Prostaglandins Leukot Essent Fatty Acids 2013; 89:47-53. [PMID: 23688707 DOI: 10.1016/j.plefa.2013.04.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2013] [Revised: 04/06/2013] [Accepted: 04/09/2013] [Indexed: 12/23/2022]
Abstract
In sepsis, excessive inflammation may lead to organ injury or a paradoxical immunosuppressed state where the host is unable to clear preexisting infection. Resolution of inflammation is the process which restores tissue homeostasis and ensures that a chronic cycle of infection/inflammation does not occur. Lipoxin A4 (LXA4) is one of a family of lipid mediators with novel inflammation resolution activity. We compared the actions of LXA4 to the stable 15-epi-16-(para-fluorophenoxy)-lipoxin A4 methyl ester (LXA4 analog) in the cecal ligation and puncture (CLP) model of sepsis. Both LXA4 compounds (at 7 μg/kg; i.v.) reduced plasma TNFα and IL-6 concentrations compared to rats given vehicle saline. Neither treatment altered plasma IL-10 compared to CLP given saline, but LXA4 analog, increased plasma IL-10 concentrations compared to rats given LXA4. LXA4 reduced blood bacterial load but the LXA4 analog did not. LXA4 increased 8 day survival and the LXA4 analog did not have a significant effect. To examine possible mechanisms for the differences, we investigated peritoneal leukocyte gene expression of iNOS and macrophage phagocytic ability. Only LXA4 increased the percentage of phagocytic peritoneal macrophages. LXA4 reduced neutrophil gene expression of iNOS compared to CLP rats given vehicle, while the LXA4 analog did not. Our results suggest that at doses which reduced systemic inflammation, only LXA4 inhibited bacterial spread and increased survival. This difference may be due to the shorter-lived compound being able to increase macrophage phagocytosis and reduce neutrophil iNOS expression.

Abstract
Abstract
Polybutadiene-based polyurethane/poly (methyl methacrylateco-glycol dimethacrylate) interpenetrating polymer networks (PU (HTPB)/P(MMA-co-EGDMA)-IPN) was synthesized by simultaneous polymerization. FTIR and dynamic mechanical spectra (DMS) show no apparent chemical bonds between the two component polymers. The results of DMS also demonstrated that the interpenetration of networks exists mainly between P(MMA-co-EGDMA) and the hard segments of PU(HTPB). The results of transmitting electron microscopy (TEM) indicate that when the amounts of P(MMA-co-EGD-MA) are from 20 to 80 wt%, the domain sizes increase from 100 to 200 Å to several microns, and the morphology features vary from the interpenetration of microphase separation structure to the boundary interpenetration of cellular structure. Besides, the IPN has dual phase continuity. With increasing amounts of P(MMA-co-EGDMA), the stress-strain curves indicate that the corresponding IPN materials transform from reinforced rubbers to toughened plastics. The mechanical properties of the full-IPN are far superior to those of the corresponding linear blends, and also higher than those of the corresponding semi-IPN.

Abstract
The interleukin-12B (IL12B) gene encodes the p40 chain of IL-12, a pro-inflammatory cytokine that antagonizes Th2 phenotype and, hence, may have a critical role in the pathogenesis of allergic asthma. In this report, we describe the identification of a novel IL12B promoter polymorphism (T-to-A exchange) at position -536. The IL12B -536AA genotype was significantly associated with asthma in the Chinese populations (P=0.011, odds ratio=2.227). The risk-associated A allele was linked to reduced expression of IL12B mRNA levels and IL12B production in asthmatic patients. Luciferase reporter assay provided evidence that risk-associated A allele reduced the promoter activity of IL12B gene compared with those of the promoter containing the protective T allele. We further observed that decreasing binding effects between the risk alleles A of IL12B and CCAAT/enhancer binding protein alpha (C/EBPα) through A allele sequence mediated streptavidin-conjugated agarose pulldown and biotin-labelled A allele mediated electrophoretic mobility shift assay. We also observed additive effects of the risk alleles of IL12B and decreased mRNA levels of C/EBPα in asthmatic patients. Therefore, we postulated that the presence of -536A allele in IL12B promoter could predispose to the development of allergic asthma.

