RESUMO: O melão de polpa alaranjada honeydew apresenta elevado potencial nutricional e econômico, sendo amplamente apreciado como fruta doce e refrescante. Portanto, avaliar amostras comerciais de produtos tão relevantes para o mercado de frutas frescas é de grande importância. O objetivo deste estudo foi investigar a capacidade antioxidante, os parâmetros de qualidade e a composição química de melões do mercado brasileiro. Os valores de pH e ºBrix determinados para as amostras de melão foram 6,5 ± 0,30 e 9,2 ± 0,80 g/100 g (peso fresco), respectivamente, o que está de acordo com os resultados esperados para melões de alta qualidade. A análise cromatográfica revelou a sacarose (49% do açúcar total) como principal açúcar, seguida pela frutose (30%) e glicose (21%). Os carotenóides, que estão diretamente ligados à cor laranja característica, apresentaram teor total de 270,59 µg/g (peso seco). Além disso, o maior valor de b* comparado ao valor de a* indica a maior contribuição da cor amarela. Quanto ao potencial antioxidante, além de apresentar capacidade antioxidante para ambos os métodos aplicados, DPPH e FRAP, níveis variando de 16,40 ± 0,21 µmol equivalente de ácido ascórbico/g a 56,98 ± 0,80 µmol equivalente de Trolox/g (peso seco) foram encontrados nos extratos de melão. Ademais, os resultados foram maiores em termos de FRAP do que em DPPH. Desta forma, os resultados destacam os melões avaliados como fontes valiosas de compostos bioativos, como carotenóides e fenólicos, que contribuem para suas propriedades antioxidantes. Além disso, análises de cor, pH e teor de sólidos solúveis totais também refletem os atributos de qualidade.

ABSTRACT: Orange-fleshed non-netted honeydew melon has high nutritional and economic potential, being widely appreciated as a refreshing sweet fruit. Therefore, evaluating commercial samples of such relevant products for the fresh fruit market is of great importance. This study investigated the antioxidant capacity, quality parameters, and chemical composition of honeydew melons from the Brazilian market. The values of pH and °Brix determined for melon samples were 6.5 ± 0.30 and 9.2 ± 0.80 g/100 g (fresh weight), respectively, which agree with the results expected for high-quality melons. The chromatography analysis revealed sucrose (49% of total sugar) as the main sugar, followed by fructose (30%) and glucose (21%). Carotenoids, which are directly linked to the characteristic orange color, showed a total level of 270.59 µg/g (dry weight). Additionally, the higher b* value compared to a* value indicates the highest yellow contribution. Regarding the antioxidant assays, in addition to presenting antioxidant capacity for both methods applied, DPPH and FRAP, levels ranging from 16.40 ± 0.21 µmol ascorbic acid equivalent/g to 56.98 ± 0.80 µmol Trolox equivalent/g (dry weight) were reported in melon extracts. Moreover, the results were higher in terms of FRAP than DPPH. Therefore, the results underscore the evaluated honeydew melons as valuable sources of bioactive compounds, such as carotenoids and phenolics, which contribute to their antioxidant properties. Besides, analyses of color, pH, and total soluble solids content also reflect the quality attributes.

RESUMO A cultura do sorgo é considerada uma das mais importantes do mundo devido a sua versatilidade de utilização. No entanto, o estresse hídrico pode ser considerado uma ameaça significativa para sua produtividade. A busca por produtos mitigadores do estresse hídrico é uma área de pesquisa crucial na agricultura e na gestão de recursos hídricos. Assim, o objetivo deste trabalho foi avaliar a viabilidade do uso do ácido salicílico como atenuante de estresse hídrico na cultura do sorgo. O experimento foi conduzido em ambiente telado, em delineamento em blocos ao acaso com esquema fatorial 4 × 2, com quatro repetições. Foram avaliados quatro níveis hídricos (40, 60, 80 e 100% da evapotranspiração) e duas concentrações de ácido salicílico (0 e 2,76 g L-1). Foram analisados a altura das plantas, diâmetro do caule, número de folhas, trocas gasosas, pigmentos fotossintéticos e fluorescência da clorofila a. A aplicação de lâminas de irrigação deficitárias reduziu a altura da planta, diâmetro do colmo, número de folhas e clorofila total no sorgo. No entanto, quando essas lâminas foram associadas ao ácido salicílico, foi observado que houve atenuação dos danos, especialmente em relação a clorofila a e b. Além disso, o ácido salicílico quando aplicado isoladamente, contribuiu para redução da temperatura da folha e aumento da eficiência de uso da água. Assim, o ácido salicílico pode ser usado para mitigar os efeitos do estresse salino em plantas de sorgo. utilização entanto produtividade Assim telado 2 repetições 40, 40 (40 60 8 100 evapotranspiração 0 ( 276 76 2,7 L1.

