Abstract Introduction Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates. Methods Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method. Results Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality. Conclusion Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors. 2 NonSeminomatous Non Seminomatous (NSGCT chemotherapy longterm long term 201 2022 KaplanMeier Kaplan Meier method Thirtyseven Thirty seven 318 31 8 31. years Twentytwo Twenty two pathologies 6 types 405 40 5 40. each 70.3 703 70 3 (70. group 39.2 392 39 (39. 37.2 372 37 (37. %, , cervicosternotomy cervico 9.8 98 9 (9. 5.8 58 (5. 3.9 (3. . cases Overall 10year year 10 943 94 94. surgicalrelated related mortality tumors 202 4 70. 7 (70 39.

Resumo: Sementes de mamoeiro possuem barreiras naturais (compostos fenólicos, estrutura da semente e fatores genéticos) que dificultam sua germinação. E o uso de sementes é o principal meio de propagação da espécie, seja para o cultivo comercial,manutenção de germoplasma seja para a seleção de materiais genéticos. Assim, o uso de sementes com qualidade fisiológica (germinação, plântulas normais e velocidadede germinação)é fundamental à produção de plantas vigorosas. Contudo, poucos estudos foram desenvolvidos com intuito de avaliar e de melhorar a qualidade das sementes. Nesta perspectiva,o estudo visa a avaliar a qualidade de sementes em materiais genéticos amplamente utilizados na obtenção de novos genótipos, a fim de identificar materiais superiores e possíveis cruzamentos entre aqueles que possuam alta qualidade fisiológica de sementes.Foram analisados 44 genótipos por caracterização molecular, via marcadores microssatélites (heterozigosidade observada e esperada, número de alelos, índice de informação, índice de fixação, coeficiente de endogamia, estrutura genética e dissimilaridadegenética via agrupamento UPGMA), assim como a determinação da qualidade fisiológica da semente (índice de velocidade de germinação, porcentagem de germinação e plântulas anormais).Dentre os genótipos, 10 possuem germinação acima de 60%, alto índice de velocidade de germinação e baixa porcentagem de plântulas anormais, e podem ser utilizados emcruzamentos para a melhoria na qualidade de sementes. A análise de dissimilaridade foi capaz de evidenciar a dissimilaridade entre os acessos dos grupos Solo e Formosa. O uso do coeficiente de dissimilaridade e do número de alelos compartilhados permitiu identificar 18 possíveis cruzamentos promissores à melhoria na qualidade de sementes de mamoeiro.

Abstract: Papaya seeds have natural barriers (phenolic compounds, seed structure and genetic factors) that make their germination difficult. And the use of seeds is the main means of propagating the species, whether for commercial cultivation, maintenance of germplasm or selection of genetic materials. Thus, the use of seeds with physiological quality (germination, normal seedlings and germination speed) is fundamental to the production of vigorous plants. However, few studies have been developed with the aim of evaluating and improving seed quality. From this perspective, the study aims to evaluate the quality of seeds in genetic materials widely used to obtain new genotypes, in order to identify superior materials and possible crosses between those that have high physiological seed quality. For this purpose, 44 genotypes were analyzed by molecular characterization, via microsatellite markers (observed and expected heterozygosity, number of alleles, information index, fixation index, inbreeding coefficient, genetic structure and genetic dissimilarity via UPGMA grouping), as well as determining physiological quality of the seed (germination speed index, percentage of germination and abnormal seedlings). Among the genotypes, 10 have germination above 60%, a high rate of germination speed and a low percentage of abnormal seedlings, and can be used in crosses to improve seed quality. The dissimilarity analysis was able to highlight the dissimilarity between the accessions of the Solo and Formosa groups. The use of the dissimilarity coefficient and the number of shared alleles made it possible to identify 18 possible crosses promising to improve the quality of papaya seeds.

