ABSTRACT Peanuts are mainly grown in sandy soils with low boron content, which may limit the crop yield, especially runner-type cultivars that have high-yields. Boron deficiency causes hollow heart in peanut seeds, reducing yield and seed quality, but the best strategy to supply boron to peanut is still not known. This study aimed to evaluate peanuts nutrition, yield, and seed quality as a function of boron rate, source, and application form. The study was conducted for two years in sandy soils with low boron in southeastern Brazil. Treatments included application of boron via soil: control (boron unfertilized), boric acid at 1.5 kg ha-1 of B, Ulexite (1.5 and 3.0 kg ha-1 of B), and sodium tetraborate (1.5 and 3.0 kg ha-1 of B) combined with foliar fertilization (sub-plots): 0, 400, 800 and 1200 g ha-1 of B (boric acid) with four replicates. Boron fertilization via soil and foliar increased peanuts yield by 20 % (1100 kg ha-1) and 14 % (700 kg ha-1) - the average of the two crops, respectively. Combined use of soil and foliar fertilizer was justified only in years with water deficit and when the rate applied via soil was low (<3.0 kg ha-1). Boron application via soil or application of 400 g ha-1 of B via foliar fertilization increased seed germination rate by 10 to 13 %. Boron fertilization increased the percentage of normal seedlings, seedling weight, and length and reduced the germination time. Foliar and soil boron applications efficiently improved peanut seed nutrition, yield, and quality. However, soil application performed better, showing a higher percentage of yield increase. content runnertype runner type highyields. highyields high yields. yields high-yields seeds known nutrition source form Brazil unfertilized, unfertilized , unfertilized) 15 1 5 1. ha1 ha ha- (1. 30 3 0 3. subplots sub plots (sub-plots) 80 120 replicates 2 1100 (110 700 (70 crops respectively <3.0 (<3. ha1. . 40 seedlings weight time However better increase (1 (sub-plots 8 12 110 (11 70 (7 <3.

Abstract Despite an economy based mostly on agriculture, literature on viral diseases of plants is scarce in Paraguay. Only recently, researches on plant viruses took an impulse resulting in a precise identification of many of them affecting plants either cultivated or not. To provide reliable information regarding plant viruses present in Paraguay, an annotated list of them was prepared, covering descriptions from 1920 to present day. There have been some important outbreaks with severe yield losses in crops as cucurbits, citrus, sesame, bean, maize, peanuts and tomato. Many of older descriptions are included for their historical significance, but most identifications made require confirmation. On the other hand, recent descriptions have been completed, based on several assays, especially molecular characterization. This list is organized alphabetically following scientific names of the plant species found naturally infected by viruses, with comments about symptoms, geographical distribution, incidence, identification procedures, and other information, with due literature references. It is based on a compilation of publications made on plant virus diseases in Paraguay. Described virus species, in a total of 38 recognized by ICTV, belonging to 17 different genera (Alphaendornavirus, Ampelovirus, Begomovirus, Benyvirus, Carlavirus, Cilevirus, Closterovirus, Comovirus, Cucumovirus, Dichorhavirus, Fabavirus, Luteovirus, Ophiovirus, Orthotospovirus, Potexvirus, Potyvirus and Tobamovirus), besides two unclassified, and four unidentified. There is also a case of viroid described in Citrus spp. Infections caused by potyviruses are the most numerous. These viruses were described in more than 40 plant species, belonging to 18 botanical families. Because of crop diversity and richness in native flora, many more viruses must be present in Paraguay, which future works will certainly reveal, especially with the increase in manpower involving researches, especially cooperative with foreign centers, on plant viruses, which has been very limited until now. Also, knowledge on existing viruses may have relevance in understanding their epidemiology and provide the basis for their control strategies and quarantine measures, to avoid new variants of existing viruses or new viruses being introduced. agriculture Paraguay recently not prepared 192 day cucurbits citrus sesame bean maize tomato significance confirmation hand completed assays characterization symptoms distribution incidence procedures references 3 ICTV 1 Alphaendornavirus, Alphaendornavirus (Alphaendornavirus Ampelovirus Begomovirus Benyvirus Carlavirus Cilevirus Closterovirus Comovirus Cucumovirus Dichorhavirus Fabavirus Luteovirus Ophiovirus Orthotospovirus Potexvirus Tobamovirus, Tobamovirus , Tobamovirus) unclassified unidentified spp numerous 4 families flora reveal centers now Also measures introduced 19

