ABSTRACT The use of cold plasma is effective in overcoming seed dormancy. However, its effects, both in the long-term and during storage, is still not fully understood. The aim of this study, therefore, was to evaluate the immediate and post-storage effect of atmospheric plasma on the seeds of Pityrocarpa moniliformis in overcoming seed coat dormancy. The seeds were treated with plasma for 0, 1.0, 2.0, 3.0, 4.0 and 5.0 minutes. Following application, 50% of the seeds were stored for two years while the remainder were submitted to immediate analysis. The seeds were evaluated for germination and the germination speed index, in addition to seedling length and dry weight. The experimental design was completely randomised, and included regression analysis. The plasma treatment resulted in an increase in the germination rate and vigour of the seeds, both immediately after exposure and after two years of storage. In particular, the seeds treated for five minutes showed around 39% germination, which was outstanding compared to seeds from other exposure times. Plasma is effective in overcoming seed coat dormancy in seeds of P. moniliformis treated for five minutes and tested immediately. The effect of plasma on the seeds of P. moniliformis after storage was less for all the conditions under test.

ABSTRACT Cobalt (Co) and molybdenum (Mo) are essential elements with a fundamental role in biological nitrogen fixation in legumes. Vitamins such as thiamine, despite being required in small quantities, influence plant growth. This study aimed to assess the efficiency of different doses of thiamine applied as seed treatment, combined or not with Co and Mo, in enhancing the development of soybean crops. The experiment was conducted in a greenhouse according to a randomized block design with a 6 × 2 factorial arrangement, comprising six thiamine doses (0, 10, 25, 50, 100, and 200 mg kg-1) in the presence or absence of Co and Mo at the recommended rate of 100 mL ha-1. At 40 days after sowing, plants were analyzed for root length, root dry weight, shoot length, shoot dry weight, nodule number, and nodule dry weight. Principal component analysis showed that combined application of Co and Mo with thiamine was negatively associated with all variables and that the thiamine doses most positively associated with the analyzed variables were 50 and 200 mg kg-1. In treatments containing thiamine alone, there was a linear direct relationship between thiamine dose and nodule dry weight. Root and shoot lengths and dry weights were highest in plants treated with thiamine only at a dose of 122 mg kg-1. Application of Co and Mo combined with thiamine via seed treatment does not promote the development of soybean crops. Thiamine application is a promising treatment to increase shoot length, root dry weight, and nodule dry weight in soybean.

ABSTRACT This study investigated the effectiveness of using the X-ray technique to assess the viability of papaya seeds. The X-ray images were performed in eight replicates of 25 seeds, placed on transparent acrylic plates on double-sided adhesive tape, previously identified, and then submitted to radiation in X-ray equipment "HP Faxitron". After exposure to X-ray radiation, the seeds were submitted to the germination test in rolls of germitest paper and kept in a germination chamber at 20-30 °C for 30 days. Seedlings were photographed and evaluated as normal seedlings, abnormal and non-germinated seeds. Afterward, the X-ray images and the seedlings from the same seeds were visually compared, and the X-ray images clearly showed seeds with and without internal filling. All abnormal seedlings were full seeds; therefore, X-ray images were not able to separate normal and abnormal. A 100% accuracy was verified by comparing the X-ray images and their respective seedlings, full seeds originated normal or abnormal seedlings, and empty seeds corresponded to non-germinated seeds. Therefore, using X-ray images is a promising technique to identify the viability of papaya seeds. The automated analysis of X-ray images is a simple, fast, and efficient technique to provide information on seed viability and generate parameters related to their germination capacity.

