ABSTRACT

RESUMEN Por su alto valor nutricional, el frijol común (Phaseolus vulgaris L.) es la especie más importante para el consumo humano entre las leguminosas de grano comestibles. El objetivo de este estudio fue caracterizar 11 líneas RAZ de frijol común, promisorias por su resistencia contra Zabrotes subfasciatus Boh. En octubre de 2019, se sembraron 11 líneas RAZ del Centro Internacional de Agricultura Tropical (CIAT), utilizando un diseño de bloques completos al azar en el Instituto Nacional de Ciencias Agrícolas (INCA), San José de Las Lajas, Cuba. Se evaluaron 22 caracteres cuantitativos y cualitativos del descriptor del frijol común y se realizaron análisis de frecuencia para las características cualitativas y estadígrafos básicos y análisis de componentes principales (ACP) de los atributos cuantitativos. Los caracteres con mayor variabilidad fueron el color primario de la semilla (reportándose 5 diferentes, y siendo el blanco sucio el más frecuente); el color predominante de la vaina en la madurez fisiológica (las cuales presentaron 4 variantes de color, principalmente verdes y amarillas); el aspecto de la testa (destacando el aspecto opaco, registrándose en 6 líneas); así como la ausencia del color alrededor del hilo en 10 de ellas. Los parámetros relacionados con el ciclo biológico presentaron menor variabilidad. El peso de 100 granos correspondió al tipo de grano pequeño. El rendimiento promedio fue 1 685 kg/ha, destacándose la línea 'RAZ 124' con 4 237 kg/ha. El ACP explicó el 61.82 % de la variabilidad total e integró las 11 líneas en 4 grupos que caracterizaron su comportamiento. Los resultados indican que las líneas estudiadas pueden incorporarse en el programa de mejoramiento del frijol en Cuba a través de su evaluación en diferentes ambientes regionales para la selección de posibles nuevos cultivares comerciales.


ABSTRACT Due to high nutritional value, common bean (Phaseolus vulgaris L.) is the most important species for human consumption among the food grain legumes. The objective of this study was to characterize 11 RAZ lines of common bean, promising for their resistance to the Mexican bean weevil (Zabrotes subfasciatus Boh.). In October 2019, 11 RAZ lines from the International Center for Tropical Agriculture (CIAT) were planted using a randomized complete block design at the National Institute of Agricultural Sciences (INCA), San José de las Lajas, Cuba. Twenty-two quantitative and qualitative traits of the common bean descriptors were used, and frequency analyses were performed for the qualitative traits and basic statistics and principal component analysis (PCA) were performed for the quantitative traits. The traits with greater variability were the primary seed color (5 different colors were reported, with dirty white being the most frequent); the predominant color of the pods at physiological maturity, (which presented 4 color variants, with green and yellow ones standing out); the opaque aspect of the coat stood out, being registered in 6 lines, as well as the absence of color around the hilum in 10 of them. All possible variants were found for the predominant appearance of the seed coat, predominant pro-file of the pod and presence of color around the hilum. Variables related to the biological cycle showed less variability. The weight of 100 grains corresponded to the small grains type. The average yield was 1 685 kg/ha, with the 'RAZ 124' line standing out with 4 237 kg/ha. The PCA explained 61.82 % of total variability and classified the 11 lines into four groups that characterize their performance. These results indicate that the lines under study can be incorporated into the vean breeding program in Cuba by means of their evaluation in different regional environments for the selection of possible new commercial cultivars.

ABSTRACT

ABSTRACT In order to increase the efficiency of maize hybrid seed production it is necessary to achieve a high grain yield to reduce production costs. This goal requires an expansion of the basic knowledge of the inheritance of characters in order to develop new breeding techniques to improve experimental materials with hard endosperm (flint). The balanced lethal system allows to study the relative contribution of different chromosome segments to hybrid vigour due to the heterozygosity of certain chromosome segments while the rest of the genome becomes homocygotic through continuous selfing. In this way, these segments can be transferred to inbred lines in order to increase grain yield or tassel size (to increase pollen production). The goal of this study was to transfer a heterotic segment by using a balanced lethal system regulated line (BLS14), through crosses and backcrosses, to S5 flint lines derived from two commercial hybrids, ACA 2000 and Cóndor with closed pedigree, with the objective of increase grain yield or tassel size for pollen production. The analysis of variance (ANOVA) and principal components analysis (PCA) showed a significant improvement in grain yield and tassel size in the S5 flint lines of both commercial hybrids, carrying the heterotic segment of the BLS14 line.


RESUMEN Para incrementar la eficiencia en la producción de semillas híbridas en maíz se necesitan altos rendimientos con un correlativo bajo costo de producción. Esto requiere una expansión de los conocimientos básicos de la herencia de caracteres que posibiliten desarrollar nuevas técnicas de mejoramiento sobre materiales experimentales de textura dura (flint). Los sistemas de letales balanceados permiten estudiar la contribución relativa de distintos segmentos heteróticos en el vigor híbrido dado que permiten lograr la heterocigosis cuasipermanente de una porción del genomio, mientras el resto del genoma se vuelve homocigota por autofecundaciones sucesivas. Estos sistemas pueden ser transferidos a líneas endocriadas para incrementar el rendimiento del grano y el tamaño de la panoja para aumentar la producción de polen. El objetivo de este trabajo fue incorporar un segmento heterótico de una línea regulada por un sistema de letales balanceados (BLS14), mediante cruzamiento y retrocruza, a líneas S5 derivadas de dos híbridos comerciales, ACA 2000 y Cóndor, de pedigree cerrado, con textura dura (flint), con la finalidad de aumentar el rendimiento en grano o el tamaño de la panoja para la producción de polen. Los análisis de variancia (ANOVA) y de componentes principales (ACP) mostraron un incremento significativo en el rendimiento del grano y el tamaño de la panoja de las líneas S5 de ambos híbridos comerciales, portando cada una de ellas el segmento heterótico proveniente de la línea BLS14.

