ABSTRACT Our objective was to evaluate the genetic potential of two maize populations derived from commercial hybrids for beginning a reciprocal recurrent selection (RRS) program. For this, 280 interpopulation half-sib (HS) progenies were produced from two populations (140 HS from each population), which were derived from the selfing of the commercial hybrids AS1598 (Pop1) and RB9210 (Pop2). We then evaluated the 280 HS progenies, the two base populations, and the two hybrids for grain yield (GY) and ear and plant architecture traits in southwestern Goias during the 2020 winter season. Variance components and genetic values of each progeny were estimated using the REML/BLUP (Restricted Maximum Likelihood/Best Linear Unbiased Prediction) methodology. Genetic gains by selection of the top 20% of progenies were predicted using two strategies: i) selection for GY and ii) selection for GY and days to silking (DTS) simultaneously. We observed genetic variability in both populations for all tested traits; therefore, it is possible to obtain genetic gains from the interpopulation improvement of both Pop1 and Pop2. The genetic gain estimates with the selection based on GY were 9.03 and 3.45% for Pop1 and Pop2, respectively. Simultaneous selection for GY and DTS resulted in positive (>4%) genetic gains for GY in both populations and decreased the cycle in Pop1, but we did not observe any alteration of the cycle in Pop2. We concluded that both populations derived from commercial hybrids have genetic potential for interpopulation improvement using RRS.

RESUMO O objetivo deste trabalho foi avaliar o potencial genético de duas populações de milho derivadas de híbridos comerciais para iniciar um programa de seleção recorrente recíproca (SRR). Para isso, 280 progênies de meios-irmãos (PMI) interpopulacionais foram obtidas de duas populações (140 PMI de cada população) derivadas da autofecundação dos híbridos comerciais AS1598 (Pop1) e RB9210 (Pop2). As 280 PMI, as duas populações e os dois híbridos foram avaliados para produtividade de grãos (PG) e seis caracteres de arquitetura de planta e de espiga em dois locais no Sudoeste de Goiás, na segunda safra de 2020. Os componentes de variância e os valores genéticos de cada progênie foram estimados pela metodologia REML/BLUP (Restricted Maximum Likelihood/Best Linear Unbiased Prediction). Os ganhos genéticos com a seleção de 20% das progênies superiores foram preditos usando duas estratégias: i) seleção truncada para PG e ii) seleção simultânea para PG e florescimento feminino (FF). Observou -se variabilidade genética nas duas populações para todos os caracteres avaliados. Consequentemente, é possível obter ganhos genéticos a partir do melhoramento interpopulacional das Pop1 e 2. As estimativas de ganhos com a seleção truncada para PG foram de 9,03% e 3,45% para as Pop1 e Pop2, respectivamente. A seleção simultânea para PG e FF resultou em ganhos positivos (>4%) para PG em ambas populações e redução no ciclo na Pop1, mas não houve alteração para ciclo na Pop2. Conclui-se que as duas populações derivadas de híbridos comerciais de milho têm potencial genético para o melhoramento interpopulacional com emprego de SRR. SRR .

The compound 2-hydrazinyl-4-(4-methoxyphenyl)thiazole (PD76) is a novel thiazolyl hydrazine derivative with proven antifungal activity against different fungal species, mainly Candida and Cryptococcus. Considering the advantages of oral route for clinical therapy, the aim of this work was to evaluate the potential intestinal permeability of this new antifungal drug. For the quantitation of PD76, a high-performance liquid chromatography method was developed and fully validated. The cytotoxicity of the compound in Caco-2 cells was analyzed and intestinal permeability of PD76 was assessed by means of the comparison of in vitro assay in Caco-2 cells and in silico platforms ADMETlab and admetSAR. Cell viability above 70% was obtained at all PD76 studied concentrations. Using Caco-2 cell model, the compound showed apparent permeability coefficients (Papp) of 5.25 × 10-6 and 23.28 × 10-6 cm s-1 in apical-basolateral and basolateral-apical directions, respectively. Experiments performed using verapamil as P-gp inhibitor demonstrated that PD76 is slightly susceptible to active efflux. Both in silico platforms inferred that PD76 presents permeability in Caco-2 cells, with Log P values of 2.82 (ADMETlab) and 2.10 (admetSAR). The results obtained in permeability studies showed that PD76 presents moderate intestinal permeability and a promising profile for clinical application. 2hydrazinyl44methoxyphenylthiazole hydrazinylmethoxyphenylthiazole 2 hydrazinyl 4 methoxyphenyl thiazole PD (PD76 species Cryptococcus therapy drug highperformance high performance validated Caco2 Caco Caco- PD7 admetSAR 70 concentrations model Papp (Papp 525 5 25 5.2 106 10 6 10- 2328 23 28 23.2 s1 s 1 s- apicalbasolateral apical basolateral basolateralapical directions respectively Pgp gp efflux 282 82 2.8 (ADMETlab 210 2.1 .

