Abstract
OBJECTIVE Hepatic ischemia-reperfusion injury (IRI) is considered a major cause of hepatic damage in liver surgery. The aim of this study was to investigate the effect of the remote ischemic perconditioning method on hepatic IRI in a rat model. METHODS Seventeen rats underwent hepatic IRI for 30 minutes followed by reperfusion, and were divided into 3 groups: group I, only hepatic IRI (n = 5); group II, hepatic IRI with remote perconditioning (n = 7); and group III, hepatic IRI with remote postconditioning (n = 5). RESULTS For Bax/β-actin, mean values of the 3 groups (±standard deviation) were 1.29 ± 0.26 (group I), 0.89 ± 0.15 (group II), and 1.02 ± 0.23 (group III). The level of Bax/β-actin in group II was significantly lower than in group I (P < .01). The cleaved Caspase-3/β-actin ratio for groups I, II, and III was 0.93 ± 0.22, 0.46 ± 0.16, and 0.63 ± 0.22, respectively. The level of cleaved Caspase-3/β-actin in groups II and III were significantly lower than in group I (P < .01 and P < .05, respectively). The Bcl-2/β-actin ratio for groups I, II, and III was 1.01 ± 0.09, 1.19 ± 0.39, and 1.20 ± 0.12, respectively. However, there were no significant difference between groups II and III and group I. CONCLUSIONS The remote perconditioning on rat hepatic IRI downregulated the Bax and cleaved Caspase-3 expression.

Abstract
Many epidemiological studies suggest that overweight is associated with an elevated risk of psychiatric disorders and suicidal tendency. However, findings vary across studies, and some have contradictory results. We investigated the relationship of overweight with a range of psychiatric disorders and suicidality in the Korean general population. A multistage cluster sampling design was adopted. A total of 6,022 participants aged 18-74 years completed face-to-face interviews (response rate: 78.7%) including assessment of psychiatric disorders, suicidality, and height and weight. Overweight (defined as body mass index of ≥ 25) was associated with an increase in the lifetime prevalence of depressive disorders (adjusted odds ratio [AOR] 1.38; 95% confidence interval [CI], 1.07-1.77), suicidal ideation (AOR, 1.42; 95% CI, 1.20-1.68), and suicidal plans (AOR, 1.44; 95% CI, 1.02-2.03), controlling for sociodemographic variables. Subgroup analysis found that the association between overweight and depressive disorders exists only in women aged 18-44 years (AOR, 1.75; 95% CI, 1.07-2.89) while the association of overweight with suicidal ideation (AOR, 2.08; 95% CI, 1.53-2.82) and suicide plans (AOR, 2.59; 95% CI, 1.25-5.37) existed only in men aged 18-44 years. Overweight was associated with increased odds of nicotine use disorders in women aged 18-44 years (AOR, 2.35; 95% CI, 1.02-5.43), but the association was in the opposite direction in men aged 45-74 years (AOR, 0.64; 95% CI, 0.43-0.94). In conclusion, overweight is related to various psychiatric disorders and suicidality in Korea. Policy makers and clinicians should pay more attention to the mental health of overweight individuals.

Abstract
BACKGROUND De novo malignancy is not uncommon after liver transplantation (LT). Gastric cancer is one of the most common malignancies in both the Korean general population and LT recipients, and colorectal cancer prevalence is gradually increasing. METHODS Among 3690 adult recipients who underwent LT from January 1999 and December 2013, the screening patterns and prognosis of 26 cases of gastric cancer and 22 cases of colorectal cancer were analyzed. RESULTS For gastric cancer, the mean patient age was 54.6 ± 6.2 years at LT and 59.5 ± 6.7 years at cancer diagnosis, with a post-transplant interval of 60.2 ± 29.8 months. Patients were divided into regular (n = 18) and non-regular (n = 8) screening groups, with early cancer found in 14 and 0 patients; their 2-year survival rates after cancer diagnosis were 93.1% and 33.3% (P = .006), respectively. Endoscopic resection was successfully performed in 8 patients, all in the regular screening group. For colorectal cancer, the mean patient age was 53.3 ± 6.1 years at LT and 58.1 ± 6.7 years at cancer diagnosis, with a post-transplant interval of 54.3 ± 38.0 months. Patients were divided into regular (n = 19) and non-regular (n = 3) screening groups, with early cancer found in 12 and 0 patients; their 2-year survival rates after cancer diagnosis of 92.3% and 33.3% (P = .003), respectively. Endoscopic resection was successfully performed in 6 patients, all in the regular screening group. CONCLUSIONS LT recipients are strongly advised to undergo regular screening studies for various de novo malignancies, especially cancers common in the general population. Regular endoscopic screening contributes to the timely detection of gastric and colorectal cancers, improving post-treatment survival outcomes.

Abstract
BACKGROUND Basal cell carcinoma (BCC) is by far the most common cancer in white populations. In addition, recent reports have demonstrated an increasing incidence of BCC in Korea. We have observed a significant number of early-onset BCC cases in which the disease occurred in patients younger than 50 years. OBJECTIVE To investigate the clinicopathological characteristics of early-onset BCC in an Asian population, specifically in Koreans. METHODS One hundred and five patients with early-onset BCC were enrolled from a total of 1047 BCC patients who underwent surgery between January 1997 and December 2014 (942 patients over the age of 50 years were designated as the control group). RESULTS Early-onset BCC accounted for 10.03% of all 1047 cases and the incidence over time displayed an incremental trend. The early-onset group displayed similar results as the control group, with a predominance of female BCC patients and the majority of tumours displaying the following characteristics: small in size, occurring in sun-exposed areas and belonging to the noduloulcerative clinical subtype and nodular histopathological subtype. In comparison with a previous study in a Western population, the incidence of the disease in non-exposed areas of the body, as well as the proportion of tumours of the superficial histological subtype, were lower in Asian patients. CONCLUSION Although the clinicopathological characteristics of BCC are well-known, these characteristics have not been determined for early-onset BCC in an Asian population. Therefore, this study is the first report on early-onset BCC in Asians, specifically in a Korean patient group.

Abstract
CCR3 is a chemokine receptor that mediates the accumulation of allergic inflammatory cells, including eosinophils and Th2 cells, at inflamed sites. The regulatory sequence of the CCR3 gene, contains two Runt-related transcription factor (RUNX) 1 sites and two PU.1 sites, in addition to a functional GATA site for transactivation of the CCR3 gene. In the present study, we examined the effects of the cis-acting elements of RUNX1 and PU.1 on transcription of the gene in EoL-1 eosinophilic cells and Jurkat T cells, both of which expressed functional surface CCR3 and these two transcription factors. Introduction of RUNX1 siRNA or PU.1 siRNA resulted in a modest decrease in CCR3 reporter activity in both cell types, compared with transfection of GATA-1 siRNA. Cotransfection of the two siRNAs led to inhibition in an additive manner. EMSA analysis showed that RUNX1, in particular, bound to its binding motifs. Mutagenesis analysis revealed that all point mutants lacking RUNX1- and PU.1-binding sites exhibited reduced reporter activities. These results suggest that RUNX1 and PU.1 participate in transcriptional regulation of the CCR3 gene.

Abstract
BACKGROUND The mechanism of podocyte injury observed with the use of rapamycin (RPM) remains unclear. The conversion from calcineurin inhibitors (CNIs) to RPM in kidney transplant recipients has been associated with a higher incidence of proteinuria and renal injury. In this study, we performed proteomic analyses to investigate the alteration of protein expression in mouse podocytes treated with RPM in comparison with CNI/RPM combination. METHODS Immortalized mouse podocytes were treated with 20 nmol/L RPM or 20 nmol/L RPM + 1 μg/mL cyclosporine. Podocyte proteins were separated by 2-dimensional polyacrylamide gel electrophoresis (2DE) and identified by matrix-assisted laser desorption time-of-flight (MALDI-TOF) mass spectrometry and peptide fingerprinting. Selected proteins were analyzed by means of Western blot assay. RESULTS We identified 36 differently expressed proteins after isolated RPM or CNI/RPM combination treatment in cultured mouse podocytes. There are 3 distinct patterns of protein expression: (1) potentiated down- or upregulation of proteins by CNI/RPM treatment compared with isolated RPM treatment (n = 4); (2) partial offset of down-regulation by CNI/RPM in comparison with RPM treatment (n = 25); (3) no difference in down-regulation between RPM and CNI/RPM treatment (n = 5). We found a significant interplay between RPM and CNI on the expression of the selected proteins in mouse podocytes. This might explain the higher incidence of proteinuria by CNI/RPM combination in clinical settings. CONCLUSIONS Further study is required to elucidate the target protein associated with RPM-induced podocyte injury.

