Authors: Tahmasebi Farshad , Hurrell Alice , Ford Amie , Gupta Manish , Geindreau Damien , Pimenta Dominic , O’Mahony Constantinos
Published: November 2017

Spontaneous coronary artery dissection is a rare but important cause of acute coronary syndrome. Its relevance for women during the puerperium mandates awareness and understanding amongst obstetric healthcare professionals. The aetiology of the increased risk in pregnancy has not been fully elucidated, but include medial eosinophilic angitis, pregnancy-induced degeneration of collagen in conjunction with the stresses of parturition, and rupture of the vasa vasorum. The risk of mortality necessitates prompt diagnosis, usually by angiography. There is no one-size-fits-all treatment; management must be individualised according to haemodynamic status and affected vessel(s) and includes conservative management, percutaneous coronary intervention, or bypass grafting. Recovery complications include extension of the haematoma or false lumen, valvular pathology secondary to ischaemia, and sudden cardiac death. Close post-operative surveillance is mandatory. We present a 41-year-old lady with post-partum spontaneous coronary artery dissection, complicated by ischaemic papillary rupture and mitral regurgitation requiring valve replacement. Additionally, we present a literature review, including guidance on management and critical analysis of potential complications.
Does Subjective SES Moderate the Effect of Money Priming on Socioeconomic System Support? A Replication of Schuler and Wänke (2016)
Authors: Crawford Jarret T. , Fournier Allison , Ruscio John
Published: November 2017

Findings that money priming increases socioeconomic system support have proven difficult to replicate. Schuler and Wänke found that subjective socioeconomic status (SES) moderates money priming effects on system justification and belief in a just world. We conducted three preregistered replications of this research, with sample sizes 3 times those of the original studies. Replication 1 was a conceptual replication that combined elements from the original two studies, and Replications 2 and 3 were close replications of Studies 1 and 2, respectively. None of the four subjective SES × Money Prime interaction effects tested were statistically significant, and only one of the four survived a “small telescopes” analysis. We discuss reasons for our general failure to replicate the original findings and implications for money priming effects.

Background

Migration has been reported to be associated with higher prevalence of mental disorders and suicidal behaviour.

Aims

To examine the prevalence of emotional and behavioural difficulties, suicidal ideation and suicide attempts among migrant adolescents and their non-migrant peers.

Method

A school-based survey was completed by 11 057 European adolescents as part of the Saving and Empowering Young Lives in Europe (SEYLE) study.

Results

A previous suicide attempt was reported by 386 (3.6%) adolescents. Compared with non-migrants, first-generation migrants had an elevated prevalence of suicide attempts (odds ratio (OR) 2.08; 95% CI 1.32–3.26; P=0.001 for European migrants and OR 1.86; 95% CI 1.06–3.27; P=0.031 for non-European migrants) and significantly higher levels of peer difficulties. Highest levels of conduct and hyperactivity problems were found among migrants of non-European origin.

Conclusions

Appropriate mental health services and school-based supports are required to meet the complex needs of migrant adolescents.
Assessing the value of practice-based leg ulcer education to inform recommendations for change in practice
Authors: Mitchell Aby
Published: November 2017

The purpose of this paper is to assess the value of accredited leg ulcer education in influencing changes in practice. This is a before and after educational evaluation that adopted a qualitative survey approach of 12 primary care nurses attending the Nurse-Led Assessment and Management of Leg Ulcers accredited CPD module at a London university.

The findings revealed that 6 out of the 8 nurses who completed the final interviews were satisfied that all learning outcomes for the module had been met. All of the nurses commented they had changed at least one aspect of practice following the module with the majority stating a number of improvements had been made relating to improved knowledge, practical skills, treatment and patient concordance. The evaluation was limited to a small cohort of primary care nurses and further longitudinal research is required to investigate the effectiveness across multiple cohorts.

Micropropagation of Asparagus densiflorus via axillary shoots, indirect organogenesis and somatic embryogenesis
Authors: Pindel Anna
Published: November 2017

The present study has described a simple protocol for efficient plant regeneration of Asparagus densiflorus ‘Sprengeri’ and ‘Myriocladus’ using single-node spear explants, and indirect organogenesis via callogenesis induced on internode explants. The results showed that the genotypes ‘Sprengeri’ and ‘Myriocladus’ regenerated to complete plants via nodal cultures and callus tissue, but the plant regeneration response was higher in secondary explants on MS medium with NAA + kinetin (1+1 mg dm-3) after transfer onto a multiplication medium with IAA+BAP (1+4 mg dm-3), and then onto a rooting medium supplemented with IBA (10 mg dm-3) or NAA + kinetin (1+1 mg dm-3). Primary explants of both cultivars showed high regenerative potential (via the callus stage) on MS medium with IAA+BAP. The cultivar Sprengeri also regenerated via somatic embryogenesis. Both kinds of ‘Meyeri’ explants have a morphogenetic potential for the formation of shoots, which, however, were not capable of rooting. This confirms that the explant, genotype and culture medium are determining factors in the in vitro plant regeneration system.
Eighteen hours of salmon: On the narrativity of slow TV
Authors: Irving Dan
Published: November 2017

