Abstract
In this research, a new generation of ternary nanocomposites based on poly(ethylene terephthalate) (PET), phosphorylated chitosan and surface modified alumina nanoparticles were fabricated in four steps. The phosphorylation process was targeted for the insertion of elemental phosphorus as a flame retardant agent in the final PET nanocomposite. Likewise, environmentally friendly nano-alumina was used for PET matrix to improve the flame retardant properties of PET in collaboration with elemental phosphorus. Alternatively, the presence of alumina nanoparticles in combination with phosphorylated chitosan improved the antibacterial activity of the PET matrix. Furthermore, the effects of the phosphorylated chitosan and alumina nanoparticles on the morphology and thermal properties of nanocomposites were inspected by different approaches. The structure and distribution of the nanoscale particles in PET were analyzed by scanning electron microscopy. In addition, differential scanning calorimetry and thermogravimetric analyses were used for the in-depth evaluation of the thermal properties of prepared nanocomposites.

Abstract
Background: Ferroptosis is a newly identified form of regulated cell death (RCD) characterized by the iron-dependent lipid reactive oxygen species (ROS) accumulation, but its exact mechanism in gliomas remains elusive. Acyl–coenzyme A (CoA) synthetase long-chain family member 4 (Acsl4), a pivotal enzyme in the regulation of lipid biosynthesis, has been found to benefit the initiation of ferroptosis, but its role in gliomas likewise needs clarification. Erastin, widely investigated as an inducer of ferroptosis, was recently found to regulate lipid peroxidation by regulating Acsl4 other than glutathione peroxidase 4 (GPX4) in ferroptosis. Methods: Relationship between Hsp90, Drp1 and Acsl4 was determined by Co-immunoprecipitation/ Mass spectrometry and western blot assay. The impact of Hsp90 and Drp1 on Acsl4-dependent ferroptosis was examined by lipid peroxidation indicators in patient-derived PL1 and PG7 cells. The morphological changes of mitochondria are observed by confocal-fluorescence microscopy and transmission electron microscope. Therapeutic efficacy of Erastin-induced ferroptosis in vivo was examined in xenograft mouse models.Results: In this study, we demonstrated that heat shock protein 90 (Hsp90) and dynamin-related protein 1 (Drp1) actively regulated Acsl4 expression in erastin-induced ferroptosis in gliomas. Hsp90 overexpression and calcineurin (CN)–mediated Drp1 dephosphorylation at serine 637 (Ser637) promoted ferroptosis by altering mitochondrial morphology and increasing Acsl4-mediated lipid peroxidation. Importantly, the Hsp90–Acsl4 pathway mediated Acsl4-dependent ferroptosis, amplifying the anticancer activity of erastin in vitro and in vivo. Conclusions: Our study not only uncovered an important role of Hsp90–Drp1–Acsl4 pathway in erastin-induced ferroptosis but also reveals an efficient mechanism of Acsl4 as a potential therapeutic target to ferroptosis-mediated glioma therapy.

Abstract
Heralded entanglement between distant quantum memories is the key resource for quantum networks. Based on quantum repeater protocols, these networks will facilitate efficient large-scale quantum communication and distributed quantum computing. However, despite vast efforts, long-distance fibre based network links have not been realized yet. Here we present results demonstrating heralded entanglement between two independent, remote single-atom quantum memories generated over fibre links with a total length up to 33 km. To overcome the attenuation losses in the long optical fibres of photons initially emitted by the Rubidium quantum memories, we employ polarization-preserving quantum frequency conversion to the low loss telecom band. The presented work represents a milestone towards the realization of efficient quantum network links.
Evaluation of the mechanical anisotropy of lacustrine smectite clays by triaxial test analysis
Authors: Jiménez-Camargo Jubier Alonso , Carreon-Freyre Dora 
Published: January 2022

