AbstractAdolescents faced with chronic stressors (e.g., financial instability, interpersonal violence) are at heightened risk for developing mental health problems, likely due in part to stressors that interfere with effective emotion regulation. Although mindfulness may help to act as a buffer against the deleterious effects of life stressors, a relatively untested assumption is that adolescents can maintain mindfulness during periods of stress. This paper explores this assumption by investigating the real‐time, dynamic relationships among life stressors, mindfulness, and emotion regulation difficulties among adolescents exposed to chronic stressors. Eighty‐one participants who were 10–18 years old (M = 14.33; SD = 2.20; 56% male; 57% Non‐Hispanic White) completed ecological momentary assessments (EMA) three times a day for 7 days and contributed a total of 1186 EMA reports. Multilevel structural equation modelling revealed that the presence (vs. absence) of stressors was associated with lower momentary mindfulness and greater momentary emotion regulation difficulties concurrently and prospectively. Stressors with greater severity were also concurrently, but not prospectively, associated with lower momentary mindfulness and greater momentary emotion regulation difficulties. Findings highlight that exposure to life stressors may degrade momentary mindfulness and emotion regulation. Given that mindfulness and emotion regulation are closely associated with mental health, these results also demonstrate one way that stressors may contribute to health disparities at the micro‐level. Going forward, it will be important to investigate methods of helping adolescents learn to maintain mindfulness and adaptive emotion regulation in the face of stressful events. This study was preregistered (NCT04927286).

Published: April 2024

AbstractBi/CeO2 (BC‐x) photocatalysts are successfully prepared by solvothermal loading Bi nanoparticles and Bi‐doped CeO2 derived by Ce‐MOF (Ce‐BTC). Formaldehyde gas (HCHO) and tetracycline hydrochloride (HTC) are used to evaluate the photocatalytic activity of the synthesized Bi/CeO2. For BC‐1000 photocatalyst, the degradation of HTC by 420 nm < λ < 780 nm light reaches 91.89% for 90 min, and HCHO by 350 nm < λ < 780 nm light reaches 94.66% for 120 min. The photocatalytic cycle experiments prove that BC‐1000 has good cyclic stability and repeatability. The results of photoluminescence spectra, fluorescence lifetime, photocurrent response, and electrochemical impedance spectroscopy showed that the SPR (Surface Plasmon Resonance) effect of Bi nanoparticles acted as a bridge and promoted electron transfer and enhanced the response‐ability of Bi/CeO2 to visible light. Bi‐doping produced more oxygen vacancies to provide adsorption sites for adsorbing oxygen and generated more ·O2− thus promoting photocatalytic reactions. The mechanism of photocatalytic degradation is analyzed in detail utilizing active free radical capture experiments and electron paramagnetic resonance (EPR) characterization. The experimental results indicate that ·O2− and h+ active free radicals significantly promote the degradation of pollutants.
Enhancing the Humidity Resistance of Triboelectric Nanogenerators: A Review
Authors: Zhang Jin , Boyer Cyrille , Zhang Y. X. 
Published: April 2024

AbstractTriboelectric nanogenerators (TENGs) are sustainable energy resources for powering electronic devices from miniature to large‐scale applications. However, their output performance and stability can deteriorate significantly when TENGs are exposed to moisture or humidity caused by the ambient environment or human physiological activities. This review provides an overview of the recent research advancements in enhancing the humidity resistance of TENGs. Various approaches have been reviewed including encapsulation techniques, surface modification of triboelectric materials to augment hydrophobicity or superhydrophobicity, the creation of fibrous architectures for effective moisture dissipation, leveraging water assistance for TENG performance enhancement, and other strategies like charge excitation. These research efforts contribute to the improvement of environmental adaptability and lead to expanded practical TENG applications both as energy harvesters and self‐powered sensors. The efficacy of these strategies and future challenges are also discussed to facilitate the continued development of resilient TENGs in high humidity environments.

