Este estudio tiene por objetivo describir los significados asociados a la corporalidad que tienen mujeres en tratamiento de cáncer de mama y que participan en un grupo de apoyo, considerando tres dimensiones del cuerpo: la imagen corporal, la feminidad y la sexualidad. Al ser un estudio cualitativo consta de una entrevista semiestructurada de carácter grupal a cinco mujeres participantes del grupo de apoyo “Nueva Vida Rancagua”, realizándose un análisis interpretativo de contenido, el que permitió visualizar la problemática desde la visión de las propias protagonistas.
Los hallazgos del estudio dan paso a nuevas dimensiones que reflejan cómo los distintos significados del cáncer afectan sus experiencias respecto a la corporalidad, acrecentado por discursos y otredades que representan actitudes y comportamientos de una sociedad o comunidad frente a la enfermedad. Se analizan estos discursos en función de los grupos de apoyo, tanto en su impacto perjudicial para desarrollo de la enfermedad, considerando categorías como el abandono, la angustia, el miedo, el rechazo a su nueva realidad; como en su impacto positivo, a través de categorías como la empatía y la necesidad de encontrar entendimiento y contención, proporcionado por las redes que generan y el acompañamiento que se genera en sus círculos.
Dubcon
Authors: Popova Milena 
Published: October 2021

How the treatment of sexual consent in erotic fanfiction functions as a form of cultural activism.
Sexual consent is—at best—a contested topic in Western societies and cultures. The #MeToo movement has brought public attention to issues of sexual consent, revealing the endemic nature of sexual violence. Feminist academic approaches to sexual violence and consent are diverse and multidisciplinary—and yet consent itself is significantly undertheorized. In Dubcon, Milena Popova points to a community that has been considering issues of sex, power, and consent for many years: writers and readers of fanfiction. Their nuanced engagement with sexual consent, Popova argues, can shed light on these issues in ways not available to either academia or journalism.
Popova explains that the term “dubcon” (short for “dubious consent”) was coined by the fanfiction community to make visible the gray areas between rape and consent—for example, in situations where the distribution of power may limit an individual's ability to give meaningful consent to sex. Popova offers a close reading of three fanfiction stories in the Omegaverse genre, examines the “arranged marriage” trope, and discusses the fanfiction community's response when a sports star who was a leading character in RPF (real person fiction) was accused of rape. Proposing that fanfiction offers a powerful discursive resistance on issues of rape and consent that challenges dominant discourses about gender, romance, sexuality, and consent, Popova shows that fanfiction functions as a form of cultural activism.

Provocative, hopeful essays imagine a future that is not reduced to algorithms.
What is human flourishing in an age of machine intelligence, when many claim that the world's most complex problems can be reduced to narrow technical questions? Does more computing make us more intelligent, or simply more computationally powerful? We need not always resist reduction; our ability to simplify helps us interpret complicated situations. The trick is to know when and how to do so. Against Reduction offers a collection of provocative and illuminating essays that consider different ways of recognizing and addressing the reduction in our approach to artificial intelligence, and ultimately to ourselves.
Inspired by a widely read manifesto by Joi Ito that called for embracing the diversity and irreducibility of the world, these essays offer persuasive and compelling variations on resisting reduction. Among other things, the writers draw on Indigenous epistemology to argue for an extended “circle of relationships” that includes the nonhuman and robotic; cast “Snow White” as a tale of AI featuring a smart mirror; point out the cisnormativity of security protocol algorithms; map the interconnecting networks of so-called noncommunicable disease; and consider the limits of moral mathematics. Taken together, they show that we should push back against some of the reduction around us and do whatever is in our power to work toward broader solutions.

Published: October 2021

Lilium is a perennial bulbous flower of Lily family Liliaceae, with high ornamental and economic value. However, Lily is vulnerable to virus infection, which seriously affects the yield and quality of Lily, and poses a great threat to the production, sales, especially export of Lily, and has caused huge economic losses to the related industries. Therefore, the research on lily virus removal methods and virus detection technology has important practical significance to improve the ornamental value and economic value of lily.
In this study, the filaments of four susceptible lily varieties,' Valdisole' (A),'Adoration'(LA),' Ice Cube'(OT) and ‘Zantriana’ (O), were used as explants. The filaments of lily were divided into three parts, namely, top, middle, and base. In this paper, the virus detection of tissue culture seedlings induced by lily filaments was carried out by using DAS-ELISA and RT-PCR, and the removal effects of Cucumber mosaic virus,(CMV) and lily symptomless virus (LSV), two common viruses in lily, were explored, and the two detection technologies were compared.
The results showed that the success rate of tissue culture seedlings induced by filament base was the highest, and CMV virus could be basically removed. RT-PCR detection is more sensitive than DAS-ELISA detection, but RT-PCR detection requires higher test conditions and technology. Therefore, appropriate virus detection methods can be selected according to actual conditions and severity.

