RESUMO: O objetivo deste estudo foi avaliar a eficácia clínica da aplicação intra-articular de células-tronco mesenquimais alógenas derivadas do tecido adiposo (AD-CTM) no tratamento de cães portadores de osteoartrite secundária a displasia do coxofemoral (DCF). Doze cães de ambos os sexos, diferentes raças, idades e peso, portadores de graus variados de DCF comprovada em radiografia e livres de quaisquer outras alterações clínicas ou ortopédicas, foram utilizados no estudo. Todos os cães foram submetidos a avaliação ortopédica nos dias 0, 30, 60 e 90 após aplicação de AD-CTM na dose de 2 x 106. Além disso, os tutores preencheram a um questionário, baseado no Índice de dor crônica de Helsinque (IDCH) nos mesmos intervalos. Em comparação com o dia 0, observou-se melhora significativa na avalição em locomoção e físico-ortopédica assim como na avaliação dos tutores pelo IDCH ao longo dos 90 dias. Os resultados permitem inferir que as AD-CTM alógenas contribuíram significativamente para a redução dos sinais clínicos comumente associados a DCF durante o período de estudo. Entretanto, há necessidade de estudos de longo prazo para melhor determinação de protocolos terapêuticos baseados no uso de AD-CTM na rotina clínica.

ABSTRACT: This study assessed the efficacy of an intra-articular injection of allogeneic adipose tissue-derived from mesenchymal stem cells (AD-MSCs) for the treatment of hip dysplasia in dogs. The study group included 12 otherwise healthy dogs of different breeds, ages, weights, and degrees of hip dysplasia diagnosed using radiography. An orthopedic assessment was performed on all dogs before and at 30, 60, and 90 days after infusion of AD-MSCs(2 × 106cells). On the same days, each dog’s owner answered a questionnaire based on theHelsinkiChronic Pain Index. The data were converted to ordinal data based on the score for each variable, and the Friedman test for multiple comparisons was used to verify the results. Compared with the corresponding values on day 0, orthopedic and gait assessments and owners’ reported pain indexes improved over the 90-day observation period. These results suggested that treatment with allogeneic AD-MSCs significantly reduced the clinical signs associated with hip dysplasia during the study period. However, long-term studies are needed to determine the optimal therapeutic protocol for routine clinical use of AD-MSCs in hip dysplasia.

Abstract Objective To verify changes in facial soft tissue using the RadiANT-DICOM-viewer and Dolphin Imaging software, through linear measurements of tomographic points in a 3D reconstruction of the face and volumetric evaluation with three-dimensional measurements of the upper airways of patients with transverse maxillary discrepancy undergoing Surgically Assisted Rapid Maxillary Expansion (SARME). Methods Retrospective, transverse, and descriptive study, through the analysis of computed tomography scans of the face of patients with transverse maxillary discrepancy, treated from July 2019 to December 2022. The sample consisted of 15 patients of both sexes, aged 21-42 years old, who underwent surgically assisted rapid maxillary expansion using the transpalatal distractor. Analysis was performed through linear, angular, and three-dimensional measurements in millimeters, in the preoperative and late four-month postoperative period, in frontal 3D tomographic images of the face, in the region of the width of the nose and alar base and also angular measurement in the lateral tomography for the angle nasolabial and upper airways of rhinopharynx, oropharynx and hypopharynx. Results There was an increase in nasal width with an average of 1.3467 mm and an increase in the alar base with an average of 1.7333 mm. A significant difference was found in the pre- and postoperative assessments of the measurements of nasal width, alar base and nasolabial angle, as well as the upper airways in all their extension. The results favour a better understanding of the professional and the patient regarding the diagnosis and management of patients with transverse maxillary width discrepancies. Conclusion Although our study shows an increase in soft tissues after SARME, no aesthetic changes are observed clinically, and all patients report significant respiratory improvement. SARME may therefore contribute to the improvement of professionals working in the field of oral and maxillofacial surgery and orthodontics. Level of evidence: Level 4.

