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.

ABSTRACT Despite being subject to lower AIDS-related mortality rates and having a higher life expectancy, patients with HIV are more prone to develop non-AIDS events. A low CD4+/CD8+ ratio during antiretroviral therapy identifies people with heightened immune senescence and increased risk of mortality. In clinical practice, finding determinants of a low CD4+/CD8+ ratio may be useful for identifying patients who require close monitoring due to an increased risk of comorbidities and death. We performed a prospective study on the evolution of the CD4+/CD8+ ratio in 60 patients infected with HIV (80% males), who were subjected to two different antiretroviral regimens: early and deferred therapy. The initial CD4+/CD8+ ratio was ≤1 for 70% of the patients in both groups. Older age, CD4+ cell count at inclusion, Nadir CD8+T-cell count, and Initial CD4+/CD8+ ratio ≤ 1 were risk factors for lack of ratio recovery. In the multivariate analysis, a CD4+/CD8+ ratio > 1 at the start of the treatment was found to be a determinant factor in maintaining a CD4+/CD8+ ratio > 1. The nadir CD4+T-cell count was lower in the deferred therapy group (p=0.004), and the last CD4+/CD8+ ratio ≤1 was not associated with comorbidities. Ratio recovery was not associated with the duration of HIV infection, time without therapy, or absence of AIDS incidence. A greater improvement was observed in patients treated early (p=0.003). In contrast, the slope of increase was slower in patients who deferred treatment. In conclusion, the increase in the CD4+/CD8+ ratio occurred mostly for patients undergoing early strategy treatment and its extension did not seem to be related to previous HIV-related factors.

ABSTRACT Objective To estimate vaccination coverage and analyze sociodemographic factors associated with non-vaccination in children born in 2017 and 2018 in the state capitals of Northeast Brazil. Methods A household survey using cluster sampling was conducted from 2020-2022 to estimate vaccination coverage and hesitancy. Factors associated with non-vaccination were analyzed using logistic regression to calculate Odds Ratios (OR) and their Confidence Intervals (95%CI). Results Natal was the capital with the lowest vaccination coverage, below 75.0% for most immunizers. Teresina had rates equal to or greater than 90.0% for all vaccines. Among those interviewed, 99.1% (95%CI 98.9;99.3) believe that vaccines are important for health; 95.4% (95%CI 95.0;95.8) trust immunobiologicals and 79.6% (95%CI% 78.8;80.3) are not afraid of reactions. Belonging to the highest socioeconomic stratum (adjusted OR: 1.34 – 95%CI 1.20;1.50) was as a factor associated with non-vaccination. Conclusion Low coverage highlights the need for a better understanding of regional specificities and social inequalities.
RESUMO Objetivo Estimar a cobertura vacinal e analisar fatores sociodemográficos associados à não vacinação em crianças nascidas vivas em 2017 e 2018 nas capitais do Nordeste brasileiro. Métodos Realizou-se inquérito domiciliar com amostragem por conglomerados, entre 2020 e 2022, para estimar cobertura e hesitação vacinal. Fatores associados à não vacinação foram analisados usando-se regressão logística para calcular odds ratio (OR) e seus intervalos de confiança (IC95%). Resultados A capital com menores coberturas vacinais foi Natal, com < 75,0% para a maioria dos imunizantes; Teresina apresentou coberturas ≥ 90,0% em todos os imunizantes. Dos entrevistados, 99,1% (IC95% 98,9;99,3) acreditavam que vacinas são importantes para a saúde; 95,4% (IC95% 95,0;95,8) confiavam nos imunobiológicos distribuídos pelo governo; e 79,6% (IC95% 78,8;80,3) não tinham medo de reações adversas. Residir em estrato socioeconômico mais alto (OR ajustado: 1,34 – IC95% 1,20;1,50) foi fator associado à não vacinação. Conclusão As baixas coberturas destacam a necessidade de entender melhor as especificidades regionais e as desigualdades sociais.

