The essential oil extracted from Anemia tomentosa (EOAT) has shown larvicidal potential against Aedes aegypti, based on methods in vitro and in silico. Chromatographic and spectrometric techniques (gas chromatography-mass spectrometry (CG-MS), gas chromatography-flame ionization detector (GC-FID)), as well as mono and bidimensional nuclear magnetic resonance spectroscopy (NMR) were used to assess 10 essential oil components. Chemical composition of essential oil comprised 87.51% sesquiterpenes, with emphasis on presilphiperfolan-1-ol (42.13%) and silphiperfol-5-ene (19.47%). Larvicidal assay conducted in vitro with EOAT has evidenced potential cytotoxic activity up to 48 h exposure to it; mortality rate observed for A. aegypti larvae exposed to essential oil reached 100%. Study conducted in silico with chemical compounds deriving from the herein investigated plant species has evidenced its potential to inhibit acetylcholinesterase in A. aegypti. Activity of triquinane sesquiterpenes ranging from -6.8 to -8.2 kcal mol-1 stood out in comparison to that of temephos (-7.5 kcal mol-1). Chemical compounds identified in the investigated essential oil presented low human and environmental toxicity, as observed in absorption, distribution, metabolism and excretion, and toxicity (ADMETox) predictions.

ABSTRACT The hidden hunger for Se in the world population is well known. As a strategy to address this issue, this study aimed to biofortify onion (Allium cepa L.), since it is a condiment vegetable consumed by different economic classes and is widely used in the food industry. To this end, Se doses (0, 10, 25, 50, 100 and 200 g ha-1) and application forms (soil and foliar) were evaluated on the biofortification of the bulb and crop yield. The Se source was sodium selenate. Via soil, Se was applied together with NPK fertilizer in the pre-transplantation of the seedlings. Via foliar application, Se was sprayed 77 d after seedlings were transplanted. The Se increased yield up to 99 g ha-1, which was 14.7% higher than the yield obtained in the crop not fertilized with Se. Foliar application of Se was more efficient than soil application in the biofortification of onion, although both were effective. With the dose that promoted the highest yield, the Se concentrations reached 0.487 and 0.317 mg Se kg-1 in onion dry mass, when the supply was made via foliar and soil applications, respectively. The increase in Se supply did not influence bulb quality, as demonstrated by the macro- and micronutrients content and pungency.

La distorsión de la imagen corporal es una alteración en la percepción del cuerpo que puede repercutir en la salud. Este estudio busca estimar, entre las mujeres participantes del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) que viven en Bahía, Brasil, la prevalencia de precisión y distorsión de la imagen corporal e investigar asociaciones con las características socioeconómicas, el estilo de vida y la busca de atención ginecológica. Participaron 609 mujeres que tenían entre 50 y 69 años que contestaron los cuestionarios aplicados cara a cara entre 2012 y 2014. Se utilizó la escala de siluetas de Stunkard para investigar la percepción precisa o distorsionada para más o menos peso. El cociente de riesgo relativo (RR) se calculó a través de regresión logística multinomial utilizando el Stata 13. La mayoría de los participantes tiene una perspectiva precisa del propio cuerpo (53,7%). Entre las personas con percepción distorsionada hay una tendencia a la distorsión para menos peso (38,1%). En el análisis de regresión multinomial, las variables raza/color y escolaridad permanecieron asociadas con la distorsión para menos peso, siendo la primera positivamente asociada con la distorsión para menos peso entre las mujeres pardas (RR = 1,89; IC95%: 1,13-3,16) y negras (RR = 2,10; IC95%: 1,25-3,55), mientras la segunda entre las mujeres que estudiaron hasta la enseñanza secundaria (RR = 1,65; IC95%: 1,18-2,33).

