Abstract
BACKGROUND We have previously found that pioglitazone attenuates inflammation in the left main trunk of coronary artery (LMT), evaluated as target-to-background ratio (TBR) by 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in patients with impaired glucose tolerance or type 2 diabetes. OBJECTIVES We assessed which clinical variables could predict the change in TBR in the LMT after 4-month add-on therapy with oral hypoglycemic agents (OHAs). METHODS A total of 38 type 2 diabetic patients with carotid atherosclerosis who had already received OHAs except for pioglitazone was enrolled. At baseline and 4 months after add-on therapy with pioglitazone or glimepiride, all patients underwent 75 g oral glucose tolerance test, blood chemistry analysis, and FDG-PET/CT. RESULTS Fasting plasma glucose, 30-, 60-, 90-, 120-minutes postload plasma glucose, HbA1c, and LMT-TBR values were significantly decreased by add-on therapy, whereas high-density lipoprotein-cholesterol and adiponectin levels were increased. Increased serum levels of pigment epithelium-derived factor (PEDF), a marker of insulin resistance and non-use of aspirin at baseline could predict the favorable response of LMT-TBR to add-on therapy. Moreover, Δ120-minutes postload plasma glucose and ΔPEDF were independent correlates of ΔLMT-TBR. CONCLUSIONS Our present study suggests that 120-minutes postload plasma glucose and PEDF values may be markers and potential therapeutic targets of coronary artery inflammation in type 2 diabetic patients. CLINICAL TRIAL REGISTRATION URL: http://clinicaltrials.gov . Unique identifier: NCT00722631. New markers for diabetes and CAD is on the horizon! Two-hour postload plasma glucose and pigment epithelium derived factor are markers of coronary artery inflammation in type 2 diabetic patients.

Abstract
Viscosity, a crucial characteristic for rice palatability, is affected by endosperm characters. We compared correlations between differences in viscosity of japonica rice with various palatability and endosperm characters. Changes in apparent amylose and protein contents (AAC% and PC%, respectively) and amylopectin side-chain distribution and the relationship of these traits with palatability were investigated in superior and inferior spikelets of good cultivars with low amylose content from Hokkaido and common cultivars from northeastern Japan, using rapid visco analyzer characteristics and rice-grain microstructures. Significant differences occurred in PC%, AAC%, breakdown, setback, peak time, and pasting temperature of different cultivars and grain positions. Amylopectin components showed remarkable differences in grain surfaces, surface layers, and section structure between the grain varieties. Hokkaido cultivars showed better viscosity than northeastern cultivars, particularly initial stage grains. Correlation analysis indicated viscosity was mainly AAC%-dependent, whereas differences in endosperm characteristics between spikelet positions were mainly due to grain-filling temperature.

Abstract
Trimethylamine (TMA), an intestinal microflora-dependent metabolite formed from phosphatidylcholine- and L-carnitine-rich food, such as red meat, is further converted to trimethylamine-N-oxide (TMAO), which could play a role in cardiometabolic disease. Red meat-derived products are one of the major environmental sources of advanced glycation end products (AGEs) that may also contribute to the pathogenesis of cardiometabolic disorders through the interaction with receptor for AGEs (RAGE). However, the relationship among AGEs, soluble form of RAGE (sRAGE) and TMAO in humans remains unclear. Non-diabetic subjects underwent a physical examination, determination of blood chemistry and anthropometric variables, including AGEs, sRAGE, TMA and TMAO. Multiple regression analyses revealed that HbA1c, uric acid and AGEs were independently associated with log TMA, whereas log AGEs to sRAGE ratio and statin non-use were independently correlated with log TMAO. Our present findings indicated that AGEs to sRAGE ratio was correlated with log TMAO, a marker of cardiometabolic disorders.

Abstract
Abstract
<Background>
The information presented herein extends our recent study of TTT (Trial for Triplet Antiemetic Therapy).
One of our main clinical questions has been whether a 2nd generation serotonin receptor antagonist (5-HT3ra) would be superior to 1st generation 5-HT3ra when administering triplet antiemetic therapy for the prevention of chemotherapy induced nausea & vomiting (CINV), since a prior Japanese trial demonstrated palonosetron to be superior to granisetron for controlling the delayed phase of CINV induced by highly emetogenic chemotherapy (HEC) and to doublet antiemetic therapy including dexamethasone for anthracycline and cyclophosphamide containing regimens (AC).
<Objectives>
In this study, we assessed the efficacies of 1st and 2nd generation 5-HT3ra agents for use as triplet antiemetic therapy for AC, by monitoring CINV, focusing especially daily CR in the delayed phase.
<Material and method>
Between 2012 and 2015, 491 women with breast cancer receiving AC were recruited from 11 institutions in Japan, and randomly assigned to either single-dose palonosetron (0.75mg) or granisetron (40μg/kg) prior to chemotherapy on day 1, both with dexamethasone (9.9 mg intravenously) and aprepitant (125mg orally) on day 1 followed by additional doses (80mg orally) on days 2 and 3. Age, institution and habitual alcohol intake were used as stratification factors. The primary endpoint was a complete response (CR). Statistical analysis was done by Mantel-Haenszel Method. This trial was registered with UMIN000007882.
<Results>
All 491 patients were included in efficacy analyses (ITT): 246 patients in the palonosetron group and 245 in the granisetron group. We previously reported that the difference in CR during the delayed phase, i.e. 24 hours after the administration of AC, did not reach statistical significance (53.8% vs 58.5%) in MASCC 2016. However, daily CR in the palonosetron group was much higher than that in the granisetron group after 48 hours.
<Conclusions>
Palonosetron showed better efficacy in controlling CINV during the late period of the delayed phase, i.e. 48 hours after AC administration, than granisetron as triplet antiemetic therapy for AC.
<Considerations>
The pattern of CINV reportedly shows two peaks including an acute phase caused by serotonin and a delayed phase caused by substance P, though the pattern of CINV with triplet antiemetic therapy administration might be different if the suppression of each of these peaks were to be achieved more efficiently. CINV may not be divided into two phases in the future, or the borderline area between the acute and delayed phases may require revision. The analysis of the late period of the delayed phase was ad hoc in this trial. However, when conducting studies related to CINV, it might be worthwhile to revise the borderline area between the two phases of CINV to facilitate elucidating the mechanisms underlying this potentially debilitating side effect of chemotherapy.