ABSTRACT In 2000, Cleide Costa published a paper presenting the state of knowledge of the Neotropical Coleopte ra, with a focus on the Brazilian fauna. Twenty-four years later, thanks to the development of the Coleoptera section of the Taxonomic Catalog of the Brazilian Fauna (CTFB - Catálogo Taxonômico da Fauna do Brasil) through the collaboration of 100 coleopterists from all over the globe, we can build on Costa’s work and present an updated overview of the state of knowledge of the beetles from Brazil. There are currently 35,699 species in 4,958 genera and 116 families known to occur in the country, including representatives of all extant suborders and superfamilies. Our data show that the Brazilian beetle fauna is the richest on the planet, concentrating 9% of the world species diversity, with some estimates accounting to up to 15% of the global total. The most diverse family in numbers of genera is Cerambycidae (1,056 genera), while in number of species it is Chrysomelidae (6,079 species). Conotrachelus Dejean, 1835 (Curculionidae) is the most species-rich genus, with 570 species. The French entomologist Maurice Pic is the author who has contributed the most to the naming of species recorded from Brazil, with 1,794 valid names in 36 families, whereas the Brazilians Ubirajara R. Martins and Maria Helena M. Galileo are the only ones among the top-ten authors to have named species in the 21st century. Currently, approximately 144 new species of Brazilian beetles are described each year, and this average is projected to increase in the next decade to 180 species per year, or about one new Brazilian beetle every two days. 2000 ra Twentyfour Twenty four later CTFB Brasil 10 globe Costas s Brazil 35699 35 699 35,69 4958 4 958 4,95 11 country superfamilies planet 9 diversity 15 total 1,056 1056 1 056 (1,05 genera, , genera) 6,079 6079 6 079 (6,07 . species) Dejean 183 Curculionidae (Curculionidae speciesrich rich genus 57 1794 794 1,79 3 R M topten top ten st century Currently 14 year 18 days 200 3569 69 35,6 495 95 4,9 1,05 105 05 (1,0 6,07 607 07 (6,0 5 179 79 1,7 20 356 35, 49 4, 1,0 0 (1, 6,0 60 (6, 17 7 1, 2 (1 6, (6 (

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.

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

ABSTRACT The high concentrations of salts present in the water sources of the Brazilian Northeastern semi-arid region stand out as one of the limiting factors for agricultural production, contributing to soil salinization and/or sodification. Thus, it is extremely important to identify strategies to mitigate the effects of salt stress on plants, such as the foliar application of salicylic acid. In this context, the objective of the present study was to evaluate the effect of foliar application of salicylic acid as an attenuator of salt stress on leaf gas exchange, water relations, photosynthetic pigments, and growth of okra cv. Canindé grown in a hydroponic system. The experiment was conducted in a greenhouse, in Pombal, PB, Brazil. The treatments consisted of four levels of electrical conductivity of the nutrient solution - ECns (3.0, 5.0, 7.0, and 9.0 dS m-1) and four concentrations of salicylic acid - SA (0, 1.2, 2.4, and 3.6 mM) distributed in a completely randomized design in a split-plot scheme, considering the ECns levels as the plots and SA concentrations as the subplots, with four replicates and two plants per plot. ECns from 3.0 dS m-1 inhibited the synthesis of photosynthetic pigments, leaf gas exchange, and growth of okra cv. Canindé. Foliar application of salicylic acid at concentrations of up to 3.6 mM does not alleviate the effects of salt stress on water relations, gas exchange and growth of okra. Salicylic acid at a concentration of 1.8 mM stimulates chlorophyll a and b biosynthesis in okra under ECns of 3.0 and 4.0 dS m-1, respectively. semiarid semi arid production andor or sodification Thus context relations pigments cv system greenhouse Pombal PB Brazil 3.0, 30 3 0 (3.0 50 5 5.0 70 7 7.0 90 9 9. m1 m 1 0, (0 12 2 1.2 24 4 2.4 36 6 3. splitplot split plot scheme subplots m- 18 8 1. 40 4. m1, 1, respectively (3. 5. 7.