Body image distortion is an alteration in the perception of the body that can have repercussions on health. This study aims to estimate the prevalence of body image accuracy and distortion among women participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) living in Bahia State, Brazil, and to investigate associations with socioeconomic characteristics, lifestyle, and gynecological care seeking. A total of 609 women aged 50 to 69 years participated in the study, who answered face-to-face questionnaires from 2012 to 2014. The Stunkard silhouette scale was used to investigate accurate or distorted perception for more or less weight. The relative risk ratio (RR) was calculated by multinomial logistic regression using Stata 13. Most participants have an accurate perception of their own bodies (53.7%). Among those with distorted perception, there is a tendency to distort towards less weight (38.1%). In the multinomial regression analysis, the variables race/skin color and education remained associated with the distortion towards underweight. The race/skin color variable was positively associated with the distortion towards underweight among Mixed-race women (RR = 1.89; 95%CI: 1.13-3.16) and black (RR = 2.10; 95%CI: 1.25-3.55), while the education variable among those with up to high school education (RR = 1.65; 95%CI: 1.18-2.33). There were no associations with the other variables or with distortion for more weight. The results contribute to explaining the relationships between body image perception and socioeconomic factors, revealing that women of different races/skin colors and varying educational levels are influenced in different ways by social discourses, impacting the perception of their body image. health ELSABrasil ELSA Brasil (ELSA-Brasil State Brazil characteristics lifestyle seeking 60 5 6 facetoface face 201 2014 RR 13 53.7%. 537 53.7% . 53 7 (53.7%) 38.1%. 381 38.1% 38 1 (38.1%) analysis raceskin race skin Mixedrace Mixed 1.89 189 89 95%CI 95CI CI 95 1.133.16 113316 1.13 3.16 3 16 1.13-3.16 2.10 210 2 10 1.253.55, 125355 1.25 3.55 , 25 55 1.25-3.55) 1.65 165 65 1.182.33. 118233 1.18 2.33 18 33 1.18-2.33) factors racesskin races discourses 20 53.7 (53.7% 38.1 (38.1% 1.8 8 9 133 1.133.1 11331 113 1.1 316 3.1 1.13-3.1 2.1 21 253 1.253.55 12535 125 1.2 355 3.5 1.25-3.55 1.6 182 1.182.33 11823 118 233 2.3 1.18-2.33 53.

This study aimed to investigate the occurrence of photolysis of two relevant antibiotics, sulfamethoxazole and trimethoprim, when present in a Waste Stabilization Pond and its disinfection under tropical irradiance. The influence of pH and matrix components, and the generation of photoproducts during solar exposure were evaluated. The pH-dependent speciation of antibiotics had a greater influence on the photolysis of antibiotics than the water matrix, with higher photodegradation at pH 4.1 than at pH 7.2. Trimethoprim was more susceptible to indirect photolysis, indicated by the steeper influence of the photosensitizers nitrate and humic acid compared to sulfamethoxazole. The photoproducts generated were persistent to photolysis and remained present in the samples up to 70 h irradiation. Wastewater disinfection was achieved after 70 h of solar exposure. Nonetheless, the exposure time required to remove at least 50% of sulfamethoxazole was on average 29 h and of trimethoprim 83 h, at the natural pH of the matrix (pH 7.2). Given that the residence time in Waste Stabilization Pond is 41 h, which corresponds to a maximum of 26 h solar irradiation, the exposure time in Waste Stabilization Pond is not sufficient to completely photodegrade antibiotics or disinfect the effluent, demanding further treatment. irradiance components evaluated pHdependent dependent 4 1 4. 72 7 2 7.2 irradiation Nonetheless 50 8 . 7.2) effluent treatment 7. 5

This review presents data regarding the occurrence of antibiotics in several aqueous matrices in Brazil reported in the last twelve years (from 2010 to 2022). Despite limited research on the topic, Brazil has the highest number of published data on antibiotics in surface water (SW) among Latin American countries. However, these studies primarily focused on the southern and southeastern regions, providing an incomplete picture of antibiotic occurrence in the aquatic environment of the country. Data from 24 papers show the detection of 23 antibiotics in 5 aquatic matrices, including drinking water, ranging from 0.13 ng L-1 to 37.30 μg L-1. Occurrence in SW was the most reported, and sulfamethoxazole was the antibiotic most prevalent and concentrated in this matrix (7112.4 ng L1). Besides the fact that antibiotics are only partially removed in sewage treatment plants, in Brazil, only 55.8% of the sewage generated is collected, and 80.8% of the collected sewage is treated, which aggravates the release of antibiotics to the aquatic environment. This poses a significant concern due to potential harm to non-target organisms and antibiotic-resistant bacteria proliferation, worsening global antimicrobial resistance. Given this scenario, regular monitoring to assess the presence of antibiotics and resistant bacteria is crucial, enabling timely interventions and appropriate mitigation measures. 201 2022. 2022 . 2022) topic (SW countries However regions country 2 013 0 13 0.1 L1 L 1 L- 3730 37 30 37.3 L1. 1. 7112.4 71124 7112 4 (7112.

