Process of Establishment And In Vitro Development of Simaba Cedron Planch Seedlings. (Simaroubaceae)

Simaba cedron, popularly known as "cedron", is largely used for fever and snake bites. Its seeds are used in the treatment of stomach problems and liver infections. The fruits are used for the treatment of pain and malaria while its bark is an antispasmodic. Simaba cedron is generally propagated through seeds, but with limited success, as the low viability of same restricts its propagation. In view of such difficulty, it becomes necessary the study for adequate conditions for the large scale production of these seedlings. Being it known that in several species, the use of micropropagation has made it possible to obtain a large amount of disease-free and more homogeneous seedlings, in reduced time and physical space, in comparison with conventional propagation methods, the objective of this work was to analyze the effect of two culture media on the production of aseptic parent plants as a first step in the development of a micropropagation protocol for Simaba cedron. The seeds were collected from a matrix plant located in the Amazon Biotechnology Center (CBA), in Manaus/AM. The experiment was installed at the Vegetable Tissue Culture Laboratory, where the  explants were desinfected and grown in culture medium  according to Murashige & Skoog (MS) and in Wood Plant Medium (WPM), during 60 days. The disinfestation rate obtained was 75% and, of the disinfested seeds, 100% germinated. The cultivation medium that was more favorable to the cultivation of simaba was the MS, where the multiplication rate was of 8.0: 1, whose seedlings reached, in average, 4.8 cm and 75% of rooting

Characterization and selection of torch ginger for cut flower

Torch ginger, Etlingera elatior, is among the most cultivated tropical flower of its genus. Its great acceptability in the market led researchers to improve production characteristics and to adapt it for commercialization. This study aimed to characterize 10 genotypes of torch ginger in order to select and recommend them as cut flower. The experiment ran from Jan 2014 to Dec 2016 in Paulista, Brazil and nine agro-morphological characteristics were evaluated to build a grading system that determined their suitability for cut flower. The IAC 26 and IAC 34 genotypes were classified as poorly suitable, for they presented fresh mass exceeding 237 g. They also presented less than 19 flower stems per clump and only one month with ≥1 floral stem produced in 2015. The genotypes IAC 1, IAC 2, IAC 3, IAC 11, IAC 13 and the cultivar IAC Prumirim were classified as suitable, although they obtained intermediate scores for most of the evaluated criteria. The genotype IAC 41 and the cultivar IAC Camburi were classified as very suitable for cut flower, beginning of flowering period at 12 months, produce 33.25 and 41.20 flower stem per clump, respectively, and present seven months with production of more than one floral stem per clump in 2016, achieving maximum scores from most of the evaluated characteristics

Effect of processing on nutritional value of the mandim fish (Arius spixii)

Com o objetivo de avaliar o efeito do beneficiamento sobre o valor nutricional do peixe mandim (Arius spixii) comercializado em Maceió-AL, determinaram-se nas suas formas in natura e beneficiada (salgado-seco) a composição centesimal, valor calórico, cloretos, perfil de ácidos graxos e colesterol, sendo também analisada a ocorrência de óxidos de colesterol. Os resultados obtidos para o mandim in natura e beneficiado, respectivamente, de umidade (70,13% e 40,31%), proteínas (51,73% e 38,07%, base seca), carboidratos (4,67% e 2,24%, base seca), calorias (486 kcal/100g e 367 kcal/100g, base seca), ácidos graxos (poliinsaturados 14,54% e 15,49%, ômega-3 8,51% e 6,51%), colesterol (82,66 mg/100g e 61,30 mg/100g) e óxidos (7-cetocolesterol 8,31 µg/g e 17,90 µg/g), permitiram concluir que o beneficiamento favoreceu alterações significativas no valor nutricional do mandim.In an attempt to analyze how processing enhances the nutritional value of the mandim fish (Arius spixii) marketed in Maceió-AL, Brazil, the following nutritional components were determined in fresh and processed (salted-dried) fish: centesimal composition, calorie count, chloride, fatty acid and cholesterol profile. The presence of cholesterol oxides was also investigated. Respective results for fresh and processed mandim fish were: moisture (70.13% and 40.31%), proteins (51.73% and 38.07%, dried), carbohyrdrates (4.67% and 2.24%, dried), calories (486 kcal/100g and 367 kcal/100g, dried), fatty acids (polyunsaturared 14,54% and 15,49%, ômega-3 8,51% and 6,51%), cholesterol (82.66 mg/100g and 61.30 mg/100g) and oxides (7-ketocholesterol 8.31 µg/g and 17.90 µg/g). These figures clearly showed that processing led to significant change in the nutritional value of the mandim fish

