Abstract

Background
Hwa-byung, a Korean culture-bound syndrome with both psychological and somatic symptoms, is also known as ‘anger syndrome’. It includes various physical symptoms including anxiety, a feeling of overheating, a sensation of pressure on the chest, heart palpitations, respiratory stuffiness, insomnia, and anxiety.

Methods/design
The proposed study is a single-center, double-blind, randomized, controlled trial with two parallel arms: an oriental medicine music therapy (OMMT) group and a control music therapy (CMT) group. In total, 48 patients will be enrolled into the trial. The first visit will be the screening visit. At baseline (visit 2), all participants fulfilling both the inclusion and the exclusion criteria will be split and randomly divided into two equal groups: the OMMT and the CMT (n = 24 each). Each group will receive treatment sessions over the course of 4 weeks, twice per week, for eight sessions in total. The primary outcome is the State-Trait Anxiety Inventory (STAI), and the secondary outcomes are the Hwa-byung scale (H-scale), the Center for Epidemiologic Studies Depression Scale (CES-D), the Hwa-byung visual analogue scale (H-VAS) for primary symptoms, the World Health Organization Quality of Life scale, brief version (WHOQOL-BREF), and levels of salivary cortisol. Patients will be asked to complete questionnaires at the baseline visit (visit 2), after the last treatment session (visit 9), and at 4 weeks after the end of all trial sessions (visit 10). From the baseline (visit 2) through the follow-up (visit 10), the entire process will take a total of 53 days.

Discussion
This proposed study targets patients with Hwa-byung, especially those who have exhibited symptoms of anxiety. Therefore, the primary outcome is set to measure the level of anxiety. OMMT is music therapy combined with traditional Korean medicinal theories. Unlike previously reported music therapies, for which patients simply listen to music passively, in OMMT, patients actively move their bodies and play the music. Because Hwa-byung is caused by an accumulation of blocked emotions and anger inside the body, OMMT, because of its active component, is expected to be more efficacious than pre-existing music therapies.

AbstractBackgroundΓ-Ionizing radiation (IR) therapy is one of major therapeutic tools in cancer treatment. Nevertheless, γ-IR therapy failed due to occurrence of metastasis, which constitutes a significant obstacle in cancer treatment. The main aim of this investigation was to construct animal model which present metastasis during radiotherapy in a mouse systemin vivoand establishes the molecular mechanisms involved.Materials and methodsThe C6L transfectant cell line expressing firefly luciferase (fLuc) was treated with γ-IR, followed by immunoblotting, zymography and invasion assayin vitro.We additionally employed the C6L transfectant cell line to construct xenografts in nude mice, which were irradiated with γ-IR. Irradiated xenograft-containing mice were analyzed via survival curves, measurement of tumor size, and bioluminescence imagingin vivoandex vivo. Metastatic lesions in organs of mice were further assessed using RT-PCR, H & E staining and immunohistochemistry.Resultsγ-IR treatment of C6L cells induced epithelial-mesenchymal transition (EMT) and increased cell invasion. In irradiated xenograft-containing mice, tumor sizes were decreased dramatically and survival rates extended. Almost all non-irradiated xenograft-containing control mice had died within 4 weeks. However, we also observed luminescence signals in about 22.5% of γ-IR-treated mice. Intestines or lungs of mice displaying luminescence signals contained several lesions, which expressed the fLuc gene and presented histological features of cancer tissues as well as expression of EMT markers.ConclusionsThese findings collectively indicate that occurrences of metastases during γ-IR treatment accompanied induction of EMT markers, including increased MMP activity. Establishment of a murine metastasis model during γ-IR treatment should aid in drug development against cancer metastasis and increase our understanding of the mechanisms underlying the metastatic process.
Effects of larval rearing temperature on immature development and West Nile virus vector competence of Culex tarsalis

Published: September 2012

Abstract

Background
Temperature is known to induce changes in mosquito physiology, development, ecology, and in some species, vector competence for arboviruses. Since colonized mosquitoes are reared under laboratory conditions that can be significantly different from their field counterparts, laboratory vector competence experiments may not accurately reflect natural vector-virus interactions.

