ABSTRACT Wheat (Triticum aestivum) plays a vital role in global food security. Historical average yields in Brazil are below potential, and increasing wheat yield in Brazil will demand a thorough understanding of basic plant development processes, which can be achieved using process-based crop simulation models. The objective of this study was to calibrate and evaluate the performance of the WE-Streck model for simulating leaf emergence of spring wheat cultivars in the subtropics and tropics of Brazil. Field experiments during four years (2021, 2022, 2023, and 2024) were conducted with 13 wheat cultivars in four locations, three in the state of Rio Grande do Sul and one in the state of São Paulo, in the southern and southwestern regions of Brazil, respectively. The leaf number on the main culm was determined weekly using the Haun Scale until the flag leaf. The non-linear WE-Streck model for leaf appearance originally developed for winter wheat was used. The model was calibrated using a cross-validation approach using three sowing dates in April, May, and June 2021 in Santa Maria city, and model evaluation was with independent data from all other locations and sowing dates. The WE-Streck leaf emergence model had excellent performance in simulating the Haun Stage in spring wheat cultivars with different developmental cycles (from ultra early to late cycles), grown in different environments (subtropical and tropical), and with different N dressing management (timing and sources), with a root mean square error ranging from 0.10 to 0.71 leaves on the main culm.

RESUMO Os resultados apresentados fazem parte dos trabalhos realizados dentro do Programa de Pesquisa sobre Animais de Vida Livre, no período de 1992 a 1994. Através do microscópio eletrônico de transmissão, utilizando contrastação negativa, é descrita a visualização de partículas semelhantes a rotavírus em 3 das 15 amostras de fezes de gambás-de-orelhas-pretas (Didelphis marsupialis), procedentes da Reserva Florestal da Serra do Itapety, localizada no município de Mogi das Cruzes, Estado de São Paulo. A presença constante dessas partículas características, medindo em média 70nm de diâmetro, nas amostras fecais, de consistência anormalmente pastosa, sugere a possibilidade dos animais estarem na fase de convalescência da virose, ou de serem portadores latentes, ou mesmo, de servirem de reservatório ao vírus. Esse é o primeiro relato de rotavírus em marsupiais, na Mata Atlântica.

RESUMO Avaliou-se o perfil sorológico de 33 fêmeas bovinas vacinadas com a amostra padrão de Brucella abortus (B19), através da prova de imunodifusão em gel de ágar, comparativamente aos testes de soroaglutinação rápida em placa (SAR), soroaglutinação lenta em tµbos (SAT), antígeno acidificado (ATA) e 2-mercaptoetanol (2-ME), durante 24 meses pós-vacinais. Para a realização da prova de imunodifusão foi utilizado extrato polissacarídico (POLI O) obtido da amostra de B. abortus 1119-3. Somente um animal (3,0%) apresentou reação precipitante na imunodifusão, no 14u dia pós-vacinai. No 28u dia após a vacinação, 15 (45,4%) animais apresentaram reatividade na imunodifusão, com igual quantidade no 42u dia pós-vacinai. No 56U dia após a vacinação, verificou-se três animais (9,1%) positivos na imunodifusão e um (3,0%) com reação precipitante fraco-positiva, que se manteve detectável no 91º e 119º dia pós-vacinai; embora os demais animais demonstrassem negatividade na prova a partir do 91º dia após a imunização. Nos testes de SAR, SAT e 2-ME, os animais apresentaram títulos máximos entre o 14º e 42º dias após a vacinação, com declínio regular e contínuo após este período, e juntamente com o do ATA, foram considerados negativos ao redor de 10 meses pósvacinais. Dentre as provas utilizadas, a imunodifusão em gel de ágar contendo antígenos polissacarídeos, foi a que apresentou maior precocidade na ausência de reações positivas (5 meses pós-vacinais).

