Seeking a viable alternative to fossil fuels as the primary energy source, bioethanol has emerged as a promising second-generation fuel derived from lignocellulosic biomass. With Brazil ranking pineapple as the third most produced fruit in temporary crops, this study aims to assess the impact of chemical pretreatment techniques, specifically organosolv and diluted acid, on the residual biomass of Pérola pineapple peel to enhance bioethanol production. Employing an experimental design that incorporates temperature, reaction time, and varying concentrations of organic solvent, the study examines their effects on the susceptibility of the substrate to saccharification for future bioethanol generation. Factors such as alphacellulose, hemicellulose, and lignin were evaluated in triplicate and subjected to statistical analysis using the Tukey test with a confidence level of 95%. Upon application of the pretreatment methods, it was observed that the organosolv solvent approach (utilizing water and ethanol) with sulfuric acid exhibited superior sugar conversion, yielding the highest concentration of xylose at 9.13 g L-1. Additionally, the pretreated biomass contained 1.38 g L 1 of cellobiose, 3.11 g L-1 of arabinose, and 3.76 g L-1 of glucose. This technique demonstrates promising potential for obtaining fermentable sugars crucial for bioethanol production. source secondgeneration second generation crops techniques production temperature time alphacellulose hemicellulose 95 95% methods utilizing ethanol conversion 913 9 13 9.1 L1.

RESUMO Regiões com climas semiáridos apresentam condições ambientais que resultam em estresses abióticos às plantas. A maior área de produção de melão (Cucumis melo L.) do Brasil, o Estado do Rio Grande do Norte, possui essas características climáticas. O uso de bioestimulantes nesses sistemas de produção pode mitigar os efeitos dos estresses abióticos e aumentar a produtividade e a qualidade dos frutos. O objetivo neste estudo foi avaliar as características fisiológicas e de produção do meloeiro, sob aplicação de bioestimulantes. Os bioestimulantes Acadian®, Folicist® e Nov@® foram aplicados e comparados ao tratamento controle (sem bioestimulantes), em melões ‘Goldex’ e ‘McLaren’. Nov@® proporcionou maior assimilação de CO2, transpiração e condutância estomática, assim como ascorbato peroxidase em ‘Goldex’ e ‘McLaren’. Maior catalase foi obtida pela aplicação de Nov@®, enquanto que o uso de Folicist® resultou em maior teor de malondialdeído. A cultivar McLaren apresentou o melhor desempenho fisiológico e bioquímico e a ‘Goldex’ o melhor rendimento. Folicist® promove adaptações fisiológicas aos estresses sem prejudicar a atividade fotossintética. Os bioestimulantes aumentaram a produtividade e o número de frutos por planta e promoveram adaptações fisiológicas às condições semiáridas. plantas Cucumis L.

ABSTRACT Regions with semi-arid climates have environmental conditions that result in abiotic stress to plants. The largest melon (Cucumis melo L.) production area in Brazil, the state of Rio Grande do Norte, has these climatic characteristics. Use of biostimulants in these production systems can mitigate effects of abiotic stress and increase yield and fruit quality. The objective in this study was to evaluate the physiological and production characteristics of melon, under the application of biostimulants. The biostimulants Acadian®, Folicist® and Nov@® were applied and compared to the control treatment (no biostimulants), in ‘Goldex’ and ‘McLaren’ melons. Nov@® led to higher CO2 assimilation, transpiration and stomatal conductance, as well as ascorbate peroxidase, in ‘Goldex’ and ‘McLaren’. Greater catalase was obtained with the application of Nov@®, while the use of Folicist® resulted in higher malondialdehyde content. The cultivar ‘McLaren’ exhibited the best physiological and biochemical performance, and ‘Goldex’ the best yield. Folicist® promotes physiological adaptations to stress without impairing photosynthetic activity. The biostimulants increased yield and number of fruits per plant and promoted physiological adaptations to semi-arid conditions. semiarid semi arid plants Cucumis L.

