Worldwide, millions of people suffer from neurological and psychiatric conditions, such as schizophrenia, depression, and neurodegenerative diseases. These conditions are often linked to hyperactivity of monoamine oxidase B (MAO-B) in the brain, and inhibiting this enzyme can reduce oxidative stress, stabilize neurotransmitter levels, and alleviate symptoms. In this context, a pharmacophoric model was created using PharmaGist with 31 hits extracted from BindingDB to enable a pharmacophoric-based search of potential MAO-B inhibitors in ZincPharmer’s chemical space, followed by the building of 10 conformers for each molecule in the software OMEGA, screening for structural and electrostatic similarity to safinamide using ROCS (Rapid overlay of chemical structures) and EON (Electrostatic similarity for lead-hopping), respectively. In addition, the molecular docking with Gold using the score function was performed to rank the ligands with the highest probabilities of affinity to MAO-B and then discriminate those with suitable physical chemical, pharmacokinetic, and toxicological features using the tools QikProp, SwissADME, and DEREK. Four potential ligands with selective MAO-B inhibitor properties were identified, which show promise as future therapeutic agents for MAO-B-related disorders.

Jaboticaba peel powder (JPP) is a residue that contains phenolic compounds, such as anthocyanins and gallic acid. An adsorbent-bioactive complex (ABC) was synthesized using an extract rich in compounds with antioxidant properties obtained from JPP immobilized on microcrystalline cellulose from sweet sorghum bagasse. In this work, the result of thermal degradation of anthocyanins from JPP and ABC, activation energy (Ea), half-life time (t1/2), decimal reduction time (D), temperature variation (Z), thermodynamic parameters (enthalpy (ΔH), Gibbs free energy (ΔG) and entropy (ΔS)) and degradation of antioxidant activities were investigated. Anthocyanin degradation of 35, 60 and 85% was observed for JPP and 10, 30 and 65% for ABC at temperatures of 90-130 °C. Ea of JPP and ABC were 110 and 91 kJ mol-1, respectively. ABC was able to increase from 143-690% the half-life time when compared to JPP. The Z parameter indicated that a greater temperature variation is necessary to degrade ABC anthocyanins (31 °C) when compared to JPP (25 °C). The thermodynamic parameters showed that the energy needed to be broken down to reach the transition state is higher for JPP than ABC, in addition ABC is closer to its thermodynamic equilibrium state. Thus, ABC can be used as an additive in pharmaceutical, cosmetics and food industries, maintaining bioactive and antioxidant properties.

Phosphate species can affect aquatic ecosystems, as excess of this nutrient can cause eutrophication, generating environmental impacts. Lamellar double hydroxides have shown promise in removing phosphate at low concentrations (10-50 mg L 1). In this context, lamellar double hydroxides were synthesized interspersed with nitrates and humic substances, searching for a new product that favors phosphorus adsorption. X-ray diffraction showed the presence of characteristic peaks of lamellar double hydroxides and thermogravimetric analysis showed the decomposition behavior of lamellar structure. The adsorption capacity occurred quickly (< 30 min), being more efficient for lamellar double hydroxides with NO3. The maximum adsorption capacity showed results of 35.03 and 44.20 mg g 1 for lamellar double hydroxides with humic substances and lamellar double hydroxides with NO3, respectively. The complexation capacity showed that pH directly influences complexation, being greater for lamellar double hydroxides with humic substances at pH 6.5. Thus, nanostructured materials with humic substances are promising for use in contaminant remediation and adsorption can be a fast and efficient technique for use in soil and water. ecosystems eutrophication impacts 1050 10 50 (10-5 1. . 1) context Xray X ray structure < ( 3 min, min , min) NO3 NO 3503 35 03 35.0 4420 44 20 44.2 respectively 65 6 5 6.5 Thus water 105 (10- 350 0 35. 442 4 2 44. 6.

