ABSTRACT The aim of this study was to evaluate agronomic performance in cultivars of the Cavendish banana under the soil and climate conditions of the microregion of Assis in the state of São Paulo over three production cycles. The experiment was set up at the Fazenda São José Farm, Água do Pau d´Alho, in Palmital, São Paulo. The Grande Naine, IAC2001 and FHIA02 cultivars were evaluated, considering the following variables: cultivar; plant height; pseudostem perimeter; number of leaves at flowering and harvest; number of days from planting to flowering, from planting to harvest, and from flowering to harvest; weight of the bunch, stalk and fruit per bunch; number of hands per bunch; productivity of the fruit and pulp; weight and number of fingers on the second hand; weight, length and diameter of the finger; pulp diameter; and weight and thickness of the peel. The data were subjected to multivariate statistical techniques (principal component factor analysis, tree clustering, two-way joining, and correspondence). The results showed the extraction of three principal factors that accounted for 89.63% of the total variance of the characteristics under analysis: banana production (Factor 1), vegetative development (Factor 2), and cultivars and fruit diameter (Factor 3). The productive performance of the FHIA02 cultivar was homogeneous and inferior to that of the other cultivars, as seen in the two-way joining cluster analysis. Only the Grande Naine and IAC2001 cultivars are recommended for cultivation in the micro-region of Assis, São Paulo, with Grande Naine showing the largest fruit and, especially, the largest pulp diameter.

Abstract This study aimed to use the petiole residues of miriti to partially replace pine wood and evaluate the effects of this incorporation on the physical and mechanical properties of the particleboards. Panels were produced with 0, 25, 50, and 75% of miriti in partial replacement of wood and 12% of urea-formaldehyde adhesive. The chemical-physical properties of miriti residues showed potential particleboard production as they were similar to those of pinewood. For the physical properties, the panels were classified as low density. There was an increase in the compression ratio and, consequently, in the hygroscopicity . For the mechanical properties, it was observed that the modulus of elasticity (MOE) and modulus of rupture (MOR) did not show any statistical differences. For perpendicular traction (PT), there was a significant reduction in 50%. Considering a general analysis of the physical and mechanical properties, up to 40% of mirti can be substituted, as in this situation they meet the properties mentioned in CS-236-66, except for PT for commercialization of the panels.

Resumo O objetivo deste trabalho foi utilizar os resíduos do pecíolo do miriti em substituição parcial da madeira de pinus e avaliar os efeitos dessa incorporação nas propriedades físicas e mecânicas dos painéis aglomerados. Os painéis foram produzidos com 0, 25, 50 e 75% de miriti em substituição parcial de madeira e 12% de adesivo uréia-formaldeído. As propriedades físico-químicas dos resíduos de miriti mostraram potencial de produção de aglomerados, uma vez que foram semelhantes às do pinus. Quanto às propriedades físicas, os painéis foram classificados como de baixa densidade. Houve aumento na taxa de compressão e, consequentemente, na higroscopicidade. Para as propriedades mecânicas, observou-se que o módulo de elasticidade (MOE) e o módulo de ruptura (MOR) não houve diferença estatística. Para tração perpendicular (TP) houve redução significativa de 50%. Considerando uma análise geral das propriedades físicas e mecânicas, é possível uma substituição em até 40% de miriti, pois nessa situação atendem as propriedades mencionadas na CS-236-66, com exceção da TP para a comercialização dos painéis.