Slow TV programs are long, uninterrupted broadcasts of relatively mundane activities, focusing on topics ranging from train rides along the coast of Norway to the chopping, stacking, and burning of firewood. This article argues that slow TV problematizes the standard conception of narrativity, especially in terms of a conceptual narrative/non-narrative boundary. Moving away from the idea of narrative-as-concept, I argue for an understanding of narrativity more sensitive to readers’ actual experience and a further nuanced understanding of the range of weak-narrativity texts. A text deemed conceptually “non-narrative” by theorists can still be experienced as narrative by readers and/or viewers, supplementing given texts or programs with personal experiences to effectively narrativize the non-narrative; narrative, I argue, is better thought of as a state that is achieved, rather than a concept that exists within a text. The article ultimately suggests a gradient of weak narrativity in order to consider new forms of experimental narrativity without collapsing its different types.
Comparative Numerical Study of Titanium and Silver Nano-particles Migration from Nano-composite of Polystyrene into Simulants on Experimental Data Basis
Authors: Soleimani J. , Ghanbarzadeh B. , Dehghannya J. , Baheri Islami S. , Sorouraddin S.M.
Published: November 2017

Nano-titanium dioxide and nano-silver combined with polystyrene granules to form a nano-composite film. Migration assess were performed by using food simulants 3% acetic acid (indicative acidic food) and 95% ethanol (indicative fatty food) at 40°C on different times of  2, 4, 6, 8 and 10 days. It was found that nanoparticle migration rate in acidic food was higher than fatty food. Diffusion coefficients of nanoparticles into simulants were estimated by inverse simulation of the migration process using finite-element method and experimental data of varied concentration. Simulation revealed an acceptable consistency between experimental data and predicted values. The numerical results indicated that the greatest diffusion coefficient was obtained by nano-titanium (2.8E-10 to 4.1E-9 m2 s−1) in the 3% acetic acid. Results of concentration distribution confirmed a higher release rate and more uniformed distribution of nanoparticles for nano-titanium in the 3% acetic acid. It also found that in the migration process the diffusion coefficient is more important than the amount of nanoparticles concentration.
Sacro-Soundscapes: Interpreting Contemporary Ritual Performances of Sacred Music through the Case of The Passion in the Netherlands
Authors: Klomp Mirella , Barnard Marcel
Published: November 2017

is a musical practice staged in the Dutch public sphere and an example of how large, Christian musical forms in late-modern network societies moved from the church to the broader culture. Neither the classical discipline of hymnology nor the emerging discipline of Christian congregational music studies have developed theoretical concepts that serve to understand musical practices outside the ecclesial domain. The authors distinguish the emerging field of fluid ritual musical practices and reinvent the concept of sacro-soundscapes as a notion that contributes to the interpretation of these practices. They claim that, consequentially, the aforementioned disciplines are included in this field and therefore change, as well.
African swine fever (ASF) and ticks. No risk of tick-mediated ASF spread in Poland and Baltic states
Authors: Frant Maciej , Woźniakowski Grzegorz , Pejsak Zygmunt
Published: November 2017

Infectious diseases of swine, particularly zoonoses, have had a significant influence on nutritional safety and availability of pig meat as high-energy protein product since the time that pigs were domesticated back in the 7th century BC. The main sources of swine infectious diseases include the so-called primary sources (direct infection, i.e. through contact with infected and sick animals) and secondary sources (contaminated meat products, slaughter products, and vectors, including ticks). At present, the most serious epidemiological and economic threat to swine breeding in Europe is African swine fever (ASF). This disease, originally coming from Africa, is incurable and causes death of infected pigs and wild boars during 7−10 days after infection. Among the various factors that influence the spread of ASF, important role is played by ticks from the genus Ornithodoros, mainly from the species Ornithodoros moubata. Research on the ASF indicates that other species of ticks can also transmit the virus to healthy pigs in laboratory conditions. Sylvatic and domestic cycles of ASF virus transmission, which have been described so far, require further studies and updating in order to point the potential new vectors in the Caucasus and Eastern Europe affected by the ASF. Effective methods of control and biosecurity may significantly slow down the spread of ASF, which undoubtedly is a major threat to world pig production and international swine trade.
The Iconic Image in a Digital Age
Authors: Mortensen Mette , Allan Stuart , Peters Chris
Published: November 2017

