Anabolic steroids are often consumed by both amateur and professional sports practitioners with the aim of improving their performance and for the rapid gain of muscle mass. Nandrolone is one of the main steroids consumed and is, frequently, acquired illegally or from dubious sources, and this raises serious concerns regarding the quality of the products. This work sought to qualitatively and quantitatively evaluates oily, nandrolone-based anabolic steroids confiscated by the Federal Police Department, in the triple border (Paraguay-Brazil-Argentina, PY-BR-AR). For the quantitative study, we conducted a methodological validation analysis based on the application of solvent extraction and GC-MS (gas chromatography-mass spectrometry). A total of 40 samples of nandrolone steroids (as described on the label) were thoroughly investigated. The results obtained showed that 90% of the samples analyzed contained the active ingredient but 67.5% of these samples exhibited concentrations below the values indicated on the label; these products are thus considered to be of low quality and their consumption may pose serious risks to the consumers. The findings of this study point to the importance of enforcing regulatory controls on the sale of anabolic steroids with a view to inhibiting the consumption of counterfeit drugs that can pose serious risks to the health of consumers. mass frequently sources oily nandrolonebased Department ParaguayBrazilArgentina, ParaguayBrazilArgentina Paraguay Brazil Argentina, Argentina (Paraguay-Brazil-Argentina PYBRAR.

Resumo Toxoplasma gondii e Neospora caninum são dois protozoários intimamente relacionados que infectam uma ampla gama de animais, incluindo-se aves. Entretanto, a ocorrência de N. caninum e T. gondii em aves marinhas é desconhecida. Portanto, este estudo objetivou determinar a presença de DNA de T. gondii e N. caninum em amostras de tecidos, coletadas de 47 aves marinhas. Amostras de tecidos dos músculos peitorais, coração e cérebro foram coletadas de 47 aves marinhas mortas ao longo da costa do estado de Santa Catarina, SC, Brasil. O DNA foi extraído dos tecidos e testado, usando-se a reação em cadeia da polimerase nested (nPCR), tendo em vista o espaçador interno transcrito 1 (ITS1). O DNA de T. gondii foi detectado em tecidos de sete aves marinhas (7/47, 14,8%), como gaivota (Larus dominicanus) (5/21) e bobo-pequeno (Puffinus puffinus) (2/8). O DNA de N. caninum foi detectado em tecidos de nove aves marinhas (9/47, 19,1%); gaivota (L. dominicanus) (4/21), bobo-pequeno (P. puffinus) (2/8), corvo-marinho (Phalacrocorax brasilianus) 1/4), atobá-pardo (Sula leucogaster) (1/5), e pardela-preta (Procellaria aequinoctialis) (1/1). No entanto, não foi observada coinfecção. Em conclusão, este estudo demonstrou a circulação de N. caninum e T. gondii em aves marinhas ao longo da costa de Santa Catarina, Brasil.

Abstract Toxoplasma gondii and Neospora caninum are two closely related protozoans that infect a wide range of animals, including birds. However, the occurrence of N. caninum and T. gondii in seabirds is unknown. Therefore, this study aimed to determine the presence of T. gondii and N. caninum DNA in tissue samples of seabirds. Tissue samples of the pectoral muscles, heart, and brain were collected from 47 birds along the coastline of Santa Catarina State, SC, Brazil. The DNA was extracted from the tissues and screened using nested-PCR (nPCR) targeting internal transcribed spacer 1 (ITS1). T. gondii DNA was detected in tissues from seven seabirds (7/47, 14.8%), kelp gull (Larus dominicanus) (5/21), and Manx shearwater (Puffinus puffinus) (2/8). N. caninum DNA was detected in tissues of nine seabirds (9/47, 19.1%), the kelp gull (L. dominicanus) (4/21), Manx shearwater (P. puffinus) (2/8), neotropic cormorant (Phalacrocorax brasilianus) (1/4), brown booby (Sula leucogaster) (1/5), and white-chinned petrel (Procellaria aequinoctialis) (1/1); however, no co-infection was observed. In conclusion, this study showed the circulation of N. caninum and T. gondii in seabirds along the coastline of Santa Catarina State. Further studies are required to clarify the role of these birds in the epidemiology of neosporosis and toxoplasmosis. animals However N T unknown Therefore muscles heart 4 State SC Brazil nestedPCR nested PCR nPCR (nPCR ITS1.

