Published: July 2024

AbstractMagnetic Cu0.2Zn0.3Co0.5Fe2O4 nanoparticles were prepared by the rapid combustion method and characterized by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), x‐ray diffraction (XRD), and vibrating sample magnetometer (VSM). The average particle size and the saturation magnetization of the nanoparticles prepared at 400°C with 25 mL absolute alcohol were about 60.9 nm and 50 emu/g. The results of the experiment displayed that the adsorption process agreed with the pseudo‐second‐order kinetics model (R2 > 0.98) and Langmuir isotherm model (R2 = 0.9982), indicating that the adsorption of DB‐2BLN onto magnetic Cu0.2Zn0.3Co0.5Fe2O4 nanoparticles was monolayer chemisorption. ΔH (ΔH = −28.0135 kJ/mol) of the thermodynamic experiment was less than 0, indicating that the adsorption was an exothermic process. The effects of pH, initial concentration of dye, ionic strength, temperature, and adsorbent dosage on the adsorption process of DB‐2BLN onto magnetic Cu0.2Zn0.3Co0.5Fe2O4 nanoparticles and the regeneration performance of the nanoparticles were investigated. When the pH was determined to be 2 and the adsorbent dosage was 5 mg, the adsorption capacity reached the maximum. After 7 cycles, the removal rate of DB‐2BLN still reached 92.6% of that for the first adsorption, showing excellent regeneration performance. Finally, the electrochemical properties of the magnetic Cu0.2Zn0.3Co0.5Fe2O4 nanoparticles were investigated by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS).

Abstract
Acetochlor, as a commonly used pre-emergent herbicide, can be toxic to crops and affect production if used improperly. However, the toxic mechanism of acetochlor on plants is not fully understood. The present study used a combination of transcriptomic analysis and physiological measurements to investigate the effects of short-term (15-day) exposure to different concentrations of acetochlor (1, 10, 20 mg/kg) on the morphology, physiology, and transcriptional levels of pea seedlings, aiming to elucidate the toxic response and resistance mechanisms in pea seedlings under herbicide stress. The results showed that the toxicity of acetochlor to pea seedlings was dose-dependent, manifested as dwarfing and stem base browning with increasing concentrations, especially at 10 mg/kg and above. Analysis of the antioxidant system showed that from the 1 mg/kg treatment, malondialdehyde, superoxide dismutase, peroxidase, and glutathione peroxidase in peas increased with increasing concentrations of acetochlor, indicating oxidative damage. Analysis of the glutathione (GSH) metabolism system showed that under 10 mg/kg treatment, the GSH content of pea plants significantly increased, and GSH transferase activity and gene expression were significantly induced, indicating a detoxification response in plants. Transcriptomic analysis showed that after acetochlor treatment, differentially expressed genes in peas were significantly enriched in the phenylpropane metabolic pathway, and the levels of key metabolites (flavonoids and lignin) were increased. In addition, we found that acetochlor-induced dwarfing of pea seedlings may be related to gibberellin signal transduction. Environ Toxicol Chem 2024;43:2005–2019. © 2024 SETAC
Morphological patterns and spatial probability maps of the inferior frontal sulcus in the human brain
Authors: Nolan Erika , Loh Kep Kee , Petrides Michael 
Published: July 2024

AbstractThe inferior frontal sulcus (ifs) is a prominent sulcus on the lateral frontal cortex, separating the middle frontal gyrus from the inferior frontal gyrus. The morphology of the ifs can be difficult to distinguish from adjacent sulci, which are often misidentified as continuations of the ifs. The morphological variability of the ifs and its relationship to surrounding sulci were examined in 40 healthy human subjects (i.e., 80 hemispheres). The sulci were identified and labeled on the native cortical surface meshes of individual subjects, permitting proper intra‐sulcal assessment. Two main morphological patterns of the ifs were identified across hemispheres: in Type I, the ifs was a single continuous sulcus, and in Type II, the ifs was discontinuous and appeared in two segments. The morphology of the ifs could be further subdivided into nine subtypes based on the presence of anterior and posterior sulcal extensions. The ifs was often observed to connect, either superficially or completely, with surrounding sulci, and seldom appeared as an independent sulcus. The spatial variability of the ifs and its various morphological configurations were quantified in the form of surface spatial probability maps which are made publicly available in the standard fsaverage space. These maps demonstrated that the ifs generally occupied a consistent position across hemispheres and across individuals. The normalized mean sulcal depths associated with the main morphological types were also computed. The present study provides the first detailed description of the ifs as a sulcal complex composed of segments and extensions that can be clearly differentiated from adjacent sulci. These descriptions, together with the spatial probability maps, are critical for the accurate identification of the ifs in anatomical and functional neuroimaging studies investigating the structural characteristics and functional organization of this region in the human brain.