ABSTRACT The sorghum crop is considered one of the most important worldwide due to its versatility. However, water stress can be considered a significant threat to its yield. The search for products that mitigate water stress is a crucial area of research in agriculture and water resources management. Thus, the objective in this study was to evaluate the feasibility of using salicylic acid as a water stress attenuator in sorghum. The experiment was conducted in a screened environment in a randomized block design with a 4 × 2 factorial scheme, with four replicates. Four levels of water (40, 60, 80, and 100% of evapotranspiration) and two concentrations of salicylic acid (0 and 2.76 g L-1) were evaluated. Plant height, stem diameter, number of leaves, gas exchange, photosynthetic pigments, and chlorophyll a fluorescence were analyzed. Application of deficit irrigation depths reduced plant height, stem diameter, number of leaves, and total chlorophyll in sorghum. However, when these depths were associated with salicylic acid, it was observed that the damage was attenuated, especially in chlorophyll a and b. Furthermore, salicylic acid reduced leaf temperature and increased water use efficiency when applied alone. Thus, salicylic acid can be used to mitigate the effects of salt stress on sorghum plants. versatility However yield management Thus scheme replicates 40, 40 (40 60 80 100 evapotranspiration 0 ( 276 76 2.7 L1 L 1 L-1 evaluated height diameter leaves exchange pigments analyzed attenuated b Furthermore alone plants (4 6 8 10 27 7 2.

ABSTRACT Safflower is a crop with seeds containing high amounts of oleic and linoleic acids, which have applications in cosmetics, food, feed, and pharmaceutical industries. Safflower seeds are generally reported to undergo after-ripening and to have physiological dormancy. This study comprehensively analyzed the physical changes and the induction of dormancy and germinability in developing seeds to determine whether the safflower population is adequately developed during seed dispersal. From the 80th day after flowering (DAF), seeds were collected separately from plants on a weekly basis until 131 DAF, resulting in seven sampling dates. The changes in length, diameter, thickness, water content, and fresh and dry weight during seed development were measured. Simultaneously, the effects of dark and light, temperature, and gibberellic acid (GA3) (0, 50, and 100 µM) on seed germination, dormancy and germination characteristics of safflower seeds were investigated. The seeds ceased to increase in length, width and thickness, reaching a mature appearance at 131 DAF, with a dry mass per seed of 0.0443 g. The water content decreased between 117 and 124 DAF, indicating an obvious process of desiccation during the final stage of seed maturation. Germination capacity is acquired at 117 DAF, as evidenced by an increase in germination and a reduction in dormant seeds, particularly at low temperatures (10°C) and with GA3 supplementation. At 131 DAF, seeds exhibited 7.9 % water content, and there was an increase in seed germination and a decrease in seed dormancy status, regardless of GA3 supplementation and temperature. acids cosmetics food feed industries afterripening ripening dispersal th DAF , (DAF) 13 dates length diameter thickness measured Simultaneously light temperature GA (GA3 0, 0 (0 50 10 µM investigated 00443 0443 0.044 g 11 12 maturation 10°C 10C C (10°C 79 7 9 7. status (DAF 1 (GA ( 5 0044 044 0.04 004 04 0.0 00 0.