This article investigates selected newspapers’ editorial mediations over contrasting perceptions regarding the significance of a controversial set of ‘iconic’ news photographs, namely images of Alan Kurdi, a three-year-old Syrian refugee, whose drowned corpse washed ashore in September, 2015. Specifically, this study examined individual editorial items, published by leading Danish, Canadian and British newspapers over a four-month period, engaging with and reflecting upon this imagery. Our analysis revealed several key deliberative features of editorial self-reflexivity, with three especially salient themes shown to be emergent across the coverage: a) instantaneousness and historical photographic precedents; b) social media’s perceived influence on photojournalism; and c) normative associations of affective qualities for this imagery. By elucidating these features of editorial self-reflexivity within a convergent digital media ecology, this article offers original insights into how and why the epistemic values governing visual communication are being reconsidered and redrawn under pressure from institutional imperatives.
Nanostructured boron compounds for cancer therapy
Authors: Zhu Yinghuai , Hosmane Narayan S.
Published: November 2017

Nanostructured boron compounds have emerged as one of the promising frontiers in boron chemistry. These species possess unique physical and chemical properties in comparison with classical small boron compounds. The nanostructured boron composites generally have large amounts of boron contents and thus have the potential to deliver significant amount of boron to the tumor cells, that is crucial for boron neutron capture therapy (BNCT). In theory, BNCT is based on a nuclear capture reaction with the 10B isotope absorbing a slow neutron to initiate a nuclear fission reaction with the release of energetic particles, such as lithium and helium (α particles), which travel the distance of around nine microns within the cell DNA or RNA to destroy it. The recent studies have demonstrated that the nanostructured boron composites can be combined with the advanced targeted drug delivery system and drug detection technology. The successful combination of these three areas should significantly improve the BNCT in cancer treatment. This mini review summarizes the latest developments in this unique area of cancer therapy.
A Soliloquy That’s Overheard or Spied on? Dramatic Techniques of Involuntary Disclosure of Secrets in The Haunted Manor by Jan Chęciński and Stanisław Moniuszko and its European Contexts
Authors: Bajer Michał
Published: November 2017

The plot of The Haunted Manor hangs on scenes in which the characters confess their secrets, try to figure out the hidden truth and invent fake secrets. This article analyzes the handling of secrets in Jan Chęciński and Stanisław Moniuszko’s famous opera, paying special attention to the problem of eavesdropping and spying. After examining Chęciński and Moniuszko’s use of the neoclassical model of the overheard soliloquy, the article assesses the relationship between the treatment of the secret in The Haunted Manor and the conventions of contemporary drama. The analysis reveals that the preoccupation with secrets not only has a significant impact on the plot and the construction of individual scenes but is also used to reach out to the world of contemporary comedy. In effect, this study rejects the description of The Haunted Manor as an artless celebration of provincial backwardness and shows that its dramatic handling of secrets is as skilful and sophisticated as one would expect from a classic operatic drama.
Regional Fish-Based Biostratigraphy of the Late Neogene and Pleistocene of Southeastern Europe
Authors: Kovalchuk О. М.
Published: November 2017

This paper presents analytical results of the study of numerous freshwater fish fossils from almost 40 localities in the territory of southeastern Europe. It has been established that freshwater fishes can be regarded as parastratigraphic group suitable for biostratigraphic studies. Ten ichthyofaunal assemblages have been distinguished and characterized in the paper. These assemblages represent successive developmental stages in freshwater fish communities within southeastern Europe during the late Miocene, Pliocene and Pleistocene. Indices of evolutionary transformations (extinction rate, origination rate, taxonomic rotation) for ichthyofaunal assemblages have been calculated, and their trend is discussed herein.
The truth is out there: the metal-π interactions in crystal of Cr(CO)3(pcp) as revealed by the study of vibrational smearing of electron density
Authors: Kovalenko Anna A. , Nelyubina Yulia V. , Korlyukov Alexander A. , Lyssenko Konstantin A. , Ananyev Ivan V.
Published: November 2017