The essential oil extracted from Anemia tomentosa (EOAT) has shown larvicidal potential against Aedes aegypti, based on methods in vitro and in silico. Chromatographic and spectrometric techniques (gas chromatography-mass spectrometry (CG-MS), gas chromatography-flame ionization detector (GC-FID)), as well as mono and bidimensional nuclear magnetic resonance spectroscopy (NMR) were used to assess 10 essential oil components. Chemical composition of essential oil comprised 87.51% sesquiterpenes, with emphasis on presilphiperfolan-1-ol (42.13%) and silphiperfol-5-ene (19.47%). Larvicidal assay conducted in vitro with EOAT has evidenced potential cytotoxic activity up to 48 h exposure to it; mortality rate observed for A. aegypti larvae exposed to essential oil reached 100%. Study conducted in silico with chemical compounds deriving from the herein investigated plant species has evidenced its potential to inhibit acetylcholinesterase in A. aegypti. Activity of triquinane sesquiterpenes ranging from -6.8 to -8.2 kcal mol-1 stood out in comparison to that of temephos (-7.5 kcal mol-1). Chemical compounds identified in the investigated essential oil presented low human and environmental toxicity, as observed in absorption, distribution, metabolism and excretion, and toxicity (ADMETox) predictions.

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stands for being the most serious epidemic (so far) of the 21st century. However, only a few computational studies have investigated the molecular mechanisms underlying the neutralization of the spike protein by antibodies of different classes. Hence, bioinformatic methods were employed to unravel the factors contributing to the remarkable neutralization capacity exhibited by specific antibodies. Initially, crystallographic structures of IgA monomeric / dimeric, IgG, and IgM antibodies binding with the receptor-binding domain region of the SARS-CoV-2 spike protein were retrieved. Subsequently, rigid molecular docking and molecular dynamic simulations were performed over 100 ns with explicit water solvation. Lastly, an energy decomposition was conducted to estimate the binding affinity using the last frames from molecular dynamics. The results revealed a higher binding affinity for both monomeric and dimeric forms of IgA antibodies against the spike protein. Additionally, a greater number of hydrogen bonds were observed during their interaction with the spike protein, as well as greater structural instability along the time and especially a more thermodynamically favorable interaction affinity. In this way, the research contributes a small piece to the complex puzzle of understanding the humoral immune response induced by the SARS-CoV-2 virus.

ABSTRACT The application of wood ash in agriculture emerges as a promising technique to enhance agricultural productivity. Its chemical composition can improve soil attributes, acting as a fertilizer, corrective agent, and assisting in water retention. However, studies recommend controlled adoption to avoid adverse impacts. The objective of this article is to evaluate the potential of wood ash as a fertilization strategy in peanut cultivation, with an emphasis on optimizing plant productivity and reducing water deficit. The experiment was carried out in a greenhouse in 5 dm3 pots; the experimental design applied was randomized blocks, forming a 5x5 factorial scheme, corresponding to five doses of wood ash (0; 8; 16; 24 and 32 g dm-3) and five levels of water availability (25; 50; 75; 100 and 125% of field capacity), with four repetitions. The cultivar used was IAC OL-3. The data were subjected to the normality test to check whether they followed the normal distribution and, subsequently, subjected to analysis of variance and, when significant, subjected to regression analysis, at a 5% probability of error. Wood ash, rich in nutrients, proved to be a viable alternative source of nutrients. Doses between 18.4 and 22.8 g dm-3 of wood ash led to the most satisfactory results. The water availability that responded best ranged from 96 to 111.3%. Wood ash, at doses of 22.8 and 19.64 g dm-3, contributed to water consumption and soil water efficiency. attributes fertilizer agent retention However impacts cultivation deficit dm pots blocks x 5x scheme 0 (0 8 16 2 3 25 (25 50 75 10 125 capacity, capacity , capacity) repetitions OL3.

ABSTRACT BACKGROUND: The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is commonly used to assess the functional status of athletes with conditions affecting the shoulder and elbow. However, a Brazilian Portuguese version of the KJOC questionnaire is currently unavailable. OBJECTIVES: This study aimed to develop a Brazilian Portuguese version of the KJOC questionnaire. DESIGN AND SETTING: This translation and cultural adaptation study was conducted at the Federal University of Paraíba, Brazil. METHODS: The procedures adopted in this study followed guidelines recommending translation by two independent translators, synthesis of the translations, back-translation performed by two native English-speaking translators, analysis by an expert committee, and pre-testing. The Portuguese version was tested with 32 athletes to assess their understanding of the assessment tool. Items were deemed adequate if they were understood by at least 90% of the athletes. RESULTS: The terms and expressions of some original items were modified to achieve better comprehensibility in the Brazilian context. No further modifications were necessary after the pre-test; all terms were comprehensible to over 90% of athletes. CONCLUSION: The translation and cultural adaptation of the KJOC questionnaire into Portuguese were completed, resulting in a Brazilian version of the scale. Further studies are needed to evaluate the reliability and validity of this scale.