Abstract The aim of this study was to evaluate the effects of different pharmaceutical forms of Butaphosphan on milk production and the metabolism in dairy cows during the postpartum period. After in vitro and pharmacokinetic assays, thirty-six multiparous cows belonging to the Holstein breed, were randomly divided into three groups: Group BUT (n=12), that received an aqueous solution of Butaphosphan (150 mg/mL); Group BUTSR (n=12), that received a sustained-release formulation of Butaphosphan (150 mg/mL) and Group Control (CL ; n=12), that received saline solution (NaCl 0.9 %). All the groups received three subcutaneous doses of 30 mL in the neck region, on the day of parturition (day 0) and 3 and 7 days after parturition. Blood samples were collected on days 0, 3, 7 and 10, postpartum. Daily milk production was evaluated from day 11 to 60, postpartum. The animals of the BUTSR group presented greater (P=0.01) milk production than the other groups. It was observed that the BUTSR and BUT groups showed higher blood levels of calcium (P=0.01) than the animals in the CL group. The BUTSR group obtained higher milk production compared to other groups, demonstrating that this pharmaceutical form has great potential for a future product and could be an alternative for the market. More studies are needed to better understand the action of Butaphosphan on the metabolism of dairy cows in the recent postpartum period. period assays thirtysix thirty six breed n=12, n12 n n=12 , 12 (n=12) 150 (15 mg/mL mgmL mg sustainedrelease sustained release n=12) NaCl 09 0 9 0. %. % . %) region 10 1 60 P=0.01 P001 P 01 (P=0.01 market n1 n=1 (n=12 15 (1 6 P=0.0 P00 (P=0.0 n= (n=1 ( P=0.

Resumo O objetivo deste estudo foi avaliar os efeitos das diferentes formas farmacêuticas contendo Butafosfan sob a produção de leite e o metabolismo de vacas leiteiras durante o pós-parto. A partir de ensaios in vitro e in vivo, duas formas farmacêuticas foram testadas em animais de produção. Trinta e seis vacas da raça Holandês, foram divididas aleatoriamente em três grupos: Grupo BUT (n=12), que recebeu solução aquosa de Butafosfan (150 mg mL-1); BUTSR (n=12), que recebeu uma formulação de liberação prolongada de Butafosfan (150 mg mL-1) e o Grupo CL (Controle; n=12), que recebeu solução fisiológica de cloreto de sódio. Todos os grupos, tiveram administração de três doses subcutâneas de 30 mL. A aplicação foi realizada no dia do parto (dia 0) e nos dias 3 e 7 após o parto. Amostras de sangue foram coletadas nos dias 0, 3, 7 e 10 para avaliação de parâmetros metabólitos e a produção de leite foi avaliada do dia 11 aos 60 dias pós-parto. O grupo BUTSR apresentou maior produção de leite (P=0.01), em comparação aos demais grupos. Observou-se que os grupos BUTSR e BUT apresentaram maiores níveis sanguíneos de cálcio (P=0.01) que os animais do grupo CL. O grupo BUTSR obteve maior produção de leite em comparação aos demais grupos, demonstrando que essa forma farmacêutica possui grande potencial, podendo ser uma alternativa para o mercado.

ABSTRACT Banana is a climacteric fruit with short post-harvest shelf-life, undergoing significant changes during ripening. Refrigerated storage is considered the most efficient method to preserve the quality of fruit by slowing down their metabolism. Thus, the objective of this work was to evaluate physical and chemical characteristics of 'BRS-Princesa' bananas stored under refrigeration, focusing on determining their post-harvest shelf-life. The fruit were stored in a cold chamber at temperature of 14±1 °C and relative air humidity of 75±1% for 0, 7, 14, 21, and 28 days. They were removed from the cold chamber after each period and kept at 25±1 °C in a climate-controlled environment (CCE) until they presented a fully yellow peel (ripening stage 6). The fruit were evaluated immediately after removal from the cold chamber and when they reached the ripening stage 6. Refrigeration affected all physical and chemical characteristics of the fruit evaluated after removal from the cold chamber. However, when the fruit were fully ripe, pulp yield, soluble solids content, and total soluble sugars presented no significant difference, indicating a similar ripening to the control group. Fruit stored for 21 and 28 days showed chilling injury. 'BRS-Princesa' bananas can be stored at 14 °C for up to 14 days, without losses in fruit appearance and quality, thus extending the time for fruit consumption by 8 days when compared to fruit stored in the CCE (25±1 °C). postharvest post harvest shelflife, shelflife shelf life, life shelf-life metabolism Thus BRSPrincesa BRS Princesa 'BRS-Princesa refrigeration shelflife. life. 141 1 14± C 751 75 75±1 0 7 2 251 25 25± climatecontrolled climate controlled (CCE 6 . 6) However ripe yield content difference group injury (25± °C. °C) 75± (25 (2 (

