Authors: Phan Uyen Thuy Xuan , Tran Cuc Thuy Thi , Nguyen Nguyet Minh Thi 
Published: May 2024

AbstractFood safety has emerged as a critical concern in Vietnam, posing a significant threat to public health due to the prevalence of unsafe foods in the market. Among those most vulnerable to contaminated foods, low‐income individuals are significantly affected. This study aimed to investigate the perceptions of food safety among this demographic, utilizing qualitative and quantitative approaches, including focus groups, survey questionnaires, and behavioral experiments using steamed bun as a stimulus. Participants were generally from low‐income classes with certain variations in household monthly income. Results from focus groups and the survey highlighted that the factors influencing food purchases included perception of safety, sensory properties, and acceptable pricing. The behavioral experiment revealed that participants with lower incomes were more inclined to select foods containing unsafe chemicals. In conclusion, the study underscored the heightened vulnerability of low‐income individuals to unsafe foods, with their perception of food safety bounded by socioeconomic status.Practical ApplicationsThe study highlights the high risk of contaminated food consumption among low‐income individuals in Vietnam, intensified by economic struggles and heightened vulnerability to food insecurity. With this demographic relying on regulations for their health, urgent actions are needed. Governmental policymakers should focus on implementing food safety educational campaigns, promoting affordable and safe alternatives, and providing food aid to economically disadvantaged communities. Mandatory food safety training programs for street food vendors, food handlers, and small businesses, coupled with regular safety practice monitoring, can play a crucial role in mitigating serious consequences. In addition, the research methodologies employed in this study, especially the behavioral experiment approach, can serve as valuable tools for researchers in the field of consumer behavior, enabling them to attain valid and reliable results.
Constraint‐aware optimization model for plane truss structures via single‐agent gradient descent

Published: May 2024

AbstractThis study introduces the constraint‐aware optimization model (CAOM), a novel optimization framework designed to optimize the size, shape, and topology of plane truss structures simultaneously. Unlike traditional optimization models, which rely on gradient descent and frequently struggle with managing various constraints due to their dependence on a single optimization agent, CAOM effectively addresses this challenge. It does so by incorporating a variety of assistant modules along with the Adam optimizer, a variant of the gradient descent method. Uniquely, CAOM employs the leaky rectified linear unit (ReLU) activation function beyond its conventional use in neural networks, applying it as a mechanism to integrate constraints and losses seamlessly. The model's effectiveness was validated through two numerical examples and a practical application, demonstrating that CAOM can reduce structural weight by up to 84% compared to unoptimized designs while fully adhering to structural, dimensional, and moveable constraints. Furthermore, the study found that while shape optimization plays a key role for stiffness‐governed structures, size optimization is crucial for strength‐governed structures. Optimizing size, shape, and topology together consistently leads to the most weight‐efficient designs. This emphasizes the significance of a holistic approach in the optimization processes.
Nutrition and exercise: Cornerstones of health with emphasis on obesity and type 2 diabetes management—A narrative review
Authors: Kim Hye Jin , Kwon Oran 
Published: May 2024

SummaryWhile a broad consensus exists that integrated nutrition and regular exercise are foundational for health maintenance and serve as a robust non‐pharmacological strategy against cardiometabolic diseases, the nuanced interplay between these elements remains incompletely understood. Through multifaceted interactions, these factors profoundly influence primary metabolic organs, notably the skeletal muscle and adipose tissue. Despite the critical nature of this interactivity, a holistic understanding of the combined effects of physical activity and dietary practices is still emerging. This narrative review aims to elucidate the intertwined roles of nutrition and exercise. It provides a comprehensive overview of their synergistic dynamics and emphasizes the importance of a dual‐focus approach in mitigating and managing cardiometabolic disorders, predominantly obesity and type 2 diabetes.

