BaZrO3 is known to be one of the very few perovskites that retains its ideal centrosymmetric Pm3¯m structure down to 2 K, despite showing intense Raman modes over the entire temperature range. Arguably, the Raman signals are either due to localized octahedral tilts/phase transition or due to second-order Raman-active phonon modes. By combining ab initio atomistic thermodynamics within the framework of density functional theory and experimental observations, we show that local disorder mediated by charged oxygen vacancy lifts this inherent cubic symmetry. The vacancies become more stable at real growth conditions viz. higher temperatures and lower oxygen partial pressures and a pseudo a0a0c− tetragonal-type structure develops in the short-range vicinity. However, the average long-range structure of BaZrO3, as determined by Bragg's diffraction, remains cubic. The defect states manifest as a shallow donor level below the conduction band minima in the electronic density of states and are responsible for a secondary transition at ≈3.86 eV in the UV-vis spectra. Our O 1s x-ray photoelectron spectra and radial distribution function analysis from extended x-ray absorption fine-structure, further validate the presence of stable anion vacancies in this perovskite. Thus, the key to the mystery of the intense Raman signal in this otherwise long-range-ordered “centrosymmetric” perovskite is related to local structural disorder created by lattice oxygen vacancies.

The cold-induced vasodilation (CIVD) response of the human body to Arctic-like environments helps delay or prevent cold injuries to peripheral regions, such as the hands and feet. To more comprehensively predict the thermal responses of these body regions to cold stress, here we extended our previously developed and validated anatomically accurate three-dimensional whole-body thermoregulatory human model by incorporating a new phenomenological formulation of the CIVD mechanism. In this formulation, we modulated the cyclic vasodilation and vasoconstriction flow of warm blood from the body core to the peripheral regions solely by determining the heat-transfer exchange between the skin and the surrounding environment, and deactivated it when the core body temperature decreased to 36.5 °C. In total, we calibrated and validated the model using eight distinct studies involving 153 unique male subjects exposed to 10 diverse experimental conditions, including cold-air exposure of the whole body as well as air exposure and cold-water immersion of the hand or the foot. With CIVD incorporated, the model predictions generally yielded root mean square errors (RMSEs) of © 2024

The transport behavior of contaminants through a permeable reactive barrier (PRB)-aquifer system is complex due to the diverse physical and chemical properties of the PRB and aquifer. Analytical or semi-analytical solutions for multispecies contaminant transport in a PRB-aquifer system of dual-domain are indispensable tools for enhancing our understanding of the effectiveness of PRB systems in remediating primary contaminant present in groundwater and its degradation byproducts. Many of the existing analytical or semi-analytical solutions derived for multispecies transport in a PRB-aquifer system presume an equilibrium sorption process between the contaminants in the aqueous and solid phases of both the up-gradient PRB and down-gradient aquifer. Past studies have unequivocally illustrated that nonequilibrium sorption process can profoundly affect contaminant transport within the subsurface environment. This study is thus designed to develop a novel semi-analytical solution for transport of multispecies, encompassing an original contaminant and its degradation byproducts, while considering nonequilibrium sorption within a PRB–aquifer system. The derived semi-analytical solution is shown to be both correct and accurate, with a comparative analysis revealing its numerical results to be closely consistent with those generated from the numerical solution. The results indicate that the kinetic sorption process plays a crucial role in influencing the effectiveness of using a PRB system for remediation purposes. The nonequlibrium sorption model forecasts higher concentrations compared to those predicted by the equilibrium sorption model. However, the difference between nonequlibrium sorption model and equlibrium sorption model diminishes as the kinetic sorption rate constant increases. This suggests that the length of the PRB might be underestimated when using an analytical solution assuming equilibrium sorption as the PRB design tool, especially in the scenarios with low

