Abstract
Objective To evaluate the efficacy of earlier oocyte retrieval in IVF patients with a premature LH surge on hCG day. Methods One hundred forty IVF patients (164 cycles) with premature LH surge on hCG day were included, retrospectively. We divided them into 2 study groups: LH surge with timed ovum pick-up (OPU) 36 hours after hCG injection (group B, 129 premature cycles), and LH surge with earlier OPU within 36 hours after hCG injection (group C, 35 cycles). Control groups were tubal factor infertility without premature LH surge (group A, 143 cycles). Results The mean age (year) was statistically higher in group C than in groups A or B (38.2±5.4 vs. 36.2±4.2 vs. 36.8±4.9, respectively; p=0.012). The serum LH levels (mIU/mL) on hCG day were significantly higher in group B and C than in group A (22.7±14.9 vs. 30.3±15.9 vs. 3.2±2.9, respectively; p>0.001). Among groups A, B, and C, 4.9%, 31.7%, and 51.4% of the cycles, respectively, had no oocytes, and the overall rates of cycle cancellation (OPU cancellation, no oocyte, or no embryos transferrable) were 15.4%, 65.9%, and 74.3%, respectively. The fertilization rate (%) was significantly higher in group B than in group C (73.2±38.9 vs. 47.8±42.9, p=0.024). The clinical pregnancy rate was significantly higher in group C than in groups A and B (44.4% vs. 27.3% vs. 9.1%, respectively, p=0.021). However, the miscarriage rate was also higher in group C than in group B (22% vs. 0%, respectively, p=0.026). Conclusion Earlier OPU may not be effective in reducing the risk of cycle cancellation in patients with premature LH surge on hCG day. A larger scale study will be required to reveal the effectiveness of earlier ovum retrieval with premature LH surge.

Abstract
Self-renewal and pluripotency are hallmark properties of pluripotent stem cells, including embryonic stem cells (ESCs) and iPS cells. Previous studies revealed the ESC-specific core transcription circuitry and showed that these core factors (e.g., Oct3/4, Sox2, and Nanog) regulate not only self-renewal but also pluripotent differentiation. However, it remains elusive how these two cell states are regulated and balanced during in vitro replication and differentiation. Here, we report that the transcription elongation factor Tcea3 is highly enriched in mouse ESCs (mESCs) and plays important roles in regulating the differentiation. Strikingly, altering Tcea3 expression in mESCs did not affect self-renewal under nondifferentiating condition; however, upon exposure to differentiating cues, its overexpression impaired in vitro differentiation capacity, and its knockdown biased differentiation toward mesodermal and endodermal fates. Furthermore, we identified Lefty1 as a downstream target of Tcea3 and showed that the Tcea3-Lefty1-Nodal-Smad2 pathway is an innate program critically regulating cell fate choices between self-replication and differentiation commitment. Together, we propose that Tcea3 critically regulates pluripotent differentiation of mESCs as a molecular rheostat of Nodal-Smad2/3 signaling.

Abstract
OBJECTIVE To assess the properties of adrenal lesions with and without known primary cancer and investigate predictors for differential diagnosis between benign and malignant adrenal enlargement. METHODS This retrospective study used fluorine-18 fludeoxyglucose positron emission tomography (PET)/CT in 325 patients with adrenal lesions (229 with known primary cancer and 96 without primary cancer). Age, sex, the presence of right and left masses, nodules or hyperplasia, unenhanced attenuation, maximum standardised uptake value (SUVmax) ratio, and the presence of metastasis in other body parts and locations of the primary cancer were assessed. Univariate and multivariate analyses were used to assess variables associated with risk of adrenal metastasis. RESULTS Patients with adrenal metastasis vs those without had a higher frequency of primary lung cancer (52.3% vs 30.7%) but a lower frequency of gastrointestinal cancer (7.9% vs 16.6%). The frequency of other abnormalities, including adenoma and hyperplasia, was similar between patients with and without known primary cancer. A higher proportion of patients with adrenal metastasis regardless of primary cancer site were younger, had a nodule or a mass, had an unenhanced attenuation of >10 HU, had an SUVmax ratio of >2.5, and had metastasis in other body parts. Analysis found independent associations of age, unenhanced attenuation of >10 HU, SUVmax ratio of >2.5 and the presence of metastasis in other body parts with adrenal metastasis. The combination of the four variables was strongly associated with adrenal metastasis. CONCLUSION PET/CT was useful in characterising adrenal lesions as benign or malignant and helpful in identifying adrenal metastasis and cancer severity. ADVANCES IN KNOWLEDGE PET/CT can help in the differential diagnosis between benign and malignant adrenal enlargement.

