AbstractBACKGROUNDVanadium‐doped manganese dioxide (V‐MnO2) was fabricated for effective photocatalytic degradation of ciprofloxacin (CIP) and moxifloxacin (MOXI) antibiotics under visible light. V‐MnO2 fabricated by simple redox method was characterized by spectrophotometry, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, X‐ray diffraction, zeta potential, dynamic light scattering (DLS), Fourier transform infrared spectroscopy and photoluminescence (PL) techniques.RESULTSDLS measured average particles size of 93.18 nm for MnO2, which reduced to 88 nm for V‐ MnO2 and zeta potential indicated −11.5 mV for MnO2 and 17.7 mV for 1% V‐MnO2. PL spectra of V‐MnO2 was suppressed as compared to MnO2 spectra, indicating a decrease in electron hole recombination and leading to increased photocatalytic activity of V‐MnO2. Band gap results revealed a successful decrease in band gap of MnO2 from 3.30 to 2.82 eV after doping with 1% V. Maximum degradation of CIP and MOXI achieved was 92% ± 2.98% and 79.5% ±2.15%, respectively, at pH 6. Optimum visible light irradiation of 180 and 300 min was calculated for CIP and MOXI, respectively. V‐MnO2 catalyst was recyclable for three cycles.CONCLUSIONV‐MnO2 catalyst was successfully applied to treatment of CIP and MOXI in spiked real water supply and sewage wastewater samples. Computational molecular models of CIP, MOXI, MnO2 and V‐MnO2 were built and optimized. Total energy values measured by a semi‐empirical method revealed that V‐MnO2 structure was less stable than MnO2, with weakened bonds between Mn atoms of MnO2 structure after doping of V ions. © 2022 Society of Chemical Industry (SCI).

AbstractWe aimed to explore the brain functional connectivity mechanism of attention cognitive impairment in children with nocturnal enuresis (NE). Children with NE often show attention cognitive deficit, but its brain mechanism remains unclear. Most previous studies have only focused on a single brain region, without involving the association among brain regions. In this study, 26 NE and 26 normal children were selected. Functional magnetic resonance imaging (fMRI) and integrated visual and auditory continuous performance test (IVA‐CPT) were performed. The 12 key brain regions of the dorsal attention network (DAN), default mode network (DMN) and ventral attention network (VAN) were selected as areas of interest, and 66 groups of functional connectivity (FC) were analysed among these 12 brain regions. The correlation between FC and IVA‐CPT in the two groups was analysed. The FC values showed that the groups with significant differences between NE and normal children were lFEF‐aMPFC, rFEF‐lIFG, rFEF‐rIPS and lAG‐VFC (P < 0.05), and the FC value of lAG‐VFC was positively correlated with the Full‐Scale Attention Quotient (FAQ). Our results showed that attention deficit in children with NE was associated with all three networks and was relative to the FC among the three attention networks. DAN was the brain network most related to attention cognition in children with NE, and most of the brain regions with abnormal connectivity in NE were related to the prefrontal lobe. The lAG was also an important brain region in attention impairment in NE.
Estimating impacts of logistics processes on online customer ratings: Consequences of providing technology‐enabled order tracking data to customers

Published: July 2022

AbstractRecent advances in logistics tracking technologies have enabled e‐commerce firms to both accurately track the shipments and obtain accurate estimates of delivery times. With customers constantly tracking the status of their orders, the effects of logistics processes on customers' evaluation of their online shopping experience are relatively unknown as academic literature provides little guidance. Drawing upon the expectation‐disconfirmation theory and attribution theory, and using a unique dataset assembled in collaboration with an e‐commerce firm, we empirically investigate the effects of order processing and delivery times on online customer ratings. We also estimate the impact of positive deviation (i.e., early delivery) and negative deviation (i.e., late delivery) from the promised delivery date on online customer ratings and whether the impact of delivery status (early or late) depends on order cost and freight cost. Our empirical findings demonstrate that longer order processing and delivery times are associated with lower ratings. Our results also highlight that the late delivery of an order is negatively associated with ratings and that the order cost amplifies this effect. Furthermore, freight cost reduces both the negative effect of late delivery and the positive effect of early delivery on online ratings. Our results also indicate that there exist curvilinear relationships between online ratings and the number of days an online order is late or early. Specifically, the negative effect of a late delivery follows a convex‐shape curve such that its impact decreases as the number of days an online order is late increases. Likewise, the positive effect of an early delivery increases at a decreasing rate as the number of days an online order is early increases. Our supplementary analyses further account for potential endogeneity issues and corroborate our main results with additional empirical evidence obtained through alternative model specifications and estimation strategies. We present important theoretical implications and managerial takeaways from our findings.

