Abstract
Background Cases of systemic thromboembolism due to thrombus formation in the pulmonary vein stump after lobectomy have been reported recently. Cerebral infarction after left upper lobectomy is a common symptom in these cases. We encountered a rare case of acute limb ischemia caused by a thrombus formed in the left inferior pulmonary vein stump after left lower lobectomy. Case presentation A 62-year-old man underwent video-assisted left lower lobectomy under general anesthesia with epidural anesthesia. On postoperative day 2, he suddenly developed pain in the left calf. Contrast-enhanced computed tomography showed left popliteal artery occlusion and thrombus formation in the left inferior pulmonary vein stump. Anticoagulant therapy was started immediately, and emergent endovascular thrombectomy was performed. The patient recovered without complications. Conclusions Left lower lobectomy can cause thrombus formation in the pulmonary vein stump, leading to systemic thromboembolism. Early detection and treatment are the keys to minimize complications.

Abstract
OBJECTIVE To determine whether to perform decompression prior to resection in cases of bowel obstruction due to colorectal cancer. SUBJECTS There were 83 patients who underwent resection to treat a bowel obstruction due to colorectal cancer from January 2006 to August 2016. Clinical aspects and the prognosis for colorectal cancer were examined in patients who underwent decompression prior to resection and those who did not. RESULTS Of the 83 patients, 50 underwent decompression whereas 33 did not. Patients who did not undergo decompression most often had cancer in the right colon. Surgery took longer for patients who underwent decompression; some had extensive blood loss. Patients who underwent decompression were hospitalized for significantly longer. Patients who did not undergo decompression with an obstruction of the left colorectum due to cancer had more severe complications. DFS and OS did not differ significantly in patients with a bowel obstruction due to colorectal cancer. OS did not differ significantly for patients with an obstruction of the left colorectum due to cancer, but DFS was better for patients who underwent decompression. CONCLUSION Patients with an obstruction of the left colorectum due to cancer should undergo decompression prior to resection.

Abstract
The localization of charge carriers by electronic repulsion was suggested by Mott in the 1930s to explain the insulating state observed in supposedly metallic NiO. The Mott metal-insulator transition has been subject of intense investigations ever since1-3-not least for its relation to high-temperature superconductivity4. A detailed comparison to real materials, however, is lacking because the pristine Mott state is commonly obscured by antiferromagnetism and a complicated band structure. Here we study organic quantum spin liquids, prototype realizations of the single-band Hubbard model in the absence of magnetic order. Mapping the Hubbard bands by optical spectroscopy provides an absolute measure of the interaction strength and bandwidth-the crucial parameters that enter calculations. In this way, we advance beyond conventional temperature-pressure plots and quantitatively compose a generic phase diagram for all genuine Mott insulators based on the absolute strength of the electronic correlations. We also identify metallic quantum fluctuations as a precursor of the Mott insulator-metal transition, previously predicted but never observed. Our results suggest that all relevant phenomena in the phase diagram scale with the Coulomb repulsion U, which provides a direct link to unconventional superconductivity in cuprates and other strongly correlated materials.

Abstract
OBJECTIVES Platinum-based combination chemotherapy is the standard postoperative adjuvant treatment for pathological stage II/III non-small cell lung cancer (NSCLC). Oral S-1 therapy has good efficacy and relatively low toxicity for the treatment of advanced NSCLC. We investigated whether long-term S-1 monotherapy is also useful as an adjuvant therapy after surgery in patients with NSCLC. PATIENTS AND METHODS We conducted a phase II randomized open-label multi-institutional study in patients with pathological stage II/IIIA NSCLC (7th TNM classification) who underwent complete resection from 2009 to 2013. The primary endpoint, the 2-year disease-free survival (DFS) rate, was evaluated using the Bayesian method. Eligible patients were randomly assigned to two arms: oral S-1 monotherapy (S-1 arm) and S-1 plus cisplatin combination therapy followed by S-1 (S-1 plus cisplatin arm) both for a total of 1 year. RESULTS A total of 70 and 71 patients were enrolled in S-1 arm and S-1 plus cisplatin arm, respectively. The 2-year DFS rates were 52% (95% confidence interval [CI], 0.40-0.63) and 61% (95% CI, 0.48-0.70) for S-1 arm and S-1 plus cisplatin arm, respectively. Both arms met the primary endpoint. Neither DFS nor OS was significantly different between the arms (log-rank test: P = 0.1695 and P = 0.8684, respectively). The main G3/4 adverse events were loss of appetite and anemia (S-1 vs. S-1 plus cisplatin: 4.3% vs. 11.6% and 0% vs. 5.8%, respectively). The treatment completion rate did not differ between the two arms (S-1 vs. S-1 plus cisplatin: 45.7%, 95% CI, 41.9-66.3% vs. 43.5% 95% CI, 44.0-68.4%). CONCLUSIONS Long-term adjuvant chemotherapy with S-1 was a feasible and promising treatment for patients with completely resected NSCLC, regardless of cisplatin addition. S-1 monotherapy should be investigated further, based on its low toxicity and practical convenience.