Abstract Objective To analyze risk factors (maternal, obstetric and demographic) associated with congenital syphilis and the clinical characteristics of the newborns. Method A cross-sectional study carried out in ten public maternity hospitals in Fortaleza, Ceará, Brazil that included cases of live births reported with congenital syphilis in 2015. Results 469 cases were analyzed; 199 (42.4 %) showed some sign or symptom suggestive of congenital syphilis; of these, 65 (32.7 %) were preterm, 87 (43.7 %) had low birth weight, 116 (58.3 %) had jaundice that required phototherapy, 13 (6.5 %) had hepatomegaly, 10 (5 %) had skin lesions, eight (4.0 %) had splenomegaly and one (0.5 %) had limb pseudoparalysis. Records of other clinical changes were identified in 36 (7.7 %) children. Children whose mothers were not treated or who received a drug other than penicillin and those whose mothers had a VDRL titer ≥ 1:16 at birth were 3.7 and 3.2 times more likely to be born with signs of congenital syphilis (p < 0.001- 95 % CI 2.41-5.58; p < 0.001 - 95 % CI 2.41-5.58) respectively. Conclusions The findings of this study draw attention to the importance of improving the quality of prenatal care and the development of studies aimed at finding alternative drugs for the treatment of syphilis in pregnant women and the prevention of congenital syphilis. maternal, maternal (maternal demographic newborns crosssectional cross sectional Fortaleza Ceará 2015 46 analyzed 19 42.4 424 42 4 (42. these 6 32.7 327 32 7 (32. preterm 8 43.7 437 43 (43. weight 11 58.3 583 58 3 (58. phototherapy 1 6.5 5 (6. hepatomegaly ( lesions 4.0 40 0 (4. 0.5 05 (0. pseudoparalysis 7.7 77 (7. children 16 1:1 37 3. 2 0001 001 9 2.415.58 241558 2.41 5.58 41 2.41-5.58 0.00 respectively 201 42.

RESUMO Introdução: Doenças pulmonares são comuns em pacientes com doença renal em estágio terminal (DRET), dificultando o diagnóstico diferencial com COVID-19. Este estudo descreve achados de tomografia computadorizada de tórax (TC) em pacientes com DRET em terapia renal substitutiva (TRS) hospitalizados com suspeita de COVID-19. Métodos: Indivíduos maiores de 18 anos com DRET, encaminhados ao pronto-socorro com suspeita de COVID-19 foram incluídos. Dados clínicos e epidemiológicos foram extraídos de registros eletrônicos de saúde. A TC foi classificada como típica, indeterminada, atípica, negativa. Comparamos achados tomográficos de pacientes com COVID-19 positivos e negativos. Resultados: Recrutamos 109 pacientes (62,3% COVID-19-positivos) entre março e dezembro de 2020, idade média de 60 ± 12,5 anos, 43% mulheres. A etiologia mais comum da DRET foi diabetes. Tempo médio em diálise foi 36 meses, intervalo interquartil = 12–84. A lesão pulmonar mais comum foi opacidades em vidro fosco. O padrão típico de TC foi mais comum em pacientes com COVID-19 (40 (61%) vs. 0 (0%) em pacientes sem COVID-19, p < 0,001). Sensibilidade 60,61% (40/66), especificidade 100% (40/40). Valores preditivos positivos e negativos foram 100% e 62,3%, respectivamente. Padrão atípico de TC foi mais frequente em pacientes COVID-19-negativos (9 (14%) vs. 24 (56%) em COVID-19-positivos, p < 0,001), enquanto padrão indeterminado foi semelhante em ambos os grupos (13 (20%) vs. 6 (14%), p = 0,606), e padrão negativo foi mais comum em pacientes COVID-19-negativos (4 (6%) vs. 12 (28%), p = 0,002). Conclusões: Em pacientes com DRET em TRS hospitalizados, um padrão atípico de TC de tórax não pode excluir adequadamente o diagnóstico de COVID-19. Introdução , (DRET) COVID19.

