Worldwide, millions of people suffer from neurological and psychiatric conditions, such as schizophrenia, depression, and neurodegenerative diseases. These conditions are often linked to hyperactivity of monoamine oxidase B (MAO-B) in the brain, and inhibiting this enzyme can reduce oxidative stress, stabilize neurotransmitter levels, and alleviate symptoms. In this context, a pharmacophoric model was created using PharmaGist with 31 hits extracted from BindingDB to enable a pharmacophoric-based search of potential MAO-B inhibitors in ZincPharmer’s chemical space, followed by the building of 10 conformers for each molecule in the software OMEGA, screening for structural and electrostatic similarity to safinamide using ROCS (Rapid overlay of chemical structures) and EON (Electrostatic similarity for lead-hopping), respectively. In addition, the molecular docking with Gold using the score function was performed to rank the ligands with the highest probabilities of affinity to MAO-B and then discriminate those with suitable physical chemical, pharmacokinetic, and toxicological features using the tools QikProp, SwissADME, and DEREK. Four potential ligands with selective MAO-B inhibitor properties were identified, which show promise as future therapeutic agents for MAO-B-related disorders.

Caffeine (CAF) and nicotine (NIC) are emerging contaminants and are among the most consumed substances in the world, making it crucial to monitor these contaminants. In this work, an alternative electrolyte, 2-hydroxyethylammonium acetate (2HEAA) was used for the development of an electroanalytical method for determination and quantification of CAF and NIC, simultaneously, using differential pulse voltammetry (DPV). The system with the 2HEAA electrolyte was characterized by cyclic voltammetry and electrochemical impedance spectroscopy, and the DPV parameters were optimized for the best conditions. The method was validated from a calibration curve obtained which showed limit of detection (LOD) of 0.82 and 6.26 μmol L 1 and limit of quantification (LOQ) of 2.73 and 20.8 μmol L-1 for CAF and NIC, respectively. In the precision analyses, values lower than 10% of relative standard deviation were obtained. In the presence of concomitant inorganic and organic species, the system proved to be selective in the determination of analytes. The method was used to determine the analytes in fortified samples (river water, synthetic urine and commercial milk), obtaining recoveries between 87.25 and 111.40%. The 2HEAA demonstrated high efficiency as an alternative electrolyte with good signal-to-noise ratio, increased analytical sensitivity of the method, in addition to presenting low cost and fast electrolyte preparation.

Alfred Schaeffer (1879-1957) was a German chemist who arrived in Minas Gerais in 1911 hired by the state government to organize the state health service in its newly established capital. He directed the Laboratory of Chemical Analysis of the State, and his analytical methods in dairy and mineral waters became a reference in Brazil. He also became professor of Chemistry at the new Faculty of Medicine of Belo Horizonte and founded the Chemistry Institute of the Engineering School in that city, influencing several students who became important names in Brazilian science. In addition, he was responsible for the assembly and technical coordination of pioneering industries in the dairy and wood distillation sector in the city of Santos Dumont. Later he assumed the post of technical director of Merck, also in Minas Gerais. Moving to Rio de Janeiro, he assumed a chair at the Technical School, working in teaching and research, and remained active even after retiring, publishing in important scientific journals. 18791957 1879 1957 (1879-1957 191 capital State Brazil science addition Dumont Merck Janeiro research retiring journals 1879195 187 195 (1879-195 19 187919 18 (1879-19 1 18791 (1879-1 (1879- (1879 (187 (18 (1 (

Palygoskite pellets were synthesized with lignin and WAX® and subjected to technological characterization for application in the remediation of Pb ions contained in aqueous effluents. X-ray diffraction (XRD) characterization of the palygorskite:lignin:WAX® material in a proportion of 70:15:15 revealed that the heat treatment of the pellets did not compromise the crystalline structure of the palygoskite. Texture analyses demonstrated that the surface area increased after synthesis and heat treatment, thus increasing the adsorption capacity. Regarding porosity, X-ray microtomography revealed that the pellets exhibit an irregular and porous spherical morphology with interconnected pores. Adsorption tests showed a removal of 73% of PbII contained in aqueous effluents after 15 min, with equilibrium reached in 60 min (88.36%). After the adsorption process, the presence of lead in the material was qualitatively confirmed through scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM-EDS) images. The produced pellets exhibit promising adsorbent qualities, such as strength and effective PbII ion adsorption.

