E1 in all patients. Multiple plasmapheresis was performed perioperatively to reduce the recipient's antibody titers against the donor's blood type. RESULTS Plasmapheresis was useful for the reduction of the recipient's antibody titers to x 16 or lower before and after transplantation. There was no difference in transplant outcome between the 11 patients with incompatible blood group and 30 patients with identical or compatible blood groups. DISCUSSION Major postoperative complications such as intrahepatic biliary complications and hepatic necrosis may occur in incompatible transplantation. Several investigators suggested that anti-immunoglobulin (Ig) M and anti-IgG antibody titers sustained these complications. The antibody titers must be decreased sufficiently with plasmapheresis. An elevation of anti-ABO titers after transplantation may be a predictive risk factor for increased mortality and morbidity. In order to perform LDLT in a safer manner, plasmapheresis is an indispensable treatment to improve the outcome of ABO-incompatible cases.

Abstract
BACKGROUND In Japan ABO-incompatible liver transplantation has been done on >100 occasions up to 2003. However, <30% are cases involving adults. The difficultly of ABO-incompatible liver transplantation is associated with the high frequency of humoral rejection and local disseminated intravascular coagulation (DIC), leading to many postoperative complications. We report a successful case of adult ABO-incompatible liver transplantation with the use of an intrahepatic artery infusion. METHODS A 36-year-old man with Wilson disease, underwent living donor liver transplantation from an ABO-incompatible donor. The immunosuppressive therapy included multiple perioperative plasmaphereses, splenectomy, and treatment with tacrolimus, methylprednisolone, and cyclophosphamide. The dose and blood level of tacrolimus were the same as in ABO-compatible cases. In addition to these therapies, we administered an intrahepatic arterial infusion with prostaglandin (PG) E1 alone. RESULTS After perioperative plasmapheresis and cyclophosphamide, antidonor blood group antibody titers remained undiluted and without vascular complications throughout the postoperative course, but there was a tendency for bleeding that continued for 10 days after transplantation. On postoperative day 10, a reexploration was performed for intraabdominal bleeding. During another operation on postoperative day 59 a biloma was found and drained. The patient has now survived for 120 days after transplantation with normal liver function. CONCLUSIONS Beneficial effect of intrahepatic artery infusion with PGE1 seems to be useful in adult ABO-incompatible liver transplantation.

Abstract
BACKGROUND The development of hemiplegia as a result of hypoglycaemia was first described in 1928. However, the mechanism remains unclear. CASE REPORT We report a case of a 58-year-old male with diabetes, who developed left hemiplegia during a severe hypoglycaemic event. Results Diffusion-weighted magnetic resonance imaging detected an increased signal intensity in the pons, indicating that the patient's hemiplegia resulted from acute brain injury. CONCLUSIONS This report provides evidence that acute brain injury may be a cause of the neurological deficit.

Abstract
Gram-negative bacteria that are pathogenic for animals or plants utilise a specialised Type III secretion system to inject effector proteins into their eukaryotic target cells. The basis for selection of the proteins to be translocated via type III systems is still enigmatic. No clearly defined consensus amino acid sequence that could serve as a specific secretion signal has been identified, and the hypothesis that an mRNA secondary structure acts as the signal has several shortcomings. We have localised a secretion signal that is sufficient to ensure the secretion of the pilin HrpA, a substrate and an indispensable extracellular component of the type III secretion machinery of Pseudomonas syringae pv. tomato DC3000, to the first 15 codons. Transcription of hrpA starts at a single site 42 bp upstream of the first codon. Gene swapping experiments revealed that altering the continuity of the 5' non-translated leader with the region including the secretion signal radically decreased accumulation of the hrpA transcript. These results indicate that an mRNA secondary structure, possibly formed in this region, is important for efficient expression of the gene. The proposed secondary structure is not, however, indispensable for the secretion of HrpA and it does not couple secretion and translation.