The vibrational smearing of electron density was studied in the crystal of complex of Cr(CO)3 with [2.2]paracyclophane. The combination of theoretical and experimental methods, including periodic calculations and screening of DFT calculated and multipole-decomposed electron densities, was utilized to reveal the vibrational smearing of electron density and its influence on the multipole-constructed electron density. The multipole model, commonly used to treat the high-resolution X-ray diffraction data, was shown to be rather inaccurate in description of electron density and its vibrational smearing in metal-π complex where the interchange between diatomic interactions can occur. Namely, some bond critical points can be hidden while analyzing multipole-decomposed electron density with proved effects of vibrational smearing even if the deconvolution problem is overcome by using the invariom approach. On the contrary, the recently proposed “clouds of critical point variation” (CCPV) approach is demonstrated as the route to gather all reasonable bonding trends and to reconstruct static electron density pattern in metal-π complexes.
Infoentretenimiento y política: el caso de las elecciones de 2015 y 2016 en España / Infotainment and politics: the case of the 2015 and 2016 Spanish presidential campaigns
Authors: Alonso González Marián
Published: November 2017

Las campañas electorales de 2015 y 2016 en España han puesto de manifiesto una serie de transformaciones que afectan a la construcción del mensaje informativo y, por ende, a la práctica del periodismo político. La irrupción del infoentretenimiento en el medio televisivo, la rentabilidad económica de la política televisiva, y la versatilidad y juventud de los nuevos líderes han provocado que candidatos y asesores se concentren más en la competencia mediática que en la ideología que representan. Dar a conocer al candidato, empatizar con los votantes y llegar a públicos no interesados especialmente en política se ha convertido en  la estrategia a seguir por las formaciones políticas. Su objetivo: llevar a cabo un intercambio entre el interés informativo y conseguir el minuto de oro capaz de mejorar su imagen.
ERCC1 as predictive biomarker to platinum-based chemotherapy in adrenocortical carcinomas

Published: November 2017

Objective

Platinum-based chemotherapy (PBC) is the most effective cytotoxic treatment for advanced adrenocortical carcinoma (ACC). Excision repair cross complementing group 1 (ERCC1) plays a critical role in the repair of platinum-induced DNA damage. Two studies investigating the role of ERCC1 immunostaining as a predictive marker for the response to PBC in ACC had reported conflicting results. Both studies used the ERCC1-antibody clone 8F1 that later turned out to be not specific. The aim of this study was to evaluate the predictive role of ERCC1 with a new specific antibody in a larger series of ACC.

Design and methods

146 ACC patients with available FFPE slides were investigated. All patients underwent PBC (median cycles = 6), including cisplatin (n = 131) or carboplatin (n = 15), in most cases combined with etoposide (n = 144), doxorubicin (n = 131) and mitotane (n = 131). Immunostaining was performed with the novel ERCC1-antibody clone 4F9. The relationship between ERCC1 expression and clinicopathological parameters, as well as best objective response to therapy and progression-free survival (PFS) during PBC was evaluated.

Results

High ERCC1 expression was observed in 66% of ACC samples. During PBC, 43 patients experienced objective response (29.5%), 49 stable disease (33.6%), 8 mixed response (5.5%) and 46 progressive disease (31.5%) without any relationship with the ERCC1 immunostaining. No significant correlation was also found between ERCC1 expression and progression-free survival (median 6.5 vs 6 months,P = 0.33, HR = 1.23, 95% CI = 0.82–2.0).

Conclusion

ERCC1 expression is not directly associated with sensitivity to PBC in ACC. Thus, other predictive biomarkers are required to support treatment decisions in patients with ACC.

Published: November 2017

The Dongxiang Blue-shelled chicken is one of the most valuable Chinese indigenous poultry breeds. However, compared to the Italian native White Leghorn, although this Chinese breed possesses numerous favorable characteristics, it also exhibits lower growth performance and fertility. Here, we utilized genotyping sequencing data obtained via genome reduction on a sequencing platform to detect 100,114 single nucleotide polymorphisms and perform further biological analysis and functional annotation. We employed cross-population extended haplotype homozygosity, eigenvector decomposition combined with genome-wide association studies (EigenGWAS), and efficient mixed-model association expedited methods to detect areas of the genome that are potential selected regions (PSR) in both chicken breeds, and performed gene ontology (GO) enrichment and quantitative trait loci (QTL) analyses annotating using the Kyoto Encyclopedia of Genes and Genomes. The results of this study revealed a total of 2424 outlier loci (p-value <0.01), of which 2144 occur in the White Leghorn breed and 280 occur in the Dongxiang Blue-shelled chicken. These correspond to 327 and 94 PSRs containing 297 and 54 genes, respectively. The most significantly selected genes in Blue-shelled chicken are TMEM141 and CLIC3, while the SLCO1B3 gene, related to eggshell color, was identified via EigenGWAS. We show that the White Leghorn genes JARID2, RBMS3, GPC3, TRIB2, ROBO1, SAMSN1, OSBP2, and IGFALS are involved in immunity, reproduction, and growth, and thus might represent footprints of the selection process. In contrast, we identified six significantly enriched pathways in the Dongxiang Blue-shelled chicken that are related to amino acid and lipid metabolism as well as signal transduction. Our results also reveal the presence of a GO term associated with cell metabolism that occurs mainly in the White Leghorn breed, while the most significant QTL regions mapped to the Chicken QTL Database (GG_4.0) for the Dongxiang Blue-shelled breed are predominantly related to lesions, bone mineral content, and other related traits compared to tibia length and body weight (i.e., at 14, 28, 42, and 70 d) in the White Leghorn. The results of this study highlight differences in growth, immunity, and egg quality traits between the two breeds, and provide a foundation for the exploration of their genetic mechanisms.
Comparative Efficacy of Daratumumab Monotherapy and Pomalidomide Plus Low-Dose Dexamethasone in the Treatment of Multiple Myeloma: A Matching Adjusted Indirect Comparison
Authors: Van Sanden Suzy , Ito Tetsuro , Diels Joris , Vogel Martin , Belch Andrew , Oriol Albert
Published: November 2017

