RESUMO Devido à alta importância do milho como cultura de subsistência e do melhor uso dos recursos hídricos em região semiárida, este estudo teve como objetivo determinar o potencial agronômico, a heterose e a heterobeltiose em diferentes categorias genéticas de híbridos de milho na região semiárida, sob condições de cultivo em sequeiro e irrigação com águas residuais. Foram avaliados 10 genótipos de milho, e suas 45 combinações híbridas, além de cinco genótipos como testemunhas, em regime de sequeiro e sob irrigação com água residuária. Estimou-se a altura da planta, altura da espiga e a produtividade de grãos. Observou-se heterose e heterobeltiose positivas em ambos os ambientes para os híbridos H1, H13, H16, H32, H35, H5, H8 e H9. Os genótipos P2, P3 e P9 mostraram-se como potenciais genitores para criação de novas variedades híbridas de milho no semiárido sergipano. Observou-se maiores desempenhos em regime irrigado com água de reuso, apresentando-se como uma excelente estratégia para a produção de milho em região semiárida. Os híbridos formados pela combinação de variedade × híbrido intervarietal [F1(P1 × P2), F1(P1 × P5)], variedade × híbrido simples [F1(P2 × P6), F1(P2 × P9), F1(P5 × P7) e F1(P5 × P10)], híbrido intervarietal × híbrido simples [F1(P1 × P6) e F1(P1 × P9)] e híbrido duplo [F1(P1 × P10)] sinalizam novas opções de cultivo em região semiárida.
ABSTRACT Considering the high importance of maize as a subsistence crop and the need for optimal use of water resources in semi-arid regions, this study aimed to evaluate the agronomic potential, heterosis, and heterobeltiosis within different genetic categories of maize hybrids grown in a semi-arid region in Sergipe, Brazil, under rainfed and wastewater irrigation systems. Ten maize genotypes, their 45 hybrid combinations, and five commercial genotypes as controls were evaluated based on plant height, ear height, and grain yield. Positive heterosis and heterobeltiosis were found under both growing environments for hybrids H1, H13, H16, H32, H35, H5, H8, and H9. Genotypes P2, P3, and P9 were identified as potential parents for the development of new hybrid maize varieties for growing in the semi-arid region of Sergipe. Better agronomic performance was found for the wastewater irrigation system, indicating an excellent strategy for maize production under semi-arid conditions. The hybrids formed by the combination of variety × intervarietal hybrid [F1 (P1 × P2), F1 (P1 × P5)], variety × single hybrid [F1 (P2 × P6), F1 (P2 × P9), F1 (P5 × P7), and F1 (P5 × P10)], intervarietal hybrid × single hybrid [F1 (P1 × P6) and F1 (P1 × P9)], and double hybrid [F1 (P1 × P10)] indicate promising hybrid candidates for maize crops in semi-arid regions.

RESUMO No ecótono Amazônia-Cerrado, o aumento dos custos com insumos não orgânicos e transporte torna os substratos mais caros, estimulando o uso da biomassa decomposta do caule da palmeira nativa para a produção de mudas. O estudo foi realizado com o objetivo de avaliar as características físico-químicas da biomassa decomposta de babaçu (BDB), carnaúba (BDC) e buriti (BBU) comparado ao substrato comercial (SC) via estatística multivariada. O estudo utilizou um banco de dados composto por 90 substratos, obtidos em fazendas do Maranhão, Brasil. Essas amostras passaram por caracterização físico-química seguindo o protocolo brasileiro para substratos de mudas. Os substratos à base de BDB e BDC apresentam pH e teores de nutrientes em valores aceitáveis, além de menor acidez potencial e elevada saturação por bases em comparação aos substratos BBU e SC. A análise de componentes principais e agrupamento hierárquico revelou similaridades entre BDB, BDC e SC. A biomassa decomposta dos caules das palmeiras babaçu e carnaúba é recomendada como substrato alternativo para produtores de mudas no ecótono Amazônia-Cerrado.
ABSTRACT In the Amazon-Cerrado ecotone, increased costs from non-organic inputs and transportation render substrates more expensive, prompting the use of decomposed biomass from native palm stem for seedlig production. The study was carried out with the objective of evaluate the physicochemical characteristics of the decomposed biomass of babassu palms (BDB), carnauba (BDC), and buriti (BBU) compared to the commercial substrate (SC) via multivariate analysis. This study employed a database comprising 90 substrates, obtained from Maranhão, Brazil farms. These samples underwent physicochemical characterization following the Brazilian protocol for seedling substrates. The substrates based on BDB and BDC have pH and nutrient contents at acceptable values, in addition to lower potential acidity and high base saturation compared to BBU and SC substrates. Principal component analysis and hierarchical clustering revealed similarities between BDB, BDC and SC. Biomass decomposed from the stems of babassu and carnauba palms is recommended as an alternative substrate for seedling producers in the in the Amazon-Cerrado ecotone.