Aims: Estimate the population density of deer in the municipality of Tzucacab, Yucatán in the periods of 2003-2004, 2007-2008 and 2008-2009, determine the use of the habitat by these populations and the sustainability of the deer harvest from the estimated population densities.
Study Design: A descriptive and vertical free-living deer population study was carried out in southern Yucatan, Mexico over a three-year period.
Methodology: The map of the municipality of Tuzcacab was zoned in quadrants of 36 km2, completing a total of 36 quadrants; Unrestricted random sampling was applied to select seven quadrants in the period from 2003 to 2004 and 18 in each annual period between 2007 and 2009. Population samplings were carried out by applying three population estimation methods: direct sighting in a linear transect of 5 km in length, count of tracks in transect except period 2003-2004 and faecal pellets group count in plots. The evaluation of the use of habitat was carried out using the Bonferroni intervals, from the data of faecal pellets count. The evaluation of the deer harvest was carried out using the sustainable harvest model.
Results: The population densities were different in each method, the density by the excreta count was 4.63 ± 2.49 deer / km2 in 2003-2004, 0.294 ± 0.198 deer / km2 in 2007-2008, and in the year 2008-2009 was 0.419 ± 0.0000085 deer / km2. Habitat use in 2007-08 and 2008-2009 was higher in the tropical forest, lower in agriculture and similar to that expected in secondary succession forest (acahual). The values of sustainable harvest, taking as a value the density per count of excreta in the plot because it showed the highest statistical precision, in the period 2003-04 it is sustainable, but in the period from 2007 to 2009 it is not sustainable.
Conclusion: The population densities of deer (O. virginianus and M. americana) in Tuzcacab by means of the excreta count method, have decreased significantly. The habitat use preference is the tropical forest. The deer harvest in the period from 2007 to 2009 is not sustainable.
The Histopathology of Carcinoma Breast with Special Reference to p53 Marker
Authors: Balakrishnan Meera 
Published: October 2021

Introduction: Breast cancer is one of the most common cancers among women in the world. The high incidence of breast carcinoma in women has inspired a thorough investigation of potentially modifiable risk variables (clinical parameters, morphological type, and biochemical indicators) for prognosis, preventative tactics, and treatment options. One of the most important prognostic indicators for breast cancer is p53.
Aims and Objectives: The goal of this study was to use immunohistochemistry to assess the prevalence of p53 mutant protein in breast cancer, correlate the results with clinical and histological parameters, and establish its impact on axillary node metastasis.
Materials and Methods: A clinicopathological study of 50 cases of infiltrating ductal carcinoma of the breast was performed using immunohistochemistry to examine for p53 mutant protein expression.
Results: Percentage of p53 immunohistochemical positivity in this study was 22%, which is similar to other studies' reported statistics. In both the positive and negative cases of lymph node metastases, immunohistochemical data revealed an equivocal p53 status. In compared to p53 negative cases, the carcinomas with p53 positivity showed aggressive characteristics, such as greater size and higher grade. Patients with significant lymphocytic reactions to tumours, patients under 35 years of age, and those with tumours on the left side had a higher chance of receiving a positive p53 status. This study clearly shows that breast cancers with high p53 expression are generally aggressive tumours with a poor prognosis and a poor response to endocrine treatment and chemotherapy.

