Abstract
Abstract
Background: E-cadherin and vimentin are now regarded as major and conventional canonical markers of epithelial-mesenchymal transition (EMT). It is commonly assumed E-cadherin is uniformly lost during the process of EMT. We previously reported that the elevated expression of vimentin contributes to the aggressive phenotype in invasive breast cancer. On the other hand, the role of E-cadherin in breast cancer biology might be unclear and more complex. Although, cell cohesion during breast cancer invasion is often overlooked, accumulating evidences indicate breast tumor cells are typically cohesive and often display membrane-localized E-cadherin in both the primary tumor and distant metastases, termed collective invasion. Multiple mechanisms have emerged to address how epithelial breast tumors invade.
Aims: The aim of this study is to reveal the clinical importance of the expression pattern of E-cadherin and vimentin in breast cancer.
Methods: The E-cadherin and vimentin protein expression were evaluated by immunohistochemistry (IHC) in 177 invasive breast cancer samples. Among these, E-cadherin and vimentin expression were evaluated in the set of primary breast cancer and metastatic lymph nodes in 65 cases. In addition, E-cadherin and vimentin expression were analyzed by immunofluorescent staining and evaluated using confocal laser scanning microscopy to see E-cadherin and vimentin localization in the breast cancer cells.
Results: The positive vimentin expression was highly correlated with poor disease-free survival (DFS) and overall survival (OS) (p=0.019 and p=0.0044), however, the E-cadherin expression alone did not correlate with prognosis. Interestingly, both E-cadherin and vimentin positive tumors had the worst DFS and OS among all breast cancer (p=0.03 and p=0.0089). Vimentin expression was highly correlated between primary tumors and metastatic lymph nodes. However, E-cadherin expression levels were significantly elevated in metastatic lymph nodes (p=0.0017). Co-expression of E-cadherin and vimentin in the metastatic lymph nodes also showed worst DFS and OS (p=0.12 and p=0.027).Immunofluorescent analysis revealed that E-cadherin and vimentin were co-localized within the same tumor cells in many of the E-cadherin high/vimentin positive tumors.
Conclusions: Co-expression of E-cadherin and vimentin seems to be associated with the most aggressive phenotype and poorest prognosis in breast cancer. Moreover, co-localization of E-cadherin and vimentin within the same breast cancer cells suggests the significance of the expressions of both proteins in breast cancer invasion and metastasis.

Abstract
Abstract
Backgrounds; The wild-type p53-induced phosphatase 1(Wip1) is a member of the serine/threonine protein phosphatases, and plays an important role in the nucleus as one of the key components in the DNA damage response network. Wip1 is encoded by the protein phosphatase magnesium dependent 1 delta (PPM1D), sited on locus 17q23. PPM1D gene amplification and/or Wip1 expression have been observed in numerous tumors, including breast cancer. PPM1D is referred to as oncogene, as Wip1 inhibits phosphorylation of p53 and work as a negative regulator in cell death. Inhibition of Wip1 may have an important therapeutic role in suppressing tumor growth and evolution.
Aims; We evaluated the expression of Wip1 mRNA, Wip1 protein and PPM1D DNA copy number to clarify the relationship between Wip1 expression and the clinicopathological features and prognosis to determine the biological significance of Wip1.
Materials and Methods; Breast cancer cell lines (MCF7, T47D, MDA-MB231, HCC1937, HS578T, BT20 and SKBr3) were used for Wip1 expression analysis and copy number analysis. The specimens were obtained from Japanese breast cancer patients who underwent surgery without neoadjuvant chemotherapy or endocrine therapy in our department. Wip1 mRNA expression was evaluated in 140 cases by quantitative RT-PCR and Wip1 protein expression was evaluated in 192 cases by immunohistochemistry (IHC). The PPM1D DNA copy number was analyzed by genomic PCR in 33 breast cancer cases and by SNP-CGH array (Illumina, Human Omni 2.5-8) in 12 cases. The effects on the cell growth of the Wip1 inhibitor (GSK2830371) were analyzed by the viability assay in MCF7.
Results; Wip1 mRNA expression was significantly higher in MCF7, luminal type cell line. There was no significant correlation between Wip1 mRNA expression and prognosis. In IHC, positive nuclear Wip1 protein expression was detected in 21 cases (10.9%). There was no significant correlation between Wip1 mRNA expression and Wip1 protein expression. There was no significant association between the Wip1 protein expression levels and the clinicopathological factors and the prognosis. PPM1D DNA copy number significantly correlated with Wip1 protein expression (p=0.0035). Copy number gain at 17q23 was detected in 6 cases by SNP-CGH array, and all of these six cases showed positive nuclear Wip1 expression. PPM1D copy number gain was not observed in Wip1 negative cases. In the cell viability assay, the MCF7 cell growth was suppressed by Wip1 inhibitor administration.
Conclusions;Wip1 protein expression in nucleus is important as oncogene, and its expression may be regulated by PPM1D copy number gain. Wip1 is considered to be the new therapeutic target for breast cancer patients.

