La Prevención del VIH/SIDA en la formación universitaria de los futuros educadores
Authors: Cejudo Cortés Carmen María Aránzazu , Corchuelo Fernández Celia
Published: July 2019

Resumen: En esta investigación se presentan algunos de los resultados sobre los conocimientos de los estudiantes de titulaciones educativas de la Universidad de Huelva sobre el VIH/SIDA, referidos al grado y calidad del conocimiento que tienen sobre esta enfermedad. Gracias a ellos, hemos podido explorar e identificar las repercusiones derivadas de la falta o insuficiencia de información veraz y, proponer acciones educativas en el ámbito universitario, entendido como agente promotor de salud. Mediante un cuestionario aplicado a una muestra de más de seiscientos sujetos, hemos logrado averiguar que, la mitad de ellos obtienen un resultado insuficiente en la prueba de conocimiento, la desinformación de cuestiones capitales -como, las vías de transmisión del VIH- aún persisten. En definitiva, se sugiere la necesidad de elaborar y desarrollar propuestas formativas que mejoren las competencias en esta materia de estos estudiantes, que además serán futuros educadores en ámbitos escolares y sociales.Abstract: This research presents some of the results on University of Huelva Education Degrees students' knowledge towards the HIV/ AIDS, regarding the degree and quality of their knowledge of the disease. Thank to them, we have been able to explore and identify the effects of the absence or lack of veracious information and, consequently, to propose educational actions in the University sphere, which is viewed as a health promotion agent. By means of a questionnaire applied to a sample of over six hundred subjects we managed to discover that, half of them have an insufficient result in the knowledge test, the disinformation of fundamental issues – like ways of transmission of the HIV – remains. In short, our analysis evokes the need to elaborate and develop educational proposals, which would improve the students' competencies in this matter, these students being future education professionals in the school and social spheres.
Formación inicial del maestro y competencia gramatical para su práctica docente
Authors: Jiménez Fernández Rafael , Romero Oliva Manuel Francisco , Heredia Ponce Hugo
Published: July 2019

Resumen: Este trabajo tiene como objetivo comprobar, a partir de un estudio de caso, si los alumnos que acceden a la educación superior (en nuestro caso, futuros maestros de Educación Primaria) demuestran una competencia gramatical elemental que les capacite para afrontar su formación inicial como maestros. A partir de una prueba realizada (cuestionario de dominio gramatical), se ha comprobado que el nivel competencial es bajo y que la variable de estudios de procedencia no es significativa, pues en ambos casos mantienen la falta de dominio gramatical. El estudio se completa con una matriz DAFO que pretende ofrecer líneas de actuación para afrontar esta problemática desde la confluencia de los resultados cuantitativos obtenidos y de las técnicas etnográficas usadas (narrativa biográfica y grupo focal).Abstract: This paper is focused on checking, as a main objective, if the students who get into higher education show a basic grammatical competence that qualifies them to face their initial training as future teachers (in this case, future Primary School teachers). It has been checked that the level of this competence is awfully low and that the study variable is not meaningful, since the lack of grammatical competence remains; those assumptions are based on a grammar skill survey. This study is completed with a SWOT matrix that offers areas of action to solve these problems from the comparison between the quantitative results and the ethnographic techniques used (biographical narrative and focal group)

Credencialismo educativo y desigualdades estructurales persistentes en la era de la modernización en España
Authors: Herrera Cuesta Damián
Published: July 2019

Es frecuente escuchar en los debates políticos que las economías desarrolladas pueden resolver los problemas de las aspiraciones individuales, la eficiencia económica y la justicia social a través de la creación de una economía basada en altas calificaciones y altos salarios. Junto a estas premisas se tiende a otorgar a la universidad un papel de especial protagonismo en el ámbito del desarrollo social y económico. Sin embargo, los bienes credenciales basados en los títulos de educación superior que dan acceso a las mejores posiciones dentro de la estructura de las ocupaciones resultan altamente costosos, tanto si adoptamos el punto de vista cultural como desde la perspectiva económica. En esta nota de investigación presentamos parte de los resultados de un estudio de más de tres años en el que se analiza la importancia de los recursos educativos y económicos disponibles por los estudiantes universitarios de diferentes orígenes socioeconómicos y sus efectos sobre la experiencia universitaria y las diferentes transiciones al mercado laboral, doce meses después de haber finalizado sus estudios.It is common to hear in political debates that developed economies can solve the problems of individual aspirations, economic efficiency and social justice through the creation of an economy based on high qualifications and high salaries. Along with these premises, there is a tendency to grant the University a special role in the field of social and economic development. However, credential goods based on higher education degrees that give access to the best positions within the structure of occupations are highly costly, whether we adopt the cultural point of view or from the economic perspective. In this research note we present part of the results of a study of more than three years in which the importance of the educational and economic resources available to university students of different socioeconomic origins and their effects on the university experience and the different transitions to the labor market, 12 months after completing their studies.