Abstract
The molecular mechanisms that govern early patterning of anterior neuroectoderm (ANE) for the prospective brain region in vertebrates are largely unknown. Screening a cDNA library of Xenopus ANE led to the isolation of a Hairy and Enhancer of split- (HES)-related transcriptional repressor gene, Xenopus HES-related 1 (XHR1). XHR1 is specifically expressed in the midbrain-hindbrain boundary (MHB) region at the tailbud stage. The localized expression of XHR1 was detected as early as the early gastrula stage in the presumptive MHB region, an area just anterior to the involuting dorsal mesoderm that is demarcated by the expression of the gene Xbra. Expression of XHR1 was detected much earlier than that of other known MHB genes, XPax-2 and En-2, and also before the formation of the expression boundary between Xotx2 and Xgbx-2, suggesting that the early patterning of the presumptive MHB is independent of Xotx2 and Xgbx-2. Instead, the location of XHR1 expression appears to be determined in relation to the Xbra expression domain, since reduced or ectopic expression of Xbra altered the XHR1 expression domain according to the location of Xbra expression. In functional assays using mRNA injection, overexpression of dominant-negative forms of XHR1 in the MHB region led to marked reduction of XPax-2 and En-2 expression, and this phenotype was rescued by coexpression of wild-type XHR1. Furthermore, ectopically expressed wild-type XHR1 near the MHB region enhanced En-2 expression only in the MHB region but not in the region outside the MHB. These data suggest that XHR1 is required, but not sufficient by itself, to initiate MHB marker gene expression. Based on these data, we propose that XHR1 demarcates the prospective MHB region in the neuroectoderm in Xenopus early gastrulae.

Abstract
OBJECTIVES To study whether primary tumor thickness of stage I/II tongue carcinoma provides information about subsequent lymph node metastasis. METHODS Twenty consecutive patients with T1N0M0 or T2N0M0 tongue carcinoma were studied. Primary tumor thickness was measured with post-contrast helical computed tomography or intra-oral sonography. Cervical lymph nodes were evaluated periodically with sonography at intervals of 2-4 weeks. Sensitivity, specificity and accuracy for subsequent metastasis was calculated. RESULTS Positive sonographic findings appeared in nine nodes of nine patients during this follow-up period. Eleven patients underwent neck dissections, and nine had histopathologically positive nodes. Nine patients had no sonographic findings of metastasis during a minimum follow-up period of 20 months. Primary tumor thickness varied from 3-16 mm. Using 5 mm as a cut-off thickness, the sensitivity, specificity and accuracy for subsequent lymph node metastasis were 64, 100 and 75% respectively. CONCLUSIONS Patients with stage I/II tongue carcinoma which is more than 5 mm thick are more likely to develop lymph node metastasis.

Abstract
Orthotopic liver transplantation has been recommended for patients with disabling polycystic liver disease (PCLD). Because of the shortage of cadaveric donors, living donor liver transplantation (LDLT) has been developed as an alternative. We describe the case of a woman with PCLD as an extrarenal manifestation of autosomal-dominant polycystic kidney disease (ADPKD) who was successfully palliated by LDLT. The patient was a 48-year-old woman with abdominal distention. Computed tomography showed a massively enlarged liver containing innumerable cysts, as well as bilateral kidney cysts. Hepatic and renal functions were well preserved. Genetic analysis of the family did not exclude linkage to the PKD1 locus. Two and a half years after the first examination, the patient reported severely disabling symptoms caused by the PCLD. Living donor liver transplantation was performed using a right-lobe graft. The recipient and donor were both well 8 months after the transplantation. The excised liver weighed 7.4 kg, and the histopathology revealed multiple cysts and von Meyenburg complexes in the portal areas.

Abstract
The virulence of soft-rot Erwinia species is dependent mainly upon secreted enzymes such as pectinases, pectin lyases, and proteases that cause maceration of plant tissue. Some soft-rot Erwinia spp. also harbor genes homologous to the hypersensitive reaction and pathogenesis (hrp) gene cluster, encoding components of the type III secretion system. The hrp genes are essential virulence determinants for numerous nonmacerating gram-negative plant pathogens but their role in the virulence of soft-rot Erwinia spp. is not clear. We isolated and characterized 11 hrp genes of Erwinia carotovora subsp. carotovora. Three putative sigmaL-dependent Hrp box promoter sequences were found. The genes were expressed when the bacteria were grown in Hrp-inducing medium. The operon structure of the hrp genes was determined by mRNA hybridization, and the results were in accordance with the location of the Hrp boxes. An E. carotovora strain with mutated hrcC, an essential hrp gene, was constructed. The hrcC- strain was able to multiply and cause disease in Arabidopsis, but the population kinetics were altered so that growth was delayed during the early stages of infection.

