Recent Advances in Nanoenzymes Based Therapies for Glioblastoma: Overcoming Barriers and Enhancing Targeted Treatment.

Glioblastoma multiforme (GBM) is a highly aggressive and malignant brain tumor originating from glial cells, characterized by high recurrence rates and poor patient prognosis. The heterogeneity and complex biology of GBM, coupled with the protective nature of the blood-brain barrier (BBB), significantly limit the efficacy of traditional therapies. The rapid development of nanoenzyme technology presents a promising therapeutic paradigm for the rational and targeted treatment of GBM. In this review, the underlying mechanisms of GBM pathogenesis are comprehensively discussed, emphasizing the impact of the BBB on treatment strategies. Recent advances in nanoenzyme-based approaches for GBM therapy are explored, highlighting how these nanoenzymes enhance various treatment modalities through their multifunctional capabilities and potential for precise drug delivery. Finally, the challenges and therapeutic prospects of translating nanoenzymes from laboratory research to clinical application, including issues of stability, targeting efficiency, safety, and regulatory hurdles are critically analyzed. By providing a thorough understanding of both the opportunities and obstacles associated with nanoenzyme-based therapies, future research directions are aimed to be informed and contribute to the development of more effective treatments for GBM.

Variability and dynamics of patriotic attitudes of Russians in the context of Special military operation

The article presents the results of a study of the features of socio-political dispositions characteristic of moderate and convinced types of patriotic attitudes. Additionally, an analysis of the dynamics of changes in the ratio of the shares of both types of patriotism in 2024 in the context of SMO in comparison with the situation in 2020 was carried out. The empirical basis of the study was data from a mass survey of the population of the Russian Federation conducted by the Institute of Sociology of FCTAS in February-March 2024 on a representative all-Russian sample. The sample size is 2000 respondents. For comparison, data from a similar survey in 2020 were used. The criterion for typologizing different variants of patriotism is the quantitative difference in the degree of support for judgments of a civil and protective nature, forming a space of patriotic meanings of emotional, cognitive and behavioral aspects of attitude towards Russia. Based on the results of the analysis of data on the assessment of the degree of agreement with judgments of civil and protective meaning, moderate and convinced types of patriotism were identified, which together make up the system of patriotic attitudes of Russians. An analysis of the interrelationships of each type of patriotism with a wide range of socio-political dispositions has shown that the selected types represent integral symptom complexes of views on the country, its current state and development prospects, significantly differing in their stable trends over time. Such a trend for convinced patriots is a focus on traditionalism, and for moderate patriots – on modernism. A comparison of data on the prevalence of a particular type of patriotism in 2020 with similar data in 2024 allowed us to conclude that if in 2020 the system of patriotic attitudes of Russians was in a stable state with the dominance of modernist trends, then in 2024 there was a “shift” of the entire system of patriotic beliefs to a different quality, but equally stable a state, but already dominated by traditionalist tendencies. In general, it is concluded that the system of patriotic attitudes of Russians is very mobile in terms of activating both civil and protective meanings, which in different socio-political contexts leads either to an increase or decrease in the proportion of supporters of one or another of the studied types in the system as a whole.

Protective Action of Cannabidiol on Tiamulin Toxicity in Humans-In Vitro Study.

