Expression of Immune Genes and Leukocyte Population in the Conjunctiva, Harderian Gland and Trachea of Chickens Inoculated with a Live Vaccine and a Field Strain Infectious Laryngotracheitis Virus
Authors: Tran Thanh Tien , Andronicos Nicholas , Gerber Priscilla F.
Published: November 2024

Changes in leukocyte populations and immune gene expression associated with attenuated vaccine (SA2) or field (Class 9) strains of infectious laryngotracheitis virus in chicken pullets were observed primarily in the trachea and conjunctiva, while no substantial changes were detected in the Harderian gland. Although there were no significant differences in cellular infiltration in the tissues exposed to Class 9 and SA2, Class 9 induced greater changes in immune gene expression than SA2 in the trachea and conjunctiva and significantly upregulated CD4, CD8A, IRF1, STAT4 and downregulated CXCL12 expression in the trachea. Meanwhile, SA2 significantly upregulated CD14 and downregulated MPO, CCR6 and RAG1 expression in the conjunctiva. In conclusion, gene expression in pullets infected with SA2 and Class 9 were mostly related to inflammatory and tissue-repairing responses in the trachea and conjunctiva. Compared to SA2, Class 9 inoculation was associated with a more robust gene expression of immune markers; however, a larger infiltration of Kul01+, Bu1+ and CD8a+ cells was observed in trachea and conjunctiva after SA2 inoculation.
Degree of Unitary Self-Representation on the Rorschach (SRI): Diagnostic and Psychotherapeutic Value in Psychosis Clinics
Authors: Prudent Cécile
Published: November 2024

The aim of this article is to present a new marker of the degree of self-representation unity, developed from the Rorschach test, to assess the strength or fragility of psychotic patients’ narcissistic foundations. The marker exhibited discriminative value when comparing a group of paranoid subjects (n = 25) to two other groups of schizophrenic (n = 26) and paranoid schizophrenic subjects (n = 30). This indicator also appears useful for assessing the positive effects on the narcissistic Ego in psychotherapy.
Monitoring Age-Related Changes in Gait Complexity in the Wild with a Smartphone Accelerometer System
Authors: Di Bacco Vincenzo E. , Gage William H.
Published: November 2024

Stride-to-stride fluctuations during walking reflect age-related changes in gait adaptability and are estimated with nonlinear measures that confine data collection to controlled settings. Smartphones, with their embedded accelerometers, may provide accessible gait analysis throughout the day. This study investigated age-related differences in linear and nonlinear gait measures estimated from a smartphone accelerometer (SPAcc) in an unconstrained, free-living environment. Thirteen young adults (YA) and 11 older adults (OA) walked within a shopping mall with a SPAcc placed in their front right pants pocket. The inter-stride interval, calculated as the time difference between ipsilateral heel contacts, was used for dependent measures calculations. One-way repeated-measures analysis of variance revealed significant (p < 0.05) age-related differences (mean: YA, OA) for stride-time standard deviation (0.04 s, 0.05 s) and coefficient of variation (3.47%, 4.16%), sample entropy (SaEn) scale 1 (1.70, 1.86) and scale 3 (2.12, 1.80), and statistical persistence decay (31 strides, 23 strides). The fractal scaling index was not different between groups (0.93, 0.95), but exceeded those typically found in controlled settings, suggesting an upregulation in adaptive behaviour likely to accommodate the increased challenge of free-living walking. These findings support the SPAcc as a viable telehealth instrument for remote monitoring of gait dynamics, with implications for unsupervised fall-risk assessment.
Investigation of Freeway Incident Duration Using Classification and Regression Trees Based on Multisource Data
Authors: Xie Xun , Li Gen , Wu Lan , Du Shuxin
Published: November 2024