Abstract
Recently, hepatitis virus-associated chronic hepatitis or cirrhosis has been suggested to be involved in the pathogenesis of cholangiocarcinoma (CC). A 52-year-old man was diagnosed as CC with a background of hepatitis B virus (HBV)-dependent cirrhosis. A minute hepatic tumor was found during the follow-up, and was diagnosed as CC on percutaneous biopsy. The patient died of hepatic failure and an autopsy revealed the tumor to be a well to moderately differentiated adenocarcinoma. An immunohistological analysis of HBV X gene-encoded protein (HBX) was neither detected in the cancerous nor in the noncancerous tissue. No oncogenic role of the virus was verified in this case.

Abstract
The Hrp pilus, composed of HrpA subunits, is an essential component of the type III secretion system in Pseudomonas syringae. We used electron microscopy (EM) and immunocytochemistry to examine production of the pilus in vitro from P. syringae pv. tomato strain DC3000 grown under hrp-inducing conditions on EM grids. Pili, when labeled with antibodies to HrpA, developed rapidly in a nonpolar manner shortly after the detection of the hrpA transcript and extended up to 5 microm into surrounding media. Structures at the base of the pilus were clearly differentiated from the basal bodies of flagella. The HrpZ protein, also secreted via the type III system, was found by immunogold labeling to be associated with the pilus in vitro. Accumulation and secretion of HrpA and HrpZ were also examined quantitatively after the inoculation of wild-type DC3000 and hrpA and hrpZ mutants into leaves of Arabidopsis thaliana. The functional pilus crossed the plant cell wall to generate tracks of immunogold labeling for HrpA and HrpZ. Mutants that produced HrpA but did not assemble pili were nonpathogenic, did not secrete HrpA protein, and were compromised for the accumulation of HrpZ. A model is proposed in which the rapidly elongating Hrp pilus acts as a moving conveyor, facilitating transfer of effector proteins from bacteria to the plant cytoplasm across the formidable barrier of the plant cell wall.

Abstract
Collectins, C-type (Ca2+-dependent) animal lectins with both collagenous and carbohydrate recognition domains, function as opsonins against pathogens. We previously described an N-acetylglucosamine (GlcNAc)-binding lectin (ficolin/P35) with a collagen- and a fibrinogen-like sequence present in human serum. In this report we show that ficolin/P35 can serve as an opsonin and enhance the clearance of pathogens having surface GlcNAc. Ficolin/P35 bound to an Ra chemotype strain of Salmonella typhimurium (TV119) which has an exposed GlcNAc at the non-reducing termini of the polysaccharide. On the other hand, ficolin/P35 did not bind to LT2, a smooth type strain of S. typhimurium with additional O-polysaccharides covering GlcNAc. Ficolin/P35 enhanced the uptake of TV119 by monocytes or polymorphonuclear leukocytes but had no opsonic activity towards LT2. These results suggest that, like collectins, ficolin/P35 is a collagenous lectin which has a role in innate immunity against certain pathogenic organisms by acting as an opsonin. We prepared monoclonal antibodies against ficolin/P35 and developed an enzyme-linked immunosorbent assay (ELISA) for measuring ficolin/P35 concentrations in humans. The mean serum concentration of ficolin/P35 from 130 normal individuals was estimated to be 13.7 microg/ml.

