Abstract Introduction Systemic arterial hypertension (SAH) is responsible for 9.5 million deaths in the global popu-lation. Lifestyle factors, including physical inactivity, are important modifiable risk factors in the development of SAH. Thus, physical exercise has been shown to be effective to control SAH and before the prescription, the six-minute walk test (6-MWT) has been commonly used to assess the physical capacity. Objective To propose reference values for the 6-MWT test in Brazilian people with SAH. Methods A cross-sectional observational study was conducted with 302 hypertensive subjects (62.61 + 10.93 years) admitted to a cardiac rehabilitation program. Participants were divided into different age quartiles and submitted to 6-MWT. The walking distance data was compared between the quartiles and adjusted by mul-tiple linear regression analysis. Results The hypertensive subjects walked 388.07 + 115.03 m during the 6-MWT. No significant difference between the genders was found. However, when the age quartiles were compared, for the 46–59 age group, the women walked less than the men. Intra-group comparisons showed that the distance walked in the 6-MWT decreased with the increase in age, in both men and women. Conclusion The present study provides reference values for the 6-MWT, both for Brazilian men and women of different age groups. This data may be an important parameter for future clinical studies, prevention strategies, and clinical intervention.

Resumo Introdução A hipertensão arterial sistêmica (HAS) é respon-sável por 9,5 milhões de mortes na população mundial. Con-dições do estilo de vida, incluindo a inatividade física, são importantes fatores de risco modificáveis no desenvolvimento da HAS. Desse modo, o exercício físico tem se mostrado eficaz no controle da HAS e, antes da prescrição, o teste de caminhada de seis minutos (TC6) tem sido comumente utilizado para ava-liar a capacidade física. Objetivo Propor valores de referência para o teste de TC6 em brasileiros com HAS. Métodos Realizou-se um estudo observacional transversal com 302 hipertensos (62,61 + 10,93 anos) admitidos em um programa de reabilitação cardíaca. Os participantes foram divididos em diferentes quartis de idade e submetidos ao TC6. Os dados de distância percorrida foram comparados entre os quartis e ajustados por análise de regressão linear múltipla. Resultados Os hipertensos caminharam 388,07 + 115,03 m durante o TC6. Não encontrou-se diferença significativa entre os gêneros. No entanto, quando comparados os quartis de idade, para a faixa etária de 46 a 59 anos, as mulheres caminharam menos do que os homens. As comparações intragrupo mostraram que a distância percorrida no TC6 diminuiu com o aumento da idade, tanto em homens quanto em mulheres. Conclusão O presente estudo fornece valores de referência para o TC6, tanto para homens quanto para mulheres brasileiras de diferentes faixas etárias. Esses dados podem ser um parâmetro importante para futuros estudos clínicos, estratégias de prevenção e intervenção clínica.

This is a multicenter, cross-sectional study carried out with students regularly enrolled in undergraduate courses at eight Brazilian IFES. Data collection was conducted between October 2021 and February 2022 using an online self-completed questionnaire, which addressed sociodemographic and academic characteristics, lifestyle habits, and health conditions. Symptoms of anxiety and depression were assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Variables were analyzed descriptively using frequency distribution and Pearson’s chi-square test. To estimate the prevalence of symptoms of anxiety and depression, the proportion and 95% confidence interval (95%CI) were used. The level of adopted statistical significance was 5%.

ABSTRACT Objectives: We aimed to evaluate the association between the triglyceride glucose index (TyG index) and sleep quality and to establish a cut-off value for the TyG index based on the prevalence of subjects with insulin resistance (IR). Materials and methods: This cross-sectional study involved Brazilian health professionals (20-59 years). A total of 138 subjects answered the Pittsburgh Sleep Quality questionnaire to evaluate sleep quality. They were categorized into two groups: good sleep quality (global score ≤ 5 points) and poor sleep quality (global score ≥ 6 points). Also, we classified the subjects as having a high (>8.08 or >4.38) or low TyG index (≤8.08 or ≤4.38). Results: The majority of the subjects (70%) with high TyG index values (>8.08 or >4.38) reported poor sleep quality (p ≤ 0.001). Those with poor sleep quality had a 1.44-fold higher prevalence of IR (TyG index >8.08 or >4.38) compared to those with good sleep quality, regardless of sex, total cholesterol, LDL/HDL ratio, insulin, complement C3, CRP, and adiponectin (p ≤ 0.001). Conclusion: Our data showed a positive and significant association between the TyG index and poor sleep quality. Thus, these findings support the association between poor sleep quality and IR.

