In recent years, the field of coordination chemistry has experienced a surge in interest regarding the synthesis and characterization of coordination complexes for diverse applications. This study is dedicated to investigating coordination compounds resulting from the interaction of nonsteroidal anti-inflammatory drugs (NSAIDs) with metal ions. The study research places significant emphasis on understanding the stability and thermal behavior of these coordination compounds. The utilization of thermoanalytical techniques is crucial in achieving this goal. Thermal analysis and thermokinetics provide valuable insights into the underlying mechanisms, kinetics, and energetics of these reactions, thereby facilitating the optimization of synthesis procedures. The research employs concurrent techniques, namely thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), to explore the thermal stability and decomposition pathways of these coordination compounds. Thermokinetic models and optimization methodologies are subsequently applied to identify key reaction parameters. The primary aim of this research is to unveil the thermal behavior, stability, and reaction kinetics of aceclofenac coordination compounds, thus contributing significantly to the understanding of thermokinetics and thermal analysis in the domain of coordination chemistry. Specifically, this study is focused on aceclofenac coordination complexes involving lanthanum and gadolinium, with the ultimate goal of advancing the field of coordination chemistry. years applications antiinflammatory anti inflammatory NSAIDs (NSAIDs ions mechanisms reactions procedures TG (TG DSC, DSC , (DSC) parameters Specifically gadolinium (DSC

The history of the discovery, use, and development of dyes is closely linked to the history of humanity itself. Among the first records of human civilization are cave paintings made from, e.g., fruits, plants, minerals, and insects. Over the centuries, using different techniques, colors have been given to all types of materials and products, from clothing to food. The chemicals responsible for colors are dyes - a vast collection of molecules of the most varied compositions, but which have in common the absorption of light within the visible window of the electromagnetic spectrum. This article aims not only to review the properties of some classes of natural dyes, their origins, and their applications but also to describe the various computational chemistry methods involved in designing new bio-inspired molecules. discovery use itself eg e g e.g. fruits plants minerals insects centuries techniques products food compositions spectrum origins bioinspired bio inspired e.g

ABSTRACT Potassium is a nutrient with the potential to increase plant tolerance to salt stress. The aim of this study was to evaluate the production and quality of kale subjected to salt stress and potassium concentrations in a protected environment. The experimental design was in split plots, with plots composed of five nutrient solutions (control treatment, S1 - standard nutrient solution prepared in low-salinity water, 0.5 dS m-1 (500 mg L-1 of KNO3), and four nutrient solutions prepared in brackish waters (3.5 dS m-1) containing four concentrations of KNO3 (S2 - 500 mg L-1, S3 - 625 mg L-1, S4 - 750 mg L-1, S5 - 1,000 mg L-1), and subplots represented by two leaf kale cultivars (Manteiga and Manteiga da Geórgia). Leaf production variables and post-harvest physical and chemical qualities were evaluated. The saline nutrient solution with the addition of NaCl (S2) reduced production but did not reduce the post-harvest quality of kale. The extra addition of KNO3 at 25% (S3) was efficient in reducing the deleterious effects of salt stress on the variables leaf length, leaf area, leaf production, and number of bunches. The cv.

RESUMO O potássio é um nutriente com potencial para aumentar a tolerância das plantas ao estresse salino. O objetivo deste estudo foi avaliar a produção e a qualidade da couve submetida ao estresse salino e às concentrações de potássio em ambiente protegido. O delineamento experimental adotado foi em parcela subdivididas, sendo as parcelas compostas por cinco soluções nutritivas (tratamento controle, S1 - solução nutritiva padrão usando água de baixa salinidade, 0,5 dS m-1 (500 mg L-1 de KNO3), e quatro soluções nutritivas preparadas em águas salobras (3,5 dS m-1) contendo quatro concentrações de KNO3 (S2 - 500 mg L-1, S3 - 625 mg L-1, S4 - 750 mg L-1, S5 - 1.000 mg L-1). As subparcelas foram representadas por duas cultivares de couve folha (Manteiga e Manteiga da Geórgia). Foram avaliadas as variáveis de produção de folhas e qualidades físicas e químicas pós-colheita. A solução nutritiva salinizada com adição de NaCl (S2) reduziu a produção, mas não reduziu a qualidade pós-colheita da couve folha. A adição extra de KNO3 em 25% (S3) foi eficiente para reduzir o efeito deletério do estresse salino sobre as variáveis comprimento de folha, área foliar, produção e número de maços. A cv.

