Phosphate species can affect aquatic ecosystems, as excess of this nutrient can cause eutrophication, generating environmental impacts. Lamellar double hydroxides have shown promise in removing phosphate at low concentrations (10-50 mg L 1). In this context, lamellar double hydroxides were synthesized interspersed with nitrates and humic substances, searching for a new product that favors phosphorus adsorption. X-ray diffraction showed the presence of characteristic peaks of lamellar double hydroxides and thermogravimetric analysis showed the decomposition behavior of lamellar structure. The adsorption capacity occurred quickly (< 30 min), being more efficient for lamellar double hydroxides with NO3. The maximum adsorption capacity showed results of 35.03 and 44.20 mg g 1 for lamellar double hydroxides with humic substances and lamellar double hydroxides with NO3, respectively. The complexation capacity showed that pH directly influences complexation, being greater for lamellar double hydroxides with humic substances at pH 6.5. Thus, nanostructured materials with humic substances are promising for use in contaminant remediation and adsorption can be a fast and efficient technique for use in soil and water. ecosystems eutrophication impacts 1050 10 50 (10-5 1. . 1) context Xray X ray structure < ( 3 min, min , min) NO3 NO 3503 35 03 35.0 4420 44 20 44.2 respectively 65 6 5 6.5 Thus water 105 (10- 350 0 35. 442 4 2 44. 6.

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 Natural products have been studied as potential anthelmintic drugs. This study aimed to evaluate the effects of the polypeptides/proteins exuded from Mimosa caesalpiniifolia mature seeds on the model nematode Caenorhabditis elegans. After seed immersion for 24 h at 25 ºC in sodium phosphate buffer, pH 7.0, containing 0.15 M NaCl and 1.0 M MgSO4, the constituent polypeptides/proteins were fractionated using ammonium sulfate precipitation followed by ultrafiltration and their effects on C. elegans motility were assessed. Moreover, we evaluated by Atomic Force Microscopy (AFM) whether exposition of the nematode to the polypeptide fraction McSEX10-2 could cause any alteration on the animal’s external surface (cuticle). The whole seed exudates (SEX) from the M. caesalpiniifolia mature seeds (named McSEX) and its polypeptide/protein derived fractions, termed McSEX90%/80°C, McSEX30-10, and McSEX10-2, inhibited the C. elegans motility with an IC50 of 15.18, 12.59, 9.74 and 1.34 μg mL-1.The McSEX10-2 fraction, which encompassed the polypeptides with the molecular mass varying from 10 kDa to 2 kDa, was the most effective. In addition, McSEX10-2 altered the ultrastructure and the mechanical properties of the C. elegans cuticle. McSEX10-2, in particular, can be used as a model to bioinspire structure-based design of new peptides that could control, alone or in combination with other drugs, economically important parasitic nematodes. drugs polypeptidesproteins proteins buffer 70 7 0 7.0 015 15 0.1 1 1.

Resumo Fundamento Não existem estudos randomizados comparando a manutenção do ritmo sinusal após ablação por cateter (AC) em relação ao tratamento com fármacos antiarrítmicos (AA) em pacientes idosos portadores fibrilação atrial (FA) paroxística. Objetivos Comparar os resultados clínicos do isolamento das veias pulmonares (VPs) com o cateter PVAC Gold de segunda geração com o uso de AA em idosos com FA paroxística sintomática, recorrente, apesar do uso de fármacos AA. Métodos Sessenta pacientes com FA paroxística ≥ 65 anos e sem cardiopatias estruturais foram randomizados para duas formas de tratamento: grupo 1: AC e grupo 2: AA. O desfecho primário foi a taxa livre de recorrência de FA após pelo menos um ano de seguimento. Os desfechos secundários foram: progressão para formas persistentes de FA, impacto na qualidade de vida (QVFA) e complicações. O nível de significância adotado na análise estatística foi de 5% (p<0,05). Resultados A taxa livre de recorrência de FA foi de 80% (10% com amiodarona) no grupo AC, após 1,3 procedimentos por paciente e de 65% no grupo AA (60% com amiodarona), (p = 0,119) num seguimento médio de 719 dias (Q1: 566; Q3: 730). A taxa livre de FA persistente foi de 83,4% no grupo AC e de 67,7% no grupo AA (p = 0,073). Ambas as estratégias apresentaram melhora no escore de QVFA durante o seguimento (p < 0,001), sem diferença entre os grupos. Embora sem repercussão clínica ou impacto no teste de avaliação intelectual, 25% dos pacientes do grupo PVAC apresentou sinais de embolização cerebral na RNM cerebral. Conclusões Ambas as estratégias para manutenção do ritmo sinusal promoveram melhora na qualidade de vida de pacientes idosos com FA sintomática, sem diferença estatística nos desfechos clínicos preconizados. Estudos adicionais usando tecnologias com melhor perfil de segurança são necessários para avaliar os benefícios da AC em pacientes idosos com FA.

