RESUMO A simbiose do feijão comum com bactérias fixadoras de nitrogênio proporciona uma abordagem eficiente para a produção de alimentos sustentável e econômica. Portanto, este estudo teve como objetivo avaliar a aplicação de estratégias custo-efetivas de manejo de nitrogênio no cultivo orgânico do feijão comum, incluindo a aplicação de esterco de aves e fertilizante orgânico líquido, inoculação de sementes e coinoculação com bactérias diazotróficas (Azospirillum brasilense e/ou Rhizobium tropici), e inoculação suplementar com Rhizobium tropici. O estudo durou três anos em um campo de cultivo orgânico bem estabelecido (2018) e uma área inicial de cultivo orgânico (2019 e 2020) no Brasil. O delineamento foi em blocos casualizados em esquema fatorial 2 × 5 (2018) e 2 × 6 (2019 e 2020), com quatro repetições. A estratégia mais lucrativa envolve a inoculação de sementes com Azospirillum brasilense e inoculação adicional com Rhizobium tropici no estádio V4-5 (quinta folha trifoliada totalmente expandida), enquanto a estratégia mais cara foi a aplicação de esterco de aves no estádio V3 (primeira folha trifoliada totalmente expandida). Assim, o uso de bactérias diazotróficas para inoculação e coinoculação de sementes (Azospirillum brasilense e/ou Rhizobium tropici) garantiu retorno financeiro e rentabilidade do sistema no cultivo do feijão comum. econômica Portanto custoefetivas custo efetivas líquido eou ou tropici, , 2018 (2018 2019 (201 2020 Brasil 2020, repetições V45 V V4 V4- quinta expandida, expandida expandida) primeira expandida. .

ABSTRACT The symbiosis of common beans with nitrogen-fixing bacteria provides an efficient approach to sustainable and economical food production. Therefore, this study aimed to evaluate the application of cost-effective nitrogen management strategies in organic common bean cultivation, including the application of poultry manure and organic liquid fertilizer, seed and co-inoculation with diazotrophic bacteria (Azospirillum brasilense and/or Rhizobium tropici), and supplementary Rhizobium tropici inoculation. The study spanned three years in a well-established organic cultivation field (2018) and an initial organic cultivation area (2019 and 2020) in Brazil. It was arranged in a randomized blocks design in a 2 × 5 (2018) and 2 × 6 (2019 and 2020) factorial scheme, with four replicates. The most profitable strategy involves seed inoculation with Azospirillum brasilense and additional inoculation with Rhizobium tropici at stage V4-5 (fifth trifoliate leaf fully expanded), while the most costly strategy was the application of poultry manure at the V3 stage (first trifoliate leaf fully expanded). Thus, the use of diazotrophic bacteria for seed inoculation and co-inoculation (Azospirillum brasilense and/or Rhizobium tropici) ensured financial returns and system profitability in common bean cultivation. nitrogenfixing fixing production Therefore costeffective cost effective fertilizer coinoculation co andor or tropici, , wellestablished well established 2018 (2018 2019 (201 2020 Brazil scheme replicates V45 V V4 V4- fifth expanded, expanded expanded) first expanded. .