Resumen Introducción: A partir del Boston Carpal Tunnel Questionnaire, se desarrolló una escala corta de 6 ítems llamada Six-Item Carpal Tunnel Symptoms Scale (CTS-6). Objetivo: Evaluar la CTS-6 para detectar pacientes con neuropatía periférica del nervio mediano con criterio quirúrgico. Materiales y Métodos: Se realizó un estudio descriptivo prospectivo observacional en un grupo de pacientes con diagnóstico clínico de síndrome del túnel carpiano. Se utilizó la CTS-6, y se corroboró el diagnóstico mediante electromiografía. Posteriormente, los pacientes fueron operados. Se analizaron las diferencias en el puntaje de la CTS-6 entre los distintos niveles de gravedad determinados por electromiografía. Resultados: Se analizaron 106 pacientes. El 20,75% tenía síndrome del túnel carpiano bilateral. Se evaluaron 126 manos. La mediana del puntaje de la CTS-6 fue de 21 (mín. 16,5; máx. 26). Según los resultados de la electromiografía, el 24,22% de los casos de síndrome del túnel carpiano eran graves. Al comparar el puntaje de la CTS-6 según la gravedad del síndrome del túnel carpiano evaluada por electromiografía, la mediana del puntaje de la CTS-6 fue de 16,5 en los casos leves, de 21 en los casos moderados y de 26 en los casos graves. Conclusiones: El puntaje de la CTS-6 fue mayor en los pacientes con síndrome del túnel carpiano grave según la electromiografía. Esto plantea la hipótesis de que podría ser útil como herramienta diagnóstica no invasiva en el síndrome del túnel carpiano para definir pacientes que se beneficien con el tratamiento quirúrgico.

Abstract Introduction: The Six-Item Carpal Tunnel Symptoms Scale (CTS-6) is a a short 6-item scale based on the Boston Carpal Tunnel Questionnaire (BCTQ). Objective: To evaluate the CTS-6 to identify patients with peripheral neuropathy of the median nerve using surgical criteria. Materials and Methods: A prospective descriptive observational study was conducted on a group of patients diagnosed with carpal tunnel syndrome. The CTS-6 was employed, and the diagnosis was confirmed with electromyography. The patients then underwent surgery. The differences in the CTS-6 score between the various severity levels measured by electromyography were examined. Results: 106 patients were analyzed and a total of 126 hands were evaluated. 20.75% had bilateral carpal tunnel syndrome. The median CTS-6 score was 21 (min. 16.5; max. 26). According to electromyography results, 24.22% of CTS cases were severe. When comparing the CTS-6 score according to the severity of carpal tunnel syndrome assessed by electromyography, the median CTS-6 score was 16.5 in mild cases, 21 in moderate cases, and 26 in severe cases. Conclusions: Electromyography revealed a higher CTS-6 score in patients with severe carpal tunnel syndrome. This raises the possibility that it could be used as a noninvasive diagnostic tool in carpal tunnel syndrome to determine which patients would benefit from surgical therapy.

Abstract This case report presents a rare manifestation of a pigmented cutaneous metastasis of breast carcinoma with a zosteriform distribution. A 77-year-old woman, previously diagnosed with invasive ductal carcinoma of the breast, exhibited pigmented lesions resembling shingles on the left thoracodorsal region. Dermoscopic and histopathological examinations confirmed invasive carcinoma of mammary origin associated with melanocytic colonization. The zosteriform pattern, though rare, has been reported in cases of cutaneous metastasis from breast cancer. Treatment options include addressing the primary tumor and direct approaches such as surgery or radiotherapy for skin lesions. This report highlights the importance of clinical suspicion, histopathological evaluation, and immunohistochemical examinations for accurate diagnosis, enabling timely and appropriate treatment for improved patient outcomes.

Resumo Este relato de caso apresenta uma manifestação rara de metástase cutânea pigmentada de câncer de mama com distribuição zosteriforme. Uma mulher de 77 anos, previamente diagnosticada com carcinoma ductal invasivo de mama, apresentava lesões pigmentadas semelhantes a herpes-zóster na região toracodorsal esquerda. Os exames dermatoscópico e histopatológico confirmaram carcinoma invasivo de origem mamária associado à colonização melanocítica. O padrão zosteriforme, embora raro, já foi relatado em casos de metástases cutâneas de câncer de mama. As opções de tratamento incluem abordar o tumor primário e abordagens diretas, como cirurgia ou radioterapia para lesões cutâneas. Este relatório destaca a importância da suspeita clínica, avaliação histopatológica e exames imuno-histoquímicos para um diagnóstico preciso, permitindo um tratamento oportuno e apropriado para melhores resultados dos pacientes.

