Abstract
The aim of this study is to prepare redox-sensitive nanophotosensitizers for the targeted delivery of chlorin e6 (Ce6) against cervical cancer. For this purpose, Ce6 was conjugated with β-cyclodextrin (bCD) via a disulfide bond, creating nanophotosensitizers that were fabricated for the redox-sensitive delivery of Ce6 against cancer cells. bCD was treated with succinic anhydride to synthesize succinylated bCD (bCDsu). After that, cystamine was attached to the carboxylic end of bCDsu (bCDsu-ss), and the amine end group of bCDsu-ss was conjugated with Ce6 (bCDsu-ss-Ce6). The chemical composition of bCDsu-ss-Ce6 was confirmed with 1H and 13C NMR spectra. bCDsu-ss-Ce6 nanophotosensitizers were fabricated by a dialysis procedure. They formed small particles with an average particle size of 152.0 ± 23.2 nm. The Ce6 release rate from the bCDsu-ss-Ce6 nanophotosensitizers was accelerated by the addition of glutathione (GSH), indicating that the bCDsu-ss-Ce6 nanophotosensitizers have a redox-sensitive photosensitizer delivery capacity. The bCDsu-ss-Ce6 nanophotosensitizers have a low intrinsic cytotoxicity against CCD986Sk human skin fibroblast cells as well as Ce6 alone. However, the bCDsu-ss-Ce6 nanophotosensitizers showed an improved Ce6 uptake ratio, higher reactive oxygen species (ROS) production, and phototoxicity compared to those of Ce6 alone. GSH addition resulted in a higher Ce6 uptake ratio, ROS generation, and phototoxicity than Ce6 alone, indicating that the bCDsu-ss-Ce6 nanophotosensitizers have a redox-sensitive biological activity in vitro against HeLa human cervical cancer cells. In a tumor xenograft model using HeLa cells, the bCDsu-ss-Ce6 nanophotosensitizers efficiently accumulated in the tumor rather than in normal organs. In other words, the fluorescence intensity in tumor tissues was significantly higher than that of other organs, while Ce6 alone did not specifically target tumor tissue. These results indicated a higher anticancer activity of bCDsu-ss-Ce6 nanophotosensitizers, as demonstrated by their efficient inhibition of the growth of tumors in an in vivo animal tumor xenograft study.

Abstract
The aim of this study is to synthesize phenethyl-conjugated chitosan oligosaccharide (COS) (abbreviated as ChitoPEITC) conjugates and then fabricate chlorin E6 (Ce6)-incorporated nanophotosensitizers for photodynamic therapy (PDT) of HCT-116 colon carcinoma cells. PEITC was conjugated with the amine group of COS. Ce6-incorporated nanophotosensitizers using ChitoPEITC (ChitoPEITC nanophotosensitizers) were fabricated by dialysis method. 1H nuclear magnetic resonance (NMR) spectra showed that specific peaks of COS and PEITC were observed at ChitoPEITC conjugates. Transmission electron microscope (TEM) confirmed that ChitoPEITC nanophotosensitizers have spherical shapes with small hydrodynamic diameters less than 200 nm. The higher PEITC contents in the ChitoPEITC copolymer resulted in a slower release rate of Ce6 from nanophotosensitizers. Furthermore, the higher Ce6 contents resulted in a slower release rate of Ce6. In cell culture study, ChitoPEITC nanophotosensitizers showed low toxicity against normal CCD986Sk human skin fibroblast cells and HCT-116 human colon carcinoma cells in the absence of light irradiation. ChitoPEITC nanophotosensitizers showed a significantly higher Ce6 uptake ratio than that of free Ce6. Under light irradiation, cellular reactive oxygen species (ROS) production of nanophotosensitizers was significantly higher than that of free Ce6. Especially, PEITC and/or ChitoPEITC themselves contributed to the production of cellular ROS regardless of light irradiation. ChitoPEITC nanophotosensitizers showed significantly higher PDT efficacy against HCT-116 cells than that of free Ce6. These results indicate that ChitoPEITC nanophotosensitizers have superior potential in Ce6 uptake, ROS production and PDT efficacy. In the HCT-116 cell-bearing mice tumor-xenograft model, ChitoPEITC nanophotosensitizers efficiently inhibited growth of tumor volume rather than free Ce6. In the animal imaging study, ChitoPEITC nanophotosensitizers were concentrated in the tumor tissue, i.e., fluorescence intensity in the tumor tissue was stronger than that of other tissues. We suggest that ChitoPEITC nanophotosensitizers are a promising candidate for the treatment of human colon cancer cells.