Effect of Cationic Groups on the Selectivity of Ternary Antimicrobial Polymers
Authors: Pham Phuong , Oliver Susan , Nguyen Duong Thanh , Boyer Cyrille 
Published: July 2022

AbstractAntimicrobial polymers (AMPs) have emerged as a promising approach to combat multidrug‐resistant pathogens. Developed from binary polymers, which contain cationic and hydrophobic groups, ternary polymers are enhanced by adding neutral hydrophilic monomers to improve their biocompatibility. Cationic groups have attracted significant attention owing to their pivotal role in AMPs. Although many studies have investigated the effect of cationic groups on antimicrobial activity of binary AMPs, there is a lack of comprehensive and systematic evaluation for ternary AMPs. Therefore, a library of 31 statistical amphiphilic ternary polymers containing different cationic groups, including primary amine, guanidine, and sulfonium groups is prepared to investigate the impact of cationic groups on antimicrobial activity and biocompatibility. It is shown that the cationic balance appears to be a critical factor influencing polymers' antibacterial activity and selectivity. The results reveal that the polymers that have the ratio of the cationic groups ranging between 50% and 60%, coupled with a cationic/hydrophobic ratio in the range of [1.4–2] and an appropriate neutral hydrophilic/hydrophobic balance, exhibited the highest selectivity toward mammalian cells. This study elucidates a structure–property‐performance relationship for ternary AMPs, which contributes to the development of AMPs capable of selectively targeting gram‐negative pathogens.

ScopeHighland barley tea is a kind of caffeine‐free cereal tea. Previous studies have shown that it is rich in polyphenol flavonoids. Here, the effect of Highland barley tea polyphenols (HBP) on the production of advanced glycosylation end‐products and alleviate the skeletal muscle damage is systematically investigated.Methods and ResultsHBP effectively inhibits the formation of AGEs in vitro, and 12 phenolic compounds are identified. In addition, d‐galactose is used to construct a mouse senescence model and intervenes with different doses of HBP. It is found that high doses of HBP effectively inhibit AGEs in serum and flounder muscle species and increased muscle mass in flounder muscle; also, high doses of HBP increase the expression of the mitochondrial functional protein SIRT3 and decrease the expression of myasthenia‐related proteins. Furthermore, cellular experiments show that AGEs can significantly increase oxidative stress in skeletal muscle.ConclusionThese data indicate that the relationship between the biological activity and HBP properties is relevant since Highland barley can be a potential functional food to prevent AGEs‐mediated skeletal muscle damage.
The expression level of mir‐21‐3p in platelet‐rich plasma: A potential effective factor and predictive biomarker in recurrent implantation failure

Published: July 2022

AbstractRecurrent implantation failure (RIF) is the most important complication associated with in vitro fertilization (IVF). Despite the good quality of the transferred embryo, the success rate is rather disappointing. Therefore, predictive biomarkers for implantation are critical to making decisions about transferring high‐quality embryos or cryopreserving them for cycles with a higher chance of implantation. Recently, intrauterine infusion of autologous platelet‐rich plasma (PRP) has been proposed to increase the endometrial receptivity in RIF patients. PRP is rich in both growth factors and microRNAs (miRNAs). We investigated the possible association of mir‐21‐3p, mir‐21‐5p, mir‐494‐3p, mir‐145‐5p, and insulin‐like growth factor‐I (IGF‐I) levels in PRP and platelet‐poor plasma (PPP) samples with the pregnancy outcomes in RIF patients. The miRNA expression level and IGF‐I concentration were assessed using real‐time PCR and chemiluminescence methods respectively. Mir‐21‐3p was upregulated in PRP samples of the pregnant group in comparison to the nonpregnant group. There was no difference in the expression of mir‐21‐3p in PPP samples of these groups. The concentration of IGF‐I was higher in PRP and PPP samples of the nonpregnant in comparison to the pregnant group. Receiver‐operating characteristic curve analysis showed that mir‐21‐3p can be a valuable biomarker for the prediction of pregnancy chance in RIF patients treated with PRP.
Constitutive anamnesis model (CAM) for fine‐grained soils

Published: July 2022

AbstractMainly, two divisions are encountered in the literature regarding constitutive models: elasto‐plasticity and hypoplasticity. In addition, barodesy and the framework of generalized plasticity are used. The main disadvantage of nearly all models is the failure to reproduce the mechanical behaviour under cyclic loading without restrictions. A model which deals neither with the true hypoplastic nor the true elasto‐plastic approach will be proposed herein. Moreover, it combines and establishes the unification of both frameworks and it can be assigned to both of them. It introduces a so called historiotropic surface, responsible for the memory of the soil, but no consistency condition. It also introduces a hypoplastic strain rate, but incorporating the distance to the new surface for its intensity and the back stress tensor. Hence, both the intergranular strain as well as the fabric‐dilatancy tensor are omitted, even though the eight‐shaped stress hysteresis at cyclic mobility is well reproduced.

