Published: June 2023

AbstractObjectiveTo assess the associations between hepatitis B and C in women aged 15–49 years and neonatal preterm birth in high‐income countries (HICs).MethodsThis ecological study collected hepatitis B and C prevalence data in women aged 15–49 years and age‐standardized incidence rates (ASIRs) of neonatal preterm birth in HICs in 1990–2019 from the Global Burden of Disease study. Estimated annual percentage changes (EAPCs) in hepatitis B and C prevalence and ASIRs of neonatal preterm birth were calculated to quantify their temporal trends. Pearson correlation tests and generalized additive mixed models were used to estimate the associations between hepatitis B and C prevalence and ASIR of neonatal preterm birth.ResultsAmong women aged 15–49 years in HICs, hepatitis B prevalence increased only in the Northern Mariana Islands (EAPC, 0.16 [95% confidence interval (CI), 0.05–0.27]) and the United Kingdom (EAPC, 0.08 [95% CI, 0.04–0.12]) and hepatitis C prevalence increased in more than 20% of HICs in 1990–2019, with the largest increase in Belgium (EAPC, 1.00 [95% CI, 0.65–1.35]). Nearly 80% of HICs showed an increasing trend in ASIR of neonatal preterm birth in 1990–2019, with the largest increase in Greece (EAPC, 3.91 [95% CI, 3.65–4.18]). A positive association between hepatitis C prevalence in women aged 15–49 years and ASIR of neonatal preterm birth was observed in Pearson correlation tests and generalized additive mixed models (P ≤ 0.01).ConclusionASIR of neonatal preterm birth was associated with hepatitis C prevalence in women aged 15–49 years in HICs. Universal screening for hepatitis C virus is recommended at least once for women of reproductive age and during each pregnancy.

Published: June 2023

AbstractThe real‐time embedded system is a computer‐based special‐purpose intelligent computer system that meets the strict requirements of the application system for power consumption. With the development of the Internet era, people are increasingly using the Internet to obtain relevant information, while traditional data collection mainly relies on manual operations. Therefore, the collection, storage and transmission of track and field training information based on existing equipment and databases has become a research hotspot. Based on wireless medical sensor network, this paper proposes an efficient track and field training information collection and feedback system communication protocol for real‐time transmission of various data of track and field athletes, and a real‐time embedded system for data collection and storage. Through research and analysis, it is found that the collection and feedback of track and field training information based on wireless medical sensor network can improve the accuracy of collection by 8.625. This shows that the collection and feedback of sports training information based on wireless medical sensor network is feasible.

AbstractThis study aimed to explore the effect of myricitrin on osteoblast differentiation in mice immortalised bone marrow mesenchymal stem cells (imBMSCs). Additionally, ovariectomy (OVX) mice were employed to examine the effect of myricitrin on bone trabecular loss in vivo. The effect of myricitrin on the proliferation of imBMSCs was evaluated using a cell counting kit‐8 assay. Alizarin red staining, alkaline phosphatase staining were performed to elucidate osteogenesis. Furthermore, qRT‐PCR and western blot determined the expression of osteo‐specific genes and proteins. To screen for candidate targets, mRNA transcriptome genes were sequenced using bioinformatics analyses. Western blot and molecular docking analysis were used to examine target signalling markers. Moreover, rescue experiments were used to confirm the effect of myricitrin on the osteogenic differentiation of imBMSCs. OVX mice were also used to estimate the delay capability of myricitrin on bone trabecular loss in vivo using western blot, micro‐CT, tartaric acid phosphatase (Trap) staining, haematoxylin and eosin staining, Masson staining and immunochemistry. In vitro, myricitrin significantly enhanced osteo‐specific genes and protein expression and calcium deposition. Moreover, mRNA transcriptome gene sequencing and molecular docking analysis revealed that this enhancement was accompanied by an upregulation of the PI3K/AKT signalling pathway. Furthermore, copanlisib, a PI3K inhibitor, partially reversed the osteogenesis promotion induced by myricitrin. In vivo, western blot, micro‐CT, hematoxylin and eosin staining, Masson staining, Trap staining and immunochemistry revealed that bone trabecular loss rate was significantly alleviated in the myricitrin low‐ and high‐dose groups, with an increased expression of osteopontin, osteoprotegerin, p‐PI3K and p‐AKT compared to the OVX group. Myricitrin enhances imBMSC osteoblast differentiation and attenuate bone mass loss partly through the upregulation of the PI3K/AKT signalling pathway. Thus, myricitrin has therapeutic potential as an antiosteoporosis drug.