RESUMO A banana é um fruto climatérico de vida pós-colheita curta e que sofre mudanças acentuadas durante seu amadurecimento. O armazenamento refrigerado é considerado a forma mais eficaz de preservar a qualidade dos frutos, diminuindo seu metabolismo. Assim, o trabalho teve como objetivo avaliar as características físicoquímicas de bananas 'BRS-Princesa' armazenadas sob refrigeração, visando determinar o período de vida útil pós-colheita. Os frutos foram armazenados em câmara fria, em temperatura de 14±1 ºC e 75±1% UR por períodos de 0, 7,14, 21 ou 28 dias. Após cada período, os frutos foram retirados da câmara fria e mantidos em temperatura ambiente (25±1 ºC) até apresentarem coloração da casca completamente amarela (estádio 6 de maturação). As avaliações foram realizadas logo após a retirada dos frutos da refrigeração e quando os frutos atingiram o estádio 6. A refrigeração afetou todas as variáveis de qualidade físico-química dos frutos avaliados após a retirada da câmara fria. Porém, quando os frutos atingiram o completo amadurecimento, as variáveis rendimento da polpa, sólidos solúveis e açúcares solúveis totais não apresentaram diferença significativa, indicando um amadurecimento semelhante ao controle. Frutos armazenados por 21 e 28 dias apresentaram índices de injúrias por frio. As bananas 'BRS-Princesa' podem ser armazenadas a 14 °C por um período de até 14 dias, sem prejuízo à boa aparência e qualidade dos frutos, com incremento de 8 dias na possibilidade de consumo dos frutos, quando comparados ao controle. póscolheita pós colheita metabolismo Assim BRSPrincesa BRS Princesa 'BRS-Princesa póscolheita. colheita. 141 1 14± 751 75 75±1 0 714 7 7,14 2 25±1 251 25 (25± maturação. maturação . maturação) físicoquímica físico química Porém polpa significativa controle frio C 75± 71 7,1 25± (25 7, (2 (

Abstract Objective: To evaluate the application of the Antimicrobial (ATM) treatment time reduction strategy in Intensive Care Units (ICU) in an Antimicrobial Stewardship Program (ASP). Method: This is a descriptive and cross-sectional study, carried out in two ICU of a university hospital in Fortaleza, Brazil, from January/2017 to January/2019. Adult patients were included, accompanied by a pharmacist, and using ATM, in which the treatment time reduction strategy was applied. The evaluation of the strategy was made through the difference between the predicted time established at the beginning of the treatment and the effective days of use of each ATM. Results: Of the 100 patients included, 51.0 % were male and 64.0 % were elderly. The respiratory system was the most frequently affected by the infections (37.4 %) and the most prevalent classes of ATM were carbapenems (23.0 %) and glycopeptides (20.1 %). There was a decrease from 831 unnecessary days of antimicrobial therapy and from an average of 13.7 to 8.9 days of treatment. The greatest reductions in days were observed for meropenem, with 202 days reduced. The study also allowed the identification of associations between the reduction > 8 days of treatment and the variables length of stay > 22 days and patients in exclusive palliative care, and associations between hospital discharge and reductions of up to 7 days of therapy. Conclusions: The data obtained suggest that the presence of an ASP influences the practices of ATM use and its treatment time and emphasize the role of pharmaceutical professionals in these programs.

Resumen Objetivo: Evaluar la aplicación de la estrategia reducción del tiempo de tratamiento Antimicrobiano (ATM) en Unidades de Cuidados Intensivos (UCI) en un Programa Stewardship de Antimicrobiano (ASP). Método: Este es un estudio descriptivo y transversal, realizado en dos UCI de un hospital universitario de Fortaleza, Brasil, de enero/2017 a enero/2019. Se incluyeron pacientes adultos, acompañados por un farmacéutico y utilizando ATM, en los que se aplicó la estrategia de reducción del tiempo de tratamiento. La evaluación de la estrategia se realizó a través de la diferencia entre el tiempo previsto establecido al inicio del tratamiento y los días efectivos de uso de cada ATM. Resultados: De los 100 pacientes incluidos, 51,0 % eran del sexo masculino y 64,0 % ancianos. El sistema respiratorio fue el más frecuentemente afectado (37,4 %) y las clases de ATM más prevalentes fueron los carbapenémicos (23,0 %) y los glicopéptidos (20,1 %). Hubo una disminución de 831 días innecesarios de terapia antimicrobiana y de un promedio de 13,7 a 8,9 días de tratamiento. Las mayores reducciones en días se observaron para meropenem, con 202 días reducidos. El estudio también permitió identificar asociaciones entre la reducción > 8 días de tratamiento y las variables estancia > 22 días y pacientes en cuidados paliativos exclusivos; y asociaciones entre alta hospitalaria y reducciones de hasta 7 días de terapia. Conclusiones: Los datos obtenidos sugieren que la presencia de un ASP influye en las prácticas de uso de ATM y su tiempo de tratamiento y enfatizan el papel de los profesionales farmacéuticos en estos programas.