Published: July 2022

AbstractObjectiveChildhood obesity is a public health concern that often worsens with age. Although several risk factors at the child and maternal levels have been identified in cross‐sectional studies, less is known about their long‐term contribution to racial/ethnic disparities in childhood obesity. This study examines child‐ and maternal‐level factors associated with the growth trajectories of White, Black, and Latino children.MethodsGroup‐based trajectory models were used to identify BMI z score trajectories from birth to 9 years of age among White, Black, and Latino children. The associations of child‐ and maternal‐level factors with the trajectory group identified as at risk for obesity were examined using adjusted logistic regression analysis, stratified by race/ethnicity.ResultsAmong White children, fast‐food consumption (odds ratio [OR] = 1.66; 95% CI: 1.09‐2.52) was associated with higher odds of following an at‐risk trajectory. Among Black and Latino children, prepregnancy BMI was associated with following an at‐risk trajectory (OR = 1.05; 95% CI: 1.03‐1.08 for Black children, and OR = 1.12; 95% CI: 1.07‐1.17 for Latino children).ConclusionsThese findings showed racial/ethnic differences in the risk factors that influence the likelihood of obesity during childhood. Further research is needed to identify modifiable racial/ethnic specific risk factors to guide obesity‐prevention interventions.

Published: July 2022

AbstractIntroductionCarpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome. Although prior studies have explored the anatomic changes of the median nerve and carpal arch with different wrist deviations and positionings, the change in safe zone distance between the median nerve and ulnar artery with ulnar or radial wrist deviations has not been adequately investigated.ObjectiveTo identify the optimal wrist positioning that increases the safe zone distance between the median nerve and ulnar artery using ultrasound in patients with CTS.DesignRetrospective cohort study.SettingQuaternary medical center multidisciplinary outpatient hand clinic.ParticipantsTwenty five patients (41 wrists) with clinical CTS who received an electrodiagnostic study (EDX) to evaluate CTS within 1 year prior to enrollment.InterventionsUltrasound‐identified safe zone distance measurements were obtained in each patient between the ulnar aspect of the median nerve and the radial aspect of the ulnar artery with the wrist in neutral radial‐ulnar deviation as well as in passive ulnar and radial deviation.Main Outcome MeasureThe ultrasound‐identified safe zone distance with the wrist in each of the three positions.ResultsThe interstructural safe zone distance was significantly greater when measured in the ulnarly deviated position (1.08 cm) compared with either the neutral (0.61cm, p < .001) or radially deviated positions (0.52 cm, p < .001). Interstructural safe zone distance did not differ between those with normal, mild, moderate, or severe classifications of pathology, or between dominant and nondominant limbs.ConclusionThis study demonstrates that the ultrasound‐measured interstructural safe zone distance was significantly greater in the ulnarly deviated position than in either the neutral position or radially deviated position. These findings may lead to improvement in the safety of ultrasound‐guided injections.

AbstractThe aim of this study is to explore the clinical efficacy of immediate breast reconstruction (IBR) using the latissimus dorsi muscular flap in Chinese breast cancer patients. The clinical data of 17 breast cancer patients who underwent IBR using the latissimus dorsi muscular flap between August 2013 and September 2021 at Affiliated Cancer Hospital of Nanjing Medical University were analyzed retrospectively. Harris scoring standard was used to evaluate the cosmetic effect. All the 17 cases were successfully treated. The median age was 43 years old (age range: 32–54 years old). In the clinical staging, the patients were mainly early and mid‐stage patients, with two cases in stage 0, 12 cases in stage II, and three cases in stage III. Postoperative pathology was predominantly invasive breast cancer (15/17), and two cases were carcinoma in situ. The median operation time was 300 min (range: 180–450 min) and only two patients developed complications. After 2–97 months of follow‐up, no patients had recurrence or metastasis. According to the Harris method, 9, 6, 2, and 0 cases were evaluated as “excellent”, “good”, “fair,” and “poor” respectively. The practical application of IBR using the latissimus dorsi muscular flap is a safe and feasible way to improve physical and mental health in breast cancer patients.
Characteristics of ionization behaviors of aminonitrotoluene isomers produced by atmospheric pressure chemical ionization
Authors: Choi He‐Ryun , Choi Sung‐Seen 
Published: July 2022