Published: June 2023

AbstractBACKGROUNDFood waste (FW) is easily acidified to produce acid inhibition, which limits the treatment efficiency of anaerobic digestion (AD). To improve the AD efficiency of FW, two‐stage anaerobic digestion (TSAD) technique was used to test the effect of food‐to‐microorganism (F/M) ratio on hydrogen production and the effect of Tween 80 addition on methane production. Changes in volatile fatty acids during FW TSAD were analyzed. Furthermore, the energy recovery of different TSAD conditions was compared.RESULTSUnder the condition of F/M = 10, hydrogen production of FW was the highest (102.79 mL g−1 volatile solids (VS)). In the methanogenesis stage of FW, the methane production of different conditions was 351.97–407.11 mL g−1 VS. Kinetic analysis showed that the hydrogen production could be increased by appropriately increasing the F/M ratios, and the time required to reach 90% methane production (t90) in the methanogenesis stage could be shortened by adding Tween 80. Analysis of energy recovery showed that the energy yield of TSAD was 13.01–15.68 kJ g−1 VS, and the average daily energy recovery of hydrogen production stage F/M = 10, methane production stage with 0.1% Tween 80 (A‐10 and M‐10 T) were the highest at t90, which was 9.23 and 4.60 kJ d−1.CONCLUSIONF/M ratio affects hydrogen production, and a suitable F/M ratio can improve the hydrogen production of the TSAD of FW. The addition of Tween 80 can shorten the t90 of the methanogenesis stage. Analysis of energy recovery calculation showed that A‐10 + M‐10 T was more economically rational for TSAD. © 2023 Society of Chemical Industry.

Authors: Güzel Kaya Gülcihan 
Published: June 2023

AbstractBackgroundGreenhouse gases, especially CO2, are primary factors for global warming and CO2 emissions continue to increase annually. Many legislations and agreements have been made to decrease, or at least stabilize, CO2 concentrations in the atmosphere. Moreover, promising CO2 capture technologies, such as adsorption using solid sorbents, have been developed and shown high CO2 adsorption capacity.ResultsVolcanic tuff, a natural pozzolanic material, was evaluated as a solid CO2 adsorbent in this study. Following pre‐treatment of the volcanic tuff with HCl solution, CO2 adsorption experiments were conducted by thermogravimetric analysis (TGA). Diamine functionalization of the volcanic tuff was carried out using amine based compounds with different chain lengths, including ethylenediamine, 1,4‐diaminobutane and 1,6‐diaminohexane. The CO2 adsorption capacity of the volcanic tuff was significantly enhanced in the presence of 1,6‐diaminohexane. Maximum CO2 adsorption capacity was determined to be 42.94 mg g−1 with 70 wt% 1,6‐diaminohexane loading. The CO2 adsorption capacity of the 1,6‐diaminohexane functionalized volcanic tuff decreased with increasing temperature, which was an indication of exothermic adsorption. Adsorption–desorption cycles revealed that the 1,6‐diaminohexane functionalized volcanic tuff was a reusable CO2 adsorbent with high stability.ConclusionThe results show that the low cost, eco‐friendly, and highly stable diamine functionalized volcanic tuff can be considered a promising adsorbent for CO2 capture. © 2023 Society of Chemical Industry (SCI).

AbstractTargeted screening programs for individuals with an increased risk for cancer have become increasingly available. Patients with multiple endocrine neoplasia (MEN), rare genetic conditions associated with the development of tumors in the endocrine glands, undergo intensive surveillance from an early age. Quantitative research has shown that patients with MEN experience fear of disease occurrence in themselves and their family members. However, little is known about the role that intensive, lifelong screening plays in the lives of individuals. This study investigates the lived experiences of patients with MEN undergoing regular tumor screening through an interpretative phenomenological analysis of interviews with 12 patients with MEN1, MEN2A, or MEN2B syndrome. Four experiential group themes are identified: coming to the foreground/fading into the background, relating to uncertainty, experiencing control, and familial context. Screening is characterized as an ambiguous experience that brings MEN to the foreground and may both exacerbate MEN‐related uncertainty as well as provide a sense of control over the disease. The experience of undergoing screening is strongly influenced by the familial context, as participants care for and are cared for by family members and understand their disease through familial experiences. Good care according to patients with MEN includes providing family‐centered care, addressing the impact on daily functioning and the meaning of illness, support in the interpretation of physical complaints, facilitation of patient experiences of control, and careful attunement to patient needs within a good doctor–patient relationship.

