The photochemical efficiency of photosystem II (PSII) was monitored in two-year-old seedlings from six Chilean woody sclerophyllous species differing in foliage habits (evergreen, deciduous, semi-deciduous) and leaf orientation. A common garden experiment was established in July 2020 in a Mediterranean-type climate site under two watering regimes (2 L⁻¹ seedling⁻¹ week⁻¹ for 5 months versus no irrigation). Chlorophyll a fluorescence rise kinetics (OJIP) and JIP test analysis were monitored from December 2021 to January 2022. The semi-deciduous Colliguaja odorifera (leaf angle of 65°) exhibited the highest performance in processes such as absorption and trapping photons, heat dissipation, electron transport, and level of photosynthetic performance (i.e., parameters PI_ABS F_V/F_M, F_V/F₀, and ΔV_IP). In contrast, the evergreen Peumus boldus (leaf rolling) exhibited the opposite behavior for the same parameters. On the other hand, the deciduous Vachelia caven (small compound leaves and leaf angle of 15°) showed the lowest values for minimal and maximal fluorescence (F₀ and F_M) and the highest area above the OJIP transient (S_m) during the study period. Irrigation decreased S_m and the relative contribution of electron transport (parameter ΔV_IP) by 22% and 17%, respectively, but no clear effects of the irrigation treatments were observed among species and dates of measurement. Overall, V. caven and C. odorifera exhibited the highest photosynthetic performance, whereas P. boldus seemed to be more prone to photoinhibition. We conclude that different foliar adaptations among species influence light protection mechanisms more than irrigation treatments. Full article

Background/Objectives: The improvement of sleep quality is unquestionably a critical issue in public health. While numerous factors influence sleep quality, the relative importance of dietary habits remains insufficiently understood. The objective of this study is to evaluate the contribution of dietary habits by quantitatively comparing the effects of various determinants of sleep quality. Methods: Using sleep diary data from healthy males and females residing in a specific region of Japan, we estimated a dynamic multivariate panel model (DMPM) to obtain posterior predictive distributions on a scale that allows for comparisons across factor categories. Three outcome variables were adopted to measure sleep quality: presence or absence of daytime drowsiness, ease of falling asleep, and ease of waking up. The determinants of sleep quality examined in the analysis were categorized into six groups: stress factors, bedtime conditions, weather conditions, physical characteristics, exercise habits, and dietary habits. Results: The analysis revealed that although there were some seasonal and gender differences, dietary habits showed effect sizes that were no smaller than those of other determinants across all outcome variables. Conclusions: These results suggest that improving dietary habits, along with enhancing exercise habits and bedtime conditions, is a valid and equally important strategy for promoting better sleep.

Specialized herbivores like giant pandas (Ailuropoda melanoleuca), red pandas (Ailurus fulgens), and bamboo rats, which primarily consume bamboo, are at risk of nutrient deficiencies, particularly vitamin B12 (VB12), potentially leading to cardiovascular diseases. This study explored the effects of VB12 supplementation on cardiovascular health in silver star bamboo rats (Rhizomys pruinosus). We first conducted a comprehensive genome annotation of R. pruinosus, laying the foundation for in-depth evolutionary studies. Comparative transcriptomic analysis revealed that genes related to cardiovascular disease (e.g., Sgcb, Adcy2, Itga1, Itgb8, Ifng, and Gpc1) were upregulated in the livers of R. pruinosus compared to carnivorous and omnivorous rodents, indicating a higher cardiovascular disease risk. After 60 days of VB12 supplementation, liver transcriptome analysis revealed significant improvements in cardiovascular health markers, including reduced cholesterol synthesis and enhanced fatty acid metabolism. Serum biochemical assays indicated that VB12 supplementation led to reduced homocysteine levels, decreased low-density lipoprotein (LDL)-to-high-density lipoprotein (HDL) ratios, and increased the apolipoprotein A-to-apolipoprotein B ratio. These findings suggest that VB12 may mitigate cardiovascular disease risk and could be considered in the dietary management of specialized bamboo-eating species. Our study provides valuable insights into disease prevention strategies for these species with similar dietary habits. Full article