Abstract
This paper describes the role of fabric anisotropy during clayey soil deformation. A set of triaxial tests was performed on vertical and horizontal specimens of undisturbed smectite lake sediments from Jurica, Queretaro in Mexico. The results allowed to analyze the influence of bedding and discontinuities on the mechanical behavior of Jurica clays after failure. Tests with applied low strain rates allowed pore pressure equalization within specimens with different gravimetric water content and degree of saturation. Shear failure results of undrained tests showed that deformation distributes differently in both horizontal and vertical directions and that stress may be dissipated by pore collapses, fractures and particle deformation. The experimental evidence suggests that microfabric is a relevant variable in the overall mechanical response of clayey sediments that depends on the natural fabric (bedding and discontinuities), mineralogy, and water content. A detailed analysis of Young´s Moduli (E) showed the high variability of this parameter from 108 to 409 kg/cm2 (calculated at 30% of σdmax) and its dependence on the orientation of the specimen and the water content. In addition, p’-q’ graphs illustrate the relevance of considering mechanical anisotropy in clays and provide further insights to understand the role of smectites in progressive shear deformation.

Published: January 2022

Abstract
Bisphenol A (BPA) is one of the typical environmental endocrine disruptors. BPA was leached from polycarbonate containers into food and water, and it has been detected in collective samples from humans. Microtubule-associated protein 2 (MAP2) and Tau maintain microtubule normal function and promote the normal development of the nervous system. Synaptophysin (SYP) and drebrin (Dbn) proteins are involved in regulating synaptic plasticity. This study aimed to determine the adverse effects of BPA on Neuro-2a cells by investigating the synaptic and cytoskeletal damage. Cells were exposed to 0 (Minimum Essential Medium, MEM), 0.01% (v/v) DMSO and 150 µM BPA for 12, 24, or 36 h. Morphological analysis revealed that the cells in the BPA-treated groups shrank, collapsed, and had a reduced number of synapses compared with those in the control groups. CCK-8 and LDH assays showed that the mortality of Neuro-2a cells increased as the BPA treatment time was prolonged. Transmission electron microscopic analysis further revealed that cells demonstrated nucleolar swelling and nuclear membrane and partial mitochondrial dissolution or condensation following BPA exposure. BPA also significantly decreased the relative protein expression levels of MAP2, Tau, and Dbn (P < 0.01). Interestingly, the relative protein expression levels of SYP increased (P < 0.01). These results indicated that BPA damaged the development and proliferation of Neuro-2a cells by disrupting cytoskeleton and synaptic integrity.

Published: January 2022

Abstract
Temperature and strain are two vital parameters that play a significant role in wound diagnosis and healing. As periodic temperature measurements with a custom thermometer or strain measurements with conventional metallic gauges became less feasible for the modern competent health monitoring, individual temperature and strain measurement modalities incorporated into wearables and patches were developed. The proposed research in the article shows the development of a single sensor solution which can simultaneously measure both the above mentioned parameters. This work integrates a thermoelectric principle based temperature measurement approach into wearables, ensuring flexibility and bendability properties without affecting its thermo-generated voltage. The modified thermoelectric material helped to achieve stretchability of the sensor, thanks to its superior mechano-transduction properties. Moreover, the stretch-induced resistance changes become an additional marker for strain measurements so that both the parameters can be measured with the same sensor. Due to the independent measurement parameters (open circuit voltage and sensor resistance ), the sensing model is greatly attractive for measurements without cross-sensitivity. The highly resilient temperature and strain sensor show excellent linearity, repeatability and good sensitivity. Besides, due to the compatibility of the fabrication scheme to low temperature processing of the flexible materials and to mass volume production, printed fabrication methodologies were adopted to realize the sensor. This promises low cost production and a disposable nature (single use) of the sensor patch. The temperature-strain dual parameter semi-transparent sensor has been further tested on mice wounds in vivo. The preliminary experiments on mice wounds offer prospects for developing smart, i.e. sensorized, wound dressings for clinical applications.