Published: June 2023

AbstractBACKGROUNDPortulaca oleracea has served as food and folk medicine in many parts of the world for thousands of years. Portulaca oleracea extract (POE) was prepared from fresh plants. This study aims to evaluate the antibacterial diarrhea effect and explore the possible mechanism.RESULTSPOE was effective in reducing diarrhea rate, improving intestinal tissue, and reducing cytokines concentrations of interleukin (IL)‐6, IL‐10, IL‐12 p40 and TNF‐α in blood. Besides, the result of histological observation showed that the mucus layer thickness and crypt length in the POE‐treated group was higher than that in the model group. The POE could significantly upregulate the protein expression of MUC2, occludin and ZO‐1. 16S rRNA sequencing analysis showed that Parabacteroides, Clostridium and Muribaculaceae may be the key functional microflora of POE. The non‐targeted metabolomics also suggested that the antibacterial diarrheal effects of P. oleracea may be attributed to the regulation of amino acid metabolism and composition of the gut microbiota.CONCLUSIONPortulaca oleracea has definite clinical efficacy against bacterial diarrhea and anti‐inflammatory effects. Its regulation of gut microbiota and fecal metabolism may account for its antibacterial diarrhea and anti‐inflammatory effects. © 2023 Society of Chemical Industry.

Published: June 2023

AbstractPursuing higher topological charge—larger angular indices m of high‐order Laguerre–Gaussian (LG) beams—is not only important for frontier applications like optical/quantum communication, optical tweezers, and super‐resolution imaging, but also involves a novel laser cavity and beam dynamics. Active methods to directly generate high‐order‐mode vortex beams from a laser cavity have excellent power handling and conversion efficiency, but struggle to achieve hundred‐level ultra‐high‐order LG modes. Here, the generation of ultra‐high‐order LG beams with m beyond 300 is demonstrated, utilizing the spherical aberration of a lens in the cavity of a simple end‐pumped Nd:YVO4 laser at 1064 nm. LG0,±m modes with m up to 317, selectable across a large range, are generated. With a simple model, how the mode selection relates to the cavity parameters is explained, and it is predicted that even higher order mode output can be expected by appropriate management of the elements’ aperture and laser gain. The approach provides a simple and flexible method to convert a wide range of lasers to generate ultra‐high‐order LG modes.

AbstractCounterfeited biomedical products result in significant economic losses and pose a public health hazard for over a million people yearly. Hydrogels, a class of biomedical products, are being investigated as alternatives to conventional biomedical products and are equally susceptible to counterfeiting. Here, a biocompatible, physically unclonable function (BPUF) to verify the authenticity of therapeutically relevant hydrogels are developed. The principle of BPUF relies on the self‐assembly of tyrosine into fibril‐like structures which are incorporated into therapeutically relevant hydrogels resulting in their random dispersion. This unclonable arrangement leads to distinctive optical micrographs captured using an optical microscope. These optical micrographs are transformed into a unique security code through cryptographic techniques which are then used to authenticate the hydrogel. The temporal stability of the BPUFs are demonstrated and additionally, exploit the dissolution propensity of the structures upon exposure to an adulterant to identify the tampering of the hydrogel. Finally, a platform to demonstrate the translational potential of this technology in validating and detecting tampering of therapeutically relevant hydrogels is developed. The potential of BPUFs to combat hydrogel counterfeiting is exemplified by its simplicity in production, ease of use, biocompatibility, and cost‐effectiveness.

