Background: The effect of inspiratory muscle training on diaphragm muscle thickness (DT) and one repetition maximal (1RM) in professional natural bodybuilders is still unclear. The aim of the study was to investigate the effect of inspiratory muscle training on diaphragm muscle thickness and 1RM in professional natural bodybuilders. Methods: The study comprised a total of 22 athletes who participated in bodybuilding competitions. Each athlete had undergone a minimum of 5 years of training, with a minimum weekly commitment of 5 hours. Participants were randomly divided into two groups: inspiratory muscle training (IMT) and control (CON). The CON continued their normal training regime, while the IMT group also performed inspiratory muscle training with a 10% weekly increase by setting the resistance setting of the PowerBreathe (R) Classic device to 40% of the participant's maximum inspiratory pressure (MIP). Prior to and during the 4-week training period, 1RM bench press measurements and diaphragm muscle thickness measurements were obtained. Results: In the comparison of 1RM power values before and after training, it was determined that the IMT group (%: 11.20) had 6.3% more post-activation performance enhancement compared to the CON group (%: 4.9) (p < 0.001). In the study, it was determined that a higher level of significant post-activation performance enhancement was obtained in the IMT group compared to the CON group in the diaphragm muscle thickness inspiratory phase (DT ins) and ekspiratory phase (DT eks) parameters at 20.36% and 19.46%, respectively. Conclusion: In conclusion, we determined that the addition of progressive loading inspiratory muscle training to preparation programmes in natural bodybuilders will improve diaphragm muscle thickness, 1RM physical performance. In particular, it shows that the diaphragm muscle should be considered not only as a muscle that supports respiration, but also as a muscle that contributes to power generation by optimising intra-abdominal pressure.

Background: The extant research on judo sports has principally concentrated on the physiological effects of training. Conversely, there has been limited attention paid to studies on psychological resilience, self-control, and emotional expression levels. The present study examined the effects of Judo exercises on psychological resilience, self-control, and emotional expression levels in healthy male subjects. Methods: The present study comprised 50 healthy, sedentary male subjects. The subjects were randomly divided into two groups: one group participated in judo training (JT) and the other group served as the control group (CON). The sample sizes for the JT and CON groups were both 25. The JT group underwent judo training, while the CON group maintained their usual lifestyle. The Brief Psychological Resilience Scale, the Multidimensional Brief Self-Control Scale, and the Berkeley Emotion Expression Scale were administered prior to and following the 6-week training period. Results: The study demonstrated that a 6-week judo training regimen exerted a significant effect on the psychological resilience score (e.s. = 1.047, p < 0.001), while no such effect was observed in the Control group (e.s. = 0.0091, p = 0.751). In the context of self-control levels, an effect was observed on the Initiation sub-dimension (e.s. = 1, 739, p < 0.001), yet no effect was found on the Inhibition dimension (e.s. = 0.052, p = 0.892). In the control group, a significant decrease was identified in the Initiation sub-dimension (e.s. = 0, 785, p = 0.001) and Inhibition sub-dimension (e.s. = 1, 861, p < 0.001). The findings indicate that impulse power (e.s. = 0.395) and concealment (e.s. = 0.428) exerted a negligible influence on the emotional expression sub-dimensions. Conversely, psychological resilience (e.s. = 0.886) demonstrated a substantial impact. Conclusions: The judo exercises demonstrated a favorable impact on psychological resilience, self-control, and emotional expression levels in healthy male subjects. The findings of this study may offer significant insights into the impact of judo exercises on psychological resilience, self-control, and emotion expression levels. These findings could serve as a guide for the development of future interventions and program design in the domain of sport psychology.