The growing awareness and need to protect public health, including food safety, require a thorough study of the mechanism of action of veterinary drugs in consumers to reduce their negative impact on humans. Inappropriate use of veterinary drugs in animal husbandry, such as tiamulin, leads to the appearance of residues in edible animal tissues. The use of natural substances of plant origin, extracted from hemp (Cannabis sativa L.), such as cannabidiol (CBD), is one of the solutions to minimize the negative effects of tiamulin. This study aimed to determine the effect of CBD on the cytotoxicity of tiamulin in humans. The cytotoxic activity of tiamulin and the effect of its mixtures with CBD were tested after 72 h exposure to three human cell lines: SH-SY5Y, HepG2 and HEK-293. Cytotoxic concentrations (IC50) of the tested drug and in combination with CBD were assessed using five biochemical endpoints: mitochondrial and lysosomal activity, proliferation, cell membrane integrity and effects on DNA synthesis. Oxidative stress, cell death and cellular morphology were also assessed. The nature of the interaction between the veterinary drug and CBD was assessed using the combination index. The long-term effect of tiamulin inhibited lysosomal (SH-SY5SY) and mitochondrial (HepG2) activity and DNA synthesis (HEK-293). IC50 values for tiamulin ranged from 2.1 to >200 µg/mL (SH-SY5SY), 13.9 to 39.5 µg/mL (HepG2) and 8.5 to 76.9 µg/mL (HEK-293). IC50 values for the drug/CBD mixtures were higher. Reduced levels of oxidative stress, apoptosis and changes in cell morphology were demonstrated after exposure to the mixtures. Interactions between the veterinary drug and CBD showed a concentration-dependent nature of tiamulin in cell culture, ranging from antagonistic (low concentrations) to synergistic effects at high drug concentrations. The increased risk to human health associated with the presence of the veterinary drug in food products and the protective nature of CBD use underline the importance of these studies in food toxicology and require further investigation.

Causal Relationships Between Gut Microbiota, Metabolites, and Diabetic Nephropathy: Insights from a Two-Sample Mendelian Randomization Analysis.

Previous studies have established a correlation between gut microbiota, metabolites, and diabetic nephropathy (DN). However, the inherent limitations of observational studies, including reverse causality and confounding factors, made this relationship uncertain. In this study, we compiled summary statistics from a genome-wide association study (GWAS) conducted on gut microbiota, metabolites, and DN. We employed a two-sample Mendelian randomization (MR) approach, utilizing inverse variance weighted (IVW), MR-Egger, weighted median, and weighted mode methods. We detected the protective nature of genetically predicted representatives from the family Bacteroidaceae (OR: 0.716, 95% CI: 0.516-0.995, p = 0.046), family Victivallaceae (OR: 0.871, 95% CI: 0.772-0.982, p = 0.026), genus Bacteroides (OR: 0.716, 95% CI: 0.516-0.995, p = 0.046), genus Coprococcus 2 (OR: 0.745, 95% CI: 0.576-0.963, p = 0.025), and genus Lactococcus (OR: 0.851, 95% CI: 0.730-0.992, p = 0.039) against the development of DN. Conversely, we identified a positive correlation between the incidence of DN and entities, such as Phylum Bacteroidetes (OR: 1.427, 95% CI: 1.085-1.875, p = 0.011), class Bacteroidia (OR: 1.304, 95% CI: 1.036-1.641,p = 0.024), order Bacteroidales (OR: 1.304, 95% CI: 1.035-1.641, p = 0.028), genus Catenibacterium (OR: 1.312, 95% CI: 1.079-1.594, p = 0.006), genus Lachnoclostridium (OR: 1.434, 95% CI: 1.129-1.821, p = 0.003), and genus Parasutterella (OR: 1.270, 95% CI: 1.070-1.510, p = 0.006). In our analysis, none of the gut metabolites demonstrated a causal relationship with DN. Our results substantiated the potential causal association between specific gut microbiota and DN. Therefore, our study offers novel insight into the mechanisms underlying DN. This finding provides a theoretical foundation for the future development of targeted strategies for the prevention and treatment of DN.

Navigating Workplace Stigma: Examining the Relationship between Power, Authenticity and Religious Coping among employees in Industrial Sectors