Resumo Relatos da medicina popular costumam atuar como referencial para o desenvolvimento de novos fármacos a partir de moléculas naturais com ações terapêuticas para doenças de alta gravidade e prevalência como o câncer. Bromelia antiacantha Bertol. é uma espécie da família Bromeliaceae, considerada uma planta alimentícia não convencional (PANC), encontrada nas regiões sul e centro-oeste do Brasil. Apesar do alto teor nutritivo e potencial farmacológico de seus frutos, poucos estudos científicos relatam suas ações biológicas. Desta forma, este estudo avalia o perfil fitoquímico de extratos aquoso e etanólico obtidos de frutos de B. antiacantha, bem como a sua possível ação antioxidante, antitumoral e citotóxica. O extrato aquoso apresentou compostos fenólicos e flavonoides, enquanto os extratos etanólicos apontam a presença de flavonóides e cumarina em sua composição, independente da região de coleta. O extrato etanólico demonstrou efeito antioxidante mais promissor do que o extrato aquoso e também induziu uma inibição significativa na viabilidade de células humanas de câncer cervical da linhagem SiHa. Além disso, o tratamento com ambos extratos não alterou a viabilidade de células não tumorais da linhagem de queratinócitos humanos imortalizados (HaCaT). Estes dados trazem novas informações sobre extratos obtidos de uma espécie vegetal nativa, comestível e já utilizada tradicionalmente, mas abrindo novas perspectivas quanto a possíveis aplicações terapêuticas.
Abstract Reports from popular medicine usually act as a basis for the development of new drugs from natural compounds with therapeutic actions for serious diseases and prevalence such as cancer. Bromelia antiacantha Bertol. is a species of the Bromeliaceae family, considered an unconventional food plant, found in the south and midwest regions of Brazil. Despite the high nutritional content and pharmacological potential of its fruits, few scientific studies report its biological actions. Thus, this study evaluates the phytochemical profile of aqueous and ethanol extracts obtained from B. antiacantha fruits, as well as their possible antioxidant, antitumor, and cytotoxic activities. The aqueous extract exhibited phenolic compounds and flavonoids, while ethanol extracts indicated the presence of flavonoids and coumarin in their composition, regardless of the region of collection. The ethanolic extract demonstrated a more promising antioxidant effect than the aqueous extract and also induced a significant inhibition in the viability of human cervical cancer cells of the SiHa strain. In addition, treatment with both extracts did not alter the viability of non-tumor cells of the immortalized human keratinocyte lineage (HaCaT). These results bring new data about extracts obtained from a native plant, edible and traditionally used in popular medicine, opening new perspectives for its possible therapeutic application.

It is essential to diversity energy sources for ensuring sustainability. While hydrogen is considered a promising energy storage medium, its potential hinges on the development of efficient photocatalysts for green production. In addressing this challenge, we evaluated the performance of a heterojunction system composed of non-stoichiometric molybdenum oxides (MoO3−x) and cadmium sulfide (CdS) quantum dots (QDs) for water splitting. MoO3−x were synthesized via gamma irradiation of the MoO3 in the presence of formic acid (FA), while CdS-MPA QDs were electrosynthesized. The heterojunction was formed through adsorption. The structural and electronic characterization revealed a progressive transformation from MoO3 to MoO3−x and MoO3−x/CdS-MPA QDs, demonstrating enhanced water-splitting performance. Upon evaluation, the study revealed a charge transfer mechanism, highlighting the significance of relative band positions between MoO3−x and CdS-MPA QDs in promoting eco-friendly hydrogen evolution and methanol processing. Thus, we suggest that the synergism between MoO3−x and CdS-MPA QDs semiconductors makes the heterojunction system a promising solution for photocatalytic production of hydrogen and oxygen. sustainability medium challenge nonstoichiometric non stoichiometric MoO3x MoOx x MoO (MoO3−x CdS (CdS (QDs splitting FA, FA , (FA) CdSMPA MPA electrosynthesized adsorption MoO3−x/CdSMPA MoO3xCdSMPA MoOxCdSMPA MoO3−x/CdS watersplitting evaluation mechanism ecofriendly eco friendly processing Thus oxygen (FA xCdSMPA MoO3xCdS MoOxCdS xCdS

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.

The aim of this work was to construct and characterize dye-sensitized solar cells (DSSC) using alternative materials and low-cost equipment. Instead of using the TiO2 semiconductor, a water-based white paint pigment was employed as a substitute. This pigment, when combined with natural dyes, absorbs visible light and acts as the photoelectrode. Pencil graphite was utilized to create the conductive layer, serving as the positive electrode. Lugol’s solution was employed as the electrolyte to establish electrical contact between the two electrodes. These materials were assembled between two glasses with a conductive surface made of tin oxide doped with fluorine (FTO glass). Subsequently, the assembled devices were exposed to three types of lamps: daylight (45 W), LED (15 W), and halogen (105 W), all positioned at the same height as the solar cell. Voltage and current measurements were taken using a simple multimeter. These results enabled the correlation of theoretical concepts related to absorption (dye) and light emission (lamp) ranges, different types of anchoring groups, and the dye-semiconductor anchoring mode. The voltage and current production were found to depend on the type of lighting source. However, it became evident that several factors beyond those mentioned strongly influenced the energy production mode of the solar cell. dyesensitized dye sensitized DSSC (DSSC lowcost low cost equipment TiO semiconductor waterbased water based substitute dyes photoelectrode layer electrode Lugols Lugol s electrodes FTO glass. glass . glass) Subsequently lamps 45 (4 W, W , W) 15 (1 105 (10 cell multimeter (dye lamp (lamp ranges groups dyesemiconductor source However 4 ( 1 10