ABSTRACT Background: The riverine communities of the Amazon comprise different social groups that inhabit the rural areas on the banks of rivers and lakes. Residents usually travel by river to rural and urban areas and are then exposed to urbanized diseases such as those caused by arbovirus infection. In Brazil, emerging diseases such as dengue, Zika, chikungunya, and those caused by infection with Oropouche and Mayaro viruses necessitate epidemiological surveillance. This study was aimed at determining the frequency of positivity for immunoglobulin (Ig)G and IgM antibodies against Zika, chikungunya, and dengue viruses and performing molecular analyses to detect viral RNA for the Zika, chikungunya, dengue virus, Oropouche, and Mayaro viruses, in the same serum samples obtained from riverside populations. Methods: This cross-sectional study was conducted in a riverside population in the Humaitá municipality of the Brazilian Amazon. More than 80% of the local population participated in this study. Entomological samples were collected to identify local mosquito vectors. Results: Analysis of 205 human serological samples revealed IgG antibodies against the dengue virus in 85 individuals. No molecular positivity was observed in human samples. Entomological analyses revealed 3,187 Diptera species, with Mansonia being the most frequent genus. Aedes aegypti and Aedes albopictus were not detected in the two collections. Conclusions: IgG antibodies against the dengue virus were highly prevalent, suggesting previous exposure. The absence of the arbovirus vectors Aedes aegypti and Aedes albopictus in the samples supports the hypothesis that the infections recorded likely occurred outside the riverside communities investigated.

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. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

Abstract Perioperative Goal-Directed Therapy (PGDT) has significantly showed to decrease complications and risk of death in high-risk patients according to numerous meta-analyses. The main goal of PGDT is to individualize the therapy with fluids, inotropes, and vasopressors, during and after surgery, according to patients’ needs in order to prevent organic dysfunction development. In this opinion paper we aimed to focus a discussion on possible alternatives to invasive hemodynamic monitoring in low resource settings.

BACKGROUND The Golden Syrian hamster (Mesocricetus auratus), Ferrets (Mustela putorius furo), and macaques have been described as useful laboratory animals naturally susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. OBJECTIVES To study the mechanism of lung injury, we describe the histopathological features of SARS-CoV-2 infection in Golden Syrian hamsters inoculated intranasally with the A.2 Brazilian strain. METHODS Hamsters were intranasally inoculated with the A.2 variant and euthanised at 3-, 5-, 10- and 15-days post-inoculation. The physical examination and body weight were recorded daily. Neutralising antibodies and viral RNA load of the respiratory tract were assessed during necropsies. FINDINGS The coronavirus disease 2019 (COVID-19) model presented body weight loss, high levels of respiratory viral RNA load, severe segmentary pneumonitis, and bronchial fistula besides lymphatic trapping and infiltration, like the human SARS-COV-2 pathogenesis. The presence of subepithelial lymphoeosinophilic infiltrate was highlighted in our results; it contributed to the detachment of SARS-CoV-2 nucleocapsid-positive epithelial cells resulting in the infectious cell plugs. MAIN CONCLUSIONS The SARS-CoV-2 caused segmentary pneumonia and vascular damage. In our comprehension, the infectious cell plugs, as being aspirated from the upper respiratory tract into the terminal bronchial lumen, work as a “Trojan horse”, thus contributing to the dissemination of the SARS-CoV-2 infection into specific regions of the deep lung parenchyma.

ABSTRACT Brazilian Soil Classification System (SiBCS) adopts a hierarchical approach to classify soils using specific diagnostic attributes. Organossolos (Histosols) class is differentiated according to its genesis, especially because the parent material is organic, thus requiring diagnostic attributes that describe the unique properties of soil organic matter (SOM). This study aimed to propose the use of labile organic carbon and the C and N contents of humic fractions and their ratios for the family and series levels of the Brazilian Soil Classification System for Organossolos in high mountainous regions. Quantitative chemical fractionation of SOM was performed to obtain the humic fractions and determine the labile oxidizable carbon in 16 Organossolos profiles from Itatiaia National Park, RJ. Carbon and nitrogen contents of the humic acid, fulvic acid, and humin fractions were obtained, as well as the percentages of these fractions in relation to the total carbon and nitrogen in the soil. Carbon and nitrogen ratios were calculated for each fraction. Results showed little variation in the levels of labile organic carbon between the profiles but a large variation in total carbon and nitrogen levels, especially in the Organossolo Fólico Hêmico lítico profile. The ratios between the carbon and nitrogen of humic acids and fulvic acids (means of HAC/FAC = 1.61 and AHN/FACN = 1.05), carbon and nitrogen of the alkaline extract and humin (means of AEC/HUMC = 0.71 and AEN/HUMN = 0.38), carbon and nitrogen of the alkaline extract, and total carbon and total nitrogen (means of AEC/TC = 0.28 and AEN/TN = 0.19) were effective in determining the humification level of the profiles. This study proposes that the attributes evaluated, especially the ratio between the carbon of the alkaline extract of the humic substances (carbon of the fulvic acid fraction + carbon of the humic acid fraction) and the total soil carbon, as well as the ratio between the C and N of the humin fraction, should be used to define lower categorical levels of Organossolos. This new approach could facilitate the classification of these soils and contribute to a better understanding of the composition of Organossolos in Brazil.

