Abstract
In advanced or relapsed pancreatic cancer, mono- or duo-therapy has shown modest efficacy at best. The present study evaluated the efficacy of a triplet combination in relapsed or advanced pancreatic cancer. A total of 37 patients with adenocarcinoma of the pancreas in stage III/IV or with relapsed disease were treated with a gemcitabine, 5-fluorouracil and cisplatin (GFP) regimen every 3 weeks. Only 29 out of 37 patients were evaluable for response due to early treatment interruption in 8 patients. The overall response rate was 24.1% and the disease control rate was 68.9%. The progression-free survival (PFS) rate was 61.5, 30.9 and 17.6% at 3, 6 and 9 months, respectively, and the overall survival (OS) rate was 46.5 and 30.6% at 6 and 12 months, respectively. Grade 3/4 leukopenia, neutropenia and thrombocytopenia occurred in 18.4, 29.9 and 24.5% of 147 cycles, respectively. Old age and a poor performance status (PS) were associated with the early discontinuation of chemotherapy (P=0.038 and P=0.036, respectively). In patients <65 years old and with a PS of <2, the median PFS and OS times were 5.3 months and 10.3 months, respectively. Overall, although GFP resulted in acceptable response and survival rates, it does not appear to have marked superiority to gemcitabine-based single or duplet chemotherapy.

Abstract
Search results for nucleon decays p→e^{+}X, p→μ^{+}X, n→νγ (where X is an invisible, massless particle) as well as dinucleon decays np→e^{+}ν, np→μ^{+}ν, and np→τ^{+}ν in the Super-Kamiokande experiment are presented. Using single-ring data from an exposure of 273.4 kton·yr, a search for these decays yields a result consistent with no signal. Accordingly, lower limits on the partial lifetimes of τ_{p→e^{+}X}>7.9×10^{32} yr, τ_{p→μ^{+}X}>4.1×10^{32} yr, τ_{n→νγ}>5.5×10^{32} yr, τ_{np→e^{+}ν}>2.6×10^{32} yr, τ_{np→μ^{+}ν}>2.2×10^{32} yr, and τ_{np→τ^{+}ν}>2.9×10^{31} yr at a 90% confidence level are obtained. Some of these searches are novel.

Abstract
Super-Kamiokande (SK) can search for weakly interacting massive particles (WIMPs) by detecting neutrinos produced from WIMP annihilations occurring inside the Sun. In this analysis, we include neutrino events with interaction vertices in the detector in addition to upward-going muons produced in the surrounding rock. Compared to the previous result, which used the upward-going muons only, the signal acceptances for light (few-GeV/c^{2}-200-GeV/c^{2}) WIMPs are significantly increased. We fit 3903 days of SK data to search for the contribution of neutrinos from WIMP annihilation in the Sun. We found no significant excess over expected atmospheric-neutrino background and the result is interpreted in terms of upper limits on WIMP-nucleon elastic scattering cross sections under different assumptions about the annihilation channel. We set the current best limits on the spin-dependent WIMP-proton cross section for WIMP masses below 200 GeV/c^{2} (at 10 GeV/c^{2}, 1.49×10^{-39} cm^{2} for χχ→bb[over ¯] and 1.31×10^{-40} cm^{2} for χχ→τ^{+}τ^{-} annihilation channels), also ruling out some fraction of WIMP candidates with spin-independent coupling in the few-GeV/c^{2} mass range.

Abstract
White organic light-emitting devices (WOLEDs) were fabricated utilizing blue and red emitting organic light-emitting devices and a color conversion layer (CCL) made of yttrium aluminum garnet (YAG:Ce3+) phosphors embedded into polymethylmethacrylate. The good color balance for the color conversion of the WOLEDs was achieved utilizing 20-nm blue and 10-nm red OLEDs. The electroluminescence spectrum for the fabricated device showed a white color consisting of the blue color from the 4,4-bis(2,2-diphenylethen-1-yl)bipheny layer, the red color from the tris-(8-hydroxyquinolinato) aluminum: 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran layer, and the green color from the YAG:Ce3+ phosphor. The Commission Internationale de l'Eclairage coordinates of the WOLEDs slightly shifted from (0.25, 0.23) of the blue and red emission OLEDs without phosphors to (0.34, 0.35) of the OLEDs with green phosphors, indicative of the pure white color. WOLEDs with a CCL exhibited three wavelength white emissions with a color rendering index of 86.