Abstract: This work aimed to evaluate the physical-mechanical properties of Pinus oocarpa wood agglomerated panels produced with different levels (0 %, 25 %, 50 %, 75 % and 100 %) of wood replacement with bean residues. For this purpose, Pinus oocarpa wood and the agricultural residue were reduced into particles and their properties of apparent density, extractives, lignin and ash content of these raw materials were determined. Then, the particles were dried to a 3 % humidity and granulometrically selected to produce panels with a density of 0,60 g/cm3. These particles were bonded using 12 % urea-formaldehyde adhesive, pressed, following normative dimensions (250 mm x 250 mm x 15 mm (width, length, and thickness)), and kept in a climate-controlled environment (20 ºC ± 2 ºC and 65 % ± 5 % RH) until the physical and mechanical tests were carried out. The research results indicated that the particles from bean residues in comparison with Pinus oocarpa wood, presented low density, lignin and holocellulose values, and higher extractives data. Furthermore, regarding the characterization of the panels, there was a trend towards uniformity in the apparent density values, an increase in the properties of compact ratio, water absorption and thickness swelling, and a decrease in their mechanical properties associated with the increase in the by-product addition to the panels. Therefore, new studies are necessary, seeking a larger study and greater knowledge of the addition effects of bean residues in particulate panels, aiming the dissemination of this sustainable process on large scale.

Abstract The main purpose of this study was to answer the question: “Can radiotherapy cause changes in the dental pulp condition of patients treated with irradiation in the head and neck region?” Clinical observational studies in adults with head and neck cancer undergoing treatment with ionizing radiation, longitudinal or cross-sectional follow-up to measure oxygen saturation (SpO2), and/or pulp sensitivity test to cold stimulation, were considered eligible. A systematic literature search was performed in six different databases, including the gray literature, and in article references. Two independent evaluators selected the studies, extracted the data, recorded the data on electronic spreadsheets, and then evaluated the methodological quality using the Checklist for Quasi-Experimental Studies tool devised by JBI. The data were assessed qualitatively using the Synthesis Without Metanalysis (SWiM) guidelines. After removing the duplicate articles, carefully analyzing the titles and abstracts, and reading the papers in full, seven studies were included. Four of the studies evaluated applied the cold sensitivity test, two associated pulse oximetry and cold sensitivity, and only one used just pulse oximetry. Evaluation using the cold sensitivity test and pulse oximetry in the initial periods before radiotherapy showed a decrease in the sensitive response and in SpO2 levels during a maximum period of 1 year. However, analyses thereafter indicated a normal response in both tests from 5 to 6 years after the end of radiotherapy treatment. Radiotherapy causes changes in pulp behavior patterns in the short term; however, recovery and return to average values occurs after long periods.

ABSTRACT This work aimed to evaluate the effect of nitrogen dose management on the growth responses and physiological performance of barley seeds. Two barley cultivars (BRS Brau and BRS Cauê) and four nitrogen doses were used. The experimental design consisted of randomized blocks in a 2 X 4 factorial scheme (cultivars BRS Brau and BRS Cauê x nitrogen doses 120, 150, 180, and 210 kg ha-1). Successive collections of primary data were performed every fourteen days for growth analysis. The analyzed variables were total dry matter, dry matter production and relative growth rate, assimilated partition, and seed electrical conductivity. Increasing nitrogen doses caused a temporal-quantitative difference in growth, partition, and the accelerated aging test of barley seeds. The 150 kg ha-1 N dose resulted in total dry matter over time (Wt) superiority for both evaluated cultivars. The variable dry matter production rate achieved an increase with the 150 kg ha-1 N dose at 70 days after emergence (DAE) for BRS Brau and at 56 DAE for BRS Cauê supporting Wt. The 180 and 150 kg ha-1 N doses increased the relative growth rate for BRS Brau and BRS Cauê.

