AbstractThe presence of microplastics (MPs) is rapidly increasing in the environment, posing a significant threat to public health and the ecosystem. To monitor the impact of MPs, it is crucial to have standardized detection methods and MPs remediation techniques. Therefore, this study aimed to use tannic acid-coated magnetite nanoparticles to recover MPs, specifically polystyrene (PS) and polyethylene terephthalate (PET), from water bodies. A facile method for MPs recovery was established using the synthesized tannic acid-coated magnetite (TA-Fe3O4) as an adsorbent. TA-Fe3O4 was synthesized using tannic acid, iron (II) sulfate heptahydrate, and iron (III) chloride hexahydrate through a one-pot co-precipitation method. The adsorbent material was then characterized using a scanning electron microscope coupled with an energy dispersive x-ray spectroscopy (SEM–EDS), x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, zeta potential, and N2 adsorption–desorption (BET) techniques, confirming its successful synthesis. The maximum adsorption efficiencies for PS and PET were 83% and 98%, respectively, under the experimental conditions of pH 6–7, a contact time of 300 min, an adsorbent dose of 2.5 g/L, and an initial MPs concentration of 1.25 g/L. The study also found that the presence of ions in wastewater had a significant effect on MP recovery. However, when it came to recovering MPs from the spent adsorbent, the maximum values were observed in an acidic medium at pH 3–4 under sonification conditions. In conclusion, TA-Fe3O4 showed potential and efficiency in the recovery of MPs in aqueous media. However, further investigation is needed to improve the method and explore its application for multi-MPs recovery performance.
Love and Organizing in the Context of the Base of the Pyramid: An Integrative Justice Perspective
Authors: Santos Nicholas J.C. , Facca-Miess Tina M. 
Published: July 2024

AbstractThis paper provides an overview of the Integrative Justice Model (IJM) for impoverished populations that was introduced in the marketing literature in the year 2009. The IJM was developed as a normative ethical framework to guide the growing corporate interest in the base of the pyramid (BoP) market to be fair and just to all parties but particularly the impoverished customer. In an impersonal marketplace that often exploits the less advantaged participant, the IJM provides five characteristics of “just” market situations. These are an authentic non-exploitative engagement, value co-creation, investment in future consumption, stakeholder interest representation and long-term profit management. At the heart of the IJM is love that flows from a recognition of the inherent dignity of those at the BoP and the need to respect and uphold that dignity in the marketplace. The hope is that as companies embrace the IJM in their functioning it will result in a marketplace that is fair, just, humanistic and loving.
The impact of the Bank of Japan’s exchange traded fund and corporate bond purchases on firms’ capital structure
Authors: Nguyen Thuy Linh 
Published: July 2024

AbstractThis study examines how the Bank of Japan’s (BOJ’s) exchange-traded fund (ETF) and corporate bond (CB) purchases affect the capital structure of Japanese listed firms. The results first suggest that the BOJ’s ETF purchases reduced the equity risk premium for firms included in the purchases, thereby lowering their cost of equity. These firms issued more stocks and became less dependent on bond debt and bank loans than control firms, resulting in a lower level of leverage. On the other hand, the BOJ’s CB purchases lowered the risk premium of bonds eligible for such purchases, which implies a decline in the cost of bond debt. Firms eligible for CB purchases issued more bonds, while reducing bank debt but to a smaller extent, thus having higher leverage than firms not eligible for CB purchases. Categorizing firms into four groups based on whether their stocks were included in ETF purchases and/or their bonds were eligible for CB purchases further shows that the policy impacts on firm financing have differed depending on which group a firm fell in. These results indicate that the BOJ’s ETF and CB purchases have had a considerable impact on the cost of capital, securities issuance activities, and corporate capital structure.
Sexual dimorphism in the Hungarian golden jackal population: analysing body and skull size and shape
Authors: Csányi Erika , Sándor Gyula 
Published: July 2024

AbstractDefining species within the Canidae family is challenging due to morphological convergence, behavioral plasticity, traditional taxonomic limitations, and possible hybridisation. This challenge is timely with the recent population and range expansion of the golden jackal (Canis aureus). Exploring their morphological data and sexual dimorphism is essential for identifying factors driving their success in new habitats. The proven hybridization of golden jackals with dogs and wolves may affect species description, population dynamics, and genetic diversity, impacting conservation strategies. This study, for the first time, conducts a morphometric analysis of golden jackals in Somogy County, Hungary, to prove sexual size dimorphism (SSD) in body and skull and sexual shape dimorphism (SShD) in skull across juvenile and adult age groups. 719 golden jackals (362 females and 357 males) were collected between January 2021 and January 2023. Descriptive statistics revealed significant SSD in body and skull measurements among both age groups, with males generally larger than females, particularly in body mass (11.72% in juveniles and 13.37% in adults). Most skull dimensions differed significantly between sexes and age groups, except for foramen magnum height, foramen magnum width, and postorbital breadth among juveniles and foramen magnum height and postorbital breadth among adults. We used principal component analyses (PCA) on raw dimension data and the log shape ratio method to extract shape information. Linear discriminant analysis (LDA) explored skull SShD between sexes. Notably, our study achieved over 71% accuracy in sex classification, illustrating the clear presence of SShD of the skull in golden jackals across both age groups. Our study provides a comprehensive database of golden jackals in the overpopulated Hungarian habitat, which will be helpful for further research on ecology, behavior, and conservation management.