RESUMO: O objetivo deste estudo foi avaliar o efeito da suplementação proteica materna sobre o metabolismo energético do músculo esquelético de bezerros de corte. Dezesseis matrizes gestantes foram divididas em três grupos: CONTROLE (não suplementado); MÉDIO (suplementados entre 30 e 180 dias de gestação); e FINAL (suplementado entre 181 e 281 dias de gestação). O suplemento continha 30% de proteína bruta e foi fornecido em quantidades totais iguais aos tratamentos. Trinta dias após o nascimento, amostras de sangue e músculo dos bezerros foram coletadas para análises de expressão gênica, abundância de proteínas e metabólitos. Não foram observadas diferenças (P ≥ 0,15) no peso ao nascimento ou parâmetros de desempenho ao desmame, bem como na expressão dos genes avaliados (P ≥ 0,21). Os bezerros nascidos de matrizes do tratamento CONTROLE apresentaram menor proporção (P = 0,03) de proteína p-AMPK/AMPK no músculo esquelético. Os bezerros nascidos de matrizes do tratamento MÉDIO apresentaram concentração de glicose menor (P = 0,04) do que aqueles nascidos de matrizes do tratamento FINAL. Os resultados observados indicam que a ausência de suplementação proteica em matrizes gestantes pode alterar o metabolismo energético da progênie e refletir em uma inflexibilidade metabólica, a qual pode ocasionar limitações quanto à eficiência energética do tecido muscular esquelético e consequentemente, limitar o desempenho da progênie ao longo da fase pós-natal.

ABSTRACT: This study evaluated the effect of maternal protein supplementation during mid or late gestation on energy metabolism of the skeletal muscle of beef calves. Sixteen pregnant cows were divided into 3 groups: CTRL (not supplemented); MID (supplemented from 30 to 180 days of gestation); and LATE (supplemented from 181 to 281 days of gestation). The supplement contained 30% crude protein. Thirty days after birth, blood and muscle samples of the calves were collected for analyses of gene expression, proteins, and metabolites. No differences (P ≥ 0.15) in birth weight, performance at weaning, or muscle expression of the genes evaluated (P ≥ 0.21) were observed. Calves born to CTRL cows had a lower ratio (P = 0.03) of p-AMPK/AMPK protein in the skeletal muscle. Calves born to MID cows had lower (P = 0.04) glucose concentration than those born to LATE cows. Changes in p-AMPK/AMPK protein, indicated a possible metabolic inflexibility in the skeletal muscle of calves born to CTRL cows. These results indicated that lack of protein supplementation in pregnant cows alter the energy metabolism of their calves and reflect in a metabolic inflexibility.

RESUMO Estabelecer os procedimentos adequados para condução do teste de germinação em espécies florestais é importante para viabilizar a comercialização de lotes de sementes, sobretudo para espécies que ainda não constam nas Instruções Normativas. Objetivou-se com este estudo determinar as condições ideais de temperatura e substrato para a realização do teste de germinação de sementes de Senna siamea, bem como: (i) caracterizar a morfo-fisiologia do estabelecimento da plântula, (ii) o período para a avaliação das plântulas, e (iii) validar a eficiência da metodologia em 10 lotes de sementes. O delineamento utilizado foi inteiramente ao acaso em arranjo fatorial 2 x 2 (temperaturas x substratos) com 12 repetições de 50 sementes para cada tratamento. Para a avaliação dos diferentes lotes, os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Scott-Knott ao nível de 5% de probabilidade. Avaliou-se o percentual e a velocidade de germinação, primeira contagem, comprimento de plântulas, germinação acumulada, e morfologia de plântulas. Sementes de S. siamea possuem maior potencial germinativo em substrato rolo de papel sob temperaturas de 25 e 30 °C (86% e 87%). A primeira contagem de germinação e avaliação final de plântulas deve ser feita aos 15 e 21 dias após a semeadura, respectivamente. A espécie possui germinação do tipo epígea e suas plântulas são fanerocotiledonares. Observou-se que as condições de execução e avaliação do teste de germinação recomendadas neste estudo são adequadas na avaliação de lotes de sementes de S. siamea.

