Published: June 2019

AbstractData collection by conservation biologists is undergoing radical change, with researchers collaborating across disciplines to create bespoke, low‐cost monitoring equipment from open‐source hardware (OSH). Compared to commercial hardware, OSH dramatically reduces participation costs. Four barriers currently hold back its wide adoption: (1) user inexperience inhibits initial uptake; (2) complex and costly manufacturing/distribution procedures impede global dissemination; (3) lack of creator support results in lapsed projects; and (4) lack of user support degrades continued utility in the field. Here, we propose a framework to address these barriers, illustrating how OSH offers a route to rapid expansion of community‐driven conservation action.

AbstractBasal stem rot disease caused by the white‐rot fungus Ganoderma boninense is a major threat to the oil palm industry, and hence, the ability to detect infections at an early stage of development is desired. In this study, a headspace solid‐phase microextraction (HS‐SPME) method coupled with gas chromatography–mass spectrometry (GC‐MS) was employed to analyse the volatile organic compounds (VOCs) released from G. boninense cultures and infected oil palm wood. We examined VOCs released from three types of samples: G. boninense mycelium, oil palm wood and oil palm wood colonized by G. boninense. This preliminary study led to the tentative identification of 57 VOCs, including alcohols, alkanes, volatile acids, ketones, aldehydes, esters, sesquiterpenes and polycyclic aromatic hydrocarbon groups. Aliphatic compounds with eight‐carbon atoms, such as 1‐octen‐3‐ol, 3‐octanone, 1‐octanol and (E)‐2‐octenal, were the most abundant constituents of the Ganoderma samples, whereas furfural and hexanal were the major compounds detected in the oil palm wood samples. Chemometric analyses using cluster heat maps and principal component analyses were used to discriminate between the VOC profiles. The results indicated that the novel method described here could be used to detect Ganoderma disease and, more generally, for chemoecological studies of plant–pathogen interactions.

AbstractAimThis paper outlines the transformation of youth mental health services in Edmonton, Alberta, a large city in Western Canada. We describe the processes and challenges involved in restructuring how services and care are delivered to youth (11‐25 years old) with mental health needs based on the objectives of the pan‐Canadian ACCESS Open Minds network.MethodsWe provide a narrative review of how youth mental health services have developed since our engagement with the ACCESS Open Minds initiative, based on its five central objectives of early identification, rapid access, appropriate care, continuity of care, and youth and family engagement.ResultsBuilding on an initial community mapping exercise, a service network has been developed; teams that were previously age‐oriented have been integrated together to seamlessly cover the age 11 to 25 range; early identification has thus far focused on high‐school populations; and an actual drop‐in space facilitates rapid access and linkages to appropriate care within the 30‐day benchmark.ConclusionsInitial aspects of the transformation have relied on restructuring and partnerships that have generated early successes. However, further transformation over the longer term will depend on data demonstrating how this has impacted clinical outcomes and service utilization. Ultimately, sustainability in a large urban centre will likely involve scaling up to a network of similar services to cover the entire population of the city.

AbstractAimIn many parts of the world, there is growing concern about youth homelessness. Homeless youth are particularly vulnerable to psychological distress, substance use and mental disorders, and premature mortality caused by suicide and drug overdose. However, their access to and use of mental health care is very limited.MethodsThe Réseau d'intervention de proximité auprès des jeunes (RIPAJ), a Montreal network of over 20 community stakeholders providing a wide array of cohesive services, was created to ease homeless youth's access to mental health and psychosocial services. Its philosophy is that there should be no “wrong door” or “wrong timing” for youth seeking help. In 2014, the network partnered with the pan‐Canadian transformational research initiative, ACCESS Esprits ouverts.ResultsCreated through this partnership, ACCESS Esprits ouverts RIPAJ has been promoting early identification through outreach activities targeting homeless youth and agencies that serve them. An ACCESS Clinician was hired to promote and rapidly respond to help‐seeking and referrals. By strengthening connections within RIPAJ and using system navigation, the site is working to facilitate youth's access to timely appropriate care and eliminate age‐based transitions between services. A notable feature of our program, that is not usually evident in homelessness services, has been the engagement of the youth in service planning and design and the encouragement of contact with families and/or friends.ConclusionChallenges remain including eliminating any remaining age‐related transitions of care between adolescent and adult services; and the sustainability of services transformation and network coordination. Nonetheless, this program serves as an example of an innovative, much‐needed, community‐oriented model for improving access to mental health care for homeless youth.