The graphene oxide (GO)-silver nanoparticles (AgNPs) hybrid material (GO-AgNPs) has garnered significant interest due to its ability to combine the unique properties of GO and AgNPs, showing promise applications in biomedicine, nanocomposites, biosensors, and antimicrobial materials. However, further investigation is needed to understand the nanobio-interactions and toxicity of GO-AgNPs nanohybrid. Assessing the toxicity of GO-AgNPs on red blood cells (hemolysis) and its interactions with blood biomolecules (biocorona formation) is mandatory for biomedical applications and safety evaluation of this material. In this work, we investigate the biocorona formation associated with GO-AgNPs after interaction with human plasma and hemolysate biomolecules linked to its hemolytic effects. Both GO and GO-AgNPs exhibited a dose-dependent hemolytic effect, with GO-AgNPs showing three times greater hemolysis than GO. Nonetheless, biocorona formation fully mitigated the hemolytic effect of both materials, however, morphological damages in red blood cells may occur yet. Our findings show that biocorona formation dramatically changes the surface chemistry, colloidal behavior and toxicity of this hybrid material. Finally, this work contributes to understanding how graphene-silver nanoparticles interact with blood components to design strategies to minimize toxicity risks and enhance their applications in biomedicine and nanobiotechnology.

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 O manejo nutricional pode ser uma estratégia eficiente para mitigar os efeitos da salinidade na produção e qualidade de frutos. O objetivo deste trabalho foi avaliar a produção e qualidade de frutos de mini melancia, cultivar Sugar Baby, cultivado em ambiente protegido, sob estresse salino e relações K+/Ca2+. O estudo foi realizado em casa de vegetação, em delineamento de blocos casualizados, em esquema 1 + 5, resultando em seis tratamentos e quatro repetições. Foram aplicadas seis soluções nutritivas, uma utilizando água de baixa salinidade (0,5 dS m-1) e solução nutritiva padrão (S1, tratamento controle) e as demais utilizando água salinizada com NaCl, a 5,0 dS m-1 (S2) e adição extra de K (S3 = 50% e S4 = 100%) e Ca (S5 = 50% e S6 = 100%). Foram avaliadas as variáveis de produção (produção de frutos, diâmetro longitudinal do fruto, diâmetro transversal do fruto, espessura da casca, firmeza da polpa) e qualidade pós-colheita (sólidos solúveis, vitamina C, acidez titulável e índice de maturação), além das variáveis referentes a cor da polpa (luminosidade, croma e ângulo de Hue). A adição de NaCl reduziu a produção de frutos, diâmetro longitudinal dos frutos, diâmetro transversal dos frutos, espessura da casca e vitamina C. Entre as soluções nutritivas salinas, a adição extra de K a 50% (S3) atenua os efeitos deletérios do estresse salino nas variáveis de produção e o teor de vitamina C. Sob estresse salino, a adição extra de K em 50% (S3) e Ca em 100% (S6) intensifica a coloração vermelha da polpa. melancia Baby protegido KCa2 KCa Ca2 K+/Ca2+ vegetação casualizados 5 repetições 0,5 05 0 (0, m1 m S1, S1 S (S1 controle 50 m- S2 (S2 S3 (S 100 S5 100%. . fruto póscolheita pós colheita sólidos solúveis C maturação, maturação , maturação) luminosidade, luminosidade (luminosidade Hue.