Resumo A pesar de una economía basada principalmente en la agricultura, la literatura sobre enfermedades virales de las plantas es escasa en Paraguay. Sólo recientemente se han impulsado las investigaciones sobre los virus de plantas, lo que ha permitido identificar con precisión muchos de ellos que afectan a plantas cultivadas o no. Para brindar información confiable sobre los virus de plantas presentes en el Paraguay, se elaboró una lista comentada de los mismos, abarcando descripciones desde 1920 hasta la actualidad. Se han producido algunos focos importantes con severas pérdidas de rendimiento en cultivos de cucurbitáceas, cítricos, sésamo, frijol, maíz, maní y tomate. Muchas de las descripciones más antiguas se incluyen por su importancia histórica, pero la mayoría de las identificaciones realizadas requieren confirmación. Por otro lado, las descripciones recientes han sido completadas, basadas en varios ensayos, especialmente de caracterización molecular. Esta lista está organizada alfabéticamente siguiendo los nombres científicos de las especies de plantas que se encontraron naturalmente infectadas por virus, con comentarios sobre síntomas, distribución geográfica, incidencia, procedimientos de identificación y otras informaciones, con las debidas referencias bibliográficas.

ABSTRACT The success of intercropping depends on the spatial arrangement between crops, aiming at the best use of the planting area and greater profitability for the farmer. Here, we evaluated the effect of cassava-peanut intercropping on several agronomic parameters. The research was carried out in the APTA experimental area, in the state of São Paulo, Brazil. The experimental design was randomized blocks with four treatments (peanut in monoculture - P; cassava in monoculture - C, cassava intercropped with peanuts planted between rows - CPb, and intercropping in alternating double rows - CPd) and eight replications. The variables analyzed were vegetative growth of cassava plants, soil vegetation cover and weed control, incidence of the main cassava and peanut pests, productivity, and the land equivalent ratio (LER). Only CPb inhibited cassava vegetative growth, significantly affecting its final height. Greater vegetation coverage and, consequently, lower occurrence of weeds, was obtained in CPb in addition to lower incidence of whiteflies in cassava. The intercropping system, regardless of the spatial arrangement used, increased the incidence of the lace bug in cassava and reduced the incidence of peanut pests. Crop productivity was lower in CPd due to the lower planting density of intercrops. However, both intercropping arrangements increased LER. Thus, despite the spatial arrangement of the intercropping system having implied different agronomic responses of the crops, planting peanuts between the cassava rows brought the best agronomic results. crops farmer Here cassavapeanut parameters Paulo Brazil P C replications plants control pests LER .

RESUMO O sucesso de consorcio de culturas depende da boa disposição espacial entre elas, caracterizando o melhor uso da área de plantio e maior rentabilidade para o agricultor. Nesse trabalho avaliamos o efeito do consórcio entre mandioca e amendoim em diferentes aspectos agronômicos. A pesquisa foi realizada na área experimental da APTA, no estado de São Paulo, Brasil. O delineamento experimental foi de blocos ao acaso com quatro tratamentos e oito repetições. Os tratamentos foram: amendoim em monocultura (P); mandioca em monocultura (C), consórcio com o amendoim plantado na entrelinha das fileiras mandioca (CPb), e consórcio das culturas em fileiras duplas alternadas (CPd). As variáveis analisadas foram crescimento vegetativo das plantas de mandioca, cobertura do solo e controle de ervas daninhas, incidência das principais pragas da mandioca e do amendoim, produtividade das culturas consortes e o índice de uso da terra (LER). Apenas CPb inibiu o crescimento vegetativo da mandioca, afetando significativamente sua altura final. CPb obteve maior cobertura vegetal e, consequentemente, menor ocorrência de ervas daninhas, além de resultar em menor incidência de mosca-branca na mandioca. O consorcio, independente do arranjo espacial utilizado aumentou a incidência do percevejo de renda na mandioca e diminuiu a incidência das pragas do amendoim. A produtividade das culturas menor em CPd, devido a menor densidade de plantio das culturas consortes. Porém qualquer arranjo do consorcio dessas culturas aumenta a LER. Assim, apesar do arranjo espacial do consórcio ter implicado diferentes respostas agronômicas das culturas, o plantio de amendoim na entrelinha da mandioca trouxe os melhores resultados agronômicos. elas agricultor agronômicos APTA Paulo Brasil repetições P (P) C, C , (C) CPb, (CPb) CPd.