ABSTRACT Optic neuritis is an important cause of unilateral and acute visual loss in young adults, but other differential diagnoses should be considered, especially when the disease has an atypical presentation. This report presents the case of a young woman with reduced visual acuity in her right eye, associated with optic disc edema and a relative afferent pupillary defect, that was initially misdiagnosed as optic neuritis and subsequently found to have paracentral acute middle maculopathy, possibly secondary to subtle impending central retinal vein occlusion. This case emphasizes the need to remember that retinal vascular diseases can occasionally mimic optic neuritis. Detailed anamnesis and ophthalmic examination can avoid unnecessary interventions. adults considered presentation eye defect maculopathy occlusion interventions

RESUMO Objetivo: Avaliar a validade preditiva e o ponto de corte da frequência cardíaca e da pressão arterial nas alterações da variabilidade da frequência cardíaca (VFC) em crianças com e sem obesidade. Métodos: Foram incluídas 125 crianças neste estudo, sendo 41 com peso normal e 84 com obesidade. Antropometria, pressão arterial, frequência cardíaca e VFC foram medidas por meio de balança eletrônica e estadiômetro, esfigmomanômetro e monitor de VFC. Além disso, a curva característica de operação do receptor (ROC) foi obtida pela análise estatística dos dados. Resultados: A frequência cardíaca mostrou-se um bom preditor de alterações no parâmetro de raiz quadrada da média do quadrado das diferenças entre os intervalos NN consecutivos (RMSSD) em escolares de ambos os sexos para o grupo de peso normal (ROC 0,89; IC95% 0,77–1,00) e obesidade (ROC 0,90; IC95% 0,83–0,97). Além disso, o ponto de corte da frequência cardíaca para alterações no parâmetro RMSSD para meninos com peso normal foi de 93 bpm (sensibilidade 100,00% e especificidade 87,50%), e para meninos com obesidade, o ponto de corte estabelecido foi de 91 bpm (sensibilidade 94,74% e especificidade 63,64%). A frequência cardíaca também se mostrou um bom preditor considerando os índices da relação baixa frequência/alta frequência (LF/HF) e razão desvio padrão de intervalos NN contínuos de longo prazo/desvio padrão da variabilidade instantânea de intervalos NN contínuos na relação gráfica de Poincaré (SD2/SD1). As pressões arteriais sistólicas e diastólicas foram bons preditores em estratificações mais específicas e, portanto, podem ser utilizadas em alguns casos. Conclusões: A validade preditiva da frequência cardíaca mostrou-se em bom nível, com alta sensibilidade e especificidade aceitável para os pontos de corte, conforme as diferentes análises estratificadas por sexo e estado nutricional. Desta forma, os profissionais de saúde poderão utilizar a frequência cardíaca para estimar o risco cardiovascular em crianças de diferentes sexos e estado nutricional.

ABSTRACT Objective: To evaluate the predictive validity and cut-off point of heart rate and blood pressure on heart rate variability (HRV) changes in children with and without obesity. Methods: This study included 125 children, of whom 41 were normal weight and 84 were obese. Anthropometry, blood pressure, heart rate, and HRV were measured using an electronic scale and stadiometer, a sphygmomanometer, and HRV monitor. In addition, the receiver operating characteristic (ROC) curve was obtained by statistical analysis of the data. Results: Heart rate proved to be a good predictor for changes in the square root of the mean of the square of the differences between consecutive NN intervals (RMSSD) parameter in students of both sexes for the normal-weight group (ROC 0.89; 95%CI 0.77–1.00) and obesity (ROC 0.90; 95%CI 0.83–0.97). In addition, the heart rate cut-off point for alterations in the RMSSD parameter for normal-weight boys was 93 bpm (sensitivity 100.00% and specificity 87.50%) and for boys with obesity, the established cut-off point was 91 bpm (sensitivity 94.74% and specificity 63.64%). Heart rate also proved to be a good predictor considering low-frequency/high-frequency ratio (LF/HF) and standard deviation of long-term continuous NN intervals /standard deviation of the instantaneous variability of continuous NN intervals in the Poincaré graph ratio (SD2/SD1). Systolic and diastolic blood pressures were good predictors in more specific stratifications and, therefore, can be used in some cases. Conclusions: The predictive validity of heart rate was shown to be at a good level, with high sensitivity and acceptable specificity for the cut-off points according to the different analyses stratified by gender and nutritional status. In this sense, health professionals will be able to use heart rate to estimate cardiovascular risk in children of different sexes and nutritional status.