Resumo Antecedentes O envelhecimento populacional e as consequências do isolamento social após a pandemia de COVID-19 tornaram relevante investigar a viabilidade, segurança e aderência de intervenções remotas e potenciais efeitos para prevenir declínios funcionais. Objetivo (1) Investigar a viabilidade, segurança e aderência de um protocolo remoto de exercícios físicos e cognitivos; (2) investigar os possíveis efeitos sobre variáveis de cognição e de bem-estar. Métodos Vinte e nove mulheres foram randomicamente divididas em grupo experimental (GE; n= 15) e grupo controle (GC; n= 14). O GE realizou sessões de 40 minutos de exercícios físicos e cognitivos e o GC, 20 minutos de alongamentos. Totalizaram 20 sessões por videoconferência e 20 pelo YouTube, duas vezes por semana. O Teste de Fluência Verbal, o Teste de Dígitos (ordem direta e inversa), a Escala de Depressão Geriátrica (GDS) e o Índice de Bem-Estar (WHO-5) foram aplicados no pré e pós-intervenção, por telefone e formulário digital. Resultados A aderência geral média foi de 82,25% no GE e 74,29% no GC. A ocorrência de eventos adversos (dores musculares leves) foi de 33,3% no GE e 21,4% no GC. O GE teve melhora em fluência verbal e atenção (p ≤ 0.05) e ambos os grupos tiveram melhora significativa nos sintomas depressivos. Conclusão O presente estudo atendeu aos critérios preestabelecidos para a viabilidade, segurança e aderência do programa oferecido entre idosas. Os resultados sugerem que o protocolo combinado tenha maior potencial de aprimorar funções cognitivas. Ambas as intervenções foram benéficas para a percepção subjetiva de bem-estar.

Abstract Background Population aging and the consequences of social distancing after the COVID-19 pandemic make it relevant to investigate the feasibility of remote interventions and their potential effects on averting functional decline. Objective (1) To investigate the feasibility, safety, and adherence of a remote protocol involving physical and cognitive exercises for older women with normal cognition; (2) to examine its effects on cognitive and well-being variables. Methods Twenty-nine women (age ≥ 60 years old) were randomized into experimental group (EG; n= 15) and control group (CG; n= 14). The EG performed a 40-minute session of cognitive and physical exercises, and CG performed a 20-minute stretching session. Both groups performed 20 sessions via videoconference and 20 on YouTube twice a week. The Mini-Mental State Examination, Verbal Fluency Test, Digit Span (direct an inverse order), Geriatric Depression Scale (GDS), and Well-being Index (WHO-5) were applied in pre- and post-interventions by phone. Results Overall adherence was 82.25% in EG and 74.29% in CG. The occurrence of adverse events (mild muscle pain) was 33.3% in EG and 21.4% in CG. The EG improved verbal fluency and attention (p ≤ 0.05); both groups had improved depressive symptoms. Conclusion The present study met the pre-established criteria for feasibility, safety, and adherence to the remote exercise protocol among older women. The results suggest that a combined protocol has more significant potential to improve cognitive function. Both interventions were beneficial in improving the subjective perception of well-being.

Abstract Background Hepatocellular carcinoma (HCC) is a prevalent tumor with high mortality rates. Computed tomography (CT) is crucial in the non-invasive diagnosis of HCC. Recent advancements in artificial intelligence (AI) have shown significant potential in medical imaging analysis. However, developing these AI algorithms is hindered by the scarcity of comprehensive, publicly available liver imaging datasets. Objectives This study aims to detail the tools, data organization, and database structuring used in creating HepatIA, a medical imaging annotation platform and database at a Brazilian tertiary teaching hospital. HepatIA supports liver disease AI research at the institution. Material and methods The authors collected baseline characteristics and CT scans of 656 patients from 2008 to 2021. The database, designed using PostgreSQL and implemented with Django and Vue.js, includes 692 CT volumes from a four-phase abdominal CT protocol. Radiologists made segmentation annotations using the OHIF medical image viewer, incorporating MONAI Label for pre-annotation segmentation models. The annotation process included detailed descriptions of liver morphology and nodule characteristics. Results The HepatIA database currently includes healthy individuals and those with liver diseases such as HCC and cirrhosis. The database dashboard facilitates user interaction with intuitive plots and histograms. Key patient demographics include 64% males and an average age of 56.89 years. The database supports various filters for detailed searches, enhancing research capabilities. Conclusion A comprehensive data structure was successfully created and integrated with the IT systems of a teaching hospital, enabling research on deep learning algorithms applied to abdominal CT scans for investigating hepatic lesions such as HCC.

