ABSTRACT The attempt to face the limitations of wood-based materials, especially concerning the relationship with water, is still a considerable gap in research on this subject. The present work proposes the accomplishment of thermal treatment in fiberboard-type hardboard, using different temperatures and times, to evaluate the effect on the physical-mechanical properties. The parameters of the heat treatment were temperatures of 120 and 160 °C and times of 20 and 40 min. The hardboards were individually heat treated in a kiln. The characterization was performed from physical tests such as bulk density, moisture content, water absorption (2 and 24 h), thickness swelling (2 and 24 h); and mechanical properties of flexural strength. The treatment with a temperature of 160 °C for 40 min showed the lowest values of water absorption in 24 h (34%). Thickness swelling was lower compared to control, for all the treatments applied. Regarding flexural strength, the treatment that adopted the 160 °C for 20 min showed the highest MOR value (26.3 MPa). In general, the performance of heat treatments positively influenced the physical and mechanical properties of the hardboards, being an interesting alternative in the development of products for applications in internal environments.

Resumo O objetivo deste trabalho foi selecionar, simultaneamente, híbridos pré-comerciais de sorgo granífero com alta adaptabilidade e estabilidade da produção de grãos, por meio de modelagem mista, em 20 ambientes, por seis anos. O material vegetal avaliado consistia de 57 híbridos comerciais de sorgo granífero. Em todos os experimentos, os híbridos foram arranjados em delineamento fatorial triplo; alguns experimentos utilizaram um fatorial 6x6, e outros, um fatorial 5x5. Os parâmetros de adaptabilidade e estabilidade foram obtidos com base na predição por média harmônica da performance relativa dos valores genéticos (MHPRVG). Os modelos mistos mostraram-se adequados para analisar a interação genótipo x ambiente (GxE) e os estudos de adaptabilidade e estabilidade genotípica do sorgo granífero. Os híbridos que se destacam, considerando-se todos os ambientes, são 1G282, A9904, 50A50, A9902 e XB6022. O híbrido A9904 destaca-se em ambientes favoráveis, com rendimento de grãos acima da média. Apenas 1G282 está entre os cinco melhores híbridos para cada grupo de ambientes e é o melhor híbrido de sorgo granífero quanto ao rendimento, à adaptabilidade e à estabilidade. Os valores genotípicos preditos com base em médias genotípicas podem ser usados em relação aos ambientes com o mesmo padrão de interação GxE por estarem livres da interação GxE.

Abstract The objective of this work was to simultaneously select pre-commercial grain sorghum hybrids with high adaptability and yield stability, through mixed modeling, in 20 environments, during six years. The evaluated plant material consisted of 57 commercial grain sorghum hybrids. In all experiments, hybrids were arranged in a triple lattice design; some experiments used a 6x6 lattice, and others, a 5x5 lattice. Adaptability and stability parameters were obtained based on the prediction by harmonic mean of the relative performance of genotypic values (HMRPGV). The mixed models proved to be adequate to analyze the genotype x environment (GxE) interaction and the genotypic adaptability and stability studies on grain sorghum. The hybrids that stand out, considering all environments are 1G282, A9904, 50A50, A9902, and XB6022. The A9904 hybrid stands out in favorable environments, with a grain yield above average. Only 1G282 is among the five best hybrids for each group of environments, and it is the best grain sorghum hybrid for yield performance, adaptability, and stability. The predicted genotypic values based on genotypic means can be used in the environments with the same GxE interaction pattern because they are free of the GxE interaction.

Resumen: En Es | Texto: En Es | PDF: En | PDF: Es

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

Resumen: En | Texto: En | PDF: En

ABSTRACT: Sorghum breeding programs are based predominantly on developing homozygous lines to produce single cross hybrids, frequently with relatively narrow genetic bases. The adoption of complementary strategies, such as genetic diversity study, enables a broader vision of the genetic structure of the breeding germplasm. The purpose of this study was to evaluate the genetic diversity of sorghum breeding lines using structure analysis, principal components (PC) and clustering analyses. A total of 160 sorghum lines were genotyped with 29,649 SNP markers generated by genotyping-by-sequencing (GBS). The PC and clustering analyses consistently divided the R (restorer) and B (maintainer) lines based on their pedigree, generating four groups. Thirty-two B and 21 R lines were used to generate 121 single-cross hybrids, whose performances were compared based on the diversity clustering of each parental line. The genetic divergence of B and R lines indicated a potential for increasing heterotic response in the development of hybrids. The genetic distance was correlated to heterosis, allowing for the use of markers to create heterotic groups in sorghum.

