Abstract
BACKGROUND Celiac axis stenosis (CAS) is frequently observed in patients undergoing pancreaticoduodenectomy (PD). This poses challenges because of the potential disruption of the hepatic arterial blood flow. CASE PRESENTATION We present the case of an 81-year-old woman diagnosed with pancreatic head cancer and severe CAS caused by calcification. The patient received neoadjuvant chemotherapy (NAC) and underwent preoperative endovascular stenting of the celiac axis to restore blood flow. After two cycles of NAC, subtotal stomach-preserving PD was performed. An intraoperative assessment of the hepatic arterial blood flow determined that it was well maintained. PD was performed using the standard technique; specialized techniques were not necessary. Importantly, no ischemic complications were encountered. CONCLUSION This case report describes the successful combination of preoperative celiac axis stenting, NAC, and surgical intervention for the management of CAS in an elderly patient with pancreatic cancer. This approach offers a potential solution for maintaining the hepatic arterial blood flow in the presence of CAS without vascular reconstruction, particularly in elderly individuals.

Abstract
A 78-year-old man underwent a tracheostomy after embolization for a dural arteriovenous fistula. Seventy days after tracheostomy, arterial bleeding appeared through the tracheal stoma. The bleeding stopped spontaneously. However, two days later, arterial bleeding reappeared, and he was diagnosed with a tracheo-innominate artery fistula (TIF). He then underwent urgent endovascular covered stent placement. After the procedure, there was no bleeding. TIF can be a fatal complication after tracheostomy and it is generally treated with open chest surgery. However, a successful endovascular treatment for TIF has recently been reported and may yield better results.

Abstract
Abstract
Background
Home-based exercise after endovascular treatment (EVT) for lower extremity peripheral artery disease (LE-PAD) patients with intermittent claudication is suggested as an alternative therapy for supervised exercise; however, an association of adherence to home-based exercise with clinical adverse events has not been fully investigated.
Purpose
We aimed to investigate the association of adherence to home-based exercise with 1-year major adverse events (MAE), patency, and leg symptoms after EVT in a contemporary Japanese registry.
Methods
A total of 500 patients with LE-PAD within the Long Term Outcome of Endovascular Therapy for PAD with Intermittent Claudication Observational Prospective Multicenter (ASHIMORI-IC) registry (UMINCTR, UMINehab724.203718753) who underwent EVT between January 2016 and March 2019 were included in the analysis. After EVT, all patients were instructed to do home-based walking exercise with a pedometer. The study population was divided and compared between 2 groups according to adherence to home-based exercise: well-adherence and poor-adherence. The adherence of home-based exercise was as defined by step count derived from a pedometer on sites. The primary outcome was MAE defined as composite of all-cause death, myocardial infarction, stroke, target vessel revascularization, and major amputation of target lower limb for one year. The main secondary outcome was 1-year primary patency of the treated lesion, and the improvement of leg symptom (6-minute walk distance [6MWD] and claudication distance). The study followed the Consensus definitions from peripheral academic research consortium criteria.
Results
Overall, the mean age was 72.8 years, and 78% were men. At 1 year, MAE occurred in 45 patients (9.0%), and the primary patency rate was 85.3% (94.2% of EVT for aortoiliac and 71.9% of EVT for femoropopliteal). A significant difference in the incidence of MAE was observed between the well-adherence group and the poor-adherence group (10 of 233 patients [4.3%] vs. 35 of 267 patients [13.1%]; P<0.001). After multivariate Cox regression analysis, patients in the well-adherence group showed the lower hazard ratio for 1-year MAE (0.30; 95% confidence interval, 0.15–0.58; P<0.001) compared to those in the poor-adherence group. In the well-adherence group, compared with the poor-adherence group, higher primary patency rate (88.9% vs 81.5%; p=0.015), longer claudication onset distance (370 m [IQR 240–453 m] vs 240m [IQR 126–324 m]; P<0.001), and longer 6MWD (422 m [IQR 359–483 m] vs 325 m [IQR 213–400 m]; P<0.001) were observed even after adjusting for each baseline value.
Conclusion
Our study demonstrates the importance of adherence to home-based walking exercise after EVT in LE-PAD patients.