ABSTRACT Introduction: Lung diseases are common in patients with end stage kidney disease (ESKD), making differential diagnosis with COVID-19 a challenge. This study describes pulmonary chest tomography (CT) findings in hospitalized ESKD patients on renal replacement therapy (RRT) with clinical suspicion of COVID-19. Methods: ESKD individuals referred to emergency department older than 18 years with clinical suspicion of COVID-19 were recruited. Epidemiological baseline clinical information was extracted from electronic health records. Pulmonary CT was classified as typical, indeterminate, atypical or negative. We then compared the CT findings of positive and negative COVID-19 patients. Results: We recruited 109 patients (62.3% COVID-19-positive) between March and December 2020, mean age 60 ± 12.5 years, 43% female. The most common etiology of ESKD was diabetes. Median time on dialysis was 36 months, interquartile range = 12–84. The most common pulmonary lesion on CT was ground glass opacities. Typical CT pattern was more common in COVID-19 patients (40 (61%) vs 0 (0%) in non-COVID-19 patients, p < 0.001). Sensitivity was 60.61% (40/66) and specificity was 100% (40/40). Positive predictive value and negative predictive value were 100% and 62.3%, respectively. Atypical CT pattern was more frequent in COVID-19-negative patients (9 (14%) vs 24 (56%) in COVID-19-positive, p < 0.001), while the indeterminate pattern was similar in both groups (13 (20%) vs 6 (14%), p = 0.606), and negative pattern was more common in COVID-19-negative patients (4 (6%) vs 12 (28%), p = 0.002). Conclusions: In hospitalized ESKD patients on RRT, atypical chest CT pattern cannot adequately rule out the diagnosis of COVID-19.

RESUMO A doença renal crônica (DRC) representa um dos principais problemas de saúde pública da atualidade. A dosagem da creatinina sérica e a estimativa da taxa de filtração glomerular (TFG) são as principais ferramentas para avaliação da função renal. Para a estimativa da TFG, existem diversas equações, sendo a mais recomendada a CKD-EPI (Chronic Kidney Disease – Epidemiology). Existem ainda algumas controvérsias com relação à dosagem da creatinina sérica e da estimativa da TFG, uma vez que vários fatores podem interferir nesse processo. Uma importante mudança recente foi a retirada da correção por raça das equações para estimativa da TFG, que superestimavam a função renal, e consequentemente retardavam a implementação de tratamentos como diálise e transplante renal. Neste documento de consenso da Sociedade Brasileira de Nefrologia e Sociedade Brasileira de Patologia Clínica e Medicina Laboratorial são revisados os principais conceitos relacionados à avaliação da função renal, possíveis controvérsias existentes e recomendações para a estimativa da TFG na prática clínica.

ABSTRACT Chronic kidney disease (CKD) represents one of today’s main public health problems. Serum creatinine measurement and estimation of the glomerular filtration rate (GFR) are the main tools for evaluating renal function. There are several equations to estimate GFR, and CKD-EPI equation (Chronic Kidney Disease – Epidemiology) is the most recommended one. There are still some controversies regarding serum creatinine measurement and GFR estimation, since several factors can interfere in this process. An important recent change was the removal of the correction for race from the equations for estimating GFR, which overestimated kidney function, and consequently delayed the implementation of treatments such as dialysis and kidney transplantation. In this consensus document from the Brazilian Societies of Nephrology and Clinical Pathology and Laboratory Medicine, the main concepts related to the assessment of renal function are reviewed, as well as possible existing controversies and recommendations for estimating GFR in clinical practice.

RESUMO A taxa líquida de matrícula na pré-escola aumentou de 3,7% para 78,9% entre 1970 e 2018. Este artigo analisa o processo de universalização da pré-escola no Brasil ocorrido nos últimos 50 anos, documentando a evolução do acesso e discutindo de forma analítica a influência de fatores sociodemográficos e institucionais comumente atribuídos à expansão da pré-escola no Brasil. Fatores como oferta de trabalho feminina, investimento público e demografia, embora tenham sua importância, não foram decisivos para a expansão da pré-escola tal que a expansão observada no período parece fruto de políticas não coordenadas e não planejadas implementadas no período. préescola pré escola 37 3 7 3,7 789 78 9 78,9 197 2018 5 anos feminina demografia importância 3, 78, 19 201 1 20 2

ABSTRACT The school attendance of 4-5 years-old children raised from 3.7% to 78.9% between 1970 and 2018 in Brazil. This paper analyses the preschool expansion process in Brazil in the last 50 years, documenting the preschool attendance and discussing how sociodemographic and institutional factors usually associated with the expansion are related to the process. The paper shows that female labor force participation, public investments, and demographic factors were to some extent important but not crucial to the expansion of preschool attendance in Brazil. Furthermore, the observed expansion seems to be a result of uncoordinated and unplanned policies implemented in the period. 45 4 5 4- yearsold years old 37 3 7 3.7 789 78 9 78.9 197 201 participation investments Furthermore period 3. 78. 19 20 1 2

