Abstract
Abstract
Background
Smoking predisposes individuals to endothelial dysfunction. Both flow-mediated dilation (FMD) and reactive hyperemia peripheral artery tonometry (RH-PAT) are used to assess endothelial function. However, there are differences in the physiology of vascular beds being tested and in the response of conduit and resistive vessels to RH. Therefore, whether smoking cessation demonstrates comparable effects on endothelial function evaluated by FMD and by RH-PAT remains unclear.
Purpose
We aimed to evaluate the effects of smoking cessation on endothelial function evaluated simultaneously by FMD and RH-PAT.
Methods
Thirty-eight consecutive current smokers (mean±standard deviation; age, 65±10 years) who visited our smoking cessation outpatient department and succeeded in smoking cessation with varenicline were enrolled. Clinical variables, FMD, and natural logarithmic transformation of the reactive hyperemia index (Ln-RHI) were examined before and 20 weeks after treatment initiation. Fifteen current smokers who failed in smoking cessation were enrolled as age- and sex-matched controls. The Spearman's rank correlation coefficient and intraclass correlation coefficient (ICC) for a two-way mixed effects model were performed to assess the agreement of changes in FMD and Ln-RHI. Multivariate logistic regression analysis was performed to examine the associations between the presence of increase in FMD or Ln-RHI and clinical variables.
Results
FMD significantly improved after smoking cessation (3.42%±1.96% to 4.45%±2.28%; p=0.019), whereas Ln-RHI did not (0.53±0.25 to 0.59±0.21; p=0.223). The Spearman's rank correlation coefficient between changes in FMD and Ln-RHI was −0.013, and the ICC was −0.002 (p=0.506). In the multivariate logistic regression analysis, an increase in FMD or Ln-RHI was predicted based on the baseline FMD (odds ratio = 0.54, p=0.013) or Ln-RHI (odds ratio = 0.36, p=0.012), respectively, after adjusting for age and sex.
Conclusions
There was significant improvement in the endothelial function assessed by FMD, but not by Ln-RHI, after smoking cessation. In addition, there was disagreement between changes in FMD and those in Ln-RHI. Smoking cessation may have varying effects on the endothelial function of the conduit and digital vessels.

Abstract
Abstract
Background
Omega-3 polyunsaturated fatty acids (n-3 PUFAs) are well-known for preventing cardiovascular disease. Among n-3 PUFAs, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play key roles in preventing cardiovascular diseases. However, the effects of n-3 PUFAs have been examined under conditions of simultaneous administration of EPA and DHA in the majority of clinical investigations and the effect of purified EPA is still controversial. EPA has been reported to improve endothelial dysfunction. Although several mechanisms underlying the effects of EPA on endothelial function have been demonstrated such as the modulation of lipid metabolism including increases in high-density lipoprotein (HDL) and/or decreases in triglyceride (TG) levels, decreases in cytokine production, and inhibition of inflammatory processes, the main mechanisms ameliorating endothelial function have not been fully determined.
Purpose
We sought to clarify the main factors associated with EPA administration that led to improved endothelial function.
Methods
Fifty-one consecutive patients with hypertriglyceridemia (mean ± SD age, 60±13 years) with no evidence of coronary artery disease (CAD) were prospectively enrolled and administered purified EPA (1800 mg/day). Forty-eight patients who were not administered EPA were enrolled as age- and sex-matched controls. Clinical variables such as body mass index, HbA1c, fasting glucose level, HDL, low-density lipoprotein, TG, systolic blood pressure, diastolic blood pressure, heart rate, interleukin-6, baseline diameter of the brachial artery, intima-media thickness of the brachial artery, and flow-mediated dilation (FMD) were examined before and after 6 months of treatment. Univariate and multivariate regression analyses were performed to examine the associations between FMD changes and clinical variables.
Results
FMD was significantly improved from 4.16% ± 1.88% to 6.30% ± 2.24% (p<0.0001) in the EPA group. The change in FMD was positively correlated with the change in EPA/arachidonic acid (AA) ratio (r=0.34, p=0.014). The multivariate regression analysis showed that the change in EPA/AA ratio alone was significantly associated with the change in FMD (p=0.010).
Conclusions
EPA treatment improves endothelial dysfunction in patients with hypertriglyceridemia without evidence of CAD. The change in FMD was associated with the change in EPA/AA ratio alone. These finding suggest that a direct effect of EPA on the endothelium may be the predominant factor ameliorating endothelial function.

