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.

ABSTRACT With the objective of evaluating the sustainability of cocoa-producing farms in the Puebloviejo canton, Los Ríos province (Ecuador), through indicators proposed by Sarandón et al. (1), the sustainability of 101 farms cultivated with CCN51 and Nacional cocoa was measured and compared; To this end, a three-stage investigation was carried out. The first consisted of defining indicators by dimensions (economic, ecological, and sociocultural) and validating indicators through experts. In the second stage, field work was carried out in which information was collected on the economic, environmental and sociocultural aspects of the farms and a third part in which statistical analyzes and radial graphs were carried out. The results show that the farms producing National cocoa, obtained a General Sustainability Index (ISG) of 1.89, achieving a value of 3.0 only in the Sociocultural Indicator (ISC), the farms producing cocoa CCN-51, they achieved an ISG of 2.26, reaching a value of 3.8 in the ISC, showing that most of the farms have low sustainability. It is concluded that important improvements must be made in the evaluated variables, especially in those that obtained values lower than 2, which will lead to the improvement of the productive units in the Puebloviejo canton.
RESUMEN Con el objetivo de evaluar la sustentabilidad en fincas productoras de cacao del cantón Puebloviejo, provincia de Los Ríos (Ecuador), mediante indicadores propuestos por Sarandón et al. (1), se midió y comparó la sustentabilidad de 101 fincas cultivadas con cacao CCN51 y Nacional; para ello, se realizó una investigación en tres etapas, la primera consistió en la definición de indicadores por dimensiones (económica, ecológica y sociocultural) y validación de indicadores mediante expertos; en la segunda etapa se realizó un trabajo de campo en el cual se efectuó un levantamiento de información de los aspectos económicos, ambientales y socioculturales de las fincas y una tercera parte en la que se realizaron análisis estadísticos y gráficos radiales. Los resultados muestran que las fincas productoras de cacao Nacional, obtuvieron un Índice General de Sustentabilidad (ISG) de 1,89, logrando un valor de 3,0 solo en el Indicador Sociocultural (ISC), las fincas productoras de cacao CCN-51, lograron un ISG de 2,26, alcanzando un valor de 3,8 en el ISC, mostrando que la mayoría de las fincas tienen baja sostenibilidad. Se concluye que se deben realizar mejoras importantes en las variables evaluadas, sobre todo en aquellas que se obtuvieron valores inferiores a 2, lo que conllevará al mejoramiento de las unidades de productivas en el cantón Puebloviejo.

Resumen Se estudió la parte aérea de Lotus corniculatus L. genotipo 202700 de hábito erecto originaria de Uruguay, se realizó un análisis de crecimiento, evaluando las variables rendimiento de MS (RMS), altura con regla (AR), altura con plato (AP), rendimientos de hoja (H), tallo (T), maleza (M), material muerto (MM), relación (H:T) y radiación interceptada (RI). Inmediatamente después del corte de uniformidad a 5 cm, se realizaron cortes semanales continuos durante un ciclo de rebrote (ocho semanas) en primavera. Esta investigación se llevó a cabo en ‘Predio Nuevo’ del Colegio de Postgraduados, Montecillo, Texcoco, Estado de México, del 12 de abril al 31 de mayo de 2021. Los datos se analizaron con SAS, conforme a un diseño experimental completamente al azar en parcelas divididas a dos densidades como tratamientos (D1= 12 000 plantas ha-1 y D2= 16 000 plantas ha-1) y ocho repeticiones para cada tratamiento. El tratamiento D2 de acuerdo con los resultados fue el que presentó los valores más altos 5 450 kg de MS ha-1 seguido por el tratamiento D1 con 4 315 kg de MS ha-1, la radiación interceptada (%) por tratamiento 77% para la D1 y 83% para la D2 alcanzando el punto máximo a los 49 días (92%), la altura de las plantas se comportó de manera positiva conforme se desarrollaba la pradera. Se concluye que la densidad con mejor comportamiento general fue la D2 misma que registro la mayor respuesta en términos de variable hoja, tallo, maleza, material muerto (kg de MS ha-1).
Abstract The aerial part of Lotus corniculatus L. genotype 202700 of erect habit originating in Uruguay was studied, a growth analysis was performed, evaluating the variables DM yield (DMY), height with ruler (HR), height with plate (HP), yields of leaf (L), stem (S), weeds (W), dead material (DM), (L:S) ratio and intercepted radiation (IR). Immediately after the uniformity cut at 5 cm, continuous weekly cuts were made during a regrowth cycle (eight weeks) in spring. This research was carried out in ‘Predio Nuevo’ of the College of Postgraduates, Montecillo, Texcoco, State of Mexico, from April 12 to May 31, 2021. Data were analyzed with SAS, according to a completely randomized experimental design in split plots at two densities as treatments (D1= 12 000 plants ha-1 and D2= 16 000 plants ha-1) and eight repetitions for each treatment. According to the results, the treatment D2 was the one that presented the highest values 5 450 kg DM ha-1, followed by the treatment D1 with 4 315 kg DM ha-1, the intercepted radiation (%) by treatment 77% for D1 and 83% for D2, reaching the peak at 49 days (92%), the height of the plants behaved positively as the meadow developed. It is concluded that the density with the best overall behavior was D2, which showed the greatest response in terms of the variables leaf, stem, weeds, dead material (kg DM ha-1).