ABSTRACT

Resumen Tenosinovitis es la inflamación o infección de un tendón y su vaina sinovial. Una de las causas puede ser bacteriana. Los gérmenes comunes son los más frecuentes, pero deben investigarse también las micobacterias. En la Argentina, la tuberculosis es un problema de salud pública. Mycobacterium bovis ocasiona zoonosis que afectan animales y humanos. La infección en el hombre se da por inhalación de aerosoles de ganado enfermo, por vía digestiva o cutánea. Las manifestaciones extrapulmonares pueden ser digestivas, ganglionares, cutáneas u osteoarticulares. La tenosinovitis tuberculosa de muñeca es infrecuente y, generalmente, es diagnosticada como tenosinovitis reumática o inespecífica. Se presenta el caso de una mujer de 48 años, residente de zona rural, que presentaba hipertrofia y edema en dedos de la mano izquierda. Se le realizó cirugía del túnel carpiano y se observaron cuerpos como granos de arroz. Del tejido sinovial se aisló M. bovis. Comenzó tratamiento tuberculostático más claritromicina. Evolucionó favorablemente.


Abstract Tenosynovitis is an inflammation or infection of a tendon and its synovial sheath. One cause of this illness may be bacterial, being common organisms more frequent, but mycobacteria should be also investigated. In Argentina, tuberculosis is a public health problem. Mycobacterium bovis causes zoonoses that affect animals and humans. Infection in man occurs by inhalation of aerosols from sick cattle, by digestive or cutaneous routes. Extrapulmonary manifestations can be digestive, nodal, cutaneous or osteoarticular. Tuberculous wrist tenosynovitis is uncommon, usually diagnosed as rheumatic or nonspecific tenosynovitis. The case of a 48-year-old woman, a resident of rural areas, presenting hypertrophy, and edema in the fingers of the left hand was introduced. Carpal tunnel surgery was performed, while rice grain bodies were noticed. Synovial tissue material was taken for mycobacterial culture, where M. bovis was isolated. She began tuberculostatic treatment plus clarithromycin. She evolved favourably.


Resumo A tenossinovite é a inflamação ou infecção de um tendão e sua bainha sinovial. A causa pode ser bacteriana, sendo os germes comuns os mais frequentes, mas as micobactérias devem ser investigadas. Na Argentina, a tuberculose é um problema de saúde pública. Mycobacterium bovis causa zoonose que afeta animais e humanos. A infecção no homem ocorre por inalação de aerossóis de gado doente, por via digestiva ou cutânea. As manifestações extrapulmonares podem ser digestivas, ganglionares, cutâneas, osteoarticulares. A tenossinovite tuberculosa do pulso é pouco frequente, geralmente diagnosticada como tenossinovite reumática ou inespecífica. Apresenta-se o caso de uma mulher de 48 anos, moradora de zona rural, com hipertrofia e edema nos dedos da mão esquerda. Foi realizada cirurgia do túnel do carpo, observando-se corpos como grãos de arroz. Do tecido sinovial foi isolado M. bovis. Iniciou-se tratamento tuberculostático mais claritromicina.

ABSTRACT

Background: Brewer ́s spent grain (BSG) is a biomass by-product generated in large volumes during industrial beer production. BSG has become a growing environmental problem, as most breweries discard it inappropriately, negatively impacting the environment. Alternatives for the exploitation of this by-product have consisted of elaborating food supplements for farm animals, obtaining biofuels, developing adsorbents, and obtaining substances for the food industry. However, the high moisture content in BSG (approximately 70%), poses a significant challenge in exploring various reuse alternatives. Therefore, the implementation of a pre-drying process becomes essential. Objective: This study aimed to analyze the BSG drying kinetics at different temperatures and the effect of the drying temperature on the physical properties and the content of bioactive compounds. Methods: BSG samples were dried at different temperatures (50, 60, 70, 80, 90, and 105°C) and analyzed for their moisture ratio, water activity, total polyphenol content (TPC), and DPPH (1,1-diphenyl-2-picrylhydrazil) radical scavenging activity. Also, four kinetics models were fitted to the drying data. Results:It was determined that the effective diffusivity was between 5.23x10


Antecedentes: El Bagazo residual de malta (BSG por sus siglas en inglés) es un subproducto biomásico generado en grandes volúmenes durante la producción industrial de cerveza. El BSG se ha convertido en un creciente problema para el medio ambiente, debido a que la mayoría de las cervecerías descartan inapropiadamente este residuo generando un impacto negativo al ambiente. Las alternativas para el aprovechamiento de este subproducto han consistido especialmente en la elaboración de suplementos alimenticios para animales de granja, obtención de biocombustibles, desarrollo de adsorbentes y obtención de productos para la industria alimentaria. Sin embargo, el alto contenido de humedad (~70%) del BSG representa un reto para el desarrollo de diferentes alternativas de reutilización, por lo que se hace necesario un proceso de secado previo. Objetivos: En este estudio se analizó la cinética de secado del BSG a diferentes temperaturas y el efecto de la temperatura de secado sobre sus propiedades físicas y contenido de compuestos bioactivos. Métodos: Las muestras de BSG fueron secadas a diferentes temperaturas (50, 60, 70, 80, 90 y 105°C) y analizadas en términos de razón de humedad, actividad acuosa, contenido de polifenoles totales (TPC) y actividad secuestradora del radical DPPH. Además, se ajustaron 4 modelos cinéticos a los datos de secado. Resultados: Se determinó que la difusividad efectiva del BSG varió entre 5.23x10