RESUMEN Este trabajo tuvo como objetivo evaluar el efecto del manejo de las dosis de nitrógeno en las respuestas de crecimiento y el rendimiento fisiológico de las semillas de cebada. Se utilizaron dos cultivares de cebada (BRS Brau and BRS Cauê) y cuatro dosis de nitrógeno. El diseño experimental consistió en bloques al azar en un esquema factorial 2 X 4 (cultivares BRS Brau y BRS Cauê x dosis de nitrógeno 120, 150, 180 y 210 kg ha-1). Se realizaron recolecciones sucesivas de datos primarios cada catorce días para el análisis de crecimiento. Las variables analizadas fueron materia seca total, producción de materia seca y tasa de crecimiento relativa, partición asimilada y conductividad eléctrica de las semillas. El aumento de las dosis de nitrógeno causa una diferencia cuantitativa-temporal en el crecimiento, partición y la prueba de envejecimiento acelerado de las semillas de cebada. La dosis de 150 kg ha-1 N resultó en una superioridad total de la materia seca en el tiempo (Wt) para ambos cultivares evaluados. La tasa variable de producción de materia seca logró un aumento para la dosis de 150 kg ha-1 N a los 70 días después de la germinación (DAE) para BRS Brau y a 56 DAE para BRS Cauê apoyando Wt. Las dosis de 180 y 150 kg ha-1 N aumentaron la tasa de crecimiento relativo para BRS Brau y BRS Cauê.

RESUMO Paciente feminina de 38 anos com queixa de fotopsias e perda visual indolor em seu olho direito 2 semanas após ter recebido a primeira dose de vacina de vírus inativo para COVID-19 (Sinovac/China National Pharmaceutical Group). Ao exame Oftalmológico, apresentava padrão granular macular, múltiplas lesões cinza-esbranquiçadas no polo posterior, associado à reação vítrea inflamatória. O diagnóstico de múltiplos pontos brancos evanescentes foi realizado após análise multimodal. A paciente foi tratada com corticosteroides sistêmico e evoluiu com melhora da acuidade visual e do quadro clínico.

ABSTRACT A 38-year-old woman presented with photopsias and progressive but painless loss of vision in her right eye. Of note, she had received the first dose of inactivated COVID-19 vaccine (Sinovac/China National Pharmaceutical Group) 2 weeks prior to the onset of symptoms. Ophthalmic evaluation revealed a wreath-like foveal pattern and multiple gray-white dots throughout the posterior pole associated with discrete vitreous inflammatory reaction. Multimodal imaging analysis confirmed a diagnosis of multiple evanescent white dot syndrome. The patient underwent treatment with corticosteroids and, over the following weeks, her visual acuity improved to standard pattern.

Resumo Introdução: A tuberculose (TB) é uma possível complicação grave do transplante de órgãos sólidos, associada à alta mortalidade e morbidade. A TB pós-transplante tem patogênese variada com muitas abordagens para sua prevenção, que é a forma mais importante de reduzir sua incidência. O tratamento da TB em receptores de órgãos é um desafio devido à toxicidade dos medicamentos e à interação com imunossupressores. Relato de caso: uma mulher de 18 anos que foi submetida a transplante renal de um doador falecido e recebeu alta com função renal adequada foi readmitida no 37º dia de pós-operatório com febre. A TC mostrou sinais de TB miliar e coleção de fluidos além de fistulização do enxerto através da pele. A paciente apresentou BAAR positivo no fluido drenado e bacilo de Koch na urina. Ela foi tratada com um esquema de quatro medicamentos (rifampicina, isoniazida, pirazinamida e etambutol), com ótima resposta e função de enxerto preservada. Fomos informados de que o receptor do rim contralateral também apresentou TB pós-transplante, implicando em uma origem derivada do doador. Conclusão: A TB é um importante diagnóstico diferencial para complicações infecciosas em pacientes após transplante de órgãos sólidos, especialmente em regiões endêmicas. Sua apresentação clínica inicial pode não ser específica e deve ser suspeitada na presença de febre ou formação de coleções de fluidos. A suspeita de TB é a chave para o diagnóstico precoce e desfechos satisfatórios na TB pós-transplante.