Resumo O objetivo deste trabalho foi caracterizar o padrão de distribuição espacial da A. nahoumii em diferentes gradientes de altitudes, bem como realizar o levantamento florístico da vegetação associada a A. nahoumii, considerada endêmica e “Vulnerável”. O estudo foi realizado na Serra da Jibóia, Santa Teresinha, Bahia, Brasil. Foi realizado um inventário de plantas jovens e adultas da A. nahoumii, bem como a identificação taxonômica e quantificação das espécies associadas, percentagem de cobertura da vegetação, percentagem de cobertura da A. nahoumii, inclinação da rocha, percentagens de matéria orgânica e rocha exposta. Foram calculados os parâmetros fitossociológicos: densidade absoluta, densidade relativa, frequência absoluta, frequência relativa e dominância da A. nahoumii. Para a distribuição espacial foram testados três índices: Índice de Morisita, McGuinnes e Payandech. Também foi realizada uma Análise de Correspondência Canônica para as variáveis ambientais com as espécies da comunidade. Um total de 1.660 indivíduos foram encontrados e classificados taxonomicamente em 17 famílias, 25 gêneros e 28 espécies. O padrão de distribuição espacial da população de A. nahoumii é agregado. Os resultados demonstram que a estrutura populacional da A. nahoumii está estável, mas eventos como queimadas e exploração extrativista, as tornam vulnerável, juntamente com as demais espécies que habitam a área.

Abstract The objective of this study was to characterize the spatial distribution pattern at different altitude gradientes as well as to investigate the flora associated with A. nahoumii, considered to be endemic and vulnerable. The study was carried out in Serra da Jibóia, Santa Teresinha, Bahia, Brazil. An inventory was conducted of Young and adult A. nahoumii specimens along with taxonomic identification and quantification of the associated species. The cover percentage of A. nahoumii, rock slope, organic matter percentage and exposed rock percentage were calculated, as well as the following phytosociological parameters: absolute density, relative density, absolute frequency, relative frequency, and dominance of A. nahoumii. For the spatial distribution, three indices were tested (Morisita, McGuinnes and Payandech). Canonical correspondence analysis was also applied to test the association of the environmental variables with the species in the community. A total of 1,660 individuals were encountered and classified according to taxonomy in 17 families, 25 genera and 28 species. The spatial distribution pattern of the A. nahoumii population is aggregate. The results demonstrate that the population structure of A. nahoumii is stable, but events such as fires and extractive exploitation make the species vulnerable, along with the other species that inhabit the area.

ABSTRACT Alcantarea nahoumii occurs exclusively in the state of Bahia, Brazil, and is classified as vulnerable due to deforestation and frequent fires in the region. Knowledge of floral and reproductive biology is fundamental to understanding ecological interactions, as well as the reproductive success of plant species. The objective of this study was to evaluate the floral and reproductive biology of A. nahoumii in an Atlantic Forest fragment with regard to phenology, pollen viability, stigma receptivity, pollination ecology and reproductive systems, all of which are important parameters for of the development of conservation strategies for the species. Anthesis is diurnal and heterogeneous, starting at 6:30 a.m. and lasting until 8:00 a.m. Highest germination percentages and greatest pollen tube lengths were obtained in BK culture medium. Histochemical tests revealed high pollen viability (89.71 %). Stigma receptivity occurred during anthesis and lasted for up to 24 hours after floral opening. Alcantarea nahoumii exhibited preferential allogamy and self-compatibility, and required a pollinator to production of viable seeds. Sixteen species of pollinators were observed visiting A. nahoumii, among which were five hummingbird species. Even though its reproductive system is efficient, this bromeliad remains threatened mainly due to habitat fragmentation caused by deforestation, burning and predatory extractivism.