AbstractBackgroundSodium‐glucose cotransporter‐2 (SGLT2) inhibitors are a novel class of anti‐hyperglycaemic agents.ObjectiveThis study aimed to evaluate the safety and the adjuvant glycaemic control effect of an SGLT2 inhibitor, DWP16001, in diabetic dogs receiving insulin treatment.MethodsNineteen diabetic dogs receiving insulin treatment (NPH, porcine lente and glargine insulin) were divided into two groups according to dosing frequency: DWP TOD group (n = 10) and DWP SID group (n = 9). In the DWP TOD group, 0.025 mg/kg of DWP16001 was administered once every 3 days, whereas, in the DWP SID group, 0.025 mg/kg of DWP16001 was administered once a day. Food intake was maintained during the trial period. Hypoglycaemia, ketoacidosis or unexpected life‐threatening reactions were assessed as adverse effects before and after DWP16001 administration. We compared insulin requirement reduction and blood glucose level control between two groups.ResultsNo specific adverse effects were observed during the clinical trial, and haematological parameter remained unchanged. Moreover, the fasting glucose levels and daily insulin dose in the DWP TOD group were lower than the pre‐administration values, but not significantly different for 8 weeks. Systolic blood pressure, fructosamine and insulin dose decreased significantly in the DWP SID group compared to the DWP TOD group at 8 weeks (p < 0.05) without affecting food consumption. Among these patients, 10 patients were monitored while receiving DWP16001 for 12 months (DWP TOD group n = 5, DWP SID group n = 5). The fasting glucose and fructosamine levels and daily insulin dose were reduced in both groups at 12 months compared with those before receiving DWP16001.ConclusionWhen DWP16001, an SGLT2 inhibitor, was supplied to dogs with type 1 diabetes, no adverse effects were observed, and it was confirmed that the administered insulin dose can be reduced in controlling blood glucose.
Market Power: Imperfect Competition and Strategic Behavior
Authors: Masters William A. , Finaret Amelia B. 
Published: April 2024

Abstract
Previous chapters used the principles of economics to build analytical models of individual choice and market outcomes designed to explain and predict changes in price, quantity and wellbeing in response to a change in circumstances. Each model shows how economic principles would apply to one type of situation, using prior knowledge of the context to show how supply, demand and trade respond to policy interventions that alter the distribution and level of wellbeing, first in the benchmark case of perfect competition and then with externalities that drive change in sustainability and equity. This chapter introduces the concept of market power, which is when a single seller or buyer controls the entire quantity bought and sold. In the first section we explore how firms acquire market power through economies of scale and product differentiation, how firms use market power to raise profits through quantity restriction or price discrimination and how governments respond in ways that alter market outcomes. In the second section we show how economic principles apply to strategic interactions, introducing game theory through the example of two people each of whom chooses between two options. That example shows how each person’s choices, when taking the other’s responses into account, lead to outcomes that depend on the payoff matrix of potential outcomes. The chapter provides many examples of how market power and strategic interactions play out in the food system, showing how economic analysis can help decision-makers reach higher levels of efficiency, equity and sustainability.
The Duality Theory of Fractional Calculus and a New Fractional Calculus of Variations Involving Left Operators Only
Authors: Torres Delfim F. M. 
Published: April 2024

AbstractThrough duality, it is possible to transform left fractional operators into right fractional operators and vice versa. In contrast to existing literature, we establish integration by parts formulas that exclusively involve either left or right operators. The emergence of these novel fractional integration by parts formulas inspires the introduction of a new calculus of variations, where only one type of fractional derivative (left or right) is present. This applies to both the problem formulation and the corresponding necessary optimality conditions. As a practical application, we present a new Lagrangian that relies solely on left-hand side fractional derivatives. The fractional variational principle derived from this Lagrangian leads us to the equation of motion for a dissipative/damped system.

The two faces of antibiotics: an overview of the effects of antibiotic residues in foodstuffs
Authors: Bacanlı Merve Güdül 
Published: April 2024

AbstractAntibiotics, which have been used for many years to treat infections, also play an important role in food contamination with antibiotic residues. There is also unnecessary use of antibiotics, particularly to increase production efficiency. Non-compliance with withdrawal periods and maximum residue limits (MRLs) for antibiotics used in food-producing animals results in undesirable events, such as allergic reactions, teratogenicity, carcinogenicity, changes in the microbiota and, in particular, antibiotic resistance. Therefore, it may be useful to avoid unnecessary use of antibiotics, to limit the use of antibiotics and to turn to alternatives that can be used instead of antibiotics. The aim of this review is to provide information on the undesirable effects of antibiotic residues in food-producing organisms and in the environment, their determination, and the precautions that can be taken.