RESUMO Este estudo analisou um biomaterial substituto ósseo recentemente desenvolvido feito de óxido de quitosana- xantana-hidroxiapatita-grafeno (CXHAG). As partículas CXHAG observaram caracterização estrutural e morfológica in vitro. Foi testado in vivo, com ou sem meio condicionado osteogênico de células-tronco mesenquimais. Objetivo O objetivo deste estudo foi determinar se o novo biomaterial CXHAG, suplementado com meio condicionado de células-tronco mesenquimais, poderia ser útil para a regeneração óssea. Materiais e Método Para o estudo in vitro, as células foram incubadas com 20mg de grânulos de CXHAG por 24 horas e foi realizado ensaio de MTT para verificar a citotoxicidade. Para o estudo in vivo, foram criados defeitos ósseos de tamanho crítico na calvária em vinte e cinco ratos. Um animal teve o defeito não preenchido (Grupo Controle – GC) e foi eutanasiado após 42 dias. Doze ratos receberam as partículas CXHAG (Grupo 1 – G1) e os outros doze receberam as partículas CXHAG suplementadas com o meio condicionado (Grupo 2 – G2). Todos os enxertos G1/G2 foram cobertos com membrana CXHAG. Os animais do G1/G2 foram eutanasiados após 14 dias (T1) ou 42 dias (T2). Os espécimes foram processados e avaliados histologicamente. Resultados A análise SEM das partículas CXHAG mostrou grânulos de 300-400μm, com superfície áspera e irregular. Eles não foram citotóxicos para células-tronco da polpa dentária in vitro. As amostras CG mostraram tecido conjuntivo imaturo frouxo e nenhuma formação óssea no centro do defeito. G1 e G2 apresentaram partículas remanescentes de biomateriais em ambos os momentos, mas apenas G2 apresentou formação óssea no centro do defeito. Conclusões O meio condicionado teve repercussões positivas na regeneração óssea em defeitos críticos de calvária de ratos quando associado ao novo biomaterial substituto ósseo.

ABSTRACT This study analyzed a recently developed bone substitute biomaterial made of chitosan-xanthanhydroxyapatite- graphene oxide (CXHAG). The CXHAG particles underwent in vitro structural and morphological characterization, and in vivo testing with or without osteogenic conditioned medium from mesenchymal stem cells. Aim The aim of this study was to determine whether the CXHAG novel biomaterial, supplemented with conditioned medium from mesenchymal stem cells, could be useful for bone regeneration. Materials and Method For the in vitro study, cells were incubated with 20mg of CXHAG granules for 24 hours and a MTT assay was performed to tests for cytotoxicity. For the in vivo study, critical size calvarial bone defects were created in twenty-five rats. One animal had the defect unfilled (Control Group–CG) and was euthanized after 42 days. Twelve rats received the CXHAG particles (Group 1–G1) and the other twelve received the CXHAG particles supplemented with the conditioned medium (Group 2–G2). All G1/G2 grafts were covered with a CXHAG membrane. G1/G2 animals were euthanized after 14 days (T1) or 42 days (T2). The specimens were processed and histologically evaluated. Results SEM analysis of the CXHAG particles showed granules of 300-400μm, with a rough irregular surface. They were not cytotoxic to dental pulp stem cells in vitro. The CG specimen showed loose immature connective tissue and no bone formation at the center of the defect. G1 and G2 presented remnant biomaterial particles at both time points, but only G2 had bone formation at the center of the defect. Conclusions The conditioned medium had a positive effect on bone regeneration in rat calvarial critical size defects when associated with the novel bone substitute biomaterial.

ABSTRACT Tamarind (Tamarindus indica L.) is a species with promising potential for commercial production; therefore, studies involving practices of conducting culture in the initial stage are essential. The present study aimed to evaluate different shading levels and substrate compositions in the seedling production of tamarind. The experimental design was completely randomized in a 4×4 factorial scheme, four levels of shading (0%, 18%, 30%, and 50%) and four substrates (pine bark-based substrate pure and mixed with 50% vermiculite, and sphagnum peat-based substrate pure and mixed with 50% vermiculite), with four replicates of four seedlings. Growth and biometric relationships were evaluated at 40 and 98 d after transplantation (DAT). The results reported that seedlings formed on the sphagnum peat-based substrate on pure or associated with vermiculite at 98 DAT had a height greater than 35 cm and a total 8.5 g DM. In contrast, seedlings produced in pine bark-based substrate did not reach 20 cm in height and had less than 3 g total DM. The condition of 30% and 50% shading promoted greater growth in height, reaching an average height greater than 40 cm, while in the full sun environment, seedlings showed an average of less than 35 cm; however, for the other variables, full sun environment did not differ from 30% shading, producing good quality seedlings. Thus, the cultivation of seedlings in an environment with 0% or 30% shading, associated with the sphagnum peat-based substrate pure or mixed with 50% vermiculite promoted the production of tamarind seedlings with vigorous growth. In the best environments, the best substrates increased, on average, 41.3% number of leaves, 80.5% shoot dry mass, 56.8% root dry mass, and 71.0% total dry mass. In the best substrates, the best environments increased, on average, 18.0% number of leaves, 20.7% shoot dry mass, 8.7% root dry mass, and 14.3% total dry mass.

