Exploring the Nexus Between Physical and Mental Health: Assessing Stress Through Heart Rate Variability
Authors: De La Torre - García Ana , Martínez - Iranzo Úrsula , Prats Boluda Gema , Ángel Serrano Rosa Miguel , Luis Martínez De Juan José , Herrera  Ligero Cristina
Published: February 2025

Physiological signals such as electrocardiography (ECG) have traditionally been associated with assessments of physical health. Mental health, meanwhile, often relies on subjective measures like self-report questionnaires and clinical interviews. Yet, the autonomic nervous system and the central nervous system are intrinsically linked to mental states like stress. While previous studies have associated certain parameters with stress, variability in findings and protocols, as well as limited exploration of some parameters, especially non-linear measures, highlight the need for further research.This paper examines how parameters extracted from ECG can be used to study acute stress levels. By analysing ECG data, we seek to identify patterns and correlations that reflect stress responses in individuals, potentially serving as reliable, objective markers.We conducted experiments exposing participants to controlled stress stimuli. Each session included a baseline measurement at rest, exposure to a stressor (the cold-pressor test), and a recovery phase. Continuous ECG recordingwere obtained, and a comprehensive range of Heart Rate Variability (HRV) parameters, encompassing time-domain, frequency-domain, geometrical and non-linear measures, was extracted to assess autonomic balance.Preliminary results demonstrate that certain HRV parameters change characteristically during acute stress exposure, indicating increased sympathetic activity (e.g., reduced mean and median NN intervals reflecting a shift toward higher heart rate). These physiological changes tended to normalise during recovery, underscoring the dynamic nature of the acute stress response. However, elevated parasympathetic-like measures (e.g., elevated sdnn, rmssd and pnni_50) during stress suggest that conscious or subconscious respiratory modulation can influence HRV indices. Moreover, some parameters revealed age-related differences that highlight how autonomic adaptability may diminish as individuals advance in age.These findings suggest that ECG-derived HRV parameters can serve as reliable, objective markers of acute stress. Understanding the physiological foundations of stress and the factors that modulate it, such as breathing patterns and age, may inform the development of non-invasive monitoring tools and interventions. This, in turn, could lead to more comprehensive evaluations of stress-related conditions like anxiety or depression, and support personalised strategies to enhance mental health and wellbeing.

Published: February 2025

Remote photoplethysmography (rPPG) emerges as a non-invasive alternative for pulse and pulse rate variability (PRV) measurement, eliminating the need for direct skin contact. This approach is particularly suitable for applications where wearable sensors are impractical, such as the automotive sector, where accurate and robust PRV monitoring is essential to enhance driver safety by providing real-time insights. This study evaluates the accuracy and robustness of rPPG signal extraction using the Freyja/IBV-Dataset, which comprises 73 participants with diverse intrinsic factors, such as age, body mass index (BMI), and skin phototypes, as well as extrinsic conditions, including varying lighting and distances. Seven rPPG algorithms (GREEN, POS, CHROM, ICA, FastICA, PVB, and LGI), selected for their established efficacy in handling environmental variations, were compared against electrocardiogram (ECG) as the reference standard. The findings reveal that the mean normal-to-normal interval (meanNNI) demonstrates the greatest robustness when estimated using ICA and FastICA, which achieved consistently low mean absolute errors (MAE) even under challenging conditions such as reduced lighting and increased distance. However, the estimation of the standard deviation of normal-to-normal intervals (SDNN), a parameter sensitive to noise and environmental conditions, showed higher errors. These discrepancies are attributed to intrinsic differences between mechanical (rPPG) and electrical (ECG) signals, disparities in sampling frequencies between devices, and environmental influences. This study highlights the need to optimize rPPG signal extraction and processing techniques to improve the accuracy and robustness of PRV parameter estimation. Future research should focus on increasing the image sampling rate, exploring PPG measurements closer to the face, and employing advanced artificial intelligence (AI) methods to adapt algorithms for challenging conditions, such as diverse skin phototypes and complex environmental settings.