In the current context where China is continuously emphasizing the construction and supply of indemnificatory housing, and actively promoting the construction of “Better Housing” for such housing, the development experiences of Japan and South Korea in the field of public housing reveal that the construction and supply of public housing cannot be separated from the interaction and coordinated development of the policy system, spatial composition, and cultural factors. Based on this, this study takes the public rental housing in China, Japan, and South Korea as the research objects, through comparative analysis of their policy systems, cultural backgrounds, and spatial composition characteristics of unit plans, to explore the implications for the development of China’s indemnificatory housing, and provides theoretical basis and practical references for optimizing the supply system and space design of China’s indemnificatory housing. The study selects typical cases of public rental housing from the three countries, and conducts comparisons from dimensions such as unit plane shape, L.D.K. layout, bedroom configuration, transitional space, balcony design, and bathroom composition. Findings indicate that Japan’s UR rental housing focuses on refined and diversified design, South Korea’s public housing emphasizes spatial flexibility, while China’s indemnificatory housing, while pursuing standardized construction, faces challenges of area limitations and insufficient functional adaptability. Based on the experiences of the three countries, this study proposes a tripartite guidance suggestion of “Policy–Space–Culture” to advance the realization of “Better Housing” objectives and ensure that China’s indemnificatory housing meets both international advanced experience and local social and cultural specific needs: (1) policy systems—strengthening legalization and long-term sustainability in governance; (2) spatial composition—incorporating flexible layouts and human-centric detailing; (3) cultural adaptability—balancing traditional living habits with contemporary needs.

Background/Objectives: Childhood obesity represents a pressing global health challenge, demanding coordinated, long-term strategies. Schools and families are pivotal environments for shaping children’s lifestyle behaviors. The LIVELY project aimed to assess overweight/obesity prevalence and associated factors in primary school children, and to implement a multidimensional educational intervention promoting healthy, sustainable lifestyles. Methods: This single-arm study was conducted from October 2023 to October 2024 in a primary school in Milan. The intervention included age and culturally tailored lessons, games, and activities. Anthropometric measures, dietary adherence, and lifestyle habits were assessed before and after the intervention. Satisfaction surveys were administered to children, families, and teachers. Results: The project involved 227 children across 14 classes (mean age 8.9, SD 1.2 years). The prevalence of overweight/obesity was 23.4%. Adherence to the Mediterranean Diet was moderate, limited by low intake of vegetables, nuts, and dairy. Physical activity was low, screen time excessive, and sleep insufficient. No statistically significant improvements in anthropometrics or diet adherence were observed post-intervention, but positive trends emerged for physical activity, sleep, and hydration. Over half of the children passed the nutritional knowledge test. Despite these challenges, high satisfaction levels have been shared by children, parents, and teachers. Conclusions: The limited duration of the intervention and challenges engaging families in a low socio-economic context may have constrained the impact of the program, and caution is advised in generalizing the findings. The LIVELY project highlights the complexity of tackling childhood obesity in multicultural settings and emphasizes the need for longer, continuous, and culturally tailored programs that actively involve families to promote sustainable healthy behaviors.

The individual’s willingness to pay (WTP) for environmental reduction programs is one way of gauging society’s environmental consciousness. We explore the determinants of an individual’s WTP for a product produced from carbon capture and utilization (CCU) technology in Qatar. A representative questionnaire sample was administered to 1012 respondents in Qatar on habits, perceptions, economic and religious attitudes related to environmental consciousness, and WTP. The findings reveal that environmental concern is significantly enhanced by environmental consciousness, awareness, and education, while environmental awareness also positively influences perceived social norms regarding others’ environmental awareness. Further, environmental consciousness, religiosity, and education are significantly positively associated with the WTP for an eco-friendly product. Also, those who earn high incomes have a greater WTP for eco-friendly products with premium prices of 10–75% higher. Respondents motivated by religious obligation have a significantly greater WTP for eco-friendly products with a 10–30% price premium. These findings imply the need for context-specific strategies that leverage cultural values, address income disparities, and effectively communicate the benefits of green choices to drive the adoption of green products.