RESUMO As altas concentrações de sais presentes nas águas no semiárido do Nordeste brasileiro destacam-se como um dos fatores limitantes para produção agrícola, contribuindo para a salinização e/ou sodificação dos solos. Assim, é de extrema importância a identificação de estratégias para amenizar os efeitos do estresse salino sobre as plantas, como a aplicação foliar de ácido salicílico. Neste sentido, objetivou-se com este estudo avaliar o efeito da aplicação foliar de ácido salicílico como atenuante do estresse salino nas trocas gasosas, relações hídricas, pigmentos fotossintéticos e crescimento do quiabeiro cv. Canindé cultivado em sistema hidropônico. O experimento foi desenvolvido em casa de vegetação, em Pombal, PB. Os tratamentos foram constituídos de quatro níveis de condutividade elétrica da solução nutritiva - CEsn (3,0; 5,0; 7,0 e 9,0 dS m-1) e quatro concentrações de ácido salicílico - AS (0; 1,2; 2,4 e 3,6 mM) distribuídos em delineamento inteiramente casualizado em esquema de parcelas subdivididas, sendo os níveis de CEsn considerados as parcelas e as concentrações de AS as subparcelas, com quatro repetições e duas plantas por parcela. CEsn a partir de 3,0 dS m-1 inibiu a síntese de pigmentos fotossintéticos, as trocas gasosas foliares e o crescimento do quiabeiro cv. Canindé. A aplicação foliar de ácido salicílico em concentração de até 3,6 mM não alivia os efeitos do estresse salino sobre as relações hídricas, trocas gasosas e crescimento do quiabeiro. Ácido salicílico com concentração de 1,8 mM estimula a biossíntese de clorofila a e b em quiabeiro sob CEsn de 3,0 e 4,0 dS m-1, respectivamente. destacamse destacam se agrícola eou ou solos Assim sentido objetivouse objetivou hídricas cv hidropônico vegetação Pombal PB 30 3 0 (3,0 5,0 50 5 70 7 7, 90 9 9, m1 m 1 (0 1,2 12 2 24 4 2, 36 6 3, subdivididas subparcelas parcela m- 18 8 1, 40 4, m1, respectivamente (3, 5, ( (3

Abstract Objective: To evaluate the conservative management of newborns born at ≥35 weeks of gestational age, at risk for early-onset neonatal sepsis (EOS). Methods: Retrospective, analytic cohort study (2016 to 2019), including newborns ≥35 weeks of gestational at risk of EOS, asymptomatic at birth, managed conservatively in full rooming-in: serial physical examination and clinical observation for at least 48 h. They were classified into three groups, according to the clinical course: asymptomatic (group A), symptomatic for other reasons (group B), and with sepsis (group C). Risk factors, clinical signs and differential diagnoses of sepsis, length of stay, and discharge conditions were evaluated. Results: The authors evaluated 769 asymptomatic newborns at risk of EOS. (mean birth weight 2999 ± 485 g and gestational age 37.6 ± 1.7 weeks, respectively) corresponding to 12.2% of rooming-in admissions. The most prevalent risk factors were colonization by Group B Streptococcus (29%), prolonged rupture membrane duration (21.9%) and preterm labor (21.4%). Most of all of them (53.9%) remained asymptomatic (group A). Group B corresponded for 45.3%, and the most common clinical signs were hypothermia (24.5%), tremors (8.7%) and vomiting (8%). Environmental dysthermia (50.7%), prematurity (20.0%), and feeding intolerance (15.7%) were common in Group B. Laboratory tests were performed in 3.5%. Five patients (one confirmed) comprised group C (0.8/1,000 live births). There were no deaths. The median length of stay was 64 h (IQR 50-93). Conclusion: The rate of clinical/confirmed EOS was low. Most of the symptomatic patients only needed clinical evaluation to rule out sepsis. Management was shown to be safe. Objective 35 ≥3 earlyonset early onset .