Abstract Background There are no randomized studies comparing the maintenance of sinus rhythm after catheter ablation (CA) concerning treatment with antiarrhythmic drugs (AA) in elderly patients with paroxysmal atrial fibrillation (AF). Objectives To compare the clinical results of pulmonary vein (PV) isolation with the second-generation PVAC Gold catheter against AA treatment in elderly people with recurrent symptomatic paroxysmal AF, refractory to at least one AA, and without structural heart disease. Methods Sixty patients with paroxysmal AF ≥ 65 years old were randomized to two forms of treatment: group 1: CA and group 2: AA drugs. The primary outcome was the AF recurrence-free rate after at least one year of follow-up. Secondary outcomes were: progression to persistent forms of AF, impact on quality of life (QOLF), and complications. The significance level adopted in the statistical analysis was 5% (p<0.05). Results The AF recurrence-free rate was 80% (10% with amiodarone) in the CA group, after 1.3 procedures per patient and 65% in the AA group (60% with amiodarone), (p = 0.119) in an average follow-up of 719 days (Q1: 566; Q3: 730). The persistent AF free rate was 83.4% in the AC group and 67.7% in the AA group (p = 0.073) Both strategies showed an improvement in the AFQoL score during follow-up (p < 0.001), with no difference between the groups. Although without clinical repercussions or impact on the intellectual assessment test, 25% of patients in the CA group showed signs of cerebral embolization on brain MRI. Conclusions Both strategies for maintaining sinus rhythm promoted an improvement in the quality of life of elderly patients with symptomatic AF, with no statistical difference in the clinical outcomes. Additional studies using technologies with a better safety profile are needed to evaluate the benefits of CA in elderly patients with AF. (CA (AA .

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.

RESUMO As tangerineiras e seus híbridos são acometidos por doenças economicamente importantes. Merece destaque a mancha marrom de Alternaria (Alternaria alternata f. sp. citri), por estar presente em todas as áreas de produção de tangerinas. Esse trabalho objetivou determinar o efeito de óleos essenciais sobre A. alternata f. sp. citri. Os experimentos foram conduzidos no Laboratório de Fitopatologia, e no laboratório de Biologia e Tecnologia Pós-Colheita da Universidade Federal da Paraíba, Areia, PB. Foram utilizados três isolados do patógeno, e dez óleos essenciais de sementes de uva, girassol, eucalipto, gengibre, copaíba, menta, ervadoce, citronela, cravo e linhaça na concentração de 1%, diluídos em meio de cultura batata-dextrose-ágar, para os testes in vitro. Para o teste nos frutos os óleos foram diluídos em água destilada e os frutos imersos nos tratamentos por 5 min. Além do fungicida Tiabendazol (400 mL/100L) e água destilada estéril consistiram nas testemunhas. Os frutos foram inoculados com suspensão de conídios do patógeno (105 conídios/mL). Avaliou-se o índice de velocidade de crescimento micelial, diâmetro de colônia, produção e dimensões de esporos, severidade da doença em frutos e atividade enzimática.