ABSTRACT The use of biostimulants may mitigate the deleterious effects of salt stress on plant growth and physiological variables. Thus, the present study aimed to evaluate the growth, physiology, organic solutes, and visual characteristics of two tropical ornamental species (Celosia argentea and Catharanthus roseus) cultivated with brackish waters and treated with Ascophyllum nodosum extract. The experiment was performed in greenhouse conditions. The experimental design was a complete randomized block arranged in a split-plot scheme. The plots comprised three levels of electrical conductivity of the irrigation water (ECw - 0.5, 2.5, and 4.5 dS m-1), the subplots four concentrations of algae extract (0, 400, 800, and 1200 mg L-1), and the sub-subplots two tropical ornamental herbaceous species [C. argentea and C. roseus]. The salinity of the irrigation water negatively affects the morphological and physiological characteristics of the two species studied, mainly C. roseus. Irrigation with water up to 2.5 dS m-1 favored visual quality and increased the purchasing preference for C. argentea. The use of intermediate concentrations (400 mg L-1) of algae extract (A. nodosum) promoted partial mitigation of the effects of salt stress on biomass production and leaf gas exchange, especially for C. argentea, but these positive responses decreased or disappeared with the intensification of salt stress and the increase in algae extract concentration. variables Thus physiology solutes Celosia roseus conditions splitplot split plot scheme ECw 05 0 5 0.5 25 2 45 4 4. m1, m1 m 1 , m-1) 0, (0 400 800 120 L1, L1 L subsubplots sub C [C . roseus] studied 2. m- (40 L-1 A.

RESUMO O uso de bioestimulantes pode mitigar os efeitos deletérios do estresse salino no crescimento e variáveis fisiológicos. Assim, objetivou-se com o presente estudo avaliar o crescimento, fisiologia, solutos orgânicos e características visuais de duas espécies ornamentais tropicais (Celosia argentea and Catharanthus roseus) cultivadas utilizando-se águas salobras e tratadas com extrato de Ascophyllum nodosum. O experimento foi conduzido em casa de vegetação, em delineamento experimental em blocos ao acaso, dispostos em parcelas subsubdivididas, sendo as parcelas constituídas por três níveis de condutividade elétrica da água de irrigação (CEa - 0,5, 2,5 e 4,5 dS m-1), as subparcelas quatro concentrações de extrato de algas (0, 400, 800 e 1200 mg L-1) e as subsubparcelas de duas espécies herbáceas ornamentais tropicais: C. argentea e C. roseus. A salinidade da água de irrigação afeta negativamente as características morfológicas e fisiológicas das duas espécies estudadas, principalmente C. roseus. A irrigação com água de até 2,5 dS m-1 favoreceu a qualidade visual e aumentou a preferência de compra por C. argentea. O uso de concentrações intermediárias (400 mg L-1) de extrato de alga (A. nodosum) promoveu mitigação parcial dos efeitos do estresse salino na produção de biomassa e nas trocas gasosas foliares, especialmente para C. argentea, mas essas respostas positivas diminuíram ou desapareceram com a intensificação do estresse salino e com o aumento da concentração do extrato de algas. fisiológicos Assim objetivouse objetivou se fisiologia Celosia roseus utilizandose utilizando nodosum vegetação acaso subsubdivididas CEa 05 0 5 0,5 25 2 2, 45 4 4, m1, m1 m 1 , m-1) 0, (0 400 80 120 L1 L L-1 C estudadas m- (40 A.

ABSTRACT The energy efficiency of irrigation systems is an aspect of great importance in all design and management processes; For this reason, an investigation was carried out in the "Tío Pedro" farm located in the municipality of Venezuela, Ciego de Ávila province during the years 2021 and 2022 with the objective of estimating the general energy yield in the furrow irrigation system. During this period, the pump unit offers the following average operating regime: pump flow rate of 61.1 L s-1; pumping time of 2,8 hours and pumping head of 18.2 m. This behavior reduces a hydraulic power of 10.9 kW and a pump efficiency of 85.2%. The energy supplied in pumping was 429.4 kWh and the energy absorbed in the evaluated period was 631.9 kWh. In relation to the energy parameters of the system, an energy balance of the supply of 7,4 m was obtained; a system energy load index of 15.2 m; an energy efficiency of the pumping of 68.2% (excellent) and a general energy efficiency of the system of 34.0% (normal).

