Point-of-care molecular diagnostics can provide efficient and cost-effective medical care and they have the potential to fundamentally change our approach to global health. However, most existing approaches are not scalable to include multiple biomarkers. As a solution, we have combined commercial flat panel OLED display technology with protein microarray technology to enable high-density fluorescent, programmable, multiplexed biorecognition in a compact and disposable configuration with clinical-level sensitivity. Our approach leverages advances in commercial display technology to reduce pre-functionalized biosensor substrate costs to pennies per cm2. Here, we demonstrate quantitative detection of IgG antibodies to multiple viral antigens in patient serum samples with detection limits for human IgG in the 10 pg/mL range. We also demonstrate multiplexed detection of antibodies to the HPV16 proteins E2, E6 and E7, which are circulating biomarkers for cervical as well as head and neck cancers.

Light chain (AL) amyloidosis, caused by deposition of amyloidogenic immunoglobulin light chains (LCs), is the most common systemic form in industrialized countries. Still open questions, and premises for developing targeted therapies, concern the mechanisms of amyloid formation in vivo and the bases of organ targeting and dysfunction. Investigating amyloid material in its natural environment is crucial to obtain new insights on the molecular features of fibrillar deposits at individual level. To this aim, we used Fourier transform infrared (FTIR) microspectroscopy for studying in situ unfixed tissues (heart and subcutaneous abdominal fat) from patients affected by AL amyloidosis. We compared the infrared response of affected tissues with that of ex vivo and in vitro fibrils obtained from the pathogenic LC derived from one patient, as well as with that of non amyloid-affected tissues. We demonstrated that the IR marker band of intermolecular β-sheets, typical of protein aggregates, can be detected in situ in LC amyloid-affected tissues, and that FTIR microspectroscopy allows exploring the inter- and intra-sample heterogeneity. We extended the infrared analysis to the characterization of other biomolecules embedded within the amyloid deposits, finding an IR pattern that discloses a possible role of lipids, collagen and glycosaminoglycans in amyloid deposition in vivo.

Published: July 2016

Mutation of FAM134B (Family with Sequence Similarity 134, Member B) leading to loss of function of its encoded Golgi protein and has been reported induce apoptosis in neurological disorders. FAM134B mutation is still unexplored in cancer. Herein, we studied the DNA copy number variation and novel mutation sites of FAM134B in a large cohort of freshly collected oesophageal squamous cell carcinoma (ESCC) tissue samples. In ESCC tissues, 37% (38/102) showed increased FAM134B DNA copies whereas 35% (36/102) showed loss of FAM134B copies relative to matched non-cancer tissues. Novel mutations were detected in exons 4, 5, 7, 9 as well as introns 2, 4-8 of FAM134B via HRM (High-Resolution Melt) and Sanger sequencing analysis. Overall, thirty-seven FAM134B mutations were noted in which most (31/37) mutations were homozygous. FAM134B mutations were detected in all the cases with metastatic ESCC in the lymph node tested and in 14% (8/57) of the primary ESCC. Genetic alteration of FAM134B is a frequent event in the progression of ESCCs. These findings imply that mutation might be the major driving source of FAM134B genetic modulation in ESCCs.
Revealing the morphological architecture of a shape memory polyurethane by simulation

Published: July 2016

The lack of specific knowledge of the network structure in shape memory polymers (SMPs) has prevented us from gaining an in-depth understanding of their mechanisms and limited the potential for materials innovation. This paper firstly reveals the unit-cell nanoscale morphological architecture of SMPs by simulation. The phase separated architecture of a segmented shape memory polyurethane (SMPU) with a 30 wt% hard segment content (HSC, 4,4’-diphenylmethane diisocyanate (MDI) and 1,4-butanediol (BDO)) showing good shape memory properties was investigated by dissipative particle dynamics (DPD) simulations. A linked-spherical netpoint-frame phase of MDI, a matrix-switch phase of polycaprolactone (PCL) and a connected-spider-like interphase for BDO were obtained for this SMPU. The BDO interphase can reinforce the MDI network. Based on these simulation results, a three-dimensional (3D) overall morphological architectural model of the SMPU can be established. This theoretical study has verified, enriched and integrated two existing schematic models: one being the morphological model deduced from experiments and the other the frame model for SMPs reported before. It can serve as a theoretical guide for smart polymeric materials design. This method for the simulation of polymer structure at the nanoscale can be extended to many areas such as photonic crystals where nanoscale self-assembly plays a vital role.
More than carbon sequestration: Biophysical climate benefits of restored savanna woodlands
Authors: Syktus Jozef I. , McAlpine Clive A.
Published: July 2016

