Repensar la politización del arte. Hacia una lectura de la destitución sensorial en el cine de Paz Encina y Raúl Ruiz
Authors: Palomino Alexis , Sánchez Matías
Published: October 2024

A la luz del trabajo cinematográfico de Paz Encina y Raúl Ruiz, este artículo problematiza algunas lecturas del concepto benjaminiano de politización del arte, prestando especial atención a la capacidad del cine para producir una destitución sensorial. El problema de la politización del arte se piensa desde el rol del arte en la política: como un dispositivo que resiste la narcosis sensorial impuesta por políticas posdictatoriales estetizantes del Cono Sur. A través de un análisis comparado de lectores contemporáneos de la obra de Walter Benjamin y de una reconsideración de la influencia de Marx en este contexto, el artículo destaca la relevancia de una concepción «politizada del arte», en conexión con una comprensión de las imágenes que modifica nuestra experiencia perceptivo-sensorial como elemento clave de nuestra noción histórica. 320-342
Estéticas de lo insensible: el orden in-mundo de las relaciones
Authors: Souyris Oportot Lorena
Published: October 2024

A partir de un estudio teórico, el presente artículo busca examinar las dinámicas estético-afectivas que se manifiestan en campos de experiencias y de (con)tactos los cuales han ordenado prácticas in-mundas. Tal examen, asume una reflexión que apunta a problematizar la insensibilidad, no sólo en cuanto antinomia de la sensibilidad, sino igualmente, como una analítica de lo insensible que ha regulado un sentimiento de indiferencia frente al otro organizando una forma de habitar el mundo actual que se cumpliría en la particularidad individualizada y en la contingencia, revelando así una disponibilidad para lo insensible. La tesis que se intenta sostener es que esta disponibilidad se originaría desde una tópica psíquica la cual legitimaría la idea lacaniana de que el sujeto surge como efecto de una diferencia significante, a saber, de una grieta constitutiva la cual conlleva una relación excéntrica con el Yo y que se manifestaría en una segregación interna exteriorizada en la antinomia sensibilidad/insensibilidad; pero también, reflejada en otra antinomia hospitalidad/inhospitalidad en la constitución de la experiencia de cómo hacemos mundo.
Escuchar lo inaudito: filosofía y música en los inicios de la teoría crítica
Authors: Hervás Muñoz Marina
Published: October 2024

Este trabajo tiene como objetivo ofrecer una visión general sobre la música como objeto de reflexión filosófica en el marco del surgimiento de la teoría crítica. Para ello, se presenta un panorama conciso sobre la consideración de la música en los debates públicos y políticos de principios del siglo XX, con especial atención a las revistas y discusiones de la época. Posteriormente, se analizan los aspectos más relevantes de la relación entre filosofía y música en las obras de tres pensadores que, en torno al mismo período, comenzaron a desarrollar un proyecto filosófico en torno a la música: Theodor W. Adorno, Ernst Bloch y Günther Anders (cuya obra musical, publicada recientemente, aún no ha tenido suficiente atención académica). En particular, se explora la tensión entre el lenguaje y la música, enfocándose en los problemas de la expresión y la construcción, así como en la caracterización de la experiencia musical. Finalmente, se examina críticamente el carácter utópico de la música.
En el corazón de lo imposible: Walter Benjamin, Marcel Proust y La Recherche
Authors: Della Torre Bruna
Published: October 2024

Este artículo explora la centralidad de la novela de Marcel Proust À la Recherche du temps perdu en la crítica literaria de Walter Benjamin. Celebrando el centenario del Instituto de Investigación Social, reevalúa cómo Benjamin se relacionó con la obra de Proust y destaca la importancia del arte y la literatura para una Teoría Crítica radical. Para Benjamin, Proust es un escritor subversivo que trasciende la novela como género y subvierte la relación entre la novela y el tiempo a través del recuerdo. La Recherche también es una fuerza poderosa para la teoría crítica de Benjamin. Por lo tanto, el artículo aborda además la presencia de temas proustianos en sus reflexiones sobre la historia y la revolución.
Alegoría y porosidad en Walter Benjamin. Del Trauerspiel al ensayo sobre Nápoles
Authors: Escuela Cruz Chaxiraxi
Published: October 2024