AbstractThe ability to operate in aqueous environments makes poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate), PEDOT:PSS, based organic electrochemical transistors (OECTs) excellent candidates for a variety of biological applications. Current research in PEDOT:PSS based OECTs is primarily focused on improving the conductivity of PEDOT:PSS film to achieve high transconductance (gm). The improved conductivity and electronic transport are attributed to the formation of enlarged PEDOT‐rich domains and shorter PEDOT stacking, but such a change in morphology sacrifices the ionic transport and, therefore, the doping/de‐doping process. Additionally, little is known about the effect of such morphology changes on the gate bias that makes the maximumgm(), threshold voltage (VT), and transient behavior of PEDOT:PSS based OECTs. Here, the molecular packing and nanostructure of PEDOT:PSS films are tuned using ionic liquids as additives, namely, 1‐Ethyl‐3‐methylimidazolium (EMIM) as cation and anions of chloride (Cl), trifluoromethanesulfonate (OTF), bis(trifluoromethylsulfonyl)imide (TFSI), and tricyanomethanide (TCM). It is demonstrated that an optimal morphology is realized using EMIM OTF ionic liquids that generate smaller fibril‐like PEDOT‐rich domains with relatively loose structures. Such optimal morphology improves ion accessibility, lowering the gate bias required to completely de‐dope the channel, and thus enabling to achieve high transconductance, fast transient response, and at lower gate bias window simultaneously.

AbstractElectroluminescent (EL) quantum dot light‐emitting diode (QLED) array for pixel‐on‐demand display containing 75 emitting zones (5 × 15) is demonstrated by a single larger‐area QD EL film (5 cm × 5 cm). To fabricate a passive‐matrix (PM) QLED display, the 5 × 15 QLED emitting array without any pre‐patterned bank is directly defined by the overlapping area of crossing ITO and Al finger electrodes. As‐prepared emitting array has obvious electrical crosstalk, making the on‐demand pixels emit together with some neighbors undriven, which is ascribed to a carrier leakage to the neighbor pixels. By applying the common electrode voltage to the unselected rows, the undesired electrical crosstalk has been thoroughly suppressed. This study first demonstrated that a PM‐QLED display can be feasibly realized by a bank‐free quantum dot film prepared from a coating process without any pixel defining layer or complex driving condition.

AbstractPerovskite solar cells (PSCs) exhibit the steepest growth in power conversion efficiency among the existing photovoltaic technologies. However, a wide range of factors restrict the commercial viability of PSCs as a renewable energy source. This article reviews the latest progress in PSC devices including innovative light‐harvesting perovskite materials and advanced interfacial layers, and the foremost challenges. The most promising remedial solutions to challenges are also discussed. For the realization of a high performing and eco‐friendly stabilized perovskite photovoltaic device, a combinational method involving multiple restorative solutions is required. A specific emphasis is given to unveiling interesting perovskite properties, and device fabrication approaches to the solutions. These remedies and strategies may help researchers to select appropriate methods and design their experiments to obtain a high photo‐conversion efficiency in photovoltaic devices with enhanced stability as compared to conventional photovoltaic devices.

Published: October 2021

AbstractDie Kombination aus elektrogenerierter Chemilumineszenz (ECL) und Aptamer‐gesteuerter Indikatorfreisetzung (gAID) aus magnetischen mesoporösen Silica‐Nanopartikeln, die in mit Poly(ethylenglycol) und N‐(3‐Triethoxysilylpropyl)diethanolamin funktionalisiertes Glasfaserpapier eingebettet sind, ermöglichte die Entwicklung eines Schnelltests, mit dem sich Penicillin direkt in verdünnter Milch bis auf 50±9 ppt in <5 min nachweisen lässt. Die kovalente Bindung der Aptamer‐Kappe an das Siliciumdioxid‐Gerüst ermöglichte den Verschluss der Poren durch nicht‐kovalente elektrostatische Wechselwirkungen mit Oberflächen‐Aminogruppen. Die Bindung von Penicillin führte zu einer Faltung des Aptamers, wodurch der zuvor in das Material geladene ECL‐Reporter Ru(bpy)32+freigesetzt wurde und nach lateralem Fluss von einer Smartphone‐Kamera nach elektrochemischer Anregung mit einer in einen 3D‐gedruckten Halter eingesetzten Siebdruckelektrode detektiert wird. Der Ansatz ist einfach, generisch und bietet Vorteile hinsichtlich Empfindlichkeit, Messunsicherheit und Robustheit gegenüber konventioneller Fluoreszenz‐ oder elektrochemischer Detektion, insbesondere für Point‐of‐Need‐Analysen anspruchsvoller Matrices und Analyten im Ultraspurenbereich.