Resumen: Este texto tiene como objetivo estudiar y comparar algunos aspectos de la presencia de Ibn ʿArabī en la obra y en la “mística experimental” de Maria Gabriela Llansol. Nos centraremos en los temas relacionados con el mundus imaginalis (ʿālam al-miṯāl) y en las categorías de “imaginario”,“imaginal” y barzaḫ, que Llansol recibió a través de la lectura de Henry Corbin. En este contexto, nos acercamos de una interpretación de Llansol sobre Fernando Pessoa, según las reflexiones de la escritora sobre el sufismo.

Abstract: This text seeks to study and compare some aspects of the presence of Ibn ʿArabī in the work and in the “experimental mystique” of Maria Gabriela Llansol. We will focus on themes related to the mundus imaginalis (ʿālam al-miṯāl) and on the categories of “imaginary”, “imaginal” and barzaḫ, which Llansol received through reading Henry Corbin. In this context, an interpretation of Llansol is approached about Fernando Pessoa, according to her reflections on Sufism.
AMOR Y NEGROR EN LLANSOL COMO COMPROMISO CON LA OTREDAD
Authors: Fernández Navas David
Published: July 2019

Resumen: El texto pretende un acercamiento al carácter amoroso de la escritura de Maria Gabriela Llansol. Explica cómo ésta, igual que la de María Zambrano, lleva la defensa amorosa del devenir de Nietzsche un paso más allá, en tanto nace de un interés por la otredad en sí misma y no de una voluntad de autoafirmación. La ruptura de las nociones convencionales de tiempo, espacio e identidad será una de las vías que utiliza. En ello puede apreciarse cierta similitud con Muḥyī al-Dīn Ibn ʿArabī, de quien aprendió la necesidad de buscar un tiempo propio para el alma, diferente del cuantitativo y cuya doctrina del amor y de la santidad exige un genuino interés en la otredad en tanto otredad.

Abstract: The text is an attempt to approach the loving character of the writing of Maria Gabriela Llansol. It explains how her works, similarly to those of María Zambrano, go further than Nietzschein the affirmation of the becoming: as long as there is not will of self-affirmation, but an authentic interest in alterity. One of the paths she explores is to break the conventional notions of time, space and identity. It is possible to appreciate two coincidences with Muḥyī al-Dīn Ibn ʿArabī. First, Llansol learned from him the need of an own time for the soul, different from quantitative time. Second, Ibn ʿArabī’s doctrine of love and sainthood also implies a genuine interest in otherness as otherness.

Resumen: Se pretende con este texto propiciar un acercamiento entre las escrituras, tan diferentes en su forma, de María Zambrano y Maria Gabriela Llansol, buscando coincidencias o analogías en el marco de una reflexión sobre la poesía y la palabra creadora, que tiene en cuenta a otros poetas y escritores y que no quiere apartarse tampoco del sufismo de Ibn ʿArabī como fuente de inspiración e interpretación.Abstract: The aim of this text is to promote an approach between the writings of María Zambrano and Maria Gabriela Llansol, looking for coincidences or analogies within the framework of a reflection on poetry and the creative word, which takes into account others poets and writers and who does not want to separate either from Ibn ʿArabī ‘s Sufism as a source of inspiration and interpretation.
NOTAS SOBRE O AMOR EM MARIA GABRIELA LLANSOL E EM MARCIA MILHAZES
Authors: Rosa Luiza
Published: July 2019

Resumo: A vinculação entre o assombro provocado pelas obras de Marcia Milhazes, e o assombro provocado pela escrita de Maria Gabriela Llansol, dá forma a um enigma que não tem que ver apenas com acaso de terem sido vivenciados por mim, em dado momento da minha vida. Com efeito, considero que este assombro, tão inerente à dimensão do íntimo nas duas autoras, e pelo qual se manifesta ainda o referido caráter enigmático das duas obras, é provocado em ambas por aquilo que podemos nomear de espelhamento entre a paisagem íntima e a paisagem ao redor, sendo o espelhamento ruidoso, contíguo com paisagens solares cariocas – Brasil – em Milhazes, e o espelhamento silencioso em contiguidade com paisagens belgas, em Llansol.Sem pretenção de desenvolver aqui uma análise comparativa entre as duas autoras, quero apenas sugerir a maneira como este espelhamento se dá, a meu ver, em ambas, nomeadamente no romance-diário Finita da escritora portuguesa Llansol, em que ecoa a mística do amor de Ibn ʿArabī, e no espetáculo de dança Guarde-me, de Marcia Milhazes, no qual a diretora brasileira diz escrever cartas de amor.

