This study examines the impact of integrating Turon martial arts elements into wrestling training sessions on students’ physical fitness indicators. The research was conducted during the 2024–2025 academic year with the participation of 19 university students. Physical fitness tests were carried out at the beginning of the academic year (September) and during interim control (May), and the results were comparatively analyzed.

The findings revealed positive dynamics in strength, speed-strength abilities, and agility. Improvements were observed in pull-ups, push-ups, standing long jump, abdominal strength exercises, and shuttle running performance. The study confirms that integrating Turon martial arts elements into wrestling training contributes to the comprehensive development of students’ physical fitness and enhances training effectiveness.

Mentorship has long been recognized as one of the most powerful determinants of professional development, career satisfaction, and scholarly productivity in academic medicine. Yet despite more than four decades of research documenting the benefits of mentoring relationships, academic medicine continues to face persistent inequities in recruitment, retention, advancement, and well-being, particularly among individuals who occupy marginalized or multiply marginalized social positions. This paradox suggests that mentorship cannot be fully understood or optimized without attention to broader social, cultural, and structural forces that shape how mentoring relationships are formed, enacted, and experienced. Drawing on a comprehensive body of scholarship on mentoring in academic medicine and integrating it with contemporary theories of intersectionality, cultural humility, cultural safety, and health equity, this article develops an original, theoretically unified, and empirically grounded framework for understanding mentorship as both a professional development mechanism and a site of power, identity negotiation, and institutional reproduction.

Using an integrative narrative synthesis approach grounded in the foundational mentoring literature of Roch, Palepu and colleagues, Pololi and colleagues, Allen and colleagues, Cameron and Blackburn, and others, alongside the intersectionality and equity-focused work of Collins, Crenshaw, Bowleg, Jones, Braveman, Curtis, Hook, and Wilkins, this study moves beyond a narrow focus on dyadic mentor–mentee relationships. Instead, it conceptualizes mentorship as a multilayered social process embedded within historically structured systems of race, gender, class, professional hierarchy, and institutional culture. The methodology involves a theoretically informed qualitative synthesis in which mentoring functions, roles, and outcomes identified in the medical education literature are reinterpreted through an intersectional lens to illuminate how advantages and disadvantages are differentially distributed.

The results of this analysis demonstrate that while mentorship consistently produces positive career outcomes, including increased productivity, career clarity, and professional confidence, these benefits are not evenly accessible. Informal mentoring networks, which are often the most powerful sources of sponsorship and career advancement, disproportionately favor those who already resemble institutional norms of authority and legitimacy. At the same time, mentees from marginalized backgrounds often experience mentoring relationships that are simultaneously supportive and constraining, shaped by cultural misunderstanding, implicit bias, and unequal power dynamics. The integration of cultural humility and cultural safety frameworks reveals that effective mentorship in diverse academic environments requires not only technical guidance but also a reflexive, justice-oriented orientation toward difference, power, and historical context.

In discussion, the article argues that mentorship must be reconceptualized as a form of institutional practice rather than merely an interpersonal relationship. Such a reconceptualization carries profound implications for faculty development, leadership training, and organizational accountability. By embedding intersectionality and equity into the design, evaluation, and everyday practice of mentoring, academic medical centers can transform mentorship from a mechanism that often reproduces inequality into one that actively disrupts it. The article concludes by outlining a set of theoretically grounded and empirically supported principles for building mentoring systems that promote both excellence and justice in academic medicine.

This article examines the role of iron and copper coordination compounds in modern medicine and pharmacology as of 2026. It substantiates the need to transition from inorganic metal salts to complex compounds with organic ligands to increase bioavailability and reduce toxicity. The mechanisms of action of modern drugs, including ferroptosis and cuproptosis , are described, as well as the use of metal complexes in the treatment of anemia, oncology, diagnostics (MRI and PET-CT), and regenerative medicine. Particular attention is paid to innovative delivery technologies, such as liposomal formulations and the use of AI in compound modeling.