Published: October 2021

AbstractThe borane FmesBH2reacts in a three‐component reaction with an isonitrile and a small series of organonitriles to give rare examples of the class of dihydro‐1,4,2‐diazaborole derivatives. In a related way, annulated BN‐indolizine derivatives became conveniently available, as were dihydro‐1,4,2‐oxaza‐ or thiazaborole derivatives. The nucleophilic framework of a dihydro‐1,4,2‐diazaborole example allowed for an uncatalyzed acylation reaction. It also served as a 1,3‐dipolar reagent and underwent a [3+2] cycloaddition/[4+2] cycloreversion sequence when treated with methyl propiolate to give the respective pyrrole product. The [3+2] cycloaddition product of a dihydro‐1,4,2‐diazaborole derivative with N‐phenylmaleimide was isolated and its heterobicyclo[2.2.1]heptane derived structure characterized by X‐ray diffraction.

Published: October 2021

AbstractStrategic replacement of protons with fluorine atoms or functional groups with fluorine‐containing fragments has proven a powerful strategy to optimize the activity of therapeutic compounds. For this reason, the synthetic chemistry of organofluorides has been the subject of intense development and innovation for many years. By comparison, the literature on fluorine biocatalysis still makes for a slim chapter. Herein we introduceS‐adenosylmethionine (SAM) dependent methyltransferases as a new tool for the production of fluorinated compounds. We demonstrate the ability of halide methyltransferases to form fluorinated SAM (S‐adenosyl‐S‐(fluoromethyl)‐L‐homocysteine) fromS‐adenosylhomocysteine and fluoromethyliodide. Fluorinated SAM (F‐SAM) is too unstable for isolation, but is accepted as a substrate by C‐, N‐ and O‐specific methyltransferases for enzyme‐catalyzed fluoromethylation of small molecules.

AbstractBy using diazonaphthoquinones and anilines as key reagents and through a point‐to‐axis chiral transfer strategy, the atroposelective synthesis via asymmetric C(sp2)−H bond insertion reaction of arenes has been realized under rhodium catalysis, providing the resulting biaryl atropisomers in moderate to excellent yields with good enantiomeric ratios (up to 99:1). Further elaboration indicates this type of axially biaryl scaffold may have promising potentials in developing novel chiral ligands.
A Five‐Coordinate Compound with Inverted Ligand Field: An Unprecedented Geometry for Silver(III)

Published: October 2021

AbstractBy using suitable synthetic procedures, we have first isolated the square‐planar organosilver(III) compounds [PPh4][trans‐(CF3)2AgX2] [X=Cl (1 a), Br (2 a)]. The geometry and stereochemistry of the chloro‐derivative 1 a have been unambiguously established by single‐crystal X‐ray diffraction (SC‐XRD) methods. Following our calculations on the relative stability of the cis‐/trans‐[(CF3)2AgX2]− couples (X=F, Cl, Br, I), the experimentally obtained compounds 1 a and 2 a appear to be kinetically favored stereoisomers. They display some tendency to associate an additional X− ligand affording rare five‐coordinate AgIII species [(CF3)2AgX3]2−. Interestingly, compound [PPh4]2[(CF3)2AgBr3] (3) has been identified by SC‐XRD methods as the first AgIII derivative with trigonal symmetry in general and trigonal bipyramidal geometry in particular. This unusual five‐coordinate species also exhibits inverted ligand field.
All‐aromatic ester‐based thermosets: The effect of crosslinking in the nematic or isotropic state
Authors: Xu Hongli , Bijleveld Johan , Dingemans Theo J. 
Published: October 2021

AbstractWe'll report on two series all‐aromatic main‐chain reactive oligomers that can be crosslinked in either the nematic phase or in the isotropic phase. This series is unique in that both model systems have an identical backbone geometry, comprised of hydroquinone with or without a phenyl substituent and phenyl substituted terephthalic acid. Crosslinking the oligomers (Mn of 1–9 kg/mol) via maleimide end‐groups in the nematic or isotropic phase yields networks with similar crosslink densities (Mc) and similar thermal properties. Crosslinked films exhibit high decomposition temperatures (>395°C) and amorphous thermoset films exhibit Tg's in the 141–190°C range whereas nematic thermoset films give Tg's that range from 143 to 176°C, as measured by DMTA. However, the phase type appears to have a major effect on the stress–strain behavior of the films. All films prepared by crosslinking un‐aligned nematic oligomers show poor stress–strain behavior (σ = 20–63 MPa, ε = 0.5%–5.4%), whereas crosslinking the amorphous oligomers results in films with excellent stress–strain properties (σ = 94–97 MPa, ε = 7.1%–13.3%). The superior toughness of the cured amorphous films can be attributed to the larger free volume induced by steric crowding of the phenyl substituents in the polymer repeat unit.