Abstract This study investigated consumers' perceptions of adding bee pollen to bread. An attitude questionnaire composed of 48 statements related to "general health," "light products," "natural products," "salty products," "food as a reward," "pleasure," and "food neophobia" was answered by the participants, who indicated their level of agreement with each statement according to a 5-point Likert scale, ranging from (1) "totally disagree" to (5) "totally agree." A check-all-that-apply (CATA) questionnaire was also employed to characterize 12 visual stimuli. The creation of stimuli was carried out using a factorial design, resulting in 12 images of bread. Three clusters of consumers were identified, each associating positive attributes with stimuli containing bee pollen, regardless of the health claim, while negative attributes were associated with stimuli without added pollen. The main positive drivers of liking were "I would buy," "attractive," "pleasant color," "healthy," "light," and "natural." On the other hand, the negative drivers of liking were "unattractive," "I don't like it," "I wouldn't buy," "hard," and "unpleasant color." This study provides valuable information for developing healthier bread using natural ingredients with bioactive compounds, such as bee pollen.

Abstract Papaya is a climacteric fruit, rapidly ripening after harvesting due to ethylene production and increased respiratory rate. This swift ripening results in softening of fruit tissues, shortening the fruit shelf life. Pre-cooling serves as an alternative to minimize fruit ripening and post-harvest losses by reducing metabolism. This study aimed to evaluate the effect of pre-cooling on the quality and conservation of Formosa 'Tainung I' papaya. Papayas at maturation stage II were obtained from a commercial orchard with conventional production. The experimental design was a completely randomized 4×6 split-plot scheme, with pre-cooling treatments (Control, without pre-cooling treatment; pre-cooling at 15 °C in a cold chamber; pre-cooling at 7 °C in a cold chamber; and forced-air cooling at 7 °C) in the plot, and days of storage (0, 7, 14, 21, 28, and 35 days) in the subplot. Pre-cooling effectively delayed the ripening and senescence of Formosa papaya, reducing the loss of green color and firmness. Regardless of the treatment used, chilling injury and incidence of fungi from the genus Fusarium and Alternaria limited the shelf life of Formosa 'Tainung I' papaya up to 21 days of storage. Additionally, the appearance of hardened regions in the pulp compromised the sensory quality of the fruits, necessitating further investigation into the causes of this disorder. rate tissues Precooling Pre postharvest post harvest metabolism precooling pre Tainung I 46 4 6 4× splitplot split plot scheme Control, Control (Control 1 C chamber forcedair forced air 0, 0 (0 14 28 3 subplot firmness used 2 Additionally fruits disorder (

Resumo O mamão é uma fruta climatérica, amadurecendo rapidamente após a colheita devido à produção de etileno e aumento da taxa respiratória. Esse amadurecimento rápido resulta no amolecimento dos tecidos da fruta, reduzindo a vida útil. O pré-resfriamento serve como uma alternativa para minimizar o amadurecimento da fruta e as perdas pós-colheita, reduzindo o metabolismo. Este estudo teve como objetivo avaliar o efeito do pré-resfriamento na qualidade e conservação do mamão 'Tainung I' Formosa. Mamões no estágio de maturação II foram obtidos de um pomar comercial com produção convencional. O design experimental foi um esquema de parcelas divididas completamente aleatório 4×6, com tratamentos de pré-resfriamento (Controle, sem tratamento de pré-resfriamento; pré-resfriamento a 15 °C em uma câmara fria; pré-resfriamento a 7 °C em uma câmara fria; e resfriamento por ar forçado a 7 °C) na parcela, e dias de armazenamento (0, 7, 14, 21, 28 e 35 dias) na subparcela. O pré-resfriamento retardou efetivamente o amadurecimento e a senescência do mamão Formosa, reduzindo a perda de cor verde e firmeza. Independentemente do tratamento utilizado, lesões por frio e incidência de fungos do gênero Fusarium e Alternaria limitaram a vida útil do mamão 'Tainung I' Formosa até 21 dias de armazenamento. Além disso, o surgimento de regiões endurecidas na polpa comprometeu a qualidade sensorial das frutas, exigindo investigação adicional sobre as causas desse distúrbio. climatérica respiratória préresfriamento pré póscolheita, póscolheita pós colheita, pós-colheita metabolismo Tainung I convencional 46 4 6 4×6 Controle, Controle (Controle 1 C fria parcela 0, 0 (0 14 2 3 subparcela firmeza utilizado disso frutas distúrbio 4× (