El 19 de agosto de 1925 Walter Benjamin y Asja Lacis publican en el Frankfurter Zeitung «Nápoles», un ensayo sobre la ciudad italiana en el que analizan las costumbres y prácticas culturales de la zona a partir de un peculiar método de superposición de imágenes. Si bien resulta habitual estudiar Calle de dirección única o Infancia en Berlín como textos tempranos en los que Benjamin se aproxima a la fisionomía como forma de expresión, este trabajo pretende llamar la atención sobre la primera de las Denkbilder sobre ciudades que Benjamin había elaborado en los años veinte y a la que seguirán «Moscú», «Marsella» o «San Gimignano». El objetivo es mostrar de qué manera estos retratos de ciudades no solo permiten al autor dar cuenta de los cambios que experimentaron las urbes europeas a partir del siglo XIX, sino también poner en marcha una teoría de la representación que parte del estudio de los recursos alegóricos en el Trauerspiel sobre los que trabajaba en esa época. Con ello, el ensayo sobre Nápoles será presentado como el primero de los esfuerzos llevados a cabo por Benjamin para conducir la investigación sobre la dramática barroca a problemas de la cultura contemporánea.
El concepto de sociedad y el intercambio de mercancías en Adorno
Authors: Bonnet Alberto
Published: October 2024

Este artículo presenta sintéticamente la manera en la que Adorno fundamenta su concepto de sociedad en una socialización mediada por el intercambio de mercancías (en el primer apartado) y propone (en el segundo apartado) tres aspectos de su argumentación que merecen discutirse y/o desarrollarse. Estos tres aspectos son: (1) el escaso desarrollo de su noción clave de “principio del intercambio”; (2) la influencia de la concepción del “capitalismo de Estado” en su pensamiento, que resulta incompatible con su concepción de una sociedad socializada a través del intercambio; y (3) la ausencia de un desarrollo de la forma jurídica de ese intercambio, complementaria de su forma económica. La fuente principal del artículo son sus escritos, conferencias y seminarios sociológicos, filosófico-sociológicos o filosóficos escritos y dictados en las décadas de 1950-60. El concepto de sociedad de este último Adorno es, en nuestra opinión, el más elaborado con el que cuenta la teoría crítica de la sociedad para orientar sus investigaciones sobre la sociedad capitalista. La intención de este artículo es, en consecuencia, contribuir a una apropiación crítica de dicho concepto identificando aquellos problemas e indicando caminos posibles para su solución. 129-151
Sobre el concepto de no-identidad en la Dialéctica Negativa de Adorno
Authors: Fleck Amaro
Published: October 2024

El concepto de no-identidad no es solo uno de los conceptos más importantes de la obra Dialéctica Negativa de Theodor W. Adorno, sino también uno de los más enigmáticos. En buena medida, este carácter enigmático surge de un uso ambiguo o fluctuante del término en la obra. El pensador frankfurtiano utiliza el concepto tanto para referirse a la no-identidad entre el concepto y el objeto conceptualizado como crítica social, refiriéndose así al hecho de que los conceptos son apariencias socialmente necesarias de una situación ilegítima; como para indicar la no-identidad entre concepto y objeto conceptualizado como crítica del conocimiento, mostrando así que el objeto excede lo que su concepto puede abarcar, mientras que también el concepto excede su objeto. En el presente artículo defiendo la tesis de que este uso fluctuante del término se debe a una interpretación problemática de la teoría de la plusvalía de Marx, la cual permite a Adorno vincular la crítica de la ideología (no-identidad entre concepto y conceptualizado como crítica social) con la crítica del fetichismo (no-identidad entre concepto y conceptualizado como crítica del conocimiento). Esta interpretación es crucial para justificar la tesis del protoparentesco entre el principio de intercambio y el principio de identidad, trayendo consecuencias para el proyecto adorniano de unir la crítica social con la crítica del conocimiento.

Cassava-to-Attiéké Transformation: A Diagnosis Study in Banfora, Bobo Dioulasso and Ouagadougou
Authors: Kalizeta SAWADOGO , Georges YE Siédouba , Hounsouho LINGANI Abdel Kader , Sié KAM
Published: October 2024