Abstract
Type I interferon (IFN-I) plays a critical role in antiviral and antitumor defense. In our previous studies, we showed that IFN-I-inducible 2'-5' oligoadenylate synthetase-like 1 (OASL1) negatively regulates IFN-I production upon viral infection by specifically inhibiting translation of the IFN-I-regulating master transcription factor, interferon regulatory factor 7 (IRF7). In this study, we investigated whether OASL1 plays a negative role in the anti-tumor immune response by using OASL1-deficient (Oasl1 (-/-)) mice and transplantable syngeneic tumor cell models. We found that Oasl1 (-/-) mice demonstrate enhanced resistance to lung metastatic tumors and subcutaneously implanted tumors compared to wild-type (WT) mice. Additionally, we found that cytotoxic effector cells such as CD8(+) T cells (including tumor antigen-specific CD8(+) T cells) and NK cells as well as CD8α(+) DCs (the major antigen cross-presenting cells) were much more frequent (>fivefold) in the Oasl1 (-/-) mouse tumors. Furthermore, the cytotoxic effector cells in Oasl1 (-/-) mouse tumors seemed to be more functionally active. However, the proportion of immunosuppressive myeloid-derived suppressor cells within hematopoietic cells and of regulatory T cells within CD4(+) T cells in Oasl1 (-/-) mouse tumors did not differ significantly from that of WT mice. Tumor-challenged Oasl1 (-/-) mice expressed increased levels of IFN-I and IRF7 protein in the growing tumor, indicating that the enhanced antitumor immune response observed in Oasl1 (-/-) mice was caused by higher IFN-I production in Oasl1 (-/-) mice. Collectively, these results show that OASL1 deficiency promotes the antitumor immune response, and thus, OASL1 could be a good therapeutic target for treating tumors.

Abstract
BACKGROUND The prevalence of post-transplantation immunoglobulin A nephropathy (PTIgAN) and diabetes mellitus (PTDM) increases with time after transplantation, and recognition and management of these conditions is becoming more important in renal allograft recipients as graft survival increases. METHODS We explored the influence of concurrent PTDM on renal allograft histology and function in 111 cases with PTIgAN diagnosed from 2000 to 2010 at our institution. RESULTS Sixteen patients (14.4%) had PTDM at the time of diagnosis of PTIgAN, which increased to 28 patients (25.2%) at the last follow-up (10.4 years after transplantation). Donor ages were younger in PTIgAN patients with concurrent PTDM. However, other clinical and demographic data were not significantly different between PTIgAN patients with and without PTDM. Histologically, Banff "mm" scores were higher and "M1" of the Oxford classification was more frequent in PTIgAN patients with concurrent PTDM than in patients without PTDM, but the difference did not reach statistical significance. Serum creatinine levels and proteinuria at the time of biopsy and overall graft survival did not vary according to the presence of PTDM both at biopsy and at the last follow-up. CONCLUSIONS Concurrent PTDM does not significantly influence graft function or outcome for 10 years after transplantation in PTIgAN patients.

Abstract
A superconducting transition temperature (Tc) as high as 100 K was recently discovered in one monolayer FeSe grown on SrTiO3. The discovery ignited efforts to identify the mechanism for the markedly enhanced Tc from its bulk value of 8 K. There are two main views about the origin of the Tc enhancement: interfacial effects and/or excess electrons with strong electron correlation. Here, we report the observation of superconductivity below 20 K in surface electron-doped bulk FeSe. The doped surface layer possesses all the key spectroscopic aspects of the monolayer FeSe on SrTiO3. Without interfacial effects, the surface layer state has a moderate Tc of 20 K with a smaller gap opening of 4.2 meV. Our results show that excess electrons with strong correlation cannot induce the maximum Tc, which in turn reveals the need for interfacial effects to achieve the highest Tc in one monolayer FeSe on SrTiO3. Thin FeSe film on SrTiO3 substrate becomes a superconductor with a transition temperature over 100 K, yet the origin remains controversial. Here, Seo et al. show superconductivity below 20 K on the electron-doped surface of an FeSe crystal, suggesting a decisive role of interfacial effects in the enhancement of superconductivity.

Abstract
AIMS The objective of this study was to explore antifungal metabolites targeting fungal cell envelope and to evaluate the control efficacy against anthracnose development in pepper plants. METHODS AND RESULTS A natural product library comprising 3000 microbial culture extracts was screened via an adenylate kinase (AK)-based cell lysis assay to detect antifungal metabolites targeting the cell envelope of plant-pathogenic fungi. The culture extract of Streptomyces mauvecolor strain BU16 displayed potent AK-releasing activity. Rimocidin and a new rimocidin derivative, BU16, were identified from the extract as active constituents. BU16 is a tetraene macrolide containing a six-membered hemiketal ring with an ethyl group side chain instead of the propyl group in rimocidin. Rimocidin and BU16 showed broad-spectrum antifungal activity against various plant-pathogenic fungi and demonstrated potent control efficacy against anthracnose development in pepper plants. CONCLUSIONS Antifungal metabolites produced by S. mauvecolor strain BU16 were identified to be rimocidin and BU16. The compounds displayed potent control efficacy against pepper anthracnose. SIGNIFICANCE AND IMPACT OF THE STUDY Rimocidin and BU16 would be active ingredients of disease control agents disrupting cell envelope of plant-pathogenic fungi. The structure and antifungal activity of rimocidin derivative BU16 is first described in this study.

Abstract
Purpose Questionnaire-based diagnostic criteria for atopic dermatitis (AD) have been proposed to detect the major group of AD with flexural dermatitis. We aimed to develop novel, questionnaire-based diagnostic criteria for childhood AD, which can detect more comprehensive AD including non-flexural type. Methods The draft version of questionnaire to detect childhood AD was prepared to be used for preliminary hospital- (n=1,756) and community-based (n=1,320) surveys. From analysis, the Reliable Estimation of Atopic dermatitis of ChildHood (REACH) was derived and verified in derivation (n=1,129) and validation (n=1,191) sets by community-based surveys. Results The REACH consists of 11 questions including 2 major and 9 minor criteria. AD is diagnosed as the major group of 'eczema on the antecubital or popliteal fossa' to fulfill the 2 major criteria (2M), and the minor group of 'eczema on the non-antecubital or popliteal fossa' to fulfill the 1 major plus 4 or more minor criteria (1M+4m). In the validation set, the overall 1-year AD prevalence by the REACH was estimated as 12.3% (95% CI, 10.5%-14.2%), and the REACH showed a sensitivity of 75.2%, a specificity of 96.1%, and an error rate of 6.4%. The REACH demonstrated better diagnostic performance than the ISAAC in terms of the number of misclassification (10.0%). Conclusions We propose the REACH as new full, questionnaire-based diagnostic criteria for childhood AD in epidemiological surveys. Further studies are warranted to validate the REACH in different populations or countries in the context of large-scale, epidemiological surveys.

Abstract
Aspirin hypersensitivity is a hallmark of aspirin-exacerbated respiratory disease (AERD), a clinical syndrome characterized by the severe inflammation of the respiratory tract after ingestion of cyclooxygenase-1 inhibitors. We investigated the capacity of aspirin to induce interleukin-4 (IL-4) production in inflammatory cells relevant to AERD pathogenesis and examined the associated biochemical and molecular pathways. We also compared IL-4 production in peripheral blood mononuclear cells (PBMCs) from patients with AERD vs aspirin-tolerant asthma (ATA) upon exposure to aspirin. Aspirin induced IL-4 expression and activated the IL-4 promoter in a report assay. The capacity of aspirin to induce IL-4 expression correlated with its activity to activate mitogen-activated protein kinases, to form DNA–protein complexes on P elements in the IL-4 promoter and to synthesize nuclear factor of activated T cells, critical transcription factors for IL-4 transcription. Of clinical importance, aspirin upregulated IL-4 production twice as much in PBMCs from patients with AERD compared with PBMCs from patients with ATA. Our results suggest that IL-4 is an inflammatory component mediating intolerance reactions to aspirin, and thus is crucial for AERD pathogenesis.