Abstract
We studied whether gemfibrozil and clofibric acid alter isoprenoid lipid synthesis in rat hepatocytes. After incubation of the cells with the agent for 74 hr, [(14)C]acetate or [(3)H]mevalonate was added, and the cells were further incubated for 4 hr. Gemfibrozil and clofibric acid increased ubiquinone synthesis from [(14)C]acetate and [(3)H]mevalonate. The effect of gemfibrozil was greater than that of clofibric acid. Also, gemfibrozil decreased dolichol synthesis from [(14)C]acetate and [(3)H]mevalonate. However, clofibric acid increased dolichol synthesis from [(3)H]mevalonate. Gemfibrozil decreased cholesterol synthesis from [(14)C]acetate and [(3)H]mevalonate. Clofibric acid decreased cholesterol synthesis from [(14)C]acetate, but did not affect synthesis from [(3)H]mevalonate. These results suggest that both agents, at different rates, activate the synthetic pathway of ubiquinone, at least from mevalonate. Gemfibrozil may inhibit the synthetic pathway of dolichol, at least from mevalonate. Contrary to gemfibrozil, clofibric acid may activate the synthetic pathway of dolichol from mevalonate. Gemfibrozil may inhibit the synthetic pathway of cholesterol from mevalonate in addition to the pathway from acetate to mevalonate inhibited by both agents.

Abstract
Plant pathogenic Pseudomonas syringae strains harbour a type III secretion pathway suggested to be involved in the delivery of effector proteins from the bacteria into plant cells. During plant interaction, the bacteria apparently produce surface appendages, termed Hrp pili, that are indispensable for the secretion process. We have created an insertion mutation library, as well as deletion mutations to hrpA, the structural gene encoding Hrp pilin. Analysis of the mutants revealed gene regions important for hrpA expression, pilus assembly and pilus-dependent autoagglutination of the bacteria. The majority of insertions in the amino-terminal half of the pilin were tolerated without bacterial interaction with plants being affected, while the carboxy-terminus appeared to be needed for pilus assembly. Insertions in the 5' non-translated region and the first codons within the open reading frame affected mRNA production or stability and abolished protein production.

Abstract
Effects of acute and chronic blockade of endothelin ET(A) or ET(B) receptors on renal hemodynamics and function were investigated using deoxycorticosterone acetate (DOCA)-salt-induced hypertensive rats. At 4 weeks after initiating DOCA-salt treatment, intravenous bolus injection of ABT-627 (1 mg/kg), a selective ET(A) receptor antagonist, produced a sustained and significant hypotension, which was accompanied by potent renal vasodilation. When the selective ET(B) receptor antagonist A-192621 (3 mg/kg) was intravenously administered, there were marked decreases in renal blood flow and glomerular filtration rate, and increases in renal vascular resistance. A slight hypertensive effect was observed after the injection of A-192621. Next, we examined the effects of chronic treatment with ABT-627 (10 mg/kg/d, p.o., b.i.d.) or A-192621 (30 mg/kg/d, p.o., b.i.d.) for 2 weeks on renal function of animals at 2 weeks after initiating DOCA-salt treatment. In the 2-week-treated DOCA-salt animals, the levels of creatinine clearance (Ccr), urinary excretion of protein (Uprotein V) and blood urea nitrogen (BUN) were not significantly different compared with those of sham-operated control animals. These parameters did show statistically significant differences over the 3 to 4 weeks treatment period, between the DOCA-salt and the control animals (decrease in Ccr, and increase in Uprotein V and BUN in DOCA-salt rats), thereby indicating the gradual establishment of renal dysfunction in this hypertensive model. The DOCA-salt-induced changes in renal functional parameters were markedly attenuated by daily administration of ABT-627. In contrast, treatment with A-192621 augmented the above renal dysfunction. Our findings clearly indicate that selective blockade of the ET(B) receptor is detrimental to renal hemodynamics and the function of the hypertensive condition, and support the view that a selective ET(A) receptor antagonist is useful for treatment of subjects with mineralocorticoid-dependent hypertension.

Abstract
Transposons are mobile genetic elements and have been utilized as essential tools in genetics over the years. Though highly useful, many of the current transposon-based applications suffer from various limitations, the most notable of which are: (i) transposition is performed in vivo, typically species specifically, and as a multistep process; (ii) accuracy and/or efficiency of the in vivo or in vitro transposition reaction is not optimal; (iii) a limited set of target sites is used. We describe here a genetic analysis methodology that is based on bacteriophage Mu DNA transposition and circumvents such limitations. The Mu transposon tool is composed of only a few components and utilizes a highly efficient and accurate in vitro DNA transposition reaction with a low stringency of target preference. The utility of the Mu system in functional genetic analysis is demonstrated using restriction analysis and genetic footprinting strategies. The Mu methodology is readily applicable in a variety of current and emerging transposon-based techniques and is expected to generate novel approaches to functional analysis of genes, genomes and proteins.

