This study investigated the removal of contaminants in water by adsorption on thermoplastic starch (TPS) and kraft lignin (KL) composites. A study on the desorption of methylene blue (MB) and methyl orange (MO) dyes in water was also carried out, followed by the photodegradation of solutions containing dissolved dyes. Initially, the surface morphology of the TPS and TPS-KL films was analyzed by scanning electron microscopy, revealing advantageous characteristics for efficient adsorption of contaminants. Fourier transform infrared spectroscopy (FTIR) analysis made it possible to characterize the TPS and TPS-KL composites. The results demonstrate the reversibility of the process and confirm the lack of permanent chemical modification in the polymer matrix, indicating that the adsorption/desorption process is physical rather than chemical. This suggests that the adsorbent material can be reused without losing its fundamental structural properties. Furthermore, the study allows for verification of the chemical changes on the surfaces of the materials involved. Ultraviolet-visible spectroscopy (UV-Vis) results show that for MO, both substrates exhibited low adsorption capacity, with efficiency values close to 20%. In contrast, for MB, both composite materials displayed excellent dye adsorption rates, achieving efficiencies of 78% or higher. The photodegradation of adsorbed dyes revealed promising results.

RESUMO O aumento da fertilidade do solo no cultivo de hortaliças apresenta desafios, notadamente usando adubo verde de espécies espontâneas do bioma Caatinga, como a flor-de-seda (Calotropis procera [Ait.] R. Br.). Este estudo teve como objetivo avaliar e otimizar as eficiências física e econômica da rúcula em monocultivo, influenciadas por quantidades variáveis de biomassa de flor-de-seda. Um delineamento em blocos casualizados com sete tratamentos e cinco repetições foi utilizado. Os tratamentos consistiram de diferentes quantidades de biomassa de C. procera (20, 40, 60, 80 e 100 t ha-1 em base seca), juntamente com dois tratamentos adicionais em cada bloco: um controle (sem fertilização) e um com fertilização mineral. A cultivar de rúcula "Cultivada" foi adubada para máxima eficiência produtiva usando 63,31 t ha-1 de biomassa seca de C. procera, rendendo 8,45 t ha-1. A maior eficiência agroeconômica otimizada, refletindo uma renda líquida de R$ 111.007,64 por hectare, foi alcançada com 59,26 t ha-1 de biomassa seca de C. procera. A taxa de retorno foi de R$ 4,65 para cada real investido, com um índice de rentabilidade de 77,38%. Assim, utilizar biomassa de C. procera como adubo verde é uma tecnologia viável para produtores de rúcula em regiões semiáridas. desafios Caatinga flordeseda flor seda Calotropis Ait. Ait [Ait.

ABSTRACT Enhancing soil fertility in vegetable cultivation presents challenges, notably using green manure from spontaneous species in the Caatinga biome, such as roostertree (Calotropis procera [Ait.] R. Br.). This study aimed to evaluate and optimize the physical and economic efficiencies of monocropped arugula, as influenced by varying amounts of roostertree biomass. We employed a randomized block design with seven treatments and five replications. Treatments involved different quantities of C. procera biomass (20, 40, 60, 80, and 100 t ha-1 on a dry basis), along with two additional treatments in each block: a control (no fertilization) and one with mineral fertilization. The "Cultivada" arugula cultivar was fertilized for maximum productive efficiency using 63.31 t ha-1 of C. procera dry biomass, yielding 8.45 t ha-1. The highest optimized agroeconomic efficiency, reflecting a net income of BRL 111,007.64 per hectare, was achieved with 59.26 t ha-1 of C. procera dry biomass. The return rate was BRL 4.65 for every real investment, with a profitability index of 77.38%. Thus, using C. procera biomass as green manure is a viable technology for arugula producers in semi -arid regions. challenges biome Calotropis Ait. Ait [Ait. R Br.. Br Br. .