RESUMO Objetivo: Relatar dois casos de pneumotórax bilateral espontâneo múltiplo sucessivo em crianças com envolvimento pulmonar maciço por histiocitose de células de Langerhans (HCL), alertando para a possibilidade desse diagnóstico diferencial para o pediatra geral. Ademais, casos publicados que descrevem pacientes pediátricos com manifestações pulmonares de HCL foram revisados na literatura. Descrição do caso: Caso 1: Paciente masculino, três anos, com episódio súbito pneumotórax espontâneo à direita, drenado cirurgicamente. Após dois meses, apresentou dois novos episódios de pneumotórax contralateral. Biópsia linfonodal pulmonar revelou diagnóstico de HCL. Foi submetido a cirurgia torácica assistida por vídeo (VATS) bilateral e minitoracotomia com pleurodese mecânica, além de tratamento quimioterápico, necessitando de internação prolongada. Caso 2: Menino, quatro anos, apresentando dispneia progressiva e sibilância por cinco meses. Biópsia pulmonar revelou HCL. Evoluiu com importante desconforto respiratório e pneumotórax direito, necessitando drenagem. Foi realizada pleurodese com nitrato de prata e diferentes esquemas de quimioterapia. Ambos os pacientes evoluíram bem após tratamentos quimioterápicos múltiplos, cirurgias e suporte intensivo. Comentários: A HCL é uma doença desafiadora. Sua manifestação clínica é variável, e o envolvimento pulmonar ocorre em cerca de 10–15% dos casos. Consideram-se o manejo cirúrgico especializado e o suporte multidisciplinar essenciais para o tratamento de pacientes com HCL pulmonar maciça. Ainda que raro, o envolvimento pulmonar maciço por HCL deve ser considerado em quadros de pneumotórax recorrentes em crianças.

ABSTRACT Objective: The objective of this study was to report two cases of successive multiple spontaneous bilateral pneumothorax in children with massive lung involvement due to Langerhans cell histiocytosis (LCH), emphasizing the possibility of this differential diagnosis for the general pediatrician. Additionally, published cases describing pediatric patients with pulmonary manifestations of LCH were reviewed in the literature. Case description: Case #1: A 3-year-old male patient with a sudden episode of spontaneous right-sided pneumothorax, surgically drained. After 2 months, he experienced two new episodes of contralateral pneumothorax. A pulmonary lymph node biopsy revealed the diagnosis of LCH. He underwent bilateral video-assisted thoracic surgery and mini-thoracotomy with mechanical pleurodesis, in addition to chemotherapy, requiring prolonged hospitalization. Case #2: A 4-year-old boy with progressive dyspnea and wheezing for 5 months. A pulmonary biopsy revealed LCH. He developed significant respiratory distress and right pneumothorax, requiring drainage. Silver nitrate pleurodesis and different chemotherapy regimens were performed. Both patients responded well to multiple chemotherapy treatments, surgeries, and intensive care support. Comments: LCH is a challenging disease. Its clinical manifestation is variable, and pulmonary involvement occurs in about 10–15% of cases. We consider specialized surgical management and multidisciplinary support essential for the treatment of patients with massive pulmonary LCH. Although rare, massive pulmonary involvement by LCH should be considered in cases of recurrent pneumothorax in children.