Abstract Anaphylaxis, a potentially life-threatening reaction, is characterized by acute symptoms affecting various systems and requires immediate medical intervention. While the overall mortality rate is low, anaphylaxis induced by foods and drugs has seen an increase. Common triggers include foods, drugs, and Hymenoptera venom. Epidemiology varies by region and age, with a global incidence of 50-112 episodes per 100,000 people annually. Implicated foods vary by age and region, with peanuts and nuts being common triggers. Two mechanisms of anaphylaxis are recognized: IgE-mediated and non-IgE-mediated. Diagnosis is based on clinical criteria and serum tryptase levels. Treatment includes epinephrine, oxygen, and intravenous fluids. Exercise-induced food-dependent anaphylaxis is addressed, where exercise, combined with certain foods, triggers anaphylactic reactions. Proper understanding and management are crucial to mitigate risks.

Resumen La anafilaxia, una reacción potencialmente mortal, se caracteriza por la aparición aguda de síntomas que afectan diversos sistemas y requiere intervención médica inmediata. Aunque la tasa de mortalidad general es baja, la anafilaxia inducida por alimentos y fármacos ha experimentado un aumento. Los alimentos, fármacos y veneno de himenópteros son desencadenantes comunes. La epidemiología varía según la región y la edad, con una incidencia global de 50-112 episodios anuales por cada 100,000 personas. Los alimentos más implicados varían según la edad y la región, y los desencadenantes más comunes son cacahuetes y nueces. Se reconocen dos mecanismos de anafilaxia: mediado por IgE y no mediado por IgE. El diagnóstico se basa en criterios clínicos y niveles de triptasa sérica. El tratamiento incluye epinefrina, oxígeno y líquidos intravenosos. Se aborda la anafilaxia inducida por ejercicio dependiente de alimentos, donde el ejercicio, en combinación con ciertos alimentos, desencadena reacciones anafilácticas. La comprensión y el manejo adecuados son cruciales para mitigar riesgos.

Abstract The prevalence of food allergy has increased in some regions of the world, and with it the incidence, according to geographical variability, in the phenotype and clinical manifestations. Food allergy arises from the specific immune response induced by exposure to the proteins of a certain food. Food intolerance refers to non-immune reactions, caused by unique physiological characteristics of the individual, including metabolic, toxic, pharmacological and undefined mechanisms. Adverse reactions to foods are classified as: IgE-mediated: Type I Hypersensitivity, non-IgE-mediated: Type IV Hypersensitivity, mixed: Types I and IV Hypersensitivity Non-Allergic; toxic, pharmacological, metabolic, intolerances. These types of alterations are rare but have increased in recent years; These include protein-induced enterocolitis syndrome, which can cause emesis, diarrhea and hypotension, and shock, which begins two hours after ingestion of the allergen. Protein-induced allergic proctocolitis is a condition that includes allergy to cow's milk protein. Delayed reactions usually affect the digestive system, are more insidious in their onset and are not immediately controlled, even with the suspension of food. There are eight foods responsible for 90% of food llergies: milk, eggs, soy, wheat, peanuts, walnuts, fish, and shellfish.

Resumen La prevalencia de alergia alimentaria se ha incrementado en algunas regiones del mundo, y con ello la incidencia, según la variabilidad geográfica, en el fenotipo y manifestaciones clínicas. La alergia alimentaria surge de la respuesta inmune específica inducida por la exposición a las proteínas de cierto alimento. La intolerancia alimentaria se refiere a reacciones no inmunitarias, causadas por características fisiológicas únicas del individuo, que incluyen mecanismos metabólicos, tóxicos, farmacológicos e indefinidos. Las reacciones adversas a los alimentos se clasifican en: mediada por IgE: Hipersensibilidad Tipo I, no mediada por IgE: ipersensibilidad Tipo IV, mixtas: Hipersensibilidad Tipos I y IV No Alérgicas; tóxicas, farmacológicas, metabólicas, intolerancias. Este tipo de alteraciones son poco frecuentes, pero se ha incrementado en los últimos años; entre estas se encuentra el síndrome de enterocolitis inducida por proteínas, que puede producir emesis, diarrea e hipotensión, y estado de shock, que inicia dos horas después de la ingestión del alergeno. La proctocolitis alérgica inducida por proteínas es una afectación que incluye la alergia a la proteína e leche de vaca. Las reacciones retardadas suelen afectar el aparato digestivo, son más insidiosas en su inicio y no se controlan inmediatamente, aún con la suspensión del alimento. Existen ocho alimentos responsables del 90% de alergia alimentaria: leche, huevo, soya, trigo, cacahuate, nuez, pescados y mariscos.

