Published: March 2024

AbstractOrganic redox molecules have attracted considerable attention because of their abundant availability and excellent design flexibility. For practical applications, these molecules must be anchored onto scaffolds such as polymers to prevent crystallization and elution into the electrolyte. In this study, we explore the use of polyhedral oligomeric silsesquioxane (POSS) derivatives as scaffolds for anthraquinone (AQ) and hydroquinone. We investigated the cage structure of POSS and the number of redox units incorporated. Notably, a corner‐opened POSS (CO‐POSS) variant with three AQ units exhibited reversible redox behavior under neutral, acidic, and basic conditions. Furthermore, we examined the air‐battery performance of AQ‐modified CO‐POSS as an anode‐active material.
Evolution of Excited‐State Behaviors of Gold Complexes, Nanoclusters and Nanoparticles
Authors: Zeng Linlin , Zhou Meng , Jin Rongchao 
Published: March 2024

AbstractMetal nanomaterials have been extensively investigated owing to their unique properties in contrast to bulk counterparts. Gold nanoparticles (e. g., 3–100 nm) show quasi‐continuous energy bands, while gold nanoclusters (<3 nm) and complexes exhibit discrete energy levels and display entirely different photophysical properties than regular nanoparticles. This review summarizes the electronic dynamics of these three types of gold materials studied by ultrafast spectroscopy. Briefly, for gold nanoparticles, their electronic relaxation is dominated by heat dissipation between the electrons and the lattice. In contrast, gold nanoclusters exhibit single‐electron transitions and relatively long excited‐state lifetimes being analogous to molecules. In gold complexes, the excited‐state dynamics is dominated by intersystem crossing and phosphorescence. A detailed understanding of the photophysical properties of gold nanocluster materials is still missing and thus calls for future efforts. The fundamental insights into the discrete electronic structure and the size‐induced evolution in quantum‐sized nanoclusters will promote the exploration of their applications in various fields.

Published: March 2024

AbstractThe construction of full‐color fluorescence systems has received widespread attention because of their applications in lighting materials, optoelectronic materials, and fluorescent probes. However, for the full‐color luminescence system based on trichromatic materials, there are no connections between materials of different luminescent colors. Herein, A new donor‐acceptor dye with red fluorescence was synthesized. The dye displays excellent optical properties of short half‐peak width and strong fluorescence emission. An effective energy transfer process from the dansyl donor to the acceptor was observed with a transfer efficiency of 81 %. Further, dyes with green and blue fluorescence were introduced to construct a full‐spectrum fluorescent system. Through exchange reactions of Diels‐Alder dynamic covalent bonds, red, green, and blue luminescence can be converted. This work provides a new idea for the design of full‐color fluorescent materials.

Published: March 2024

AbstractThis study examined autonomic nervous system activity (respiratory sinus arrhythmia [RSA]) as a biomarker of psychopathology in an ethnically and socioeconomically diverse sample (N = 57) of young children ages 4–7 years. RSA was measured at baseline and across four standardized tasks designed to assess self‐regulation in both affective (i.e., “hot”) and cognitive (i.e., “cool”) contexts during early childhood. Our findings reveal that age moderated RSA activity, such that reduced RSA suppression was associated with a heightened risk of externalizing problems among older children during “cool” and “hot” contexts; for younger children, only RSA suppression during “hot” contexts predicted externalizing risk. The influence of socioeconomic disadvantage did not moderate the relationship between RSA and the risk of psychopathology, and there were minimal associations between RSA suppression and internalizing symptoms at this age range. These results suggest that autonomic variability may be a more effective predictor of psychopathology risk in older children, perhaps as they transition into formal schooling and face increasingly complex cognitive and social demands. Findings have implications for the identification of psychopathology in early developmental periods when regulation over emotions becomes essential for academic and social success.

