Abstract
Peroxiredoxins (Prxs) play important roles in protecting organisms against damage caused by reactive oxygen species (ROS). In this study, we cloned a cDNA of Bombyx mori peroxiredoxin 5 (BmPrx5), which contained a 565-bp open reading frame for a 188-residue protein. Sequence analysis indicated that BmPrx5 belongs to the atypical 2-Cys peroxiredoxin family. Recombinant BmPrx5 purified from Escherichia coli showed antioxidant activity that removes H2 O2 and protects DNA from oxidative damage. Quantitative real-time PCR showed that the level of BmPrx5 mRNA in haemocytes increased early and decreased by 24 h after injection of H2 O2 whereas, in the fat body, the transcript level decreased at 6 h and increased at 12 h. Pseudomonas aeruginosa and Staphylococcus aureus infection resulted in higher levels of H2 O2 in the haemolymph and of BmPrx5 mRNA in haemocytes at 8 h postinfection. These data suggest that BmPrx5 acts as an antioxidant enzyme to protect the silkworm from oxidative damage induced by bacterial infection. Further study is needed to elucidate the exact role of BmPrx5 in the silkworm immune system.

Abstract
OBJECTIVE The aim of the present investigation was to describe the distribution, structure and allocation of oral health services personnel, evaluate oral health service capacity and predict the needs for oral health services in northern China over the coming 10 years. METHODS The questionnaires were sent to all the dental medical institutions included in this study directly from the Sanitation Bureau and the Health Supervision Station. All the institutions and dental personnel were asked to fill out the questionnaires, and then, the questionnaires were collected through postal service and email. RESULTS In Liaoning Province, which is in northern China, there are a total of 5617 dentists in total, 87.8% of whom are located in urban areas. Dentists in rural areas were found to be less educated and specialized. The ratio of dentists to nurses to technicians was about 6:2:1, and the ratio of dentists to total population was 1:7682. It was predicted that, in 2020, the number of dentists could reach 13 207. This would meet the area's needs for oral health services. CONCLUSION Currently, in northern China, the oral health infrastructure suffers from an insufficient number of dental professionals, disproportionate distribution and inappropriate structure. To improve social equity, it is necessary to adjust the distribution of dental personnel capable of performing for oral health services.

Abstract
Oncolytic adenoviruses, such as Delta-24-RGD, are replication-competent
viruses that are genetically engineered to induce selective cancer cell lysis.
In cancer cells, Delta-24-RGD induces massive autophagy, which is required for
efficient cell lysis and adenoviral spread. Understanding the cellular
mechanisms underlying the regulation of autophagy in cells treated with
oncolytic adenoviruses may provide new avenues to improve the therapeutic
effect. In this work, we showed that cancer cells infected with Delta-24-RGD
undergo autophagy despite the concurrent activation of the AKT/mTOR pathway.
Moreover, adenovirus replication induced sustained activation of JNK proteins
in vitro. ERK1/1 phosphorylation remained unchanged during
adenoviral infection, suggesting specificity of JNK activation. Using genetic
ablation and pharmacological inactivation of JNK, we unequivocally demonstrated
that cells infected with Delta-24-RGD required JNK activation. Thus, genetic
co-ablation of JNK1 and JNK2 genes or
inhibition of JNK kinase function rendered Delta-24-RGD–treated cells
resistant to autophagy. Accordingly, JNK activation induced phosphorylation of
Bcl-2 and prevented the formation of Bcl-2/Beclin 1 autophagy suppressor
complexes. Using an orthotopic model of human glioma xenograft, we showed that
treatment with Delta-24-RGD induced phosphorylation and nuclear translocation of
JNK, as well as phosphorylation of Bcl-2. Collectively, our data identified JNK
proteins as an essential mechanistic link between Delta-24-RGD infection and
autophagy in cancer cells. Activation of JNK without inactivation of the
AKT/mTOR pathway constitutes a distinct molecular signature of autophagy
regulation that differentiates Delta-24-RGD adenovirus from the mechanism used
by other oncolytic viruses to induce autophagy and provides a new rationale for
the combination of oncolytic viruses and chemotherapy.

