Tierra en movimiento (2014) de Tiziana Panizza. Materialidad, memoria y supervivencia
Authors: De los Ríos Valeria 
Published: January 2018

El documental Tierra en movimiento (2014) es un ensayo audiovisual realizado en colaboración con el poeta chileno Germán Carrasco. En él el contrapunto de los sonidos, textos y narraciones over (en otras palabras, su condición intermedial), permite establecer una reflexión poética sobre la experiencia material y concreta de vivir en un territorio devastado por un sismo. Los restos de aquello que sobrevivió se recompone para hablar de la memoria y del presente, oponiéndose al mismo tiempo a la monumentalidad del recuerdo y a la razón neoliberal.

Objectives To assess the prevalence and types of arrhythmias in Saudi OSA patients and to identify predictors of arrhythmia in this group of patients.
METHODS This case-control study included all patients who underwent level I attended overnight polysomnography between 2009 and 2012. Electrocardiographic data collected during sleep studies of patients with and without OSA were manually reviewed.
Results The study comprised 498 patients (394 OSA patients and 104 non-OSA patients (controls). The prevalence of arrhythmia in OSA patients was higher than that in the controls (26.9% vs. 11.5%; p=0.001). Comparing OSA patients and controls showed: premature atrial contraction (10.2%vs.2.9%;p=0.019), premature ventricular contraction (PVC) (19.3%vs.9.6%;p=0.02), non-isolated PVC (bi/tri/qua) 10.8%vs.2.3%;p=0.04) and atrial fibrillation (1.6%vs.0%;p=0.001). Multiple logistic regression analysis revealed that, patients with OSA had twice the odds of having any cardiac arrhythmia (OR 1.91; CI 95% 1.27-3.11; p <0.05).
Conclusions Patients with OSA had a higher prevalence of arrhythmia compared to controls, and OSA is a predictor of arrhythmia during sleep.

Introduction The purpose of this paper was to evaluate and compare the questionnaires regarding sleep quality among children aged up to 12 years old, used in the Portuguese language in Brazil.
Material and methods A search at the literature databases of Lilacs, Scielo and Pubmed was performed using keywords “sleep quality” and “children”. Selected Articles were analysed for age of the studied population, the number of questions and the issues addressed thereby, who realized the application, the analysis of the results, and content.
Results Out of 9377 titles, 11 studies were included, performing 7 different questionnaires: Questionnaire to measure quality of life among children with enlarged palatine and pharyngeal tonsils (translation of OSD-6) (1); Inventory of Sleep Habits for Preschool Children (2); the Questionnaire on Obstructive Sleep Apnoea-18 (OSA-18) (3), Sleep Questionnaire by Reimão and Lefévre - QRL (4); the Questionnaire on Sleep Behaviour Patterns (5) and the translation of the Sleep Disturbance Scale for Children (6); Brief Infant Sleep Questionnaire - BISQ (7) . Six of the questionnaires have covered the following issues: snoring and daytime sleepiness.
Conclusions A total of 7 protocols were found to be available in Brazil, the most commonly mentioned being OSA-18 and OSD-6. The use of protocols as a guided interview helps to define diagnosis and treatment among the paediatric population, but its large variability makes it difficult to compare a standardised monitoring process.

AbstractBilayer 3D/2D heterojunction perovskite solar cells (PSCs) have attracted increasing interest due to great advantages of high power conversion efficiency (PCE) and ultrastability. Previous studies are mostly focused on addressing the issue of poor charge transport originated from the spacer cations or random phase distribution of 2D perovskite in 3D/2D heterojunction. However, the carrier recombination at the surface of 2D layer is often ignored. Herein, a novel strategy of passivating 2D perovskite in 3D/2D heterojunction with a thin surface termination layer (STL) is proposed. It demonstrates that surface defects of 2D perovskite are terminated by the molecule of 2‐amino‐5‐mercapto‐1,3,4‐thiadiazole through multi‐site interaction, leading to the significant suppression of non‐radiative recombination and considerable improvement of hole transport with the well‐aligned energy band simultaneously. As a result, the PSCs with the constructed 3D/2D/STL structure processed in air have achieved a champion PCE of 25.09% with high open‐circuit voltage of 1.211 V (the voltage deficient of 0.349 V). The unencapsulated devices retain exceeding 90% of the initial PCE after storing in air for 1008 h or under illumination in N2 for 504 h. This work opens up an important, but unnoticed topic of defect passivation of 2D perovskite for 3D/2D heterojunction PSCs.