The use of prophylactic gastroprotective therapy in patients with nonsteroidal anti-inflammatory drug- and aspirin-associated ulcer bleeding: a cross-sectional study.

Abstract
BACKGROUND Poor adherence to gastroprotective agents (GPAs) is common among users of nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin (ASA). There are little data on the utilization of GPAs among NSAID and ASA users complicated by ulcer bleeding. AIM To study the utilization of GPA among NSAID and ASA ulcers before the onset of ulcer bleeding. METHODS We conducted a cross-sectional study to determine the exposure to NSAIDs, ASA, and GPAs within 4 weeks before endoscopically confirmed ulcer bleeding. Sensitivity analysis was performed to study how improving adherence to GPA use would reduce the risk of ulcer bleeding in high-risk users. RESULTS Between 2000 and 2009, 1093 and 2277 patients had NSAID- and ASA-associated ulcer bleeding respectively. The incidence of NSAID-associated ulcer bleeding declined by 40%, whereas that of ASA-associated ulcer bleeding increased by 46%. Thirty-nine per cent of NSAID users and 75% of ASA users belonged to high ulcer risk category. Although GPA prescription rate has increased over time, only 41.6% and 30.6% of high-risk NSAID and ASA users received GPAs before ulcer bleeding respectively. Sensitivity analysis showed that if GPAs could reduce bleeding risk by 50%, improving adherence would prevent up to 35% of ulcer bleeding in high-risk users. CONCLUSIONS A substantial proportion of high-risk NSAID and ASA users had not received prophylaxis with gastroprotective agents before ulcer bleeding. These bleeding episodes may be preventable with better adherence to gastroprotective agent use.

Abstract
Ultrafast laser techniques have revealed extraordinary spin dynamics in magnetic materials that equilibrium descriptions of magnetism cannot explain. Particularly important for future applications is understanding non-equilibrium spin dynamics following laser excitation on the nanoscale, yet the limited spatial resolution of optical laser techniques has impeded such nanoscale studies. Here we present ultrafast diffraction experiments with an X-ray laser that probes the nanoscale spin dynamics following optical laser excitation in the ferrimagnetic alloy GdFeCo, which exhibits macroscopic all-optical switching. Our study reveals that GdFeCo displays nanoscale chemical and magnetic inhomogeneities that affect the spin dynamics. In particular, we observe Gd spin reversal in Gd-rich nanoregions within the first picosecond driven by the non-local transfer of angular momentum from larger adjacent Fe-rich nanoregions. These results suggest that a magnetic material's microstructure can be engineered to control transient laser-excited spins, potentially allowing faster (~ 1 ps) spin reversal than in present technologies.

Abstract
BACKGROUND Prostate cancer (PCa) gene expression marker 1 (PCGEM1), a long noncoding RNA, has drawn increasing attention for its important role in PCa. However, the association between genetic variations in the PCGEM1 gene and risk of PCa has not been investigated yet. METHODS We investigated the effect of two tagging single-nucleotide polymorphism (tSNPs; rs6434568 and rs16834898) in PCGEM1 gene on PCa risk in the Chinese men. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association. RESULTS We found a significantly decreased risk of PCa for rs6434568 AC and AC/AA genotype (adjusted OR=0.76, 95% CI=0.60-0.97 for AC; adjusted OR=0.76, 95% CI=0.61-0.96 for AC/AA), as well as rs16834898 AC and AC/CC genotype (adjusted OR=0.76, 95% CI=0.59-0.97 for AC; adjusted OR=0.79, 95% CI=0.62-0.99 for AC/CC), compared with the CC and AA genotypes, respectively. When we evaluated these two tSNPs together based on the risk alleles (that is, rs6434568 C and rs16834898 A), we found that the combined genotypes with four risk alleles were associated with an increased risk of PCa compared with those carrying 0-3 risk alleles (1.53, 1.19-1.97), and this increased risk was more pronounced among subjects of≤70 years (1.80, 1.24-2.62), Gleason score≥7 (1.68, 1.28-2.22) and PSA level≥20 (1.64, 1.24-2.18). CONCLUSIONS Our results indicated that PCGEM1 polymorphisms may contribute to PCa risk in Chinese men. Additional functional analyses are required to detect the detailed mechanism underlying the observed association.