Cassava is a perishable commodity with a shelf life of less than 3 days after harvest. The general objective of our study is to take stock of the practices and equipment used in the processing of cassava into attiéké. This will subsequently allow us to optimize the operating energy of a mechanized cassava into attiéké processing unit. To do this, a diagnosis was made through a field survey of local processing companies in the cities of Banfora, Bobo Dioulasso and Ouagadougou. Our study focused on 20 processing units selected on the basis of the products manufactured and their geographical area.
The results made it possible to list the equipment used at each stage of processing and their methods of use (manual or mechanized). It appears that in most companies, processing equipment is mainly manual. The inventory of equipment used in cassava processing units in Banfora, Bobo Dioulasso and Ouagadougou showed that graters/crushers are the only motorized equipment used in these units. It is therefore essential to mechanize cassava processing equipment into attiéké as far as possible in order to reduce the arduousness of the work.
Nutritional Assessment and Sub-acute Toxicity Study in Wistar Rats Fed with a Compounded Diet of Roasted Plantain and Fish Sold in Otuoke, Nigeria
Authors: Olufunso Abosede, Uduakobong , Dennis Kpomah, Enyohwo
Published: October 2024

The widespread consumption of roasted plantain and fish (Bolle), a common delicacy in Bayelsa State has raised concerns over potential health risks associated with food processing contaminants such as acrylamides, polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs). The roasted plantain and fish are usually prepared by placing the peeled plantain and the dressed fish on a wired gauze and placed over a burning charcoal. The subacute toxicity study of this diet was investigated using twenty adult male rats averagely weighing 117.22 \(\pm\) 4.48 g. The rats were divided into four groups of five rats per group. Group A (Control), was fed with the standard rat chow, Group B; was fed with only the roasted plantain, Group C; was fed with only the roasted fish, and Group D; was fed with a combination of the roasted plantain and fish. The rats were given free access to the feed and portable water ad-libitum throughout the experimental protocol. Body/organ weight data were recorded before and after the completion of the experimental protocol. On day 15th of the experimental protocol, the rats were euthanized and blood specimens were obtained by cardiac puncture for biochemical analysis. The liver, kidney and heart were dissevered instantaneously and weighed. Findings from the study showed that the roasted plantain-fed group had significantly reduced body weight gain, and increased liver and kidney to body weight ratio (p>0.05). The plasma enzyme activity (AST, ALT and ALP) of the plantain-fed group were also significantly increased (p<0.05) while other groups showed non-significant differences (p>0.05) with the control group. The antioxidant status (CAT, SOD and GPx), haematological parameters (RBC, PCV, Hb, MCV, MCH, MCHC and platelet) of the plantain-fed groups were also significantly decreased (p<0.05) while other groups had non-significant changes (p>0.05) when compared to the control group. Malondialdehyde levels in the roasted plantain-fed group were also significantly increased (p<0.05).

Authors: Anvarovich Mirzakhodjaev Bakhtiyar , Anvar Mirzakhodjaev , Tangatarovna Tajenova Arzigul , Bahadirovich Radzhabov Ismoil
Published: October 2024

Aims: Due to changes in the global climate and the recent increase in spring frosts, which lead to the death of silkworm caterpillars of the first ages due to lack of food, there is an urgent need to find effective and cheap means to replace natural food - mulberry leaf. One of the promising methods is the preservation of mulberry leaf. One of the new and progressive methods of preservation is the method of freeze-dried of mulberry leaf, for the basis of artificial diet.
Place and Duration of Study: The experiments were conducted in the laboratory of the Scientific Research Institute of Sericulture in 2024y.
Methodology: After hatching, the caterpillars were fed artificial food based on freeze-dried mulberry leaf, the food was given once a day, the room temperature was 25-26 ° C, humidity 65-70%. When the caterpillars reached the third age, some of the caterpillars of each breed and hybrid were selected and continued to be fed with artificial diet. The remaining caterpillars were transferred to natural leaf feeding according to a generally accepted method.
Results: The drying time of the mulberry leaf in the freeze-dried mode was 14-18 hours, depending on the uniformity of the leaf layer in the chamber. A recipe for artificial diet was created, in which the content of mulberry leaf powder was 72%. All breeds and hybrids equally well received the developed artificial diet. In breeds and hybrids, the viability of caterpillars was 82-100%. And when switching from artificial diet to a natural leaf, the viability of caterpillars was 63-93%.
Conclusion: All breeds and hybrids equally well accepted the developed artificial food based on freeze-dried mulberry leaf. According to the totality of the results shown, the studied breeds and hybrids are promising for feeding them on artificial feed and breeding appropriate lines and breeds from them.