RESUMO A cidade de São Paulo possui três viveiros municipais de distribuição de exemplares de plantas que atendem à demanda de seus projetos paisagísticos e o aumento da cobertura arbórea. Um deles (Manequinho Lopes) recebe mudas de árvores pelos processos de compensação ambiental contratados pela Secretaria Municipal do Verde e Meio Ambiente (SVMA). Este trabalho teve como objetivo avaliar o cenário da biodiversidade arbórea recebida entre julho de 2013 e julho de 2018 pelo viveiro Manequinho Lopes, como medida de compensação ambiental. Os resultados indicaram que 144.727 mudas de árvores foram recebidas pelo viveiro, com aproximadamente 80% do total pertencendo a apenas 30 espécies, sendo que metade delas pertencem a apenas 10 grupos diferentes. Encontramos apenas duas famílias predominantes: Myrtaceae e Bignoniaceae, evidenciando o futuro risco de homogeneização biótica. Em relação aos atributos ecológicos, constatou-se que 33% das espécies eram zoocóricas, 16% autocóricas e 22% anemocóricas. A maioria deles eram espécimes não ameaçados de extinção. Lopes SVMA.

ABSTRACT São Paulo city has three municipal nurseries for the distribution of urban tree specimens that meet the demand for its public landscape projects and increase in tree covering. One of them (Manequinho Lopes) receives tree seedlings from the environmental compensation processes contracted with the Municipal Secretariat for Green and Environment (MSGE). This paper aimed to evaluate the scenario of tree biodiversity received between July 2013 and July 2018 by the Manequinho Lopes nursery, as a measure of environmental compensation. The results indicated that 144,727 tree seedlings were received by the nursery, with approximately 80% of the total belonging to only 30 species, half of them belonging to only 10 different groups. We found just two predominated families: Myrtaceae and Bignoniaceae, highlighting a biotic homogenization risk. Regarding ecological attributes, it was found that 33% of the species were zoochoric, 16% autochorous and 22% anemochoric. Most of them were non-endangered specimens. covering MSGE. MSGE .

ABSTRACT Serra da Saudade Formation corresponds to the upper part of the stratigraphic column of the Bambuí Group. Few studies have addressed the soil properties and pedogenesis of the pelitic rocks rich in potassium minerals of this formation. This study analyzed siltstone-derived soils, some of which are glauconitic (green siltstone; “verdete”), to understand the role of the main pedogenetic factors and processes in the landscape of the Central-West region of the Minas Gerais State, covered by Cerrado vegetation. Nine soil profiles were described, and their morphological, physical, chemical and mineralogical properties were analyzed. Soils were classified as Neossolos Litólicos (P1, P3, P6, P8 and P9), Cambissolos Háplicos (P2 and P5), Argissolo Vermelho-Amarelo (P4) and Argissolo Acinzentado (P7). The main active pedogenetic processes identified in the study area are melanization, goethization, argiluviation and elutriation. These are essentially controlled by the nature of the parent material and position of the soil in the relief. Soils are typically shallow, dystrophic, highly Al-saturated and contain essentially quartz and micas in the coarse fractions (sand and silt) and illite/glauconite and kaolinite in the clay fraction. In soil environments with siltstone and green siltstone under “dry forests”, the soil water pH was higher and high levels of exchangeable calcium and magnesium, a eutrophic character and high-activity clay were observed. Barium, chromium, lead and zinc contents were high in all studied soils. Green siltstone-derived soils have peculiar physical and chemical properties, divergent from those developed from other glauconitic rocks on the Earth surface. However, greenish tones in horizons are common in all these soils.

