Abstract
In tritrophic 'plants-herbivores-natural enemies' systems, there are relatively few reports concerning the role(s) of kairomones in pupal parasitism. Chouioia cunea Yang (Hymenoptera: Eulophidae), an endoparasitic chalcid wasp, parasitizes pupae of the fall webworm (Hyphantria cunea Drury). The role of host-related kairomones was investigated using electroantennogram (EAG) and behavioral techniques. Chemicals from some host stages (pupae) and host by-products (frass), induced arrestment behavior of female parasitoids, while chemicals from prepupae, were inactive. Gas chromatography-mass spectrometry analysis of volatiles collected from pupae, frass and prepupae using solid-phase microextration revealed seven compounds with carbon chain lengths ranging from C4 to C20. All of the chemicals elicited significant EAG responses in C. cunea. Y-tube olfactometer bioassays demonstrated a significant positive response of mated female C. cunea to 1-dodecene. These data provide a better understanding of the host location mechanisms of pupal parasitoid.

Abstract
We have recently reported that bovine herpesvirus 1 (BoHV-1)-induced overproduction of reactive oxygen species (ROS) partially depends on NADPH oxidases (Noxs). In this study, we found that the decreased levels of main intracellular non-enzymatic antioxidant glutathione (GSH) during BoHV-1 infection also contributed to ROS production. Exogenous GSH administration dramatically inhibited BoHV-1 replication, indicating the critical role of decreased GSH for BoHV-1 replication. Interestingly, GSH synergistically enhanced the antiviral effects of acyclovir (ACV) against BoHV-1 infection in vitro. This study not only illuminates the effect of GSH on BoHV-1 infection but also provides evidence that pharmacological modulation of GSH-mediated ROS production in combination with specific antiviral drugs is a viable therapeutic approach to fighting virus infection.

Abstract
Differentiation of human embryonic stem cells into mesendoderm (ME) is directed by extrinsic signals and intrinsic epigenetic modifications. However, the dynamics of these epigenetic modifications and the mechanisms by which extrinsic signals regulate the epigenetic modifications during the initiation of ME differentiation remain elusive. In this study, we report that levels of histone H3 Lys-27 trimethylation (H3K27me3) decrease during ME initiation, which is essential for subsequent differentiation induced by the combined effects of activin and Wnt signaling. Furthermore, we demonstrate that activin mediates the H3K27me3 decrease via the Smad2-mediated reduction of EZH2 protein level. Our results suggest a two-step process of ME initiation: first, epigenetic priming via removal of H3K27me3 marks and, second, transcription activation. Our findings demonstrate a critical role of H3K27me3 priming and a direct interaction between extrinsic signals and epigenetic modifications during ME initiation.

Abstract
Interleukin (IL)-12 family cytokines play critical roles in autoimmune diseases. Our previous study has shown that IL-23p19 and Epstein-Barr virus-induced 3 (Ebi3) form a new IL-12 family heterodimer, IL-23p19/Ebi3, termed IL-39, and knock-down of p19 or Ebi3 reduced diseases by transferred GL7+ B cells in lupus-prone mice. In the present study, we explore further the possible effect of IL-39 on murine lupus. We found that IL-39 in vitro and in vivo induces differentiation and/or expansion of neutrophils. GL7+ B cells up-regulated neutrophils by secreting IL-39, whereas IL-39-deficient GL7+ B cells lost the capacity to up-regulate neutrophils in lupus-prone mice and homozygous CD19cre (CD19-deficient) mice. Finally, we found that IL-39-induced neutrophils had a positive feedback on IL-39 expression in activated B cells by secreting B cell activation factor (BAFF). Taken together, our results suggest that IL-39 induces differentiation and/or expansion of neutrophils in lupus-prone mice.