ABSTRACT Basil produces essential oils of economic interest, but producing this species in semi-arid regions is a challenge. Brazil has specific edaphoclimatic characteristics that varying with region. The objective was to study the yield and chemical composition of essential oils of Ocimum basilicum L. in a greenhouse in Bahia, Brazil, subjected to 24, 72, 96, 120 and 144 hours without irrigation, corresponding to the 1st, 3rd, 4th, 5th and 6th days, in order to evaluate the optimization of essential oil removal, production and chemical composition. Data on height and number of leaves of the species and climatic conditions of the region were collected. Essential oils were obtained by hydrodistillation, and the identification and quantification of chemical compounds was performed by GC-FID. Proline content, fresh and dry biomass, essential oil content and chemical composition were evaluated. Water stress treatments caused reduction of 9.31% to 27.32% in fresh biomass, an increase of ~50% in dry biomass and there was a marked increase in proline production as an indication of stress. Essential oil content was proportional to irrigation time, and after 72 hours it no longer showed a significant difference. It was observed that the best basil essential oil content is obtained on the third day of water suspension and the chemical composition of the essential oils changed subtly, with the major compounds being linalool and eugenol. It is recommended to grow basil in a greenhouse with 40% shade net and harvest at 62 days after transplanting under a six-day water suspension.

ABSTRACT The objective of this study was to evaluate the physiology and growth of guava cv. Paluma as a function of irrigation with saline water and foliar application of ascorbic acid. The study was conducted using a randomized block experimental design in a 5 × 4 factorial scheme, whose treatments were formed by combining five levels of electrical conductivity of irrigation water - ECw (0.3, 1.2, 1.9, 2.6, and 3.3 dS m-1), associated with four concentrations of ascorbic acid - AsA (0, 30, 60, and 90 mM), with three replicates and one plant per plot. Stem diameter, crown volume, vegetative vigor index, photosynthetic pigment contents, photochemical efficiency, electrolyte leakage, and relative water content were evaluated. Ascorbic acid at concentration of 60 mM increased electrolyte leakage and relative water content in plants under ECw of 3.2 and 2.9 dS m-1, respectively. AsA concentration of 90 mM stimulated the biosynthesis of chlorophyll a, chlorophyll b, and total chlorophyll of guava plants grown under water salinity of 3.3 dS m-1. Salinity above 0.3 dS m-1 reduced chlorophyll a fluorescence, crown volume, and vegetative vigor index of guava. Foliar application of 30 mM ascorbic acid increased the quantum efficiency of photosystem II up to ECw of 2.5 dS m-1. The beneficial effect of ascorbic acid was obtained under ECw of 0.3 dS m-1.

ABSTRACT The black sucupira, Bowdichia virgilioides Kunth (Fabaceae), is a native Brazilian tree species with a wide geographical distribution and significant economic potential for timber, landscaping, and restoration of degraded areas. The objective of this study was to test and evaluate the viability, vigor, and germination of B. virgilioides, with an emphasis on adopting alternative methods to overcome seed coat dormancy. The methodology of using 70% alcohol combined with direct fire for 60 s proved effective in breaking dormancy. Additionally, seed color influenced viability and germination, with lighter-colored seeds (red and orange) exhibiting better germination rates. However, the use of controlled fires to overcome seed dormancy is a more accessible and safer method than other widely used methodologies.

Abstract In our study, we conducted a thorough analysis of the spectral characteristics of a D-shaped surface plasmon resonance (SPR) photonic crystal fiber (PCF) refractive index sensor, incorporating a full width at half maximum (FWHM) analysis. We explored four distinct plasmonic materials-silver (Ag), gold (Au), Ga-doped zinc oxide (GZO), and an Ag-nanowire metamaterial-to understand their impact on sensor performance. Our investigation encompassed a comprehensive theoretical modeling and analysis, aiming to unravel the intricate relationship between material composition, sensor geometry, and spectral response. By scrutinizing the sensing properties offered by each material, we laid the groundwork for designing multiplasmonic resonance sensors. Our findings provide valuable insights into how different materials can be harnessed to tailor SPR sensing platforms for diverse applications and environmental conditions, fostering the development of advanced and adaptable detection systems. This research not only advances our understanding of the fundamental principles governing SPR sensor performance but also underscores the potential for leveraging varied plasmonic materials to engineer bespoke sensing solutions optimized for specific requirements and performance metrics.
Common statistical and methodological errors in rejected manuscripts: the case of RBSO
Authors: Maia André Luis Santiago
Published: February 2025

Abstract The Revista Brasileira de Saúde Ocupacional (RBSO) receives several manuscripts with studies involving quantitative methods in Occupational Safety and Health (OSH). However, many submissions present methodological and statistical errors that compromise their acceptance. Lack of clarity in results and inadequate use of statistical methods are recurring issues. Insufficient description of methodologies, poorly justified statistical analyses, and unwarranted extrapolation of results are also frequent. This editorial note discusses common errors observed in manuscripts rejected by RBSO, with the aim of improving the quality of publications in the OHS field.