RESUMO. A Embrapa Mandioca e Fruticultura desenvolveu híbridos de abacaxi ornamental para diferentes usos, dentre eles, flor de corte, plantas de vaso e paisagismo. O objetivo desse estudo foi realizar a avaliação clonal de dois híbridos ornamentais usando descritores morfológicos quantitativos e qualitativos, a fim de serem recomendados como novas cultivares de abacaxis ornamentais. Vinte plantas de cada híbrido (PL01 e PL04) foram avaliadas em dois ciclos de produção em relação à resposta à indução floral, bem como a estabilidade e homogeneidade dos clones. Foram realizadas estatísticas descritivas e uma analise para determinação da distância genética, com base no algoritmo de Gower. Foram formados quatro grupos, sendo dois com os parentais e dois com os diferentes híbridos avaliados nos dois ciclos da cultura. No que se refere a avaliação do florescimento, do plantio no campo até o ponto de corte foram aproximadamente 17 meses no primeiro ciclo e 13,5 meses no segundo ciclo para ambos os híbridos. Os híbridos se caracterizaram como uma novidade no segmento de flores mostrando-se estáveis e homogêneos e podem ser recomendados como novas cultivares de abacaxi ornamental por apresentarem qualidade satisfatória e atenderem as exigências de mercado.

ABSTRACT. Embrapa Cassava and Fruits has developed ornamental pineapple hybrids for several categories of ornamental use including cut flowers, potted plants and landscaping. The objective of this study was to carry out a clonal evaluation of two ornamental hybrids using quantitative and qualitative morphological descriptors to recommend these hybrids as new ornamental pineapple cultivars. Twenty plants of each hybrid (PL01 and PL04) were evaluated regarding the response to floral induction as well as the stability and homogeneity of the clones in two production cycles. The descriptive statistics were calculated and analyzed to determine the genetic distance based on the Gower algorithm. Four groups were formed, two using parental data and the other two containing the different hybrids that were evaluated in the two growing cycles. In the floral evaluation, the time from field planting to harvest of the stem as a cut flower was determined to be as long as 17 months in the first cycle and 13.5 months in the second cycle for both hybrids. They were characterized as a novelty in the flower market; they showed genetic stability and homogeneity and can be recommended as new cultivars of ornamental pineapple because they exhibit satisfactory quality and meet the market requirements.

Este trabalho teve como objetivo estudar a embriogênese somática e a regeneração de plantas da variedade Cigana Preta a partir de ápices caulinares e folhas imaturas obtidos de plantas cultivadas in vitro. Para a indução de embriões, os explantes foram cultivados em meio Murashige e Skoog (MS) suplementados com ácido 2,4 diclorofenoxiacético (2,4-D) ou 4-amino-3,5,6-trichloropicolinic acid (Picloram), ambos nas concentrações 8,0 e 12 mg L-1. O desenvolvimento dos embriões obtidos foi testado por dois meios de cultura com diferentes concentrações de benzilaminopurina (BAP) (D1 ou D2). Embriões em estágio cotiledonar foram incubados em meio de germinação, constituído de sais e vitaminas do MS, 2,0 µM de sulfato de cobre, 2,4 g L-1 de Phytagel®, e 1,77 µM BAP. A maior frequência de calos e números de embriões por explantes foi obtida com 8,0 mg L-1 da auxina Picloram. As plantas regeneradas, oriundas do tratamento com Picloram apresentaram desenvolvimento normal e num período mínimo de quatro semanas foram transferidas para meio de multiplicação. Cortes histológicos de embriões malformados, provenientes dos explantes foliares cultivados em 2,4-D revelaram que as estruturas cotiledonares têm origens independentes da formação do meristema apical caulinar e não houve formação do meristema apical caulinar nos embriões, sendo a maioria classificado como corneta. Este trabalho demonstrou que em mandioca o uso de diferentes auxinas proporciona diferentes condições para a formação de embriões somáticos e que a baixa conversão em plantas foi decorrente de anormalidades desses embriões.