Deforestation and climate change are interconnected and represent major environmental challenges. Here, we explore the capacity of regional-scale restoration of marginal agricultural lands to savanna woodlands in Australia to reduce warming and drying resulting from increased concentration of greenhouse gases. We show that restoration triggers a positive feedback loop between the land surface and the atmosphere, characterised by increased evaporative fraction, eddy dissipation and turbulent mixing in the boundary-layer resulting in enhanced cloud formation and precipitation over the restored regions. The increased evapotranspiration results from the capacity deep-rooted woody vegetation to access soil moisture. As a consequence, the increase in precipitation provides additional moisture to soil and trees, thus reinforcing the positive feedback loop. Restoration reduced the rate of warming and drying under the transient increase in the radiative forcing of greenhouse gas emissions (RCP8.5). At the continental scale, average summer warming for all land areas was reduced by 0.18 oC from 4.1 oC for the period 2056–2075 compared to 1986–2005. For the restored regions (representing 20% of Australia), the averaged surface temperature increase was 3.2 °C which is 0.82 °C cooler compared to agricultural landscapes. Further, there was reduction of 12% in the summer drying of the near-surface soil for the restored regions.
Role of Yb3+ ions on enhanced ~2.9 μm emission from Ho3+ ions in low phonon oxide glass system
Authors: Balaji Sathravada , Gupta Gaurav , Biswas Kaushik , Ghosh Debarati , Annapurna Kalyandurg
Published: July 2016

The foremost limitation of an oxide based crystal or glass host to demonstrate mid- infrared emissions is its high phonon energy. It is very difficult to obtain radiative mid-infrared emissions from these hosts which normally relax non-radiatively between closely spaced energy levels of dopant rare earth ions. In this study, an intense mid-infrared emission around 2.9 μm has been perceived from Ho3+ ions in Yb3+/Ho3+ co-doped oxide based tellurite glass system. This emission intensity has increased many folds upon Yb3+: 985 nm excitation compared to direct Ho3+ excitations due to efficient excited state resonant energy transfer through Yb3+: 2F5/2 → Ho3+: 5I5 levels. The effective bandwidth (FWHM) and cross-section (σem) of measured emission at 2.9 μm are assessed to be 180 nm and 9.1 × 10−21 cm2 respectively which are comparable to other crystal/glass hosts and even better than ZBLAN fluoride glass host. Hence, this Ho3+/Yb3+ co-doped oxide glass system has immense potential for the development of solid state mid-infrared laser sources operating at 2.9 μm region.
An Artificial Reaction Promoter Modulates Mitochondrial Functions via Chemically Promoting Protein Acetylation
Authors: Shindo Yutaka , Komatsu Hirokazu , Hotta Kohji , Ariga Katsuhiko , Oka Kotaro
Published: July 2016

Acetylation, which modulates protein function, is an important process in intracellular signalling. In mitochondria, protein acetylation regulates a number of enzymatic activities and, therefore, modulates mitochondrial functions. Our previous report showed that tributylphosphine (PBu3), an artificial reaction promoter that promotes acetylransfer reactions in vitro, also promotes the reaction between acetyl-CoA and an exogenously introduced fluorescent probe in mitochondria. In this study, we demonstrate that PBu3 induces the acetylation of mitochondrial proteins and a decrease in acetyl-CoA concentration in PBu3-treated HeLa cells. This indicates that PBu3 can promote the acetyltransfer reaction between acetyl-CoA and mitochondrial proteins in living cells. PBu3-induced acetylation gradually reduced mitochondrial ATP concentrations in HeLa cells without changing the cytoplasmic ATP concentration, suggesting that PBu3 mainly affects mitochondrial functions. In addition, pyruvate, which is converted into acetyl-CoA in mitochondria and transiently increases ATP concentrations in the absence of PBu3, elicited a further decrease in mitochondrial ATP concentrations in the presence of PBu3. Moreover, the application and removal of PBu3 reversibly alternated mitochondrial fragmentation and elongation. These results indicate that PBu3 enhances acetyltransfer reactions in mitochondria and modulates mitochondrial functions in living cells.
Intercellular transfer of P-glycoprotein in human blood-brain barrier endothelial cells is increased by histone deacetylase inhibitors
Authors: Noack Andreas , Noack Sandra , Buettner Manuela , Naim Hassan Y. , Löscher Wolfgang
Published: July 2016