Apelin is a hormone with lymphangiogenesis potential, associated with tumor growth and lymph node metastasis, and is reported to stimulate tumor vascularization. This study aimed to investigate the response of the apelin hormone in cattle with and without Enzootic Bovine Leukosis (EBL) infection, based on physiological parameters such as breed, age, and body condition score (BCS). A total of 120 Simmental and Montafon cattle of varying ages (<2, 2-8, and >8) and BCS categories (<2, 3-3.5, and >= 4) were included in the study. Serum apelin hormone levels were measured using the ELISA technique in blood samples collected from the neck vein ( Vena jugularis) of the animals. The analysis of mean serum apelin (ng/mL) values revealed that, among EBL-positive cattle, the highest value was 2.77 ng/mL in Simmental cattle aged 2-8 years with a BCS of 3-3.5, while a value of 2.69 ng/mL was observed in Montafon cattle aged >8 years with a BCS of 3-3.5. For EBL-negative cattle, the highest mean serum apelin value was 2.24 ng/mL, recorded in Simmental cattle aged 2-8 years with a BCS of 3-3.5, whereas it was 1.45 ng/mL in Montafon cattle aged >8 years with the same BCS. In conclusion, this study demonstrated for the first time the effect of apelin hormone levels in cattle with or without EBL, depending on physiological parameters such as age, breed, and BCS. It is suggested that the apelin hormone, which is involved in neoplastic lymphocyte cell infiltration in the lymphoreticular tissues of cattle, and plays a role in regulating tumor growth in EBL, a malignant tumor disease, may contribute to eradication programs. Moreover, the evaluated parameters may prove valuable for disease prevention and control strategies.

Introduction: This study examined the associations among ruminative thinking style (RTS), subjective wellbeing (SWB), and cognitive-behavioral physical activity (CBPA) in a sample of 1,326 adolescents (aged 14-18) from sports high schools. Method: Using validated self-report measures, data were analyzed through bootstrapped mediation models. Results: RTS was negatively associated with SWB (beta = -0.1792, p < 0.001), while CBPA showed a partial mediating effect in this relationship (indirect beta = 0.0779, p < 0.001). Discussion: These results suggest that cognitive-behavioral orientations toward physical activity may buffer the negative impact of rumination on wellbeing. Consistent with cognitive-behavioral therapy (CBT) principles, CBPA could provide adolescents with self-regulatory strategies that support mental health. However, the cross-sectional and self-report design, as well as the focus on sports high school students, limit causal inference and generalizability. Future longitudinal and cross-cultural studies are needed to confirm these findings. Overall, the study provides preliminary evidence that CBPA-informed approaches may hold promise for promoting adolescents' mental wellbeing.

Çabas, Meral; Beser, Nazife Ozge; Ayaydin, Hasan; Barut, Abdulkadir; Magazzino, Cosimo
This paper aims to investigate the relationship among green environmental technologies, resource efficiency, population density and ecological footprint in 38 OECD member countries between 2000 and 2019. The Method of Moments Quantile Regression (MMQREG) and Augmented Mean Group (AMG) estimators are used to analyse this relationship. Based on the results, strong evidence of a negative relationship between green environmental technologies, resource efficiency, population density and ecological footprint emerges, suggesting that these factors contribute to environmental improvement in OECD economies. Overall, the findings contribute to a deeper understanding of the complex dynamics among these variables and provide valuable insights for policymakers and stakeholders striving for sustainable environmental management and policy formulation. In this context, countries should develop standard guidelines and best practices on green technologies and resource efficiency, making it easier for sectors to adapt in these areas.

This study investigates the effects of economic freedom sub-components on load capacity factor (LCF) in 12 MENA countries for 2017-2022. The 12 sub-components of the economic freedom index were used as independent variables, and the load capacity factor was used as the dependent variable. In the study, four-panel data models were created using the subcomponents of the economic freedom index, and a two-stage System-GMM was used. According to the study, while property rights reduce the load capacity factor, Judicial Effectiveness increases it. The effect of Government Integrity on the load capacity factor is statistically insignificant. While Government spending negatively affects the load capacity factor, Tax Burden and Fiscal Health are statistically insignificant. Business freedom affects the load capacity factor positively, but monetary freedom affects it negatively. Labour freedom is statistically insignificant. On the other hand, trade freedom and investment freedom have a positive impact on the load capacity factor, while financial freedom has a negative effect.