Oxytocin (OT) is a hormone with a short half-life that is released from the posterior pituitary gland into the bloodstream. It plays an important role in childbirth, breastfeeding, and social behavior in humans and animals. However, the endogenous OT system, including plasma OT pharmacokinetics, is not fully understood. In this study, we used a click chemistry probe to discover a novel OT-binding protein in human serum and identified C4a, a peptidase-cleaved fragment of complement component 4 (C4). A direct association between OT and C4a was also confirmed. Upon knocking out Slp gene, which is one of the two mouse C4 genes, the level of free form of plasma OT was higher in Slp knockout (Slp^−/−) mice than in wild-type (Slp^+/+) mice after intraperitoneal OT injection. In addition, open-field tests revealed that social interactions were higher in Slp^−/− mice than Slp^+/+ mice. An in vitro blood-brain barrier model showed that C4a neither inhibited nor accelerated receptor for advanced glycation end-product (RAGE)-dependent brain transport in OT. Our data validate the novel concept that C4a with OT-binding capacity can alter the dynamics of the free form of OT concentrations in the plasma, which may disturb the availability of OT to the brain, resulting in an interruption of OT-associated social behavior. © 2025 The Author(s)

The immediate connections between land cover, unsaturated zone and shallow unconfined aquifer support the premise that groundwater quality may be affected by the land use and the hydrogeological properties. This study aims to comprehensively assess the impact of land use and the hydrogeological properties on groundwater quality. First, correlations between 24 variables, including 12 hydrochemical parameters of groundwater quality, area percentage of 8 land use pattern and thicknesses of 4 geological material types at or around 123 monitoring wells established in shallow aquifers are statistically examined. Second, the factor analysis is performed to identify the four most important factors contributing to 53.33 % of the total variance. Factor 1 (seawater salinization) can be characterized by high loadings of SO 4 2− , Cl − , Ca 2+ , Mg 2+ , Na + , and K + and a medium loading with land use for aquaculture but an ambiguous correlation with the hydrogeological properties. Factor 2 (arsenic enrichment) can be characterized by high loadings of total organic carbon (TOC), As and HCO 3 − , but low loadings of both land use and hydrogeological properties. Factor 3 (nitrate pollution) with high loadings of NO₃⁻-N shows a high correlation with land use for fruit farming, and also has a high correlation with the gravel thickness constituting unsaturated soil. Factor 4 (reductive dissolution of Fe 2+ and Mn 2+ ) with high loadings of Mn 2+ and Fe 2+ , is negligibly impacted by both land use and hydrogeological properties. The computed scores for these factors can be mapped and used as the predictive tool for the occurrence of groundwater pollutant or to demarcate those areas where groundwater is more vulnerable to specific chemicals. © 2022, The Authors.

Background: 6-Mercaptopurine (6-MP) is a potential anti-cancer agent which its therapeutic and limitation applicability due to its high toxicity. Objective: Herein, 6-MP was loaded into tri-layered sandwich nanofibrous scaffold (the top layer composed of poly methyl methacrylate/polycaprolactone (PMMA/PCL), the middle layer was PCL/PMMA/6-MP, and the bottom layer was PCL/PMMA to improve its bioactivity, adjusting the release-sustainability and reduce its toxicity. Methods: Electrospun trilayered nanofibers composed of PCL/PMMA were utilized as nanomats for controlling sustained drug release. Four groups of sandwich scaffold configurations were investigated with alteration of (PMMA: PCL) composition. Results: The sandwich scaffold composed of 2%PCL/4%PMMA/1%6-MP showed the best miscibility, good homogeneity and produced the smoothest nanofibers and low crystallinity. All fabricated 6-MP-loaded-PCL/PMMA scaffolds exhibited antimicrobial properties on the bacterial and fungal organisms, where the cytotoxicity evaluation proved the safety of scaffolds on normal cells, even at high concentration. Scaffolds provided a sustained-drug release profile that was strongly dependent on (PCL: PMMA). As (PCL: PMMA) decreased, the sustained 6-MP release from PCL/PMMA scaffolds increased. Results established that ~18% and 20% of 6-MP were released after 23h from (4%PCL/4%PMMA/1%6-MP) and (2%PCL/4%PMMA/1%6-MP), respectively, where this release was maintained for more than 20 days. The anti-cancer activity of all fabricated scaffolds was also investigated using different cancerous cell lines (e.g., Caco-2, MDA, and HepG-2) results showed that 6-MP-loaded-nanofibrous mats have an anti-cancer effect, with a high selective index for breast cancer. We observed that viability of a cancer cell was dropped to about 10%, using nanofibers containing 2% PCL/4%PMMA/1%6-MP. Conclusion: Overall, the PCL: PMMA ratio and sandwich configuration imparts a tight control on long-term release profile and