Published: October 2024

Cowpea is mainly grown in the arid and semiarid regions at the global level. The temperature above 35oC affects the morpho-physiological processes and decreases the biomass. Hence, identification of thermotolerant genotypes is necessary to ensure food security in the face of climate change, allowing farmers to cultivate resilient varieties. In this regard, one hundred ninety-one genotypes were screened for yield attributes under field conditions at Raichur, Karnataka. The crop was exposed to a higher temperature    up to 41oC during the entire crop growth period. The plants experienced high levels of heat stress which led to increase in mean leaf temperature, decreased mean SPAD chlorophyll meter reading (SCMR), total dry matter (TDM) and other yield attributing traits. Tolerant cowpea genotypes which showed minimum reduction in total dry matter compared to susceptible genotypes where identified. The tolerant genotypes IC-402172, EC-458453, EC- 458470, NBC-21, NBC-14, EC-394708, CB-10, IC-458430, IC-249588 and EC-458490 can sustain the temperature up to 35oC without compromising the total dry matter. This can be used for further crop improvement programme to develop themotolerance.

Aims: Root perforations are accidents and complications that can occur during endodontic treatment. With the advent of calcium silicate-based repair cements, there is a possibility to effectively seal and preserve the affected tooth. The objective of this case report was to evaluate the success and repair of a root perforation sealed with a calcium silicate-based repair cement of a tooth that had been indicated for extraction.
Presentation of Case: A 59-year-old healthy female without systemic diseases, presented to the dental service with a fistula, spontaneous pain, and pain upon vertical and horizontal percussion in the tooth 24, which had a metal-ceramic crown, a metal post, and inadequate endodontic treatment. The crown was sectioned, and the post was removed with ultrasonic tips. A perforation in the palatal root and bone resorption were observed through a cone-beam computed tomography (CBCT). The perforation was sealed with MTA HP (Angelus) and the canals were retreated using mechanized systems and filled with BioRoot RCS sealer (Sepdotont) in a single session. The tooth was rehabilitated using a digital workflow based on scanning and 3D printing of the restoration/crown. Follow-up was performed after six and nine months, and the patient showed no painful symptoms upon horizontal and vertical percussion tests, with CBCT showing regression of the bone resorption.
Discussion and Conclusion: The bone repair and the absence of signs and symptoms of periradicular pathologies indicate treatment success after nine months follow up of the root perforation sealed with a calcium silicate-based repair cement.

Published: October 2024

Nephroblastoma (Wilm’s Tumour) is the commonest paediatric renal cancer worldwide. It is uncommon in infants less than six months of age and very rarely seen in neonates.  The uncommon presentation of nephroblastoma in the newborn period of this two month old, depicts the possibility of its sporadic occurrence in this age group. Due to the rarity of such occurrence, there is a risk of misdiagnosis and missed diagnosis. We therefore present this report to raise awareness of its possibility of occurence.

Published: October 2024

The application of Calcium at veraison stage maintain the quality of grapes. Hence to evaluate the effect of Calcium formulations for increasing yield and the shelf life of Manjri Naveen grapes. The experiment was designed as randomized block design (RBD) having seven treatments and four replications (1 replicate = 4 vines). Three calcium formulations were used i.e. CaCl2, CaO, Ca(No3)2 as a dose of (2.5 g/l) and (5 g/l). Foliar application of calcium was done 10 days before harvest at veraison stage. Results obtained from the experiment showed the lowest weight loss was found in bunches of calcium oxide and calcium chloride spray treatments (8.14 %), (8.61 %) respectively, while the highest weight loss (10.36 %) occurred in untreated control. The PLW increased significantly at successive from 1.32 % on 1st day to 10.36 % on 7th day of storage at room temperature. CaO at 5 g/l recorded the lowest fallen berries 2.70 (%), followed by Ca(NO3)2 at 2.5 g/l recorded 3.38 (%). It might be due to calcium accumulated mostly in the rachis and less in the flesh during grape berry development. Yield and quality components like bunch weight, berry weight, total yield/vine, TSS, TSS/Acidity ratio were significantly influenced by calcium spray. Hence from this study it is concluded that the foliar application of CaO at 5 g/l was found to be effective for increasing the shelf life and yield of Manjri Naveen grapes.