The research and design of new inhibitors for the treatment of diseases such as Alzheimer's disease and glaucoma through inhibition of cholinesterases (ChEs; acetylcholinesterase, AChE and butyrylcholinesterase, BChE) and carbonic anhydrase enzymes are among the important targets. Here, a series of novel sulfonamide-bearing pyrazolone derivatives (1a-f and 2a-f) were successfully synthesized and characterized by using spectroscopic and analytical methods. The inhibitory activities of these newly synthesized compounds were evaluated both in vitro and in silico for their effect on carbonic anhydrases (hCA I and hCA II isoenzymes) and ChEs. The in vitro studies showed that these novel compounds demonstrated potential inhibitory activity, with K-I values covering the following ranges: 18.03 +/- 2.86-75.54 +/- 4.91 nM for hCA I, 24.84 +/- 1.57-85.42 +/- 6.60 nM for hCA II, 7.45 +/- 0.98-16.04 +/- 1.60 nM for AChE, and 34.78 +/- 5.88-135.70 +/- 17.39 nM for BChE. Additionally, many of these compounds showed promising inhibitory activity, and some showed higher potency than reference compounds. While the in silico studies have also identified the potential binding positions of these compounds, using the crystal structures of hCA I, II, AChE and BChE receptors. The varying affinities demonstrated by these designed compounds for ChEs and hCA isoenzymes show that these compounds could hold promise as potential alternative agents for selectively inhibiting ChEs and hCAs in the treatment of diseases such as Alzheimer's disease and glaucoma.

The processes governing ophiolite formation and evolution remain incompletely understood. The K & imath;z & imath;lda & gbreve; ophiolite, a well-preserved remnant of the Neo-Tethyan oceanic lithosphere in the Anatolian region, southern T & uuml;rkiye, offers critical insights into subduction-related processes and geodynamics. This study presents new element data for mineral and whole-rock samples, combined with Re-Os isotopic compositions of mantle peridotites and associated crustal rocks and extrusives. Petrographic observations identify two distinct groups of peridotites: (1) those with very low modal clinopyroxene, interpreted as highly depleted harzburgites and preserving primary mineral assemblages, and (2) depleted harzburgites containing secondary clinopyroxene with elevated trace element contents, inferred to have crystallized from percolating melts and thus reflecting metasomatic modification. Spinel and orthopyroxene compositions indicate 17-25% degrees of partial melting, with evidence for melting in both garnet and spinel stability fields. However, mineral and whole-rock compositions also record subsequent cryptic and modal metasomatism. Crustal rocks and extrusives exhibit geochemical signatures transitional between fore-arc basalts and boninites, consistent with subduction initiation settings. Variations in Os isotope ratios (187Os/188Os) in crustal rocks further reveal melt-rock interactions and the incorporation of radiogenic Os from subducted oceanic crust. The integration of petrographic, geochemical, and isotopic data supports a four-stage tectonic model for subduction initiation and mantle wedge evolution, consistent with global models proposed for supra-subduction zone (SSZ) ophiolites, particularly those of the Tethyan domain. These findings provide new constraints on mantle melting, metasomatism, and subduction initiation processes and contribute to a broader understanding of SSZ mantle evolution in both regional and global contexts.

