SummaryThe Amami Thrush, Zoothera dauma major, is an endemic subspecies of the Eurasian Scaly Thrush that is distributed only on Amami-Oshima Island in south-western Japan. This bird was formerly considered to be a distinct species (Z. major) and was listed on the IUCN Red List as ‘Critically Endangered’ based on the small population size estimated in the early 2000s. To re-evaluate the conservation status of this bird, we estimated the number of singing males from song-count surveys conducted by an NPO with public participation from 2007 to 2013. An estimation that applied a distance sampling method revealed the number of singing males to be 945–1,858 up to 2012. A sudden increase in song counts was recorded in 2013, and the estimate increased to 2,512 in 2013. Based on the assumption that the sex ratio does not deviate from 1:1, simply doubling the number was considered to produce the estimated population size (number of males and females that are capable of breeding). The present study also confirmed that the Amami Thrush was more abundant in older forest with less open habitat, suggesting that forest maturity is an important factor for thrush abundance. The relative density of the invasive small Indian mongoose Herpestes auropunctatus probably affected thrush abundance before the early 2010s prior to mongoose eradication efforts. Our results suggest that thrush recovery was likely associated with forest regeneration and mongoose eradication. However, it is important to continue population monitoring approaches including public participation to promote further conservation of the Amami Thrush.

AbstractCombined oral contraceptives (COCs), colloquially referred to as “the pill,” have been regarded as a medical breakthrough, as they have improved the lives of countless women, from simplifying family planning to the treatment of acne, endometriosis, polycystic ovarian syndrome, and dysmenorrhea. Unfortunately, COC usage has been associated with an increased occurrence of venous thrombosis and therefore a systemic hypercoagulable state in susceptible females. Here we discuss the health risks of COC usage and use viscoelastic and morphological techniques to investigate the effect of different COC constituents on clot formation, particularly fibrin network packaging and whole blood viscoelasticity. Viscoelastic properties of whole blood showed gender-specific changes while morphological alterations were person-specific, regardless of gender. Using scanning electron microscopy and thromboelastography provides great insight regarding fibrin packaging and the development of a hypercoagulable state in high-risk individuals. We proposed a three-step approach where (1) an individual’s coagulation profile baseline is determined, after which (2) the “ideal” combination of constituents is prescribed, and (3) the coagulation profile of the individual is monitored to assess possible risk of thrombosis. Only in following such an individualized patient-oriented approach will we be able to avoid the many health issues due to COC usage in susceptible females.
Elusive East Asia:MethodologicalSuggestions for the Study of East Asian Security
Authors: EUN YONG-SOO 
Published: August 2016

AbstractThis article attempts to fill a gap in International Relations (IR) literature on East Asian security. ‘East Asia’ appears to be mostly an indeterminate conceptual construct, allowing scholars to look selectively at those aspects and areas that could justify their security thesis,albeitsecurity dynamics in the region are all too difficult to comprehend and predict. This problem has been frequently pointed out in IR literature, but itsmethodologicalimplications and suggestions have neither been appropriately illuminated nor been systematically offered, and the main solution commonly found in the literature was the tautological one of ‘better defining’ the region. As an alternative, this article suggests that one needs to tighten geographical focus and differentiate the subjects of analysis. When it comes to the study of East Asian security, one needs to aim to develop specific and differentiated generalizationsas opposed togeneralizations of a broad character. To showcase the fact that research outcomes can be more determinate when the target of analysis is more focused and specified, this article takes Northeast Asian security as an example and challenges the so-called ‘peaceful East Asia’ thesis, one of the mainstream perspectives on East Asian security. This article ultimately argues that while apprehending East Asian security dynamicsthroughdelimiting the scope of analysis and circumscribing the subjects of investigation is often deemed to be a modest enterprise―in particular, in terms of generalizability―the merits are substantial: research outcomes will be able not only to give us a truer mapping of the real world, but also bring us closer to building knowledge which satisfies the scientific criterion of ‘falsifiability.’
Toward Modelling a Global Social Contract: Jean-Jacques Rousseau and John Locke
Authors: INOGUCHI TAKASHI , LE LIEN THI QUYNH 
Published: August 2016

AbstractThe paper attempts to construct a global model of a social contract using well-known metaphors of two great philosophers: Jean-Jacques Rousseau and John Locke. By modelling a global social contract, I mean the formulation of a social contract using two sets of data: one is global citizens' preferences about values and norms while the other is sovereign states' participation in multilateral treaties. Both Rousseau and Locke formulate their versions of social contract theories in the national context of eighteenth-century Europe. This paper tries my hands on extending their theories to the global context. This paper attempts to link empirically the relationship between global citizens' preferences as gauged by the World Values Survey and sovereign states' participation in 120 multilateral treaties deposited to the United Nations. To see the link between citizens and treaties (quasi-legislative outcomes, sort of), dimensional similarities of the cosmos of citizens' preference and the cosmos of sovereign states' willingness to join multilateral treaties are examined. Once done, all the sovereign states are located in each of the two cosmoses, citizens and states, and the correlation coefficients between them are measured. Based on these empirical results, the nature of the global quasi-legislative process is clarified. Conclusions and implications are drawn.