Abstract
Objective—
Endothelial dysfunction is an initial step in atherosclerotic cardiovascular disease. However, involvement of vascular inflammation in endothelial dysfunction is not fully investigated in humans because of the lack of diagnostic modality to noninvasively evaluate vascular inflammation. We assessed the relationship between endothelial function and vascular inflammation evaluated by [
18
F]-fluorodeoxyglucose-positron emission tomography/computed tomographic imaging.
Approach and Results—
We examined endothelial function and vascular inflammation by flow-mediated dilation (FMD) of the brachial artery and [
18
F]-fluorodeoxyglucose-positron emission tomography/computed tomographic imaging of carotid arteries, respectively, in 145 subjects (95 men and 50 women; mean age, 61.8±9.5 years) who underwent a risk-screening test for cardiovascular disease in Kurume University Hospital. Vascular inflammation was measured by blood-normalized standardized uptake value, known as a target:background ratio (TBR). We investigated whether absolute changes from baseline of %FMD after antihypertensive treatment for 6 months (Δ%FMD) were correlated with those of TBR in 33 drug-naive patients with essential hypertension. Multiple logistic regression analysis revealed that age (odds ratio, 1.767 for 10-year increase), male sex (odds ratio, 0.434), low-density lipoprotein-cholesterol (odds ratio, 1.630 for 26-mg/dL increase), and TBR values (odds ratio, 1.759 for 0.2 increase) were independently associated with %FMD in 145 patients. There was an inverse correlation between Δ%FMD and ΔTBR; ΔTBR was a sole independent associate of Δ%FMD in hypertensive patients (
r
=−0.558;
P
<0.001).
Conclusions—
The present study showed that vascular inflammation in the carotid arteries evaluated by [
18
F]-fluorodeoxyglucose-positron emission tomography/computed tomography was one of the independent correlates of decreased %FMD, thus suggesting the association of vascular inflammation with endothelial dysfunction in humans.

Abstract
The aim of this study was to estimate the relieving effect of music intervention on preoperative anxiety by using heart rate variability (HRV) analysis. In this randomized controlled trial, 86 adult patients were scheduled to undergo impacted tooth extraction under intravenous sedation and local anesthesia and were classified as either fearful or nonfearful based on a questionnaire. Thereafter, the patients were subdivided into 2 groups: those who listened to music from the time that they arrived at the outpatient clinic until immediately before entering the operating room and those who did not listen to music. The effect of music intervention was evaluated by assessing 1) the low-frequency/high-frequency ratio of HRV, in which positive changes indicate increased sympathetic nervous activity, and 2) the coefficient of component variance for high frequency, in which positive changes indicate increased parasympathetic nervous activity, assessed by means of HRV analysis. Subjective preoperative anxiety was evaluated on a visual analog scale. For fearful patients, the mean magnitude of low-frequency/high frequency changes from baseline among those who listened to music was significantly lower as compared with those who did not listen to music (in the private room: -1.45 ± 1.88 vs. 1.05 ± 1.88, P = 0.0096, 95% confidence interval of effect size = -4.52 to -0.48, Cohen's d = -0.75; in the operating waiting room: -2.18 ± 2.39 vs. -0.10 ± 3.37, P = 0.011, 95% confidence interval of effect size = -3.94 to -0.22, Cohen's d = -0.71, respectively). Visual analog scale scores were also significantly different. Coefficient of component variance for high frequency and heart rate did not differ significantly between the 2 groups. From the perspective of autonomic nervous activity, music intervention is useful for relieving anxiety in patients with dental fear before they enter a dental outpatient operating room. Music intervention may relieve anxiety by reducing sympathetic nervous activity, while parasympathetic nervous activity is not involved (UMIN000016882). Knowledge Transfer Statement: The results of this study revealed that music intervention is useful for clinicians when planning preoperative anxiety management of patients with dental fear who undergo impacted tooth extraction under intravenous sedation and local anesthesia. As a bridging intervention, music intervention enables stress management to continue uninterrupted from the patient's arrival at the dental outpatient clinic to intravenous sedation until completion of the dental surgery. With consideration of cost-effectiveness, absence of adverse physical effects, immediate effect, safety in terms of not using drugs, and lack of concerns about recovery, this information could lead to more appropriate decisions regarding anxiety management in dentistry.

Abstract
BACKGROUND Reduced gray matter volumes in the superior temporal gyrus (STG) have been reported in patients with schizophrenia. Such volumetric abnormalities might denote alterations in cortical thickness, surface area, local gyrification or all of these factors. The STG can be anatomically divided into five subregions using automatic parcellation in FreeSurfer: lateral aspect of the STG, anterior transverse temporal gyrus of Heschl gyrus (HG), planum polare (PP) of the STG, planum temporale (PT) of the STG and transverse temporal sulcus. METHODS We acquired magnetic resonance imaging (MRI) 3T scans from 40 age- and sex-matched patients with schizophrenia and 40 healthy subjects, and the scans were automatically processed using FreeSurfer. General linear models were used to assess group differences in regional volumes and detailed thickness, surface area and local gyrification. RESULTS As expected, patients with schizophrenia had significantly smaller bilateral STG volumes than healthy subjects. Of the five subregions in the STG, patients with schizophrenia showed significantly and marginally reduced volumes in the lateral aspect of the STG and PT of the STG bilaterally compared with healthy subjects. The volumetric alteration in bilateral lateral STG was derived from both the cortical thickness and surface area but not local gyrification. There was no significant laterality of the alteration in the lateral STG between patients and controls and no correlation among the structures and clinical characteristics. CONCLUSIONS These findings suggest that of five anatomical subregions in the STG, the lateral STG is one of the most meaningful regions for brain pathophysiology in schizophrenia.