Assim, o objetivo do presente estudo foi, por meio de uma revisão narrativa da literatura, identificar, analisar e sistematizar os estudos existentes sobre os efeitos da DCR na saúde e qualidade de vida de pessoas com deficiência física. As pesquisas foram conduzidas em bases de dados especializadas, Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) e em bibliotecas digitais de teses e dissertações de inúmeras instituições de ensino superior. Estudos elegíveis incluíram apenas pessoas com deficiência física, assim como tratavam dos efeitos da DCR na saúde e qualidade de vida. Um total de oito estudos foram incluídos na síntese qualitativa. A maior parte dos estudos apresentou uma abordagem qualitativa e delineamento transversal. É possível concluir que a DCR pode trazer inúmeros benefícios para a saúde física, para o funcionamento psicossocial e para a qualidade de vida de pessoas com deficiência física.

ABSTRACT Wheelchair dancing (DCR) is an activity practised mainly by people with physical disabilities. In Brazil, it is an emerging activity lacking investigation and systematisation. Thus, the objective of the present study was, through a narrative review of the literature, to identify, analyse and systematise the existing studies about the effects of DCR on the health and quality of life of people with physical disabilities. The research was driven in specialised databases, the Theses and Dissertations Catalog of the Coordination for the Improvement of Higher Education Personnel (Capes), and digital libraries of theses and dissertations from numerous higher education institutions. Eligible studies included only people with physical disabilities, as well as dealing with the effects of DCR on health and quality of life. A total of eight studies were included in the qualitative synthesis. Most of the studies had a qualitative approach and cross-sectional design. It is possible to conclude that DCR can bring countless benefits to the physical health, psychosocial functioning and quality of life of people with physical disabilities.

ABSTRACT This study was developed to carry out selection, estimate genetic parameters and predict individual genetic values of 55 genotypes from S2 families as well as estimate genetic dissimilarity based on physiological seed attributes. All S2 genotypes evaluated were obtained from self-pollination of S1 genotypes from the guava breeding program. The experiment was laid out in blocks with 55 S2 genotypes and four blocks. Genetic parameters were estimated and the best genotypes were selected based on the genetic value, using the statistical method of mixed models. In addition, genetic divergence was estimated based on the mean Euclidean distance. Although heritability values were considered medium to high magnitude for germination (0.22) and germination speed index (0.35), genetic gains were obtained for all traits. Based on the evaluation of individual BLUPs, the S2 genotypes that contributed to most of the evaluated traits were: 5, 31, 85, 214, 369, 393, 398, 442, 443, 444, 449 and 529, suggesting potential to generate vigorous. Through genetic dissimilarity, it was possible to verify the formation of five distinct groups. Therefore, the selection of divergent genotypes with high average for germination is recommended for the advancement of generation in the guava breeding plant. 5 S attributes selfpollination self pollination program value models addition distance 0.22 022 0 22 (0.22 0.35, 035 0.35 , 35 (0.35) BLUPs 31 85 214 369 393 398 442 443 444 44 529 vigorous groups Therefore plant 0.2 02 2 (0.2 03 0.3 3 (0.35 8 21 36 39 4 52 0.

Resumen Syagrus schizophylla es una especie de palmera ornamental en peligro de extinción. El objetivo de esta investigación fue estudiar los aspectos fisiológicos del crecimiento y la calidad de las plantas producidas bajo gradientes de luz. Los tratamientos de gradientes de luz fueron: G1 - PAR = 1234.10 μmol fotones m-2 s-1, G2 - PAR = 913.16 μmol fotones m-2 s-1, G3 - PAR = 666.34 μmol fotones m-2 s-1), G4 - PAR = 419,56 μmol fotones m-2 s-1 y G5 - PAR = 534,77 μmol fotones m-2 s-1. Antes de aplicar los tratamientos y a los tres, cinco y siete meses de tratamiento, se analizaron la altura de la planta, diámetro del collar, número de hojas, largo del pecíolo, largo y ancho de la hoja), intercambio gaseso, fluorescencia de la clorofila a y color verde de la hoja. Las tasas fotosintéticas netas más altas se observaron en plantas bajo G2, G3 y G4. Em G2 se observaron valores de Fv/Fm superiores a 0,75. En el séptimo mes, los valores estimados del índice SPAD fueron 36 en plantas bajo G2 y 32 en plantas bajo G1. El mejor crecimiento y desarrollo de las plantas se observó en G2 de acuerdo con DQI que muestra que este gradiente debe usarse para plantas destinadas al campo, mientras que G3 sería mejor para plantas destinadas a entornos sombríos.