AbstractThis study assesses the reliability of resting‐state dynamic causal modelling (DCM) of magnetoencephalography (MEG) under conductance‐based canonical microcircuit models, in terms of both posterior parameter estimates and model evidence. We use resting‐state MEG data from two sessions, acquired 2 weeks apart, from a cohort with high between‐subject variance arising from Alzheimer's disease. Our focus is not on the effect of disease, but on the reliability of the methods (as within‐subject between‐session agreement), which is crucial for future studies of disease progression and drug intervention. To assess the reliability of first‐level DCMs, we compare model evidence associated with the covariance among subject‐specific free energies (i.e., the ‘quality’ of the models) with versus without interclass correlations. We then used parametric empirical Bayes (PEB) to investigate the differences between the inferred DCM parameter probability distributions at the between subject level. Specifically, we examined the evidence for or against parameter differences (i) within‐subject, within‐session, and between‐epochs; (ii) within‐subject between‐session; and (iii) within‐site between‐subjects, accommodating the conditional dependency among parameter estimates. We show that for data acquired close in time, and under similar circumstances, more than 95% of inferred DCM parameters are unlikely to differ, speaking to mutual predictability over sessions. Using PEB, we show a reciprocal relationship between a conventional definition of ‘reliability’ and the conditional dependency among inferred model parameters. Our analyses confirm the reliability and reproducibility of the conductance‐based DCMs for resting‐state neurophysiological data. In this respect, the implicit generative modelling is suitable for interventional and longitudinal studies of neurological and psychiatric disorders.
Three‐dimensional representation of the pure electric‐dipole and the mixed first hyperpolarizabilities: The modified unit sphere representation
Authors: Bonvicini Andrea , Champagne Benoît 
Published: July 2024

AbstractIn this work, the theory of the modified unit sphere representation (mUSR) has been proposed as a computational tool suitable for the three‐dimensional representation of the pure electric‐dipole [] as well as of the mixed electric‐dipole/magnetic‐dipole [ and ] or electric‐dipole/electric‐quadrupole [ and ] first hyperpolarizabilities. These five quantities are Cartesian tensors and they are responsible for the chiral signal in the chiroptical version of the hyper‐Rayleigh scattering (HRS) spectroscopy, namely the HRS optical activity (HRS‐OA) spectroscopy. For the first time, for each hyperpolarizability, alongside with the three‐dimensional representation of the whole (i.e., reducible) Cartesian tensors, the mUSRs are developed for each of the irreducible Cartesian tensors (ICTs) that constitute them. This scheme has been applied to a series of three (chiral) hexahelicene molecules containing different degrees of electron‐withdrawing (quinone) groups and characterized by the same (positive) handedness. For these molecules, the mUSR shows that, upon substitution, the most remarkable qualitative and semi‐quantitative (enhancement of the molecular responses) effects are obtained for the pure electric‐dipole and for the mixed electric‐dipole/magnetic‐dipole hyperpolarizabilities.

AbstractBACKGROUNDMesoporous‐nanostructured silica‐Prussian blue composite is a highly potential material for silver ions removal and recovery from wastewater. Intense interest has been shown in the use of Prussian blue (PB), one of the important coordinated materials and its analogues in removal of toxic and valuable ions.METHODSThe micro‐emulsion template method enables the synthesis of Prussian blue (PB) within silica pores, yielding a nanostructured mesoporous silica‐PB composite. This rapid synthesis technique allows for the direct fabrication of the composite from mixed precursor solutions within minutes. The resulting material is effective for selectively extracting silver ions from wastewater at a specific pH level.RESULTS AND DISCUSSIONIn summary, the synthesized SiO2‐Prussian blue composite was extensively analyzed using various techniques including XPS, HR‐TEM, SEM, STEM‐EDX elemental maps, TGA/TDA, and N2 adsorption/desorption measurements. The composite exhibited a BET surface area of 203 m2 g−1 and a total pore volume of approximately 0.283 cm3 g−1with mesopores centered around 20 nm. This mesoporous SiO2‐Prussian blue demonstrated significant effectiveness in removing silver ions, with a maximum adsorption capacity of 107.5 mg g−1. The Langmuir and Sips isotherms showed the best fit among various adsorption isotherm types, with R2 values exceeding 0.984. Additionally, kinetic analyses revealed that the pseudo‐second‐order model accurately described the adsorption of silver ions onto the synthesized adsorbent. The nano‐particles exhibit remarkable long‐term stability, maintaining good reproducibility even after five regeneration cycles. © 2024 Society of Chemical Industry (SCI).

