In the Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

Abstract Osteoma is a benign osteogenic neoplasm characterized by gradual growth. Commonly, it manifests in the craniofacial region, marked by the proliferation of compact and/or cancellous bone. Despite its frequent occurrence, peripheral osteoma’s precise etiology and pathogenesis remain unknown. Post-surgical excision recurrence is rare, and malignant transformation has yet to be documented. This study aims to detail an unusual case of na 11-year-old male patient presenting with a solitary peripheral osteoma in the right retromolar trigone region, a previously unreported site. The patient was initially asymptomatic, but after one month, the lesion induced facial asymmetry and discomfort while chewing. Successful surgical intervention resulted in the lesion's removal, and after 1 year of monitoring, no signs of recurrence were observed. This paper also highlights the peripheral osteoma’s clinical, radiographic, surgical, and histopathological features, as well as its differential diagnoses

Resumo O osteoma é uma neoplasia osteogénica benigna de crescimento lento que ocorre comumente na região craniofacial e é caracterizada pela proliferação de osso compacto e/ou esponjoso. Apesar da sua ocorrência frequente, a etiologia e a patogénese do osteoma periférico permanecem desconhecidas. A recorrência pós-excisão cirúrgica é rara, e a transformação maligna ainda não foi documentada. O objetivo deste trabalho foi descrever um caso incomum de paciente do sexo masculino de 11 anos que apresentava um osteoma periférico solitário na região do trígono retromolar direito, um local previamente não relatado. O paciente estava inicialmente assintomático, mas após um mês, a lesão induziu assimetria facial e desconforto ao mastigar. Uma intervenção cirúrgica bem-sucedida resultou na remoção cirúrgica da lesão, e após 1 ano de monitoramento não foram observados sinais de recidiva. Este artigo também destaca as características clínicas, radiográficas, cirúrgicas e histopatológicas do osteoma periférico, assim como o diagnóstico diferencial

ABSTRACT Soil salinization negatively affects the growth and yield of economically valuable crops such as soybeans. New technologies are being developed to minimize the damage caused by saline stress and improve crop performance. Therefore, the use of biostimulants in agriculture may offer an alternative method to mitigate the deleterious effects of salinity. Extracts of the seaweed, Ascophyllum nodosum and humic substances (fulvic acids) are commonly used. Therefore, this study aimed to evaluate the action of a biostimulant composed of A. nodosum seaweed extract and fulvic acid applied at different phenological stages on the biometric, biochemical, and physiological parameters of soybeans (Glycine max) subjected to irrigation with saline water. The experimental design used was completely randomized in a 3 × 2 + 2 factorial scheme, referring to three applications of the biostimulant at different soybean phenological stages: V3, V3R1, and V3R1R4, two levels of electrical conductivity of irrigation water (ECw): 0.5 (S0) and 5.0 dS m-1 (S1), two additional controls, one with a positive control (PC) and the other with a negative control (NC). The experiment had five replicates with one plant per plot. The results of this study suggest that the application of the biostimulant can mitigate the harmful effects of salt stress in soybeans. The results obtained with V3R1 application in the parameters stem diameter, leaf area, shoot dry mass, electrolyte leakage, and chlorophyll b represent greater efficiency in mitigating the harmful effects of salinity in soybean cultivation. performance Therefore acids A biometric biochemical Glycine max scheme V3 V VR R V3R1R4 VRR ECw (ECw) 05 0 5 0.