Published: October 2024

AbstractElectrospun nonwovens are highly versatile materials. Significant progress is achieved in terms of materials, methods, and setups, enabling a wide range of applications. However, regio‐selective surface modification of electrospun fibers along their longitudinal axes remains an open challenge. This paper addresses this challenge and presents side‐by‐side electrospinning as a straightforward method for producing functional bead‐on‐string (BOS) fibers. The functional beads carry tertiary amino groups as a platform for further modifications. The beads are arranged in recurring distances along the fiber, allowing a precise fiber modification on the micron scale. This arrangement has been used for modifications with a fluorescent dye and gold nanoparticles (AuNP) in a highly precise and regio‐selective manner. AuNP decorated BOS fiber nonwovens show excellent performance as heterogenous catalysts under flow conditions demonstrating low pressure drop, high turnover frequency, and recyclability.

AbstractMelt electrowriting (MEW) is a high‐resolution additive manufacturing technology capable of depositing micrometric fibers onto a moving collector to form 3D scaffolds of controlled mechanical properties. While the critical role of layer bonding to achieve mechanical integrity in fused deposition modeling has been widely reported, it remains largely unknown in MEW, in part due to a lack of methods to assess it. Here, a systematic framework is developed to unravel the significance of layer bonding in MEW scaffolds and its ultimate effect on their mechanical properties. Results show that printing parameters, scaffold design, and print path have a strong impact on layer bonding strength of poly(ɛ‐caprolactone) MEW scaffolds. This study demonstrates that a small increase of 5 µm in fiber diameter can enhance the layer bonding strength by as much as 70%, greatly impacting the overall scaffold properties. A method is also established to control MEW scaffold layer bonding using a heated collector. Importantly, this study reveals that scaffold architecture alone is not responsible for the overall mechanical properties. Finally, a method to obtain tailored layer bond strengths within a given scaffold is established. This has significant implications as provides new possibilities to control mechanical properties of MEW scaffolds through layer bonding.

AbstractFerrimagnetic materials with antiparallel exchange coupling, exhibit spin‐orbit‐torque‐induced dynamics, offering an emerging platform for realizing neuromorphic devices, such as artificial synapses. However, the state‐of‐the‐art artificial synapses based on ferrimagnet suffer from poor analog switching linearity, which serves as a bottleneck for achieving complex tasks with high accuracy in neuromorphic computing. Here, an artificial synapse is reported with high‐weight update linearity in a compensated ferrimagnetic crossbar device. In particular, the linear weight update of the synapses is enhanced by engineering the current density distribution. Using experimentally derived device parameters, handwritten digit recognition can be achieved with an accuracy of over 95% in a three‐layer fully connected artificial neural network. The work provides a universal method to improve the synaptic linearity, which also paves the way for applying the spin‐orbit device in neuromorphic computing.

AbstractBackgroundChronic rhinosinusitis with nasal polyposis (CRSwNP) is associated with a high rate of disease recurrence following endoscopic sinus surgery (ESS). Type 2 disease is associated with a higher incidence of recurrence and is believed to impact disease resolution via interference with epithelial healing and pathogen immunity. We wished to verify if perioperative control of Type 2 inflammation with an anti‐IL4/IL13 targeting monoclonal antibody and during the resolution period following surgery leads to better control of the disease long term.MethodsIn this prospective, placebo‐controlled, double‐blinded trial. Thirty adult subjects with recurrent CRSwNP underwent ESS plus or minus 14 weeks of perioperative dupilumab, initiated 4 weeks (two injections) pre‐ESS. Subjective and objective parameters of nasal patency, olfaction, quality of life (QoL), and adverse events were monitored up to 52 weeks post‐ESS. Microbiological culture was performed to characterize pathogens colonization under both conditions.ResultsESS safely improved subjective and objective measures of nasal patency, olfaction, and QoL in both groups. Olfaction was conserved longer in the dupilumab‐treated group, with 33.3% of subjects presenting anosmia at 12 months after ESS in the dupilumab group compared to 50.0% with placebo. This was associated with persistent decreases in serum IgE, which were not seen with placebo treatment. No unusual safety signals were observed.ConclusionShort‐course adjuvant perioperative treatment with dupilumab is associated with improved long‐term olfactory outcomes and persistent lowering of serum IgE.
The Young Einstein in Italy and the Annalen der Physik
Authors: Bracco Christian 
Published: October 2024

AbstractWith the help of the Annalen der Physik, we can trace the young Einstein's footsteps in Italy in various ways: the interest in the topic of his first article on capillarity probably dates back to an earlier meeting with Carlo Marangoni in Casteggio; Einstein's reading of articles by Paul Drude and Wilhelm Wien allow us to identify the library of the Lombard Institute, Milan's Academy of Sciences and Letters, where the young man is working on his bibliography; this bibliography provides elements for a better understanding of the turnaround of his thesis, in mid‐April 1901, on molecular forces in gases; and finally we see Einstein use his papers in the Annalen in his search for university posts, in connection with Giuseppe Jung, Michele Besso's uncle.