ABSTRACT Establishing the appropriate procedures for conducting germination tests in forest species is important for marketing the seeds, especially species that are not yet included in the relevant Normative Instructions. The aim of this study was to determine the ideal conditions of temperature and substrate to carry out the germination test on seeds of Senna siamea, as well as: (i) to characterise the morpho-physiology of seedling establishment, (ii) the period for seedling evaluation, and (iii) validate the efficiency of the methodology in 10 batches of seeds. The experimental design was completely randomised in a 2 x 2 factorial scheme (temperatures x substrates), with 12 replications of 50 seeds in each treatment. To evaluate the different batches, the data were submitted to analysis of variance, and the mean values compared by the Scott-Knott test at 5% probability. The percentage and speed of germination, first count, seedling length, accumulated germination, and seedling morphology were evaluated. The germination potential of S. siamea seeds is greater on paper-roll substrate at temperatures of 25 °C and 30 °C (86% and 87%). The first germination count and final seedling evaluation should be carried out 15 and 21 days after sowing, respectively. The species has epigeal germination and the seedlings are phanerocotyledonous. It was found that the method for carrying out and evaluating the germination test recommended in this study is suitable for evaluating batches of S. siamea seeds.

ABSTRACT Among the main problems that compromise the development of forest species are water and salt stresses, especially in the early stages of development, when seedlings are more sensitive. Thus, the objective of this study was to evaluate the morphophysiological and biochemical changes in Enterolobium contortisiliquum seedlings subjected to abiotic stresses. The experimental design was randomized complete blocks (RCB), composed of five treatments, with four replicates, and the experimental plot consisted of twenty plants. From the 31st day after sowing, when the seedlings reached approximately 15 cm in height, they began to receive the treatments, which consisted of different levels of electrical conductivity of irrigation water (0.3; 2; 4; 6; 8 dS m-1) for salt stress and periods of water restriction (0; 4; 8; 12 and 16 days without irrigation) for water stress. The traits evaluated were: plant height, root length, stem diameter, number of leaves, leaf area, total dry matter, Dickson quality index, height/shoot dry matter ratio, total soluble sugars, starch, total amino acids and proline. An increase in the electrical conductivity of irrigation water and days without irrigation compromised the development of E. contortisiliquum seedlings, which was intensified from 2 dS m-1 and four days without irrigation for salt and water stresses, respectively. The mechanism of survival of E. contortisiliquum to abiotic stresses involves reduction in the growth and quality of seedlings, with activation of biochemical defense mechanisms of the species. sensitive Thus RCB, RCB , (RCB) treatments replicates plants st sowing 1 height 0.3 03 0 3 (0.3 4 6 m1 m (0 were length diameter leaves area index heightshoot shoot ratio sugars starch proline E m- respectively (RCB 0.

