Published: March 2023

AbstractMaritime Antarctic King George Island (South Shetland Islands) has experienced rapid warming in recent decades, but the impacts on soil organic matter (SOM) decomposition remain ambiguous. Most vegetation cover is dominated by bryophytes (mosses), whereas a few vascular plants, such as Deschampsia antarctica and Colobanthus quitensis grow interspersed. Therefore, SOM is mainly enriched with carbohydrates and C‐alkyl, provided by mosses, which lack lignin as a precursor for aromatic compounds and humus formation. However, there is no clear answer to how substrate and temperature increase changes in Antarctic microbial respiration. We determined in what way SOM mineralization changes with temperature and substrate addition by characterizing the temperature sensitivity (Q10) of soil respiration in an open‐top chamber warming experiment. We hypothesized that: (a) cold‐tolerant microorganisms are well adapted to growing in maritime Antarctic soils (~ 0°C), so would not respond to low and moderate temperature increases because they undergo various metabolic mechanism adjustments until they experience increasing temperatures toward optimum growth (e.g., by enzyme production); and (b) cellulose, as a complex carbonaceous substrate of vegetated areas in Maritime Antarctic soils, activates microorganisms, increasing the Q10 of soil organic carbon (SOC) mineralization. Soils (5–10 cm) were sampled after four consecutive years of experimental warming for SOC composition, microbial community structure, and C mineralization at 4, 12, and 20°C with and without cellulose addition. Functional group chemoheterotrophs, represented mainly by Proteobacteria, decomposed more refractory SOC (aromatic compounds), as indicated by nuclear magnetic resonance (NMR) spectroscopy, in ambient plots than in warming plots where plants were growing. The C‐CO2 efflux from the incubation experiment remained stable below 12°C but sharply increased at 20°C. Q10 varied between 0.4 and 4 and was reduced at 20°C, whereas cellulose addition increased Q10. In conclusion, as confirmed during field studies in a climate scenario, cold‐tolerant microorganisms in maritime Antarctic soils were slightly affected by increasing temperature (e.g., 4–12°C), with reduced temperature sensitivity, as summarized in a conceptual model.

AbstractBackgroundHalyomorpha halys, (brown marmorated stink bug, BMSB), is a high‐concern invasive species causing severe damage to orchards in many countries outside its native Asian range. Management methods other than frequent sprays of broad‐spectrum insecticides are needed to restore integrated pest management (IPM) practices in orchards. Chitin synthesis inhibitors are usually regarded as desirable options in IPM programs because of lower toxicity to beneficial insects and non‐target organisms compared to neurotoxic insecticides. In this study, the activity of three chitin synthesis inhibitors (namely buprofezin, novaluron and triflumuron) was investigated on BMSB egg masses, third instars and adults by means of laboratory bioassays.ResultsNovaluron and to a lesser extent triflumuron were detrimental to BMSB nymphs exposed to residues on potted peach plants. Novaluron caused high mortality among early instars that emerged from sprayed egg masses. No significant differences were found between buprofezin and water control on eggs or third instars. When sprayed on BMSB adults, none of the chitin synthesis inhibitors affected survival, fecundity, or egg hatching.ConclusionGiven the activity on nymphs, but the lack of effects on adults, novaluron and triflumuron might be considered for field applications only as a tool in a wider management strategy along with other methods aimed at preventing the invasion of crops by BMSB adults. © 2023 Society of Chemical Industry.

AbstractGlucose‐dependent insulinotropic polypeptide (GIP) is a gastrointestinal hormone secreted by K cells in the small intestine and is considered an obesity‐promoting factor. In this study, we systematically investigated the anti‐obesity effects of intragastric safflower yellow (SY)/hydroxysafflor yellow A (HSYA) and the underlying mechanism for the first time. Our results showed that intragastric SY/HSYA, rather than an intraperitoneal injection, notably decreased serum GIP levels and GIP staining in the small intestine in diet‐induced obese (DIO) mice. Moreover, intragastric SY/HSYA was also first found to significantly suppress GIP receptor (GIPR) signaling in both the hypothalamus and subcutaneous White adipose tissue. Our study is the first to show that intragastric SY/HSYA obviously reduced food intake and body weight gain in leptin sensitivity experiments and decreased serum leptin levels in DIO mice. Further experiments demonstrated that SY treatment also significantly reduced leptin levels, whereas the inhibitory effect of SY on leptin levels was reversed by activating GIPR in 3 T3‐L1 adipocytes. In addition, intragastric SY/HSYA had already significantly reduced serum GIP levels and GIPR expression before the serum leptin levels were notably changed in high‐fat‐diet‐fed mice. These findings suggested that intragastric SY/HSYA may alleviate diet‐induced obesity in mice by ameliorating hyperleptinemia via dual inhibition of the GIP‐GIPR axis.