OS PRINCIPAIS FATORES DA ECMO NA UTI PEDIÁTRICA

Although Extracorporeal Membrane Oxygenation (ECMO) provides many benefits in the treatment of critically ill pediatric intensive care patients, having many connectors and access points in the circuit is not without risks. In view of this, the objective was to investigate the complications that are susceptible to pediatric patients using ECMO in the Pediatric Intensive Care Unit and the respective interventions for the recovery of the state of health. To this end, a narrative review of the literature was carried out in the LILACS, MEDLINE and SCIELO databases, in the period 2018-2023. With the results obtained in research, there is evidence of a great interest in Intensive Care Medicine in improving the approach to pediatric patients undergoing ECMO, due to the risk of complications, such as, for example, the presence and/or formation of clots, gas embolism and /or failure of the oxygenator when performing the technique. Such events are associated with the interactions of the blood with the artificial surfaces of the circuit and changes in the blood flow pattern, in addition to a greater number of adverse events related to the prolonged treatment time, but which can be prevented by prioritizing monitoring in two lines of action: monitoring the technique, including cannula care, oxygenator output, oxygenator rotations, oxygenator pressures, circuit temperature, coagulation index, gasometric evaluation in the oxygenator; and patient monitoring by assessing vital parameters and capillary blood glucose, the neurological system, diuresis and blood loss, positioning, as well as ventilatory and gasometric parameters.Embora a Oxigenação por Membrana Extracorpórea (ECMO) proporcione muitos benefícios no tratamento de pacientes pediátricos sob cuidados intensivos em estado crítico, o fato de possuir muitos conectores e pontos de acesso no circuito não encontra-se isenta de riscos. Em vista disso, objetivou-se investigar as complicações que encontram-se suscetíveis os pacientes pediátricos em uso da ECMO na Unidade de Terapia Intensiva Pediátrica e as respectivas intervenções para a recuperação do estado de saúde. Para tanto, realizou-se uma revisão narrativa da literatura nas bases de dados LILACS, MEDLINE e SCIELO, no período de 2018-2023. Com os resultados obtidos em pesquisa, evidencia-se um grande interesse na Medicina Intensiva em melhorar a abordagem do paciente pediátrico submetido à ECMO, pelo risco de complicações como, por exemplo, presença e/ou formação de trombos, embolia gasosa e/ou falha do oxigenador durante a execução da técnica. Esses eventos estão associados a interações do sangue com superfícies artificiais do circuito e alterações no padrão de fluxo sanguíneo, além de um maior número de eventos adversos relacionados à duração prolongada do tratamento, mas que podem ser retidos priorizando o monitoramento em dois itinerários de tratamento.ação: técnica de monitoramento, incluindo manutenção da cânula, fluxo do oxigenador, rotações do oxigenador, pressões do oxigenador, temperatura do circuito, índice de coagulação, avaliação gasométrica no oxigenador; e monitoramento do paciente por meio da avaliação de parâmetros vitais e glicemia capilar, sistema neurológico, diurese e perda sanguínea, posicionamento, bem como parâmetros ventilatórios e gasometria arteria