AbstractAlthough microalgae have only recently been recognized as part of the plant and soil microbiome, their application as biofertilizers has a tradition in sustainable crop production. Under consideration of their ability to produce the plant growth‐stimulating hormone cytokinin (CK), known to also induce pathogen resistance, we have assessed the biocontrol ability of CK‐producing microalgae. All pro‐ and eukaryotic CK‐producing microalgae tested were able to enhance the tolerance of tobacco against Pseudomonas syringae pv. tabaci (PsT) infection. Since Chlamydomonas reinhardtii (Cre) proved to be the most efficient, we functionally characterized its biocontrol ability. We employed the CRISPR‐Cas9 system to generate the first knockouts of CK biosynthetic genes in microalgae. Specifically, we targeted Cre Lonely Guy (LOG) and isopentenyltransferase (IPT) genes, the key genes of CK biosynthesis. While Cre wild‐type exhibits a strong protection, the CK‐deficient mutants have a reduced ability to induce plant defence. The degree of protection correlates with the CK levels, with the IPT mutants showing less protection than the LOG mutants. Gene expression analyses showed that Cre strongly stimulates tobacco resistance through defence gene priming. This study functionally verifies that Cre primes defence responses with CK, which contributes to the robustness of the effect. This work contributes to elucidate microalgae‐mediated plant defence priming and identifies the role of CKs. In addition, these results underscore the potential of CK‐producing microalgae as biologicals in agriculture by combining biofertilizer and biocontrol ability for sustainable and environment‐friendly crop management.
Consumer acceptance of microalgae as a novel food ‐ Where are we now? And how to get further
Authors: Olsen Malene Lihme , Olsen Karsten , Jensen Poul Erik 
Published: May 2024

AbstractMicroalgae provide a potential new food resource for sustainable human nutrition. Many microalgae species can produce a high content of total protein with a balanced composition of essential amino acids, healthy oils rich in polyunsaturated fatty acids, carotenoids, fibers, and vitamins. These components can be made available via unprocessed microalgae or refined as individual ingredients. In either case, if added to foods, microalgae may affect taste, smell, texture, and appearance. This review focuses on how consumer acceptance of new foods — such as microalgae — can be accessed in the world of sensory science by bringing together examples from recent consumer surveys. The main aim is to obtain an overview of the attitude towards microalgae as a food ingredient in Europe. The overarching finding suggests that European consumers generally find microalgae acceptable as ingredients in food products. However, there is a prevailing preference for keeping inclusion levels low, primarily attributed to the vivid green color that algae impart to food items upon addition. Additionally, consumers tend to favor the taste of freshwater algae over marine species, often finding the latter's pronounced fishy flavor less appealing.

AbstractThis study evaluates factors influencing pregnancy rates per artificial insemination (P/AI) and pregnancy loss in Lohi ewes undergoing laparoscopic AI with frozen–thawed semen under sub‐tropical conditions. Data from three experiments comprising ewes (n = 358) of mixed parity (nulliparous; NP and parous; P), various body condition score (BCS) and assigned to long‐term (LTP, 11 days) and short‐term (STP, 5 days) oestrus synchronization regimen across high breeding season (HBS) and low breeding season (LBS) were analysed. Laparoscopic insemination was conducted 54 h post‐sponge removal. Pregnancy diagnosis and loss were evaluated on days 35 and 90 post‐insemination via ultrasonography. Results showed parity significantly influenced P/AI, with nulliparous ewes achieving higher pregnancy ratios than parous ewes (p = .001). BCS significantly influenced P/AI (p < .05), with a quadratic relationship observed between BCS and season (BCS*BCS*Season; p = .07). Progestin treatment did not significantly influence the ratio of pregnant ewes (p = .07). Pregnancy losses were significantly higher during LBS than HBS (p < .05), irrespective of progestin treatment. In conclusion, parity and BCS significantly influenced P/AI, with BCS demonstrating a quadratic association with season. Ewes bred during LBS experienced higher pregnancy losses than HBS, irrespective of progestin treatment.