Resumen: En | Texto: En | PDF: En

Abstract In this study, we present two cases of cutaneous leishmaniasis in patients with end-stage renal disease, who were treated solely with intramuscular pentamidine. In such cases, treatment implies a fine line between therapeutic efficacy and toxicity. This is suggestive of a knowledge gap; however, findings indicate that this is still the fastest and safest alternative to the treatment with antimonials. Also, it can help avoid the side effects that occur upon using antimonials.

Resumen: En | Texto: En | PDF: En

ABSTRACT: Helicoverpa armigera (Hübner) regularly requires quick deployment of control practices due to its potential of causing yield loss of processing tomatoes. The monitoring of H. armigera adults using stick traps lured with sex pheromone was correlated to egg densities, larvae, and percentage of damaged fruits, aiming to subsidize control decisions only using the number of males caught in the traps since surveying pest stages or damaged fruits is laborious and costly. Surveys were carried out on 11 tomato fields (ca. 80 to 120 hectares each) for processing during the 2015 and 2016 crop seasons. The survey was initiated at the flowering stage with traps set up along the field borders 100 m distant each. Evaluations of adult male capture in the traps were conducted twice a week for 14 and 10 weeks during the 2015 and 2016 seasons, respectively. Simultaneously, 70 tomato plants were fully inspected for eggs, larvae, and damaged fruits per area using a rate of 10 plants per point of trap setting in each area. Overall capture of male moths correlated to subsequent eggs, larvae, and damaged fruits. Based on the outcome of the regression analysis between male moths captured and percentage of damaged fruits, the control decision is suggested when three to six male moths are captured per trap during one week. The monitoring of adults using pheromone traps help deploy chemical or biological control methods to restrain H. armigera population reaching economic threshold levels.

Abstract Cardiorenal syndrome type 1 (CRS 1) occurs when acute heart failure leads to acute kidney injury. There are several etiologies of CRS 1, including Chagas disease. Here, we present the first case report of CRS 1 in a patient with acute Chagas disease. Electrocardiography, transthoracic echocardiography, and cardiac magnetic resonance imaging showed signs of acute myocarditis. Laboratory examination revealed severe loss of kidney function, with a creatinine clearance of 30 mL/min, which fully normalized after treatment. Due to emergence of Chagas disease in the Brazilian Amazon, it is important to report unique clinical features in order to improve patients’ outcomes.

Resumo: O objetivo deste trabalho foi obter progênies de feijão-caupi (Vigna unguiculata) com inflorescência composta, pedúnculo curto, ciclo precoce, boa arquitetura de planta e alto potencial produtivo. O material genético inicial constituiu-se de 453 progênies F2:3, selecionadas a partir de dez cruzamentos e avaliadas em delineamento de blocos aumentados de Federer, com duas testemunhas. Dessas, selecionaram-se 60 progênies das gerações F4:5 e F4:6, que foram analisadas em dois experimentos sucessivos, ambos em delineamento látice 8x8, com quatro testemunhas e quatro repetições. A seleção precoce foi eficiente para fixação dos caracteres avaliados. Detectou-se ampla variabilidade genética entre e dentro das progênies. As herdabilidades e os ganhos genéticos estimados e realizados nas progênies F4:5 e F4:6 indicam a possibilidade de seleção de progênies precoces, com comprimento de pedúnculo curto, inflorescência composta e produtividade igual ou superior à das cultivares comerciais utilizadas como testemunhas.

Abstract: The objective of this work was to obtain cowpea (Vigna unguiculata) progenies with compound inflorescences, short peduncles, early cycle, good plant architecture, and high-yielding potential. The initial genetic material consisted of 453 F2:3 progenies, selected from ten crosses and evaluated using Federer’s augmented block design, with two controls. Of these, 60 progenies from the F4:5 and F4:6 generations were selected and assessed in two consecutive experiments, both in a 8x8 lattice design with four controls and four replicates. Early selection was efficient at fixing the evaluated traits. A wide genetic variability was detected among and within progenies. The estimated and obtained heritability and genetic gains in the F4:5 and F4:6 progenies indicate the possibility of selection of early progenies with short peduncles, compound inflorescences, and productivity similar to or greater than that of the commercial cultivars used as controls.

