ABSTRACT Native Seed Banks of Communities (SBC) are one of the important social technologies that enables the coexistence with the climate in the Semiarid region of Brazil. These banks can supply appropriate seeds due to the genetic improvement carried out by farmers over generations, in addition to the traditional knowledge associated with them. The poor water distribution in part of the states in the Northeast region of Brazil makes family farmers to depend on rainfall and adapted seeds to grow viable crops. In this sense, native seeds are the most suitable due to their robustness and ideal adaptation to the environment and cultivation systems used in the region. Moreover, the conservation of native seeds in germplasm banks is an important strategy for minimizing the impacts of conventional agriculture. Thus, the objective of this study was to map seed banks of communities within the Piemonte Norte do Itapicuru Territory, state of Bahia, Brazil. The research was carried out during the COVID-19 pandemic and presented a qualitative character through a study case methodology. The steps for data collection were: identification of SBC through information from technical advisory entities; georeferencing of the SBC locations; and description of SBC specificities. Eight seed banks were mapped, distributed in three municipalities: Antonio Gonçalves, Campo Formoso, and Pindobaçu. Although the territory is composed of nine municipalities, six of them do not have this technology.

RESUMO O uso de Bancos Comunitários de Sementes (BCS) crioulas constitui-se como uma das importantes tecnologias sociais determinantes para a convivência com o semiárido. Tal estratégia apoia-se no fato de que, tais bancos possibilitam a oferta de sementes apropriadas, em virtude da seleção realizada pelos agricultores ao longo de gerações, bem como de todo conhecimento tradicional associado. Considerando a má distribuição hídrica que acomete em parte dos estados da Região Nordeste do Brasil, os agricultores familiares dependem das chuvas, bem como de sementes adaptadas para viabilizar seus cultivos. Nesse cenário, em razão da rusticidade, as sementes crioulas, são as mais adequadas, pois elas são perfeitamente adaptadas ao clima e ao sistema de cultivo utilizado. Diante dessa problemática, visando minimizar os impactos ocasionados pela agricultura convencional, a citar: a redução da agrobiodiversidade, disponibilidade de sementes no momento adequado para a semeadura, uma das estratégias adotadas é a conservação do germoplasma em bancos ou casa de sementes. O presente estudo teve como objetivo mapear os Bancos Comunitários de Sementes no Território de Identidade Piemonte Norte do Itapicuru, localizado no estado da Bahia. A pesquisa foi realizada durante a pandemia da COVID-19 e apresentou caráter qualitativo, sendo utilizada como metodologia de investigação o estudo de caso. A coleta de dados foi realizada em três etapas e como resultado, foram mapeados oito bancos, distribuídos em três municípios sendo estes: Antônio Gonçalves, Campo Formoso e Pindobaçu. Apesar de o território ser composto por nove municípios percebe-se que seis destes não utilizam essa tecnologia.

Abstract In order to establish a link between the evolutionary history and the photochemical attributes, measurements of chlorophyll (Chl) a fluorescence were made in Cattleya warneri, C. shofieldiana and C. harrisoniana exposed to high irradiance for 5, 35, and 120 min (hereafter referred to as treatments T5, T35, and T120, respectively). The following questions are addressed: (1) Is the increased energy dissipation enough to counterbalance the excess energy that drives photosynthesis at different times of high irradiance exposure? (2) Is there an influence of the incidence and duration of light radiation on Cattleya species in full sunlight, compared to Cattleya species submitted to low irradiance? Higher relative variable fluorescence at the J-step (Vj) values followed by the lower quantum yield of electron transport (ψEo) indicate the accumulation of reduced Quinone A (QA) proportionally of sunflecks exposure time in C. warneri. The higher performance index (PIABS) and plasticity index values in C. schofieldiana indicate higher efficiency in modulating the photosynthetic apparatus under sunflecks. C. harrisoniana shows the lowest plasticity index, suppression of maximum fluorescence (Fm), and no recovery of PIABS after sunflecks. This study evidences the importance of physiological plasticity in the current geographic distribution of Cattleya in response to light pulses in species derived from fragmented habitats and the maintenance of shade to species of more primitive clades.

