Distinct interactions of ericoid mycorrhizae and plant growth-promoting bacteria: impacts on blueberry growth and heat resilience

ABSTRACT Blueberries confront substantial challenges from climate change, such as rising temperatures and extreme heat, necessitating urgent solutions to ensure productivity. We hypothesized that ericoid mycorrhizal fungi (ErM) and plant growth-promoting bacteria (PGPB) would establish symbiotic relationships and increase heat stress tolerance in blueberries. A growth chamber study was designed with low (25/20°C) and high temperature (35/30°C) conditions with micropropagated blueberry plantlets inoculated with ErM, PGPB, and both. Gas exchange and chlorophyll fluorescence properties of the leaves were monitored throughout the growth. At harvest, biochemical assays and biomass analysis were performed to evaluate potential oxidative stress induced by elevated temperatures. ErM application boosted root biomass under 25/20°C conditions but did not impact photosynthetic efficiency. In contrast, PGPB demonstrated a dual role: enhancing photosynthetic capacity and reducing stomatal conductance notably under 35/30°C conditions. Moreover, PGPB showcased conflicting effects, reducing oxidative damage under 25/20°C conditions while intensifying it during 47°C heat shock. A significant highlight lies in the opposing effects of ErM and PGPB on root growth and stomatal conductance, signifying their reciprocal influence on blueberry plant behavior, which may lead to increased water uptake or reduced water use. Understanding these complex interactions holds promise for refining sustainable strategies to overcome climate challenges.

Twenty-year tango: Exploring the reciprocal influence of macro-financial instability and climate risks

This study presents a novel investigation of the reciprocal relationship between financial instability and climate risks, focusing on the influence of climate policy uncertainty within the US financial system from a macroeconomic perspective. By adopting the bootstrap rolling-window causality method, the analysis captures structural changes over an extended period between January 2000 and March 2021. Importantly, this method provides a robust data-driven approach, avoiding ad hoc assumptions about temporal breakpoints. The results support the climate fragility hypothesis, highlighting the amplifying effect of financial instability on climate risks. The study reveals that periods of economic and political turbulence exacerbate these effects by generating substantial financial turbulence, which, in turn, influences climate policy. The results also indicate that climate policy uncertainty contributes to worsening financial instability during critical events such as sudden changes in interest rates and major financial crises. The implications of this research extend to policymakers and investors, encouraging them to integrate climate factors into decision-making processes and adopt sustainable practices to promote financial stability and mitigate climate-related risks.

Evolution of intraspecific floral variation in a generalist-specialist pollination system.

Intraspecific processes impact macroevolutionary patterns through individual variation, selection, and ecological specialisation. According to the niche variation hypothesis, the broader ecological niche of gen- eralist species results in an increased morphological variation among individuals, either because they are constituted of diversified specialised individuals each exploiting a fraction of the species' niche, or because they are constituted of true generalist individuals that experience relaxed selection. To test this hypoth- esis, we surveyed the individual floral morphology of species of Antillean Gesneriaceae, a group that has transitioned between specialisation for hummingbird pollination and generalisation multiple times throughout its evolutionary history. We characterised the profiles of corollas using geometric morpho- metrics and compared the intraspecific shape variance of specialists and generalists in a phylogenetic context. We used three approaches that differently accounted for the high dimensionality of morphologi- cal traits, the ancestral reconstruction of pollination syndromes over time, and the error associated with the estimation of the intraspecific variance. Our findings provide partial support for the niche variation hypothesis. If considering the whole shape in the analysis corroborated this idea, decomposing the shape into principal components indicated that not all aspects of the corolla exhibit the same pattern of vari- ation. Specifically, pollination generalists tend to display greater intraspecific variation than specialists in terms of tubularity, but not of curvature. Accounting for the error in the variance estimation also reduced the support for the hypothesis, suggesting that larger sample sizes may be required to reach stronger conclusions. This study emphasises the reciprocal influence between plants and their pollinators on floral morphology at different biodiversity scales, and suggests that ecological strategies of species can affect patterns of morphological variation at macroevolutionary scales.