ABSTRACT Safflower is a crop with seeds containing high amounts of oleic and linoleic acids, which have applications in cosmetics, food, feed, and pharmaceutical industries. Safflower seeds are generally reported to undergo after-ripening and to have physiological dormancy. This study comprehensively analyzed the physical changes and the induction of dormancy and germinability in developing seeds to determine whether the safflower population is adequately developed during seed dispersal. From the 80th day after flowering (DAF), seeds were collected separately from plants on a weekly basis until 131 DAF, resulting in seven sampling dates. The changes in length, diameter, thickness, water content, and fresh and dry weight during seed development were measured. Simultaneously, the effects of dark and light, temperature, and gibberellic acid (GA3) (0, 50, and 100 µM) on seed germination, dormancy and germination characteristics of safflower seeds were investigated. The seeds ceased to increase in length, width and thickness, reaching a mature appearance at 131 DAF, with a dry mass per seed of 0.0443 g. The water content decreased between 117 and 124 DAF, indicating an obvious process of desiccation during the final stage of seed maturation. Germination capacity is acquired at 117 DAF, as evidenced by an increase in germination and a reduction in dormant seeds, particularly at low temperatures (10°C) and with GA3 supplementation. At 131 DAF, seeds exhibited 7.9 % water content, and there was an increase in seed germination and a decrease in seed dormancy status, regardless of GA3 supplementation and temperature. acids cosmetics food feed industries afterripening ripening dispersal th DAF , (DAF) 13 dates length diameter thickness measured Simultaneously light temperature GA (GA3 0, 0 (0 50 10 µM investigated 00443 0443 0.044 g 11 12 maturation 10°C 10C C (10°C 79 7 9 7. status (DAF 1 (GA ( 5 0044 044 0.04 004 04 0.0 00 0.

RESUMO: No estado do Amazonas cultiva-se, tradicionalmente, a laranjeira ‘Pêra’ sobre o limoeiro ‘Cravo’. O uso restrito de uma única combinação de copa-porta-enxerto tem deixado os pomares locais vulneráveis à condições adversas e a incidência de pragas e doenças, podendo interferir negativamente tanto na produtividade como na qualidade dos frutos e sustentabilidade citrícola do Estado. A ampliação do número de combinações-copas-porta-enxertos torna-se uma alternativa viável para superar tais problemas. Para atender a esta demanda dos produtores de citros foram avaliadas 30 combinações com 10 copas e três porta-enxertos no sexto e sétimo ano após o plantio das mudas no campo, no município de Rio Preto da Eva, AM. Nesse experimento foram avaliadas: a produtividade, o rendimento de suco, os sólidos solúveis, o pH, a acidez titulável, o ratio e o índice tecnológico. A copa ‘Pineapple’ com os porta-enxertos tangerineira ‘Sunki Tropical’ e ‘BRS Bravo’ podem ser alternativas produtivas em relação a tradicional combinação laranja ‘Pêra’ sob limoeiro ‘Cravo’ no Amazonas. A copa laranja ‘Lima’ com os porta-enxertos tangerineira ‘Sunki Tropical’, limoeiro ‘Cravo Santa Cruz’ e ‘BRS Bravo’ podem ser alternativas para o mercado in natura no estado. As combinações que apresentaram boa qualidade do fruto são as copas ‘Pêra’, ‘Salustiana’, ‘Valência Tuxpan’ e ‘Westin’ com o porta-enxerto ‘BRS Bravo’, e a copa ‘Pêra D6’ com o porta-enxerto limoeiro ‘Cravo Santa Cruz’. Estas combinações são alternativas para a diversificação dos pomares do estado do Amazonas. RESUMO cultivase, cultivase cultiva se, se cultiva-se tradicionalmente Pêra ‘Cravo.