ABSTRACT Due to the importance of grain production, and the need to work the soil under limited moisture, the aim of this study was to develop computer software to predict the tractive capacity of wheeled tractors for two types of tyre, the effect of different inflation pressures and levels of soil moisture. A mathematical model was developed to predict the tractive capacity of a 4 x 2 AFT tractor. Software was developed and tested by comparing the computational data with those from tests of a working tractor in the field. The parameters under evaluation were drawbar force and front and rear drive wheel slip. At both moisture levels, the bias tyres had the lowest front to rear slip ratio at the lower pressure; the ratios were similar when equipped with radial tyres. The bias tyres show maximum force at a slip ratio of 1.09 at the higher pressure and 1.03 at the lower, while for the radial tyres the ratio was 1.05 at the higher pressure and 1.07 at the lower. Software was developed to process data from the model, with the results used for estimating the tractive force of the tractor. The tractive force was overestimated by the model, which needs further adjustment for direct application in the field. production tyre field 109 1 09 1.0 103 03 105 05 107 07 10 0 1.

RESUMO: O estudo foi realizado em um ovino, fêmea, de três anos de idade, da raça santa inês, procedente de uma propriedade localizada do município de Santo Antônio de Tauá, oeste do Pará.

ABSTRACT: The study was conducted on a 3-year-old female Santa Inês sheep from a property located in the municipality of Santo Antônio de Tauá, west of Pará. The affected animal had a history of exophthalmos in the left eye, nasal discharge, and breathing difficulty for more than three months. On physical examination, the animal had a low body score, apathy, unilateral facial asymmetry, moderate unilateral left exophthalmos, mixed dyspnea and unilateral profuse serosanguinous nasal discharge. At necropsy, a large nasal mass was observed, predominantly yellowish-white with blackish-red areas, with an irregular, finely granular, moist, and friable surface. The mass invaded from the mucocutaneous junction of the left nostril to the choanae, infiltrated the frontal sinuses, the cribiform plate, and reached the meninges and the frontal portion of the brain. Microscopy of the surface of the nasal epithelium showed severe destruction of the turbinates and epithelia, evidenced by extensive areas of necrosis with a large amount of cellular debris, ulceration, and secondary bacterial infection. In the central nervous system there was pyogranulomatous meningitis with marked vessel congestion, as well as foci of necrosis and granulomatous inflammation. Immunohistochemistry showed intense staining of numerous intralesional hyphae for antibodies against Conidiobolus lamprauges. The diagnosis of granulomatous rhinitis of mycotic origin associated with the Conidiobolus lamprauges was based on epidemiological, clinical-pathological, and immunohistochemical data.

RESUMO: Uma das causas de perda de produtividade em lavouras de cana está associada à espécie Diatraea saccharalis, também conhecida por broca da cana. Portanto, este estudo avaliou a viabilidade do uso de sensores hiperespectrais para obter a resposta espectral foliar da cana-de-açúcar em diferentes períodos de infestações, tanto a nível foliar quanto dossel, a fim de diagnosticar antecipadamente os danos da Diatraea saccharalis. O estudo contou com três variedades de cana-de-açúcar: CTC9003BT, CTC4 e RB966928. Em metade das parcelas foi utilizado o inseticida Altacor® para o controle de pragas. As coletas de dados ocorreram nas fases: brotação, perfilhamento, crescimento de colmos e início da maturação. Para avaliar os efeitos da broca na cana foi coletado os dados referentes ao conteúdo relativo de água (CRA), assinatura espectral foliar em laboratório e dossel, índices de vegetação (NDVI e MCARI), produtividade, pureza e ATR (Açúcar Total Recuperável). O maior CRA encontrado foi para a CTC9003BT (60,15%) sem inseticida e 59,0% com inseticida. As faixas espectrais do visível (400-680 nm) e infravermelho próximo (750-1300 nm) identificaram variações espectrais nas plantas com e sem broca. O percentual de broca apresentou correlações altas e negativas entre a produtividade, NDVI e ATR, com coeficientes de -0,68, -0,76 e -0,76, respectivamente. Os índices NDVI e MCARI foram eficazes na detecção de plantas sob estresse, contudo, sua variação é influenciada por múltiplos fatores, sendo difícil associá-los a um único problema (broca).