ABSTRACTObjective:Antiretroviral therapy (ART) affords longevity to patients infected with the human immune deficiency virus (HIV). Since little is known about the health-related quality of life (HRQoL) of persons who have been on ART for at least five years, the present study investigated the HRQoL of these patients in Botswana.Method:Medical records, structured interviews, and the World Health Organization Quality of Life–BREF (WHOQoL–HIV–BREF) instrument were employed to obtain information from 456 respondents.Results:Univariate and multivariate regression analyses showed that respondents' highest scores were in the “physical” domain (mean = 15.8, SD = 3.5), while the lowest scores were in the “environment” domain (mean = 12.9, SD = 2.5). Thus, the physical domain had the greatest impact on patients' overall HRQoL. Self-education about HIV-related issues was significantly correlated with all domains of HRQoL scores: physical (ρ = –2.32, CI95% = –3.02, –1.61); psychological (ρ = –2.26, CI95% = –2.87, –1.65); independence (ρ = –1.81, CI95% = –2.54, –1.06); social relationships (ρ = –1.40, CI95% = –2.13, –0.67); environment (ρ = –1.58, CI95% = –2.13, –1.04); and spirituality (ρ = –1.70, CI95% = –82.27, –1.13).Significance of results:HRQoL assessments can identify and address patients' needs, and it is important that guidelines be developed that will yield improved care to ART patients in Botswana.

AbstractWhen visual input has conflicting interpretations, conscious perception can alternate spontaneously between these possible interpretations. This is called bistable perception. Previous neuroimaging studies have indicated the involvement of two right parietal areas in resolving perceptual ambiguity (ant-SPLr and post-SPLr). Transcranial magnetic stimulation (TMS) studies that selectively interfered with the normal function of these regions suggest that they play opposing roles in this type of perceptual switch. In the present study, we investigated this fractionation of parietal function by use of combined TMS with electroencephalography (EEG). Specifically, while participants viewed either a bistable stimulus, a replay stimulus, or resting-state fixation, we applied single pulse TMS to either location independently while simultaneously recording EEG. Combined with participant’s individual structural magnetic resonance imaging (MRI) scans, this dataset allows for complex analyses of the effect of TMS on neural time series data, which may further elucidate the causal role of the parietal cortex in ambiguous perception.
Full data acquisition in Kelvin Probe Force Microscopy: Mapping dynamic electric phenomena in real space

Published: August 2016

AbstractKelvin probe force microscopy (KPFM) has provided deep insights into the local electronic, ionic and electrochemical functionalities in a broad range of materials and devices. In classical KPFM, which utilizes heterodyne detection and closed loop bias feedback, the cantilever response is down-sampled to a single measurement of the contact potential difference (CPD) per pixel. This level of detail, however, is insufficient for materials and devices involving bias and time dependent electrochemical events; or at solid-liquid interfaces, where non-linear or lossy dielectrics are present. Here, we demonstrate direct recovery of the bias dependence of the electrostatic force at high temporal resolution using General acquisition Mode (G-Mode) KPFM. G-Mode KPFM utilizes high speed detection, compression and storage of the raw cantilever deflection signal in its entirety at high sampling rates. We show how G-Mode KPFM can be used to capture nanoscale CPD and capacitance information with a temporal resolution much faster than the cantilever bandwidth, determined by the modulation frequency of the AC voltage. In this way, G-Mode KPFM offers a new paradigm to study dynamic electric phenomena in electroactive interfaces as well as a promising route to extend KPFM to the solid-liquid interface.

Published: August 2016

AbstractNanostructured Au nano-platelets have been synthesized from an Au(III) complex by growth process triggered by nanodiamond (ND). An electroless synthetic route has been used to obtain 2D Au/ND architectures, where individual nanodiamond particles are intimately embedded into face-centered cubic Au platelets. The combined use of high resolution transmission electron microscopy (HR-TEM) and selected area electron diffraction (SAED), was able to reveal the unusual organization of these hybrid nanoparticles, ascertaining the existence of preferential crystallographic orientations for both nanocrystalline species and highlighting their mutual locations. Detailed information on the sample microstructure have been gathered by fast Fourier transform (FFT) and inverse fast Fourier transform (IFFT) of HR-TEM images, allowing us to figure out the role of Au defects, able to anchor ND crystallites and to provide specific sites for heteroepitaxial Au growth. Aggregates constituted by coupled ND and Au, represent interesting systems conjugating the best optoelectronics and plasmonics properties of the two different materials. In order to promote realistically the applications of such outstanding Au/ND materials, the cooperative mechanisms at the basis of material synthesis and their influence on the details of the hybrid nanostructures have to be deeply understood.