ABSTRACT: In the state of Amazonas, the ‘Pêra’ orange scion is traditionally cultivated on ‘Rangpur’ lime tree. The restricted use of a single scion-rootstock combination has left local orchards vulnerable to adverse conditions and incidence of pests and diseases, which may negatively interfere with both productivity and fruit quality and the citrus activity sustainability in the state. The expansion of the number of scion-rootstock combinations becomes a viable alternative to overcome such problems. To meet this demand from citrus growers, 30 combinations with 10 scions and 3 rootstocks were evaluated in the sixth and seventh year after planting seedlings in the field in the municipality of Rio Preto da Eva, AM. In this experiment, productivity, juice yield, soluble solids, pH, titratable acidity, ratio and technological index were evaluated. ‘Pineapple’ scion with ‘Sunki Tropical’ and ‘BRS Bravo’ rootstocks can be productive alternatives in relation to traditional ‘Pêra’ orange scion under ‘Rangpur’ lime combination in the state of Amazonas. ‘Lima’ orange with ‘Sunki Tropical’ mandarin, ‘Rangpur lime SC’ and ‘BRS Bravo’ lime rootstocks can be alternatives for the fresh market in the state. Combinations that showed good fruit quality are ‘Pêra’, ‘Salustiana’, ‘Valência Tuxpan’ and ‘Westin’ scions with ‘BRS Bravo’ rootstock, and ‘Pêra D6’ scion with ‘Rangpur lime SC’ lemon rootstock. These combinations are alternatives for the diversification of orchards in the state of Amazonas.

Abstract Introduction One of the paths in the investigation of congenital sensorineural hearing loss (CSNHL) is to try to characterize its etiology through the inner ear evaluation using high resolution computer tomography (CT) scans. With minor malformation, it is not always possible for a simple visual inspection to recognize if the structure in the inner ear is normal or not. Objective To verify if measurements of the inner ear are predictive of sensorineural hearing loss (SNHL) and suggest cutoff points of size limits. Methods Retrospective cross-sectional study of inner ear CT scan measurements of 214 patients, 50 with congenital SNHL (CSNHL) and 164 acquired SNHL (ASNHL) (control group). Results In the CSNHL group, central bony island (CBI) were 0.48 mm smaller (p < 0.001), cochlear nerve aperture was (CNA) 0.10 mm smaller (p < 0.001), and cochlea height was (CH) 0.15 mm smaller (p < 0.001). Vestibular aqueduct (VA) and cochlea width (CW) were similar between groups (0.70 vs 0.72, p = 0.19, and 7.20 vs 7.15 p = 0.23). The predictive cutoff points for CSNHL were CBI = 3.6 mm, CAN = 1.4 mm, CH = 3.4 mm, CW = 7.0 mm, and VA = 0.9 mm. Conclusion Congenital sensorineural hearing loss determined a decrease in CBI, opening of the cochlear nerve (OCN), and CW.