ABSTRACT

OBJECTIVE@#To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6) on Wnt/β-catenin signaling pathway in bone marrow cell in mice with bone marrow inhibition, and to explore the possible mechanism of wheat-grain moxibustion in treating bone marrow inhibition.@*METHODS@#Forty-five SPF male CD1(ICR) mice were randomly divided into a blank group, a model group and a wheat-grain moxibustion group, 15 mice in each group. The bone marrow inhibition model was established by intraperitoneal injection of 80 mg/kg of cyclophosphamide (CTX). The mice in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14), "Zusanli" (ST 36) and "Sanyinjiao" (SP 6), 3 moxa cones per acupoint, 30 s per moxa cone, once a day, for 7 consecutive days. The white blood cell count (WBC) was measured before modeling, before intervention and 3, 5 d and 7 d into intervention. After intervention, the general situation of mice was observed; the number of nucleated cells in bone marrow was detected; the serum levels of interleukin-3 (IL-3), interleukin-6 (IL-6) and granulocyte macrophage colony stimulating factor (GM-CSF) were measured by ELISA; the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc in bone marrow cells was measured by Western blot and real-time PCR method.@*RESULTS@#Compared with the blank group, the mice in the model group showed sluggish reaction, unstable gait, decreased body weight, and the WBC, number of nucleated cells in bone marrow as well as serum levels of IL-3, IL-6, GM-CSF were decreased (P<0.01), and the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc was decreased (P<0.01). Compared with the model group, the mice in the wheat-grain moxibustion group showed better general condition, and WBC, the number of nucleated cells in bone marrow as well as serum levels of IL-3, IL-6, GM-CSF were increased (P<0.01, P<0.05), and the protein and mRNA expression of β-catenin, cyclinD1 and C-Myc was increased (P<0.05).@*CONCLUSION@#Wheat-grain moxibustion shows therapeutic effect on bone marrow inhibition, and its mechanism may be related to activating Wnt/β-catenin signaling pathway in bone marrow cells, improving bone medullary hematopoiesis microenvironment and promoting bone marrow cell proliferation.

ABSTRACT

@#Introduction: Barnyard millet, an ancient grain that serves as a staple food and a key component of many diets, requires processing before consumption. Roasting is a common processing method that can enhance millet palatability. However, it is important to ensure that the nutritional properties are well preserved. Hence, this study investigated the influence of roasting on the proximate composition, amino acid composition, total phenolic content (TPC) and antioxidant activity of the whole grain barnyard millet sample. Method: The roasted sample of whole grain barnyard millet was roasted in the oven at 110℃ for 10 minutes and used for proximate analysis and amino acid composition. Meanwhile, TPC and DPPH were performed using the ethanol extract of a roasted whole-grain barnyard millet sample. Results: This study found a significant (p<0.05) of 14.22% reduction in moisture content in roasted millet compared to non-roasted millet. The roasted millet sample showed a higher fat content (p<0.05) compared to the non-roasted millet sample, with values of 5.08±0.24% and 4.38±0.24%, respectively. The total amino acid content of the non-roasted sample was 116.76±11.31ng, while the roasted sample had a value of 123.51±0.23.22ng. In addition, the TPC and antioxidant activity were found significantly higher (p<0.05) in the roasted sample than in the non-roasted sample of whole grain barnyard millet. Conclusion: The roasting method should be considered in processing of the whole grain barnyard millet to enhance the nutrient composition and boost its functionality.

ABSTRACT

Quando se trata de milho pipoca o Brasil é o segundo maior produtor, mas necessitando ainda de importações para suprir a demanda interna do país, visto a importância de estudos que melhor explorem as recomendações agronômicas para a cultura do milho pipoca. Assim, o presente estudo objetivou avaliar o impacto da população de plantas sobre algumas variáveis morfológicas e na produtividade final de grãos de dois híbridos de milho pipoca (8203 e 4512). Foram estudadas as populações de 60.000, 65.000, 70.000, 75.000 e 80.000 plantas por ha-1 no espaçamento de 0,45cm entre linha de semeadura. O experimento foi conduzido no ano agrícola 2018/2019, na área experimental do Departamento de Ciências Agronômicas e Ambientais da Universidade Federal de Santa Maria, campus Frederico Westphalen ­ RS, em um delineamento de blocos casualizados em um esquema fatorial (2x5). O diâmetro de colmo, comprimento da espiga e peso de mil sementes diminuíram à medida que se aumentou a população de plantas. Para ambos os híbridos, e para a maioria das variáveis analisadas as densidades populacionais não interferiram de forma significativa na produtividade final de grãos do milho pipoca. Entretanto quando se trabalha a média das populações se observa uma superioridade do híbrido 8203 para as variáveis, altura de planta, altura de inserção da espiga, prolificidade, empalhamento, diâmetro de espiga, número de grãos por espiga, peso de mil sementes e produtividade final de grãos.(AU)


When it comes to popcorn, Brazil is the second largest producer, but still needing imports to supply the country's domestic demand, given the importance of studies that better explore agronomic recommendations for popcorn culture. Thus, the aim of the present study was to evaluate the impact of the plant population on some morphological variables and the final consumption of two hybrid popcorn kernels (8203 and 4512). The populations of 60.000, 65.000, 70.000, 75.000 and 80.000 plants per ha-1 were studied in the 0.45cm spacing between sowing lines. The experiment was carried out in the agricultural year 2018/2019, in the experimental area of the Department of Agricultural and Environmental Sciences of the Federal University of Santa Maria, Frederico Westphalen campus - RS, in a randomized block design in a factorial scheme (2x5). The stem diameter, ear length and weight of a thousand seeds decreased as the plant population increased. For both hybrids, and for most of the variables analyzed, population densities did not significantly affect the final grain yield of popcorn. However, when working with the average population, a superiority of the 8203 hybrid is observed for the variables, plant height, height of ear insertion, prolificacy, stuffing, ear diameter, number of grains per ear, weight of a thousand seeds and final productivity of grain.(AU)