Abstract
The upregulation of dopaminergic neuronal differentiation is necessary for stem cell therapy in Parkinson's disease (PD). In this study, neuronal differentiation efficiency increased by more than 2 times in P19 embryonic stem cells (ESCs) induced by N-acetylcysteine (NAC) and retinoic acid (RA) as compared to RA alone, with suppressed glial differentiation. The majority of NAC-treated stem cells grafted into brains of PD mice differentiated into dopaminergic neurons and persisted well for 6 weeks. Parkinsonism was also greatly improved after grafting NAC-treated cells in comparison to cells treated with only RA. Our results strongly suggest that NAC treatment may be an effective strategy for generating stem cells fated to become dopaminergic neurons for PD clinical therapy.

Abstract
In Korea, anemones (Anemone coronaria L.) are mostly grown during winter, in polyethylene tunnels that may have high humidity and poor ventilation, to meet the high demand of cut flowers in February and March for school ceremonies. During the winter of 2011 to 2012, symptoms typical of Sclerotinia stem rot were observed in commercial crops of anemone (cv. Rosso Mistral Plus) in Hwaseong City, Korea. About 40% of anemones withered or died before harvest due to the disease, causing considerable economic losses. In one farmer's polyethylene tunnel with a good ventilation system in Icheon City, Korea, less than 1% of the anemones showed Sclerotinia stem rot during the same season. Symptoms included stem necrosis and withering of leaves, followed by crown rot and wilt a few days afterward. White cottony growth of the fungus was observed on dead plants and the nearby soil surface, especially under high relative humidity. Black sclerotia 2 to 7 mm in diameter developed in the mycelium. Isolations from surface-disinfested stem pieces onto potato dextrose agar (PDA) consistently yielded white, fluffy colonies. Two-week-old colonies produced plentiful numbers of sclerotia on PDA. The isolated fungus was morphologically identified as Sclerotinia sclerotiorum (Lib.) de Bary (1,3). Voucher specimens (n = 4) were deposited in the Korea University herbarium (KUS). Two isolates were deposited in the Korean Agricultural Culture Collection with accession numbers KACC46708 (ex KUS-F26433) and KACC46834 (ex KUS-F26437), respectively. Fungal DNA was extracted with a DNeasy Plant Mini DNA Extraction Kit (Qiagen Inc., Valencia, CA). The complete internal transcribed spacer (ITS) region of rDNA was amplified with the primers ITS1/ITS4 (4) and sequenced using an ABI Prism 337 automatic DNA sequencer (Applied Biosystems, Foster, CA). The resulting sequences of 501 bp were deposited in GenBank (Accession Nos. KC412065 and KC412066). A BLAST search revealed that sequences of the two Korean isolates showed 100% identity with those of S. sclerotiorum (e.g., GenBank Accession No. JN012606). A pathogenicity test was achieved by placing agar segments (9 mm2) from a 7-day-old culture grown on PDA on the stems of healthy anemones (cv. Rosso Mistral Plus) near the soil line. Three plants inoculated with agar blocks served as controls. Plants were maintained in a greenhouse at 16 to 20°C and relative humidity >90%. After 2 days, all inoculated stems became discolored, soft, watery, and covered with white mycelia, whereas control plants remained symptomless. S. sclerotiorum was consistently reisolated from the symptomatic tissue, fulfilling Koch's postulates. Sclerotinia stem rot of anemones caused by S. sclerotiorum has previously been recorded from the United States and New Zealand (2), and to our knowledge, this is the first report of S. sclerotiorum on anemone in Korea. According to our observations in damaged plots, low temperature, high humidity, poor ventilation, and continuous cultivation would accelerate the incidence of Sclerotinia stem rot in polyethylene tunnel cultivation systems in Korea.