Abstract
BACKGROUND AND AIMS Peripheral artery disease in dialysis cases is more prone to critical limb ischemia compared to non-dialysis cases, with a significantly high rate of major amputation of the lower limbs. Lesions are distributed on the more distal side in dialysis critical limb ischemia cases. The aim of this study was to investigate the usefulness of indocyanine green angiography to determine differences in the regional circulation in the foot between dialysis and non-dialysis patients. MATERIALS AND METHODS The subjects included 62 cases, among which 20 were dialysis patients and 42 were non-dialysis patients. We compared the indocyanine green angiography parameters for regions of interest in the dialysis and non-dialysis groups, which included the magnitude of intensity from indocyanine green onset to maximum intensity (Imax), the time from indocyanine green onset to maximum intensity (Tmax), the time elapsed from the fluorescence onset to half the maximum intensity (T1/2), and the time from maximum intensity to declining to 90% of the maximum intensity (Td90%). These indocyanine green angiography parameters were measured at region of interest 1 (the Chopart joint), region of interest 2 (the Lisfranc joint), and region of interest 3 (the distal region of the first metatarsal bone). RESULTS In the comparison between the dialysis and non-dialysis groups, a significant difference was observed regarding Tmax, T1/2, and Td90%, especially in region of interest 3. CONCLUSION In this study, we show that regional tissue perfusion is more deteriorated in dialysis patients compared with non-dialysis patients using indocyanine green angiography. Tmax, T1/2, and Td90% could be useful clinical parameters to compare ischemic severity of the lower limb between dialysis and non-dialysis patients.

Abstract
BACKGROUND Circulating microRNAs (miRNAs) are attracting major interest as potential non-invasive biomarkers for colorectal cancer (CRC). This study aimed to identify a novel serum miRNA biomarker for the early detection and/or evaluating prognosis of CRC patients. PATIENTS AND METHODS Comprehensive miRNA array analysis was carried out using serum samples from patients with colorectal neoplasia and healthy controls. Next, to verify whether the candidate miRNA possessed a secretory potential, we screened miRNA expression levels in culture medium from 2 CRC cell lines, followed by serum analysis from 12 stage IV CRC, 12 adenoma, and 12 control subjects. Thereafter, we validated expression of candidate miRNAs in 179 primary CRC tissues, as well as serum samples from an independent cohort of 211 CRCs, 56 adenomas, and 57 control subjects. RESULTS Through microarray analysis, we identified significantly higher levels of miRNA-1290 (miR-1290) in serum from patients with colorectal adenomas and cancers. We verified miR-1290 overexpression in serum of CRC patients in a training cohort. In the validation cohort, serum miR-1290 levels were significantly up-regulated in patients with colorectal adenomas (P < 0.0001) and cancers (P < 0.0001). Serum miR-1290 levels could robustly distinguish adenoma [area under the curve (AUC) = 0.718] and CRC patients (AUC = 0.830) from normal subjects. High miR-1290 expression in serum and tissue was significantly associated with tumor aggressiveness and poor prognosis. Moreover, serum miR-1290 levels were an independent prognostic factor [hazard ratio (HR) = 4.51; 95% confidence interval (CI) = 1.23-23.69; P = 0.0096] and an independent predictor for tumor recurrence (hazard ratio = 3.92; 95% confidence interval = 1.11-25.14; P = 0.032) in CRC. CONCLUSIONS Serum miR-1290 is a novel biomarker for early detection, recurrence, and prognosis in CRC.