Published: March 2024

AbstractAimsPrevious studies have found that a single liver enzyme may predict gestational diabetes mellitus (GDM), but the results have been inconsistent. This study aimed to explore the associations of liver enzymes in early pregnancy with risk of GDM, as well as to independently rank risk factors.MethodsThis prospective cohort study included 1295 women who underwent liver enzyme measurements during early pregnancy and completed GDM assessment in mid‐pregnancy. Logistic regression and restricted cubic spline analyses were conducted to assess the relationship between liver enzymes and risk of GDM. Back‐propagation artificial neural network was performed to rank independently risk factors of GDM.ResultsWomen diagnosed with GDM exhibited significantly higher levels of liver enzymes than those without GDM (all p < 0.05). The highest quartile of liver enzymes was associated with higher risk of GDM compared with the lowest quartile, with adjusted odds ratio (ORs) ranging from 2.76 to 8.11 (all p < 0.05). Moreover, the ORs of GDM increased linearly with liver enzymes level (all P for overall association <0.001). Furthermore, Back‐propagation artificial neural network identified γ‐gamma‐glutamyl transferase (GGT) as accounting for the highest proportion in the ranking of GDM risk prediction weights (up to 20.8%).ConclusionsSingle or total elevations of liver enzymes in early pregnancy could predict the GDM occurrence, in which GGT, alkaline Phosphatase, and aspartate aminotransferase were the three most important independent risk factors.
Is nonrainfall water a likely water source for arid and semiarid biocrusts? A critical perspective
Authors: Kidron Giora J. 
Published: March 2024

AbstractIt is commonly believed that nonrainfall water (NRW) serves as an important and even a central source of water for biocrusts in arid and semiarid regions. Known also as biological soil crusts, they mainly consist of cyanobacteria (that dwell within the upper 2 mm of the soil) and crustose chlorolichens that commonly protrude 1–2 mm above ground. It is commonly assumed that due to the prolonged dry season in deserts, a constant source of water is required for their survival. Overestimated, nonrealistic NRW values, whether due to the use of improper measurement devices or erroneous interpretation of the recorded values as well as instances during which distillation was regarded as dewfall, supported the notion that the amounts of NRW are sufficiently high to allow for biocrust activation. In the current commentary, a short account of the reasons that led scholars to believe that NRW may be utilized by biocrusts is presented, and the findings that led to this belief are critically analysed. It is argued that the amounts of NRW reaching the surface are below the critical thresholds of 0.05 and 0.1 mm required for net photosynthesis by the chlorolichens and cyanobacteria, respectively. Moreover, it is argued that even if these thresholds are seldom reached, their duration is too short to result in net carbon gain. As shown for the dewy Negev and may be applicable for other arid and semiarid regions, biocrusts rely on rainwater for their growth and survival.

AbstractObjectiveTo assess the adult Hungarian population's knowledge about and attitude toward epilepsy and compare the present findings with previous ones in 1994 and 2000.MethodsWe performed a cross‐sectional survey of the Hungarian adult population from 28th February to 8th March 2023. A non‐probability quota sampling with a random walk method was used. We applied the computer‐assisted personal interviewing (CAPI) method and used a multicriteria weighting procedure to correct for bias along the main sociodemographic variables. To detect changes over time, we used chi‐squared tests, and to analyze the effect of sociodemographic characteristics, we applied multivariate logistic regression.ResultsOne thousand participants (53.1% women, mean age 48.1 ± 16.75 years) representing Hungary's population were interviewed yielding a response rate of 80.3%. 26.3% knew someone with epilepsy (55.9% in 1994 and 51.9% in 2000), and 30.8% saw an epileptic seizure (58% in 1994 and 55.3% in 2000). Compared to the young, fewer adults and elderly people knew someone with epilepsy or had seen a seizure. Like in 1994 and 2000, 16.6% reported objection to their children's interaction with people with epilepsy; however, in the present study, significantly fewer people opposed their children marrying or working together with epileptic people, indicating a change in attitude (p < 0.0001). Rural residents had less objection to their children's interaction with people with epilepsy (p < 0.05). People with secondary education objected significantly more often than those with primary education to their children's interaction (p = 0.037), marriage to people with epilepsy (p = 0.043), or their having equal employment (p = 0.008). Higher education people were as “permissive” as those with primary education.SignificanceCertain parameters of familiarity and attitude markers of the Hungarian population toward epilepsy have improved. These tendencies are promising, but work is still needed; our results will hopefully evoke educational programs and campaigns against negative attitudes.Plain Language SummaryThe knowledge of the Hungarian population about epilepsy and their attitude toward people with epilepsy has been improved since 1994. People from rural areas have shown more acceptance for people with epilepsy. Those people who completed secondary education were significantly more prone to stigmatization than those with primary education.