RESUMO Processo de salinização do solo afeta negativamente o crescimento e o rendimento de culturas economicamente valiosas, como a soja. Com o objetivo de minimizar os danos causados pelo estresse salino e melhorar o desempenho das culturas, novas tecnologias estão sendo desenvolvidas. Neste contexto, o uso de bioestimulantes na agricultura pode oferecer uma alternativa para mitigar os efeitos deletérios da salinidade. O extrato da alga Ascophyllum nodosum e substâncias húmicas (ácidos fúlvicos) são comumente empregados. Portanto, o estudo teve como objetivo avaliar a ação de um bioestimulante composto pelo extrato da alga marinha A. nodosum e ácidos fúlvicos aplicados em diferentes estádios fenológicos sobre parâmetros biométricos, bioquímicos e fisiológicos da soja (Glycine max) submetida à irrigação com água salina. O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial 3 x 2 + 2, referente a três aplicações do bioestimulante em diferentes estádios fenológicos da soja: V3, V3R1 e V3R1R4, dois níveis de condutividade elétrica da água de irrigação (CEa): 0,5 (S0) e 5,0 dS m-1 (S1), dois controles adicionais, um com controle positivo (PC) e outro com controle negativo (NC). O experimento contou com cinco repetições e uma planta por parcela. Os resultados deste estudo sugerem que a aplicação do bioestimulante pode ser uma alternativa na mitigação dos efeitos nocivos do estresse salino em soja. Os resultados foram obtidos com a aplicação V3R1 nos parâmetros diâmetro do caule, área foliar, massa seca da parte aérea, extravasamento de eletrólitos e clorofila b representam maior eficiência na mitigação dos efeitos nocivos da salinidade no cultivo da soja. valiosas desenvolvidas contexto empregados Portanto A biométricos Glycine max salina V3 V VR R V3R V3R1R4 VRR CEa (CEa) 05 0 5 0, S0 S (S0 50 5, m1 m 1 m- S1, S1 , (S1) adicionais PC (PC NC.

ABSTRACT: This study evaluated the effect of the co-feeding (C) period on the growth and survival of larvae of the yo-yo loach Botia lohachata ornamental species during the weaning period from live food (LF) to inert food (IF). The breeders were subjected to induced spawning using crude pituitary homogenate. A total of 2,400 larvae were used with an average initial weight of 0.39 ± 0.09 mg and an average total length of 4.08 ± 0.21 mm, from a single breeding pair. The live food was newly hatched nauplii of Artemia franciscana, and the inert diet was a commercial ration with 55% crude protein and two particle sizes (142-350 µm and 350-500 µm). As the first food, all larvae received A. franciscana during the first six days, except for the fasting (NC) and inert food (IF) groups. The following co-feeding strategies were employed: C4 = 4 days of co-feeding, C8 = 8 days of co-feeding, C12 = 12 days of co-feeding, and LF = Artemia during the entire experimental period. The longest period with live food promoted better larval growth rates. The specific growth rate of larvae fed live food during the entire period (LF) was higher than that of the other groups, followed by the co-feeding strategies. There was no effect (P > 0.01) on larval survival in the LF, C12, C8, and C4 groups, which ranged from 41% to 53% after 30 days. Treatment R resulted in high mortality and low growth, suggesting that live food should be the first food source for B. lohachata larvae. ABSTRACT cofeeding co feeding C (C yoyo yo (LF IF.

RESUMO: Este estudo teve como objetivo avaliar o efeito do período de co-alimentação (C) no crescimento e sobrevivência de larvas da espécie ornamental Botia lohachata durante o período de desmame de alimento vivo (LF) para alimento inerte (IF). Os reprodutores foram submetidos à desova induzida com homogeneizado de hipófise. Foram utilizadas 2.400 larvas com peso inicial médio de 0,39 ± 0,09 mg e comprimento total médio de 4,08 ± 0,21 mm, de um único casal reprodutor. O alimento vivo foi náuplios recém-eclodidos de Artemia franciscana, e a dieta inerte foi uma ração comercial com 55% de proteína bruta e dois tamanhos de partículas (142-350 µm e 350-500 µm). Como primeiro alimento, todas as larvas receberam A. franciscana durante os primeiros seis dias, exceto os grupos jejum (NC) e alimento inerte (IF). As seguintes estratégias de co-alimentação foram empregadas: C4 = 4 dias de co-alimentação, C8 = 8 dias de co-alimentação, C12 = 12 dias de co-alimentação e LF = Artemia durante todo o período experimental. O maior período com alimento vivo promoveu melhores taxas de crescimento larval. A taxa de crescimento específico das larvas alimentadas com ração viva durante todo o período (LF) foi maior que a dos demais grupos, seguida das estratégias de co-alimentação. Não houve efeito (P > 0,01) na sobrevivência larval nos grupos LF, C12, C8 e C4, que variou de 41% a 53% após 30 dias. O tratamento IN resultou em alta mortalidade e baixo crescimento, sugerindo que o alimento vivo deve ser a primeira fonte de alimento para as larvas de B. lohachata.