Abstract
Aseptic loosening associated with wear particle-induced inflammation is a major cause of joint implant failure. Recent studies have demonstrated the therapeutic effects of p38 mitogen-activated protein kinase (MAPK)-based therapies on chronic inflammatory diseases. The purpose of this study was to investigate whether SB203580, a p38 MAPK inhibitor, inhibits wear debris-induced inflammatory osteolysis in mice through downregulation of receptor activator of nuclear factor kβ (RANK)/RANK ligand (RANKL). We used a murine osteolysis model to study the effect of SB203580 on RANKL/RANK signaling and titanium particle-induced osteolysis in vivo. Pouch membranes with intact bone implants were analyzed using histological analysis and transmission electron microscopy, and the levels of RANK and RANKL protein and mRNA were evaluated by immunohistological staining and real-time reverse transcriptase-polymerase chain reaction. SB203580 had less of an effect on RANK and RANKL expression under wear debris-induced conditions. The number of TRAP-positive cells was remarkably reduced in Ti-particle-induced pouch tissues. These effects were confirmed through the transmission electron microscopy results. These results suggest that p38 MAPK-based therapies are beneficial in preventing aseptic loosening associated with total joint replacement by modulating RANK-RANKL signaling.

Abstract
miRNAs (microRNAs) are frequently and aberrantly expressed in many cancers. MiR-873 has been revealed to be downregulated in colorectal cancer and glioblastoma. However, its function remains unclear. Here we report that miR-873 is downregulated in breast tumor compared with normal tissue. Enforced expression of miR-873 decreases the transcriptional activity of ER (estrogen receptor)-α but not ERβ through the modulation of ERα phosphorylation in ER-positive breast cancer cells. We also found that miR-873 inhibits breast cancer cell proliferation and tumor growth in nude mice. Reporter gene assays revealed cyclin-dependent kinase 3 (CDK3) as a direct target of miR-873. CDK3 was shown to be overexpressed in breast cancer and phosphorylate ERα at Ser104/116 and Ser118. Furthermore, we found that Mir-873 inhibits ER activity and cell growth via targeting CDK3. Interestingly, miR-873 was observed to be downregulated in tamoxifen-resistant MCF-7/TamR cells, while CDK3 is overexpressed in these cells. More importantly, re-expression of miR-873 reversed tamoxifen resistance in MCF-7/TamR cells. Our data demonstrate that miR-873 is a novel tumor suppressor in ER-positive breast cancer and a potential therapeutic approach for treatment of tamoxifen-resistant breast cancer.

Abstract
Clinical studies have shown that metabolic syndrome (MetS) is associated with increased risk of developing periodontitis. However, the underlying mechanisms remain largely unknown. Since it is known that lipopolysaccharide (LPS)-activated toll-like receptor 4 signaling pathways play a crucial role in periodontitis, we hypothesized that MetS enhances LPS-induced periodontal inflammation and alveolar bone loss. In this study, we induced MetS in C57BL/6 mice by feeding them high-fat diet (HFD), and we induced periodontitis by periodontal injection of Aggregatibacter actinomycetemcomitans LPS. We found that mice fed a HFD had significantly increased body weight, plasma lipids, insulin, and insulin resistance when compared with mice fed regular chow, indicating that the mice developed MetS. We also found that a HFD markedly increased LPS-induced alveolar bone loss, osteoclastogenesis, and inflammatory infiltration. Analysis of gene expression in periodontal tissue revealed that HFD and LPS injection cooperatively stimulated expression of cytokines that are known to be involved in periodontal tissue inflammation and osteoclastogenesis-such as interleukin 6, monocyte-chemotactic protein 1, receptor activator of nuclear factor kappa-B ligand, and macrophage colony-stimulating factor. To further understand the potential mechanisms involved in MetS-boosted tissue inflammation, our in vitro studies showed that palmitic acid-the most abundant saturated fatty acid (SFA) and the major SFA in the HFD used in our animal study-potently enhanced LPS-induced proinflammatory gene expression in macrophages. In sum, this study demonstrated that MetS was associated with increased periodontal inflammation and alveolar bone loss in an LPS-induced periodontitis animal model. This study also suggests that SFA palmitic acid may play an important role in MetS-associated periodontitis by enhancing LPS-induced expression of inflammatory cytokines in macrophages.