ABSTRACT Purpose To evaluate the morphological and stereological parameters of the testicles in mice exposed to bisphenol S and/or high-fat diet-induced obesity. Material and Methods Forty adult male C57BL/6 mice were fed a standard diet (SC) or high-fat diet (HF) for a total of 12 weeks. The sample was randomly divided into 4 experimental groups with 10 mices as follows: a) SC - animals fed a standard diet; b) SC-B - animals fed a standard diet and administration of BPS (25 μg/kg of body mass/day) in drinking water; c) HF: animals fed a high-fat diet; d) HF-B - animals fed a high-fat diet and administration of BPS (25 μg/Kg of body mass/day) in drinking water. BPS administration lasted 12 weeks, following exposure to the SC and HF diets. BPS was diluted in absolute ethanol (0.1%) and added to drinking water (concentration of 25 μg/kg body weight/day). The animals were euthanized, and the testes were processed and stained with hematoxylin and eosin (H&E) for morphometric and stereological parameters, including density of seminiferous tubules per area, length density and total length of seminiferous tubules, height of the tunica albuginea and the diameter of the seminiferous tubules. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image Pro and Image J programs. Means were statistically compared using ANOVA and the Holm-Sidak post-test (p<0.05). Results The seminiferous tubule density per area reduced in all groups when compared with SC samples (p<0.001): HF (40%), SC-B 3(2%), and HF-B (36%). Length density was reduced significantly (p<0.001) in all groups when compared with SC group: HF (40%), SC-B (32%), and HF-B (36%). The seminiferous tubule total length was reduced (p<0.001) when compared to f HF (28%) and SC-B (26%) groups. The tubule diameter increased significantly (p<0.001) only when we compared the SC group with SC (54%) an SC-B (25%) groups and the tunica thickness increased significantly only in HF group (117%) when compared with SC-B (20%) and HF-B 31%. Conclusion Animals exposed to bisphenol S and/or high-fat diet-induced obesity presented important structural alterations in testicular morphology. andor highfat high fat dietinduced induced C57BL6 CBL C57BL 6 C BL C57BL/ (SC (HF 1 weeks follows b SCB B (2 μgkg μg kg mass/day massday mass day c d HFB μgKg Kg diets 0.1% 01 0 (0.1% concentration 2 weight/day. weightday weight/day . weight weight/day) euthanized H&E HE H E (H&E BX BX5 DP DP7 camera programs HolmSidak Holm Sidak posttest post test p<0.05. p005 p p<0.05 05 (p<0.05) p<0.001 p0001 001 40%, 40 40% , (40%) 32%, 32 3 2% 3(2%) 36%. 36 36% (36%) (p<0.001 32% (32%) 28% 28 (28% 26% 26 (26% 54% 54 (54% 25% (25% 117% 117 (117% 20% 20 (20% 31 31% morphology ( 0.1 (0.1 p00 p<0.0 (p<0.05 p<0.00 p000 00 (40% 3(2% (36% (p<0.00 (32% (28 (26 5 (54 11 (117 (20 0.

Resumo Fundamento: O fondaparinux é um anticoagulante eficaz e seguro usado no tratamento de síndromes coronarianas agudas (SCAs). No entanto, devido à baixa representatividade de indivíduos obesos em ensaios clínicos, os efeitos de se aplicar os resultados desse medicamento nesta população continuam incertos. Objetivos: Comparar o fondaparinux à enoxaparina no tratamento de obesos com SCA. Métodos: Este é um estudo do tipo coorte retrospectivo, incluindo indivíduos obesos (IMC ≥ 30 Kg/m2) internados com Infarto do Miocárdio sem Elevação do Segmento ST (IAMSSST) ou Angina Instável (AI) e tratados com fondaparinux ou enoxaparina entre 2010 e 2020. Os grupos que receberam fondaparinux e enoxaparina foram comparados quanto suas características clínicas e laboratoriais usando o teste do qui-quadrado e o teste de Mann-Whitney, conforme apropriado. A incidência dos desfechos primários (morte, reinfarto, acidente vascular cerebral, sangramento maior) foi comparada entre os grupos. Um p<0,05 foi considerado estatisticamente significativo em todas as análises. Resultados: Um total de 367 pacientes obesos com IAMSSST ou AI foi incluído, dos quais 258 usaram fondaparinux e 109 usaram enoxaparina. A idade média foi 64 ± 12 anos, 52,9% eram do sexo masculino. A prevalência e diabetes, hipertensão, dislipidemia, doença arterial coronariana prévia, acidente vascular cerebral prévio, e implementação de estratégia invasiva foi similar entre os grupos. A incidência do desfecho primário foi 4,7% no grupo fondaparinux e 5,5% no grupo enoxaparina (p = 0,729). Não houve diferença entre os grupos quando os componentes do desfecho primário foram analisados separadamente. Conclusão: Em uma amostra de pacientes obesos com IAMSSST ou AI, não houve diferença na ocorrência do desfecho composto (morte, acidente vascular cerebral, reinfarto, sangramento maior) entre os pacientes que utilizaram fondaparinux ou enoxaparina.