AbstractSilane modification is a simple and cost‐effective tool to modify existing biomaterials for tissue engineering applications. Aminosilane layer deposition has previously been shown to control NG108‐15 neuronal cell and primary Schwann cell adhesion and differentiation by controlling deposition of ─NH2 groups at the submicron scale across the entirety of a surface by varying silane chain length. This is the first study toreport depositing 11‐aminoundecyltriethoxysilane (CL11) onto aligned Polycaprolactone (PCL) scaffolds for peripheral nerve regeneration. Fibers are manufactured via electrospinning and characterized using water contact angle measurements, atomic force microscopy (AFM), and X‐ray photoelectron spectroscopy (XPS). Confirmed modified fibers are investigated using in vitro cell culture of NG108‐15 neuronal cells and primary Schwann cells to determine cell viability, cell differentiation, and phenotype. CL11‐modified fibers significantly support NG108‐15 neuronal cell and Schwann cell viability. NG108‐15 neuronal cell differentiation maintains Schwann cell phenotype compared to unmodified PCL fiber scaffolds. 3D ex vivo culture of Dorsal root ganglion explants (DRGs) confirms further Schwann cell migration and longer neurite outgrowth from DRG explants cultured on CL11 fiber scaffolds compared to unmodified scaffolds. Thus, a reproducible and cost‐effective tool is reported to modify biomaterials with functional amine groups that can significantly improve nerve guidance devices and enhance nerve regeneration.

We show that the normalized system of root vectors of the operator is a Bari basis in if and only if the unperturbed operator is self‐adjoint. We also give explicit conditions for this in terms of coefficients in the boundary conditions. The Bari basis criterion is a consequence of our more general result: Let , , boundary conditions be strictly regular, and let be the sequence biorthogonal to the normalized system of root vectors of the operator . Then,

Factorization in Fourier restriction theory and near extremizers
Authors: Buschenhenke Stefan 
Published: June 2023

AbstractIn Fourier restriction theory, abstract so‐called Maurey–Nikishin–Pisier factorization has often been used as a convenient off‐the‐shelf means to prove certain factorizations of the Fourier restriction operator. We give an alternative approach to such factorizations in Fourier restriction theory. Based on an induction‐on‐scales argument, our comparably simple method applies to any compact quadratic surface, in particular compact parts of the paraboloid and the hyperbolic paraboloid. This is achieved by constructing near extremizers with big “mass,” which itself might be of interest.

Asking your phone or a frontline employee? The influence of in‐store information source on choice overload, responsibility, and confidence among young consumers

Published: June 2023

AbstractConsumers frequently use mobile phones in a store to search for external information as an alternative to consulting with frontline employees. Mobile phone usage is especially prevalent among young consumers. Drawing on qualitative study results and existing literature, we conceptualize the effects of different in‐store information sources on choice overload, responsibility, and confidence among young consumers, as well as the moderating role of product category knowledge. A field experiment suggests that when knowledge is low, consulting with frontline employees (vs. mobile phone) leads to lower choice overload and, consequently, increases choice confidence. When knowledge is high, these beneficial effects are attenuated. At the same time, young consumers perceive greater choice responsibility when their phone is the information source; however, this does not influence choice confidence. This work contributes to extant literature by extending the knowledge of customer experience at the point of sale, the role of technology usage in in‐store retailing, and the role of frontline employees as an information source. It also provides managerial implications for retailers by highlighting the importance of providing an opportunity for an in‐person frontline employee interaction especially when customers have low product category knowledge.
Photoresponsive Spiropyran and DEGMA‐Based Copolymers with Photo‐Switchable Glass Transition Temperatures
Authors: Pruthi Vaishali , Akae Yosuke , Théato Patrick 
Published: June 2023

AbstractHerein, novel photoresponsive spiropyran (SP)‐based P(DEGMA‐co‐SpMA) copolymers with variable percentages of SP fractions are synthesized. The SP group present in these polymers exhibited the abilities of reversible photoisomerism. Their photoresponsive, structural, and thermal properties have been investigated and compared using various characterization techniques. These light‐responsive copolymers are found to exhibit photoswitchable glass transition temperature (Tg), high thermal stability (Td > 250°C), instant photochromism as well as fluorescence upon exposure to UV light. It is demonstrated that the Tg of these synthesized polymers increased when irradiated with UV light (λ = 365 nm), as a consequence of the photoisomerization of incorporated SP groups into their merocyanine form. This increase in Tg is attributed to an increase in polarity and a decrease in the overall entropy of the polymeric system when it switches from the ring‐closed SP form (less‐ordered state) to the ring‐opened merocyanine form (more‐ordered state). Therefore, such polymers with a unique feature of phototunable glass transition temperatures provide the possibility to be integrated into functional materials for various photoresponsive applications.
