¿Autocastigo o cuerpos en resistencia? Luchas en y por la periferia de la ciudad
Authors: García Martha Cecilia 
Published: September 2021

Este artículo analiza las protestas sociales que fueron acompañadas de acciones performáticas con rasgos religiosos que implicaron violencias corporales autoinfligidas, como actos de rebeldía en los que se usa el cuerpo como «hecho político» atravesado por un interés colectivo de cambio. Los protagonistas de estas acciones fueron pobladores periurbanos que develaron sus malestares ante la manera como la urbe, Bogotá, se expandió sobre sus contornos rurales, en un proceso que no ha estado exento de violencias en su pretensión de imponer la urbanidad —léase civilización, modernización, industrialización y progreso— sobre el espacio, los actores y las interacciones rurales, y tender mantos de olvido sobre la rurbanización y la bidireccionalidad de estos procesos.
Abstract: This article analyzes social protests involving performative actions with religious features, such as self-inflicted bodily violence, as acts of rebellion in which the body is used as a “political fact” crossed by a collective interest of change. The protagonists of these actions were peri-urban residents who evidenced their discomfort with the city, Bogotá, and how it expanded over its rural surroundings. In fact, the imposition of urbanity—be it civilization, modernization, industrialization or progress—has not been free of violence over the space, actors, and rural interactions, nor has been the imposition of oblivion on the bidirectionality of the rurbanization process.
Keywords: social protests, extra-institutional participation, bodily violences, urban expansion.
Negros, LGBTI e periféricos: o impacto das relações entre movimentos na consolidação de ativismos interseccionais
Authors: Zanoli Vinícius 
Published: September 2021

Neste artigo, baseado em investigação etnográfica realizada entre 2015 e 2019, discuto os impactos das relações entre movimentos sociais na consolidação de um ativismo interseccional. Trata-se de uma análise das redes nas quais atua o Aos Brados, um coletivo LGBTI, negro e da periferia fundado há mais de 20 anos em Campinas (São Paulo, Brasil). Aqui, demonstro como o grupo, ao circular por uma teia que conecta atores e movimentos distintos, passa a aderir e ressignificar noções e práticas políticas que circulam em tal rede. Ao analisar as atividades culturais que passaram a realizar a partir de 2008, evidencio a importância das relações entre ativismos na consolidação de uma identidade política coletiva e de um modo de atuar que valoriza as interseccionalidades, fato pouco explorado pela literatura sobre movimento LGBTI, em particular, e sobre movimentos sociais, de modo geral.
Black, LGBTI and from the Favelas: The Impact of the Relationships between Movements in the Consolidation of Intersectional Activisms
Abstract: In this article, based on an ethnographic investigation carried between 2015 and 2019, I address the impact of the relationships between social movements in the consolidation of an intersectional activism. The analysis is centered on the political networks of a black, peripheric and LGBTI organization: Aos Brados; founded in 1998 in Campinas (São Paulo, Brazil). Here, I demonstrate how, while moving through a web that connects different movements, the group reframes notions and practices circulating in this network. Through the analysis of the cultural activities that the group organizes since 2008, I reveal the significance of the relationships between social movements in the strengthening of a collective political identity and a form of acting that invests in intersectionality; a fact underexplored in the literature.

La Marcha del Orgullo en El Salvador: (Re)Construcción de la memoria, del mito fundador a la realidad histórica
Authors: Maire Thierry 
Published: September 2021