Published: May 2024

AbstractCrossbred cattle are commonly used for milk production in the tropics, combining the potential benefits of pure breeds with the heterosis effects of the offspring. However, no comprehensive assessment of lifetime productivity for crossbred versus purebred cattle in low‐altitude tropical environments has been carried out. The present study compares the lifetime productivity of purebred Holstein (HO, n = 17,269), Gyr (GY4, n = 435), and Brahman (BR4, n = 622) with crossbreds Gyr × Holstein (GY × HO, n = 5521) and Brahman×Holstein (BR × HO, n = 5429) cows from dairy farms located in low and medium altitude tropical regions in Costa Rica. The production traits of interest were age at first calving (AFC), days open (DO), milk production per lactation (TMP), lactation length (LLEN), age at culling (ACUL), and number of lactations (NLAC). Estimates of heterosis were also calculated. The AFC for GY × HO crosses (33–34 months) was not significantly different (p > .05) from HO (33.8 months). For BR × HO crosses, a significant (p < .05) decrease in AFC (BR3HO1 35.6 months, BR2HO2 34.5 months, and BR1H03 33.3 months) was observed as the fraction of HO breed increased. Estimates of heterosis for AFC were favourable for both crosses, of a magnitude close to 3%. The DO for F1 crosses (GY2HO2 94 days; BR2HO2 96 days) was significantly (p < .05) lower than HO (123 days). Estimates of heterosis for DO were also favourable and above 15% for both crosses. The TMP and LLEN were higher for HO (TMP = 5003 kg; LLEN = 324 days) compared with GY × HO (TMP = 4428 to 4773 kg; LLEN = 298 to 312 days) and BR × HO (TMP = 3950 to 4761 kg; LLEN = 273 to 313 days) crosses. Heterosis for TMP was favourable but low for both crosses, with a magnitude below 3.0%. The NLAC for HO (4.6 lactations) was significantly (p < .05) lower than F1 (GY2HO2, 5.8 lactations; BR2HO2, 5.4 lactations). Heterosis for NLAC was above 6.0% for both crosses. Overall, estimates of lifetime income over feed costs per cow on average were USD 2637 (30.3%) and USD 734 (8.4%) higher in F1 GY × HO and BR × HO, respectively, compared to HO. In conclusion, crossbred animals, specifically those with Gyr and Brahman genetics, extend the productive lifespan, increasing economic returns.

Published: May 2024

AbstractAimsThis study aimed to examine whether surgical treatment for a facial disfigurement influenced an individual's quality of life.Methods and ResultsOne‐on‐one interviews were conducted with the aim of synthesizing participant's medical experiences into common themes. Additionally, participants completed the World Health Organization's Quality of Life Brief Version (WHOQOL‐BREF) questionnaire. The WHOQL‐BREF is a standardized testing instrument with four domains of 26 questions, meant to analyze participants’ overall quality of health, physical health, psychological status, social relationships, and environmental health. Our study revealed that women with visible facial differences experienced a quality of life below the average of the general population. However, in those who reported above‐average quality of life, a key theme emerged: active participation in the choice to undergo surgical treatment. Participants who felt this sense of agency in the decision‐making process also reported a more positive healthcare experience. They felt more respected by others, indicating a strong connection between personal agency, surgical choices, and overall well‐being.ConclusionsThese findings reveal that personal agency plays an important role in the decision‐making process for patients undergoing surgical treatment for facial differences, as it improves quality of life and has a positive impact on overall healthcare experience and well‐being.
Freshwater plume‐like condition near the north‐eastern coastal Arabian Sea during early Miocene: Evidence from the stable isotope record in the growth bands of gastropods (Turritella sp.)
Authors: Banerjee Yogaraj , Ghosh Prosenjit 
Published: May 2024

AbstractThe Early Miocene witnessed major tectonic, palaeoceanographic and climatological reorganizations over the Asian realm. The Himalayan and Tibetan plateau upliftment influenced monsoon intensity during this age. Contemporary high‐resolution tropical hydroclimate records are limited. Here, we present an early Miocene sub‐annual stable isotope record from the growth bands of well‐preserved Turritella sp. from the Kachchh basin, Western India. It showed δ13C and δ18O variabilities from −4.83‰ to −1.80‰ and − 7.06‰ to −2.66‰ (in VPDB) respectively. Conventional oxygen isotope thermometry showed an apparent temperature seasonality from 9.3° to 28.1°C. A comparison of the present early Miocene δ18O record with the modern δ18O records in the carbonates from coastal‐estuarine environments of the Indian Ocean confirmed a high freshwater influx into the NE Arabian Sea during the early Miocene, similar to the modern‐day freshwater plume events observed in the coastal region.
Creating Low‐Carbon Economies: Probing Transition Dynamics through the Lens of Field Theory
Authors: Dörry Sabine , Schulz Christian 
Published: May 2024