Abstract
Aims Fibrosis‐4 index (FIB‐4 index), calculated by age, aspartate aminotransferase, alanine aminotransferase, and platelet count, is a simple marker to evaluate liver fibrosis and is associated with right‐sided heart failure. However, the clinical relevance of FIB‐4 in patients with heart failure with preserved ejection fraction (HFpEF) remains unclear. We investigated the prognostic implication of the FIB‐4 index regarding right ventricular dysfunction in patients with HFpEF. Methods and results This prospective study included 116 consecutive HFpEF patients (mean age 79 years, 43% male) hospitalized with acute decompensated heart failure. We evaluated the association of the FIB‐4 index with right ventricular function determined by tricuspid annular plane systolic excursion (TAPSE) and tricuspid lateral annular systolic velocity (S′) before discharge. Cox regression analysis was performed to evaluate the association between the FIB‐4 index and major adverse cardiovascular events (MACE) defined as the composite of cardiovascular death, readmission for heart failure, nonfatal myocardial infarction, and nonfatal stroke. FIB‐4 index before discharge was significantly lower than that at admission (2.62 [1.92–3.46] and 3.03 [2.05–4.67], median [interquartile range], P < 0.001). Left ventricular ejection fraction, TAPSE, and S′ before discharge were 62.7 (55.9–68.6) %, 17.5 ± 4.6 mm (mean ± standard deviation), and 10.0 (8.0–12.0) cm/s, respectively. In multiple linear regression analysis, the FIB‐4 index before discharge was inversely correlated with TAPSE (β minus;0.244, P = 0.014) and S′ (β −0.266, P = 0.009). During a median follow‐up of 736 days, 37 MACE occurred. Multivariate Cox regression analysis revealed that a high FIB‐4 index before discharge (per 1 point) was a significant predictor of MACE (hazard ratio 1.270, 95% confidence interval 1.052–1.532) after adjustment for male, serum creatinine, and haemoglobin. Receiver operating characteristic analysis indicated that the optimal cut‐off value of FIB‐4 index before discharge to predict MACE was 3.11. Kaplan–Meier survival analysis showed that patients with a FIB‐4 index before discharge ≥3.11 had a significantly poorer prognosis than patients with FIB‐4 index before discharge <3.11 (P = 0.029). Patients with an FIB‐4 index ≥3.11 had a 2.202‐fold (95% confidence interval 1.110–4.368) increased risk of MACE compared with those with an FIB‐4 index <3.11 after adjustment for male, serum creatinine, and haemoglobin. Conclusions An increase in the FIB‐4 index was associated with right ventricular dysfunction and a higher risk of future MACE in patients with HFpEF.

Abstract
Abstract
A Certified Reference Material (CRM) was prepared at the National Institute for Environmental Studies (NIES), Japan, in collaboration with the National Institute of Radiological Sciences (NIRS), Japan, for the analytical quality assurance of minor and trace elements in food and related matrixes. The starting material for the CRM was all food served in 29 households in Japan over two 3-day periods in 1997–1998, and thus the CRM represented a typical Japanese diet. All foods (meals, snacks, and beverages) were homogenized, freeze-dried, pulverized, blended, dispensed into 1100 bottles, and sterilized. The within- and between-bottle homogeneity of the prepared CRM was satisfactory for most of the elements. The concentrations of 14 elements (Na, Mg, K, Ca, Mn, Cu, Zn, As, Se, Sr, Cd, Sn, Ba, and U) were certified based on a collaborative analysis involving NIES, NIRS, and 20 other laboratories. Reference values were given for the concentrations of 12 additional elements (P, Cl, Fe, Co, Ni, Br, Rb, Mo, I, Cs, Pb, and Th). The elements certified and those given reference values include minerals, essential trace elements, contaminant elements, and long-lived radionuclides. Thus, this CRM is of practical value in the quality assurance of element analysis of foods and diets in nutritional, environmental, and radiological research.