Abstract
Abstract
Inflammatory processes are essential for the repair processes after myocardial infarction. Among inflammatory cells involved in this process, macrophages play a critical role through polarization in pro-inflammatory M1 or reparative M2 subtype. Pioglitazone, known as a treatment drug for diabetes mellitus, is reported to regulate macrophage polarization toward reparative M2 subtype. Poly L-lactic-co-glycolic acid (PLGA) has been widely accepted as the delivery carrier in drug delivery system (DDS).
Here, we aimed to validate the therapeutic effects and investigate the mechanisms of DDS-based treatment using pioglitazone to left ventricular remodeling after myocardial infarction.
Pioglitazone-incorporated PLGA microspheres (PGZ-MS) were prepared and the drug release profile was evaluated. The concentration of interleukin-10 secreted from murine bone marrow derived macrophages incubated with PGZ-MS was quantified in the culture supernatant. To validate the therapeutic potential of PGZ-MS in vivo, Sprague-Dawley rats were subjected to permanent left coronary artery ligation to induce myocardial infarction. Mock-MS (100 μg) or PGZ-MS (100 μg) was injected to the infarct region just after induction (n=9–11/group). Cardiac function and left ventricular size were assessed by echocardiography. At 28-day after surgery, rats were sacrificed, and excised hearts were evaluated histologically.
PGZ-MS released 1.8±0.3% of incorporated PGZ within 24 hours and 29.5±1.2% within 14 days indicating sustained release of PGZ in vitro. PGZ-MS augmented Interleukin-10 release from bone marrow derived macrophages, indicating polarization toward reparative M2 subtype. PGZ-MS significantly ameliorated cardiac function after myocardial infarction (fractional shortening: MI vs MI+Mock-MS vs MI+PGZ-MS, 24.4±1.1 vs 24.3±1.6 vs 32.2±1.4%; P=0.0035) with reverse remodeling (wall thickness: MI vs MI+Mock-MS vs MI+PGZ-MS, 0.69±0.12 vs 0.71±0.13 vs 1.06±0.09; P=0.03). Immunohistochemical analyses revealed that PGZ-MS enhanced macrophage polarization toward reparative M2 subtype (ratio of reparative M2 macrophages: 0.39±0.03 vs 0.42±0.02 vs 0.54±0.02; P=0.0004) and attenuated apoptosis of cardiomyocytes in the ischemic border zone (MI vs MI+Mock-MS vs MI+PGZ-MS, 2.6±0.2 vs 1.9±0.2 vs 1.2±0.2 cells/field; P=0.002).
In the present study, we confirmed that PGZ-MS could realize sustained release of pioglitazone which resulted in sustained effect of macrophage polarization and attenuated left ventricular remodeling accompanied with the amelioration of cardiac dysfunction and cardiomyocytes apoptosis. The strategy of DDS-based macrophage polarization might serve as a promising strategy in cardiac regenerative therapy for ischemic heart disease in the future.

Abstract
Time-resolved triton burnup studies have been carried out to estimate the behavior of alpha particles in DD fusion experimental devices. In those studies, 14 MeV neutrons emitted through DT reactions in DD plasmas should be measured selectively in the backgrounds of DD neutrons and gamma rays. For this purpose, a scintillating-fiber (Sci-Fi) based fast-neutron detector has been adapted because of its advantages such as fast response, design flexibility in detection efficiency by changing the number of Sci-Fi, and discrimination property against 2.4 MeV neutrons produced through DD reactions and gamma rays. However, its length had conventionally been set to around 10 cm without an optimization study of its design parameters to meet the requirements as 14 MeV neutron detector. In the present study, we tested three types of Sci-Fi detectors with three different lengths and compared with the simulated results of energy deposition, through which we tried to understand the phenomena in the detection process of fast neutrons. From the results, it has been shown that, due to the self-shielding of neutrons by Sci-Fi and the attenuation of scintillation photons during the transmission process to the photomultiplier tube, the optimal length of Sci-Fi is concluded to be about 6 cm.

Abstract
Residual stress values in a material are governed by the measurements of the atomic spacings in a specific crystallographic plane and the elastic constant for that plane. It has been reported that the value of the elastic constant depends on microstructure, preferred orientation, plastic deformation and morphology [1], Thus, the theoretical calculation of the elastic constant may deviate from the intrinsic value for a real alloy.