Introduction: Depression in older adults is a major health problem, and it is considered the most common psychiatric disorder among this population in developing countries. It is associated with suffering and increased prevalence and poor evolution of health problems. The aim of the present study was to determine the prevalence of depression and related factors in people over the age of 75 years in the city of Castellón de la Plana, Spain.Methodology: This was an observational, cross-sectional, and analytical study in which a questionnaire was administered to a sample of 400 community-dwelling older adults over the age of 75 and who were selected using purposive sampling in 2015.Results: the overall prevalence of depression symptoms was 30.5%, a percentage higher among women (40.1%). Older adults living alone presented more symptoms of depression, 26.6% compared with 16.1% (p = 0.011). Good self-perceived health was related to fewer depression symptoms. Non-frail individuals presented lower rates of depression symptoms (12.1%) than frail (30.8%), and pre-frail individuals (57%) p<0.05. Negative aspects in social relationships showed a lower mean score (0.003) in individuals without depression symptoms (p = 0.006).Conclusions: There is a link between the presence of depression symptoms and gender, self-perceived health, living condition, and frailty.
Prácticas artísticas en la época del dataceno. Data Biography: rastros digitales para la exploración biográfica de la identidad personal
Authors: Díaz Diego , Boj Clara
Published: July 2019

Cada vez más detalles de nuestra vida son registrados y almacenados para formar parte de lo que ha venido a llamarse big data. Nuestra vida, en todos sus aspectos, deja un rastro digital que se actualiza continuamente en función de actividades, tanto de la vida física como de la vida digital, que alimentan bases de datos en las que se refleja tanto el último libro que hemos comprado como las visitas médicas que hemos realizado. Muchos de esos datos son abiertos y accesibles, otros son propiedad de empresas privadas que comercializan con ellos.

En esta publicación inicialmente introducimos y justificamos la conveniencia de utilizar el termino dataceno, entendido como una metáfora para comprender la sociedad actual como una sociedad mediada por los datos digitales. Posteriormente, realizamos una clasificación de las practicas artísticas contemporáneas con distintas aproximaciones al uso y análisis de datos complejos: desde la creación de atractivas visualizaciones bajo el propósito de acceder a la información escondida en los grandes volúmenes de datos, hasta aproximaciones más conceptuales que nos acercan a un planteamiento crítico sobre el volumen, recolección, uso y comercialización de los mismos.

En la última parte de esta publicación, nos centramos en analizar las creaciones artísticas basadas en rastros digitales y en el concepto de biografía narrativa en la era del dataceno. Por último, analizamos nuestra obra Data Biography, una propuesta de diseño especulativo que cuestiona la escritura biográfica, utilizando los datos recogidos de nuestro rastro digital en redes sociales, WhatsApp, correos electrónicos, sitios web visitados, búsquedas en Google, imágenes, ubicación de gps, etc.
¿Qué prueba una imagen?
Authors: León-Mendoza Raúl
Published: July 2019

