ABSTRACT Exposing seeds to agents that elicit tolerance to abiotic stress, such as phytohormones and organic acids, during hydration and dehydration cycles can determine their response to later stimuli, e.g. exposure to salt stress. The aim of this study was to evaluate the action of priming cycles with different eliciting agents of salt stress tolerance on seeds of the cowpea varieties Sempre Verde and Pingo de Ouro. The seeds were subjected to the following treatments: 0.0 mM NaCl (control); 100 mM NaCl (salt stress); salt stress + three seed-priming cycles (PC) in water; salt stress + PC in gibberellic acid; salt stress + PC in hydrogen peroxide; salt stress + PC in salicylic acid; salt stress + PC in ascorbic acid. The following variables were analysed: germination, growth, dry weight, salt tolerance index, total soluble sugars, total free amino acids and proline. Salt stress (100 mM NaCl) reduced germination, length and biomass accumulation in the Sempre Verde and Pingo de Ouro varieties. These showed the best response to the priming cycles with gibberellic and salicylic acids, which promoted greater germination potential, length and biomass under a salt stress of 100 mM NaCl, affording greater tolerance via osmotic regulation, especially in the Sempre Verde variety. stimuli eg e g e.g treatments 00 0 0. control (control) 10 stress) seedpriming seed (PC water acid peroxide analysed growth weight index sugars proline (10 potential regulation variety (control 1 (1 (

Abstract Self-healing consists of closing cracks and recovering the watertight properties of cement-based materials and can occur by hydration of the materials of the mixture (autogenous) or by materials added to the mixture for this purpose (autonomous). This study consists of the use of stimulated self-healing as a way of mitigating sulfate attack (sodium and magnesium), with the evaluation of the influence of crystalline admixture in this process. For that, cycles of sulfate attack and self-healing (by wetting and drying cycles in water) were performed, aiming to evaluate the behavior of mortars with three types of cement: Portland, supersulfated, and alkali-activated. The results showed that self-healing was not sufficient to close cracks due to sulfate attack. This behavior was associated with the hypothesis that the high calcium content of the crystalline admixture reacted with the sulfates and formed expansive products, increasing the attack rate.

Resumo A autocicatrização consiste no fechamento de fissuras e recuperação da estanqueidade dos materiais à base de cimento e pode ocorrer por hidratação dos materiais da mistura (autógena) ou por materiais adicionados à mistura para esse fim (autônoma). Este estudo consiste na utilização de autocicatrização autógena estimulada como forma de atenuar o ataque por sulfatos (sódio e magnésio), com a avaliação da influência de adição cristalizante neste processo. Para isso, foram realizados ciclos de ataque sulfatado e autocicatrização (ciclos de molhagem e secagem), com o objetivo de avaliar o comportamento de argamassas com três tipos de cimento: Portland, supersulfatado e álcali ativado. Os resultados mostraram que a autocicatrização não foi suficiente para fechar trincas devido ao ataque por sulfatos. Esse comportamento foi associado à hipótese de que o alto teor de cálcio da adição cristalizante reagiu com os sulfatos e formou produtos expansivos, aumentando a taxa de ataque.

Abstract Given the environmental impacts associated with the production of conventional Portland cement, the study of special cements with reduced environmental impact has been a trend. In this context, cements containing ye'elimite (YCC) stand out due to their low CO 2 emissions. Despite the environmental advantages, the high demand for aluminum economically limits the production of these cements.An alternative to making its production feasible is using residual raw materials as a source of Al 2 O 3 , such as SFCC (spent fluidized catalytic cracking).In view of this, this work aims to evaluate hydration at the initial age of cements. For this, six clinkers were produced with different ye'elimite contents, with and without SFCC. These were characterized by XRD/Rietveld. The pastes were evaluated by TG/DTG and XRD/Rietveld to understand the hydration mechanism on the third day of these cements. It was possible to synthesize the main phases of YCC, in clinkers with and without SFCC. In addition, at the age evaluated, the pastes with and without SFCC presented comparable phase composition, indicating the potential for co-processing this residue. cement trend context yeelimite ye elimite YCC (YCC emissions advantages cementsAn An spent cracking.In crackingIn cracking .In contents XRDRietveld XRD Rietveld TGDTG TG DTG addition composition coprocessing co processing residue