AbstractAimThis paper describes how the transformation of youth mental health services in the rural Francophone region of the Acadian Peninsula in New Brunswick, Canada, is meeting the five objectives of ACCESS Open Minds.MethodsImplementation of the ACCESS Open Minds framework of care in the Acadian Peninsula of New Brunswick began in 2016 at a well‐established volunteer centre and community‐based mental health organization. Through focus groups with youth aged 14 to 22 (n = 13), community mapping was used to describe the youth‐related mental health service transformation, followed by thematic analysis, validation by member checking and triangulation.ResultsPreliminary results show a generally successful implementation of the ACCESS Open Minds model, as evidenced by the transformation of mental health service provision, the enhancement of capacity in human resources and the participation of youth. Transformation was evidenced across the five objectives of mental healthcare of ACCESS Open Minds, albeit to variable extents. Several facilitating factors and challenges are identified based on youths' accounts.ConclusionsIt is possible to successfully implement the ACCESS Open Minds model among francophones living in a minority setting and despite the constraints of a rural area. Most key components of the framework were implemented with high program fidelity. The rural context presents unique challenges that require creative and effective use of resources, while offering opportunities that arise from a culture of resourcefulness and collaboration.

AbstractAimDemands for mental health services in post‐secondary institutions are increasing. This paper describes key features of a response to these needs: ACCESS Open Minds University of Alberta (ACCESS OM UA) is focused on improving mental health services for first‐year students, as youth transition to university and adulthood.MethodsThe core transformation activities at ACCESS OM UA are described, including early case identification, rapid access, appropriate and timely connections to follow‐up care and engagement of students and families/carers. In addition, we depict local experiences of transforming existing services around these objectives.ResultsThe ACCESS OM UA Network has brought together staff with diverse backgrounds in order to address the unique needs of students. Together with the addition of ACCESS Clinicians these elements represent a systematic effort to support not just mental health, but the student as a whole. Key learnings include the importance of community mapping to developing networks and partnerships, and engaging stakeholders from design through to implementation for transformation to be sustainable.ConclusionsService transformation grounded in principles of community‐based research allows for incorporation of local knowledge, expertise and opportunities. This approach requires ample time to consult, develop rapport between staff and stakeholders across diverse units and develop processes in keeping with local opportunities and constraints. Ongoing efforts will continue to monitor changing student needs and to evaluate and adapt the transformations outlined in this paper to reflect those needs.
Light‐induced complex formation of bacteriophytochrome RpBphP1 and gene repressor RpPpsR2 probed by SAXS

Published: June 2019

Bacteriophytochrome proteins (BphPs) are molecular light switches that enable organisms to adapt to changing light conditions through the control of gene expression. Canonical type 1 BphPs have histidine kinase output domains, but type 3 RpBphP1, in the bacterium Rhodopseudomonas palustris (Rps. palustris), has a C terminal PAS9 domain and a two‐helix output sensor (HOS) domain. Type 1 BphPs form head‐to‐head parallel dimers; however, the crystal structure of RpBphP1ΔHOS, which does not contain the HOS domain, revealed pseudo anti‐parallel dimers. HOS domains are homologs of Dhp dimerization domains in type 1 BphPs. We show, by applying the small angle X‐ray scattering (SAXS) technique on full‐length RpBphP1, that HOS domains fulfill a similar role in the formation of parallel dimers. On illumination with far‐red light, RpBphP1 forms a complex with gene repressor RpPpsR2 through light‐induced structural changes in its HOS domains. An RpBphP1:RpPpsR2 complex is formed in the molecular ratio of 2 : 1 such that one RpBphP1 dimer binds one RpPpsR2 monomer. Molecular dimers have been modeled with Pfr and Pr SAXS data, suggesting that, in the Pfr state, stable dimeric four α‐helix bundles are formed between HOS domains, rendering RpBphP1functionally inert. On illumination with light of 760 nm wavelength, four α‐helix bundles formed by HOS dimers are disrupted, rendering helices available for binding with RpPpsR2.