En lo que respecta a las palomitas de maíz, Brasil es el segundo mayor productor, pero aún necesita importaciones para satisfacer la demanda interna del país, dada la importancia de los estudios que exploran mejor las recomendaciones agronómicas para el cultivo de palomitas de maíz. Por lo tanto, el objetivo del presente estudio fue evaluar el impacto de la población de plantas en algunas variables morfológicas y en el rendimiento final de grano de dos híbridos de palomitas de maíz (8203 y 4512). Se estudiaron las poblaciones de 60.000, 65.000, 70.000, 75.000 y 80.000 plantas por ha-1 en el espacio de 0.45cm entre líneas de siembra. El experimento se realizó en el año agrícola 2018/2019, en el área experimental del Departamento de Ciencias Agronómicas y Ambientales de la Universidad Federal de Santa María, campus Frederico Westphalen - RS, en un diseño de bloques al azar en un esquema factorial (2x5). El diámetro del tallo, la longitud de la mazorca y el peso de mil semillas disminuyeron à medida que aumentó la población de plantas. Para ambos híbridos, y para la mayoría de las variables analizadas, las densidades de población no afectaron significativamente el rendimiento final de grano de las palomitas de maíz. Sin embargo, cuando se trabaja con la población promedio, se observa una superioridad del híbrido 8203 para las variables, altura de la planta, altura de inserción de la mazorca, prolificidad, relleno, diámetro de la mazorca, número de granos por mazorca, peso de mil semillas y productividad final de grano.(AU)

ABSTRACT

Aim: This study was conducted to determine the relationship between carbohydrate quality and sleep quality, depression, anxiety, stress and anthropometric measurements. Methods: The carbohydrate quality was calculated using the total fiber intake, ratio of whole grains to total grains, the ratio of solid carbohydrates to total carbohydrates, and the glycemic index. Sleep status was determined using the Pittsburgh Sleep Quality Index (PSQI) and nutritional status was determined by taking a 1-day food consumption record and food consumption frequency. Results: It was found that 20% of the participants with the highest carbohydrate quality had the highest sleep quality and the lowest body mass index. Conclusion: Adults should be informed that the quality of carbohydrates that they consume, was associated with better sleep quality and some micronutrients (potassium, magnesium, vitamin A-D-K-C-B1-B6, Folate) but no significant correlation was found between anxiety, depression, and stress scores


Objetivos: Este estudio se realizó para determinar la relación entre la calidad de los carbohidratos y la calidad del sueño, la depresión, la ansiedad, el estrés y las medidas antropométricas. Métodos: La calidad de los carbohidratos se calculó utilizando la ingesta total de fibra, la proporción de granos integrales a granos totales, la proporción de carbohidratos sólidos a carbohidratos totales y el índice glucémico. El estado del sueño se determinó utilizando el índice de calidad del sueño de Pittsburgh (PSQI) y el estado nutricional se determinó tomando un registro de consumo de alimentos de un día y la frecuencia de consumo de alimentos. Resultados: Se encontró que el 20% de los participantes con la mayor calidad de carbohidratos tenían la mejor calidad de sueño y el índice de masa corporal más bajo. Conclusión: Se debe informar a los adultos que la calidad de los carbohidratos que consumen, se asoció con una mejor calidad del sueño y algunos micronutrientes (potasio, magnesio, vitamina A-D-K-C-B1-B6, folato), pero no se encontró una correlación significativa entre las puntuaciones de ansiedad, depresión y estrés.

ABSTRACT

Background: Corn is, quantitatively, one of the most important world crops (ranking second only after wheat) and a key ingredient in animal feeds. Objective: to assess and compare corn quality, mycotoxin content, chemical composition and apparent metabolizable energy (AME) of domestic and imported corn. Methods: Grain quality (USDA grading system) was determined in 30 samples of domestic and 21 samples of imported corn. From each origin, 15 samples were subjected to proximal analysis and 10 were used to determine fatty acid composition. Mycotoxin analysis was conducted on 30 samples of domestic and 23 of imported corn. Results: six of the 30 domestic samples corresponded to US1 grade (highest quality) vs. none of the imported. In the "sample grade" category (lowest quality), 10 and 6 samples corresponded to imported and domestic corn, respectively. Soybeans were found as contaminant in 15 of the 21 imported corn samples. Aspergillus spp. mycotoxins such as ochratoxin A were not detected, and aflatoxins were found in only a few samples at very low levels. Fusariotoxins such as deoxynivalenol and zearalenone were found in 61 and 43% of imported samples, respectively, but in none of the domestic samples. Domestic corn had lower carbohydrate content compared with imported corn (85.4 vs. 86.7%), but higher crude fat (3.8 vs. 3.1%). The AME values for domestic and imported corn were 3,697 and 3,378 kcal/kg, respectively. The fatty acid profiles from both corn types were similar. Conclusion: This study found significant differences between locally-grown and imported corn, particularly in terms of crude fat, AME content, fusariotoxins, and contaminant seeds (soybeans). These findings suggest that locally-grown corn might have nutritional and toxicological advantages over corn imported from the United States.