Abstract This research studied growth and yield of Syagrus schizophylla, an extinction-endangered ornamental palm, grown under five light gradients. The treatments were: G1 - PAR=1234.10 μmol photons m-2 s-1, G2 - PAR=913.16 μmol photons m-2 s-1, G3 - PAR=666.34 μmol photons m-2 s-1, G4 - PAR=419.56 μmol photons m-2 s-1 and G5 - PAR=534.77 μmol photons m-2s-1. Before the experiment and at three, five and seven months of treatment, growth (plant height, collar diameter, number of leaves, petiole length, leaf length and width), gas exchange, chlorophyll a, and leaf green color intensity were assessed. The highest net photosynthetic rates were observed in plants under G2, G3 and G4. Values of maximum quantum efficiency (F v /F m ) over 0.75 were observed under G2. At seven months, estimated SPAD values were 36 in G2 plants and 32 in G1 plants. According to the Dickson quality index (DQI), presented the highest growth and development rates. We conclude that G2 suits plants to be transplanted into the field, whereas G3 would be best for plants grown under shade environments.

ABSTRACT Investigating the physiological potential of seeds and genetic divergence between families is essential to identify promising materials for the generation of improved populations. This study was undertaken to examine the germination potential and estimate genetic divergence between Passiflora full-sib families (FSFs) based on physical and physiological seed traits. The experiment was consisted of 86 FSFs from the first cycle of recurrent selection for resistance to the cowpea aphid-borne mosaic virus. Seeds were evaluated for 19 physical and physiological traits. Dissimilarity estimates were obtained by generalized Mahalanobis distance, and the method unweighted pair group method with arithmetic mean was employed for cluster formation. The FSFs showed high germination potential and seed vigor, with mean of 92.4%, 5.68 e 5.81 cm for germination, germination speed index (GSI) and shoot length of seedlings, respectively. Cluster analysis resulted in four groups formed, being Group I composed by 68 FSF more the control Passiflora edulis. The trait 1,000-seed weight (TSW) was the trait that most contributed to explaining the dissimilarity between families, with 31.9%. The trait GSI (physiological), TSW (physical), as well as traits provided by the GroundEye® system (CIELab-b, hue, and circumference of seeds), were efficient in determining genetic divergence detected between the families of passion fruit. These traits can be taken as a basis in the selection of genotypes with higher physiological seed quality. populations fullsib full sib (FSFs 8 aphidborne aphid borne virus 1 distance formation vigor 924 92 4 92.4% 568 5 5.6 581 81 5.8 (GSI seedlings respectively formed 6 edulis 1,000seed 1000seed 1,000 000 (TSW 319 31 9 31.9% physiological, , (physiological) physical, (physical) GroundEye CIELabb, CIELabb CIELab b, b (CIELab-b hue seeds, seeds) fruit quality 92.4 56 5. 58 000seed 1000 1,00 00 3 31.9 (physiological (physical 92. 100 1,0 0 31. 10 1,

Abstract The germination potential must be considered in the selection of passion fruit genotypes, since vigorous seeds originate seedlings with a higher growth rate, resulting in superior plants with high agronomic performance. This study proposes to estimate genetic parameters and selection gain for seed traits of full-sib families (FSF) of passion fruit under recurrent selection for resistance to the cowpea aphid-borne mosaic virus (CABMV). Physical and physiological seed traits of 86 FSF were evaluated; genetic parameters, genotypic correlations between traits and genetic gains were estimated using four selection indices. There were significant differences and genetic variability between families and positive genetic correlations between variables. The best distribution of genetic gains was obtained by the Mulamba and Mock index, using the heritability coefficient and arbitrary weights. This index selected the best 26 families in terms of seed characteristics to compose the second cycle of recurrent selection for resistance to CABMV. genotypes rate performance fullsib full sib (FSF aphidborne aphid borne CABMV .