Preliminary observation of the use of sodium bicarbonate solution as an adjunct in the treatment of coronavirus 2019 disease (COVID-19): prognosis improvement in patients requiring intensive care / Observação preliminar do uso de solução de bicarbonato de sódio como coadjuvante no tratamento da doença coronavírus 2019 (COVID-19): melhora do prognóstico na necessidade de terapia intensiva

Introduction: This study aimed to evaluate the use of sodium bicarbonate solution as an adjunct in the treatment of critically ill patients in an intensive care unit (ICU). Methods: A group of 76 patients were followed up, of which 44 received treatment with a sodium bicarbonate (NaHCO3) solution along with the conventional treatment, and 32 patients used only the conventional treatment. Results: In patients treated, there was an improvement in radiological findings, a decrease in opacity and bilateral consolidations, as well as reduced length of stay in the ICU, and mortality. Conclusion: The use of NaHCO3 solution as an adjunct in the treatment of COVID-19 improved prognosis compared to conventional treatment. 

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

Caracterização ecológica e estrutural de macrófitas em reservatórios no Estado de Pernambuco

As macrófitas aquáticas desempenham importante função na manutenção e equilíbrio dos ambientes aquáticos, sendo considerada como a principal fonte produtora de matéria orgânica. Servem de abrigo e/ou alimentação para diversos tipos de organismos, atuam na despoluição dos ambientes aquáticos, na produção de biomassa, no controle de erosão hídrica, no melhoramento físico e nutricional do solo, e na ciclagem de nutrientes, entre outros. Apesar da grande ocorrência de macrófitas nos ecossistemas aquáticos, são poucos os trabalhos de pesquisa, realizados sobre plantas aquáticas, principalmente do ponto de vista taxonômico, florístico e/ou ecológico em Pernambuco. O território pernambucano proporciona a existência de sucessivas paisagens geográficas, dando lugar a três zonas fitogeográficas bem definidas: zona da mata/litoral, agreste e sertão. O presente estudo teve como objetivos: a) caracterizar os reservatórios de Apipucos, Prata, Tapacurá (zonada mata/litoral), Jucazinho, Tabocas, Mundaú (zona do agreste), Arcoverde e Jazigo (zona do sertão) situado no estado de Pernambuco, através da identificação dos táxons existentes e suas respectivas formas biológicas; b) examinar se existe diferença na riqueza dos reservatórios entre os períodos sazonais (chuvoso/seco); e c) a partir da composição florística em oito reservatórios no estado de Pernambuco, e em diferentes regiões fitogeográficas (zona da mata/litoral, agreste e sertão) é possível identificar a relação de quais variáveis abióticas (transparência da água, temperatura do ar, temperatura da água, oxigênio dissolvido, saturação de oxigênio, condutividade, turbidez, pH, fósforo total, fósforo total dissolvido, ortofosfato e nitrogênio total) poderão influenciar na distribuição das espécies de macrófitas. Foram realizadas coletas de macrófitas aquáticas e amostras da água para as análises físico-químicas em todos os reservatórios, em duas épocas do ano (seco e chuvoso), no período de abril de 2008 a fevereiro de 2010. Na margem litorânea do reservatório foram demarcados 5 transectos (em posição perpendicular a margem) cada um com 10 m de comprimento com espaçamento de 10 m entre eles. O ponto zero do transecto foi apartir da região litorânea (margem inundável) do reservatório. As coletas foram realizadas alternadamente a cada 2 m do transecto, em parcelas de PVC de 50 x 50 cm, totalizando 25 parcelas por reservatório em cada período sazonal. Foram identificadas 65 espécies, distribuídos em 29 famílias. As famílias que apresentaram maior representatividade de espécies foram: Poaceae (14 spp.), Cyperaceae (6 spp.), Fabaceae-Faboideae e Onagraceae com quatro espécies cada. A forma biológica mais comum foi a emergente com (53 spp.), seguidas de flutuante livre (6 spp.), submersa fixa (4 spp.) e flutuante fixa (2 spp.). Os resultados mostraram que, a riqueza de espécies foi relativamente elevada, quando comparada a outros estudos em reservatórios. Os maiores índices de diversidade de Shannon foram registrados para os