Abstract In recent times, the primary approach to treating food allergies involved strict avoidance of the triggering allergen. Many considered this approach as lacking true treatment, leaving patients vulnerable to even small amounts or hidden sources of the allergenic food. Desensitization or Oral Tolerance Induction (OTI) is a studied method aiming for a lasting tolerance to the allergen. The ultimate goal is permanent tolerance, where allergic reactions won't reoccur after new exposure to the triggering allergen, following a period of abstinence. The research mainly focuses on allergen-specific immunotherapy, covering three routes: oral, sublingual, and epicutaneous immunotherapy. Milk, egg, and peanuts are the extensively studied foods due to their prevalence in allergies. The oral route is favored for inducing tolerance because ingestion of a food antigen by a non-allergic individual triggers an active immune response without causing an allergic reaction. The paradigm has shifted from recommending avoidance to early consumption strategies to prevent allergies. The period from 4 to 6 months of age is considered immunologically sensitive, where children with risk factors show increased allergic sensitization risk. Implementing these recommendations, considering family and community preferences, may reduce the burden of food allergies and healthcare costs.

Resumen Hasta hace poco, el enfoque principal para tratar las alergias alimentarias implicaba evitar estrictamente el alérgeno desencadenante. Este método a menudo se consideraba insuficiente, lo que dejaba a los pacientes vulnerables a pequeñas cantidades o fuentes ocultas del alérgeno. La desensibilización, o inducción de tolerancia oral, es un método emergente que se está investigando para el tratamiento de las alergias alimentarias. El objetivo final es conseguir una tolerancia permanente, previniendo reacciones alérgicas tras una nueva exposición al alérgeno tras un periodo de abstinencia. La investigación se ha centrado en la inmunoterapia con alérgenos específicos a través de tres vías: oral, sublingual y epicutánea. La leche, el huevo y el maní son los principales alimentos estudiados debido a su prevalencia en las alergias. Se prefiere la inducción oral porque la ingestión de una persona no alérgica induce una respuesta inmune sin desencadenar una reacción alérgica. La atención de pacientes se ha desplazado de evitar el alergeno a ofrecer estrategias de consumo temprano para prevenir las alergias. En este enfoque se considera crucial el rango de edad de 4 a 6 meses. Se necesita investigación continua para evaluar los detalles de la población, los efectos a largo plazo, la viabilidad y la seguridad de estas estrategias.

Abstract Food allergy is very common throughout the world and has become a major public health problem, with 220 million people suffering from it. Food allergy has been disproportionately observed in people from industrialized or Western countries and was previously considered to predominate in the pediatric versus adult population. However, the current exponential growth of the adult population and older adults, especially in Western countries, and environmental and lifestyle changes, have profoundly changed the epidemiology of food allergy, with a growing increase even at advanced ages. The foods that represent the greatest severity and clinical impact are peanuts, walnuts, fish, shellfish, eggs, cow's milk protein, wheat, soy and seeds. Although some types of food allergies (cow's milk and egg) may disappear, peanut and tree nut allergies may persist into adulthood. The control or cure of cow's milk protein allergy is gradual throughout childhood and adolescence. Despite the predominance of allergy to fish, shellfish, peanuts, and tree nuts in most reactions in adults, the most common form of IgE-mediated food allergy is oral allergy syndrome or pollen allergy syndrome. food.