La Marcha del Orgullo en El Salvador, la más antigua del istmo centroamericano, tiene su narrativa anclada en un hecho histórico nacional, estrechamente ligado a la guerra civil que abrumó al país durante los años 80. El concepto de las marchas deriva de los acontecimientos de EE. UU. Entonces, ¿por qué la marcha salvadoreña se presenta como una manifestación de conmemoración de un hecho nacional más que en relación con su antecesora estadounidense, particularmente en un país tan dependiente del gigante del Norte? Para responder a ese cuestionamiento, investigué qué tanto los miembros de la diversidad sexual en San Salvador conocen sobre la historia de su marcha, de su relación con ese hecho nacional y de la Gay Pride (Orgullo Gay) neoyorkina. Agregué a ese análisis cuantitativo llevado a cabo a través de una encuesta en línea, una investigación biográfica alrededor de los fundadores de la marcha. Los vínculos directos, aunque desvanecidos y a veces negados, que los ligan con EE. UU., bien podrían explicar cómo se ideó realmente la Marcha del Orgullo. La narrativa actual procede, entonces, de una re(construcción histórica de la marcha, parcialmente por razones estratégicas, en respuesta al discurso opositor de la derecha conservadora del país.
The ‘Marcha del Orgullo’ in El Salvador: (Re)Building Memory, from the Founding Myth to the Historic Reality
Abstract: The ‘Marcha del Orgullo’ in El Salvador, the oldest in Central America, is supposed to have been founded in tribute to trans people kidnapped and slaughtered during the Civil War in the 80’s. Nonetheless the mere concept of Gay Prides marches took its origin in those realized in the US. Why is it then that El Salvador one should be more autonomous in its foundation? That is especially nagging when one considers the closeness of El Salvador to the US. To solve this enigma, I first undertook an online survey among members of the lgbtiq community in San Salvador, to look at what they knew about the historical narration of their national Pride. I then investigated more into the personalities of the founders of the event. I discovered some very direct relations between them and US-related activists and NGO, which could explain the foundation of the Salvadorian Pride, but I also came to understand why the narrative of the event is framed in order to suppress this US influence due to the opposite stance of far-right conservatives activists.

La desigualdad socioeconómica en América Latina ha modelado múltiples dinámicas de la vida social en la región. Actualmente, estas se han visto intensificadas en el marco de la pandemia de COVID-19, generando graves consecuencias sociales, económicas y sanitarias, con efectos diferenciados para las mujeres, las comunidades étnicas y los territorios rurales a lo largo de la región. Frente a ello, se relatan en el presente artículo cinco experiencias de liderazgo en comunidades étnicas de distintos países de América Latina; experiencias que, desde propuestas alternativas de resistencia comunitaria, han formulado iniciativas para la contención del virus y la crisis socioeconómica que sus comunidades han padecido en este contexto.
Intercultural leaderships in Latin America: durable inequalities and alternative community resistances during the pandemic of COVID-19
Abstract: Socioeconomical inequality in Latin America, has shaped multiple dynamics of the social life in the region. Nowadays, these have been intensified in the frame of the pandemic of COVID-19, generating severe social, economic, and sanitary consequences, with differentiated effects for women, ethnic communities, and rural territories in the region. As a result, in this article, there will be related five leadership experiences among ethnic communities of diverse Latin American countries; from where there has been constructed alternative solutions of community resistance, to contain the virus and the socioeconomical crisis that their communities have hold within the present context.

Apuntes para un cuidado inmanente y despersonalizado. Entre la gestión del VIH y la del SARS-CoV-2
Authors: Cancino Barreto Jaime Sebastián 
Published: September 2021

En este artículo exploro la normalización del cuidado impulsada por la gestión de dos pandemias en Colombia: las provocadas por el VIH y el SARS-CoV-2. Paralelo a ello brindo elementos para un cuidado-otro que tiene como rasgos su inmanencia —que también nombro habitar— y su dimensión despersonalizada. Con esto en mente, rastreo los procedimientos mediante los cuales las instituciones estatales reclaman el monopolio de la gestión de estas pandemias; allí ahondo en la obediencia que solicitan y en el obstáculo que esto representa para el surgimiento de este cuidado-otro. Más adelante estudio lo que llamo “patologización del virus”, explorando algunos de sus rasgos y los efectos políticos que traería, especialmente, la producción de un cuidado securitizado. Finalmente, me concentro en la alianza biopoder y capital, que cobra su mejor expresión en la disyuntiva “economía o vida” y que muestra que la protección biopolítica de la vida es también un hacer producir.
Notes for an immanent and depersonalized care. Between the management of HIV and of SARS-CoV-2
Abstract: This article explores the normalization of care driven by the management of two epidem- ics in Colombia: HIV and SARS-CoV-2. Parallel to this, it provides elements for a different care that has and would have as traits its immanence —which I also name inhabiting— and its depersonal- ized dimension. To do this, I trace the procedures by which state institutions claim a monopoly on the management of epidemic; there, I delve into the particular obedience they request and the obstacle that this is to inhabit a different care. Later, I will stop at what I call “virus pathologiza- tion”, exploring some of its features and the political effects it would bring, especially the building of securitized care. Finally, I will focus on the alliance between biopower and capital, which takes its best expression in the famous dilemma “economy or life”. That dilemma exposes that biopoliti- cal protection life is a “make produce” too.