The Role of PD-1 Positivity in the Tumour Nest on Clinical Outcome in Upper Tract Urothelial Carcinoma Patients Treated with Radical Nephroureterectomy. Clin Oncol (R Coll Radiol) 2017; 30:e1-e8. [PMID: 29153625 DOI: 10.1016/j.clon.2017.10.019] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2017] [Revised: 09/26/2017] [Accepted: 10/12/2017] [Indexed: 11/15/2022]
Abstract
AIMS The role of PD-1 (programmed cell death 1) expression on the clinical outcome of upper tract urothelial carcinoma has not yet been elucidated in detail. MATERIALS AND METHODS PD-1 expression was immunohistochemically examined in 181 upper tract urothelial carcinoma patients who underwent radical nephroureterectomy. A part of PD-1 protein expression in the tumour periphery and tumour nest was evaluated separately. The PD-1-positive cells were counted in the area showing the highest density of PD-1 expression at a magnification of 400×. RESULTS PD-1 staining in the tumour nest was low in 137 (75.7%) and high in 44 (24.3%) patients. PD-1 staining in the tumour periphery was low in 78 (43.1%) and high in 103 (56.9%) patients. The 5 year progression-free survival rates in patients with the high PD-1 expression in the tumour nest and in the tumour periphery were 54.6% and 67.7%, respectively, which were significantly lower than those in their counterparts (79.4%, P < 0.001; 80.0%, P = 0.04). The 5 year cancer-specific survival rates in patients with the high PD-1 expression in the tumour nest and the tumour periphery were 69.1% and 75.7%, respectively, which were significantly lower than those in their counterparts (84.7%, P = 0.007; 87.8%, P = 0.01). A multivariate Cox regression analysis identified the high PD-1 expression in the tumour nest (hazard ratio 3.07, P < 0.001; hazard ratio 2.44, P = 0.011) and positive lymphovascular invasion (hazard ratio 4.86, P < 0.001; hazard ratio 4.03, P < 0.001) as independent predictors of disease progression and of cancer death, respectively. CONCLUSIONS PD-1 positivity in the tumour nest could be a strong predictor for a worse clinical outcome and may be a useful indicator for selecting appropriate candidates for adjuvant therapy such as chemotherapy in upper tract urothelial carcinoma patients treated with radical nephroureterectomy.

Abstract
BACKGROUND AND PURPOSE Vasopressin V1B receptor antagonists may be effective for the treatment of depression and anxiety and the objective of this study was to characterize the pharmacological profiles of two newly synthesized arginine vasopressin receptor 1B (V1B receptor) antagonists, TASP0233278 and TASP0390325. EXPERIMENTAL APPROACH We investigated the in vitro profiles of TASP0233278 and TASP0390325. In addition, the effect of TASP0390325 on the increase in plasma adrenocorticotropic hormone (ACTH) levels induced by corticotropin-releasing factor (CRF)/desmopressin (dDAVP) was investigated. We also investigated the antidepressant and anxiolytic profiles of TASP0233278 and TASP0390325 in animal models. KEY RESULTS Both TASP0233278 and TASP0390325 showed a high affinity and potent antagonist activity for V1B receptors. Oral administration of TASP0390325 antagonized the increase in plasma ACTH levels induced by CRF/dDAVP in rats, indicating that TASP0390325 blocks the anterior pituitary V1B receptor in vivo. Oral administration of TASP0233278 or TASP0390325 also exerted antidepressant effects in two models of depression (a forced swimming test and an olfactory bulbectomy model). Moreover, TASP0233278 improved depressive-like behaviour induced by repeated treatment with corticosterone, a model that has been shown to be resistant to treatment with currently prescribed antidepressants. In addition to depression models, TASP0233278 or TASP0390325 exerted anxiolytic effects in several anxiety models (social interaction, elevated plus-maze, stress-induced hyperthermia, separation-induced ultrasonic vocalization and sodium lactate-induced panic-like responses in panic-prone rats). CONCLUSION TASP0233278 and TASP0390325 are potent and orally active V1B receptor antagonists with antidepressant and anxiolytic activities in rodents.