Abstract Background: Fondaparinux is an effective and safe anticoagulant in the treatment of acute coronary syndromes (ACS). However, due to the low representation of obese individuals in clinical trials, the effects of applying the results of this drug to this population remain uncertain. Objectives: To compare Fondaparinux to Enoxaparin in the treatment of obese patients with ACS. Methods: This is a retrospective cohort study, including obese individuals (BMI ≥ 30 Kg/m2) admitted with non-ST-segment elevation myocardial infarction (NSTEMI) or unstable angina (UA) and treated with Fondaparinux or Enoxaparin between 2010 and 2020. The Fondaparinux and Enoxaparin groups were compared for their clinical and laboratory characteristics using chi-square and Mann-Whitney tests, as appropriate. The incidence of primary outcomes (death, reinfarction, stroke, major bleeding) was compared between groups. P-value < 0.05 was considered significant for all analyses. Results: A total of 367 obese patients with NSTEMI or UA were included, of whom 258 used Fondaparinux and 109 used Enoxaparin. Mean age was 64 ± 12 years, and 52.9% were male. The prevalence of diabetes, hypertension, dyslipidemia, prior coronary artery disease, prior stroke, and implementation of invasive strategy was similar between groups. The incidence of the primary outcome was 4.7% in the Fondaparinux group and 5.5% in the Enoxaparin group (p = 0.729). There was no difference between groups when analyzing the components of the primary outcome separately. Conclusion: In a sample of obese patients with NSTEMI or UA, there was no difference in the occurrence of the composite outcome (death, stroke, reinfarction, major bleeding) between patients who used Fondaparinux or Enoxaparin.

ABSTRACT The reports of fish cell cultivation date back to the early 20th century, and since then, it has become a tool of great importance for different areas of ichthyology, such as immunology, toxicology, and biotechnology. The cell cultivation methodology can vary according to the species and cell type, requiring knowledge of the specificities and characteristics of the target cell for them to be efficiently cultured. In this review, we address the main characteristics of the in vitro culture of fish cells, presenting their purposes, uses, main parameters, and different characteristics necessary for the culture environment. Finally, we present the experiences in Brazil using cell culture techniques.

Abstract: Pt Es En

A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares. O diagnóstico requer detecção por métodos de imagem (Ecocardiograma ou Ressonância Magnética Cardíaca) de qualquer segmento da parede do ventrículo esquerdo com espessura > 15 mm, sem outra causa provável. A análise genética permite identificar mutações de genes codificantes de diferentes estruturas do sarcômero responsáveis pelo desenvolvimento da CMH em cerca de 60% dos casos, permitindo o rastreio de familiares e aconselhamento genético, como parte importante do manejo dos pacientes e familiares. Vários conceitos sobre a CMH foram recentemente revistos, incluindo sua prevalência de 1 em 250 indivíduos, não sendo, portanto, uma doença rara, mas subdiagnosticada. A vasta maioria dos pacientes é assintomática. Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI).

La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).

Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.