ABSTRACT Malathion is one of the most widely used pesticides in Mexico and the world. Its indiscriminate use has placed it as the main pesticide detected in food products, causing health problems such as increased oxidative stress, insulin resistance, and alteration of lipid metabolism. Furthermore, the consumption of different species of Lactobacillus with probiotic capacity has been associated with other effects on health, including the reduction of alterations related to the consumption of pesticide residues. The objective of the present study was to determine the resistance of eight Lactobacillus species to different concentrations of malathion and evaluate which could be used to reduce the toxic effects of this pesticide on health. Eight Lactobacillus species present in food supplements were isolated and identified by polymerase chain reaction (PCR), and their resistance to the insecticide malathion 1000 at different concentrations was evaluated using the Kirby-Bauer technique. All Lactobacillus species considered, except L. salivarius, could grow in the presence of malathion at low doses (0.1, 1 %); however, resistance at medium doses (10, 20 %) varies between species, while at high doses (50, 83.6 %) there was no growth, or the number of colonies were was visibly lower compared to the control group. Considering the previous data, we can conclude that the resistance of Lactobacillus spp. at different concentrations of malathion varies according to the species, and seven of the eight species evaluated could present a potential beneficial effect when consuming food contaminated with malathion residues.
RESUMEN El malatión es uno de los plaguicidas más utilizados en México y el mundo. Su uso indiscriminado lo ha situado como el principal plaguicida detectado en productos alimenticios, lo que ocasiona problemas de salud como aumento del estrés oxidante, resistencia a la insulina y alteración del metabolismo de lípidos. El consumo de distintas especies de Lactobacillus con capacidad probiótica se ha asociado con diferentes efectos sobre la salud, incluyendo disminución de las alteraciones asociadas al consumo de residuos de plaguicidas. El objetivo del presente estudio fue determinar la resistencia de ocho especies de Lactobacillus a diferentes concentraciones de malatión y evaluar cuáles podrían utilizarse para reducir los efectos tóxicos del malatión sobre la salud. Se aislaron e identificaron mediante la técnica de reacción en cadena de la polimerasa (conocida como PCR, por sus siglas en inglés) ocho especies de Lactobacillus presentes en suplementos alimenticios y se probó su resistencia a diferentes concentraciones del insecticida malatión 1000 mediante la técnica de Kirby-Bauer. Todas las especies de Lactobacillus evaluadas, con excepción de L. salivarius, fueron capaces de crecer en presencia de malatión a dosis bajas (0.1, 1 %), sin embargo, la resistencia a dosis medias (10, 20 %) varía entre especies, mientras que a dosis altas (50, 83.6 %) no hubo crecimiento o el número de colonias fue visiblemente menor respecto al grupo control. Tomando en cuenta los datos anteriores se puede concluir que la resistencia de Lactobacillus spp. a diversas concentraciones de malatión varía de acuerdo con la especie y que siete de las ocho especies evaluadas podrían presentar un potencial efecto benéfico ante el consumo de alimentos contaminados con residuos de este plaguicida.

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp;
Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities.
nbsp;
Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp;
The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp;
The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp;
Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.
Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou.
A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica.
Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas.
A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica.
A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp;
Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

