ABSTRACT Lettuce (Lactuca sativa) is the most economically important leafy vegetable in Brazil, with the crisp type being the most popular among producers. However, in regions with hot climates, lettuce has production limitations due to bolting, requiring knowledge on the behavior of cultivars available on the market. Thus, the objective of the present study was to characterize the performance of crisp lettuce cultivars in terms of their productive, physiological, and postharvest quality aspects when grown under hydroponic cultivation and high temperature conditions. The assay was performed in a greenhouse and the plants were grown in a hydroponic system of DFT type. The average temperature during the experiment was 30.33 °C. The experimental design used was completely randomized with nine treatments (Veneranda, Cristina, Olinda, Mônica, Cinderela, Grand Rapids, Itapuã Super, Crocantela, and Simpson Black Seed), with four replications. The cultivars were analyzed in terms of their productive, physiological, and postharvest quality performances. The Olinda and Cristina cultivars showed the best performance in growth, physiological, and postharvest variables. However, the cultivars had distinct sensory characteristics. Bolting negatively affected gas exchange, production, and postharvest quality of lettuce cultivars Veneranda, Mônica, Grand Rapids, and Cinderela. In addition, it was observed that the pigment content was not determinant for the expression of bolting. Therefore, this study recommends the use of cultivars Olinda and Cristina for the hydroponic cultivation under high temperature conditions.

RESUMO A alface (Lactuca sativa) é a hortaliça folhosa de maior importância econômica no Brasil, sendo o tipo crespa a mais popular entre os produtores. Entretanto, em regiões de clima quente, a alface apresenta limitações de produção devido ao pendoamento precoce, exigindo o conhecimento do comportamento das cultivares disponíveis no mercado. Assim, o objetivo do presente estudo foi caracterizar o desempenho de cultivares de alface crespa quanto aos aspectos produtivos, fisiológicos e de qualidade pós-colheita, cultivadas em condições de cultivo hidropônico e alta temperatura. O ensaio foi conduzido em condição de casa de vegetação, sendo as plantas cultivadas em sistema hidropônico tipo DFT. A temperatura média durante o experimento foi de 30,33 °C. O delineamento experimental utilizado foi o inteiramente casualizado com nove tratamentos (Veneranda, Cristina, Olinda, Mônica, Cinderela, Grand Rapids, Itapuã Super, Crocantela e Simpson Black Seed) e quatro repetições. As cultivares foram analisadas quanto ao seu desempenho produtivo, fisiológico e de qualidade pós-colheita. As cultivares Olinda e Cristina apresentaram melhor desempenho nos parâmetros de crescimento, fisiológicos e pós-colheita. Entretanto, estas cultivares apresentaram características sensoriais distintas. Verificou-se que o pendoamento precoce afetou negativamente as trocas gasosas, a produção e a qualidade pós-colheita das cultivares de alface Veneranda, Mônica, Grand Rapids e Cinderela. Além disso, observou-se que o teor de pigmentos não foi determinante para a expressão do pendoamento. Portanto, este estudo recomenda o uso das cultivares Olinda e Cristina para o cultivo hidropônico em condições de alta temperatura.

Abstract This research assessed the efficiency of chemically modified tannins as coagulants for water treatment. Tannins from Anacardium occidentale (cashew tree) and Mimosa caesalpiniifolia (‘sabiá’) barks and seedless fruits of Anadenanthera colubrina (‘angico’) and Pityrocarpa moniliformis (‘angico de bezerro’) were evaluated after cationization to remove turbidity from water. After extraction, the total solids content (TSC), Stiasny index (SI), and total condensed tannins content (TCC) of the tannins extracts were determined. Extracted tannins were converted into powders and cationized. Then, the cationized tannins' effectiveness on water turbidity removal, sedimentation time, and effect on pH were assessed. Three concentrations of each type of tannin were used to evaluate flocculant efficiency: 50, 100, and 150 mg L-1. Although the P. moniliformis extract had a higher TSC value (56.06%), it presented the lowest SI (0.42%) and TTC (0.23%) values. M. caesalpiniifolia had the lowest TSC (9.18%) and the highest SI (91.27%), while Ac occidentale stood out with the highest TCC (19.83%). All species have shown potential for tannin production and efficiently removed turbidity at all concentrations. However, only A. occidentale, at a concentration of 100 mg L-1, presented a nephelometric turbidity unit of 2.4, reaching the potability standards required by international specifications and, therefore, being indicated for water treatment. treatment cashew tree ‘sabiá sabiá (‘sabiá’ ‘angico angico (‘angico’ bezerro bezerro’ extraction TSC, , (TSC) SI, (SI) (TCC determined Then removal time 50 15 L1.