Chemically modified imidazole molecules: 4-(1H-imidazol-1-yl)aniline, 4-(1H-imidazol-1-yl)benzaldehyde, 4-(1H-imidazol-1-yl)phenol and (4-(1H-imidazol-1-yl)phenyl)methanol were investigated as inhibitors of the copper (Cu0) corrosion in 0.5 mol L-1 H2SO4 medium. The electrochemical corrosion data were obtained by monitoring open circuit potential, linear potentiodynamic polarization and electrochemical impedance spectroscopy techniques, while the computational density functional theory (DFT) method was applied to correlate the electronic properties of the molecules with corrosion inhibition efficiencies. All molecules had inhibited the Cu corrosion, and the inhibition values lied between 80 and 94%. A good correlation between the inhibition efficiencies values and Gibbs adsorption energy was found, showing that the more negative Gibbs energy, better interaction between the corrosion inhibitor with the Cu0 surface, diminishing its corrosion in 0.5 mol L-1 H2SO4 medium. The DFT calculations showed significative differences in electronic and reactivity properties of imidazole and other molecules. The higher corrosion inhibition of imidazole derivates could be explained by electrophilic characteristic of these molecules, since there are empty molecular orbitals spread over mainly in benzene rings that make a metal-ligand charge transfer, receiving electronic density from the copper surface by backbonding, according to the electronic Fukui functions and the potential charge distribution considering the map of electrostatic potential. 41Himidazol1ylaniline, 41Himidazol1ylaniline Himidazolylaniline 4 1H imidazol 1 yl aniline, aniline H 4-(1H-imidazol-1-yl)aniline 41Himidazol1ylbenzaldehyde, 41Himidazol1ylbenzaldehyde Himidazolylbenzaldehyde benzaldehyde, benzaldehyde 4-(1H-imidazol-1-yl)benzaldehyde 41Himidazol1ylphenol Himidazolylphenol phenol 41Himidazol1ylphenylmethanol Himidazolylphenylmethanol phenyl methanol (Cu0 05 0 5 0.

This study evaluated the pollutant levels (NO2, SO2, CO, and O3), air quality index (AQI) and the influence of meteorological variables and coronavirus disease (COVID-19) pandemic on the air quality in Rio de Janeiro. The data set used comprises periods before (March-April, 2019) and during pandemic (March-April, 2020). According to the AQI results, on most days, the air quality was ranked as “good”. Brazilian air quality standards for SO2, O3, and NO2 were not exceeded in any of the monitoring stations during partial lockdown, while CO exceeded in all periods in one site due to industrial emission. Comparing both periods, descriptive statistics for the meteorological parameters presented no differences, which suggests similar conditions. However, when evaluated week by week in 2020, weather conditions presented some differences that probably affected pollutant concentrations. The correlations between O3 and NO2 and some meteorological parameters indicate that variations in both favored ozone formation, since it is a photochemical process favored by temperature and solar radiation and that, in Rio de Janeiro, low NO2 concentrations lead to increased O3. The improvements on air quality during the partial lockdown may be attributed mainly to a reduction on emission sources rather than weather conditions.