Abstract
BACKGROUND Ankle brachial index (ABI), toe pressures (TP), and transcutaneous oxygen pressure (TcPO2) are traditionally used in the assessment of critical limb ischemia (CLI). Indocyanine green (ICG) fluorescence imaging can be used to evaluate local circulation in the foot and to evaluate the severity of ischemia. This prospective study analyzed the suitability of a fluorescence imaging system (photodynamic eye [PDE]) in CLI. MATERIAL AND METHODS Forty-one patients with CLI were included. Of the patients, 66% had diabetes and there was an ischemic tissue lesion in 70% of the limbs. ABI, toe pressures, TcPO2 and ICG-fluorescence imaging (ICG-FI) were measured in each leg. To study the repeatability of the ICG-FI, each patient underwent the study twice. After the procedure, foot circulation was measured using a time-intensity curve, where T1/2 (the time needed to achieve half of the maximum fluorescence intensity) and PDE10 (increase of the intensity during the first 10 s) were determined. A time-intensity curve was plotted using the same areas as for the TcPO2 probes (n=123). RESULTS The mean ABI was 0.43, TP 21 mmHg, TcPO2 23 mmHg, T1/2 38 s, and PDE10 19 AU. Time-intensity curves were repeatable. In a Bland-Altman scatter plot, the 95% limits of agreement of PDE10 was 9.9 AU and the corresponding value of T1/2 was 14 s. Correlation between ABI and TP was significant (R=.73, p<.001), and it was weaker in diabetic patients (R=.47, p=.048) compared with non-diabetic patients (R=.89, p=.002). Correlations between ABI and TcPO2 and TP and TcPO2 were weak (R=.37, p=.05 and R=.43, p=.037, respectively). Correlation between TcPO2 and PDE10 was strong in diabetic patients (R=.70, p=.003). CONCLUSIONS According to this pilot study, ICG-FI with PDE can be used in the assessment of blood supply in the ischemic foot.

Abstract
Objective: To review series of cases in which surgery was used to treat popliteal vein entrapment (PVE). Methods: Between 1984 and 2001, 11 patients (all women; mean age 27.6 years; 14 limbs) underwent surgery for PVE causing calf ache, swelling, and tenderness of the popliteal fossa. Preoperative evidence of PVE included positive results on a passive dorsi-flexion test, compression of the popliteal vein on ascending venography, hypertrophied or aberrant muscle in the popliteal fossa on CT scanning and elevated below-knee venous pressure. The medial or third head of the gastrocnemius muscle was partly or totally resected under the guidance of intraoperative venous pressure measurement and venography. Results: No operative complications occurred. During 3-10 years of follow-up, 57% of limbs were symptom-free, 21% were improved and 21% were unchanged. Conclusion: Treatment of PVE by resection of muscle fibres under the guidance of objective intraoperative assessments was effective in most patients.

Abstract
Pharmacokinetic exposures to fexofenadine (FEX) are reduced by apple juice (AJ); however, the relationship between the AJ volume and the degree of AJ‐FEX interaction has not been understood. In this crossover study, 10 healthy subjects received single doses of FEX 60 mg with different volumes (150, 300, and 600 mL) of AJ or water (control). To identify an AJ volume lacking clinically meaningful interaction, we tested a hypothesis that the 90% confidence interval (CI) for geometric mean ratio (GMR) of FEX AUCAJ/AUCwater is contained within a biocomparability bound of 0.5–2.0, with at least one tested volume of AJ. GMR (90% CI) of AUCAJ 150mL/AUCwater, AUCAJ 300mL/AUCwater, and AUCAJ 600mL/AUCwater were 0.903 (0.752–1.085), 0.593 (0.494–0.712), and 0.385 (0.321–0.462), respectively. While a moderate to large AJ‐FEX interaction is caused by a larger volumes of AJ (e.g., 300 to 600 mL), the effect of a small volume (e.g., 150 mL) appears to be not meaningful.

Abstract
Introduction: Lamotrigine is one of several mood stabilizers and its effects for the treatment and prevention of depressive episodes, particularly in bipolar disorder, are generally accepted. Although the findings about a therapeutic window of lamotrigine are yet to be determined, it seems important to obtain information on individual pharmacokinetic peculiarities. This study was conducted to formulate the predictive model of plasma lamotrigine levels. Methods: Using the data of 47 patients whose lamotrigine levels, liver function, and renal function were measured, predictive models of lamotrigine levels were formulated by stepwise multiple regression analyses. The predictive power of the models was compared using another dataset of 25 patients. Results: Two models were created using stepwise multiple regression. The first model was: plasma lamotrigine level (μg/mL)=2.308+0.019×lamotrigine dose (mg/day). The second model was: plasma lamotrigine level (μg/mL)=0.08+0.024×lamotrigine dose (mg/day)+4.088×valproate combination (no=0, yes=1). The predictive power of the second model was better than that of the first model. Discussion: The present study proposes a prompt and relatively accurate equation to predict lamotrigine levels.