Antecedentes: El maíz es, cuantitativamente, uno de los cultivos más importantes a nivel mundial (ocupa el segundo lugar después del trigo) y uno de los principales ingredientes en dietas para animales. Objetivo: Evaluar y comparar la calidad del maíz, su contenido de micotoxinas, composición química, y energía metabolizable aparente (AME) del maíz nacional e importado. Métodos: La calidad del grano (sistema de clasificación de la USDA) se determinó en 30 muestras de maíz producido en Colombia y 21 de maíz importado. De cada origen, 15 muestras se sometieron a análisis proximal y 10 se analizaron para determinar el perfil de ácidos grasos. El contenido de micotoxinas se determinó en 30 muestras de maíz nacional y 23 de maíz importado. Resultados: Seis de las treinta muestras nacionales analizadas para calidad de grano correspondieron a grado US1 (la mejor calidad) frente a ninguna de las importadas. En categoría "grado muestra" (la menor calidad) se encontraron 10 y 6 de las muestras de maíz importado y nacional, respectivamente; 15 de las 21 muestras de maíz importado presentaron contaminación con semillas de fríjol soya. No se encontraron micotoxinas de hongos Aspergillus spp. (ocratoxina A), y niveles muy bajos de aflatoxinas en unas pocas muestras. Fusariotoxinas tales como deoxinivalenol y zearalenona se detectaron en el 61 y 43% de las muestras de maíz importado, respectivamente, pero en ninguna muestra de maíz nacional. El maíz nacional presentó menor contenido de carbohidratos (85,4 vs. 86,7%), pero mayor contenido de grasa cruda (3,8 vs. 3,1%) en comparación con el importado, respectivamente. Los valores de AME fueron de 3.697 y 3.378 kcal/kg para el maíz nacional e importado, respectivamente. El perfil de ácidos grasos de ambas procedencias fue similar. Conclusiones: Este estudio encontró diferencias significativas entre el maíz de producción nacional y el importado, en especial en su contenido de grasa cruda y AME, fusariotoxinas, y semillas contaminates (soya). Estos hallazgos sugieren que el maíz de producción nacional puede presentar ventajas de tipo nutricional y toxicológico frente al maíz importado de los Estados Unidos de América.


Antecedentes: O milho é quantitativamente uma das culturas mais importantes em nível mundial (ocupando o segundo lugar depois do trigo), sendo um dos principais ingredientes em dietas para animais. Objetivo: Avaliar e comparar a qualidade do milho, o teor de micotoxinas, a composição química e a energia metabolizável aparente (EMA) do milho nacional e importado. Métodos: A qualidade do grão (sistema de classificação do USDA) foi determinada em 30 amostras de milho produzido na Colômbia e 21 amostras de milho importado. Quinze amostras de cada tipo de milho foram submetidas a análise proximal e dez amostras de cada milho foram analisadas para determinar o perfil de ácidos graxos. O conteúdo de micotoxinas foi determinado em 30 amostras de milho da Colômbia e em 23 amostras de milho importado. Resultados: Seis das trinta amostras colombianas analisadas para qualidade de grão corresponderam a grau US1 (melhor qualidade) frente a nenhuma das amostras importadas. Na categoria "grau amostra" (menor qualidade) foram encontradas 10 e 6 amostras de milhos importados e colombianos, respectivamente; Quinze das 21 amostras de milho importado apresentaram contaminação com sementes de feijão soja. Não foram encontradas micotoxinas de fungos Aspergillus spp. (ocratoxina A) ou apenas níveis muito baixos em poucas amostras (aflatoxinas). As fusariotoxinas, deoxinivalenol e zearalenona foram detectadas em 61 e 43% das amostras de milho importado, respectivamente, mas não foram detectadas em nenhuma amostra do milho colombiano. O milho colombiano apresentou menor conteúdo de carboidratos (85,4 vs. 86,7%) porém maior conteúdo de gordura crua (3,8 vs. 3,1%). Os valores de AME foram 3.697 e 3.378 kcal/kg para as amostras de milho colombiano e importado, respectivamente. O perfil de ácidos graxos de ambos tipos de milho foi similar. Conclusões: Os resultados do presente estudo mostram diferenças significativas entre o milho de origem colombiana e o milho importado dos Estados Unidos, em especial no conteúdo de gordura crua e AME, fusariotoxinas e sementes contaminantes (soja). Estes achados sugerem que o milho de produção colombiana pode apresentar vantagens de tipo nutricional e toxicológica frente ao milho importado dos Estados Unidos.

ABSTRACT

Harvesting is one of the most important stages of the agricultural production process. However, the lack of monitoring during this operation and the absence of efficient methodologies to quantify losses have contributed to the decline in the quality of the operation. The objective of this study was to monitor mechanized soybean harvest by quantifying losses through two methodologies using statistical process control. The study was conducted in March 2016 in an agricultural area in the municipality of Ribeirão Preto, SP, using a John Deere harvester model 1470 with a tangential-type track system and separation by a straw-blower. The experimental design followed the standards established by statistical process control, and every 8 min of harvest, the total losses by the circular framework and rectangular framework methodologies were simultaneously quantified, totaling 40 points. Data were analyzed using descriptive statistics and statistical process control. The averages of the circular methodology framework were values above those found in the rectangular methodology framework, presenting greater representativeness of losses. The process was considered unable to maintain losses of soybeans at acceptable levels during mechanical harvest throughout the operation of the two frameworks. The circular framework for collecting samples at different locations resulted in higher reliability of data.