Targeted contingency measures have proven highly effective at reducing the duration and harm caused by incidents. This study utilized the Classification and Regression Trees (CART) data mining technique to predict and quantify the duration of incidents. To achieve this, multisensor data collected from the Hangzhou freeway in China spanning from 2019 to 2021 was utilized to construct a regression tree with eight levels and 14 leaf nodes. By extracting 14 rules from the tree and establishing contingency measures based on these rules, accurate incident assessment and effective implementation of post-incident emergency plans were achieved. In addition, to more accurately apply the research findings to actual incidents, the CART method was compared with XGBoost, Random Forest (RF), and AFT (accelerated failure time) models. The results indicated that the prediction accuracy of the CART model is better than the other three models. Furthermore, the CART method has strong interpretability. Interactions between explanatory variables, up to seven, are captured in the CART method, rather than merely analyzing the effect of individual variables on the incident duration, aligning more closely with actual incidents. This study has important practical implications for advancing the engineering application of machine learning methods and the analysis of sensor data.
An Emotion Recognition Method for Humanoid Robot Body Movements Based on a PSO-BP-RMSProp Neural Network
Authors: Gao Wa , Jiang Tanfeng , Zhai Wanli , Zha Fusheng
Published: November 2024

This paper mainly explores the computational model that connects a robot’s emotional body movements with human emotion to propose an emotion recognition method for humanoid robot body movements. There is sparse research directly carried out from this perspective to recognize robot bodily expression. A robot’s body movements are designed by imitating human emotional body movements. Subjective questionnaires and statistical methods are used to analyze the characteristics of a user’s perceptions and select appropriate designs. An emotional body movement recognition model using a BP neural network (EBMR-BP model) is proposed, in which the selected robot’s body movements and corresponding emotions are used as inputs and outputs. The corresponding topological architecture, encoding rules, and training process are illustrated in detail. Then, the PSO method and the RMSProp algorithm are introduced to optimize the EBMR-BP method, and the PSO-BP-RMSProp model is developed. Through experiments and comparisons for emotion recognition of a robot’s body movements, the feasibility and effectiveness of the EBMR-BP model, with a recognition rate of 66.67%, and the PSO-BP-RMSProp model, with a recognition rate of 88.89%, are verified. This indicates that the proposed method can be used for emotion recognition of a robot’s body movements, and optimization can improve emotion recognition. The contributions are beneficial for emotional interaction design in HRI.

Published: November 2024

In response to the COVID-19 pandemic, higher education institutions adopted a set of measures to ensure safe face-to-face teaching and to control potential outbreaks. However, the effectiveness of the implemented measures is dependent on the behavior of students, who are generally young, often displaced, living with other colleagues, and constantly seeking physical contact, which makes their behavior outside the institution also of particular relevance to controlling the pandemic. An online questionnaire was developed and applied to characterize the behaviors adopted by students inside and outside the higher education institution, as well as risk perception based on the health belief model (HBM) and unrealistic optimism, with the participation of 620 students from three Portuguese higher education institutions. The adoption of safe behaviors is related to a greater perception of the benefits and of the severity of COVID-19. Unrealistic optimism also has a negative impact on preventive behaviors. The behaviors least adopted by students concerning potential exposure to COVID-19 were disinfecting hands and equipment after use, as well as physical distancing from colleagues. With regard to behaviors adopted outside the institution, it was found that students did not avoid physical contact with colleagues and family members. These findings contribute to our understanding of student behavior during the COVID-19 pandemic, help institutions understand if the applied strategies were effective or not, and denote the need to reinforce or improve the implemented strategies.
Effective Communication of System-Level Events for Hospital System Health and Nurse Well-Being: A Qualitative Study
Authors: Brittain Angela C. , Carrington Jane M.
Published: November 2024

Many injuries and deaths occur yearly in the United States due to preventable errors; however, documented harm is lower in hospitals with Magnet® designation from the American Nurses Credentialing Center (Silver Spring, MD, USA). This manuscript illustrates insights from Magnet® and non-Magnet® nurses and nursing leaders regarding what impacts hospital system health, how those factors are communicated, and how hospital system health impacts patient safety. A qualitative descriptive approach was used with semi-structured interview questions. Within-methods data triangulation was applied to transcribed interviews using thematic analysis, application of the Goodwin statistic, and natural language processing (NLP). Thematic analysis revealed the four main themes of Healthy Systems, Unhealthy Systems, Patient Safety, and Nurse Well-Being. NLP revealed non-Magnet® leaders and nurses scored highest for anxiety, anger, and sadness, in contrast to Magnet® participants who had the highest levels of positive emotion. Key findings from the Magnet® participants revealed that poaching employees and placing people in the wrong positions harm hospital system health and patient safety. The use of within-methods data triangulation illuminated the contextual depth of the participants’ speech, revealing the alarming emotional state that non-Magnet® nurses and leaders are facing. Healthcare staff’s wellness must be prioritized to cultivate environments that provide safe care.