Resumo Diante dos impactos ambientais associados à produção do cimento Portland convencional, o estudo de cimentos especiais de reduzido impacto ambiental tem sido uma tendência. Neste contexto, os cimentos contendo ye’elimita (YCC) se destacam devido à baixa emissão de CO2. Apesar das vantagens ambientais, a alta demanda por alumínio limita economicamente a produção destes cimentos. Uma alternativa para viabilizar a sua produção é o uso de matérias-primas residuais como fonte de Al2O3, a exemplo do SFCC (catalizador gasto do craqueamento catalítico de leito fluidizado). Diante disso, este trabalho tem como objetivo avaliar a hidratação na idade inicial de cimentos YCC produzidos a partir do coprocessamento do SFCC. Para isso, foram produzidos seis clínqueres com diferentes teores de ye’elimita, com e sem SFCC. Estes foram caracterizados por DRX/Rietveld. As pastas foram avaliadas por TG/DTG e DRX/Rietveld para compreender o mecanismo de hidratação em idade inicial destes cimentos. Foi possível sintetizar as principais fases dos YCC, nos clínqueres com e sem SFCC. Além disso, na idade avaliada, as pastas com e sem SFCC apresentaram composição de fases comparáveis indicando o potencial de coprocessamento do SFCC neste tipo de cimento. convencional tendência contexto yeelimita ye elimita (YCC CO2 CO matériasprimas matérias primas Al2O3 AlO Al O catalizador fluidizado. fluidizado . fluidizado) disso isso yeelimita, elimita, DRXRietveld DRX Rietveld TGDTG TG DTG avaliada Al2O

Abstract Textile sludge is a waste from the effluent treatment of textile laundries and its incorporation into alternative materials has been proposed as a possibility for its disposal. A systematic search was carried out in literature from this perspective, aiming to observe concentrations of waste material and its preparation, matrices used, technological performance and immobilization of textile waste. The matrices used were mortars, concretes and ceramic bricks, in general, deleterious effects were observed on mechanical characteristics of the materials produced. In concrete and mortars, the fineness had an impact on increase in water demand, which increased mixtures porosity; and organic matter and heavy metals, in cement hydration. Recent studies therefore proposed waste material pre-treatment as a favorable alternative. Increases in porosity also occurred in ceramic bricks, however, due to high organic matter content. Regarding waste immobilization, cementitious materials showed satisfactory performance; ceramic bricks, on the other hand, obtained some results outside the normative limits. Therefore, it is necessary to expand discussions regarding the pre-treatment carried out on textile sludge, as well as its impacts on mechanical and environmental performance. disposal perspective preparation mortars bricks general produced demand metals hydration pretreatment pre however content hand limits Therefore

Resumo Olodo têxtil é um resíduo do tratamento do efluente das lavanderias têxteis e sua incorporação em materiais alternativos tem sido proposta como possibilidade para sua destinação. Foi realizada uma busca sistemática na literatura nesta perspectiva, visando observar as concentrações de material residual e seu preparo, as matrizes utilizadas, o desempenho tecnológico e imobilização do resíduo têxtil. As matrizes empregadas foram argamassas, concretos e tijolos cerâmicos, sendo observados, de maneira geral, efeitos deletérios nas características mecânicas dos materiais produzidos. Em concretos e argamassas, a finura impactou no aumento da demanda de água, o que elevou a porosidade das misturas; e a matéria orgânica e metais pesados, na hidratação do cimento. Estudos recentes propuseram, então, o pré-tratamento do material residual como uma alternativa favorável. Incrementos na porosidade também ocorreram nos tijolos cerâmicos, porém, devido ao elevado teor de matéria orgânica. Quanto a imobilização do resíduo, os materiais cimentícios apresentaram desempenho satisfatório; já os tijolos cerâmicos, obtiveram alguns resultados fora dos limites normativos. Portanto, é necessário ampliar as discussões quanto ao pré-tratamento realizado no lodo têxtil, bem como seus impactos no desempenho mecânico e ambiental. destinação perspectiva preparo utilizadas argamassas cerâmicos observados geral produzidos água misturas pesados cimento propuseram então prétratamento pré favorável porém satisfatório normativos Portanto ambiental