Abstract
Oral squamous cell carcinoma (OSCC) is the most common cancer of the head and neck and is associated with a high rate of lymph node metastasis. The initial step in the metastasis and transition of tumors is epithelial-mesenchymal transition (EMT)-induced angiogenesis, which can be mediated by angiopoietin 2 (ANG2), a key regulatory factor in angiogenesis. In the present study, immunohistochemistry and real-time quantitative reverse transcriptase (qRT-PCR) were used to measure the expression of ANG2 in OSCC tissues. Plasmids encoding ANG2 mRNA were used for increased ANG2 expression in the OSCC cell line TCA8113. The short interfering RNA (siRNA)-targeting ANG2 mRNA sequences were used to inhibit ANG2 expression in TCA8113 cells. Subsequently, transwell assays were performed to examine the effects of ANG2 on TCA8113 cell migration and invasion. Furthermore, in vivo assays were performed to assess the effect of ANG2 on tumor growth. Terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assays and immunohistochemistry were used to examine cell apoptosis and angiogenesis in tumor tissues, respectively. Finally, western blot analysis was performed to evaluate tumor formation-related proteins in OSCC tissues. We found that protein expression of ANG2 was remarkably upregulated in OSCC tissues. Overexpression of ANG2 increased the migration and invasion of TCA8113 cells by regulating EMT. Further investigations showed that overexpression of ANG2 increased tumor growth in nude mice, and angiogenesis of OSCC tissues increased in the presence of ANG2 overexpression. Overexpression of ANG2 also reduced cell apoptosis in tumor tissue cells. Finally, we found that overexpression of ANG2 resulted in changes in the expression of tumor formation-related proteins including vimentin, E-cadherin, Bim, PUMA, Bcl-2, Bax, Cyclin D1, PCNA and CD31. Our findings show that ANG2 has an important role in the migration and invasion of OSCC. More importantly, further investigations suggested that overexpression of ANG2 might increase OSCC metastasis by promoting angiogenesis in nude mice. This stimulatory effect could be achieved by inducing abnormal EMT and by reducing apoptosis and increasing proliferation of cells.

Abstract
Anti-inflammation strategy is one of the proposed therapeutic approaches to hepatic fibrosis. IL-17 is critical in inflammation, but the role of IL-17 in liver fibrosis has not yet been elucidated. In this study, we investigate the role of IL-17 on bile duct ligation-induced liver injury and fibrosis in C57BL/6 mice. Animals were sacrificed at designated times, and serum and liver tissues were collected for analysis of liver function and serum IL-6, IL-1β, tumour necrosis factor-alpha (TNF-α) and transforming growth factor-β (TGF-β) levels. IL-17 blockade with anti-IL-17A mAb significantly improved liver function and decreased hepatocellular necrosis, pro-inflammatory cytokines, neutrophils and macrophages influx. Furthermore, CD3 + and CD8 + lymphocytes, neutrophils and macrophages were found to express IL-17, and neutrophils are the principal IL-17-producing cells after BDL-induced liver injury. These data indicated that IL-17 signal contributes to the pathogenesis of cholestatic liver injury and blocked of IL-17 could potentially benefit patients with cholestatic liver disease.

Abstract
We demonstrate the strong coupling of dye molecules to surface plasmon polaritons (SPPs) excited in the Kretschmann geometry and propagating at the interface of silver and dye-doped polymer. The dispersion curve of such a system, studied in the reflectometry experiments, is split into three branches and demonstrates an avoided crossing - the signature of a strong coupling. We have further studied the excitation spectra of the dye emission and found that the positions of the excitation peaks have a good match with the points in the dispersion curve determined by the reflectometry. At the same time, the analysis of the spectra of the plasmon-mediated spontaneous emission, decoupled to the prism and acquired at multiple collection angles, has resulted in a quite different dispersion curve exhibiting a non-trivial splitting into multiple branches. This suggests that the same plasmonic environment couples differently to absorbing and emitting dye molecules.

Abstract
Knowledge of critical care nurses' intravenous fluid bolus therapy (FBT) practice remains underexplored. Using a multi-choice online survey conducted between September and October 2014, we sought to describe the self-reported practice of critical care nurses located in Australia and New Zealand. Two hundred and ninety-five critical care nurses responded to the survey with most practising in adult ICUs. Overall, 0.9% saline solution was the preferred solution for FBT. However, more Australian than New Zealand respondents preferred 'albumin 4%' (31% versus 3.6%, P <0.01) for FBT. In contrast, more New Zealand respondents preferred 'Plasma-Lyte®' (33.3% versus 6.4%, P <0.01). Half of the respondents defined FBT as 250 ml administered as quickly as possible. However, FBT volumes ranged from 100 ml to >1000 ml and administration duration from as quickly as possible to 60 minutes. In response to FBT, almost half of the respondents expected an increase in mean arterial pressure of between 11 to 20 mmHg. Similarly, >40% expected a central venous pressure increase >3 mmHg, >70% expected a urinary output increase of 0.5 to 1.0 ml/kg/hr, and >60% expected a decrease in heart rate of >11 /min. Overall, 0.9% saline remains the most common solution for FBT, but there are significant national differences in the preference for albumin and Plasma-Lyte. A volume of 250 ml defines a fluid bolus, with a range from 100 ml to >1000 ml, and speed of delivery from stat to 60 minutes. Most nurses expect substantial physiological effects with FBT.