Abstract Iodine (I) is a non-essential element for plants; however, the application of the element has shown positive effects on plants grown in optimal conditions or under stress. The objective of this experiment was to evaluate the impact of iodine on the concentration of phenolic compounds, antioxidant capacity and photosynthetic pigments in leaves of three fig cultivars subjected to salt stress. Eight-month-old fig plants were established under a completely randomized experimental design with a 3x2x2 factorial arrangement: three fig cultivars (Ficus carica L.): Brown Turkey, Kadota and Black Mission; two levels of NaCl (0 and 100 mmol L-1) and two levels of iodine (0 and 10 mg L-1). The analyses of variance showed the impact of the main factors (cultivars, NaCl and I) and the interaction between them. The application of iodine on fig seedlings increased the concentration of chlorophyll a, regardless of the cultivar and the concentration of NaCl. The number of new leaves and their dry weight were affected by the interaction between NaCl and I, these variables increased with the presence of I in saline condition. The relative content of total phenols, total flavonoids, antioxidant capacity by DPPH and photosynthetic pigments (chlorophylls and carotenoids) showed interaction between the cultivars, the levels of NaCl and the concentration of I, where the values of these variables were increased by the presence of I under salinity conditions. Due to the above, iodine could be considered as an alternative to mitigate the stress caused by NaCl in Ficus carica L. plants.
Resumen El yodo (I) es un elemento no esencial para las plantas; sin embargo, la aplicación del elemento ha demostrado efectos positivos en plantas cultivadas en condiciones óptimas o bajo estrés. El objetivo de este experimento fue evaluar el impacto del yodo sobre la concentración de compuestos fenólicos, capacidad antioxidante y pigmentos fotosintéticos en hojas de tres cultivares de higuera sometidas a estrés salino. Plantas de higuera de ocho meses de edad fueron establecidas bajo un diseño experimental completamente al azar con arreglo factorial 3x2x2: tres cultivares de higuera (Ficus carica L.): Brown Turkey, Kadota y Black Mission; dos niveles de NaCl (0 y 100 mmol L-1) y dos niveles de yodo (0 y 10 mg L-1). Los análisis de varianza mostraron impacto de los factores (cultivares, NaCl y I) y la interacción entre ellos. La aplicación de yodo en plántulas de higuera incrementó la concentración de clorofila a, independiente del cultivar y la concentración de NaCl. El número de hojas nuevas y el peso seco fue impactado por la interacción entre NaCl y I, incrementándose estás variables con la presencia de I en condición salina. El contenido relativo de fenoles totales, flavonoides totales, capacidad antioxidante por DPPH y pigmentos fotosintéticos (clorofilas y carotenoides) mostraron interacción entre los cultivares, los niveles de NaCl y la concentración de I, donde los valores de las variables fueron incrementados por la presencia de I en condiciones salinas. Por lo anterior, el I podría considerarse como alternativa para mitigar el estrés provocado por NaCl en plantas de Ficus carica L.

ABSTRACT This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation with disc harrow and two passes (M3) or three passes (M4) of leveling disc harrow, straw incorporation with knife-roller and soybean no-tillage (M5), straw incorporation with knife-roller and two passes (M6) or three passes (M7) of leveling disc harrow, straw incorporation with two passes of knife-roller and two passes (M8) or three passes (M9) of leveling disc harrow. Straw incorporation by knife-roller provided the lowest soil organic matter (SOM) contents due to slow mineralization of fresh straw incorporated shallow into the soil, although SOM increased in the surface layer related to the initial content. Rice-soybean succession yield was more affected by the physical than by the soil chemical properties. The straw incorporation with one pass of knife-roller and two passes of leveling disc harrow (M6) can replace the straw burning, without affecting the rice-soybean succession yield and soil physical quality, with a reduction in machinery operations, allowing early soil tillage.

RESUMO: O cultivo do cacau tem grande importância socioeconômica mundial. Os amêndoas de cacau são a matéria-prima essencial para a produção de chocolate. A variabilidade do cacaueiro avaliada representa apenas uma pequena fração da diversidade genética existente, principalmente na região amazônica. Além disso, apenas uma pequena parte dessa variabilidade foi explorada no melhoramento de cacau. Dessa forma, o presente estudo teve como objetivo realizar a avaliação genética e seleção de clones de cacau, com base em características morfo-agronômicas. Para isso, foram avaliados 145 clones, durante 37 colheitas, em quatro anos consecutivos. As seguintes características de frutos e sementes foram avaliadas: número total de frutos colhidos (NTFC), número total de frutos sadios (NTFS), peso de sementes úmidas dos frutos sadios (PSUFS), peso médio de sementes úmidas dos frutos sadios (PMSUFS), peso de sementes secas dos frutos sadios (PSSFS), peso médio de sementes secas dos frutos sadios (PMSSFS), porcentagem de frutos com vassoura-de-bruxa (PFVB), porcentagem de frutos com broca (PFBR), porcentagem de frutos com sementes germinadas (PFSG), número de ramos com vassoura-de-bruxa (NRVB) e número de almofadas florais com vassoura-de-bruxa (NAFVB). Diferenças significativas (P < 0,05) entre os clones foram observadas para todas as características, o que revela uma expressiva variabilidade e possibilidade de ganhos com a seleção. As maiores correlações significativas (P < 0,05) ocorreram entre os caracteres NTFC e NTFS (0,94), NTFS e PMSUFS (0,86) e, NTFS e PMSSFS (0,86).