Abstract
UNLABELLED Backgound: This study evaluated whether the hydration status affected health-related quality of life (HRQOL) during 12 months in peritoneal dialysis (PD) patients. METHODS The hydration status and the HRQOL were examined at baseline and after 12 months using a bioimpedance spectroscopy and Kidney Disease Quality of Life-Short Form, respectively in PD patients. Four hundred eighty-one patients were included and divided according to the baseline overhydration (OH) value; normohydration group (NH group, -2L≤ OH ≤+2L, n=266) and overhydration group (OH group, OH >+2L, n=215). Baseline HRQOL scores were compared between the two groups. The subjects were re-stratified into quartiles according to the OH difference (OH value at baseline - OH value at 12 months; <-1, -1 - -0.1, -0.1 - +1, and ≥+1L). The relations of OH difference with HRQOL scores at 12 months and the association of OH difference with the HRQOL score difference (HRQOL score at baseline - HRQOL score at 12 months) were assessed. RESULTS The OH group showed significantly lower baseline physical and mental health scores (PCS and MCS), and kidney disease component scores (KDCS) compared with the NH group (all, P<0.01). At 12 months, the adjusted PCS, MCS, and KDCS significantly increased as the OH difference quartiles increased (P<0.001, P=0.002, P<0.001, respectively). In multivariate analysis, the OH difference was independently associated with higher PCS (β = 2.04, P< .001), MCS (β=1.02, P=0.002), and KDCS (β=1.06, P<0.001) at 12 months. The OH difference was independently associated with the PCS difference (β = -1.81, P<0.001), MCS difference (β=-0.92, P=0.01), and KDCS difference (β=-0.90, P=0.001). CONCLUSION The hydration status was associated with HRQOL and increased hydration status negatively affected HRQOL after 12 months in PD patients.

Abstract
PURPOSE To analyze the controversies surrounding therapeutic decision-making and the withholding of life- sustaining treatments, values held concerning therapeutic interventions of terminal cancer patients are compared between physicians and family members. MATERIALS AND METHODS 42 advanced or terminal stage cancer patients were enrolled for the study. The questionnaires were administered to the duty doctor and the family of the patients. Questions included whether to use new agents with a 15% partial efficacy and whether to use opioid analgesics, intravenous nutrition, a feeding tube, antibiotics, and hemodialysis. Additionally, we asked about the administration of CPR, ventilator application, and euthanasia. If the family permitted, the same questionnaires were given to the patients. RESULTS Of the 42 cases, 5 families refused to answer the questionnaire. Of the available 37 families, only 5 families permitted access to the patients. Of the 5 patients, 2 patients refused the questionnaire. Only 67.6% and 8.1% of families and the patients clearly understood the stage of cancer. The use of a new agent was accepted by 45.2% of the physicians and 45.9% of the families. The rankings of the acceptance of treatment in the physicians and in the families were similar. The concordance rate between the physicians and the families was lowest on ventilator application and CPR. 31% of the physicians and 43.2% of the families agreed on the issue of euthanasia. CONCLUSION Values held on issues like therapeutic decision-making and the withholding of life-sustaining treatments in terminal cancer patients are discordant between physicians and family members. In order to resolve controversies on the role of physicians in end-of-life decisions, the values of physicians as well as patients and their family members should be considered in the final decision-making process.

Abstract
PURPOSE This study was performed to estimate the response rate and toxicity of a combination chemotherapy, which included infusional 5-Fluorouracil, Leucovorin and Docetaxel in the treatment of patients with an advanced gastric carcinoma. MATERIALS AND METHODS Twenty two advanced gastric cancer patients, with a bidimensionally measurable or an evaluable disease, were enrolled in this study. The patients received a 5-fluorouracil 1, 000 mg/m2 intravenous (IV) 24 hour infusion (Day 1~3), leucovorin 20 mg/m2 (Day 1~3) and docetaxel 75 mg/m2 intravenously (Day 2) every 3 weeks. RESULTS The overall response rate was 45.0%. The median duration of response was 10.0 weeks (range: 4~24), the median time to response was 8 weeks (range: 8~20) the median time to progression was 30.0 weeks (95% CI: 16.3~43.2) and the median overall survival duration was 36.0 weeks (95% CI: 1.7~70.2). The median cumulative dose of 5-fluorouracil were 316.2 mg/m2/week and docetaxel was 23.9 mg/m2/week. WHO grade III, IV neutropenia, thromocytopenia and anemia occurred in 50.0%, 4.5% and 4.5% of patients, respectively. There were no occurrence of WHO grade III and IV nausea, vomiting, mucositis, conspitation, diarrhea, or neurotoxicity. CONCLUSION This chemotherapy regimen, including infusional 5-fluorouracil, leucovorin and docetaxel was an active agent against advanced gastric cancer patients, especially for previous chemotherapy naive patients.

Abstract
PURPOSE Retinoic acid is a substance that has previously been reported to increase radiosensitivity, but at concentrations likely to inhibit cell growth or to induce celluar differentiation. We choose head and neck cancer cell lines to investigate the role of retinoic acid as a radiosensitizer and to elucidate the mechanism through the changes in the expression of retinoid receptors and squamous cell differentiation marker. MATERIALS AND METHODS Three cell lines (PCI-50, SqCC/ Y1 and UMSCC-11B) were used. 7-AAD staining for apoptosis and Western blot analysis for RAR-alpha, beta, gamma, RXR-alpha, beta, gamma and involucrin were performed after various treatments (control, beta-all-trans-retinoic acid (t-RA) only (10 6 M), radiation only (3 Gy), radiation with t-RA). RESULTS The synergistic radiosensitivity effect of t-RA was seen only radioresistant UMSCC-11B cell line. Expression of RAR-beta was induced by t-RA in maily UMSCC- 11B cell line. RAR-alpha,gamma, and RXR-alpha, beta, gamma expression were not changed in all cell lines tested. Expression of involucrin was inhibited by t-RA in PCI-50 cell line but other two cell lines were not changed by t-RA treatment. CONCLUSION We found that only radioresistant cell line (UMSCC-11B) showed synergistic radiosensitivity effect by t-RA and this mechanism may be through RAR-beta expression induction.

Abstract
PURPOSE A single institute trial of combination chemotherapy, with paclitaxel and cisplatin, in patients with metastatic breast cancer, having failed previous combination chemotherapy, was performed. MATERIALS AND METHODS Patients were only eligible for this study if there disease had progressed, following treatment with previous chemotherapy, in either an adjuvant or a metastatic setting. Paclitaxel 175 mg/m2 was administered as a 3-hour continuous infusion on day 1, and cisplatin 80 mg/m2 was administered for 2 hours on day 2, with adequate hydration. This was repeated every 3 weeks, and continued until one of the following events occurred: disease progression, unacceptable adverse effect or treatment refusal by the patient. Intercurrent palliative radiotherapy, or concurrent hormonal therapy, was permitted, depending on each patient's status. All the endpoints were evaluated under the principle of intention to treat analysis. RESULTS A total of 24 patients entered the study, and 18 had at least one measurable lesion, but 6 did not. The objective response rate of the 18 patients was 50%(9/18). Two were complete responses and seven showed partial responses. The median response duration, progression free and overall survival were 5.3 months (range, 4~18), 6 months (95% CI, 5~7) and 12 months (95% CI, 7~17), respectively. 67% of the planned dose was administered. Out of a total 135 cycles administered, about 20% of cycles showed grade 3 or 4 leukopenia and 7% showed grade 3 thrombocytopenia. Two patients suffered from pneumonia, and one experienced neutropenic fever. Mucositis, greater than grade 3, existed in three cases. No treatment related deaths were reported. CONCLUSION The combination chemotherapy, with paclitaxel and cisplatin, was active in the treatment of metastatic breast cancer patients having failed previous chemotherapy.