RESUMO Landoltia punctata é uma espécie de lentilha-d’água originária da Índia, mas que atualmente tem registro em todos os continentes, à exceção da Antártida. A espécie tem interesse econômico, sendo usada em fitorremediação, mas principalmente por seu grande potencial invasor biológico. Aqui reportamos o primeiro registro dessa espécie para a região Amazônica, ampliando sua distribuição conhecida e chamar a atenção para a potencial perda da biodiversidade no tipo de ambiente em que a espécie foi registrada. Estudos futuros deveriam focar no potencial competitivo e controle populacional de L. punctata na região. lentilhadágua lentilha d água Índia continentes Antártida econômico fitorremediação biológico Amazônica registrada L

ABSTRACT Landoltia punctata is a species of duckweed originating from India, but has been recorded in all continents, except Antarctica. It is of economic interest, being used in phytoremediation, but mainly due to its high invasive potential. Here we report the first record of this species in the Amazon region, both expanding its known distribution and raising awareness about the potential losses of biodiversity that may occur in the kind of environment where the species was registered. Future studies should focus on the competitive potential and population control of L. punctata in the region. India continents Antarctica interest phytoremediation region registered L

Abstract Cowpea is a leguminous plant belonging to the fabaceae family cultivated in the North and Northeast regions of Brazil, with productive potential. Among the abiotic factors, water deficiency is one of the main environmental limitations that influence agricultural production in the world. The objective of this work was to study the relative water content and osmoregulators of cowpea plants subjected to water stress. The experiment was carried out in a greenhouse at the Universidade Federal Rural da Amazônia (UFRA, Belém, PA), cowpea plants BR-17 Gurguéia Vigna unguiculata (L.) Walp were used. The experimental design was completely randomized (DIC) in a 2 × 2 factorial scheme, two water conditions (control and water deficit) and two times of stress (four and six days of water suspension), with 7 replications, totaling 28 experimental units. The water deficit affected plants, causing a reduction in relative water content (69.98%), starch (12.84% in leaves and 23.48% in roots) and carbohydrates (84.34%), and an increase in glycine-betaine, sucrose (114.11% in leaves and 18.71% in roots) and proline (358.86%) at time 2. The relative water content was negatively affected by water conditions, with a decrease in relation to the interaction of the aerial part and the root system. Therefore, greater metabolic responses were noted in plants that were subjected to stress treatment at time 2 (6 days).

Resumo O feijão-caupi é uma planta leguminosa pertencente à família das Fabaceae cultivada nas regiões Norte e Nordeste do Brasil, com potencial produtivo. Entre os fatores abióticos, a deficiência hídrica é uma das principais limitações ambientais que influenciam a produção agrícola no mundo. O objetivo do trabalho foi estudar o conteúdo relativo de água e os osmorreguladores de plantas de feijão-caupi submetidas ao estresse hídrico. O experimento foi conduzido em casa de vegetação da Universidade Federal Rural da Amazônia (UFRA, Belém, PA), foram utilizadas plantas de feijão-caupi BR-17 Gurguéia Vigna unguiculata (L.) Walp. O delineamento experimental foi inteiramente casualizado (DIC) em esquema fatorial 2 × 2, duas condições hídricas (controle e déficit hídrico) e dois tempos de estresse (quatro e seis dias de suspensão hídrica), com 7 repetições, totalizando 28 unidades experimentais. O estresse hídrico afetou as plantas, provocando redução no conteúdo relativos de água (69,98%), amido (12,84% nas folhas e 23,48% nas raízes) e carboidratos (84,34%), e aumento na glicina-betaína, sacarose (114,11% nas folhas e 18,71% nas raízes) e prolina (358,86%) no tempo 2. O conteúdo relativo de água foi afetado negativamente pelas condições hídricas, com diminuição em relação à interação da parte aérea e do sistema radicular. Diante disso, notou-se maiores respostas metabólicas nas plantas que foram submetidas ao tratamento de estresse no tempo 2 (6 dias). feijãocaupi feijão caupi Brasil produtivo abióticos mundo UFRA, UFRA (UFRA Belém PA, PA , PA) BR17 BR 17 BR-1 L.