Power dynamics, authenticity, religious coping, and workplace stigma within a socio-economic context in Punjab, Pakistan are explored. The research uses a mix methods design of quantitative surveys and qualitative interviews to gather comprehensive data from 350 professionals, from across different professions. Using quantitative analysis, we found there is a significant negative correlation between power dynamics and authenticity (r = -0.57, p < 0.01), meaning that the more power imbalance individuals experience, the less likely they are to display their true selves in their work environment. In addition, religious coping was shown to mediate the relationship between power dynamics and authenticity (? = 0.42, p < 0.01) suggesting that the use of religious practices can help those to maintain authenticity in the workplace. Second, religious coping was positively correlated with psychological well-being (r = 0.60, p <. 01), even among professionals who reported experiencing workplace stigma. Finally, qualitative findings further explained the protective nature of religious coping, showing how it allows individuals to cope with power hierarchies and to reduce stigma related stress. The need to create authentic workplaces and the impact of religious coping strategies on employee wellbeing are emphasized in this study. Organizations can thus create supportive atmospheres where professionals feel comfortable expressing themselves authentically while accessing psychological resilience by addressing power dynamics and stigma in the workplace.

Anhedonia in flux: Understanding the associations of emotion regulation and anxiety with anhedonia dynamics in a sample with major depressive disorder

Negative rumination and emotion regulation difficulties have been consistently linked with depression. Despite anhedonia—the lack of interest in pleasurable experiences—being a cardinal symptom of depression, emotion regulation of positive emotions, including dampening, are considered far less in the literature. Given that anhedonia may manifest through blunted responses to previously positive or enjoyable experiences, it is vital to understand how different positive emotion regulation strategies impact anhedonia symptom severity and how it can vary or change over time. Moreover, understanding the detrimental or protective nature of positive emotion regulation on anhedonia can aid with future anhedonia-focused treatments. Therefore, the current study examined the temporal association between anhedonia dynamics and two different emotion rumination strategies in response to positive emotions: dampening and positive rumination. Depressed persons (N = 137) completed baseline measures of positive emotion regulation, difficulties regulating negative emotions, and anxiety, and completed ecological momentary assessments three times per day for 90 days regarding their depressive symptoms, including anhedonia. We assessed baseline dampening and amplifying scores to predict anhedonia dynamics through four linear models with interactions. Providing partial support for our hypotheses, results indicate that amplifying positivity is positively associated with fluctuations, instability, and acute changes in anhedonia over the course of 90 days; however, neither dampening, difficulties regulating negative emotions, nor anxiety were related to anhedonia dynamics. The current findings suggest that amplifying positivity may be able to predict changes in anhedonia over time and should further be examined as a potential protective factor of anhedonia.

Research on the Relationship Between Attachment Styles and Mental Health (Depression and Anxiety) among Chinese University Students

Abstract: Mental health problems are becoming more serious globally. Relevant literature suggests that insecure attachment has the potential to lead to a range of mental health problems. And increasing attachment security can greatly improve psychological resilience and overall mental health. In this study, 103 Chinese university students were selected to investigate the relationship between their attachment styles and their mental health, especially depression and anxiety. A structured questionnaire based on the Experiences in Close Relationships Scale (ECR-R) was used to assess participants' attachment-related anxiety and avoidance, and the PHQ-9 and GAD-7 were used to assess mental health indicators. The findings reveal that significant differences in depression and anxiety levels between attachment types. Individuals with secure attachment styles exhibit significantly lower levels of depression and anxiety compared to those with insecure attachment styles, such as preoccupied, dismissive. In addition, attachment-related anxiety and avoidance scores could predict depression and anxiety levels. These results underscore the protective nature of secure attachment and highlight the importance of considering attachment styles in mental health interventions.