Methods
We evaluated the effects of larval rearing temperature on immature development parameters and vector competence of two Culex tarsalis strains for West Nile virus (WNV).

Results
Rearing temperature had a significant effect on mosquito developmental parameters, including shorter time to pupation and emergence and smaller female body size as temperature increased. However, infection, dissemination, and transmission rates for WNV at 5, 7, and 14 days post infectious feeding were not consistently affected.

Conclusions
These results suggest that varying constant larval rearing temperature does not significantly affect laboratory estimates of vector competence for WNV in Culex tarsalis mosquitoes.
Matrilin-3 Induction of IL-1 receptor antagonist Is required for up-regulating collagen II and aggrecan and down-regulating ADAMTS-5 gene expression

Abstract
Introduction
Deletion or mutation of the gene encoding the cartilage extracellular matrix (ECM) protein matrilin-3 (MATN3) results in the early onset of osteoarthritis (OA), suggesting chondroprotective properties of MATN3. To understand the mechanisms underlying these properties, we determined the effects of MATN3 protein on the expression of several key anabolic and catabolic genes involved in chondrocyte homeostasis, and the dependence of such regulation on the anti-inflammatory cytokine: IL-1 receptor antagonist (IL-1Ra).

Methods
The effects of recombinant human (rh) MATN3 protein were examined in C28/I2 immortalized human chondrocytes, primary human chondrocytes (PHCs), and primary mouse chondrocytes (PMCs). Messenger RNA levels of IL-1Ra, COL2A1, ACAN, MMP-13, and ADAMTS-4 and -5 were determined using real-time RT-PCR. Knocking down IL-1Ra was achieved by siRNA gene silencing. IL-1Ra protein levels were quantified by ELISA and the Bio-Plex Suspension Array System. COL2A1 protein level was quantified using Western blot analysis. Statistic analysis was done using the two-tailed t-test or one-way ANOVA.

Results
rhMATN3 protein induced gene expression of IL-1Ra in C28/I2 cells, PHCs, and PMCs in a dose- and time-dependent manner. Treatment of C28/I2 cells and PHCs with MATN3 protein stimulated gene expression of COL2A1 and ACAN. Conversely, mRNA levels of COL2A1 and ACAN were decreased in MATN3 KO mice. MATN3 protein treatment inhibited IL-1β-induced MMP-13, ADAMTS-4 and ADAMTS-5 in C28/I2 cells and PHCs. Knocking down IL-1Ra abolished the MATN3-mediated stimulation of COL2A1 and ACAN and inhibition of ADAMTS-5, but had no effect on MATN3 inhibition of MMP-13 mRNA.

Conclusion
Our findings point to a novel regulatory role of MATN3 in cartilage homeostasis due to its capacity to induce IL-1Ra, to upregulate gene expression of the major cartilage matrix components, and to downregulate the expression of OA-associated matrix-degrading proteinases in chondrocytes. The chondroprotective properties of endogenous MATN3 depend partly on its induction of IL-1Ra. Our findings raise a possibility to use rhMATN3 protein for anti-inflammatory and chondroprotective therapy.