RESUMO Quando produzidas mudas de Ilex paraguariensis através da propagação vegetativa, a seleção correta das populações, genótipos, e ser capaz de obter material juvenil, são fundamentais para seu sucesso. Assim, o objetivo desta pesquisa foi testar sua propagação vegetativa por estaquia e resgate utilizando galhos destacados de diferentes populações do estado de Santa Catarina, Brasil. Desta forma, dois experimentos foram instalados em setembro de 2019 para testar: I) a estaquia de quatro populações, pertencentes aos municípios de Catanduvas (CT), Painel (PL), Três Barras (TB) e Urupema (UR), utilizando dez genótipos escolhidos aleatoriamente de cada, e; II) a brotação epicórmica de galhos destacados destas mesmas populações. Ambos os experimentos foram conduzidos em Lages, Santa Catarina. Em fevereiro de 2020, a estaquia foi avaliada de acordo com as porcentagens de: sobrevivência, calos, enraizamento, novas brotações e permanência das folhas originais. Os galhos foram avaliados a cada 30 dias após seu acondicionamento observando as porcentagens de galhos com brotações, número de brotações e comprimento em centímetros. Para a estaquia, houve baixa sobrevivência em todas as populações (<15%), mas com maior vigor em alguns genótipos, tais como TB1 (46%), TB7 e TB3 (ambos 28%). A maior parte das estacas vivas apresentou calo, característico de material de elevada maturidade. O enraizamento foi baixo nos níveis de população (<1,5%) e genótipo (<10%). Os galhos apresentaram brotações até 60 dias, com TB apresentando o maior número total de brotações (aproximadamente 300) e de maior comprimento médio (2,8 cm). Em termos gerais, a sobrevivência e o enraizamento de estacas foram afetados por ambos população e genótipo, destacando-se TB. Uma resposta similar foi observada para a brotação de galhos.

ABSTRACT When producing Ilex paraguariensis seedlings through vegetative propagation, selecting the correct populations and genotypes, and obtaining juvenile material, may be fundamental for its success. Therefore, this search aimed to test its vegetative propagation through cutting and rescue using detached branches of different populations in Santa Catarina state, Brazil. Thus, two experiments were installed in September 2019 in order to test: I) the cuttings of four populations belonging to the municipalities of Catanduvas (CT), Painel (PL), Três Barras (TB), and Urupema (UR), using ten randomly chosen genotypes from each, and; II) the epicormic sprouting of detached branches from these same populations. Both experiments were carried out in Lages, Santa Catarina. In February 2020, the cutting was evaluated according to the percentages of survival, callus, rooting, new sprouts, and original leaves permanence. The branches were evaluated every 30 days after storing, observing the percentages of sprouting branches, number of sprouts, and length of sprouts in centimeters. As for cutting, there was a low survival percentage in all populations (<15%), but some genotypes presented greater vigor, such as TB1 (46%), TB7, and TB3 (both 28%). Most live cuttings presented calluses (>70%), characteristic of material of high maturity. Rooting was low for populations (<1.5%) and genotypes (<10%). Branches presented sprouts up to 60 days, with TB presenting the highest total number of sprouts (approximately 300) and the greatest average length (2.8 cm). In general, survival and rooting of cuttings were affected by both populations and genotypes, highlighting TB. A similar response was observed for the branches’ sprouting. New studies with more populations, further analyses of the branches’ characteristics, and better storage conditions are recommended. success Therefore state Brazil Thus 201 I CT, CT , (CT) PL, PL (PL) TB, (TB) UR, UR (UR) each II Lages 2020 callus permanence 3 storing centimeters <15%, 15 <15% (<15%) vigor 46%, 46 46% (46%) TB7 28%. 28 28% . 28%) >70%, 70 >70% (>70%) maturity <1.5% 1 5 (<1.5% <10%. 10 <10% (<10%) 6 approximately 300 2.8 2 8 (2. cm. cm cm) general characteristics recommended 20 (CT (PL (TB (UR 202 <15 (<15% 4 (46% 7 >70 (>70% <1.5 (<1.5 <10 (<10% 2.

ABSTRACT The fungi presence during seed maturation and dispersion is related to biotic and abiotic factors. These microorganisms can cause loss seeds physiological quality in unfavorable climatic conditions. We hypothesize that sanitary quality of seeds produced is affected by tree and origin climatic condition. The aim was evaluated fungi incidence and seeds quality of Pityrocarpa moniliformis from different trees and two climatic conditions (Aw: rainy tropical; and BSh: warm semiarid). We collected seeds from 28 parent trees, evaluating separately the physiological and sanitary quality of the seeds produced in each tree. Different trees originated seeds with differences in physiological quality and fungi incidence. The climatic condition of the trees' origin affected the amount and fungi species present in the seeds produced, with a predominant incidence of the genera Alternaria spp., Aspergillus spp., Botrytis spp., Fusarium spp., Penicillium spp. and Rhyzopus sp. The Alternaria spp. incidence is correlated with seeds of low physiological quality. Therefore, we conclude that Pityrocarpa moniliformis trees under a tropical rainy climate produce seeds with superior physiological and sanitary quality compared to those located in a warm semiarid climate.