RESUMO: Objetivou-se estimar o crescimento corporal, carcaça, cortes nobres, vísceras comestíveis e penas de codornas japonesas criadas em dois ambientes térmicos e alimentadas com três planos nutricionais de um a 39 dias. Foram utilizadas 576 pintainhas (Coturnix japônica), fêmeas, com um dia de idade, com peso médio inicial 7,51 ± 0,75g/ave, distribuídas em delineamento inteiramente casualizado em esquema fatorial 3 × 2 (três planos nutricionais x duas temperaturas), alojadas em duas câmaras climáticas de 25º e 35 ºC, com 12 repetições e oito aves por unidade experimental. Os planos nutricionais foram: plano nutricional um (PN1) - uma dieta de 1-21 dias e uma dieta de 22-39 dias; plano nutricional dois (PN2) - uma dieta de 1-14 dias e uma dieta de 15-39 dias; e plano nutricional três (PN3) - dieta única de 1-39 dias. Foram avaliadas as curvas e taxas de crescimento corporal, carcaça, cortes nobres, penas e vísceras comestíveis, através do modelo matemático de Gompertz. Codornas alimentadas com PN3 apresentaram maiores curvas e taxas de crescimento corporal, de carcaça, coxa + sobrecoxa e penas. Houve efeito para taxa de maturidade, sendo inferior para codornas alojadas em 35 ºC. Nas aves mantidas em 25 ºC, observou-se maior taxa de crescimento e peso de peito nas codornas alimentadas com PN3. O plano nutricional composto por uma única dieta ofertada durante o período de um a 39 dias, formulado com base nas recomendações das tabelas para codornas japonesas e europeias, é o mais indicado para estimar curvas de crescimento no modelo de Gompertz de codornas japonesas alojadas em 25 ºC ou 35 ºC.

ABSTRACT: This study estimated the growth of body, carcass, primal cuts, edible offal, and feathers of Japanese quail reared in two thermal environments, receiving three nutritional plans, from one to 39 days of age. A total of 576 one-day-old female chicks (Coturnix japonica) with an average initial weight of 7.51±0.75g/bird were evaluated in a completely randomized design with a 3 × 2 factorial arrangement (three nutritional plans × two temperatures). The animals were housed in two climatic chambers, at 25 ºC and 35 ºC, using 12 replications with eight birds per experimental unit. Nutritional plans (NP) were as follows: NP1: one diet from 1-21days and another from 22-39 days; NP2: one diet from 1-14 days and another from 15-39 days; and NP3: a single diet from 1-39 days. The growth curves and growth rates of body, carcass, primal cuts, feathers, and edible offal were evaluated using the Gompertz mathematical model. Quail fed NP3 showed higher growth curves and rates for body, carcass, drumstick +thigh, and feather. There was an effect on maturity rate, which was lowest in quail housed at 35 ºC. Among the animals kept at 25 ºC, the group fed NP3 exhibited the highest growth rate and breast weight. The nutritional plan consisting of a single diet offered from 1 to 39 days, formulated based on the tables for Japanese and European quail, is the most suitable for estimating the growth curves (Gompertz model) of Japanese quail housed at 25 ºC or 35 ºC.

ABSTRACT Background: The macauba (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) is a palm tree native to tropical regions and occurs in much of the Brazilian territory. Current studies are focused on the extraction and exploitation of vegetable oil from this fruit. However, there are few studies on the residue, the endocarp, which represents approximately 25% of the total mass of the fruit. Studies that search for solutions for using residue, thus adding value, and generating environmentally friendly products, are of fundamental importance. Thus, this research aimed to evaluate the physical and mechanical properties of reconstituted wood panels produced with different proportions of macauba endocarp particles to replace pine wood particles, in addition to characterize the physical and chemical properties of macauba endocarp. The chemical characterization tests were performed according to applicable standards. The basic density was determined according to the NBR 11941 standard. Thermogravimetric analysis (TGA), X-ray diffractometry (XRD) and Fourier transform infrared spectroscopy (FTIR) were also performed. The particleboards panels were produced with a nominal density of 0.70g/cm³ and dimensions of 25x25x1.5cm. Five different treatments were evaluated with variations in the proportion of macauba endocarp particles in the core of the panel. For particle agglutination, phenol-formaldehyde adhesive was used at a proportion of 9% for the core and 12% for the faces, based on the dry mass of each panel. Scanning electron microscopy (SEM) was used to analyze the panel surfaces. Results: The endocarp of Acrocomia aculeata has low extractive content, high lignin content and high densification, 1.23g/cm³, when compared to Pinus oocarpa wood, 0.43g/cm³. All panels were classified as low density according to CS 236-66 and had an average apparent density between treatments of 0.586g/cm³. A greater dimensional stability and a decrease in the static bending properties of the panels was observed as the proportion of macauba endocarp particles increased. The internal bonding of the panels showed a positive result with the increase in the use of particles of the residue. Conclusion: The panels produced have potential for use for non-structural purposes. Background Jacq. Jacq (Jacq. Lodd Mart.