Este artículo es un ensayo crítico sobre la imagen-dato, que pretende desvelar las características que la elevan, de entre todos los modos de representación, a su actual estatus de prueba. A partir de dos estudios de caso, donde son usadas imágenes de videovigilancia, reflexionamos sobre la inflación que sufre la imagen-dato en su circulación, desde su papel original como dispositivo propio del ámbito de la seguridad hasta su actual papel como recurso al servicio del entretenimiento de masas. Para explicar las mutaciones que sufre esta categoría de representación (imagen-dato), y su conversión en una prueba en los ámbitos jurídicos y sociales, nos hemos apoyado en la genealogía de la imagen disciplinaria trazada por Tagg, en el concepto de estética forense de Weizman y de imagen-spam de Steyerl.
Hemos hallado en el análisis de los casos estudiados determinadas características propias de la imagen-vigilancia que contribuyen a segregarlas cualitativamente del resto de imágenes contemporáneas. Su aspecto difuso, su relación contingente con el suceso que captan, la aparente ausencia de subjetividad que presentan, la constituyen como una categoría de imagen que mantiene la relación más sólida posible con su referente, siendo prácticamente la misma cosa. La imagen-dato, con su plusvalía semiótica, provoca una confusión absoluta entre representación y realidad. Sin embargo, desde nuestro punto de vista, las imágenes no prueban nada. Son simplemente un dispositivo de predicción del pasado, que sirve fundamentalmente como superficie especular de proyección del deseo de ver lo que se quiere ver.
Como especialistas en la producción de imágenes, tenemos la obligación de poner en crisis estas lógicas de la representación e intentar al menos desvelar los dispositivos de producción de verdad en el régimen escópico de la posverdad.
Fusion into One: Exploring the Complementarity of Shitao’s Waterfall on Mount Lu and Its Inscribed Poem
Authors: Liu Zao
Published: July 2019

Shitao’s famous poem-painting Waterfall on Mount Lu has generated a great interest in the field of Chinese paintings. However, the purpose of the work remains a topic of discussion among scholars. From the standpoint of complementarity of poetry and painting, this paper discusses the work through a close examination of the painting and its inscribed poem. The interartistic features of the painting and the poem are interpreted in terms of their themes, structures, and imagery. The Chinese aesthetic concept of artistic mood (yijing) is employed to illustrate the connection among these elements. This paper demonstrates that the holistic approach to the poem-painting helps illuminate its Daoist theme of unity of man and nature. This paper also highlights a structural contrast between the secular world and the eternal world expressed in the peom-painting.
Intrageneric differences in the effects of acute temperature exposure on competitive behaviour of damselfishes
Authors: Warren Donald T. , McCormick Mark I.
Published: July 2019

Projected increases in global temperatures brought on by climate change threaten to disrupt many biological and ecological processes. Tropical ectotherms, like many fishes, can be particularly susceptible to temperature change as they occupy environments with narrow thermal fluctuations. While climate change models predict temperatures to increase over decades, thermal fluctuations are already experienced on a seasonal scale, which may affect the ability to capture and defend resources across a thermal gradient. For coral reef fish, losers of competitive interactions are often more vulnerable to predation, and this pressure is strongest just after settlement. Competitive interactions may determine future success for coral reef fishes, and understanding how temperature experienced during settlement can influence such interactions will give insight to community dynamics in a future warmer world. We tested the effect of increased temperatures on intraspecific competitive interactions of two sympatric species of reef damselfish, the blue damselfish Pomacentrus nagasakiensis, and the whitetail damselfish Pomacentrus chrysurus. Juvenile fishes were exposed to one of four temperature treatments, ranging from 26–32 °C, for seven days then placed into competitive arenas where aggressive interactions were recorded between sized matched individuals within each species. While there was no apparent effect of temperature treatment on aggressive behaviour for P. chrysurus, we observed up to a four-fold increase in aggression scores for P. nagasakiensis with increasing temperature. Results suggest that temperature experienced as juveniles can impact aggressive behaviour; however, species-specific thermal tolerances led to behavioural affects that differ among closely related species. Differential thermal tolerance among species may cause restructuring of the interaction network that underlies the structure of reef assemblages.

Authors: Sahu Pravin Kumar , Chakradhari Suryakant , Patel Khageshwar Singh , Martín-Gil Jesús , Towett Erick K. , Martín-Ramos Pablo
Published: July 2019

Aims: Species of the family Lamiaceae possess a rich tradition of use for flavoring and medicinal purposes. This paper focusses on the nutritional and thermal characteristics of the seeds from eight species belonging to this family: Gmelina arborea Roxb. ex Sm., Hyptis suaveolens (L.) Poit., Leonotis nepetifolia (L.) R.Br., Ocimum americanum L., Ocimum sanctum L. (Rama Tulsi), Ocimum tenuiflorum L. (Krishna Tulsi), Origanum vulgare L. and Tectona grandis L.f.

Methodology: The oil, starch, total polyphenol, flavonoid and mineral contents for aforementioned seeds were determined. Fourier-transform infrared (FTIR) spectroscopy was used to assess the phytoconstituents. Thermogravimetric/derivative thermogravimetric analyses (TG/DTG) and differential scanning calorimetry (DSC) analyses were performed to analyze the decomposition patterns.