Abstract This study evaluated the median lethal concentration of silver nanoparticles and their effects in fish tambaqui Colossoma macropomum. Therefore, an acute toxicity assay was carried out in completely randomized design evaluating six different concentrations of silver nanoparticles on blood parameters of tambaqui. The silver nanoparticles were produced by chemical reduction with polyvinyl alcohol (AgNP-PVA). The lethal concentration 50% (LC50) was estimated using probit regression. The blood was collected, analyzed and the data were submitted to T-test (dying x surviving fish) and Tukey test (surviving fish). An increase in glucose, hematocrit, total plasma protein, hemoglobin, erythrocytes, leukocytes, monocytes, and neutrophils as well as reduced MCV (mean corpuscular volume) in dying fish compared to surviving fish were observed. Survived fish exposed to 187.5 µg/L showed an increase in hematocrit, MCV, and MCH and a reduction in erythrocytes, total numbers of leukocyte, thrombocyte, lymphocyte, and neutrophil. The fish exposed to concentrations below 125 µg/L, had returned the blood parameter to baselines compared to control. The estimated LC50 was 165.09 µg/L and was classified as highly toxic for the fish tambaqui. In higher concentrations, it causes an acute respiratory toxicity, but in concentrations below 125 µg/L, the fish can adapt to the stressing agent. macropomum Therefore AgNPPVA. AgNPPVA AgNP PVA .

Abstract Transporting live fish is a common practice in fish farming, and is certainly one of the main problems that affect fish homeostasis. In this scenario, the use of natural additives has shown promise in improving fish resistance to adverse situations. This study aimed to assess the impact of Ocimum gratissimum L. essential oil (OGEO) on water quality, hematological parameters, and residue levels in the plasma, fillet, and liver of juvenile piraputanga (Brycon hilarii) during a two-hour transportation period. The fish were divided into plastic bags (4 L) and exposed to three different OGEO concentrations (10, 20, and 30 mg L-1), while a control group received no OGEO (three repetitions each). After the two-hour transportation, blood samples were collected, as well as portions of the fillet and liver for quantifying essential oil compounds, which were also measured in the plasma. Oxygen levels remained high throughout the transportation period, in all groups, while the pH decreased. Hemoglobin, MCHC, and MCH increased in fish exposed to OGEO concentrations of 20 and 30 mg L-1, compared to the control group. However, lymphocyte counts and the concentrations of essential oil compounds in plasma, fillet, and liver increased with higher OGEO concentrations. The use of 10 mg L-1 OGEO in the two-hour transport water is promising to ensure the survival and well-being of Brycon hilarii juveniles (weighing 16 g), showing to be safe and effective. The residual concentration of eugenol the major compound of OGEO in the fillet remains below the maximum limit of the recommended daily intake. farming homeostasis scenario situations L (OGEO quality parameters plasma twohour two hour period 4 ( 10, (10 3 L1, L1 1 , L-1) each. each . each) collected groups decreased Hemoglobin MCHC 2 1, However L- wellbeing being weighing g, g g) effective intake (1

Resumo O transporte de peixes vivos é uma prática comum na piscicultura, e é certamente um dos principais problemas que afetam a homeostase dos peixes e neste cenário o uso de aditivos naturais tem-se mostrado promissor para melhorar a resistência dos peixes frente a situações adversas. Este estudo teve como objetivo avaliar o impacto do óleo essencial de Ocimum gratissimum L. (OEOG) na qualidade de água, perfil hematológico e níveis de resíduos no plasma, filé e fígado de juvenis de piraputanga (Brycon hilarii) durante um período de transporte de duas horas. Os peixes foram divididos em sacos plásticos (4 L) e expostos a três concentrações diferentes de OE OG (10, 20 e 30 mg L-1) enquanto um grupo não recebeu OEOG. Cada grupo com três repetições. Após o transporte de duas horas, foram coletadas amostras de sangue, bem como de filé e do fígado para a quantificação dos compostos do óleo essencial, que também foram mensurados no plasma. Os níveis de oxigênio permaneceram elevados durante todo o período do transporte, em todos os grupos, enquanto o pH diminuiu. A hemoglobina, CHCM e HCM aumentaram nos peixes dos grupos EOOG 20 e 30 mg L-1, em comparação ao grupo controle. No entanto, a contagem dos linfócitos e as concentrações decompostos no plasma, filé e fígado aumentaram com a concentração mais elevada de OEOG. O uso de 10 mg L-1 de OGEO na água de transporte de duas horas é promissor para garantir a sobrevivência e o bem-estar dos juvenis de Brycon hilarii (pesando 16 g), mostrando-se seguro e eficaz.