Purpose In acute myeloid leukemia (AML), initial treatment response by morphologic analysis of bone marrow predicts long-term outcome. Response can now be assessed by minimal residual disease (MRD) monitoring with flow cytometry or polymerase chain reaction (PCR). We determined the relation among the results of these approaches and their prognostic value. Patients and Methods In the multicenter AML02 study, follow-up bone marrow samples from 203 children and adolescents with newly diagnosed AML were examined by flow cytometry (n = 1,514), morphology (n = 1,382), and PCR amplification of fusion transcripts (n = 508). Results were correlated with treatment outcome. Results Among 1,215 samples with less than 5% leukemic myeloblasts by morphology, 100 (8.2%) were MRD positive (≥ 0.1%) by flow cytometry, whereas 96 (57.5%) of the 167 samples with ≥ 5% blasts were MRD negative. Virtually all (308 of 311; 99.0%) MRD-negative samples by PCR were also MRD negative by flow cytometry. However, only 19 (9.6%) of the 197 PCR-positive samples were flow cytometry positive, with analyses of AML1-ETO and CBFβ-MYH11 accounting for most discrepancies, whereas eight of 13 MLL-positive samples had detectable MRD by flow cytometry. MRD by flow cytometry after induction 1 or 2 predicted lower event-free survival and higher relapse rate (P < .001) and was an independent prognostic factor in a multivariable analysis; prediction was not improved by morphologic information or molecular findings. Conclusion In childhood AML, morphologic assessment of treatment response has limited value if MRD is measured by flow cytometry. MLL fusion transcripts can provide prognostic information in some patients, whereas monitoring of AML1-ETO and CBFβ-MYH11 transcripts is largely uninformative.

Purpose The Janus kinase 2/signal transducers and activators of transcription (JAK2/STAT) pathway plays an important role in the pathogenesis of hematologic malignancies. We conducted a phase I dose-finding and pharmacokinetic/pharmacodynamic study of SB1518, a potent JAK2 inhibitor, in patients with relapsed lymphoma. Patients and Methods Patients with relapsed or refractory Hodgkin or non-Hodgkin lymphoma of any type except Burkitt's or CNS lymphoma were enrolled. Patient cohorts received escalating doses of SB1518 orally once daily for 28-day cycles. Response was evaluated after 8 weeks. Results Thirty-four patients received doses of 100 to 600 mg/d. The maximum tolerated dose was not reached. Treatment was well tolerated, with mostly grade 1 and 2 toxicities. Gastrointestinal toxicities were the most common treatment-related events. Cytopenias were infrequent and modest. Pharmacologically active concentrations were achieved at all doses. Dose-related linear increases in area under the concentration–time curve were seen on day 1, with no significant accumulation on day 15. Mean terminal half-life was 1 to 4 days, and mean time to peak concentration ranged from 5 to 9 hours. SB1518 inhibited JAK2 signaling at 4 hours postdose at all levels. Increases in fms-like tyrosine kinase-3 (FLT-3) ligand, reflecting FLT-3 inhibition, were seen in most patients. There were three partial responses (≥ 300 mg/d) and 15 patients with stable disease (SD), with most responses lasting longer than 2 months. Seven of 13 SDs had tumor reductions of 4% to 46%. Conclusion SB1518 has encouraging activity in relapsed lymphoma, providing the first proof-of-principle of the potential therapeutic value of targeting the JAK/STAT pathway in lymphoma in the clinical setting.