Inappropriate antimicrobial use in food animal farming propels antimicrobial resistance (AMR) that affects all health domains. Colistin is a ‘Reserve’ antibiotic for human treatment to be conserved for multidrug-resistant pathogens; however, it is being used as an animal growth promoter in many developing countries. The evolution of mobilized colistin resistance (mcr) gene-mediated colistin resistance has been reported to be associated with rampant colistin use. This study investigated the current variants of the mcr gene in chicken gut contents in Bangladesh. A cross-sectional study was designed to assess the mcr-1 to mcr-5 genes in 80 fresh poultry droppings from commercial poultry farms and 40 poultry droppings from household farms. DNA was extracted from each poultry dropping using commercial kits (Qiagen GmbH, Hilden, Germany). Real-time quantitative polymerase chain reaction (RT-qPCR) was employed using the qTOWER3 thermal cycler (Analytik Jena GmbH, Jena, Germany) to analyze the mcr gene variants in the extracted DNA. This study observed that 47.5% (57/120) of the samples exhibited the presence of at least one mcr gene out of the five variants investigated. The individual detection rates of the mcr-1, mcr-2, mcr-3, mcr-4, and mcr-5 genes were 42.5% (51/120), 2.5% (3/120), 1.7% (2/120), 5% (6/120), and 9.2% (11/120), respectively. The co-carriage of two or more genes was found in over 10% (10/57) of the samples. The triple occurrence of mcr genes was identified in three samples with the combination of mcr-1+mcr-2+mcr-4, mcr-1+mcr-3+mcr-5, and mcr-1+mcr-4+mcr-5. Overall, a significantly higher number of mcr genes were identified in the commercial farm chicken droppings compared to the household chicken droppings (p = 0.007). The existence of mcr genes in poultry feces in Bangladesh emphasizes the importance of proper poultry waste disposal and good hygiene practices in poultry livestock and its value chain. The potential impact of environmental ARGs should be considered in national and global policy documents. An integrated and combined approach to the One Health concept should be applied in all domains to understand and control the environment’s role in the evolution and transmission of AMR.

Published: November 2024

Alfalfa, a crop cultivated worldwide for use as livestock feed, exhibits great adaptability to various environmental conditions. This study evaluates the biomass production, lipid peroxidation, photosynthetic pigments and osmo-compatible response in Medicago sativa var CW660 mycorrhizae (AM) and non-mycorrhizae (NM) plants with Rhizophagus intraradices and when subjected to salinity (100 mM and 200 mM of NaCl). They were evaluated using the following morphological parameters: foliage fresh weight (FFW), foliage dry weight (FDW), root fresh weight (RFW), root dry weight (RDW), foliage length (FL) and root length (RL), chlorophylls a and b, proline and malondialdehyde (MDA) in AM and NM plants treated with different concentration of NaCl. The LFW and the LDW were higher in M plants. The RFW and the RDW increased in control AM plants, and under different saline treatments there were no differences between AM and NM in either parameter. FL increased in the control and at 100 mM of NaCl in M plants. Chlorophyll a decreased 27–30% and b decreased 1–50% in AM and NM plants at 200 mM NaCl. The proline level increased four times and promoted a defense in AM plants at 200 mM of NaCl. Lipid peroxidation decreased in AM plants by 10% at maximum salinity. M. sativa CW660 is sensitive to salinity stress, and inoculation with arbuscular mycorrhizal fungi (AMF) regulates its physiology and performance under such conditions, with osmotic protection and membrane protection.
Exploring Asymmetric Gender-Based Satisfaction of Delivery Riders in Real-Time Crowdsourcing Logistics Platforms
Authors: Li Dan , Zhang Yi
Published: November 2024