Abstract
CONTEXT Body fat distribution and inflammation may play a role in metabolic derangements and cardiovascular disease in obesity. OBJECTIVE The aim of this study is to investigate clinical and biochemical factors associated with area and metabolic activity in the visceral and subcutaneous adipose tissues (VAT and SAT). PARTICIPANTS (18)F-fluorodeoxyglucose-positron emission tomography and computed tomography imaging was performed in 251 consecutive subjects (62.6 ± 9.3 y) for risk screening. MAIN OUTCOME MEASURES We examined which clinical, anthropometric, metabolic, and inflammatory variables including advanced glycation end products (AGEs) and pigment epithelium-derived factor (PEDF) were independently associated with area and metabolic activity in VAT and SAT. Adipose tissue area was determined with computed tomography, whereas metabolic activity was assessed by (18)F-fluorodeoxyglucose uptake expressed as a target to background ratio (TBR) of blood-normalized standardized uptake. RESULTS Serum levels of AGEs and PEDF were 9.81 ± 3.21 U/mL and 14.0 (range 10.8-17.7) μg/mL, respectively. Although the area in VAT and SAT was associated with waist circumference and sex, each adipose tissue area and TBR had different metabolic risk profiles. The TBR value in VAT was higher than that in SAT. In a multiple stepwise regression analysis, AGEs and medication for hypertension were independently associated with VAT TBR (R(2) = 0.102), whereas medication for diabetes, mean intima-media thickness, AGEs, and PEDF were the independent correlates of SAT TBR (R(2) = 0.132). CONCLUSIONS The present study demonstrated that area and metabolic activity in VAT and SAT could be differently regulated, suggesting the involvement of AGEs and PEDF in adipose tissue inflammation.

Abstract
OBJECTIVES The aim of this study was to compare the effect of pioglitazone with glimepiride on coronary arterial inflammation with serial (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) combined with computed tomography (CT) angiography. BACKGROUND Recent studies have shown that FDG-PET combined with CT is a reliable tool to visualize and quantify vascular inflammation. Although pioglitazone significantly prevented the progression of coronary atherosclerosis and reduced the recurrence of myocardial infarction in patients with type 2 diabetes mellitus (DM), it remains unclear whether pioglitazone could attenuate coronary artery inflammation. METHODS Fifty atherosclerotic patients with impaired glucose tolerance or type 2 DM underwent determination of blood chemistries, anthropometric and inflammatory variables, and FDG-PET/CT angiography, and then were randomized to receive either pioglitazone or glimepiride for 16 weeks. Effects of the treatments on vascular inflammation of the left main trunk were evaluated by FDG-PET/CT angiography at baseline and end of the study. Vascular inflammation of the left main trunk was measured by blood-normalized standardized uptake value, known as a target-to-background ratio. RESULTS Three patients dropped out of the study during the assessment or treatment. Finally, 25 pioglitazone-treated patients and 22 glimepiride-treated patients (37 men; mean age: 68.1 ± 8.3 years; glycosylated hemoglobin: 6.72 ± 0.70%) completed the study. After 16-week treatments, fasting plasma glucose and glycosylated hemoglobin values were comparably reduced in both groups. Changes in target-to-background ratio values from baseline were significantly greater in the pioglitazone group than in the glimepiride group (-0.12 ± 0.06 vs. 0.09 ± 0.07, p = 0.032), as well as changes in high-sensitivity C-reactive protein (pioglitazone vs. glimepiride group: median: -0.24 [interquartile range (IQR): -1.58 to -0.04] mg/l vs. 0.08 [IQR: -0.07 to 0.79] mg/l, p = 0.031). CONCLUSIONS Our study indicated that pioglitazone attenuated left main trunk inflammation in patients with impaired glucose tolerance or DM in a glucose-lowering independent manner, suggesting that pioglitazone may protect against cardiac events in patients with impaired glucose tolerance or DM by suppressing coronary inflammation.

Abstract
CONTEXT Excess visceral fat is associated with chronic systemic inflammation and cardiovascular complications. Pioglitazone has been reported to variably influence visceral fat volume; however, its effect on metabolic activity of the visceral fat remains uncharacterized. OBJECTIVE The aim of this study was to assess the effects of pioglitazone on glucose metabolism of fat tissue by using (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) and computed tomography imaging. DESIGN, SETTING, AND PARTICIPANTS FDG-PET and computed tomography imaging were performed in 56 patients with impaired glucose tolerance or type 2 diabetes mellitus; lipid and glycemic profiles and inflammatory biomarkers were obtained in all patients. These patients were randomized to treatment with either pioglitazone or glimepiride for 16 weeks. MAIN OUTCOME MEASURES The metabolic activity of the visceral fat tissues as assessed by FDG uptake was expressed as a target-to-background ratio (TBR) of blood-normalized standardized uptake value. RESULTS The study was completed in 32 pioglitazone-treated and 21 glimepiride-treated patients (40 men and 13 women; mean age, 67.7 ± 8.1 y; body mass index, 25.0 ± 3.6 kg/m(2); glycated hemoglobin, 6.78 ± 0.70%). Both treatments were well-tolerated and comparably improved glycemic control. At baseline, visceral fat exhibited a higher TBR value than subcutaneous fat (0.55 ± 0.14 vs 0.30 ± 0.07, P < .001). Pioglitazone, but not glimepiride, significantly decreased the visceral fat volume (130.5 ± 53.0 to 122.1 ± 51.0 cm(2), P = .013) and TBR values (0.57 ± 0.16 to 0.50 ± 0.11, P = .007). Neither pioglitazone nor glimepiride treatment showed any effect on the volume or TBR values of subcutaneous fat. After 16 weeks of treatment with pioglitazone, reduction in visceral fat TBR was correlated to the increase in high-density lipoprotein cholesterol levels. CONCLUSIONS Our study indicated that pioglitazone decreased the visceral fat volume and its metabolic activity in patients with impaired glucose tolerance or type 2 diabetes mellitus. The beneficial effects of pioglitazone on visceral fat may be independent of its glucose-lowering effect.