Resumo Com o objetivo de estabelecer uma ligação entre a história evolutiva e os atributos fotoquímicos, medidas de fluorescência da clorofila (Chl) a foram feitas em Cattleya warneri, C. shofieldiana e C. harrisoniana expostas à alta irradiância por 5, 35 e 120 min (T5, T35 e T120, respectivamente). As seguintes questões são abordadas: (1) O aumento da dissipação de energia é suficiente para contrabalançar o excesso de energia que impulsiona a fotossíntese em diferentes tempos de exposição à alta irradiância? (2) Existe influência da incidência e duração da radiação luminosa em espécies de Cattleya a pleno sol, em comparação com espécies de Cattleya submetidas a baixa irradiância? A maior fluorescência variável relativa no ponto J (Vj) seguida do menor rendimento quântico do transporte de elétrons (ψEo) indicam o acúmulo de Quinona A (QA) reduzida proporcionalmente ao tempo de exposição às manchas solares em C. Waeneri. Os maiores valores de índice de desempenho (PIABS) e do índice de plasticidade em C. schofieldiana indicam maior eficiência na modulação do aparato fotossintético em resposta às manchas solares. C. harrisoniana apresenta menor índice de plasticidade, supressão da fluorescência máxima (Fm) e nenhuma recuperação de PIABS após exposição às manchas solares. Este estudo evidencia a importância da plasticidade fisiológica na distribuição geográfica atual de Cattleya em resposta a pulsos de luz em espécies derivadas de habitats fragmentados e a manutenção do sombreamento para espécies de clados mais primitivos.

Abstract: En | Text: En | PDF: En

The problem of improper disposal of polymeric waste is increasingly in present. Thus, the use of biodegradable polymers is a good alternative, especially for packaging. Compostable and biodegradable polymers such as PHBV can be completely degraded, making them ideal. But the short processability window and fluid instability is an important drawback to the wider application of this polymer in pure form. Production of composite materials has been indicated as a possibility for using this polymer. One source of filler is cellulose, because besides being widely available from agroindustrial waste. In this context, the present work reports the formulation of rigid packaging with PHBV and cellulose waste. An analytical mill was used to promote the dispersion of cellulose fibers. In general, the cellulose fibers increased the Vicat softening point of the polymeric matrix. There were more crystalline structures, according to DSC, and a decrease in impact strength, probably due to increased crystallinity and agglomerate formation. The microscopic analysis indicated greater surface roughness of the composite due to the increase of fibers, resulting in increased contact angle.

Resumen Campos Campos, K. I., Castelli Correia de Campos, L. F., Pereira Morato, M., Fernández Muñoz, M., Tosim, A., Alarcón Segura, K., y Luarte Rocha, C. (2022). Efectividad del lanzamiento de los atletas de goalball en la Liga Nacional de Chile. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-16. El goalball es un deporte paralímpico colectivo con características de oposición, pero sin invasión por parte de los atletas que, a pesar de requerir gran condición física en las acciones ofensivas y defensivas, también se identifica como un deporte táctico, en donde la administración de la técnica en las diversas situaciones del juego determina el éxito en la competencia. El objetivo del estudio fue analizar la efectividad del ataque de la Liga Nacional de goalball de Chile, según tipo de lanzamiento y trayectoria. Se filmaron cuatro partidos de goalball de la fase final de un torneo nacional. Para ello, se utilizó una cámara digital posicionada detrás de un arco ubicado en altura. Para el análisis de los partidos se utilizaron los diagramas propuestos por Morato et al. (2016) y Morato (2012). Los datos se transcribieron de forma computacional a una planilla, para luego ser analizados descriptivamente. El lanzamiento frontal (FRO) fue el que más se utilizó (88.9%), con una tasa de efectividad del 6.2%. Se realizaron trayectorias más largas en diagonales cortas (DC) y paralelas (PA) (31.3% y 23.2%, respectivamente). El lanzamiento de FRO se dirigió en DC (34.5%) y PA (22.4%), mientras que, por otro lado, los lanzamientos con giro (GIR) se dirigieron preferentemente en PA (30.4%) y DC (29.1%). El lanzamiento FRO fue más efectivo en PA (10.6%), mientras que el lanzamiento GIR fue más efectivo en diagonales medias (DM) (12.5%). Las posiciones laterales ejecutan lanzamientos, preferentemente FRO; pero en defensa, las posiciones centrales son protagonistas. Los lanzamientos son más efectivos cuando se dirigen en PA y DC.