This study investigates gender-based differences in the satisfaction ranking of riders on real-time crowdsourcing logistics platforms, using online reviews from the Ele.me platform. Quantitative methods, including the frequency ratio-based Analytic Hierarchy Process (AHP), probabilistic linguistic term sets (PLTS), and fuzzy comprehensive evaluation (FCE), were applied to analyze satisfaction differences between men and women riders. The findings reveal an asymmetric pattern in satisfaction preferences: women riders place more emphasis on perceived value, while men riders prioritize service perceived quality. Although both groups rank platform image, product perceived quality, and rider expectations similarly, the importance of these factors varies significantly, indicating an underlying asymmetry in their expectations and values. Women riders express higher satisfaction with platform image, rider expectations, service perceived quality, and product perceived quality, with rider expectations showing the largest difference. Additionally, the multi-criteria decision-making methods used in this study offer insights for optimizing service performance in real-time crowdsourcing logistics platforms, particularly in handling uncertainty and enhancing system adaptability through fuzzy sets. These findings provide a basis for developing gender-specific strategies aimed at enhancing rider satisfaction, minimizing turnover, and improving platform adaptability—contributing to a more inclusive and sustainable logistics supply chain.

Published: November 2024

In child and adolescent inpatient, residential and day-treatment facilities, the use of physical restraints and the occurrence of critical incidents are a significant problem. Restraints may sometimes be necessary if a child exhibits dangerous aggressive behavior, but may also be misused or overused, and have been shown to be preventable in many cases. This study aims to investigate if the implementation of the Neurosequential Model of Therapeutics (NMT) has an effect on the annual number of physical restraint incidents in a residential treatment facility for children with complex mental health disorders. Data before and after NMT implementation were collected from the agency’s restraint records. The results showed that post-NMT implementation, there was a substantial and sustained reduction in restraint incidents, with a Cohen’s d value of 2.03, indicating a very large effect. Limiting restraint use in treating children with complex mental health disorders can foster a safer and more therapeutic environment, with potential improvements in treatment outcomes. This study demonstrated a substantial drop in restraint incidents following the implementation of the Neurosequential Model in a residential facility for children aged 7–13. This reduction is presumably pivotal for children with complex mental health disorders, making treatment less coercive and offering promise for settings in which restraint incidents are a concern.
Adopción homoparental a la luz del interés superior del niño en Ecuador desde un enfoque constitucional
Authors: Morán Garcés Yeika Fabiola , Dueñas Cedeño Ana Elizabeth
Published: November 2024

En el presente artículo científico se realizó una investigación referente a la prohibición de la adopción homoparental expresada en el artículo 68 inciso segundo de la Constitución de la República del Ecuador 2008, cuyo propósito fue analizar desde la normativa constitucional como esta prohibición contradice otros derechos dando un enfoque al Interés Superior del menor en situación de adoptabilidad. Se aplicó el método cualitativo para la recopilación de información y el instrumento bibliográfico que constó principalmente de artículos de revistas, libros, jurisprudencia y normativa legal entre otros; además se utilizó el derecho comparado para realizar un breve contraste entre la legislación ecuatoriana y legislaciones de Argentina, Colombia y España. Se llegó a establecer como el Interés Superior del niño debe tomarse en cuenta en todas las decisiones que las autoridades o el estado mismo deben tomar en consideración a salvaguardar sus derechos al ser los niños un grupo vulnerable. Se concluyó, de esta manera, que la prohibición a las parejas del mismo sexo de participar en los procesos de adopción, más allá de contraponerse al principio de igualdad y no discriminación, es inconstitucional frente al interés superior del adoptado limitando sus derechos como el tener una familia, una identidad, etc.
Computational modeling of localized corrosion in steel pipelines supported by composite sleeves
Authors: Ahmed Benmansour Sid , Mohammed Benramdane , Abderrahim Benmoussat
Published: November 2024