Background A limited number of studies have investigated the effects of circadian rhythm-based running exercise interventions on physical fitness in child athletes. This study aimed to investigate the effects of an eight-week morning and evening running program on lower extremity strength, agility and respiratory function in 10-12-year-old male footballers.Methods Participants visited the laboratory three times, with one-day intervals before and after the training program. The assessments included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and the FEV1/FVC ratio. Additionally, agility and functional performance tests (FPTs) were conducted for both the dominant and non-dominant legs.Results The findings indicated that morning running was more effective than evening running in enhancing respiratory function. Morning running also showed superior results in lower extremity strength tests, particularly in the single-leg (SL) and triple-leg (THD) crossover hop for distance tests (CHDs) and the 6-m timed-hop test (6 m THT). Furthermore, the agility performance of the morning running group was significantly better than that of the evening and control groups.Conclusion Consequently, morning running interventions had a positive impact on key physical fitness parameters, including respiratory muscle strength, respiratory function, agility, and lower extremity strength in child footballers.

The devastating 6 February 2023 Kahramanmara & scedil;earthquake sequence in southeastern T & uuml;rkiye started with a moment magnitude (Mw) 7.8 earthquake, for which the initial rupture broke the Sak4ag & ouml;z segment near Nurda & gbreve;& imath; and then jumped into a bilateral rupture along multiple segments of the Eastern Anatolian fault zone (EAFZ). This complicated rupture was followed nine hours later by an Mw 7.6 event near Ekin & ouml;z & uuml;. To better understand the spatiotemporal evolution of aftershocks, site amplification, and the structural and tectonic framework of the EAFZ in this diffuse triple junction, we deployed a dense seismometer array covering both aftershock zones for nearly four months. The main Eastern Anatolian Seismic Temporary (EAST) array includes 125 nodal, 10 broadband, and 6 strong-motion seismic stations distributed around the rupture zone. An additional linear array of 73 nodal stations was also installed across the Pazarc & imath;k segment of the EAFZ and the Sak4ag & ouml;z segment near the Mw 7.8 epicenter to record fault-zone waves for similar to 30 days. This article shows example recordings and the EAST array geometry, preliminary research results, and the metadata related to all of the stations in this array. A deep-learning-based phase picking for one month of continuous recording yielded millions of seismic phase readings and tens of thousands of aftershock locations after phase associations. We also give examples of both local and teleseismic waveforms recorded by the nodal arrays, which can be used for subsequent high-resolution earthquake relocation, imaging of crustal structures, and fault-zone imaging.

Background/Objectives: Radiotherapy (RT) induces oxidative stress and structural damage in solid tissues, including the liver. This study aimed to investigate the histological and immunohistochemical effects of dexmedetomidine (DEX) and amifostine on their potential protective and regenerative properties against liver injury induced by radiation therapy. Methods: This study consisted of five randomized groups: control, RT, RT-D100, RT-D200, and RT-A (Amifostine). A total of 100 mu g/kg DEX, 200 mu g/kg DEX, and 200 mu g/kg amifostine were administered before radiotherapy as per the experimental design. After RT, liver specimens were analyzed for histological alterations, including periportal and perisinusoidal fibrosis, vacuolization, and pyknotic nuclei. Furthermore, immunohistochemistry investigations were conducted to evaluate apoptosis, mitosis, oxidative stress, and neural regeneration in non-neuronal liver tissue following radiotherapy and subsequent treatment. Results: The control group's liver tissue exhibited standard histological architecture, whereas the RT group displayed severe cellular degeneration, periportal and perisinusoidal fibrosis, cytoplasmic vacuolization, and an increase in pyknotic nuclei. The apoptotic index was markedly reduced in the RT-D100 and RT-D200 groups relative to the RT group. Furthermore, caspase-3 immunoactivity was negligible in the control group, while a significant increase was observed in the RT group. The administration of amifostine significantly increased GAP-43 levels. Conclusions: DEX mitigates RT-induced hepatic injury chiefly through antioxidant and anti-apoptotic pathways, whereas amifostine promotes hepatic regeneration by modulating GAP-43.