AbstractObjectiveTo compare the pelvic lymph node involvement and risk of recurrence in patients with human papillomavirus (HPV)‐associated endocervical adenocarcinoma stage IA2‐IB1 undergoing hysterectomy and/or trachelectomy plus lymphadenectomy, according to Silva's classification system.MethodsA retrospective cohort study was performed in two Colombian cancer centers. The cases were classified according to the Silva classification system. Clinical, surgical, and histopathological variables were evaluated. Recurrence risk was analyzed by patterns A, B, or C. A logistic regression model was performed for tumor recurrence. The Kaplan–Meier method was used to estimate overall survival and disease‐free survival (DFS). A weighted kappa was performed to determine the degree of concordance between pathologists.ResultsA total of 100 patients were identified, 33% pattern A, 29% pattern B, and 38% pattern C. The median follow‐up time was 42.5 months. No evidence of lymph node involvement was found in patients classified as A and B, while in the C pattern was observed in 15.8% (n = 6) of cases (P < 0.01). There were 7% of cases with recurrent disease, of which 71.5% corresponded to type C pattern. Patients with Silva pattern B and C had 1.22‐ and 4.46‐fold increased risk of relapse, respectively, compared with pattern A. The 5‐year DFS values by group were 100%, 96.1%, and 80.3% for patterns A, B, and C, respectively.ConclusionFor patients with early‐stage HPV‐associated endocervical adenocarcinoma, the type C pattern presented more lymph node involvement and risk of recurrence compared to the A and B patterns. The concordance in diagnosis of different Silva's patterns by independents pathologists were good.
Endangered beach mouse resistance to a Category 5 hurricane is mediated by elevation and dune habitat

Published: March 2024

AbstractCoastal ecosystems and their endemic taxa are under threat from hurricanes that are increasingly frequent and severe due to climate change—leading to a need to better understand factors associated with species' resistance (capacity to withstand) and resilience (capacity to rebound) to these storms. The beach mouse species complex (Peromyscus polionotus spp.) is a representative endangered group of rodents tightly associated with such coastal habitats. We examined track‐tube monitoring data of beach mice from Tyndall Air Force Base, Florida, USA, before and after the 2018 strike of Hurricane Michael, a Category 5 hurricane, and again before and after the 2020 strike of Hurricane Sally, a Category 2 hurricane. We applied dynamic occupancy models to track‐tube survey data to assess environmental factors associated with beach mouse initial occupancy and local extinction following Hurricane Michael. Beach mice exhibited high probabilities of detection and initial occupancy across most sites and all representative habitats before Hurricane Michael. Dynamic models revealed that local extinction probabilities of beach mice decreased with increasing elevation and dune habitat, followed by grassland, and scrub—highlighting high elevation dune as the primary driver of beach mouse resistance to storms. Extinction probability was not related to other factors like plant species percent cover or proximity to storm strike. Beach mice occurred at 100% of track‐tubes before and after Hurricane Sally. Beach mice are adapted to persist in dynamic coastal environments with regular hurricane strikes, as evidenced by their resistance and resilience following Hurricane Michael to reach 100% occupancy with high resistance to the weaker Hurricane Sally. However, as hurricanes become stronger and more frequent with global change, isolated populations of beach mice may be more susceptible to local extinction with the corresponding loss of elevation and dunes. High elevation, particularly in dune habitats, is an important mediator of resistance and resilience to hurricane impacts and should be considered in habitat restoration and reintroduction strategies, especially if relative elevation decreases with sea‐level rise.