Results: The concentrations of oil, starch, total polyphenol, flavonoids and minerals for the seeds from the eight plants under study ranged from 11.8 to 50.4%, from 0.22 to 1.84%, from 295 to 5842 mg/kg, from 1660 to 12680 mg/kg and from 11756 to 33927 mg/kg, respectively. Unsaturated oils, polyphenols and lignin were recognized by vibrational spectroscopy. The sequence of thermal effects in the seed pyrolysis process above 100°C have been put in relation to seed protein crystallization (endotherm at 200°C), oxidation reactions and degradation of hemicellulose and other fiber components (at around 300°C), and decomposition of polyunsaturated (at 357°C) and mono-unsaturated (at 391°C) triglycerides.

Conclusion: Lamiaceae seeds are potential food alternatives to cereals.
Haematological Parameters Associated with Malaria and Its Controls
Authors: Francis Ussher Abeku , Daniel Amiteye
Published: July 2019

Aims: This research aimed to evaluate the haematological parameters associated with malaria and its controls.

Materials and Methods: A convenient cross-sectional technique was used for the study for which the sample size was determined by using the formula; n= Z² (P) (1-P) / (A) ². The haematological profile was performed using the Sysmex 2000i automated blood cell counter machine.

Results and Discussion: The erythrocyte profiles (RBC, HB, HCT, RDW-SD and RDW-CV) are highly affected by malaria, whereas MCH, MCHC, and MCV did not show significant variations between the positive malaria cases and negative malaria cases. Means of haemoglobin concentrations, RBC count and HCT values for cases with positive malaria were significantly lower than negative malaria cases and controls for all the age groups and sexes.

Conclusion: The study showed that there were haematological profiles between the positive and negative malaria cases and this can be used in conjunction with clinical and microscopic parameters to heighten the suspicion of malaria as well as prompt initiation of therapy for diagnosing malaria.

The objective of this work was to study the influence of three management systems on the physical attributes and productivity of irrigated wheat, cultivar BRS-254, in the city of Tangara da Serra, MT.  The soil physical attributes were: weighted mean diameter (DMP) and geometric mean diameter (DMG).  The experimental design was in randomized blocks. The treatments for weighted average diameter (WMD) and geometric mean diameter (DMG) were arranged in a subdivided plot scheme, with eight replications. The tilting preparations obtained the highest DMPs compared to SD both in the 0-10 cm layer and in the 10-20 cm layer, a result possibly related to the incorporation of residues during the soil preparation associated with higher mucilage production promoted by higher activity of the root system of the crop, which found better soil physical conditions for its development. The PC presented a reduction in DMP when comparing the value in the 0-10 cm layer with the value in the 10-20 cm layer. The significant effect of soil preparation on DMG can also be a result of the incorporation of residues during the preparation, associated to the effect of higher root volume promoted by the higher root growth of the crop in these preparations, which, in turn, guarantee greater production of mucilages promoting greater soil aggregation and higher DMG. The use of the disk grid in the PC and PM interferes with the soil attributes. Soil inversion provided higher WMD and DMG.

Published: July 2019

Objectives: This study aimed to determine the effect of group counseling on the identity crisis of middle-aged women referred to outskirt health centers of Urmia, Iran in 2018.

Methods: This randomized, pre-test and post-test control study was conducted on 90 middle-aged women registered in Iranian Registry of Clinical Trials (IRCT). A researcher visited selected health centers of Urmia randomly divided into three groups according to their social, economic and cultural status (26 health centers at high level, 19 health centers at average level, and 20 health centers at low level). The subjects were those who referred to the family health unit for receiving health care. The demographic characteristics questionnaire (such as age, marital status, number of children, educational level, body mass index, employment status and economic situation, which was designed by the researcher), and middle aged Identity Crisis Questionnaire (ICQ) including aimlessness, futility, hopelessness, lack of self-confidence, worthlessness, dissatisfaction with life, anxiety, sadness, aggression and anger subscales. The intervention (counseling group) was conducted for six weeks held weekly and each session for 60-90 minutes. Independent t-test, Chi-square test and Fisher's exact test were performed and analyzed through SPSS software. A P value less than of 0.05 was considered significant.

Results: Mean age of women in the intervention group (50. 93 ± 5.38 years) and in the control group (50.55 ± 6.23 years) was 50 years. Also, in the intervention and control groups, the mean number of children was 2.43 ± 1.47 and 2.44 ± 1.49, respectively. In this study, the two groups were homogeneous regarding BMI, education level, husband's education level, economic status, marital status, occupation and dwelling situation (P> 0.05). Mean score of identity crisis and its ten dimensions before and after the intervention in the two groups were significantly different (P<0.001). There was no significant difference in any of the dimensions of identity crisis in the control group (P>0.05).