In this study, the somatic embryogenesis and regeneration of Cigana Preta plants from shoot apices and immature leaves taken from plants cultivated in vitro were examined. To embryo induction the explants were cultivated in Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) or 4-amino-3,5,6-trichloropicolinic acid (Picloram) at concentrations of 8.0 and 12 mg L-1. To development of embryos two media cultures with different concentration of BAP (D1 or D2) were evaluated. Embryos in the cotyledonary stage were incubated in germination medium containing MS salts and vitamins, 2.0 µM copper sulfate, 2.4 g L-1 of Phytagel® and 1.77 µM BAP. The highest frequency of calluses and the greatest number of embryos per explant were obtained using the auxin picloram at a concentration of 8.0 mg L-1. The plants regenerated in the picloram treatment exhibited normal development and were transferred to a multiplication medium after a minimum of four weeks. The histological sections of the malformed embryos from foliar explants cultured in the presence of 2,4-D demonstrated that the origin of the cotyledonary structures was independent of the formation of the shoot apical meristem, which was not formed in the embryos, and the majority of the embryos were classified as cornet-shaped. This study demonstrates that in cassava, the use of different auxins provides different conditions for the formation of somatic embryos, and the low rate of conversion into plants results from abnormalities in the embryos.

Introduction: Visceral fat accumulation is associated with several changes, such as, increased production of inflammatory biomarkers, especially, C-reactive protein (CRP) and fibrinogen. Anthropometric measurements for central adiposity evaluation, such as, waist circumference (WC) and sagittal abdominal diameter (SAD) have been highlighted. However, there is no consensus on the best anatomical site for measurement. Objective: To evaluate the reliability of different measurements of WC and SAD and verify their capacity to discriminate changes in inflammatory biomarkers. Method: 130 men (20-59 years) were assessed, having measurements of weight, height, WC and SAD. It was considered as the cutoff point for high-sensitivity CRP (hs-CRP) values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: All measurements presented an intraclass correlation coefficient between 0.998 and 0.999. WC measured at the umbilical level (AUC=0.693±0.049) and the smallest circumference between the thorax and the hips (AUC=0.607±0.050) had greater ability to discriminate changes in concentrations of hs-CRP and fibrinogen, respectively. SAD (umbilical level) showed the better ability to detect changes in concentrations of hs-CRP (AUC=0.698± 0.049) and fibrinogen (AUC=0.625±0.049), according to the ROC analysis (p<0.05). Conclusion: WC (smallest circumference between the thorax and the hips) and SAD (umbilical level) are the anatomic sites of measurement for use in predicting the inflammatory risk in apparently health men.

Introducción: La acumulación de grasa visceral se asocia con varios cambios, tales como, aumento de la producción de los biomarcadores inflamatorios, en especial, la proteína C-reactiva (PCR) y fibrinógeno. Las medidas antropométricas para la evaluación de la adiposidad central, como la circunferencia de la cintura (CC) y el diámetro abdominal sagital (DAS) se han destacado. Sin embargo, no hay consenso sobre el mejor sitio anatómico para la medición. Objetivos: Evaluar la fiabilidad de diferentes mediciones de CC y DAS y verificar su capacidad para discriminar los cambios en biomarcadores inflamatorios. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso, estatura, circunferencia de la cintura (CC) y diámetro abdominal sagital (DAS). Se consideró como punto de corte para los valores de PCR ultrasensible (PCR-us) ≥ 0,12 mg/dL y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: Todas las mediciones presentaron un coeficiente de correlación intraclase entre 0.998 y 0.999. CC medida a nivel umbilical (AUC=0,693±0,049) y la circunferencia más pequeña entre el tórax y las caderas (AUC=0,607±0,050) tuvieron una mayor capacidad para discriminar los cambios en las concentraciones de PCR-us y fibrinógeno, respectivamente. DAS (nivel umbilical) mostró la mejor capacidad para detectar cambios en las concentraciones de PCR-us (AUC=0,698±0,049) y fibrinógeno (AUC=0,625±0,049), de acuerdo con el análisis ROC (p<0,05). Conclusiones: CC (circunferencia más pequeña entre el tórax y las caderas) y DAS (nivel umbilical) son los sitios anatómicos de elección para su uso en la predicción del riesgo inflamatorio en hombres adultos sanos.