Abstract
Purpose We investigated the clinical outcome of bone marrow (BM) involvement in patients with diffuse large B-cell lymphoma (DLBCL) who received rituximab-based therapy. Materials and Methods A total of 567 consecutive patients with newly diagnosed DLBCL treated with rituximab-CHOP (RCHOP) between November 2001 and March 2010 were included in the current study. All of the patients underwent a BM study at the initial staging and the clinical characteristics and prognosis of these patients with or without BM involvement were analyzed retrospectively. Results The total cohort included 567 patients. The overall incidence of BM involvement was 8.5%. With a median follow-up duration of 33.2 months (range, 0.1 to 80.7 months) for patients who were alive at the last follow-up, the five-year overall survival (OS) and event-free survival (EFS) rate in patients without BM involvement (76.3% and 67.5%, p<0.001) was statistically higher than that in patients with BM involvement (44.3% and 40.1%, p<0.001). In multivariate analysis, among total patients, BM involvement showed a significant association with OS and EFS. In univariate and multivariate analyses, even among stage IV patients, a significant association with worse EFS was observed in the BM involvement group. Conclusion BM involvement at diagnosis affected the survival of patients with DLBCL who received RCHOP. Although use of RCHOP can result in significant improvement of the therapeutic effect of DLBCL, BM involvement is still a negative prognostic factor of DLBCL patients in the era of rituximab.

Abstract
BACKGROUND Both palmoplantar pustulosis (PPP) and pompholyx are clinically characterized by acute eruptions of vesicles or pustules on the palms or soles. OBJECTIVES This study aims to compare the expression of certain inflammatory mediator genes and proteins between patients with PPP and pompholyx using skin tissue samples. METHODS Skin biopsies obtained from lesional skin from patients with PPP (n = 7) and pompholyx (n = 5) were analysed by quantitative RT-PCR to measure the mRNA levels of nine genes, including IL-4, IL-8, IL-9, IL-17, IL-22, IFN-γ, CCL-20, granzyme and perforin. For immunohistochemical analysis, 34 paraffin-embedded skin specimens (PPP, n = 22; pompholyx, n = 12) were stained with anti-IL-8, IL-17A, IL-22 and granzyme B antibodies. RESULTS Of genes analysed, IL-8 and IL-17A mRNA expression levels were significantly higher in the PPP group than the pompholyx group (P = 0.012 in both), whereas the mRNA expression of granzyme B was significantly higher in pompholyx when compared with PPP (P = 0.004). Regarding the IL-17A immunohistochemical staining, tissue from the PPP lesions contained significantly more IL-17A(+) cells in both the epidermis and papillary dermis when compared with pompholyx (P < 0.001 and P = 0.019 respectively). Moreover, the intensity of the IL-8 immunoreactivity was also greater in the PPP skin lesions than the pompholyx tissue (P < 0.001). CONCLUSIONS IL-8 and IL-17A, both are increased in PPP tissue, may represent important immunologic mediators that help to differentiate this clinical entity from pompholyx. This study may provide useful clues in distinguishing PPP from pompholyx, as well as helping to understand the pathogeneses of these two diseases.

Abstract
Highly efficient inverted-type red-emitting hybrid polymeric light-emitting diodes (HyPLEDs) were successfully demonstrated via Förster resonance energy transfer (FRET) and interfacial engineering of metal oxide with a cationic conjugated polyelectrolyte (CPE). Similarly structured green- and red-emissive polyfluorene copolymers, F8BT and F8TBT, were homogeneously blended as a FRET donor (host) and acceptor (dopant). A cationic polyfluorene-based CPE was also used as an interfacial layer for optimizing the charge injection/transport and improving the contact problem between the hydrophilic ZnO and hydrophobic polymer layer. A long Förster radius (R0 = 5.32 nm) and high FRET efficiency (~80%) was calculated due to the almost-perfect spectral overlap between the emission of F8BT and the absorption of F8TBT. A HyPLED containing 2 wt % F8TBT showed a pure red emission (λmax = 640 nm) with a CIE coordinate of (0.62, 0.38), a maximum luminance of 26 400 cd/m(2) (at 12.8 V), a luminous efficiency of 7.14 cd/A (at 12.8 V), and a power efficiency of 1.75 lm/W (at 12.8 V). Our FRET-based HyPLED realized the one of the highest luminous efficiency values for pure red-emitting fluorescent polymeric light-emitting diodes reported so far.