Helicobacter pylori (H. pylori) infection can lead to peptic ulcers, chronic gastritis, lymphoma and gastric cancer. This study aimed to assess the factors related to H. pylori resistance after eradication and its recurrence after 6 months. 574 patients tested for H. pylori and those who positive has been assessed for recurrence after 6 months or resistance to treatment and factors related to recurrence in correlation with demographic data. 51% of men and 49% of women were still testing positive for H. pylori after receiving treatment.   The majority of patients who tested positive again for H. pylori were taking clarithromycin-based triple therapy, with only a small percentage being treated with levofloxacin, rate of resistance and recurrence were 23.54% and 8.7%, respectively. Most common symptoms after recurrence were epigastric pain and nausea (62.96%) and dyspepsia (55.55%). The highest rate of recurrence is related to O+ blood group, which is 47.82%. Recurrence rate after H. pylori eradication by standard therapy (clarithromycin triple treatment) or levofloxacin-based therapy is 8.7%. Poor sanitation, low income, and treatments regimens are independent risk factors for recurrence of H. pylori. Reducing the frequency of eating outdoors and treating family members may reduce H. pylori infection recurrence.

Authors: Magdalene Tyona Ngodoo
Published: February 2025

Onychomycosis is a fungal infection of the nails, characterized by thickening, discoloration, and brittleness. It is caused by dermatophytes, non-dermatophyte molds, and yeasts and poses a significant public health challenge, particularly in tropical regions like Nigeria. Current antifungal treatments often show inconsistent efficacy, prompting the search for alternative therapies. This study explores the potential of Cymbopogon citratus (lemongrass) extracts as antifungal agents targeting key enzymes involved in fungal pathogenesis in onychomycosis in Benue State, Nigeria. Using ethical approval and rigorous laboratory protocols, fungal samples were cultured, and the Squalene Epoxidase (SQLE) gene was identified. Phytoconstituents in C. citratus extracts were analyzed via Gas Chromatography-Mass Spectrometry. Molecular docking using the Schrodinger Glide protocol predicted interactions with SQLE, a critical enzyme for fungal ergosterol biosynthesis. Dodecanoic acid-1,2,3-propane showed the highest docking score (-65.13 kcal/mol) and a molecular weight of 638 g/mol, outperforming terbinafine (-64.39 kcal/mol, 327.9 g/mol). The compounds exhibited strong binding to SQLE, suggesting a mechanism for disrupting fungal membrane synthesis. These findings emphasize the integration of computational predictions with in vitro studies in developing effective treatments for onychomycosis, addressing a significant medical need locally and globally.

Published: February 2025

Asiaticoside, a bioactive compound derived from Glycyrrhiza glabra (licorice root), has garnered attention for its potential as a hypolipemic agent. This study explores the lipid-lowering effects of asiaticoside, focusing on its mechanism of action and pharmacological properties. In silico analysis showed a high activation probability (pa=0.934) for asiaticoside, indicating its strong potential to interact with targets involved in lipid metabolism, such as PPAR-α, and reduce blood lipid levels. Additionally, its low inhibition probability (pi=0.003) suggests minimal risk for non-specific biological interference, making it a promising candidate for therapeutic use with a favorable safety profile. Asiaticoside’s antioxidant and anti-inflammatory properties further enhance its potential for cardiovascular protection by reducing oxidative stress, a key factor in atherosclerosis. While preliminary in silico results are promising, further in vitro and in vivo studies are required to confirm its efficacy, safety, and pharmacokinetics. Overall, asiaticoside represents a promising natural agent for managing hyperlipidemia and related metabolic disorders, offering an alternative to conventional synthetic therapies.

Abstract
This study focuses on the importance of implementing Javanese Krama in character building for students at MI 'Ulumiyah Pare, with a focus on teaching the values ​​of politeness, ethics, and etiquette. The method used is a descriptive qualitative approach, involving in-depth interviews with teachers and students, as well as observations to identify the practice of using Javanese Krama in schools. The collection data were analyzed descriptively to understand the patterns in the application of this language in shaping students' characters.
This study aimed to analyze the role of Javanese Krama in shaping students' characters, as well as to identify challenges and supporting factors in its implementation. The findings show that the use of this language has a strong foundation in various educational theories, including Vygotsky's socio-cultural theory, which emphasizes the importance of social interaction in learning, and Thomas Lickona's character education theory, which integrates knowledge, feelings, and moral actions. Through the practice of Javanese Krama, the students can develop an attitude of respect and ethical awareness, which are internalized through daily conversation and social interaction.
However, this study also found challenges in its implementation, such as the complexity of vocabulary that makes 40% of students experience difficulties, as well as the influence of the modern environment that causes a decrease in the use of the language at home. Teachers act as facilitators who encourage this practice with positive reinforcement, which is in line with Skinner's behaviorism theory. Support from family and community is also very important, as highlighted in Berry's acculturation theory and Bandura's social learning theory, to ensure the sustainability of the use of Krama Javanese. This study underscores the importance of a collaborative approach between schools, families, and communities in supporting sustainable character education through language.