Background and Objectives: Post-menopausal estrogen decline is considered a contributing factor to sarcopenia, and inspiratory muscle training (IMT) may provide benefits in this demographic. This study examined the impact of a four-week IMT program on diaphragm thickness, abdominal wall muscle thickness (AWMT; transversus abdominis, internal oblique, and external oblique), and liver fat percentage in healthy elderly women. Materials and Methods: Twenty-six women aged 60-80 years were randomly assigned to an IMT group (n = 13) or a control group (n = 13). The IMT group used the PowerBreathe (R) Classic device at 40% of maximal inspiratory pressure (MIP), with weekly increments of 10%. Training was performed twice daily, five days per week, with 30 breathing cycles per session (60 per day). The control group maintained their usual routines. AWMT, diaphragm thickness (DT), and fatty liver density (FLD) were measured by a radiologist before and after the intervention. Results: After four weeks, the IMT group showed significant improvements in all parameters compared to controls. Mid-diaphragm thickness (MDT) increased by 11.44% (effect size (ES) = 0.358, p < 0.001) versus 0.76% in controls (p = 0.271). Posterior diaphragm thickness (PDT) improved by 7.48% (ES = 0.282, p < 0.001) versus 0.38% (p = 0.564). Right AWMT increased by 12.7% (ES = 0.492, p < 0.001) compared to 0.10% (p = 0.872), and left AWMT increased by 9.93% (ES = 0.395, p < 0.001) versus 2.64% (p = 0.014). FLD improved by 11.79% (ES = 0.959, p < 0.001) in the IMT group, while the control group showed no meaningful change (-0.13%, p = 0.847). Conclusions: A short-term IMT protocol significantly enhanced diaphragm and AWMT and reduced liver fat in elderly women. These findings support the use of IMT as a simple, non-invasive intervention to preserve musculoskeletal and metabolic health in aging populations.

Background: The extant research on Taekwondo has focused primarily on the physiological effects of training, with limited interest in psychological resilience, self-defence and quality of life levels. The present study examined the effects of Taekwondo exercises on psychological resilience, self-defence and quality of life levels in healthy female subjects. Methods: The present study comprised 30 healthy, sedentary female subjects. The subjects were randomly divided into two groups: one group participated in Taekwondo training (TG), while the other group served as the control group (CG). The sample sizes for both the TG and CG groups were 15. The TT group underwent conventional Taekwondo instruction, while the CG group maintained their habitual routine and refrained from sporting pursuits. The Brief Psychological Resilience Scale, the Physical Self-Defence Scale for Women, and the SF-12 Quality of Life Scale were administered before and after the six-week training period. Results: The 6-week Taekwondo training programme led to significant improvements in both physical health (PH) (p = 0.049) and mental health (MH) (p < 0.01) scores in female participants. It did not produce a significant change in psychological resilience (PR) scores (p > 0.05). It produced significant improvements in self-defence against simple physical attacks (SP) (p = 0.004) and self-defence against dangerous physical attacks (DP) (p = 0.041) scores. Conclusion: The positive effects of Taekwondo training on psychological resilience, physical self-defence and quality of life levels have been demonstrated in healthy female subjects. This study provides valuable insights into the impact of Taekwondo exercises on psychological resilience, physical self-defence and quality of life levels. The findings of this study can guide future intervention and programme design in the context of sports psychology.