PURPOSE We evaluated the treatment efficacy including survival and recurrence, and factors associated with recurrence in osteosarcoma patients treated with preoperative chemotherapy, surgery, and adjuvant chemotherapy. MATERIALS AND METHODS Forty nine patients with osteosarcoma were treated with preoperative chemotherapy with intra-arterial cisplatin and adriamycin infusion for 3 cycles, followed by surgery. According to the pathologic response, if tumor was necrotized more than 90%, the same adjuvant chemotherapy was reintroduced for 3 cycles, and if the response was not enough, then the salvage regimen was introduced. Plain chest film and chest CT scan were taken monthly and every 3 months, respectively. When tumor recurred, the metastasectomy was performed whenever possible. RESULTS Forty three patients were evaluable with amedian follow up of 53 months. Five-year disease-free and overallsurvival rate was 47.0% and 66.9%, respectively. The recurrence was observed in 22 patients (51.2%) with median time of 12.5 months. Baseline alkaline phosphatase (ALP) was the only significant factor for recurrence (p=0.03) and the patients with the possibility of metastasectomy recurrence showed higher post-relapse survival compared to other treatment modalities (26 momths vs 5~12 months). CONCLUSION These results indicates that pre- and postoperative chemotherapy with intra-arterial cisplatin and adriamycin infusion showed comparable treatment efficacy and acceptable toxicities.

Abstract
PURPOSE To evaluate the efficacy and toxicity of combination chemotherapy with low-dose paclitaxel and cisplatin in patients with advanced non-small cell lung cancer. MATERIALS AND METHODS Chemotherapy-naive patients with unresectable, pathologically proven non-small cell lung cancer were eligible for inclusion in the study. Patients received paclitaxel (145 mg/m2 iv 3 hour D1) and cisplatin (60 mg/m2 iv D1) every 3 weeks. RESULTS Forty-two patients were enrolled between February 2000 and February 2001. The median age was 53.5 years. Patients with adenocarcinoma numbered 29, squamous cell carcinoma 7, large cell carcinoma 3, and undifferentiated carcinoma 3. Seventeen patients had stage IIIB, 19 had stage IV disease and the remaining 6 displayed recurred disease after previous surgical resection. Four patients terminated treatment early because of hypersensitivity (1) and severe emesis (3). Of the 38 evaluable patients, 14 had PR and the response rate was 36.8%. Among partial responders, 6 patients received additional chest radiation. The median duration of response was 47.9 weeks and the median overall survival was 54.0 weeks. Of the total 176 courses, 14 were delayed, 22 required dose reduction, and grade 3~4 neutropenia occurred in 5.6% of courses. Only one episode of neutropenic fever developed and there were no treatment- related mortalities. Other toxicities were generally mild. CONCLUSION The combination chemotherapy with low-dose paclitaxel and cisplatin was effective and tolerable in patients with advanced non-small cell lung cancer.

Abstract
AIM To investigate the distinguishing features of artefactual stenosis from true stenosis at the genu of the petrous internal carotid artery (ICA) on time of flight (TOF) magnetic resonance angiography (MRA). MATERIALS AND METHODS Both TOF MRA and digital subtraction angiography (DSA) were performed in 65 patients with 74 vessels who demonstrated artefactual stenosis in 43 patients with 50 vessels and true stenosis in 22 patients with 24 vessels. The following findings of the signal loss were compared between the two groups: (1) margin, (2) darkness, (3) the presence of bilaterality, (4) the presence of tandem arterial stenosis, (5) the location of the epicentre, and (6) length. RESULTS In five out of the six evaluated items, statistically significant differences were present between the two groups (p<0.00 in all five items). Artefactual stenosis more frequently showed signal loss with ill-defined margins (47/50), less darkness compared to the background darkness (46/50), the absence of tandem arterial stenosis (35/50), epicentre at the genu (34/50), and shorter length (2.57 ± 0.68 mm). No significant difference was noted in the presence of bilaterality of signal loss between the two groups (p=0.706). CONCLUSION Several MRA features can be useful for suggesting artefactual stenosis rather than true stenosis at the genu of the petrous ICA on TOF MRA.

Abstract
Background The human immunodeficiency virus type-1 (HIV-1) nucleocapsid protein (NC) is an essential and multifunctional protein involved in multiple stages of the viral life cycle such as reverse transcription, integration of proviral DNA, and especially genome RNA packaging. For this reason, it has been considered as an attractive target for the development of new anti-HIV drugs. Although a number of inhibitors of NC have been reported thus far, the search for NC-specific and functional inhibitor(s) with a good antiviral activity continues. Results In this study, we report the identification of A1752, a small molecule with inhibitory action against HIV-1 NC, which shows a strong antiviral efficacy and an IC50 around 1 μM. A1752 binds directly to HIV-1 NC, thereby inhibiting specific chaperone functions of NC including Psi RNA dimerization and complementary trans-activation response element (cTAR) DNA destabilization, and it also disrupts the proper Gag processing. Further analysis of the mechanisms of action of A1752 also showed that it generates noninfectious viral particles with defects in uncoating and reverse transcription in the infected cells. Conclusions These results demonstrate that A1752 is a specific and functional inhibitor of NC with a novel mode of action and good antiviral efficacy. Thus, this agent provides a new type of anti-HIV NC inhibitor candidate for further drug development.

Abstract
BACKGROUND/OBJECTIVES The effect of aspirin and clopidogrel in a fixed-dose combination (FDC) on platelet function was compared with separate formulations in patients that had undergone percutaneous coronary intervention (PCI) with drug-eluting stent (DES). METHODS This was a phase IV, prospective, multicenter, single-arm, non-inferiority study. Patients that had taken aspirin 100 mg and clopidogrel 75 mg once daily as separate formulations for >6 months after PCI with DES were enrolled, and then switched to an aspirin/clopidogrel FDC once-daily for 4 weeks. Platelet reactivity was determined using the VerifyNow® P2Y12 assay at baseline (immediately prior to switching) and 4 weeks later. RESULTS A total of 648 patients (the full-analysis population; age, 63.6±9.0 years; male, 76.5%) finished the study, and 565 (the per-protocol population) completed without protocol violations. In the per-protocol population, the % inhibitions of P2Y12 and ARU were not significantly different between baseline and after 4 weeks of FDC treatment (29.2±20.0% to 29.0±19.9%, P=0.708; 445.1±69.2 to 446.2±63.0, P=0.799, respectively) and the difference in P2Y12 inhibition observed did not exceed the predetermined limit of non-inferiority (95% CI, -0.9 to 1.3). In the full-analysis population, the % inhibitions of P2Y12, PRU, and ARU were not significantly changed after 4 weeks of FDC treatment. CONCLUSIONS This study demonstrates that the efficacy of platelet inhibition by an aspirin/clopidogrel FDC was not inferior to that of separate aspirin and clopidogrel formulations in patients that had undergone PCI with DES.

Abstract
Decursin, a bioactive phytochemical isolated from Angelica gigas Nakai (danggwi), has shown preclinical anticancer efficacy in various cancer models. However, the antitumor effect of decursin in melanoma models remains undefined. The antitumor activities of decursin were investigated in B16F10 cells in vitro and in vivo. In this study, we show that treatment with decursin inhibited cell proliferation in a dose-dependent manner in B16F10 cells, but not in normal cells. Decursin also induced apoptosis in B16F10 cells, as determined by annexin V-staining assay and transferase-mediated nick-end labeling (TUNEL) staining assay. Decursin increased the phosphorylation of p38 as well as the expression of Bax while decreasing the phosphorylation of extracellular signaling-regulated kinase (ERK) and the expression of Bcl-2 in B16F10 cells. Moreover, decursin activated caspase-3 in B16F10 cells and xenograft tumor tissue. Together, these findings support further investigations into the potential use of decursin in the treatment of melanoma cells.

Abstract
Circadian disruption is the bane of modern existence and its deleterious effects on health; in particular, diabetes and metabolic syndrome have been well recognized in shift workers. Recent human studies strongly implicate a 'dose-dependent' relationship between circadian disruption and diabetes. Genetic and environmental disruption of the circadian clock in rodents leads to diabetes secondary to β-cell failure. Deletion of Bmal1, a non-redundant core clock gene, leads to defects in β-cell stimulus-secretion coupling, decreased glucose-stimulated ATP production, uncoupling of OXPHOS and impaired glucose-stimulated insulin secretion. Both genetic and environmental circadian disruptions are sufficient to induce oxidative stress and this is mediated by a disruption of the direct transcriptional control of the core molecular clock and Bmal1 on Nrf2, the master antioxidant transcription factor in the β-cell. In addition, circadian disruption also leads to a dysregulation of the unfolded protein response and leads to endoplasmic reticulum stress in β-cells. Both the oxidative and endoplasmic reticulum (ER) stress contribute to an impairment of mitochondrial function and β-cell failure. Understanding the basis of the circadian control of these adaptive stress responses offers hope to target them for pharmacological modulation to prevent and mitigate the deleterious metabolic consequences of circadian disruption.