Longitudinal processes among humility, social justice activism, transcendence, and well-being.

Existing research shows positive associations between humility and well-being, and between civic engagement and well-being. Rarely have humility, civic engagement, and well-being been examined together. We build off of previous cross-sectional findings and a prior longitudinal study that used three waves of data and found significant positive bivariate correlations between humility and the presence of life purpose across time points. Extending these previous findings, we used six waves of data obtained from graduate students at 18 seminaries across North America (N = 574; Mage = 31.54; 46.7% female; 65.3% White) to explore the dynamic associations among humility and life purpose, along with horizontal transcendence (an indicator of the attitudinal dimension of civic engagement) and social justice activism (an indicator for the behavioral dimension). We explored reciprocal short-run processes and dynamic long-run effects using a general cross-lagged panel model. We found robust evidence for a reciprocal influence between the presence of life purpose and horizontal transcendence, and long-run effects for initial levels of life purpose to influence later levels of horizontal transcendence. We also found long-run effects for the influence of initial levels of life purpose on later levels of humility, and initial levels of social justice activism on later levels of horizontal transcendence. Implications center on the use of the findings for planning future one-time life purpose and social justice interventions to affect changes in humility and horizontal transcendence.

The role of self-compassion in the association between childhood maltreatment and marital quality: An actor-partner interdependence model.

Childhood maltreatment (CM) is a significant risk factor for intimate relationship and marital quality. However, there has been limited research exploring the underlying mechanisms of this link, with most studies focusing on individuals, while not considering the dyadic context and reciprocal influences within intimate relationships. Intimate relationships entail mutual processes, where each partner's abusive experiences can affect the partner's marital quality. In this study, we aimed to examine whether self-compassion is an underlying factor in the dyadic associations between CM and one's own and one's partner's marital quality. A convenience sample of 115 heterosexual couples completed self-report questionnaires. Utilizing an actor-partner interdependence model, we found partial support for our hypotheses, indicating that each partner's CM was indirectly associated with their own marital quality through their self-compassion. However, CM did not significantly impact their partner's marital quality through self-compassion. These findings contribute to the existing evidence supporting the mediating role of self-compassion as a transdiagnostic protective factor associated with increased marital quality for individuals with a history of CM. Nevertheless, the results suggest that this mediating effect may be specific to one's own marital quality and may not extend to the partner's marital quality.

Lacticaseibacillus paracasei JY025 fortified milk powder: In vitro digestion characteristics and accelerated storage stability

To clarify the reciprocal influence between the fortified bacterial powder of Lacticaseibacillus paracasei JY025 (LBP) with milk powder matrix during the gastrointestinal digestion and storage period, the digestion characteristics and storage stability of Lacticaseibacillus paracasei JY025 fortified milk powder (LFMP) were explored in this study by the in vitro simulated digestion and the accelerated storage. The results showed that the milk powder matrix significantly improved the survival of JY025 during the simulated digestion (the highest improvement of 27%) and storage period (the highest improvement of 37%), which suggests the milk powder matrix can be an effective strategy to enhance the viability of probiotics during the digestion and storage period. Moreover, the digestion characteristics and the physicochemical properties of the milk powder matrix were changed due to the fortified LBP during the simulated digestion and storage period. The fortified LBP decreased the particle size of milk powder digest and promoted the hydrolysis of milk protein during digestion due to the effect of both maltodextrin (wall material) and bacteria. The fortified LBP also increased the particle size of milk powder matrix and decreased the Maillard reaction of milk powder matrix during the storage period, which is closely related to the storage condition.