Published: October 2024

AbstractWechselwirkungen von Kohlenstoff‐Nanopartikeln mit Gasen sind von zentraler Bedeutung in vielen Umwelt‐ und Technik‐Prozessen, jedoch sind die zugrundeliegenden Reaktionskinetiken und ‐mechanismen nicht ausreichend gut verstanden. Hier untersuchen wir die Oxidation und Gasifizierung von Kohlenstoff‐Nanopartikeln durch NO2 und O2 unter Verbrennungsabgasbedingungen. Mit Hilfe eines umfassenden experimentellen Datensatzes und einem kinetischen Mehrschichtmodell (KM‐GAP‐CARBON), werden die Aufnahme und Freisetzung von Gasmolekülen sowie die zeitliche Entwicklung der Partikelgröße und Oberflächenzusammensetzung verfolgt. Die experimentellen Ergebnisse werden durch einen Modellmechanismus beschrieben, der verschiedene Arten von Kohlenstoffatomen (rand‐ und basalflächenartig) und die Bildung eines reaktiven Sauerstoff‐Intermediats (aktivierter CO‐Komplex) als geschwindigkeitsbestimmenden Schritt umfasst. Ein Übergang zwischen unterschiedlichen chemischen Regimen, welche bei niedrigeren Temperaturen durch die Reaktivität von NO2 und bei höheren Temperaturen durch die Reaktivität von O2 bestimmt sind, spiegelt sich in einem Anstieg der beobachtbaren Aktivierungsenergie von ~60 kJ/mol auf ~130 kJ/mol wider. Wir leiten Energieprofile für drei alternative Reaktionspfade ab, die die uni‐ oder bimolekulare Zersetzung von reaktiven Sauerstoff‐Intermediaten beinhalten.

Published: October 2024

AbstractOptical regulation of transcription using chemical compounds is an effective strategy to manipulate gene expression spatiotemporally. Conventional caging approaches with photoremovable protecting groups may require intense UV‐light exposure and release potentially toxic byproducts. To address these problems, here we developed a light‐mediated transcriptional regulation system by combining a caging‐group‐free photoactivatable dye PaX560 and a multidrug‐binding transcriptional regulator QacR. The cationic dye generated from PaX560 through traceless photoconversion bound QacR and reduced its repressor function, resulting in transcriptional activation. Importantly, this system allowed transcriptional activation with a large dynamic range under mild visible light exposure and simultaneous detection of the state of the photoactivated effector. This module was integrated into the T7 RNA polymerase expression system to demonstrate light‐activated transcription in vitro and in living cells.

AbstractThe development of efficient catalytic materials in the energy field could promote the structural transformation from traditional fossil fuels to sustainable energy. In heterogeneous catalytic reactions, ligand modification is an effective way to regulate both electronic and steric structures of catalytic sites, thus paving a prospective avenue to design the interfacial structures of heterogeneous catalysts for energy conversion. Although great achievements have been obtained for the study and applications of heterogeneous ligand‐modified catalysts, the systematical refinements of ligand modification strategies are still lacking. Here, we reviewed the ligand modification strategy from both the mechanistic and applicable scenarios by focusing on heterogeneous electrocatalysis. We elucidated the ligand‐modified catalysts in detail from the perspectives of basic concepts, preparation, regulation of physicochemical properties of catalytic sites, and applications in different electrocatalysis. Notably, we bridged the electrocatalytic performance with the electronic/steric effects induced by ligand modification to gain intrinsic structure‐performance relations. We also discussed the challenges and future perspectives of ligand modification strategies in heterogeneous catalysis.

Published: October 2024

AbstractSphingoid bases are important bioactive lipids found in a variety of organisms, serving as the backbone of sphingolipids, which regulate essential physiological processes. Here we describe the total synthesis and structure revision of halisphingosine A, a sphingoid base initially isolated from marine sponges. To address inconsistencies in the NMR interpretation of this natural product, we developed a synthetic route involving a late‐stage enantioselective Henry reaction that allows access to multiple stereoisomers of the proposed halisphingosine A core structure. Our library of 32 fully characterized synthetic stereoisomers enabled us to rectify the structure of halisphingosine A as (2R,3R,8R,Z)‐2‐aminooctadec‐9‐ene‐1,3,8‐triol, and to pursue further structure–activity relation (SAR) studies regarding their antimicrobial and cytotoxic potential. In summary, our study offers a yet unreported compound library along with validated analytical datasets of marine sphingoid base derivatives, which significantly affects future ecometabolomic marine research and will facilitate the identification of inhibitors of sphingolipid metabolism or antagonists of sphingolipid base‐sensing receptors.