Abstract Campos Campos, K. I., Castelli Correia de Campos, L. F., Pereira Morato, M., Fernández Muñoz, M., Tosim, A., Alarcón Segura, K., y Luarte Rocha, C. (2022). Effectiveness of goalball athletes throwing in the Chilean National League. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-16. Goalball is a collective Paralympic sport with oppositional characteristics but without invasion by the athletes that, despite requiring great physical condition in offensive and defensive actions, is also identified as a tactical sport, where the administration of technique in the various game situations determines success in competition. The objective of the study was to analyze the effectiveness of the attack of the Chilean National Goalball League, according to type of shot and trajectory. Four Goalball matches of the final phase of a national tournament were filmed. For this, a digital camera was used behind an arch located in height. The matches were analyzed following the diagrams proposed by Morato et al. (2016) and Morato (2012). The front throw (FRO) was used the most (88.9%) with an effectiveness rate of 6.2%. Longer trajectories were made in short diagonals (DC) and parallel (PA) (31.3% and 23.2%, respectively). The FRO throw was directed in DC (34.5%) and PA (22.4%), while on the other hand, the spinning throws (GIR) were directed preferably in PA (30.4%) and DC (29.1%). The FRO throw was more effective in PA (10.6%), whereas the SP throw was more effective in the middle diagonal (DM) (12.5%). The lateral positions execute throws, preferably FRO, but in defense the central positions are protagonists. Throws are most effective when they are directed in PA and DC.

Abstract: En | Text: En | PDF: En

Objective: To evaluate body dissatisfaction and distorted body self-image in women with prolactinoma. Methods: Body dissatisfaction and distorted body self-image were evaluated in 80 women with prolactinoma. All patients were in menacme, 34% had normal body mass index (BMI), and 66% were overweight. Most patients (56.2%) had normal prolactin (PRL) levels and no hyperprolactinemia symptoms (52.5%). The Body Shape Questionnaire (BSQ) was used to assess the patients’ dissatisfaction with and concern about their physical form, and the Stunkard Figure Rating Scale (FRS) was used to assess body dissatisfaction and distorted body self-image. The patients were divided according to PRL level (normal vs. elevated) and the presence or absence of prolactinoma symptoms. Results: The normal and elevated PRL groups had similar incidences of body dissatisfaction and distorted body self-image. However, symptomatic patients reported a higher incidence of dissatisfaction than asymptomatic patients. Distorted body self-image was less common among symptomatic patients. Conclusion: Symptomatic patients showed higher body dissatisfaction, but lower body self-image distortion. The presence of symptoms may have been responsible for increased body awareness. The perception of body shape could have triggered feelings of dissatisfaction compared to an ideal lean body. Therefore, a distorted body self-image might not necessarily result in body dissatisfaction in women with prolactinomas.

Abstract: En | Text: En | PDF: En

The cosmetic modification of hair is a very common procedure used to mask or cover evidence at a crime scene. Deoxyribonucleic acid (DNA) tests are expensive and require good-quality collection of samples and a database profile. To overcome these challenges, direct analysis was performed on a large set of hair strands collected from individuals, denoted original samples, and the data were compared with those of the same samples after cosmetic modification performed by bleaching the samples in the laboratory. A total of 127 samples were evaluated in this study using two analytical techniques, wavelength-dispersive X-ray fluorescence (WDXRF) and laser-induced breakdown spectroscopy (LIBS). Instead of testing many algorithms to develop classification models for the original and bleached samples, a recent method was applied that combines information from 17 classifiers. Data fusion was also evaluated to improve the accuracy of the classification model, which was higher than 99.2%, with no requirements to select eigenvectors or thresholds.

RESUMO O objetivo do presente trabalho foi avaliar o efeito do extrato de Allamanda blanchetti (Ab) e do indutor de resistência acibenzolar-S-metil (ASM) no controle de Curvularia eragrostidis e na indução de mecanismos de resistência em mudas de inhame cv. São Tomé (Dioscorea alata). O isolado de C. eragrostidis foi obtido a partir de folhas de inhame com sintomas da doença. Crescimento micelial e esporulação do fungo foram avaliados por meio da adição dos tratamentos [extrato de A. blanchetti 10, 100, 500 e 1000 ppm, ASM (200 mg.L-1), fungicida Mancozebe (200 g.ha-1) e testemunha composta por água destilada] ao meio BDA. Em casa de vegetação, mudas com 60 dias de idade foram pulverizadas com os tratamentos em ambas as faces da folha até o ponto de escorrimento, n os intervalos de 0, 24, 48, 96 e 192 h, seguindo-se a pulverização com suspensão de esporos (1x105 conídios.mL-1). A atividade das enzimas peroxidase, fenilalanina amônia liase (FAL) e β-1,3-glucanase foram analisadas em relação ao tempo de aplicação dos tratamentos. Não houve ação fungitóxica in vitro dos tratamentos a C. eragrostidis. O extrato de Ab e o ASM reduziram a incidência e a severidade da doença, bem como promoveram o aumento na atividade das enzimas peroxidases, FAL e β-1,3-glucanase, quando aplicados antes da inoculação com o patógeno. Estes resultados indicam o potencial de A. blanchetti no controle de C. eragrostidis em plantas de inhame pela ativação de mecanismos de defesa.