ABSTRACT OBJECTIVE The COVID-19 pandemic has raised numerous concerns regarding its effects on individuals’ health and lifestyle. We aim to analyze potential changes in adolescent sleep patterns from before and during the pandemic and identify specific predictors of changes. METHODS A subgroup of adolescents from a population-based birth cohort from Pelotas, Brazil, was assessed pre-pandemic (T1, November-2019 to March-2020) and peri-pandemic (T2, August-2021 to December-2021) in in-person interviews (n = 1,949). Sleep parameters, including sleep duration and latency time on workdays and free days, as well as social jetlag (SJL), were assessed using the Munich ChronoType Questionnaire (MCTQ). Socio-demographic, pre-pandemic, and pandemic-related predictors were analyzed. Changes in sleep parameters from T1 to T2 were estimated by multivariate latent change score modeling. RESULTS The latent change factor shows a significant mean increase in workday sleep duration (M = 0.334, p < 0.001), workday sleep latency (M = 0.029, p = 0.002), and free day sleep latency (M = 0.021, p = 0.034), and a decreased in SJL (M = −0.758, p < 0.001) during the pandemic. Female adolescents presented higher increases in workday sleep duration. Adolescents who adopted a stricter social distancing level during the pandemic presented greater increases in workday sleep duration and smaller reductions in SJL. Self-evaluated insomnia during the pandemic predicted lower increases in workday and free day sleep duration and higher increases in workday and free day sleep latency. CONCLUSION The COVID-19 outbreak brought certain advantages regarding increased sleep duration and reduced SJL. However, the observed increase in sleep latency and the influence of self-reported insomnia could be related to psychological distress inherent to the pandemic.

Complex oxides can present interesting semiconductor properties since the simultaneous presence of different metallic cations can modulate the conduction and valence band edges, affecting the bandgap energy, the onset potential for reactions and also the photocatalyst long-term stability. Here, we demonstrated that the synthesis of multinary oxides, very challenging using “traditional” methodologies, can be fast achieved by melting the precursor binary oxides in an arc furnace. As a proof of concept, arc-melting a mixture of Bi2O3 and V2O5 (Bi:V molar ratio of 1:1.05) resulted in almost pristine BiVO4 (97.3% from Rietveld refinement of X-ray diffraction (XRD) data); photoelectrochemical (PEC) measurements indicated a promising application as a photoanode for O2 evolution reaction. Conversely, the arc-melting of Bi2O3 and WO3 mixture (Bi:W molar ratio of 2:1.15) resulted in the biphasic Bi2WO6/Bi2W2O9; preliminary PEC analysis revealed characteristics of n-type semiconductor electrode with photoactivity under UV irradiation. Finally, the hierarchical Ag@α-AgVO3/Fe2O3 consisted of micrometric Fe2O3 particles decorated by AgVO3 nanoribbons and Ag nanoparticles, was obtained from melting Ag2O, Fe2O3 and V2O5 as precursors (Ag:Fe:V molar ratio of 3:1:2); PEC measurements also revealed possible application as a photoanode. The results for these three materials demonstrated the arc-synthesis as a fast, effective and scalable methodology for synthesizing complex oxides. edges energy longterm long term stability Here traditional “traditional methodologies furnace concept arcmelting BiO Bi O Bi2O VO V V2O BiV 11.05 1105 1 1.05 05 1:1.05 BiVO 97.3% 973 97 3 (97.3 Xray X ray XRD (XRD data data) (PEC reaction Conversely WO BiW W 21.15 2115 2 1.15 15 2:1.15 Bi2WO6/Bi2W2O9 Bi2WO6Bi2W2O9 BiWOBiWO Bi2WO6 Bi2W2O9 ntype n type irradiation Finally Ag@αAgVO3/Fe2O3 AgαAgVO3Fe2O3 AgαAgVOFeO Ag@α AgVO3/Fe2O3 α AgVO Fe Ag@α-AgVO3/Fe2O FeO Fe2O nanoparticles Ag2O AgO AgFeV 312 3:1:2) arcsynthesis 11 11.0 110 105 1.0 0 1:1.0 97.3 9 (97. 21 21.1 211 115 1.1 2:1.1 Bi2WO6/Bi2W2O Bi2WO6Bi2W2O BiWO Bi2WO Bi2W2O αAgVO3 αAgVO Ag@αAgVO3/Fe2O AgαAgVO AgαAgVO3Fe2O Agα AgVO3Fe2O3 AgVOFeO AgVO3/Fe2O 31 3:1:2 11. 10 1. 1:1. 97.