ABSTRACT: The cultivation of cocoa is of great socio-economic importance worldwide. Cocoa beans are the essential raw material for chocolate production. The variability of cacao studied presents only a small fraction of the existing genetic diversity, mainly in the Amazon region. Furthermore, just a small part of this variability has been exploited in cocoa breeding. Thus, the present study processed the genetic evaluation and selection of cocoa clones, based on morpho-agronomical traits. For this, we evaluated 145 clones, during 37 harvests from, four consecutive years. The following traits were evaluated: total number of fruits collected (TNFC), total number of healthy fruits (TNHF), weight of wet seeds from healthy fruits (WWSHF), average weight of wet seeds per healthy fruit (AWWSHF), weight of dry seeds from healthy fruit (WDSHF), average weight of dry seeds per healthy fruit (AWDSHF), percentage of fruits with witches’ broom disease (PFWB), percentage of fruits with borer (PFBR), percentage of fruits with germinated seeds (PFGS), number of branches with witches’ broom disease (NBWB), and number of inflorescence with witches’ broom disease (NIWB). Significant differences (P < 0.05) among the clones were observed for all traits, which reveal an expressive variability and possibility of gains with selection. The highest significant correlations (P < 0.05) occurred between traits TNFC and TNHF (0.94), TNHF and AWWSHF (0.86), and TNHF and AWDSHF (0.86). Based on the selection index, the clones POUND 12 and CAB 12, 228, 253, 257, 258, and 422 were the most suitable for selection.

ABSTRACT Tomato is one of the most important crops worldwide. Bacterial wilt (BW), caused by Ralstonia spp., is a major disease for tomato production around the world, especially in tropical and subtropical regions. Currently in Brazil, only commercial hybrids are available as resistant rootstocks for use in infested areas, and we lack information regarding resistance to aggressive strains. Thus, the aims of this work were to estimate combining abilities of five tomato inbred lines and hybrids and to identify resistant genotypes for using as rootstocks resistant to Ralstonia solanacearum biovar 2, phylotype II, one of the most aggressive strains in Brazil. Combining abilities for BW resistance were assessed through full diallel crossings among five tomato inbred lines without reciprocals. The experiment was carried out in a greenhouse, in a complete randomized blocks design, using 15 genotypes (hybrids and parents). Additive genetic effects showed to be the most important for controlling bacterial wilt. The inbred line Hawaii 7996 exhibited the highest general combining ability among the five parents assessed. The hybrid Hawaii 7996 × Rodade was the best crossing in terms of resistance and specific combining ability, which was greater than those of all other hybrids. Although Hawaii 7996 remains as a major source for BW resistance, further researches are needed to better understand the resistance dynamics, seeking to develop hybrids with transgressive segregations and more stable resistance against aggressive strains and thrive under environmental conditions highly favorable to bacterial wilt infection.