Graduate reflections on Community Service: a view of roles in practice

BackgroundIn South Africa, newly qualified physiotherapists transition to the workplace during community service, often in diverse healthcare settings, attending to patients with complex ailments. The transition is complicated by the shortage of rehabilitation personnel, especially in rural and peri-urban areas. While higher education curricula should prepare students for the workplace, the roles and expectations of new therapists remain unclear. Assessing how well current curricula, built around the CanMEDS framework, equip students with the competencies needed for entry-level community service practice will help to improve physiotherapy training practices. This study investigated the experiences of community service physiotherapists to inform curriculum design and graduate outcomes.MethodsA descriptive qualitative study was conducted. Graduates were purposefully sampled during their community service year via a class group contact, with a snowball approach to recruit diverse participants. Semi-structured interviews were conducted over MS Teams, recorded, and transcribed. Reflexive deductive coding was used to interpret the data, which was analysed around the CanMEDS roles and graduate outcomes, as well as curriculum constraints and enablers to the workplace transition.ResultsTen community service physiotherapists placed in five different provinces participated. Most identified strongly with their core role as clinicians and felt prepared in terms of clinical skills. However, aspects of roles linked to advocacy, leadership, and professionalism were more complex to navigate. The contexts of placements and the nuances of how the healthcare system operated in each province impacted their experience.ConclusionThe study highlighted varied readiness levels among community service physiotherapists. While many felt competent in specific clinical tasks, there are significant gaps in their preparation for broader community practice challenges. Participants noted their undergraduate training adequately prepared them for the clinician role but not for roles integrating collaboration, communication, patient and professional advocacy. Quality clinical placements and the role of educators were crucial, yet the protective nature of these placements limited exposure to real-world scenarios. Insufficient mentorship and support contributed to feelings of isolation. To enhance preparedness, the curriculum should integrate more experiences addressing real-world challenges, which value multiple competencies and outcomes. Future research should examine the development of context-appropriate competency frameworks and long-term effects of community service on career development.

Pseudoaneurysm of the Lingual Artery in a Patient With Facial Trauma From Gunshot Wounds.

A pseudoaneurysm is an abnormal dilatation within the wall of a blood vessel due to the formation of a hematoma in the vessel wall after vessel injury. Because of the protective nature of the facial skeleton and the deep location of the lingual artery, the lingual artery pseudoaneurysm is rare. The authors report a case of a 20-year-old male who suffered multiple gunshot wounds, including to the mouth, presenting with immediate life-threatening injuries. On hospital day 1, otolaryngology performed debridement of the mandible, retrieval and removal of bullet fragments, intermaxillary fixation, external fixation of the mandible, intra-oral laceration repair, repair of tongue laceration, and tracheotomy revision. On postoperative day 15, the otolaryngology service was called for the abrupt onset of major oral cavity bleeding. computed tomography-angiogram detected a pseudoaneurysm of the lingual artery and was successfully treated with endovascular coil embolization.

Advancing Anti-Biofilm Strategies: Innovations to Combat Biofilm-Related Challenges and Enhance Efficacy.

Biofilms are complex communities of microorganisms that can cause significant challenges in various settings, including industrial processes, environmental systems, and human health. The protective nature of biofilms makes them resistant to traditional anti-biofilm strategies, such as chemical agents, mechanical interventions, and surface modifications. To address the limitations of conventional anti-biofilm methods, researchers have explored emerging strategies that encompass the use of natural compounds, nanotechnology-based methods, quorum-sensing inhibition, enzymatic degradation, and antimicrobial photodynamic/sonodynamic therapy. There is an increasing focus on combining multiple anti-biofilm strategies to combat resistance and enhance effectiveness. Researchers are continuously investigating the mechanisms of biofilm formation and developing innovative approaches to overcome the limitations of conventional anti-biofilm methods. These efforts aim to improve the management of biofilms and prevent infections while preserving the environment. This study provides a comprehensive overview of the latest advancements in anti-biofilm strategies. Given the dynamic nature of this field, exploring new approaches is essential to stimulate further research and development initiatives. The effective management of biofilms is crucial for maintaining the health of industrial processes, environmental systems, and human populations.

Effective distinction of lipid microbubbles in pediatric bone phantom using a machine learning approach

This study investigates the ability to detect microbubble attenuation signals across a bone phantom (meant to mimic a pediatric femur) using ultrasound and machine learning. Lipid microbubbles were fabricated and injected through a hollow capillary fiber (200 μm) in a water tank attached to a syringe pump. Focused ultrasound (1.1 MHz, 1–10 MPa, 500 pulses) was applied to the flowing bubbles in the presence or absence of a custom 3-D-printed bone phantom. A co-aligned passive cavitation detector (PCD) captured the reflected ultrasound signals. Ultrasound signals were compared using Fast Fourier Transform (FFT) to process the data. Eleven spectral features were extracted and used as the basis for machine learning algorithms. The results confirm that despite strong signal interference from the bone, machine learning can effectively distinguish the presence of lipid microbubbles. The study signifies the potential of lipid microbubbles for targeted drug delivery to bone marrow using PCD, a method often deemed challenging due to the hard barrier posed by bone structures. This method has important implications for medical treatments such as chemotherapy or gene therapy, which often struggle to reach the bone marrow due to its protective nature.