ABSTRACT Tangerines and their hybrids are affected by economically essential diseases. The Alternaria brown spot (Alternaria alternata f. sp. citri) deserves to be highlighted, as it is present in all tangerine production areas. This study aimed to determine the effect of essential oils on A. alternata f. sp. citri. The experiments were carried out in the Laboratories of Phytopathology and Biology and Technology of Post-Harvest of the Federal University of Paraíba, Areia, PB. Three pathogen isolates were used, and ten essential oils from grape, sunflower, eucalyptus, ginger, copaiba, mint, fennel, citronella, clove, and linseed at a concentration of 1%, diluted in potato dextrose agar for in vitro tests. The oils were diluted in distilled water for the fruit test, and the fruits were immersed in the treatments for 5 min. In addition, the fungicide Thiabendazole (400 mL/100L) and sterile distilled water were used as the control treatments. The fruits were inoculated with a conidia suspension of the pathogen (105 conidia/mL). Mycelial Growth Rate Index, colony diameter, spore production and dimensions, fruit disease severity, and enzymatic activity were evaluated. A completely randomized design was used, with 12 treatments and four replications in vivo. The results indicate that the essential oils of mint, eucalyptus, fennel, and citronella were efficient in the in vitro control of the pathogen, ultimately inhibiting the growth of fungal colonies. Eucalyptus oil efficiently managed A. alternata f. sp. citri on ‘Dancy’ tangerine fruits. Essential oils did not influence the enzymatic activity of the fruits. diseases f sp highlighted areas PostHarvest Post Harvest Paraíba Areia PB grape sunflower eucalyptus ginger copaiba mint fennel clove 1 1% tests test min addition 400 (40 mL/100L mL100L mLL mL 100L L 105 (10 conidia/mL. conidiamL conidia/mL . conidia/mL) Index diameter dimensions severity evaluated vivo colonies ‘Dancy Dancy 40 (4 10 (1 4 (

Resumo Objetivo Pesquisa e identificação de Cutibacterium acnes (C. acnes) e de outros microrganismos em amostras de tecidos profundos coletados em cirurgias limpas de ombro em pacientes que não foram submetidos a nenhum procedimento invasivo articular prévio e que não possuíam antecedentes clínicos de infecção. Métodos Foram analisados os resultados das culturas de amostras de tecidos profundos intraoperatórias de 84 pacientes submetidos à cirurgia limpa primária do ombro. Foram utilizados tubos contendo meio de cultivo para armazenamento e transporte de agentes anaeróbicos, tempo prolongado de incubação e espectrômetro de massa para diagnósticos de agentes bacterianos. Resultados Foi evidenciado o crescimento de bactérias em 34 pacientes (40,4%) dos 84 incluídos no estudo. Desses, 23 apresentavam crescimento de C. acnes em pelo menos uma amostra de tecido profundo coletada, correspondendo a 27,3% do total de pacientes. O segundo agente mais encontrado foi o Staphylococcus epidermidis, presente em 7,2% do total de indivíduos incluídos. Evidenciamos maior relação da positividade de amostras com o gênero masculino, uma média de idade inferior, a ausência de diabetes mellitus, o escore ASA I e a profilaxia antibiótica na indução anestésica com cefuroxima. Conclusões Verificou-se um elevado percentual de isolados de diferentes bactérias em amostras de tecidos de ombros de pacientes submetidos a cirurgias limpas e primárias e sem histórico de infecção anterior.

Abstract Objective Research and identification of Cutibacterium acnes (C. acnes) and other microorganisms in deeptissue samples collected in clean shoulder surgeries of patients who did not undergo any previous invasive joint procedure and who had no clinical history of infection. Methods We analyzed the results of cultures of intraoperative deep tissue samples from 84 patients submitted to primary clean shoulder surgery. Tubes containing culture medium were used for storage and transport of anaerobic agents, prolonged incubation time, and mass spectrometer for diagnosis of bacterial agents. Results Bacteria growth was evidenced in 34 patients (40.4%) of the 84 included in the study. Of these, 23 had growth of C. acnes in at least one sample of deep tissue collected, corresponding to 27.3% of the total patients. The second most common agent was Staphylococcus epidermidis, present in 7.2% of the total individuals included. We showed a higher relationship between sample positivity and males, a lower mean age, absence of diabetes mellitus, ASA I score, and antibiotic prophylaxis in anesthetic induction with cefuroxime. Conclusions A high percentage of isolates of different bacteria was found in shoulder tissue samples of patients undergoing clean and primary surgeries, who had no history of previous infection. Identification of C. acnes was high (27.6%), and Staphylococcus epidermidis was the second most frequent agent (7.2%).