AbstractPsychiatric genetic counseling (GC) has been associated with patient‐reported increases in empowerment (perceived control, emotional regulation, and hope). We sought to evaluate the extent to which patients' psychological state at the time of GC is related to changes in empowerment. Participants with a history of major depressive disorder and/or bipolar disorder that had been refractory to treatment underwent psychiatric GC remotely from 2022 to 2023. GC was performed by four genetic counselors and included discussion of perceived causes of illness, multifactorial inheritance, and protective factors. Empowerment, depression, and anxiety were measured immediately prior to GC via online survey by the GCOS‐16, PHQ‐9, and GAD‐7, respectively. Empowerment was re‐assessed 2 weeks later. In total, 66/161 (41.0%) invited individuals completed both the baseline and follow‐up surveys. Participants completing both surveys were 54.6% female, 84.8% white, and ranged in age from 22 to 78 years (mean = 54.8 years). Overall, a significant change in mean empowerment was not observed (p = 0.38); however, there were moderating effects by baseline psychological state. A multiple linear regression model incorporating PHQ‐9, GAD‐7 and baseline GCOS‐16 score predicted change in empowerment with a large effect (F = 5.49, R2 = 0.21, p < 0.01). A higher score on the PHQ‐9 was associated with decreases in empowerment from pre to post GC. Higher scores on the GAD‐7 and lower baseline GCOS‐16 scores were associated with increases in empowerment. Further, two‐way ANOVA was conducted to assess change in empowerment between subgroups based on the level of anxiety and depression. Those with low depression and high anxiety reported significant increases in empowerment (F = 6.64, p = 0.01). These findings suggest that psychiatric GC may be especially helpful to individuals experiencing anxiety and low baseline empowerment. Alternative approaches may be needed to best meet the needs of those experiencing significant depression.
Impact of international trade on the income gaps between formal and informal sectors: Evidence from China
Authors: Ma Xinxin 
Published: July 2024

AbstractUsing national longitudinal survey data, this study examines the impact of international trade on income gaps between formal and heterogeneous informal workers in China. The results demonstrate that the positive effect of trade on income is larger for informal employees and smaller for self‐employed workers compared to formal employees. The decomposition results indicate that the disproportionate geographic distribution in tradable regions widens the income gaps between employment sectors, while the difference in international trade income premiums widens the income gap between formal and informal employees and narrows the income gap between formal employees and self‐employed workers.

AbstractDengue fever (DF) is one of the common vector‐borne infections in tropical and subtropical regions worldwide. Liver involvement in DF is common and includes a wide spectrum of clinical and laboratory manifestations ranging from mild transaminitis to acute liver failure (ALF). Dengue ALF has a high mortality rate. The role of liver transplant (LT) in ALF is uncertain mainly due to co‐existing multiorgan dysfunction and the risk of re‐infection as a consequence of post‐transplant immunosuppression. Here, we report the first paediatric living donor auxiliary orthotopic LT in an adolescent boy who developed ALF due to dengue. LT for ALF associated with severe dengue may be an option for patients with isolated liver involvement not responding to standard medical management.
Exploring causal correlations between inflammatory cytokines and intervertebral disc degeneration: A Mendelian randomization

Published: July 2024

AbstractBackgroundInflammatory cytokines have been reported to be related to intervertebral disc degeneration (IVDD) in several previous studies. However, it remains unclear about the causal relationship between inflammatory cytokines and IVDD. This study employs Mendelian randomization (MR) to analyze the causal link between inflammatory cytokines and the risk of IVDD.MethodWe used genetic variants associated with inflammatory cytokines from a meta‐analysis of genome‐wide association study (GWAS) in 8293 Finns as instrumental variables and IVDD data were sourced from the FinnGen consortium. The main analytical approach utilized Inverse‐Variance Weighting (IVW) with random effects to assess the causal relationship. Additionally, complementary methods such as MR‐Egger, weighted median, simple mode, weighted mode, and MR pleiotropy residual sum and outlier were employed to enhance the robustness of the final results.ResultWe found interferon‐gamma (IFN‐γ, p = 2.14 × 10–6, OR = 0.870, 95% CI = 0.821–0.921), interleukin‐1 beta (IL‐1b, p = 0.012, OR = 0.951, 95% CI = 0.914–0.989), interleukin‐4 (IL‐4, p = 0.034, OR = 0.946, 95% CI = 0.899–0.996), interleukin‐18 (IL‐18, p = 0.028, OR = 0.964, 95% CI = 0.934–0.996), granulocyte colony‐stimulating factor (GCSF, p = 0.010, OR = 0.919, 95% CI = 0.861–0.980), and Stromal cell‐derived factor 1a (SDF1a, p = 0.014, OR = 1.072, 95% CI = 1.014–1.134) were causally associated with risk of IVDD.ConclusionOur MR analyses found a potential causal relationship between six inflammation cytokines (IFN‐γ, IL‐1b, IL‐4, IL‐18, SDF1a, and GCSF) and altered IVDD risk.
Financing decisions of third‐party remanufacturers with different co‐opetition modes: The impact of blockchain adoption
Authors: Ma Peng , Li Junmei , Xu Henry , Chen Mingjun 
Published: July 2024