Abstract
ObjectiveAlthough blood pressure (BP) is a major determinant of arterial stiffness, whether high pulse wave velocity (PWV) adversely influences cardiac parameters and cardiovascular (CV) outcome in patients without high BP remains unclear.MethodsOutpatients without high BP (n=320), defined as systolic BP ≥140 mm Hg, were enrolled in this retrospective study. At baseline, all patients underwent echocardiography and multidetector CT to determine the coronary artery calcification (CAC) score. Arterial stiffness was assessed based on brachial-ankle PWV (baPWV), from which patients were classified into two groups: those with high (≥18 m/s, n=89) and low baPWV (<18 m/s, n=231). Cardiac parameters and CV event incidence during the follow-up period were compared between these groups.ResultsIn multivariable linear regression analysis, baPWV was significantly associated with CAC score and serum N-terminal pro-brain natriuretic peptide hormone level, after adjustment for confounding factors. In multivariable logistic regression analysis, baPWV ≥18 m/s was significantly associated with CAC score ≥400 (OR 2.466, 95% CI 1.012 to 6.009, p=0.0471). Kaplan-Meier analysis showed that the high-baPWV group experienced more CV events during the 575 days of follow-up (20% vs 6%, p=0.0003).ConclusionsHigh baPWV was associated with greater CAC and a high risk of a future CV event, especially coronary artery disease, even in patients without high BP.

Abstract
BACKGROUND Ambulatory measurement of intrathoracic impedance (ITI) with an implanted device has potential to assess fluid accumulation in patients with heart failure (HF), but it has failed to reduce HF-related hospitalization because of a high false-positive rate. OBJECTIVE We aimed to examine whether a modified algorithm (OptiVol 2.0) could reduce false-positive HF events documented in our multicenter trial (MOMOTARO). METHODS The MOMOTARO trial assessed the potential that fluid index could predict fluid accumulation and therefore HF. The MOMOTARO trial assessed whether HF events could be detected based on fluid accumulation as assessed by fluid index. We re-analyzed raw data of ITI trends of the threshold-crossing events with the modified algorithm. RESULTS The study consisted of 195 patients who had been implanted with a high-energy device. During a mean follow-up period of 658±165 days, there were 154 primary HF events detected by the previous algorithm (OptiVol 1.0). With the previous algorithm, there was no significant difference in log concentration of brain natriuretic peptide (BNP) between baseline and alert (p=0.21). Among 150 alerts of the previous algorithm, only 37 reached the threshold by the modified algorithm, and log BNP was significantly higher in these 37 events compared with the baseline value (2.40±0.46 vs. 2.27±0.52, p<0.01). CONCLUSION Our simulation study demonstrates that fluid index calculated with the modified algorithm reduces the number of false-positive threshold-crossing HF events and is promising for accurate diagnosis of fluid accumulation in patients.

Abstract
This paper reports the preliminary results of a new in-situ three-dimensional (3D) imaging system for observing plastic deformation behavior in a transmission electron microscope (TEM) as a directly relevant development of the recently reported straining-and-tomography holder [Sato K et al. (2015) Development of a novel straining holder for transmission electron microscopy compatible with single tilt-axis electron tomography. Microsc. 64: 369-375]. We designed an integrated system using the holder and newly developed straining and image-acquisition software and then developed an experimental procedure for in-situ straining and time-resolved electron tomography (ET) data acquisition. The software for image acquisition and 3D visualization was developed based on the commercially available ET software TEMographyTM. We achieved time-resolved 3D visualization of nanometer-scale plastic deformation behavior in a Pb-Sn alloy sample, thus demonstrating the capability of this system for potential applications in materials science.

Abstract
A 76-year-old man taking theophylline was admitted to our hospital with congestive heart failure and supraventricular tachycardia (SVT). After admission, he developed cardiogenic shock as a result of SVT storm, which was refractory to medical treatment including adenosine and electrical cardioversion. The serum theophylline concentration at admission was identified as toxic. Therefore, theophylline toxicity was considered as a major cause of the SVT storm. Hemodynamic stability was achieved by using mechanical circulatory support. Additionally, continuous hemodiafiltration was performed to remove theophylline, and it was effective for suppression of SVT. The patient was successfully weaned off mechanical circulatory support. After the patient's general status had improved, an electrophysiological study was performed, and it showed orthodromic atrioventricular reentrant tachycardia with a right free wall accessory pathway. Radiofrequency catheter ablation was successfully performed. <Learning objective: SVT is often hemodynamically stable and medically well-controllable with adenosine. However, SVT is occasionally refractory or life-threatening under specific conditions such as theophylline toxicity, since theophylline has an inhibitor effect on adenosine. Mechanical circulatory support should be used in case of life-threatening SVT storm associated with theophylline toxicity.>.