Abstract
The propagation of human pluripotent stem cells (hPSCs) in conditioned medium derived from human cells in feeder-free culture conditions has been of interest. Nevertheless, an ideal humanized ex vivo feeder-free propagation method for hPSCs has not been developed; currently, additional exogenous substrates including basic fibroblast growth factor (bFGF), a master hPSC-sustaining factor, is added to all of culture media and synthetic substrata such as Matrigel or laminin are used in all feeder-free cultures. Recently, our group developed a simple and efficient protocol for the propagation of hPSCs using only conditioned media derived from the human placenta on a gelatin-coated dish without additional exogenous supplementation or synthetic substrata specific to hPSCs. This protocol has not been reported previously and might enable researchers to propagate hPSCs efficiently in humanized culture conditions. Additionally, this model obviates hPSC contamination risks by animal products such as viruses or unknown proteins. Furthermore, this system facilitates easy mass production of hPSCs using the gelatin coating, which is simple to handle, dramatically decreases the overall costs of ex vivo hPSC maintenance.

Abstract
BACKGROUND AND PURPOSE Crossed cerebellar diaschisis, not only a secondary result of supratentorial infarction but also an indicator of clinical outcomes, has frequently been reported on PET and SPECT but has been rarely described with arterial spin-labeling MR imaging. The purpose of this study was to determine the ability of arterial spin-labeling MR imaging to evaluate crossed cerebellar diaschisis compared with that of SPECT. To our knowledge, this is the first study to validate arterial spin-labeling in crossed cerebellar diaschisis by using SPECT as a reference standard. MATERIALS AND METHODS This study included 16 patients in whom crossed cerebellar diaschisis was shown on SPECT and 10 control subjects in whom crossed cerebellar diaschisis was not shown on SPECT. During the qualitative analysis, asymmetric cerebellar perfusion on arterial spin-labeling was divided into 1 of the following 3 grades by 2 blinded observers: the affected cerebellum was isointense compared with the unaffected cerebellum (grade I), it was slightly hypointense (grade II), or it was markedly hypointense (grade III). In the quantitative analysis, asymmetry indices were calculated by using SPECT and arterial spin-labeling images. For statistical analysis, κ statistics, the interobserver correlation coefficient, the independent t test, Pearson correlation, and linear regression analysis were used. RESULTS Almost all the diagnoses of crossed cerebellar diaschisis on SPECT were noted on arterial spin-labeling in both qualitative and quantitative analyses with good interobserver agreement (κ = 0.961; interobserver correlation coefficient, 0.806). The mean asymmetry index of arterial spin-labeling (26.06 ± 9.00) was significantly larger than that for SPECT (15.28 ± 5.34; P < .001). There was a significant positive correlation between the asymmetry indices obtained for SPECT and those for arterial spin-labeling (r = 0.77 [95% CI, 0.443-0.916]; P < .001). The relationship of asymmetry indices between SPECT and arterial spin-labeling (x, y) was calculated as y = 6.2131 + 1.2986x (R(2) = 0.592; P < .001). CONCLUSIONS Arterial spin-labeling can be a noninvasive alternative to SPECT for evaluating crossed cerebellar diaschisis.

Abstract
OBJECTIVE Developing a parameter to predict bone marrow invasion by non-Hodgkin's lymphoma is an important unmet medical need for treatment decisions. This study aimed to confirm the validity of the hypothesis that bone marrow plasma vascular endothelial growth factor level might be correlated with the risk of bone marrow involvement and the prognosis of patients with diffuse large B-cell non-Hodgkin's lymphoma. METHODS Forty-nine diffuse large B-cell lymphoma patients treated with rituximab, cyclophosphamide, daunorubicin, vincristine and prednisolone regimen were enrolled. Vascular endothelial growth factor level was measured with enzyme-linked immunosorbent assay. The validity of bone marrow plasma vascular endothelial growth factor level and bone marrow vascular endothelial growth factor level per platelet count for predicting treatment response and survival after initial rituximab, cyclophosphamide, daunorubicin, vincristine and prednisolone combined chemotherapy was assessed. RESULTS Bone marrow plasma vascular endothelial growth factor level per platelet count was significantly associated with old age (≥ 65 years), poor performance score (≥ 2), high International prognosis index (≥ 3) and bone marrow invasion. The patients with high bone marrow plasma vascular endothelial growth factor level per platelet count (≥ 3.01) showed a significantly lower complete response rate than the others. On Kaplan-Meier survival curves, the patients with high bone marrow plasma vascular endothelial growth factor levels (≥ 655 pg/ml) or high bone marrow plasma vascular endothelial growth factor level per platelet count (≥ 3.01) demonstrated a significantly shorter overall survival and progression-free survival than the others. In the patients without bone marrow involvement, bone marrow plasma vascular endothelial growth factor level per platelet count had a significant relationship with overall survival and progression-free survival. Multivariate analysis revealed that the patients without BM invasion showing high level of bone marrow plasma vascular endothelial growth factor per platelet count had significantly shorter progression-free survival and overall survival. CONCLUSIONS Bone marrow plasma vascular endothelial growth factor level per platelet count might be associated with bone marrow invasion by diffuse large B-cell lymphoma and is correlated with clinical outcomes after treatment.

Abstract
Background and Objectives We compared the efficacy and safety of valsartan and rosuvastatin combination therapy with each treatment alone in hypercholesterolemic hypertensive patients. Subjects and Methods Patients who met inclusion criteria were randomized to receive 1 of the following 2-month drug regimens: valsartan 160 mg plus rosuvastatin 20 mg, valsartan 160 mg plus placebo, or rosuvastatin 20 mg plus placebo. The primary efficacy variables were change in sitting diastolic blood pressure (sitDBP) and sitting systolic blood pressure (sitSBP), and percentage change in low-density lipoprotein-cholesterol (LDL-C) in the combination, valsartan, and rosuvastatin groups. Adverse events (AEs) during the study were analyzed. Results A total of 354 patients were screened and 123 of them were finally randomized. Changes of sitDBP by least squares mean (LSM) were -11.1, -7.2, and -3.6 mm Hg, respectively, and was greater in the combination, as compared to both valsartan (p=0.02) and rosuvastatin (p<0.001). Changes of sitSBP by LSM were -13.2, -10.8, and -4.9 mm Hg, and was greater in the combination, as compared to rosuvastatin (p=0.006) and not valsartan (p=0.42). Percentage changes of LDL-C by LSM were -52, -4, and -47% in each group, and was greater in the combination, as compared to valsartan (p<0.001), similar to rosuvastatin (p=0.16). Most AEs were mild and resolved by the end of the study. Conclusion Combination treatment with valsartan and rosuvastatin exhibited an additive blood pressure-lowering effect with acceptable tolerability, as compared to valsartan monotherapy. Its lipid lowering effect was similar to rosuvatatin monotherapy.

Abstract
BACKGROUND Coronary artery disease (CAD) is one of the leading causes of mortality in kidney transplantation (KT) recipients. Noninvasive coronary angiography with the use of multidetector computerized tomography (MDCT) is feasible with high sensitivity and negative predictive value to evaluate CAD. However, few studies have been conducted to elucidate the applicability of MDCT in KT. This study was designed to evaluate the prevalence and severity of CAD with the use of MDCT angiography in asymptomatic KT recipients. METHODS From September 2011 to November 2013, MDCT angiography was performed on 90 renal transplant recipients who had no pre-transplantation CAD history and stabilized post-transplantation renal function for 6-18 months. According to the MDCT results, we divided our study population into 2 groups: The no-CAD group (n = 36; 40.0%) and the CAD group (n = 54; 60.0%). Severity of CAD was categorized as follows: mild CAD, 1 vessel obstructive, 2 vessels obstructive (or in the proximal left anterior descending), and 3 vessels obstructive (or left main). RESULTS Among the risk factors, pre-transplantation diabetes mellitus and lower levels of high-density lipoprotein, higher parathyroid hormone levels, higher coronary artery calcification scores, and rejection episodes were independent factors for CAD. Thirty-two (59.3%) of the CAD group had mild obstructive lesions and 22 (40.7%) had obstructive lesions in >1 vessel according to MDCT angiography. CONCLUSIONS MDCT angiography is a useful and noninvasive method for detecting CAD even in asymptomatic KT recipients.