Resumo O presente trabalho teve como objetivo avaliar a eficiência de taninos quimicamente modificados como coagulantes para tratamento de água. Os taninos das cascas de Anacardium occidentale (cajueiro) e Mimosa caesalpiniifolia (sabiá) e dos frutos sem sementes de Anadenanthera colubrina (angico) e Pityrocarpa moniliformis (angico de bezerro) foram avaliados após cationização para remover a turbidez da água. Após a extração, os extratos de taninos tiveram o teor de sólidos totais (TST), o índice de Stiasny (IS) e o teor de taninos totais condensados (TCT). Os taninos extraídos foram convertidos em pó e cationizados. Em seguida, avaliou-se a eficácia dos taninos cationizados na remoção da turbidez e o tempo de sedimentação além do efeito no pH da água. Para avaliar a eficiência dos taninos cationizados como floculantes foram utilizadas três concentrações de cada tipo de material: 50, 100 e 150 mg L-1. Embora o extrato de P. moniliformis tenha apresentado maior valor de TST (56,06%), apresentou os menores valores de IS (0,42%) e TCT (0,23%). Os taninos da casca de M. caesalpiniifolia apresentou o menor TST (9,18%) e o maior IS (91,27%), enquanto os derivados de A. occidentale se destacaram pelo maior TCT (19,83%). Todas as espécies demonstraram potencial para produção de taninos e foram eficientes em remover a turbidez da água em todas as concentrações. Porém, apenas o A. occidentale, na concentração de 100 mg L-1, apresentou unidade de turbidez nefelométrica de 2,4, atingindo os padrões de potabilidade exigidos pelas especificações internacionais e, portanto, sendo indicado para tratamento de água. cajueiro (cajueiro sabiá (sabiá angico bezerro extração TST, , (TST) (IS TCT. .

ABSTRACT The genus Psidium is recognized for its economic value and the species that produce essential oils with notable biological activities. This study investigated the characteristics of the essential oil from the leaves of Psidium myrtoides and Psidium cattleyanum under different drying temperatures. We aimed to understand how drying temperatures affect the yield and composition of the essential oil, as well as its biological activity. The oils obtained from the leaves of P. myrtoides and P. cattleyanum dried in an oven at 40°C showed the highest yields (0.86% and 1.07%, respectively). β-caryophyllene was the major compound in all essential oils of P. myrtoides and P. cattleyanum, except in the oil extracted from P. myrtoides leaves dried at room temperature, where the major compound was α-bisabolol (14.46%). Different phytotoxic effects were observed using the emulsion of these oils in bioassays with Lactuca sativa and Sorghum bicolor, which were associated with the chemical composition and synergy of the identified compounds. The essential oil emulsion from leaves dried at room temperature of both species showed greater phytotoxic activity in the bioassays. Thus, optimizing drying conditions to maximize yield and synergy of compounds from the essential oils of P. myrtoides and P. cattleyanum is an important step in developing environmentally friendly natural agrochemicals. activities P 40C C 40 0.86% 086 0 86 (0.86 107 1 07 1.07% respectively. respectively . respectively) βcaryophyllene β caryophyllene αbisabolol α bisabolol 14.46%. 1446 14.46% 14 46 (14.46%) bicolor Thus agrochemicals 4 0.86 08 8 (0.8 10 1.07 144 14.46 (14.46% 0.8 (0. 1.0 14.4 (14.46 0.