Abstract Objectives: To analyze bone mineral content (BMC) and area bone mineral density (aBMD) accrual in adolescent male footballers who started their first football season. Methods: 17 athletes (14.8 ± 0.4 years) were monitored across 15 weeks of football training. Participants were evaluated for somatic maturation (HPHV), BMC, and aBMD at three time points: before (M1) and after (M2) a preparatory phase, and at the end of the competitive phase (M3). BMC and aBMD were measured using DXA scans. Participants were divided into groups according to maturation status (circa-PHV and post-PHV), and the amount of accumulated training load (median split). Results: A significant effect (12.1 g/week, standard error (SE) = 2.6 g/week) was observed for lower limbs BMC across the three time points. There were no significant effects of time for upper limbs BMC. There was a significant effect of time for total body aBMD (0.007, SE = 0.003 g/cm2/week) across the three time points. Adolescents at post-PHV had a significant 245.6 g (SE = 56.1 g) higher BMC compared to adolescents at circa-PHV. No significant effects were observed for the accumulated training load. Conclusion: Systematic football training, even during the growth spurt, has a positive impact on adolescent bone markers despite the accumulated training load and maturation.

Abstract Introduction: Renal osteodystrophy (ROD) refers to a group of bone morphological patterns that derive from distinct pathophysiological mechanisms. Whether the ROD subtypes influence long-term outcomes is unknown. Our objective was to explore the relationship between ROD and clinical outcomes. Methods: This study is a subanalysis of the Brazilian Registry of Bone Biopsies (REBRABO). Samples from individual patients were classified as having osteitis fibrosa (OF), mixed uremic osteodystrophy (MUO), adynamic bone disease (ABD), osteomalacia (OM), normal/minor alterations, and according to turnover/mineralization/volume (TMV) system. Patients were followed for 3.4 yrs. Clinical outcomes were: bone fractures, hospitalization, major adverse cardiovascular events (MACE), and death. Results: We enrolled 275 participants, of which 248 (90%) were on dialysis. At follow-up, 28 bone fractures, 97 hospitalizations, 44 MACE, and 70 deaths were recorded. ROD subtypes were not related to outcomes. Conclusion: The incidence of clinical outcomes did not differ between the types of ROD.

RESUMO Introdução: O glifosato é o herbicida mais utilizado no mundo e no Brasil. Atualmente, há uma preocupação crescente com os efeitos do glifosato na saúde humana. O Instituto Brasileiro de Defesa do Consumidor apresentou dados sobre a presença de glifosato em alguns dos produtos ultraprocessados mais consumidos no Brasil. Atualmente, as regulamentações sobre o limite máximo desses resíduos em alimentos ultraprocessados ainda não foram estabelecidas pela Vigilância Sanitária Nacional, e o consumo de alimentos ultraprocessados está independentemente associado a um risco maior de doença renal crônica incidente. Métodos: Como uma dieta desbalanceada pode interferir na função renal, este estudo tem como objetivo investigar o efeito da ingestão diária de 5 mg/kg pc de glifosato em conjunto com uma dieta equilibrada e o possível impacto na função renal em ratos. Foram avaliados função renal, peso dos rins, marcadores de lesão renal e estresse oxidativo. Resultados: Houve redução no peso dos rins. As principais alterações histopatológicas nos tecidos renais foram vacuolização no estágio inicial e regulação positiva do marcador de lesão renal KIM-1. A lesão renal está associada à produção aumentada de espécies reativas de oxigênio nas mitocôndrias. Conclusão: Esse estudo mostrou alterações nos rins de ratos expostos a uma dieta balanceada com glifosato, sugerindo um risco potencial ao rim humano. Presumivelmente, alimentos ultraprocessados que contenham glifosato podem potencializar esse risco. A relevância desses resultados está no fato de chamar a atenção para a necessidade de regulamentar a concentração de glifosato em alimentos ultraprocessados no futuro.