ABSTRACT

This study was aimed to investigate the response of some wheat (Triticum aestivum L.) landraces to three irrigation sources, freshwater (FW), well water (WW), and treated municipal wastewater (TMW), regarding the impact on growth, yield, and grains elements contents. The results showed that the various wheat landraces irrigated with treated wastewater were significantly taller (117.3 cm) with multi tillers (22 tiller plant-1), had maximum spikes per plant (2.6), and longer weighty spikes (14.5 cm & 12.1 g). Landraces L1(Burr), L2 (Baldy Burr), C7 (Yecora Rojo), had maximum tillers, L4 (Alssamaa Burr), L5 (Bahaal Burr), L7 (Yecora Rojo) had more spikes per plant and the longer weighty spikes were recorded in L5 Baldy Burr, L1(Burr), heavy spikes were reported in L5 (Bahaal Burr) and L1(Burr). Moreover, these landraces had the highest yield per plant and 1000 grains weight (49.8 g, 12.5 g) respectively. The N, P, K, and Mg contents were increased under TMW, and their levels in landraces and cultivars in order are 3>L2>L4>L5>L1>C6>C7. Even Cu, Fe, Mn, Zn levels were higher in various landraces irrigated with TMW, however, L3, L2, and L4 had maximum contents of all microelements. TMW irrigation enhanced growth, yield, and grain quality in terms of essential elements. The irrigation of landraces L1, L4, L5 with TMW may be a feasible alternative for sustainable wheat production and safe water in arid regions such as Saudi Arabia.

ABSTRACT

OBJECTIVE@#To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14) on the expressions of Beclin-1 and GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy (CSR), and to explore the possible analgesic mechanism of wheat-grain moxibustion for CSR.@*METHODS@#A total of 48 SD rats were randomly divided into a sham operation group, a model group, a wheat-grain moxibustion group and a wheat-grain moxibustion+3-MA group, 12 rats in each group. The CSR model was prepared by spinal cord insertion method. Three days after modeling, the rats in the model group were intraperitoneally injected with 1 mL of 0.9% sodium chloride solution; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time) on the basis of the model group; the rats in the wheat-grain moxibustion+3-MA group were intraperitoneally injected with 3-MA solution and wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time). The three groups were intervened for 7 days, once a day. The gait score and mechanical pain threshold were observed before treatment and 7 days into treatment; after the treatment, the expressions of mRNA and protein of Beclin-1 in spinal dorsal horn were detected by real-time fluorescence quantitative PCR and immunohistochemistry; the expression of GRP78 protein in spinal dorsal horn was detected by Western blot method; the autophagosomes and ultrastructure in spinal dorsal horn neurons were observed by electron microscope.@*RESULTS@#After the treatment, compared with the sham operation group, in the model group, the gait score was increased and the mechanical pain threshold was decreased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was increased (P<0.01). Compared with the model group and the wheat-grain moxibustion+3-MA group, in the wheat-grain moxibustion group, the gait score was decreased and mechanical pain threshold was increased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was decreased, and the expressions of mRNA and protein of Beclin-1 were increased (P<0.01). Under electron microscope, the ultrastructure of spinal dorsal horn neurons in the wheat-grain moxibustion group was not significantly damaged, and its structure was basically close to normal, and the number of autophagosomes was more than the other three groups.@*CONCLUSION@#Wheat-grain moxibustion at "Dazhui" (GV 14) has analgesic effect on CSR rats. The mechanism may be related to moderately up-regulate the expression of Beclin-1, enhance autophagy and reduce endoplasmic reticulum stress.

ABSTRACT

OBJECTIVE@#To observe the effect of wheat-grain moxibustion on behavior, 5-hydroxytryptamine (5-HT) and cortisol in the serum, mineralocorticoid receptor (MR) and glucocorticoid receptor (GR) in the hippocampus in rats with hypothyroidism complicated with depression, and to explore the possible mechanism of wheat-grain moxibustion on improving depression in rats with hypothyroidism.@*METHODS@#A total of 32 SPF SD rats were randomly divided into a blank group, a model group, a medication group and a wheat-grain moxibustion group, 8 rats in each group. Except for the blank group, the rats in the remaining groups were treated with intragastric administration of 0.1% propylthiouracil (PTU) suspension at 1 mL/100 g, once a day for 4 weeks to establish the rat model of hypothyroidism, and whether the rats were accompanied with depression-like behavior determined through behavioristics evaluation. The rats in the medication group were intervened with euthyrox at 0.9 mL/100 g, once a day, for 4 weeks; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14), "Mingmen" (GV 4), "Shenshu" (BL 23) and "Pishu" (BL 20), 7 cones each acupoint, once a day, six times a week for 4 weeks. After the intervention, the depression status was observed by behavioristics test; the contents of thyroid stimulating hormone (TSH), total thyroxine (TT4), 5-HT and cortisol in the serum were detected by ELISA; the protein expressions of MR and GR in hippocampus were detected by Western blot; the expressions of MR mRNA and GR mRNA in the hippocampus were detected by real-time PCR.@*RESULTS@#Before the intervention, compared with the blank group, the scores of open field test (OFT) were decreased and the immobility time of tail suspension test (TST) was prolonged (P<0.05); the serum TSH contents were increased and TT4 contents were decreased (P<0.01) in the other three groups. After the intervention, compared with the model group, the vertical score of OFT was increased and the immobility time of forced swimming test (FST) was prolonged in the medication group (P<0.05), while the scores of three items of OFT were increased (P<0.05, P<0.01), and the immobility time of FST and TST was shortened in the wheat-grain moxibustion group (P<0.01, P<0.05). Compared with the medication group, the immobility time of TST and FST in the wheat-grain moxibustion group was shorter (P<0.05, P<0.01). Compared with the blank group, in the model group, the contents of serum TSH and cortisol were increased (P<0.01, P<0.001), while the contents of serum TT4 and 5-HT were decreased (P<0.01, P<0.001). Compared with the model group, the contents of serum TT4 and 5-HT were increased, while the contents of serum TSH and cortisol were decreased in the medication group and wheat-grain moxibustion group (P<0.01, P<0.05). Compared with the blank group, the protein and mRNA expression of MR, GR in the hippocampus in the model group was decreased (P<0.01, P<0.05, P<0.001); compared with the model group, the protein and mRNA expression of MR in the hippocampus in the medication group were increased (P<0.05), and the protein expression of MR, GR and mRNA expression of MR in the hippocampus in the wheat-grain moxibustion group were increased (P<0.05, P<0.01). Compared with the medication group, the expression of MR mRNA in the wheat-grain moxibustion group was increased (P<0.05).@*CONCLUSION@#Wheat-grain moxibustion could significantly improve thyroid function and depression in rats with hypothyroidism. Its mechanism may be related to up-regulating the protein and mRNA expression of MR and GR in the hippocampus, and then affecting the expression of serum cortisol and 5-HT.

