Stamens enclosed by petals in Berchemia (Rhamnaceae): a unique mechanism for pollen presentation
Authors: Ma Fang , Zhao Qian , Tian Xing , Fu Yao-lei , Liu Wen-zhe 
Published: January 2025

IntroductionPollen is usually presented by the anthers after maturity. However, in some plants, pollen is presented to pollinators on other floral structures (other than the anthers), or via particular expulsion mechanisms, resulting in secondary pollen presentation. The unusual petal morphology in Berchemia mediates pollen presentation, characterised by a combination of secondary pollen presentation and primary pollen presentation. However, the function, the role in reproduction, and the evolutionary significance of the unusual petals remain unclear.MethodsIn this study, we took Berchemia flavescens and Berchemia polyphylla var. leioclada as examples, and used field observations, semi-thin sections technology, scanning electron microscopy, and pollination ecology detection methods to explore the unique pollen presentation strategies, petal functions, and reproductive strategies in Berchemia.ResultsThis is a unique pollen presentation process mediated by petals. In the advanced bud stage, petals curl inward, enclosing the stamens. Following anther dehiscence, pollen is released into the petal tube, where the filament and cone-shaped anthers act as pistons, extruding pollen or pollen clumps through gaps at the petal tube apex (secondary pollen presentation). Subsequently, as the anthers emerge from the petal tube, residual pollen is directly presented to pollinators (primary pollen presentation).DiscussionIn Berchemia, the petals enclosing the stamens, effectively shield the pollen from extreme environmental conditions. The petal-stamen complex slow movement (first centrifugal, later centripetal) and pollen presentation in Berchemia suggest a unique reproductive strategy. This mechanism promotes outcrossing, minimizing interference between the pistil and stamens, and offers reproductive assurance by delayed self-pollination.

Published: January 2025

BackgroundAdolescence and technological devices have a close relationship during this stage in which anxiety about using a cell phone increases when it is not available. The Nomophobia Scale (NMP-Q) is a measure that evaluates anxiety behaviors when being without a mobile phone.ObjectiveTo evaluate the psychometric properties of the Nomophobia Questionnaire (NMP-Q) in Peruvian adolescents.MethodsAn instrumental study was conducted and 900 adolescents of both sexes, between 12 and 17 years old, living in northern, rural, and eastern regions of Peru were evaluated. A confirmatory factor analysis was carried out to determine the structure and the structural invariance of the measures according to age was evaluated and the reliability was estimated by means of the Omega reliability coefficient.ResultsThe four--factor structure composed of 20 items was confirmed with optimal goodness-of-fit indices (CFI = 0.992; TLI = 0.991; SRMR = 0.053; RMSEA = 0.039). The MIMIC models reported invariance for age groups (ΔCFI &lt;0.01, ΔRMSEA &lt;0.015). The omega reliability coefficients ranged between 0.84 and 0.90.”ConclusionThe Peruvian version of the NMP-Q (20 items) has shown adequate psychometric properties to assess nomophobia in the adolescent population.

Published: January 2025

IntroductionNature-based art therapy is a therapeutic approach that uses natural elements and settings to promote well-being and health through creative expression, facilitated by a professional art therapist. Interest in nature-based mental health approaches surged, particularly following the COVID-19 lockdowns, as research highlights nature’s role in health restoration and sustainability. Despite growth in the field, a comprehensive overview of nature-based art therapy remains absent. This scoping review aimed to map the research landscape and identify the thematic scope within this emerging field.MethodsA systematic search following the PRISMA-ScR guidelines across the ProQuest, SAGE, Scopus, Taylor &amp; Francis, and ScienceDirect databases identified 11 publications that address art therapy involving nature and are published in English.ResultsThe review identified four key themes: areas of focus, nature engagement, core elements, and challenges in nature-based art therapy. The areas of focus encompassed overall mental health and well-being, emotion regulation and stress management, cognitive development, social bond and support, self-discovery and personal growth, trauma and grief management, creative self-expression, and environmental sustainability. The core elements, such as artwork, materials, and therapy settings, were identified. Although nature-based therapy, involving both direct and indirect nature engagement, described promising benefits, specific challenges, including complexities in client assistance, constraints in nature access, psychosocial and cultural barriers, and risk management, were also highlighted.DiscussionThis scoping review provides a comprehensive framework for understanding nature-based art therapy and underscores the need for further theoretical and practical evidence-based development in this field.