Abstract
In this work, we report the synthesis of novel fluorescent molecules, based on 1,8-naphthalimide thio- and amino-derivatives, designed to display an OFF-ON and ON-OFF photoelectron transfer fluorescence switch upon interaction with a proton-donor drug. We have functionalized the new probes to allow easy formation of a covalent link to polymer matrices, for future applications as drug delivery sensors. We have investigated the fluorescent switch of the new probes using flufenamic acid (FA, pKa 3.65), a water insoluble, non-steroidal anti-inflammatory drug, as a model drug and proton source. The rapid interaction of the new probes with FA resulted in fluorescence enhancement or decrease and a large Stokes shift, all of which allowed the detection of the drug in the nanomolar range. The new 1,8-naphthalimide fluorescent dyes reported in this work are interesting tools for the detection and quantification of acidic drugs and biomolecules.

Abstract
Purpose Preoperative chemoradiotherapy (CRT) using 5-fluorouracil (5-FU)-based chemotherapy is the standard of care for rectal cancer. The effect of additional chemotherapy during the period between the completion of radiotherapy and surgery remains unclear. Predictive factors for CRT may differ between combination chemotherapy with S-1 and with tegafur-uracil/leucovorin (UFT/LV). Methods The subjects were 54 patients with locally advanced rectal cancer who received preoperative CRT with S-1 or UFT/LV. The pathological tumor response was assessed according to the tumor regression grade (TRG). The expression levels of 18 CRT-related genes were determined using RT-PCR assay. Results A pathological response (TRG 1-2) was observed in 23 patients (42.6%). In a multivariate logistic regression analysis for pathological response, the overall expression levels of four genes, HIF1A, MTHFD1, GGH and TYMS, were significant, and the accuracy rate of the predictive model was 83.3%. The effects of the gene expression levels of GGH on the response differed significantly according to the treatment regimen. The total pathological response rate of both high-GGH patients in the S-1 group and low-GGH patients in the UFT/LV group was 58.3%. Conclusion Additional treatment with 5-FU-based chemotherapy during the interval between radiotherapy and surgery is not beneficial in patients who have received 5-FU-based CRT. The expression levels of four genes, HIF1A, MTHFD1, GGH and TYMS, in tumor tissues can predict the response to preoperative CRT including either S-1 or UFT/LV. In particular, the gene expression level of GGH in tumor tissues may be a useful biomarker for the appropriate use of S-1 and UFT/LV in CRT.

Abstract
Differential Scanning Calorimetry (DSC) and optical polarization microscopy of a mixture of the liquid crystalline material (N-(4-methoxybenzylidene)-4-butylaniline, MBBA) and a Fe-based room temperature ionic liquid 1-ethyl-3-methylimidazolium tetrachloroferrate ([Emim](+) [FeCl4](-), EMIF) indicate a decrease in the nematic-isotropic (N-I) phase transition temperature (T(NI)) with an increase in EMIF concentration, explained by a proposed model of Coulomb "screening" of MBBA quadrupoles by the EMIF ions along with ionic "self screening." DSC studies of EMIF-MBBA and pure EMIF and comparison with pure MBBA results show that the major transitions in pure EMIF have Arrhenius behaviour, but more importantly the previously found convex Arrhenius behaviour of the pristine MBBA [K. Dan et al., Europhys. Lett. 108, 36007 (2014)] becomes Arrhenius in the mixture, indicating a conversion of the entropic N-I activation barrier to an enthalpic one. In presence of EMIF, a drastic decrease in the intensity of out-of-plane distortions of benzene rings in MBBA is found from Fourier transform infrared spectroscopy, consistent with significant reduction in the conformational states of MBBA. This suppression of large amplitude motion is again consistent with a Coulomb screening and gives a molecular basis for the entropic-to-enthalpic conversion of the N-I activation barrier.

Abstract
A 63-year-old woman underwent a low anterior resection for rectal cancer in 2002.A n anastomotic recurrence was diagnosed in July 2011.S he rejected the possibility of colostomy as radical surgery.Chemotherapy consisting of capecitabine+ oxaliplatin (XELOX) or folinic acid, fluorouracil, and oxaliplatin (FOLFOX6) + bevacizumab were not possible because of high costs. In view of the lower costs and the potential for ambulation, S-1 monotherapy was started. After 3 months, a reduction in the recurrent lesion was observed.After 19 months, the recurrent lesion revealed a scar, which was judged by biopsy to be Group 1.We had achieved a pathological complete response (CR).The standard treatment for recurrent colon cancer is surgical resection or multidrug chemotherapy. However, in view of a patient's quality of life (QOL), S-1 monotherapy may be considered as a potential therapy.