Conclusion: According to the results, the use of group counseling intervention has been able to improve the identity crisis of middle-aged women in the most dimensions of identity crisis including aimlessness, futility, hopelessness, lack of self-confidence, worthless, dissatisfaction with life and anxiety.
Tissue‐ and cell‐specific expression of a splice variant in the II‐III cytoplasmic loop of Cacna1b
Authors: Bunda Alexandra , LaCarubba Brianna , Akiki Marie , Andrade Arturo
Published: July 2019

Presynaptic CaV2.2 (N‐type) channels are fundamental for transmitter release across the nervous system. The gene encoding CaV2.2 channels, Cacna1b, contains alternatively spliced exons that result in functionally distinct splice variants (e18a, e24a, e31a, and 37a/37b). Alternative splicing of the cassette exon 18a generates two mRNA transcripts (+e18a‐Cacna1b and ∆e18a‐Cacna1b). In this study, using novel mouse genetic models and in situ hybridization (BaseScope™), we confirmed that +e18a‐Cacna1b splice variants are expressed in monoaminergic regions of the midbrain. We expanded these studies and identified +e18a‐Cacna1b mRNA in deep cerebellar cells and spinal cord motor neurons. Furthermore, we determined that +e18a‐Cacna1b is enriched in cholecystokinin‐expressing interneurons. Our results provide key information to understand cell‐specific functions of CaV2.2 channels.

Published: July 2019

Materials capable of varying their acoustic impedances to match those of air, water, and solid materials over broadband frequencies will enable new applications in fields as diverse as medical imaging, underwater sonar and communication, and marine biology. However, such tunability has not been achieved with conventional acoustic materials including metals, polymers, ceramics and woods. Here, the invention of metagel, a class of designed hydrogel composites with unprecedented tunable acoustic properties over broadband frequencies, is reported. The metagel consists of patterned channels in a tough hydrogel matrix, where air, water, or liquid metal can be purged through the channels to tune the metagel's acoustic transmission over air–water–solid ranges and broadband frequencies on demand. It is shown that the acoustic properties of the metagel can be tuned by varying the volume ratio of the channels, properties, different filler materials with combined experiments, theory, and simulations. The metagel enables novel functions such as adjustable imaging regions of ultrasound, demonstrating tangible applications in underwater acoustics and medical imaging.
Tunable, Cost‐Effective, and Scalable Structural Colors for Sensing and Consumer Products

Published: July 2019

The cost‐effective colorimetric detection of chemicals can be a potential substitute for expensive spectrometers. Here, a structural color sensor is presented that can distinguish seven different organic solvents through a timed sharp color change. The color sensor is based on interference effects in a metal–insulator–metal Fabry–Perot (FP) cavity with polydimethylsiloxane (PDMS) serving as the dielectric layer. By tuning the cross‐linker to monomer ratio of PDMS and employing a porous nickel (Ni) top layer, the PDMS films experience shrinkage that results in substantial color changes. The time‐dependent color change can be used to indicate the type of solvent that the sensor was exposed to. When the sensor is immersed in a solvent, the PDMS diffuses through the porous Ni film at different rates depending on the solvent, resulting in a shrinkage of the PDMS and resonance shift of the FP cavity. Materials used in this single‐use sensor are cost effective (≈0.28 USD m−2), and the fabrication process requires no lithography and is scalable. Moreover, the FP configuration produces vibrant colors that cover ≈50% of the standard Red Green Blue (sRGB) color space and is suited for decorative purposes and consumer products as well.

The reactions of tetrahedral molybdenum complexes bearing unsubstituted heterodiatomic Group 15 elements, [Cp2Mo2(CO)4(μ,η2:η2‐PE)] (Cp=C5H5; E=As (1), Sb (2)), with CuI halides afforded seven unprecedented neutral supramolecular assemblies. Depending on the Mo2PE units and the CuI halide, the oligomers [⟨{Cp2Mo2(CO)4}{μ4,η2:η2:η2:η1‐PE}⟩4⟨{CuX}{Cu(μ‐X)}⟩2] (E=As (X=Cl (3), Br (4)); E=Sb (X=Cl (6), Br (7))) or the 1D coordination polymers [{Cp2Mo2(CO)4}{μ4,η2:η2:η1:η1‐PAs}{Cu(μ‐I)}]n (5) and [{Cp2Mo2(CO)4}{μ4,η2:η2:η2:η1‐PSb}2{Cu(μ‐X)}3]n (X=I (8), Br (9)) are accessible. These solid‐state aggregates are the first and only examples featuring the organometallic heterodiatomic Mo2PE complexes 1 and 2 as linking moieties. DFT calculations demonstrate that complexes 1 and 2 present a unique class of mixed‐donor ligands coordinating to CuI centers via the P lone pair and the P−E σ‐bond, revealing an unprecedented coordination mode.
Cationic organofluorosilicone as deepening agent in the application of dyed polyester fabric
Authors: Yu Chengbing , Lu Yilin , Wu Fangfang
Published: July 2019