Published: October 2024

AbstractThe widespread integration of ZnO nanoparticles (NPs) as the electron transport layer has yielded significant advancements in the performance of hybrid quantum dot light‐emitting diodes (QLEDs). It has been widely demonstrated that conventional hybrid QLEDs exhibit a positive ageing effect, which refers to the markedly increased whole performance of QLEDs with prolonged annealing, voltage stressing, or storage time. This phenomenon is believed to be closely associated with the ZnO (or its derivative such as ZnMgO) electron transport layer. This review aims to summarize the role of ZnO in positive ageing and to discuss the existing challenges in the hybrid QLEDs. Currently, the origins of the positive ageing can be categorized into two types: i) interface effect between ZnO and metal cathode and ii) passivation effect of ZnO NPs. Then the underlying mechanisms for positive ageing are discussed in detail and their limitations are pointed out. Finally, a perspective and outlook for the positive ageing effect are shown, as well as a suggestion for the future research directions and opportunities of hybrid QLEDs.

ABSTRACTBackgroundApproximately one‐third of US adults have a tattoo, and the prevalence is increasing. Tattooing can result in long‐term exposure to carcinogens and inflammatory and immune responses.MethodsWe examined tattooing and risk of hematologic cancers in a population‐based case–control study with 820 cases diagnosed 2019–2021 and 8200 frequency‐matched controls, ages 18–79 years. We calculated odds ratios (OR) and 95% confidence intervals (CI) using multivariable‐adjusted logistic regression models.ResultsThe prevalence of tattooing was 22% among Hodgkin lymphoma (HL) cases, 11% among non‐Hodgkin lymphoma (NHL) cases, 16% among myeloid neoplasm cases, and 15% among controls. Though there were no clear patterns of associations between ever receiving a tattoo and risk of HL, NHL, or myeloid neoplasms overall, in analyses restricted to ages 20–60 years, ever receiving a tattoo (OR 2.06 [95% CI 1.01, 4.20]) and receiving a tattoo 10+ years prior (OR 2.64 [95% CI 1.23, 5.68]) were associated with an aggregated group of rarer mature B‐cell NHLs. We also observed elevated risks for a 10+ year latency for myelodysplastic syndromes and chronic myeloid leukemia (OR 1.48 [95% CI 0.40, 5.41], and OR 1.24 [95% CI 0.45, 3.43], respectively).ConclusionsThough estimates were imprecise, we found some suggestive evidence that tattooing may be associated with an increased risk of certain hematologic cancer subtypes. With an estimated 46% prevalence of tattooing in US individuals ages 30–49, additional studies are needed to understand the degree to which these exposures may be associated with hematologic cancer risk.

ABSTRACTBackgroundEmerging evidence has indicated possible efficacy benefit of platinum‐based chemotherapy as neoadjuvant treatment for invasive ductal carcinoma triple‐negative breast cancer (TNBC). However, it has not been endorsed by current guidelines due to highly controversial results.Materials and MethodsPresent study aims to investigate predictive and prognostic roles concerning single nucleotide polymorphisms (SNPs) in XRCC1 and BRCA1, BRCA2 genes for early stage TNBC patients that received platinum‐based neoadjuvant treatment. We prospectively enrolled women with stage IIB‐IIIB TNBC that had progressed on neoadjuvant taxane and anthracycline‐based chemotherapy at Xinjiang Medical University Affiliated Cancer Hospital. Tumor response and pathological complete response (pCR) rate were assessed. Invasive disease‐free survival (iDFS) and overall survival (OS) were analyzed. Patients' blood samples were subject to Sanger sequencing to genotype XRCC1 Arg194Trp and Arg399Gln, BRCA1 s1799949, and BRCA2 rs206115. Univariate and multivariate logistic regressions were employed to investigate associations between SNPs and clinical characteristics with treatment response and pCR. A total of 45 patients were enrolled.ResultsThe cohort showcased ORR of 44.4%, pCR of 28.9%, median iDFS of 22 months, and a 3‐year OS of 73.3%. The A/G and G/G genotypes of BRCA1 rs1799949, and the T/T genotype of BRCA2 rs206115 were associated with higher responsive rate. Histologic grade of III and Ki67 expression > 65% were associated with low responsive rate. Moreover, the A/G genotype of BRCA1 rs1799949 and T/T genotype of BRCA2 rs206115 correlated to high pCR. The histologic III and T4 stage correlated to inferior iDFS. Carrier of BRCA1 rs1799949 G/G had the most favorable OS, carriers of A/A showed the poorest OS, and those with A/G genotype showed an intermediate OS.ConclusionsPlatinum‐based chemotherapy might serve as a therapeutic option for TNBC patients who were resistant to anthracycline‐ and taxane‐based neoadjuvant therapy. Our study identified several genetic and clinical features that might function as prognostic and predictive markers.