ABSTRACT Corn is one of the most economically important cereals in the world, ranking second after wheat. Among the great diversity of varieties of Zea mays L. that are cultivated in Cuba, is the "Tayuyo" variety. Currently, there are no studies that evaluate the effect of the salinity of this variety. Therefore, the objective of the present work was to evaluate the effect of saline stress on the growth of seedlings of maize variety "Tayuyo" under in vitro conditions. It was carried out at the Plant Tissue Cultivation Laboratory belonging to the Center for Plant Biotechnology Studies (CEBVEG) of the Faculty of Agricultural Sciences (FCA) of the University of Granma (UDG), Cuba. In which the range of tolerance to salinity of corn plants was evaluated in vitro using a basal culture medium (6 % agar and distilled water) with different levels of electrical conductivity (0, 2, 4, 6 and 8 dS m-1) adjusted with the NaCl reagent. For this research, an experimental design of random blocks was used with three replications where they evaluated; germination percentage, number of roots, length of the primary root, plant height, number of leaves per plant, weight of fresh matter and the index of tolerance to salinity was calculated. The results revealed that the evaluated plants are tolerant to salinity up to 2 dS m-1. In general, the increase in salinity levels caused a delay in germination but not in the germination percentage at eight days after sowing. On the other hand, the rest of the variables showed a downward trend with increasing salinity levels.
RESUMEN El maíz es uno de los cereales de mayor importancia económica en el mundo, ocupando el segundo lugar después del trigo. Entre la gran diversidad de variedades de Zea mays L. que se cultivan en Cuba, se encuentra la variedad “Tayuyo”. En la actualidad no existen estudios que evalúen el efecto de la salinidad de dicha variedad. Por ello el objetivo del presente trabajo fue evaluar el efecto del estrés salino sobre el crecimiento de plántulas de maíz variedad “Tayuyo” en condiciones in vitro. La misma que se llevó a cabo en el Laboratorio de Cultivo de Tejidos Vegetales perteneciente al Centro de Estudios de Biotecnología Vegetal (CEBVEG) de la Facultad de Ciencias Agrícolas (FCA) de la Universidad de Granma (UDG), Cuba. En el cual se evaluó in vitro el rango de tolerancia a la salinidad de plantas de maíz utilizando un medio de cultivo basal (agar al 6 % y agua destilada) con diferentes niveles de conductividad eléctrica (0, 2, 4, 6 y 8 dS m-1) ajustada con el reactivo de NaCl. Para esta investigación se utilizó un diseño experimental de bloques al azar con tres réplicas donde evaluaron; porcentaje de germinación, número de raíces, longitud de la raíz primaria, altura de planta, número de hojas por planta, peso materia fresca y se calculó el índice de tolerancia a la salinidad. Los resultados revelaron que las plantas evaluadas son tolerantes a la salinidad hasta 2 dS m-1 En general el incremento de los niveles de salinidad causó un retardo de la germinación, pero no en el porcentaje de germinación a los ocho días después de la siembra. Por otro lado, el resto de las variables mostraron una tendencia a la disminución con el incremento de los niveles de salinidad.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Abstract Introduction: Sampling by fixed area plots is the usual practice in forest inventories, despite the considerable time involved. An alternative method of sampling is the angle count or Bitterlich method. Objective: To evaluate the accuracy and efficiency of the angle sampling method for the determination of dasometric variables in teak (Tectona grandis L. f.) plantations. Materials and methods: In a three-year teak plantation, 21 circular plots of 500 m2 were established. In each plot, the diameter at breast height, the height and position of each tree, the working times, the number of trees per hectare, the diameter of the average basal area, the total basal area, the average Lorey height and the total volume were determined. Angular sampling was simulated using basal area factors (BAF) of 0.5, 1, 1.5 and 2. The estimates of the variables for each BAF and fixed area plots were compared using ANOVA and the relative efficiency was determined. Results and discussion: The ANOVA did not detect significant differences (P > 0.05) in the estimation of dasometric variables between sampling types, which demonstrates that the angular method is accurate. The fixed area and shape plot required more working time (P < 0.05). The relative efficiency of the angular method was between 4.5 and 11 times higher than that of fixed area plot. The ideal BAF in young teak plantations was equal to two. Conclusions: Angular counting is accurate and more efficient for estimating dasometric variables in young teak plantations.
Resumen Introducción: El muestreo mediante parcelas de superficie fija es la práctica usual en inventarios forestales, a pesar del tiempo considerable de trabajo. Un método alternativo de muestreo es el conteo angular o método de Bitterlich. Objetivo: Evaluar la precisión y eficiencia del método de muestreo angular para la determinación de variables dasométricas en plantaciones de teca (Tectona grandis L. f.). Materiales y métodos: En una plantación de teca de tres años se establecieron 21 parcelas circulares de 500 m2. En cada parcela se determinó el diámetro a la altura del pecho, la altura y posición de cada árbol, los tiempos de trabajo, el número de árboles por hectárea, diámetro de área basal media, área basal total, altura promedio de Lorey y volumen total. El muestreo angular se simuló utilizando factores de área basimétrica (FAB) de 0.5, 1, 1.5 y 2. Las estimaciones de las variables para cada FAB y parcelas de área fija se contrastaron mediante ANOVA y se determinó la eficiencia relativa. Resultados y discusión: El ANOVA no detectó diferencias significativas (P > 0.05) en la estimación de variables dasométricas entre tipos de muestreo, lo cual demuestra que el método angular es preciso. La parcela de área y forma fijas requirió más tiempo de trabajo (P < 0.05). La eficiencia relativa del método angular fue entre 4.5 y 11 veces mayor que la de parcela de área fija. El FAB idóneo en plantaciones jóvenes de teca fue igual a dos. Conclusiones: El conteo angular es preciso y más eficiente para la estimación de variables dasométricas en plantaciones jóvenes de teca.