Resumen: En | Texto: En | PDF: En

ABSTRACT The aim of the present study was to investigate the bone mineral density (BMD) of patients with type 1 Diabetes mellitus (T1DM). We also assessed the association between osteoprotegerin (OPG) genetic polymorphisms and BMD. Genotyping was performed for 1181G>C and 163A>G OPG polymorphisms by allelic discrimination in 119 patients with T1DM and 161 normoglycemic (NG) individuals, aged 6 to 20 years old. Glycemic control, serum parameters of bone metabolism and BMD were evaluated. T1DM patients showed low BMD, poor glycemic control and decreased total calcium values when compared to controls (p < 0.05). For all the polymorphisms studied, the genotype and allele frequencies in patients with T1DM were not significantly different from the controls. In patients with T1DM, carriers of OPG 1181CC showed higher concentrations of ionized calcium compared to patients with GG+GC genotypes. These results suggest that low BMD is associated with poor glycemic control in T1DM. Despite the lack of a detected association between OPG polymorphisms and BMD in these patients, the increased ionized calcium in those carrying OPG 1181CC suggests a possible increase in osteoclastogenesis, a conclusion that may be supported by the lower BMD observed in these subjects.

A magnitude do erro experimental tem efeito direto no sucesso de experimentos, no melhoramento de plantas. Este trabalho objetivou verificar a interferência de métodos de correção de estande na produtividade de 25 híbridos de sorgo granífero, em sete ambientes. Os métodos avaliados foram: sem correção, regra de três, covariância de estande médio e de estande ideal, Zuber, Cruz, Vencovsky & Cruz e correção estratificada, com base no agrupamento de genótipos. O coeficiente de correlação de Pearson foi utilizado para verificar a magnitude da influência de cada método, em relação aos dados sem correção. Os métodos de correção de estande baseados em covariância e de Vencovsky & Cruz reduziram o coeficiente de variação e apresentaram alta correlação com parâmetros de adaptabilidade e estabilidade dos híbridos, no entanto, estas diferenças não foram expressivas a ponto de justificarem a correção.

The magnitute of the experimental error has a direct effect on the success of plant breeding experiments. This study aimed at evaluating the interference of stand correction methods on the yield of 25 grain sorghum hybrids, in seven environments. The methods tested were: without correction, rule of three, covariance of medium and ideal stand, Zuber, Cruz, Vencovsky & Cruz and stratified correction, based on genotype groups. The Pearson correlation coefficient was used to assess the magnitude of the influence exerted by each method, concerning the data without correction. The stand correction methods based on covariance and Vencovsky & Cruz reduced the coefficient of variation and showed a high correlation with the adaptability and stability parameters of hybrids, however, these differences were not so significant to justify such adjustment.

In the neonatal intensive care unit (NICU), the newborn (NB) receives emergency treatment as an attempt to improve their medical condition and there are several episodes of handling it. This research aimed at investigating the physiological and behavioral responses of newborns hospitalized in a NICU, and to propose a protocol for minimum handling of the NB in the NICU. It was an exploratory, descriptive, quantitative approach, performed in the NICU of a teaching hospital in Fortaleza, Ceará. There were samples of 26 NBs, and the data collection was performed in April 2010. It was found that the newborns had an average of eight physiological or behavioral responses. The main responses were: arching eyebrows, facial responses and increased muscle tone, which can pose to the newborn discomfort, dislocation and pain before the procedure. It was concluded that excessive handling alters the physiological and behavioral aspects of the newborn, so the protocol for minimum handling of the NB can be a strategy for maintaining the well-being.