Na análise de regressão multinomial, permaneceram associadas à distorção para menos peso as variáveis raça/cor e escolaridade, sendo que a primeira foi positivamente associada à distorção para menos peso entre as pardas (RR = 1,89; IC95%: 1,13-3,16) e pretas (RR = 2,10; IC95%: 1,25-3,55), enquanto a segunda entre aquelas com escolaridade até o Ensino Médio (RR = 1,65; IC95%: 1,18-2,33). Não houve associações quanto às demais variáveis, nem com distorção para mais peso. Os resultados contribuem para a explicação das relações entre percepção da imagem corporal e fatores socioeconômicos, revelando que mulheres de raça/cor diferentes e variados níveis de escolaridade são influenciadas de formas distintas pelos discursos sociais, o que impacta a percepção da sua imagem corporal.

Body image distortion is an alteration in the perception of the body that can have repercussions on health. This study aims to estimate the prevalence of body image accuracy and distortion among women participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) living in Bahia State, Brazil, and to investigate associations with socioeconomic characteristics, lifestyle, and gynecological care seeking. A total of 609 women aged 50 to 69 years participated in the study, who answered face-to-face questionnaires from 2012 to 2014. The Stunkard silhouette scale was used to investigate accurate or distorted perception for more or less weight. The relative risk ratio (RR) was calculated by multinomial logistic regression using Stata 13. Most participants have an accurate perception of their own bodies (53.7%). Among those with distorted perception, there is a tendency to distort towards less weight (38.1%). In the multinomial regression analysis, the variables race/skin color and education remained associated with the distortion towards underweight. The race/skin color variable was positively associated with the distortion towards underweight among Mixed-race women (RR = 1.89; 95%CI: 1.13-3.16) and black (RR = 2.10; 95%CI: 1.25-3.55), while the education variable among those with up to high school education (RR = 1.65; 95%CI: 1.18-2.33). There were no associations with the other variables or with distortion for more weight. The results contribute to explaining the relationships between body image perception and socioeconomic factors, revealing that women of different races/skin colors and varying educational levels are influenced in different ways by social discourses, impacting the perception of their body image.

Vegetable proteases have been studied as milk coagulants, and artichoke flower (Cynara cardunculus L. var scolymus) has potential coagulant action as a substitute for microbial chymosin. The objective was to perform chemical characterization of aspartic proteases from artichoke flower (Cynara cardunculus L. var scolymus) by mid-infrared spectroscopy (MIR) and analytical measurements. Artichoke flower extracts were obtained and crude thistle flower extract and microbial chymosin were used as a reference. Plant extracts and microbial chymosin were analyzed for protein concentration, proteolytic activity (PA), milk clotting activity (MCA), specificity ratio (SR), effects of pH, temperature, NaCl and CaCl2 concentration on MCA and PA and characterized by electrophoretic, spectroscopic, chromatographic and storage stability. The results indicated that the crude extract of artichoke flower showed high MCA (510.08 SU mL 1), low PA (10.50 µg mg-1), SR (48.57) and storage stability for up to 90 days under frozen. The electrophoretic profile of artichoke flower resulted in a protein band with an apparent molecular weight of 32 kDa, associated with cardosin A. Artichoke flower may be a new alternative for commercial plant proteases with active enzymes for milk coagulation. coagulants Cynara L scolymus midinfrared mid infrared MIR (MIR measurements reference PA, , (PA) MCA, (MCA) SR, (SR) pH temperature CaCl spectroscopic 510.08 51008 510 08 (510.0 1, 1 1) 10.50 1050 10 50 (10.5 mg1, mg1 mg mg-1) 48.57 4857 48 57 (48.57 9 frozen 3 kDa A coagulation (PA (MCA (SR 510.0 5100 51 0 (510. 10.5 105 5 (10. mg-1 48.5 485 4 (48.5 510.