ABSTRACT The aim of this study was to evaluate the effect of both the extract from Allamanda blanchetti (Ab) and the resistance inducer acibenzolar-S-methyl (ASM) on the control of Curvularia eragrostidis and on the induction of resistance mechanisms in seedlings of yam cv. São Tomé (Dioscorea alata). The isolate of C. eragrostidis was obtained from yam leaves with disease symptoms. Mycelial growth and sporulation were evaluated by adding treatments [extract of A. blanchetti 100, 500 and 1000 ppm, ASM (200 mg.L-1), fungicide Mancozeb® (200 g.ha-1), and control consisting of distilled water] to PDA medium. In a greenhouse, 60-day-old seedlings were sprayed with the treatments on both sides of their leaves to the point of runoff, at 0, 24, 48, 96 and 192h intervals, followed by spraying with a spore suspension (1x105 conidia.mL-1). The activity of peroxidases, phenylalanine ammonia lyase (PAL) and β-1,3-glucanase was analyzed in relation to the time of application of treatments. There was no in vitro fungitoxic action of treatments on C. eragrostidis. Extract of Ab and ASM reduced the disease incidence and severity and increased the activity of peroxidases, PAL and β-1,3-glucanase, when applied prior to inoculation with the pathogen. These results indicate the potential of A. blanchetti for C. eragrostidis control in yam plants by the activation of defense mechanisms.

RESUMO O plaquetograma é um dos componentes do hemograma que inclui a quantificação e a avaliação plaquetária. A presença de artefatos laboratoriais, como as contagens incorretas do número de plaquetas pelos analizadores hematológicos, pode originar casos de pseudotrombocitopenia (15% a 30% de casos de trombocitopenias isoladas observados na rotina laboratorial). A pseudotrombocitopenia induzida pelo anticoagulante ácido etilenodiaminotetracético (EDTA) é um dos casos mais comuns em que a presença do anticoagulante em amostras de sangue pode provocar agregação plaquetária ou satelitismo plaquetário. A observação de forma criteriosa dos dados emitidos pelos analizadores (por exemplo, histograma de plaquetas e flags) é crucial. Outros procedimentos, como a verificação da existência de coágulo na amostra, a repetição da amostra e a visualização de um esfregaço de sangue periférico, além do pedido de nova amostra colhida com outro tipo de anticoagulante, como o citrato, são importantes para confirmar casos de pseudotrombocitopenia.

ABSTRACT The thrombogram is one of the components of the blood count that includes platelet quantification and evaluation. The presence of laboratory artifacts, such as incorrect platelet counts by autoanalyzers, can lead to pseudothrombocytopenia, which is responsible for 15% to 30% of the cases of isolated thrombocytopenia observed in laboratory routine. Pseudothrombocytopenia induced by the anticoagulant ethylenediaminetetraacetic acid (EDTA) is one of the most frequent cases in which the presence of anticoagulant in blood samples can cause platelet aggregation or platelet satellitism. Careful observation of the data emitted by autoanalyzers, such as platelet and flag histograms, is crucial. Other procedures, such as checking for clotting in the sample, repeating the sample and viewing a peripheral blood smear, requesting a new sample taken with another type of anticoagulant, such as citrate, are imperative for the confirmation of cases of pseudothrombocytopenia.

RESUMEN El plaquetograma es uno de los componentes del hemograma que incluye la cuantificación y la evaluación de las plaquetas. La presencia de artefactos de laboratorio, como los recuentos incorrectos del número de plaquetas por los analizadores hematológicos puede originar casos de pseudotrombocitopenia (del 15% al 30% de los casos de trombocitopenias aisladas observados en la rutina del laboratorio). La pseudotrombocitopenia inducida por el anticoagulante ácido etilendiaminotetraacético (EDTA) es uno de los casos más comunes en los que la presencia de anticoagulante con muestras de sangre puede producir agregación plaquetaria o satelitismo plaquetario. La observación criteriosa de los datos emitidos por los autoanalizadores (por ejemplo, histogramas plaquetarios y alarmas) es crucial. Otros procedimientos, como la verificación de la existencia de un coágulo en la muestra, la repetición del frotis de sangre periférica, además de la solicitud de nueva muestra con otro tipo de anticoagulante, como el citrato, son importantes para confirmar casos de pseudotrombocitopenia.