The regulatory and protective nature of administrative and procedural legal relations

The article attempts to analyze administrative and procedural legal relations from the point of view of characterizing the ratio of their regulatory and protective nature.The methodological basis of the article is dialectical, formal-logical methods, formal-legal method and method of interpretation of law.The paper calls into question the possibility of using the protective legal relationship as a basis for distinguishing procedural and material legal relations. The author argues that not all activities and actions that have a protective nature and are carried out in the process of public administration are procedural in nature. The assumption that the emergence of a legal process is connected not only with a protective legal relationship arising from noncompliance with obligations or the occurrence of other situations entailing the use of coercive measures, but also in order to ensure respect for the rights of participants in the process from abuse of power by persons making both interim and final procedural decisions is made. Ensuring the rights of participants in the administrative process is carried out by establishing specific administrative procedural actions, deadlines, administrative procedural decisions, procedural grounds for their adoption, etc. The legal process, including the administrative process, must be considered from the point of view of establishing the truth in the case, but at the same time guarantees must be provided that prevent the abuse of power by on the part of the ruling entity and the right on the part of all participants in the process. At the same time, administrative procedural regulation is aimed not only at establishing legal facts, comprehensiveness, completeness and objectivity of the consideration of an administrative case, but also at protecting the rights of persons involved in the case and ensuring their duties. Hence, the protective nature of administrative and procedural legal relations does not follow from the main substantive legal relationship, but from the corresponding purpose of protecting and ensuring the legitimate procedural rights and obligations of participants in the administrative process.Administrative and procedural legal relations, realizing the regulatory function of law, are formed on the basis of regulatory norms that provide for administrative and procedural rights and obligations of relevant subjects in the consideration and resolution of administrative cases. In addition to the fact that administrative and procedural legal relations are regulatory, they also have a law enforcement character. The regulatory function of administrative and procedural law is expressed in the establishment of not only administrative and procedural actions that should (can) be committed by the subjects of administrative and procedural legal relations when initiating, establishing circumstances, considering an administrative case, but also in their specific sequence, timing of commission, as well as types of administrative and procedural decisions, etc. The protective function of administrative and procedural law is to protect the administrative and procedural rights and interests of all participants in legal relations.Based on the above, the author comes to the conclusion that administrative and procedural legal relations are of a regulatory and protective nature.

Potential Penetration of Engineered Nanoparticles under Practical Use of Protective Clothing Fabrics.

The commercial application of engineered nanoparticles (ENPs) has rapidly increased as their unique properties are useful to improve many products. ENPs, however, can pose a major health risk to workers through exposure routes such as inhalation and dermal contact. Research is lacking on the protective nature of lab coats when challenged with ENPs. This study investigated multiwalled carbon nanotubes (CNTs), carbon black (CB), and nano aluminum oxide (Al2O3) penetration through four types of lab coat fabrics (cotton, polypropylene, polyester cotton, and Tyvek). Penetration efficiency was determined with direct reading instruments. The front and back of contaminated fabric swatches were further assessed with microscopy analysis to determine fabric structure with contaminated and penetrated particle morphology and level of fabric contamination. Fabric thickness, porosity, structure, surface chemistry, and ENP characteristics such as shape, morphology, and hydrophobicity were assessed to determine the mechanisms behind particle capture on the four common fabrics. CNTs penetrated all fabrics significantly less than the other ENPs. CNT average penetration across all fabrics was 1.83% compared to 15.74 and 11.65% for CB and Al2O3, respectively. This can be attributed to their fiber shape and larger agglomerates than those of other ENPs. Tyvek fabric was found to be the most protective against CB and Al2O3 penetration, with an average penetration of 0.06 and 0.11%, respectively, while polypropylene was the least protective with an average penetration of 40.36 and 15.77%, respectively. Tyvek was the most nonporous fabric with a porosity of 0.50, as well as the most hydrophobic fabric, explaining the low penetration across all three ENPs. Polypropylene is the most porous fabric with a porosity of 0.77, making it the least protective against ENPs. We conclude that porosity, fabric structure, and thickness are more important fabric characteristics to consider when discussing particle penetration through protective clothing fabrics than surface chemistry.