Background: The impact of resistance training extends beyond the enhancement of muscle strength, encompassing improvements in physical performance, postural stability, and overall functional capacity. This study aimed to investigate the effects of a 4-week resistance training program on functional capacity, respiratory muscle strength, diaphragm thickness, and liver density in healthy older women. Methods: The study included 30 healthy women aged 60-80 years and was designed as a randomized controlled experimental trial. Participants were randomly assigned to a resistance training (RT) group or a control (CON) group. Each participant attended the laboratory on three occasions: during the initial visit, the study procedures were explained; the second visit involved baseline assessments (6MWT, diaphragm thickness and liver fat via ultrasound, and respiratory muscle strength); and final measurements were conducted after the 4-week training programme during the third visit. Results: When pre- and post-training measurements were compared, the resistance training (RT) group demonstrated a significantly greater improvement (8.02%) in the Six-Minute Walk Test (6MWT) distance compared to the control group (p < 0.001). In terms of diaphragm thickness (DT), the RT group showed a 16.66% increase, whereas the control group exhibited a 1.13% decrease (p < 0.001). Maximal inspiratory pressure (MIP) increased by 12.30% in the RT group, while it decreased by 7.25% in the control group, indicating a 19.55% greater improvement in the RT group (p < 0.001). Regarding maximal expiratory pressure (MEP), a significant improvement of 21.48% was observed in the RT group, whereas a 0.75% decrease was recorded in the control group, resulting in a 22.23% greater enhancement in the RT group (p < 0.001). Finally, liver density (LD) increased by 12.30% in the RT group, while it decreased by 7.25% in the control group (p < 0.001). Conclusion: As a result of resistance training, greater improvement was observed in functional capacity, respiratory muscle strength, diaphragm thickness and liver density in the training group compared to the control group.

The nutritional properties of five different green macroalgae including Ulva rigida, Chaetomorpha linum, Codium fragile, Caulerpa prolifera and Caulerpa racemosa f. requienii from Turkey were investigated. The chemical composition of green macroalgae was varied, with ash, crude fiber, protein, lipid and carbohydrate ranging from 40.71 to 52.82%, 12.02-17.56%, 4.40-26.19%, 0.57-3.85% and 4.58-42.28% in dry weight, respectively. The fatty acid contents of the algae were quite variable and palmitic acid (C16) was found to be the primary fatty acid for all the samples with a value of more than 49.61%. Palmitic acid was followed by oleic acid, which is a monounsaturated fatty acid. This study revealed that green algae are rich in important soluble carbohydrates such as myo-inositol and glucose, health promoting unsaturated fatty acids (mainly oleic acid) and essential macroelements such as potassium, magnesium and microelements such as iron, zinc and selenium. The results of the current study contribute to a better understanding of macroalgae and encourage their use in food-related applications.

Background It has been shown that neopterin levels in various body fluids can help predict the diagnosis of different malignancies. Although many studies have investigated the roles of serum neopterin concentrations, tryptophan metabolism, and the dietary inflammation index (DII) in various cancers, the connection between these factors and prostate cancer (PC) remains uncertain. The aim of this study was to investigate the predictive and prognostic roles of serum neopterin, and kynurenine levels, along with the kynurenine-to-tryptophan ratio (KTR) and DII in prostate cancer. Methods This study was conducted with 57 newly diagnosed prostate cancer patients, 55 benign prostate hyperplasia patients, and 56 healthy male individuals in the control group, all aged 40 years and older. Participants had specific anthropometric measurements taken, and three-day food records were kept. DII was calculated based on data for thirty-four available nutrients by using food records. Serum levels of neopterin, kynurenine, tryptophan, tumor necrosis factor alpha (TNF-alpha), and interferon-gamma (IFN-gamma) were measured using an enzyme-linked immunosorbent assay (ELISA) method. Results Serum neopterin (11.79 +/- 6.09), kynurenine (1655.48 +/- 1122.04), TNF-alpha (221.59 +/- 232.06) and IFN-gamma (137.68 +/- 107.11) levels were higher in the malignant group than in both the control (2.72 +/- 0.76, 352.40 +/- 69.33, 223.94 +/- 226.67, and 23.03 +/- 7.28, respectively) and benign groups (3.17 +/- 0.74, 377.94 +/- 109.05, 179.61 +/- 224.36, and 25.63 +/- 7.50, respectively) (p < 0.05). Another result of our study is that in the malignant group, serum neopterin levels exhibited significant positive correlations with serum kynurenine (r = 0.80, p < 0.0001), IFN-gamma (r = 0.86, p < 0.0001) and TNF-alpha levels (r = -0.27, p = 0.0453) and DII (r = 0.30, p = 0.0229), while they exhibited weak correlations with serum PSA, and other diet parameters. Additionally, kynurenine was the only parameter showing significant differences in mean values concerning surgical margins (p < 0.05). Conclusions The findings of this study support the hypothesis that serum neopterin and specific tryptophan catabolites (e.g., kynurenine), could serve as predictive and prognostic biomarkers for prostate cancer diagnosis. However, our results do not support the hypothesis that DII and certain dietary factors play a direct role in the development or diagnosis of prostate cancer.