Abstract Introduction: Tuberculosis (TB) is a possible serious complication of solid organ transplantation, associated with high mortality and morbidity. Post-transplant TB has varied pathogenesis with many approaches to its prevention, which is the most important way to reduce its incidence. Treatment of TB in organ recipients is challenging because of drug toxicity and interaction with immunosuppressants. Case report: an 18-year-old woman that underwent kidney transplantation from a deceased donor and was discharged with fair renal function was readmitted at 37th postoperative day with fever. CT showed signs of miliary TB and fluid collection besides graft fistulization through the skin. The patient presented positive BAAR in the drained fluid and Koch's bacillus in the urine. She was treated with a four-drug regimen (rifampicin, isoniazid, pyrazinamide, and etambutol), with great response and preserved graft function. We were informed that the recipient of the contralateral kidney also presented post-transplant TB, implying in a donor-derived origin. Conclusion: TB is an important differential diagnosis for infectious complications in patients after solid-organ transplantation, especially in endemic regions. Its initial clinical presentation can be unspecific and it should be suspected in the presence of fever or formation of fluid collections. The suspicion of TB is the key to early diagnosis and satisfactory outcomes in post-transplant TB.

Abstract: Non-destructive techniques for characterizing materials in-service have been increasing in importance. Thus, it is relevant to assess the potential of non-destructive techniques for solid materials. This work aimed to determine the modulus of elasticity of Bertholletia excelsa wood using the particle image velocimetry technique and the ultrasound method to compare the results with the conventional methodology. For this purpose, samples of Bertholletia excelsa were made using a circular saw. The samples were evaluated for sound propagation to calculate the modulus of elasticity using ultrasound equipment. Subsequently, they were subjected to the compression parallel to grain test in a universal testing machine. The samples were marked and monitored during the loading session, with the repeated capture of images using a professional camera. The deformation values obtained were used to estimate the modulus of elasticity using the particle image velocimetry technique. The mean values of modulus of elasticity found were 17403 MPa for ultrasound, 15589 MPa for the particle image velocimetry technique, and 15333 MPa for the universal testing machine. The particle image velocimetry technique was considered to be statistically similar (Tukey α = 0,05) to the other methods tested. The linear coefficient of determination (R2) between the particle image velocimetry technique and the universal testing machine was 0,95, a high and satisfactory value. Thus, the particle image velocimetry technique and the ultrasound method are valid to estimate the modulus of elasticity of Bertholletia excelsa wood and possibly of woods with similar technological characteristics.

ABSTRACT. The stockpiled forage canopy consists of tillers at different ages, which have specific development patterns. The objective was to understand the development of Urochloa brizantha cv. Marandu during the stockpiling period, by the morphogenic evaluation of tillers at different ages. The experiment was conducted in a completely randomized design, in a split plot scheme, with four replications. Three tillers ages (young, mature and old) and two periods of stockpiling (initial and final) were evaluated. The leaf appearance and elongation rates were higher in young tillers (0.05 tiller-1 day-1 and 0.62 cm tiller-1 day-1, respectively), compared to old tillers (0.02 tiller leaf-1 day-1 and 0.20 cm tiller-1 day-1, respectively). The final leaf length of the tillers' age groups was the same in the beginning of stockpiling. The number of live leaves was lower in the old tillers (2.4), compared to the young (3.6) and mature (4.1) ones, contrary to the stem length. The number of old tillers (800 tillers m-2) was higher than the young (299 tillers m-2) and mature ones (358 tillers m-²). The participation of different age groups of tillers in the canopy influences the development and structure of marandu palisadegrass.

RESUMO Objetivo: Descrever uma técnica cirúrgica inovadora para transplante de olho em um modelo animal em coelhos. Métodos: Seis coelhos machos com Dutch Belted foram submetidos à orbitotomia lateral do olho direito, com ampla exposição da anatomia retrobulbar, dissecção do cone muscular, exposição e secção distal do nervo óptico seguida de anastomose por vicryl (Grupo 1) ou cola de fibrina (Grupo 2). O registro da eletrorretinografia foi realizado antes da secção do nervo óptico e a cada 30 segundos após, para monitorar a função da retina. O olho esquerdo foi usado como grupo controle. Resultados: Após a ressecção do nervo óptico, a estabilidade da amplitude da eletrorretinografia foi perdida no olho direito após 302 segundos no Grupo 1 e após 296 segundos no Grupo 2. O olho esquerdo manteve eletrorretinografia estável por períodos mais longos. Conclusão: O modelo animal de transplante total de olho foi eficaz em descrever uma nova técnica cirúrgica para ser utilizada em laboratório com coelhos, com sucesso do procedimento anatômico. Novos estudos esclarecerão os melhores métodos de anastomose e manutenção da função do órgão receptor.