Abstract
The trilepton nucleon decay modes p→e+νν and p→μ+νν violate |Δ(B-L)| by two units. Using data from a 273.4 kt yr exposure of Super-Kamiokande a search for these decays yields a fit consistent with no signal. Accordingly, lower limits on the partial lifetimes of τp→e+νν>1.7×10(32) years and τp→μ+νν>2.2×10(32) years at a 90% confidence level are obtained. These limits can constrain Grand Unified Theories which allow for such processes.

Abstract
We report in situ transmission electron microscopy studies of the formation of ZnO nanostructures--nanoscale depressions, nanoholes, nanoribbons, and nanosheets--and the phase stability and kinetics of Au catalysts on ZnO. During annealing, the ZnO layer produces hexagonally shaped, vertical nanoscale depressions, which increase in size along the 〈 0001 〉 growth direction through preferential dissociation from the {101[combining macron]0} facet and which subsequently form hexagonal islands at their six-fold junctions. Real time observations of the annealing of Au deposited on ZnO show that the catalysts remain solid up to 900 °C, an observation that has implications regarding ZnO nanowire growth via the vapor-solid-solid mechanism (VSS). The Au also creates hexagonal nanoscale holes only at the location of solid Au catalysts, via the solid-solid-vapor (SSV) mechanism. Importantly, coarsening of the Au particles is negligible due to limited Au diffusion on the side facets of the nanoscale depressions, suggesting an approach to the growth of uniform hybrid nanowires with control over both diameter and location. Furthermore, we directly monitor the evolution of the transformation of a nanoribbon into a nanosheet with {101[combining macron]0} facets. This process takes place through a periodic, kinetic roughening transition of the surface, which is controlled by the kinetic competition between surface growth and the transfer of evaporated gases. In total, these observations give new insights into multiple growth processes occurring in this important materials system.

A search for the dinucleon decay pp → K+ K+ has been performed using 91.6 kton·yr data from Super-Kamiokande-I. This decay provides a sensitive probe of the R-parity-violating parameter λ112''. A boosted decision tree analysis found no signal candidates in the data. The expected background was 0.28±0.19 atmospheric neutrino induced events and the estimated signal detection efficiency was 12.6%±3.2%. A lower limit of 1.7×10(32) years has been placed on the partial lifetime of the decay O16 → C14K+ K+ at 90% C.L. A corresponding upper limit of 7.8×10(-9) has been placed on the parameter λ112''.

Abstract
We report an indication that the elastic scattering rate of solar B8 neutrinos with electrons in the Super-Kamiokande detector is larger when the neutrinos pass through Earth during nighttime. We determine the day-night asymmetry, defined as the difference of the average day rate and average night rate divided by the average of those two rates, to be [-3.2 ± 1.1(stat) ± 0.5(syst)]%, which deviates from zero by 2.7 σ. Since the elastic scattering process is mostly sensitive to electron-flavored solar neutrinos, a nonzero day-night asymmetry implies that the flavor oscillations of solar neutrinos are affected by the presence of matter within the neutrinos' flight path. Super-Kamiokande's day-night asymmetry is consistent with neutrino oscillations for 4 × 10(-5) eV(2) ≤ Δm 2(21) ≤ 7 × 10(-5) eV(2) and large mixing values of θ12, at the 68% C.L.