Abstract The results obtained from the study of an agglutinated mass made up of seeds and soft woody structures with different degrees of charring are presented. This mass was recovered in situ, close to a gold object, in structure 34 of El Molino site (Hualfín Valley), where a human burial was also located. From the analysis of a sample of 104 seeds, it was observed that the highest percentage of these belong to Chenopodium carnosolum, an agricultural weed known as ajara, which is associated with the cultivation of quinoa; a single specimen was identified as cf. Ch. hircinum, while another could not be identified taxonomically. Furthermore, almost all seeds were immature at the time of harvesting and show evidence of enhancement and hydration processes. In view of the findings context, it is considered that the culinary preparation analyzed could have been involved in ceremonies destined for the ancestors and could have been part of the rituals linked to the closing of the cycle. The possible consumption of ajara during a ritual event manifests an important significance and could therefore be considered as more than a weed.

Resumen Se presentan los resultados obtenidos del estudio de una masa aglutinada constituida por semillas y estructuras leñosas blandas carbonizadas y sin carbonizar, recuperada próxima a un objeto de oro en el recinto 34 del sitio El Molino (Valle de Hualfín), en el que se localizó, además, un entierro humano. El análisis de una muestra de 104 semillas condujo a determinar que el mayor porcentaje pertenece a Chenopodium carnosolum, maleza agrícola conocida como ajara que se asocia al cultivo de las quinoas; un solo ejemplar se identificó como posible Ch. hircinum, mientras que otro no pudo identificarse taxonómicamente. Asimismo, casi la totalidad de las semillas estudiadas estaban inmaduras al momento de su cosecha y tienen evidencia de haber sufrido un procesamiento de desaponificación e hidratación. Teniendo en cuenta el contexto de hallazgo, se considera que esta masa corresponde a una preparación culinaria, la cual podría haber estado involucrada en ceremonias destinadas a los antepasados y haber sido parte de las ritualidades vinculadas a los cierres de ciclo. Asimismo, el posible consumo de ajara durante un evento ritual manifiesta una importante significación, y, por lo tanto, podría considerarse como más que una maleza.

Se formularon cinco fluidos de perforación a 3 lbm/bbl de la pulpa. 3,6 y 9 lbm/bbl de cáscara del cacao y un fluido con 3 lbm/bbl de glicol correspondiente al fluido estándar, adicionalmente se determinan pruebas químicas en el filtrado del fluido La evaluación de formulaciones de fluidos de perforación con inhibidores naturales a 3 lbm/bbl se obtiene hinchamiento lineal de la pulpa 41,4%, cáscara 56,35% comparándolo con el inhibidor comercial glicol 45,07%; al filtrado del fluido de perforación que se evalúa a través del contenido de calcio es de 2080 mg/l para la pulpa. La pulpa de cacao tiene mejores propiedades inhibitorias que la cáscara y la semilla, sin embargo, al ser incorporada al fluido de perforación, el alto contenido de calcio interfiere en las propiedades físico químicas requeridas por un fluido de perforación.