Abstract
A facile method for increasing the reaction rate of dye adsorption, which is the most time-consuming step in the production of dye-sensitized solar cells (DSSCs), was developed. Treatment of a TiO2 photoanode with aqueous nitric acid solution (pH 1) remarkably reduced the reaction time required to anchor a carboxylate anion of the dye onto the TiO2 nanoparticle surface. After optimization of the reaction conditions, the dye adsorption process became 18 times faster than that of the conventional adsorption method. We studied the influence of the nitric acid treatment on the properties of TiO2 nanostructures, binding modes of the dye, and adsorption kinetics, and found that the reaction rate improved via the synergistic effects of the following: (1) electrostatic attraction between the positively charged TiO2 surface and ruthenium anion increases the collision frequency between the adsorbent and the anchoring group of the dye; (2) the weak anchoring affinity of NO3(-) in nitric acid with metal oxides enables the rapid coordination of an anionic dye with the metal oxide; and (3) sufficient acidity of the nitric acid solution effectively increases the positive charge density on the TiO2 surface without degrading or transforming the TiO2 nanostructure. These results demonstrate the developed method is effective for reducing the overall fabrication time without sacrificing the performance and long-term stability of DSSCs.

Abstract
An interparticle binding agent, or nanoglue, was synthesized by a sol-gel process, which facilitated the preparation of well-interconnected TiO2 electrodes at low-temperatures for plastic dye-sensitized solar cells. The viscosity of the nanoglue-based pastes was seven times higher than that obtained in pastes without any nanoglue. The increased viscosity was sufficiently high enough for coating thick films to fabricate TiO2 electrodes. The structural and photovoltaic properties of the films were extensively investigated by varying the amounts of nanoglue. A reduced pore size and greatly enhanced surface area were observed in the nanoglue-based films. Improved interparticle connectivity, resulting in faster electron transport, was confirmed by photocurrent transient spectroscopy and electrochemical impedance measurements of the nanoglue-based films. The electron diffusion length and charge collection efficiency were also enhanced in these nanoglue-based films. A maximum conversion efficiency of 5.43% was achieved in films containing 20 wt% nanoglue fabricated on a plastic substrate under one-sun illumination, even without any additional treatment.

Abstract
This study was conducted to examine if fluoxetine, a selective 5-hydroxytryptamine (5-HT) reuptake inhibitor, would reverse adverse behavioral effects of neonatal maternal separation in female rats. Sprague-Dawley pups were separated from dam daily for 3h during postnatal day (PND) 1-14 (maternal separation; MS) or left undisturbed (non-handled; NH). Female NH and MS pups received intraperitoneal injection of fluoxetine (10mg/kg) or vehicle daily from PND 35 until the end of the whole experimental period. Rats were either subjected to behavioral tests during PND 44-54, or sacrificed for neurochemical analyses during PND 43-45. Daily food intake and weight gain of both NH and MS pups were suppressed by fluoxetine, with greater effects in MS pups. MS experience increased immobility and decrease swimming in forced swim test. Swimming was increased, although immobility was not significantly decreased, in MS females by adolescence fluoxetine. However, adolescence fluoxetine increased immobility during forced swim test and decreased time spent in open arms during elevated plus maze test in NH females. Fluoxetine normalized MS-induced decrease of the raphe 5-HT levels and increased 5-HT metabolism in the hippocampus in MS females, and increased the hypothalamic 5-HT both in NH and MS. Fluoxetine decreased the raphe 5-HT and increased the plasma corticosterone in NH females. Results suggest that decreased 5-HTergic activity in the raphe nucleus is implicated in the pathophysiology of depression-like behaviors, and increased 5-HTergic activities in the raphe-hippocampus axis may be a part of anti-depressant efficacy of fluoxetine, in MS females. Also, an extra-hypothalamic 5-HTergic activity may contribute to the increased anorectic efficacy of fluoxetine in MS females. Additionally, decreased 5-HT in the raphe and elevated plasma corticosterone may be related with fluoxetine-induced depression- and/or anxiety-like behaviors in NH females.