The blood–brain barrier (BBB) controls the entry of compounds into the brain, thereby regulating brain homeostasis. Efflux transporters such as P-glycoprotein (Pgp) significantly contribute to BBB function. Multiple signaling pathways modulate the expression and activity of Pgp in response to xenobiotics and disease. A non-genetic way of intercellular transfer of Pgp occurs in cancer cells, but whether this also occurs in non-cancer cells such as endothelial cells that form the BBB is not known. A human brain endothelial cell line (hCMEC/D3) was used to study whether cell-to-cell Pgp transfer occurs during co-culturing with Pgp-EGFP expressing hCMEC/D3 cells. The Pgp-EGFP fusion protein was transferred from donor to recipient cells by cell-to-cell contact and Pgp-EGFP enriched vesicles, which were exocytosed by donor cells and endocytosed by adherent recipient cells. Flow cytometry experiments with the Pgp substrate eFLUXX-ID Gold demonstrated that the transferred Pgp is functional in the recipient cells. Exposure of the donor cells with inhibitors of histone deacetylases (HDACs) resulted in an enhanced intercellular Pgp transfer. Non-genetic transfer of a resistance phenotype and its regulation by HDACs is a novel mechanism of altering BBB functionality. This mechanism may have important implications for understanding drug-induced alterations in Pgp expression and activity.
2-Aminoethoxydiphenyl Borate Potentiates CRAC Current by Directly Dilating the Pore of Open Orai1

Published: July 2016

2-Aminoethoxydiphenyl borate (2-APB) elicits potentiation current (Ip) on Ca2+ release-activated Ca2+ (CRAC) channels. An accurate investigation into this modulation mechanism would reveal how STIM1-dependent channel gating is enhanced and benefit the future immune enhancer development. Here, we directly probed the pore diameter of CRAC channels and found that 2-APB enlarged the pore size of STIM1-activated Orai1 from 3.8 to 4.6 Å. We demonstrated that ions with small sizes, i.e., Ca2+ and Na+, mediated prominent 2-APB-induced Ip on the wildtype (WT) Orai1 channels of narrow pore sizes, while conducted decreased or no Ip on Orai1-V102C/A/G mutant channels with enlarged pore diameters. On the contrary, large Cs+ ions blocked the WT channels, while displayed large 2-APB induced Ip on pore-enlarged Orai1-V102C/A/G mutant channels and the potentiation ratio was highest on Orai1-V102C with an intermediate pore size. Furthermore, we showed that 2-APB potentiated Cs+ current on constitutively active Orai1-V102C/A/G mutants independent of STIM1. Our data suggest that 2-APB directly dilates the pore of open Orai1 channels, both ion size and pore diameter jointly determine the amplitude of Ip on CRAC channels and the generation of Ip requires the open state of Orai1, not STIM1 itself.

Currently, an anti-glycopeptidolipid (GPL)-core IgA antibody assay kit for diagnosing Mycobacterium avium complex (MAC) is commercially available. We conducted this systematic review and meta-analysis to reveal the precise diagnostic accuracy of anti-GPL-core IgA antibodies for MAC pulmonary disease (MAC-PD). We systematically searched reports that could provide data for both sensitivity and specificity by anti-GPL-core IgA antibody for clinically diagnosed MAC-PD. Diagnostic test accuracy was estimated using the bivariate model. Of the 257 articles that we had found through primary search, we finally included 16 reports consisted of 1098 reference positive subjects and 2270 reference negative subjects. The diagnostic odds ratio was 24.8 (95% CI 11.6–52.8, I2 = 5.5%) and the area under the hierarchical summary receiver operating characteristic curves was 0.873 (95% CI 0.837–0.913). With a cutoff value of 0.7 U/mL, the summary estimates of sensitivity and specificity were 0.696 (95% CI 0.621–0.761) and 0.906 (95% CI 0.836–0.951), respectively. The positive and negative likelihood ratios were 7.4 (95% CI 4.1–13.8) and 0.34 (95% CI 0.26–0.43), respectively. The demanding clinical diagnostic criteria may be a cause of false positive of the index test. The index test had good overall diagnostic accuracy and was useful to ruling in MAC-PD with the cutoff value.