Abstract The present study aimed to evaluate the influence of increasing levels of corn straw replacement of sorghum silage on average daily gain, loin eye area, subcutaneous fat thickness, weight of commercial cuts, leg tissue composition, and physico-chemical characteristics of the meat from F1 Santa Inês × Dorper lambs maintained in a feedlot system. Treatments consisted of 0, 33, 66 and 100% corn straw replacement of sorghum silage. There were thirty-six 150-day-old male lambs. Corn straw replacement of sorghum silage in lamb feed reduced the average daily gain and weight of the ribs, besides promoting a quadratic influence on leg fat content. However, there was no influence on commercial carcass cuts, leg muscle index, leg tissue composition, and physico-chemical characteristics of the meat. Thus, corn straw can be used as alternative feedstuff for sheep rations to improve the production of high-quality sheep meat in semi-arid regions. area thickness cuts composition physicochemical physico chemical F system 0 33 6 100 thirtysix thirty six 150dayold dayold 150 day old ribs content However index Thus highquality high quality semiarid semi arid regions 3 10 15 1

RESUMO: Neoplasias mamárias caninas com componentes mesenquimais malignos, como carcinossarcomas e sarcomas, são um grupo de neoplasias pouco frequentes e histologicamente heterogêneas e pouco se sabe sobre o comportamento biológico das variantes histogênicas. O objetivo desse estudo é comparar as características anatomopatológicas e a expressão imunoistoquímica de COX-2 de diferentes subtipos histológicos de carcinossarcomas e sarcomas. Foram estudados 23 carcinosarcomas e 17 sarcomas da glândula mamária de cadelas. Os prontuários médicos foram revisados para obtenção de dados clínicos. Posteriormente, as lâminas histológicas foram avaliadas para acessar os subtipos mesenquimais, necrose, invasão vascular, grau histológico, metástase linfonodal. A imunoistoquímica foi realizada para avaliar a expressão de COX-2. Os tipos encontrados de proliferação mesenquimal maligna foram osteossarcoma (23/40), fibrossarcoma (7/40), lipossarcoma (6/40) e condrossarcoma (4/40). A diferenciação osteossarcomatosa foi predominante entre os sarcomas e carcinossarcomas e foi associado com invasão vascular (P=0,006) e metástase linfonodal (P=0,014). Uma expressão alta de COX-2 foi detectada em 14,3% dos carcinossarcomas (células carcinomatosas e/ou sarcomatosas) e 27,3% dos sarcomas. Os carcinossarcomas e sarcomas apresentaram características clínicas e patológicas semelhantes e se desenvolveram como tumores grandes, com necrose intratumoral e predomínio de alto grau histológico, mas com baixa frequência de invasão vascular e metástase distante. Os subtipos osteossarcomatosos apresentaram características mais agressivas quando comparados com subtipos não osteossarcomatosos.

ABSTRACT: Canine mammary neoplasms with malignant mesenchymal components, such as carcinosarcomas and sarcomas, belong to an uncommon and histologically heterogeneous group. Little is known about the biological behavior of these histogenic variants. This study aimed to compare the clinicopathological characteristics and the COX-2 immunohistochemical expression of different histologic subtypes of carcinosarcomas and sarcomas. Samples of 23 carcinosarcomas and 15 sarcomas from the mammary glands of female dogs were studied. Medical records were reviewed to obtain clinical data. Subsequently, histology microscope slides were analyzed to assess for mesenchymal subtypes, necrosis, vascular invasion, histologic grades, and lymph node metastasis. Immunohistochemistry was used to assess the COX-2 expression. The malignant mesenchymal proliferation was categorized into osteosarcomas (23/40), fibrosarcomas (5/40), liposarcomas (6/40) and chondrosarcomas (4/40). The osteosarcomatous differentiation was the most predominant type among the sarcomas and carcinosarcomas and was associated with vascular invasion (P=0.010) and lymph node metastases (P=0.014). High COX-2 expression was detected in 14.3% of the carcinosarcomas (carcinoma and/or sarcoma cells) and 27.3% of the sarcomas. The carcinosarcomas and sarcomas had similar clinical and pathological characteristics and developed as large tumors, with intratumoral necrosis and a predominance of high histologic grades, although the frequency of vascular invasion and lymph node metastasis was low. Osteosarcoma subtypes presented more aggressive characteristics than non-osteosarcoma subtypes.