RationaleSix of the isomers of aminonitrotoluene (ANT) are 2‐amino‐3‐nitrotoluene (2A3NT), 2A4NT, 2A5NT, 2A6NT, 4A2NT, and 4A3NT. Some of them can be identified by chromatography and spectroscopy. Biochemical transformation of 2,4,6‐trinitrotoluene (TNT) and dinitrotoluenes (DNTs) is very complex and ANTs are decomposition products of TNT and DNTs.MethodsEach isomer in acetone was ionized using atmospheric pressure chemical ionization in positive and negative ion modes, and kinds and abundances of the product ions were analyzed. Energy‐minimized structures of the product ions and their energies were calculated to explain the analysis results.ResultsThe [M + H]+, [M + H + Acetone − H2O]+, and [M + H + Acetone]+ ions as positive product ions were detected, while [M − H]−, M•−, and [M + O2]•− ions as negative ones were observed. The order of the ionization efficiencies for the positive product ions was 4A3NT > 4A2NT > 2A4NT > 2A6NT > 2A5NT > 2A3NT, while that of the negative ones was 2A5NT > 2A3NT > 4A3NT > 2A4NT > 2A6NT > 4A2NT. Ion abundance ratios for 2A3NT and 2A5NT showed very similar trends, while those of 2A6NT and 4A2NT also showed similar trends. Differences in the ionization behaviors were explained using the heats of reaction.ConclusionsThe product ions were produced by ion–molecule reactions with the reactant ions of [2Acetone + H]+ and [Acetone + O2]•−. The [M + H + Acetone]+ ion was fragmented to produce [M + H]+ and [M + H + Acetone − H2O]+, while the [M + O2]•− ion was fragmented to generate the [M − H]− and M•− ions. Differences in the ionization behaviors of the ANTs can be used for their differentiation.

Published: July 2022

AbstractThe structure and properties of the carrier significantly affect the catalytic activity of the active centers for supported electrocatalysts. Therefore, elaborate design and regulation of the physicochemical properties of carbon carriers are essential to improve the activity and stability of the carbon‐supported ruthenium‐based catalysts. Herein, enlightened by the unique characteristics of coexisting sp2 and sp3 carbon nuclei in N‐doped carbon dots (NCDs), a hybrid structure of N‐doped carbon substrates featuring N‐doped sp2/sp3 carbon interfaces loaded with Ru nanoparticles (Ru/NCDs) is obtained. Spectroscopic analysis and density functional theory calculations illustrate that the interaction between Ru and NCDs effectively modulates the electronic structure of the active center Ru, and the formed N‐doped sp2/sp3 carbon interface lowers the energy barrier of the intermediates in hydrogen evolution reaction (HER) and balances the hydrogen adsorption and desorption and, thereby, greatly improves the activity of Ru/NCDs. Remarkably, Ru/NCDs exhibit excellent HER activity and stability in comparison to Pt/C, which merely requires overpotentials as low as 37 and 14 mV at 10 mA cm−2 in alkaline and acidic electrolytes, respectively. This finding will provide more thoughts about the influence of substrate properties on the catalytic activity and rational design of carbon‐loaded electrocatalysts.

Published: July 2022

AbstractIn this study, a novel biomaterial polyethyleneimine grafted H2O2‐oxidized starch nanocrystals (OSNCs‐PEI) is successfully prepared to remove hexavalent chromium (Cr(VI)) in the solution. The fourier transform infrared spectroscopy and energy dispersive X‐ray spectroscopy confirm that the hydroxyl groups on starch nanocrystals (SNCs) are oxidized to aldehyde groups, and PEI is successfully grafted on the OSNCs. When the pH is 3, the zeta potential of OSNCs‐0.1wt%PEI, OSNCs‐1.0wt%PEI, and OSNCs‐3.0wt%PEI reach the maximum value of +30.4, +43.2, and +46.3 mV, respectively. The effects of contact time, pH, initial concentration, and temperature on the adsorption behavior are investigated. The process of removing Cr(VI) from aqueous solution by OSNCs‐PEI is more suitable when pH is 3 and the adsorption time is 60 min. When the initial concentration of Cr(VI) is 1000 mg L–1, the adsorption capacity of Cr(VI) by OSNCs‐0.1wt%PEI, OSNCs‐1.0wt%PEI, and OSNCs‐3.0wt%PEI are up to 103.56, 173.91, and 184.35 mg g–1, respectively. The adsorption of Cr(VI) by OSNCs‐PEI follows the pseudo‐second‐order kinetic model and the adsorption experimental data fits well the Freundlich adsorption isotherm model. The adsorption of Cr(VI) by OSNCs‐PEI is a spontaneous and endothermic process.