AbstractThe third‐party remanufacturer (TPR) can cooperate with the original equipment manufacturer (OEM) and remanufactured products are sold by the OEM (i.e., the cooperation mode). The TPR can also sell remanufactured products individually to compete with the OEM's new products (i.e., the competition mode). Considering the issue of false information in remanufacturing supply chains and the TPR's limited capital, we build game models with blockchain to explore the TPR's optimal financing strategies under different co‐opetition mode selections. We find that a high blockchain usage prompts the TPR to finance from the OEM in the competition mode, while a low blockchain usage motivates the TPR to choose the cooperation mode and opt for a bank credit. Besides, we also find that the difference between the TPR's optimal profits of cooperation and competition modes increases with the interest rate.

AbstractBackgroundThe glymphatic clearance pathway is a waste clearance system that allows for removal of soluble proteins such as amyloid β (Aβ) from the brain. Higher Aβ levels are associated with cognitive dysfunction in Parkinson's disease (PD). Diffusion tensor imaging‐along the perivascular space (DTI‐ALPS) is an imaging measure proposed to indirectly measure glymphatic function.ObjectivesEvaluate differences in DTI‐ALPS‐index between PD and healthy controls (HC) and characterize relationships between this proposed measure of glymphatic clearance, cognition, and disease severity in PD.MethodsPD (n = 32) and HC (n = 23) participants underwent brain imaging to assess DTI‐ALPS. PD participants were classified as PD‐normal cognition (PD‐NC; n = 20) or PD‐mild cognitive impairment (PD‐MCI; n = 12) based on a Level II comprehensive cognitive assessment. A subgroup of PD participants (n = 21) returned for annual assessments for up to 4 years after baseline. Longitudinal outcomes included changes in performance on the comprehensive cognitive assessment and changes in the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS‐UPDRS).ResultsPD participants had lower DTI‐ALPS‐index compared to HC. PD participants classified as PD‐MCI had significantly lower DTI‐ALPS‐index compared to PD‐NC. Lower DTI‐ALPS‐index at baseline was associated with longitudinal cognitive decline and worse longitudinal disease severity.ConclusionsGlymphatic clearance, as measured with DTI‐ALPS, has potential to serve as a marker of longitudinal disease progression. Interventions targeting glymphatic function should be explored for potential to slow cognitive decline in PD. © 2024 International Parkinson and Movement Disorder Society.
Polyolefin elastomer/cyclic olefin copolymer/multi‐walled carbon nanotubes nanocomposites: Rheological, morphological, electrical and mechanical study
Authors: Saadatmand‐Navaran Mehran , Azizi Hamed , Ahmadjo Saeid 
Published: July 2024

AbstractThe subject of this research is a relatively detailed investigation of the rheological, morphological and electrical properties of nanocomposites based on polyolefin elastomer (POE), cyclic olefin copolymer (COC) and multi‐walled carbon nanotubes (MWCNTs). To formulate a mixture of two polymers (COC and POE), the melt mixing method was used and their morphology was studied by SEM technique and it was found that the morphology is of co‐continuous type. When the weight percentage ratio of COC was between 40 and 60, the desired morphology (co‐continuous) appeared. Interfacial tension calculations and TEM images proved that the nanotube particles were stabilized both within the phase of POE as well as at the interface of the two polymer phases. The rheological behavior was analyzed for composite samples containing 0–3 wt % MWCNT. The electrical and rheological percolation thresholds appeared at 1 and a 0.5 percent by weight of nanotube particles, respectively, which may be better to consider as related to the phenomenon of dual percolation. The highest conductivity was obtained for the nanocomposite containing 3% MWCNT. The results of mechanical tests also showed a strong upward trend of properties due to the addition of nanotube.Highlights
The effect of COC content on the morphology of POE/COC blend was investigated.
The Morphology for the POE/COC blend at low COC content was droplet‐matrix type.
MWCNT has a greater tendency to be in the POE phase than COC.
Rheological behavior strongly depended on the amount of nanotube particles.
The highest conductivity was obtained for the sample containing 3% MWCNT.