Pitting corrosion is a worrying phenomenon in the oil industry representing a major threat that can lead to the reduction of the structural integrity of pipeline transportation networks. To prevent this corrosion risk, active cathodic protection with a potential maintained at – 850 mV Cu/CuSO4 is used as a coating protection system based on bituminous binders to isolate the steel from the corrosive soil environment in hydrocarbon transportation pipelines. In this work, we examine the clock spring repair method by applying composite paths including a numerical simulation on corroded tubes using ANSYS software. The approach involves analyzing the structure under three scenarios: without defects, after the introduction of elliptical simulated corrosion pits, and following repair with multilayer reinforcement using a composite sleeve. The results indicate that the stress distribution varies across each scenario. In the case of a structure with parabolic corrosion defects, the Von Mises stresses are unevenly distributed. The defect exhibits a peak stress that could lead to the propagation of corrosion pits, necessitating repair. Conversely, in the scenario where the corroded structure is reinforced with a composite sleeve, the maximum Von Mises stress is decreased to levels comparable to those of an uncorroded pipe, demonstrating the necessity and effectiveness of using composite sleeve reinforcement.

The Mythical and Symbolic Dynamics of Tattooing in Melanie Fazi's Serpentine
Authors: Maouchi Amel
Published: November 2024

This article offers a study of the mythical and symbolic dynamics of tattooing in Melanie Fazi's Serpentine, taking an approach based on the principles of mythocriticism. Far from being limited to an ornamental dimension, the tattoo in this novel becomes a central narrative medium, a vector of psychological and spiritual metamorphosis. By mobilizing the theories of Carl Jung on archetypes and Gilbert Durand on the symbolic imagination, the analysis reveals how magical inks – Mnemosyne, Somnifuge, Onirograph, Nocturne – update archetypal schemas, allowing the characters to transcribe their inner struggles in a cathartic approach. The body, thought of as a palimpsest, becomes the space for projecting unconscious anxieties and desires, thus articulating a dialectic between the visible and the invisible, the individual and the collective. The tattoo is then part of an initiatory logic, where the physical pain of the act represents a symbolic death and an identity rebirth. The article shows how Fazi redefines tattooing through a poetics of the body and myth, orchestrating a dialogue between ancestral motifs and contemporary issues of identity and memory. Serpentine thus presents itself as a complex reflection on transformation, rooted in a literary reinvention of universal archetypes.

Effect of alternate wetting and drying technique (AWD) on water productivity of paddy in major irrigation schemes – A case study in Mahaweli System B
Authors: Wijesundara Wijesundara Ranasingha Appuhamilage Tharaka Prabhath
Published: November 2024

This report investigates the effectiveness of the Alternate Wetting and Drying (AWD) technique on water productivity and yield in paddy cultivation within Mahaweli System B, located in Sri Lanka's dry zone. With increasing water scarcity, particularly during the Yala season, farmers struggle to meet irrigation demands using traditional methods. The study compares AWD with conventional irrigation practices, focusing on its ability to reduce water consumption while maintaining or increasing rice yields. Two paddy fields were selected for trials, and the results show that fields using AWD consumed significantly less water, averaging 3.7 feet per acre, compared to 5.3 feet in conventionally irrigated fields. Moreover, AWD fields produced an average yield of 6.04 tons per hectare, an increase of over 100 kg compared to the control fields, which yielded 5.04 tons per hectare. The technique also reduced the frequency of irrigation events, offering a practical solution to water management challenges in the region. These findings indicate that AWD can enhance water productivity without sacrificing crop yield, making it a promising strategy for areas facing water scarcity. However, further studies across multiple seasons and varied locations are recommended to validate its long-term benefits and adaptability.