The process of photosynthesis involves the absorption of light energy by photosynthetic pigments found in the thylakoid membrane of chloroplasts in order to produce chemical energy. In the presence of photosynthetic inhibitors, plant development is affected mainly by the reduction of the electron chain, which leads to growth inhibition. In this context, chlorophyll a (Chl a) fluorescence is an important technique used to identify the effects of inhibitors on the photosynthetic apparatus employing the JIP-test, which correlates the Chl a fluorescence transient to biophysical parameters, providing valuable information about the efficiency of photosystems I and II. Natural products have been highlighted as photosynthesis inhibitors due to the continued use of synthetic herbicides, which leads to the development of invasive plants resistant to these pesticides, in addition to the toxicity caused to humans and the environment. Thus, this review describes the main applications of extracts and isolated secondary metabolites obtained from plants and microorganisms in the investigation of electron transport inhibition on photosystem II. chain context JIPtest, JIPtest JIP test, test JIP-test parameters II herbicides pesticides environment Thus

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.

Objectives: There is growing interest in examining the impacts of the coronavirus disease 2019 (COVID-19) pandemic on adolescent socioemotional development. This study aimed to examine changes in adolescent emotion regulation (ER), self-esteem (SE), and locus of control (LoC) from before to during the pandemic in a Brazilian birth cohort, and to investigate the variables associated with changes in those socioemotional competences. Methods: 1,949 adolescents from the 2004 Pelotas Birth Cohort were assessed before (T1, November 2019 to March 2020) and during (T2, August to December 2021) the COVID-19 pandemic (mean ages [SD] = 15.69 [0.19] and 17.41 [0.26], respectively). Adolescents’ socioemotional competences were assessed, including ER, SE, and LoC. Sociodemographic, pre-pandemic, and pandemic-related correlates were examined as predictors of change. Multivariate latent change score models were used in the analyses. Results: There were significant mean increases in adolescents’ ER and SE (mean ER = 1.918, p < 0.001; mean SE = 1.561, p = 0.001) and a significant mean decrease (towards internalization) in LoC levels (MLoC = -0.497, p < 0.01) during the pandemic. Factors that predicted a lower competency increase included family conflicts, harsh parenting, and maternal depressive symptoms during the pandemic. Conclusion: Despite the stress imposed by the COVID-19 pandemic, the adolescents of this cohort showed positive development in their socioemotional competences. Family-related factors emerged as important predictors of adolescent socioemotional adjustment during the study period.

Objectives: The objective of this study was to investigate the prevalence of the following risk behaviors: experimentation with cigarettes, electronic cigarettes, alcohol, substances, delinquent behavior, and sex at age 15, stratified by sex and socioeconomic position. We also investigated the prevalence of cigarette and alcohol experimentation at age 11 and the persistence and cumulative incidence of these behaviors between 11 and 15 years of age. Methods: In this cohort study, we included 3,491 11-year-olds and 1,949 15-year-olds from the 2004 Pelotas Birth Cohort. All outcomes were identified via confidential questionnaires and were analyzed as binary variables. Results: At age 11, there was a higher prevalence of cigarette experimentation among boys. At age 15, there was a higher prevalence of experimentation with alcohol, cigarettes, and substances among girls; experimentation with cigarettes and sex were more prevalent among those in a low socioeconomic position. We found a high cumulative incidence of alcohol experimentation, as well as persistent alcohol experimentation, in both boys and girls. Conclusions: Further research should clarify causal paths of the high prevalence of risk behaviors during adolescence and its increase among girls.