Abstract
ABSTRACTThin films of a charge transfer complex, hepta-(tetrathiafulvalene) pentaiodide ( TTF7I5, TTF:I0-71 ), were prepared by double source evaporation of TTF and iodine. Crystalline films of TTF:I0-7i were obtained when substrate temperatures were kept between 0°C and 25°C. Orientation alignment of the crystalline films were affected by supply rate of iodine. By controlling the substrate temprature and the supply rate of iodine, highly oriented crystalline films were grown on mica substrates. It showed strong dichroism and anisotropic electrical propert ies.

Abstract
A 65-year-old woman, who had been operated by subtotal esophagectomy for esophageal cancer, was diagnosed as multiple liver metastases and celiac lymph node metastases one year after operation. The response evaluation revealed progressive disease after she had been suffering from nausea and anorexia throughout 2 courses of FP therapy. She refused to continue any more systemic chemotherapy, so we proposed an alternative to her, hepatic arterial infusion chemotherapy (HAI) for multiple liver metastases and radiation therapy for celiac LN metastases. Despite the marked reduction of all target lesions and maintenance of tumor marker level below the normal limits after 50 Gy of irradiation and 5 courses of HAI, a novel solitary tumor had appeared in S3 of the liver and an abdominal pain during HAI had occurred at the end of 5th course of HAI. The angiogram revealed occlusion of hepatic artery, suggesting that the emergence of new lesion was attributed to unequal distribution of the drug. Six weeks after a cessation of HAI, a subsequent CT scan showed a rapidly enlarged new lesion in S3, so that a surgical resection for this tumor was performed. The patient is alive without recurrence more than 10 months after the diagnosis of multiple liver metastases (2 months after the last surgery).

Abstract
We reported 2 cases of acute pulmonary embolism after resection for lung cancer. A 47-year-old male was admitted to our hospital with ground-glass opacity (GGO) on a chest computed tomography (CT). We performed a right upper lobectomy and node dissection (ND) 2a dissection. Two days after the operation, he developed hypotension and hypoxemia. He was diagnosed as acute pulmonary embolism by chest CT and lung scintigram. A 68-year-old women was performed right S6 segmentectomy for lung cancer. The next day, she complained of sudden chest discomfort and dyspnea. She was diagnosed as acute pulmonary embolism by chest CT. Immediately, we started anticoagration therapy with heparin and their condition were improved. It was very important to early diagnose and start anticoagration therapy immediately for acute pulumonary embolism.

Abstract
The pressure-temperature phase diagram of the organic Mott insulator kappa-(ET)2Cu2(CN)3, a model system of the spin liquid on triangular lattice, has been investigated by 1H NMR and resistivity measurements. The spin-liquid phase is persistent before the Mott transition to the metal or superconducting phase under pressure. At the Mott transition, the spin fluctuations are rapidly suppressed and the Fermi-liquid features are observed in the temperature dependence of the spin-lattice relaxation rate and resistivity. The characteristic curvature of the Mott boundary in the phase diagram highlights a crucial effect of the spin frustration on the Mott transition.

Abstract
1H NMR and static susceptibility measurements have been performed in an organic Mott insulator with a nearly isotropic triangular lattice, kappa-(BEDT-TTF)2Cu2(CN)(3), which is a model system of frustrated quantum spins. The static susceptibility is described by the spin S=1/2 antiferromagnetic triangular-lattice Heisenberg model with the exchange constant J approximately 250 K. Regardless of the large magnetic interactions, the 1H NMR spectra show no indication of long-range magnetic ordering down to 32 mK, which is 4 orders of magnitude smaller than J. These results suggest that a quantum spin liquid state is realized in the close proximity of the superconducting state appearing under pressure.

Abstract
Listeriolysin O (LLO), a sulfhydryl-activated pore-forming protein from Listeria monocytogenes, was tested and utilized for promoting plasmid DNA (pDNA) delivery into the cytosol of cells in culture. To render pDNA-complexing capability to LLO, the unique cysteine 484 of LLO was conjugated to polycationic peptide protamine (PN) at a 1:1 molar ratio through a reversible, endosome-labile disulfide bond. The sulfhydryl-oxidized LLO construct, LLO-s-s-PN, completely lacked its pore-forming activity, yet regained its original activity upon reduction. The enhanced cytosolic delivery using this construct therefore relies on the requisite reduction of the disulfide bond in LLO-s-s-PN by endogenous cellular reducing capacity. Condensed PN/pDNA complexes incorporating LLO-s-s-PN were tested for their enhanced gene delivery capability monitoring reporter gene expression in HEK293, RAW264.7, P388D1 cell lines and bone-marrow-derived macrophages in the presence of serum. Dramatic enhancement was observed for all tested complexes with varying weight ratios. The effect was most prominent at 0.64-0.80 (w/w) of PN/pDNA upon replacing 1-4% of PN with LLO-s-s-PN, resulting in approximately three orders of magnitude higher luciferase expression compared to PN/pDNA without apparent toxicity. These results demonstrate that incorporation of endosomolytic LLO into pDNA delivery systems in a controlled fashion is a promising approach of enhancing delivery into the cytosol of target cells in gene delivery strategies.