Authors: Strazzullo Serena , Moro Sérgio , Cricelli Livio 
Published: March 2023

AbstractThis article aims to assess the evolution of the literature on the link between Industry 4.0 and sustainable development. Through a systematic analysis of the literature, a sample of 234 documents was identified, published between 2011 and 2021. Given the large number of papers collected, the text mining approach was performed to analyze the sample of documents. In particular, the latent Dirichlet allocation model was adopted to group articles in different relevant topics starting from two dictionaries belonging to terms both in the domain of Industry 4.0 and in sustainability. As a result, 11 different topics have been identified that link these two domains. The results showed a strong predominance of Industry 4.0 compared to sustainability models that are very focused only on the environmental aspect. In conclusion, this study emphasizes future research potential by highlighting these existing research areas.

AbstractA significant quantity of hydrocarbons remains in the reservoir after production using primary and secondary techniques. Traditional recovery techniques produce about 33 % of the original oil in place. However, the utilization of chemicals such as surfactants and polymers facilitate the additional recovery of one‐third of this oil. Researchers are currently aiming at mixing surfactant and nanoparticles for their potential applications in petroleum industry. In this work, authors claimed to be the first to study usage of synthesized Mesoporous Silica Nanoparticles (MSN) with Sodium Dodecyl Sulphate (SDS) surfactant to understand its applicability in Chemical Enhanced Oil Recovery through evaluation of the surface tension & Interfacial tension, surfactant adsorption, contact angle, and core flooding experiments. Surface tension studies revealed a synergistic interaction between MSN and anionic surfactant molecules. With the introduction of 2500 ppm of anionic surfactant, the surface tension of deionized water reduces to 34.5 mN/m from 72.4 mN/m. The surface tension of the mixture was further lowered by ∼9.8 % with the addition of 300 ppm MSN. The Interfacial Tension results also showed the same trend. When 300 ppm of MSN was introduced, then IFT values decreases from 8.13 mN/m to 3.91 mN/m at 2500 ppm of anionic surfactant. Contact angle measurements after MSN injection went from 77.98° for SDS (2500 ppm) to 73.36°, 66.54°, and 41.95° for 100, 200, and 300 ppm of MSN, respectively. This demonstrates that the shift toward water‐wet behavior increased along with the MSN concentration. Additionally, adding 300 ppm of MSN lowered surfactant adsorption by ∼80 % at a surfactant concentration of 2500 ppm. Up to 72.27 % of the OOIP could be recovered using the chemical slug made of SDS surfactant, polymer, and MSN. The research data suggests that the MSN can increase the effectiveness of the chemical injection approach, which can be used to recover more oil.

AbstractAn efficient synthesis of 3‐methyl‐4‐(arylmethylene)isoxazol‐5(4H)‐ones are developed via cyclocondensation in 84–94 % yields starting from aromatic aldehydes, hydroxylamine with ethyl acetoacetate vitamin B1 is catalyzed under ultrasound radiation, and are characterized by HR‐MS, FT‐IR and 1H and 13C NMR spectroscopy. The reaction has simple operation, metal‐free catalysis, acid or base free catalysis. As a green catalyst, vitamin B1 is found to possess favorable catalytic activity and reusability for the condensation reaction. 5‐(2‐Hydroxy‐3‐methoxybenzylidene)‐3‐methylisoxazol‐5(4H)‐one as a metal ion fluorescent probe, has excellent selectivity to Sr2+ and exhibits obvious discoloration. Fe2+ quenches the fluorescence of the ligand 3‐methyl‐4‐(2,3,4‐trihydroxybenzylidene)isoxazol‐5(4H)‐one, and exhibits an obvious color change.

Published: March 2023

AbstractThe mechanisms involved in the oxidation of H2SO4 to peroxydisulfuric acid (H2S2O8) and H2O to O2 on WO3, SnO2, and their interface models were investigated using density functional theory. Regardless of the metal oxide, the free energy changes for the two proton‐coupled electron transfer (PCET) steps of the H2SO4 oxidation mechanism indicated that the first PCET is the rate‐limiting step that requires a greater energy input than the second one. Based on the free energy change in the rate‐limiting step, the WO3 anode with SnO2 was expected to produce electrochemically more H2S2O8 in an aqueous H2SO4 solution than SnO2 only without O2 evolution from H2O. We also experimentally confirmed that the Faraday efficiency of H2S2O8 production using the WO3 anode deposited on a F‐doped SnO2 conductive glass (FTO) with lower applied potential is superior to FTO only.