RESUMO Aplicações exógenas de compostos químicos estimulam modificações no metabolismo vegetal e conferem tolerância a diferentes estresses ambientais, incluindo o déficit hídrico. Esta pesquisa teve como objetivo avaliar os efeitos do uso de ácido salicílico (AS) e prolina na redução do estresse hídrico em uma variedade tradicional de feijão-caupi em um clima típico do semiárido brasileiro. Foi utilizado um delineamento inteiramente casualizado em esquema fatorial 2 × 4 com cinco repetições. Foram utilizadas duas lâminas de irrigação, correspondentes a 100% (W100) e 50% da evapotranspiração diária (W50) e quatro tratamentos com atenuadores: controle (água destilada), AS (550 mg L-1), prolina (690 mg L-1) e 690 mg L-1 prolina + 550 mg L-1 AS. Os elicitores promoveram alterações no metabolismo osmótico e antioxidante, o que pode contribuir para o mecanismo de tolerância das plantas de feijão-caupi sob restrição hídrica. A aplicação de ácido salicílico aumentou a síntese de osmorreguladores, a concentração de proteínas e modulou a atividade de enzimas antioxidantes em plantas de feijão-caupi sob estresse. A concentração de prolina aumentou sinergicamente nas plantas tratadas com prolina e AS, principalmente em 50% de reposição de água.
ABSTRACT Exogenous applications of chemical compounds stimulate changes in plant metabolism and promote tolerance to different environmental stresses, including water deficit. This study aimed to evaluate the ability of salicylic acid (SA) and proline (PRO) to reduce water stress in a traditional variety of cowpea in a typical Brazilian semiarid climate. A completely randomized design was used in a 2 × 4 factorial scheme, with five replicates. Two irrigation regimes were evaluated corresponding to 100% (W100) and 50% of daily evapotranspiration (W50), respectively, with the addition of the following four attenuators: control (distilled water), SA (550 mg L-1), PRO (690 mg L-1), and 690 mg L-1 PRO + 550 mg L-1 SA. The treatments promoted changes in osmotic and antioxidant metabolism, which may contribute to the tolerance mechanisms of cowpea plants to water stress. The application of SA increased osmoregulator synthesis and protein concentrations, and modulated antioxidant enzyme activity in the cowpea plants under water stress. PRO concentrations increased synergistically in plants treated with PRO and SA, particularly in 50% of water replacement.

Abstract Background Controlling blood pressure and glycemic levels is a challenge that requires innovative solutions. Objective To assess the feasibility of implementing a text message intervention among low-income primary care patients, as well as to assess self-reported behavioral change. Methods A set of 200 text messages was developed on healthy eating, physical activity, adherence, and motivation. Participants from Vale do Mucuri, MG, Brazil diagnosed with diabetes or hypertension or undergoing screening for those diseases, received 5 to 8 messages per week for 6 months. They answered a questionnaire to report their satisfaction and behavioral changes. Results Of the 136 patients, 117 (86.0%) answered the questionnaire. Most reported that the messages were very useful (86.3%), easy to understand (90.6%), and were very helpful for behavioral change (65.0%); 84.6% reported that they had started eating healthier. The most frequent reported lifestyle changes were: improved diet quality (85.5%), reduced portions (65.8%), and weight loss (56.4%). The majority of patients shared the messages (60.7%) with family or other acquaintances, considered the number of messages to be adequate (89.7%) and would recommend the program to others (95.7%). Conclusion An intervention based on text messages to promote behavioral change in patients with hypertension or diabetes in primary care is feasible in low-resource settings. Future studies are needed to assess the program’s long-term effects on clinical outcomes. solutions lowincome low income selfreported self 20 activity adherence motivation Mucuri MG diseases months 13 11 86.0% 860 86 0 (86.0% 86.3%, 863 86.3% , 3 (86.3%) 90.6%, 906 90.6% 90 (90.6%) 65.0% 650 65 (65.0%) 846 84 84.6 healthier 85.5%, 855 85.5% 85 (85.5%) 65.8%, 658 65.8% (65.8%) 56.4%. 564 56.4% . 56 4 (56.4%) 60.7% 607 60 7 (60.7% acquaintances 89.7% 897 89 (89.7% 95.7%. 957 95.7% 95 (95.7%) lowresource resource settings programs s longterm long term outcomes 2 1 86.0 (86.0 86.3 (86.3% 90.6 9 (90.6% 65.0 (65.0% 84. 85.5 (85.5% 65.8 (65.8% 56.4 (56.4% 60.7 (60.7 89.7 (89.7 95.7 (95.7% 86.