Abstract
pRb and p53 are the two major tumor suppressors. Their inactivation is frequent when cancers develop and their reactivation is rationale of most cancer therapeutics. When pRb and p53 are genetically inactivated, cells irreparably lose the antitumor mechanisms afforded by them. Cancer genome studies document recurrent genetic inactivation of RB1 and TP53, and the inactivation becomes more frequent in more advanced cancers. These findings may explain why more advanced cancers are more likely to resist current therapies. Finding successful treatments for more advanced and multi-therapy resistant cancers will depend on finding antitumor mechanisms that remain effective when pRb and p53 are genetically inactivated. Here, we review studies that have begun to make progress in this direction.

Abstract
Schizophrenia is a complex illness with unknown aetiology and pathogenesis. Currently, a considerable number of patients with schizophrenia do not receive standardised and systematic treatment in China. In the past years, many controlled trials have been conducted in chronic schizophrenia. In contrast, research on first-episode schizophrenia is lacking. This paper describes the background and design of the Chinese First-Episode Schizophrenia Trial project--a multicentre, randomised, open-label clinical trial. A total of 600 first-episode schizophrenia patients were randomly divided into 3 groups and treated with risperidone, aripiprazole, and olanzapine for 1 year. During the study period, only 1 medication change of the 3 antipsychotic medications was allowed.

Abstract
Mycobacterium tuberculosis infection is rarely reported to be associated with acupuncture practices. We performed a retrospective outbreak investigation of a unique outbreak of 33 extrapulmonary M. tuberculosis infections related to acupuncture point injection therapy (AIT) among clients who visited a private traditional Chinese medicine clinical centre in China. The lumps, abscesses and ulcers occurred mostly on the neck, shoulders, waist, knees and hips, localized at acupuncture point meridian sites. These symptoms appeared from January to November 2011, with a peak cluster of infections in September 2011 (nine cases). M. tuberculosis Beijing strain was isolated and confirmed by DNA sequencing. All diagnosed patients were treated empirically with appropriate antibiotic treatment, and their condition improved. Our study indicated that this outbreak was most likely resulted from contaminated AIT. Drafting standard guidelines for AIT is urgently needed, and routine medical supervision should be provided, including obligating health providers to perform routine physical examinations that include testing for infectious diseases.

Abstract
Ambient fine particulate matter (PM2.5) is a leading environmental risk factor for premature mortality. We use aerosol optical depth (AOD) retrieved from two satellite instruments, MISR and SeaWiFS, to produce a unified 15-year global time series (1998-2012) of ground-level PM2.5 concentration at a resolution of 1° x 1°. The GEOS-Chem chemical transport model (CTM) is used to relate each individual AOD retrieval to ground-level PM2.5. Four broad areas showing significant, spatially coherent, annual trends are examined in detail: the Eastern U.S. (-0.39 ± 0.10 μg m(-3) yr(-1)), the Arabian Peninsula (0.81 ± 0.21 μg m(-3) yr(-1)), South Asia (0.93 ± 0.22 μg m(-3) yr(-1)) and East Asia (0.79 ± 0.27 μg m(-3) yr(-1)). Over the period of dense in situ observation (1999-2012), the linear tendency for the Eastern U.S. (-0.37 ± 0.13 μg m(-3) yr(-1)) agrees well with that from in situ measurements (-0.38 ± 0.06 μg m(-3) yr(-1)). A GEOS-Chem simulation reveals that secondary inorganic aerosols largely explain the observed PM2.5 trend over the Eastern U.S., South Asia, and East Asia, while mineral dust largely explains the observed trend over the Arabian Peninsula.