AbstractThe prognostic and predictive role of specific gene mutations in Waldenström Macroglobulinemia (WM) is well-ascertained whereas the clinical impact of chromosome aberrations is far less known. Recent work has provided initial evidence for an adverse prognostic impact of some aberrations, such as del(6q), while other studies suggest a possible relationship between some clinical features (e.g. advanced age and/or inflammatory status) and specific cytogenetic abnormalities. To add to the still limited knowledge on WM cytogenetics and its clinical implications, we herein report our experience in a cohort of WM patients across 23 years. Based on our retrospective study, we found that abnormal karyotype was more represented in older patients and maintained a statistically significant independence from other molecular, clinical, and biological features related to WM. The presence and number of cytogenetic aberrations correlated with inferior overall and progression-free survival outcomes regardless of the type of single chromosome aberration. Our data suggests that the role of the altered karyotype deserves to be further clarified especially in elderly WM patients, in whom cytogenetic abnormalities and disease biology appear to be characterized by a higher degree of complexity.

Abstract
Purpose
Gastric cancer (GC) is among the leading causes of cancer mortality worldwide. The objective of this study was to investigate the association between dietary fiber intake and GC.

Methods
We pooled data from 11 population or hospital-based case–control studies included in the Stomach Cancer Pooling (StoP) Project, for a total of 4865 histologically confirmed cases and 10,626 controls. Intake of dietary fibers and other dietary factors was collected using food frequency questionnaires. We calculated the odds ratios (OR) and 95% confidence intervals (CI) of the association between dietary fiber intake and GC by using a multivariable logistic regression model adjusted for study site, sex, age, caloric intake, smoking, fruit and vegetable intake, and socioeconomic status. We conducted stratified analyses by these factors, as well as GC anatomical site and histological type.

Results
The OR of GC for an increase of one quartile of fiber intake was 0.91 (95% CI: 0.85, 0.97), that for the highest compared to the lowest quartile of dietary fiber intake was 0.72 (95% CI: 0.59, 0.88). Results were similar irrespective of anatomical site and histological type.

Conclusion
Our analysis supports the hypothesis that dietary fiber intake may exert a protective effect on GC.
Regulation of VEGF-A expression and VEGF-A-targeted therapy in malignant tumors
Authors: Kang Yan , Li Huiting , Liu Yiping , Li Zheng 
Published: April 2024

AbstractVascular endothelial growth factor A (VEGF-A), a highly conserved dimeric glycoprotein, is a key regulatory gene and a marker molecule of angiogenesis. The upregulation of VEGF-A facilitates the process of tumor vascularization, thereby fostering the initiation and progression of malignant neoplasms. Many genes can adjust the angiogenesis of tumors by changing the expression of VEGF-A. In addition, VEGF-A also exhibits immune regulatory properties, which directly or indirectly suppresses the antitumor activity of immune cells. The emergence of VEGF-A-targeted therapy alone or in rational combinations has revolutionized the treatment of various cancers. This review discusses how diverse mechanisms in various tumors regulate VEGF-A expression to promote tumor angiogenesis and the role of VEGF-A in tumor immune microenvironment. The application of drugs targeting VEGF-A in tumor therapy is also summarized including antibody molecule drugs and traditional Chinese medicine.