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left eye was used as control group. Results: After optic nerve resection and anastomosis, stable ERG amplitude of the right eye was lost after 302 seconds in group 1 and after 296 seconds on group 2. Left eye kept longer stable ERG amplitude curves. Conclusions: The animal model of whole eye transplantation was effective in describing a novel technique to be used in rabbits, with success of the anatomic procedure. Further studies will clarify the best anastomosis methods and maintenance of function of the receptor organ. Translational relevance: this animal model of whole eye transplantation provides a novel perspective for blind patients and the research models, since we describe a novel mammal animal model. This model can be used as basis of a human model of whole eye transplantation in future studies.

Resumo A caracterização de cultivares de bananeiras constitui etapa importante, que permite identificar materiais adaptados para determinada região. O objetivo foi avaliar o desempenho agronômico nas condições edafoclimáticas da microrregião geográfica de Assis-SP, durante os três primeiros ciclos de produção. O experimento foi instalado na Fazenda São José, Palmital-SP, sendo avaliadas 10 cultivares (Grande Naine, IAC 2001, FHIA 02, Bucaneiro, FHIA 17, Calypso, Ambrosia, Thap Maeo, BRS Princesa e Caipira), durante três ciclos produtivos. O delineamento experimental foi em blocos casualizados, com quatro repetições e parcelas de 8,75 m2, compostas por 5 plantas. As variáveis avaliadas foram: altura, perímetro do pseudocaule, número de folhas no florescimento e colheita, massa do cacho, número de pencas por cacho, produtividade de frutos e polpa. Os resultados foram submetidos à análise de variância, aos testes de comparação de médias e à análise multivariada de agrupamentos ou “tree clustering”. As cultivares Grande Naine e IAC 2001, do subgrupo Cavendish, são as mais indicadas para o cultivo na microrregião geográfica de Assis-SP, considerando o desempenho produtivo nos ciclos avaliados.

Abstract The characterization of banana cultivars is an important stage, which allows the identification of materials adapted to a particular region. The aim of this study was to evaluate the agronomic performance in the edaphoclimatic conditions of the geographic microregion of Assis, State of São Paulo, during the first three production cycles. The experiment was installed at São José Farm, Palmital, SP, where ten banana cultivars (Grande Naine, IAC 2001, FHIA 02, Bucaneiro, FHIA 17, Calypso, Ambrosia, Thap Maeo, BRS Princesa and Caipira) were evaluated during the three production cycles. The experimental design was in randomized blocks, with four replicates, each plot with 8.75 m2 and 5 plants per plot. The evaluated variables were plant height, pseudostem perimeter, number of leaves at flowering and harvesting, bunch mass, number of hands per bunch, fruit and pulp yield. Results were submitted to analysis of variance, means comparison tests and multivariate clustering or tree clustering analysis. ‘Grande Naine’ and ‘IAC 2001’ cultivars, as well as those of the Cavendish subgroup, are the most suitable for cultivation in the geographic microregion of Assis, SP, considering production performance in the evaluated production cycles.

RESUMO O presente trabalho tem como objetivo analisar o efeito de diferentes espécies de madeiras e de bambu (Pinus taeda, Cereus jamacaru e Bambusa vulgaris) na hidratação de matrizes cimentícias. Para tanto, os materiais lignocelulósicos foram moídos e caracterizados antes e depois de tratamento em água quente. Posteriormente, o efeito da adição de diferentes níveis (5, 10 e 33,3%) de madeiras, pré-tratadas ou não, em pastas de cimento foram analisados a partir dos ensaios de calorimetria isotérmica e termogravimetria. Os resultados demonstraram que as partículas de cada espécie lignocelulósica apresentaram um aumento das propriedades de umidade e absorção concomitante a diminuição de suas densidades e níveis de extrativos a partir do pré-tratamento aplicado. Os outros componentes químicos destes elementos, majoritariamente, todavia, não foram afetados. Por outro lado, foi observado que quanto maior o teor de tais materiais lignocelulósicos, pré-tratados ou não, nas matrizes de cimento, maior o impacto na hidratação do cimento, segundo o ensaio de calorimetria. Já com relação ao resultado do ensaio de termogravimetria observou-se uma tendência geral, com ou sem pré-tratamento de partículas ou adição de água de compensação, de aumento dos produtos hidratados, fato atribuído, principalmente, a presença de água livre e gases nos materiais lignocelulósicos.