Published: October 2024

Aims: This paper shows the contribution of participatory research to upgrade the integration of legumes into cropping systems.
Place and Duration of Study: The investigation is based on survey data collected in 2008 and 2011 (two reference years) and 2021 and 2022 (current situation) in the village of Koumbia in western Burkina Faso.
Methodology: Data was collected through surveys and field measurements. The surveys were conducted with a sample of fifty (50) volunteer farmers. In 2008, 2011 and 2022, the same questionnaire was administered to all 50 farmers. Field measurements with GPS (Global Positioning System) were conducted on crop area.
Results: The results show that the proportion of area under legumes crops increased by 77,38% after 15 years. Other legumes crops (Glycine max and Mucuna sp.) were introduced in addition to those previously grown (groundnuts and cowpeas) by farmers. Surface cropped in sorghum (35.36%) and millet (82.79%) declined while cotton and maize remain the main crops in the zone. The results on farmers’ perception show that they prefer single cropping of legume crops as their insertion modality in the existing farming systems compared to their association with cereals.
Conclusion: The study shows that the role of legumes is increasing in the cropping system, and represents an opportunity to succeed in the agro-ecological transition, even though the intercropping of cereal/legume, which is put forward by the theoretical models of the agro-ecological transition, is still little practiced. The structuration of the legume sector can be a condition for achieving it.

Published: October 2024

Breast cancer is the world's most frequent malignancy among women. Many dietary antioxidants have been shown to help prevent oxidative stress, which has been linked to a variety of diseases, including cancer. Many chronic diseases, such as cancer, can be avoided by eating fruits and vegetables on a regular and balanced basis. The current study's goal is to assess the antioxidant and cytotoxic capabilities of methanolic extracts of Beta vulgaris and Daucus carota against MCF-7 human breast cancer cell lines. Therefore, the aim of the present study was to determine the phytochemical components, antioxidant capacity, total phenolic & flavonoid contents in the methanolic extracts of Beta vulgaris and Daucus carota. Further, MTT assay against breast cancer cell line (MCF-7) was performed for the evaluation of cytotoxic activity. The majority of secondary metabolites were found in both the aqueous and methanolic extracts of Beta vulgaris and Daucus carota. Beta vulgaris and Daucus carota have different total phenolic and flavonoid contents. TLC results showed many spots having different Rf values. Moreover, we observe comparable cytotoxic activity in both the extracts against MCF-7 cell lines. Our results reveal that the methanolic extracts of Beta vulgaris and Daucus carota has effective phytochemical constituents, antioxidant and anticancer activity. The total phenolic and flavonoid contents vary between Beta vulgaris and Daucus carota. Further studies are needed to evaluate the chemopreventive potentials of the Beta vulgaris and Daucus carota extract when used alone or in combination with doxorubicin to mitigate the toxic side-effects of the latter.

Published: April 2018

Selective doping of optically active ions into the nanocrystalline phase(s) of glass ceramics is of interest for photoluminescence (PL) applications to control the energy transfer (ET) processes between dopants on the nanometer length scale. Here, the focus is on explaining the essential knowledge of the distribution of two groups of active ions: transition metal (Ni2+ and Cr3+) and rare earth (Yb3+ and Er3+) ions, which are doped into i) single‐phase Ga2O3 and ii) dual‐phase Ga2O3 and YF3 nanocrystals (NCs). These NCs are obtained by thermally crystallizing ternary silicate‐ and quinary fluorosilicate‐based glasses, respectively. It is found that the two types of active ions can successfully be doped into Ga2O3 NCs, resulting in enhanced ET between the dopants because of the small separation distance of, e.g., <10 Å, whereas ET is significantly suppressed when Ga2O3 and YF3 NCs are coprecipitated. In this case, the studied rare earth ions have a high propensity for being selectively doped in YF3 NCs. The studied transition‐metal ions can always be found in Ga2O3 NCs irrespective of the presence of the fluoride phase. The selective doping and the ET between the two types of active ions can be controlled simultaneously on annealing. This may allow for the achievement of diverse PL properties, such as ultrabroadband near‐infrared and upconversion‐mediated Stokes emissions.
Iridium‐Catalyzed Annulation Reactions of Thiophenes with Carboxylic Acids: Direct Evidence for a Heck‐type Pathway
Authors: Tan Guangying , You Qiulin , Lan Jingbo , You Jingsong
Published: April 2018

The functionalization of thiophenes is a fundamental and important reaction. Herein, we disclose iridium‐catalyzed one‐pot annulation reactions of (benzo)thiophenes with (hetero)aromatic or α,β‐unsaturated carboxylic acids, which afford thiophene‐fused coumarin‐type frameworks. Dearomatization reactions of 2‐substituted thiophenes with α,β‐unsaturated carboxylic acids deliver various thiophene‐containing spirocyclic products. The occurrence of two interconnected reactions provides direct evidence for a Heck‐type pathway. The mechanistic scenario described herein is distinctly different from the SEAr and concerted metalation–protodemetalation (CMD) pathways encountered in the well‐described oxidative C−H/C−H cross‐coupling reactions of thiophenes with other heteroarenes.
Divergent Control of Point and Axial Stereogenicity: Catalytic Enantioselective C−N Bond‐Forming Cross‐Coupling and Catalyst‐Controlled Atroposelective Cyclodehydration
Authors: Kwon Yongseok , Chinn Alex J. , Kim Byoungmoo , Miller Scott J.
Published: April 2018