Resumo Introdução: O papel da tomografia computorizada torácica de ultrabaixa dose (ULDCT) em contexto de urgência é desconhecido. Objetivo: Este estudo avaliou a viabilidade da ULDCT em adultos na urgência com suspeita de pneumonia. Foram medidos a dose de radiação, o tempo entre a solicitação e os relatórios do exame, prescrições de antimicrobianos também foram correlacionadas. Métodos: Este estudo avaliou a viabilidade da ULDCT em adultos na urgência com suspeita de pneumonia. Foram medidas a dose de radiação, o tempo entre a solicitação e a disponibilização dos relatórios do exame, e também foram correlacionadas as prescrições de antimicrobianos. Entre outubro de 2017 e dezembro de 2018, incluímos prospectivamente adultos com suspeita de pneumonia adquirida na comunidade, sem diagnóstico definitivo por avaliação clínica. Os critérios de exclusão abrangeram condições clínicas que pudessem afetar a interpretação da imagem. Resultados: Foram incluídos 131 pacientes elegíveis (idade média de 43,5 anos; 57% homens) encaminhados para ULDCT. Dezoito (13,7%) foram excluídos. A dose média de radiação da ULDCT foi de 0,14 mSv. O intervalo de tempo entre a solicitação médica e o resultado da ULDCT foi de 43 minutos. Conclusão: A ULDCT mostrou-se viável para pacientes adultos com suspeita de pneumonia em contexto de urgência. Os relatórios foram disponibilizados num intervalo razoável e os resultados negativos foram associados a uma baixa taxa de prescrição de antibióticos.
Abstract Background: The role of ultra-low-dose chest CT (ULDCT) in the emergency department is unknown. Purpose: This study sought to examine feasibility of ULDCT in adults presenting to the emergency department for whom pneumonia was suspected. Radiation dose and time interval between medical request and ULDCT results were measured, antibiotic prescriptions were correlated. Methods: Between October 2017 and December 2018, we prospectively enrolled consecutive healthy adult patients in a single-center for whom community-acquired pneumonia was suspected and for whom no definitive diagnosis was possible by clinical judgment. Exclusion criteria comprised all chronic conditions that could impact severity and interpretation of image. Results: 131 eligible patients (mean age 43.5 years; 57% men) were enrolled to ULDCT. Eighteen (13.7%) patients were excluded. Average CT radiation dose was 0.14 mSv. Time interval between medical request and ultra-low-dose chest CT result was 43 minutes. Only 15.9% of patients with negative CT received antibiotics. Conclusion: Ultra-low-dose chest CT was feasible for almost all patients in a group of healthy adults presenting to the emergency department with suspected community-acquired pneumonia. Results were made available in a reasonable interval, and negative ones were associated with a low antibiotic prescription rate.

Cancer is one of the major causes of death worldwide, and breast cancer is the most prevalent and deadly type among women. Despite the side effects and the phenomena of chemoresistance associated with the drugs involved, chemotherapy remains the main therapeutic strategy to combat and control breast cancer. Therefore, several new classes of compounds against breast cancer have been explored, in an effort to identify new drug candidates with alternative mechanisms of action. The principal results of such exploration, focusing on caged xanthones, thiosemicarbazones and photosensitizers, are presented in this review, along with the main aspects of the drug discovery process against breast cancer. More specifically, the design, structure-activity relationship investigations and anti-breast cancer properties of these three classes are described and discussed in this work.

Resumo O aumento da modificação dos habitats e da perda de espécies demanda esforços consistentes para descrever e compreender os padrões de biodiversidade. O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.
Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats.

This work aims to determine the best substrate preparation and conversion coatings that may enhance the anti-corrosive performance of alumina film/stainless steel substrate systems in Ringer’s solution. Boehmite, silica, silica/boehmite, and boehmite/silica conversion coatings were deposited on sanded or sandblasted 304L stainless steel samples, and the best results were further covered with alumina film for a long-time exposure evaluation. The best anti-corrosive performances for each substrate preparation were observed for the sandblasted sample covered with silica/boehmite conversion coating (JSB500) and the sanded sample covered with silica (LS500), which showed the highest global resistance (Rg) values (828 Ω.cm2 and 1837 Ω.cm2, respectively) and the smallest values of global capacitance, Cg (2.19 X 10-6 F.cm-2 and 3.37 X 10-9 F.cm-2, respectively). After covering with the alumina film and evaluating for 216 h in the corrosive medium, it was noted an increase in the Rg values for both systems (JSBA500 and LSBA500), likely due to the presence of a corrosion products layer. The presence of iron oxides in these conversion coatings led to a more stable alumina film. Comparing the selected coating systems, the LSBA500 exhibited an improved performance, reaching an increase of 85% in Rg and a decrease of 94% in Cg.