Abstract
AIM Chronic myelogenous leukemia (CML) chronic phase (CP) patients cannot tolerate a standard dose (400 mg/day) of imatinib mesylate (IM), sometimes needing a reduced dose. This study aimed to find convenient clinical indexes, rather than plasma trough levels of IM, to define the appropriate IM dosage. METHODS Seventy CML CP patients who experienced an IM dose reduction, or a temporary cessation, were enrolled from 2002 to 2010. The IM treatment was resumed and maintained at either ≥400 mg in 25 patients (35.7%; group ≥400 mg) or at ≤300 mg in 45 patients (64.3%; group ≤300 mg). The various clinical characteristics of these patients were evaluated. The plasma trough level of IM was monitored in 20 patients from group ≤300 mg. RESULTS Via multivariate analysis, the IM dosage divided by the body surface area (BSA) was an important index, presupposing a complete cytogenetic response at 12 months (CCyR12). Patients with IM/BSA >206.7 mg/m2 showed a higher probability of CCyR12 than others. The IM/BSA (221.7 mg/m2) in group ≤300 mg was higher than in group ≥400 mg (207.6 mg/m2). The sustained response and survival rate of group ≤300 mg was comparable to that of group ≥400 mg. The plasma trough level of IM was significantly correlated with the IM/BSA. CONCLUSION Our study suggests that IM dose adjustments, based on IM/BSA, could improve the clinical outcomes in CML CP patients.

Abstract
Here we report a new chemical inhibitor against HIV-1 with a novel structure and mode of action. The inhibitor, designated as A1836, inhibited HIV-1 replication and virus production with a 50% inhibitory concentration (IC₅₀) of 2.0 μM in an MT-4 cell-based and cytopathic protection antiviral assay, while its 50% cytotoxic concentration (CC₅₀) was much higher than 50 μM. Examination of the effect of A1836 on in vitro HIV-1 reverse transcriptase (RT) and integrase showed that neither were molecular targets of A1836. The characterization and re-infection assay of the HIV-1 virions generated in the presence of A1836 showed that the synthesis of early RT products in the cells infected with the virions was inhibited dose-dependently, due in part to abnormal protein formation within the virions, thus resulting in an impaired infectivity. These results suggest that A1836 might be a novel candidate for the development of a new type of HIV-1 inhibitor.

Abstract
Hosta plantaginea (Lam.) Asch. is an herbaceous perennial plant with ornamental value. In August 2013, water-soaked spots and wet rot were found on flowers of H. plantaginea in a garden bedded out for landscaping in Hongcheon County, Korea. Symptoms initially appeared as water-soaked spots at the tips of flowers. Dark gray spots on flower petals often coalesced and led to rotting of flowers, with abundant sporulation. However, no symptoms were found on the leaves. Approximately 30% of the flowers were affected in the landscape bed. A fungal isolate was obtained by plating surface-disinfested diseased flower tissue on potato dextrose agar (PDA). Fungal colonies covering the plate (diam. 90 mm) in 48 h were white at first, with abundant aerial mycelia, but later turned pale yellow with abundant sporangiola. Sporangiophores bearing sporangiola were aseptate, hyaline, and usually arose from infected tissue. Sporangiola were ellipsoid to ovoid, indehiscent, brown to dark brown, pediculate, 7 to 12 μm wide and 9 to 20 μm high, and showed longitudinal striations at high magnification. Sporangia were few-spored to multispored, pale brown to brown, and 50 to 150 μm. Sporangiospores from sporangia were broadly ellipsoid, brown to pale brown, with hyaline polar appendages, 8 to 10 μm wide and 15 to 22 μm high. Zygospores were not observed. The morphological and cultural characteristics, especially based on shape and striation of sporangiola, were identical with those of Choanephora cucurbitarum (Berk. & Ravenel) Thaxt. (2,3). A representative specimen was deposited in the Korea University Herbarium (KUS-F27540). Genomic DNA was extracted using a DNeasy Plant Mini Kit (Qiagen Inc., Valencia, CA). The primers ITS1/ITS4 and NL1/LR3 were used to amplify the internal transcribed spacer (ITS) region of rDNA and the D1/D2 region of the large subunit (LSU), respectively (4). The PCR products were purified and directly sequenced. The resulting 594-bp ITS and 680-bp D1/D2 sequences were submitted to GenBank (Accession Nos. KM200034 and KM200035). A GenBank BLAST search of the fungal database showed that the sequences of ITS and D1/D2 regions matched those of C. cucurbitrarum (JN943006 and JN939195) with 100% similarity. A pathogenicity test was conducted by spraying three healthy potted plants (2 months old) with a sporangiola suspension (2 × 104 conidia/ml). Another three potted plants of the same age were treated with sterile water and served as controls. The plants were kept in humid chambers for 2 days and placed in a greenhouse (28°C and 60 to 80% RH). After 4 to 5 days, water-soaked spots were evident on the flowers of inoculated plants. No symptoms were observed on control plants. A pathogenicity test was conducted twice with the same results, fulfilling Koch's postulates. C. cucurbitarum has a wide host range but has not been previously reported to cause disease on H. plantaginea (1). To our knowledge, this is the first report of C. cucurbitarum on H. plantaginea globally as well as in Korea. Choanephora rot of flowers is an issue under high-moisture conditions, so allowing for adequate airflow and a dry plant canopy should aid in disease suppression. References: (1) D. F. Farr and A. Y.

Abstract
Basic fibroblast growth factor (bFGF) is a crucial factor sustaining human pluripotent stem cells (hPSCs). We designed this study to search the substitutive factors other than bFGF for the maintenance of hPSCs by using human placenta-derived conditioned medium without exogenous bFGF (hPCCM-), containing chemokine (C-X-C motif) receptor 2 (CXCR2) ligands, including interleukin (IL)-8 and growth-related oncogene α (GROα), which were developed on the basis of our previous studies. First, we confirmed that IL-8 and/or GROα play independent roles to preserve the phenotype of hPSCs. Then, we tried CXCR2 blockage of hPSCs in hPCCM- and verified the significant decrease of pluripotency-associated genes expression and the proliferation of hPSCs. Interestingly, CXCR2 suppression of hPSCs in mTeSR™1 containing exogenous bFGF decreased the proliferation of hPSCs while maintaining pluripotency characteristics. Lastly, we found that hPSCs proliferated robustly for more than 35 passages in hPCCM- on a gelatin substratum. Higher CXCR2 expression of hPSCs cultured in hPCCM- than those in mTeSR™1 was observable. Our findings suggest that CXCR2 and its related ligands might be novel factors comparable to bFGF supporting the characteristics of hPSCs and hPCCM- might be useful for the maintenance of hPSCs as well as for the accurate evaluation of CXCR2 role in hPSCs without the confounding influence of exogenous bFGF.

Abstract
BACKGROUND Despite the advances in acute myeloid leukemia (AML) treatment, the prognosis of elderly patients remains poor and no definitive treatment guideline has been established. In the present study, we aimed to evaluate the effectiveness of intensive chemotherapy in elderly AML patients and to determine which subgroup of patients would be most responsive to the therapy. METHODS We retrospectively analyzed 84 elderly patients: 35, 19, and 30 patients were administered intensive chemotherapy, low-dose chemotherapy, and supportive care, respectively. RESULTS Among those who received intensive chemotherapy, there were 17 cases of remission after induction chemotherapy; treatment-related mortality was 22.9%. The median overall survival was 7.9 months. Multivariate analysis indicated that the significant prognostic factors for overall survival were performance status, fever before treatment, platelet count, blast count, cytogenetic risk category, and intensive chemotherapy. Subgroup analysis showed that intensive chemotherapy was markedly effective in the relatively younger patients (65-70 years) and those with de novo AML, better-to-intermediate cytogenetic risk, no fever before treatment, high albumin levels, and high lactate dehydrogenase levels. CONCLUSIONS Elderly AML patients had better outcomes with intensive chemotherapy than with low-intensity chemotherapy. Thus, appropriate subgroup selection for intensive chemotherapy is likely to improve therapeutic outcome.