AbstractThe market for microbial gums such as xanthan, gellan, dextran, and curdlan is continuously expanding, driven by their increasing application in various industries including petroleum, pharmaceuticals, cosmetics, and food, with the latter accounting for approximately 50% of global usage. To meet the growing demand and improve sustainability, there is a need to enhance production efficiency and reduce costs. This article addresses these issues by examining recent advancements and emerging trends in microbial gum production and application. By highlighting patented technologies and innovative approaches, the article aims to provide a comprehensive understanding of how the industry can achieve higher yields and economic viability. Despite being produced by different microorganisms, these gums are synthesized under similar conditions, such as pH, temperature, and medium composition. The purification or downstream processes for these gums are also comparable, primarily involving solvent precipitation, centrifugation for separation, and drying. Significant advances in gum production include genetic improvement of microbial strains to improve biopolymer performance. Additionally, alternative media are being explored, either by optimizing nutrient availability or deprivation, or by using agroindustrial by-products to reduce production costs. Engineering improvements are another strategy: bioreactor characteristics, fermentation conditions and modes of operation, and advances in downstream process are highlighted. Furthermore, the text explores emerging trends in the application of microbial gums in the food sector. Microbial gums applications are not limited to their traditional action as emulsifiers and stabilizers, but expands to new uses in biodegradable packaging films and as antioxidant and prebiotic food ingredient.
Hidden Large Aerosol‐Driven Cloud Cover Effect Over High‐Latitude Ocean

Published: July 2024

AbstractUnderstanding how aerosols affect cloud cover is critical for reducing the large uncertainty of the aerosol‐cloud interaction (ACI). The 2014 Holuhraun effusive eruption in Iceland resulted in a significant increase in cloud drop number concentration (Nd) relative to the climatological Nd observed during periods of relatively infrequent volcanic activity. Previous studies show a significant “Twomey” effect during this eruption; however, aerosol‐induced changes in cloud fraction (Cf) appeared negligible. This leads to the question of why changes in aerosols do not cause Cf changes. To address this question, prediction models were derived to predict Cf based on Nd and meteorological parameters. These validated models allow us to investigate aerosol perturbations on Cf in various Nd scenarios by controlled meteorological conditions. Here our analysis unveiled that the increase in Nd was primarily observed under polluted conditions where Nd surpassing the threshold of 60 cm−3. After this point, cloud cover stops increasing even as Nd increases. On the contrary, the cloud cover did increase by 9.0% under conditions of clean backgrounds (Nd < 60 cm−3). Accordingly, the aerosol‐driven cloud adjustment is hidden behind the seemingly insignificant cloud cover effect in areas with large background Nd. These findings provide insights into the importance of considering background Nd and the saturation status of cloud covers in ACI studies.
Insights Into Urban Heat Island and Heat Waves Synergies Revealed by a Land‐Surface‐Physics‐Based Downscaling Method

AbstractResearchers have recently focused on the interplay of the urban heat island (UHI) effect and heat waves (HWs). However, the synergies of these two phenomena remains inconclusive at present. To address this gap, this study investigated UHIs and HWs synergies during the last 30 years in the Tokyo metropolitan area, through a unique and novel approach named Land‐Surface‐Physics‐Based Downscaling (LSP‐DS). LSP‐DS integrates the widely used Noah‐Multiparameterization (Noah‐MP) land‐surface model coupled with urban canopy‐process physics, aiming to conduct high‐resolution, long‐term urban‐specific simulations with much less computational resources. Our comprehensive analysis combining observation data and numerous LSP‐DS simulations confirms exacerbated UHIs during HWs. Specifically, HWs amplify the temperature differences between urban and rural environments, which is quantified by UHI intensity (UHII). During HWs, UHII increased more at night in inland areas and more during daytime in coastal areas. HWs present especially a heightened threat to coastal regions where daytime UHII increased by approximately 1°C during HWs. The Bowen ratio can explain the increase in the daytime UHII, and the daytime accumulated storage heat increase during HWs can explain the increase in nighttime UHII. Based on future projections of the increasing frequency of high temperatures, our findings highlight the impending heat‐related health challenges faced by urban residents.
Separating Common Signal From Proxy Noise in Tree Rings
Authors: McPartland M. Y. , Dolman A. M. , Laepple T. 
Published: July 2024