ABSTRACT: One of the causes of productivity loss in sugarcane cultivation has been associated with the species Diatraea saccharalis, also known as the sugarcane borer. Therefore, this study evaluated the feasibility of using hyperspectral sensors to obtain the leaf spectral response of sugarcane in different periods of infestation at leaf and canopy levels to diagnose D. saccharalis damage in advance. The study included three varieties of sugarcane: CTC9003BT, CTC4, and RB966928. The insecticide Altacor® was used to control pestsin half of the plots. Data collection occurred at the following stages: sprouting, tillering, stalke longation, and early maturation. Data regarding relative water content (RWC), leaf spectral signature in the laboratory and canopy, vegetation indices (NDVI and MCARI), productivity, purity, and total recoverable sugar (TRS) were collected to evaluate the borer effects on the sugarcane crop. The highest RWC was observed for CTC9003BT (60.15%) without insecticide and 59.0% with insecticide. The visible (400-680 nm) and near-infrared (750-1300 nm) spectral bands identified spectral variations in plants with and without sugarcane borer. The percentage of sugarcane borer showed high and negative correlations between productivity, NDVI, and TRS, with coefficients of -0.68, -0.76, and -0.76, respectively. The NDVI and MCARI indices effectively detect plants under stress, but their variation is influenced by multiple factors, making it difficult to associate them with a single problem (sugarcane borer).

ABSTRACT Exposing seeds to agents that elicit tolerance to abiotic stress, such as phytohormones and organic acids, during hydration and dehydration cycles can determine their response to later stimuli, e.g. exposure to salt stress. The aim of this study was to evaluate the action of priming cycles with different eliciting agents of salt stress tolerance on seeds of the cowpea varieties Sempre Verde and Pingo de Ouro. The seeds were subjected to the following treatments: 0.0 mM NaCl (control); 100 mM NaCl (salt stress); salt stress + three seed-priming cycles (PC) in water; salt stress + PC in gibberellic acid; salt stress + PC in hydrogen peroxide; salt stress + PC in salicylic acid; salt stress + PC in ascorbic acid. The following variables were analysed: germination, growth, dry weight, salt tolerance index, total soluble sugars, total free amino acids and proline. Salt stress (100 mM NaCl) reduced germination, length and biomass accumulation in the Sempre Verde and Pingo de Ouro varieties. These showed the best response to the priming cycles with gibberellic and salicylic acids, which promoted greater germination potential, length and biomass under a salt stress of 100 mM NaCl, affording greater tolerance via osmotic regulation, especially in the Sempre Verde variety. stimuli eg e g e.g treatments 00 0 0. control (control) 10 stress) seedpriming seed (PC water acid peroxide analysed growth weight index sugars proline (10 potential regulation variety (control 1 (1 (

Resumo O concreto têxtil surge como uma alternativa para o reforço de estruturas de concreto armado. Porém, por ser um material relativamente novo, inexiste ainda um órgão ou norma regulamentadora que uniformize os processos de fabricação e de aplicação do material, o que gera diferenças significativas quanto às suas características e propriedades. Sob esta perspectiva, este estudo busca avaliar experimentalmente o desempenho mecânico do concreto têxtil ao ser aplicado como reforço de vigas em concreto armado submetidas ao ensaio de flexão a quatro pontos, utilizando o têxtil de fibra de vidro álcali-resistente de produção brasileira TEXIGLASS AR-360-RA-04. De caráter exploratório, o programa experimental é composto por quatorze vigas reforçadas e uma viga testemunho de seção retangular (120 mm de largura, 200 mm de altura e 1500 mm de comprimento), totalizando quinze vigas. Como variáveis, investigam-se a resistência de ligação na interface têxtil-matriz a partir do (a) tipo de matriz (argamassa polimérica industrializada ou argamassa autoadensável) e do (b) tratamento superficial do têxtil em quatro configurações: têxtil sem revestimento (SR), revestido com epóxi (E), totalmente revestido com epóxi e areia (EA) ou totalmente revestido com epóxi, mas com areia somente nas extremidades (EAP).