Parsing the Interactive Construction of Crisis Memory on Social Media: From a Memory-Agenda Perspective

ABSTRACT This study applied agenda-setting and agenda-building theories to explore the interactive memory agendas facilitated by social media. Focusing on the crisis memory of SARS constructed on Chinese social media (Weibo) during COVID-19, two competing approaches (top-down versus bottom-up) to crisis memory construction were empirically tested. A content analysis was first conducted to identify various crisis memory narratives, and then, rank-order analysis, cross-lagged correlation analysis, and multiple regression quadratic assignment procedure were performed to evaluate the reciprocal influences of crisis memory agendas of the second level (narrative salience) and the third level (narrative network) among different users. Findings show reciprocal influences among certain users’ memory-agendas in constructing crisis memory: media users showed influences on publics in terms of crisis memory agendas of both levels, while this crisis memory construction online also follows a bottom-up direction.

Influence of reciprocal financial resources on shrimp fishers' income sources in Southern Nigeria

The study examines reciprocal financial relationships' influence on shrimp fishers' income sources and their motivation in Rivers State, Nigeria, fishing communities. A mixed methods design was employed using a semi-structured questionnaire, interview guide and checklist to collect data from 125 shrimp fishers and 20 Key informants. Data on shrimp fishers' financial contributions were subjected to UCINET 6.647 Net draw to generate a sociogram. Fishers' income sources and motivating factors were subjected to content analysis and multiple regression. The results showed that shrimp fishers in Rivers State pay dues, contributions and donations to obtain revolving loans from their network and receive remittances from relatives. The sums of money are invested in fishing equipment and off-fishing ventures. 44% of fishers relied on remittances and loans for investment. However, enabling institutional framework and support from external agencies are motivating factors to join a social network which aims at improving income sources among shrimp fishers in line with Sustainable Development Goals 16 and 17. Shrimp fishers who engage in a reciprocal financial relationship have their income sources improved by diversifying into off-fishing ventures. The study recommends that Shrimp fishers register as cooperatives to attract more support from government and donor agencies.

Lung cancer, comorbidities, and medication: the infernal trio.

Most patients with lung cancer are smokers and are of advanced age. They are therefore at high risk of having age- and lifestyle-related comorbidities. These comorbidities are subject to treatment or even polypharmacy. There is growing evidence of a link between lung cancer, comorbidities and medications. The relationships between these entities are complex. The presence of comorbidities and their treatments influence the time of cancer diagnosis, as well as the diagnostic and treatment strategy. On the other hand, cancer treatment may have an impact on the patient's comorbidities such as renal failure, pneumonitis or endocrinopathies. This review highlights how some comorbidities may have an impact on lung cancer presentation and may require treatment adjustments. Reciprocal influences between the treatment of comorbidities and anticancer therapy will also be discussed.

Investigating the network structure and causal relationships among bridge symptoms of comorbid depression and anxiety: A Bayesian network analysis.

The network analysis method emphasizes the interaction between individual symptoms to identify shared or bridging symptoms between depression and anxiety to understand comorbidity. However, the network analysis and community detection approach have limitations in identifying causal relationships among symptoms. This study aims to address this gap by applying Bayesian network (BN) analysis to investigate potential causal relationships. Data were collected from a sample of newly enrolled college students. The network structure of depression and anxiety was estimated using the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) Scale measures, respectively. Shared symptoms between depression and anxiety were identified through network analysis and clique percolation (CP) method. The causal relationships among symptoms were estimated using BN. The strongest bridge symptoms, as indicated by bridge strength, include sad mood (PHQ2), motor (PHQ8), suicide (PHQ9), restlessness (GAD5), and irritability (GAD6). These bridge symptoms formed a distinct community using the CP algorithm. Sad mood (PHQ2) played an activating role, influencing other symptoms. Meanwhile, restlessness (GAD5) played a mediating role with reciprocal influences on both anxiety and depression symptoms. Motor (PHQ8), suicide (PHQ9), and irritability (GAD6) assumed recipient positions. BN analysis presents a valuable approach for investigating the complex interplay between symptoms in the context of comorbid depression and anxiety. It identifies two activating symptoms (i.e., sadness and worry), which serve to underscore the fundamental differences between these two disorders. Additionally, psychomotor symptoms and suicidal ideations are recognized as recipient roles, being influenced by other symptoms within the network.