The computational capacity envisaged for quantum computers poses a significant threat to today's traditional cryptographic algorithms. Although they are not yet large enough to compromise current cryptographic protocols, one can practice retrospective decryption since data packets traveling through the Internet can be easily sniffed. This threat extends to wireless communication security within consumer IoT devices that use lightweight cryptography due to limited computational power. Thus, countermeasures against potential quantum attacks should be preemptively adopted. NIST is leading efforts to standardize several algorithms as quantum-resistant Key Exchange Mechanisms (KEMs) and Digital Signatures. In this paper, we investigate the viability of these Post-Quantum algorithms in the Transport Layer Security (TLS) of power-constrained IoT devices. Specifically, it focuses on two widely used IoT network protocol stacks, i.e., Bluetooth Low Energy (BLE) and Wi-Fi. To this end, we build a realistic IoT testbed running IP over BLE. Our evaluation considers the impact of several realistic factors for the first time, such as using a chain of certificates on the server side and incorporating certificate validation methods such as Online Certificate Status Protocol (OCSP) and Certificate Revocation Lists (CRL). We also evaluate the impact of mutual authentication between the server and the client. Utilizing the outcomes of this evaluation, we then propose a novel approach for IoT devices to dynamically choose the most efficient KEM algorithm for TLS based on the device's physical network interface. The performance results provide valuable insights with respect to the TLS latency and energy consumption of consumer IoT devices.

Background The existing research on Muay Thai sports has focused predominantly on the physiological effects of training, with limited attention devoted to the study of quality of life, love of life and self-control. The present study examined the effects of Muay Thai exercises on quality of life, love of life and self-control scores in healthy male subjects. Methods The present study comprised 50 healthy sedentary male subjects. The subjects were randomly divided into two groups: one group engaged in Muay Thai training (MTT), while the other group served as a control group (CON). The sample sizes for the MTT and CON groups were both 25. The MTT group participated in basic Muay Thai training, while the CON group continued their normal life regime. The SF-12 quality of life scale, love of life scale and multidimensional self-control scale were administered before and after the six-week training period. Results The study concluded that the six-week Muay Thai training program had a significant effect on quality of life levels, with 13.23% (p = 0.003) and 21.93% (p < 0.001) of participants demonstrating improvements in physical and mental scores, respectively. In terms of self-control levels, the program was found to have a significant effect on initiation and inhibition scores, with increases of 23.78% (p = 0.001) and 24.69% (p < 0.001), respectively. It was concluded that had a significant effect on the sub-dimensions of the Love of Life scale with increases of Positive Attitude Toward Life (PAWL) 18.63% (p < 0.001), Happy Results of the Love of Life (HRLL) 20.11% (p < 0.001) and Meaningfulness of Life (ML) 15.62% (p < 0.001), respectively. However, no significant differences were detected in any of the scales within the control group. Conclusion Muay Thai exercises had a positive effect on quality of life, love of life and self-control levels in healthy male subjects. By providing valuable insights into how Muay Thai exercise affects quality of life, love of life, and self-control, this research can guide future intervention and program design in the context of sport psychology.