Abstract
Large-scale mapping observations of the 3P1-3P0 fine-structure transition of atomic carbon (C i, 492 GHz) and the J=3-2 transition of CO (346 GHz) toward the Orion A molecular cloud have been carried out with the Mount Fuji submillimeter-wave telescope. The observations cover 9 deg2 and include the Orion Nebula M42 and the L1641 dark cloud complex. The C i emission extends over almost the entire region of the Orion A cloud and is surprisingly similar to that of 13CO (J=1-0). The CO (J=3-2) emission shows a more featureless and extended distribution than C i. The C i/CO (J=3-2) integrated intensity ratio shows a spatial gradient running from the north (0.10) to the south (1.2) of the Orion A cloud, which we interpret as a consequence of the temperature gradient. On the other hand, the C i/13CO (J=1-0) intensity ratio shows no systematic gradient. We have found a good correlation between the C i and 13CO (J=1-0) intensities over the Orion A cloud. This result is discussed on the basis of photodissociation region models.

Abstract
We report a case of squamous cell carcinoma of the lung in which a left pneumonectomy combined resection of the pulmonary artery and aorta was performed using a cardiopulmonary bypass. The bifurcation of the pulmonary artery was repaired with a pericardial patch and the descending aorta was replaced with an artificial vessel Eleven months later, the patient underwent dissection of the contralateral mediastinal lymph nodes because of a recurrence of the disease. Even though pulmonary metastases have again recently appeared, he is alive and doing well two years after operation. To obtain a better prognosis in cases demonstrating an involvement of the bifurcation of pulmonary artery, more effective combined treatment still needs to be developed.

Abstract
The present study characterized Chinese hamster ovary cells overexpressing a human intestinal peptide transporter, CHO/hPEPT1 cells, as an in vitro model for peptidomimetic drugs. The kinetic parameters of Gly-Sar uptake were determined in three different cell culture systems such as untransfected CHO cells (CHO-K1), transfected CHO cells (CHO/hPEPT1) and Caco-2 cells. Vmax in CHO/hPEPT1 cells was approximately 3-fold higher than those in Caco-2 cells and CHO-K1 cells, while Km values were similar in all cases. The uptake of beta-lactam antibiotics in CHO/hPEPT1 cells was three to twelve fold higher than that in CHO-K1 cells, indicating that CHO/hPEPT1 cells significantly enhanced the peptide transport activity. However, amino acid drugs also exhibited high cellular uptake in both CHO-K1 and CHO/hPEPT1 cells due to the high background level of amino acid transporters. Thus, cellular uptake study in CHO/hPEPT1 cells is not sensitive enough to distinguish the peptidyl drugs from amino acid drugs. The potential of CHO/hPEPT1 cells as an in vitro model for peptidomimetic drugs was also examined through the inhibition study on Gly-Sar uptake. Peptidomimetic drugs such as beta-lactam antibiotics and enalapril significantly inhibited Gly-Sar uptake whereas the nonpeptidyl compounds, L-dopa and alpha-methyldopa, did not compete with Gly-Sar for cellular uptake within the therapeutic concentrations. In conclusion, the present study demonstrates the further characterization of CHO/hPEPT1 cells as an uptake model as well as inhibition study and suggests their utility as an alternative in vitro model for drug candidates targeting the hPEPT1 transporter.

Abstract
A case of biphasic type pulmonary blastoma in a 59-year-old man is reported. Although the tumour was radically resected, there was rapid metastasization to the neck, mediastinum, liver and multiple bones. Despite radiotherapy, the patient died about 14 months postoperatively. Close follow-up and aggressive chemotherapy should be considered for such tumours.

Abstract
Sclerosing sweat-duct carcinoma is a rare malignancy of the skin. We herein present the case of a 68-year-old Japanese man who developed sclerosing sweat-duct carcinoma 2 years after undergoing local excision of a primary tumor in his right arm. Firm nodules appeared in the right axilla, which were revealed by surgical resection to be metastases. This rare tumor grows slowly but usually metastasizes to the regional lymph nodes, whereupon they are often associated with a poor prognosis. As the effectiveness of chemotherapy and radiotherapy against this neoplasm remains unclear, we recommend that the disease should initially be aggressively treated by surgery, which would also be indicated for any metastatic lesions.