Abstract
Three cases of non-traumatic intracavernous aneurysms that gave rise to massive epistaxis and required operative intervention, are reported. This is a rare but serious cause of epistaxis, because delayed diagnosis and management can lead to repeated bleedings and even to death. It is important, therefore, to diagnose the source of epistaxis and treat it as soon as possible. In our three patients, an emergency angiography enabled us to diagnose an aneurysm in the cavernous sinus. These aneurysms were located in the C3 or C4 portion of the internal carotid artery and were 3-5 mm in diameter. The projections of these aneurysms were infero-medial, antero-inferior, and lateral, respectively. All three patients underwent emergent surgery. Neck clipping of the aneurysm was performed in two patients, and gradual occlusion of the internal carotid artery in the third patient. Emergency surgery successfully prevented further episodes of epistaxis in all three patients.

Abstract
A 25-year-old woman who underwent surgical removal of a right frontal meningeal mesenchymal chondrosarcoma in 1980 manifested abdominal pain and progressive anemia after a traffic accident in April 1997. CT disclosed a well-enhanced solid mass 2.5 cm in diameter with internal calcific deposits at the tail of the pancreas and a surrounding hematoma of 5.5 cm in diameter. Surgical resection revealed a ruptured metastatic mesenchymal chondrosarcoma of the pancreas.

Abstract
We describe the first reported case of an intracortical hemangioma of the mandible in a 13-year-old Japanese girl. Panoramic radiography and CT demonstrated a small osteolytic lesion which had expanded and thinned the cortex at the inferior border of the left mandible. The lesion enhanced on post-contrast T1-weighted MRI. The diagnosis was confirmed by histopathology following block excision. Intracortical hemangioma should be considered in the differential diagnosis of radiolucent lesions orf the mandible

Abstract
We investigated the involvement of actions mediated by endothelin-A (ETA) and endothelin-B (ETB) receptors in the pathogenesis of deoxycorticosterone acetate (DOCA)-salt-induced hypertension in rats. Two weeks after the start of DOCA-salt treatment, rats were given ABT-627 (10 [mg/kg]/d), a selective ETA receptor antagonist; A-192621 (30 [mg/kg]/d), a selective ETB receptor antagonist; or their vehicle for 2 weeks. Uninephrectomized rats without DOCA-salt treatment served as controls. Treatment with DOCA and salt for 2 weeks led to a mild but significant hypertension; in vehicle-treated DOCA-salt rats, systolic blood pressure increased markedly after 3 to 4 weeks. Daily administration of ABT-627 for 2 weeks almost abolished any further increases in blood pressure, whereas A-192621 did not affect the development of DOCA-salt-induced hypertension. When the degree of vascular hypertrophy of the aorta was histochemically evaluated at 4 weeks, there were significant increases in wall thickness, wall area, and wall-to-lumen ratio in vehicle-treated DOCA-salt rats compared with uninephrectomized control rats. The development of vascular hypertrophy was markedly suppressed by ABT-627. In contrast, treatment with A-192621 significantly exaggerated these vascular changes. In vehicle-treated DOCA-salt rats, renal blood flow and creatinine clearance decreased, and urinary excretion of protein, blood urea nitrogen, fractional excretion of sodium, and urinary N-acetyl-beta-glucosaminidase activity increased. Such damage was overcome by treatment with ABT-627 but not with A-192621; indeed, the latter agent led to worsening of the renal dysfunction. Histopathologic examination of the kidney in vehicle-treated DOCA-salt rats revealed tubular dilatation and atrophy as well as thickening of small arteries. Such damage was reduced in animals given ABT-627, whereas more severe histopathologic changes were observed in A-192621-treated animals. These results strongly support the view that ETA receptor-mediated action plays an important role in the pathogenesis of DOCA-salt-induced hypertension. On the other hand, it seems likely that the ETB receptor-mediated action protects against vascular and renal injuries in this model of hypertension. A selective ETA receptor antagonist is likely to be useful for treatment of subjects with mineralocorticoid-dependent hypertension, whereas ETB-selective antagonism alone is detrimental to such cases.