Published: July 2016

Environmental contextDissolved organic nitrogen often constitutes the largest portion of the dissolved nitrogen pool yet is a commonly overlooked nutrient source in aquatic systems. Terrestrially aged Eucalyptus camaldulensis, a common lowland leaf litter species, rapidly released proteinaceous dissolved organic nitrogen during the first 24h of leaching. The results indicate that terrestrial leaf litter may play an important role in satisfying nutrient demand within aquatic systems through both direct deposition and floodplain interactions. AbstractUnderstanding sources and forms of dissolved nitrogen is of critical importance to the management of aquatic systems worldwide. Dissolved organic nitrogen (DON) often constitutes the largest portion of the dissolved nitrogen pool, yet is commonly overlooked as a nutrient source to aquatic food webs, likely owing to its bound nature within organic material and the non-specific methods by which it is measured. In this study, we determined the protein and peptide (dissolved combined amino acid (DCAA)) contribution to DON leached from Eucalyptus camaldulensis leaves over 24h. The distribution of proteinaceous material in unleached and leached leaves was characterised using Fourier-transform infrared (FTIR) microspectroscopy to determine the likely source of DCAA within the leaf tissue. DCAAs were found to be a significant component (38.5%) of the leached DON; however, >90% of the leaf protein remained in the leaves after 24h. FTIR microspectroscopy shows that proteinaceous material is strongly partitioned to fungal colonised palisade cells in the leaf mesophyll, with evidence for depletion of this material after leaching. Comparison of leaching kinetics in the presence and absence of a microbial inhibitor (sodium azide) suggests that microbial uptake or adsorption commences within the timescales of these leaching experiments. The work shows that DON in the form of peptides and proteins leached from leaf litter is a likely source of bioavailable nutrients to in-stream and floodplain systems.
The impact of aging on laboratory fire behaviour in masticated shrub fuelbeds of California and Oregon, USA

Published: July 2016

Mastication of shrubs and small trees to reduce fire hazard has become a widespread management practice, yet many aspects of the fire behaviour of these unique woody fuelbeds remain poorly understood. To examine the effects of fuelbed aging on fire behaviour, we conducted laboratory burns with masticated Arctostaphylos spp. and Ceanothus spp. woody debris that ranged from 2 to 16 years since treatment. Masticated fuels that were 10 years or older burned with 18 to 29% shorter flame heights and 19% lower fireline intensities compared with the younger fuelbeds across three different fuel loads (25, 50 and 75 Mg ha–1). Older fuelbeds smouldered for almost 50% longer than the younger masticated fuelbeds. Fuel consumption was 96% in the two higher fuel load categories regardless of fuelbed age, whereas consumption was 77% in the lighter fuel load. Fire intensity in masticated fuels may decrease over time owing to particle degradation, but in dry environments where decomposition is slow, combustion of the remaining fuels may still pose risks for tree mortality and smoke production associated with protracted smouldering.
Live-capture of feral cats using tracking dogs and darting, with comparisons to leg-hold trapping

Context Predation by feral cats is a key threatening process to many species of native Australian wildlife. Unfortunately, cats are difficult to capture using standard trapping techniques, limiting the potential to conduct research on their ecology and impacts. Aims We present an alternative capture method: remote chemical immobilisation after tracking with trained dogs. We also compare capture rates to a concurrent soft-jaw leg-hold trapping program. Methods We used dogs to capture cats detected by spotlighting at night, and also recaptured cats fitted with telemetry collars during the day. Cats were either bailed on the ground or treed and then hand-netted, or chemically immobilised using darts shot from a CO2-powered dart rifle, loaded with tiletamine–zolazepam at ~6 mg kg–1. Factors affecting the success rate of capturing cats using dogs were assessed. Efficiency in terms of cats captured per person-hours of fieldwork were compared using trained dogs versus leg-hold trapping. Key results We attempted 160 cat captures using the tracking dogs with 114 of those being successful. There were no mortalities or debilitating physical injuries associated with chemical immobilisation; however, sedated cats had prolonged recoveries (>4 h). Capture success with the tracking dogs increased as the dogs gained experience. Capture success rates per person-hour of fieldwork were four times greater using spotlighting with tracking dogs than using leg-hold traps. The success rate of recaptures using dogs was 97%. Conclusions The use of trained tracking dogs proved an effective method for capturing feral cats. The method had a much higher success rate than live-trapping with leg-hold traps, took less effort (in terms of person-hours) and caused less physical injuries than did leg-hold traps. However, substantial setup costs and time are required, which are discussed. Implications Using these methods could improve efficiency and outcomes when catching feral cats, and enable more data per individual cat to be collected than otherwise.
Address pronouns in French
Authors: Warren Jane
Published: July 2016