Abstract
In order to evaluate the specificity of tumor markers in chronic renal failure, we have determined serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 19.9 (CA 19.9), carbohydrate antigen 50 (CA 50), alfafetoprotein (AFP), neuron-specific enolase (NSE), prostatic acid phosphatase (PAP), prostatic specific antigen (PSA), squamous cell carcinoma antigen (SCC), carbohydrate antigen 15.3 (CA 15.3) and carbohydrate antigen 125 (CA 125) in 30 patients with cronic renal failure and in 36 hemodialyzed patients without clinical evidence of neoplasia. CEA, CA 50, NSE and SCC frequently show increased serum levels, suggesting a renal metabolism, while others remain, generally, within the normal levels.

Abstract
CYFRA 21–1, CEA, CA 125, SCC and NSE serum levels were determined in 50 healthy subjects and in 189 patients with primary lung cancer (101 with locoregional disease, 68 with recurrence and 20 patients with no evidence of residual disease (NED). Abnormal CYFRA 21–1 serum levels were found in 53.6% (90/168) of the patients with active cancer. Neither healthy subjects nor NED patients had abnormal serum levels. CYFRa 21–1 serum concentrations were significantly higher in patients with active cancer than in healthy subjects or in NED patients (p < 0.0001). CYFRA 21–1 sensitivity was related to tumor histology with abnormal levels in 64.7% of patients with NSCLC and in 30% of patients with SCLC (P <0.0001). In NSCLC, serum CYFRA 21–1 concentrations were also related to histological type, the highest values being found in squamous cell carcinomas and LCLC and the lowest in adenocarcinomas (p < 0.04). There was also a clear relationship between CYFRA 21–1 and tumor extension, with significantly higher values in patients with metastases than in those without metastases (p < 0.0001). Abnormal CEA values were found in 49.1%, CA 125 in 39%, SCC in 27.8% and NSE in 21.3% of the patients with active cancer. With respect to histological type, CYFRA was elevated in 68.3% of squamous cell carcinomas (CEA: 46.7%, SCC: 50%, CA 125:31.7%, NSE: 11.7%), in 54.8% of adenocarcinomas (CEA: 62%, SCC: 26.2%, CA 125: 59.5%, NSE: 9.5%), in 78.6% of LCLC (CEA: 64.3%, SCC: 28.6%, CA 125: 78.6%, NSE: 7.1%) and in 30% of SCLC (CEA: 37.7%, SCC: 3.8%, CA 125:20.8%, NSE: 45.3%). In summary, CYFRA 21–1 is the most sensitive tumor marker in patients with lung cancer, especially in NSCLC patients.

Abstract
Mucin-like Carcinoma-associated Antigen (MCA) has been associated with many breast cancers. The aim of this study was to evaluate MCA in tumor tissue and serum as a potential tumor marker for prognosis and disease monitoring. MCA levels were determined in the tissue of 196 patients with primary breast cancer, 25 with metastatic disease and 25 patients with benign diseases, in pellet and/or cytosol. MCA levels were also determined in the serum of 50 patients with benign diseases, 148 with primary breast cancer (Mo), 150 with metastatic breast cancer (MT), and 200 with no clinical evidence of disease (NED). MCA tissue concentrations in pellet and cytosol were similar: 66.7 + 251 U/mg and 41.1 + 53 U/mg, respectively. No relationship between MCA levels and tumor size or nodal involvement was found. Higher MCA levels were observed in patients with ER + or PgR + tumors than in those with ER- or PgR- tumors (p < 0.01). Patients with MCA pellet concentrations lower than 10 U/mg of protein had shorter disease - free intervals (DFI) than those with higher values (p < 0.05). Abnormally high serum levels of MCA were found in 8% of patients with benign diseases, 4% of NED patients, 22% of Mo patients, and in 76% of MT cases. In primary breast cancer MCA values were related to tumor size and nodal involvement. A trend toward a lower DFI in patients with elevated presurgical MCA levels was observed but was of no statistical significance. These differences became statistically significant when patients were subdivided according to nodal status, with shorter DFI in those without nodal invasion (p < 0.05). In metastatic patients, changes in serum MCA were related to the tumor's response to treatment in 82% of cases. The highest MCA values were found in patients with liver or bone metastasis and the lowest values were found in those with locoregional recurrence. In conclusion, although MCA is not a specific tumor marker, it can be useful as a prognostic factor (tissue and serum) and in monitoring metastatic patients.