Seed Health of Chickpea as Influenced by Different Packaging during Storage
Authors: Thakur Vijaysingh , Nawalagatti C. M. 
Published: September 2021

A storage experiment was conducted to know the influence of cloth, gunny, high density polythene (HDPE), and vacuum packed bags on the seed health of chickpea for 18 months. To investigate, chickpea seeds were packed in all the bags and were kept in ambient conditions. During the storage period, there was a lot of fluctuation in moisture content of the seeds based on the relative humidity in cloth, gunny, and HDPE bags due to the pervious nature of packaging materials whereas, there was no moisture fluctuation in vacuum packed bags due to lower water vapor and oxygen transmission rate and higher thickness of polythene bag used for vacuum package. After 8 months of storage period, there was bruchids infestation to the seeds stored in cloth, gunny, and HDPE bags whereas, no bruchids infestation were seen to vacuum packed bag even after 18 months of storage but germination, root length, shoot length, seedling vigour index, seedling dry weight has reduced and mean germination time, electrical conductivity of seed leachates has increased due to seed aging. Hence, vacuum packaging technology can be effectively used for storage of chickpea seeds for longer period without any aid of chemicals.

Lablab purpureus (L.) Synonym Dolichos lablab (L.) Sweet; is a minor and an important multipurpose legume. Despite this it classified as an orphaned crop hence few studies on its improvement have been undertaken. Limited studies have been carried out on use of mutation on dolichos improvement. Four elite Lablab genotypes coded G1, B1, M5 and W7 were mutagenized with two doses of gamma radiation 300Gy and 400 Gy with objective to study the effect of mutation on various agronomical traits at M2 generation. Data on effect of irradiation on lablab was collected 10 randomly selected plants of on each plot .The traits evaluated were leaf length, leaf width, number of raceme per plant, raceme length, pod length, pod width, plant height, dry seed yield per plant and seed length and seed width. For these traits mean of mutant plants was significantly different from mean of control plants at P≤0.05. Mutant accessions of B1, M5 and W7 genotypes exhibited wide mutation spectra after mutagenesis of albino, leafiness, upright single stem, seedless pod, short dwarf pod, variegated leaf, variation in flower colour, variation in growth habit, leaf shape, seed colour. Gamma irradiation doses of 300 Gy and 400 Gy were potent in mutagenesis of the studied dolichos lablab. The agronomically diverse mutants are an important resource for dolichos improvement through breeding and genetic studies. Mutants with variegated leafs and flower colour can be used in the landscaping while those different seed colour could be used in the improvement of sensory and cooking qualities of other native dolichos lablab beans.