reservatórios de Apipucos (zona da mata/litoral), Tabocas e Mundaú (zona do agreste), e Arcoverde e Jazigo (zona do sertão). De acordo com o índice de estado trófico, os reservatórios foram classificados como eutróficos. Foi observado também que as macrófitas estão distribuídas nos diferentes reservatórios de maneira diferenciada, e que não foi comprovada a exclusividade de espécies por regiões fitogeográficas. Contudo, o período seco e chuvoso interfere efetivamente na diversidade de espécies. Análise de Correspondência Canônica (CCA) permitiu separar as espécies nos reservatórios baseados nas variáveis abióticas ortofosfato, turbidez, pH, transparência da água e condutividade. Contudo, não foi verificada correlação entre as espécies de macrófitas e os fatores abióticos.Aquatic macrophytes play an important role in the maintenance and equilibrium of aquatic environment, being considered as the main source that produces organic matter. They are shelter and/or food for many types of organisms and help cleaning aquatic environments, also acting on biomass production, water erosion control, soil physical and nutritional improvement and on nutrient cycling, among others. Despite the great occurrence of macrophytes on aquatic ecosystems, there are few researches dedicated to aquatic plants in Pernambuco, mainly under the taxonomic, floristic and ecological point of view. Pernambuco’s territory allows the existence of successive geographical landscapes, giving place to three well-defined phytogeografical zones: zona da mata/coast, agreste and sertão. This study aimed to: a) characterize the reservoirs of Apipucos, Prata, Tapacurá (zona da mata/coast), Jucazinho, Tabocas, Mundaú (agreste zone), Arcoverde e Jazigo (sertão zone) placed in the state of Pernambuco, by identifying the existent taxa and their respective biological forms; b) examine the existence of differences on reservoir’s richness between seasonal periods (rainy/dry); and c) coming from the floristic composition in eight reservoirs in the state of Pernambuco, and in different phytogeografical regions (zona da mata/coast, agreste and sertão) it is possible to identify which related abiotic variables (water transparence, air temperature, water temperature, dissolved oxygen, oxygen saturation, conductivity, turbidity, pH, total phosphorous, total dissolved phosphorous, orthophosphate and total nitrogen) can influence the distribution of macrophyte species. Aquatic macrophyte and water sample collections were performed for physic-chemical analyses in all reservoirs for both dry and rainy seasons in the period from April, 2008 to February, 2010. On the reservoir’s coastal margin 5 transects were established (perpendicular to the margin), each one with 10 m and 10 m distant from each other. The beginning of each transect was the coastal region (floodable margin) of the reservoir. Colections were performed alternately each 2m of the transect in PVC 50 x 50 cm parcels, totalizing 25 parcels in each reservoir for each seasonal period. A total of 65 species were identified, distributed in 29 families. The most representative families were: Poaceae (14 spp.), Cyperaceae (6 spp.), Fabaceae-Faboideae and Onagraceae, each one with 4 species. The most common biological form was the emergent (53 spp.), followed by free floating (6 spp.), submerjed (4 spp.) and rooted floating (2 spp.) The results showed that species richness was relatively high when compared to other researches in reservoirs. The highest Shannon diversity indexes were registered for the reservoirs of Apipucos (zona da mata/ coast), Tabocas and Mundaú (agreste zone), and Arcoverde and Jazigo (sertão zone). According to the trophic state index the reservoirs were classified as eutrophic. It was also observed that macrophytes are distributed in the different reservoirs in a distinct way and there is no species exclusivity for phytogeografical regions. However, the dry and rainy periods effectively influences species diversity. The Canonical Correspondence analysis (CCA) allowed the separation of species in the reservoirs based on the abiotic variables orthophosphate, turbidity, pH, water transparence and conductivity. However, no correlation was found among macrophyte species and abiotic factors