RESUMO As características climáticas comuns em regiões semiáridas podem causar estresse abiótico e ser um fator limitante ao cultivo agrícola. Nessas condições, o uso de elementos benéficos como o selênio (Se) é uma alternativa para mitigar os efeitos deletérios dos estresses abióticos e aumentar a produtividade. Portanto, esta pesquisa teve como objetivo avaliar o desempenho agronômico da cebola cultivada em região semiárida sob aplicação de Se. Foi conduzido um experimento de campo, delineado em blocos casualizados completos, onde foram testadas cinco doses de Se (0, 15, 30, 45 e 60 g ha-1), por aplicação foliar, em dois híbridos de cebola (Andrômeda e Rio das Antas). Foram analisadas variáveis de crescimento, nutricional e produtividade. O Se aumentou a altura e o acúmulo de massa seca em plantas de cebola, com máxima na dose 60 g ha-1 de Se, mesma dose em que foi obtida a maior produtividade comercial (78,15 t ha-1) e total (86,03 t ha-1) de bulbos em Rio das Antas, todavia, para Andrômeda, não ocorreu efeito do Se sobre a produtividade. As doses de Se também aumentaram o teor desse elemento nos bulbos. Apesar de aumentar a produtividade de bulbos apenas em Rio das Antas, recomenda-se a aplicação de 60 g ha-1 de Se em cebola devido aos efeitos no crescimento da planta e na biofortificação dos bulbos com Se. agrícola condições (Se Portanto campo completos 0, 0 (0 15 30 4 6 ha1, ha1 ha 1 , foliar Andrômeda Antas.

ABSTRACT The common climatic characteristics in semi-arid regions can cause abiotic stress and be a limiting factor for crops. Under these conditions, the use of beneficial elements such as selenium (Se) is an alternative to mitigate the harmful effects of abiotic stresses and increase yield. Therefore, this research aimed to evaluate the agronomic performance of onion grown in a semi-arid region under the application of Se. A field experiment was performed in a randomized block design, where five doses of Se (0, 15, 30, 45, and 60 g ha-1), by foliar application, were tested on two onion hybrids (Andrômeda and Rio das Antas). Growth, nutritional and yield variables were analyzed. Se increased the height and accumulation of dry mass in onion plants, with a maximum at the 60 g ha-1 dose of Se, the same dose at which the highest commercial (78.15 t ha-1) and total (86.03 t ha-1) bulb yields were obtained in Rio das Antas; however, for Andrômeda, there was no effect of Se on yield. Applied Se doses also increased the content of this element in the bulbs. Despite increasing bulb yields only in the Rio das Antas hybrid, 60 g ha-1 of Se is recommended for onions due to its effects on plant growth and the biofortification of bulbs with Se. semiarid semi arid crops conditions (Se Therefore design 0, 0 (0 15 30 45 6 ha1, ha1 ha 1 , Andrômeda Antas. .

Resumo O cisto dentígero pode ser classificado como cisto de desenvolvimento ou inflamatório, originando-se durante o processo de separação do folículo que fica aprisionado ao redor da coroa de um dente incluso. O objetivo do presente artigo é relatar um caso clínico de enucleação de cisto dentígero em corpo mandibular à esquerda associado ao primeiro molar inferior (36) incluso com envolvimento do nervo alveolar inferior através da técnica cirúrgica de janela óssea por meio da piezocirurgia. Paciente de 19 anos, sexo masculino, sem comorbidades, com lesão hipodensa, circunscrita, de aproximadamente 15,5 x 27,7 x 14,8 mm identificada em tomografia de feixe cónico. A técnica de janela óssea executada apresenta como vantagem o reposicionamento do segmento ósseo deslocado no transoperatório, favorecendo o processo de reparo, além do acesso direto à área contendo a lesão cística e o elemento incluso.

Abstract A dentigerous cyst can be classified as a developmental or inflammatory cyst. It originates during the process of separation from the follicle that becomes trapped around the crown of an impacted tooth. The purpose of this article is to report a clinical case of enucleation of a dentigerous cyst in the left mandibular body associated with the impacted lower first molar (tooth 36), with involvement of the inferior alveolar nerve, through the bone window surgical technique using piezosurgery. A 19-year-old male patient with no comorbidities presented with a well-defined hypodense lesion of approximately 15.51mm X 27.69mm X 14.79mm in diameter, as identified by cone-beam tomography. The bone window technique performed offers the advantage of repositioning the bone segment displaced during surgery, promoting the repair process, and providing direct access to the area containing the cystic lesion and the impacted tooth.