This article examines speakers’ perceptions of and attitudes towards address pronoun usage in Paris and Toulouse. The data on which this article is based come from a comparative project based at the University of Melbourne,Address in some western European languages, and were generated in focus groups in both Paris and Toulouse, as well as interviews in Paris. It is generally accepted that in France the informal pronominal address formtuis used within the family, with close friends and with youngsters, and that the formal address formvousis used by adults when addressing strangers. The findings presented here indicate that, outside these general tendencies, individual preferences and negotiation can inform the choice of address pronoun in different ways both within and outside the workplace, with individual variation more common outside the work domain.
Pronominal address in German
Authors: Kretzenbacher Heinz L. , Clyne Michael , Schüpbach Doris
Published: July 2016

Choice of address forms, a socially crucial feature in German communication, is context-dependent on situations (a) where the unmarked form of address isdu(T), (b) where it isSie(V), and (c) where the two systems (a and b) coexist. The first two situations are, apart from their fuzzy edges, rather clearcut. The third situation, however, appears anarchic and has a high embarrassment potential. In an empirical study based on 72 interviews conducted in three regions of the German speaking area, the three prototypical situations are explored. A number of potentially conflicting rules and preferences for ambiguity are isolated. These include individual preferences, network preferences and perceptions of social distance, based on factors such as relative age, emotional closeness of interlocutors, and perceived commonalities between them. In spite of the complex interplay of competing rules and preferences and the consequent embarrassment potential, German speakers appear to reject any imposition from outside of a particular address form. This study is part of a larger, Australian-based project comparing the address systems of French, German and Swedish.
Are we making a difference?
Authors: Clyne Michael
Published: July 2016

Language is crucial in our lives and to all disciplines. It affects our well-being individually and collectively and touches important sociopolitical issues. Linguists/applied linguists have exciting opportunities for interdisciplinary research and to work in contexts personally meaningful to them. While language is the concern of all people, professionals have special responsibilities to provide leadership in understanding how it works and responsible insights into the uses and abuses of language in society.

Australian language specialists can offer the rest of the world experience with language policy, typological and language contact studies, and bilingual language acquisition. Some Australians have advanced linguistic knowledge through studies of indigenous languages. Many have worked with indigenous, ethnic and other communities and professional groups, providing evidence in court or advice to teachers and families. Some broadcast regularly or occasionally. But have we succeeded in contesting the monolingual mindset of the mainstream? The Australian authors represented in language sections of most general bookshops are not linguists.

Far more collaboration and coordination of initiatives through the professional societies is needed to put languages back on the national agenda and make Australia more language-aware. This should lead to recognizing, valuing, fostering and transmitting, supporting and sharing our linguistic diversity. Australia’s rich language potential has only been partly realized.
How are we to understand the ‘intercultural dimension’?
Authors: Crichton Jonathan , Scarino Angela
Published: July 2016

The internationalisation of education has become a major focus of international, national and institutional attention, reflected in a substantial and expanding literature on how internationalisation is manifested, how it might be promoted, its implications for areas such as government policy, strategic planning and management, educational quality, student mobility, teaching and learning, and the place of language and culture in teaching and learning. There is also general agreement in the literature on the need for internationalisation to include an ‘intercultural dimension’.

In this paper, we examine how we are to understand the ‘intercultural dimension’ in higher education. Our approach is based on an analysis of current constructions of this dimension, to argue that these constructions are neither individually nor in combination capable of meeting the challenge of internationalisation. Drawing on recent studies undertaken at the University of South Australia, we propose culture as ‘intercultural’ as an alternative construction.