Catalyst control over reactions that produce multiple stereoisomers is a challenge in synthesis. Control over reactions that involve stereogenic elements remote from one another is particularly uncommon. Additionally, catalytic reactions that address both stereogenic carbon centers and an element of axial chirality are also rare. Reported herein is a catalytic approach to each stereoisomer of a scaffold containing a stereogenic center remote from an axis of chirality. Newly developed peptidyl copper complexes catalyze an unprecedented remote desymmetrization involving enantioselective C−N bond‐forming cross‐coupling. Then, chiral phosphoric acid catalysts set an axis of chirality through an unprecedented atroposelective cyclodehydration to form a heterocycle with high diastereoselectivity. The application of chiral copper complexes and phosphoric acids provides access to each stereoisomer of a framework with two different elements of stereogenicity.
A Biomimetic Nickel Complex with a Reduced CO2 Ligand Generated by Formate Deprotonation and Its Behaviour towards CO2
Authors: Zimmermann Philipp , Hoof Santina , Braun‐Cula Beatrice , Herwig Christian , Limberg Christian
Published: April 2018

Reduced CO2 species are key intermediates in a variety of natural and synthetic processes. In the majority of systems, however, they elude isolation or characterisation owing to high reactivity or limited accessibility (heterogeneous systems), and their formulations thus often remain uncertain or are based on calculations only. We herein report on a Ni−CO22− complex that is unique in many ways. While its structural and electronic features help understand the CO2‐bound state in Ni,Fe carbon monoxide dehydrogenases, its reactivity sheds light on how CO2 can be converted into CO/CO32− by nickel complexes. In addition, the complex was generated by a rare example of formate β‐deprotonation, a mechanistic step relevant to the nickel‐catalysed conversion of HxCOyz− at electrodes and formate oxidation in formate dehydrogenases.

Published: April 2018

Pyrene end‐labeled star poly(ɛ‐caprolactone)s (PCLs) with polyhedral oligomeric silsesquioxane (POSS) core were prepared by combination of copper(I)‐catalyzed azide–alkyne cycloaddition (CuAAC) click chemistry and ring‐opening polymerization techniques. First, ɛ‐caprolactone (ɛ‐CL) is polymerized by using 1‐pyrene methanol as initiator and stannous octoate as catalyst to obtain α‐pyrene‐ω‐hydroxyl telechelic PCL with different chain lengths. Then, its hydroxyl group is converted to acetylene functionality by esterification reaction with propargyl chloroformate. Finally, the CuAAC click reaction of α‐pyrene‐ω‐acetylene telechelic PCL with POSS‐(N3)8 leads to corresponding pyrene end‐labeled star‐shaped PCLs. The successful synthesis of pyrene end‐labeled star polymers is clearly confirmed by 1H‐nuclear magnetic resonance, Fourier transform infrared, gel permeation chromatograph, differential scanning calorimeter, and thermogravimetric analysis. Furthermore, non‐covalent interactions of obtained star polymers with fullerene are investigated in liquid media. Based on Raman spectroscopy and visual investigations, the star polymer having shorter chain length exhibited better and more stable dispersion with fullerene. The amount of pyrene units present per polymer chains can directly influence the dispersion stability of fullerene. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46520.

Empathy and face processing in adults with and without autism spectrum disorder
Authors: Rigby Sarah N. , Stoesz Brenda M. , Jakobson Lorna S.
Published: April 2018

Many factors contribute to social difficulties in individuals with autism spectrum disorder (ASD). The goal of the present work was to determine whether atypicalities in how individuals with ASD process static, socially engaging faces persist when nonrigid facial motion cues are present. We also sought to explore the relationships between various face processing abilities and individual differences in autism symptom severity and traits such as empathy. Participants included 16 adults with ASD without intellectual impairment and 16 sex‐ and age‐matched controls. Mean Verbal IQ was comparable across groups [t(30) = 0.70, P = 0.49]. The two groups responded similarly to many of the experimental manipulations; however, relative to controls, participants with ASD responded more slowly to dynamic expressive faces, even when no judgment was required; were less accurate at identity matching with static and dynamic faces; and needed more time to make identity and expression judgments [F(1, 30) ≥ 6.37, P ≤ 0.017, ηp2 ≥ 0.175 in all cases], particularly when the faces were moving [F(1, 30) = 3.40, P = 0.072, ηp2 = 0.104]. In the full sample, as social autistic traits increased and empathic skills declined, participants needed more time to judge static identity, and static or dynamic expressions [0.43 < |rs| < 0.56]. The results suggest that adults with ASD show general impairments in face and motion processing and support the view that an examination of individual variation in particular personality traits and abilities is important for advancing our understanding of face perception.