Abstract
BACKGROUND AND AIM Eating slowly is a crucial concept in behavioural nutrition and is recommended for weight management as it is believed to have an important effect on satiety control. This study aimed to determine whether or not eating rate is associated with cardiometabolic risk factors. METHODS AND RESULTS This was a cross-sectional study involving 8775 Korean adults, who visited the Center for Health Promotion of Korea University Anam Hospital in Seoul, Korea. In male study participants, weight and body mass index (BMI) were found to depend on eating rate after adjusting for age, alcohol consumption, smoking, exercise and total energy intake. When adjusted for age, alcohol consumption, smoking, exercise and BMI, differences were found between the eating rate groups with respect to high-density lipoprotein (HDL)-cholesterol, alanine aminotransferase (ALT) and alkaline phosphatase (ALP) values, white blood cell (WBC) count and total energy intake. Female participants were found to be different from males in that diastolic blood pressure and low-density lipoprotein (LDL)- and HDL-cholesterol values were significantly different between each eating rate group, while ALT and ALP values, WBC count and total energy intake were not. Compared with the slow eating rate group (>15 min), the fastest eating rate group (<5 min) had significantly increased odds ratios for cardiometabolic risk factors such as high glucose and low HDL-cholesterol levels in males, even after adjusting for BMI. CONCLUSION Fast eating rates are associated with obesity and other cardiometabolic risk factors, particularly in men. Thus, eating slowly is recommended for weight reduction and to decrease cardiovascular risk factors.

Abstract
9633 Background: Combination of aprepitant, 5-HT3 receptor antagonist and steroid improve complete response (CR) of chemotherapy induced nausea and vomiting (CINV). But until now, there was no information whether ramosetron is as effective as other 5-HT3receptor antagonists for the combination regimen. Therefore, we compared a ramosetron, aprepitant and dexamethasone (RAD) with ondansetron, aprepitant and dexamethasone (OAD) to establish the non-inferiority of RAD in controlling highly emetogenic chemotherapy induced nausea and vomiting. Methods: A total of 334 patients with malignant disease who were scheduled to receive highly emetogenic chemotherapy were randomized to RAD or OAD. Aprepitant (125 mg day 1; 80 mg day 2, 3) and dexamethasone (12 mg day 1; 8 mg day 2-4) were administered to both group. Intravenous ramosetron (0.3mg day 1) or ondansetron (16mg day1) was given to RAD or OAD, respectively. Patients recorded vomiting and nausea (VAS score) on the diary. The primary end point was CR (no vomiting or retching and no rescue medication) rate in the acute period (chemotherapy day 1). The non-inferiority margin was defined as -15% differences. Results: 299 patients (RAD 143, OAD 156) were eligible for the efficacy analyses of modified intention-to-treat. Median age and sex were 60 (IQR 52 – 66) and 61 (51.5 – 68, p=0.54), 90 Male/66 Female and 114 Male/29 Female (p<0.0001) in RAD and OAD, respectively. There were no significant differences between two groups on the other baseline characteristics. The CR rates of RAD vs OAD were 84.6% vs 77.6% (95% C.I. -0.4 – 14.5%) at acute period, 69.5% vs 62.6% (-2.1 – 16.0%) at delayed period (days 2-5), and 66.7% vs 58.1% (-0.6 – 17.8%) at overall period. Median nausea score at acute period were 4 (IQR 2 – 5) and 3 (2-5, p=0.14) in RAD and OAD, respectively. There were no grade 3 or 4 toxicities. Conclusions: RAD regimen is as effective and tolerable as OAD antiemetic combination for the prevention of CINV in patients receiving highly emetogenic chemotherapy. Ramosetron could be considered as one of the best partners for aprepitant. Clinical trial information: NCT01536691.

Abstract
Super-Kamiokande atmospheric neutrino data were fit with an unbinned maximum likelihood method to search for the appearance of tau leptons resulting from the interactions of oscillation-generated tau neutrinos in the detector. Relative to the expectation of unity, the tau normalization is found to be 1.42 ± 0.35(stat)(-0.12)(+0.14)(syst) excluding the no-tau-appearance hypothesis, for which the normalization would be zero, at the 3.8σ level. We estimate that 180.1 ± 44.3(stat)(-15.2)(+17.8) (syst) tau leptons were produced in the 22.5 kton fiducial volume of the detector by tau neutrinos during the 2806 day running period. In future analyses, this large sample of selected tau events will allow the study of charged current tau neutrino interaction physics with oscillation produced tau neutrinos.