Published: February 2025

ABSTRACT Gridded meteorological datasets represent a valuable alternative for hydrometeorological applications, especially in areas with limited ground observations. However, it is important to evaluate these datasets to quantify their accuracy, error, and bias in estimates. The objective of this research was to assess the hydrological performance of gridded meteorological products in Peruvian Altiplano basins. Three evaluation approaches were employed: 1) pixel-to-point, 2) basin-averaged values, and 3) as forcings in hydrological modeling. Using precipitation (P) and potential evapotranspiration (PET) data from AgERA5, ERA5-Land, MERRA-2, and PERSIANN-CDR, comparisons were made with 33 local meteorological stations using statistical metrics such as correlation coefficient (CC), root mean square error (RMSE), and percentage bias (PBIAS). Additionally, the GR4J hydrological model was employed in four watersheds to assess model performance with different data combinations. Results showed that AgERA5 and ERA5-Land excelled in daily precipitation estimation, while MERRA-2 had the lowest PET bias. Using reference data for P and PET as model forcings yielded consistent results across basins. However, the performance declined when using gridded products for both P and PET, revealing significant limitations in replicating hydrological processes and emphasizing the need to enhance these products for areas with limited observational data.

Abstract Introduction Migration involves the displacement of people from their usual place of residence, leading to identity and adaptation challenges. In Chile, the number of migrants has increased, notably Haitian women who face discrimination and racism, affecting their mental health and occupational performance. Objective This study analyzes the occupational performance in the leisure occupations of Haitian migrant women in the metropolitan region of Chile. Method A phenomenological and qualitative approach with a descriptive design was employed, using semi-structured interviews for data collection. The study was conducted with three migrant women residing in the Metropolitan Region of Chile. Results The results show that in private spaces, home care and child-rearing are predominant, while leisure occupations are prioritized in public spaces. The choice of these activities is influenced by various factors such as available time, motivation, economic, climatic, and racial aspects, among others. Conclusion Despite the importance attributed to leisure occupations, they are conditioned and hierarchized, highlighting the need to enhance facilitators like motivation to overcome identified contextual barriers. This qualitative study points out aspects that could be reconsidered for future research.

ABSTRACT Introduction: Degenerative disease is a complex condition to treat, given the multiple possibilities for treatment and the fact that the population with the highest prevalence of the condition tends to be older and more frail. Endoscopic techniques are increasingly used to treat this group of pathologies to minimize the risks and improve patient recovery. Methods: Systematic review and meta-analysis, with the keywords used in the search engines: “adjacent segment disease” and “endoscopic surgery”. Results: 9 articles, totaling ten entries, were included in the quantitative analysis. The studies, in general, were of low quality. The number of complications per 1000 patients was 94. The average ODI value at the last follow-up point was 12 points, with back VAS averaging 2.17 and leg VAS averaging 1.91. Conclusion: Endoscopic techniques potentially improve patients’ clinical outcomes and have a low complication rate. However, higher-quality studies are needed to visualize the real impact of the technique on the treatment of adjacent-level pathologies. Level of Evidence I; Systematic Revision and Metanalysis.

ABSTRACT This review aims to update the cervical laminoplasty techniques described in the literature and perform a systematic review of the open-door (ODL) and French-door (FDL) laminoplasties. A literature review was conducted on the Pubmed and Scielo platforms. This study was separated into two phases. The first section reviewed the laminoplasty techniques described in the literature. In this phase, a literature review was carried out using the descriptor “cervical laminoplasty”, employing “clinical trial”, “meta-analysis”, “review,” and “systematic review” as filters. The second section was a systematic review of the two most-studied techniques, the open-door and French-door laminoplasties. In this phase, a review was carried out using the descriptors “cervical laminoplasty”, “open-door” and “French-door” or “double-door”, employing “meta-analysis” and “review” as filters. In both phases, no limits were defined on the period. The first laminoplasty was described in 1973 and, since then, there have been, at least, six more techniques described that involve opening the spinal canal. Other studies report slight modifications in the type of spine access or details related to the osteotomy technique. Five systematic reviews were performed comparing the ODL and FDL. Only two of them analyzed common variables, and their results were divergent. Both ODL and FDL achieve favorable clinical and radiological results for the patient, and it is not yet possible to say whether one is better than the other.