Abstract
OBJECTIVE Advanced glycation end products (AGEs) evoke inflammatory reactions, contributing to the development and progression of atherosclerosis. We investigated the relationship between serum AGE level and vascular inflammation. RESEARCH DESIGN AND METHODS The study involved 275 outpatients at Kurume University, Japan (189 males and 86 females; mean age 61.2 ± 8.8 years) who underwent complete history and physical examinations and determinations of blood chemistry and anthropometric variables, including AGEs. Serum AGE level was examined by enzyme-linked immunosorbent assay. Vascular [(18)F]fluorodeoxyglucose (FDG) uptake, an index of vascular inflammation, was measured as blood-normalized standardized uptake value, known as the target-to-background ratio (TBR), by FDG-positron emission tomography (FDG-PET). Furthermore, we examined whether the changes in serum AGE level after treatment with oral hypoglycemia agents (OHAs) were correlated with those of TBR in another 18 subjects whose AGE value was >14.2 units/mL (mean ± 2 SD). RESULTS Mean serum AGE level and carotid TBR values were 9.15 ± 2.53 and 1.43 ± 0.22 units/mL, respectively. Multiple stepwise regression analysis revealed that TBR was independently correlated with AGEs (P < 0.001), carotid intima-media thickness (P < 0.01), and BMI (P < 0.02). When age- and sex-adjusted AGE values stratified by TBR tertiles were compared using ANCOVA, a significant trend was observed (P < 0.01). In addition, the changes in AGEs after OHA treatment were positively (r = 0.50, P < 0.05) correlated with those in TBR value. CONCLUSIONS The current study reveals that serum AGE level is independently associated with vascular inflammation evaluated by FDG-PET, suggesting that circulating AGE value may be a biomarker that could reflect vascular inflammation within an area of atherosclerosis.

Abstract
BACKGROUND Aortic root replacement (ARR) combined with aortic arch replacement (AAR) is an invasive procedure even in elective cases. Nevertheless, such combined operations are often mandatory in acute type A aortic dissection. We examined whether emergency operation might have further incremental risks compared with elective surgery in this type of operations. METHODS Forty-six cases of ARR combined with AAR were divided into 2 groups, the emergency (EM) group and the elective (EL) group. The EM group consisted of 10 cases of acute type A aortic dissection, whereas the EL group of 36:23 of chronic aortic dissection and 13 of true aneurysm. RESULTS There were no statistical differences between the 2 groups in the durations of aortic crossclamp, selective cerebral perfusion and cardiopulmonary bypass. The incidences in the EM and EL groups were as follows:in-hospital death; 0 vs 3( 8%), respiratory failure; 4 (40%) vs 14 (39%), renal failure; 0 vs 6 (17%), IABP requirement; 1 (10%) vs 3 (8%), and cerebral infarction; 0 vs 1 (3%), respectively. CONCLUSION Early surgical results of emergency ARR combined with AAR were almost equal to those in elective surgery.

Abstract
OBJECTIVE Pigment epithelium-derived factor (PEDF) could play a protective role against atherosclerosis. However, there is no clinical study to examine the relationship between serum level of PEDF and atherosclerosis in humans. METHODS/RESULTS The study involved 317 consecutive outpatients in Kurume University Hospital (220 male and 97 female) with a mean age of 62.1±9.1. We examined whether serum level of PEDF were independently associated with vascular inflammation evaluated by [(18)F]-fluorodeoxyglucose positron emission tomography (FDG-PET) and intima-media thickness (IMT) in carotid artery in humans. Carotid [(18)F]-FDG uptake, an index of vascular inflammation within the atherosclerotic plaques, was measured as standardized uptake value (SUV). Mean serum PEDF level, carotid SUV and IMT values were 13.5±1.1 μg/mL, 1.34±0.19, and 0.71±0.15 mm, respectively. In multiple stepwise regression analysis, estimated glomerular filtration rate (p<0.001), males (p<0.001), homeostasis model assessment of insulin resistance index (p<0.05), heart rate (p<0.05), triglycerides (p<0.05), carotid IMT (p<0.05), waist circumference (p<0.05) and carotid SUV (p<0.05) were independently correlated to PEDF level (R(2)=0.332). CONCLUSION The present study reveals that serum level of PEDF is independently associated with vascular inflammation and IMT, thus suggesting that PEDF level is a novel biomarker that could reflect atherosclerosis in humans.