Abstract
BACKGROUND Cigarette smoking is the major cause of lung cancer (LC). Although the time to first cigarette (TTFC) of the day is a distinct indicator of nicotine dependence, little information is available on its possible relation to LC. PATIENTS AND METHODS This case-control study includes a total of 1572 incident LC cases and 1572 non-cancer controls visiting for the first time the Aichi Cancer Center Hospital between 2001 and 2005. We estimated the odds ratio (OR) and 95% confidence interval (CI) for TTFC using a logistic regression model after adjustment for several potential confounders. RESULTS TTFC was inversely associated with the risk of LC. This association was consistent across histological subtypes of LC. For all LCs considered among ever smokers and after accurate allowance for smoking quantity and duration, besides other relevant covariates, compared with TTFC >60 min, the adjusted ORs were 1.08 (95% CI, 0.73-1.61) for TTFC of 31-60 min, 1.40 (0.98-2.01) for 6-30 min and 1.86 (1.28-2.71) for within 5 min (Ptrend, < 0.001). Statistically marginally significant heterogeneity by histological subtype was observed (Pheterogeneity, 0.002). CONCLUSIONS Nicotine dependence, as indicated by the TTFC, is associated with increased risk of LC and is therefore an independent marker of exposure to tobacco smoking.

Abstract
A crucial safety measure to be strictly observed in the operation of heavy-water nuclear power plants is the mandatory regular inspection of the concentration of deuterium penetrated into the zircaloy fuel vessels. The existing standard method requires a tedious, destructive, and costly sample preparation process involving the removal of the remaining fuel in the vessel and melting away part of the zircaloy pipe. An alternative method of orthogonal dual-pulse laser-induced breakdown spectrometry (LIBS) is proposed by employing flowing atmospheric helium gas without the use of a sample chamber. The special setup of ps and ns laser systems, operated for the separate ablation of the sample target and the generation of helium gas plasma, respectively, with properly controlled relative timing, has succeeded in producing the desired sharp D I 656.10 nm emission line with effective suppression of the interfering H I 656.28 nm emission by operating the ps ablation laser at very low output energy of 26 mJ and 1 μs ahead of the helium plasma generation. Under this optimal experimental condition, a linear calibration line is attained with practically zero intercept and a 20 μg/g detection limit for D analysis of zircaloy sample while creating a crater only 10 μm in diameter. Therefore, this method promises its potential application for the practical, in situ, and virtually nondestructive quantitative microarea analysis of D, thereby supporting the more-efficient operation and maintenance of heavy-water nuclear power plants. Furthermore, it will also meet the anticipated needs of future nuclear fusion power plants, as well as other important fields of application in the foreseeable future.

METHODS Ninety-eight subjects who had at least one component of MS were randomized into standard intervention (SI) (4-month intervention; n = 50) and extended intervention (EI) (10-month intervention; n = 48) groups, and 39 subjects were followed up for a control group. The effects of intervention were evaluated after 10, 22 and 34 months. RESULTS At month 10, the standard and EI groups showed improved body mass index (BMI) (SI, -0.28; EI, -0.47; control, -0.09), high-density lipoprotein (HDL) cholesterol, fasting plasma glucose and A1c and a decreased mean number of components of MS (SI, -0.37; EI, -0.51; control, 0.08). At month 34, the effects on BMI (SI, -0.66; EI, -0.60; control, -0.05) and HDL-cholesterol were sustained for both the intervention groups. In controls, the increases in fasting plasma glucose and the mean number of components of MS from the baseline to month 34 were greater than those in the standard and EI groups. Whole body insulin sensitivity index and hepatic insulin resistance index were also improved at month 10. CONCLUSIONS Group-based lifestyle intervention could be an efficient way to prevent MS. Its effects were sustainable, at least in part, for 2 years. These effects may be mediated by an improvement in insulin sensitivity.

Inhibition of Bach1 ameliorates indomethacin-induced intestinal injury in mice. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2009; 60 Suppl 7:149-154.