Abstract
In recent years, many studies have focused on the roles of mesenchymal stem cells (MSCs) due to their contribution to tissue regeneration and tumorigenesis. However, the full profile of the roles of MSCs in gastric diseases has not been established. In this review, we aim to provide an overview on the roles of MSCs on cell lesion and regeneration in gastric diseases, including gastric ulcer, premalignant conditions and cancer. We will also discuss the mechanisms underlying the behaviors of MSCs in these diseases.

Abstract
Background: This phase 2 study evaluated trebananib (AMG 386), an investigational peptide-Fc fusion protein that neutralises the interaction between angiopoietins-1/2 and the Tie2 receptor, plus FOLFIRI as second-line treatment for patients with metastatic colorectal cancer. Methods: Patients had adenocarcinoma of the colon or rectum with progression within 6 months of receiving only one prior fluoropyrimidine/oxaliplatin-based chemotherapy regimen for metastatic disease. All patients received FOLFIRI and were randomised 2 : 1 to also receive intravenous trebananib 10 mg kg−1 once weekly (QW) (Arm A) or placebo QW (Arm B). The primary end point was investigator-assessed progression-free survival (PFS). Results: One hundred and forty-four patients were randomised (Arms A/B, n=95/49). Median PFS in Arms A and B was 3.5 and 5.2 months (hazard ratio (HR) 1.23; 95% CI, 0.81–1.86; P=0.33) and median overall survival (OS) was 11.9 and 8.8 months, respectively (HR 0.90; 95% CI; 0.53–1.54; P=0.70). Objective response rate (ORR) was 14% and 0% in Arms A and B, respectively. Incidence of grade ⩾3 adverse events was similar between treatment arms (Arm A, 61% Arm B, 65%) and included pulmonary embolism (1%/4%), deep vein thrombosis (5%/2%), and hypertension (1%/0%). Conclusion: Administration of trebananib plus FOLFIRI did not prolong PFS compared with placebo plus FOLFIRI. Toxicities were manageable and consistent with those known for FOLFIRI and trebananib.

Abstract
The x-ray intensities made available by x-ray free electron lasers (FEL) open up new x-ray matter interaction channels not accessible with previous sources. We report here on the resonant generation of Kα emission, that is to say the production of copious Kα radiation by tuning the x-ray FEL pulse to photon energies below that of the K edge of a solid aluminum sample. The sequential absorption of multiple photons in the same atom during the 80 fs pulse, with photons creating L-shell holes and then one resonantly exciting a K-shell electron into one of these holes, opens up a channel for the Kα production, as well as the absorption of further photons. We demonstrate rich spectra of such channels, and investigate the emission produced by tuning the FEL energy to the K-L transitions of those highly charged ions that have transition energies below the K edge of the cold material. The spectra are sensitive to x-ray intensity dependent opacity effects, with ions containing L-shell holes readily reabsorbing the Kα radiation.

Abstract
OBJECTIVE MicroRNA-221 (miR-221), which is located on chromosome X, is an oncogenic microRNA that is involved in several human malignancies. This study aimed to characterize the role of miR-221 in the initiation and malignant progression of gastric cancer. METHODS The level of miR-221 expression in 92 pairs of primary gastric tumour tissue and adjacent nontumour tissue was quantified by real-time reverse transcription-polymerase chain reaction. The relationship between the miR-221 level and clinicopathological features was explored. RESULTS MiR-221 was up-regulated in 88% (81/92) of gastric cancer tissue samples compared with their paired adjacent nontumour tissue samples. High expression of miR-221 showed a significant correlation with advanced tumour-node-metastasis stage, local invasion and lymphatic metastasis. Univariate and multivariate Cox proportional hazard regression analyses revealed that miR-221 overexpression was an unfavourable prognostic factor for overall survival in patients with gastric cancer. CONCLUSIONS These findings suggest that miR-221 is a novel prognostic indicator in gastric cancer and may be a potential target for diagnosis and gene therapy.