ABSTRACT Background: Trachoma is the leading infectious cause of blindness worldwide. It is a neglected tropical disease caused by Chlamydia trachomatis. The objective of this study was to analyze the trachoma-associated morbidity and mortality in Brazil from 2000 to 2022. This ecological time-series study was based on secondary data on trachoma obtained from hospital admissions (trachoma as the primary or secondary cause) and death certificates (trachoma as the underlying or associated cause). Methods: We calculated the sex- and age-standardized rates of hospital admissions and trachoma-specific mortality according to sociodemographic variables and analyzed the spatial distribution. Results: We identified 141/263,292,807 hospital admissions (primary cause: 83.0%) and 126/27,596,830 death certificates (associated cause: 91.3%) related to trachoma. Trachoma-related sequelae were reported in 8.5% of hospital admissions and 6.3% of death certificates. Trachoma was more common in males (hospital admissions and death certificates), people aged ≥70 years (hospital admissions and death certificates), those with brown skin (hospital admissions and death certificates), and those living in the North (hospital admissions) and Northeast (death certificates) regions of Brazil. Conclusions: Despite the relatively low rates of trachoma morbidity in Brazil, the associated mortality rates are of concern. The heterogeneous patterns of occurrence in the country in terms of population and territory reinforce the need to evaluate and monitor the available data, despite the low prevalence, in order to achieve and maintain the elimination targets in Brazil in the future.

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.

Resumo Introdução: O caráter persistente de elevada endemicidade da hanseníase em áreas específicas no Brasil segue um desafio. O reconhecimento de redes de convívio domiciliar (RCD) de casos de hanseníase, com base no entendimento sobre riscos e vulnerabilidades ampliadas, é estratégico para controle. Objetivo: Analisar a ocorrência da hanseníase em diferentes gerações, a densidade de casos e os perfis sociodemográfico e econômico vinculados a redes de convívio domiciliar (RCD) com sobreposição da doença em municípios do Norte e Nordeste do Brasil. Método: Estudo transversal, com dados primários de casos de hanseníase que fazem parte de uma RCD com no mínimo dois casos da doença. Empregou-se regressão logística para estimar razão de chances (OR) com intervalos de 95% de confiança (IC95%). Resultados: Duzentos e trinta e três (233) casos de hanseníase foram abordados, vinculados a 137 RCD. Em 53,2% (n=171) dos casos a doença atingiu duas gerações e em 20,2% (n=47), três gerações. Verificou-se maior chance de acometimento de duas ou mais gerações com diagnóstico apenas entre consanguíneos na RCD (OR-Ajustado= 4,35, IC95% 2,15–8,81) e diagnóstico de outros casos antes e depois (OR-Ajustado =8,51, IC95% 3,52–20,60). A maioria pertence a RCD com mais de três casos, com média de 4,1 casos por RCD (desvio padrão=3,3). Conclusões: O reconhecimento da sobreposição de casos de hanseníase em uma RCD, o número de gerações acometidas e a densidade de casos podem ser utilizados como indicadores-sentinela da situação epidemiológica e da capacidade operacional para a vigilância da hanseníase.

Abstract Background: The persistent high endemicity of leprosy in certain areas of Brazil remains a challenge. Identifying household contact networks (HCN) of leprosy cases, based on an understanding of expanded risks and vulnerabilities, is strategic for control. Objective: To analyze the occurrence of leprosy in different generations, the density of cases, and the sociodemographic and economic profiles linked to household contact networks (HCN) with overlapping disease in municipalities in the North and Northeast of Brazil. Method: Cross-sectional study with primary data from leprosy cases that are part of an HCN with at least two cases of the disease. Logistic regression was used to estimate odds ratios (OR) with 95% confidence intervals (95%CI). Results: Two hundred and thirty-three (233) leprosy cases were addressed, linked to 137 HCN. In 53.2% (n=171) of the cases, the disease affected two generations, and in 20.2% (n=47), three generations. There was a higher chance of affecting two or more generations with diagnosis only among consanguineous individuals in the HCN (adjusted OR=4.35, CI95% 2.15–8.81) and diagnosis of other cases before and after (adjusted OR=8.51, CI95% 3.52–20.60). The majority belonged to HCN with more than three cases, with an average of 4.1 cases per HCN (standard deviation=3.3). Conclusions: The recognition of the overlap of leprosy cases in an HCN, the number of affected generations, and the case density can be used as sentinel indicators of the epidemiological situation and the operational capacity for leprosy surveillance.