Abstract
BTB and CNC homolog 1 (Bach1) is a transcriptional repressor of heme oxygenase-1 (HO-1). It plays an important role in the feedback regulation of HO-1 expression, which protects cells from various insults including oxidative stress and inflammatory cytokines. However, the role of Bach1 in intestinal inflammation remains unclear. In this study, the role of Bach1 in intestinal mucosal injury was elucidated using 8-week-old female C57BL/6 (wild-type) and homozygous Bach1-deficient C57BL/6 mice. Intestinal mucosal injuries induced by a single subcutaneous administration of indomethacin were evaluated macroscopically, histologically, and biochemically. Mucosal protein content and chemokine mRNA levels were determined by real-time PCR. Our results showed that the indomethacin-induced intestinal injury was remarkably improved in Bach1-deficient mice. Histological examination showed that the area of injured lesion was decreased in Bach1-deficient mice compared to wild-type mice. Administration of indomethacin induced expression of inflammatory chemokines such as KC, MIP1alpha and MCP1, which was suppressed in Bach1-deficient mice. Myeloperoxidase activity in the intestinal mucosa was also significantly decreased in Bach1-deficient mice. Additionally, Bach1 deficiency enhanced immunopositivity of HO-1 in the intestinal mucosa after indomethacin administration. Disruption of the Bach1 gene thus caused inhibition of mucosal injury, indicating that inhibition of Bach1 may be a novel therapeutic strategy for treating indomethacin-induced intestinal injury.

Abstract
Glucocorticoids, the most downstream effectors of the hypothalamus-pituitary-adrenal axis, are one of main mediators of the stress reaction. Indeed, exposure to high levels of stress-triggered glucocorticoids is detrimental to brain development associated with abnormal behaviors in experimental animals and the risk of psychiatric disorders in humans. Despite the wealth of this knowledge, the cellular and molecular mechanisms underlying the detrimental effects of glucocorticoids on brain development remain unclear. Here, we show that excess glucocorticoids retard the radial migration of post-mitotic neurons during the development of the cerebral cortex, and identify an actin regulatory protein, caldesmon, as the glucocorticoids' main target. The upregulation of caldesmon expression is mediated by glucocorticoid receptor-dependent transcription of the CALD1 gene encoding caldesmon. This upregulated caldesmon negatively controls the function of myosin II, leading to changes in cell shape and migration. The depletion of caldesmon in vivo impairs radial migration. The overexpression of caldesmon also causes delayed radial migration during cortical development, mimicking the excessive glucocorticoid-induced retardation of radial migration. We conclude that an appropriate range of caldesmon expression is critical for radial migration, and that its overexpression induced by excess glucocorticoid retards radial migration during cortical development. Thus, this study provides a novel insight into the underlying mechanism of glucocorticoid-related neurodevelopmental disorders.

Abstract
Gene expressions of acclimatized and non-acclimatized diapausing larvae were examined in Chilo suppressalis using a subtraction technique. A gene encoding a methionine-rich storage protein, CsSP1, was cloned and its complete cDNA sequence was determined. Potentially, CsSP1 encoded a 758-amino acid protein, with a calculated molecular weight of 88.8 kDa. The expression level of CsSP1 was higher in nondiapausing larvae than in diapausing ones. The CsSP1 expression was up-regulated in diapausing larvae when the temperature of cold acclimation was shifted to 5 degrees C. The up-regulated level was maintained at 40 days after incubation at 5 degrees C. In nondiapausing larvae, CsSP1 expression was down-regulated when the temperature was below developmental zero. Involvement of CsSP1 in diapause, cold tolerance acquisition and postdiapause development in C. suppressalis is discussed.

Abstract
The dynamics of magnetic domain wall motion in the FeNi layer of a FeNi/Al2O3/Co trilayer has been investigated by a combination of x-ray magnetic circular dichroism, photoelectron emission microscopy, and a stroboscopic pump-probe technique. The nucleation of domains and subsequent expansion by domain wall motion in the FeNi layer during nanosecond-long magnetic field pulses was observed in the viscous regime up to the Walker limit field. We attribute an observed delay of domain expansion to the influence of the domain wall energy that acts against the domain expansion and that plays an important role when domains are small.