Abstract
For the practical application of dye-sensitized solar cells (DSSCs), it is important to replace the conventional organic solvents based electrolyte with environmentally friendly and stable ones, due to the toxicity and leakage problems. Here we report a noble water-based thixotropic polymer gel electrolyte containing xanthan gum, which satisfies both the environmentally friendliness and stability against leakage and water intrusion. For application in DSSCs, it was possible to infiltrate the prepared electrolyte into the mesoporous TiO2 electrode at the fluidic state, resulting in sufficient penetration. As a result, this electrolyte exhibited similar conversion efficiency (4.78% at 100 mW cm(-2)) and an enhanced long-term stability compared to a water-based liquid electrolyte. The effects of water on the photovoltaic properties were examined elaborately from the cyclic voltammetry curves and impedance spectra. Despite the positive shift in the conduction band potential of the TiO2 electrode, the open-circuit voltage was enhanced by addition of water in the electrolyte due to the greater positive shift in the I(-)/I3(-) redox potential. However, due to the dye desorption and decreased diffusion coefficient caused by the water content, the short-circuit photocurrent density was reduced. These results will provide great insight into the development of efficient and stable water-based electrolytes.

Abstract
BACKGROUND In this study, the prognostic impact of the presence of the multifocal or multicentric tumor (MMT) and its association with molecular subtypes were investigated. PATIENTS AND METHODS We investigated the breast cancer metastasis and survival in patients with multifocal or multicentric invasive foci in the same breast. The study population includes 2882 patients in the Seoul National University Hospital Breast Care Center (SNUHBCC) dataset and 41 179 patients in Korean Breast Cancer Registry (KBCR) dataset. RESULTS From SNUHBCC dataset, we observed a significant role of MMT in developing distant metastasis and death when the tumors were triple-negative subtype. This subtype-specific prognostic importance of MMT in overall survival was also seen in KBCR dataset (HR, 1.32; 95% CI, 1.02-1.69). In tumors <2 cm, the hazard ratios (HRs) for node metastasis and death were similar along the tumor size change in triple-negative subtype, while other subtypes showed a stepwise increment, suggesting the biologic importance of small invasive foci in this subtype. CONCLUSIONS Our results demonstrate the prognostic importance of MMT in patients with triple-negative breast cancers. Small additional invasive foci in triple-negative breast cancer patients should be considered as clinically relevant tumor deposits.

Abstract
We demonstrate high-performance polymer solar cells using the plasmonic effect of multipositional silica-coated silver nanoparticles. The location of the nanoparticles is critical for increasing light absorption and scattering via enhanced electric field distribution. The device incorporating nanoparticles between the hole transport layer and the active layer achieves a power conversion efficiency of 8.92% with an external quantum efficiency of 81.5%. These device efficiencies are the highest values reported to date for plasmonic polymer solar cells using metal nanoparticles.

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

Abstract
The first measurement of vector-boson production associated with a top quark-antiquark pair in proton-proton collisions at sqrt[s] = 7 TeV is presented. The results are based on a data set corresponding to an integrated luminosity of 5.0 fb(-1), recorded by the CMS detector at the LHC in 2011. The measurement is performed in two independent channels through a trilepton analysis of ttZ events and a same-sign dilepton analysis of ttV (V = W or Z) events. In the trilepton channel a direct measurement of the ttZ cross section σ(ttZ) = 0.28(-0.11)(+0.14) (stat)(-0.03)(+0.06) (syst) pb is obtained. In the dilepton channel a measurement of the ttV cross section yields σ(ttV) = 0.43(-0.15)(+0.17) (stat)(-0.07)(+0.09) (syst) pb. These measurements have a significance, respectively, of 3.3 and 3.0 standard deviations from the background hypotheses and are compatible, within uncertainties, with the corresponding next-to-leading order predictions of 0.137(-0.016)(+0.012) and 0.306(-0.053)(+0.031) pb.