Resumen La alergia alimentaria es muy común en todo el mundo y se ha convertido en un importante problema de salud pública, pues 220 millones de personas la padecen. La alergia alimentaria se ha observado de manera desproporcionada en personas de países industrializados u occidentales, y se considera previamente con predominio en la población pediátrica versus adultos. Sin embargo, el crecimiento exponencial actual de la población adulta y adultos mayores, especialmente en los países occidentales, y los cambios ambientales y de estilo de vida, han cambiado profundamente la epidemiología de la alergia alimentaria, con un aumento creciente incluso en edades avanzadas. Los alimentos que representan mayor gravedad y repercusión clínica son: cacahuate, nuez, pescado, mariscos, huevo, proteína de leche de vaca, trigo, soya y semillas. Aunque algunos tipos de alergia alimentaria (leche de vaca y huevo) pueden desaparecer, la alergia al cacahuete y la nuez de árbol pueden persistir hasta la edad adulta. El control o curación de la alergia a la proteína de leche de vaca es gradual a lo largo de la niñez y la adolescencia. A pesar del predominio de la alergia al pescado, mariscos, cacahuates y nueces de árbol en la mayoría de las reacciones en adultos, la forma más común de alergia alimentaria mediada por IgE en es el síndrome de alergia oral o síndrome de alergia al polen-alimento.

ABSTRACT Peanut cultivation has national and global significance in agriculture and industry. Under water-limited conditions, its yield decreases to the extent that it compromises the success of the exploitation. This study focused on evaluating peanut crop yield and production components under full and deficit irrigation applied in the reproductive phase, to determine the impact of water supply on the yield of peanuts grown in the off-season in the State of São Paulo, Brazil. The experiment was conducted for two years and followed a randomized blocks design with five irrigation levels distributed in strips, with four repetitions. The treatments consisted of crop evapotranspiration replenishments from 100 to 10%. In the first year, under suitable temperatures, the maximum yield reached 3,922 kg ha-1 with the application of 277 mm of irrigation depth and decreased up to 35% with the lowest irrigation depth (48 mm). In the second year, suboptimal temperatures caused a delay in the growing cycle and caused a 33% reduction in crop yields. Despite the potential benefits of deficit irrigation in increasing water productivity, low temperatures pose a risk to peanut yield, especially during the off-season crop in the region. industry waterlimited limited conditions exploitation phase offseason off season Paulo Brazil strips repetitions 10 10% year 3922 3 922 3,92 ha1 ha 1 ha- 27 35 48 (4 mm. . mm) 33 yields productivity region 392 92 3,9 2 4 ( 39 9 3,

RESUMO O cultivo do amendoim tem importância nacional e global na agricultura e na indústria. Em condições limitadas de água, sua produtividade diminui ao ponto de comprometer o sucesso da exploração. Este estudo teve como objetivo avaliar o rendimento da cultura do amendoim e seus componentes de produção sob irrigação plena e deficitária aplicada na fase reprodutiva, para determinar o impacto do fornecimento de água no rendimento do amendoim cultivado na segunda época no Estado de São Paulo, Brasil. O experimento foi conduzido durante dois anos e seguiu um delineamento de blocos ao acaso com cinco níveis de irrigação distribuídos em faixas, com quatro repetições. Os tratamentos consistiram na reposição da evapotranspiração da cultura de 100 a 10%. No primeiro ano, sob temperaturas adequadas, o rendimento máximo atingiu 3.922 kg ha-1 com a aplicação de uma lâmina de irrigação de 277 mm e diminuiu em até 35% com a menor lâmina (48 mm). No segundo ano, temperaturas subótimas causaram atraso no ciclo de crescimento e casou redução de 33% na produtividade da cultura. Apesar dos potenciais benefícios da irrigação deficitária no aumento da produtividade da água, as baixas temperaturas representam um risco para o rendimento do amendoim na segunda safra. indústria exploração reprodutiva Paulo Brasil faixas repetições 10 10% ano adequadas 3922 3 922 3.92 ha1 ha 1 ha- 27 35 48 (4 mm. . mm) 33 safra 392 92 3.9 2 4 ( 39 9 3.

RESUMO A produção de amendoim tem crescido anualmente no Brasil. Com as secas que ocorrem frequentemente em todas as regiões brasileiras, é necessário identificar germoplasma precoce para ser utilizado em trabalhos de melhoramento visando à adaptação ambiental. Aqui, uma mini coleção de amendoim foi estudada com o objetivo de selecionar germoplasma para uso posterior em procedimentos de melhoramento, com foco em ambiente com restrição hídrica. Doze características agronômicas foram adotadas e posteriormente utilizadas em métodos multivariados, baseados em modelos hierárquicos (UPGMA) e dispersão gráfica (variáveis canônicas), visando identificar agrupamentos de acessos precoces. Diferenças estatísticas significativas foram encontradas para a maioria das variáveis, indicando variabilidade genética nos acessos estudados. Com base nas análises multivariadas, verificou-se coerência na formação de três agrupamentos, um deles (G3: PI-268-689 e AHK-85-3) aglomerou os acessos mais promissores para produção de vagens e eficiência reprodutiva, previamente identificados na análise de variância. Portanto, ambos germoplasma são recomendados para uso em trabalhos de melhoramento voltados para o ambiente com restrição hídrica.