Small organic osmolytes accelerate actin filament assembly and stiffen filaments.

Actin filament assembly and mechanics are crucial for maintenance of cell structure, motility, and division. Actin filament assembly occurs in a crowded intracellular environment consisting of various types of molecules, including small organic molecules known as osmolytes. Ample evidence highlights the protective functions of osmolytes such as trimethylamine-N-oxide (TMAO), including their effects on protein stability and their ability to counteract cellular osmotic stress. Yet, how TMAO affects individual actin filament assembly dynamics and mechanics is not well understood. We hypothesize that, owing to its protective nature, TMAO will enhance filament dynamics and stiffen actin filaments due to increased stability. In this study, we investigate osmolyte-dependent actin filament assembly and bending mechanics by measuring filament elongation rates, steady-state filament lengths, and bending persistence lengths in the presence of TMAO using total internal reflection fluorescence microscopy and pyrene assays. Our results demonstrate that TMAO increases filament elongation rates as well as steady-state average filament lengths, and enhances filament bending stiffness. Together, these results will help us understand how small organic osmolytes modulate cytoskeletal protein assembly and mechanics in living cells.

Biochemical and histological alterations induced by UV-328 in the gill tissue of Zebra fish (Danio rerio) and its reversal by Dimethoxy curcumin

The presence of Benzotriazole UV Stabilizer-328 (UV-328) in different biological and natural systems is of fast, regular concern in recent days due to their exuberant use in sunscreens. To learn more about its role of oxidative damage in the gills and to uncover the protective nature of DiMC, we evaluated its sub-lethal toxicity in Zebra fish gill tissue and also evaluated the potential defensive role of Dimethoxy curcumin (DiMC). Grown-up Zebra fish were exposed to 55 µg/L of UV-328 and 50mg/kg of DiMC for four weeks. After the completion of 28 days, gill tissues were dissected out and assessed for their response to oxidative stress, antioxidant enzymes status, and histopathological changes. Our results demonstrated that antioxidant such as glutathione (GSH) levels and the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and Glutathione S-transferase (GST) were all diminished in the gill tissue along with the profound increase in lipid peroxidation (measured as TBARS) in the UV-328-treated group. Histopathological lesions, for instance, inflammatory cell infiltration with a minimal congestion in primary lamellae, diffuse epithelial hyperplasia and fusion of secondary lamellae, multifocal mucus cell hyperplasia were seen in the UV-328-treated gill tissue of Zebra fish. The UV-328-induced oxidative, biochemical, and histological alterations were almost reverted back to normal in the DiMC enhanced group, suggesting its remediative efficacy against UV-328-induced respirotoxicity. Based on our findings, exposure to UV-328, even at a low level, could be toxic, causing oxidative stress, antioxidant depletion, and pathological gill damage in Zebra fish. And these alterations were almost recuperated in DiMC supplemented group which signifies its protective influence against UV-328 toxicity. Keywords: UV-328; Oxidative stress; Antioxidants; Histopathology; Zebra fish