ABSTRACT Traumatic atlanto-occipital dislocation is a rare, severe, and usually fatal injury. In this paper, we report the case of a 28-year-old patient with multiple trauma, who suffered an atlanto-occipital dislocation (AOD) associated with rotatory dislocation at C1-C2, condyle fracture and traumatic brain injury resulting from a car accident, with a cardiopulmonary arrest at the accident site. The patient had motor and sensory deficits, suffering other complications of clinical severity during hospitalization. After two years of surgical treatment follow-up, the patient had a complete recovery of neuromotor and sensory functions. This case demonstrates that neurological recovery with minimal sequelae is possible, even after an unfavorable prognosis resulting from a severe injury with a high risk of death as this kind of trauma. It is essential for health professionals to have the ability to identify and treat AOD, ensuring improved clinical outcomes, reducing mortality and morbidity, and providing a better life to affected patients.

Resumo O tecido tapetal apresenta funções essenciais na formação de células generativas, pois está relacionado a nutrição e desenvolvimento destas nas anteras. Em Bromeliaceae, dentre as poucas espécies descritas, a maioria possui tapete secretor e uma espécie possui tapete invasivo. Neste estudo foram realizadas análises de fases do desenvolvimento de anteras com ênfase ao tapete em Dyckia strehliana com o objetivo de identificar variabilidade em desenvolvimento e estrutura. O material botânico foi coletado as margens do rio Toropi, Rio Grande do Sul, e processados por meio de microtécnica vegetal. Durante a prófase da meiose, as células tapetais de algumas amostras permaneceram parietais enquanto em outras, em número proporcional, inicia-se a invasão no espaço locular, culminando com invasão total durante a fase de micrósporos livres e sem fusão dos protoplastos. A degeneração tapetal está completa antes do início da gametogênese em ambos os tipos. Assim, é possível descrever dois modos de desenvolvimento e estrutura tapetal, um parietal e outro invasivo, embora o tapete permaneça como um tipo secretor geral em ambos os casos. Assim, de acordo com o presente trabalho, os termos invasivo e parietal são indicadores de estados do tapete secretor. generativas Bromeliaceae descritas Toropi Sul vegetal meiose outras proporcional iniciase inicia se locular protoplastos tipos Assim casos trabalho
Abstract Tapetal tissue plays essential roles in the formation of generative cells, as it is related to their nutrition and development in anthers. Among the few species of Bromeliaceae for which tapetal tissue has been describe, most have a secretory tapetum and one has an invasive tapetum. This study analyzed the developmental stages of the anthers of Dyckia strehliana, with emphasis on the tapetum, to identify variability in development and structure. Botanical material was collected on the banks of the Toropi River in the state of Rio Grande do Sul, Brazil, and processed using standard plant micro-techniques. During meiosis prophase, tapetal cells of some samples remained parietal while in the others, a proportional number, the invasion of the locular space begins, culminating in total invasion during the free microspore phase and without fusion of the protoplasts. Tapetal degeneration is complete before gametogenesis begins in both types. Thus, it is possible to describe two modes of development and tapetal structure, one parietal and one invasive, although the tapetum remains as a general secretory type in both cases. Thus, according to present work, the terms invasive and parietal are indicators of states of the secretory tapetum. strehliana structure Sul Brazil microtechniques. microtechniques micro techniques. techniques micro-techniques prophase others number protoplasts types Thus cases work