Background

Daratumumab (a human CD38-directed monoclonal antibody) and pomalidomide (an immunomodulatory drug) plus dexamethasone are both relatively new treatment options for patients with heavily pretreated multiple myeloma. A matching adjusted indirect comparison (MAIC) was used to compare absolute treatment effects of daratumumab versus pomalidomide + low-dose dexamethasone (LoDex; 40 mg) on overall survival (OS), while adjusting for differences between the trial populations.

Materials and Methods

The MAIC method reduces the risk of bias associated with naïve indirect comparisons. Data from 148 patients receiving daratumumab (16 mg/kg), pooled from the GEN501 and SIRIUS studies, were compared separately with data from patients receiving pomalidomide + LoDex in the MM-003 and STRATUS studies.

Results

The MAIC-adjusted hazard ratio (HR) for OS of daratumumab versus pomalidomide + LoDex was 0.56 (95% confidence interval [CI], 0.38–0.83; p = .0041) for MM-003 and 0.51 (95% CI, 0.37–0.69; p < .0001) for STRATUS. The treatment benefit was even more pronounced when the daratumumab population was restricted to pomalidomide-naïve patients (MM-003: HR, 0.33; 95% CI, 0.17–0.66; p = .0017; STRATUS: HR, 0.41; 95% CI, 0.21–0.79; p = .0082). An additional analysis indicated a consistent trend of the OS benefit across subgroups based on M-protein level reduction (≥50%, ≥25%, and <25%).

Conclusion

The MAIC results suggest that daratumumab improves OS compared with pomalidomide + LoDex in patients with heavily pretreated multiple myeloma.

Implications for Practice

This matching adjusted indirect comparison of clinical trial data from four studies analyzes the survival outcomes of patients with heavily pretreated, relapsed/refractory multiple myeloma who received either daratumumab monotherapy or pomalidomide plus low-dose dexamethasone. Using this method, daratumumab conferred a significant overall survival benefit compared with pomalidomide plus low-dose dexamethasone. In the absence of head-to-head trials, these indirect comparisons provide useful insights to clinicians and reimbursement authorities around the relative efficacy of treatments.
Seismic behaviour of interior reinforced-concrete beam–column sub-assemblages with engineered cementitious composites
Authors: Lee Siong Wee , Tan Kang Hai , Yang En-Hua
Published: November 2017

The feasibility of using engineered cementitious composites (ECC) in joint cores of reinforced-concrete (RC) beam–column sub-assemblages as a means to enhance seismic behaviour is evaluated. Four RC beam–column sub-assemblages are constructed and tested under lateral cyclic loading. One RC beam–column sub-assemblage with normal concrete in the joint and one RC sub-assemblage with ECC in the joint are designed to gravity loads; neither type has transverse reinforcement in the joint core. Similarly, one RC sub-assemblage with normal concrete in the joint and one with ECC in the joint are designed for seismic provisions, but the latter has no transverse reinforcement in the joint. The test programme thereby allows direct comparison of the structural performance of ECC joints with concrete joints for beam–column sub-assemblages for both gravity and seismic design situations. Results show that the use of ECC joints significantly changes the behaviour of the joint from brittle to ductile. Both ECC specimens exhibit superior damage tolerance, with limited shear distortion and multiple fine cracks in the joints, even though no transverse reinforcement is provided in the joint. Moreover, specimens with ECC joints demonstrate improved bond behaviour in early loading cycles.
La fragmentación del estado en Chile y la gestión de las políticas públicas
Authors: Franco Fabricio
Published: November 2017