ABSTRACT The present work aims to analyze the effect of different species of wood and bamboo (Pinus taeda, Cereus jamacaru and Bambusa vulgaris) on the hydration of cementitious matrices. For this, the lignocellulosic materials were ground and characterized before and after treatment in hot water. Subsequently, the effect of adding different levels (5, 10 and 33.3%) of wood, pre-treated or not, in cement pastes were analyzed using isothermal calorimetry and thermogravimetry tests. The results showed that the particles of each lignocellulosic species showed an increase in moisture and absorption properties concomitant with a decrease in their densities and extractive levels from the pre-treatment applied. The other chemical components of these elements, however, were mostly unaffected. On the other hand, it was observed that the higher the content of such lignocellulosic materials, pre-treated or not, in the cement matrices, the greater the impact on cement hydration, according to the calorimetry test. Regarding the result of the thermogravimetry test, a general trend was observed, with or without pre-treatment of particles or addition of make-up water, of an increase in hydrated products, a fact mainly attributed to the presence of free water and gases in the lignocellulosic materials.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Abstract: The aim of this work was to verify the ability to use the Particle Image Velocimetry technique for measurements of dimensional variations resulting from wood retractability of Pinus elliottii wood, initially saturated and with the surface marked with multiple dots of ink randomly distributed, was used in this work to apply the Particle Image Velocimetry technique. The specimens were dried and images were captured during the process. The images obtained were processed by the Particle Image Velocimetry algorithm and the deformations that occurred were calculated. For comparison, a conventional method (pachymeter) was used to measure the dimensions of the specimen during drying. The variation in dimensions obtained on the surface of the specimens from the Particle Image Velocimetry technique was 2,28 % for the radial direction and 0,20 % for the longitudinal direction of the fibers. With the standardized method, these values were 2,18 % for the radial direction and 0,21 % for longitudinal. The reduction in the average area of the specimens was 3,85 % by the Particle Image Velocimetry technique and 3,77 % by the conventional methodology. It was concluded that the Particle Image Velocimetry technique was able to accurately measure the displacements on the surface of the Pinus elliottii specimens, resulting in values statistically similar to those reached through the use of the conventional measurement method, demonstrating its reliability.

OBJECTIVE: In 2020, the COVID-19 pandemic brought a work and stress overload to healthcare workers, increasing their vulnerability to mental health impairments. In response, the authors created the COMVC-19 program. The program offered preventive actions and mental health treatment for the 22,000 workers of The Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP). This paper aims to describe its implementation and share what we have learned from this experience. METHODS: Workers were able to easily access the program through a 24/7 hotline. Additionally, a mobile phone app that screened for signs and symptoms of emotional distress and offered psychoeducation and/or referral to treatment was made available. Data from both these sources as well as any subsequent psychiatric evaluations were collected. RESULTS: The first 20 weeks of our project revealed that most participants were female, and part of the nursing staff working directly with COVID-19 patients. The most frequently reported symptoms were: anxiety, depression and sleep disturbances. The most common diagnoses were Adjustment, Anxiety, and Mood disorders. CONCLUSIONS: Implementing a mental health program in a multimodal intervention was feasible in a major quaternary public hospital. Our data also suggests that preventive actions should primarily be aimed at anxiety and depression symptoms, with a particular focus on the nursing staff.