Abstract
BACKGROUND Transabdominal preperitoneal (TAPP) repair is the most widely used laparoscopic technique for the treatment of inguinal hernia in Japan. Many studies have shown that in comparison with open hernia repair, laparoscopic repair results in less pain and a shorter convalescence. However, postoperative pain remains a concern. One possible cause of postoperative pain in the early postoperative phase is strain or cough on removal of the endotracheal tube. Use of a supraglottic airway (SGA) device helps to avoid such complaints. We evaluated postoperative pain after TAPP repair using the SGA for general anesthesia. METHODS We evaluated the postoperative pain in 146 patients with inguinal hernia repaired by TAPP in our hospital between May 2013 and May 2016. A total of 144 adult patients of American Society of Anesthesiologists physical status I and II who underwent needlescopic TAPP surgery were randomly allocated to one of two groups of 72 patients: group A (SGA), in which the patient's airway was secured with an appropriately sized I-gel, and group B (endotracheal tube), in which the airway was secured under laryngoscopy. RESULTS There was no significant difference between the groups regarding patient background, postoperative hospital stay, and operation time, and TAPP was performed safely in all cases. In the analysis of postoperative pain, the mean Numerical Rating Scale score of peak pain in group A was significantly less than that of group B (2.10 ± 2.05 vs 2.90 ± 2.65; p = 0.043). In group A, the percentage of patients who had an NRS score of 0 was 51.4% 30 min after surgery, 62.5% after 6 h and 68.1% at POD1, and compared to group B, the NRS scores were significantly higher at POD1 (p = 0.003), and the level of postoperative pain in group A tended to decrease earlier than that in group B. CONCLUSIONS The results of this study are the first to show that an SGA device can reduce postoperative pain after laparoscopic surgery.

Abstract
The assessment of polluted areas and municipal solid waste (MSW) sites using non-destructive geophysical methods is timely and much needed in the field of environmental monitoring and management. The objectives of this study are (i) to evaluate the ground-penetrating radar (GPR) wave responses as a result of different electrical conductivity (EC) in groundwater and (ii) to conduct MSW stratification using a controlled lysimeter and modeling approach. A GPR wave simulation was carried out using GprMax2D software, and the field test was done on two lysimeters that were filled with sand (Lysimeter-1) and MSW (Lysimeter-2). A Pulse EKKO-Pro GPR system with 200- and 500-MHz center frequency antennae was used to collect GPR field data. Amplitudes of GPR-reflected waves (sub-surface reflectors and water table) were studied under different EC levels injected to the water table. Modeling results revealed that the signal strength of the reflected wave decreases with increasing EC levels and the disappearance of the subsurface reflection and wave amplitude reaching zero at higher EC levels (when EC >0.28 S/m). Further, when the EC level was high, the plume thickness did not have a significant effect on the amplitude of the reflected wave. However, it was also found that reflected signal strength decreases with increasing plume thickness at a given EC level. 2D GPR profile images under wet conditions showed stratification of the waste layers and relative thickness, but it was difficult to resolve the waste layers under dry conditions. These results show that the GPR as a non-destructive method with a relatively larger sample volume can be used to identify highly polluted areas with inorganic contaminants in groundwater and waste stratification. The current methods of MSW dumpsite investigation are tedious, destructive, time consuming, costly, and provide only point-scale measurements. However, further research is needed to verify the results under heterogeneous aquifer conditions and complex dumpsite conditions.

Abstract
Four patient (3 males, 1 female) with meningioma treated by preoperative embolization using lipiodol since January 1997 were included in this study. Almost the same procedure was performed on them; superselective catheterization into feeders from the external carotid artery, slow infusion of lipiodol, and proximal occlusion with liquid coils. Duration between embolization and direct surgery varied (5–13 days). Three meningiomas resected 5 days after the embolization were successful but one resected after 13 days needed transfusion. Post operative complications were seen in two patients, one is lockjaw due to ischaemia of the temporal muscles, and the other is transient dilatation of perifocal oedema. The ischaemic effect and safety of lipiodol as embolic material are discussed.