Abstract Background: Coronavirus disease 2019 (COVID-19) is associated with hypercoagulability. It remains uncertain whether ongoing anticoagulation for atrial fibrillation (AF) in patients who later contract COVID-19 improves clinical outcomes. Objectives: To compare chronic oral anticoagulation with no previous anticoagulation in patients with AF who contracted a COVID-19 infection concerning the outcomes of all-cause mortality, COVID-19 mortality, intensive care unit (ICU) admission, and hospitalization. Methods: We systematically searched PubMed, Embase, and Cochrane Library for eligible studies from inception to December 2022. We included studies comparing COVID-19 outcomes in patients with versus without prior chronic anticoagulation for AF. Risk ratios (RR) with 95% confidence intervals (CI) were pooled with a random-effects model. The level of significance was set at p < 0.05. Quality assessment and risk of bias were performed according to Cochrane recommendations. Results: Ten studies comprising 1,177,858 patients with COVID-19 and AF were identified, of whom 893,772 (75.9%) were on prior chronic anticoagulation for AF. In patients with COVID-19, being on chronic anticoagulation for AF significantly reduced all-cause mortality (RR 0.75; 95% CI 0.57 to 0.99; p = 0.048; I2 = 89%) and COVID-19-related mortality (RR 0.76; 95% CI 0.72 to 0.79; p < 0.001; I2 = 0%) when compared with no prior anticoagulation. In contrast, there was no difference between groups regarding hospitalization (RR 1.08; 95% CI 0.82 to 1.41; p = 0.587; I2 = 95%) or ICU admission (RR 0.86; 95% CI 0.68 to 1.09; p = 0.216; I2 = 69%). Conclusions: In this meta-analysis, chronic anticoagulation for patients with AF who contracted COVID-19 was associated with significantly lower rates of all-cause mortality and COVID-19-related mortality as compared with no previous anticoagulation.

Resumo Fundamento: A doença por coronavírus 2019 (COVID-19) está associada à hipercoagulabilidade. Permanece incerto se a anticoagulação contínua para fibrilação atrial (FA) em pacientes que posteriormente contraem COVID-19 melhora os desfechos clínicos. Objetivos: Comparar a anticoagulação oral crônica com ausência de anticoagulação prévia em pacientes com FA que contraíram uma infecção por COVID-19 em relação aos desfechos de mortalidade por todas as causas, mortalidade por COVID-19, admissão em unidade de terapia intensiva (UTI) e hospitalização. Métodos: Buscamos sistematicamente no PubMed, Embase e Cochrane Library estudos elegíveis desde o início até dezembro de 2022. Incluímos estudos que compararam desfechos de COVID-19 em pacientes com e sem anticoagulação crônica prévia para FA. Foram agrupadas razões de risco (RR) com intervalos de confiança (IC) de 95% por meio de um modelo de efeitos aleatórios. O nível de significância foi estabelecido em p < 0,05. As avaliações da qualidade e do risco de viés foram realizadas de acordo com as recomendações da Cochrane. Resultados: Foram identificados 10 estudos abrangendo 1.177.858 pacientes com COVID-19 e FA, dos quais 893.772 (75,9%) estavam em anticoagulação crônica prévia para FA. Em pacientes com COVID-19, a anticoagulação crônica para FA reduziu significativamente a mortalidade por todas as causas (RR 0,75; IC 95% 0,57 a 0,99; p = 0,048; I2 = 89%) e a mortalidade relacionada à COVID-19 (RR 0,76; IC 95% 0,72 a 0,79; p < 0,001; I2 = 0%) quando comparada com a ausência de anticoagulação prévia. Em contrapartida, não houve diferença entre os grupos em relação à hospitalização (RR 1,08; IC 95% 0,82 a 1,41; p = 0,587; I2 = 95%) ou internação em UTI (RR 0,86; IC 95% 0,68 a 1,09; p = 0,216; I2 = 69%). Conclusões: Nesta metanálise, a anticoagulação crônica para pacientes com FA que contraíram COVID-19 foi associada a taxas significativamente mais baixas de mortalidade por todas as causas e mortalidade relacionada à COVID-19 em comparação com a ausência de anticoagulação anterior.