Abstract Textile reinforced concrete emerges as an alternative for the strengthening of reinforced concrete structures. However, as a relatively new material, there is still no regulatory body or standardization that standardizes the manufacturing and application processes of the material, which generates significant differences regarding its characteristics and properties. From this perspective, this study seeks to experimentally evaluate the mechanical performance of textile reinforced concrete when applied as reinforcement of reinforced concrete beams subjected to four-point bending tests, using the alkali-resistant fiberglass textile produced in Brazil, TEXIGLASS AR-360-RA-04. As an exploratory study, the experimental program consists of fourteen reinforced beams and one rectangular cross-section reference beam (120 mm wide, 200 mm high, and 1500 mm long), totaling fifteen beams. As variables, the bond strength at the textile-matrix interface is investigated based on (a) the type of matrix (industrialized polymer mortar or self-compacting mortar) and (b) the surface treatment of the textile in four configurations: uncoated textile (UT), coated with epoxy (E), fully coated with epoxy and sand (ES) or fully coated with epoxy and partial sand (EPS). From the results, it was mainly found that: all reinforced beams showed increases in (a) load-carrying capacity, (b) ductility and (c) toughness. Despite the great variability of results, the coating technique in the EPS textile specimens proved promising. structures However material properties perspective fourpoint point tests alkaliresistant alkali resistant Brazil AR360RA04.

Abstract In this technical note, we present an unprecedented database that solves a major problem in the study of electoral strategies: The lack of data to identify where, when, and how candidates carry out activities during the electoral campaign. The Superior Electoral Court (TSE) has made available the records of income and spending during each candidate’s campaign. Among the many pieces of information contained therein, we collected the bank and branch numbers of the beneficiaries of the transactions indicated by the candidates and cross-referenced them with a list of bank branch addresses in Brazil. From these cross-references, we were able to georeference the spending of candidates for the national legislature for the whole country and thus build a proxy of campaign strategies in the electoral contest. This unprecedented database will allow us to advance our understanding of how electoral campaigns are designed, what strategies are employed, and how the relationship between representatives and citizens takes place, since it will be possible to dissociate campaign efforts from the outcome of the election. note where when TSE (TSE candidate s therein crossreferenced cross referenced Brazil crossreferences, crossreferences references, references cross-references contest designed employed place election

ABSTRACT Coffee is a beverage that is widely consumed throughout the world, especially in Brazil. Its high market value makes it a prime target for fraud. To combat this fraud, different methods have been developed and improved over the years to detect potential adulterants in coffee and guarantee its authenticity. Nevertheless, these methods still pose a challenge. Therefore, this work aimed to identify adulteration markers in roasted and ground Arabica coffee using high-performance liquid chromatography (HPLC) to determine the flavonoid and phenolic acid profile.

RESUMO Objetivo: Relatar dois casos de pneumotórax bilateral espontâneo múltiplo sucessivo em crianças com envolvimento pulmonar maciço por histiocitose de células de Langerhans (HCL), alertando para a possibilidade desse diagnóstico diferencial para o pediatra geral. Ademais, casos publicados que descrevem pacientes pediátricos com manifestações pulmonares de HCL foram revisados na literatura. Descrição do caso: Caso 1: Paciente masculino, três anos, com episódio súbito pneumotórax espontâneo à direita, drenado cirurgicamente. Após dois meses, apresentou dois novos episódios de pneumotórax contralateral. Biópsia linfonodal pulmonar revelou diagnóstico de HCL. Foi submetido a cirurgia torácica assistida por vídeo (VATS) bilateral e minitoracotomia com pleurodese mecânica, além de tratamento quimioterápico, necessitando de internação prolongada. Caso 2: Menino, quatro anos, apresentando dispneia progressiva e sibilância por cinco meses. Biópsia pulmonar revelou HCL. Evoluiu com importante desconforto respiratório e pneumotórax direito, necessitando drenagem. Foi realizada pleurodese com nitrato de prata e diferentes esquemas de quimioterapia. Ambos os pacientes evoluíram bem após tratamentos quimioterápicos múltiplos, cirurgias e suporte intensivo. Comentários: A HCL é uma doença desafiadora. Sua manifestação clínica é variável, e o envolvimento pulmonar ocorre em cerca de 10–15% dos casos. Consideram-se o manejo cirúrgico especializado e o suporte multidisciplinar essenciais para o tratamento de pacientes com HCL pulmonar maciça. Ainda que raro, o envolvimento pulmonar maciço por HCL deve ser considerado em quadros de pneumotórax recorrentes em crianças.