En la Unidad de Terapia Intensiva Neonatal (UTIN), el recién nacido (RN) recibe tratamiento de urgencia para mejorar su condición clínica, con varios episodios de manejo. El objetivo fue verificar las respuestas fisiológicas y de comportamiento del recién nacido hospitalizado en la UTIN y proponer un protocolo de manejo mínimo del RN en la UTIN. Estudio exploratorio, descriptivo, planteo cuantitativo; realizado en la UTIN de un hospital universitario, en Fortaleza/ Ceará. Muestra de 26 RNs; los datos se recogieron en abril de 2010. Se comprobó que los recién nacidos presentaron un promedio de ocho respuestas fisiológicas o de comportamiento. Las principales fueron: arquear las cejas, respuestas faciales y aumento del tono muscular, lo que puede suponer para el recién nacido malestar, desorganización y dolor ante los procedimientos. Se concluye que el manejo excesivo altera los aspectos fisiológicos y de comportamiento del RN, de modo que el protocolo de manejo mínimo del RN puede ser una estrategia para mantener el bienestar.

Objetivou-se verificar as respostas fisiológicas e comportamentais do recém-nascido internado na UTIN e, propor um protocolo de manuseio mínimo do RN na UTIN. Estudo exploratório, descritivo, abordagem quantitativa; realizado na UTIN de um hospital-escola, em Fortaleza, Ceará. Amostra de 26 RNs, a coleta de dados foi realizada em abril de 2010. Constatou-se que todos os RNs apresentaram média de oito respostas fisiológicas ou comportamentais. As principais foram: arqueamento das sobrancelhas, respostas faciais e aumento do tônus muscular, as quais podem representar para o RN desconforto, desorganização e dor frente aos procedimentos. Conclui-se que o excesso de manuseio altera os aspectos fisiológicos e comportamentais do RN, de modo que o protocolo de manuseio mínimo do RN pode ser uma estratégia para a manutenção do bem-estar.

La leishmaniosis es una enfermedad infecciosa parasitaria, endémica, de distribución mundial, que en Venezuela se presenta como leishmaniosis tegumentaria americana (cutánea localizada, cutáneomucosa y cutáneo difusa) además de la forma visceral (kala azar). La variedad cutánea localizada representa el 90% de los casos atendidos en la consulta de Endemias Rurales del Instituto de Medicina Tropical y en los Servicios de Pediatría Médica y Enfermedades Infecciosas del Adulto del Hospital Universitario de Caracas, y la mayoría son tratados ambulatoriamente con antimoniato de meglumina. En algunas situaciones clínicas es necesaria la hospitalización. Se describen ocho casos hospitalizados: 1) niña de dos años con leishmaniosis cutánea que había recibido inmunoterapia para la parasitosis; 2) paciente de 59 años con leishmaniosis de la mucosa nasal; 3) paciente de 64 años con úlcera de los chicleros en el pabellón auricular; 4) paciente de 36 años con falla terapéutica a la meglumina, quien había recibido inmunoterapia para leishmaniosis; 5) paciente de 59 años alcohólico, con ulceración extensa de cinco años de evolución; 6) mujer de 83 años con leishmaniosis cutánea en miembros inferiores; 7) paciente con leishmaniosis de la mucosa nasal y SIDA; 8) paciente de 37 años con kala azar. Se analizan las razones para la hospitalización y las dosis de antimoniato de meglumina empleadas para la solución terapéutica.

Leishmaniasis is an endemic parasitic infectious disease of worldwide distribution. In Venezuela the main characteristics correspond to american tegumentary leishmaniasis (cutaneous localized, cutaneous-mucous, cutaneous diffuse) and visceral leishmaniasis (kala azar). The localized cutaneous variety represents 90% of the cases attended at the ambulatory medical clinic for rural endemic diseases at the Tropical Medicine Institute, Pediatric and Adult services for Infectious Diseases at the Universitary Hospital of Caracas, and these patients are treated with pentavalent antimonials. In some clinical conditions hospitalization is required. We describe eight cases of patients treated under hospitalization. Case 1) a two year old girl with cutaneous leishmaniasis who had received immunotherapy for this parasitic disease; case 2) fifty nine year old female with nasal leishmaniasis; case 3) sixty four year old male with a rubber tapper’s ulcer in the ear; case 4) thirty six year old male with treatment failure to pentavalent antimonials having received immunotherapy for leishmaniasis; case 5) fifty nine year old male alcoholic patient, with extended ulcer of five years evolution; case 6) eighty three year old female with cutaneous leishmanisis in the legs; case 7) thirty three year old male with leishmaniasis of the nasal mucosa and AIDS; case 8) thirty seven year old male with kala azar. We discuss the reasons for hospitalization and the dosage of pentavalent antimonials administered.