Published: June 2019

The large range of stable oxygen isotope values of phosphate‐bearing minerals and dissolved phosphate of inorganic or organic origin requires the availability of in‐house produced calibrated silver phosphate of which isotopic ratios must closely bracket those of studied samples. We propose a simple protocol to synthesise Ag3PO4 in a wide range of oxygen isotope compositions based on the equilibrium isotopic fractionation factor and the kinetics and temperature of isotopic exchange in the phosphate–water system. Ag3PO4 crystals were obtained from KH2PO4 that was dissolved in water of known oxygen isotope composition. Isotopic exchange between dissolved phosphate and water took place at a desired and constant temperature into PYREX™ tubes that were placed in a high precision oven for defined run‐times. Samples were withdrawn at desired times, quenched in cold water and precipitated as Ag3PO4. We provide a calculation sheet that computes the δ18O of precipitated Ag3PO4 as a function of time, temperature and δ18O of both reactants KH2PO4 and H2O at t = 0. Predicted oxygen isotope compositions of synthesised silver phosphate range from −7 to +31‰ VSMOW for a temperature range comprised between 110 and 130 °C and a range of water δ18O from −20 to +15‰ VSMOW.

Published: June 2019

AbstractStereolithography is an attractive technique for the fabrication of complex‐shaped ceramic components with high dimensional accuracy. One of the challenges in this technology is the development of high solid loading, low viscosity photosensitive ceramic suspension. In this study, the dispersion of zirconia in photocurable resin and the slurry properties were intensively investigated. Rheological measurements showed that DISPERBYK‐103 proved to be an effective dispersant. 42 vol% ZrO2suspension was successfully prepared using 3.5 wt% DISPERBYK‐103 as the dispersant, with a suitable viscosity (4.88 Pa·s) below the maximum allowable viscosity value (5 Pa·s) for stereolithography applications. The adsorption behavior of DISPERBYK‐103 on the surface of zirconia powders was characterized by TG and FT‐IR, confirming the dispersion effect of dispersant. Contact angle measurements were also conducted to show that the adsorption of DISPERBYK‐103 could help to improve the wettability between powder and photocurable resin. Results showed that DISPERBYK‐103 was effective for the preparation of suitable slurries for the development of ZrO2ceramics through stereolithography.

SummaryMango by‐products are considered cheap sources of valuable foods and nutraceutical ingredients. In this work, antioxidant capacity (AOX), and potential absorption ability (PAA) of extractable polyphenols (EP) from mango by‐product snacks (MB‐S) were evaluated at different stages of in vitro gastrointestinal digestion. A wheat and oat‐based control snack and three MB‐S formulations (F1, F2 and F3) were prepared. Mango by‐products were added at the expense of wheat in MB‐S (paste‐peel‐seed): F1 (70‐30‐0), F2 (70‐15‐15), F3 (70‐7.5‐22.5). The highest release of polyphenols was observed after the gastric digestion. In the intestinal stage, MB‐SF1 was the snack with the highest EP content (23.39 mg GAE/g db), two times greater than the control. Gallic acid and mangiferin were the main polyphenols identified in MB‐S. The incorporation of mango seed in the MB‐S reduced the polyphenols PAA by 10.29%. However, compared with the control snack, consumption of 30 g MB‐SF1 provided additional 45 mg polyphenols.

SummaryThe objective of this study was to determine the efficacy of supercritical carbon dioxide turmeric extract (STE) on the oxidative stability of perilla oil (PO), as measured by acid value (AV), peroxide value (PV) and oxidation induction time and compared to control and α‐tocopherol containing PO as a positive control. The antioxidant activity was determined by DPPH, ABTS and FRAPS assays and individual bioactive compounds identified by chromatography. STE demonstrated significantly higher antioxidant activity than the α‐tocopherol. The major components of the STE were identified as ar‐turmerone, turmerone, curlone and bisabolene by GC‐MS and curcumin and demethoxycurcumin by UPLC‐Q‐TOF MS. During thermal treatment at 65 °C for 24 h, the PO containing STE at different concentrations (100, 300, 500 and 1000 μg mL−1) had significantly lower AV and PV, and at least 1.5 times higher induction period than those of the control and α‐tocopherol‐incorporated PO.
Uniform colloidal spheres for RE3BO6 (RE = Eu‐Yb, Y) and excitation‐dependent luminescence of Y3BO6:Eu3+ red phosphor