O uso do abacaxi como planta ornamental vem se intensificando nos últimos anos, por sua beleza e originalidade e é crescente a demanda por novas variedades. O objetivo desse trabalho foi estudar a variabilidade genética em progênies de abacaxi ornamental, identificando as formas de uso e a resistência à fusariose dos híbridos selecionados. Foram aplicados onze descritores morfológicos em seis progênies: FRF-22 X FRF-1387, FRF-1392 X FRF-32, Curauá Roxo X Ananás Tricolor, G-44 X FRF-1387, FRF-1392 X FRF-224 e FRF-1387 X FRF-224, sendo os híbridos enquadrados nas categorias de paisagismo, corte, vaso, minifrutos e folhagens e cerca-viva. Em paralelo foi estudado a resistência a fusariose dos híbridos selecionados. Foi verificada grande variabilidade entre e dentro das progênies, permitindo selecionar 16 híbridos para flor de corte, 17 para paisagismo, quatro para minifrutos, dois para vasos e apenas três para folhagem, sendo 14 com mais de uma forma de uso. Dos 31 híbridos avaliados para a fusariose, 11 apresentaram resistência, 17 moderadamente resistente e três suscetíveis.

The use of pineapples as ornamental plants has increased in the last years due to their beauty and originality, demanding the generation of new varieties. The objective of the present work was to study the genetic variability and type of use of hybrids as ornamental pineapples, besides evaluating the resistance of these hybrids to Fusarium wilt. Six progenies, FRF-22 X FRF-1387, FRF-1392 X FRF-32, Curauá Roxo X Ananás Tricolor, G-44 X FRF-1387, FRF-1392 X FRF-224 and FRF-1387 X FRF-224, were evaluated by eleven morphological descriptors, and five categories of use were taken into account: landscaping plants, cut flower, potted plants, minifruits and foliage. High variability within and between progenies was detected, which allowed the selection of 16 hybrids as cut flowers, 17 as landscaping plants, four as minifruits, two as potted plants and just three as foliage. Fourteen of them were recorded for more than one type of use. For resistance to the Fusarium, out of the 31 hybrids evaluated, 11 presented resistance, 17 were moderately resistant and three were susceptible.

Introduction: Epidemiological studies have shown an association between coronary heart disease and emerging cardiovascular risk factors, such as, levels of fibrinogen and high-sensitivity C-reactive protein (hs-CRP). Objectives: To verify the ability of biochemical indicators in discriminating changes in the levels of hs-CRP and fibrinogen, in apparently healthy adult men. Methods: Were evaluated 130 apparently healthy men (20-59 years), having measurement of weight and height. Biochemical measurements (lipid profile, fasting glucose, uric acid, hs-CRP and fibrinogen) were performed. Body mass index, total cholesterol/HDL-c and LDL-c/HDL-c ratios were calculated. It was considered as the cutoff point for hs-CRP values > 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: The uric acid showed the best correlation (r = 0.325) and the higher area under the ROC curve (0.704 ± 0.054), showing greater ability to discriminate higher levels of hs-CRP (p < 0.01). The total cholesterol/HDL-c ratio (r = 0.222) and the LDL-c/HDL-c ratio (r = 0.235) showed the best correlations and the higher areas under the ROC curves (0.624 ± 0.049 and 0.624 ± 0.049) in identify higher levels of fibrinogen (p < 0.05). Conclusion: The uric acid and the total cholesterol/HDL-c and the LDL-c/HDL-c ratios showed greater ability to identify changes in the levels of hs-CRP and fibrinogen, respectively. It was suggested the use of biochemical markers in the clinical practice, in order to establish preventive action for cardiovascular disease in apparently healthy adult men.