ABSTRACT This study structures objectives and sustainable-development alternatives for the Amazon Forest, based on the Amazônia 4.0 project. Value-Focused Thinking and Value-Focused Brainstorming were adopted. Amazônia 4.0 presents a new paradigm for the rainforest development, emphasizing the sustainable use of the biodiversity with innovative technologies. The project’s strategic objective is to promote the standing-forest’s value, through four fundamental objectives: adding value to products, creating means for industrialization, developing local economy and empowering communities. Alternatives include local mobile bio-industries, certified products, and educational partnerships. Challenges identified involve reevaluating the traditional credit system, creating new public policies, engaging numerous stakeholders, and addressing the lack of infrastructure. The project is in line with the Living Amazon Vision, proposed by the Science Panel for the Amazon, and takes the form of an operational bioeconomy project (already being tested). This study’s methodology can be applied to other initiatives seeking sustainable development in ecologically valuable regions. sustainabledevelopment Forest 40 4 0 4.

Resumo Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causa perdas consideráveis às lavouras de soja no Brasil e em vários outros países da América do Sul. A aplicação de inseticidas biológicos pode ser uma alternativa eficaz para suprimir esta praga. O objetivo deste estudo foi avaliar a eficácia de inseticidas microbiológicos formulados a partir dos fungos Beauveria bassiana + Metarhizium anisopliae (Bometil) e B. bassiana (Ballvéria), e bactéria Bacillus thuringiensis (Acera) isoladamente e em combinação com os inseticidas químicos fipronil, etiprole e clorpirifós, contra adultos de M. armatus. Os inseticidas à base de B. bassiana + M. anisopliae foram mais patogênicos que os à base de B. bassiana, causando taxas de mortalidade acumuladas nos dez dias com 85,0 e 65,0% respectivamente. Em contraste, B. thuringiensis causou 92,5% de mortalidade. Estes produtos sozinhos e em combinação foram eficazes para o controlo nas suas concentrações mais baixas. Portanto, o uso de inseticidas microbiológicos individualmente ou em combinação com inseticidas químicos é uma alternativa promissora para o manejo integrado de M. armatus.

Abstract Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causes considerable losses to soybean crops in Brazil and several other South American countries. Applying biological insecticides can be an effective alternative to suppressing this pest. The objective of this study was to assess the efficacy of microbiological insecticides formulated from the fungi Beauveria bassiana + Metarhizium anisopliae (Bometil) and B. bassiana alone (Ballvéria), and the bacterium Bacillus thuringiensis (Acera) alone and in combination with the chemical insecticides fipronil, ethiprole and chlorpyrifos, against M. armatus adults. The insecticides based on B. bassiana + M. anisopliae were found to be more pathogenic than those based on B. bassiana, causing cumulative mortality rates in the ten days of 85.0 and 65.0% respectively. In contrast, B. thuringiensis caused 92.5% mortality. These products alone and in combination were effective for control at their lowest concentrations. Therefore, the use of microbiological insecticides individually or in combination with chemical insecticides is a promising alternative for the integrated management of M. armatus.

ABSTRACT: Crotalaria spectabilis seed poisoning has been reported in cattle on rural properties in Diamantino and Campo Verde municipalities in Mato Grosso, Brazil. The disease appeared 75 to 120 days after the animals were fed a diet contaminated with C. spectabilis seeds. Clinically, the animals showed a lack of appetite, progressive weight loss, apathy, photosensitivity, lateral recumbency, and death. Some animals developed neurological manifestations as a consequence of hepatic encephalopathy. In total, 37 cattle died, and six cattle were necropsied. The main macroscopic changes consisted of ascites and a firm and decreased liver with an irregular surface and multifocal pale yellowish discoloration. Microscopically, hepatocyte loss with fibrosis, megalocytosis and bile duct proliferation was observed. Animals with severe hepatic damage also had status spongiosus in the central nervous system. Furthermore, a hepatic biopsy of 15 cows who consumed contaminated grains but did not develop clinical disease revealed histologic liver changes similar to necropsied animals.