Abstract
Pharmaceutical and personal care products (PPCPs) and endocrine disrupting chemicals (EDCs) enter the soil environment via irrigation with treated wastewater, groundwater recharge, and land application of biosolids. The transformation and fate of PPCP/EDCs in soil affects their potential for plant uptake and groundwater pollution. This study examined four PPCP/EDCs (bisphenol A, diclofenac, naproxen, and 4-nonylphenol) in soil by using (14)C-labeling and analyzing mineralization, extractable residue, bound residue, and formation of transformation products. At the end of 112 d of incubation, the majority of (14)C-naproxen and (14)C-diclofenac was mineralized to (14)CO2, while a majority of (14)C-bisphenol A and (14)Cnonylphenol was converted to bound residue. After 112 d, the estimated half-lives of the parent compounds were only 1.4-5.4 d. However a variety of transformation products were found and several for bisphenol A and diclofenac were identified, suggesting the need to consider degradation intermediates in soils impacted by PPCP/EDCs.

Abstract
A mandrel winding method, which can realize remarkable homogeneous plastic deformation at room temperature for various metallic glasses, is applied to characterize plastic flow units and study their relationship with macroscopic deformations and relaxations. The method can provide information on the activation energy, activation time, size, intrinsic relaxation time, distribution, and density of flow units. We find the plasticity of a metallic glass can be controlled through modulating the features of flow units. The results have benefits for better understanding the structural origins of deformations and relaxations, and for designing metallic glasses with improved performances.

Abstract
Classical swine fever virus (CSFV) Core protein is involved in virus RNA protection, transcription regulation and virus virulence. To discover additional Core protein functions a yeast two-hybrid system was used to identify host proteins that interact with Core. Among the identified host proteins, the osteosarcoma amplified 9 protein (OS9) was further studied. Using alanine scanning mutagenesis, the OS9 binding site in the CSFV Core protein was identified, between Core residues (90)IAIM(93), near a putative cleavage site. Truncated versions of Core were used to show that OS9 binds a polypeptide representing the 12 C-terminal Core residues. Cells transfected with a double-fluorescent labeled Core construct demonstrated that co-localization of OS9 and Core occurred only on unprocessed forms of Core protein. A recombinant CSFV containing Core protein where residues (90)IAIM(93) were substituted by alanines showed no altered virulence in swine, but a significant decreased ability to replicate in cell cultures.

Abstract
The process of autophagy has been described in detail at the molecular level in normal cells, but less is known of its regulation in cancer cells. Aplasia Ras homolog member I (ARHI; DIRAS3) is an imprinted tumor suppressor gene that is downregulated in multiple malignancies including ovarian cancer. Re-expression of ARHI slows proliferation, inhibits motility, induces autophagy and produces tumor dormancy. Our previous studies have implicated autophagy in the survival of dormant ovarian cancer cells and have shown that ARHI is required for autophagy induced by starvation or rapamycin treatment. Re-expression of ARHI in ovarian cancer cells blocks signaling through the PI3K and Ras/MAP pathways, which, in turn, downregulates mTOR and initiates autophagy. Here we show that ARHI is required for autophagy-meditated cancer cell arrest and ARHI inhibits signaling through PI3K/AKT and Ras/MAP by enhancing internalization and degradation of the epidermal growth factor receptor. ARHI-mediated downregulation of PI3K/AKT and Ras/ERK signaling also decreases phosphorylation of FOXo3a, which sequesters this transcription factor in the nucleus. Nuclear retention of FOXo3a induces ATG4 and MAP-LC3-I, required for maturation of autophagosomes, and also increases the expression of Rab7, required for fusion of autophagosomes with lysosomes. Following the knockdown of FOXo3a or Rab7, autophagolysosome formation was observed but was markedly inhibited, resulting in numerous enlarged autophagosomes. ARHI expression correlates with LC3 expression and FOXo3a nuclear localization in surgical specimens of ovarian cancer. Thus, ARHI contributes to the induction of autophagy through multiple mechanisms in ovarian cancer cells.