Introducción: Los estudios epidemiológicos han demostrado una asociación entre la enfermedad coronaria y nuevos factores de riesgo cardiovascular, como, los niveles de proteína C-reactiva ultrasensible (PCR-us) y fibrinógeno. Objetivos: Evaluar la capacidad de los indicadores bioquímicos en discriminar cambios en los niveles de PCR-us y fibrinógeno, en hombres adultos sanos. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso y talla. Se realizó mediciones bioquímicas (perfil lipidico, glucosa en ayunas, ácido úrico, PCR-us y fibrinógeno). Se calculó el índice de masa corporal, la relación colesterol total/HDL-c y la relación LDL-c/HDL-c. Se consideró como punto de corte para los valores de PCR-us > 0,12 mg/dL y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: El ácido úrico mostró la mejor correlación (r = 0,325) y el área más alta bajo la curva ROC (0,704 ± 0,054), mostrando una mayor capacidad predictiva para detectar niveles más altos de PCR-us (p < 0,01). La relación colesterol total/HDL-c (r = 0,222) y la relación LDL-c/HDL-c (r = 0,235) mostraron una mejor correlación y el área más alta bajo la curva ROC (0,624 ± 0,049 y 0,624 ± 0,049) en la identificación de niveles más altos de fibrinógeno (p < 0,05). Conclusiones: El ácido úrico y la relación colesterol total/HDL-c y la relación LDL-c/HDL-c mostraron una mayor capacidad predictiva para detectar cambios en los niveles de PCR-us y fibrinógeno, respectivamente. Se sugirió el uso de marcadores bioquímicos en la práctica clínica, a fin de establecer medidas preventivas para la enfermedad cardiovascular en hombres adultos sanos.

Introduction: Obesity has been considered a chronic subclinical inflammation. High sensitivity C-reactive protein (hs-CRP) and fibrinogen are increasingly associated with cardiovascular risk. Objectives: To evaluate the ability of anthropometric and body composition indicators in discriminating higher levels of hs-CRP and fibrinogen. Methods: 130 men (20-59 years) were assessed, having measurement of weight, height, waist circumference (WC), hip and thigh circumferences, sagittal abdominal diameter (SAD), coronal diameter (CD) and body composition. Conicity index, waist/height ratio, body mass index, waist/hip ratio, waist/thigh ratio and sagittal index were calculated. It was considered as the cutoff point for hs-CRP values ≥ 0.12 mg/dL and for fibrinogen the 50th percentile of the evaluated sample. Results: Sagittal index (r = 0.280), waist/thigh ratio (r = 0.233) and waist/height ratio (r = 0.233) showed the best correlation with hs-CRP (p < 0.01). Conicity index (r = 0.305) and waist/height ratio (r = 0.279) showed the best correlation with fibrinogen (p < 0.01). In ROC analysis, the SAD (0.698 ± 0.049) and the conicity index (0.658 ± 0.048) had greater ability to discriminate cardiovascular risk through higher levels of hs-CRP and fibrinogen, respectively (p < 0.01). The cutoff points of 30 cm, 89.9 cm and 20.5 cm were the ones that reached largest sum between sensitivity and specificity values for the CD, WC and SAD, respectively. Conclusions: The SAD and the conicity index demonstrated a greater ability to detect higher levels of hs-CRP and fibrinogen, respectively, in apparently healthy adult men.