Lay Summary

Our findings suggest that people with ASD have problems processing expressive faces, especially when seen in motion. It is important to learn who is most at risk for face processing problems, given that in the general population such problems appear to be linked to impaired social skills and empathy. By studying relationships between different abilities and traits, we may be able to find better ways to diagnose and support all people on the autism spectrum.
Effect of homogeneous static magnetic treatment on the adsorption capacity in maize seeds (Zea mays L.)
Authors: Torres Javier , Socorro Alfredo , Hincapié Eduard
Published: April 2018

In order to analyze the treatment of seeds with homogeneous static magnetic field on the water adsorption process, an experimental‐theoretical study of hygroscopic equilibrium in maize seeds (Zea mays L. cv. ICAV305) was carried out. Four treatments with magnetic induction of 80.0, 120.0, 160.0, and 200.0 mT were applied for 10 min, and there was a control group without treatment. The doses were selected because they showed a decrease in mean germination time. Treated seeds were subjected to an environment with a stable temperature of 30.0 °C ± 0.1 °C and atmospheres of different relative humidity (h), using eight salt solutions saturated with water activity between 0.216 and 0.970. Curves were adjusted using the D'Arcy‐Watt and modified Oswin models. It was found that the magnetic treatment of seeds affects adsorption, and the 200 mT—10 min one was the most significant in affecting the mechanisms of adsorption of water, and increasing the number of adsorption sites connected to weak binds with D'Arcy‐Watt's adjustment. Using the Oswin model for simulation, we verified that the magnetic stimulus affected the enthalpy of adsorption and the mechanism of incorporation of water vapor molecules to the structure of seminal cover. These results show that the magnetic pre‐treatment of seeds has an effect on a seed's specific biophysical and physiological processes in the early stages of germination.

Three anthracene‐based Schiff base complexes, R1–R3 (R1 = (E)‐N´‐((anthracen‐10‐yl)methylene)benzohydrazide; R2 = (E)‐1‐((anthracen‐10‐yl)methylene)‐4‐phenylsemicarbazide; and R3 = (E)‐1‐((anthracen‐10‐yl)methylene)‐4‐phenylthiosemicarbazide) were synthesized from 9‐anthracenecarboxaldehyde, benzohydrazide, 4‐phenylsemicarbazide and 4‐phenylthiosemi‐carbazide respectively, and characterized by various spectral techniques. The absorption spectral characteristics of R1–R3 were bathochromically tuned to the visible region by extending the π conjugation. These target compounds were weakly fluorescent in tetrahydrofuran (THF) solution because of rapid isomerization of the C=N double bond in the excited state. However, the aqueous dispersion of R1–R3 in the THF/water mixture by the gradual addition of water up to 90% resulted in an increase in the fluorescence intensity mainly due to aggregation‐induced emission enhancement (AIEE) properties. The formation of nanoaggregates of R1–R3 were confirmed by scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques. The compounds R1–R3 are ideal probes for the fluorescence sensing of bovine serum albumin (BSA) and breast cancer cells by optical cell imaging.
Multiclass partial least squares discriminant analysis: Taking the right way—A critical tutorial
Authors: Pomerantsev Alexey L. , Rodionova Oxana Ye.
Published: April 2018

Here, the theory of the multi‐class partial least squares discriminant analysis (PLS‐DA) is presented. A distinct feature of this theory is that it does not utilize PLS scores but is entirely based on the predicted dummy responses. It is shown that the results of the multi‐class PLS‐DA can be presented in a straightforward way by projecting the response matrix on the “super‐score” space by means of principal component analysis. Two approaches to discrimination are considered: the hard and the soft way of allocation. Correspondingly, 2 versions of PLS‐DA are presented: the conventional hard PLS‐DA, and the newly introduced soft PLS‐DA that seems to be a novel approach in chemometrics. The quality of classification is assessed using the figures of merit (sensitivity, specificity, and efficiency). It is shown how these characteristics are used for the selection of the model complexity. A number of practical problems are investigated, such as unbalanced sizes of classes, comparison of the discriminant and the class‐modeling methods and authentication by the “one against all” strategy. The paper is illustrated by real‐world and simulated examples.