Abstract
Korean rose bitterling (Rhodeus uyekii) is a freshwater fish endemic to Korea. Natural populations of this species have experienced severe declines as a result of habitat fragmentation and water pollution. To conserve and restore R. uyekii, the genetic diversity of this species needs to be assessed at the population level. Eighteen novel polymorphic microsatellite loci for R. uyekii were developed using an enriched partial genomic library. Polymorphisms at these loci were studied in 150 individuals collected from three populations. The number of alleles at each locus ranged from 3 to 47 (mean = 17.1). Within the populations, the observed heterozygosity ranged from 0.032 to 1.000, expected heterozygosity from 0.082 to 0.967, and polymorphism information content from 0.078 to 0.950. Six loci showed significant deviation from Hardy-Weinberg equilibrium after Bonferroni's correction, and no significant linkage disequilibrium was detected between most locus pairs, except in three cases. These highly informative microsatellite markers should be useful for genetic population structure analyses of R. uyekii.

Abstract
BACKGROUND Combination chemotherapy consisting of ifosfamide, methotrexate, etoposide, and prednisolone (IMEP) was active as first-line and second-line treatment for extranodal natural killer/T-cell lymphoma (NTCL). METHODS Forty-four patients with chemo-naïve stage I/II NTCL were enrolled in a prospective, multicenter, phase II study and received six cycles of IMEP (ifosfamide 1.5 g/m(2) on days 1-3; methotrextate 30 mg/m(2) on days 3 and 10; etoposide 100 mg/m(2) on days 1-3; and prednisolone 60 mg/m(2) per day on days 1-5) followed by involved field radiotherapy (IFRT). RESULTS Overall response rates were 73% (complete remission [CR] in 11 of 41 evaluable patients [27%]) after IMEP chemotherapy and 78% (CR 18 of 27 evaluable patients [67%]) after IMEP followed by IFRT. Neutropenia and thrombocytopenia were documented in 33 patients (75%) and 7 patients (16%), respectively. Only 8 patients (18%) experienced febrile neutropenia. Three-year progression-free survival (PFS) and overall survival (OS) were 66% and 56%, respectively. High Ki-67 (≥70%) and Ann Arbor stage II independently reduced PFS (p = .004) and OS (p = .001), respectively. CONCLUSION Due to the high rate of progression during IMEP chemotherapy, IFRT needs to be introduced earlier. Moreover, active chemotherapy including an l-asparaginase-based regimen should be use to reduce systemic treatment failure in stage I/II NTCL.

Abstract
BACKGROUND The relationship between relative adrenal insufficiency (RAI) and chronic liver disease is unclear. AIM To determine the frequency with which RAI is observed in noncritically ill patients at various stages of chronic liver disease, and the correlation between RAI and disease severity and long-term mortality. METHODS In total, 71 non-critically ill patients with liver cirrhosis (n = 54) and chronic hepatitis (n = 17) were evaluated prospectively. A short stimulation test (SST) with 250 μg of corticotrophin was performed to detect RAI. RAI was defined as an increase in serum cortisol of <9 μg/dL in patients with a basal total cortisol of <35 μg/dL. RESULTS RAI was observed in only 13 (24.1%) of 54 patients with cirrhosis. Compared to those without RAI, cirrhotic patients with RAI had significantly higher Child-Turcotte-Pugh score (10.3 ± 1.7 vs. 7.1 ± 1.8, mean ± s.d., P < 0.001) and Model for End-Stage Liver Disease score (14.5 ± 6.6 vs. 9.4 ± 3.7, P = 0.017). The cortisol response to corticotropin was negatively correlated with the severity of cirrhosis (P < 0.05). In addition, the mortality rate was higher in cirrhotic patients with RAI (69.2%) than in those without RAI (4.9%; P < 0.001) during the follow-up period of 20.1 ± 13.5 months (range, 5.8-51.1 months). The cumulative 1-year survival rates in cirrhotic patients with and without RAI were 69.2% and 95.0%, respectively (P = 0.05), while the corresponding cumulative 3-year survival rates were 0% and 95.0% (P < 0.001). CONCLUSIONS Relative adrenal insufficiency is more commonly observed in those with severe cirrhosis, and is clearly associated with more advanced liver disease and a shortened long-term survival. This suggests that relative adrenal insufficiency is an independent prognostic factor in non-critically ill patients with cirrhosis.

Abstract
Perennial statice is widely cultivated worldwide. In Korea, hybrid statice (Limonium latifolium × bellidifolium) is grown as a commercial cut flower crop in polyethylene-film-covered greenhouses. In April 2013, hundreds of hybrid statice plants of the cvs. Yellow Cream and Pinky Cream were found symptomatic of a previously unknown disease, with 10 to 15% incidence in 10 greenhouses of 1,600 m2 surveyed in Gochang County, Korea. Affected stems turned dark brown and were usually covered with a fungus resembling the hoar-frost fungus, Botryosporium longibrachiatum (3), especially in a cool and humid environment. Symptoms consisted of stem blackening, as is typical for burley tobacco (1) and sweet basil (2). According to the farmer of the hybrid statice, stems blackened in the winter and spring of January to April when the tunnels were mostly closed, thus reaching 100% relative humidity (RH) every night due to poor ventilation. The fungus had an elongate main axis with lateral fertile branches in acropetal succession. Conidiophores were simple, erect, macronematous, 32 to 79 μm in length, with a terminal cluster of three to five ampullae. Conidiogneous cells were polyblastic. Conidia were ellipsoidal, elliptical-fusiform, hyaline, 7.6 to 9.5 × 3.0 to 4.2 μm. Colonies on potato dextrose agar (PDA) were floccose, non-pigmented, and chalk-white in color. Morphological and cultural characteristics of the fungus were consistent with previous reports of B. longibrachiatum (Oudem.) Maire (2,3). A voucher specimen was deposited in the Korea University Herbarium (KUS). Isolate KUS-F27305 was submitted to the Korean Agricultural Culture Collection (Accession No. KACC47263). Fungal DNA was extracted from isolate KACC47263 with DNeasy Plant Mini Kits. The complete internal transcribed spacer (ITS) region of rDNA was amplified with the primers ITS1/ITS4 and sequenced. The resulting sequence of 604 bp was deposited in GenBank (Accession No. KF372591). A BLAST search in GenBank exhibited ≥99% nucleotide identity with the ITS sequence of B. longibrachiatum (JX666334) from sweet basil in Korea. To confirm pathogenicity, colonized mycelial agar blocks from isolate KACC47263 were transferred individually onto stem apices and leaves of five statice plants of the cv. Yellow Cream. Five control plants were treated similarly with non-colonized agar blocks. The plants were incubated in a humid chamber at 22 ± 2°C with a 12-h photoperiod for 48 h, and then maintained in 100% RH. After 3 to 4 days, necrotic lesions identical to those observed in the original greenhouses, started to develop on the stem and leaves of inoculated plants, leading to blackened stems covered with the hoar-frost fungus after 14 days. B. longibrachiatum was re-isolated from the lesions of inoculated plants, fulfilling Koch's postulates. No symptoms were observed on control plants. The pathogenicity test was repeated with the cv. Pinky Cream with identical results. To our knowledge, this is the first report of B. longibrachiatum infecting perennial statice globally as well as in Korea. We propose the name black stem of statice for this disease, analogous to the disease on basil (2). References: (1) T. R. Anderson and T. W. Welacky. Plant Dis. 67:1158, 1983. (2) J. H. Park et al.

Abstract
AIM We present the oncologic outcomes of laparoscopic nephroureterectomy management of pT3 upper urinary tract urothelial carcinoma. METHODS Between October 2003 and January 2011, 50 patients with pT3 upper urinary tract urothelial carcinoma which had pathologically confirmed underwent laparoscopic nephroureterectomy at our institution. Demographic data, perioperative results, pathological findings and oncologic outcomes were reviewed and analyzed retrospectively. RESULTS There were 36 patients (72%) of high grade lesion and 14 patients (28%) of low grade lesion. Lymphovascular invasion was observed in 16 patients (32%) and the surgical margin was positive in one patient. N stage was pN0 in 16 (32%), pN1 in 3 (6%), pN2 in 1 (2%) and pN3 in 1 (2%). The 5-year overall survival rate was 52.6% and the 5-year cancer-specific survival rate was 65.3%. Overall recurrence developed in 23 patients. There were 10 patients (20%) of urothelial recurrence which were all occurred in the bladder at the mean period of 13.6 months, and 7 patients of them were invasive bladder cancer. There were 16 patients (32%) of non-urothelial recurrence developed at the mean period of 9.69 months. On multivariate analyses lymphadenopathy and lymph node involvement of cancer (N+) were identified as independent predictive factors for the cancer-specific survival, and concomitant bladder tumor, grade and lymphovascular invasion were identified as independent predictive factors for the overall recurrence free survival. CONCLUSION Laparoscopic nephroureterectomy in patients with high stage upper urinary tract urothelial carcinoma appear comparable to those of open surgery in the regard of oncologic outcomes.