Abstract Background ST-segment elevation myocardial infarction (STEMI) is defined by symptoms accompanied by typical electrocardiogram changes. However, the characterization of ischemic symptoms is unclear, especially in subgroups such as women and the elderly. Objectives To analyze the typification of ischemic symptoms, temporal metrics and observe the occurrence of in-hospital outcomes, in the analysis of predictive scores, in patients with STEMI, in a drug-invasive strategy. Methods Study involving 2,290 patients. Types of predefined clinical presentations: typical pain, atypical pain, dyspnea, syncope. We measured the time between the onset of symptoms and demand for care and the interval between arrival at the medical unit and thrombolysis. Odds-ratios (OR; CI-95%) were estimated in a regression model. ROC curves were constructed for mortality predictors. The adopted significance level (alpha) was 5%. Results Women had a high prevalence of atypical symptoms; longer time between the onset of symptoms and seeking care; delay between arrival at the emergency room and fibrinolysis. Hospital mortality was 5.6%. Risk prediction by Killip-Kimball classification: AUC: [0.77 (0.73-0.81)] in class ≥II. Subgroups studied [OR (CI-95%)]: women [2.06 (1.42-2.99); p=0.01]; chronic renal failure [3.39 (2.13-5.42); p<0.001]; elderly [2.09 (1.37-3.19) p<0.001]; diabetics [1.55 (1.04-2.29); p=0.02]; obese 1.56 [(1.01-2.40); p=0.04]: previous stroke [2.01 (1.02-3.96); p=0.04] correlated with higher mortality rates. Conclusion Despite higher mortality rates in some subgroups, significant disparity persists in women, with delays in symptom recognition and prompt thrombolysis. We highlight the applicability of the Killip-Kimball score in prediction, regardless of the clinical presentation.

Resumo Fundamento O infarto do miocárdio com elevação do segmento-ST (IAMCSST) é definido por sintomas acompanhados por alterações típicas do eletrocardiograma. Entretanto, a caracterização dos sintomas isquêmicos não é clara, principalmente em subgrupos, como mulheres e idosos. Objetivos Analisar a tipificação dos sintomas isquêmicos, métricas temporais e observar a ocorrência de desfechos intra-hospitalares, em análise dos escores preditivos, em pacientes com IAMCSST, em estratégia fármaco-invasiva. Métodos Estudo envolvendo 2.290 pacientes. Tipos de apresentações clínicas pré-definidas: dor típica, dor atípica, dispnéia, sincope. Medimos o tempo entre o início dos sintomas à demanda pelo atendimento e o intervalo entre a chegada à unidade-médica e trombólise. Odds-ratios (OR; IC-95%) foram estimadas em modelo de regressão. Curvas ROCs foram construídas para preditores de mortalidade. Nível de significância adotado (alfa) foi de 5%. Resultados Mulheres apresentaram alta prevalência de sintomas atípicos; maior tempo entre o início dos sintomas e a procura por atendimento; atraso entre a chegada ao pronto-socorro e a fibrinólise. A mortalidade hospitalar foi de 5,6%. Predição de risco pela classificação Killip-Kimball: AUC: [0,77 (0,73-0,81)] em classe ≥II. Subgrupos estudados [OR (IC-95%)]: mulheres [2,06 (1,42-2,99); p=0,01]; insuficiência renal crônica [3,39 (2,13-5,42); p<0,001]; idosos [2,09 (1,37-3,19) p<0,001]; diabéticos [1,55 (1,04-2,29); p=0,02]; obesos 1,56 [(1,01-2,40); p=0,04]; acidente vascular cerebral prévio [2,01 (1,02-3,96); p=0,04] correlacionaram-se com maiores taxas de mortalidade. Conclusão Apesar das mais altas taxas de mortalidade em alguns subgrupos, disparidade significativa persiste nas mulheres, com atrasos no reconhecimento dos sintomas e trombólise imediata.

In this paper, the piperine (PIP) and eugenol (EUG) organic compounds were used as substrates in olefin metathesis reactions catalyzed by first-generation Grubbs catalyst (G1) - [RuCl2(PCy3)2(=CHPh)], Cy is cyclohexyl and Ph is phenyl, in a one-pot system. The reactions occurred at 50 ºC, for 24, 48, or 96 h using the two substrates simultaneously in the ratio Ru:PIP:EUG of 1:1:1 and 1:10:10 mol. The results were evaluated by GC-MS, discussed in terms of the electronic and steric characteristics of the G1, and the structural proprieties of the substrates. In the Ru:PIP:EUG ratio of 1:1:1 mol, a dimeric species was observed for the olefin metathesis of EUG, in all time studied and in an additional experiment at 70 ºC for 48 h. When the Ru:PIP:EUG ratio was 1:10:10 mol, this dimer was not observed. Isomerization processes also were observed at all temperatures and catalyst:substrates ratio. The reaction yield increased with the raise of substrates amount. There was no cross-metathesis reaction. This fact was attributed to the chelating effect of the double coordination of the PIP to the catalyst.