ABSTRACT

OBJECTIVE@#To rank the effectiveness of various moxibustion methods on the quality of life in tumor patients, and explore the best treatment plan of moxibustion for improving the quality of life in tumor patients from the perspective of evidence-based medicine.@*METHODS@#The Chinese and English literature of randomized controlled trial (RCT) of the effect of moxibustion on the quality of life in tumor patients were searched in PubMed, EMbase, Cochrane Library, CNKI, SinoMed, Wanfang and VIP. The retrieval time was from the establishment of the databases to October 31, 2020. The R3.6.2 and Stata15.0 software were used for network Meta-analysis based on Bayesian model.@*RESULTS@#A total of 30 Chinese RCTs were included, including 2 169 patients, involving 16 interventions. In terms of the effectiveness of improving quality of life, the top three treatments were special moxibustion plus other therapies 1 (either of tendon acupuncture, acupoint pressing, acupoint injection, etc.), wheat-grain moxibustion and mild moxibustion. The special moxibustion methods were the combination of fire-dragon moxibustion, thunder-fire moxibustion, fuyang fire moxibustion and moxa salt-bag moxibustion. The number of literature of these four moxibustion methods was small. Considering the clinical application of moxibustion, it was concluded that wheat-grain moxibustion ranked first.@*CONCLUSION@#The adjuvant treatment of wheat-grain moxibustion is more effective than other moxibustion methods on improving the quality of life in tumor patients, but the results needed to be further verified because the bias risk of RCT included in this study is high and the sample size is small.

ABSTRACT

We evaluated the long-term safety of eight adult volunteers (male 7, female 1: average age 47.4 years) ingesting powdered foods containing Coix-seed Reactive Derivatives (CRD/2.2g/day or 4.4g/day) for 1 year 8 months to 5 years (average 2 years 9 months). Body weight, vital signs (blood pressure, pulse rate), peripheral blood test, blood biochemical test, etc. were observed. We also investigated the presence or absence of side effects. The results showed no notable changes in vital signs or blood test results. From the above, it was speculated that long-term intake of CRD would not pose a safety problem. We plan to continue the study by increasing the number of observation cases in the future.

ABSTRACT

Objective: We investigated the effects of Coix-seed Reactive Derivatives (CRD) on fibroblast proliferation and collagen production. Methods: Various concentrations of CRD (0.00001%, 0.0001%, 0.001%, 0.01%, 0.1%, 1%) were added to human fibroblasts, and changes in cell count and extracellular collagen production were measured. Results: Fibroblasts proliferated by the addition of CRD, peaked at about 1.7 times when the CRD concentration was 0.0001%, and then decreased as the addition concentration increased. On the other hand, the collagen concentration in the extracellular matrix of fibroblasts increased as the CRD addition concentration increased, and the collagen concentration increased sharply at 0.1% of CRD concentration or more. Conclusion: It was suggested that CRD has a function of increasing the proliferation of fibroblasts and collagen production.

ABSTRACT

ABSTRACT: Kazakhstan is located in the hinterland of Central Asia. Its virtuous geographical advantages and huge grain production potential make it one of the most important grain exporters in the world. The research on the problem of the grain trade in Kazakhstan is of great significance for food security. This study measured its international competitiveness using the International Market Share Index, the Revealed Comparative Advantage Index, Trade competitiveness index and calculated the international competitiveness and analyzed the influencing factors of grain export by constructing an extended gravity model and measured its export potential. Results showed that Kazakhstan has a low share of the international grain market; however, wheat, barley, and buckwheat have strong export advantages; the level of economic development and economic distance has significantly promoted the scale of grain exports. While geographical distance, the difference in GDP per capita, and the fact whether trading partner countries have joined the Eurasian Economic Union have caused obstacles to grain exports. Kazakhstan's export potential to 6 countries including Russia, Kyrgyzstan and China shows an upward" trend, its export potential to 6 countries including Tajikistan and Ukraine showing a "stable" trend, and its export to 9 countries included Poland and Germany. The potential showed a "declining" trend.


RESUMO: O Cazaquistão está localizado no interior da Ásia Central. Suas virtuosas vantagens geográficas e grande potencial de produção de grãos a tornam um dos exportadores de grãos mais importantes do mundo. A pesquisa sobre o problema do comércio de grãos no Cazaquistão é de grande importância para a segurança alimentar. Este estudo mede sua competitividade internacional por meio do índice IMS, índice RCA, índice TC e calcula a competitividade internacional e analisa os fatores influenciadores da exportação de grãos por meio da construção de um modelo gravimétrico estendido e mede seu potencial exportador. Os resultados mostram que o Cazaquistão tem uma baixa participação no mercado internacional de grãos; no entanto, trigo, cevada e trigo sarraceno têm fortes vantagens de exportação; o nível de desenvolvimento econômico e a distância econômica têm promovido significativamente a escala das exportações de grãos. Embora a distância geográfica, a diferença no PIB per capita e o fato de os países parceiros comerciais terem aderido à União Econômica da Eurásia têm causado obstáculos às exportações de grãos. O potencial de exportação do Cazaquistão para seis países, incluindo Rússia, Quirguistão e China mostra uma tendência de "alta", seu potencial de exportação para seis países, incluindo Tajiquistão e Ucrânia, mostra uma tendência" estável "e sua exportação para nove países, incluindo Polônia e Alemanha. O potencial mostra uma tendência de "declínio".