Abstract INTRODUCTION: The Amazon tropical rainforest has the most dense and diverse ecosystem worldwide. A few studies have addressed rodent-borne diseases as potential hazards to humans in this region. METHODS: A retrospective survey was conducted using enzyme-linked immunosorbent assay for detecting mammarenavirus and orthohantavirus antibodies in 206 samples collected from rural settlers of the Brazilian Western Amazonian region. RESULTS: Six (2.91%) individuals in the age group of 16 to 36 years were found to possess antibodies against mammarenavirus. CONCLUSION: Evidence of previous exposure to mammarenavirus in the rural population points to its silent circulation in this region.

Abstract: En | Text: En | PDF: En

Methasterone is a designer anabolic steroid that is prohibited for athletes and is monitored by anti-doping laboratories. In this work, our objective is to discover new human phase I metabolites, define their excretion kinetics for 30 days and analyze their phase II metabolism (sulfate, cysteine and N-acetylcysteine conjugates). Urine samples from four volunteers were analyzed by chromatographic techniques. Through gas chromatography coupled to mass spectrometry analysis it was possible to detect methasterone and its nine phase I metabolites in the urine samples after glucuronide enzymatic hydrolysis, from which one were previously unreported. These nine compounds were not excreted in free form. The new proposed metabolite is 17β-hydroxy-2α,17α-dimethyl-5β-androstan-3-one, obtained from the epimerization at C5. The 3α-hydroxy metabolite, currently monitored by anti-doping laboratories, was the most abundant and was detected for the longest time. Furthermore, four other long-term metabolites were identified. By ultra-performance liquid chromatography coupled to tandem mass spectrometry, only the drug and a known metabolite were detected after glucuronide hydrolysis, and phase II metabolites were not found. Thus, our results contribute to elucidating methasterone metabolism, including long-term metabolites besides of the 3α-hydroxy in routine doping analysis, which is very important due to variation in human metabolism.

Abstract Objective: To evaluate prevalence, clinical manifestations, laboratory abnormalities, treatment and outcome in a multicenter cohort of childhood-onset systemic lupus erythematosus (cSLE) patients with and without panniculitis. Methods: Panniculitis was diagnosed due to painful subcutaneous nodules and/or plaques in deep dermis/subcutaneous tissues and lobular/mixed panniculitis with lymphocytic lobular inflammatory infiltrate in skin biopsy. Statistical analysis was performed using Bonferroni correction(p < 0.004). Results: Panniculitis was observed in 6/847(0.7%) cSLE. Painful subcutaneous erythematosus and indurated nodules were observed in 6/6 panniculitis patients and painful subcutaneous plaques in 4/6. Generalized distribution was evidenced in 3/6 and localized in upper limbs in 2/6 and face in 1/6. Cutaneous hyperpigmentation and/or cutaneous atrophy occurred in 5/6. Histopathology features showed lobular panniculitis without vasculitis in 5/6(one of them had concomitant obliterative vasculopathy due to antiphospholipid syndrome) and panniculitis with vasculitis in 1/6. Comparison between cSLE with panniculitis and 60 cSLE without panniculitis with same disease duration [2.75(0-11.4) vs. 2.83(0-11.8) years,p = 0.297], showed higher frequencies of constitutional involvement (67% vs. 10%,p = 0.003) and leukopenia (67% vs. 7%,p = 0.002). Cutaneous atrophy and hyperpigmentation occurred in 83% of patients. Conclusions: Panniculitis is a rare skin manifestation of cSLE occurring in the first three years of disease with considerable sequelae. The majority of patients have concomitant mild lupus manifestations.

Abstract: En | Text: En | PDF: En

ABSTRACT Considering the constant increase in the waste generation from poultry and pigs’ husbandries, the main contributions of this study were to verify the potential of biogas production through the anaerobic digestion and co-digestion of the residues generated by these two activities, as well as to highlight the recovery of the nutrients contained in the obtained digestate. The wastes used were poultry litters after six, seven and eight production lots, as well as the sifted wastewater from one Piglets Producer Unit (PPU). Higher biogas production (p <0.05) was observed in the treatments in which anaerobic codigestion was used with the swine wastewater (SW): 0.179; 0.158 and 0.117 m3 per kg of total solids (TS) added for poultry litters with six, seven and eight lots, respectively. It was concluded that the anaerobic co-digestion between the poultry litter and sifted swine wastewater is the best option for energy and nutrient recycling. No positive relationships were observed in the increase in the number of reuses of litter in the production of biogas and in the concentration of nutrients in the digestate.