Evolution of retrocopies in the context of HUSH silencing

Retrotransposition is one of the main factors responsible for gene duplication and thus genome evolution. However, the sequences that undergo this process are not only an excellent source of biological diversity, but in certain cases also pose a threat to the integrity of the DNA. One of the mechanisms that protects against the incorporation of mobile elements is the HUSH complex, which is responsible for silencing long, intronless, transcriptionally active transposed sequences that are rich in adenine on the sense strand. In this study, broad sets of human and porcine retrocopies were analysed with respect to the above factors, taking into account evolution of these molecules. Analysis of expression pattern, genomic structure, transcript length, and nucleotide substitution frequency showed the strong relationship between the expression level and exon length as well as the protective nature of introns. The results of the studies also showed that there is no direct correlation between the expression level and adenine content. However, protein-coding retrocopies, which have a lower adenine content, have a significantly higher expression level than the adenine-rich non-coding but expressed retrocopies. Therefore, although the mechanism of HUSH silencing may be an important part of the regulation of retrocopy expression, it is one component of a more complex molecular network that remains to be elucidated.

Artificial Intelligence in Urology: Application of a Machine Learning Model to Predict the Risk of Urolithiasis in a General Population.

This research presents our application of artificial intelligence (AI) in predicting urolithiasis risk. Previous applications, including AI for stone disease, have focused on stone composition and aiding diagnostic imaging. AI applications centered around patient-specific characteristics, lifestyle considerations, and diet have been limited. Our study comprised a robust sample size of 976 Chilean participants, with meticulously analyzed demographic, lifestyle, and health data through a comprehensive questionnaire. We developed a predictive model using various classifiers, including logistic regression, decision trees, random forests, and extra trees, reaching high accuracy (88%) in identifying individuals at risk of kidney stone formation. Key protective factors highlighted by the algorithm include the pivotal role of hydration, physical activity, and dietary patterns that played a crucial role, emphasizing the protective nature of higher fruit and vegetable intake, balanced dairy consumption, and the nuanced impact of specific protein sources on kidney stone risk. In contrast, identified risk factors encompassed gender disparities with males found to be 2.31 times more likely to develop kidney stones than females. Thirst and self-perceived dark urine color emerged as strong predictors, with a significant increase in the likelihood of stone formation. The development of predictive tools with AI, in urolithiasis management signifies a paradigm shift toward more precise and personalized health care. The algorithm's ability to process extensive datasets, including dietary habits, heralds a new era of data-driven medical practice. This research underscores the transformative impact of AI in medical diagnostics and prevention, paving the way for a future where health care interventions are not only more effective but also tailored to individual patient needs. In this case, AI is an important tool that can help patients stay healthy, prevent diseases, and make informed decisions about their overall well-being.

Calling on Hope: Examining the Protective Nature of Hope on Mental Health Risk Factors in Black Women

Feelings of defeat and entrapment are significant risk factors for various mental health conditions such as depression, anxiety, PTSD, and suicidality. However, limited studies have intentionally examined these constructs exclusively within a sample of Black women. The current study aims to investigate whether the endorsement of hope can serve as a protective factor against feelings of defeat and entrapment among Black women. About 266 ( Mage = 34) cisgender African American/Black women were surveyed, and results indicated that hope negatively moderated the relationship between defeat and entrapment, suggesting that hope served as a protective factor by weakening the relationship between defeat and entrapment. Future research and clinical implications are discussed.

In the Mood for Food: Monotony, Boredom and Snacking During Work

Although unhealthy snacking may have detrimental consequences for employee health and organizational outcomes, the role of working conditions on snacking still remains poorly understood. Drawing from optimal arousal theory, we propose and test a conceptual model that explains how under-stimulating conditions of job monotony increase unhealthy snacking behaviors during work due to experienced boredom. Given that individual differences play an important role for eating behaviors, we further propose that trait mindfulness may moderate the relationship between daily work-related boredom and unhealthy snacking, as it can decrease impulsive reactions to boredom. Results from diary data across two workweeks (N = 105) confirmed the positive effect of daily job monotony on unhealthy snacking through work-related boredom. Supplementary analyses revealed that these results persisted above and beyond over-stimulating work stressors (daily workload) and alternative mediators (daily negative affect). Surprisingly, the protective nature of trait mindfulness was not confirmed by our results. The implications of our findings are discussed for theory and practice.