This investigation describes the synthesis of eugenol analogs presenting 1,2,3-triazole fragments and evaluation of their antileishmanial activity. The alkylation of guaiacol (1) with allyl bromide afforded 1-(allyloxy)-2-methoxybenzene (2) (93% yield). The Claisen rearrangement conducted with 1 gave ortho eugenol (3) (82% yield). Alkylation procedures performed with 3 produced 1-allyl-3-methoxy-2-(prop-2-yn-1-yloxy)benzene (4) (73% yield) and 1-allyl-3-methoxy-2-(pent-4-yn-1-yloxy)benzene (6) (53% yield). The copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) reactions involving alkynes 4 and 6 with different benzylic azides afforded twenty-two eugenol analogs with 1,2,3-triazole functionalities (48-93% yield). We screened the compounds at 10 μmol L 1 against Leishmania braziliensis intracellular amastigotes during macrophage infection. The action of these compounds was compared with the known leishmanicidal drug amphotericin B. None of the analogs were toxic to macrophages at 10 μmol L-1. The cytotoxic concentration at 50% (CC50), effective concentration at 50% (EC50), and selectivity index (SI) were determined to the best compounds 4-((2-allyl-6-methoxy)phenoxymethyl)-1-(4-chlorobenzyl)-1 H-1,2,3-triazole (8c) and 4-((2-allyl-6-methoxy)phenoxymethyl)-1-(4-trifluoromethoxybenzyl)-1 H-1,2,3-triazole (8h). They showed a significant leishmanicidal effect, with EC50 of 28.09 µmol L-1 (8c) and 52.03 µmol L-1 (8h). The SIs were 9.7 for 8c and > 5.7 for 8h. These compounds have the potential as new leishmanicidal agents against L. braziliensis and may represent a starting point for the development of alternative treatments for cutaneous leishmaniasis. 1,2,3triazole 123triazole triazole 1,2,3 2 activity (1 1allyloxy2methoxybenzene allyloxymethoxybenzene allyloxy methoxybenzene (2 93% 93 (93 yield. yield .

Polymers are options as antimicrobials for skin protection, antifouling surfaces, and fabrics. Here we analyzed the interaction of polymers based on poly(methacrylate) (PMMA) and poly((dimethylamino ethyl) methacrylate) (PDMAEMA) with model membranes and bacteria. We used the homopolymers PMMA, PDMAEMA, and the diblock copolymer(s) prepared with different PMMAm:PDMAEMAn ratios (m/n). The interactions of PDMAEMA and PMMAm-b-PDMAEMAn with large unilamellar vesicles (LUVs) prepared with phosphatidylcholine and phosphatidylglycerol at different pHs, were analyzed by nuclear magnetic resonance (NMR), dynamic light scattering, and zeta potential. These polymers promoted LUVs leakage of a fluorescent probe (5,6-carboxyfluorescein) localized exclusively in the internal aqueous compartment. Interestingly, all copolymers exhibit a bell-shaped pH dependence for the polymer-induced LUVs leakage. The interaction of the positively charged polymers and the pH effect was also demonstrated using giant unilamellar vesicles. These copolymers inhibited bacterial growth in the micromolar range and can be used to prevent bacterial growth on surfaces. protection surfaces fabrics polymethacrylate poly methacrylate poly(methacrylate PMMA (PMMA polydimethylamino dimethylamino ethyl (PDMAEMA bacteria copolymer s copolymer(s PMMAmPDMAEMAn PMMAm PDMAEMAn m/n. mn m/n . m n (m/n) PMMAmbPDMAEMAn b (LUVs pHs NMR, NMR , (NMR) scattering potential 5,6carboxyfluorescein 56carboxyfluorescein carboxyfluorescein 5,6 5 6 (5,6-carboxyfluorescein compartment Interestingly bellshaped bell shaped polymerinduced polymer induced (m/n (NMR 6carboxyfluorescein 56 5,