Resumo Estudos sobre processos metabólicos e germinabilidade de sementes de espécies nativas ameaçadas de extinção são essenciais para sua conservação. O objetivo deste trabalho foi avaliar o efeito do envelhecimento acelerado na germinação e no perfil proteômico e de poliamina (PAs) em sementes de Cariniana legalis. As sementes foram envelhecidas a 41, 43, 45 e 47°C por 24, 48, 72 e 96 h, sob 100% de umidade relativa, usando um delineamento fatorial inteiramente casualizado. Os dados foram submetidos à análise de variância seguida de teste Tukey. A temperatura de 47°C foi eficiente em simular o envelhecimento das sementes, que não germinaram após 72 h de incubação. Em 41°C, a germinação não mudou significativamente até 96h. A redução na concentração de PAs livres totais, principalmente espermidina e a diminuição no acúmulo de proteínas de choque térmico em sementes envelhecidas à 47°C foram associados à indução do envelhecimento das sementes. Além disso, a diminuição no acúmulo da proteína aconitato hidratase e o aumento no acúmulo da proteína álcool desidrogenase foram associados à perda de germinabilidade das sementes e rápida deterioração em sementes envelhecidas à 47°C. O envelhecimento de sementes de C. legalis está relacionado à alteração no conteúdo de PAs e a alteração de acúmulo de algumas proteínas envolvidas na perda da germinabilidade. conservação (PAs 41 43 4 47C C 47 24 48 7 9 100 relativa casualizado Tukey incubação 41C 41°C 96h totais disso 2 10 1

Abstract Studies on metabolic processes and seed germinability of native endangered species are essential for its conservation. The objective of this work was to evaluate the effect of accelerated aging on germination and on the proteomic and polyamine (PAs) profile in seeds of Cariniana legalis. The seeds were aged at 41, 43, 45 and 47ºC for 24, 48, 72 and 96 h, under 100 % relative humidity using a completely randomized factorial design. The data were submitted to analysis of variance followed by Tukey’s test. The temperature of 47ºC was efficient in simulating seed aging, with no germination after 72 h of incubation. At 41ºC, the germination did not change significantly until 96 h. The reduction in the concentration of total free PAs, mainly spermidine, and the down-accumulation of heat shock proteins in seeds aged at 47°C were associated with induction of seed aging. Furthermore, the down-accumulation of the aconitate hydratase protein and the up-accumulation of the alcohol dehydrogenase protein were associated with loss of seed germinability and rapid deterioration in seeds aged at 47°C. The aging of C. legalis seeds is related to alteration in the contents of PAs and accumulation of some proteins involved with the loss of germinability. conservation (PAs 41 43 4 ºC 24 48 7 9 10 design Tukeys Tukey s test incubation 41ºC spermidine downaccumulation down 47C C 47 Furthermore upaccumulation up 2 1

Resumen Phoenix roebelenii es una especie de palma muy utilizada en Brasil debido a sus hojas exuberantes y su adaptabilidad a diferentes tipos de clima. Por esto, resulta importante obtener información detallada sobre la viabilidad, vigor y longevidad de sus semillas deshi dratadas y almacenadas. La presente investigación comprendió dos etapas. La primera tuvo como objetivo evaluar la respuesta de las semillas a la desecación y almacenamiento con base en protocolos formales. En la segunda, las semillas se desecaron hasta alcanzar el 33, 30, 25, 23, 20, 18, 16, 12, 10 y 7% de contenido de agua. Luego de alcanzar cada nivel de agua establecido para cada tratamiento, las semillas fueron sometidas a pruebas de germi nación. A los 65 días después de la siembra se midió: longitud del sistema radicular y del brote, el área, volumen y diámetro del sistema radicular, la longitud del eófilo y el peso fresco y seco de las plántulas. Por um lado, se observó un aumento significativo en el porcentaje de germinación y en la longitud del eófilo en función del menor contenido de agua de la semilla. Por otro lado, el diámetro del collar disminuyó como consecuencia de la desecación de la semilla.