The interactive profile between four 1,4-naphthoquinone derivatives (1-4) and human serum albumin (HSA) was studied by spectroscopic techniques and in silico calculations. The bimolecular quenching rate constant (kq ca. 1012 L mol-1 s-1) and the time-resolved fluorescence decays indicated a static fluorescence quenching mechanism. Thus, there is a spontaneous ground-state association, and based on both Stern-Volmer, modified Stern-Volmer, and van’t Hoff approaches, the association is moderate mainly driven by hydrophobic forces. The circular dichroism (CD) analysis indicated that until the proportion albumin:compound of 1:8 there is a weak perturbation on the structural content of albumin, while molecular docking results suggested subdomain IIA (site I), a positive electrostatic pocket, as the main binding site. Overall, even though the hydrogen atom replacement by methyl, fluorine, or chlorine atoms in the para position of the aromatic ring in the benzo[g]chromene-5,10-dione moiety changes the lipophilicity, it does not change the binding profile to HSA. 1,4naphthoquinone 14naphthoquinone naphthoquinone 1,4 1 4 14 (1-4 HSA (HSA calculations kq ca 101 mol1 mol mol- s1 s s-1 timeresolved time resolved mechanism Thus groundstate ground state SternVolmer, SternVolmer Stern Volmer, Volmer Stern-Volmer vant van t approaches forces CD (CD albumincompound compound 18 8 1: site I, I , I) pocket Overall methyl fluorine benzogchromene5,10dione benzogchromene510dione benzogchromenedione benzo g chromene 5,10 dione 5 10 lipophilicity 4naphthoquinone 1, (1- s- benzogchromene5 10dione benzogchromene 510 5,1 (1 51 5, (

ABSTRACT Biological soil crusts (BSC) are commonly found in soils in the drylands regions, which can influence stabilization, water retention, nutrient cycling (particularly carbon (C) and nitrogen (N) dynamics), and several ecological processes. However, the composition of BSC in Brazilian soils undergoing the desertification process remains poorly understood. This study aimed to characterize the bacterial community in BSC formed in a Brazilian semiarid region under the desertification process. Thus, a highly desertified region was selected from which 34 BSC samples were collected. The total DNA of the BSC was extracted from 0.5 g samples, and the bacterial community was sequenced by a Next Generation Sequencing (NGS) platform (Miseq – Illumina®) using universal primers (515F and 806R). Bioinformatic analysis was carried out in QIIME (v.1.9), and the Operational Taxonomic Units (OTU) table was constructed following the Sumaclust methodology. The pH of BSC, C, N, and phosphorus contents was analyzed. Our study identified a diverse bacterial community in the BSCs. Cyanobacteria, Chloroflexi, and Proteobacteria phyla presented the greatest relative abundance (%) across the samples. Cyanobacteria were dominated by the orders Nostocales and Leptolyngbyales. The prediction of the putative functions found that mostf OTU were related to phototrophy, photosynthetic cyanobacteria, and photoautotrophy. The study found correlations between bacterial phyla and BSC properties, with Cyanobacteria positively related to C. Chloroflexi, Armatimonadetes, and WPS-2 were negatively correlated with C and N contents. These results suggest the critical roles bacteria communities play in BSCs from the Caatinga biome and highlight the potential impact of environmental factors on their diversity and functions.