Abstract
A molecular linkage map of cultivated oat composed of 561 loci has been developed using 71 recombinant inbred lines from a cross between Avena byzantina cv. Kanota and A. sativa cv. Ogle. The loci are mainly restriction fragment length polymorphisms detected by oat cDNA clones from leaf, endosperm, and root tissue, as well as by barley leaf cDNA clones. The loci form 38 linkage groups ranging in size from 0.0 to 122.1 cM (mean, 39 cM) and consist of 2-51 loci each (mean, 14). Twenty-nine loci remain unlinked. The current map size is 1482 cM and the total size, on the basis of the number of unlinked loci, is estimated to be 2932.0 cM. This indicates that this map covers at least 50% of the cultivated oat genome. Comparisons with an A-genome diploid oat map and between linkage groups exhibiting homoeology to each other indicate that several major chromosomal rearrangements exist in cultivated oat. This map provides a tool for marker-assisted selection, quantitative trait loci analyses, and studies of genome organization in oat.

Abstract
The application of Radio Frequency Identification (RFID) sensor networks pervasively to the hospital environment has the potential to improve efficiencies in operational aspects through accurate capture of fine grained data. The sensor nodes generate large amounts of real or near real-time data. Understanding and managing these data in the context of the hospital pose challenges for the middleware which has to connect sensor networks with hospital applications. In this paper we propose an edgeware paradigm of organizing hospital RFID sensor data based on the notion of an event. The event is defined and its properties are discussed. A three layered event representation and reasoning model is developed to map raw sensory information to semantic events in the application domains. A prototype system, called eWellness is build for the test of the local hospital.

Abstract
OBJECTIVES The objective of this study was to review the high-resolution CT (HRCT) findings in patients with pulmonary infection after orthotopic liver transplantation (OLT) and to determine distinguishing findings among the various types of infection. METHODS This study included 453 consecutive liver transplant recipients with pulmonary infection, on whom HRCT of the chest was performed within 24 h of the beginning of symptoms and for whom proven diagnosis had taken place within 1 week of the onset of symptoms. Two radiologists analysed the CT images; final decisions regarding the findings were reached by consensus. RESULTS Bacterial and viral pneumonia made up the bulk of infections (63.4% and 29.4%, respectively), followed by fungal infiltrates (24.5%). Large nodules were most common in patients with fungal pneumonia, having been seen in 38 (54%) of the 70 patients with fungal pneumonia, 22 (10%) of 220 with bacterial pneumonia (p=0.0059) and 6 (8%) of 78 with viral pneumonia (p=0.0011). The halo sign was also more frequent in patients with fungal pneumonia, having been seen in 38 (54%) of the 70 patients with fungal pneumonia, 17 (8%) of 220 with bacterial pneumonia (p=0.0026) and 7 (9%) of 78 with viral pneumonia (p=0.0015). There was no statistically significant difference in the prevalence of the other HRCT patterns including air-space consolidation, ground-glass attenuation and small nodules among bacterial, viral and fungal infections (all p>0.05). CONCLUSION The presence of large nodules with the halo sign is most suggestive of fungal infection after OLT. Other HRCT patterns are not helpful in distinguishing among the various types of infection seen in liver transplant recipients.

Abstract
BACKGROUND Wildtype p53 and Smad4 are important suppressor genes in tumor genesis and development. The mutation in p53 gene is closely related to the early formation of breast cancer. In this research, we try to explore the status of Smad4 in breast cancer cell line MCF7 after knocking down p53. MATERIALS AND METHODS MCF-7 was bought from American Type Culture Collection (ATCC). Cells were cultured in Dulbecco's Modified Eagle Medium (DMEM) with 10% fetal bovine serum (FBS) in incubator containing 5% CO2 at 37°C. In this study we apply to analytical methods such as growth ratio analysis in vitro, immunoblot analysis, flow cytometry for cell cycle analysis, RNA extraction and Real-Time PCR and data analysis. RESULTS The results indicated that specific down regulating of p53 can significantly increase the expression of Smad4 in cancer cell line MCF7 and promote cell apoptosis. In MCF7 cell line p53 gene is negatively related to Smad4 in great extent. CONCLUSIONS In our study, we detect the expression and function of Smad4 by suppressing p53 expression in MCF7, trying to figure out the relationship and signaling pathway between them. In this study, we try to found the affection of p53 on Smad4, so as to induce apoptosis in tumor cell, achieving the goal of targeted cancer prevention and treatment.