Abstract The stability of the well depends on the control of clay hydration in the geological formations; the cocoa parts were evaluated as an inhibitory additive in drilling fluids, replacing glycol. an additive in drilling fluids, replacing glycol (a commercial clay inhibitor). The experimental scientific method was used to evaluate the inhibitory property (linear swelling reference bentonite in fresh water) of the different concentrations of cocoa fruit and glycol, selecting the lowest percentages. Five drilling fluids were formulated at 3 lbm/bbl of slurry. 3.6 and 9 lbm/bbl of cocoa shell and a fluid with 3 lbm/bbl of glycol corresponding to the standard fluid; additionally, chemical tests were determined in the fluid filtration. The evaluation of drilling fluid formulations with natural inhibitors at 3 lbm/bbl obtained linear swelling of the pulp (41.4%) and shell (56.35%) compared to the commercial inhibitor glycol (45.07%); drilling fluid filtrate that is evaluated through calcium content is 2080 mg/l for pulp. Cocoa pulp has better inhibitory properties than the cocoa shell and seed, making it work as a clay inhibitor. However, when incorporated into the drilling fluid, the high calcium content interferes with the physical and chemical properties required by the drilling fluid.

Abstract The probability of influencing the skin microbiome for addressing skin disorders opens a novel aisle of therapy. This study aimed to evaluate the efficacy of skin microbiota transplantation (sMt) for cutaneous adverse food reactions (caFr) in dogs. Ten client-owned dogs with caFr were included in the study. Unenriched heterologous sMt was performed using Nivea Skin Refining Clear-Up Strips (N-cUs). The bacterial microbiota of skin samples was analysed by next-generation sequencing of the 16S rRNA gene. Other relevant biomarkers were involved in VAS (visual analogue scale of pruritus score), CADESI-04 (canine atopic dermatitis extent and severity index) and epidermal corneometric analysis. Increased Faecalibacterium (0 to 1.9 %), Peptoclostridium (5.49 % to 9.11 %) and Collinsella (0.65 % to 8.91 %), and decreased Fusobacterium (19.16 % to 9.06 %), Porphyromona (8.75 % to 0.13 %), Streptococcus (1.63 % to 0.14 %) and Staphylococcus (1.09 % to 0.49 %) was evidenced before and after sMt, respectively. Treatment with sMt effectively controlled clinical signs and drastically reduced median VAS pruritus (6.5 vs. 2) and CADESI-04 scores (74.50±22.62 to 19.30±11.30) (p<0,001). In addition, skin pH and hydration values were improved (p<0,001) after sMt. The heterologous and unenriched sMt with N-cUs could be responsible for the clinical recovery observed in this study.

Resumen La probabilidad de influir en el microbioma de la piel para abordar trastornos dermatológicos abre una nueva vía de terapia. El objetivo del presente trabajo fue evaluar la eficacia del trasplante de microbiota cutánea (sMt) en diez perros con reacciones en piel, adversas a los alimentos (caFr). Se realizó un sMt heterólogo no enriquecido mediante el uso de tiras clarificadoras Nivea Skin Refining Clear-Up (N-cUs). Se prefirió la secuenciación de próxima generación para investigar la microbiota bacteriana en las muestras de piel de los animales estudiados. Otros biomarcadores relevantes estuvieron involucrados en la puntuación de prurito VAS, CADESI-04 y análisis corneométrico epidérmico (hidratación y pH). El gen 16S rRNA clasificó con éxito la presencia de un aumento de Faecalibacterium (0 a 1,9%), Peptoclostridium (5,49 % a 9,11 %) y Collinsella (0,65 % a 8,91 %), mientras que se observó una disminución de Fusobacterium (19,16 % a 9,06 %), Porphyromonas (8,75 % a 0,13 %), Streptococcus (1,63 % a 0,14 %) y Staphylococcus (1,09 % a 0,49 %), antes y después del sMt. El tratamiento con sMt controló eficazmente los signos clínicos y redujo drásticamente la mediana del prurito VAS (6,5 vs. 2) y las puntuaciones CADESI-04 (74,50±22,62 a 19,30±11,30) (p<0,001). Además, tanto el pH de la piel como los valores de hidratación se vieron alterados (p<0,001) después del sMt. El sMt heterólogo y no enriquecido con N-cUs podría ser responsable de la recuperación clínica observada en este estudio