Abstract The gladiolus is one of the most commercially important cut flowers in Mexico. It was traditionally considered a funeral flower, but its uses have now diversified to many other decorative floral arrangements due to its variety of colors and forms. All the new varieties on the market in Mexico are of foreign origin, such that the generation of new genotypes is needed. In a previous study, flowers originating from irradiated Blanca Borrega variety corms expressed different floral characteristics, shape and size; however, it is unknown whether these characters are fixed in subsequent generations. The objective of the current work was therefore to evaluate the fixed characteristics in the ornamental quality of outstanding cultivars of Blanca Borrega variety gladiolus descended from irradiation with60Co. During the fall-winter (2020-2021) period, corms of outstanding cultivars generated by distinct irradiation doses were planted in sterilized substrate to evaluate corm germination (%), plant height, number of leaves per stem, spike length (cm), combined stem and spike length (cm), number of flowers per spike, flower size (cm), number of leaves, and survival, and to categorize cut flower quality under the United Nations Economic Commission for Europe (UN/ECE) criteria. Our results indicated that the outstanding cultivar derived from the 80 Gy dose presented a Class I classification (Second quality) of the UN/ECE parameters due to its stem height and number of buds, followed by the cultivars descended from irradiation at 10, 30 and 50 Gy and the control, which were placed in Class II (Third quality). Thus, in the third generation the favorable esthetic characteristics of the outstanding cultivars remain fixed. forms origin needed study however generations with60Co withCo with Co fallwinter fall winter 20202021 2020 2021 (2020-2021 period %, % , (%) cm, cm (cm) survival UNECE UN ECE (UN/ECE criteria 8 Second buds 10 3 5 control Third quality. .

Resumo O gladíolo é uma das flores de corte mais importantes comercialmente no México. Era tradicionalmente considerada uma flor funerária, mas seus usos agora se diversificaram para muitos outros arranjos florais decorativos devido à sua variedade de cores e formas. Todas as novas variedades no mercado mexicano são de origem estrangeira, de modo que é necessária a geração de novos genótipos. Em estudo anterior, flores provenientes de rebentos irradiados da variedade Blanca Borrega expressaram diferentes características florais, forma e tamanho; no entanto, não se sabe se esses caracteres são corrigidos nas gerações subsequentes. O objetivo do presente trabalho foi, portanto, avaliar as características fixas na qualidade ornamental de cultivares destacadas de gladíolo da variedade Blanca Borrega descendentes da irradiação com 60Co. Durante o período de outono-inverno (2020-2021), rebentos de cultivares excepcionais gerados por diferentes doses de irradiação foram plantados em substrato esterilizado para avaliar a germinação do rebento (%), altura da planta, número de folhas por haste, comprimento do espigão (cm), combinado comprimento do caule e espiga (cm), número de flores por espiga, tamanho da flor (cm), número de folhas e sobrevivência, e para categorizar a qualidade da flor cortada sob os critérios da Comissão Econômica das Nações Unidas para a Europa (UN/ECE). Nossos resultados indicaram que a cultivar de destaque derivada da dose de 80 Gy apresentou classificação Classe I (Segunda qualidade) dos parâmetros UN/ECE devido à altura do caule e número de gemas, seguida pelas cultivares descendentes da irradiação aos 10, 30 e 50 Gy e o controle, que foram colocados na Classe II (Terceira qualidade). Assim, na terceira geração, as características estéticas favoráveis das cultivares de destaque permanecem fixas.

ABSTRACT Brackish waters has been increasingly used in hydroponic systems for the cultivation of vegetables. However, its use can cause significant losses in crop production. Therefore, new alternatives to enhance the tolerance of plants to salt stress are being studied, including seed priming with hydrogen peroxide (H2O2). Thus, this study aimed to assess the seed priming with H2O2 at different periods of exposure for enhancing the production, water status and pigments concentration of crisp lettuce grown under salt stress. The experiment was carried out under protected conditions, in a completely randomized design, with four replicates. The plants were cultivated in a floating hydroponic system, containing nutrient solution. Five treatments were tested: control (absence of H2O2 and absence of NaCl); salt control (absence of H2O2 and presence of 100 mM NaCl); 0.1 mM H2O2 (12 hours) + 100 mM NaCl; 0.1 mM H2O2 (24 hours) + 100 mM NaCl, and 0.1 mM H2O2 (36 hours) + 100 mM NaCl. In general, salinity reduced the height, production of the fresh and dry mass of the shoot, relative water content, and chlorophylls concentration of lettuce plants. However, the application of 0.1 mM H2O2 for 12 and 36 hours on the seeds, enhanced the growth, water status, and chlorophylls concentration of the plants. Seed priming with H2O2 at a 0.1 mM concentration for 12 hours can be recommended to increase tolerance of lettuce plants grown in a hydroponic system under salt stress. vegetables However Therefore studied H2O2.