Abstract
OBJECTIVES This study evaluated the usefulness of fasting (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) in the diagnosis and management of cardiac sarcoidosis (CS) and compared it with FDG uptake in dilated cardiomyopathy (DCM). BACKGROUND Cardiac sarcoidosis may clinically present as DCM but is amenable to systemic corticosteroid therapy if disease activity is high. Although alterations of FDG uptake have been reported in CS, limited information is available on the quantitative estimates of FDG uptake. METHODS Fasting FDG-PET was performed in 24 systemic sarcoidosis patients and was compared with 8 age-matched DCM patients. FDG-PET was also performed in 15 age-matched healthy control subjects. Twelve of the 24 sarcoidosis patients had cardiac involvement based on criteria established by the Japanese Ministry of Health and Welfare; the remaining 12 of 24 patients revealed no evidence of cardiac involvement. The myocardial FDG uptake was quantified by measuring the standardized uptake value in 17 myocardial segments in each subject. Coefficient of variation (COV), which equals the standard deviation of uptake divided by the average uptake of 17 segments, was calculated as an index of heterogeneity in the heart. RESULTS The FDG uptake was distinctly heterogeneous in CS patients. The COV value was significantly greater in CS patients (0.25 ± 0.05) than control subjects (0.14 ± 0.03, p < 0.01), sarcoidosis patients without cardiac involvement (0.14 ± 0.03, p < 0.01), or DCM patients (0.15 ± 0.02, p < 0.01). The COV value in DCM patients was similar to control subjects or sarcoidosis patients without cardiac involvement. The cutoff COV value for the diagnosis of CS was 0.18 (sensitivity: 100%; specificity: 97%). After corticosteroid therapy in CS patients, the COV value was decreased to 0.14 ± 0.06 (p < 0.05) and became essentially similar to the other groups. CONCLUSIONS Heterogeneous myocardial FDG uptake may be a useful diagnostic marker of disease activity for CS.

Abstract
Percutaneous coronary intervention (PCI) using a drug-eluting stent (DES) leads to less re-stenosis than PCI using a bare metal stent (BMS), however there is still controversy whether use of a DES for severe coronary disease leads to an acceptable outcome in patients with diabetes mellitus (DM). In this study 8159 lesions were treated in 6739 patients (mean age 68.9 years) with coronary artery disease. Use of a DES significantly decreased the re-stenosis rate compared with BMS in both DM (9.6% versus 21.3%) and non-DM (9.5% versus 17.1%) patients. The re-stenosis rate was significantly higher in DM than in non-DM patients in the BMS group but not in the DES group. There was no statistically significant difference in event-free survival after stenting of patients with left main coronary artery (LMCA) disease between the BMS and DES groups. It was concluded that, compared with BMS, DES reduced re-stenosis in patients with DM, however, we advise careful treatment after using DES for severe coronary disease, including LMCA lesions, in patients with DM.

Abstract
Calcium channel blockers (CCBs) can prevent cardiovascular events in patients with coronary artery disease (CAD). This study looked retrospectively at the prognosis of CAD in hypertensive patients with CAD who had undergone a coronary angiograph, had been given a CCB (benidipine [ n = 66], amlodipine [ n = 45], or long-acting nifedipine [ n = 31]) on hospital discharge and were then followed up for a mean ± SD of 5.2 ± 2.9 years. Systolic/diastolic blood pressure for all 142 patients decreased significantly from a mean ± SD of 137 ± 20/74 ± 15 mmHg to 129 ± 20/71 ± 12 mmHg. Major adverse cardiovascular events (MACE) occurred in 15 patients. Chronic kidney disease (CKD) was a significant risk factor for MACE (hazard ratio 2.35, 95% confidence intervals 1.45, 3.80). Benidipine was superior to nifedipine in preventing MACE in patients both with and without CKD. In conclusion, benidipine and amlodipine reduced the frequency of MACE in hypertensive patients with CAD, particularly in those with complicating CKD.

Abstract
OBJECTIVE The high frequency of gastroesophageal reflux disease (GERD) as a complication of scleroderma (systemic sclerosis, SSc) calls for treatment with powerful acid suppressants such as proton pump inhibitors (PPI). The present study used a GERD-specific questionnaire to assess the symptoms of GERD in SSc patients, and examine the effectiveness of rabeprazole (RPZ) for treating the symptoms of GERD. METHODS The Frequency Scale for the Symptoms of GERD (FSSG), a medical questionnaire developed in Japan for evaluating GERD, and the Visual Analogue Scale (VAS) were used to evaluate GERD symptoms and the degree of pain, respectively, in 151 SSc subjects. These tools were also used to assess the effect of 8 weeks' treatment with the PPI RPZ (10 mg/day). RESULTS Data on age and gender, and FSSG and VAS scores before treatment and after 4 and 8 weeks' RPZ treatment, were available for 84 subjects. The mean FSSG score was 13.9+/-9.7 before treatment, 8.3+/-8.1 after 4 weeks of treatment, and 7.0+/-7.0 after 8 weeks of treatment; the score reduction was significant (p<0.001) indicating the effectiveness of RPZ in improving subjective GERD symptoms. The VAS scores revealed a significant improvement in pain after both 4 and 8 weeks compared with baseline scores. Six subjects experienced adverse effects and five discontinued the analysis during the period. CONCLUSION Administration of RPZ 10 mg/day is effective for the control of the symptoms of GERD associated with SSc. In addition to assessing the symptoms of GERD, the FSSG questionnaire can be used to evaluate the therapeutic effect of drugs.

Abstract
The binding of manganese(III)-tetra(4-N-methylpyridyl)porphyrin (MnTMpyP) with synthetic poly(dA-dT)2, poly(dI-dC)2, and poly(dG-dC)2 DNAs as well as calf thymus (CT) DNA has been quantitatively studied in detail using induced CD (circular dichroism) spectroscopy in the Soret absorption band. The CD spectra, which changed greatly depending on the porphyrin to DNA base-pair molar ratio (r), were normalized with respect to DNA concentration and deconvoluted. Three independent component binding modes (named mode 1, 2, and 3 in the order of increasing r values) were identified, which successfully simulated the observed CD spectra with negligibly small residuals for a wide range of r values. In the case of poly(dA-dT)2, poly (dI-dC)2, and CT DNA, all the three modes appeared, whereas in the case of poly(dG-dC)2 DNA, only modes 1 and 3 appeared in the r range studied. The r dependence of each binding mode, i.e., its relative affinity toward DNA, has been revealed by this analysis. Mode 1, which appeared as a single binding mode at very low r values (r < or = ca. 0.05), was inhibited by the addition of methyl green, a drug that preferentially binds to the major groove of poly (dA-dT)2 DNA. Berenil, a known minor groove binder to poly(dA-dT)2 or poly(dI-dC)2 DNA, inhibited modes 2 and 3. From these inhibition experiments as well as comparison of the component spectra for DNAs of different sequence, a binding site on DNA was proposed for each component binding mode. The number of DNA base pairs covered by a single molecule of porphyrin was estimated.