Resumo Fundamentos Uma metodologia para identificação de pacientes portadores de aneurisma de aorta ascendente (AAAs) sob alto risco de remodelamento aórtico não está completamente definida. Objetivo Esta pesquisa objetiva caracterizar numericamente o fluxo sanguíneo aórtico, relacionando a distribuição do estresse mecânico resultante com o crescimento de AAAs. Métodos Estudo analítico, observacional, unicêntrico, em que um protocolo de fluidodinâmica computacional (CFD - Computacional Fluid Dynamics) foi aplicado a imagens de angiotomografia computadorizada (ATC) de aorta de pacientes portadores de AAAs. Duas ATC de aorta com pelo menos um ano de intervalo foram obtidas. Dados clínicos dos pacientes foram registrados e, a partir das imagens de ATC, foram gerados modelos tridimensionais. Foram realizados estudos do campo de velocidade e estruturas coerentes (vórtices) com o objetivo de relacioná-los ao crescimento ou não do aneurisma e, posteriormente, compará-los com os dados clínicos dos pacientes. O teste de Kolmogorov-Smirnov foi utilizado para avaliar a normalidade da amostra e o teste não-paramétrico Wilcoxon signed-rank foi aplicado para comparações de dados pareados entre os ângulos aórticos. A significância estatística foi fixada em 5%. Resultados Para o grupo que apresentou crescimento do aneurisma, a incidência do jato na parede aórtica gerou áreas de recirculação posterior ao jato, induzindo à formação de vórtices complexos, ocasionando um incremento na pressão média no endotélio aórtico. O grupo sem crescimento do aneurisma apresentou diminuição na pressão média. Conclusão Este estudo piloto mostrou que a CFD baseada em ATC pode, em um futuro próximo, ser uma ferramenta auxiliar na identificação dos padrões de fluxo associados ao processo de remodelamento de AAAs.
Abstract Background A methodology to identify patients with ascending aortic aneurysm (AsAA) under high risk for aortic growth is not completely defined Objetive This research seeks to numerically characterize the aortic blood flow by relating the resulting mechanical stress distribution with AsAA growth. Methods Analytical, observational, single-center study in which a computational fluid dynamics (CFD) protocol was applied to aortic computed tomography angiogram (CTA) images of patients with AsAA. Two CTA exams taken at a minimum interval of one year were obtained. From the CTA-gathered images, three-dimensional models were built, and clinical data were registered. Study of velocity field and coherent structures (vortices) was performed aiming to relate them to the presence or absence of aneurysm growth, as well as comparing them to the patients’ clinical data. The Kolmogorov-Smirnov test was used to evaluate the normality of the distribution, and the non-parametric Wilcoxon signed-rank test, for non-normal distribution, was used to compare the paired data of the aortic angles. Statistical significance was set at 5%. Results The incident jet in the aortic wall generated recirculation areas in the posterior region of the jet, inducing complex vortices formation in the group with aneurysm growth, leading to an average pressure increase in the ascending aortic wall between exams. In the group without aneurysm growth, the average pressure decreased. Conclusion This pilot study showed that CFD based on CTA may in the near future be a tool to help identify flow patterns associated with AsAA remodeling process.

Abstract Kavain is one of the main kavalactones of Piper methysticum (Piperaceae) with anxiolytic, analgesic, and antioxidant activities. Therefore, the aim of the study was to evaluate the cytotoxic, mutagenic, and antimutagenic potential of kavain in Allium cepa cells. Roots of A. cepa were transferred to the negative (2% acetone) and positive (10 µg/mL of Methylmethanesulfonate, MMS) controls and to the concentrations of kavain (32, 64 and 128 µg/mL) for 48 h. A total of 5,000 meristematic cells were analyzed under an optical microscope to determine the mitotic index, mean number of chromosomal alterations and percentage of damage reduction. Data were analyzed by Kruskal-Wallis test (p <0.05). All concentrations of kavain were not cytotoxic and did not show significant chromosomal changes when compared to 2% acetone. Kavain showed a cytoprotective effect in the pre (128 μg/mL) and in the post-treatment (32 and 64 μg/mL) and reduced damage against the mutagenic action of MMS in all concentrations of the pre and simultaneous and at the highest of post (128 μg/mL). Kavain promoted a significant reduction in micronuclei, nuclear buds and chromosomal losses in relation to MMS. The observed data indicate the importance of kavain for the inhibition of damage and chemoprevention.