RESUMO As águas salobras vêm sendo cada vez mais utilizadas em sistemas hidropônicos para o cultivo de hortaliças. Entretanto, seu uso pode provocar prejuízos significativos na produção das culturas. Assim, este trabalho teve como objetivo avaliar o condicionamento fisiológico de sementes com H2O2 em diferentes períodos de exposição para melhorar a produção, estado hídrico e teor de pigmentos de alface crespa cultivada sob estresse salino. O experimento foi conduzido em condições protegidas, em delineamento inteiramente casualizado, com quatro repetições. As plantas foram cultivadas em sistema hidropônico do tipo floating, contendo solução nutritiva de Furlani. Foram testados cinco tratamentos: controle (ausência de H2O2 e ausência de NaCl); controle salino (ausência de H2O2 e presença de 100 mM NaCl); 0,1 mM H2O2 (12 horas) + 100 mM NaCl; 0,1 mM H2O2 (24 horas) + 100 mM NaCl e 0,1 mM H2O2 (36 horas) + 100 mM NaCl. Em geral, a salinidade reduziu a altura, a produção de massa fresca e seca da parte aérea, o teor relativo de água e o teor de clorofilas das plantas de alface. No entanto, a aplicação de 0,1 mM de H2O2 por 12 e 36 horas na semente melhorou o crescimento, o estado hídrico e o teor de clorofila das plantas. O condicionamento de sementes com H2O2 na concentração de 0,1 mM por 12 horas pode ser recomendado para aumentar a tolerância de plantas de alface cultivadas em sistema hidropônico sob estresse salino. hortaliças Entretanto culturas Assim HO H H2O protegidas casualizado repetições floating Furlani tratamentos NaCl) 10 01 0 1 0, (1 24 (2 (3 geral altura aérea entanto 3 crescimento ( 2

ABSTRACT Mangrove ecosystems are sensitive to oil, as spills can impair developmental processes of mangrove vegetation. Since the 2010s, the Brazilian equatorial margin, more specifically the Pará-Maranhão Basin and the mouth of the Amazonas River, has been affected by oil runoff from urban activities and the increased risk from exploratory deepwater drilling for oil extraction. Dispersal of mangrove propagules occurs during the tidal cycles, when the presence of tensors in the water can affect germination. We analyzed the effects of diesel oil on the germination of propagules of the two most common mangrove species in the region, Laguncularia racemosa and Avicennia germinans, in six treatments of diesel oil in the water (0.5%, 1%, 1.5%, 2%, 3% and 4%) and a diesel-free control. The response variables were germinability (G%), mean germination time, mean germination speed and the germination speed index (GSI). G% and GSI in L. racemosa propagules differed significantly between the control and all treatments (G% and GSI < 10% in the 3% treatment). Propagules of A. germinans were more resistant, and the physiological variables did not differ significantly among treatments and control (G% > 90% in all treatments). Our results indicate that, at the germination stage, L. racemosa was more susceptible than A. germinans to contamination by automotive diesel oil. vegetation 2010s s margin ParáMaranhão Pará Maranhão River extraction cycles region 0.5%, 05 0 5 (0.5% 1 1% 15 1.5% 2 2% 3 4% 4 dieselfree free G%, G , (G%) time GSI. .