Polyester fabrics are usually difficult in dyeing deeply due to their dense structure and high surface refractive index, and deepening finishing is an effective method to obtain dark polyester fabrics. In this article, octamethyl cyclotetrasiloxane (D4), 1,3,5‐tris(3,3,3‐trifluoropropyl)‐methylcyclotrisiloxane (D3F), and silane coupling agent KH‐902 were used as main monomers to synthesize organic fluorosilicone, and further to prepare cationic organofluorosilicone (COFS) and COFS darkening agent. FTIR and 1H‐NMR were used to characterize the structure of synthetic products. The finishing experiments confirmed that COFS darkening agent had good shade darkening on dyed polyester fabrics with small color change. The optimum conditions of deepening finishing were COFS darkening agent concentration of 20%, the pick‐up of 85%, and the curing temperature of 180 °C. After finishing, the dyed fabric had no lowering effect on color fastness, all at grade 4 or above. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48208.

The antioxidative effects of 30 xanthone derivatives (XDs) (XD‐n, n = 1–30) in HepG2 cells were evaluated by the cellular antioxidant activity assay. Results showed that all XDs were antioxidants and 1,3,5,8‐tetrahydroxy‐9H‐xanthen‐9‐one (XD‐2) was the most active antioxidant. The all‐oxygenated substituted xanthones extended the lifespan of wild‐type N2 nematodes under normal culture conditions and XD‐2 was the best one. XD‐2 eliminated excessive intracellular reactive oxygen species and enhanced the expression levels and activities of the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase. XD‐2 inhibited the H2O2‐increased phosphorylation levels of c‐JUN N‐terminal kinase, extracellular signal‐regulated kinase, and p38 in HepG2 cells. In vivo, XD‐2 also extended the lifespan of wild‐type N2 nematodes under oxidative stress induced by paraquat, but failed in extending the lifespan of CF1038 (daf‐16 deletion) and AY102 (pmk‐1 deletion) mutant nematodes. It was revealed by real‐time polymerase chain reaction that the genes daf‐16, sir‐2.1, akt‐1, and age‐1 were all inhibited by paraquat stimuli, while XD‐2 reversed these inhibitions; in contrast, paraquat stimuli upregulated both the skn‐1 and pmk‐1 genes. However, treatment by XD‐2 further increased the levels of both genes. These pieces of evidence implied that XD‐2 promotes longevity through endogenous signaling pathways rather than through the antioxidative activity alone. Taken all together, it may be concluded that XD‐2 is a promising antiageing agent.
Use of “super‐glue” to seal a perforation during chronic total occlusion coronary intervention and the potential to “unglue” it

Coronary perforation remains a dreaded complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We present a case of successful CTO recanalization complicated by a perforation treated by n‐butyl‐cyanoacrylate (medical “super‐glue”). We also present an in vitro experiment showing that a glue plug in a plastic tube can acutely be passed by a low tip load guide wire and undergo balloon angioplasty recreating a lumen. These results suggest that n‐butyl‐cyanoacrylate glue may be an alternative for treating perforation during CTO PCI with the possibility of recanalizing the vessel through the glue plug at a later time.

Published: July 2019

A group of sulfonium salts equipped with a polyhydroxylated side‐chain structure have been isolated and identified as potent α‐glycosidase inhibitors. Consequently, they have become an attractive target in diverse research disciplines, including organic synthesis, drug discovery, and chemical biology. To this end, the development of practical and effective synthetic strategies, especially for more bioactive de‐O‐sulfonated sulfonium salts, is a significant research area in organic synthesis. An ideal synthetic methodology should provide easily accessible intermediates with high chemical stability for the key coupling reaction to diastereoselectively construct the sulfonium cation center. This minireview summarizes recently developed strategies applied in the construction of natural de‐O‐sulfonated sulfonium sugars: 1) acid‐catalyzed de‐O‐sulfonation of sulfonium sulfate inner salts, 2) a coupling reaction between side‐chain fragments containing leaving groups and a thiosugar, 3) a coupling reaction between side‐chain fragments containing epoxide structures and a thiosugar, and 4) a two‐step sequential SN2 nucleophilic substitution between side‐chain fragments containing thiol groups and a diiodide derivative.