Abstract The canned Amazon River prawn with sauce (tucupi and jambu) was thermally prepared (121 ºC) at three different times (T1: 15 T2: 20 and T3: 25 minutes) in glass bottles. The product obtained 20.86% crude protein, with good acceptance by consumers (global acceptance >7) measured through centesimal and sensory analysis of the hedonic scale. Increased exposure caused obvious changes in the sensorial characteristics of the product, which were not evidenced by consumers in the sensorial analysis, and for this reason, texture profile analysis (TPA) and color (CIELAB) were carried out, in addition to analyses of concentration of Total Volatile Basic Nitrogen (TVB-N), hydrogen potential (pH) and microbiological performed during 12 months, in addition to yield and weight loss by cooking. The sensory analysis did not show a significant difference between the treatments, however, the yield reduced with the application of heat, with the best yield being in treatment T1 (58.76 ± 0.49 a). The centesimal analysis showed excellent values of protein content of 20.86% and lipid content of 0.33%. The treatments followed the variation in color and texture according to the application of heat, mainly concerning the increase in the b* value (10.84 ± 0.70 to 13.50±0.24) and reduction in cohesiveness (0.56 ± 0.05 to 0.50 ± 0.04), gumminess (368.81± 109.23 to 262.09 ± 63.78 g) and chewiness (999.30 ± 356.92 to 633.71 ± 221.56 g). Despite this, the product proved to be safe during the analyzed period without the development of the remaining bacteria, even with an increase in pH (4.2 to 5.9) and TVB-N (20.22 to 28.46 mg/100 g), despite this, there was no development of the bacteria analyzed, proving to be a product suitable for industrial implementation. tucupi jambu 121 (12 ºC T (T1 1 T2 2 T3 minutes bottles 2086 86 20.86 global >7 7 scale reason TPA (TPA CIELAB (CIELAB out TVBN, TVBN TVB N , (TVB-N) (pH months cooking however heat 58.76 5876 58 76 (58.7 049 0 49 0.4 a. . a) 033 33 0.33% b 10.84 1084 10 84 (10.8 070 70 0.7 13.50±0.24 1350024 13 50 24 0.56 056 56 (0.5 005 05 0.0 050 0.5 0.04, 004 0.04 04 0.04) 368.81± 36881 368 81 (368.81 10923 109 23 109.2 26209 262 09 262.0 6378 63 78 63.7 g 999.30 99930 999 30 (999.3 35692 356 92 356.9 63371 633 71 633.7 22156 221 221.5 g. 4.2 42 4 (4. 5.9 59 5 9 20.22 2022 22 (20.2 2846 28 46 28.4 mg100 mg 100 mg/10 g, implementation (1 (T 208 8 20.8 > (TVB-N 58.7 587 (58. 0. 03 3 0.33 10.8 108 (10. 07 13.50±0.2 135002 (0. 00 368.81 3688 36 (368.8 1092 109. 2620 26 262. 637 6 63. 999.3 9993 99 (999. 3569 35 356. 6337 633. 2215 221. 4.

Abstract The thorough redox alteration of a lava flow is an undescribed feature in intraplate basaltic provinces. The Early Cretaceous (134.5 Ma) Paraná Province displays that alteration in the major Muralha Flow. This oxidized and reduced flow from the southern part of the province was studied with satellite images, field surveying, petrography, and published whole rock geochemistry. The 100 x 100 km flow from the Cuesta de Haedo presents two hydrothermal tiers – lower Tier 1 is gray to white, upper Tier 2 is red. Iron oxyhydroxides characterize Tier 2. Tier 1 contains clay minerals, zeolites, pyrite and calcite, and agate (possibly amethyst) geodes. In a first event, the upper Tier 2 was oxidized by hot water from the underlying Guarani Paleoaquifer. The high water/rock ratio decreased due to porosity clogging by precipitation of secondary minerals, and the fluid became reducing. Lowering of Eh and pH was caused by reaction of water with reducing particles (calcite, organic molecules) present in the paleoerg sandstones and with fresh rock surfaces. A lower Tier 1 was then formed during slow, hot water percolation. Reduction was interrupted below 30 °C (calcite formation). Large scale, similar alteration occurred in all studied oceanic ridges and only rarely in continental environments. provinces 134.5 1345 134 5 (134.