The spatio-temporal evolution and transformation mode of human settlement quality from the perspective of “production-living-ecological" spaces--a case study of Jilin Province

Amidst rapid industrialization and urbanization, urban and rural human settlements have witnessed marked transformations, each exhibiting distinct developmental trajectories and challenges. Utilizing the “Production-Living-Ecological" spatial theory within territorial planning, this study devises a comprehensive evaluation system for human settlement quality. It delineates the evolution of human settlement quality across 47 counties (districts) in Jilin Province from 1999 to 2020, elucidates the interplay among the three aforementioned dimensions, and identifies the prevailing modes of human settlement transformation. Key findings include: (1) Jilin Province has seen significant enhancements in human settlement quality. Notable shifts in this quality occurred in 2006 and 2015. The synergy and reciprocal influences among the production, living, and ecological dimensions have intensified, with coordination continually advancing. (2) Human settlement quality varies with higher levels in the east and south and lower levels in the west and north in Jilin Province, indicating a spatial clustering pattern. Living and ecological conditions are generally better in the east compared to the west, with noticeable economic-environmental mutual constraints in the west. (3) Given a certain socio-economic development threshold, the trajectory of human settlement quality sketches an overarching “S"-shaped growth pattern. This can be categorized into the first phase of fluctuation, followed by the second phase of significant growth and the third phase of slowing growth. This research furnishes foundational insights for fostering green, low-carbon human settlements and promotes the exploration of harmonious interactions between humans and nature, particularly within the ambit of carbon peak and neutrality objectives.

Transition to grandparenthood and early retirement in midlife

ABSTRACT This paper aims to capture the interrelationship between two life transitions linking the generation of elderly parents and their adult children: early retirement and the transition to (grand)parenthood. A (grand)parents’ early retirement might be driven by the need to care for a grandchild. Conversely, the transition of their adult children into parenthood might be shaped by the availability of flexible, reliable, and affordable childcare provided by retired (grand)parents. Employing an event history approach, we examine the reciprocal influence that the birth of the first grandchild and early retirement have in midlife. Our study focuses on gender and socio-economic differences drawing on the SHARE multi-country dataset. Results show that becoming a grandparent increases the chances of early retirement for both men and women, slightly more among grandmothers than grandfathers. Among new grandfathers, those with higher education are more likely to go into early retirement compared to their less-educated counterparts. Early retirement, on the contrary, does not predict grandparenthood in a significant way, though there is a relatively higher chance of becoming a grandfather if the person who retired is highly educated.

IGF-1R mediates crosstalk between nasopharyngeal carcinoma cells and osteoclasts and promotes tumor bone metastasis

BackgroundNasopharyngeal carcinoma (NPC) poses a significant health burden in specific regions of Asia, and some of NPC patients have bone metastases at the time of initial diagnosis. Bone metastasis can cause pathologic fractures and pain, reducing patients' quality of life, and is associated with worse survival. This study aims to unravel the complex role of insulin-like growth factor 1 receptor (IGF-1R) in NPC bone metastasis, offering insights into potential therapeutic targets.MethodsWe assessed IGF-1R expression in NPC cells and explored its correlation with bone metastasis. Experiments investigated the impact of osteoclast-secreted IGF-1 on the IGF-1R/AKT/S6 pathway in promoting NPC cell proliferation within the bone marrow. Additionally, the reciprocal influence of tumor-secreted Granulocyte–macrophage colony-stimulating factor (GM-CSF) on osteoclast differentiation and bone resorption was examined. The effects of IGF-1 neutralizing antibody, IGF-1R specific inhibitor (NVP-AEW541) and mTORC inhibitor (rapamycin) on nasopharyngeal carcinoma bone metastasis were also explored in animal experiments.ResultsElevated IGF-1R expression in NPC cells correlated with an increased tendency for bone metastasis. IGF-1, secreted by osteoclasts, activated the IGF-1R/AKT/S6 pathway, promoting NPC cell proliferation in the bone marrow. Tumor-secreted GM-CSF further stimulated osteoclast differentiation, exacerbating bone resorption. The IGF-1 neutralizing antibody, NVP-AEW541 and rapamycin were respectively effective in slowing down the rate of bone metastasis and reducing bone destruction.ConclusionThe intricate interplay among IGF-1R, IGF-1, and GM-CSF highlights potential therapeutic targets for precise control of NPC bone metastasis, providing valuable insights for developing targeted interventions.