Abstract
BACKGROUND Gemcitabine has been recognized as a standard chemotherapy in advanced pancreas cancer(APC). We conducted a phase II study of a triple combination regimen (GPT) consisting of gemcitabine (G), cisplatin(P) and erlotinib (T) in patients with APC. PATIENTS AND METHODS Chemotherapy-naïve patients with locally advanced or metastatic, histologically confirmed adenocarcinoma of the pancreas were treated with erlotinib 100 mg daily, 1,000 mg/m2 of gemcitabine and 25 mg/m2 of cisplatin administered on days 1 and 8, respectively, every 3 weeks.The primary end point was objective response. Secondary end points included progression-free survival, overall survival and toxicity. The study was designed according to the optimal two-stage design. RESULTS Twenty-two patients were enrolled between June 2009 and August 2010. No complete response was achieved and partial response was observed in 5 patients (26%), Stable disease in 7 (37%), and progressive disease in 7 (37%). The median time to progression was 4.0 months (95% CI: 2.9–5.1 months), and the median overall survival 6.8 months (95% CI: 3.7–9.9 months). The response rate in stage I reached the target (≥3/22,p0010%) established for movement to stage II but this study was determined to close earlier than planned because of unexpected treatment-related deaths (3 patients). CONCLUSION The triple regimen of GPT is effective for APC. Treatment related mortalities factored early closure of this GPT protocol. Considering effect and toxicity, this triple regimen seems to offer few benefits to the patients compared with gemcitabine based doublets. (ClinicalTrials.gov number, NCT00922896).

Outcomes of third-line docetaxel-based chemotherapy in advanced gastric cancer who failed previous oxaliplatin-based and irinotecan-based chemotherapies. Cancer Res Treat 2012; 44:235-41.

Abstract
Purpose Little is known about outcomes in the use of third-line chemotherapy in cases of advanced gastric cancer (AGC). The primary aim of this retrospective study was to evaluate outcomes of docetaxel-based chemotherapy in patients with AGC that progressed after both oxaliplatin-based and irinotecan-based regimens. Materials and Methods Eligible patients were those with AGC who had previous chemotherapy including fluoropyrimidine and oxaliplatin as well as fluoropyrimidine and irinotecan and who received subsequent docetaxel-based chemotherapy. Thirty-five patients were retrospectively recruited from 5 medical centers in Korea. Patients received either weekly or 3 weekly with docetaxel +/- cisplatin. Results Thirty-one out of 35 patients were evaluated for treatment response. A total of 94 cycles of chemotherapy (median, 2; range, 1 to 7) were administered. The overall response rate was 14.3%, and the disease control rate was 45.7%. The median progression-free survival (PFS) was 1.9 months (95% confidence interval [CI], 1.1 to 2.7 months). The median overall survival (OS) was 3.6 months (95% CI, 2.8 to 4.4 months). PFS and OS were significantly prolonged in patients of the Eastern Cooperative Oncology Group, with performance status of 0 or 1 in multivariate analysis (PFS: hazard ratio[HR], 0.411; 95% CI, 0.195 to 0.868; p=0.020 and OS: HR, 0.390; 95% CI, 0.184 to 0.826; p=0.014, respectively). Four of the 35 patients enrolled in the study died due to infection associated with neutropenia. Conclusion Our findings suggest that salvage docetaxel-based chemotherapy is a feasible treatment option for AGC patients with good performance status (PS), whereas chemotherapy for patients with poor PS (PS≤2) should be undertaken with caution for those who previously failed oxaliplatin- and irinotecan-based regimens.

Abstract
BACKGROUND The objective of this study was to identify prognostic factors for survival in patients with primary diffuse large B-cell lymphoma (DLBCL) of the adrenal gland. METHODS Thirty one patients diagnosed with primary adrenal DLBCL from 14 Korean institutions and treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) were analyzed. RESULTS Complete remission (CR) and overall response rate after R-CHOP chemotherapy were 54.8% and 87.0%. The 2-year estimates of overall survival (OS) and progression-free survival (PFS) were 68.3% and 51.1%. In patients achieving CR, significant prolongations of OS (P = 0.029) and PFS (P = 0.005) were observed. Ann Arbor stage had no influence on OS. There was no significant difference in OS between patients with unilateral involvement of adrenal gland and those with bilateral involvement. When staging was modified to include bilateral adrenal involvement as one extranodal site, early stage (I or II) significantly correlated with longer OS (P = 0.021) and PFS (P <0.001). CONCLUSIONS Contrary to prior reports, our data suggests that outcomes of primary adrenal DLBCL are encouraging using a regimen of R-CHOP, and that achieving CR after R-CHOP is predictive of survival. Likewise, our modified staging system may have prognostic value.