RESUMO O gênero Psidium é reconhecido pelo seu valor econômico e por suas espécies produtoras de óleos essenciais, com notáveis atividades biológicas. Este estudo investigou as características do óleo essencial das folhas de Psidium myrtoides e Psidium cattleyanum sob diferentes temperaturas de secagem. O objetivo foi entender como as temperaturas de secagem afetam o rendimento e a composição do óleo essencial, além de sua atividade biológica, utilizando bioensaios com Lactuca sativa e Sorghum bicolor para avaliar os efeitos fitotóxicos. Os óleos obtidos das folhas de P. myrtoides e P. cattleyanum secas em estufa a 40°C apresentaram os maiores rendimentos, sendo 0,86% e 1,07%, respectivamente. O β-cariofileno foi o composto majoritário com maior área relativa em todos os óleos essenciais de P. myrtoides e P. cattleyanum, exceto, no óleo extraído de folhas secas em temperatura ambiente de P. myrtoides, cujo composto majoritário foi o alfa-bisabolol (14,46%). Assim como a alteração do perfil químico dos óleos essenciais, houve diferentes efeitos fitotóxicos utilizando a emulsão desses óleos. Esses efeitos, foram associados a composição química e a sinergia destes compostos. A emulsão de óleo essencial de folhas secas à temperatura ambiente de ambas as espécies mostrou maior atividade fitotóxica nos bioensaios. Assim, a otimização das condições de secagem para maximizar o rendimento e a sinergia dos compostos dos óleos essenciais de P. myrtoides e P. cattleyanum é um passo importante no desenvolvimento de agroquímicos naturais e sustentáveis. biológicas biológica P 40C C 40 rendimentos 086 0 86 0,86 107 1 07 1,07% respectivamente βcariofileno β cariofileno exceto alfabisabolol alfa bisabolol 14,46%. 1446 14,46% . 14 46 (14,46%) sustentáveis 4 08 8 0,8 10 1,07 144 14,46 (14,46% 0, 1,0 14,4 (14,46 1, 14, (14,4 (14, (14 (1 (

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

Resumen Hoy en día la medición de la dinámica respiratoria está infravalorada en el ámbito clínico y en la vida diaria de un sujeto, y sigue representando un reto desde el punto de vista técnico y médico. En este artículo proponemos un concepto para medir algunos de sus parámetros, como la frecuencia respiratoria (FR), utilizando cuatro sensores inerciales. Se realizaron dos experimentos diferentes para validar el concepto. Analizamos la colocación más adecuada de cada sensor para evaluar esas características y estudiamos la fiabilidad del sistema para medir parámetros anormales de la respiración (taquipnea, bradipnea y retención de la respiración). Por último, realizamos mediciones en pacientes posCOVID-19, algunos de ellos con alteraciones respiratorias después de más de un año del diagnóstico. Los resultados experimentales mostraron que el sistema propuesto podría utilizarse potencialmente para medir la dinámica respiratoria en el ámbito clínico. Además, mientras que la FR puede calcularse fácilmente con cualquier sensor, otros parámetros deben medirse con un sensor en una posición determinada.
Abstract Nowadays, the measurement of respiratory dynamics is underrated at clinical setting and in the daily life of a subject, still representing a challenge from a technical and medical point of view. In this article we propose a concept to measure some of its parameters, such as the respiratory rate (RR), using four inertial sensors. Two different experiments were performed to validate the concept. We analyzed the most suitable placement of each sensor to assess those features and studied the reliability of the system to measure abnormal parameters of respiration (tachypnea, bradypnea and breath holding). Finally, we measured post-COVID-19 patients, some of them with breath alterations after more than a year of the diagnosis. Experimental results showed that the proposed system could be potentially used to measure the respiratory dynamics at clinical setting. Moreover, while RR can be easily calculated by any sensor, other parameters need to be measured with a sensor in a particular position.