Published: August 2016

AbstractAcute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are characterized by an excessive inflammatory response within the lungs and severely impaired gas exchange resulting from alveolar-capillary barrier disruption and pulmonary edema. The costimulatory protein B7H3 functions as both a costimulator and coinhibitor to regulate the adaptive and innate immune response, thus participating in the development of microbial sepsis and pneumococcal meningitis. However, it is unclear whether B7H3 exerts a beneficial or detrimental role during ALI. In the present study we examined the impact of B7H3 on pulmonary inflammatory response, polymorphonuclear neutrophil (PMN) influx and lung tissue damage in a murine model of lipopolysaccharide (LPS)-induced direct ALI. Treatment with B7H3 protected mice against LPS-induced ALI, with significantly attenuated pulmonary PMN infiltration, decreased lung myeloperoxidase (MPO) activity, reduced bronchoalveolar lavage fluid (BALF) protein content and ameliorated lung pathological changes. In addition, B7H3 significantly diminished LPS-stimulated PMN chemoattractant CXCL2 production by inhibiting NF-κB p65 phosphorylation and substantially attenuated LPS-induced PMN chemotaxis and transendothelial migration by down-regulating CXCR2 and Mac-1 expression. These results demonstrate that B7H3 substantially ameliorates LPS-induced ALI and this protection afforded by B7H3 is predominantly associated with its inhibitory effect on pulmonary PMN migration and infiltration.

AbstractThere is a need, in NAFLD management, to develop non-invasive methods to detect steatohepatitis (NASH) and to predict advanced fibrosis stages. We evaluated a tool based on optical analysis of liver magnetic resonance images (MRI) as biomarkers for NASH and fibrosis detection by investigating patients with biopsy-proven NAFLD who underwent magnetic resonance (MR) protocols using 1.5T General Electric (GE) or Philips devices. Two imaging biomarkers (NASHMRI and FibroMRI) were developed, standardised and validated using area under the receiver operating characteristic curve (AUROC) analysis. The results indicated NASHMRI diagnostic accuracy for steatohepatitis detection was 0.83 (95% CI: 0.73–0.93) and FibroMRI diagnostic accuracy for significant fibrosis determination was 0.85 (95% CI: 0.77–0.94). These findings were independent of the MR system used. We conclude that optical analysis of MRI has high potential to define non-invasive imaging biomarkers for the detection of steatohepatitis (NASHMRI) and the prediction of significant fibrosis (FibroMRI) in NAFLD patients.
Insight into the cellular fate and toxicity of aluminium adjuvants used in clinically approved human vaccinations
Authors: Mold Matthew , Shardlow Emma , Exley Christopher 
Published: August 2016

AbstractAluminium adjuvants remain the most widely used and effective adjuvants in vaccination and immunotherapy. Herein, the particle size distribution (PSD) of aluminium oxyhydroxide and aluminium hydroxyphosphate adjuvants was elucidated in attempt to correlate these properties with the biological responses observed post vaccination. Heightened solubility and potentially the generation of Al3+ in the lysosomal environment were positively correlated with an increase in cell mortality in vitro, potentially generating a greater inflammatory response at the site of simulated injection. The cellular uptake of aluminium based adjuvants (ABAs) used in clinically approved vaccinations are compared to a commonly used experimental ABA, in an in vitro THP-1 cell model. Using lumogallion as a direct-fluorescent molecular probe for aluminium, complemented with transmission electron microscopy provides further insight into the morphology of internalised particulates, driven by the physicochemical variations of the ABAs investigated. We demonstrate that not all aluminium adjuvants are equal neither in terms of their physical properties nor their biological reactivity and potential toxicities both at the injection site and beyond. High loading of aluminium oxyhydroxide in the cytoplasm of THP-1 cells without immediate cytotoxicity might predispose this form of aluminium adjuvant to its subsequent transport throughout the body including access to the brain.