Abstract
The RENO experiment has observed the disappearance of reactor electron antineutrinos, consistent with neutrino oscillations, with a significance of 4.9 standard deviations. Antineutrinos from six 2.8 GW(th) reactors at the Yonggwang Nuclear Power Plant in Korea, are detected by two identical detectors located at 294 and 1383 m, respectively, from the reactor array center. In the 229 d data-taking period between 11 August 2011 and 26 March 2012, the far (near) detector observed 17102 (154088) electron antineutrino candidate events with a background fraction of 5.5% (2.7%). The ratio of observed to expected numbers of antineutrinos in the far detector is 0.920±0.009(stat)±0.014(syst). From this deficit, we determine sin(2)2θ(13)=0.113±0.013(stat)±0.019(syst) based on a rate-only analysis.

Abstract
We present a search for differences in the oscillations of antineutrinos and neutrinos in the Super-Kamiokande-I, -II, and -III atmospheric neutrino sample. Under a two-flavor disappearance model with separate mixing parameters between neutrinos and antineutrinos, we find no evidence for a difference in oscillation parameters. Best-fit antineutrino mixing is found to be at (Δm2,sin2 2θ)=(2.0×10(-3) eV2, 1.0) and is consistent with the overall Super-K measurement.

Abstract
This study aimed to evaluate the long-term efficacy of entecavir (ETV) in adefovir (ADV)-refractory chronic hepatitis B (CHB) patients with prior lamivudine (LMV) resistance. A total of 55 ADV-refractory CHB patients with prior LMV resistance, who received rescue therapy with ETV 1 mg daily for at least 12 months, were consecutively enrolled and analysed. Forty-four patients were men, and their median age was 47 (25-69). Ten patients had liver cirrhosis and 46 patients were positive for hepatitis B e antigen (HBeAg). Median hepatitis B virus DNA levels were 6.6 (4.3-8.0) log(10) copies/mL, and the median duration of ETV therapy was 24 (12-47) months. Cumulative virologic response rates at 6, 12, 24 and 36 months were 18%, 29%, 58% and 75%, respectively. HBeAg loss occurred in 10 (21.7%) of 46 HBeAg-positive patients. In multivariate analysis, only initial virologic response at 3 months remained as an independent predictor for virologic response (RR 3.143; 95% CI 1.387-7.120; P = 0.006). The patients with a virological response at 3 months had not only a significantly higher probability of achieving a virologic response (P < 0.001) but also lower probability of experiencing a virologic breakthrough (P = 0.043) than the patients without an early response. Viral breakthrough was observed in 29 patients during the follow-up period. Cumulative breakthrough rates at 6, 12, 24 and 36 months were 0%, 15%, 45% and 73%, respectively. ETV monotherapy may be considerably efficacious in cases with an initial virological response but its efficacy is attenuated by frequent emergence of ETV resistance in ADV-refractory CHB patients with prior LMV resistance.

Abstract
Previous linkage analysis of an Asian population proposed possible candidate genes for mandibular prognathism, such as Matrilin-1 (cartilage matrix protein). To investigate the association between the single-nucleotide polymorphisms (SNPs) in Matrilin-1 and mandibular prognathism, we investigated three sequence variants (-158 T>C, 7987 G>A, 8572 C>T) in 164 mandibular prognathism patients and 132 control individuals with a normal occlusion. The results showed that the 8572 TT genotypes in Matrilin-1 showed increased risk of mandibular prognathism (OR = 9.28, 95% Cl = 1.19~197.57, P < 0.05), whereas the 7987 AA genotype showed a protective effect for mandibular prognathism (OR = 0.16, 95% Cl = 0.05~0.47, P < 0.05). Genotyping results showed that the Matrilin-1 polymorphism haplotype TGC (ht4; 158T, 7987G, and 8572C alleles) had a pronounced risk effect for mandibular prognathism compared with controls (OR = 5.16, 95% Cl = 2.03~13.93, P < 0.01). The results suggest that polymorphisms in Matrilin-1 could be used as a marker for genetic susceptibility to mandibular prognathism.