Abstract
CA 125 is not a specific tumor marker, and is synthesized by normal and malignant cells of different origin (mainly in tissues derived from the müllerian epithelia) in a similar proportion. Abnormal CA 125 levels may be found in fluids of different origin (ascites, pleura, pericardium, amniotic fluid, cyst fluid, bronchoalveolar fluid, etc.) and in serum from patients with these fluids. Differences in serum CA 125 found in malignant or benign diseases may be related to the number of cells that synthesize the marker, and are highly dependent on the access to serum, where the marker is normally determined. Moreover, CA 125 is a very good tumor marker in ovarian and lung cancer. The sensitivity of CA 125 in ovarian cancer is related to stage (40–95%), histological type (lower levels in mucinous adenocarcinoma), and the marker is useful in the early detection of recurrence (sensitivity 80%) and in therapy monitoring. It's sensitivity in lung cancer is lower than in ovarian cancer, 39% in locoregional malignancies and 69% in metastastatic disease, but clearly related to stage and histology (mainly in adenocarcinomas and large cell lung cancer) and it is useful in prognosis and disease monitoring.

Abstract
Micromagnetic stimulation using small-sized implantable coils has recently been studied. The main advantage of this method is that it can provide sustainable stimulation performance even if a fibrotic encapsulation layer is formed around the implanted coil by inflammation response, because indirectly induced currents are used to induce neural responses. In previous research, we optimized the geometrical and control parameters used in implantable magnetic stimulation. Based on those results, we fabricated the planar coil and studied the LTP effect in the hippocampal slice by two different magnetic stimulation protocols using the quadripulse stimulation (QPS) pattern. We found that direct magnetic stimulation (DMS) induced insignificant LTP effect and priming magnetic stimulation (PMS) occluded LTP effect after tetanic stimulation, when QPS patterned magnetic stimulation with 1 A current pulse was applied to the planar coil.

Abstract
BACKGROUND Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (DLBCL) of the elderly is defined only in adults older than 50 years. However, EBV-positive DLBCL can affect younger patients. We investigated the prevalence, clinical characteristics and survival outcomes of EBV-positive DLBCL in young adults. PATIENTS AND METHODS We analyzed patients with de novo DLBCL who were registered in the Samsung Medical Center (SMC) retrospective lymphoma cohort and prospective SMC Lymphoma Cohort Study I (ClinicalTrials.gov: NCT00822731). RESULTS A total of 571 cases were included in the analysis. The prevalence of EBV positivity was 6.7% (13/195) and 9.3% (35/376) in the young group (≤50 years) and in the elderly group (>50 years), respectively. EBV status was closely associated with unique unfavorable clinical characteristics [older age, more advanced stage, two or more sites of extranodal involvement, higher International Prognostic Index (IPI), and age-adjusted IPI risk] only in the elderly group. Poor prognostic impact of EBV positivity on overall survival was observed only in the elderly group [hazard ratio (HR) 2.86; 95% confidence interval (CI) 1.83-4.47; P < 0.001], but not in the young group (HR 1.17; 95% CI 0.35-3.89; P = 0.801). CONCLUSION A substantial proportion of EBV-positive DLBCL of the elderly can occur in young adults. EBV positivity of DLBCL in young adults was not associated with unfavorable clinical characteristics or worse outcomes. We suggest that EBV-positive DLBCL should not be confined only in the elderly and 'EBV-positive DLBCL in young adults' needs to be considered as a clinically distinct disease entity. ClinicalTrials.gov: NCT02060435.

Abstract
Background: This prospective, phase II trial evaluated the efficacy and safety of dovitinib in patients with metastatic and/or unresectable gastrointestinal stromal tumours (GISTs) after failure of at least imatinib and sunitinib. Methods: Patients received oral dovitinib, 500 mg once daily, for 5 consecutive days, followed by a 2-day rest, every 28 days. The primary endpoint was disease control rate (DCR; objective response+stable disease (SD)) at 24 weeks, assessed by computed tomography (CT) scan according to RECIST v1.0. Metabolic response was evaluated by positron emission tomography (PET)–CT scans performed at baseline and after 4 weeks of treatment. Results: Between September 2011 and April 2012, 30 patients were enroled. DCR at 24 weeks by RECIST v1.0 was 13% and one patient (3%) had a partial response. Based on the European Organization for Research and Treatment of Cancer PET response criteria, four patients (13%) had a metabolic partial response after 4 weeks of treatment. At a median follow-up of 8.3 months (range, 6.3–12.2 months), median progression-free survival (PFS) was 3.6 months (95% confidence interval (CI), 3.5–3.7 months) and median overall survival was 9.7 months (95% CI, 6.0–13.4 months). Metabolic progressive disease at Week 4 was significantly associated with shorter PFS (P=0.03). Grade 3/4 adverse events included asthenia (20%), neutropenia (13%), thrombocytopenia (10%), and hypertriglyceridaemia (10%). Most toxicities were manageable by dose modification. Conclusion: Dovitinib showed modest antitumour activity with manageable toxicities in heavily pretreated patients with advanced GISTs.