Effective environmental assessment and management requires quantifiable biodiversity targets. Biodiversity benchmarks define these targets by focusing on specific biodiversity metrics, such as species richness. However, setting fixed targets can be challenging because many biodiversity metrics are highly variable, both spatially and temporally. We present a multivariate, hierarchical Bayesian method to estimate biodiversity benchmarks based on the species richness and cover of native terrestrial vegetation growth forms. This approach uses existing data to quantify the empirical distributions of species richness and cover within growth forms, and we use the upper quantiles of these distributions to estimate contemporary, “best‐on‐offer” biodiversity benchmarks. Importantly, we allow benchmarks to differ among vegetation types, regions, and seasons, and with changes in recent rainfall. We apply our method to data collected over 30 yr at ~35,000 floristic plots in southeastern Australia. Our estimated benchmarks were broadly consistent with existing expert‐elicited benchmarks, available for a small subset of vegetation types. However, in comparison with expert‐elicited benchmarks, our data‐driven approach is transparent, repeatable, and updatable; accommodates important spatial and temporal variation; aligns modeled benchmarks directly with field data and the concept of best‐on‐offer benchmarks; and, where many benchmarks are required, is likely to be more efficient. Our approach is general and could be used broadly to estimate biodiversity targets from existing data in highly variable environments, which is especially relevant given rapid changes in global environmental conditions.
Sexually differential tolerance to water deficiency of Salix paraplesia—A female‐biased alpine willow

Salicaceae plants are dioecious woody plants. Previous studies have shown that male individuals are more tolerant to water deficiency than females for male‐biased poplars. However, Salix paraplesia is a female‐biased species in nature. It is still unknown whether female willows are more tolerant to drought stress than males. To better understand the sexually different tolerance to water deficiency in willows, a greenhouse experiment combined with a field investigation was conducted, and physiological traits were tested in male and female S. paraplesia under a drought‐stressed condition (50% of soil water capacity). Our field investigation showed that S. paraplesia was a species with female‐biased sex ratio along altitude gradients (2,400 m, 2,600 m and 2,800 m) in their natural habitats. Our results showed that the height growth, biomass accumulation, total chlorophyll pigment content (TChl), and the net photosynthetic rate were higher in female willows than in males at the low and middle altitudes (2,400 m and 2,600 m) rather than at a high altitude (2,800 m) under well‐watered conditions. Under drought‐stressed conditions, the growth, biomass, and photosynthesis were greatly inhibited in both sexes, while females showed higher biomass and TChl content and suffered less negative effects than did males. Particularly, females that originated from a high altitude showed lower leaf relative electrolyte leakage, malondialdehyde content, and less disorder of chloroplast ultrastructures but a higher peroxidase activity (POD) than that of males. Therefore, S. paraplesia females exhibited a better drought tolerance and self‐protective ability than males from high altitude. There is a reason to speculate that the population structure of S. paraplesia at a high altitude would be likely to further female biases with the increased drought intensity in the alpine regions.

Despite the importance of arbuscular mycorrhizal fungi (AMF) within deciduous forest ecosystems, we know little about how natural AMF communities are structured in the root zone of the endangered elm speciesUlmus chenmoui. In this study, threeU. chenmouisampling sites, differing with respect to plant health, age, and growth status, were selected in Anhui Province, China. AMF biodiversity in the root zones of individualU. chenmouitrees was investigated using high‐throughput sequencing. In total, 61 AMF operational taxonomic units were detected. Five genera, namelyGlomus(62.82%),Paraglomus(17.82%),Rhizophagus(4.29%),Septoglomus(4.06%) andFunneliformis(2.35%), and 29 species of AMF were identified. Correlation analysis indicated that available soil phosphorus and potassium concentrations were the main edaphic factors influencing AMF community structure. There was a difference in AMF species richness among the threeU. chenmouistands. Our study showed that soil nutrient concentrations and plant health, age, and growth status can exert a selective effect on the composition of the AMF population in the soil in the root zones ofU. chenmouitrees.