ImportanceAcute pulmonary embolism (PE) is a major cause of morbidity and mortality in patients with cancer in the US and worldwide.ObjectivesTo assess the trends in PE-related mortality from 2011 to 2020 among US patients with cancer across age, sex, ethnic and racial groups, urbanicity, and regionality.Design, Setting, and ParticipantsThis cohort study used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research data system to determine national trends in age-adjusted mortality rates (AAMRs) due to acute PE among US patients with cancer aged 15 years or older from January 2011 to December 2020. Concomitant trends in cancer mortality and incidence that may have contributed to PE-related mortality were obtained from US Cancer Statistics. Data were analyzed from September to November 2024.ExposurePE-related mortality.Main Outcomes and MeasuresThe primary outcome was PE-related deaths among individuals with cancer. AAMRs and cancer incidence were assessed using joinpoint regression modeling, expressed as an average annual percentage change (AAPC) with relative 95% CIs.ResultsFrom 2011 to 2020, a total of 27 280 194 individuals aged 15 years or older (13 897 519 male [50.9%]; 13 382 675 female [49.1%]) died in the US. The AAMR for PE-related mortality in patients with cancer increased during this time period (AAPC, 2.5%; 95% CI, 1.4% to 3.6%; P = .001), without differences between sexes (P for parallelism = .38). The AAMR increased among those aged 15 to 64 years (AAPC, 3.2%; 95% CI, 1.9% to 4.6%; P = .001), non-Hispanic and non-Latinx White individuals (AAPC, 2.7%; 95% CI, 1.52% to 3.94%; P = .001), non-Hispanic and non-Latinx Black or African American individuals (AAPC, 2.2%; 95% CI, 0.7% to 3.7%; P = .001), Hispanic and Latinx individuals (AAPC, 2.6%; 95% CI, 0.7% to 4.5%; P = .006), and among individuals residing in the Southern US (AAPC, 3.7%; 95% CI, 1.3% to 6.2%; P = .003). During the same period, age-adjusted cancer incidence and cancer-related mortality decreased while the absolute number of new cancer diagnoses and cancer-related deaths increased.Conclusions and RelevanceThis cohort study found that despite decreases in cancer-related mortality rates, age-adjusted PE-related mortality in US patients with cancer increased over the last decade; concerning trends included rising PE-related mortality in younger individuals aged 15 to 64 years, particular ethnic and racial groups, and the Southern region of the US. Recognition of such patterns may inform further research into thromboprophylaxis and treatment of PE as a complication of cancer and cancer-directed therapy.

AbstractMaterial sustainability requires energy‐efficient and rapid strengthening processes. In alloys, strengthening through diffusion‐driven precipitation is limited by the low vacancy concentration, with fewer than one vacancy per 100 billion lattice sites at room temperature in metals such as aluminum and iron under thermodynamic equilibrium. Artificially increasing vacancy concentrations by 1 to 7 orders of magnitude above equilibrium levels through quenching, irradiation, or deformation can significantly accelerate material strengthening. However, measuring vacancy concentrations below 10−7 in alloys and achieving spatial mapping remain challenging. Here, a vacancy‐mediated gradient microstructure near grain boundaries is reported and analyzed to investigate diffusion enhancement and the local vacancy population in an Al‐Zn system. This method uses cryogenic processes to preserve excess vacancies and halt microstructure evolution, enabling intermittent measurement of compositional fluctuations during ultrafast spinodal decomposition. It allows for the assessment of diffusion enhancement and determination of vacancy supersaturation in sub‐micrometer regions. Liquid nitrogen–quenched Al–12.5 at.% Zn alloy shows a vacancy concentration of ≈10−7 at room temperature, dropping to 10−9 after 3 h, with significant spatial variation near grain boundaries. This work addresses gaps in understanding the evolution and distribution of vacancies across various measurement scales, advancing the control of vacancies to enhance the strengthening of engineering alloys.