Abstract
BACKGROUND AND OBJECTIVE Periodontitis is a severe chronic inflammatory disease and one of the most prevalent non-communicable chronic diseases that affects the majority of the world's adult population. While great efforts have been devoted toward understanding the pathogenesis of periodontitis, there remains a pressing need for developing potent therapeutic strategies for targeting this dreadful disease. In this study, we utilized adeno-associated virus (AAV) expressing cathepsin K (Ctsk) small hairpin (sh)RNA (AAV-sh-Ctsk) to silence Ctsk in vivo and subsequently evaluated its impact in periodontitis as a potential therapeutic strategy for this disease. MATERIAL AND METHODS We used a known mouse model of periodontitis, in which wild-type BALB/cJ mice were infected with Porphyromonas gingivalis W50 in the maxillary and mandibular periodontium to induce the disease. AAV-sh-Ctsk was then administrated locally into the periodontal tissues in vivo, followed by analyses to assess progression of the disease. RESULTS AAV-mediated Ctsk silencing drastically protected mice (> 80%) from P. gingivalis-induced bone resorption by osteoclasts. In addition, AAV-sh-Ctsk administration drastically reduced inflammation by impacting the expression of many inflammatory cytokines as well as T-cell and dendritic cell numbers in periodontal lesions. CONCLUSION AAV-mediated Ctsk silencing can simultaneously target both the inflammation and bone resorption associated with periodontitis through its inhibitory effect on immune cells and osteoclast function. Thereby, AAV-sh-Ctsk administration can efficiently protect against periodontal tissue damage and alveolar bone loss, establishing this AAV-mediated local silencing of Ctsk as an important therapeutic strategy for effectively treating periodontal disease.

Abstract
The generation of antiviral drugs from herbs and other natural resources with traditionally long-confirmed effects is an efficient approach. So far, no herb or components from herbs that could inhibit bovine herpesvirus type 1 (BoHV-1) replication have been described. In this study, the antiviral effect of curcumin, a natural phenolic constituent of the spice turmeric, on BoHV-1 replication was evaluated in cell culture. We demonstrated that curcumin impairs BoHV-1 viral particles and affects the virus post-binding entry process. Furthermore, curcumin upregulated the proportion of the plasma membrane adopting a lipid raft conformation in MDBK cells, which supported the previous reports that curcumin can modulate the lipid bilayer. Though the antiviral mechanism of curcumin on BoHV-1 needs further study, we identified for the first time a component from herb that could inhibit BoHV-1 replication, in vitro.

Abstract
INTRODUCTION Rare reports can be found about sex- and age-specific body composition survey among Chinese population. The aim of this study is to explore the change of sex-specific body compositions with aging among Chinese adolescents, adults and elders. METHODS In a large-scale population survey about physiological constants and health conditions, 75,714 subjects who aged from 8 to 80 completed body composition array. Body mass index (BMI), percentage body fat (PBF), water percentage of body weight (WPBW), water percentage of lean body mass (WPLBM), fat-free mass index (FFMI) and basic metabolic rate were examined with Biodynamics BI-310 body composition analyzer. General obesity is defined as BMI equal to or greater than 28 kg/m2. RESULTS The prevalence rates of general obesity were 9.4% for males and 7.7% for females respectively. With aging, PBF and FMI showed a U-shape curvilinear trend and WPBW showed a parabolic trend for males. At same age group: 18-19 age groups, PBF and FMI declined to the valley and WPBW rose to the peak. For females, PBF, WPBW and FMI changed in a linear trend. The values of WPLBM and FFMI showed same curvilinear trend for two genders. WPLBM changed in a U-shape trend and touched the valley in twenties for males and in 18-19 age groups for females. The value of FFMI was larger for older age groups in the younger generation but smaller in the older generation. A parabolic trend peaking was seen in the thirties for males and in the forties for females. Regression models with age as independent variable showed that the larger rate of increase of PBF and smaller rates of increase for WPBM and WPLBM with aging for males. CONCLUSION This study presents detailed data about sex-specific body composition conditions. Different change trend with aging was found about body composition conditions.