Abstract To evaluate the polymerization shrinkage stress and cuspal strain (CS) generated in an artificial (typodont) and in a natural tooth using different resin composites. Twenty artificial and 20 extracted natural molars were selected. Each tooth was prepared with a 4x4 mm MOD cavity. The natural and typodont teeth were divided into four experimental groups (n=10), according to the resin composite used: Filtek Z100 (3M Oral Care) and Beautifil II LS (Shofu Dental). The cavities were filled using two horizontal increments and the CS (µS) was measured by the strain gauge method. Samples were sectioned into stick-shaped specimens and the bond strength (BS) (MPa) was evaluated using a microtensile BS test. Shrinkage stress and CS were analyzed using 3D finite element analysis. No difference was found between the type of teeth for the CS as shown by the pooled averages: Natural tooth: 541.2 A; Typodont model: 591.4 A. Filtek Z100 CS values were higher than those obtained for Beautifil II LS, regardless of the type of teeth. No statistical difference was found for the BS data. Adhesive failures were more prevalent (79.9%). High shrinkage stress values were observed for Filtek Z100 resin, regardless of tooth type. The CS of typodont teeth showed a shrinkage stress effect, generated during restoration, equivalent to that of natural teeth.

Abstract In this study, our objective was to conduct a comprehensive phytochemical analysis, determine toxicity levels, and assess the antioxidant and antimicrobial properties of extracts derived from the leaves of Dipteryx alata Vogel, a native species of the Brazilian cerrado flora. Three distinct extracts were prepared utilizing assisted ultrasound and the Soxhlet apparatus, namely, Ultrasound Crude Extract (UCE), Soxhlet Crude Extract (SCE), and the Soxhlet Ethanol Extract (SEE). The phytochemical analysis revealed the presence of flavonoids, tannins, phytosterols, and saponins in all extracts. Additionally, alkaloids were specifically identified in the SCE and SEE extracts. In the analysis using LC-DAD, the compounds gallic acid, rutin, quercetin, luteolin and kampefrol were determined in higher concentrations in the SCE, followed by the SEE and UCE, respectively. The GC-MS analysis revealed the presence of campesterol, stigmasterol and β-sitosterol in all extracts, with UCE and SCE showing a higher concentration of β-sitosterol. SCE showed the highest concentration of all identified compounds. In the analysis of antioxidant activity by DPPH• and ABTS•+, SEE showed greater efficiency (IC50 = 2.98 ± 2.92 and 6.57 ± 0.89 μg/mL, respectively). In the toxicity test with Allium cepa, all extracts stimulated root growth at 50 g/mL; UCE and SEE stimulated root growth at 250 g/mL; and SEE inhibited root growth at 750 g/mL. In the Artemia salina toxicity, all extracts were non-toxic. Antibacterial activity was identified in the microorganisms S. aureus and S. mutans; however, the extracts did not show antifungal action against the strain of C. albicans. The extracts of D. alata have therapeutic potential for applicability in dentistry. study levels Vogel flora apparatus namely , (UCE) (SCE) SEE. .