Aim This study aimed to investigate the occurrence of enamelin gene (ENAM) single nucleotide polymorphisms (SNP) and ENAM polymorphism association with dental anomalies (DA) in individuals with unilateral or bilateral cleft lip and palate (CLP). Methods Saliva samples were collected from 147 individuals aged between 6 and 15 years-old, both genders, and divided into 4 groups: Group 1 (G1) - CLP and DA; Group 2 (G2) - CLP without DA; Group 3 (G3) - without CLP with DA; Group 4 (G4) - without CLP and DA. The genomic DNA was extracted from saliva samples and the following ENAM SNPs markers were genotyped: rs3796703, rs3796704, rs3796705, rs7671281, rs2609428, and rs35951442. Fisher exact and Pearson’s Chi-square tests statistically analyzed the results (α=5%). Results Individuals without CLP with DA (Group 3 - 19.2%) showed statistically higher prevalence of SNP rs2609428 heterozygotes (p=0.006) than individuals with CLP and DA (Group 1 - 0%). Individuals without CLP (10%) exhibited statistically higher prevalence of mutated heterozygotes/homozygous (p=0.028) than in individuals with CLP (1.3%). Conclusion SNP rs2609428 marker of ENAM gene may be associated with dental anomalies in individuals without cleft lip and palate. (ENAM (SNP (DA CLP. .

Foi empregado um delineamento em blocos casualizados com cinco tratamentos e cinco repetições. Um tratamento controle com coentro sem fertilizante foi incluído para comparação. A cultivar de coentro ('Verdão') foi avaliada quanto à qualidade nutricional (pH, sólidos solúveis [SS], acidez titulável [AT], relação SS/AT, açúcar solúvel total [SST], vitamina C [CV] e teor de pigmento [ clorofila 'a' e 'b', clorofila total e carotenóides]). A incorporação de 25,10 e 51,36 t ha-1 da mistura dos adubos verdes resultou em coentro com máxima eficiência de sabor (10,43 °Brix/% ácido málico) e teor de açúcares solúveis totais (3,71 °Brix). Maiores concentrações de vitamina C (69,19 mg 100 g-1), clorofila 'a' (0,69 mg g-1), clorofila 'b' (0,16 mg g-1), clorofila total (0,84 mg g-1) e carotenóides (0,19 mg g-1) foram alcançadas com aplicações de 48,71, 56,73, 53,52, 57,04 e 42,08 t ha-1 da mistura dos adubos verdes, respectivamente. jitirana (jitirana flordeseda, flordeseda flor seda , (flor-de-seda) 16, 16 (16 29 42 5 6 ha1 ha 1 ha- seco semiárida repetições comparação Verdão ('Verdão' pH, pH (pH SS, SS [SS] AT, AT [AT] SSAT SS/AT SST, SST [SST] CV [CV a 'a b, b carotenóides. . carotenóides]) 2510 25 10 25,1 5136 51 36 51,3 10,43 1043 43 (10,4 Brix °Brix/ málico 3,71 371 3 71 (3,7 °Brix. °Brix °Brix) 69,19 6919 69 19 (69,1 g1, g1 g 0,69 069 0 (0,6 'b 0,16 016 (0,1 0,84 084 84 (0,8 g-1 0,19 019 4871 48 48,71 5673 56 73 56,73 5352 53 52 53,52 5704 57 04 57,0 4208 08 42,0 respectivamente (flor-de-seda (1 2 4 ('Verdão [SS [AT [SST carotenóides] 251 25, 513 51, 10,4 104 (10, 3,7 37 7 (3, 69,1 691 (69, 0,6 06 (0, 0,1 01 0,8 8 g- 487 48,7 567 56,7 535 53,5 570 57, 420 ( 10, (10 3, (3 69, (69 0, (0 48, 56, 53, (6