Obesity has become a major public health crisis and serves as an underlying condition for other chronic metabolic diseases. The dysregulation of the inhibitory and regulatory mechanisms of the mesolimbic dopamine system, particularly dopamine D2 receptors (D2Rs), plays a critical role in driving excessive food consumption and compulsive eating habits. Based on the current literature, chronic consumption of high-fat foods elicits hedonic sensations and has the potential to downregulate and desensitize D2Rs, impairing their signaling and inhibitory action. This impairment thereby alters the downstream signaling of the D2Rs, involving the inhibition of adenylyl cyclase and the associated cascade. Although individual components of this proposed pathway have been studied, a comprehensive synthesis has not been established. This review aims to explore the relationship between D2R downregulation and desensitization and their effects on the downstream signaling cascade. We hypothesize that alterations in this pathway may lead to the dysregulation of the expression of orexigenic and anorexigenic neuropeptides, contributing to binge-eating behaviors. Full article

Background/Objectives: Proper nutrition is crucial for the growth, development, and performance of young football players. Despite higher nutritional needs, physically active adolescents often have a suboptimal diet. This study assessed the diet quality of youth football players aged 11–16 from Poznań, Poland, focusing on the frequency of consuming health-promoting and non-healthy food groups. Methods: Participants were Football Championship School students. A total of 78 boys were analyzed and divided into early (11–13 years) and middle adolescence (14–16 years) groups. Dietary behaviours, nutritional knowledge, physical activity, screen time, and family affluence were assessed using a validated questionnaire (SF-FFQ4PolishChildren). The pro-Healthy Diet Index (pHDI) and non-Healthy Diet Index (nHDI) were calculated based on the frequency of food consumption. Results: The key predictors of the pro-Healthy Diet Index (pHDI) were the Cole index (β = −0.39; p < 0.001), subjective self-assessment of dietary habits (β = 0.23; p = 0.023), and the level of nutritional knowledge (β = 0.22; p = 0.030), explaining 25% of the variance in pHDI. In early adolescence, the Cole index was the main predictor (β = −0.51, p < 0.001, R² = 32%), whereas in middle adolescence, self-assessment of dietary habits (β = 0.49, p = 0.002) and nutritional knowledge (β = 0.34, p = 0.03, R² = 30) were the strongest predictors. Despite high levels of physical activity and positive self-assessment, only 1.28% of participants met all key criteria for a healthy diet. Screen time was negatively correlated with physical activity and positively associated with energy drink consumption. Conclusions: The results highlight a discrepancy between declared knowledge and actual behaviours, emphasizing the need for targeted, multi-level interventions involving families and coaches to improve dietary practices in young athletes.

Background/Objectives: To prevent nutritional depletion and impaired weight status in infants, targeted public health policies and prevention programs based on scientific evidence are needed. This study provides an overview of the dietary patterns and feeding behavior of infants in Croatia as part of the National Food Consumption Survey on Infants and Children. Methods: This cross-sectional study was conducted following the EU Menu methodology and included 322 healthy infants (54% boys; aged 3 months up to 12 months) from Croatia. Two-day dietary records were collected and analyzed using NutriCro 2.0 software. Results: The daily energy intake of infants was on average 886 ± 219 kcal, mainly from carbohydrates (47.0%), followed by fat (41.6%) and protein (9.9%). The main sources of energy and macronutrients were milk and dairy products, grains, grain products, potatoes and tubers and the fruit food group. One third of infants were breastfed, and more than 70% of infants were introduced to complementary foods. Parents started complementary feeding at the age of 5.37 ± 0.82 months, mostly with vegetables. Breastfeeding was associated with higher energy intake, especially in infants younger than 6 months, while formula feeding was associated with lower energy intake. The multivariate regression models showed age-related interactions that attenuated the patterns for energy and macronutrient intake. Conclusions: The study emphasizes that milk and dairy products are the main source of energy and macronutrients. The study highlights the important role of breastfeeding in promoting higher energy intake in early infancy and the decreasing effect of infant formula consumption with age. These results can be used as a basis for health policies, programs and strategies that address infant feeding habits in Croatia. Full article

One of the major social issues worldwide is tobacco dependency and cigarette smoking (CS) abuse. Given the significant impact of cigarette smoking on human health and diseases, extensive tobacco use and cigarette smoking abuse are certainly a form of drug addiction and should be considered a serious threat to human health. Notably, healthcare spending attributable to cigarette smoking is very high. In this regard, a significant number of biomolecules of natural origin have been described as capable of mitigating the adverse effects of cigarette smoking. In this review, (a) we discuss the impact that the habit of smoking tobacco has on human health and (b) we describe products of natural origin capable of mitigating the effects of cigarette smoke. The conclusion of this review article is that the available information strongly indicates a possible use of the anti-inflammatory aged garlic extract (AGE) and its bioactive components for mitigating the detrimental effects of cigarette smoke on human tissues. The key reasons for proposing this application are that AGE and its key components S-allyl-cysteine and S1-propenyl-cysteine are potent anti-inflammatory agents, bind to Toll-like Receptor-4, inhibit Nuclear Factor-κB, inhibit the expression of pro-inflammatory genes, revert apoptosis induced by cigarette smoke in several cellular model systems and are strong inhibitors of Reactive Oxygen Species (ROS) formation.