AbstractTree rings are the most widely‐used proxy records for reconstructing Common Era temperatures. Tree‐ring records correlate strongly with temperature on an interannual basis, but studies have found discrepancies between tree rings and climate models on longer timescales, indicating that low‐frequency noise could be prevalent in these archives. Using a large network of temperature‐sensitive tree‐ring records, we partition timeseries variance into a common (i.e., “signal”) and non‐climatic (i.e., “noise”) component using a frequency‐resolved signal‐to‐noise ratio (SNR) analysis. We find that the availability of stored resources from prior years (i.e., biological “memory”) dampens the climate signal at high‐frequencies, and that independent noise reduces the SNR on long timescales. We also find that well‐replicated, millennial‐length records had the strongest common signal across centuries. Our work suggests that low‐frequency noise models are appropriate for use in pseudoproxy experiments, and speaks to the continued value of high‐quality data development as a top priority in dendroclimatology.
Energy Conversion in the Dip Region Preceding Dipolarization Front

Published: July 2024

AbstractDipolarization fronts (DFs), characterized by sharp increases in the northward magnetic field and usually preceded by magnetic dips, are suggested to play an important role in energy conversion and transport in the magnetotail. It has been documented that strong energy conversion typically develops right at the fronts. Here we present spacecraft observations of electron‐scale energy conversion (EEC) developed inside the dip region ahead of a DF, by using high‐cadence data from the Magnetospheric Multiscale Mission. The EEC, with magnitude comparable to that at the front, is primarily driven by ion current and electron‐scale electric field. The electric field inside the dip is provided by electrostatic waves fed by lower hybrid drift instability, which experiences temporal decaying. Such decaying leads to nonhomogeneity of EEC along the dawn‐dusk direction. These results, uncovering a new channel for DF‐driven energy conversion, can provide important insights into understanding energy transport in the magnetotail.
Whistler‐Mode Waves on Density and Magnetic Shelves
Authors: Nejad Salman A. , Streltsov Anatoly V. 
Published: July 2024

AbstractThis study presents a recent finding of magnetic shelf structures and packages of whistler‐mode waves in the data obtained from the Magnetospheric Multiscale (MMS) mission satellite in the equatorial magnetosphere. These observations are compared with the waves observed on density shelves by the NASA Van Allen Probes (aka RBSP) mission. By employing simulations of the electron‐MHD model, we explain that similar to the density shelf ducting, magnetic shelves effectively guide whistler‐mode waves along the ambient magnetic field with little attenuation. The parameters of the guided waves depend on the parameters of the shelves. We discuss the similarities and differences of the wave guided by the density and magnetic field shelf‐like structures. The simulations successfully reproduce the parameters of the observed waves.
Stress Field Dynamics and Fault Slip Potential in the Paradox Basin
Authors: Dvory N. Z. , McLennan J. D. 
Published: July 2024

AbstractThe Paradox Basin, straddling Utah, Colorado, Arizona, and New Mexico is characterized by an intricate amalgamation of evaporites and clastic layers and is dominated by prominent salt walls and related subsurface structures. Our research offers a new examination of the stress distribution across the basin, deriving from continuous and discrete stress measurements conducted in boreholes in the region and focal mechanism analysis, emphasizing variations over salt structures. Integrating Coulomb failure criteria with probabilistic methods, we assess potential fault movements resulting from fluid pressure alterations. Our approach provides a comprehensive understanding of the Paradox Basin's state of stress, showing a continuous change of the maximum horizontal stress orientation from N‐S at the Wasatch Fault Zone to WNW‐ESE in the northern part of the Paradox Basin and to WSW‐ENE in the southern part of the basin. Further East, into the Colorado Plateau and the Uncompahgre Uplift, the SHmax orientation becomes E‐W. Decoding stress orientation dynamics has enabled critical insights into fault slip potential, especially in the basin's northern region. The salt wall faults are less likely to slip, and the Paradox Formation's evaporite and clastic rock sequence can serve as a potential low seismic risk target for carbon storage and hydrocarbon extraction.

Abstract
Background/Objectives
Obesity and chronic oedema/lymphoedema are two distinct but related conditions, rarely investigated together. The aim was to study the impact of increased weight on chronic oedema and related factors.

Subjects/Methods
A cross-sectional study, 38 centers, nine countries. Patients with clinically confirmed chronic oedema/lymphoedema of the leg were included. Weight category was estimated as: normal weight (BMI 20–30), class I-II obesity (BMI 30–40), or class III obesity (BMI > 40). Factors were tested for an association with increased weight, using a multivariable model.