ABSTRACT This study aimed to evaluate the effects of incorporating green manure, in equal proportions of Merremia aegyptia (hairy woodrose) and Calotropis procera (roostertree) biomass, at varying rates (16, 29, 42, 55, and 68 t ha-1 dry weight) on the quality of coriander shoots grown in a single season under semi-arid conditions. A randomized block design with five treatments and five replicates was employed. A control treatment with coriander without fertilizer was included for comparison. The coriander cultivar ('Verdão') was evaluated for nutritional quality (pH, soluble solids [SS], titratable acidity [TA], SS/TA ratio, total soluble sugar [TSS], vitamin C [VC], and pigment content [chlorophyll 'a' and 'b', total chlorophyll, and carotenoids]). The incorporation of 25.10 and 51.36 t ha-1 of the green manure mixture resulted in coriander with the maximum flavor efficiency (10.43 °Brix/% malic acid) and total soluble sugar content (3.71 °Brix). Higher concentrations of vitamin C (69.19 mg 100 g-1), chlorophyll 'a' (0.69 mg g-1), chlorophyll 'b' (0.16 mg g-1), total chlorophyll (0.84 mg g-1), and carotenoids (0.19 mg g-1) were achieved with applications of 48.71, 56.73, 53.52, 57.04, and 42.08 t ha-1 of the green manure mixture, respectively. hairy woodrose roostertree (roostertree biomass 16, 16 (16 29 42 55 6 ha1 ha 1 ha- weight semiarid semi arid conditions employed comparison Verdão ('Verdão' pH, pH (pH SS, SS , [SS] TA, TA [TA] SSTA ratio TSS, TSS [TSS] VC, VC [VC] 'a b, b carotenoids. . carotenoids]) 2510 25 10 25.1 5136 51 36 51.3 10.43 1043 43 (10.4 Brix °Brix/ acid 3.71 371 3 71 (3.7 °Brix. °Brix °Brix) 69.19 6919 69 19 (69.1 g1, g1 g 0.69 069 0 (0.6 'b 0.16 016 (0.1 0.84 084 84 (0.8 0.19 019 g-1 4871 48 48.71 5673 56 73 56.73 5352 53 52 53.52 5704 57 04 57.04 4208 08 42.0 respectively (1 2 4 5 ('Verdão [SS [TA [TSS [VC carotenoids] 251 25. 513 51. 10.4 104 (10. 3.7 37 7 (3. 69.1 691 (69. 0.6 06 (0. 0.1 01 0.8 8 g- 487 48.7 567 56.7 535 53.5 570 57.0 420 42.

ABSTRACT Purpose: This study aimed to evaluate the effects of ozone therapy applied topically and/or by bagging on the healing of clean wounds induced in rat’s skin. Methods: One hundred and twenty male rats of about 16 weeks old was divided into five groups: G1) saline solution (0.9%); G2) sunflower oil; G3) ozonated sunflower oil; G4) ozone bagging; G5) association of ozonated sunflower oil and ozone bagging. The wounds were evaluated through macroscopic, morphometric, histopathologic, and tensile strength analyses. Results: Analysis among groups showed a lower percentage of wound contraction in G1 compared to G4 only in M7D. The tensile strength of the wounds showed differences among groups in the seventh (M7D) and the 14th (M14D) postoperative day, and among time points in G1 (M14D > M7D). The elongation of the wounds showed differences in G3 (M7D > M14D). Histological evaluation of the wounds showed significant change in bleeding, mixed to mononuclear infiltrate, congestion, and tissue disorganization for tissue organization between groups and time points. Conclusions: Ozone therapy applied topically and/or by bagging was not deleterious to the healing of clean wounds induced in rat’s skin, but ozone bagging showed the best contribution to the healing process.

ABSTRACT This study aimed to evaluate the productive and reproductive performance and the nutritional metabolic condition of ewes supplemented at different stages of gestation in a synchronized reproduction system. Fourty Santa Inês × Dorper crossbreed ewes, pregnant with an average age of ten months and two previous births, were distributed in a completely randomized design, with four treatments: mineral salt, supplementation started 20 days before the estrus synchronization (ES) protocol, supplementation from confirmation of pregnancy (60 days after ES), and supplementation in the final third of gestation (90 days after ES). The adoption of supplementation strategies during the beginning, middle, or end of pregnancy changed the intake and digestibility of dry matter (g/day), with a reduction of 10.53 and 9.14%, respectively, for the mineral salt treatment, in addition to organic matter, crude protein, neutral detergent fiber, acid detergent fiber, non-fibrous carbohydrates, ether extract, and total digestible nutrients, as well as protein, energy, and mineral profiles. There was no difference in the number of ovulations and reproductive and productive performance using supplementation alternatives. Supplementation strategies during the gestation stages influence the intake and digestibility of nutrients, as well as the animal metabolic profiles. However, it does not change reproductive and productive performance. system births design treatments 2 ES (ES protocol 60 (6 ES, , ES) 90 (9 ES. . beginning middle g/day, gday g/day g day (g/day) 1053 10 53 10.5 914 9 14 9.14% respectively treatment protein fiber nonfibrous non fibrous carbohydrates extract nutrients energy profiles alternatives However 6 ( (g/day 105 1 5 10. 91 9.14 9.1 9.