AbstractPancreatic ductal adenocarcinoma (PDAC) is a devastating disease, necessitating approaches to improve prognosis. As the mediator of allergic process, mast cells have been found in various cancers and are associated with survival. However, the biological behaviors of tumor‐associated mast cells (TAMCs) remain unclear. Herein, an excessive infiltration of TAMCs in PDAC is demonstrated, which apparently associated with poor survival in PDAC patients. PDAC cells are found to recruit CXCR2+ MCs into TME, and then inhibited MCs ferroptosis, and maintained their proliferation. Concomitantly, the tumor‐derived exosome miR‐188‐5p activated the PTEN/AKT/GSK3β signaling, further stabilized transcriptional factor ERG by inhibiting its ubiquitin degradation, and finally enhanced the transcription of cxcl10 within TAMCs. In reverse, TAMCs‐derived CXCL10 reversely promoted tumor epithelial‐mesenchymal transition and induced immunosuppressive tumor microenvironment by recruiting CXCR3+ Tregs. Sodium cromoglycate (SCG) is a membrane stabilizer for MCs and confirmed as an effective and widely used agent to block TAMCs‐derived CXCL10 and further sensitize the therapeutic efficacy of anti‐PD‐1 antibody plus gemcitabine for PDAC. These findings illuminate a critical and innovative crosstalk between TAMCs and PDAC cells that promote PDAC progression, and SCG sensitizes PDAC to the current immuno‐chemotherapy, which reveals its potential to be a valuable adjuvant for PDAC patients.

AbstractThe efficacy of in situ cancer vaccines (ISCVs) is hindered by the poor immunogenicity of tumor cells. Here, PRIZE, a P53‐repair nanosystem based on a virus‐mimicking nanostructure to deliver p53 mRNA and Zn (II) into tumor cells, domesticating tumor cells by restoring intracellular P53 levels to bolster their immunogenicity, is designed. PRIZE ensures precise delivery to tumor sites, stabilizes p53 mRNA with its biomineralized structure, and extends the half‐life of P53. This research highlights that PRIZE can efficiently repair P53 abnormalities in 4T1 (P53‐deficient) and MC38 (P53‐mutant) cells, subsequently upregulating the expression of major histocompatibility complex (MHC) class I molecules and the surface co‐stimulatory molecule CD80 on tumor cells, enhancing antigen presentation and transforming tumor cells into in situ antigen reservoirs. The co‐delivered photothermal agent (ICG) can trigger immunogenic cell death under laser irradiation, effectively releasing tumor‐associated antigens, and inducing the formation of ISCVs. Importantly, in P53 abnormal tumor mouse models, the induced ISCVs initiate the cancer immune cycle (CIC), demonstrating outstanding tumoricidal immunity and effectively thwarting tumor metastasis and postoperative recurrence, which provides valuable insights for advancing personalized cancer immunotherapy.
Quantum Chemical Understanding of the O2 Release Process from Nature's Water Splitting Cofactor
Authors: Guo Yu , Kloo Lars , Sun Licheng 
Published: February 2025

AbstractNatural photosynthesis plays a vital role in the supply of energy and oxygen necessary for the survival of biological organisms. The current leading proposal of the O−O bond formation in photosystem II suggests the coupling between the central μ‐oxo (O5) and the additional oxygenic ligand (Ox) of the manganese‐calcium oxide cofactor. However, the subsequent process through which molecular dioxygen is formed and released remains elusive. In this report, quantum chemical calculations reveal that the O2 release process is initiated by the cleavage of the Mn−O5 bond, without a preliminary conformational change of the peroxide [O5‐Ox]2− group. Subsequently, the [O5‐Ox] moiety is converted from the superoxide to the weakly bound quasi‐O2 where the Mn−Ox bond is cleaved, and after a twist of the quasi‐O2 unit, the free O2 is ultimately released. Alternative pathways display significantly slower kinetics, due to the lower structural stabilities of the rate‐limiting transition states. The cause of the difference is associated with the Jahn‐Teller axial orientation and the local ring strain within the Mn cluster. These findings contribute to unravelling the intricate mechanism involved in an important step of photosynthetic oxygen evolution for a deeper understanding of nature's water oxidation catalysis.

ABSTRACTScabies is common in the Democratic Republic of Congo, often underestimated, including in infants. In this report, a 4‐month‐old's irritability, nocturnal itching, insomnia, and skin rashes raised suspicion, confirmed by parasitological examination. The father's lack of infestation despite sharing the bed with the infant and his mother poses a question.