Abstract
Abstract
Ciglitazone is a kind of thiazolidinedione and a potent, selective peroxisome proliferator-activated receptor γ (PPAR γ) ligand and it is active in vivo as an anti-hyperglycemic agent in the murine model. Glucose metabolism plays a key role in the maintenance of energy homeostasis in organisms and changes in cellular glucose uptake rate are found in malignant diseases. Significant increase in glucose consumption can be found in many malignant conditions and research so far has focused on its apoptotic and inhibition of proliferation properties but their role in cell death is unclear. We show that ciglitazone inhibits glucose uptake in ovarian cancer cell through GLUT-1 expression. In this study, we investigated the effect of ciglitazone to GLUT-1 expression and cell proliferation. We further demonstrate that ciglitazone pretreated tumor cell was increased apoptosis dose dependent manner and siGLUT-1 treated tumor cell showed increased apoptosis. Interestingly, not only cancer cell line but also in vivo state, ciglitazone could decrease tumor mass.
Specificity protein (Sp) is highly expressed in tissues of prostate cancer, breast carcinomas and lung cancer when compared to normal tissues or cells. Previous studies showed that Sp1 plays an important role in carcinogenesis and metastasis of several human tumor types by regulating growth-related signal transduction, cell cycle control molecules, apoptosis, oncogenes, tumor suppressor genes. In this study there was no relation with apoptosis and SP1 expression. We demonstreated that ciglitazone inhibit glucose uptake in ovarian cancer cell lines and the relationship between ciglitazone and GLUT-1 in ciglitazone induced cell death.

Abstract
Abstract
OBJECTIVE: Advanced biliary cancer is associated with a poor prognosis due to wide resistance to chemotherapeutic agents. This phase II clinical trial was conducted to determine the efficacy and safety of weekly gemcitabine and liposomal paclitaxel in patients with unresectable of metastatic biliary cancer.
METHODS: The eligibility criteria were patients 1) with pathologically proven biliary cancer, 2) with an ECOG performance status 0 to 2, 3) aged more than 18, 4) with measurable lesions, 5) with adequate hematologic, renal and liver functions, and 6) who provided written informed consent. Each treatment cycle was consisted of gemcitabine 1000 mg/m² and liposomal paclitaxel (Genexol-PM)100 mg/m² on days 1, 8 followed by rest perioid of 14 days. It was repeated until the appearance of disease progression or unacceptable toxicity up to maximal 10 cycles. The primary end point of this study was reponse rate, and secondary end points included toxicity, progression free survival and overall survival.
RESULTS: Forty five patients were enrolled; median age was 63 years; male (n=33) and female (n=12). The median number of cycles administered was 4.0 (range,1-10). Thirty nine patients were assessable for efficacy. Ten partial responses and 18 stable diseases were confirmed. Giving an overall response rate was 25.6% and disease control rate was 71.8% in per-protocol population. The median time to progression and median overall survival was 4.0 (95% CI; 3.17∼4.83) months and 8.13 (95% CI; 4.76∼11.51) months, respectively. MUC4 expression was not significantly correlated with overall survival and progression free survival (p=0.391).
CONCLUSION: Weekly gemcitabine combined with Genexol-PM® appears to be effective against advanced biliary cancers. Further randomized trials are needed to confirm this finding.

ACTA CRYSTALLOGRAPHICA SECTION D: BIOLOGICAL CRYSTALLOGRAPHY 2013; 69:735-46.