Purpose To compare the efficacy of cediranib (a vascular endothelial growth factor receptor tyrosine kinase inhibitor [VEGFR TKI]) with that of bevacizumab (anti–VEGF-A monoclonal antibody) in combination with chemotherapy as first-line treatment for advanced metastatic colorectal cancer (mCRC). Patients and Methods HORIZON III [Cediranib Plus FOLFOX6 Versus Bevacizumab Plus FOLFOX6 in Patients With Untreated Metastatic Colorectal Cancer] had an adaptive phase II/III design. Patients randomly assigned 1:1:1 received mFOLFOX6 [oxaliplatin 85 mg/m2 and leucovorin 400 mg/m2 intravenously followed by fluorouracil 400 mg/m2 intravenously on day 1 and then continuous infusion of 2,400 mg/m2 over the next 46 hours every 2 weeks] with cediranib (20 or 30 mg per day) or bevacizumab (5 mg/kg every 14 days). An independent end-of-phase II analysis concluded that mFOLFOX6/cediranib 20 mg met predefined criteria for continuation; subsequent patients received mFOLFOX6/cediranib 20 mg or mFOLFOX6/bevacizumab (randomly assigned 1:1). The primary objective was to compare progression-free survival (PFS). Results In all, 1,422 patients received mFOLFOX6/cediranib 20 mg (n = 709) or mFOLFOX6/bevacizumab (n = 713). Primary analysis revealed no significant difference between arms for PFS (hazard ratio [HR], 1.10; 95% CI, 0.97 to 1.25; P = .119), overall survival (OS; HR, 0.95; 95% CI, 0.82 to 1.10; P = .541), or overall response rate (46.3% v 47.3%). Median PFS and OS were 9.9 and 22.8 months for mFOLFOX6/cediranib and 10.3 and 21.3 months for mFOLFOX6/bevacizumab. The PFS upper 95% CI was outside the predefined noninferiority limit (HR < 1.2). Common adverse events with more than 5% incidence in the cediranib arm included diarrhea, neutropenia, and hypertension. Cediranib-treated patients completed fewer chemotherapy cycles than bevacizumab-treated patients (median 10 v 12 cycles). Patient-reported outcomes (PROs) were significantly less favorable in cediranib-treated versus bevacizumab-treated patients (P < .001). Conclusion Cediranib activity, in terms of PFS and OS, was comparable to that of bevacizumab when added to mFOLFOX6; however, the predefined boundary for PFS noninferiority was not met. The cediranib safety profile was consistent with previous studies but led to less favorable PROs compared with bevacizumab. Investigation of oral TKIs in CRC continues.

Purpose Cediranib is a highly potent inhibitor of vascular endothelial growth factor (VEGF) signaling with activity against all three VEGF receptors. HORIZON II [Cediranib (AZD2171, RECENTIN) in Addition to Chemotherapy Versus Placebo Plus Chemotherapy in Patients With Untreated Metastatic Colorectal Cancer] assessed infusional fluorouracil, leucovorin, and oxaliplatin/capecitabine and oxaliplatin (FOLFOX/CAPOX) with or without cediranib in patients with previously untreated metastatic colorectal cancer (mCRC). Patients and Methods Eligible patients were initially randomly assigned 1:1:1 to receive cediranib (20 or 30 mg per day) or placebo plus FOLFOX/CAPOX. In an early analysis of this and two other cediranib studies (HORIZON I [Cediranib Plus FOLFOX6 Versus Bevacizumab Plus FOLFOX6 in Patients With Previously Treated Metastatic Colorectal Cancer] and HORIZON III [Cediranib Plus FOLFOX6 Versus Bevacizumab Plus FOLFOX6 in Patients With Untreated Metastatic Colorectal Cancer]), the 20-mg dose met the predefined criteria for continuation. Subsequent patients were randomly assigned 2:1 to the cediranib 20 mg or placebo arms. Progression-free survival (PFS) and overall survival (OS) were coprimary end points. Results In all, 860 patients received cediranib 20 mg (n = 502) or placebo (n = 358). The addition of cediranib to FOLFOX/CAPOX resulted in PFS prolongation (hazard ratio [HR], 0.84; 95% CI, 0.73 to 0.98; P = .0121; median PFS, 8.6 months for cediranib v 8.3 months for placebo) but had no impact on OS (HR, 0.94; 95% CI, 0.79 to 1.12; P = .5707; median OS, 19.7 months for cediranib v 18.9 months for placebo). There were no significant differences in the secondary end points of objective response rate, duration of response, or liver resection rate. Median chemotherapy dose-intensity was decreased by approximately 10% in patients treated with cediranib. Adverse events (AEs) associated with cediranib were manageable. Conclusion Addition of cediranib 20 mg to FOLFOX/CAPOX resulted in a modest PFS prolongation, but no significant difference in OS. The cediranib AE profile was consistent with those from previous studies. Because of the lack of improvement in OS, cediranib plus an oxaliplatin-based regimen cannot be recommended as a treatment for patients with mCRC.