Abstract Phoenix roebelenii is a palm species widely used in Brazil due to its exuberant leaves and adaptability to different climatic variations. For proper propagation, detailed information about seed viability, vigor and longevity subjected to dehydration and storage is yet to be obtained. For this purpose, the present research comprised two stages. The first one aimed at evaluating the response of seeds to desiccation and storage based on formal protocols. In the second stage, seeds were desiccated to 33, 30, 25, 23, 20, 18, 16, 12, 10 and 7% of water content by monitoring water loss in a convection oven at 35±2°C. After reaching each established water content, the seeds were subjected to germination tests. At 65 days after sowing, root length, root area, volume and diameter, shoot and eophyll length, and total seedling fresh and dry weights, were measured. Significant increases in germination and eophyll length were observed for lower seed water contents. Aversely, collar diameter decreased with seed desiccation.

In this study, quantum-mechanical calculations in the framework of the Density Functional Theory (DFT) were performed to investigate the role of exchange-correlation functional in describing structural, electronic, and magnetic properties of ZnFe2O4. Herein B3LYP, PBE0, B1WC, and WC1LYP functionals implemented in the CRYSTAL17 code were considered due to the different amounts of the exact Hartree-Fock exchange fraction. In particular, the role of HF fraction on ZnFe2O4 properties was addressed for the first time. Indeed, structural, electronic, and magnetic properties indicate the dependence upon the exchange fraction, where WC1LYP with a 16% exact HF exchange exhibits the best performance compared to the other hybrid functionals. The obtained results reveal an excellent agreement for bandgap, local magnetic moment, long-range magnetic ordering, and unit-cell lattice parameters, overcoming previous theoretical studies based on local/semilocal exchange-correlation treatments. These results confirm the importance of hybrid HF/DFT with controlled HF term contribution to describe the essential features of strongly correlated materials.

RESUMO: O acúmulo de nutrients em plantas/frutos variam de acordo com o estádio de desenvolvimento das culturas, sendo que sua quantificação é importante na determinação da exportação de nutrientes para o planejamento da adubação e para o balanceamento de nutrientes. Esse estudo objetivou determinar o acúmulo de nutrientes em diferentes partes dos cachos de Piper nigrum ‘Bragantina’ colhidos em dois estágios de maturação (coloração da casca verde e coloração da casca vermelha). As avaliações foram feitas separadamente nos cachos de Piper nigrum com coloração verde (fruto e pedúnculo) e vermelha (grão, casca e pedúnculo), em que os cachos foram colhidos, secos e as partes foram separadas para análises químicas. N e Mn foram os macro e micronutrientes mais acumulados nos frutos dos cachos com coloração da casca verde e nos grãos dos cachos com coloração da casca vermelha, enquanto K e B foram mais acumulados em outras partes da planta, independente do estágio de maturação. O processo de removação da casca para produção de pimenta branca levou a uma diferença na concentração e no acúmulo de nutrientes nos frutos de pimenta preta e nos grãos de pimenta branca. Uma contribuição significativa para entrada de nutrientes pode ser obtida se as cascas e pedúnculos forem mantidos na área de cultivo, o que diminui a dependência de fertilização, contribuindo para uma agricultura mais sustentável.

ABSTRACT: Nutrients accumulation in plants/fruits varies according to the crop development stage and its quantification is important to determine nutrients exportation for fertilization planning and nutrient balancing. This study determined the accumulation of nutrients in different parts of Piper nigrum ‘Bragantina’ spikes harvested at two ripening stages (still-green and red-colored spikes). Assessments in separate parts of still-green spikes (fruits and peduncles) as well as in red-colored spikes (grains, flesh and peduncles) were performed. Piper nigrum spikes were harvested, dried, and the parts were thereafter separated for chemical analysis. N and Mn were the macro and micronutrient most accumulated in the fruits of still-green spikes and in the grains of red-colored spikes, while K and B were most accumulated in the other parts of black pepper assessed, regardless of the ripening stage. The process of removing the flesh from the fruits for white pepper production led to a difference in nutrient concentration and accumulation between the fruits of still-green spikes and the grains of red-colored spikes. A significant contribution of nutrient input can be achieved by maintained flesh and peduncles in the crop area, decreasing the dependence of external fertilizers and thus contributing to a more sustainable agriculture.