Desde mediados de los 80s han tenido lugar un conjunto de reformas en el Estado que han impactado notablemente tanto en su estructura como en la forma en la que se gestionan las políticas públicas en Chile. Esto ha tenido, como una consecuencia no prevista, una creciente fragmentación del Estado y una mayor dificultad en la coordinación y la coherencia de las políticas públicas. Bajo el enfoque de la Nueva Gestión Pública (NGP) estos cambios buscaron una mayor eficacia y eficiencia gubernamental a través de reducir los grandes ministerios por organizaciones públicas más especializadas, autónomas del poder político y focalizadas en desarrollar servicios. Ello ha debilitado la capacidad de coordinación del centro del gobierno para alinear la gestión de diferentes organizaciones y desarrollar políticas públicas más coherentes que limiten la redundancia, los vacíos y las contradicciones entre intervenciones de diferentes sectores y niveles de gobierno.

Evaluating Within‐Plant Variability of Cotton Fiber Length and Maturity
Authors: Ayele Addissu G. , Kelly Brendan R. , Hequet Eric F.
Published: November 2017

Core Ideas

Cultivars showed differences for the within‐plant fiber length and maturity.

Some cultivars exhibited relatively stable within‐plant fiber length and maturity.

Genetic component plays a significant role for the differences among the cultivars.

Previous studies have indicated differences in fiber quality parameters including fiber length and maturity within the canopy of cotton (Gossypium hirsutum L) plants. A 3‐yr study was conducted to investigate the impact of within‐plant variability on fiber length and maturity of upland cotton cultivars widely grown on the High Plains of Texas. Twelve upland cotton cultivars were grown in a randomized complete block design with three field replications, in Lubbock, TX, during the 2012, 2013, and 2014 growing seasons. A box‐picking harvesting method was used to individualize samples so that the within‐plant variability of cotton fiber quality could be studied. Bolls harvested from different positions on the plants were ginned with a tabletop roller gin to minimize fiber damage. The lint from each fruiting position was blended with a supple needles laboratory blender to reduce within‐sample variability while minimizing fiber breakage. Each sample collected from a different fruiting position on the plant was tested on the Advanced Fiber Information System (AFIS) with three replications of 3000 fibers. The results indicated that cultivars such as FM 9170 B2F, NG 4111 RF, PHY 499 WRF, and FM 2484 B2F showed lower within‐plant variability, while DP 1044 B2RF, PHY 367 WRF, and ST 5458 B2F showed relatively high within‐plant variability for AFIS fiber length and fiber maturity. In conclusion, variations in within‐plant fiber length and maturity among upland cotton cultivars could be a potential source of variability for breeding programs aimed at improving fiber quality.

Published: November 2017

Melilotus albus Medik. is a legume species with potential to be used as a forage or conserved fodder in Northwest China. Breeding M. albus as a forage crop is focused on simultaneously improving forage yield and reducing coumarin (Cou) content. The goal of the present study was to estimate genotypic variation for several key agronomic traits and to evaluate the impact of single‐trait selection and Smith–Hazel‐index‐based multitrait selection for herbage dry weight (DW), plant height (PH), stem number (SN), and leaf area (LA). A quantitative genetic analysis was conducted on trait measurements from 25 half‐sib (HS) families evaluated at Yuzhong and Linze, in China. Significant (P < 0.05) genotypic variation among the HS families for all traits was observed. There was also significant (P < 0.05) genotype × environment interaction for all traits except for LA. The predicted genetic gain, based on estimated genotypic variance, for single‐trait selection varied from 2.3 to 30.3% per selection cycle. Pattern analysis of the HS family × multitrait best linear unbiased prediction matrix provided a graphical summary of the association among the traits, as well as the four HS family groups generated from clustering. Some members within Group 1 could be crossed to generate a breeding population to be used in recurrent selection for M. albus cultivar development in Northwest China. The applicability of a Smith–Hazel selection index to increase expression of the traits DW, PH, and SN and reduce LA, indirectly reducing Cou content, was confirmed. This index enabled identification of families for increasing key biomass traits and decreasing Cou production.

Core Ideas

We aimed to advance our mechanistic understanding of desert soil hydrodynamics.

We calibrated and validated a HYDRUS‐1D software version on desert soil data from a weighing lysimeter.

HYDRUS‐1D is an attractive tool for virtual experiments relevant for arid ecosystems.