The purpose of the research is to evaluate the possibility of using the gene pool of the Mandolong breed to improve the productive qualities of Kalmyk cattle. The research was carried out at the livestock complex
«IЕ Bugaev V. S.» of the Samara region, where beef cattle of Kalmyk and Mandolong breeds are bred. To conduct the experiment, four groups were formed from newborn bulls: I (control) – Kalmyk breed, II (control) – Mandolong breed, III (experimental) – first–generation crossbreeds (F1) ½K×½M, IV (experimental) – second-generation cross-breeds (F2) ¼K×¾M. Bulls were raised according to the technology adopted in beef cattle breeding. It was found that crossbred bulls did not exceed the purebred Mandolong breed in live weight, but at the same time they were larger than their peers of the Kalmyk breed at all age periods. At the age of 18 months, the live weight was higher in com-parison with the Kalmyk breed in group II bulls – by 184.1 kg (37.7%), group III – by 91.5 kg (18.7%), group IV –
by 124.1 kg (25.4%). The difference in slaughter yield between the experimental bulls was, respectively, 3.19% (P<0.001); 0.93% (P<0.001); 1.72% (P<0.001). As a result of crossing, the muscularity of the hip part of the trunk significantly improved in crossbreeds, the hip completion coefficient increased in F1 crossbreeds by 13.62 (10.7%), in F2 crossbreeds by 18.49 (14.5%), the fullness coefficient, respectively, by 13.10 (10.7%) and 18.01 (14.7%). The study of the morphological composition of the left half-carcasses showed that the meat index, characterizing the yield of pulp per 1 kg of bones, increased in comparison with the Kalmyk breed in crossbreeds F1 – by 0.20 kg (4.4%),
F2 – by 0.21 kg (4.7%).

When the grain content is 3, 6 and 10 % of grains damaged by wheat thrips larvae, in winter wheat varieties Povolzhskaya 86, Povolzhskaya Niva and spring wheat Kinelskaya 59 and Kinelskaya Yubileinyaya, the grain quality corresponds to class II strong. However, when the grain of winter wheat of the Konstantinovskaya variety contains more than 3 % (in experiments
6 and 10 %), spring wheat variety Kinelskaya Otrada more than 6 % (in experiments 10 %) of grains damaged by wheat thrips, grain quality corresponds to valuable class III, which makes it necessary to determine the degree of damage to wheat grain by wheat thrips after harvesting.

Proper fruit harvesting timing is crucial in agriculture to ensure optimal product quality. Particularly, manually determining fruit ripeness requires significant time and expertise from farmers. Inaccuracies in harvest timing often lead to resource wastage and lower crop quality. Simultaneously, advancements in image-based classification technology offer promising solutions to address these challenges. Convolutional Neural Networks (CNN) are powerful deep learning architectures effective in recognizing complex patterns in image data, enabling high-accuracy visual information processing. YOLOv8 (You Only Look Once version 8) represents a recent implementation of object detection algorithms renowned for its ability to swiftly and accurately detect objects in real-time. Many studies have used limited data under controlled conditions. Additionally, there is a lack of research exploring how YOLOv8 and CNN models can be adapted to various environmental conditions, such as natural lighting and diverse backgrounds. This study proposes the integration of CNN with YOLOv8 to autonomously classify fruit ripeness stages, specifically focusing on pineapples. This method facilitates automated detection and classification of fruit ripeness, thereby enhancing harvest management efficiency for farmers. Performance testing of the YOLOv8 system yielded promising results with a mean Average Precision (mAP) of 88.5%, Precision of 78.4%, and Recall of 84.2%. These findings affirm the system’s capability to consistently and accurately assess pineapple ripeness across various field conditions. By harnessing CNN and YOLOv8 technologies, we introduce an innovative approach to fruit harvesting management applicable in modern agricultural practices.