ABSTRACT Nutritional management can be an efficient strategy to mitigate the effects of salinity on fruit production and quality. This study aimed to evaluate the production and quality of fruits of mini watermelon crop, Sugar Baby cultivar, grown in a protected environment, under salt stress and K+/Ca2+ ratios. The study was carried out in a greenhouse, using a randomized block design, 1 + 5 scheme, resulting in six treatments and four replications. Six nutrient solutions were employed, one using low-salinity water, with NaCl (0.5 dS m-1) and standard nutrient solution (S1, control treatment), and the others using salinized water at 5.0 dS m-1 (S2) and extra addition of K (S3 = 50% and S4 = 100%) and Ca (S5 = 50% and S6 = 100%). The production (fruit production, longitudinal and transverse diameter of fruit, rind thickness, pulp firmness) and postharvest quality (soluble solids, vitamin C, titratable acidity, and maturation index), in addition to the variables related to the color of the pulp (lightness, chroma index, and Hue angle) were evaluated. The addition of NaCl reduced fruit production, longitudinal, and transverse diameter of fruit, rind thickness, and vitamin C content. Among saline nutrient solutions, extra addition of 50% K (S3) attenuates the deleterious effects of salt stress on the production variables and vitamin C content. Under salt stress, extra addition of 50% K (S3) and 100% Ca (S6) intensifies the red color of the pulp. crop cultivar environment KCa2 KCa Ca2 K+/Ca2 ratios greenhouse design scheme replications employed lowsalinity low 0.5 05 0 (0. m1 m S1, S1 S (S1 treatment, treatment , treatment) 50 5. m- S2 (S2 S3 (S 100 S5 100%. . thickness firmness soluble solids acidity index index) lightness, lightness (lightness angle evaluated content (S6 K+/Ca 0.

Abstract Objectives Evidence suggests that ketamine’s influence on brain-derived neurotrophic factor (BDNF) might be involved in its mechanism of rapid antidepressant action. We aimed to evaluate the differential impact of ketamine and esketamine on serum BDNF levels and its association with response patterns in treatment-resistant depression (TRD). Methods Participants (n = 53) are from a randomized, double-blind clinical trial comparing the efficacy of single-dose ketamine (0.5mg/kg, n = 27) and esketamine (0.25mg/kg, n = 26) in TRD. Depression severity was assessed before and 24 hours, 72 hours, and 7 days after the intervention, using the Montgomery-Åsberg Depression Rating Scale (MADRS). Blood samples were collected before infusion, 24 hours, and 7 days afterwards. Results There were no significant changes in BDNF levels at post-infusion evaluation points, and no difference in BDNF levels comparing ketamine and esketamine. Both drugs exhibited similar therapeutic effect. There was no association between BDNF levels and response to treatment or severity of depressive symptoms. Conclusion There was no significant treatment impact on BDNF serum levels – neither with ketamine nor esketamine – despite therapeutic response. These results suggest that ketamine or esketamine intervention for TRD has no impact on BDNF levels measured at 24 hours and 7 days after the infusion.

Thermo-responsive copolymers grafted with N-isopropylacrylamide (NIPAm) are excellent candidates for drug release. Dextran sulfate (DS) acts as a specific ligand in inflamed regions, turning it highly useful as a target for drug delivery. DS was associated with NIPAm to produce amphiphilic graft copolymers prepared via free radicals. The molar ratio of feed reagents NIPAm/DS varied from 1 (DS-g-PNIPAm) to 4 (DS-g-4PNIPAm). The synthesis was confirmed by spectroscopic techniques (Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR)). All copolymers showed self-organization capacity in an aqueous medium in temperatures higher than 34 °C, and sizes less than 300 nm. DS-g-3PNIPAm exhibited stability in water and in phosphate buffer at pH 7.4. Scanning electron microscopy confirmed their spherical shape. This copolymer showed specificity to leukemic cells, and normal cells’ proliferation. Methotrexate (MTX) is a very low water-soluble drug used for rheumatoid arthritis and cancer. Unfortunately, MTX have severe collateral effects. MTX-loaded nanoparticles can overcome such issues as well as enhance bioactivity and stability. The MTX was encapsulated and delivered from the DS-g-3PNIPAm with potential target delivery due to the presence of DS. Comparison with MTX encapsulated in other nanoparticles reveals that the DS-g-PNIPam presents the best performance among the thermo-responsive and the second among the target MTX nanocarriers.