BackgroundAs an inherent cognitive process in the pursuit of progress among college students, achievement motivation has become an indispensable facet of daily life. This study aims to investigate the association between physical exercise and achievement motivation, while also examining the mediating roles played by self-efficacy and life satisfaction.MethodsThis study employed a cross-sectional survey methodology, with a sample of 900 Chinese university students as the research participants. A total of 844 valid questionnaires were collected and analyzed. The participants completed various scales, including measures of sports activity level, self-efficacy, life satisfaction, and achievement motivation. Subsequently, comprehensive descriptive statistical analyses were conducted on the gathered data.Results and conclusionA significant positive correlation is present between physical exercise and achievement motivation (r = 0.464, p &lt; 0.01), self-efficacy (r = 0.288, p &lt; 0.01), and life satisfaction (r = 0.333, p &lt; 0.01) among college students. Moreover, achievement motivation demonstrates a positive association with self-efficacy (r = 0.506, p &lt; 0.01) and life satisfaction (r = 0.399, p &lt; 0.01). Furthermore, the relationship between physical exercise and achievement motivation can be influenced by both self-efficacy and life satisfaction as mediators in our constructed mediation model where the total effect is 0.512 with direct effect of 0.348 and indirect effect of 0.163. The results of the constructed mediating effect model demonstrate that self-efficacy and life satisfaction serve as significant mediators and moderators, effectively enhancing the achievement motivation levels of college students. This study provides novel insights for enhancing intervention strategies to improve levels of achievement motivation not only among Chinese but also global college students.

IntroductionThis study aimed to investigate the role of TAAR2-9 in sleep/wake regulation, given TAAR1's known involvement in modulating neurotransmitter release and sleep patterns.MethodsMale TAAR2-9 knockout (KO) and wild-type (WT) mice were compared using baseline sleep/wake patterns, responses to sleep deprivation, effects of TAAR1 agonists, and dopaminergic markers. EEG recordings and tyrosine hydroxylase immunohistochemistry were used for analysis.ResultsKO mice exhibited lower delta and theta power and higher gamma power, with fragmented sleep characterized by 16% more NREM sleep during the dark phase and 23% more REM sleep during the light phase compared to WT mice. High doses of the TAAR1 agonist RO5256390 increased wakefulness and reduced NREM sleep, while both RO5256390 and the partial agonist RO5263397 suppressed REM sleep in KO mice. Elevated tyrosine hydroxylase levels in the ventral tegmental area suggested dopaminergic involvement in these altered sleep patterns.DiscussionTAAR2-9 modulates sleep/wake states and interacts with TAAR1. These findings highlight the therapeutic potential of targeting TAARs 2-9 in sleep-related neuropsychiatric disorders. Further research is needed to elucidate their roles.

BackgroundThis study aimed to investigate the relationship between urinary fluoride concentration and myocardial disease.MethodsThis is a cross-sectional study that was conducted in three villages in Wenshui County, Shanxi Province. A total of 737 villagers were included in this analysis. Urinary fluoride was detected using a fluoride-ion selective electrode. Myocardial enzymes were detected using an automatic biochemical analyzer. Myocardial ischemia and arrhythmia were diagnosed using 12-lead electrocardiogram.ResultsThe median level of urinary fluoride concentration was 1.32 mg/L. Urinary fluoride was associated with serum creatine kinase (CK) elevation (odds ratio [OR] = 1.39 [95% confidence interval (CI)]: 1.09–1.78) and CK isoenzyme (CK-MB) elevation (OR = 1.49 [95% CI: 1.12–1.97]). Stratified analysis revealed that urinary fluoride concentration was associated with CK elevation in villagers under the age of 60 years (OR = 1.80 [95% CI: 1.26–2.59]). This study found that there was a positive association between urinary fluoride concentration and the risk of CK-MB elevation in participants under the age of 60 years(OR = 2.18 [95% CI: 1.39–3.42]), those who were of female gender (OR = 1.53 [95% CI: 1.07–2.19]), those who were overweight/obese (OR = 1.96 [95% CI: 1.28–2.99]), those who had central obesity (OR = 1.59 [95% CI: 1.12–2.25]), consumed alcohol (OR = 1.49 [95% CI: 1.09–2.05]), and smoked (OR = 1.50 [95% CI: 1.10–2.04]).ConclusionOur study suggests that fluoride exposure is associated with the risk of serum CK and CK-MB elevation; however, it is not associated with myocardial ischemia, arrhythmia, serum lactate dehydrogenase (LDH), serum alpha-hydroxybutyrate dehydrogenase (α-HBD), or serum aspartate aminotransferase (AST). Further investigations are needed to substantiate our findings and explore the potential underlying mechanisms.

Published: January 2025

ObjectiveIn order to improve knowledge of HIV transmission dynamics and guide preventive and control strategies, this work uses molecular cluster analysis to objectively detect clusters of HIV genetic sequence similarity.Methods89 HIV-positive couples provided blood samples, and plasma was separated for pol region gene sequence amplification. Furthermore, analyzed HIV-1 pol fragment sequences from Nanjing patients between 2015 and 2019. HYPHY and Cytoscape were used to generate and illustrate molecular networks.ResultsIn this investigation of 89 double-positive pairs, it was discovered that the pairwise gene distance approach properly detected 82.02% of positive couples at an ideal gene distance of 0.014 substitution/loci. With an accuracy of 86.25%, the optimal parameter for the phylogenetic tree and gene distance approach was 90 + 0.045 substitution/loci. A molecular network was built for the Nanjing samples (2015–2019) using the optimum threshold of the previous technique. This network had 487 sequences with one misconnected cluster. There were 565 sequences in the network created by the latter approach that were not incorrectly connected.ConclusionFor HIV research, molecular cluster analysis provides novel insights. It helps with preventive and control methods by objectively identifying clusters with comparable genetic sequences, which enhances our knowledge of HIV transmission. Further developments will increase its importance for HIV/AIDS research and worldwide prevention.