Abstract
A key challenge for volcanological science and hazard management is that few of the world’s volcanoes are effectively monitored. Satellite imagery covers volcanoes globally throughout their eruptive cycles, independent of ground-based monitoring, providing a multidecadal archive suitable for probabilistic analysis linking deformation with eruption. Here we show that, of the 198 volcanoes systematically observed for the past 18 years, 54 deformed, of which 25 also erupted. For assessing eruption potential, this high proportion of deforming volcanoes that also erupted (46%), together with the proportion of non-deforming volcanoes that did not erupt (94%), jointly represent indicators with ‘strong’ evidential worth. Using a larger catalogue of 540 volcanoes observed for 3 years, we demonstrate how this eruption–deformation relationship is influenced by tectonic, petrological and volcanic factors. Satellite technology is rapidly evolving and routine monitoring of the deformation status of all volcanoes from space is anticipated, meaning probabilistic approaches will increasingly inform hazard decisions and strategic development. Deformation is often used in volcano monitoring, but the associated hazard is hard to interpret. Biggs et al. analyse 20 years of global satellite data and show a strong statistical link between deformation and eruption, although deformation alone is not necessarily a precursor of imminent eruption.

Abstract
WHAT IS KNOWN AND OBJECTIVE AZD7325 is a selective gamma-amino-butyric acid (GABAA )α2, 3 receptor modulator. The aims of this analysis were to develop population pharmacokinetic (PPK) models of AZD7325 and midazolam and to assess the induction effect of AZD7325 on CYP3A4 with midazolam as a substrate. METHODS Drug-drug interaction data of AZD7325 and midazolam from 24 healthy subjects were available for model development. PPK models were developed in a sequential manner using NONMEM. Both AZD7325 and midazolam pharmacokinetics were described by two-compartment models, and a transit compartment absorption model and a first-order absorption model were applied for the absorption of AZD7325 and midazolam, respectively. The induction of CYP3A by AZD7325 was described by a transit enzyme model, where the elimination of midazolam was proportionally linked to the enzyme amount. Simulations were performed to predict dosing regimens to account for the induction of CYP3A4. RESULTS AND DISCUSSION The population estimates for AZD7325 clearance, intercompartmental clearance, central and peripheral volume were 36, 29·2 L/h, 169 and 392 L, respectively, with interindividual variability (IIV) of 35% and 24% for clearance and central volume. Midazolam clearance, intercompartmental clearance, central and peripheral volume were estimated to be 62·7, 34·7 L/h, 133 and 146 L, respectively, with 43% IIV for clearance. The estimated mean transit time for induction of the CYP3A4 enzyme was 197 h, with 57% IIV. WHAT IS NEW AND CONCLUSION The PPK models developed adequately described the clinical observation of AZD7325-mediated CYP3A4 enzyme induction with midazolam as a probe. The model could provide basis for the rational dosing of AZD7325 in clinical practice.

Abstract
Neuromyelitis optica (NMO) and multiple sclerosis (MS) are two of the autoimmune inflammatory demyelinating diseases in the central nervous system. Complement is thought to have an important role in pathogenesis of these diseases, especially in NMO. However, the change of terminal complement complex (TCC, C5b-9) in patients with NMO is still unclear. Cerebrospinal fluid (CSF) C3a, C5a, sC5b-9 were measured by enzyme-linked immunosorbent assay in patients with NMO (n = 26), MS (n = 25) and other neurological disease (OND, n = 19). CSF levels of C5a in patients with NMO were higher than patients with OND (P = 0.006). Increased CSF sC5b-9 were found in the patients with NMO compared with patients with MS (P = 0.029) and OND (P = 0.0001). CSF sC5b-9 in patients with MS were also higher than patients with OND (P = 0.030). Patients with NMO revealed a trend to an increased disease disability with increased CSF sC5b-9 during relapse but not in MS (NMO: P = 0.006, MS: P = 0.097). CSF levels of sC5b-9 are increased in patients with NMO and reflect the activation of complement in NMO.