This scientific review expands the understanding of the mechanisms of colonization resistance of the vaginal mucosa by lactobacilli of the female reproductive tract, which are based on adhesion to epithelial cells, the production of lactic acid, hydrogen peroxide and bacteriocins. Changes in these properties of the vagina lead to a disruption of the vaginal normocenosis, which can lead to the onset of gynecological diseases such as colpitis, cervical intraepithelial neoplasia, and cervical cancer.

This article examines current clinical and laboratory approaches to diagnosing gonorrhea in women, taking into account the epidemiological, microbiological, and clinical characteristics of the disease.

Objective: The current advancements in digital workflows and artificial intelligence in estimating tissue overload, restoration failures, and longevity predictions have increased the biomechanical precision in the field of esthetic dental rehabilitation and aim to analyze and compare the biomechanical parameters of aesthetic dental rehabilitation using generative neural networks versus traditional clinician-driven methods.

Methodology: A narrative review from 2015 to 2025 examined the PubMed, Scopus, Web of Science, IEEE Xplore, and Cochrane library for studies in English concerning finite element, laboratory, clinical, and AI studies that include the outcomes of biomechanics.

Results: GNN assisted planning showed significant biomechanical gains in intricate rehabilitations, especially in multi-unit and implant-supported restorations. Declined peak stresses and more uniform distribution in peri-implant and periodontal structures, improved control of deformations, and thorough reconstruction in more optimized geometries, especially in the stresses or deformations, were noted. The evidence is mostly simulation-based, methodologically heterogeneous, and lacks thorough and sustained clinical validation.

Conclusions: GNN-based planning indicates possible biomechanical advantages, notably less peak stress for complicated dental rehabilitations; however, most evidence is simulation-based. The GNN workflow's clinical implementation requires biomechanical principles and relies on predictive analysis, explainable AI, and cross-disciplinary substantiation.

This article examines the biochemical and pharmacological aspects of the use of zinc and cobalt coordination compounds in modern medical practice. The relevance of switching from inorganic salts to biocoordination compounds with organic ligands (amino acids, vitamins) to increase the therapeutic index and reduce toxicity is substantiated. The roles of zinc as an immunomodulator and antioxidant, and cobalt as a key component of hematopoiesis, are described. The potential for using these complexes in endocrinology, oncology, and regenerative medicine is analyzed.

B2B and B2C marketing strategies are traditionally seen as variations of the same discipline, differing in the scope of deals and number of stakeholders. However, the psychological mechanisms of influence and decision-making structures in B2B are radically different from B2C. The study analyzes cognitive biases, framing effects, deficit cues in both contexts based on a systematic literature review 2010-2023. B2C decision-making is dominated by quick heuristics and emotional triggers, B2B is characterized by multi-stakeholder consensus and the dominance of perceived risk. Framing effects in B2C are strongest for loss-framed messages, B2B shows resistance to simple loss/gain framing. Scarcity signals in B2C activate impulse purchases, in B2B they are interpreted as a signal of demand or unreliability. Dark patterns fail in B2B through collective evaluation and long-term relationships. The developed application model takes into account stakeholder mapping, evaluation cycle management, trust building through content strategies, and customer lifetime value metrics.

This article analyzes the psychological foundations of the manicure as a self-support ritual and a form of self-affirmation. The relevance of the study is driven by the sustained demand for nail services during periods of crisis and their influence on emotional regulation. The novelty lies in the analytical synthesis of data on manicures, makeup, and cultural-symbolic body codes with a focus on "body extension." The work describes the effects of manicures on mood, relaxation, and vitalization; it examines the differences between salon and independent practices, color coding, the influence of communication with the technician, the sanitary foundations of trust, and the boundaries between care and compulsion. Special attention is paid to salon communication as a condition for enhancing positive experiences. The objective of the work is to identify how manicures influence self-esteem and social behavior. To achieve this, comparative analysis, interpretive generalization of empirical data, content analysis of regulations, and theoretical modeling are employed. Publications and studies on makeup and female grooming practices are examined. The conclusion describes an applied framework for conscious decision-making for clients and technicians. The article will be useful to psychologists, nail service specialists, and researchers of female grooming.