ABSTRACT The aim of this work was to evaluate the hydric status and serum cortisol concentration in horses during two cultural horseback rides in the municipalities of Granada and Acacías in the department of Meta (Colombia). For this, 88 animals were selected at convenience (44 per ride), taking blood samples 1 h before starting the ride (T0) and 15 min after finishing the ride (T1). In addition, a clinical examination was conducted to determine their hydric status (humidity of the mucous membranes, capillary refill time, skin turgor and eyeball retraction). In the blood test, micro haematocrit, total serum proteins and cortisol concentration were determined. The results of the variables between the two times were compared with the Shapiro Wilks and Wilcoxon tests. The Spearman test determined the correlations between age and sex with serum cortisol. There were no significant differences between the hydric status and the times evaluated; however, micro haematocrit, total serum proteins and cortisol presented lower values at T0 (p<0.001). On the other hand, no significant correlations were found between serum cortisol concentration with age and sex. The results suggest that cultural horseback riding is a stressful activity for the animal, determined by the significant increase in serum cortisol, with a tendency toward haemoconcentration that emphasizes the importance of correct hydration of horses before, during and after these events.

RESUMEN El propósito de este trabajo fue evaluar el estatus hídrico y la concentración de cortisol sérico en equinos durante dos cabalgatas culturales en los municipios de Granada y Acacías del departamento del Meta (Colombia). Se seleccionaron 88 animales a conveniencia (44 por cabalgata), tomando muestras de sangre 1 h antes de iniciar la cabalgata (T0) y 15 min después de terminar la cabalgata (T1), además de un examen clínico para determinar su estatus hídrico (humedad de las mucosas, tiempo de llenado capilar, turgencia de la piel y la retracción del globo ocular). En el análisis de sangre se determinó el micro hematocrito, proteínas séricas totales y concentración de cortisol. Los resultados de las variables entre los dos tiempos se compararon con las pruebas de Shapiro Wilks y de Wilcoxon. La prueba de Spearman determinó las correlaciones entre edad y sexo con el cortisol sérico. No hubo diferencias significativas entre el estatus hídrico con los tiempos evaluados; sin embargo, el micro hematocrito, proteínas séricas totales y cortisol presentaron valores menores en T0 (p<0.001). Por otro lado, no se encontraron correlaciones significativas entre la concentración sérica de cortisol con la edad y el sexo. Los resultados sugieren que las cabalgatas culturales son una actividad estresante para el animal, determinada por el incremento significativo de cortisol sérico, habiendo una tendencia a la hemoconcentración que recalca la importancia de la correcta hidratación de los equinos antes, durante y después de estos eventos de exigencia física.

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04–1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11–16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36–0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

ABSTRACT Objective: The objectives of this study were to describe the first pediatric case of cold agglutinin syndrome (CAS) triggered by human adenovirus and review the literature. Case description: This case report involves a previously healthy, 2½-year-old female child with human adenovirus isolated in a nasal swab. At 72 h after admission, the patient progressed to a severe episode of anemia (hemoglobin level: 2.6 g/dL). The laboratory findings were consistent with CAS. The patient received blood transfusion, vitamin supplementation, adequate hydration, and thermal protection. At her last follow-up, 1 year after her initial presentation, she remains clinically well without signs of hemolysis. Comments: While severe CAS is extremely uncommon in the pediatric emergency department, human adenovirus infection is a common illness in pediatrics. Recently, the adenovirus has been associated with new complications (acute hepatitis and fulminant liver failure). Pediatric physicians and hematologists should be aware of unusual evolution, signs, and symptoms of this infection that warrant more urgent medical attention. In this case, the hematologic complication suspicion was the key to early diagnosis and adequate management.