Introdução: A injúria renal aguda (IRA) decorrente da sepse é frequente em Unidades de Terapia Intensiva (UTIs) e reversível dependendo do diagnóstico precoce e medidas terapêuticas efetivas. Objetivo: Caracterizar o perfil e indicações de hemodiálise em pacientes sépticos com IRA nas UTIs do Hospital da Santa Casa de Misericórdia de Vitória (HSCMV). Método: Trata-se de um estudo transversal, observacional, descritivo e quantitativo de pesquisa documental prospectivo. O estudo foi aprovado pelo Comitê de Ética em Pesquisa com seres humanos (CEP), com coleta de dados com duração de 12 meses pelo sistema MV. Foram incluídos pacientes adultos, sem ou com Doença Renal Crônica (DRC) prévia não dialítica, diagnosticados com sepse e IRA que evoluíram para hemodiálise acompanhados nas UTIs do HSCMV. Resultados: Dos 73 pacientes incluídos, a idade média foi 64 anos, 50,7% eram do sexo masculino, 80,8% eram pardos e 65,8% hipertensos. Entre eles, 76,7% foram classificados pelo KDIGO (Kidney Disease Improving Global Outcome) como estágio 3 de IRA e 63% iniciaram terapia de substituição renal devido à hipervolemia refratária. O desfecho do estudo revelou mortalidade de 80,8% dos pacientes internados em UTI em vigência de diálise com IRA associada à sepse. Conclusão: O perfil dos pacientes sépticos que evoluíram para IRA, reforça que idade avançada, comorbidades associadas, assim como estágio mais severo da classificação KDIGO, apresentam pior desfecho, com alta mortalidade. É necessário protocolos para manejo da IRA na sepse e treinamento das equipes multidisciplinares para mudança dessa realidade.

Published: November 2024

A gastrite é uma inflamação da mucosa gástrica que pode ser desencadeada por diversos fatores, tais como o uso prolongado de alguns medicamentos, o tabagismo, e a infecção pela bactéria Helicobacter pylori (HP). A prevalência dessa infecção engloba, aproximadamente, metade da população mundial, e, embora a relação dessa com a gastrite não se encontrar completamente elucidada, sabe-se que a virulência bacteriana, o sistema imunológico do hospedeiro e as influências ambientais interagem a constituir um mecanismo complexo que estabelece diferentes fenótipos da gastrite. Esses diferentes fenótipos podem distinguir-se em cronicidade, gravidade, diagnóstico tardio, resposta ou refratariedade ao tratamento, e complicações clínicas. Esta revisão de literatura visa explorar a fisiopatologia da gastrite associada a Helicobacter pylori e suas implicações clínicas, a fim de fornecer uma compreensão abrangente dessa condição e suas implicações para a prática médica, abordando sua associação com úlceras pépticas, câncer gástrico e anemia, além de revisar opções terapêuticas disponíveis contra esta infecção. Para tanto, foram identificados 154 artigos e, destes, foram selecionados 18 para este estudo com base nos critérios de inclusão e de exclusão adotados. Desse modo, observou-se a ação potencializadora da H. pylori no desenvolvimento de algumas doenças gastroenterológicas, como constatado no aumento da expressão genética de PREX2, encontrado em células cancerosas e nos achados endoscópicos de nodularidade antral, ambos em decorrência desta bactéria, o que permite concluir a estreita relação da gastrite com implicações clínicas de intensa gravidade e a longo prazo.

Inter-relação entre os estilos de aprendizagem de Kolb e a análise psicométrica de resiliência em docentes de medicina de Curitiba
Authors: Brack Dilan Johann , Garcia Sofia Schauffert Vendruscolo , Loesch Maíra de Mayo Oliveira Nogueira
Published: November 2024

Introdução: Os estilos de aprendizagem propostos por David Kolb categorizam em Divergentes, Convergentes, Assimiladores ou Acomodadores a forma através da qual indivíduos processam a transformação das experiências em conhecimento, cada qual com suas devidas características. A resiliência, por sua vez, é a capacidade para adaptar-se a situações adversas, sendo um influenciador do processo de aprendizagem. Para fins práticos, a escala de resiliência Connor-Davidson (CD-RISC) é aplicada para uma estratificação da percepção sobre a resiliência individual, permitindo a sua monitorização. Objetivo: Analisar a inter-relação dos estilos de aprendizagem de Kolb e do nível de resiliência de docentes da escola de medicina. Material e método: Foi adotado um desenho observacional transversal. Após aprovação pelo comitê de ética, aplicou-se o questionário CD-RISC e o teste de aprendizagem de Kolb, junto com variáveis socioeconômicas e demográficas. Os formulários foram distribuídos eletronicamente para professores de uma instituição de ensino médico, com consentimento informado e garantia de anonimato e confidencialidade. Posteriormente, os dados foram analisados estatisticamente de forma descritiva e inferencial. Resultados: Não houve associação entre características pessoais com o estilo de aprendizado, mas observou-se que maior tempo de formação se correlata a maiores níveis de resiliência. Verificamos uma associação significativa entre professores com perfil Assimilador a níveis autorrelatados de resiliência menores, em contrapartida, professores com perfil Acomodador foram associados a níveis ótimos de resiliência. Conclusão: Existe inter-relação entre o estilo de aprendizagem e o nível de resiliência de docentes., podendo servir como mecanismo de individualização na implementação de medidas de prevenção para afecções psicopedagógicas.