Abstract Introduction: Glyphosate is the most widely used herbicide worldwide and in Brazil. There is currently increasing concern about the effects of glyphosate on human health. The Brazilian Institute for Consumer Protection showed data on the presence of glyphosate in some of Brazil’s most consumed ultra-processed products. Currently, regulations on the upper limit for these residues in ultra-processed foods have yet to be established by the National Health Surveillance, and ultra-processed food consumption is independently associated with an increased risk of incident chronic kidney disease. Methods: Since an unbalanced diet can interfere with kidney function, this study aims to investigate the effect of daily intake of 5 mg/kg bw glyphosate in conjunction with a balanced diet and the possible impact on renal function in rats. Kidney function, kidney weight, markers of renal injury, and oxidative stress were evaluated. Results: There was a decrease in kidney weight. The main histopathological alterations in renal tissues were vacuolation in the initial stage and upregulation of the kidney injury marker KIM-1. Renal injury is associated with increased production of reactive oxygen species in mitochondria. Conclusion: This study showed changes in the kidney of rats exposed to a balanced diet with glyphosate, suggesting a potential risk to human kidney. Presumably, ultra-processed food that contain glyphosate can potentiate this risk. The relevance of these results lies in drawing attention to the need to regulate glyphosate concentration in ultra-processed foods in the future.

RESUMO Em ambientes irrigados, o crescimento vegetativo da cana-de-açúcar e o consumo de carboidratos durante a maturação requerem o manejo de maturadores para aumentar a produtividade da cultura. A combinação de maturadores, com nutrientes e bioestimulantes como os aminoácidos, pode promover respostas fisiológicas que favorecem a qualidade da matéria-prima e aumentam o teor de sacarose. Dessa forma, o estudo teve como objetivo avaliar a resposta agroindustrial da cultura de cana-de-açúcar fertirrigada aos agentes de maturação. Os tratamentos consistiram na aplicação de maturador químico (MQ), nutricional (MN), aplicação conjunta de MN+MQ e controle com quatro repetições. Os atributos agroindustriais (sólidos solúveis totais, sacarose aparente (AS), açúcares redutores (AR), açúcares totais recuperáveis (ATR), pureza, fibra, sacarose no colmo (SS) foram avaliados em 0 (antes da aplicação), 12, 19, 36 e 60 dias após aplicação (DAA). O tempo modificou os atributos tecnológicos da cana-de-açúcar sob aplicação de maturador. Os maiores valores de caldo AS e sólidos solúveis totais foram obtidos no MN+MQ em relação ao controle. Os tratamentos MN e MN+MQ apresentaram os maiores teores de ATR (150 kg Mg-1), aos 36 DAA. Além disso, o tratamento MN+MQ aumentou o teor de fibra, mas não comprometeu a qualidade da matéria-prima, e apresentou altos teores de SC e pureza, bem como baixos teores de AR. Os maturadores químicos e nutricionais foram eficientes em promover o amadurecimento da cana-de-açúcar em áreas sem secagem antes da colheita. A aplicação de MN no final do ciclo tem potencial para aumentar a produtividade de açúcar. irrigados canadeaçúcar cana açúcar aminoácidos matériaprima matéria prima forma MQ, MQ , (MQ) MN, (MN) MNMQ repetições AS, (AS) AR, AR (AR) ATR, (ATR) pureza fibra SS (SS aplicação, aplicação) 12 19 3 6 DAA .

ABSTRACT In irrigated fields, sugarcane’s vegetative growth and carbohydrate consumption during ripening require ripener management options to improve crop yield. The hypothesis is that ripeners, together with nutrients, biostimulants, and amino acids, improve physiological responses that favor the quality of the raw material and increase the sucrose content. Consequently, the study aimed to evaluate the agro-industrial response of a fertigated sugarcane crop to ripening agents. The treatments consisted of applying chemical ripener (CR), nutritional ripener (NR), and a joint application of NR+CR, besides control with four replicates. Agro-industrial attributes (total soluble solids, apparent sucrose (AS), reducing sugars (RS), total recoverable sugar (TRS), purity, fiber, sucrose in the stalk (SS) were evaluated at 0 (before application), 12, 19, 36, and 60 days after application (DAA). The time modified the technological attributes of sugarcane under ripener application. The highest apparent sucrose and total soluble solids values were obtained with NR+CR compared to the control. The NR and NR+CR treatments presented the highest TRS contents (150 kg Mg-1) at 36 DAA. Furthermore, the NR+CR treatment increased fiber content but did not compromise the quality of the raw material, and it showed high contents of SS and purity percentage, as well as low contents of RS. The chemical and nutritional ripeners efficiently promoted sugarcane ripening in areas without drying off before harvest. NR application at the end of the cycle can potentially increase sugar yield. fields sugarcanes s yield nutrients biostimulants acids Consequently agroindustrial agro industrial agents CR, CR , (CR) NR, (NR) NRCR replicates Agroindustrial Agro AS, AS (AS) RS, RS (RS) TRS, (TRS) (SS application, application) 12 19 6 DAA .