Abstract Tea is identified as the second most consumed drink in the world, and its frequent intake is related to several benefits to human health, considering its antimutagenic, anticarcinogenic, antimicrobial, anti-inflammatory, antihistamine, diuretic, calming, and above all, antioxidant effects. These effects are often associated with the action of the phenolic compounds contained in these infusions. In Brazil, among the most consumed infusions are the teas of chamomile (Matricaria chamomilla L.), lemongrass (Cymbopogon citratus (D.C.) Stapf), lemon balm (Melissa officinalis L.), anise (Pimpinella anisum L.), yerba mate (Ilex paraguariensis A. St.-Hil), peppermint (Mentha piperita L.), and green/black tea (Camellia sinensis L.). Therefore, said popularity is the reason why the mentioned species were chosen to be evaluated on inflammatory enzymes. The activity of phospholipases A2 was reduced by more than 25% after treatment with black tea and yerba mate. The most significant inhibition of protease activity was observed after incubation with black tea (40.74%), green tea (31.48%) and yerba mate (25.93%). Infusions of black and green tea reduced hemolysis in semisolid and liquid media, and for the latter, reductions of up to 50% of hemolytic activity were observed, indicating an anti-inflammatory potential of the samples. Plasma incubations with green tea, black tea and lemon balm and subsequent addition of venom (1:10 ratio; tea:PBS, v:v) prolonged the coagulation time of citrated plasma by approximately twice compared to the positive control. All controls with pure tea had a thrombolytic character, in higher proportions than the venom control, especially chamomile (273.55% dissolution). Phenolic compounds derived from phenolic acids, flavonoids, and tannins are identified as the main agents that promote the biological effects observed in this study. This is mainly due to their anti-catalytic properties exerted on inflammatory enzymes and as chelating agents of enzymatic co-factors. The evaluated teas showed potential for nutraceutical use, thus pointing to the possibility of use as an adjuvant in the treatment of diseases linked to hemostasis. world health antimutagenic anticarcinogenic antimicrobial antiinflammatory, antiinflammatory anti inflammatory, antihistamine diuretic calming all Brazil Matricaria L., L L. , L.)

Industrial waste products are of biotechnological interest due to their abundance and can be utilized as protein sources for the production of bioactive peptides through hydrolysis. The utilization of yeast residues from the brewing industry has been demonstrated to be a viable method for obtaining protein hydrolysates. The degree of hydrolysis and soluble total protein of the hydrolysates were evaluated for optimization purposes to achieve a product with a high proportion of soluble organic nitrogen, increased levels of bioactive peptides and amino acids. Both alkaline and enzymatic hydrolysis processes were tested. The hydrolyses were carried out with the aim of large-scale implementation. The treatments were effective in liberating intracellular content and producing biologically functional hydrolysates, with degree of hydrolysis values ranging from 28 to 63% and total protein from 2.95 to 8.28% at the optimum points confrmed by statistical analysis (analysis of variance (ANOVA)). The hydrolysate produced with Alcalase® exhibited the highest peptide intensity, while the hydrolysate produced with Flavourzyme® showed the highest concentration of free amino acids. The peptides were identifed by mass spectrometry and were found to have biological activities according to the Biopep database. This study presents a quick and economically feasible approach for the implementation of a pilot project for the reuse of this waste. nitrogen acids tested largescale large scale 2 63 295 95 2.9 828 8 8.28 ANOVA.

Abstract This study compares the physicochemical characteristics of breast meat (Pectoralis major) from conventional chicken and free-range chicken production systems. Analyses of pH, instrumental color measurement, weight loss from cooking (WLC), and water retention capacity (WRC) were carried out. Average pH values were slightly higher for conventional chicken samples. WLC did not show a significant difference between conventional and free-range chicken samples. The WRC was better and higher for the free-range chicken samples than the conventional ones. The mean values for luminosity (L*) were within the normal range, with slightly higher values for conventional chicken. In chromatids a* and b*, there was a tendency towards a more reddish color for free-range chicken samples. The differences found for types of production can be explained mainly by the difference in age at slaughter, the degree of physical activity, animal feeding, among other characteristics that differentiate an animal raised by the extensive system from the intensive system.

Resumo Este estudo compara as características físico-químicas da carne de peito (Pectoralis major) de frangos de granja e caipiras. Foram realizadas análises de pH, medição de cor instrumental, perda de peso por cocção (PPC) e capacidade de retenção de água (CRA). Os valores médios de pH foram ligeiramente maiores para as amostras de frango de granja. PPC não apresentou diferença significativa entre as amostras de frango de granja e frango caipira. O CRA foi melhor e maior para as amostras de frango caipira do que para as amostras de frango. Os valores médios de luminosidade (L*) ficaram dentro da normalidade, com valores ligeiramente superiores para frango de granja. Nas cromátides a* e b*, houve uma tendência de coloração mais avermelhada para as amostras de frango caipira. As diferenças encontradas para os tipos de produção podem ser explicadas principalmente pela diferença de idade ao abate, grau de atividade física, alimentação do animal, entre outras características que diferenciam um animal criado pelo sistema extensivo em relação ao sistema intensivo. físicoquímicas físico químicas Pectoralis major caipiras instrumental (PPC CRA. .