ABSTRACT

Objective: To investigate whether grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) can alleviate cognitive decline and other pathologic features in early-stage Alzheimer disease (AD) using transgenic mice with 5 familial AD mutations (5XFAD). Methods: The genotype of transgenic mice was detected by polymerase chain reaction. A total of 40 transgenic mice (1.5 months old) were randomly and equally allocated to an AD model group (5XFAD group) or a grain-sized moxibustion group (5XFAD + GM group), with 20 wild-type (WT) mice (C57BL/6J) serving as the normal control group (WT group). Mice in the 5XFAD + GM group were treated by grain-sized moxibustion at bilateral Xinshu (BL15) and Shenshu (BL23). Mice in the WT group and 5XFAD group received no treatment but were restrained to ensure exposure to a similar experimental condition. Cognitive function and memory were assessed with the Morris water maze and Y-maze tests. The amyloid β 40 (Aβ40) and amyloid β 42 (Aβ42) levels in the brain were evaluated by enzyme-linked immunosorbent assay; amyloid plaque deposition in brain tissue sections was detected by thioflavin-S staining; the expression of glial fibrillary acidic protein (GFAP), cluster of differentiation 11b (CD11b), brain-derived neurotrophic factor (BDNF), and choline acetyltransferase (ChAT) in the hippocampus and prefrontal cortex was analyzed by immunohistochemistry. Results: In the Morris water maze test, compared with the 5XFAD group, mice in the 5XFAD + GM group had a shorter escape latency and more target area crossings and spent more time in the target quadrant (P<0.05). In the Y-maze test, compared with the 5XFAD group, the number of training times of the 5XFAD + GM group was significantly decreased (P<0.05), together with more correct responses (P<0.05). Compared with the 5XFAD group, the levels of Aβ40 and Aβ42 in the brain tissue of the 5XFAD + GM group were significantly lower (P<0.05); in the hippocampus and prefrontal cortex, the total number of amyloid β plaque deposition were significantly lower (P<0.05); the expression levels of GFAP and CD11b were significantly reduced (P<0.05); and the expression levels of ChAT and BDNF were significantly increased (P<0.05).Conclusion: Grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) greatly improves learning and memory functions, decreases the levels of Aβ40 and Aβ42, inhibits amyloid β plaque deposition, decreases the expression of GFAP and CD11b, and increases the expression of ChAT and BDNF in AD mice to inhibit the progression of AD.

ABSTRACT

This study was aimed to evaluate and compare the nutrient digestibility of grain-inclusive and grain-free commercial dry dog foods using the method of total fecal collection and also explore their effects on fecal consistency. 21 different foods, including 14 grain-inclusive (7 grain-chicken meat, 7 grain-lamb meat) and 7 grain-free were investigated. 12 adult Golden retriever dogs (age 3-4 years, body weight=22.5±1.7kg) were divided into 3 groups. The results of digestibility trials indicated that the grain-lamb meat foods showed the highest digestibility of dry matter, organic matter, and crude fiber. Overall, in the grain-inclusive and grain-free group evaluation, grain-inclusive foods showed higher digestibility of crude fibers while grain-free foods had higher ether extract digestibility whereas the differences in the scores of fecal consistencies between the groups were insignificant. Contrary to popular belief, grain-inclusive foods were more digestive than grain-free foods in terms of dry matter and organic matter. There are studies involving starch sources in the dog food formulations, but there is a need to study the digestibility of complete dog food to supply them with adequate nutrients. Also, each diet should be assessed based on its overall nutrient profile and digestibility rather than individual ingredients.(AU)


Este estudo teve como objetivo avaliar e comparar as digestibilidades de nutrientes de alimentos secos para cães comerciais, com grãos e livres de grãos, usando o método de coleta fecal total, bem como explorar seus efeitos na consistência fecal. Vinte e um alimentos diferentes, incluindo 14 grãos inclusivos (sete grãos de carne de frango, sete grãos de carne de cordeiro) e sete livres de grãos, foram investigados. Doze cães Golden Retriever adultos (idade de três-quatro anos, peso corporal = 22,5 ± 1,7kg) foram divididos em três grupos. Os resultados dos ensaios de digestibilidade indicaram que os alimentos cárneos de cordeiro apresentaram as maiores digestibilidades de matéria seca, matéria orgânica e fibra bruta. Em geral, na avaliação do grupo com grãos inclusivos e do grupo sem grãos, os alimentos com grãos inclusivos mostraram maior digestibilidade das fibras brutas, enquanto os alimentos sem grãos tiveram maior digestibilidade do extrato etéreo; já as diferenças nos escores de consistência fecal entre os grupos foram insignificantes. Ao contrário da crença popular, os alimentos com inclusão de grãos eram mais digestivos do que os sem grãos, em termos de matéria seca e matéria orgânica. Existem estudos envolvendo fontes de amido em formulações de rações, mas é necessário estudar a digestibilidade de rações completas para fornecer nutrientes adequados. Além disso, cada dieta deve ser avaliada com base em seu perfil geral de nutrientes e digestibilidade, em vez de ingredientes individuais.(AU)