Abstract
Studies in recent years have shown a positive relationship between metabolic syndrome (MS) and periodontal disease (PD). Given that patients with MS take statins to reduce cholesterol, and statins also have anti-inflammatory effects, it is important to determine if statin intake hinders the progression of MS-associated PD. In this study, PD was induced in Zucker fat rats (ZFRs), an animal model for MS, and in control lean rats by periodontal injection of Aggregatibacter actinomycetemcomitans lipopolysaccharide (LPS), while simvastatin was given to some of the rats via gavage. After 4 wk of treatment, alveolar bone loss was determined by micro-computed tomography. To explore the underlying mechanisms, we determined the effect of simvastatin on tissue inflammation and the expression of molecules involved in osteoclastogenesis. Results showed that while bone loss was increased by LPS in both ZFRs and the control lean rats, it was significantly more in the former than the latter. Simvastatin effectively alleviated bone loss in both ZFRs and the control rats. Results also showed that LPS stimulated leukocyte tissue infiltration and expression of molecules for osteoclastogenesis, but simvastatin significantly modulated the stimulation. This study demonstrated that simvastatin inhibited LPS-induced alveolar bone loss and periodontal tissue inflammation in rats with MS.

Abstract
Functional genomics studies have led to the discovery of a large amount of non-coding RNAs from the human genome; among them are long non-coding RNAs (lncRNAs). Emerging evidence indicates that lncRNAs could have a critical role in the regulation of cellular processes such as cell growth and apoptosis as well as cancer progression and metastasis. As master gene regulators, lncRNAs are capable of forming lncRNA–protein (ribonucleoprotein) complexes to regulate a large number of genes. For example, lincRNA-RoR suppresses p53 in response to DNA damage through interaction with heterogeneous nuclear ribonucleoprotein I (hnRNP I). The present study demonstrates that hnRNP I can also form a functional ribonucleoprotein complex with lncRNA urothelial carcinoma-associated 1 (UCA1) and increase the UCA1 stability. Of interest, the phosphorylated form of hnRNP I, predominantly in the cytoplasm, is responsible for the interaction with UCA1. Moreover, although hnRNP I enhances the translation of p27 (Kip1) through interaction with the 5′-untranslated region (5′-UTR) of p27 mRNAs, the interaction of UCA1 with hnRNP I suppresses the p27 protein level by competitive inhibition. In support of this finding, UCA1 has an oncogenic role in breast cancer both in vitro and in vivo. Finally, we show a negative correlation between p27 and UCA in the breast tumor cancer tissue microarray. Together, our results suggest an important role of UCA1 in breast cancer.

Abstract
OBJECTIVE The purpose of this work is to investigate the feasibility of acoustic radiation force impulse (ARFI) technology in the normal mammary parenchyma and in breast lesions. MATERIALS AND METHODS The virtual touch tissue quantification (VTQ) value was measured on a total of 150 cases in the normal mammary parenchyma and a total of 69 cases in breast lesions (19 cases of nodules, 28 cases of fibroadenoma, and 22 cases of cancer). Then the statistic analysis was carried out on the VTQ value combined with mammographic density, ages, menstrual stages, and pathological result. RESULTS The VTQ value of mammary parenchyma rose with the increase of the mammographic density, and the value of VTQ had statistical differences in the comparison of group C with group B and in the comparison of group D with group C. The comparison of the VTQ value of the mammary parenchyma in patients with breast cancer and the nodule had statistical difference. The comparison of the VTQ value of the mammary parenchyma in patients with breast cancer, and the fibroadenoma had statistical difference. The value ofVTQ in masses gradually increased in the groups of nodule, fibroadenoma, and breast cancer. There was significant difference in the comparison of VTQ value of the nodule group and the fibroadenoma group with breast cancer group respectively. CONCLUSION ARFI-VTQ technology has some reference value in assessing mammographic density. ARFI-VTQ can be used as the quantitative indicater for differentially diagnosing the breast lesions.