Published: March 2023

AbstractThe application of machine learning is demonstrated for rapid and accurate extraction of plasmonic particles cluster geometries from hyperspectral image data via a dual variational autoencoder (dual‐VAE). In this approach, the information is shared between the latent spaces of two VAEs acting on the particle shape data and spectral data, respectively, but enforcing a common encoding on the shape‐spectra pairs. It is shown that this approach can establish the relationship between the geometric characteristics of nanoparticles and their far‐field photonic responses, demonstrating that hyperspectral darkfield microscopy can be used to accurately predict the geometry (number of particles, arrangement) of a multiparticle assemblies below the diffraction limit in an automated fashion with high fidelity (for monomers (0.96), dimers (0.86), and trimers (0.58). This approach of building structure‐property relationships via shared encoding is universal and should have applications to a broader range of materials science and physics problems in imaging of both molecular and nanomaterial systems.
An Artificial Miniaturized Peroxidase for Signal Amplification in Lateral Flow Immunoassays
Authors: Renzi Emilia , Piper Andrew , Nastri Flavia , Merkoçi Arben , Lombardi Angela 
Published: March 2023

AbstractSignal amplification strategies are widely used for improving the sensitivity of lateral flow immunoassays (LFiAs). Herein, the artificial miniaturized peroxidase Fe(III)‐MimochromeVI*a (FeMC6*a), immobilized on gold nanoparticles (AuNPs), is used as a strategy to obtain catalytic signal amplification in sandwich immunoassays on lateral flow strips. The assay scheme uses AuNPs decorated with the mini‐peroxidase FeMC6*a and anti‐human‐IgG as a detection antibody (dAb), for the detection of human‐IgG, as a model analyte. Recognition of the analyte by the capture and detection antibodies is first evidenced by the appearance of a red color in the test line (TL), due to the accumulation of AuNPs. Subsequent addition of 3,3′,5,5′‐tetramethylbenzidine (TMB) induces an increase of the test line color, due to the TMB being converted into an insoluble colored product, catalyzed by FeMC6*a. This work shows that FeMC6*a acts as an efficient catalyst in paper, increasing the sensitivity of an LFiA up to four times with respect to a conventional LFiA. Furthermore, FeMC6*a achieves lower limits of detection that are found in control experiments where it is replaced with horseradish peroxidase (HRP), its natural counterpart. This study represents a significant proof‐of‐concept for the development of more sensitive LFiAs, for different analytes, based on properly designed artificial metalloenzymes.

Published: March 2023

AbstractFibrosarcomas occur as a mesenchymal tumour of malignant fibroblasts in a collagen background and are usually found in the female genital organs and rarely involve the skin. A 5‐year‐old female Holstein cow with a raised mass at the base of right ear was referred. On gross examination, the mass was approximately 13.00 × 10.00 × 7.00 cm in size. Finally, complete surgical removal was selected. The mass was encapsulated and the dermis was expanded by spindle‐shaped to polygonal neoplastic cells. These cells were arranged in interwoven pattern. Mitotic figures were infrequent. Masson's trichrome demonstrated the positive and blue staining of collagen. Immunohistochemically, the sections were uniformly positive for Vimentin and negative for Desmin, SMA and GFAP. A well‐differentiated fibrosarcoma was diagnosed based on histopathological features. Surgical excision is the treatment of choice for this neoplasm. In the present case, surgery was also performed successfully and no new growth of the mass was observed 4 months following the surgical procedures. To our knowledge, this is the first report of well‐differentiated fibrosarcoma in a Holstein cow.
Gender, Race, Culture and Identity at the Internal Border of Marriage Migration of Vietnamese Women in South Korea
Authors: Kneebone Susan 
Published: March 2023

AbstractIn this chapter I examine female marriage migration to South Korea from Vietnam as a transnational case study, to explain the discriminatory consequences of South Korea’s laws and policies on nationality which frame such migration as ‘a critical project for the nation-state’ (Toyota M. Citizensh Stud 12(1):1, 2008, p. 3). Through a socio-legal study, I demonstrate how notions of gender, race, culture and identity shape the internal border for marriage migrants from Vietnam, through laws and policies in South Korea. I argue that responses to female marriage migration from Vietnam has created vulnerabilities, through nationality laws, which are reinforced through instrumental policies on labour migration and commercial regulation of marriage. These laws and policies entrench the unequal position of Vietnamese marriage migrants in the transnational marriage migration ‘market’ to create ‘structural vulnerability’ through the power and structures of the state.
New q-Analogues of Van Hamme’s (E.2) Supercongruence and of a Supercongruence by Swisher
Authors: Guo Victor J. W. , Schlosser Michael J. 
Published: March 2023

AbstractIn this paper, a couple ofq-supercongruences for truncated basic hypergeometric series are proved, most of them modulo the cube of a cyclotomic polynomial. One of these results is a newq-analogue of the (E.2) supercongruence by Van Hamme, another one is a newq-analogue of a supercongruence by Swisher, while the other results are closely relatedq-supercongruences. The proofs make use of special cases of a very-well-poised$${}_6\phi _5$$6ϕ5summation. In addition, the proofs utilize the method of creative microscoping (which is a method recently introduced by the first author in collaboration with Wadim Zudilin), and the Chinese remainder theorem for coprime polynomials.
The bs5 allele of the susceptibility gene Bs5 of pepper (Capsicum annuum L.) encoding a natural deletion variant of a CYSTM protein conditions resistance to bacterial spot disease caused by Xanthomonas species

Abstract
Key message
The bs5 resistance gene against bacterial spot was identified by map-based cloning.