RESUMO A presença de fungos potencialmente prejudiciais durante a maturação e dispersão das sementes tem relação com fatores bióticos e abióticos. Esses microrganismos podem causar perda da qualidade fisiológica de sementes em condições climáticas desfavoráveis. Nesta pesquisa, levantou-se a hipótese de que a qualidade sanitária das sementes produzidas é afetada pela árvore e condição climática de origem. Assim, objetivou-se avaliar a incidência de fungos e a qualidade de sementes de Pityrocarpa moniliformis provenientes de diferentes árvores e duas condições climáticas (Aw: tropical chuvoso; e BSh: semiárido quente). Coletaram-se sementes de 28 árvores, avaliando-se separadamente a qualidade fisiológica e sanitária das sementes produzidas em cada árvore. Diferentes árvores originaram sementes com diferenças na qualidade fisiológica e incidência de fungos. A condição climática de origem das árvores afetou a quantidade e a espécie fúngica presente nas sementes produzidas, com incidência predominante dos gêneros Alternaria spp., Aspergillus spp., Botrytis spp., Fusarium spp., Penicillium spp. e Rhyzopus sp, sendo a incidência de Alternaria spp. correlacionada com sementes de baixa qualidade fisiológica. Portanto, conclui-se que árvores de Pityrocarpa moniliformis sob clima tropical chuvoso produzem sementes de qualidade fisiológica e sanitária superior em relação àquelas localizadas em clima semiárido quente.

ABSTRACT BACKGROUND: Morbidity of liver resections is related to intraoperative bleeding and postoperative biliary fistulas. The Endo-GIA stapler (EG) in liver resections is well established, but its cost is high, limiting its use. The linear cutting stapler (LCS) is a lower cost device. AIMS: To report open liver resections, using LCS for transection of the liver parenchyma and en bloc stapling of vessels and bile ducts. METHODS: Ten patients were included in the study. Four patients with severe abdominal pain had benign liver tumors (three adenomas and one focal nodular hyperplasia). Among the remaining six patients, four underwent liver resection for the treatment of colorectal liver metastases, three of which had undergone preoperative chemotherapy. The other two cases were one patient with metastasis from a testicular teratoma and the other with metastasis from a gastrointestinal neuroectodermal tumor. RESULTS: The average length of stay was five days (range 4–7 days). Of the seven patients who underwent resections of segments II/III, two presented postoperative complications: one developed a seroma and the other a collection of abdominal fluid who underwent percutaneous drainage, antibiotic therapy, and blood transfusion. Furthermore, the three patients who underwent major resections had postoperative complications: two developed anemia and received blood transfusions and one had biloma and underwent percutaneous drainage and antibiotic therapy. CONCLUSIONS: The use of the linear stapler in hepatectomies was efficient and at lower costs, making it suitable for use whenever EG is not available. The size of the LCS stapler shaft is more suitable for en bloc transection of the left lateral segment of the liver, which is thinner than the right one. Further studies are needed to evaluate the safety of LCS for large liver resections and resections of tumors located in the right hepatic lobe.

RESUMO RACIONAL: A morbidade das ressecções hepáticas está relacionada a sangramento intraoperatório e fístulas biliares pós-operatórias. O grampeador Endo-GIA (EG) em ressecções hepáticas está bem estabelecido, mas o seu custo é elevado, limitando seu uso. O grampeador de corte linear (LCS) é um dispositivo com menor custo. OBJETIVOS: Relatar ressecções hepáticas abertas, empregando o LCS para transecção do parênquima hepático e grampeamento em bloco de vasos e ductos biliares. MÉTODOS: Dez pacientes foram incluídos no estudo. Quatro pacientes com dor abdominal importante apresentavam tumores hepáticos benignos (três adenomas e um hiperplasia nodular focal). Dentre os demais seis pacientes, quatro foram submetidos à ressecção hepática para o tratamento de metástases hepáticas colorretais, sendo que três deles haviam sido submetidos à quimioterapia pré-operatória. Os dois outros casos foram um paciente com metástase de teratoma testicular e o outro com metástase de tumor neuroectodérmico gastrointestinal. RESULTADOS: O tempo médio de internação foi de 5 dias (variação=4-7 dias). Dos sete pacientes submetidos a ressecções dos segmentos II/III, dois apresentaram complicações pós-operatórias: um paciente desenvolveu seroma e o outro uma coleção de fluido abdominal submetido a drenagem percutânea, antibioticoterapia e transfusão de sangue. Além disso, os três pacientes submetidos a ressecções maiores tiveram complicações pós-operatórias: dois pacientes desenvolveram anemia e receberam transfusões de sangue e um paciente apresentou biloma e foi submetido a drenagem percutânea e antibioticoterapia. CONCLUSÕES: O emprego do grampeador linear nas hepatectomias foi eficiente e a custos mais baixos, tornando-o adequado para uso sempre que EG não estiver disponível O tamanho da haste do grampeador LCS é mais adequado para a transecção em bloco do segmento lateral esquerdo do fígado, que é mais fino que o direito. Novos estudos são necessários para avaliar a segurança do LCS para grandes ressecções hepáticas e ressecções de tumores localizados no lobo hepático direito.