Background:

Chronic kidney disease (CKD) is a growing global public health issue. Physical exercise mitigates several kidney-related pathophysiological pathways, yet its impact on kidney function remains underexplored. We investigated the dose-response effect of physical exercise on kidney function preservation in older adults.

Methods:

Post-hoc analysis of the Generation 100 Study, a 5-year open-label, randomized, parallel-arm clinical trial conducted from 2012 to 2018 in Trondheim, Norway. All inhabitants aged 70-77 years were invited (n=6,966). Main exclusion criteria were dementia; severe, uncontrolled cardiovascular disease or hypertension; or conditions precluding exercise. The control group (n=385) received information on national physical activity recommendations. Intervention groups underwent supervised moderate-intensity continuous training (70% of peak heart rate) for 50 minutes (n=380) twice weekly for five years or high-intensity interval training (90% of peak heart rate) for 4 minutes x4 (n=391) twice weekly for five years. The primary outcome was cystatin C-based rapid eGFR decline (>5mL/min/1.73m2 per year).

Results:

A total of 1,156 participants were randomized with median (interquartile range) age 72 (3) years and eGFR 95 (20) mL/min/1.73 m2. Oxygen uptake increased by 1.8, 2.3, and 3.3 mL/kg/min in the control, moderate-intensity, and high-intensity groups. Rapid eGFR decline occurred in 117 (30%), 108 (28%), and 92 (23%) participants, respectively. Compared to controls, relative risk (RR) was 0.93 (0.75-1.16) for moderate-intensity and 0.75 (95% CI 0.59-0.95) for high-intensity, demonstrating a significant dose-response relationship (P for trend 0.02). In observational analyses, participants with decreasing moderate-vigorous activity (> -20 minute/week) had RR 1.30 (95% CI 0.93-1.83) for rapid eGFR decline, while those with increasing activity (> +20 minutes/week) had RR 0.73 (0.53-0.99) compared to stable activity after adjusting for baseline age, sex, VO2peak and eGFR.

Conclusions:

High-intensity interval training significantly reduced the risk of rapid eGFR decline in older adults.

Arterial hypertension is an oxidative stress, as a pathogenetic target for the treatment of chronic cerebrovascular insufficiency
Authors: Chukanova E.I. , Chukanova A.S. , Andrianov D.D.
Published: February 2025

The increase in the development of arterial hypertension (AH), as the main modifiable risk factor for the development of acute and chronic cerebral circulatory insufficiency, often leading to a progressive decrease in cognitive status and physical activity, requires early detection and effective pathogenetic therapy. The breadth of therapeutic effects of the drug Mexidol (ethylmethylhydroxypyridine succinate) due to the multifactorial nature of its pathogenetic effects contributes to its widespread use. The safe profile of Mexidol use and the absence of drug interaction makes it relevant in the complex treatment of patients with cardiovascular diseases.

Published: February 2025

Course development at online distance learning (ODL) universities is frequently undertaken as a formalised collaborative process. In line with this, the University of South Africa (Unisa) has adopted a framework for a ‘team approach’ to course development, to which lecturers are key contributors, and who are supported by other specialists. The course development process has several embedded quality assurance mechanisms, which were derived from relevant literature on collaborative course development practices and quality standards. At Unisa, there has been no systematic research into the effectiveness of the quality mechanisms from lecturers' perspective. An exploratory study was conceptualised to obtain feedback from lecturers on the value of different quality mechanisms. The research posed the question: Which quality mechanisms promote successful course development, in the Unisa context, from a lecturer's perspective? A mixed-method approach was used. It involved a survey among lecturers to gauge the relative value attached to different quality mechanisms. Follow-up focus group sessions were conducted to further explore emerging issues. The results of the study highlighted the importance of formative feedback, including feedback from knowledgeable peers inside and outside the university. Furthermore, the allocation of sufficient resources was regarded as critical. On the basis of the findings, a model for quality assurance in collaborative course development that integrates the lecturers’ perspectives is suggested.

High-purity rare earth metal dysprosium was subjected to a single-pass thermal compression test at temperatures ranging from 300 °C to 700 °C and strain rates ranging from 0.1 s–1 to 10 s–1 using an MMS-200 thermal simulation testing machine. The true stress-strain curves, macro and microstructure of dysprosium were analyzed, leading to the establishment of processing maps and constitutive equation for dysprosium. Results revealed that the stress of dysprosium decreased with increasing deformation temperature and decreasing strain rate. Moreover, as the strain rate reached 5 s–1, the stress-strain curve gradually transitioned from dynamic recovery to dynamic recrystallization, with a more pronounced softening behavior observed at higher strain rates. Based on the processing diagram and sample microstructure analysis, it was determined that the optimal deformation range for dysprosium is between 350 °C and 500 °C at a strain rate of 1–10 s–1.