RESUMO Objetivo: Descrever o primeiro caso pediátrico de síndrome da crioaglutinina desencadeado por adenovírus humano e revisar a literatura. Descrição do caso: Paciente do sexo feminino, dois anos e seis meses, previamente hígida e diagnosticada com adenovírus humano isolado em swab nasal. Após 72 horas da admissão, a paciente evoluiu com quadro de anemia grave (hemoglobina de 2,6 g/dL). Os achados laboratoriais foram compatíveis com síndrome da crioaglutinina. A paciente recebeu transfusão de concentrado de hemácias, suplementação vitamínica, hidratação adequada e proteção térmica. Em seu último retorno ambulatorial, um ano após a apresentação inicial, permanecia clinicamente bem, sem sinais de hemólise. Comentários: Enquanto a síndrome da crioaglutinina grave é extremamente incomum na emergência pediátrica, a infecção por adenovírus humano é um quadro comum na infância. Recentemente, o adenovírus tem sido associado a novas complicações, e pediatras e hematologistas devem ficar atentos à possibilidade de uma evolução incomum dessa infecção e dos sinais e sintomas que possam necessitar de atenção urgente. No caso apresentado, a suspeita da complicação hematológica foi a chave para o diagnóstico precoce e seu manejo adequado.

Abstract The influence of the combined addition of cellulose fibers (FC) and microcrystalline celluloses (MCC) on the fresh properties and hydration kinetics of cementitious composites was investigated. For this purpose, sixteen different formulations of FC-MCC celluloses in the cement matrix were analyzed, in which various cellulose fibers were 0.5%, 1.0%, and 1.5% and microcrystalline cellulose in 0.4%, 0.6% and 0.8% about the cement mass. The cementitious composites with the addition of FC-MCC celluloses were characterized in terms of rheological behavior, which was determined through the Squeeze flow method, fluidity through the mini-slump test, and hydration kinetics determined through the temporal evolution of the temperature of the mixtures. The initial hydration tests showed that the maximum addition of MCC (0.8%) used in this work reduced the maximum temperature of the cementitious composites, as well as the combination of FCs with MCC 0.8. Cellulose fibers took a longer time to reach the maximum temperature. The combined contents of FC 1.0-MCC 0.4 and FC 0.5-MCC 0.6 promoted an increase in the maximum temperature, which could indicate a dispersive effect of the cellulose particles with the cementitious system. The results of the compression flow showed that the studied samples presented a flow with very low loads and extended for a large part of the curve. Te increase in the amount of cellulose fiber alters the main phenomena related to flow: with a high cellulose content (FC 1.5%) there is an increase in friction between the particles, leading to the conclusion that the amount of cellulose fibers in the cementitious system influences on the rheological behavior and the occurrence of phase separation.

Resumo Foi investigado a influência da adição combinada de fibras de celulose (FC) e microceluloses cristalinas (MCC) nas propriedades no estado fresco e cinética de hidratação dos compósitos cimentícios. Para isso, foram analisadas dezesseis diferentes formulações de celuloses FC-MCC na matriz cimentícia, no qual foram variadas fibras de celulose em 0.5%, 1.0% e 1.5% e microceluloses cristalinas em 0.4%, 0.6% e 0.8% em relação a massa do cimento. Os compósitos cimentícios com adição das celuloses FC-MCC foram caracterizados em termos de comportamento reológico, no qual foi determinado por meio do método Squeeze flow, de fluidez através do ensaio de mini-slump e de cinética de hidratação determinada por meio da evolução temporal da temperatura das misturas. Os testes de hidratação inicial mostraram que a adição máxima de MCC (0.8%) empregada nesse trabalho reduziu a temperatura máxima dos compósitos cimentícios, assim como a combinação das FC’s com a MCC 0.8. As fibras de celulose levaram um tempo maior para atingir a temperatura máxima. Os teores combinados de FC 1.0-MCC 0.4 e FC 0.5-MCC 0.6 promoveram um aumento da temperatura máxima podendo indicar um efeito dispersivo das partículas de celulose com o sistema cimentício. Os resultados do fluxo de compressão mostraram que as amostras estudadas apresentaram um fluxo com cargas muito baixas e se estendendo por grande parte da curva. O aumento da quantidade de fibra de celulose altera os principais fenômenos relacionados ao fluxo: com alto teor de celulose (FC 1.5%) há um aumento do atrito entre as partículas, podendo concluir que a quantidade de fibras de celulose no sistema cimentício influencia no comportamento reológico e na ocorrência de separação de fases.