Hippo pathway is a highly conservative signalling pathway related to the development of organisms, which has been demonstrated to be strongly linked to the tumorigenesis and tumour progression. As the major downstream effector of Hippo pathway, yes-associated protein (YAP), is a transcriptional activator of target genes that are involved in cell proliferation and survival. As an oncogene, YAP can promote cell growth and inhibit cell apoptosis. Another major downstream effector of Hippo pathway, transcriptional co-activators with PDZ-binding motif (TAZ), is nearly 60% homologous with YAP. In the present study, we assume that TAZ probably has the similar function to YAP. To test this issue, we established an inducible and a stable expression system of TAZ in T-Rex-293 and HEK293 cells respectively. The results of cell growth curves, colony formation assay and tumour xenograft growth showed that overexpression of TAZ could promote cell growth in vitro and in vivo. Meanwhile, we found that up-regulated expression of TAZ could partially restore Celastrol-induced cell apoptosis. Induced overexpression of TAZ could up-regulate its target genes including ankyrin repeat domain-containing protein (ANKRD), cysteine-rich 61 (CYR61) and connective tissue growth factor (CTGF), increase the expression of B-cell lymphoma-2 (Bcl-2), decrease the expression of Bcl-2 associated X protein (Bax) and activate the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway, which may be the mechanism underlying anti-apoptosis of TAZ. All these findings indicated that TAZ acts as an oncogene that could be a key regulator of cell proliferation and apoptosis.
Membrane proteins: is the future disc shaped?
Authors: Lee Sarah C. , Pollock Naomi L. 
Published: August 2016

The use of styrene maleic acid lipid particles (SMALPs) for the purification of membrane proteins (MPs) is a rapidly developing technology. The amphiphilic copolymer of styrene and maleic acid (SMA) disrupts biological membranes and can extract membrane proteins in nanodiscs of approximately 10 nm diameter. These discs contain SMA, protein and membrane lipids. There is evidence that MPs in SMALPs retain their native structures and functions, in some cases with enhanced thermal stability. In addition, the method is compatible with biological buffers and a wide variety of biophysical and structural analysis techniques. The use of SMALPs to solubilize and stabilize MPs offers a new approach in our attempts to understand, and influence, the structure and function of MPs and biological membranes. In this review, we critically assess progress with this method, address some of the associated technical challenges, and discuss opportunities for exploiting SMA and SMALPs to expand our understanding of MP biology.
Emerging roles of the bone morphogenetic protein pathway in cancer: potential therapeutic target for kinase inhibition
Authors: Jiramongkolchai Pawina , Owens Philip , Hong Charles C. 
Published: August 2016

Bone morphogenetic proteins (BMPs) belong to the transforming growth factor-β (TGF-β) family signalling pathway. Similar to TGF-β, the complex roles of BMPs in development and disease are demonstrated by their dichotomous roles in various cancers and cancer stages. Although early studies implicated BMP signalling in tumour suppressive phenotypes, the results of more recent experiments recognize BMPs as potent tumour promoters. Many of these complexities are becoming illuminated by understanding the role of BMPs in their contextual role in unique cell types of cancer and the impact of their surrounding tumour microenvironment. Here we review the emerging roles of BMP signalling in cancer, with a focus on the molecular underpinnings of BMP signalling in individual cancers as a valid therapeutic target for cancer prevention and treatment.
Regulation of the ALK1 ligands, BMP9 and BMP10
Authors: Li Wei , Salmon Richard M. , Jiang He , Morrell Nicholas W. 
Published: August 2016

Bone morphogenetic protein (BMP)9 and BMP10 are high affinity ligands for activin receptor-like kinase 1 (ALK1), a type I BMP receptor mainly expressed on vascular endothelial cells (ECs). ALK1-mediated BMP9/BMP10 signalling pathways have emerged as essential in EC biology and in angiogenesis. Several genetic mutations in the genes encoding the ligands and receptors of this pathway have been reported in two cardiovascular diseases, pulmonary arterial hypertension (PAH) and hereditary haemorrhagic telangiectasia (HHT). Administration of recombinant BMP9 reverses experimental PAH in preclinical rodent models. Dalantercept, an Fc-fusion protein of the extracellular domain of ALK1 and a ligand trap for BMP9 and BMP10, is in phase II clinical trials for anti-tumour angiogenesis. Understanding the regulation of BMP9 and BMP10, at both gene and protein levels, under physiological and pathological conditions, will reveal essential information and potential novel prognostic markers for the BMP9/BMP10-targeted therapies.
Ultrathin flat microwave transmitarray antenna for dual‐polarised operations
Authors: Chen Lv‐Wei , Ge Yuehe , Bird Trevor S. 
Published: August 2016

A dual‐polarised phase‐correcting microwave transmitarray that is based on an ultrathin phase‐shifting surface (PSS) has been developed at 22 GHz. The FSS element in this array has a square shape with the rotationally symmetrical geometry. It consists of two identical metallic layers etched on the two sides of a single dielectric layer. A phase‐shifting range of about 330° is achieved. A planar slot‐fed patch antenna was developed as the feed source for the compact structure. The transmitarray prototype, which is fed by a planar antenna, as well as a standard horn, was measured separately. The results show that peak gains of 25.82 and 27.45 dBi and 1 dB gain bandwidths of 6.8 and 9.5% are achieved for the two feed cases.