Abstract
We report the first case of primary extragonadal seminoma arising in the perineum. A 34-year-old-man presented with a 2-cm painless mass in the perineum. He underwent surgical resection, and histology showed poorly differentiated adenocarcinoma. Three months later, local recurrence occurred. Whole evaluation including ultrasound and MRI of the testes were normal, so he underwent surgical wide excision, and pathology showed the tumor was pure seminoma. He received two courses of bleomycin, etoposide and cisplatin (BEP) therapy, and there has been no evidence of recurrence for 1 month.

Abstract
Interaction of tamarind seed xyloglucan (TSX) and epigallocatechin gallate (EGCG) was investigated. TSX alone showed the rheological behaviors of dilute and semidilute solution types in the temperature range from 10 to 50 degrees C and the concentration range from 1 to 10%. Addition of a small amount of EGCG changed the rheological properties of TSX solutions to induce a thermoreversible gelation. The sol-gel transition was detected as a crossover of the storage and loss shear moduli at a certain temperature in thermal scanning rheological measurements and an endo- and exo- thermic peaks in curves obtained by differential scanning calorimetry on heating and cooling. High storage modulus of the gels at all experimental frequencies also indicated the formation of a network structure. Increase in the gel strength and the enthalpy of the transition with increasing EGCG concentration at fixed TSX concentration suggested that EGCG was directly involved in the network formation through association with TSX. The TSX gel was obtained by addition of appropriate amount of EGCG. Addition of an excessive amount of EGCG induced precipitation.

Abstract
AIMS To investigate the chronic effects of air pollution caused mainly by automobiles in healthy adult females. METHODS Respiratory symptoms were investigated in 5682 adult females who had lived in the Tokyo metropolitan area for three years or more in 1987; 733 of them were subjected to pulmonary function tests over eight years from 1987 to 1994. The subjects were divided into three groups by the level of air pollution they were exposed to during the study period. The concentrations of nitrogen dioxide and suspended particulate matter were the highest in group 1, and the lowest in group 3. RESULTS The prevalence rates of respiratory symptoms in group 1 were higher than those in groups 2 and 3, except for wheezing. Multiple logistic regression analysis showed significant differences in persistent phlegm and breathlessness. The subjects selected for the analysis of pulmonary function were 94, 210, and 102 females in groups 1, 2, and 3, respectively. The annual mean change of FEV(1) in group 1 was the largest (-0.020 l/y), followed by that in group 2 (-0.015 l/y), and that in group 3 (-0.009 l/y). Testing for trends showed a significant larger decrease of FEV(1) with the increase in the level of air pollution. CONCLUSIONS The subjects living in areas with high levels of air pollution showed higher prevalence rates of respiratory symptoms and a larger decrease of FEV(1) compared with those living in areas with low levels of air pollution. Since the traffic density is larger in areas with high air pollution, the differences among the groups may reflect the effect of air pollution attributable to particulate matter found in automobile exhaust.

Abstract
PURPOSE To investigate the biological effectiveness of neutrons at the energy below 1 MeV on apoptosis and carcinogenesis in the mouse ovary. MATERIALS AND METHODS Female mice were exposed to 1.0 Gy monoenergetic neutrons (0.317, 0.525 and 1.026 MeV), (252)Cf fission neutron (2.13 MeV) or (137)Cs gamma-rays at 7 days of age. Apoptosis of the oocyte and pregranulosa cells, and ovarian carcinogenesis were compared between the radiations. The efficiency of gamma-rays for granulosa cell tumorigenesis was tested by transplantation of the irradiated ovaries into non-irradiated mice. RESULTS The cumulative apoptotic index of oocytes was 77.9%, 65.6% and 41.6% for the 0.525 MeV neutron, 2.13 MeV neutron and gamma-rays, respectively. Follicles with apoptotic pregranulosa cells were 53.0%, 18.3% and 22.8% of cumulative index for the three groups. Tubular adenomas developed in the groups of monoenergetic neutrons (26.1%) and gamma-ray (35.5%), whereas granulosa cell tumours developed only in the gamma-ray groups (3.2% for 1.0 Gy and 15.6% for 3.0 Gy). Partial-body irradiation with 3 Gy gamma-rays to the ovaries induced granulosa cell tumours with an incidence of 27.3%. CONCLUSION Effectiveness of neutrons to cause apoptosis was higher for 0.525 MeV than for 2.13 MeV. The pregranulosa cell apoptosis occurred in an oocyte-prone manner. The higher effectiveness of neutrons than gamma-rays to induce oocyte and pregranulosa cell apoptosis correlates with the inhibition of granulosa cell tumour development.

Abstract
Pancreatic tissue grafting is by far the most physiological therapeutic solution to the insulin deficiency of diabetes. Recent clinical trials have indicated somewhat successful use of nonsteroidal immunosuppressive regimens and a successful nonhuman primate trial using CD154 for costimulation blockade was reported. However, these protocols need to be replaced with safe and efficacious ones in which long-term allotolerance would make these treatments routine in a clinical setting. With the specific objective of testing whether peripheral infusions of stem cells or stem cell fractions in conjunction with islet allografting would induce allograft tolerance, we have established a macaque diabetic model. The macaques were rendered diabetic by streptozotocin and required daily doses of insulin to maintain lower blood glucose levels. The diabetic macaques then received islets and stem cells from unrelated and MHC-mismatched donors without any immunosuppression. In our initial analysis, 5 of 7 macaques that received stem cell infusions at the time of islet allografting have shown allograft survival longer than the group of macaques that received islets without the stem cell infusion. One of these five macaques has been normoglycemic for 10 months, with no exogenous insulin. This macaque received stem cell population enriched for CD34+ cells with depletion of CD18 cells, which have shown low or no allostimulatory potential in mixed lymphocyte cultures. Increased levels in insulin and C-peptide levels were shown in the macaques after islet transplantation.