COVID-19 syringes plastic waste is difficult to recycle, so this study focuses on the use of this waste in manufacturing reinforcing bars as an alternative to steel reinforcing bars or carbon fiber reinforced polymer bars. After sterilizing COVID-19 syringes, these syringes are immersed in liquid nitrogen and then hammered to turn into random fibers. After spinning these fibers to the appropriate diameter, they are coated with a layer of epoxy to become reinforcing bars. To test the efficiency of these bars, six samples of concrete beams were cast. The first beam sample was reinforced with manufactured plastic bars made from COVID-19 syringes. The second and third beam samples were reinforced with deformed and plain steel reinforcing bars, respectively. The fourth beam sample was reinforced with carbon fiber reinforced polymer bars. Meanwhile, the fifth and sixth beam samples were reinforced with glass fiber reinforced polymer bars and basalt fiber reinforced polymer bars, respectively. The experimental results showed a 29.5%, 18.2%, and 6.8% increase in the ultimate load of the beam sample reinforced with the manufactured plastic bars compared to the beam sample reinforced with plain steel reinforcing bars, the beam sample reinforced with basalt fiber reinforced polymer bars, and the beam sample reinforced with glass fiber reinforced polymer bars, respectively.

A evolução da marca Barbie: representações culturais, impacto no consumo e transformações na publicidade
Authors: Pinheiro Weider Silva , Valente Evelyn Aida Tonioli
Published: February 2025

A marca Barbie tem desempenhado um papel central na cultura popular desde sua criação, refletindo e influenciando padrões de beleza, gênero e identidade. Este estudo tem como objetivo analisar a evolução da representatividade da Barbie ao longo das décadas, investigando seu impacto sociocultural e as estratégias de branding utilizadas para se adaptar às transformações históricas e sociais. A pesquisa foi realizada por meio de uma revisão integrativa da literatura, considerando estudos acadêmicos que discutem a relação entre a Barbie e as questões de diversidade, inclusão e empoderamento feminino. Foram analisados trabalhos que abordam a inserção da Barbie Negra no mercado, os discursos feministas incorporados em campanhas publicitárias e as estratégias mercadológicas utilizadas para manter a relevância da marca. Os resultados indicam que, apesar dos esforços da Mattel para diversificar sua linha de produtos e promover uma imagem mais inclusiva, a representatividade na marca ainda é limitada por padrões estéticos eurocêntricos e dinâmicas de consumo que perpetuam normas tradicionais de gênero. O estudo também aponta que, embora a Barbie tenha passado por mudanças significativas em sua representação, essas transformações estão frequentemente ligadas a estratégias comerciais, sem promover alterações estruturais profundas nos discursos de gênero e identidade. Conclui-se que, embora a Barbie tenha evoluído para refletir um mundo mais diverso e plural, sua relação com o consumismo e a publicidade limita seu potencial transformador. Assim, é necessário um olhar crítico sobre a representatividade na indústria de brinquedos, considerando não apenas a presença de diversidade, mas também suas reais implicações sociais.

O leite de búfala e seus derivados tem sido alvo de diversos estudos. As bactérias ácido láticas (BAL) fazem parte da microbiota lática e contribuem para o desenvolvimento de propriedades funcionais e sensoriais em muitos alimentos. Este trabalho objetivou realizar a caracterização do potencial tecnológico de BAL isoladas de leite de búfala produzido na Ilha do Marajó. No isolamento foram obtidos quarenta (40) isolados de BAL, e realizados testes de Coloração de Gram, Catalase, Atividade Proteolítica, Teste de Produção de Gás, Produção de Diacetil, Teste de Lactofermentação e Capacidade Acidificante. Os resultados fenotípicos e morfológicas mostraram que as BAL são gram-positivos, com 31 isolados apresentando a forma de cocos e 9 a forma de bacilos. No que se refere aos resultados da caracterização bioquímica, 34 isolados apresentaram-se como catalase negativos; 29 isolados caracterizando- se como homofermentativos e 11 como heterofermentativos; 17 isolados apresentaram atividade proteolítica; 9 isolados se mostraram produtores de diacetil; e 7 isolados apresentaram a formação do coágulo gelatinoso e uniforme, proveniente da fermentação lática. Para a atividade acidificante, todos os isolados foram considerados como uma cultura lática com rápida produção de ácido. Ao comparar todos os isolados estudados, pode-se dizer que os que apresentaram os melhores resultados foram: I32, I33, I35 E I40. Pesquisas sobre a identificação e caracterização de BAL do leite de búfala são de grande importância, pois auxilia na produção de fermentos láticos a partir de leite de búfala, e contribui para a melhoria da qualidade de derivados.