Abstract Industrial egg residue (IER) possesses substantial concentrations of calcium and crude protein. The objective of this study was to measure the digestibility and performance of broilers when IER was added to the feed. Four treatments were tested, which caused increasing replacement of calcitic limestone by IER (0, 35, 70 and 100%) during a 42-day production cycle. First, total bird excreta were collected from broilers with and without IER, and we determined dry matter digestibility, apparent metabolizable energy (AME), calcium, and nitrogen retention. The IER presented 7.5% of crude protein, 31% of calcium, 209 kcal/kg of AME and the digestibility coefficients for dry matter, crude protein, and calcium were calculated at 83.95%, 86.20%, and 67%, respectively. After the digestibility test, the effects of IER on performance, carcass and meat yield were evaluated. No significant differences between the treatments were found in terms of performance (weight gain, feed conversion, consumption, and mortality), and no differences were found in terms of carcass or meat yield. A linear decrease in the percentage of abdominal fat was observed with increasing inclusion of IER in feed. These findings suggest that IER can totally replace limestone (calcium carbonate) in broiler diets.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

ABSTRACT Background: Sexually Transmitted Infections (STIs) can be caused by viruses, bacteria, and parasites. The World Health Organization estimated more than 300 million new global cases of curable STIs among individuals of reproductive age. Infection by Trichomonas vaginalis is one of the most prevalent curable STL Despite the current treatments available, the diagnosis of T. vaginalis can be difficult, and the resistance to the treatment increased concern for the healthcare system. Objectives: The aim of this study was to determine the prevalence and factors associated with Trichomonas vaginalis infection among women of reproductive age attending community-based services for cervical screening. Patients and methods: A total of 1477 reproductive-aged women attending 18 Primary Health Care Units in Botucatu, Brazil, from September to October 2012, were enrolled. A structured questionnaire was used for individual face-to-face interviews for obtaining data on sociodemographic, gynecologic, and obstetrics history, sexual and hygiene practices, among others. Cervicovaginal samples were obtained for detection of T. vaginalis by culture using Diamond's medium and microscopic vaginal microbiota classification according to Nugent. A multivariable logistic regression analysis was carried out to estimate Odds Ratios (OR) and 95% Confidence Intervals (95% CI) for the association between participants’ sociodemographic, behavioral factors, and clinical factors with T. vaginalis infection. Results: Median age of study participants was 33 years (ranging from 18 to 50). The overall prevalence of T. vaginalis infection was 1.3% (n = 20). Several factors were independently associated with T. vaginalis infection, such as self-reporting as black or Pardo for ethnicity (OR = 2.70; 95% CI 1.03–7.08), smoking (OR=3.18; 95% CI 1.23–8.24) and having bacterial vaginosis (OR = 4.01; 95%CI = 1.55–10.38) upon enrollment. A protective effect of higher educational level (having high school degree) was observed (OR = 0.16; 95% CI 0.05–0.53). Conclusions: Our data suggest that screening programs to correctly detect T. vaginalis infection can be helpful to guide prevention strategies to the community. Our study supports an association between abnormal vaginal microbiota and T. vaginalis infection.

ABSTRACT Seed microbiolization has been increasingly contributed to researches due to its beneficial action in the initial growth of seedlings and control of phytopathogens. Thus, the aim of this study was to evaluate the initial growth and control of fungi associated with cowpea seeds by the seed microbiolization with commercial strains of Trichoderma spp. Seeds of cowpea cultivar 'BRS Gurguéia' were analyzed in a completely randomized design, with four replications, using five commercial strains based on Trichoderma asperellum and T. harzianum (Trichodermax®, Quality®, Trichodermil®, Agroguard® and Ecotrich®) and two control treatments, represented by untreated seeds (negative control) and the fungicide carbendazim (positive control). Sanity, germination, emergence and electrical conductivity tests of seeds were carried out to confirm the hypotheses. Seed microbiolization with Trichoderma asperellum and Trichoderma harzianum are effective in reducing the incidence of fungi and have antimicrobial activity similar to synthetic fungicide. The strains T. asperellum T-211 (Trichodemax®), T. asperellum URM-5911 (Quality®) e T. harzianum ESALQ-1306 (Trichodermil®) promote increases for seed vigor. The percentage of seed emergence is maximized with the application of strains T. asperellum (Quality® and Trichodemax®). The commercial strains of Trichoderma tested increase the initial growth of cowpea seedlings cv. 'BRS Gurguéia'.