RESUMO Manejo de regra única é frequentemente adotado para várias espécies madeireiras de floresta tropical devido ao conhecimento limitado sobre o crescimento e a relação entre intensidade de exploração e tempo de recuperação de cada espécie. Este estudo fornece informações para subsidiar o manejo sustentável de Goupia glabra por meio da simulação da recuperação do estoque de madeira em um período de 35 anos usando dados de seis áreas na Amazônia brasileira. Períodos de monitoramento após o primeiro ciclo de colheita variaram de 16 a 29 anos e intensidades de exploração de 0.000 a 0.696 m² ha-1. A densidade arbórea de G. glabra variou de 0 a 22 árvores ha-1 e a dominância de 0,00 a 7,39 m² ha-¹. A frequência de diâmetros das árvores se distribuiu homogeneamente entre as classes diamétricas, com maior concentração na primeira classe (20-30 cm). Esses parâmetros geraram estimativas de taxa de recuperação de 12 a 85%, mostrando que 35 anos é insuficiente para árvores com DAP ≥ 20 cm recuperarem o estoque de árvores com DAP ≥ 50 cm colhidas no primeiro ciclo de colheita em todas as áreas. Prazos mínimos de recuperação de 48 a 83 anos foram estimados para garantir a recuperação do estoque de madeira nas áreas de estudo. Os resultados reforçam que as regras de manejo necessitam ser adaptadas à dinâmica populacional de cada espécie madeireira em cada local de exploração e sugerem a necessidade de mudar as exigências legais vigentes que definem o manejo florestal na Amazônia. 3 brasileira 1 2 0000 000 0.00 0696 696 0.69 m ha1. ha1 ha 1.

ABSTRACT Single-rule management is often adopted for various tropical forest timber species due to limited knowledge on species-specific growth and the relationship between logging intensity and recovery time. This study provides information to support sustainable management of Goupia glabra by simulating its wood stock recovery over a 35-year period following logging using data from six areas in the Brazilian Amazon. Monitoring periods after the first harvest cycle varyed from 16 to 29 years, and logging intensity from 0.000 to 0.696 m² ha-1. Tree density of G. glabra varied from 0 to 22 trees ha-1 and dominance from 0.00 to 7.39 m² ha-¹. Frequency of tree diameters was almost evenly distributed across diameter classes, slightly higher in the first (20-30 cm) class. These parameters generated estimations of recovery rate from 12 to 85%, showing that 35 years is insufficient for trees with DBH ≥ 20 cm in all study areas to grow and replace the stock of trees with DBH ≥ 50 cm harvested during the first cycle. Minimum recovery periods from 48 to 83 years were estimated to guarantee the recovery of the wood stock in the study areas. These findings reinforce the need to adapt management rules according to the population dynamics of each timber species and each logging area, and suggest the need for changes in the current legal requirements that define forest management in the Amazon.

ABSTRACT The rice husk was chemically treated with acetic acid and calcined at 600 °C, in an uncontrolled atmosphere to obtain the ash (RHA), and in an oxygen-limited atmosphere to produce the biochar (BC). The influence of the thermal treatment on the adsorbent properties for removing cationic (methylene blue) and anionic (methyl orange) dyes was investigated. Both materials showed amorphous structures rich in silica, with acicular morphology and a high roughness. High surface areas (157.2 and 215.5 m²g-1) and pH at the point of zero charge close to neutrality (6.73 and 6.58) for RHA and BC were found, respectively. The anionic dye was adsorbed only by BC due to its contribution to the π- π stacking interaction between the C=C bonds of the adsorbent and the benzene rings of the dye. In contrast, the cationic dye was adsorbed by electrostatic interaction between the Si-O-Si and Si-OH groups of the adsorbents, with the positive charge of the dye. All adsorption isotherms adjusted better to the SIPS model, suggesting adsorption in homogeneous and heterogeneous sites. The observed results suggest good adsorption capacities and the interactions between surface groups on the adsorbents and functional groups of the contaminants are the most important mechanism in the adsorption of dyes of different ionic natures on surfaces derived from rice husk. 60 C °C RHA, , (RHA) oxygenlimited oxygen limited BC. .