ABSTRACT The objective was to verify if the primary root emission can be recommended as a vigor test for soybean seeds. For this, five lots of varieties ANTA 82, NA7337 and BRS1074IPRO were evaluated by first count, germination, emergence, emergence speed index and tetrazolium tests. In the root protrusion test at 20, 25 and 30 ºC, two evaluation criteria were adopted: primary root emission precocity index (PREPI) and percentage of seeds that emitted the primary root (PRE). The seeds counted were those with a primary root equal to or greater than 2 mm, every 12 h from the installation of the test until 120 h. The design was completely randomized and means were compared, within each evaluation time, using the Scott-Knott test at 5% probability. Pearson’s linear correlation was performed for PREPI and PRE with emergence. PREPI was not considered efficient. For the PRE, at 20 ºC, there was a correlation at 72 h, for the three varieties. At 25 ºC there was a correlation for a period of 36 h for ANTA 82 and NA7337 and 60 h for BRS1074IPRO. At 30 ºC there was a correlation in the time of 36 h for the three cultivars. Considering that speed in obtaining results is important in vigor tests, it is concluded that primary root emission for 36 h after installing the test at 30 ºC is recommended as a vigor test in the quality control of soybean seeds.

RESUMEN La Generación Distribuida (DG) se convirtió en la principal inversión de los sistemas energéticos en todo el mundo. Los estudios que se aplican en DG a los países subdesarrollados han demostrado la importancia de aportar soluciones y fomentar el uso de energías renovables a pequeña escala, minimizando las pérdidas en la red energética además de aumentar la seguridad energética a través de la diversificación de las fuentes de generación. Por lo tanto, este trabajo analiza el impacto de DG en un sistema energético real en Angola basado en la prueba IEEE 14-bus, utilizando el software Matlab / Simulink, realizando el análisis del sistema con el apalancamiento de DG, principalmente en situaciones de contingencia. Como resultado se observó que, a pesar de proporcionar un aumento en la capacidad de generación, el inserto DG en la red de distribución provoca cambios en el voltaje del sistema de corte debido al cambio en los flujos activos y reactivos. La situación crítica se detecta cuando hay máxima generación en propagación con carga mínima, pueden producirse modificaciones desequilibradas en los niveles de bus de corte, así como influir en una recuperación del sistema cuando se encuentra en una situación de contingencia. Este documento tiene el objetivo de proporcionar estudios iniciales sobre el impacto causado por la introducción de DG en un sistema energético en Angola, para mostrar las necesidades de preparar el sistema para recibir esta nueva tecnología en colaboración con el desarrollo del país.

ABSTRACT Distributed Generation (DG) has become the main investment of power systems worldwide. This work analyzes the impact of DG on a power system in Angola based on the IEEE 14-bus test, using Matlab/Simulink software. As a result, it was noticed that, despite the increase in the generation capacity, DG causes changes in the voltage of the cutting system due to the change in the active and reactive flows. The critical situation is detected when there is maximum generation in scattering with minimum load, and unbalanced changes may occur in the shear levels of the bars, as well as influencing the recovery of the system when subject to a contingency situation. This work aims to provide initial studies on the impact caused by the introduction of DG in Angola, to show the need to prepare the system to receive this new technology in collaboration with the development of the country.