Abstract The objective of this work was characterizing persimmons of the 'Giombo' and 'Rama Forte' cultivars harvested at different ripening stages in the Brazilian semiarid. Fruits were harvested at three ripening stages – green, semi-ripe and ripe – then evaluated for the following characteristics: fruit weight and diameter, skin and pulp color, fruit firmness, pulp pH, soluble solids content, titratable acidity, SSC/TA ratio, total soluble sugars, reducing sugars, astringency index, and the contents of tannin, vitamin C, carotenoid, β-carotene, and total extractable polyphenols. Also, total antioxidant activity by the DPPH and ABTS methods and pectin methylesterase, and polygalacturonase enzyme activities were evaluated. Two experiments were carried out in a completely randomized design, one for each cultivar, with treatments consisting of different stages of maturation, with five replications of three fruits each. Data were submitted to analysis of variance and the differences between the means were compared using the Tukey test at 5% probability. Fruit firmness and soluble solids content did not vary between maturation stages for any of the cultivars. However, the skin color index increased with advancing maturation for both 'Giombo' and 'Rama Forte'. The astringency index, the content of total extractable polyphenols, soluble tannins and the antioxidant capacity were lower in fruits harvested at the ripe stage, for both cultivars. It can be concluded that persimmons of the 'Giombo' and 'Rama Forte' cultivars present better physicochemical quality characteristics when harvested when ripe, with a totally yellow skin.

Resumo O objetivo deste trabalho foi caracterizar caquis das variedades ‘Giombo’ e ‘Rama Forte’ colhidos em diferentes estádios de maturação, produzidos na região nordeste do Brasil. Os frutos foram colhidos em três estádios de maturação; verde, semimaduro e maduro, e avaliados quanto as seguintes características: diâmetro do fruto, massa fresca, cor da casca e da polpa, firmeza do fruto, pH, acidez titulável, sólidos solúveis, relação sólidos solúveis/acidez, açúcares totais, açúcares redutores, índice de adstringência, teor de taninos solúveis, vitamina C, carotenoides, betacaroteno, polifenóis extraíveis totais, atividade antioxidante total (AAT) pelo método do DPPH e ABTS e atividade das enzimas pectina metil esterase (PME) e poligalacturonase (PG). Foram montados dois experimentos em delineamento inteiramente casualizado, um para cada variedade, sendo os tratamentos constituídos pelos diferentes estádios de maturação. A firmeza do fruto e o teor de sólidos solúveis não variaram entre os estádios de maturação para nenhuma das variedades. No entanto, o índice de cor da casca incrementou com o avanço da maturação tanto para ‘Giombo’ quanto para ‘Rama Forte’. O índice de adstringência, o conteúdo de polifenóis extraíveis totais, taninos solúveis e a capacidade antioxidante foram menores nos frutos colhidos no estádio maduro, para ambas as variedades. Pode-se concluir que caquis das variedades ‘Giombo’ e ‘Rama Forte’ apresentam melhores características físico-químicas de qualidade quando colhidos maduros, com casca totalmente amarelada. ‘Giombo Giombo Rama Forte Brasil verde maduro fresca polpa pH titulável solúveisacidez solúveis/acidez totais redutores adstringência C carotenoides betacaroteno AAT (AAT PME (PME PG.