Results
A total of 7397 patients were included; 43% with normal weight, 36% class I-II obesity and 21% class III obesity. Increased weight was associated with more advanced stages of chronic oedema (ISL stage III; the most advanced form); affecting 14% in normal weight, 18% class I-II obesity and 39% class III obesity (p < 0.001). Ten factors were independently associated with increased weight: diabetes (OR 2.4), secondary lymphoedema (OR 2.7), cellulitis/erysipelas within 12 months (OR 1.2), bilateral lymphoedema (OR 3.6), compression therapy (OR 2.1), increased swelling duration (1–2 years OR 1.3, 2–5 years OR 2.5, 5–10 years OR 3.6, >10 years OR 3.5) decreased mobility (walking with aid OR 1.9, being chair bound OR 1.2) and age (reference<45 years; 45–64 years OR 1.5, 75–84 years OR 0.6, 85+ years OR 0.2). Increased weight was associated with a lower presentation of peripheral arterial disease (OR 0.7) and poorer chronic oedema control (OR 0.8). Patients with obesity had lower function, appearance and more severe symptoms (LYMQOL) and lower quality of life (EuroQol).

Conclusions
Obesity negatively impacts chronic oedema, leading to more advanced stages. Achieving good control of swelling with compression is more difficult in these patients. Increased awareness of chronic oedema/lymphoedema as a complication of obesity is important for early detection and for developing effective strategies to prevent and manage them.
Semaphorin 3C (Sema3C) reshapes stromal microenvironment to promote hepatocellular carcinoma progression

Published: July 2024

AbstractMore than 90% of hepatocellular carcinoma (HCC) cases develop in the presence of fibrosis or cirrhosis, making the tumor microenvironment (TME) of HCC distinctive due to the intricate interplay between cancer-associated fibroblasts (CAFs) and cancer stem cells (CSCs), which collectively regulate HCC progression. However, the mechanisms through which CSCs orchestrate the dynamics of the tumor stroma during HCC development remain elusive. Our study unveils a significant upregulation of Sema3C in fibrotic liver, HCC tissues, peripheral blood of HCC patients, as well as sorafenib-resistant tissues and cells, with its overexpression correlating with the acquisition of stemness properties in HCC. We further identify NRP1 and ITGB1 as pivotal functional receptors of Sema3C, activating downstream AKT/Gli1/c-Myc signaling pathways to bolster HCC self-renewal and tumor initiation. Additionally, HCC cells-derived Sema3C facilitated extracellular matrix (ECM) contraction and collagen deposition in vivo, while also promoting the proliferation and activation of hepatic stellate cells (HSCs). Mechanistically, Sema3C interacted with NRP1 and ITGB1 in HSCs, activating downstream NF-kB signaling, thereby stimulating the release of IL-6 and upregulating HMGCR expression, consequently enhancing cholesterol synthesis in HSCs. Furthermore, CAF-secreted TGF-β1 activates AP1 signaling to augment Sema3C expression in HCC cells, establishing a positive feedback loop that accelerates HCC progression. Notably, blockade of Sema3C effectively inhibits tumor growth and sensitizes HCC cells to sorafenib in vivo. In sum, our findings spotlight Sema3C as a novel biomarker facilitating the crosstalk between CSCs and stroma during hepatocarcinogenesis, thereby offering a promising avenue for enhancing treatment efficacy and overcoming drug resistance in HCC.

Abstract
Study design
Secondary analysis of a randomized, multi-center, placebo-controlled study(Sygen®).

Objectives
To evaluate racial differences in serological markers in individuals with spinal cord injury(SCI) across the first year of injury.

Setting
Hospitals in North America.

Methods
Serological markers (e.g.,cell count, liver, kidney, and pancreatic function, metabolism, and muscle damage) were assessed among 316 participants (247 White, 69 Black) at admission, weeks 1, 2, 4, 8, and 52 post-injury. Linear mixed models were employed to explore the main effects of time, race (Black vs. White), and their interaction, with adjustment of covariates such as study center, polytrauma, injury (level, completeness), treatment group, and sex.

Results
A main effect of race was observed where White individuals had higher alanine transaminase, blood urea nitrogen(BUN), BUN/Creatinine ratio, sodium, and chloride, while Black individuals had higher calcium, total serum protein, and platelets. For markers with interaction effects, post-hoc comparisons showed that at week 52, White individuals had higher mature neutrophils, hematocrit, hemoglobin, mean corpuscular hemoglobin, albumin, and triglycerides, and Black individuals had higher amylase. Eosinophils, monocytes, red blood cells, aspartate aminotransferase, bilirubin, cholesterol, partial thromboplastin time, urine specific gravity, urine pH, CO2, and inorganic phosphorus did not differ between races.

Conclusions
Our results revealed racial differences in serological markers and underscores the importance of considering race as a determinant of physiological responses. Future studies are warranted to explore the causes and implications of these racial disparities to facilitate tailored clinical management and social policy changes that can improve health equity.