Abstract
Maturation of cytochrome c is carried out in the bacterial periplasm, where specialized thiol-disulfide oxidoreductases provide the correct reduction of oxidized apocytochrome c before covalent haem attachment. HP0377 from Helicobacter pylori is a thioredoxin-fold protein that has been implicated as a component of system II for cytochrome c assembly and shows limited sequence similarity to Escherichia coli DsbC, a disulfide-bond isomerase. To better understand the role of HP0377, its crystal structures have been determined in both reduced and partially oxidized states, which are highly similar to each other. Sedimentation-equilibrium experiments indicate that HP0377 is monomeric in solution. HP0377 adopts a thioredoxin fold but shows distinctive variations as in other thioredoxin-like bacterial periplasmic proteins. The active site of HP0377 closely resembles that of E. coli DsbC. A reductase assay suggests that HP0377 may play a role as a reductase in the biogenesis of holocytochrome c553 (HP1227). Binding experiments indicate that it can form a covalent complex with HP0518, a putative L,D-transpeptidase with a catalytic cysteine residue, via a disulfide bond. Furthermore, physicochemical properties of HP0377 and its R86A variant have been determined. These results suggest that HP0377 may perform multiple functions as a reductase in H. pylori.

Abstract
A search for the pair production of a heavy, narrow resonance decaying into two jets has been performed using events collected in sqrt[s] = 7 TeV pp collisions with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 5.0 fb(-1). Events are selected with at least four jets and two dijet combinations with similar dijet mass. No resonances are found in the dijet mass spectrum. The upper limit at 95% confidence level on the product of the resonance pair production cross section, the branching fractions into dijets, and the acceptance varies from 0.22 to 0.005 pb, for resonance masses between 250 and 1200 GeV. Pair-produced colorons decaying into qq are excluded for coloron masses between 250 and 740 GeV.

Abstract
BACKGROUND AND AIM We examined the association of fatty acid (FA) composition in serum phospholipids with the features of metabolic syndrome (MetS) and arterial stiffness. METHODS Korean men (n = 593, 30-79 yrs) were categorized based on the number of MetS risk factors (RFs) and measured for the markers of MetS, serum phospholipid FA composition and brachial-ankle pulse wave velocity (baPWV), an index for the severity of arterial stiffness. RESULTS Insulin resistance (HOMA-IR), baPWV, LDL size, and adiponectin were significantly altered corresponding to the number of MetS RFs. The proportions of total monounsaturated FA, palmitoleic acid (16:1), oleic acid (18:1ω-9) and dihomo-γ-linolenic acid (DGLA, 20:3ω-6) in serum phospholipids, and DGLA/linoleic acid (LA) (20:3ω-6/18:2ω-6), deta9-desaturase activity (D9D-16: 16:1/16:0 and D9D-18: 18:1ω-9/18:0) significantly increased corresponding to the number of MetS RFs, but D5D (20:4ω-6/20:3ω-6) decreased. baPWV positively correlated with HOMA-IR, palmitic acid (16:0), oleic acid, D6D (18:3ω-6/18:2ω-6), DGLA/LA and D9D-18, and negatively with adiponectin, LDL size, LA, docosahexaenoic acid (DHA, 22:6ω-3) and D5D. Multiple stepwise regression models revealed that baPWV was significantly influenced by systolic blood pressure, age, body weight, triglyceride and LA in serum phospholipids (R(2) = 0.378). Interestingly, baPWV (1419 ± 1 cm/s) and MetS (22%) were highest in individuals with lower proportion of LA (< 12.361%) and higher proportion of DGLA (≥ 1.412%) in serum phospholipid FAs. CONCLUSION The features of MetS significantly related to serum phosopholipid FA composition. Particularly, arterial stiffness was associated with LA additively together with DLGA. It may suggest a potential benefit of sufficient amounts of LA in serum or in diet can reduce cardiovascular risk.

Abstract
Auditory fear conditioning is a well-characterized rodent learning model where a neutral auditory cue is paired with an aversive outcome to induce associative fear memory. The storage of long-term auditory fear memory requires long-term potentiation (LTP) in the lateral amygdala and de novo protein synthesis. Although many studies focused on individual proteins have shown their contribution to LTP and fear conditioning, non-biased genome-wide studies have only recently been possible with microarrays, which nevertheless fall short of measuring changes at the level of proteins. Here we employed quantitative proteomics to examine the expression of hundreds of proteins in the lateral amygdala in response to auditory fear conditioning. We found that various proteins previously implicated in LTP, learning and axon/dendrite growth were regulated by fear conditioning. A substantial number of proteins that were regulated by fear conditioning have not yet been studied specifically in learning or synaptic plasticity.