ABSTRACT For many fish species, prolonged fasting is part of their life cycle, as there are seasonal fluctuations in the quantity and quality of food available in their natural habitat. These animals use endogenous reserves during periods of food scarcity and recover when resources become available again. We evaluated the effect of a prolonged fasting period on indicators of body reserve use, growth performance and intestinal integrity of the Amazonian serrasalmid Piaractus brachypomus. We distributed 66 juveniles (68.6 ± 2.2 g) in 11 tanks. The treatment consisted of 30 days fasting followed by 45 days refeeding and the control of 75 days normal feeding with 5 replicates (one tank with six fish). The six individuals in the 11th tank were used for baseline measurements. Blood parameters, muscle lipid concentration, hepatosomatic and mesenteric fat indices, somatic growth parameters and intestinal villi morphology were measured every 15 days. Glucose, triglycerides, cholesterol, total protein, the mesenteric fat and hepatosomatic indices, weight gain, specific growth rate, condition factor and total biomass decreased significantly during fasting compared to the control, but all except body condition recovered during refeeding. The length and perimeter of the intestinal villi was significantly lower during fasting compared to the control. The feeding protocol allowed P. brachypomus to mobilize part of their body reserves during fasting, however, in general, refeeding was sufficient to restore their body needs and growth performance compatible with that of continuously fed animals. species cycle habitat again 6 68.6 686 68 (68. 22 2 2. g 1 tanks 3 4 7 one fish. . fish) th measurements concentration indices Glucose triglycerides cholesterol protein gain rate P however general 68.

RESUMO Muitas espécies de peixe suportam jejum prolongado como parte do seu ciclo de vida, devido a flutuações na quantidade e qualidade de alimentos disponíveis em seu habitat natural. Esses animais utilizam reservas endógenas durante períodos de escassez de alimentos e se recuperam quando voltam a estar disponíveis. Avaliamos o efeito de jejum prolongado sobre indicadores de uso de reservas corporais, desempenho e integridade intestinal no serrasalmídeo amazônico Piaractus brachypomus. Distribuímos 66 juvenis (68,6 ± 2,2 g) em 11 tanques. O tratamento consistiu em 30 dias de jejum seguidos de 45 dias de realimentação, e o controle de 75 dias de alimentação contínua, com 5 repetições (um tanque com seis peixes). Os seis indivíduos do 11º tanque foram usados para medidas basais. Parâmetros sanguíneos, concentração de lipídios musculares, índices de gordura hepatossomática e mesentérica, parâmetros de crescimento somático e morfologia das vilosidades intestinais foram medidos a cada 15 dias. Glicose, triglicerídeos, colesterol, proteína total, índices hepatossomático e de gordura mesentérica, ganho em peso, taxa de crescimento específico, fator de condição e biomassa total diminuíram significativamente durante o jejum em comparação com o controle, mas todos, exceto a condição corporal, recuperaram-se durante a realimentação. O comprimento e o perímetro das vilosidades intestinais foram significativamente menores durante o jejum em comparação com o controle. O protocolo de alimentação permitiu que P. brachypomus mobilizasse parte de suas reservas corporais durante o jejum, porém, em geral, a realimentação foi suficiente para repor suas necessidades corporais e o desempenho compatível com o de animais alimentados continuamente. vida natural 6 68,6 686 68 (68, 22 2 2, g 1 tanques 3 4 7 contínua um peixes. peixes . peixes) º basais sanguíneos musculares mesentérica Glicose triglicerídeos colesterol peso específico todos corporal recuperaramse recuperaram P porém geral continuamente 68, (68 (6 (

Abstract Background Although there are several ways to assess pain in dementia, there is still a need for tools with better items to assess the presence of pain intensity in these individuals. Objective To validate to Brazilian version of the “Pain Intensity Measure for Persons with Dementia – PIMD-p. Methods Older adults, all demented with impaired verbal communication and exposed to potentially painful situations, were selected from an outpatient clinic and long-term care facility (LTCF). The PIMD-p was applied independently by 2 researchers (E1 and E2) on the same day. Within 14 days, the instrument was reapplied by one of the 2 researchers (E3). The pain intensity reported by participants' caregivers and LTCF nurses were recorded on a verbal numeric pain scale. For the statistical analysis, Cronbach's Alpha, Spearman's Coefficient and intraclass correlation Index were calculated. Results A total of 50 older individuals were selected (mean age 86 years), majority with musculoskeletal pain. The PIMD-p demonstrated good internal consistency according to Cronbach's α (0.838), excellent intra and interobserver reproducibility (0.927 and 0.970, respectively; p < 0.001), and convergent validity (strong significant correlations between reported pain intensities and pain indicators on the PIMD-p (except for expressive eyes; corr = 0.106 and p = 0.462). A ROC curve was plotted to determine the best cut-off for the PIMD-P, and a score of 7.5 predicted moderate-to-severe pain, with 77.8% sensitivity and 95.7% specificity (p < 0.001). Conclusion The PIMD-p showed satisfactory psychometric properties for measuring intensity of pain in demented older adults with impaired verbal communication. dementia Pain PIMDp.