Resumo A literatura científica sobre anomalias em anfíbios é vasta, mas casos registrados de heterocromia ocular em anfíbios estão quase ausentes, mesmo considerando registros anedóticos. No território brasileiro, apenas dois casos de heterocromia ocular foram registrados anteriormente para anfíbios, ambos para anuros, o primeiro para a Mata Atlântica do nordeste do Brasil e o segundo para a região amazônica do norte do Brasil. No presente relato, descrevemos dois casos de heterocromia ocular no hilídeo Boana albomarginata, ambos no bioma Mata Atlântica, estado da Bahia, nordeste do Brasil, representando o primeiro registro de heterocromia ocular para esta espécie e o terceiro caso registrado para uma espécie de anfíbio no Brasil. Um olho de cada exemplar observado apresentava atipicamente íris de cor azul chamativa e homogênea, preenchendo toda sua superfície ou apenas a metade inferior, representando casos de heterocromia completa e setorial, respectivamente. Além disso, a não-usual íris azul só esteve detectável sob a luz do dia, quando a cor de fundo da íris era branca. À noite, a cor de fundo padrão da íris cobreada ou dourada permaneceu inalterada e a cor azul não pôde ser detectada. Nenhuma outra anomalia detectável ou comportamento incomum foi observada para ambos os exemplares. Este é o primeiro relato de heterocromia ocular em anfíbios representado por uma cor azul bem-marcada e limitada a um padrão diurno de cor da íris. Mais estudos são necessários para determinar a natureza desta anomalia e suas potenciais consequências para o indivíduo e para a espécie. vasta ausentes anedóticos brasileiro anuros albomarginata Bahia homogênea inferior setorial respectivamente disso nãousual usual dia branca noite detectada exemplares bemmarcada bem marcada
Abstract The scientific literature on amphibian anomalies is large, but registered cases of amphibians’ ocular heterochromia are almost absent, even considering anecdotal records. In the Brazilian territory, only two cases of ocular heterochromia were formerly registered for amphibians, both for anurans, the first from the Atlantic Forest of northeastern Brazil and the second from the Amazonian region of northern Brazil. In the present account, we report two cases of ocular heterochromia in the hylid treefrog Boana albomarginata, both from the Atlantic Forest biome, Bahia state, northeastern Brazil, representing the first record of ocular heterochromia for this species and the third case registered for an amphibian’s species in Brazil. One eye of each observed specimen had an unusually flashy and homogeneous blue-colored iris, filling its entire surface or only its lower half, representing cases of complete and sectoral heterochromia, respectively. Furthermore, the unusual flashy blue iris was only detectable during daylight, when the iris background color was white. At night, the standard copper to golden iris background color remains unchanged, and the blue color cannot be detected. No other detectable anomalies or unusual behaviors were observed for both specimens. This is the first report of amphibian ocular heterochromia represented by a flashy blue color iris and limited to a daylight iris color pattern. Further studies are necessary to determine the nature of this anomaly and its potential consequences for the specimen and the species. large amphibians absent records territory anurans account albomarginata biome state s bluecolored colored half respectively Furthermore white night unchanged detected specimens pattern

Abstract The objective of this study was to analyze the influence of insertion torque, bone type, and peri-implant bone loss on implant stability quotient (ISQ) of cylindrical external hexagon (EH) and Morse Taper (MT) implants. Forty-four single implants were placed in the edentulous areas of 20 patients who met the inclusion and exclusion criteria. Immediately after implant placement (t1) and after osseointegration (four and six months for mandible and maxilla, respectively) (t2), insertion torque, resonance frequency, and peri-implant bone loss were measured using probing depths and digital periapical radiography. A significant difference was noted in the ISQ values between t1 and t2 in type III bone for EH and MT implants. No significant difference in bone loss values was observed when comparing bone types for EH or MT in all evaluated sites. Based on marginal bone loss assessed using radiography, there was no significant difference between the MT and EH groups. A positive correlation between torque and ISQ t1 value was observed for MT (correlation: 0.439; p = 0.041) and EH (correlation: 0.461; p = 0.031) implants. For EH and MT implants, the greater the insertion torque, the greater was the ISQ value (moderately positive correlation). A weak negative correlation was found between bone type and ISQ t1 for MT implants. Contrarily, no correlation was observed between bone type and ISQ t1 for EH implants. In all cases, bone loss around the implants was clinically normal. periimplant peri (ISQ (EH (MT Fortyfour Forty four 2 criteria t (t1 maxilla respectively t2, , (t2) frequency radiography sites groups (correlation 0.439 0439 0 439 0.041 0041 041 0.461 0461 461 0.031 0031 031 moderately correlation. . correlation) Contrarily cases normal (t (t2 0.43 043 43 0.04 004 04 0.46 046 46 0.03 003 03 0.4 4 0.0 00 0.