Abstract
New Guinea impatiens, Impatiens hawkeri W. Bull, is widely cultivated as a potted plant and garden plant. In July 2013, hundreds of young plants (cv. Fanfare) showing symptoms of leaf spot with approximately 50% incidence were found in polyethylene tunnels in Yongin City, Korea. Leaf spots were circular to oblong, reaching 6 mm or more in diameter. The spots were initially uniformly brown to reddish brown, turning gray with reddish brown margin. Diseased plants defoliated prematurely and were abandoned without marketing due to signs of discoloration and yellowing on leaves. A cercosporoid fungus was consistently observed in association with disease symptoms. Stromata were brown, small, and composed of a few swollen hyphal cells. Conidiophores were emerging through the cuticle, fasciculate (n = 2 to 20), olivaceous to brown, paler toward the apex, straight to mildly curved, geniculate, 30 to 260 μm long, 3.5 to 5 μm wide, 1- to 6-septate, and with conspicuous conidial scars. Conidia were hyaline and acicular. Smaller conidia were straight and longer conidia were mildly curved. Conidia were subacute to obtuse at the apex, truncate to obconically truncate at the base, 2- to 18-septate, 30 to 320 × 3.5 to 5.5 μm, and with thickened, darkened hila at the base. Morphological characteristics of the fungus were consistent with the previous reports of Cercospora fukushiana (Matsuura) W. Yamam. (1). Voucher specimens were housed in the Korea University herbarium (KUS). An isolate from KUS-F27438 was deposited in the Korean Agricultural Culture Collection (Accession No. KACC47640). Fungal DNA was extracted with DNeasy Plant Mini Kits (Qiagen Inc., Valencia, CA). The complete internal transcribed spacer (ITS) region of rDNA was amplified with the primers ITS1/ITS4 (4) and sequenced. The resulting sequence of 497 bp was deposited in GenBank (Accession No. KJ620981). This showed >99% similarity with sequence of C. fukushiana (EF600954) on I. balsamina from Korea. Isolate of KACC47640 was used in the pathogenicity tests. Hyphal suspensions were prepared by grinding 3-week-old colonies grown on PDA with distilled water using a mortar and pestle. Five plants were inoculated with hyphal suspensions and five plants were sprayed with sterile distilled water. The plants were covered with plastic bags to maintain a relative humidity of 100% for 24 h and then transferred to a 25 ± 2°C greenhouse with a 12-h photoperiod. Typical symptoms of necrotic spots appeared on the inoculated leaves 10 days after inoculation, and were identical to the symptoms observed in the field. C. fukushiana was re-isolated from symptomatic leaf tissues, confirming Koch's postulates. No symptoms were observed on water-inoculated control plants. Previously, leaf spots of Impatiens spp. associated with C. apii, C. balsaminae, and C. fukushiana have been reported (1,2,3). To our knowledge, this is the first report of C. fukushiana on I. hawkeri in Korea. Our observations in the nurseries of I. hawkeri suggest that low humidity with good ventilation as well as plant hygiene in greenhouses might be main strategies for preventing this disease.

Abstract
In a prospective randomized controlled study, the efficacy and safety of a continuous ambulatory peritoneal dialysis (CAPD) technique has been evaluated using one icodextrin-containing and two glucose-containing dialysates a day. Eighty incident CAPD patients were randomized to two groups; GLU group continuously using four glucose-containing dialysates (n=39) and ICO group using one icodextrin-containing and two glucose-containing dialysates (n=41). Variables related to residual renal function (RRF), metabolic and fluid control, dialysis adequacy, and dialysate effluent cancer antigen 125 (CA125) and interleukin 6 (IL-6) levels were measured. The GLU group showed a significant decrease in mean renal urea and creatinine clearance (-Δ1.2 ± 2.9 mL/min/1.73 m(2), P=0.027) and urine volume (-Δ363.6 ± 543.0 mL/day, P=0.001) during 12 months, but the ICO group did not (-Δ0.5 ± 2.7 mL/min/1.73 m(2), P=0.266; -Δ108.6 ± 543.3 mL/day, P=0.246). Peritoneal glucose absorption and dialysate calorie load were significantly lower in the ICO group than the GLU group. The dialysate CA125 and IL-6 levels were significantly higher in the ICO group than the GLU group. Dialysis adequacy, β2-microglobulin clearance and blood pressure did not differ between the two groups. The CAPD technique using one icodextrin-containing and two glucose-containing dialysates tends to better preserve RRF and is more biocompatible, with similar dialysis adequacy compared to that using four glucose-containing dialysates in incident CAPD patients.

Abstract
Yellow lupin (Lupinus luteus L.) is native to the Mediterranean region of southern Europe. In Korea, yellow lupins are cultivated for ornamental purposes. In May 2013, hundreds of yellow lupins that were grown in pots for 7 weeks in polyethylene-film-covered greenhouses were observed severely damaged by a previously unknown disease with about 30% disease incidence in a flower farm in Yongin City, Korea. Voucher specimens were deposited in the Korea University Herbarium (KUS). Early symptoms on petioles and stems appeared as small, slightly sunken, water-soaked, and circular spots. Lesions increased in size (4 to 12 μm in diameter), became more depressed, with a darkened central portion. As the disease progressed, affected areas sometimes girdled the stem and killed the shoot. Leaves were partly blighted, but less damaged. The darkened areas contained blackish acervuli from which masses of pale salmon-colored conidia were released in moist weather. Acervuli were circular to ellipsoid, 80 to 400 μm in diameter. Acervular setae were not observed. Conidia (n = 30) were long obclavate to oblong-elliptical, aguttulate, hyaline, and 10 to 18 × 3.6 to 5.2 μm with a length/width ratio of 2.6 to 3.6. Appressoria were single or occasionally in small dense clusters, medium brown, elliptical to round in outline with a smooth to lobate margin, and 8 to 14 × 6 to 9 μm. These characters were consistent with the description of Colletotrichum lupini (Bondar) Damm, P.F. Cannon & Crous (1,3). An isolate was deposited in the Korean Agricultural Culture Collection (Accession No. KACC47254). Fungal DNA was extracted with DNeasy Plant Mini DNA Extraction Kits (Qiagen Inc., Valencia, CA). The complete internal transcribed spacer (ITS) region of rDNA was amplified with the primers ITS1/ITS4 and sequenced. The resulting 545-bp sequence was deposited in GenBank (Accession No. KJ447119). The sequence showed 100% identity with sequences of C. lupini (e.g., GenBank AJ301968, JN943480, JQ948162, and KF207599). To confirm pathogenicity, inoculum was prepared by harvesting conidia with sterile distilled water from 3-week-old cultures on potato dextrose agar. A conidial suspension (2 × 105 conidia/ml) was sprayed until runoff onto the aerial parts of five healthy plants. Control plants were sprayed with sterile water. The plants were covered with plastic bags to maintain a relative humidity of 100% for 48 h and then transferred to a greenhouse. Typical symptoms of necrotic spots appeared on the inoculated leaves 6 days after inoculation, and were identical to the ones observed in the field. C. lupini was re-isolated from symptomatic leaf tissues. No symptoms were observed on control plants. The pathogenicity test was repeated twice. Anthracnose associated with C. lupini on lupins has been known from Europe (Germany, Ukraine, Austria, and Netherlands), North America (Canada and the United States), South America (Bolivia and Brazil), and Oceania (Australia and New Zealand) (2,4). To our knowledge, this is the first report of C. lupini on yellow lupins in Asia as well as in Korea. The presence of C. lupini on lupins in Asia can be considered as a potentially new and serious threat to this ornamental plant. References: (1) U. Damm et al. Stud. Mycol. 73:37, 2012. (2) D. F.