Background/Objectives: Lifestyle-related diseases such as obesity, diabetes, hypertension, metabolic syndrome, non-alcoholic fatty liver disease (NAFLD), and osteoarthritis disproportionately affect women due to hormonal, metabolic, and socio-cultural factors. Emerging evidence suggests that combining structured exercise with nano-curcumin, a bioavailable phytochemical formulation with potent antioxidant and anti-inflammatory properties, may provide synergistic benefits. This scoping review systematically synthesizes available evidence on the combined effects of nano-curcumin supplementation and exercise interventions on health outcomes in women with lifestyle-related diseases. Methods: Following the Joanna Briggs Institute methodology and the PRISMA-ScR framework, a comprehensive database search was conducted in March 2025 and updated in June 2025. Records were retrieved from Scopus (n = 30), Web of Science (n = 22), PubMed (n = 18), and other sources (n = 71), yielding a total of 141 studies. After screening and deduplication, eight studies met the inclusion criteria and were included in this review. All the studies were conducted in Iran with small sample sizes (12-53 participants) and short intervention durations (6-16 weeks). Therefore, the current evidence is geographically and demographically limited. Results: Across the included trials, the combined interventions produced additive or synergistic improvements in oxidative stress markers, inflammatory cytokines, lipid and glucose metabolism, cardiovascular function, pulmonary capacity, muscle fitness, and psychological outcomes (e.g., depression). When paired with nano-curcumin supplementation at different concentrations, high-intensity interval training, aerobic exercise, Pilates, and resistance training consistently outperformed exercise or supplementation alone in modulating antioxidant defenses, reducing systemic inflammation, and improving metabolic risk factors. Conclusions: The integration of exercise and nano-curcumin supplementation appears to confer superior benefits for women with lifestyle-related diseases compared with either approach alone. These findings highlight the potential of combining phytochemicals with lifestyle interventions to optimize women's health outcomes. However, most available evidence originates from small, short-term studies in single geographic regions. Large-scale, multicenter, randomized controlled trials with diverse populations are warranted to establish standardized protocols and optimal dosing strategies, and to assess long-term safety and efficacy.

The chromitites of the K & imath;z & imath;lda & gbreve; ophiolite (KO) are primarily characterized by massive and disseminated textures within refractory mantle peridotites, predominantly harzburgite and dunite, with occasional occurrences of banded and nodular chromitites. Based on chromite composition, these chromitites can be classified into two groups exhibiting a broad compositional range: intermediate (0.55 <= Cr# < 0.70, TiO2 = 0.08-0.51 wt%) and high-Cr (0.70 <= Cr# <= 0.77, TiO2 = 0.05-0.28 wt%). The compositions of minor and trace elements align consistently with variations in Cr#. Total PGE (Os, Ir, Ru, Rh, Pt, Pd) contents in these chromitites are generally less than 500 ppb, with many samples showing enrichment of IPGE (Os, Ir, Ru) relative to PPGE (Rh, Pt, Pd). However, certain samples from both groups display elevated PGE concentrations (Sigma PGE(intermediate) = 718 ppb, Sigma PGE(High-Cr) = 866 ppb) compared to other samples. The dominant platinum group mineral inclusions in chromite are Ru-rich laurite [(Ru, Os)S-2], with a single osmiridium (Os-Ir alloy) grain also observed suggesting formation under high-temperature and low & fnof;S-2 conditions. Primary base metal mineral inclusions include millerite and pentlandite. Additionally, some chromite crystals contain single or multi-phase silicate inclusions, such as clinopyroxene, orthopyroxene, olivine, and amphibole. Parental melt compositions, calculated from Al2O3 and TiO2 contents of chromites, indicate that most high-Cr chromitites originated from boninitic melts, whereas intermediate chromitites and some high-Cr samples derived from melts with intermediate compositions. Trace element compositions of amphibole and clinopyroxene inclusions in the chromite crystals from the intermediate group further support crystallization from hydrous intermediate melts. It is proposed that the intermediate chromitite group formed from partial melts influenced by fluids from the subducted oceanic crust during the early stages of subduction initiation, while high-Cr chromitites originated from hydrous melts derived from a more depleted mantle wedge in later stages.