Abstract The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae), generally reaches pest status in stored grain. Chemical control is the most used method for population suppression, which can cause adverse impacts, thus creating a need for alternatives such as using inert powders. The present work aims to verify the effect of different concentrations of different types of inert powders on the mortality of S. zeamais in the laboratory. To this end, the experiments were carried out in a completely randomized design, with 13 treatments and four replications, ten adults per replication, where the effect of different inert powders (basalt powder, gypsum powder, and diatomaceous earth) was tested at concentrations of 0.025 g, 0.05 g, 0.1 g and 0.2 g/20 g of corn grains. Variance, normality, and homoscedasticity tests were applied in addition to controlling efficiency (CE%), median lethal time (TL50), and survival curves. All treatments caused mortality in S. zeamais, and all concentrations with diatomaceous earth were more efficient, with 100% mortality at 20 days, followed by the treatment of 0.2 g of gypsum powder/20 g of corn grains, with superior efficiency, to 95% in 20 days and 100% in 30 days. The results indicated that treatments with diatomaceous earth had the highest mortality rate and the best average survival time. weevil Motschulsky 185 Coleoptera (Coleoptera Curculionidae, Curculionidae , Curculionidae) grain suppression impacts S laboratory end design 1 replications replication basalt powder 0025 0 025 0.02 005 05 0.0 01 0. 02 2 g20 g/2 grains Variance normality CE%, CE CE% (CE%) TL50, TL50 TL (TL50) curves efficient 100 powder20 powder/2 95 3 18 002 00 g2 g/ (CE% TL5 (TL50 10 powder2 powder/ 9 (CE (TL5 (TL

Abstract We examined pesticide contamination in honey from Africanized honey bees in two different seasons, and evaluated the concentration and incidence of these compounds in georeferenced apiaries to provide relevant information for food safety and environmental quality. The land use and occupation of the region were evaluated by selecting 15 apiaries and georeferencing three randomly selected colonies of Africanized honey bees within each apiary. Honey samples were collected during two seasons, and three organochlorine pesticides (p.p`-DDE, Mitotane and Bicyclo[2.2.1]) and four organophosphate pesticides (Ethoprophos, Methyl Parathion, Chlorpyrifos and Fenchlorphos) were analyzed in the honey using gas chromatography-mass spectrometry. 80% of the apiaries showed a predominance of agricultural land use in the foraging areas of the bees. There was a higher concentration of pesticides in samples collected during Season I compared to Season II. There were differences in the proportion of samples contaminated with pesticides between seasons. Some honey samples showed concentrations of the chlorpyrifos pesticide above the levels recommended by Brazilian legislation. Pesticide contamination of honey is not limited to specific application season, indicating the persistent presence and easy availability of pesticides, including banned pesticides not sold or prescribed by agronomists, potentially smuggled from neighboring countries. seasons quality 1 apiary p.p`DDE, ppDDE p.p` DDE, p DDE (p.p`-DDE Bicyclo2.2.1 Bicyclo221 Bicyclo 2.2.1 2 Bicyclo[2.2.1] Ethoprophos, Ethoprophos (Ethoprophos Parathion Fenchlorphos chromatographymass chromatography mass spectrometry 80 II legislation season agronomists countries p.p`DDE pp p.p Bicyclo2 Bicyclo2.2.

Infections in fruits caused by fungi reduce the quantity and quality of food for human consumption, in addition to causing economic losses. In this sense, this study aimed to address the effects of eugenol nanocapsules (NCs) based on chitosan and carboxymethylcellulose in protecting nectarines against Monilinia fructicola, a brown rot agent, a worldwide important disease. NCs were prepared by layer-by-layer (LbL) self-assembly starting from an anionic template and deposition with up to two polymeric layers. The hydrodynamic diameters ranged from 158 nm (nanoemulsion), 360 nm (one polymeric layer) to 398 nm (two polymeric layers). NCs presented, during the in vitro release, the release of eugenol following a first order process. In addition to being in the region of stability (zeta potential ca. |30| mV), the capsules showed good adhesion to the nectarine surface. In relation to brown rot, the eugenol NCs with chitosan proved to be the best formulation compared to nanoemulsion and NCs with two polymeric layers for its control, increasing the probability that the fruits remain without symptoms, even after 7 days. Therefore, this study demonstrated that chitosan NCs containing eugenol could be an alternative to preserve fruit for longer periods in post-harvest. consumption losses sense (NCs fructicola agent disease layerbylayer layer LbL (LbL selfassembly self assembly 15 nanoemulsion, , (nanoemulsion) 36 one 39 . layers) presented process zeta ca 30 |30 mV, mV mV) surface control symptoms days Therefore postharvest. postharvest post harvest. harvest post-harvest 1 (nanoemulsion 3 |3 |