Abstract
Invasive tracheal aspergillosis (ITA) is an infection that is unique to patients who have undergone lung transplantation (LT). Although the activity of this disease often appears on imaging, we encountered a case of ITA that became exacerbated, despite few computed tomography (CT) findings, during rituximab combined chemotherapy for diffuse large B-cell lymphoma. ITA developed during immunosuppressive therapy after LT. Because CT findings may show false-negative results, bronchoscopy is recommended for such cases.

Abstract
BACKGROUND The presence of coronary artery calcification (CAC) and its severity predict future cardiovascular events and is used for risk stratification. However, the association of CAC with heart failure (HF) in patients without a history of coronary artery disease (CAD) remains unclear. This study aimed to determine the correlations of CAC with N-terminal pro-B-type natriuretic peptide (NT-proBNP) and HF events in patients without a history of CAD or HF. METHODS From June 2010 to June 2013, a total of 487 patients without a history of CAD and HF were enrolled. All of the patients underwent plane multi-detector computed tomography. They were divided into four categories according to CAC scores: ≤10, 11-100, 101-400, and ≥401. RESULTS The proportion of patients with high NT-proBNP levels increased with CAC categories (p<0.0001). The CAC score was associated with NT-proBNP levels ≥400pg/ml, with an odds ratio of 2.901 (95% confidence interval: 1.368-6.151, p=0.0055) for CAC scores ≥401 compared with CAC scores of 0-10 after adjustment for confounding factors. During the follow-up period of 497±315 days, nine patients were admitted for HF. Kaplan-Meier analysis showed that patients with CAC scores ≥401 had a lower rate of freedom from admission for HF with cumulative incidences of 0.4%, 1%, 2%, and 8% for CAC scores of 0-10, 11-100, 101-400, and ≥401, respectively (p<0.0001). Increasing CAC scores were associated with an increase in incidence of admission for HF, with a hazard ratio of 10.371 for CAC scores ≥401 (95% CI: 1.062-101.309, p=0.0443) compared with CAC scores of 0-10 after adjustment for risk factors. CONCLUSION Severe CAC is an independent determinant of high NT-proBNP levels and a predictor of admission for HF in a population without a history of CAD or HF.

Abstract
BACKGROUND Cystatin C is an endogenous marker of kidney function that overcomes the limitations of serum creatinine. High serum cystatin C levels have been associated with increased cardiovascular mortality and morbidity. In this cross-sectional study, we aimed to determine the associations between serum cystatin C levels and structural and functional cardiac changes in patients with stage 2 or 3 chronic kidney disease (CKD). METHODS AND RESULTS We enrolled 429 consecutive patients (aged 24-97 years) with CKD stage 2 or 3 and left ventricular (LV) ejection fraction (LVEF)>40%. Echocardiographic parameters, including LV mass index (LVMI), early diastolic mitral annulus velocity (e' velocity), left atrial volume index (LAVI), and N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) were measured. Patients were categorized into quartiles according to serum cystatin C levels. Cystatin C was associated with LAVI (p=0.0055), LVEF (p=0.0432), LVMI (p=0.0409), e' (p=0.0051), E/e' (p=0.0027), and log-transformed NT-proBNP (p<0.0001) according to multivariate linear regression analysis, after adjustment for confounding factors including creatinine-based estimated glomerular filtration rate (eGFRcreat) and urinary albumin to creatinine ratio. Incidence of eccentric and concentric hypertrophy increased with increasing cystatin C (Q1, 38%; Q2 49%; Q3, 51%; Q4, 66%, p=0.0008), mainly because of increasing concentric hypertrophy (Q1, 30%; Q2, 39%; Q3, 39%; Q4, 51%, p=0.0187). CONCLUSION A high serum cystatin C is strongly associated with structural cardiac abnormalities such as LVH and left atrial enlargement, impaired LV relaxation, and an increased NT-proBNP, independently of eGFRcreat in patients with stage 2 or 3 CKD.

Abstract
The effect of ethacrynic acid (ETA) upon pendular rotation nystagmus and paralytic nystagmus was examined using 61 guinea pigs. 100 mg/kg ETA reduced these nystagmus but 30 mg/kg ETA had on effect. Galvanic nystagmus, Bechterew's compensatory nystagmus, OKN and EEG were not affected by 100 ng/kg ETA. These results are highly suggestive that the inhibition of the peripheral vestibular nystagmus by ETA is mainly due to the reduction of the ampullar endolymphatic potential.