Resumo Antecedentes Embora existam várias formas de estimar a dor na demência ainda há necessidade de ferramentas com melhores itens para avaliação da presença e intensidade da dor nesses indivíduos. Objetivo Analisar as propriedades psicométricas de uma ferramenta de avaliação da dor em idosos dementados, a “Pain Intensity Measure for Persons with Dementia Portuguese - PIMD-p”. Métodos Idosos expostos a situações potencialmente dolorosas, sendo esses dementados e com prejuízo na comunicação verbal, foram selecionados em uma unidade ambulatorial e uma instituição de longa permanência, em São Paulo. A PIMD-p foi aplicada por 2 pesquisadores (E1 e E2), de forma separada, num mesmo dia, e, com intervalo de no máximo 14 dias, essa foi reaplicada por apenas um deles (E3), e ainda, foi obtida a intensidade álgica inferida pelos cuidadores dos idosos participantes. Na análise estatística foram utilizados o Alfa de Cronbach, o Coeficiente de Spearman e o Índice de Correlação Intraclasses. Resultados Selecionada uma amostra de 50 idosos com média de idade de 86 anos, a maioria portadora de demência moderada e de dor de origem musculoesquelética. Apuradas para a PIMD-p uma boa consistência interna, segundo o alfa Cronbach (0,838); excelentes reprodutibilidades intra e interobservador (0,927 e 0,970, respectivamente; p < 0,001); e uma validade convergente, essa última obtida com as fortes e significativas correlações entre as intensidades dolorosas inferidas e os indicadores de dor do instrumento em estudo (exceto para o indicador “olhar expressivo”; corr = 0,106 e p = 0,462).

Abstract Physaloptera Rudolphi, 1819 is a genus of nematodes that includes approximately 100 species parasitic in vertebrates around the world. From these, approximately 30 occur in the Neotropical region, with nine reported from neotropical reptiles. Physaloptera spp. are recognized by their distinct morphology of the apical end and characters of the reproductive system. However, despite the fact that the morphological characters for species diagnosis have been firmly established, we frequently find identification problems regarding poorly detailed descriptions and poorly preserved specimens. These may lead to taxonomic incongruencies. Physaloptera retusa (Rudolphi, 1819) is the most common species of the genus and has been reported from several species of neotropical reptiles. Based on our reexaminations of nematode specimens identified as P. retusa from different museum collections, we provide a detailed redescription including the type material, voucher specimens and new specimens recovered currently and showed in this study with new morphological data obtained using light and scanning electron microscopy tools.

Abstract Banana preserve is produced by mixing the puree of the fruit with sucrose and organic acids. However, concerns about body esthetics or health reasons have encouraged the search for low-calorie products. Therefore, the objective of this study was to evaluate the effect of calcium chloride (CaCl2), carrageenan gum, and low methoxyl pectin (LM-pectin) on the physicochemical and sensory characteristics of sugar-free banana preserves. By using a central composite rotational design (CCRD) of 2³ + 6 axial points + 4 central points, we obtained 18 formulations that were further tested. Lower CaCl2 concentrations (0.54% to 0.61%) resulted in preserves with lower pH and more vivid color. The increased concentration of LM-pectin (1.40% to 1.64%) resulted in formulations with a yellowish-red hue and with lower moisture, thus, reducing the flavor and purchase intention of the product. Higher concentrations of carrageenan gum (1.04% to 1.15%) decreased the perception of banana preserve aroma. Therefore, concentrations of CaCl2 ranging from 0.54% to 0.61%, carrageenan gum ranging from 0.74% to 0.89% and LM-pectin ranging from 1.40% to 1.64% resulted in sugar-free banana preserves with ideal sweetness and consistency and were, therefore, more acceptable. acids However lowcalorie calorie products Therefore CaCl2, CaCl , (CaCl2) LMpectin LM (LM-pectin sugarfree sugar free CCRD (CCRD 2 1 tested 054 0 54 (0.54 0.61% 061 61 color 140 40 (1.40 164 64 yellowishred yellowish red moisture thus product 1.04% 104 04 (1.04 1.15% 115 15 aroma 0.54 074 74 0.74 089 89 0.89 1.40 1.64 therefore acceptable (CaCl2 05 5 (0.5 0.61 06 14 (1.4 16 1.04 10 (1.0 1.15 11 0.5 07 7 0.7 08 8 0.8 1.4 1.6 (CaCl (0. 0.6 (1. 1.0 1.1 0. 1.