ABSTRACT Introduction: There is a lack of information about cardiac surgery training and professional practice in Latin American (LATAM) countries. This study is the first comparative analysis of cardiac surgical training and professional practice across LATAM and provides the fundamentals for future academic projects of the Latin American Association of Cardiac and Endovascular Surgery (LACES). Methods: International survey-based comparative analysis of the training and professional practice of cardiac surgeons across LATAM. Trainees (residents/fellows) and staf (graduated) surgeons from LATAM countries were included. Results: A total of 289 respondents (staf surgeons N=221 [76.5%]; residents/fellows N=68 [23.5%]) from 18 different countries participated in the survey. Most surgeons (N=92 [45.3%]) reported being unsatisfied with their salaries. Most respondents (N=181 [62.6%]) stated that it was difficult to obtain a leadership position, and 149 (73.8%) stated that it was difficult to find a job after completing training. Only half of the trainee respondents (N=32 [47.1%]) reported that their program had all resident spots occupied. Only 22.1% (N=15) of residents/fellows were satisfied with their training programs. The majority (N=205 [70.9%]) of respondents would choose cardiac surgery as their specialty again. Most surgeons (N=129 [63.9%]) and residents/fellows (N=52 [76.5%]) indicated that the establishment of a LATAM cardiac surgery board examination would be beneficial. Conclusion: Modernization and standardization of training, as well as greater access to opportunities, may be required in LATAM to increase professional satisfaction of cardiac surgeons and to reduce disparities in the specialty. Such changes may enhance the regional response to the dynamic challenges in the feld. Introduction (LATAM LACES. LACES .

Abstract The photoluminescent behavior of Eu-doped Sr3Al2O6 obtained by highly efficient solution combustion synthesis is reported. In order to understand the influence of the fuel on the synthesis, the stoichiometric quantity and an excess of fuel were evaluated. By adjusting the amount of fuel, different luminescence responses were obtained, allowing europium cations incorporation into the Sr3Al2O6 lattice to serve as effective luminescence activators in such a short time during the rapid combustion synthesis process. The higher amount of fuel in the presence of the oxidizing agent produced Sr3Al2O6:Eu particles with higher phosphorescence brightness, owing to the increase of the reduction process from Eu3+ to Eu2+. The synthesized phosphor showed an intense band emission centered at 515 nm and could be excited over a broad spectral range in the UV-visible region. Particles having nanostructured flake-type morphology were obtained, which was considered a micro-nanofunctional candidate for practical applications.

Abstract Ceratitis capitata (Wiedemann, 1824) is an insect of major economic importance in the mango orchards of the submedium of the São Francisco River Valley, the main area of mango production and exportation in Brazil. To provide alternatives for the management of C. capitata, toxic baits based on alpha-cypermethrin (Gelsura®) and spinosad (Success® 0.02 CB) were evaluated in three commercial mango experiments during two consecutive harvests: 2016/2017 (experiment 1 - area 1) and 2017/2018 (experiment 2 -area 2 and experiment 3 - area 3). According to the results, there was a large reduction in the infestation of C. capitata after five sequential applications of the alpha-cypermethrin (6 g.ha-1) and spinosad (0.38 g.ha-1) toxic baits performed at seven-day intervals during mango fruit ripening in all experiments and years (harvest) evaluated. Compared with the untreated plots, the plots with alpha-cypermethrin and spinosad applications showed a significant reduction in the damage induced (fallen fruits and/or on trees) by C. capitata. The management of C. capitata in mango orchards can include the use of the toxic bait based on alpha-cypermethrin, which represents an alternative to rotate with spinosad toxic bait in the São Francisco River Valley.