Abstract
OBJECTIVES Bipolar disorder is often misdiagnosed as major depressive disorder. Such misdiagnosis partly depends on the type of treatment setting. This study compared general hospital psychiatric units with psychiatric hospitals in China with respect to basic demographic and clinical characteristics of patients with unrecognised bipolar disorder who are treated for major depressive disorder. METHODS Patients treated for major depressive disorder were consecutively examined in 13 health centres (6 general hospital psychiatric units and 7 psychiatric hospitals) in China. Their socio-demographic and clinical features were recorded using a standardised protocol and data collection procedure. The DSM-IV diagnoses were established using the Mini-International Neuropsychiatric Interview. RESULTS Of the 1487 patients included in the study, 309 (20.8%) were diagnosed with bipolar disorder. There was no significant difference between general hospital psychiatric units and psychiatric hospitals in the ratio of all types of unrecognised bipolar disorders (χ2 = 0.008, degrees of freedom = 1, p = 0.9) and bipolar II disorders (χ2 = 3.1, degrees of freedom = 1, p = 0.08). The proportions of unrecognised bipolar I disorders (χ2 = 4.1, degrees of freedom = 1, p = 0.04) differed significantly between the 2 types of study site. Multivariate analyses showed that patients with bipolar I disorders with more seasonal depressive episodes were more likely to receive treatment in general hospital psychiatric units (odds ratio = 3.3, 95% confidence interval = 1.1-9.8). CONCLUSION Patients with bipolar I disorders receiving treatment in general hospital psychiatric units had different clinical characteristics compared to their counterparts treated in psychiatric hospitals in China.

Abstract
BACKGROUND AND OBJECTIVE Statins are inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase and have anti-inflammatory effects independent of cholesterol lowering. Recent clinical studies have indicated that statin intake has a beneficial effect on periodontal disease. However, the underlying mechanisms have not been well understood. In the current study, we employed a rat model with lipopolysaccharide (LPS)-induced periodontal disease and determined the effect of simvastatin, a commonly prescribed statin, on osteoclastogenesis, gingival inflammation and alveolar bone loss. MATERIAL AND METHODS Sprague-Dawley rats were injected with Aggregatibacter actinomycetemcomitans LPS in periodontal tissue three times per week for 8 wk and part of the rats with LPS injection were also given simvastatin via gavage. After the treatments, the rat maxillae were scanned by microcomputed tomography and the images were analyzed to determine alveolar bone loss. To explore the underlying mechanisms, the effect of simvastatin on osteoclastogenesis and gingival expression of proinflammatory cytokines were also determined by tartrate-resistant acid phosphatase staining and real-time polymerase chain reaction assays, respectively. RESULTS Results showed that LPS treatment markedly increased bone loss, but administration of simvastatin significantly alleviated the bone loss. Results also showed that LPS treatment stimulated osteoclastogenesis and the expression of inflammatory cytokines, but simvastatin significantly modulates the stimulatory effect of LPS on osteoclastogenesis and cytokine expression. CONCLUSION This study demonstrated that simvastatin treatment inhibits LPS-induced osteoclastogenesis and gingival inflammation and reduces alveolar bone loss, indicating that the intake of simvastatin may hinder the progression of periodontal disease.

Abstract
UNLABELLED Methyl parathion hydrolase (MPH) can degrade a wide range of organophosphorus compounds, but its efficiency in hydrolysing chlorpyrifos, one of the most popular pesticides applied for crop protection, is much lower than that in hydrolysing the preferred substrate methyl parathion. In this study, random mutagenesis was adopted to improve MPH to enhance its efficiency in hydrolysing the poorly hydrolysed substrate chlorpyrifos. Rapid screening of the improved MPH variants was carried out using Bacillus subtilis WB800 secretory expression system to investigate the distribution of improved MPH variants based on the size of clear haloes as a result of chlorpyrifos hydrolysis. Four improved MPH variants were isolated, and one variant K3, in particular, showed a 5-fold increase in kcat value for chlorpyrifos hydrolysis. Furthermore, most of the MPH variants obtained in this study possessed enhanced thermostability and pH stability. The approaches adopted in this study could be extended to create other MPH variants with increased activity for hydrolysing other poorly hydrolysed substrates. SIGNIFICANCE AND IMPACT OF THE STUDY Chlorpyrifos is one of the toxic organophosphorus compounds (OP compounds) widely used for insecticides control. Water, soil and foodstuff have been contaminated seriously by chlorpyrifos in some areas. It is urgent to find effective methods to remove its contamination. This work contributes to improve methyl parathion hydrolase (MPH) to enhance its efficiency in hydrolysing the poorly hydrolysed substrate chlorpyrifos. Our study brings new insights for enzymatic strategy for the decontamination of toxic OP compounds.