Abstract
The efficacy of sparfloxacin (SPFX) for the control of bronchial asthma was evaluated in 26 patients with suspected Chlamydia pneumoniae infection. Patients were randomly allocated to receive SPFX 200 mg/day (n = 14) or control treatment (n = 12) for 21 days. Significant improvements in serum C-reactive protein levels, and significant decreases in peripheral eosinophil counts, serum eosinophil cationic protein (ECP) and sputum ECP were observed in the SPFX-treated group at day 21. SPFX-treated patients also had a significantly reduced frequency of asthma symptoms, reduced inhalant beta2-stimulant use, and significant increases in morning peak expiratory flow. At the end of the study, C. pneumoniae was undetectable in two SPFX-treated patients who underwent polymerase chain reaction testing, but one control patient who was tested still had detectable levels of C. pneumoniae. These results suggest that SPFX could be used to control bronchial asthma in patients with suspected persistent C. pneumoniae infection.

Abstract
CPT I (outer membrane carnitine palmitoyltransferase I) is a crucial enzyme in myocardial substrate selection. Two isoforms exist in the heart, the liver (L-) and muscle (M-) isoforms, which have different kinetic characteristics and alter in relative amounts during the neonatal/weaning/adult transition. CPT I is a point for control and regulation of fatty acid oxidation via modulation of its activity by malonyl-CoA, the concentration of which is set by acetyl-CoA carboxylase, AMP-activated protein kinase and malonyl-CoA decarboxylase in response to, for example, alterations in glucose supply. Systemic inflammatory responses and sepsis lead to myocardial dysfunction as part of multiple system organ failure. We have shown that: (i) myocardial CPT I activity is inhibited during neonatal sepsis; (ii) on the basis of inhibitor studies this inhibition appears to be of M-CPT I rather than L-CPT I; (iii) nitration of M-CPT I occurs, probably by peroxynitrite, and this may be responsible for the decrease in CPT I activity; (iv) myocardial CPT I activity is also inhibited in another model of systemic inflammatory response, namely intestinal ischaemia/reperfusion injury, but this can prevented by whole-body moderate hypothermia. Inhibition of M-CPT I would be predicted to alter myocardial substrate selection but there are several questions that remain to be answered.

Abstract
OBJECTIVE Buffered and enteric-coated formulations of low-dose aspirin therapy are although expected to avoid gastrointestinal complications, there are reports that these modified products are associated with such complications. One available option for preventing aspirin-induced gastrointestinal complications is the simultaneous use of the agents that inhibit acid secretion such as H(2)-receptor antagonists and proton pump inhibitors. We compared the frequency of prescriptions for antisecretory drugs between users of either buffered or enteric-coated low-dose aspirin. METHODS Monthly prescriptions at the National Cardiovascular Center for aspirin products and antisecretory drugs were counted from January 1998 to December 2002. Counting was based on information from a prescription database file compiled from a computerized order entry system. Time-series analyses were performed to determine changes in the frequency of prescriptions for low-dose aspirin products and antisecretory drugs. In addition, the frequency of prescriptions for antisecretory drugs was compared in individuals using either buffered or enteric-coated low-dose aspirin. RESULTS A significant reduction in the frequency of prescriptions for H(2)-receptor antagonists was observed during 2001 in users of enteric-coated low-dose aspirin compared with users of buffered low-dose aspirin users. In contrast, we observed a significant increase in the frequency of prescriptions for H(2)-receptor antagonists in users of enteric-coated low-dose aspirin during 2002. This change in prescribing H(2)-receptor antagonists in users of enteric-coated low-dose aspirin began in the latter half of 2001. Proton pump inhibitors accounted for 0.31% of prescriptions in users of buffered low-dose aspirin and 0.47% in users of enteric-coated low-dose aspirin, with this difference being statistically significant. CONCLUSION The findings of the present study do not support the notion that enteric-coated low-dose aspirin reduces the risk of gastrointestinal complications and is safer than buffered low-dose aspirin products. However the usual caution about making inferences from observational retrospective data is appropriate.