Abstract
BACKGROUND We compared late thoracic radiotherapy (TRT) with early TRT in the treatment of limited-disease small-cell lung cancer (LD-SCLC). PATIENTS AND METHODS Patients with LD-SCLC received four cycles of etoposide plus cisplatin every 21 days. Patients were randomly assigned to receive either TRT administered concurrently with the first cycle (early TRT) or the third cycle (late TRT) of chemotherapy. The primary end point was complete response rate. RESULTS Two hundred twenty-two patients were randomly assigned.Late TRT was not inferior to early TRT in terms of the complete response rate (early v late; 36.0% v 38.0%). Other efficacy measures including overall survival [median, 24.1 v 26.8 months;hazard ratio (HR) 0.93; 95% CI = 0.67–1.29] and progression free survival (median, 12.4 v 11.2 months; HR 1.09; 95%CI = 0.80–1.48) were not different between two arms. No statistical difference was noted in the pattern of treatment failures.However, neutropenic fever occurred more commonly in the early TRT arm than the late TRT arm (21.6% v 10.2%; P = 0.02) [corrected]. CONCLUSION In LD-SCLC treatment, TRT starting in the third cycle of chemotherapy seemed to be noninferior to early TRT, and had a more favorable profile with regard to neutropenic fever.

Abstract
BACKGROUND Given the more comorbidities with a decline in physiologic reserve, it can be challenging to make appropriate treatment decisions in the elderly. PATIENTS AND METHODS Here, we prospectively evaluated and compared the health-related quality of life (HRQOL) of patients aged ≥ 65 with aged <65 who were treated with a postoperative chemotherapy for completely resected stage Ib, II or IIIa non-small-cell lung cancer (NSCLC). Either four cycles of paclitaxel (Taxol)-carboplatin (PC) or vinorelbine-cisplatin (NP) was used. The HRQOL was assessed with EORTC QLQ-C30 and EORTC QLQ-LC13. RESULTS Between October 2008 and October 2011, a total of 139 patients (aged <65, n = 73; ≥ 65, n = 66) were enrolled, and 127 (91.4%) completed the questionnaire. Overall, the quality of life (QOL) in elderly patients did not significantly deteriorate with adjuvant chemotherapy and the time trend of QOL in elderly patients was similar to that of younger patients. Although the elderly suffered from increased treatment-related adverse events involving sore mouth, peripheral neuropathy and alopecia compared with the baseline, the same time trends were also observed in younger group. The mean dose intensities (MDIs) for PC and NP regimen were not significantly different between the two age groups. CONCLUSIONS Postoperative chemotherapy did not substantially reduce HRQOL in elderly NSCLC patients, and HRQOL during and after adjuvant chemotherapy did not significantly differ by age.

Abstract
Using a Volterra-Wiener model and the Laguerre expansion technique, we estimated in a previous study the parameters that characterize linear and the second order effects of respiration ("RSA") and arterial blood pressure ("ABR") on heart rate. RSA and ABR gains were significantly lower in Obstructive Sleep Apnea (OSA) patients than in normal subjects. During sleep, ABR gain increased in normals but remained unchanged in OSA. In the present work, we investigated the physiological interpretation of the nonlinear components of the described model of heart rate variability, by means of simulation on the computed linear and nonlinear kernels. Our results indicate that the 2<sup>nd</sup>order kernels reflect specific characteristics of the RSA and ABR mechanisms, such as a RSA frequency response dependence upon tidal volume, saturation in the ABR-Blood Pressure relation, and respiratory modulation of ABR.

Abstract
This prospective study explored the relationship between expression of AKR1B10 mRNA and various clinical parameters in non-small-cell lung cancer (NSCLC) in terms of its validation as a marker for NSCLC. Tumour tissue samples were collected from 229 patients with NSCLC. Tissue samples from adjacent non-malignant lung tissue (> 5 cm from the tumour) of 89 of these patients and samples from 20 patients with benign lung disease were used as controls. Quantitative reverse transcription- polymerase chain reaction showed significantly higher levels of AKR1B10 mRNA expression in NSCLC tumour tissue than in adjacent non-malignant lung tissue and benign lung tissue. Statistically significant factors for AKR1B10 mRNA over-expression were found to be male gender, smoking, squamous cell carcinoma and moderate or poor cell differentiation. It is concluded that AKR1B10 seems to have potential as a prognostic marker for NSCLC and warrants further investigation.