The Mounts of Tessala (western of Algeria) is a remarkable site of plants diversity, characterized by the presence of numerous aromatic and medicinal species used by the local population as therapeutic agents, the mastic tree (Pistacia lentiscus L.) is among the plants inhabiting this mountain; it is a perennial shrub belonging to the family Anacardiaceae.
The dosage of some polyphenols (total phenols, flavonoids) varied respectively between 21.20 - 98.23 mg gallic acid equivalents/g and 39.767 - 91.288 mg catechin equivalents/g. ANOVA revealed a significant variation in the mean concentrations according to the used extract.
Evaluation of the antioxidant power of aqueous extracts has revealed a remarkable biological effect. The high inhibition percentages (100%) were found in the decocted extract at 10 mg/mL, followed by the macerated extract at 10 mg/mL, and finally the infused extract with 82.99% at 20 mg/mL. The DPPH free radical scavenging test revealed that the antioxidant activity of aqueous extracts varied significantly according to extract type and its concentration. 
The results obtained not only confirm the richness of active principles in the studied plant but also its therapeutic effectiveness.

This study addresses the problem of microbiological contamination in fish sold in the region of Tipaza, where food safety is a growing concern. It aims to assess the contamination levels in three fish species: sardine, mackerel saurale, and bogue. To achieve this, samples were collected and analyzed for total aerobic mesophilic bacteria, thermotolerant coliforms, coagulase-positive Staphylococcus aureus, and Salmonella. The results revealed that all samples contained total aerobic mesophilic bacteria and thermotolerant coliforms within acceptable limits. However, high levels of coagulase-positive Staphylococcus aureus were detected in bogue and saurale samples, indicating unsatisfactory bacteriological quality, particularly in samples from the city of Tipaza. No Salmonella contamination was observed. These findings highlight significant hygiene issues during fish transport and sale, contributing to microbial contamination. The study concludes that improving handling practices is crucial to ensuring fish safety and reducing health risks to consumers.

El objetivo del trabajo fue evaluar los resultados de implementación del sistema HACCP en la ordeña del módulo de producción de leche de bovinos de doble propósito, con la finalidad de controlar la mastitis subclínica y con ello reducir el Conteo de Células Somáticas (CCS/mL). La mastitis es la inflamación de la glándula mamaria y es el principal problema en los sistemas de producción de doble propósito en hatos lecheros en el trópico y es producto de la interacción de varios factores: el animal, el medio ambiente y los microorganismos, por lo tanto, el manejo del ordeño es crucial para controlar la mastitis dentro del hato lechero, así como el contenido de células somáticas por mL (CCS/mL). Posterior a la implementación de sistema HACCP se midieron durante seis meses: mastitis subclínica, producción y calidad de leche (% de grasa, proteína y sólidos no solubles) y durante 18 meses Conteo de Células Somáticas (CCS/mL). Estas mediciones se realizaron mensualmente. La implementación del sistema HACCP en la rutina de ordeño, así como las buenas prácticas (BP) de Higiene de ordeño antes, durante y después, logró reducir el CCS/mL y mantenerlo por debajo de 200,000 CCS/mL después de ocho meses de seguimiento. El grado de afectación de la mastitis subclínica que tuvo la mayor frecuencia fueron las trazas (19.5 %). El nivel de mastitis subclínica, así como el CCS/mL no afectó la producción, contenido de grasa, proteína y sólidos no solubles.