ABSTRACT This study aimed to provide further insight into the evolutionary dynamics of SARS-CoV-2 by analyzing the case of a 40-year-old man who had previously undergone autologous hematopoietic stem cell transplantation due to a diffuse large B-cell lymphoma. He developed a persistent SARS-CoV-2 infection lasting at least 218 days and did not manifest a humoral immune response to the virus during this follow-up period. Whole-genome sequencing and viral cultures confirmed a persistent infection with a replication-positive virus that had undergone genetic variation for at least 196 days after symptom onset.

Abstract This study aims to evaluate the phytochemical properties of Bauhinia holophylla (Bong.) Steud leaf extract, and their impact on maternal reproductive and fetal development in diabetic rats. For this, adult female Wistar rats (100 days of life) received streptozotocin (40 mg/Kg, intraperitoneal) for induction of diabetes, were mated and distributed into four groups: Nondiabetic; Nondiabetic given B. holophylla; Diabetic; and Diabetic given B. holophylla. The plant extract was given by gavage at increasing doses: 200, 400, and 800 mg/Kg. At day 21 of pregnancy, liver and blood samples were obtained for oxidative parameters and biochemical analysis, respectively. The uterus was removed for maternal-fetal outcomes. Phytochemical analysis showed a high content of phenolic components and biogenic amines. B. holophylla extract did not alter the glycemic levels but improved the lipid profile in diabetic animals. Besides that, the number of live fetuses and maternal weight gain were decreased in Diabetic group, and were not observed in animals treated. The group Diabetic treated presented a higher percentage of fetuses classified as adequate for gestational age compared to the Diabetic group. However, the treatment with plant extract caused embryo losses, fetal growth restriction, and teratogenicity in nondiabetic rats. Thus, the indiscriminate consumption requires carefulness.

Abstract It was compared smartphone-based measurements of static balance control and mobility of elderly population with and without type 2 diabetes mellitus (DM2). The present cross-sectional study investigated 73 participants grouped in a control group (n = 36) and a DM2 group (n = 37). Smartphone’s built in inertial sensors were used to record inertial changes of the participants during static balance and mobility (Timed Up and Go test – TUG) tasks. The inertial variations as a function of the time were analyzed and compared between groups. Both groups were matched in age, body mass index, male-female proportion, but DM2 group had significant larger fasting glucose than control group. Additionally, DM2 group had worst static balance control with open and closed eyes than the controls (p < 0.05) as well as they also had longer duration to execute the different events of the mobility test than the controls (p < 0.05). DM2 patients had decline of motor functions compared to controls and the use of bult-in sensors of smartphones was feasible to identify these functional impairments. The easy access of smartphones could be improving the screening of functional impairments in DM2 patients.

ABSTRACT In 2000, Cleide Costa published a paper presenting the state of knowledge of the Neotropical Coleopte ra, with a focus on the Brazilian fauna. Twenty-four years later, thanks to the development of the Coleoptera section of the Taxonomic Catalog of the Brazilian Fauna (CTFB - Catálogo Taxonômico da Fauna do Brasil) through the collaboration of 100 coleopterists from all over the globe, we can build on Costa’s work and present an updated overview of the state of knowledge of the beetles from Brazil. There are currently 35,699 species in 4,958 genera and 116 families known to occur in the country, including representatives of all extant suborders and superfamilies. Our data show that the Brazilian beetle fauna is the richest on the planet, concentrating 9% of the world species diversity, with some estimates accounting to up to 15% of the global total. The most diverse family in numbers of genera is Cerambycidae (1,056 genera), while in number of species it is Chrysomelidae (6,079 species). Conotrachelus Dejean, 1835 (Curculionidae) is the most species-rich genus, with 570 species. The French entomologist Maurice Pic is the author who has contributed the most to the naming of species recorded from Brazil, with 1,794 valid names in 36 families, whereas the Brazilians Ubirajara R. Martins and Maria Helena M. Galileo are the only ones among the top-ten authors to have named species in the 21st century. Currently, approximately 144 new species of Brazilian beetles are described each year, and this average is projected to increase in the next decade to 180 species per year, or about one new Brazilian beetle every two days.

Investigation of corrosion inhibitors on CO2-saturated aqueous solution with O2 contamination is limited. Hence, this study investigated the corrosion behavior of phosphate ester inhibitor towards carbon steel corrosion in a simulated CO2-O2 environment by potentiodynamic polarization technique and electrochemical impedance spectroscopy. It was shown that the PE prevents the corrosion attack in the presence of CO2-O2, reaching an efficiency of 90.7% with 25 ppm in 3.5 wt% NaCl solution at 25 oC. Furthermore, the superficial characterization of carbon steel was studied by scanning electronic microscopy which supported that the inhibitor protects against corrosion. The varying temperatures showed that PE adsorbed on the steel surface by a physical process and obeyed the Langmuir isotherm.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others.

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.