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 Health professionals working to mitigate the COVID-19 pandemic are one of the main risk groups for the disease, being prioritized for vaccination. Considering this, the aim of this study was to analyze the immune response of these professionals immunized with CoronaVac in the first and second doses. Blood samples were collected after the first and second doses of the vaccine (CoronaVac) and used to investigate hematological and biochemical parameters, analysis of immunoglobulin production, cytokines, and gene expression profile, as well as the identification of subsets of immune cells. Post-first dose immunological phenotypic memory (CD27+) profiles (T CD4+, TCD8+ and CD19+) showed a significant increase, as did Monocyte APCs (CD80+HLA-DR+) in relation to the second dose. The cytokines IL-2, IL-6 and IFN-° showed increased values in relation to the other analyzed cytokines. The Th2/Th17 profile in the second dose was characterized by gene expression analysis. The production of IgM and IgG after vaccination showed statistically significant values in the comparison between doses. CoronaVac showed activation of APCs monocytes, memory response of T and B lymphocytes, with immunoglobulins production. This set of responses is characterized by the Th2/Th17 immunological profile.

Resumen Objetivo: analizar los artículos sobre atención al adulto mayor durante la pandemia por COVID-19 publicados en los tres periódicos de mayor circulación en Brasil. Materiales y métodos: estudio documental, retrospectivo, exploratorio y descriptivo, con análisis cualitativo. Los datos fueron recopilados de artículos de acceso abierto publicados en la versión web de los periódicos O Globo, O Estado de S. Paulo y Correio Braziliense entre el 1 de enero y 31 de mayo de 2020. Resultados: se identificaron 2.147 artículos sobre el tema de atención al adulto mayor durante la pandemia de COVID-19 en Brasil. Al final, fueron seleccionados 25. El análisis permitió la creación de cuatro categorías: i) población de adultos mayores y riesgo de muerte por COVID-19; ii) hospitalización y sistema de salud frente a la pandemia; iii) miedo y medidas adoptadas por la población ante la pandemia; y iv) profesionales de la salud y la lucha contra la COVID-19. Conclusiones: se identificó en las noticias analizadas que la información sobre el cuidado del adulto mayor con COVID-19 se relacionaba con el temor de que la enfermedad los llevara a la UCI y, posiblemente, a la muerte, a pesar de los esfuerzos de los profesionales de la salud por asegurar el cuidado de los pacientes y evitar el colapso del sistema de salud.

The data were collected from open access articles published from January 1 to May 31, 2020, in the online version of the newspapers O Globo, O Estado de S. Paulo, and Correio Braziliense. Results: A total of 2,147 news items on the topic of elderly care in Brazil during the COVID-19 pandemic were identified. From these, a sample of 25 articles was selected. The analysis enabled the creation of four categories: i) elderly population and risk of death by COVID-19; ii) hospitalization and health system in the face of the pandemic; iii) fear and measures adopted by the population during the pandemic; and iv) health professionals and the fight against COVID-19. Conclusions: Based on the news examined, it was identified that information about the care for elderly with COVID-19 was mainly related to the fear that the disease would lead them to an ICU and, possibly, to death, despite the efforts made by health professionals to ensure patients' care and avoid the collapse of the health system.
Resumo Objetivo: analisar as matérias sobre o cuidado do idoso durante a pandemia da covid-19 publicadas por três jornais considerados de maior circulação no Brasil. Materiais e métodos: estudo documental, retrospectivo, de caráter exploratório e descritivo, com análise qualitativa. Os dados foram coletados de matérias publicadas on-line nos jornais O Globo, O Estado de S. Paulo e Correio Braziliense, de acesso livre, de 1 de janeiro a 31 de maio de 2020. Resultados: foram identificadas 2.147 notícias com a temática cuidado do idoso no Brasil durante a pandemia da covid-19 e, ao final, selecionadas 25. A análise possibilitou a criação de quatro categorias: i) população idosa e risco de morte por covid-19; ii) internação e sistema de saúde diante da pandemia; iii) medo e medidas de enfrentamento da população diante da pandemia e iv) profissionais de saúde e luta contra a covid-19. Conclusões: identificou-se, nas notícias analisadas, que as informações sobre o cuidado do idoso com covid-19 relacionaram-se ao medo de que isso os levasse à UTI e, consequentemente, a óbito, mesmo diante dos esforços dos profissionais de saúde para assegurar esse cuidado e evitar o colapso do sistema de saúde.