Published: January 2022

Abstract
Background
Facial appearance and expressions influence social interaction. However, few studies have reported on the stigma associated with spasms from facial dystonia. This study investigated the stigma and quality of life for these patients.
Methods
This cross-sectional study included 90 patients with facial dystonia (hemifacial spasm [HFS], blepharospasm [BSP], and blepharospasm-oromandibular dystonia [BOD]; 30 patients per group) and 30 individuals without dystonia (control group) from October 2019 to November 2020. All participants underwent stigma, quality of life, and mental health evaluations using seven questions related to stigma, the 36-item Short Form Health Survey, the 14-item version of the Hamilton Anxiety Scale (HAMA), and the 24-item version of the Hamilton Depression Scale.
Results
Nineteen patients (21.11%) felt stigmatized. Patients with BPS and HFS had more difficulty finding a job and were more susceptible to discrimination than healthy individuals. The role-physical and social function scores were significantly lower in the dystonia groups than in the control group. The vitality score of the BPS group and the mental health scores in the BPS and BOD groups were significantly less than those of the control group. The HAMA scores in the BPS and BOD groups were significantly higher than in the control group. Regression analysis demonstrated that the disease course influenced depression.
Conclusion
Enacted stigma from a negative public attitude may be the main factor triggering stigma in patients with facial dystonia, with detrimental effects on psychosocial outcomes, including social rights, quality of life, and mood.

Published: January 2022

Abstract
Background: While suicide among adolescents has emerged as a significant social problem, few studies have examined the relationship between changes in suicide methods and suicide success following multiple attempts. This study aimed to investigate the relationship between changing suicide methods and successful suicide among adolescents after repeated attempts.Methods: This retrospective study analyzed the psychiatric history of patients (n=227) between 10 and 18 years of age who visited a pediatric emergency center between January 2007 and February 2021 for suicide attempts. Results: Out of a total of 227 patients, 80 achieved successful suicide attempts, including emergency hospitalization or death. A significant association was observed between successful suicide in patients with multiple attempts who chose drug intoxication (DI) as the index method (p=0.010) and patients with multiple attempts who chose DI as a suicide method (p=0.001). No statistically significant outcomes for changing methods and number of suicide attempts were evident.Conclusions: This study emphasizes the importance of identifying index methods as well as suicide methods among adolescent patients with multiple suicide attempts. This study identified predictors affecting the successful suicide of adolescents. Identifying the index method and the changed method among adolescent patients with multiple suicide attempts are significant predictors of successful suicide. Identifying the index method and changed method of suicide is expected to help in interviewing adolescents with multiple suicide attempts.
Avoiding dead ends: the experimental evolution of constraint as adaptation to environmental variation in Saccharomyces cerevisiae
Authors: Raghu Shravan , Smith Myron , Simons Andrew 
Published: January 2022

Abstract
Environmental unpredictability results in the evolution of bet-hedging traits, which maximize long-term fitness but are, by definition, suboptimal over short time scales. However, because suboptimal traits are expected to be purged by selection in the shorter term, the persistence of bet hedging remains perplexing. Here, we test the hypothesis that bet hedging persists through the evolution of constraint on short-term adaptation. We experimentally evolve Saccharomyces cerevisiae across two sequential treatments in which the frequency of extreme heat shocks decreases. We predict that experimental evolution under lower frequency heat shocks will result in greater adaptive constraint, or “purge-resistant” bet hedging. Constraint is assayed as evolutionary persistence of heat shock tolerance (HST) under constant benign conditions. As predicted, we find the retention of HST only in lines evolved under reduced frequency detrimental conditions. Results help explain the evolution of bet hedging, and challenge the traditional view that evolutionary constraint is inherently maladaptive.

Published: January 2022

Abstract
Developing high-power battery chemistry is an urgent task to buffer fluctuating renewable energies and achieve a sustainable and flexible power supply. Owing to the small size of proton and its ultrahigh mobility in water via the Grotthuss mechanism, aqueous proton batteries are an attractive candidate for high-power energy storage devices. Although Grotthuss proton transfer usually occurs in hydrogen-bonded networks of water molecules, in this work, we discover anhydrous Grotthuss-type proton transport in a dense oxide-ion array of solid α-MoO3 even without structural water. The fast proton transfer and accumulation that occurs during (de)intercalation in α-MoO3 is unveiled using both experiments and first-principles calculations. Coupled with a zinc anode and a superconcentrated dual-ion Zn2+/H+ electrolyte, the solid-state anhydrous Grotthuss proton transport mechanism realizes an aqueous MoO3-Zn battery with both high energy and power densities.