ABSTRACT Piptocephalis includes mycoparasitic fungi, mainly targeting mucoralean species. Until now, there has been no compilation of data on the taxonomy and geographic distribution of Piptocephalis, which is a barrier to the proper identification of species of this genus by taxonomists. The present study provides an overview of Piptocephalis with taxonomic and occurrence data, in addition to reporting P. graefenhanii and P. xenophila for the first time in South America. Both species were observed parasitizing Mucor spp. The P. graefenhanii was observed growing on paca dung and P. xenophila was observed on guinea-pig dung in Recife, northeastern Brazil. Aspects of their morphology are discussed and a key for the genus is presented. fungi now taxonomists P America spp guineapig guinea pig Recife Brazil presented

Background Eucalyptus is the primary cultivated wood species in Brazil, covering 7.5 million hectares. Weed competition in eucalyptus plantations reduces yield and increases operational costs. FuturaGene/Suzano has developed genetically modified (GM) eucalyptus varieties with glyphosate herbicide tolerance (HT) as a modern tool for improving weed management practices in plantations. The first event received regulatory approval for commercial deployment in 2021. However, the introgression of a new GM trait into eucalyptus, a non-isogenic species, cannot be achieved through selfing or backcrossing. To overcome this limitation and expedite the introgression of HT into the breeding population, multiple GM events were generated, in various genetic backgrounds and genomic locations, enabling simultaneous crossing with numerous elite parents. Objective To characterize the newly developed HT GM eucalyptus events and assess their safety for the environment and wood production. Methods HT GM eucalyptus events were subjected to genome sequencing and glyphosate tolerance testing. Biosafety analyses and environmental impact assessments were conducted through field trials in various eucalyptus cultivation regions, comparing the HT GM eucalyptus with conventional clones. Results The new events proved highly tolerant to glyphosate and displayed different genomic insertion sites. No adverse effects on non-target organisms were observed, and there were no significant differences in the soil microbiota or decomposition profile.Conclusions: The HT GM events have been proven to be safe, posing a low risk to the environment, humans, and animals. Consequently, these HT GM eucalyptus varieties can be confidently utilized for wood production.

Abstract The purpose of this paper was to avaliate of the concentration of hydrocolloids (low methoxyl pectin [LMP], guar gum [GG], and carrageenan gum [CG]) in low-calorie orange jellies in order to maximize the amount of bioactive compounds and antioxidant capacity, and to study the influence on degradation these compounds. A mixture design with seven tests was used to analyze the total phenolic compounds, ascorbic acid (vitamin C) and antioxidant capacity (ABTS, DPPH and β-carotene/linoleic acid methods). The results were analyzed by response surface methodology and the Scott-Knott mean test at a significance level of 5% (p ≤ 0.05). In general, the regions containing 0.5% GG and 0.5% GC had higher levels of the variables under study, and this combination preserved the bioactive compounds and antioxidant activity of jellies in relation to that of orange juice. low LMP, LMP , [LMP] GG, [GG] CG [CG] lowcalorie calorie vitamin C ABTS, ABTS (ABTS βcarotene/linoleic βcarotenelinoleic β carotene/linoleic carotene linoleic methods. methods . methods) ScottKnott Scott Knott 5 p 0.05. 005 0.05 0 05 0.05) general 0.5 juice [LMP [GG [CG βcarotene carotenelinoleic 00 0.0 0.