Abstract Formed during marine regression periods, shelf valleys (SVs) are preterit river flows on the exposed continental shelf. This study investigates the influence of tectonic activity on forming these important morphological features. This research combines bathymetric, magnetometry, and seismic data to analyze the role of tectonic events in SV genesis and positioning. The bathymetric dataset provides information on SV locations and geometries along the continental shelf, whereas the 2D seismic sections illustrate that SVs formed above post-rift faults that reached Quaternary deposits. Aeromagnetic data indicates that the shallow and deep structures of the basement and sedimentary column-controlled SV locations and evolution. The multi-data integration demonstrates a strong correlation between neotectonic structures and SV location and geometries from the inner shelf (−25 m) to the shelf break (−55 m). The analysis of the 2D seismic data indicated that high-angle faults, formed under a strike-slip tectonic regime, primarily affected the Middle Miocene deposits beneath the shelf valleys. The formation of “negative flower pattern structures” was identified as a primary structural mechanism that contributed to SV formation. Reactivation events that occurred from the Late Cretaceous onwards, gave rise to these faults, which control SV formation and the capture of preterit drainage on the exposed continental shelf. The SV geometries display straight patterns and abrupt changes in direction (90°) due to the interplay of the NE-SW and NW-SE aligned faults. The results reinforce the importance of considering tectonic activity in the formation and evolution of shelf valleys. periods (SVs features magnetometry positioning D postrift post rift columncontrolled column controlled multidata multi −25 25 (−2 m −55 55 (−5 m. . highangle high angle strikeslip strike slip regime negative onwards 90° 90 (90° NESW NE SW NWSE NW SE −2 2 (− −5 5 9 (90 − ( (9

A new phenylpropanoid derivative, named euploic acid (1), was isolated from Euploca procumbens (Mill.) Diane & Hilger, Boraginaceae, along with lithospermic acid B (2), lithospermic acid (3), 9’’-methyl lithospermate (4), and luteolin-7-O-glucoside (5). Compound structures were determined by mass spectrometry (MS), nuclear magnetic resonance (NMR) analysis and comparison with published data. Absolute configuration of 1 was established via electronic circular dichroism (ECD). Anti-inflammatory potential of euploic acid (1) was assessed by measuring its inhibition of cytokine and nitric oxide production in stimulated J774 macrophages. Compound 1 significantly reduced pro-inflammatory mediator production and release by stimulated macrophages at non-cytotoxic concentrations, comparable to the efficacy of dexamethasone. Our findings demonstrate the potential of euploic acid (1) as an effective anti-inflammatory agent. This study contributes to the structural elucidation of a new phenylpropanoid derivative and highlights its promising anti-inflammatory activity in the treatment of inflammatory disorders. 1, , Mill.

Short-chain chiral esters are important constituents in natural fruit flavors, as well as in food and pharmaceutical industries. Different chemical and bio-catalytic routes are used for their synthesis, but the use of simultaneous techniques has not been much explored, as combinatorial synthesis and bio-catalysis in continuous-flow systems. Here, the objective was to synthesize chiral esters typically found in fruit flavors, to obtain chemical libraries with high conversion and enantiomeric excess, using combinations of these three techniques. Combinatorial synthesis in continuous-flow coil-type reactors with fix bed was used in the esterification of the secondary alcohols 2-butanol (1a), 2-pentanol (1b), 3-hexanol (1c), 2-heptanol (1d) and 2-octanol (1e) with acetic (2) and propanoic (3) acids. A surface-response method was applied to optimize the reaction conditions. Conversions were above 88% after 60 min for the reaction with chemical catalysts in continuous-flow reactors compared to 85%, but after 120 min, when conventional batch processes were used. By applying a biocatalyst, a chemical library of R acetates was prepared, with conversions over 48% after 48 h for batch and 40% after only 70 min for continuous flow reactions. It was observed that both enzymatic and homogeneous chemical catalysis showed to be viable for the chiral esters.

Abstract A checklist of recent and fossil fishes of the Order Characiformes is presented herein and believed to be complete through 2022. A total of 47 collaborators checked and provided information about their taxa of expertise. The list is arranged in alphabetical order by family and then genus and includes all available synonyms. From a total of 3,087 species group names and 527 genus group names, 2,334 species are currently treated as valid, and assigned to 301 genera and 24 families. This total includes 25 species known only from the fossil record, of which 21 are assigned to eight extant families and four are Incertae sedis in Characiformes, but does not include five species based on fossil which were wrongly treated in Characiformes. The status of 79 nominal species remains unresolved. When there are two competing hypotheses about the validity of a name, one of them is chosen and the alternate interpretation is provided in the remark section of that name. Distributional summaries are presented as numbers that correspond to areas for which there is a record of occurrence of the species. A list of unavailable names is provided at the end since some of those names may need additional research to certify their status. 2022 4 expertise synonyms 3087 3 087 3,08 52 2334 2 334 2,33 valid 30 7 unresolved name 202 308 08 3,0 5 233 33 2,3 20 0 3, 23 2,