AbstractPhosphor particles of spherical shape and uniform size are desired for high‐definition displays to improve the resolution and the overall luminescent performance. However, the synthesis of RE3BO6 spherical particles is a considerable challenge in materials science. Here, uniform spheres of RE3BO6 (RE = Eu–Yb, Y) have been converted from their colloidal precursor spheres synthesized via homogeneous precipitation. The amorphous precursor spheres are solid particles with decreased boron going from the surfaces to the cores. Smaller particles were observed at decreased ionic radius from Eu3+ to Ho3+ (including Y3+), but particles with nearly unvaried sizes were observed by further decreasing the ionic radius from Ho3+ to Yb3+. They crystallized in monoclinic RE3BO6 at 900°C, with maintaining the spherical shape of precursors. However, the crystal growth and the densification toward the particle surfaces resulted in the formation of hollow spheres for smaller particles and core‐shell structured spheres for larger particles. The parameters, a, b, and c, increase nearly monotonically with increasing the radius of rare earth ions. The uniform spheres of Y3BO6:Eu3+ exhibited a typical red emission at ~613 nm (5D0 → 7F2 electric dipole transition of Eu3+), with an intensity ratio I(5D0 → 7F2)/I(5D0 → 7F1) of ~3.5. The luminescence behavior of Y3BO6:Eu3+ phosphor is dependent on the excitation wavelength, which is closely related to the Eu3+ ions at different coordination sites. Driven by a 460‐nm blue‐LED chip, the Y3BO6:Eu3+ spheres exhibited a red emission with the CIE coordinates of (~0.65, ~0.35), indicating that they are an excellent red‐emitting phosphor candidate for application in white‐LEDs.

AbstractBackgroundIn Europe, one of the highest melanoma incidences is found in the Netherlands. Like in several other European countries, females are more prone to develop melanoma as compared to males, although survival is worse for men.ObjectiveTo identify clinicopathological gender‐related differences that may lead to gender‐specific preventive measures.MethodsData from the Dutch Nationwide Network and Registry of Histopathology and Cytopathology (PALGA) were retrieved from patients with primary, cutaneous melanoma in the Netherlands between 2000 and 2014. Patients initially presenting as stage I, II and III without clinically detectable nodal disease were included. Follow‐up data were retrieved from the Netherlands Cancer Registry. Gender‐related differences were assessed, and to compare relative survival between males and females, multivariable relative excess risks (RER) were calculated.ResultsA total of 54.645 patients were included (43.7% men). In 2000, 41.7% of the cohort was male, as compared to 47.3% in 2014 (P < 0.001). Likewise, in 2000, 51.5% of the deceased cohort was male compared to 60.1% in 2014 (P < 0.001). Men had significantly thicker melanomas at the time of diagnosis [median Breslow thickness 1.00 mm (interquartile range (IQR): 0.60–2.00) vs. 0.82 mm (IQR: 0.50–1.50) for females] and were significantly older at the time of diagnosis, more often had ulcerated melanomas and melanomas localized on the trunk or head and neck. Over time, survival for females improved while that of men decreased (P < 0.001). RER for dying was 1.37 (95% CI: 1.31–1.45) for men in multivariable analysis.ConclusionThere are evident clinicopathological differences between male and female melanoma patients. After multivariable correction for all these differences, relative survival remains worse for men. Clinicians as well as persons at risk for melanoma should be aware of these differences, as awareness and prevention might lead to a lower incidence and mortality of melanoma. This indicates the need of prevention campaigns integrating and targeting specific risk profiles.
Internal and External Factors Underlying Variations in Adolescents’ Daily Optimal Experiences
Authors: Tavares Dionísia , Freire Teresa , Faria Susana 
Published: June 2019

This study investigated how the internal psychological states (i.e., challenge–skill perception, positive and negative affect, and effortless attention) and contextual features (i.e., activity and company) of momentary experiences relate to optimal experience in adolescents’ lives. Data were collected from 245 Portuguese adolescents (14–19 years old, 63% female) by using the experience sampling method. Multilevel modeling revealed that challenge–skill and positive affect were positively associated with optimal experience, while negative affect was negatively associated with optimal experience. Effortless attention mediated the associations between internal states and optimal experience, while activity and company only moderated some of these associations. These findings will inform practitioners about the factors that should be addressed in interventions with adolescents to promote optimal experiences in their lives.