Abstract
We studied whether the peroxisomal proliferation, induction of 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) and activation of cholesterol synthesis by gemfibrozil shown in whole body (Hashimoto F., Ishikawa T., Hamada S. and Hayashi H., Biochemical. Pharm., 49, 1213-1221 (1995)) is also detected at a culture cell level, and we made a comparative analysis of the effects of clofibric acid. Gemfibrozil at 0.25 mM increased the activity of some peroxisomal enzymes (catalase and the cyanide-insensitive fatty acyl-CoA oxidizing system) after incubation for 72 h. However, contrary to whole body experiments, gemfibrozil decreased the activity of HMG-CoA reductase and cholesterol synthesis from [14C]acetate. At 1 mM, gemfibrozil decreased not only the activity of HMG-CoA reductase and cholesterol synthesis, but also the protein content of the cells and peroxisomal enzyme activity, indicating nonspecific inhibition at this concentration. Clofibric acid (0.25 and 1 mM) increased the activity of peroxisomal enzymes, but decreased the activity of HMG-CoA reductase and cholesterol synthesis. With respect to the direct effect on HMG-CoA reductase in the cell homogenate, gemfibrozil at 0.25 mm did not affect the activity, but it clearly inhibited the activity at 2 mM and above. Clofibric acid at 2 mM hardly affected the activity, but it clearly decreased the activity at 5 mM and over. That is, gemfibrozil directly inhibited the activity more strongly than clofibric acid. The direct inhibition of the enzyme itself required higher concentrations of both agents than did inhibition at the culture cell level. These results suggest that the cytotoxicity of gemfibrozil is greater than that of clofibric acid, and that gemfibrozil, as well as clofibric acid, can induce peroxisomal enzymes in the culture cell level. In contrast to whole body results, gemfibrozil may suppress cholesterol synthesis from [14C]acetate through the inhibition of HMG-CoA reductase at the culture cell level. The decreases in the reductase activity caused by gemfibrozil and clofibric acid at the culture cell level may not be caused by the direct inhibition of the enzyme.

Abstract
The effects of FR139317((R)2-[(R)-2-[(S)-2-[[1-(hexahydro-1H-azepinyl)]carb onyl] amino-4-methyl-pentanoyl] amino-3-[3-(1-methyl-1H-indoyl)]propionyl]-amino-3-(2-pyridyl)prop ionic acid), an endothelin ET(A) receptor antagonist, on systemic and renal haemodynamic responses and excretory responses to chronic or acute nitric oxide (NO) synthase inhibition with NG-nitro-L-arginine (NOARG) have been examined. An intravenous bolus injection of FR139317 (10 mg kg(-1)) to chronic NO-deficient hypertensive rats (2.74 mM NOARG in drinking water for 4 weeks) elicited only a slight decrease in mean arterial pressure (MAP), to the same extent as seen in normotensive control rats. Injection of this drug induced no alteration of the renal haemodynamics of this chronic hypertensive model. Urine formation in control rats was significantly reduced by administration of FR139317. No significant decrease in urine formation was observed in the chronic NO-deficient rats. Acute intravenous injection of NOARG (5 mg kg(-1)) induced a gradual and significant increase in MAP, with a significant decrease in renal blood flow. A slight but insignificant diuretic effect was observed. In animals pretreated with FR139317 (10 mg kg(-1) i.v.) NOARG induced a significantly less potent increase in MAP, whereas similar renal haemodynamic responses to NOARG were observed. In contrast to the FR139317-untreated group, urine formation tended to decrease after administration of NOARG. These results suggest that endothelin, via the ET(A) receptor, contributes to the systemic pressor response to acute NO synthase inhibition, although renal vasoconstriction and functional changes induced by acute NO synthase inhibition are independent of ET(A) receptor-related effects. These results imply that action of endothelin via the ET(A) receptor is not involved in the maintenance of sustained hypertension induced by chronic NO synthase inhibition.