Abstract Staphylococcus aureus is among the major pathogens involved in food poisoning, and meat contaminated with S. aureus coagulase positive is considered a public health risk because the bacterium is resistant to several conventional antimicrobials. Mycocins are substances produced by yeasts that secrete glycoproteins, which can also be called toxin killers, they have an inhibitory action on other microorganisms. The Wickerhamomyces anomalus, is one of the microorganisms capable of producing these mycocins, resulting in the action of disturbances on the cell wall of the pathogen causing deleterious effects. This work aims to evaluate the antimicrobial activity of the mycocins produced by W. anomalus WA45 against the 29 strains of S. aureus coagulase positive isolated from bovine, porcine and chicken meat and 1 standard strain. The antimicrobial action of the mycocins present on the culture supernatant of W. anomalus WA45 was tested by microdilution and the results were satisfactory, since 100% inhibition of strains of S. aureus coagulase positive. We concluded that the mycocins present in the supernatant of W. anomalus WA45 showed antimicrobial action, being candidates for the development of new products for the biocontrol and bioconservation of meat.

Abstract The Japanese invasive jumping snail Ovachlamys fulgens is a pest of ornamental plants and an intermediate host of a nematode that causes eosinophilic meningitis. We expand its distribution to eight municipalities from Rio de Janeiro State, and one locality from the Paraná State, and generated for the first time partial sequences of the cytochrome c oxidase subunit I (COI) gene for Brazilian populations. External morphology, reproductive system, shell, radula, and jaw were also analyzed and described. Twenty-one lots were collected from Rio de Janeiro, Niterói, Magé, Miguel Pereira, Petrópolis, Teresópolis, Nova Friburgo, Bom Jardim and Paraty, in Rio de Janeiro State, and from Foz do Iguaçu, Paraná State. External morphology, shell and reproductive system were typical of O. fulgens, with some peculiarities found in the shell and radula. A single haplotype was found, which was 100% similar to sequences of COI available in GenBank for specimens from Japan and Argentina. The species seems to be adapted to many habitats and be rapidly expanding its distribution in Southeastern and Southern Brazil, and other South America countries. We highlight the importance of monitoring O. fulgens, considering its potential to compete with native mollusks, attack several plants, and be a transmitter of diseases.

ABSTRACT Nasal carriage of Staphylococcus aureus by healthcare workers is of great clinical importance as it facilitates the contamination of medical devices and cross-transmission. However, studies regarding the epidemiology and dissemination of S. aureus and Methicillin-resistant S. aureus (MRSA) within the Primary Health Care in Brazil are scarce. The current study aimed to detect and characterize S. aureus and MRSA strains from the nasal cavities of 63 healthcare working in primary health care units in order to determine the prevalence of S. aureus and MRSA, biofilm formation and resistance profile of these isolates. PCR reactions were performed for detecting mecA, icaA and icaD genes. The phenotypic antimicrobial susceptibility was assessed by the disk diffusion method and biofilm formation by the Congo Red Agar (CRA) method. The MRSA isolates were typed for the Staphylococcal Cassette Chromosome mec (SCCmec). The prevalence of nasal carriage of S. aureus was 74.6%, of which 72.3% were MRSA carrying SCCmec type I (24.4%), III (34.1%), IV (36.6%). Two (4.9%) isolates presented a non-typeable cassette by the performed technique. The antimicrobial susceptibility evaluation evidenced penicillin resistance in 66.1% of S. aureus, erythromycin resistance in 49.2%, while 37.3% were resistant to oxacillin, 28.8% to cefoxitin, 5.1% to levofloxacin and 5.1% to clindamycin. All isolates were biofilm producers and 96.6% of the strains contained the ica biofilm-forming genes (icaA and/or icaD). We have demonstrated a high prevalence of S. aureus and MRSA carriage among health care working in Primary Health Care units, the presence of SCCmec types I, III and IV, in addition to their high ability to form biofilm, factors that possibly contribute to the dissemination and persistence of these pathogens within the primary care services. These observations highlight the importance of broadening the perspective of Health Care-Associated Infections prevention, including all health care levels, which are currently little explored. In addition, the dynamics and resistance mechanisms of S. aureus transmission still need to be further clarified to enable the implementation of more effective prevention measures.