Abstract
BACKGROUND AND PURPOSE Cerebral hyperperfusion syndrome is a potential complication of superficial temporal artery-MCA anastomosis for Moyamoya disease. In this study, we evaluated whether TOF-MRA could assess cerebral hyperperfusion syndrome after superficial temporal artery-MCA anastomosis for this disease. MATERIALS AND METHODS This retrospective study included patients with Moyamoya disease who underwent superficial temporal artery-MCA single anastomosis. TOF-MRA and SPECT were performed before and 1-6 days after anastomosis. Bilateral ROIs on the source image of TOF-MRA were manually placed directly on the parietal branch of the superficial temporal artery just after branching the frontal branch of the superficial temporal artery and on the contralateral superficial temporal artery on the same axial image, respectively. The change ratio of the maximum signal intensity of the superficial temporal artery on TOF-MRA was calculated by using the following formula: (Postoperative Ipsilateral/Postoperative Contralateral)/(Preoperative Ipsilateral/Preoperative Contralateral). RESULTS Of 23 patients (26 sides) who underwent the operation, 5 sides showed cerebral hyperperfusion syndrome postoperatively. There was a significant difference in the change ratio of signal intensity on TOF-MRA observed between the cerebral hyperperfusion syndrome and non-cerebral hyperperfusion syndrome groups (cerebral hyperperfusion syndrome group: 1.88 ± 0.32; non-cerebral hyperperfusion syndrome group: 1.03 ± 0.20; P = .0009). The minimum ratio value for the cerebral hyperperfusion syndrome group was 1.63, and the maximum ratio value for the non-cerebral hyperperfusion syndrome group was 1.30. Thus, no overlap was observed between the 2 groups for the change ratio of signal intensity on TOF-MRA. CONCLUSIONS Diagnosis of cerebral hyperperfusion syndrome is indicated by an increase in the change ratio of signal intensity on TOF-MRA by more than approximately 1.5 times the preoperative levels.

Abstract
Background.
The estrogen receptor (ER)/ GATA3/ Forkhead box A1 (FOXA1) network is necessary for the ERα functional signature specific to luminal type breast cancers. High expression of FOXA1 indicates a good prognosis in ER-positive breast cancer. However, little is known about the association between the expression of FOXA1 and GATA3, and the efficacy of neoadjuvant endocrine therapy (NAE). This study investigated their predictive potential for NAE and the changes of their expression after NAE.
Methods.
The expression of ER, progesterone receptor (PgR), Ki67, FOXA1, and GATA3 were analyzed by immunohistochemistry in 66 patients with hormone receptor-positive/ human epidermal growth factor receptor 2 (HER2)-negative breast cancer who had been treated with NAE between March 2003 and December 2012 at Kyushu University Hospital, National Kyushu Cancer Center, and Sagara Hospital. The association between the expression of biological marker and the efficacy of NAE, and their expression changes after NAE were evaluated.
Results.
The median age of the patients was 60 years (range, 30–84 years). Pre- and post-menopausal patients were 24 (36.4%) and 42 (63.6%). Endocrine agents that were administered are as follows: aromatase inhibitors (AIs) for 42 patients (63.6%), luteinizing hormone-releasing hormone (LHRH) agonist plus AI for 10 patients (15.2%), LHRH agonist plus tamoxifen for 13 patients (19.7%). NAE yielded a partial response (PR) in 21 patients (31.8%) and stable disease (SD) in 45 patients (68.2%). Breast conserving surgery was performed in 56 patients (84.8%) and mastectomy was performed in 10 patients (15.2%). Preoperative Endocrine Prognostic Index (PEPI) score was 0 in 10 patients (15.2%) and 1 or greater (score 1 ≤) in 56 patients (84.8%).
Pre-treatment FOXA1 expression was positively correlated with GATA3 (P = 0.0003) and PgR (P = 0.0138). Post-treatment Ki67 expression was significantly lower in tumors, which achieved PR compared with those with SD (P = 0.0007). The expression of PgR, Ki67, and FOXA1 was significantly lower in post-treatment tumors compared with those in pre-treatment samples (p < 0.0001, p < 0.0001 and p < 0.0001, respectively). The expression of PgR, Ki67, and FOXA1 was significantly reduced in both tumors with PR and those with SD (PR: P = 0.0004, P < 0.0001, and P = 0.0417, respectively; SD: P < 0.0001, P = 0.0001, and P < 0.0001, respectively). The expression of PgR, Ki67, and FOXA1 was significantly decreased in post-treatment tumors in both patients with the PEPI score 0 and those with score 1 ≤ (score 0: P = 0.0078, P = 0.0059, and P = 0.0098, respectively; score 1 ≤: P < 0.0001, P < 0.0001, and P = 0.0002, respectively). In tumors with PgR > 20%, the expression of Ki67 and FOXA1 were significantly lower in post-treatment tumors (P < 0.0001 and P < 0.0001, respectively).
Conclusions.
FOXA1 expression correlated with PgR expression, and was reduced significantly after NAE. These results suggest that blocking the effect of estrogen might reduce FOXA1 expression.

Abstract
When a rubrene crystal was excited with an intense fs pulse (397 nm), transient local heating (∼ps) of the crystal through nonradiative relaxation from SN to S1 accelerates singlet fission of the S1.