Although desert soils cover approximately one third of the Earth's land surface, surprisingly little is known about their physical properties and how those properties affect the ecology and hydrology of arid environments. The main goal of this study was to advance our understanding of desert soil hydrodynamics. For this purpose, we developed a process‐based component within HYDRUS‐1D to describe the moisture dynamics of an arid zone soil as a function of water fluxes through the soil surface. A modified van Genuchten model for the dry end of the soil water retention curve was developed to better capture the basic flow processes for very dry conditions. A scaling method was further used to account for variabilities in water retention because of changes in the bulk density vs. depth. The model was calibrated and validated using hourly soil moisture, temperature, and mass data from a 3‐m‐deep weighing lysimeter of the Scaling Environmental Processes in Heterogeneous Arid Soils facility at the Desert Research Institute (Las Vegas, NV). Measurements and simulations during a 1‐yr period agreed better under precipitation (wetting) than under evaporation (drying) conditions. Evaporation was better simulated for wet than for dry soil surface conditions. This was probably caused by vapor‐phase exchange processes with the atmosphere, which were unaccounted for and need to be further explored. Overall, the model provides a promising first step toward developing a more realistic numerical tool to quantify the moisture dynamics of arid ecosystems and their role in climate change, plant growth, erosion, and recharge patterns.
Los pliegues del liderazgo social y comunitario
Authors: Fernández-Fonseca Edgar , Cardona-Sánchez Fernando
Published: November 2017

El presente trabajo busca caracterizar las apuestas investigativas que, entre los años 2004 y 2014, se realizaron en torno al liderazgo social y al liderazgo comunitario por parte de los grupos de investigación clasificados en Colciencias, adscritos a universidades y centros de investigación de la ciudad de Bogotá. La lectura crítica y reflexiva del liderazgo social y comunitario, desde el estado del arte, no solo abre el abanico de posibilidades para conocer más sobre lo ya indagado, sino que, además, potencia la formación de líderes que aprenden de líderes, mediante el reconocimiento de las metodologías emprendidas por estos. En los principales acercamientos al corpus documental que se han dado hasta el momento, se encuentra que estos resultan la otra cara de la misma moneda, lo que dificulta su abordaje conceptual y metodológico. Sin embargo, en este sentido, es posible destacar que mientras en el liderazgo social predomina un agenciamiento institucional marcado por una racionalidad técnica y especializada, en el liderazgo comunitario se destacan acciones orientadas al empoderamiento colectivo bajo una racionalidad pragmática que se asume desde el territorio y la identidad.

BACKGROUND

Recent research indicates that current mHealth apps for bipolar disorders (BDs) show crucial shortcomings. They lack important functionality, are of inconsistent quality, and are insufficiently evidence-based. mHealth apps need to be better adapted to the needs of users. The perspectives of adult service users with BD regarding mHealth apps have not been well investigated.

OBJECTIVE

The objective of this study was to examine the needs and expectations of adults with BD regarding mHealth apps.

METHODS

Two focus group sessions were organized in which patients’ views on self-management and design and functionality of an mHealth app for BD were assessed. During session 1, four focus groups were organized to identify users’ needs regarding support for self-management. Session 2 contained three cocreation focus groups. Through this method, the desired functionality and design were explored.

RESULTS

Participants indicated that they were in need of support in various ways. Not only support in psychoeducation, including daily routine, sleep pattern, maintaining social contacts, maintaining a healthy lifestyle, and avoidance of stimuli, was considered important for them but also gaining insight into their illness was found to be crucial.

CONCLUSIONS

According to the participants, their illness-related information is a key factor in gaining insight into their mood pattern. Participants wanted a functional design that would increase daily use and prevent overstimulation. The results of this study should be taken into account when developing new mHealth apps.

Published: November 2017

BACKGROUND

Self-monitoring and self-management, crucial for optimal glucose control in type 1 diabetes, requires many disease-related decisions per day and imposes a substantial disease burden on people with diabetes. Innovative technologies that integrate relevant measurements may offer solutions that support self-management, decrease disease burden, and benefit diabetes control.

OBJECTIVE

The objective of our study was to evaluate a prototype integrated mobile phone diabetes app in people with type 1 diabetes.

METHODS

In this exploratory study, we developed an app that contained cloud-stored log functions for glucose, carbohydrates (including a library), insulin, planned exercise, and mood, combined with a bolus calculator and communication functions. Adults with diabetes tested the app for 6 weeks. We assessed the feasibility of app use, user experiences, perceived disease burden (through questionnaires), insulin dose and basal to bolus ratio, mean glucose level, hemoglobin A1c, and number of hypoglycemic events.