Staphylococcus aureus se considera el principal agente causal de la mastitis bovina, que afecta a la producción de leche en las vacas. Para determinar la presencia de mastitis subclínica y la frecuencia de infección y la caracterización de los fenotipos presentes de S. aureus. Por conveniencia, se obtuvieron 580 muestras compuestas de leche de vacas del sistema de producción familiar a baja escala. Identificar los patógenos presentes en la infección asociada a la mastitis y caracterizar los fenotipos de S. aureus. Los resultados se evaluaron mediante la prueba de estimación de proporciones (p<0,05). La frecuencia de mastitis subclínicas fue del 24% y del 9% de mastitis clínicas en el total de muestras estudiadas (p<0,001), la infección por S. aureus representó el 20% de los agentes aislados con un rango de infección del 18 al 24% en rebaños lecheros de regiones municipales. La mastitis subclínica asociada a infección por S. aureus muestra una amplia distribución en hatos lecheros de producción familiar de baja escala en la zona centro del estado de México.

El objetivo de este trabajo fue evaluar la concentración de polifenoles, antocianinas, porcentaje de color polimérico y actividad antioxidante de jugos comerciales obtenidos a partir de diversos frutos ricos en estos compuestos y compararlo con la muestra de jugo de zarzamora tratada con microondas, seleccionada previamente por nuestro grupo de investigación. Se obtuvieron 30 jugos de marcas comerciales, tres de cada marca comercial, que se expenden en la ciudad de Xalapa, Veracruz, elaborados a partir de diversos frutos como manzana, uva, arándano, ciruela pasa, granada, zanahoria, cereza y zarzamora. Se determinó el contenido de polifenoles totales por el método de Folin-Ciocalteu, antocianinas monoméricas y porcentaje de color polimérico por el método diferencial de pH y actividad antioxidante y se comparó con el jugo de zarzamora tratado con microondas. El jugo comercial con mayor contenido de polifenoles y actividad antioxidante por el método de FRAP fue el jugo de ciruela, mientras que el jugo a base de zanahoria, manzana, cereza y mora mostró menor aporte de polifenoles y actividad antioxidante mediante el método DPPH. Los jugos evaluados (250 mL) aportan de 6.85-38.7% de la recomendación diaria de polifenoles, y éstos mostraron muy bajos niveles de antocianinas. Por otro lado, el jugo obtenido con microondas aporta el 70.9% de la ingesta diaria recomendada de polifenoles y más del 100% del requerimiento diario de antocianinas. Lo anterior sugiere el potencial de aplicación de las microondas en el proceso de elaboración de jugos a partir de frutos ricos en antocianinas permitiendo extraer mayor cantidad de estos compuestos que poseen propiedades antioxidantes.

The study aimed to investigate the impact of the COVID-19 pandemic on primary education in Cyprus and to discern the implications for the post-pandemic era, specifically focusing on the Emergency Remote Learning (ERL) experiences and reflections of upper primary students (ages 9-12). Grounded in socio-constructivist learning theory, which emphasizes the importance of active student engagement and social interaction in the learning process, the research explored the challenges students faced during the rapid shift to remote education. A mixed-methods design was employed, using an in-depth online survey that incorporated both quantitative and qualitative questions. Data were collected from a sample of 204 students selected through non-probability, convenience sampling. The analysis revealed that students experienced several challenges, including technology constraints, lack of interaction, and difficulty maintaining concentration, which are consistent with global findings on K-12 ERL. Among demographic factors, the type of school attended (public vs. private) had a significant influence on most aspects of students' ERL experience. Private school students reported more favourable conditions than their public school counterparts, which facilitated a smoother shift to both asynchronous and synchronous ERL, resulting in a more positive overall ERL experience. Regardless of the type of school attended, students overwhelmingly expressed a strong preference for face-to-face learning. Comparisons with other studies conducted in Cyprus during the same period involving older student age cohorts suggest significant age-related differences. The young students in our study encountered greater challenges during the transition to ERL, which can be attributed to their heightened need for scaffolding and external regulation to learn in the virtual space, as well as the higher importance they attached to the social aspects of school life taken away by ERL. Despite their largely negative experiences with ERL, a high proportion of the children advocated integrating the e-learning tools and technologies they got acquainted with during ERL into the normal context of schooling. These findings underscore the importance of further research into effective instructional strategies tailored to young learners in both online and blended learning settings. They also highlight the potential benefits of incorporating e-learning tools into conventional classrooms to enhance the teaching and learning process.