Abstract The animal feed science is in constant search for new products that bring economic return, without harming the quality of the final product. This study aimed to evaluate the effect of increasing levels of substitution of corn by biscuit bran in lamb diet upon the fatty acid profile of its meat and its physicochemical and sensory characteristics. Twenty-four male lambs divided in four treatments were used. The treatments consisted in increasing levels (0, 15, 30, and 45%) of substitution of corn by biscuit bran in lamb diet. The significance of the treatments was determined by ANOVA and the adjusted means were compared by Tukey test at 5%. The effects were determined by linear and quadratic responses. The use of up to 45% biscuit bran sweet type did not modify the physical and sensory characteristics of meat, just as it did not affect nutrient and dry matter intakes and animal performance. A replacement of 45%, reduces the cholesterol (P = 0.03) and the total content of saturated fatty acid (P = 0.002), not modifying other physicochemical characteristics. The replacement of corn by biscuit bran sweet type in the feeding represents an alternative nutritional strategy for sheep meat production with desirable organoleptic and quality characteristics. return product Twentyfour Twenty used 0, 0 (0 15 30 45 5 5% responses performance P 0.03 003 03 0.002, 0002 0.002 , 002 0.002) ( 1 3 4 0.0 00 000 0.00 0.

ABSTRACT The Atlantic Forest is made up of different vegetation types over extensive latitude. Most of its remnants are in mountain ranges, which are responsible for the maintenance of most endemic and threatened species in this domain. Here we present the floristic composition of the Área de Proteção Ambiental Mestre Álvaro (APAMA), a coastal massif at Espírito Santo State with expressive altitudinal amplitude (100-800 a.s.l.) containing remnants never floristically studied. Knowing the composition of this protected area is important because it includes an altitudinal range not yet evaluated in floristic comparisons involving highland and lowland forests between the latitudes 18-21° S. We found 493 species (in 292 genera and 91 families): ten are regional endemic species, nine are new records of occurrence for the state, and 52 are under some degree of threat of extinction. Our results indicate the presence of flora elements' typical of both highland and lowland forests, which makes the APAMA essential in a scenario extremely fragmented. Finally, our data provide an unprecedented floristic list for regional forest restoration projects, as well as an invaluable source of data for biogeographic studies that seek to understand the effect caused by neighboring vegetation types on the composition of lowland forests.

7a-Hydroxyroyleanone is a bioactive diterpene isolated from leaves of Tetradenia riparia, active against tuberculosis and T. cruzi. In order to use this compound as starting material for the synthesis of compounds with enhanced bioactivity we aimed the dehydration of the 7-alpha-hydroxyl group of royleanone. The reaction performed in acetic acid and hydrochloric acid under reflux gave an unexpected chlorinated naphtoquinone, with aromatization and opening of one of the rings of the starting material, as major product, besides 6,7-dehydroroyleanone and a complex mixture of other products. The reaction products were purified by high-speed countercurrent chromatography with hexane-acetonitrile 1:1. Compounds were tested for their anti-leishmanial activity (L. amazonensis) pointing out a potential leishmanicidal agent which may favor the development of more effective therapies.

Abstract Inflammatory dermatoses are prevalent worldwide, with impacts on the quality of life of patients and their families. The aim of this study was to determine the anti-inflammatory effects of Achyrocline satureioides oily extracts and nanocapsules on the skin using a mouse model of irritant contact dermatitis induced by croton oil, and a skin inflammation model induced by ultraviolet B (UVB) radiation. The mice were treated with 15 mg/ear oily extract (HG-OLAS) or nanocapsules (HG-NCAS) of A. satureioides incorporated into Carbopol® 940 hydrogels. We found that HG-OLAS and HG-NCAS formulations reduced ear edema in croton oil-induced lesions with maximum inhibitions of 54±7% and 74±3%, respectively. HG-OLAS and HG-NCAS formulations decreased ear edema induced by UVB radiation (0.5 J/cm2), with maximum inhibitions of 68±6% and 76±2% compared to the UVB radiation group, respectively. HG-OLAS and HG-NCAS modulated myeloperoxidase (MPO) activity after croton oil induction. Furthermore, croton oil and UVB radiation for 6 and 24 h, respectively, stimulated polymorphonuclear cells infiltration. The topical treatments reduced inflammatory processes, as shown by histological analysis. Together, the data suggest that topical application of A. satureioides oily extracts and nanocapsules produced antiedematogenic and anti-inflammatory effects. They constitute a compelling alternative for treatment of skin injuries.