The development of visual cognition: The emergence of spatial congruency bias

AbstractIn adults, spatial location plays a special role in visual object processing. People are more likely to judge two sequentially presented objects as being identical when they appear in the same location compared to in different locations (a phenomenon referred to as Spatial Congruency Bias [SCB]). However, no comparable Identity Congruency Bias (ICB) is found, suggesting an asymmetric location‐identity relationship in object binding. What gives rise to this asymmetric congruency bias? This paper considered two possible hypotheses. Hypothesis 1 suggests that the asymmetric congruency bias results from an inherently special role of location in the visual system. In contrast, Hypothesis 2 suggests that the asymmetric congruency bias is a product of development, reflecting people's experience with the world. To distinguish the two hypotheses, we tested both adults’ and 5‐year‐old children's SCB and ICB by Identity Judgment Experiments and Spatial Judgment Experiments, respectively. The study found that adults only exhibited a SCB, but no ICB. However, young children exhibited both SCB and ICB, suggesting a symmetric congruency bias and reciprocal influences between location and identity in early development. The results indicate that the asymmetric location‐identity relationship develops as object identity's influence on location gets pruned away, while location's influence on identity is preserved, possibly due to people's gained experiences with regularities of the world.Research Highlights Adults exhibit Spatial Congruency Bias—an asymmetric location‐identity relationship with location biasing their judgment of object identities, but not vice versa. Asymmetric congruency bias may result from an inherently special role of location in visual system (Hypothesis 1) or accumulated experiences with the world (Hypothesis 2). To distinguish the two hypotheses, the study investigated the Spatial Congruency Bias and Identity Congruency Bias in both adults and 5‐year‐old children. Unlike adults who exhibited only Spatial Congruency Bias, 5‐year‐old children exhibited both Spatial Congruency Bias and Identity Congruency Bias.

How Game Ecology Drives Player Choices in Strategy Video Games: An Environmental Determinism Perspective

Background Recent years have witnessed increasing attention on the study of game ecology, the virtual environments, and underlying mechanics within games. Yet, these studies often focus on the active role that players have in changing game ecology, while overlooking the reciprocal influence between game ecology and players. Methods This study investigates the potential impact of game ecology on player choices from an environmental determinism perspective—the development of humanity is shaped by the physical environment. This new perspective is substantiated by a case study of two strategy games, Sid Meier's Civilization VI and Humankind, using an immersive-participatory method to analyze their game mechanics. Results This study identifies four major forms of game mechanics that use game ecology to influence player choices: spatial constraints, movement modifiers, uncommon events, and dynamic indexes. Discussion This study discusses how the identified game mechanics reflect environmental determinism and contrast with the conventional ideology of cultural determinism. Additionally, environmental determinism in video games, derived from a broader social background, is constantly evolving into new forms. Conclusion This study introduces a new perspective of environmental determinism for analyzing the interaction between game ecology and players. This approach has the potential to offer valuable insights into guiding future game design and research endeavors.

Fully understanding the impact of the human retrotransposon L1 requires that each of ∼500,000 L1 copies be evaluated as a potentially unique genomic entity. In this issue of Cell Genomics, Lanciano etal.1 strive toward this goal, illuminating the reciprocal regulatory influence between individual L1s and their genomic integration sites.

Unraveling the interplay between inflammation and stem cell mobilization or homing: Implications for tissue repair and therapeutics.