RESUMO O objetivo do trabalho foi estudar métodos de produção de mudas de amendoim forrageiro (Arachis pintoi) cv. Belomonte e sua introdução em pasto já estabelecido com capim Tamani. O experimento foi realizado em duas fases. Na primeira fase foi realizada a produção de mudas a partir dos estolões com três tratamentos: estolões produzidos em água; estolões produzidos em solução nutritiva e estolões produzidos com substrato comercial. Para o tratamento com substrato comercial, este não obteve mudas suficientes para a segunda fase do experimento, sendo descartado. A segunda fase consistiu no plantio das mudas em pastagem já estabelecida de capim BRS Tamani. O delineamento foi inteiramente casualizado com três tratamentos: mudas de amendoim produzidas em água, mudas de amendoim produzidas em solução nutritiva e estolão bruto. As variáveis avaliadas foram o índice de sobrevivência de mudas e a sobrevivência e desenvolvimento dos diferentes tipos de mudas enraizadas de amendoim forrageiro aos 30, 60, 90 e 120 dias após plantio. O índice de sobrevivência dos estolões foi superior a 70% para os tratamentos utilizando água pura e solução nutritiva. O comprimento médio dos estolões e o número de folhas por planta, foram superiores para o tratamento utilizando solução nutritiva. No final do experimento, o número de plantas vivas não foi diferente. A produção de mudas enraizadas de amendoim forrageiro pode ser realizada utilizando solução nutritiva pra folhosas ou apenas com água, indicando facilidade na produção. O enraizamento prévio das mudas em solução nutritiva para folhosas favorece o crescimento de estolões e folhas.

ABSTRACT The objective of this study was to explore methods for producing forage peanut (Arachis pintoi) cv. Belomonte seedlings and their introduction into an established pasture with Tamani grass. The experiment was conducted in two phases. In the first phase, seedlings were generated from stolons with three treatments: stolons produced in water; stolons produced in nutrient solution; and stolons produced with commercial substrate. The treatment with commercial substrate did not produce sufficient seedlings for the second phase of the experiment and was, therefore, discontinued. In the second phase, the seedlings were planted in an established pasture of BRS Tamani grass. The experiment was laid out in a completely randomized design with three treatments: peanut seedlings produced in water, peanut seedlings produced in nutrient solution, and raw stolon. The variables evaluated included seedling survival rate and the survival and development of the different types of rooted forage peanut seedlings at 30, 60, 90, and 120 days after planting. Stolon survival rate exceeded 70% for the treatments using pure water and nutrient solution. The average stolon length and the number of leaves per plant were greater for the treatment using the nutrient solution. At the end of the experiment, there was no significant difference in the number of live plants. Forage peanut seedlings can be produced using a nutrient solution for broadleaf plants or simply with water, indicating easy production. Pre-rooting the seedlings in a nutrient solution for broadleaf plants favors the growth of stolons and leaves. Arachis pintoi cv grass phases therefore discontinued 30 60 90 12 planting 70 production Prerooting Pre rooting 3 6 9 1 7

Abstract This study aimed to analyze the physical features and effect of hydroxyapatite (HAp) and Niobium/HAp CaNb2O6/Ca3(PO4)2 composite on critical size defect in rat calvaria. Biomaterials were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), Particle size distribution (PSD) and Scanning Electron Microscopy (SEM). Critical size (8 mm) calvarial defects were created in Wistar rats (n = 24) distributed in three groups (90 days): Control group (CG): critical defect no treatment; HAp group: Hydroxyapatite; CNb/CPO group: CaNb2O6/Ca3(PO4)2 composite. After 90 days, calvaria samples were subjected to histological, and immunohistochemical reactions for osteopontin and osteocalcin, and Micro-CT analyses. XRD analysis confirmed the formation of a crystalline structure of CNb/CPO. XRF measurements confirmed the presence of Nb added in the sample CNb/CPO. Fracture toughness from CNb/CPO composite was 0.82 MPa.m1/2. Micro-CT showed increased trabecular number (p˂0.001), decreased porosities (%) (p˂0.001) and decreased trabecular separation (mm) (p˂0.001) in the CNb/CPO compared to CG group. In CNb/CPO group showed presence of new bone in which connective tissue differentiates to form or indicate a bone matrix score 3 (3-3.75, p˂0.05) and strong immunoexpression of osteopontin (p<0.05). The findings indicate that CNb/CPO showed resistance to the propagation of cracks and stimulated bone formation in calvaria defects in rats.