ABSTRACT Peanut production is growing annually in Brazil, but with frequent droughts throughout the country, it is necessary to identify an earliness germplasm for the improved environmental adaptation of peanuts. Here, a mini-core collection of peanuts was studied to select germplasms for further use in breeding, with a focus on dry environments. Twelve agronomic traits were adopted and later used in multivariate methods based on hierarchical models (UPGMA) and graphical dispersion (canonical variables), which aimed to identify earliness accession clusters. Statistically significant differences were found for most traits, indicating that there was genetic variability among accessions. Multivariate analyses subsequently revealed coherence in the formation of three clusters, one of which (G3: PI-268-689 and AHK-85-3) combined the most promising accessions for pod production and reproductive efficiency, previously identified through analysis of variance. Therefore, both germplasms are recommended here for use in future breeding studies focused on water-restricted environments.

ABSTRACT: The pequi has an almond with interesting chemical characteristics, such as considerable proportions of proteins and lipids that can be applied in several products aiming to use this agro-industrial residue. This research tookadvantage of the almond for the development of sweet paçoca with different concentrations of pequi almond, containing 0% (PA), 25% (P1), 50% (P2), 75% (P3), and 100% (P4) in place of peanuts. The paçocas were evaluated for proximate parameters and water activity, mineral content, color parameters, microbiological characteristics, and texture profile. The results for aw ranged from 0.48 to 0.52. In the proximate composition, it was observed that with the increase of the almond flour there was a difference in the ash, moisture, and protein contents. Due to the almond roasting process, the paçocas of pequi presented the darkest color. Pequi almond paçocas showed better protein value than peanut paçoca and higher levels of P and Mg. In addition, they present better elasticity, chewability, and cohesiveness.

Abstract Background Phytoremediation is a technique used in soils contaminated with residual herbicides, such as tebuthiuron. However, the herbicide presence in the soil and plant matrices are not generally quantified. Objective This study aimed to select plant species to evaluate the phytoremediation of 14C-tebuthiuron by showy rattlepod (Crotalaria spectabilis), sorghum (Sorghum bicolor), radish (Raphanus sativus), peanut (Arachis hypogaea), and alfalfa (Medicago sativa) in herbicide-contaminated soil. Methods The selection of the five herbicide phytoremediation plants was with the application of five rates of tebuthiuron (300, 600, 1,200, 2,400, and 4,800 g a.i. ha-1) and compared to a control. Peanuts and sorghum (herbicide-tolerant plants) were sown in soil contaminated with tebuthiuron (600 g a.i. ha-1) applied through a working solution containing 17.47 kBq of 14C-tebuthiuron. The total of herbicide was analyzed in the soil and plant at three phenological stages. Results Showy rattlepod, radish, and alfalfa were sensitive to the herbicide even at the lowest application rate. Sorghum was tolerant to the herbicide up to 600 g ha-1 with the application of 1,200 g ha-1, there was 80% injury; peanut was tolerant even at the highest rate (4,800 g ha-1) with only 40% injury. Peanut and sorghum were able to phytoremediate the soil, although, peanut was more efficient in decreasing tebuthiuron contamination by 76%, while sorghum reduced at by 45% at 3rd phenological stage. Conclusions Thus, both plants can be recommended in succession/rotation with crops that had tebuthiuron applied from pre-emergence weed control. herbicides However quantified 14Ctebuthiuron Ctebuthiuron 14C C Crotalaria spectabilis, spectabilis , spectabilis) bicolor, bicolor bicolor) Raphanus sativus, sativus sativus) Arachis hypogaea, hypogaea hypogaea) Medicago sativa herbicidecontaminated 300, 300 (300 1200 1 200 2400 2 400 2,400 4800 4 800 4,80 ai i a.i ha1 ha control herbicidetolerant (60 1747 17 47 17.4 14Ctebuthiuron. stages 60 ha- 1,20 ha1, 1, 80 injury (4,80 40 although 76 76% 45 rd stage Thus successionrotation succession rotation preemergence pre emergence 30 (30 120 20 240 2,40 480 4,8 (6 174 17. 6 1,2 8 (4,8 7 3 (3 12 24 2,4 48 4, ( (4, 2, (4