Published: April 2018

The synthesis and characterization of a dinuclear bis(thiosemicarbazone) cobalt complex [Co2L2(NCS)2] is reported. This complex exhibits significant catalytic activity for hydrogen production in DMF by using triethylammonium (Et3NHBF4) as the proton source. Cyclic voltammetry data allowed a maximum turnover frequency of 130 s−1 for 1 m proton concentration to be determined. The catalytic nature of the process and the production of dihydrogen were confirmed by gas analysis during controlled potential electrolysis experiments. Quantum chemical calculations show that the complex displays a ligand‐assisted metal‐centered reactivity and supports a catalytic mechanism involving ligand‐based reduction and protonation steps followed by metal‐centered processes.

Published: April 2018

A novel series of indole‐2‐carbohydrazide derivatives were synthesized, characterized, and evaluated for their antiproliferative activities against two cancer cell lines, HCT116 and SW480, and a normal human fetal lung fibroblast cell line, MRC‐5. Among this series, compound 24 f displayed potent cytotoxic activities in vitro against HCT116 and SW480 cell lines with GI50 values of 8.1 and 7.9 μm, respectively, and was inactive against MRC‐5 cells. The newly synthesized compounds were also evaluated for anti‐angiogenesis capabilities by chick chorioallantoic membrane, human umbilical vein endothelial cell (HUVEC) migration, and endothelial microtubule formation assays. Moreover, the effects of 24 f on the vascular endothelial growth factor receptor‐2 and the signaling pathway in HUVECs indicated that this compound inhibits VEGFR‐2 and its downstream related proteins. These results indicate that compound 24 f, as well as the other derivatives, are promising inhibitors of angiogenesis.

Published: April 2018

Introduction

The rising incidence of oropharyngeal squamous cell carcinoma (OPSCC) in New Zealand is due to an increase in the numbers of human papilloma virus (HPV)–associated OPSCC. We evaluated the impact of positive p16 immunohistochemistry, as a surrogate for HPV positivity, on OPSCC outcomes after primary intensity‐modulated radiotherapy (IMRT) with or without concurrent chemotherapy.

Methods

Retrospective review was undertaken of electronic medical records of 90 patients with OPSCC who received primary IMRT with or without chemotherapy between 2008 and mid‐2015 at the Regional Cancer Centre, Waikato Hospital, Hamilton, New Zealand.

Results

Median age was 57.5 years. Immunohistochemistry for p16 was positive in 53 (59%) OPSCC while 37 (41%) had negative or unknown p16 status. Median radiotherapy dose was 70 Gy. Chemotherapy was administered to 78 (87%) patients, most receiving high‐dose cisplatin. Nine patients had residual disease following treatment completion. Seven patients relapsed, and 26 died during the study period. Five patients with p16‐positive OPSCC had persistent or recurrent disease. Actuarial 3‐year locoregional control, disease‐free survival, and overall survival for all patients were 80.7%, 74.7%, and 77.1%, respectively. Among p16‐positive OPSCC patients, 3‐year locoregional control, disease‐free survival, and overall survival were 89.5%, 80.8%, and 90.9%, respectively.

Conclusion

Outcomes after IMRT for OPSCC at Waikato Hospital are in line with the reported literature. Human papilloma virus–related OPSCC has better outcomes compared with patients with unknown or HPV‐unrelated OPSCC. Trials are underway evaluating reduced intensity of treatment for HPV‐related OPSCC.
Approximation of General Facets by Regular Facets with Respect to Anisotropic Total Variation Energies and Its Application to Crystalline Mean Curvature Flow
Authors: Giga Yoshikazu , Požár Norbert
Published: April 2018

We show that every bounded subset of a euclidean space can be approximated by a set that admits a certain vector field, the so‐called Cahn‐Hoffman vector field, that is subordinate to a given anisotropic metric and has a square‐integrable divergence. More generally, we introduce a concept of facets as a kind of directed sets, and show that they can be approximated in a similar manner.

We use this approximation to construct test functions necessary to prove the comparison principle for viscosity solutions of the level set formulation of the crystalline mean curvature flow that were recently introduced by the authors. As a consequence, we obtain the well‐posedness of the viscosity solutions in an arbitrary dimension, which extends the validity of the result in the previous paper.© 2018 Wiley Periodicals, Inc.