Resumo O uso de dispositivos que produzem vibração estocástica de corpo inteiro como recurso para programas de reabilitação e treinamento foi fundamentado na teoria da ressonância estocástica. Entretanto, a prescrição de programas de reabilitação e treinamento deve ser precedida da verificação da magnitude da vibração imposta e de como ela pode ser afetada pela presença de um indivíduo nos dispositivos. O objetivo deste estudo foi caracterizar e analisar o efeito da massa do indivíduo sobre o estímulo vibratório proporcionado por dispositivos de vibração estocástica de corpo inteiro. A amostra consistiu em 30 repetições para cada um dos 6 níveis de vibração de um dispositivo de vibração estocástica de corpo inteiro (nível 02, 04, 06, 08, 10 e 12), realizados em duas situações experimentais (Sem carga e Carga [70Kg], 35 kg nas superfícies direita e esquerda da plataforma). Para medir a magnitude da vibração, um acelerômetro triaxial foi fixado ao centro do assoalho de uma das superfícies da plataforma. Para os eixos ântero-posterior, látero-lateral e vertical, todas as variáveis mostraram diferenças entre tratamentos, níveis e interação entre fatores experimentais (p<.05), exceto para a variável de deslocamento pico – a – pico (Disp) entre tratamentos (p=.075). A carga interfere com parâmetros de vibração impostos sobre as plataformas de vibração estocástica de corpo inteiro, aumentando a aceleração média (ARMS) e de pico (APEAK) nas direções látero-lateral e ântero-posterior, reduzindo estes mesmos parâmetros na direção vertical.

Abstract The use of devices that produce stochastic whole-body vibration as a resource for rehabilitation and training programs has been founded on the theory of stochastic resonance. However, the prescription of rehabilitation and training programs must be preceded by the verification of imposed-vibration magnitude and of how it can be affected by the presence of an individual on the devices. The aim of this research was to characterize and analyze the effect of an individual's mass on the vibratory stimulus provided by stochastic whole-body vibration (SWBV) devices. The sample consisted of 30 repetitions for each one of the 6 vibration levels of the SWBV device (level 02, 04, 06, 08, 10 and 12), performed in two experimental situations (Without Load; Load [70Kg]; ≈ 35 kg on the right and left surfaces of the platform). For the antero-posterior, latero-lateral, and vertical directions, all variables showed significant differences between treatments, levels and interaction between experimental factors (p<.05), except for the Disp variable between treatments (p=.075). To measure vibration magnitude, a triaxial accelerometer was attached at the center of the board of one of the platform surfaces. Load interferes with parameters of vibration imposed by SWBV platforms, increasing ARMS and APEAK in the latero-lateral and antero-posterior directions, reducing these same parameters in the vertical direction.

ABSTRACT. Sorghum (Sorghum bicolor) is highly sensitive to zinc deficiency in soils, which results in decreased productivity and low-quality agricultural products. Our objective was to evaluate the effects of different zinc doses, applied to seeds, on the physiological quality and initial performance of sorghum plants. Six doses (0, 3.5, 7.0, 14.0, 21.0, and 28.0 g kg-1 seeds) were used and an uncoated control. The Zn coating process used dolomitic limestone as the filler and glue. Laboratory tests were conducted in a completely randomized design and greenhouse experiments were conducted in a randomized block design. The control means were 8, 9, and 14% lower than the maximum, minimum, and total seed area of treatments, respectively, relative to that of treatments. The control differed from other treatments by 10.47 in the speed index of emergence. Zinc at a dose of 28 g kg-1 seeds provided greater production of aerial dry matter, with nutrient content of 75.85 mg kg-1. Zinc on sorghum seeds affected length and dry matter production of aerial parts and roots but did not affect physical characteristics, germination, or emergence time. Applied zinc accumulated mainly in the roots, and promotes changes in Ca and Mg in seeds and other plant parts.