ABSTRACT: Salmonella is a relevant pathogen, which causes foodborne outbreaks associated with both high and low moisture foods (LMF). This study evaluated the effect of previous desiccation stress on the acid resistance of S. Typhimurium ATCC 14028 using blanched peanut kernels as an LMF model. Salmonella was recovered from the peanut samples throughout 180 days of blanched peanut kernels storage at 28 ºC. During this period two death rates were verified, 0.04 log cfu/g/day in the first 30 days and 0.007 log cfu/g/day between 30 and180 days.Regarding acid resistance, there was no difference (P > 0.05) in the Salmonella growth/death kinetics between the undesiccated sample (TSB)and the cells recovered from peanut samples over 180 days of storage after 4 h at pHs 3.0, 3.5, 4.5 and 7.2. The average growth rate observed for pH 7.2 was 0.44 log cfu/ml/h. At pH 4.5, the Salmonella counts did not change significantly over 4 h. In contrast, Salmonella populations declined by 0.14 to 0.29 log cfu/ml/h at pH 3.5. At pH 3.0 declines were estimated to be 0.65 log cfu/ml/h for the undesiccated sample and 2.07 log cfu/ml/h for Salmonella recovered from peanuts stored for 120 days.

RESUMO: Em alimentos de baixa umidade (LMF), o primeiro desafio encontrado por patógenos como a Salmonella é o estresse de dessecação. Neste estudo, o efeito prévio do estresse de dessecação sobre a resistência ácida de S. Typhimurium ATCC 14028 foi avaliado utilizando amendoim blancheado como um modelo de LMF. Salmonella foi recuperada das amostras de amendoim após 180 dias de estocagem a 28 ºC. Durante este período foram verificadas duas taxas de mortalidade, 0,04 log ufc/g/dia nos primeiros 30 dias e 0,007 log ufc/g/dia entre 30 e 180 dias. Com relação à resistência ácida, não houve diferença (P > 0,05) na cinética de crescimento/morte de Salmonella entre a amostra sem estresse dessecativo (TSB) e as amostras de amendoim após 4 h em pHs 3,0, 3,5, 4,5 e 7,2. A taxa média de crescimento observada para o pH 7,2 foi de 0,44 log cfu/ml/h. No pH 4,5, a contagem de Salmonella não mudou significativamente durante 4 h. Em contraste, a população de Salmonella diminuiu de 0,14 a 0,29 log cfu/ml/h no pH 3,5. No pH 3,0, a queda foi estimada em 0,65 log cfu/ml/h para a amostra sem estresse dessecativo e 2,07 log cfu/ml/h para a Salmonella recuperada das amostras de amendoim estocadas por 120 dias. Portanto, nossos dados indicaram que o estresse dessecativo causado durante a estocagem do amendoim não influenciou a resistência ácida de Salmonella.

Abstract Objective The prevalence of food allergies (FA) has increased worldwide over the last few decades. Milk, eggs, and peanuts are among the most common allergens and can cause anaphylaxis. Therefore, we aimed to identify biomarkers that could predict the persistence and/or severity of IgE-mediated allergies to milk, eggs, and peanuts via a systematic review. Methods This systematic review proceeded according to a protocol registered in the International Prospective Register of Systematic Reviews. Two independent authors extracted studies of interest from PubMed, SciELO, EMBASE, Scopus, and Ebsco databases and assessed their quality using the Newcastle-Ottawa Scale. Results We selected 14 articles describing 1,398 patients. Among eight identified biomarkers, total IgE, specific IgE (sIgE), and IgG4 were the most often cited biomarkers of persistent allergies to milk, eggs, and peanuts. Skin prick tests, endpoint tests, and sIgE cutoff levels may predict positive responses to challenges with these foods. The basophil activation test is a biomarker for the severity and/or threshold of allergic reactions to milk and peanuts. Conclusion Only a few publications identified possible prognostic indicators of the persistence or severity of FA and outcomes of oral food challenges, indicating that more accessible biomarkers are needed to determine the likelihood of having a severe food allergic reaction.