Abstract Chemical and pharmacological potentials of botanical species found in the Cerrado are well-known and widely studied. Chemical diversity of secondary metabolites produced by plants that belong to this Brazilian biome has triggered several studies in the fields of farming, pharmaceutical and cosmetic industries. Therefore, this study aimed at evaluating the chemical composition of essential oils (EOs) from fresh leaves of three species found in the Brazilian Cerrado: Cardiopetalum calophyllum Schltdl. (EO-CC), Campomanesia adamantium (Cambess.) O. Berg (EO-CA) and Protium ovatum Engl. (EO-PO) and at determining their anti-Malassezia furfur and anti-inflammatory activities. Both GC-FID and GC-MS showed that the most abundant chemical class of the oils was the one of sesquiterpene hydrocarbons. The major constituents identified in EO-CC were germacrene D (34.9%) and bicyclogermacrene (26.8%). EO-CA exhibited mainly germacrene D (21.7%) while EO-PO had high concentrations of germacrene D (25.0%) and γ-muurolene (18.6%). EOs were tested by the broth microdilution method on 96-well microplates and exhibited satisfactory activity against M. furfur, i. e., EO-CA had MIC = 375 µg/mL while EO-CC and EO-PO had MIC = 750 µg/mL. The chemotaxis model, which was used for evaluating their anti-inflammatory activity, showed that EOs exhibited effective results: C. calophyllum (EO-CC; IC50 = 24.4 µg/mL), C. adamantium (EO-CA; IC50 = 15.7 µg/mL) and P. ovatum (EO-PO; IC50 = 32.5 µg/mL). In short, biological activities of EO-CC, EO-CA and EO-PO, such as anti-Malassezia furfur and anti-inflammatory ones, were investigated and described for the first time. wellknown well known studied farming industries Therefore (EOs Schltdl EOCC, EOCC EO CC , (EO-CC) Cambess.

Water-soluble organic carbon (WSOC) makes up a large mass fraction of the organic carbon in the aerosol and can influence important cloud processes in the atmosphere. The capacity of WSOC to form metallic complexes with transition metals is well known; however, its influence on the aerosol of urban areas in the Amazon region is not very well known. In this study, we investigated the relationship between WSOC, black carbon (BC), levoglucosan (LEV) and transition metals (Fe, Cu and Mn) present in the PM2.5 (particles with a diameter smaller than 2.5 µm) of an urban environment during the dry season in the central Amazon. Oxalic acid (C2) was used to identify the influence of transition metals on WSOC. The mean mass concentration value of the PM2.5 was 14.72 μg m-3 (2.11-31.68 μg m-3). The WSOC made up 58.34% of the PM2.5 mass, followed by BC (20.28%), and LEV (2.62%). The WSOC showed significant correlation with the transition metals analyzed (> 0.56), especially Mn with C2 (linear coefficient (R2) = 0.74). A multiple linear regression with WSOC, BC and LEV showed a strong linear correlation between them (R2 = 0.86), indicating the influence of biomass burning and vehicle traffic on the organic aerosol.

BACKGROUND The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has become a major concern contributing to increased morbidity and mortality worldwide. OBJECTIVES Here we describe the replacement of the Gamma variant of concern (VOC) with Delta in the western Brazilian Amazon. METHODS In this study, we analysed 540 SARS-CoV-2 positive samples determined by qualitative real-time RT-PCR selected in the state of Rondônia between June and December 2021. The positive cohort was sequenced through next-generation sequencing (NGS) and each sample was quantified using real-time RT-qPCR, the whole genome sequence was obtained, SARS-CoV-2 lineages were classified using the system Pango and the maximum likelihood (ML) method was used to conduct phylogenetic analyses. FINDINGS A total of 540 high-quality genomes were obtained, where the Delta VOC showed the highest prevalence making up 72%, with strain AY.43 being the most abundant, while the Gamma VOC was present in 28%, where the P.1 strain was the most frequent. In this study population, only 32.96% (178/540) had completed the vaccination schedule. MAIN CONCLUSIONS This study highlighted the presence of Gamma and Delta variants of SARS-CoV-2 in RO. Furthermore, we observed the replacement of the Gamma VOC with the Delta VOC and its lineages.