ABSTRACT Objective: The objective of this study was to report two cases of successive multiple spontaneous bilateral pneumothorax in children with massive lung involvement due to Langerhans cell histiocytosis (LCH), emphasizing the possibility of this differential diagnosis for the general pediatrician. Additionally, published cases describing pediatric patients with pulmonary manifestations of LCH were reviewed in the literature. Case description: Case #1: A 3-year-old male patient with a sudden episode of spontaneous right-sided pneumothorax, surgically drained. After 2 months, he experienced two new episodes of contralateral pneumothorax. A pulmonary lymph node biopsy revealed the diagnosis of LCH. He underwent bilateral video-assisted thoracic surgery and mini-thoracotomy with mechanical pleurodesis, in addition to chemotherapy, requiring prolonged hospitalization. Case #2: A 4-year-old boy with progressive dyspnea and wheezing for 5 months. A pulmonary biopsy revealed LCH. He developed significant respiratory distress and right pneumothorax, requiring drainage. Silver nitrate pleurodesis and different chemotherapy regimens were performed. Both patients responded well to multiple chemotherapy treatments, surgeries, and intensive care support. Comments: LCH is a challenging disease. Its clinical manifestation is variable, and pulmonary involvement occurs in about 10–15% of cases. We consider specialized surgical management and multidisciplinary support essential for the treatment of patients with massive pulmonary LCH. Although rare, massive pulmonary involvement by LCH should be considered in cases of recurrent pneumothorax in children.

RESUMO: A produção de manga (Mangifera indica) está se expandindo em muitos países e seus resíduos tem o potencial de ser usado para a fabricação de dietas para peixes. Este estudo avaliou a substituição parcial de fubá de milho por farinha de manga (FM) em dietas para piava (Megaleporinus obtusidens) em termos de performance zootécnica, glicose do plasma, enzimas intestinais e análise microbiológica. Piavas (n = 160) foram distribuídas em um esquema completamente randomizado (quatro tratamentos e quatro repetições) e alimentadas por 45 dias com dietas contendo diferentes níveis de inclusão de FM (0, 33, 66 e 100%). Não houve nenhuma contaminação microbiológica (bolor, coliformes totais, Bacillus cereus e Salmonella sp.) na FM. Os fenóis totais e taninos totais foram maiores na dieta com FM (P < 0.05). Dietas com 100% de fubá de milho substituído por MM reduziu a performance de crescimento e aumento a taxa de conversão alimentar (TCA) e os níveis de glicose nos peixes (P < 0.05). De acordo com a análise de regressão de segunda ordem, o nível ideal de inclusão de FM na dieta estimado com base no ganho de peso e o TCA foi de 23,68 e 19,75%, respectivamente (P < 0.05). O aumento gradual dos níveis de FM substituindo fubá de milho na dieta reduziu a atividade das enzimas intestinais amilase, lipase e protease alcalina (P < 0.05). Em conclusão, recomendamos a substituição de 19,75-23,68% de fubá de milho por FM, que pode ser usada nas dietas de piava.

ABSTRACT: Mango (Mangifera indica) production is expanding in many countries, and its discarded residues have the potential to be used in the manufacture of fish diets. This study evaluated replacing part of the corn meal (CM) with mango meal (MM) in diets for piava (Megaleporinus obtusidens) in terms of zootechnical performance, plasma glucose, and intestinal enzymes. Piavas (n = 160) were distributed in a completely randomized design (four treatments and four replications) and were fed for 45 days with diets containing different levels of MM inclusion (0, 33, 66, and 100%). There was no microbiological contamination (mold, total coliforms, Bacillus cereus, and Salmonellasp.) in MM. The MM diet had higher total phenols and total tannins (P < 0.05). Diets with 100% of the CM replaced by MM reduced the growth performance and increased the feed conversion ratio (FCR) and plasma glucose levels in piava (P < 0.05). According to the second-order regression analysis, the optimal level of MM inclusion in the diet estimated based on weight gain and FCR was 23.68 and 19.75%, respectively (P < 0.05). The gradual increase in MM levels replacing CM in the diet reduced the activity of the intestinal enzymes amylase, lipase, and alkaline protease (P < 0.05). In conclusion, we recommended replacing 19.75-23.68% of CM with MM, which can be used in piava diets.