Inflammation and stem cell mobilization or homing play pivotal roles in tissue repair and regeneration. This review explores their intricate interplay, elucidating their collaborative role in maintaining tissue homeostasis and responding to injury or disease. While examining the fundamentals of stem cells, we detail the mechanisms underlying inflammation, including immune cell recruitment and inflammatory mediator release, highlighting their self-renewal and differentiation capabilities. Central to our exploration is the modulation of hematopoietic stem cell behavior by inflammatory cues, driving their mobilization from the bone marrow niche into circulation. Key cytokines, chemokines, growth factors, and autophagy, an intracellular catabolic mechanism involved in this process, are discussed alongside their clinical relevance. Furthermore, mesenchymal stem cell homing in response to inflammation contributes to tissue repair processes. In addition, we discuss stem cell resilience in the face of inflammatory challenges. Moreover, we examine the reciprocal influence of stem cells on the inflammatory milieu, shaping immune responses and tissue repair. We underscore the potential of targeting inflammation-induced stem cell mobilization for regenerative therapies through extensive literature analysis and clinical insights. By unraveling the complex interplay between inflammation and stem cells, this review advances our understanding of tissue repair mechanisms and offers promising avenues for clinical translation in regenerative medicine.

Frequency of Physical Activity in Acute or Chronic Smoker among General Population of Karachi - A Cross-Sectional Study

Background: This research aims to evaluate the frequency of physical activity among acute or chronic smokers in Karachi's general population, recognizing the reciprocal influence between smoking and physical activity on overall health. Assessing exercise frequency among smokers is crucial, considering the commonly observed association between smoking and declining bodily functions, making it pivotal for comprehensive health assessment. Methods: In this study, a cross-sectional survey involved 316 healthy adults aged 15-69 years, utilizing convenience sampling is used for diverse demographic representation. Data on demographic details, smoking status, and physical activity levels were collected through the International Physical Activity Questionnaire (IPAQ). The subsequent analysis, conducted using SPSS version 0.22, aimed to scrutinize the impact of smoking on participants' physical activity. Results: Among the participants, a majority (76.9%) held jobs with varying physical activity levels. For transportation, nearly all employed modes showed varying physical activity intensities, with 59.8% reporting low, 25.3% moderate, and 14.9% vigorous activity levels. Engagement in household chores and family care displayed diverse physical activity levels: 66.5% reported low, 24.1% moderate, and 9.1% vigorous activities. Similar trends were observed for house maintenance and family care, with 69.0% reporting low, 14.6% moderate, and 16.5% vigorous activities. Conclusion: The study indicates that smokers participate in physical activity less frequently, underscoring the need for heightened attention to their exercise habits. These findings underscore the importance of tailoring health strategies for smokers and examining lifestyle factors influencing their physical well-being. Keywords: Physical Activity, METs, Smoking, Well-being.

Reciprocal Path Model of Autonomous Motivation and Motivational Regulation: Socially Shared Regulation in Intellectual Group Activities

Self- and social regulation are widely expected to increase autonomous motivation; however, few empirical studies have examined the reciprocal influences of autonomous motivation and motivational regulation. This study examined the reciprocal path model between autonomous motivation and three modes of motivational regulation (self-, co-, and socially shared regulation) in intellectual group activities by comparing university students with working adults. The participants were 181 university students and 295 working adults who completed an online questionnaire consisting of psychological measurements. With respect to autonomous motivation and the three modes of motivational regulation, a bidirectional model of university students and working adults was established and statistically analyzed on the basis of two time points of data, one month apart (T1 and T2). The hypothesized path model had a good fit through a multi-group structural equation modeling analysis. Autonomous motivation at T1 positively predicted socially shared regulation, co-regulation, and self-regulation at T2, one month later, for both groups. However, the three modes of regulation did not positively or significantly predict autonomous motivation in either group. Considering the reciprocal influences of autonomous motivation and motivational regulation, we discuss the necessity of implementing these practices in universities and workplaces.