AbstractWe employ field theory as an approach to analysing sustainable regional development by reconciling funding needs and funding procurement. Initial expectations that private capital would bridge the financial gap to decarbonize our economies and societies have not materialized. Instead, state‐led coalitions increasingly introduce spatialized decarbonization strategies in which public development banks are pivotal, yet underappreciated, actors. Field theory provides a fresh perspective for mapping the particular context in which regional industrial policies intersect with broader national and supra‐national investment programmes and funding needs for these long‐term initiatives. Transitions are typically directed but open‐ended social processes, necessitating agency to both alter context and institutions and stabilize the emerging new structures. Field theory can surpass limitations in approaches like transition studies and integrate change mechanisms across scales.
Flood susceptibility modeling by integrating tree‐based regression with metaheuristic algorithm, BWO
Authors: Satapathy Deba Prakash , Mishra Bibhu Prasad 
Published: May 2024

AbstractFloods are becoming more widely acknowledged as a common occurrence of nature's dangers on a global scale. Although forecasting models primarily focus on timely warnings, models aimed at evaluating dangerous zones can play a vital role in shaping policies for adaptation, mitigation, and reducing the risk of disasters. Using machine learning techniques including hybrid black widow optimization (BWO) with XGBoost, LGBoost, and AdaBoost. We generate a flood susceptibility map for considered region of lower mahanadi basin (LMB). This study examines the effectiveness of these machine learning models in assessing and mapping flood susceptibility, while also providing suggestions for future research in this area. Flood susceptibility model was developed using 13 variables: Altitude, Aspect, Curvature, Distance from river, Drainage Density, Stream Power Index (SPI), Sediment Transport Index (STI), Rainfall intensity, Land Use Land Cover (LULC), Topographic Wetness Index (TWI), Terrain Roughness Index (TRI), Normalized Difference Vegetation Index (NDVI), and slope. Additionally, flood inventory data were incorporated into the model. Dataset was divided into a 70% portion for training model and a 30% portion for validating model. To assess the performance of the model, several evaluation metrics were employed, including receiver operating characteristic (ROC) curve and other performance indices. Evaluation of flood susceptibility mapping, using ROC curve method in combination with flood density yielded strong and reliable results for various models. BWO‐XGBoost achieved a score of 0.889, BWO‐LGBoost achieved a score of 0.937, and BWO‐ADABoost achieved a score of 0.904. These scores indicate effectiveness of these models in accurately predicting flood susceptibility in the study area. A comparison was made with commonly used methods in flood susceptibility assessment to evaluate the efficiency of proposed models. It was found that having a first‐class and enlightening database is crucial for accurately classifying flood types in flood susceptibility mapping. This aspect greatly contributes to improving the overall performance of the model. Among the evaluated methods, the hybrid model BWO‐LGBoost demonstrated better performance compared with others, indicating its effectiveness in accurately predicting flood susceptibility.

ABSTRACT

Phage therapy has not been established in the clinical routine, in part due to uncertainties concerning efficacy and immunogenicity. Here, three rabbits were immunized against staphylococcal phage K to assess viral potency in the presence of immunized serum. Three rabbits received weekly intramuscular injections of ~10
10±1
pfu/mL phage K. Phage K-specific IgG formation was measured by an enzyme-linked immunosorbent assay (ELISA); phage inactivation was assessed by calculating K-rates. Using transmission electron microscopy (TEM) and immunogold labeling, antibody binding to phage K was visualized. This was numerically assessed by objective imaging analysis comparing the relative distances of each gold particle to the nearest phage head and tail structure. Immunization led to a strong IgG response, plateauing 7 days after the last phage injection. There was no significant correlation between K-rate and antibody titer over time. TEM showed IgG binding to the head structure of phage K. Image analysis showed a significant reduction in relative distances between antibodies and phage head structures when comparing samples from day 0 and day 28 (
P
< 0.0001). These results suggest that while individual serum analysis for antibodies against therapeutic phage bears consideration prior to and with prolonged therapy, during phage application, the formation of specific antibodies against phage may only partially explain decreased phage potency in the presence of immunized serum. Instead, other factors may contribute to an individual’s “humoral receptiveness” to phage therapy. Future investigations should be directed toward the identification of the humoral factors that have the most significant predictive value on phage potency