ABSTRACT Two-stage harvesting is the main method for performing the mechanized harvesting of peanuts, and the picking device is a core part of the combined harvester in China. In order to solve the problem of pod loss caused by the "stacking", "impact" and "throwing up" of peanut plants by a traditional cam-slide spring-finger cylinder picking device, the shovel-finger and cylinder peanut-picking device was developed and used in a picking-up performance test based on the study of peanut-plant strip-picking characteristics. The mathematical model of the mechanism was established by analyzing the structure of the mechanism and the peanut-plant strip-picking characteristics, and the parameters of the mechanism were optimized using the objective function method. The prototype was developed and tested. The experiments in which the prototype was used to collect peanut plants indicated that the phenomenon of peanut plants being stacked and thrown disappeared. Through a response surface analysis and prototype test, the optimal working parameters of the picking device were obtained: the forward speed V was 48.0 m/minute, the rotational speed N was 45.3 r/minute and the ground height H was -18 mm. The peanut-plant picking rate was 98.9% and the fruit loss rate was 2.8% under two different harvesting conditions for which the peanut-plant moisture content was 15~17%.

Abstract Several studies have been carried out to expand the use of Ricinus communis L. castor bean (Ricinus communis L castor bean.). This oilseed finds appropriate conditions for its development in Brazil, with more than 700 applications. The main allergens of this plant are Ric c1 and Ric c3, that cross-react with various aeroallergens and food allergens such as peanuts, soybeans, corn, and wheat. This study aimed to determine the effect of mutations in Ric c3 amino acid residues known to affect IgE binding and allergy challenges. Based on the Ric c3 structure, B-cell epitopes, and amino acid involved in IgE binding, we produce recombinant mutant protein, mrRic c3, secreted from E. coli. Strategic glutamic acid residues in IgE-biding regions were changed by Leucine. The allergenicity of mrRic c3 was evaluated by determination of IgE, IgG1, and total IgG in immunized Balb/c mice and by degranulation assays of mast cells isolated from Wistar rats. The mrRic c3 presented a percentage of mast cell degranulation close to that seen in the negative control, and the immunization of mice with mrRic c3 presented lower levels of IgE and IgG1 than the group treated with the protein without mutations. The mutant mrRic c3 had an altered structure and reduced ability to stimulate pro-inflammatory responses and bind IgE but retained its ability to induce blocking antibodies. Thus, producing a hypoallergenic mutant allergen (mrRic c3) may be essential in developing new AIT strategies. bean.. bean. . bean.)

Resumo Vários estudos têm sido realizados para ampliar o uso da mamona Ricinus communis L. (Ricinus communis L), oleaginosa que encontra condições adequadas para seu desenvolvimento no Brasil com mais de 700 aplicações. Os principais alérgenos desta planta são Ric c1 e Ric c3 que apresentam reação cruzada com vários alérgenos dispersos no ar e alérgenos alimentares, como amendoim, soja, milho e trigo. Este estudo teve como objetivo determinar o efeito de mutações nos resíduos de aminoácidos, presentes, em epítopos ligantes de IgE, de Ric c3 envolvidos no desencadeamento de respostas alérgicas. Com base na estrutura de Ric c3, epítopos de células B, e aminoácidos envolvidos na ligação de IgE, produzimos, em E. coli. uma proteína mutante recombinante, denominada mrRic c3. Resíduos estratégicos de ácido glutâmico, presentes nestes epítopos, foram alterados por Leucina. A alergenicidade da proteína mrRic c3 foi avaliada pela determinação dos níveis séricos de IgE, IgG1 e IgG total em camundongos Balb/c imunizados com a proteína mutante e por ensaios de degranulação de mastócitos isolados de ratos Wistar. A proteína mrRic c3 promoveu um percentual de degranulação de mastócitos próximo ao observado no controle negativo e camundongos imunizados com mrRic c3 apresentou níveis de IgE e IgG1 menores que o grupo tratado com a proteína recombinante nativa. A mutante mrRic c3 apresentou estrutura alterada e capacidade reduzida de estimular respostas pró-inflamatórias e de se ligar a IgE, mas manteve sua capacidade de induzir anticorpos bloqueadores. Assim, a produção de um alérgeno mutante hipoalergênico (mrRic c3) pode ser uma etapa essencial no desenvolvimento de novas estratégias para a AIT.