RESULTS

A total of 19 participants completed the study, resulting in 5782 data entries. The most frequently used feature was logging blood glucose, insulin, and carbohydrates. Mean diabetes-related emotional problems (measured with the Problem Areas in Diabetes scale) scores decreased from 14.4 (SD 10.0) to 12.2 (SD 10.3; P=.04), and glucose control improved, with hemoglobin A1c decreasing from 7.9% (mean 62.3, SD 8 mmol/mol) to 7.6% (mean 59.8, SD 7 mmol/mol; P=.047). The incidence of hypoglycemic events did not change. Participants were generally positive about the app, rating it as “refreshing,” and as providing structure by reinforcing insulin-dosing principles. The app revealed substantial knowledge gaps. Logged data enabled additional detailed analyses.

CONCLUSIONS

An integrated mobile diabetes app has the potential to improve diabetes self-management and provide tailored educational support, which may decrease disease burden and benefit diabetes control.
Geoquímica de lantánidos de los yacimientos de fluorita de los distritos mineros de Taxco y Zacualpan, sur de México: implicaciones sobre el origen y la evolución de los fluidos

We present and evaluate lanthanide contents measured by inductively coupled plasma mass spectrometry (ICP-MS) in fluorite samples from the fluorite deposits in Zacualpan and Taxco mining districts in the south of Mexico. The information is used to distinguish different generations of fluorite, to establish a correlation between mineralization episodes and the wall rock nature, and to identify postdepositional processes.The total lanthanide content of the fluorites are variable, and early- stage fluorite samples are usually enriched in LREE. The concentration of REE in fluorite is low in comparison with the volcanic and metamorphic rocks (∑REE > 100 ppm) and is generally high respect the carbonates (∑REE < 30 ppm). There is host rock influence. The higher REE concentra- tions are in fluorites hosted by volcanic rocks. The fluorite that replaced carbonate is characterized by low REE to very low concentrations. Fluorite samples associated with sulfurs are typically enriched in HREE. Nearly all fluorites show a negative Eu anomaly similar to the REE anomaly observed in the volcanic rock. Only some early stage dark, uranium rich fluorites, from la Azul deposit, have a strong positive Eu anomaly. Direct correlation between color and REE patterns is observed in some samples.In the Zacualpan mining district, only an episode of mineralization has been discriminated, where fluorite presents flat to HREE- enriched chondrite-normalized REE patterns.In the Taxco mining district and particularly in the “Mina la Azul”, multiple hydrothermal events of mineralization have been determined. The first generation of fluorite is formed by replacement of carbonates and is characterized by very low contents of lanthanides, chondrite- normalized REE patterns similar to the limestone, high strontium content and primary textures (e.g. massive fluorite and rhythmites). The second generation of fluorite is related to the entry of new fluid to the system and has higher REE concentrations, chondrite-normalized REE patterns similar to volcanic rocks, low strontium content and secondary textures (i.e. breccias, nodules). Most of the samples show a genetic relationship between fluorite and fluids of magmatic origin.

The Los Barriles basin, located north of the San José del Cabo basin, is part of the Gulf Extensional Province. It is a half graben bounded by the Los Barriles fault system on its western side. Our study confirms that this system is not part of the San José del Cabo fault but an independent structure. The basin fill includes three stratigraphic sequences: SE 1, SE 2, and SE 3. Los Barriles and Trinidad Formations constitute SE 1. The Los Barriles Formation is in contact with the marginal fault and on the eastern margin it rests unconformably upon the plutonic and meta- morphic basement. The unit is composed of conglomerate and sandstone formed in alluvial fans. The marine Trinidad Formation is composed of sandstone and mudstone. Both formations interfinger and constitute fan deltas without foresets, suggesting rapid subsidence along the Los Barriles fault. Calcareous nannofossils in SE 1 point toward an age in the nannofossil zone NN11 (Late Tortonian-Messinian). Thus, faulting and subsidence occurred since the late Miocene, indicating that the Los Barriles fault system is older than the San José del Cabo fault, which had been activated during the Pliocene. The Refugio Formation (SE 2) rests unconformably on the Trinidad Formation; it consists of fossiliferous sandstone and conglomerate originated in a shallow marine coastal set- ting. Laterally, it interfingers with younger portions of the Los Barriles Formation, forming a fan delta setting of probable Pliocene age. The El Chorro Formation unconformably covers all older units and, locally, even Los Barriles fault system. It comprises sandstone and conglomer- ate formed in an alluvial fan depositional environment. These deposits interfinger towards the present coastline with fossiliferous sandstone and conglomerate formed during the last interglacial period, representing SE 3.