Abstract
Intrinsic connectivity networks (ICNs) are composed of spatial components and time courses. The spatial components of ICNs were discovered with moderate-to-high reliability. So far as we know, few studies focused on the reliability of the temporal patterns for ICNs based their individual time courses. The goals of this study were twofold: to investigate the test-retest reliability of temporal patterns for ICNs, and to analyze these informative univariate metrics. Additionally, a correlation analysis was performed to enhance interpretability. Our study included three datasets: (a) short- and long-term scans, (b) multi-band echo-planar imaging (mEPI), and (c) eyes open or closed. Using dual regression, we obtained the time courses of ICNs for each subject. To produce temporal patterns for ICNs, we applied two categories of univariate metrics: network-wise complexity and network-wise low-frequency oscillation. Furthermore, we validated the test-retest reliability for each metric. The network-wise temporal patterns for most ICNs (especially for default mode network, DMN) exhibited moderate-to-high reliability and reproducibility under different scan conditions. Network-wise complexity for DMN exhibited fair reliability (ICC<0.5) based on eyes-closed sessions. Specially, our results supported that mEPI could be a useful method with high reliability and reproducibility. In addition, these temporal patterns were with physiological meanings, and certain temporal patterns were correlated to the node strength of the corresponding ICN. Overall, network-wise temporal patterns of ICNs were reliable and informative and could be complementary to spatial patterns of ICNs for further study.

Abstract
Neurosurgical interventions date back to ancient civilization, 5100 BC through a practice known as trephination. Due to past abuse and ethical considerations, neurosurgical interventions in psychiatry remain a controversial issue. This article aims to review the different surgical techniques and their current application in the treatment of psychiatric disorders. The U.S Food and Drug Administration (FDA) gave its approval for vagal nerve stimulation (VNS) for the management of treatment-resistant depression in 2005 and deep brain stimulation (DBS) for refractory obsessive-compulsive disorders (OCD) in 2009. These invasive but non destructive techniques represent the future of neurosurgery for mental disorder.

Abstract
To improve the expression levels of transgenes in malignant hematopoietic cells, we developed a novel adenoviral-alphavirus hybrid vector Ad5/F11p-SFV-GFP that contains a Semliki Forest Virus (SFV) replicon and chimeric fibers of Ad5 and Ad11p. Ad5/F11p-SFV-GFP infected >95% of K562, U937 or Jurkat cells and 23.65% of HL-60 cells, and led to moderate Enhanced Green Fluorescent Protein (EGFP) transgene expression intensity. The infection efficiency of Ad5/F11p-SFV-GFP in primary human leukemia cells ranged from 9.34-89.63% (median, 28.58%) at a multiplicity of infection (MOI) of 100, compared with only 3.37-44.54% (median, 10.42%) in cells infected by Ad5/F11p-GFP. Importantly, Ad5/F11p-SFV-GFP led to a significantly higher transgene expression level in primary leukemia cells, as indicated by the relative fluorescence intensity, compared to cells infected with Ad5/F11p-GFP. The increased expression of EGFP in Ad5/F11p-SFV-GFP-infected cells was associated with the accumulation of abundant subgenomic mRNA. Additionally, infection of K562, U937 or Jurkat cells by Ad5/F11p-SFV-GFP was significantly inhibited by blocking CD46 receptor; however, other factors may affect the gene-transfer efficiency of Ad5/F11p-SFV-GFP in primary leukemia cells. In conclusion, we successfully developed a novel adenoviral-alphavirus hybrid vector with RNA replicon features, which represents a promising vector for gene modifications during the production of cell-based vaccines for leukemia patients.