Abstract
The recessive bs5 gene of pepper (Capsicum annuum L.) conditions a non-hypersensitive resistance trait, characterized by a slightly swollen, pale green, photosynthetically active leaf tissue, following Xanthomonas euvesicatoria infection. The isolation of the bs5 gene by map-based cloning revealed that the bs5 protein was shorter by 2 amino acids as compared to the wild type Bs5 protein. The natural 2 amino acid deletion occurred in the cysteine-rich transmembrane domain of the tail-anchored (TA) protein, Ca_CYSTM1. The protein products of the wild type Bs5 and mutant bs5 genes were shown to be located in the cell membrane, indicating an unknown function in this membrane compartment. Successful infection of the Bs5 pepper lines was abolished by the 6 bp deletion in the TM encoding domain of the Ca_CYSTM1 gene in bs5 homozygotes, suggesting, that the resulting resistance might be explained by the lack of entry of the Xanthomonas specific effector molecules into the plant cells.
Tri‐modal Distribution of Trauma Deaths in a Resource‐Limited Setting: Perception Versus Reality

Published: March 2023

AbstractBackgroundAdvances in trauma care in high‐income countries have significantly reduced late deaths following trauma, challenging the classical trimodal pattern of trauma‐associated mortality. While studies from low and middle‐income countries have demonstrated that the trimodal pattern is still occurring in many regions, there is a lack of data from sub‐Saharan Africa evaluating the temporal epidemiology of trauma deaths.MethodsWe conducted a retrospective analysis of the trauma registry at Kamuzu Central Hospital in Lilongwe, Malawi, including all injured patients presenting to the emergency department (ED) from 2009 to 2021. Patients were compared based on timing of death relative to time of injury. We then used a modified Poisson regression model to identify adjusted predictors for early mortality compared to late mortality.ResultsCrude mortality of patients presenting to the ED in the study period was 2.4% (n = 4,096/165,324). Most patients experienced a pre‐hospital death (n = 2,330, 56.9%), followed by death in the ED (n = 619, 15.1%). Early death (pre‐hospital or ED) was associated with transportation by police (RR1.52, 95% CI 1.38, 1.68) or private vehicle (RR1.20, 95% CI 1.07, 1.31), vehicle‐related trauma (RR1.10, 95% CI 1.05, 1.14), and penetrating injury (RR1.11, 95% CI 1.04, 1.19). Ambulance transportation was associated with a 40% decrease in the risk of early death.ConclusionsAt a busy tertiary trauma center in Malawi, most trauma‐associated deaths occur within 48 h of injury, with most in the pre‐hospital setting. To improve clinical outcomes for trauma patients in this environment, substantial investment in pre‐hospital care is required through first‐responder training and EMS infrastructure.

Published: March 2023

AbstractThis study was designed to test the ability of some plant growth-promoting bacteria to adverse the effects of salinity on soybean growth. The effect ofBacillusMAP3 andEnterobacterDelta PSK, along withBradyrhizobium japonicumwas studied on soybean at two levels of NaCl salinization (50 and 100 mM). The physical growth parameters of bacterized soybean (21 days old), particularly plants co-inoculated withBradyrhizobium japonicum + EnterobacterDelta PSK, were significantly enhanced compared to control plants. The shoot length, leaf area, root length, and chlorophyll a content increased by 49.58%, 78.58%, 20.19%, and 57.35%, respectively, indicating the promoting activity of this bacterial combination. After 19 days following the onset of salinity stress, the retarded growth parameters in controls improved significantly due to bacterial treatments, especially byBradyrhizobium japonicum + EnterobacterDeltaPSK, which increased the values of all growth parameters significantly regardless of the salinity level. Additionally, electrolyte leakage, the amounts of malondialdehyde and hydrogen peroxide decreased considerably due to this combined bacterial treatment.Overall, the combination treatment ofEnterobacterDelta PSK and the original symbiontB. japonicumenhanced soybean growth under salt stress, indicating the ability ofEnterobacterDelta PSK to mitigate osmotic stress. The effect of this strain on soybean yield should be further evaluated to pave the way for its use as a biofertilizer along withB. japonicum,especially under salt stress.