Abstract
Background: Pancreatic cancer has a poor prognosis because of its high refractoriness to chemotherapy and tumour recurrence, and these properties have been attributed to cancer stem cells (CSCs). MicroRNA (miRNA) regulates various molecular mechanisms of cancer progression associated with CSCs. This study aimed to identify the candidate miRNA and to characterise the clinical significance. Methods: We established gemcitabine-resistant Panc1 cells, and induced CSC-like properties through sphere formation. Candidate miRNAs were selected through microarray analysis. The overexpression and knockdown experiments were performed by evaluating the in vitro cell growth and in vivo tumourigenicity. The expression was studied in 24 pancreatic cancer samples after laser captured microdissection and by immunohistochemical staining. Results: The in vitro drug sensitivity of pancreatic cancer cells was altered according to the miR-1246 expression via CCNG2. In vivo, we found that miR-1246 could increase tumour-initiating potential and induced drug resistance. A high expression level of miR-1246 was correlated with a worse prognosis and CCNG2 expression was significantly lower in those patients. Conclusions: miR-1246 expression was associated with chemoresistance and CSC-like properties via CCNG2, and could predict worse prognosis in pancreatic cancer patients.

Abstract
AIMS/HYPOTHESIS The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is an important gene regulator in glucose and lipid metabolism. Unfortunately, PPARγ-activating drugs of the thiazolidinedione class provoke adverse side effects. As recently shown, amorfrutin A1 is a natural glucose-lowering compound that selectively modulates PPARγ. In this study we aimed to characterise, in vitro, a large spectrum of the amorfrutins and similar molecules, which we isolated from various plants. We further studied in vivo the glucose-lowering effects of the so far undescribed amorfrutin B, which featured the most striking PPARγ-binding and pharmacological properties of this family of plant metabolites. METHODS Amorfrutins were investigated in vitro by binding and cofactor recruitment assays and by transcriptional activation assays in primary human adipocytes and murine preosteoblasts, as well as in vivo using insulin-resistant high-fat-diet-fed C57BL/6 mice treated for 27 days with 100 mg kg(-1) day(-1) amorfrutin B. RESULTS Amorfrutin B showed low nanomolar binding affinity to PPARγ, and micromolar binding to the isotypes PPARα and PPARβ/δ. Amorfrutin B selectively modulated PPARγ activity at low nanomolar concentrations. In insulin-resistant mice, amorfrutin B considerably improved insulin sensitivity, glucose tolerance and blood lipid variables after several days of treatment. Amorfrutin B treatment did not induce weight gain and furthermore showed liver-protecting properties. Additionally, amorfrutins had no adverse effects on osteoblastogenesis and fluid retention. CONCLUSIONS/INTERPRETATION The application of plant-derived amorfrutins or synthetic analogues thereof constitutes a promising approach to prevent or treat complex metabolic diseases such as insulin resistance or type 2 diabetes.

Abstract
Background: Gemcitabine-based chemotherapy is the standard treatment for pancreatic cancer. However, the issue of resistance remains unresolved. The aim of this study was to identify microRNAs (miRNAs) that govern the resistance to gemcitabine in pancreatic cancer. Methods: miRNA microarray analysis using gemcitabine-resistant clones of MiaPaCa2 (MiaPaCa2-RGs), PSN1 (PSN1-RGs), and their parental cells (MiaPaCa2-P, PSN1-P) was conducted. Changes in the anti-cancer effects of gemcitabine were studied after gain/loss-of-function analysis of the candidate miRNA. Further assessment of the putative target gene was performed in vitro and in 66 pancreatic cancer clinical samples. Results: miR-320c expression was significantly higher in MiaPaCa2-RGs and PSN1-RGs than in their parental cells. miR-320c induced resistance to gemcitabine in MiaPaCa2. Further experiments showed that miR-320c-related resistance to gemcitabine was mediated through SMARCC1, a core subunit of the switch/sucrose nonfermentable (SWI/SNF) chromatin remodeling complex. In addition, clinical examination revealed that only SMARCC1-positive patients benefited from gemcitabine therapy with regard to survival after recurrence (P=0.0463). Conclusion: The results indicate that miR-320c regulates the resistance of pancreatic cancer cells to gemcitabine through SMARCC1, suggesting that miR-320c/SMARCC1 could be suitable for prediction of the clinical response and potential therapeutic target in pancreatic cancer patients on gemcitabine-based therapy.