RESUMO Os ecossistemas de manguezais são sensíveis ao óleo, pois os derramamentos podem prejudicar os processos de desenvolvimento da vegetação de mangue. Desde a década de 2010, a margem equatorial brasileira, mais especificamente a Bacia do Pará-Maranhão e a foz do Rio Amazonas, vem sendo afetada pelo vazamento de petróleo proveniente de atividades urbanas e pelo aumento do risco de perfurações exploratórias em águas profundas para extração de petróleo. A dispersão dos propágulos do manguezal ocorre durante os ciclos das marés, quando a presença de tensores na água pode afetar a germinação. Analisamos os efeitos do óleo diesel na germinação de propágulos de duas espécies de mangue mais comuns na região, Laguncularia racemosa e Avicennia germinans, em seis tratamentos de óleo diesel na água (0,5%, 1%, 1,5%, 2%, 3% e 4%) e um controle sem óleo diesel. As variáveis resposta foram germinabilidade (G%), tempo médio de germinação, velocidade média de germinação e índice de velocidade de germinação (IVG). G% e IVG dos propágulos de L. racemosa diferiram significativamente entre o controle e todos os tratamentos (G% e GSI < 10% no tratamento 3%). Os propágulos de A. germinans foram mais resistentes e as variáveis fisiológicas não diferiram significativamente entre tratamentos e controle (G% > 90% em todos os tratamentos). Nossos resultados indicam que, no estágio de germinação, L. racemosa foi mais suscetivel que A. germinans à contaminação por óleo diesel automotivo. 2010 brasileira ParáMaranhão Pará Maranhão Amazonas marés região 0,5%, 05 0 5 (0,5% 1 1% 15 1,5% 2 2% 3 4% 4 G%, G , (G%) IVG. .

La microscopía electrónica de barrido-espectroscopía dispersiva de energía (SEM-EDS) mostró partículas de 14 - 69 µm con una composición de 54.3 % de carbono, 45.4 % de oxígeno y 0.15 % de potasio. La dispersión dinámica de luz (DLS) mostró partículas de tamaño nanométrico (120 nm). La resonancia magnética nuclear (NMR) y la difracción de rayos X (XRD) exhibieron la cristalinidad del almidón como tipo B (34.73 %) y la reflectancia total atenuada por espectroscopia infrarroja transformada de Fourier (FTIR - ATR) mostró los grupos funcionales distintivos de la glucosa.

Abstract The objective of this study was to evaluate the physicochemical, morphological, structural, and thermal properties of starch recovered from Solanum tuberosum residual of chips industry in Mexico using advanced instrumental techniques. The residual potato was collected from a chips production company and the starch obtained by aqueous extraction. The starch presented a content of carbohydrates of 87.79 %, proteins (1.18 %), lipids (0.15 %), ashes (0.26 %), and amylose (24.35 %). The water absorption capacity was 1.0163 g g-1, solubility (30.17 - 46.65 %), swelling (2.31 - 8.69 g g-1). Thermal analyzes showed a starch gelatinization about 61.7 - 90 ºC with a maximum weight loss at 288.1 °C. The scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) showed particles of 14 - 69 µm with a composition of 54.3 % carbon, 45.4 % oxygen, and 0.15 % potassium. The dynamic light scattering (DLS) showed particles of nanometric size (120 nm). The nuclear magnetic resonance (NMR) and X-Ray diffraction (XRD) exhibited the crystallinity of the starch as type B (34.73 %) and the Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) showed the functional groups distinctive of the glucose.

Research to identify plant bioactive compounds led to the evolution of extraction methods. This study optimized ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) to extract the flavonoids of Croton grewioides Baill. species contributing to characterize the polar extract profile and understand the antioxidant potential of these plant constituents. The use of experimental design and statistical treatments enabled the determination of the ideal conditions for each technique. The extracts of five accessions of C. grewioides were obtained under the optimized extraction conditions and were analyzed using ultra high-resolution mass spectrometry (FT-Orbitrap MS) operating at negative ionization mode for flavonoids detection. The accurate experimental mass obtained to the main compounds was used to attribute the molecular formula. Chemical structures of the main compounds detected were proposed using structure data bases. Chemometric analysis were performed with two FT-Orbitrap MS spectra samples using the identified metabolites and, the antioxidant activity data, showing that for this species the MAE was most effective in extracting the antioxidant compounds. It was possible to propose the structures for forty compounds in the C. grewioides extracts, demonstrating the excellent performance of the FT-Orbitrap MS in providing information on the chemical profile of polar compounds in plant extracts. methods ultrasoundassisted ultrasound assisted UAE (UAE microwaveassisted microwave (MAE Baill constituents technique C highresolution high resolution FTOrbitrap FT Orbitrap detection formula bases