Published: April 2024

AbstractHybrid learning environments saw significant growth due to the COVID-19 pandemic but persist beyond it, one example is the telepresence classroom. This classroom allows the connection of two classrooms in distance locations into a singular one. The technology in a telepresence classroom includes a camera, multiple projectors, microphones, and speakers to emulate a single learning space despite the distance, potentially overcoming some of the challenges presented by hybrid settings. However, the telepresence classroom presents technological and logistical complexities for the teachers. Thus, it is essential to understand the impact on the teacher agency, as well as on the workload of both students and teachers. Therefore, two collaborative learning sessions were conducted, utilising the collaborative learning flow pattern (jigsaw) in the telepresence classroom. From these experiments, the teacher and students workload was measured using the NASA-TXL questionnaire and supplemented with the Epistemic Network Analysis model to pinpoint key actions impacting the workload. The teacher agency was also assessed with another questionnaire. Finally, an interview was conducted with the teacher to gather more insights regarding the workload and agency. Results revealed a teacher workload score of 65.33 and 67.33, while student averages stood at 49.03 and 58.65 on a 0-100 scale. The data collected also served to identify potential factors influencing the workload, such as available time or the need for increased effort. Potential factors affecting teacher agency, such as decision-making challenges and tool limitations, were also identified.
A comparison electrical characteristics of the Au/(pure-PVA)/n-Si and Au/(CdTe doped-PVA)/n-Si (MPS) type Schottky structures using I–V and C–V measurements

AbstractIn this study, both the Au/(pure-PVA)/n-Si (MPS-1) and Au/(CdTe:PVA)/n-Si (MPS-2) type Schottky diodes (SDs) were fabricated onto the same n-Si wafer in same conditions. After that, their electrical parameters were obtained from the current–voltage (I–V) and capacitance–voltage (C–V) measurements and compared to each other to determine the effect (CdTe:PVA) interlayer on the performance of MPS type SD. The saturation current (Is), ideality factor (n), rectification ratio (RR = Ifor./Irev.), zero-bias barrier height (ΦBo), and series/shunt resistances (Rs, Rsh) were derived utilizing I–V data. The values of Io, n, and ΦBo were found as 9.13 × 10–7 A, 11.07, 0.63 eV for MPS1 and 1.54 × 10–10 A, 3.97, 0.85 eV for MPS2, respectively. The C−2–V graphs were drawn for 0.7 MHz to obtain the doping concentration of donor atoms (ND), Fermi energy (EF), BH/(ΦB(C–V)), depletion layer width (WD), and maximum electric field (Em). The Nss − (Ec − Ess) profile for two SDs was produced from the I–V data by considering the voltage dependence of n and BH. The values of surface states (Nss) were changed between 4.8 × 1013 and 1.7 × 1014 eV−1 cm−2 for MPS1 and 5 × 1012 and 1.15 × 1013 eV−1 cm−2 for MPS2, respectively. All experimental results show that the (CdTe:PVA) interlayer significantly improved the quality of the MS type SDs rather than (pure-PVA) in terms of lower values of leakage/saturation current, n, Nss, and higher RR, BH, and Rsh when compared (pure-PVA) interlayer. The (CdTe:PVA) interlayer may be used instead of the conventional interlayer in the future.

Published: April 2024

AbstractHypothermia during obstetric spinal anaesthesia is a common and important problem, yet temperature monitoring is often not performed due to the lack of a suitable, cost-effective monitor. This study aimed to compare a noninvasive core temperature monitor with two readily available peripheral temperature monitors during obstetric spinal anaesthesia. We undertook a prospective observational study including elective and emergency caesarean deliveries, to determine the agreement between affordable reusable surface temperature monitors (Welch Allyn SureTemp® Plus oral thermometer and the Braun 3-in-1 No Touch infrared thermometer) and the Dräger T-core© (using dual-sensor heat flux technology), in detecting thermoregulatory changes during obstetric spinal anaesthesia. Predetermined clinically relevant limits of agreement (LOA) were set at ± 0.5 °C. We included 166 patients in our analysis. Hypothermia (heat flux temperature < 36 °C) occurred in 67% (95% CI 49 to 78%). There was poor agreement between devices. In the Bland-Altman analysis, LOA for the heat flux monitor vs. oral thermometer were 1.8 °C (CI 1.7 to 2.0 °C; bias 0.5 °C), for heat flux monitor vs. infrared thermometer LOA were 2.3 °C (CI 2.1 to 2.4 °C; bias 0.4 °C) and for infrared vs. oral thermometer, LOA were 2.0 °C (CI 1.9 to 2.2 °C; bias 0.1 °C). Error grid analysis highlighted a large amount of clinical disagreement between methods. While monitoring of core temperature during obstetric spinal anaesthesia is clinically important, agreement between monitors was below clinically acceptable limits. Future research with gold-standard temperature monitors and exploration of causes of sensor divergence is needed.