Abstract
Recent clinical trials have pioneered the successful use of a nonsteroidal immunosuppressive regimen and established a basis for application in a routine clinical setting. In this study, a single islet transplant was not sufficient to regulate blood glucose levels, and a second transplant became necessary. A similar observation was made in our macaque islet transplant study, where animals after the second transplantation have shown trends towards normoglycemia in the presence of mycophenolate mofetil. All five animals that received the second transplant have shown an initial rise in C peptide levels, which rapidly decreased as we tapered the MMF dose from 20 mg/kg BID to 5 mg/kg SID. Two animals of the five that were preconditioned with MMF one week prior to transplantation have shown significantly higher C peptide levels. We believe that it is very important to understand the relationship between the first graft failure and subsequent islet allograft success. Since graft success did not correlate with number of transplanted islets, the correction of blood glucose levels toward normoglycemia after the second transplantation suggests a mechanism by which the allotolerance to second transplant is facilitated by the first islet transplantation. These initial observations suggest approaches to "tolerize" the recipient to accept the second-transplant islets (a) through preconditioning the animal to improve the rate of success for the first transplant or (b) through tolerization to islets in the first transplant to facilitate better engraftment of the second-transplant islets.

Abstract
Severe nausea and vomiting are common side effects of anti-cancer chemotherapy. 5-HT3 receptor antagonists have been used for the treatment of these gastrointestinal symptoms. The purpose of this study was to examine whether specific changes in serotonin dynamics occurred in the gastrointestinal tract in mice in which Colon-26 adenocarcinoma cells were injected s.c., especially after treatment with cisplatin. The serotonin content of the small intestine of mice inoculated s.c. with Colon-26 adenocarcinoma increased significantly 2 weeks after the inoculation of the tumor cells; this was associated with an increase in tryptophan hydroxylase activity and the number of enterochromaffin cells as compared with control mice. Intravenous injection of cisplatin significantly reduced the serotonin content in the small intestine of Colon-26 tumour-bearing mice but not in control mice. The spontaneous release of serotonin from isolated intestine was not different between Colon-26 tumour-bearing and control mice; however, pretreatment of mice with cisplatin induced two fold increases in serotonin release from duodenum, jejunum and ileum in Colon-26 tumour-bearing mice but not in control mice. These results indicate that a region-specific increase in the number of enterochromaffin cells is observed in the intestine of Colon-26 tumour-bearing mice, associated with an increase in the serotonin content and tryptophan hydroxylase activity. Cisplatin treatment induced the release of serotonin from affected enterochromaffin cells in the gastrointestinal tract, which may be related to the occurrence of nausea in clinical use.

Abstract
Extensive atrophy has been reported to occur in the thymus in a cancer-burden state but the mechanisms of this atrophy have not been fully elucidated. We investigated changes in the thymus in tumour-bearing mice inoculated with two subclones of the murine colon 26 adenocarcinoma cell line: clone 5 (non-cachectic) and clone 20 (cachectic). In clone 20 mice, body weights and thymocyte numbers decreased significantly compared with controls. Flow cytometric analysis of the thymocytes demonstrated that the frequency of single positive cells (CD4+ CD8- and CD4- CD8+) was significantly increased and that of double positive cells (CD4+ CD8+) was significantly decreased in clone 20 mice and, to a lesser extent, in clone 5 mice compared with controls. Serum levels of interleukin 6 and granulocyte-macrophage colony-stimulating factor (GM-CSF) were significantly elevated. These results suggested that thymocyte apoptosis was accelerated in the cancer-cachectic state, and increased GM-CSF might be partly responsible for thymic atrophy.

Abstract
We evaluated the effect of intravenous thermosensitive liposomal doxorubicin (TL-DOX) together with local hyperthermia on primary tumors in highly metastatic hamster osteosarcoma. This combination resulted in higher DOX concentrations in plasma, primary tumors and lungs than standard DOX under the same conditions. Tumor growth and lung metastasis were also inhibited more by TL-DOX and hyperthermia than by hyperthermia alone, DOX with or without hyperthermia, and TL-DOX without hyperthermia. In addition, gains in hamster body weight were not suppressed. These results suggest that the combination of TL-DOX and hyperthermia can control primary tumors and suppress lung metastasis in hamsters.

Abstract
In murine leishmaniasis, the induction of the T-helper type 1 (Th1) response contributes to infection resistance, whereas the establishment of the Th2 response makes the mice susceptible to infection. Interleukin-12 (IL-12) plays a pivotal role in the diversification of immune responses to the Th1 type. In this study, we tested whether the co-administration of IL-12 expression plasmid which compose p35 and p40 subunits and soluble leishmanial antigen (SLA) will skew the susceptible BALB/c mice to Th1 response and protect from leishmaniasis. When the mice were intradermally injected with the combination of IL-12 plasmid and SLA 7 days prior to the challenge with 1x10(6) promastigotes of Leishmania major, the local lesions completely healed and the parasite burden in the local lymph nodes significantly decreased. The cured mice attained long-term immunity, and were resistant to any subsequent rechallenge of the lethal dose of the parasite. The protective effect was associated with the development of a Th1 response, as demonstrated by the enhanced level of antigen-specific interferon-gamma (IFN-gamma) and dominant production of IgG2a in the serum. In contrast, the administration of empty plasmid plus SLA or IL-12 plasmid alone failed to protect the disease and shape the Th1 response. Furthermore, the protective efficiency induced by the vaccination was clearly prevented by the injection of either neutralizing anti-IL-12 mAb or anti-IFN-gamma mAb. The IL-12 expression plasmid is thus an effective adjuvant for the elicitation of a protective Th1 response against leishmaniasis and is therefore, considered to be appropriate for vaccinations that require the induction of Th1 type immunity.