Abstract This study aimed to evaluate volumetric polymerization shrinkage, degree of conversion and Vickers hardness of four bulk-fill resin composites light-activated with their dedicated light curing units (LCUs). Four groups were evaluated, according to the type of composite and curing mode: Tetric EvoCeram Bulk-fill (TEBO) and Tetric EvoFlow Bulk-fill (TEBF) were light-activated with Bluephase Style 20i (20s, in high-mode), while Tetric Powerfill (TEPO) and Tetric Powerflow (TEPF) were light-activated with Bluephase PowerCure (3s). Volumetric polymerization shrinkage test (n = 6) was performed in standardized box-shaped class-I cavities of extracted third molars (4 x 4 x 4 mm). Teeth were scanned before and after resin composite application by micro-computed tomography, and acquired data were evaluated with Amira software. Degree of conversion (n = 5) was evaluated at the top and bottom surfaces of composite cylindric samples (4 mm diameter, 4 mm thickness) using an FT-IR spectrometer (spectra between 1,500 and 1,800 cm-1, 40 scans at a resolution of 4 cm-1). Three Vickers indentations (50 g / 15 s), spaced 500 μm apart, were performed on the top and bottom composite surfaces and averaged. One-way ANOVA was used for data evaluation. TEPF showed the lowest volumetric polymerization shrinkage (p < 0.05), while the other composites were not significantly different within each other (p > 0.05). All materials presented a significant decrease in degree of conversion and Vickers hardness when compared top to bottom surfaces (p < 0.05). Bottom to top surface ratios for degree of conversion ranged from 0.8 (TEBO and TEPO) to 0.9 (TEBF and TEPF), and from 0.4 (TEPO) to 0.7 (TEBF and TEPF) for hardness. In conclusion, resinous materials present a decrease in hardness and degree of conversion from top to bottom even when a higher power is used, while the flowable material TEPF showed the lowest volumetric shrinkage values compared to the other materials. bulkfill bulk fill lightactivated activated LCUs.

ABSTRACT Serra da Saudade Formation corresponds to the upper part of the stratigraphic column of the Bambuí Group. Few studies have addressed the soil properties and pedogenesis of the pelitic rocks rich in potassium minerals of this formation. This study analyzed siltstone-derived soils, some of which are glauconitic (green siltstone; “verdete”), to understand the role of the main pedogenetic factors and processes in the landscape of the Central-West region of the Minas Gerais State, covered by Cerrado vegetation. Nine soil profiles were described, and their morphological, physical, chemical and mineralogical properties were analyzed. Soils were classified as Neossolos Litólicos (P1, P3, P6, P8 and P9), Cambissolos Háplicos (P2 and P5), Argissolo Vermelho-Amarelo (P4) and Argissolo Acinzentado (P7). The main active pedogenetic processes identified in the study area are melanization, goethization, argiluviation and elutriation. These are essentially controlled by the nature of the parent material and position of the soil in the relief. Soils are typically shallow, dystrophic, highly Al-saturated and contain essentially quartz and micas in the coarse fractions (sand and silt) and illite/glauconite and kaolinite in the clay fraction. In soil environments with siltstone and green siltstone under “dry forests”, the soil water pH was higher and high levels of exchangeable calcium and magnesium, a eutrophic character and high-activity clay were observed. Barium, chromium, lead and zinc contents were high in all studied soils. Green siltstone-derived soils have peculiar physical and chemical properties, divergent from those developed from other glauconitic rocks on the Earth surface. However, greenish tones in horizons are common in all these soils.

ABSTRACT Background: Vectorial transmission through hematophagous triatomine insects remains the primary mode of Chagas Disease contagion. These insects have become increasingly common in urban environments. Therefore, this study aimed to report an encounter of triatomines with trypanosomatid infection in a vertical residential condominium in Rio Branco, the capital of the state of Acre, in the western Brazilian Amazon. Methods: Triatomines were collected from residents and sent to the municipality's Entomological Surveillance sector. Trypanosomatid positivity was evaluated using optical microscopy, followed by species and genotype identification using molecular biology techniques. Results: Twenty-five adult triatomine specimens were collected from two of three condominium buildings invading apartments from the 2nd to 13th floors. Six specimens were identified as Rhodnius sp. and 19 as R. montenegrensis. Among these, molecular tests were conducted on seven specimens, with five testing positive for Trypanosoma cruzi, all belonging to genotype TcI. Conclusions: These findings underscore the need for further studies to better understand the invasive capacity of these insects in these environments and the mechanisms involved in this process.

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. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.