Purpose To compare the efficacy of aflibercept (ziv-aflibercept), a recombinant human fusion protein targeting the vascular endothelial growth factor (VEGF) pathway, with or without docetaxel in platinum-pretreated patients with advanced or metastatic nonsquamous non–small-cell lung cancer. Patients and Methods In this international, double-blind, placebo-controlled phase III trial, 913 patients were randomly assigned to (ziv-)aflibercept 6 mg/kg intravenous (IV; n = 456) or IV placebo (n = 457), both administered every 3 weeks and in combination with docetaxel 75 mg/m2. The primary end point was overall survival (OS). Other efficacy outcomes, safety, and immunogenicity were also assessed. Results Patient characteristics were balanced between arms; 12.3% of patients had received prior bevacizumab. (Ziv-)Aflibercept did not improve OS (hazard ratio [HR], 1.01; 95% CI, 0.87 to 1.17; stratified log-rank P = .90). The median OS was 10.1 months (95% CI, 9.2 to 11.6 months) for (ziv-)aflibercept and 10.4 months (95% CI, 9.2 to 11.9 months) for placebo. In exploratory analyses, median progression-free survival was 5.2 months (95% CI, 4.4 to 5.6 months) for (ziv-)aflibercept versus 4.1 months (95% CI, 3.5 to 4.3 months) for placebo (HR, 0.82; 95% CI, 0.72 to 0.94; P = .0035); overall response rate was 23.3% of evaluable patients (95% CI, 19.1% to 27.4%) in the (ziv-)aflibercept arm versus 8.9% (95% CI, 6.1% to 11.6%; P < .001) in the placebo arm. Grade ≥ 3 adverse events occurring more frequently in the (ziv-)aflibercept arm versus the placebo arm were neutropenia (28.0% v 21.1%, respectively), fatigue (11.1% v 4.2%, respectively), stomatitis (8.8% v 0.7%, respectively), and hypertension (7.3% v 0.9%, respectively). Conclusion The addition of (ziv-)aflibercept to standard docetaxel therapy did not improve OS. In exploratory analyses, secondary efficacy end points did seem to be improved in the (ziv-)aflibercept arm. The study regimen was associated with increased toxicities, consistent with known anti-VEGF and chemotherapy-induced events.
Hardware Implementation and Steady-State Analysis of ZVS-PWM Cuk Converter Based MPPT for Solar PV Module

Published: September 2012

Abstract
The main objective of this paper is to design and implement a ZVS-PWM Cuk converter to extract maximum power from solar PV module which uses Adaptive Perturb and Observer (APAO) algorithm. ZVS-PWM cuk converter is the interface between the solar PV panel and load. In order to improve electromagnetic compatibility and to reduce the switching losses across the switches, the soft switching (ZVS) has been implemented for Cuk converter, resulting in high converter conversion efficiency with less EMI at high-frequency operation. The harmonic content that each of the converter circuit produces is examined using FFT analysis. The implemented adaptive PAO algorithm improves the steady state stability and dynamic response when compared to the conventional PAO method. This algorithm is simulated using MATLAB/Simulink and implemented using ATMEGA16 micro controller. Hardware validation is carried out for the converter with the solar PV panel with rating of 37W, and operating at 25 kHz.
Compulsion to Rule in Plato’s Republic
Authors: Buckels Christopher 
Published: September 2012

Abstract
Three problems threaten any account of philosophical rule in the Republic. First, Socrates is supposed to show that acting justly is always beneficial, but instead he extols the benefits of having a just soul. He leaves little reason to believe practical justice and psychic justice are connected and thus to believe that philosophers will act justly. In response to this problem, I show that just acts produce just souls. Since philosophers want to have just souls, they will act justly. Second, Socrates’ alleged aim is to demonstrate that justice is beneficial, but philosophers, who have to give up a life of philosophy to rule, actually appear to be harmed by ruling. I explain that, since the founders of the city justly command them to rule, philosophers cannot, in fact, obtain a better life, and so ruling does not harm them. Third, it seems incongruous that philosophers, who should, as just people, jump at the opportunity to rule Kallipolis, must be compelled to rule. I show that Plato carefully constructs an educational system that produces rulers who do not want to rule, since such rulers alone will rule best.