IntroductionSexual violence against adolescent girls and young women (AGYW) is a pervasive issue globally, with particularly high prevalence in sub-Saharan Africa. This study explores the drivers and prevention strategies for sexual violence among AGYW in Kicukiro, Rwanda.MethodsA descriptive exploratory design guided by the socioecological model and feminist standpoint theory was employed. In-depth interviews were conducted with 13 AGYW participating in a mentorship program and 5 male community members. Data was analyzed using thematic analysis to identify key drivers and potential prevention strategies.ResultsFour themes emerged: (1) empowering mentorship programs, (2) tiered drivers of sexual violence, (3) optimizing violence-mitigating resources, and (4) interference with judicial processes. Key drivers of sexual violence included substance use, transactional sexual relationships, inadequate family protection, entrenched gender stereotypes, and limited legal literacy.ConclusionFindings underscore the need for multifaceted interventions that address systemic and cultural barriers, strengthen legal frameworks, and expand community-based programs. Addressing sexual violence requires a holistic approach, integrating empowerment initiatives, robust community engagement, and legal reforms to create safer environments for AGYW. The mentorship program's success suggests scalability across other settings.
The effects of adolescents' sleep duration on life satisfaction: utilizing the autoregressive cross-lagged (ARCL) model
Authors: Jung Eun Jin 
Published: January 2025

IntroductionSleep duration in youth is a key factor that significantly influences mental health. However, there have been limited studies examining the direct impact of adolescents' sleep on life satisfaction. This study aims to analyze the effects of adolescents' sleep duration on their life satisfaction.MethodsFor this purpose, data from the Korean Children and Youth Panel Survey (KCYPS) conducted by the National Youth Policy Institute (NYPI) were utilized, specifically focusing on the 4th-grade panel data (N = 2,378; 52.4% male; 47.6% female). Analysis revealed a rapid decline in youth sleep duration upon entering junior high school. Consequently, the data were categorized into two periods for analysis: Year I (4th grade) to Year IV (7th grade), and Year IV (7th grade) to Year VII (10th grade).ResultsUsing the autoregressive cross-lagged (ARCL) model, it was found that sleep duration during Years IV-VII significantly influenced life satisfaction over time. An increase in sleep duration led to a subsequent increase in life satisfaction over time with statistical significance. Specifically, sleep duration during 7th grade exhibited a significant static influence on life satisfaction at 8th grade (β = 0.025, p &lt; 0.03), while sleep duration during 8th grade statically affected life satisfaction during 9th grade (β = 0.026, p &lt; 0.03). Moreover, sleep duration at 9th grade had a static influence on life satisfaction during 10th grade, with statistical significance (β = 0.027, p &lt; 0.03).DiscussionBased on the findings of this study, implications and suggestions for future research were discussed. It is essential to create an environment that promotes adequate sleep for adolescents, even after they enter junior high school.

IntroductionPreserving and revitalizing culture to ensure authenticity for tourism development is a critical concern, especially as modern societal changes have eroded numerous traditional cultural values. Most local tourism development efforts primarily focus on meeting tourists' demands, often overlooking the perspectives of local communities who practice these unique cultures. This study, grounded in constructivist grounded theory, emphasizes the importance of conducting research from the local perspective to maintain authenticity in cultural preservation and to balance the interests of local people, tourists, and stakeholders.MethodsThe qualitative research method employed included fieldwork and focus group discussions conducted in A Luoi district, Thua Thien Hue province, Vietnam. Fieldwork and participation observations allow to capture information about the research area as well as the experiences and behaviors of the local community. Furthermore, focus groups were conducted with 20 Ta Oi people, divided into two groups: the elderly (aged over 50) and the young people, to gather thorough and various information from their perspective on the meaning and the revitalization of local culture. The data were analyzed thematically.ResultsThe findings reveal that the Ta Oi people have revitalized four key cultural practices through tourism, including Dzeng weaving, traditional landscapes and architecture, traditional cuisine, and traditional art performances, rituals, and beliefs. In addition, cultural revitalization is also mentioned through people's perception of the authority's role and the adjustment of cultural activities toward tourism development. These practices have been adapted to fit the modern context, demonstrating that cultural revitalization is not about restoring traditions in a static form but rather reconstructing them to meet evolving societal and economic demands.DiscussionThe research illustrates the adaptability and creativity of local people in preserving and revitalizing traditional culture, along with their enthusiasm and willingness to take action. Cultural preservation is not a top-down process; instead, it is co-created by the Indigenous community itself, shaped by differing viewpoints between elder and younger generations. This ensures that while cultural traditions may evolve, they are still rooted in the values and identity of the Indigenous people, rendering the cultural revival process both sustainable and meaningful in the context of tourism. The research findings serve as a crucial foundation for guiding local government policies on cultural preservation and tourism development.