Abstract
BACKGROUND During cardiac ischemia-reperfusion injury, neutrophilic infiltration of the myocardium is mediated by adhesion molecule expression on activated coronary endothelium. Nitric oxide inhibits neutrophil adhesion to endothelium in vitro by blocking the nuclear factor (NF)-kappaB-dependent transcription of adhesion molecules. We investigated whether intraoperative gene delivery of endothelial nitric oxide synthase (eNOS) into donor hearts before transplantation would have a similar effect on an entire organ. METHODS AND RESULTS In an allogeneic rabbit heart transplant model, liposomes complexed to the gene encoding eNOS were infused into the donor coronary circulation before transplantation. By 24 hours after transplantation, calcium-dependent nitrite production was significantly higher in eNOS-transfected donor hearts than in the 3 control groups: donor hearts transfected with empty plasmids alone, donor hearts treated with diluent only, and untransplanted native hearts. Intramyocardial neutrophil and T-lymphocyte populations were halved in eNOS-transfected hearts compared with control donor hearts (P<0.05). Moreover, the prevalence of NF-kappaB activation in microvascular endothelial cells and surrounding cardiac myocytes as well as endothelial vascular cell adhesion molecule-1 and intracellular adhesion molecule-1 expression were all significantly reduced in eNOS-transfected hearts compared with control donor hearts (P<0.01). Without immunosuppression, eNOS-transfected hearts survived longer than controls. CONCLUSIONS Intraoperative liposome-mediated gene delivery of eNOS to donor hearts can result in early gene expression sufficient to reduce ischemia-reperfusion injury by inhibiting NF-kappaB activation, adhesion molecule expression, and the early infiltration of leukocytes, all of which may improve graft survival.

Abstract
Female rats of the Fischer 344 strain at ages of 1, 4 and 9 weeks were exposed to 131I intraperitoneally with activities of 0.38, 1.03 and 3.42 kBq per gram of body weight under the condition of iodine deficiency. The absorbed doses in the thyroid increased linearly depending on the injected activities. Irradiation at 1 week old caused heavier exposure than those at 4 and 9 weeks old by 7.5 and 7.7 times, respectively; however, damage of the thyroid tissue was more obvious in the 4-week-old groups than in the 1-week-old groups. The absorbed doses in the total body were proportional to the square root of the injected activities. The one-week-old groups were exposed more heavily than the 4- and 9-week-old groups by 3.6 and 4.7 times, respectively, shown by the slow excretion of 131I with the values of effective half-life of 131I activity (Teff). An IDD-treatment was not so effective to enhance the 131I absorption in the total body, as in the thyroid. No matter how the iodine concentration in the blood changed, the 1-week-old groups could not react to normalize the level. We drew standard curves, which enabled us to estimate the absorbed doses in the thyroid and the total body in the case of the injected activities of 131I for the newborn, pubertal and adult rats.

Abstract
Insulin-dependent diabetes mellitus in the NOD mouse model is caused by the T cell-mediated autoimmune destruction of pancreatic beta cells. Viral IL-10 (vIL-10), encoded in the Epstein-Barr virus genome, shares many of the anti-inflammatory properties of cellular IL-10, but lacks its immunostimulatory properties. In the present study, we generated transgenic (Tg) NOD mice in which vIL-10 was produced exclusively in pancreatic islets and investigated the effect of vIL-10 on the development of diabetes. The accumulation of lymphocytes around islets was more prominent, but the invasive insulitis decreased in the vIL-10 Tg mice. The incidence of diabetes was markedly reduced in the vIL-10 Tg mice, in clear contrast to the accelerated diabetes seen in the murine IL-10 Tg NOD mice. IL-12p40 and IFN-gamma mRNA levels were decreased in pancreata of the vIL-10 Tg mice, although CD4 mRNA level was markedly increased. These results suggest that locally produced vIL-10 induced leukocyte migration, but inhibited the activation of T(h)1, probably through suppressing the production of IL-12. They indicate that vIL-10 may well be superior to cellular IL-10 in the treatment of autoimmune diabetes. The vIL-10 Tg NOD mice should provide a useful tool for understanding the differential action of vIL-10 versus cellular IL-10.

Abstract
The sequences of the genomes in the TO-336 vaccine strain (TO-336vac) of rubella virus and its wild progenitor virus (TO-336wt) have been determined and compared with each other. There were 21 differences in the nucleotide sequences between the TO-336vac and the TO-336wt: 13 in the nonstructural protein open reading frame (NSP-ORF), five in the structural protein open reading frame (SP-ORF) and three in the untranslated regions (UTRs) (one in each three UTRs). These mutations resulted in amino acid substitutions at ten residues. Of the ten substitutions, eight were in NSP-ORF and two were in the SP-ORF. Of the eight substitutions in NSP-ORF, four (amino acids (aa) 320, 501, 573 and 704) were in the regions of unknown function, two (aa 1154 and 1159) were within the protease motif, and two (aa 1351 and 1559) were within the helicase motif. Both of the two residues (aa 890 and 954) in the SP-ORF were within the E1 gene. The predicted second structure of the 5'UTR of the TO-336vac was identical to that of TO-336wt. Comparing the TO-336 sequences with other four strains, Therien and M33 (wild viruses), and RA27/3 and Cendehill (vaccine viruses), the mutations responsible for attenuation are thought to differ with each vaccine strain. This is the first report of sequencing in a pair of live attenuated rubella vaccines and their wild-type parent.