Introducción: La obesidad ha sido considerada como una inflamación crónica subclínica. La proteína C-reac-tiva ultrasensible (PCR-us) y el fibrinógeno se han asociado cada vez más con el riesgo cardiovascular. Objetivos: Evaluar la capacidad, de los indicadores antropométricos y de composición corporal, en discriminar mayores niveles séricos de PCR-us y fibrinógeno. Métodos: Se evaluaron 130 hombres (20-59 años). Se midió peso, estatura, circunferencia de la cintura, de la cadera y del muslo, diámetro abdominal sagital (DAS), diámetro coronal (DC) y composición corporal. Se calculó el índice de conicidad, la relación cintura/estatura, el índice de masa corporal, la relación cintura/cadera, la relación cintura/muslo y el índice sagital. Se consideró como punto de corte para los valores de PCR-us ≥ 0,12 mg/dl y para el fibrinógeno se utilizó el percentil 50 de la muestra evaluada. Resultados: El índice sagital (r = 0,280), la relación cintura/muslo (r = 0,233) y la relación cintura/estatura (r = 0,233) mostraron una mejor correlación con la PCR-us (p < 0,01). El índice de conicidad (r = 0,305) y la relación cintura/estatura (r = 0,279) mostraron una mejor correlación con el fibrinógeno (p < 0,01). En el análisis ROC, el DAS (0,698 ± 0,049) y el índice de conicidad (0,658 ± 0,048) mostraron una mayor capacidad predictiva de riesgo cardiovascular determinado a través de mayores niveles de PCR-us y fibrinógeno, respectivamente (p < 0,01). Los puntos de corte de 30 cm, 89,9 cm y 20,5 fueron los que alcanzaron mayor sumatorio entre los valores de sensibilidad y especificidad para el DC, circunferencia de la cintura y DAS, respectivamente. Conclusiones: En hombres adultos sanos, el DAS y el índice de conicidad mostraron una mayor capacidad predictiva para detectar niveles más altos de PCR-us y fibrinógeno respectivamente.

O objetivo deste trabalho foi avaliar a influência dos reguladores vegetais ácido naftalenoacético (ANA) e ácido giberélico (AG3) no estiolamento in vitro e posterior regeneração de plantas do abacaxizeiro híbrido PE x SC-60. Segmentos nodais de plantas produzidas in vitro, com aproximadamente 5-7 cm de comprimento, foram incubados em meio de cultura MS em sua concentração básica, suplementados com 0,0; 0,5 e 1,0 mg L-1 de ácido naftalenoacético (ANA) em combinação com ácido giberélico (AG3), nas concentrações de 0,0; 0,5 e 1,0 mg L-1, e mantidos a 27ºC e sob condições de escuro. As avaliações foram realizadas aos 90; 180 e 270 dias de incubação. Os melhores resultados foram obtidos com a concentração de 1,0 mg L-1 de ANA. No experimento posterior de regeneração, hastes com 3 cm, oriundas dos tratamentos de estiolamento foram cultivadas em meio de proliferação, quando aos 60 dias de cultivo avaliou-se o número de plantas regeneradas por tratamento. O tratamento que resultou ser mais efetivo para o estiolamento das plantas foi o que apresentou maior dificuldade de regeneração, demonstrando o efeito residual do regulador auxina na regeneração de plantas de híbrido de abacaxi.

This work aimed to evaluate the influence of naphthaleneacetic acid (NAA) and gibberellic acid (GA3) plant regulators in in vitro etiolation and subsequent regeneration of the PE x SC-60 pineapple hybrid. Nodal segments of in vitro plants with approximately 5-7 cm height were incubated in basic MS culture medium supplemented with 0.0; 0.5 and 1.0 mg L-1 of naphthaleneacetic acid (NAA) in combination with gibberellic acid (GA3) in concentrations of 0.0; 0.5 and 1.0 mg L-1, and maintained at 27 ºC under dark condition. Evaluations were carried out at 90 and 180 days after incubation period. The best results for length of etiolated stems were obtained with 1.0 mg L-1 of NAA. In the experiment followed by the regeneration, stems with 3 cm from the etiolation treatment, were cultivated in proliferation medium and the number of regenerated plants per treatment was evaluated at 60 days of cultivation. The treatment that promoted the best etiolation of plants also promoted the worst regeneration rates, demonstrating the residual effect of the auxin used in the previous step in the regeneration of plants of the pineapple hybrid evaluated.