AbstractClimate change poses a significant threat to global food security, and a comprehensive understanding of its impact on agricultural production is needed. We analysed the Scopus data set between 1993 and 2023. China occupies the leading position in terms of climate change production, and the United States occupies the comprehensive strength position with the largest citation strength output. Notably, a substantial 29% annual publication increase between 2000 and 2015 was noted. Despite prevailing research on specific facets, a pronounced gap exists in global‐scale studies focusing on the direct impact of climate change on agricultural production and yield, with a predominant concentration in regional analyses. Collaboration in this area continues to occur within developed nations, but the rate of growth at the international level is relatively low. In addition, the frequency of co‐occurrence analysis of keywords revealed that climate change and sustainability are the focal keywords, but yield, food security, irrigation and rice production have yet to be identified. The results of this research will help in designing a policy for water resource management for irrigation planning and an adaptative food security management strategy and provide a feature research guide.
Estimating the price elasticity of gasoline demand in correlated random coefficient models with endogeneity
Authors: Bates Michael , Kim Seolah 
Published: March 2024

SummaryWe propose a per‐cluster instrumental variable (PCIV) approach for estimating linear correlated random coefficient models in the presence of contemporaneous endogeneity and two‐way fixed effects. This approach estimates heterogeneous effects and aggregates them to population averages. We demonstrate consistency, showing robustness over standard estimators, and provide analytic standard errors for robust inference. In Monte Carlo simulation, PCIV performs relatively well in finite samples in either dimension. We apply PCIV in estimating the price elasticity of gasoline demand using state fuel taxes as instrumental variables. We find significant elasticity heterogeneity and more elastic gasoline demand on average than with standard estimators.

AbstractIn the study, we have shown the efficacy of an indigenously developed redox balancing chitosan gel with impregnated citrate capped Mn3O4 nanoparticles (nanogel). Application of the nanogel on a wound of preclinical mice model shows role of various signaling molecules and growth factors, and involvement of reactive oxygen species (ROS) at every stage, namely hemostasis, inflammation, and proliferation leading to complete maturation for the scarless wound healing. While in vitro characterization of nanogel using SEM, EDAX, and optical spectroscopy reveals pH regulated redox buffering capacity, in vivo preclinical studies on Swiss albino involving IL‐12, IFN‐γ, and α‐SMA signaling molecules and detailed histopathological investigation and angiogenesis on every stage elucidate role of redox buffering for the complete wound healing process.

AbstractSickle cell disease (SCD) patients are at higher risk of developing silent cerebral infarcts and overt stroke, which may reflect cognitive impairment, functional limitations, and worse quality of life. The cognitive function of Brazilian adult SCD patients (n = 124; 19–70 years; 56 men; 79 SS, 28 SC, 10 S/β0, 7 S/β+) was screened through Montreal Cognitive Assessment (MoCA) and correlated the results with possible predictive factors for test performance, including sociocultural, clinical, laboratory data and brain imaging. The Median MoCA score was 23 (8–30); 70% had a 25‐or‐less score, suggesting some level of cognitive impairment. There were no significant associations between MoCA results and any clinical or laboratory data in SS and SC patients; however, a significant correlation (P = 0.03) with stroke was found in HbS/β‐thalassemic patients. Correlations were further detected according to sociodemographic conditions, such as age (r = −0.316; P < 0.001), age at first job (r = 0.221; P = 0.018), personal (r = 0.23; P = 0.012) and per capita familiar incomes (r = 0.303; P = 0.001), personal (r = 0.61; P = 0), maternal (r = 0.536; P = 0), and paternal educational status (r = 0.441; P = 0). We further sought independent predictors of performance using multivariable regressions and increased education was an independent predictor of better scores in MoCA (0.8099, 95% confidence interval [CI]: 0.509–1.111). Brain imaging analysis showed significant and progressive atrophy in important cerebral areas related to memory, learning, and executive function. These data point to the high prevalence and impact of cognitive decline in adult SCD patients, mirrored in brain atrophic areas. It is also possible to observe the influence of sociodemographic conditions on patients’ cognitive performances and the need for creating focused therapeutic plans that address these deficiencies. Moreover, the absence of a significant correlation of MoCA values with stroke in the SS and SC groups may be related to the worst sociocultural and economic conditions of the Brazilian African descent population, in which the impact of low educational stimulation on cognitive function can outweigh even the anatomical damage caused by the disease.