Abstract
BACKGROUND AND PURPOSE Dopamine released from the endings of descending dopaminergic nerve fibres in the spinal cord may be involved in modulating functions such as locomotion and nociception. Here, we examined the effects of dopamine on spinal synaptic transmissions in rats. EXPERIMENTAL APPROACH Spinal reflex potentials, monosynaptic reflex potential (MSR) and slow ventral root potential (sVRP), were measured in the isolated spinal cord of the neonatal rat. Dopamine release was measured by HPLC. KEY RESULTS Dopamine at lower concentrations (<1 µM) depressed sVRP, which is a C fibre-evoked polysynaptic response and believed to reflect nociceptive transmission. At higher concentrations (>1 µM), in addition to a potent sVRP depression, dopamine depolarized baseline potential and slightly depressed MSR. Depression of sVRP by dopamine was partially reversed by dopamine D(1) -like but not by D(2) -like receptor antagonists. SKF83959 and SKF81297, D(1) -like receptor agonists, and methamphetamine, an endogenous dopamine releaser, also caused the inhibition of sVRP. Methamphetamine also depressed MSR, which was inhibited by ketanserin, a 5-HT(2A/2C) receptor antagonist. Methamphetamine induced the release of dopamine and 5-HT from spinal cords, indicating that the release of endogenous dopamine and 5-HT depresses sVRP and MSR respectively. CONCLUSION AND IMPLICATIONS These results suggested that dopamine at lower concentrations preferentially inhibited sVRP, which is mediated via dopamine D(1) -like and other unidentified receptors. The dopamine-evoked depression is involved in modulating the spinal functions by the descending dopaminergic pathways.

Abstract
To establish cheese as a dairy product with health benefits, we embarked on examining the multifunctional role of cheeses, especially in the field of cancer prevention. The current study was designed to investigate whether different types of commercial goat cheeses may possess antiproliferative activity, using an HL-60 human promyelocytic leukemia cell line as a cancer cell model. Among 11 cheese extracts tested at 500μg/mL, 6 (Crottin de Chavignol, Pouligny Saint-Pierre, Chabichou du Poitou, Valencay, Kavli, and Sainte-Maure de Touraine) resulted in a significant decrease of cell viability, which is consistent with a decrease in viable cell number. Compared with the half-maximal inhibitory concentration (IC(50)) value of individual cheeses in cellular proliferation assays, the Pouligny Saint-Pierre extract showed strong inhibition. Incubation of cells in the presence of Pouligny Saint-Pierre extract resulted in induction of cellular morphological changes and apoptotic DNA fragmentation as well as expression of the active form of caspase-3 protein. Based on the quantification of the ratio of free fatty acids to triglycerides in different cheese samples, a significant correlation was detected between lipolytic ripeness and IC(50) values for antiproliferative capacity tested in HL-60 cells. Collectively, these results support a potential role of highly lipolyzed goat cheeses in the prevention of leukemic cell proliferation.

Abstract
Computerised modelling methods have become highly useful for generating electronic representations of anatomical structures. These methods rely on crosssectional tissue slices in databases such as the Visible Human Male and Female, the Visible Korean Human, and the Visible Chinese Human. However, these databases are time consuming to generate and require labour-intensive manual digitisation while the number of specimens is very limited. Plastinated anatomical material could provide a possible alternative to data collection, requiring less time to prepare and enabling the use of virtually any anatomical or pathological structure routinely obtained in a gross anatomy laboratory. The purpose of this study was to establish an approach utilising plastinated anatomical material, specifically human hearts, for the purpose computerised 3-D modelling. Human hearts were collected following gross anatomical dissection and subjected to routine plastination procedures including dehydration (-25(o)C), defatting, forced impregnation, and curing at room temperature. A graphics pipeline was established comprising data collection with a hand-held scanner, 3-D modelling, model polishing, file conversion, and final rendering. Representative models were viewed and qualitatively assessed for accuracy and detail. The results showed that the heart model provided detailed surface information necessary for gross anatomical instructional purposes. Rendering tools facilitated optional model manipulation for further structural clarification if selected by the user. The use of plastinated material for generating 3-D computerised models has distinct advantages compared to cross-sectional tissue images.