This study explores how Turkish Generation Z adapts their fashion consumption behaviours in response to economic crises, particularly focusing on involuntary anti-consumerism. Through a qualitative methodology using semi-structured interviews and purposive sampling, the research captures the coping strategies and emotional experiences of young consumers in Türkiye. A thematic analysis of fifteen interviews reveals an original “8Rs” framework—Reject, Restrict/Reduce, Reuse/Reclaim, Re-find, Reconsider, Re-framing Discounts, Re-direction of Resources, and Emotional Responses—that illustrates both behavioural and psychological adjustments under financial strain. Notably, the study introduces two novel concepts: “recession rush,” a calculated urgency to purchase before price hikes, and “re-direction of resources,” the reallocation of budget from other categories toward fashion purchases. By focusing on a geographically underrepresented context and a pivotal consumer segment, this research contributes new insights to the literature on anti-consumption, economic adaptation, and youth identity expression in crisis economies.

Background: Obesity is multifactorial, shaped by biological, behavioral, and psychosocial factors. Traditional sociodemographic and lifestyle influences are well studied, but psychological well-being, particularly life purpose, remains less explored. This study investigates associations between demographics, health behaviors, and life purpose and obesity prevalence, assessed through four validated adiposity indices in Spanish workers. Methods: This cross-sectional study included 93,077 workers (mean age: 43.8 ± 9.6 years; 54.1% men). Obesity was defined according to four measures: body mass index (BMI), waist-to-height ratio (WtHR), Clínica Universidad de Navarra Body Adiposity Estimator (CUN-BAE), and Metabolic Score for Visceral Fat (METS-VF). Sociodemographic, lifestyle (Mediterranean diet, physical activity, smoking), and psychological (Purpose in Life Test, PIL-10) variables were assessed. Logistic regression was used to evaluate associations with obesity risk. Results: Low life purpose was significantly associated with increased odds of obesity across all indices, particularly for CUN-BAE (OR = 4.58; 95% CI: 3.99–6.28) and BMI (OR = 5.45; 95% CI: 4.71–6.30). Traditional risk factors such as physical inactivity, poor adherence to the Mediterranean diet, older age, a lower social class, and smoking also demonstrated strong associations with higher adiposity levels. METS-VF showed the greatest sensitivity to male sex and unhealthy behaviors. Conclusions: This study identifies life purpose as an independent psychosocial determinant of obesity. Using multiple adiposity measures strengthens the findings, emphasizing psychological well-being in prevention. Longitudinal research is needed to confirm causality and develop interventions enhancing life purpose to improve cardiometabolic health. Given the cross-sectional design, causal inferences cannot be drawn and the directionality of associations remains uncertain. Full article

This paper proposes a novel bio-inspired metaheuristic algorithm called the Red-crowned Crane Optimization (RCO) algorithm. This algorithm is developed by mathematically modeling four habits of red-crowned cranes: dispersing for foraging, gathering for roosting, dancing, and escaping from danger. The foraging strategy is used to search unknown areas to ensure the exploration ability, and the roosting behavior prompts cranes to approach better positions, thereby enhancing the exploitation performance. The crane dancing strategy further balances the local and global search capabilities of the algorithm. Additionally, the introduction of the escaping mechanism effectively reduces the possibility of the algorithm falling into local optima. The RCO algorithm is compared with eight popular optimization algorithms on a large number of benchmark functions. The results show that the RCO algorithm can find better solutions for 74% of the CEC-2005 test functions and 50% of the CEC-2022 test functions. This algorithm has a fast convergence speed and high search accuracy on most functions, and it can handle high-dimensional problems. The Wilcoxon signed-rank test results demonstrate the significant superiority of the RCO algorithm over other algorithms. In addition, applications to eight practical engineering problems further demonstrate its ability to find near-optimal solutions. Full article