In this study, aluminium alloys of AA6082 and AA7075 series were welded with resistance spot welding. Effects of welding current intensity, welding time, and electrode pressure on the tensile strength and microstructure were examined, and their optimized values were determined using the Taguchi method. While performing optimization, the L24 orthogonal array was used with the Taguchi method. With this array, the signal/noise (S/N) ratio became the determining factor in controlling the optimization results. Comparing the experimental procedures and analysis results, the results obtained from the real application and Taguchi analysis were found out to be similar.

La transizione menopausale comporta cambiamenti sfavorevoli per la salute cardio-metabolica che contribuiscono all’aumento del rischio cardiovascolare nelle donne a partire dalla quinta decade di vita. La terapia ormonale della menopausa (MHT) è un’opzione sicura per la maggior parte delle donne sane che la iniziano in prossimità della menopausa per il trattamento dei sintomi vasomotori e di altre manifestazioni della menopausa. La MHT non ha però dimostrato di essere efficace all’unico scopo di prevenzione primaria o secondaria delle malattie cardiovascolari, ove si eccettui il contesto specifico della menopausa precoce/insufficienza ovarica prematura, condizioni patologiche caratterizzate da ipoestrogenismo in giovane età, che devono essere gestite con un adeguato trattamento estrogenico per ridurre la morbidità e la mortalità cardiovascolare e le altre complicanze a lungo termine. La prescrizione della MHT può rappresentare una sfida nelle donne con fattori di rischio cardiovascolare e un approccio individualizzato dovrebbe sempre guidare un progetto terapeutico e preventivo di ampio respiro al fine di curare i sintomi promuovendo al tempo stesso la salute a lungo termine. La presente revisione narrativa riassume le principali evidenze su cui si basano i principi di prescrizione della MHT nel contesto dell’ottimizzazione della salute cardio-metabolica nella donna di mezza età.

SHEVCHENKO'S APHORISMS AS REPRESENTATIVES OF NEW MEDIA MEANINGS
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Syzonov Dmytro
Published: February 2025

B a c k g r o u n d . The article identifies and analyzes new reflections on Taras Shevchenko's texts in the media space. Emphasis is placed on Shevchenko's aphorisms, which acquire new meanings in mass communication, in particular, socio-political, economic, artistic and cultural processes in Ukraine are emphasized, which are accompanied by T. Shevchenko's texts to strengthen the argumentation and facts of the presented material. The use of Shevchenko's aphorism is based on the background knowledge of the recipients, because the intended effect of impact on the audience is possible only with the "correct" construction of the media text.
M e t h o d s . Media monitoring and information screening methods were used to analyze the information space of Ukraine. Traditionally, in media linguistics, such methods make it possible to diagnose media sources with regard to language material, in particular, aphorisms. We screened the infospace in times of socio161 political changes (2000s), which helped prove the universal role of Shevchenko's aphorisms in media texts: this applies to both positive (cultural and educational events and projects, sports competitions, etc.) and negative (social and political crises, war and revolutions, etc.) events in which T. Shevchenko's aphorisms are used as precedent phenomena.
R e s u l t s . Shevchenko's aphorisms are used in headlines and leads (subheadings of media article elements) to attract attention and have an implicit influence, in the headlines we notice another purpose of using aphorisms – emotional and expressive. Often in the headlines, aphorisms are used as appeals to social reality: we are actually talking about aphorisms-intertextems, which are designed to describe modernity based on the authoritative opinion of Shevchenko, actualized in new conditions.
C o n c l u s i o n s . Having analyzed the array of media texts using Shevchenko's aphorisms, we can state that aphorisms-intertextems related to Ukraine are particularly relevant – "There is no Ukraine in the world...", "Battle on – and win your battle!", "When I am dead, bury me In my beloved Ukraine", etc. They are able to adapt to different social contexts (revolutionary events, political processes, economic and legal changes, etc.), which allow forming a "spiral" of meanings, repeating rhythmically at different times. And as a result, new meanings are formed, which are successfully reinterpreted by the media.
