ABSTRACT Stegomyia aegypti (Linnaeus, 1762) vectors arboviruses of public health concern in urban areas of tropical countries, so it is necessary to reduce its population. Among the control methods used, chemically synthesized molecules have been widely employed, nonetheless, the over usage of the same mechanism of action can result in the resistance selection. Considering the influence of insect resistance with the success of chemical control of vectors, this study aims to assess the susceptibility to organophosphorus of a population of S. aegypti from Paranaguá (Paraná, Brazil), after intense use of malathion during a dengue outbreak. World Health Organization susceptibility tests and expression of Acetylcholinesterase ace-1, cytochrome P450 monooxygenase CYP6N12, and α-esterases CCEae3A genes were evaluated. The mortality rate of wild females (66.5%) indicated their resistance status, furthermore, a new discriminant concentration was detected in this population (3.41%). Exclusively CYP6N12 gene was overexpressed in malathion-resistant females indicating its possible contribution to the transformation of this insecticide. Constant monitoring of insecticide resistance of current and past molecules, mainly in port areas where there is a large flow of species, is crucial for effective use of insecticide in vector control programs.

Solid and liquid fractions of hydrothermally pretreated sugarcane bagasse (SCB) were simultaneously used as substrate of a novel continuous compartmentalized reactor. The effect of four (56, 42, 28, and 14 h) hydraulic retention time (HRT) and three (0.5, 3.0, and 9.0 g L-1) chemical oxygen demand (COD) levels were evaluated on hydrogen (H2) and organic acids production. Higher H2 production and yield (686 mL and 1.63 mol mol-1 carbohydrate, respectively) were obtained under an HRT of 28 h, probably due to the Clostridium and Thermoanaerobacterium metabolisms, which accounted for almost 60% of the microbial relative abundance. Under lower and higher HRT (14 and 56 h, respectively) lactic acid prevailed without hydrogen production. Other value-added chemicals such as citric, valeric and caproic acids were also obtained according to the HRT. From the functional point of view, enzymes from the glycoside hydrolases group (GHs) potentially performed important roles in the lignocellulosic biomass bioconversion.

Abstract This study compares the effects of virus-cell interactions among SARS-CoV-2 variants of concern (VOCs) isolated in Brazil in 2021, hypothesizing a correlation between cellular alterations and mortality and between viral load and transmissibility. For this purpose, reference isolates of Alpha, Gamma, Zeta, and Delta variants were inoculated into monolayers of Vero-E6 cells. Viral RNA was quantified in cell supernatants by RT‒PCR, and infected cells were analyzed by Transmission Electron Microscopy (TEM) for qualitative and quantitative evaluation of cellular changes 24, 48, and 72 hours postinfection (hpi). Ultrastructural analyses showed that all variants of SARS-CoV-2 altered the structure and function of mitochondria, nucleus, and rough endoplasmic reticulum of cells. Monolayers infected with the Delta variant showed the highest number of modified cells and the greatest statistically significant differences compared to those of other variants. Viral particles were observed in the cytosol and the cell membrane in 100 % of the cells at 48 hpi. Alpha showed the highest mean particle diameter (79 nm), and Gamma and Delta were the smallest (75 nm). Alpha and Gamma had the highest particle frequency per field at 48 hpi, while the same was observed for Zeta and Delta at 72 hpi and 24 hpi, respectively. The cycle threshold of viral RNA varied among the target protein, VOC, and time of infection. The findings presented here demonstrate that all four VOCs evaluated caused ultrastructural changes in Vero-E6 cells, which were more prominent when infection occured with the Delta variant. viruscell virus SARSCoV2 SARSCoV SARS CoV 2 SARS-CoV- (VOCs 2021 transmissibility purpose VeroE6 VeroE Vero E6 E Vero-E RTPCR RT PCR RT‒PCR TEM (TEM 7 .

ABSTRACT Bell pepper is a globally important vegetable. The use of humic substances can enhance nutrient absorption efficiency, reducing the amounts of organic residues applied to the soil. Therefore, the objective of this study was to evaluate cattle manure rates combined with humic substance rates to increase bell pepper production. A randomized block design with four replicates was used, in a 4 × 3 factorial arrangement consisted of four cattle manure doses (8, 18, 28, and 38 Mg ha-1) and three humic substance doses (0, 8, and 12 kg ha-1). Humic substances affected bell pepper production characteristics; the highest mean fruit weight per plant (140.02 g) and fruit diameter (75.73 mm) were obtained when applying 8 Mg ha-1 of manure combined with 8 kg ha-1 of humic substances. Similarly, the greatest fruit length (80.94 mm) was found when applying 8 Mg ha-1 of manure combined with 12 kg ha-1 of humic substances. The highest yields (1.2 kg per plant and 60.14 Mg ha-1) were obtained when applying 38 Mg ha-1 of manure combined with 12 kg ha-1 of humic substances. The combination of humic substances and cattle manure increased the organic production of bell peppers under the edaphoclimatic conditions of the Semiarid region of Brazil. vegetable efficiency soil Therefore used (8 18 28 ha1 ha 1 0, 0 (0 ha1. . characteristics 140.02 14002 140 02 (140.0 g 75.73 7573 75 73 (75.7 mm ha- Similarly 80.94 8094 80 94 (80.9 1.2 2 (1. 6014 60 14 60.1 Brazil ( 140.0 1400 (140. 75.7 757 7 (75. 80.9 809 9 (80. 1.

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 Leprosy is a chronic infectious disease caused by the bacilli Mycobacterium leprae and Mycobacterium lepromatosis. In addition to humans, animals such as nine-banded armadillos and red squirrels are species naturally infected. The objective of this study was to investigate the presence of M. leprae and M. lepromatosis in non-volant small mammals of the order Didelphimorphia and Rodentia through Polymerase Chain Reaction (PCR) assay. During 2015 and 2018, field expeditions were carried out in three municipalities, covering biotic elements of the Amazon and Cerrado biomes, in the Mato Grosso State, Midwest of Brazil. A specific primer for repetitive sequences of the genomic DNA of M. leprae and M. lepromatosis targeting the RLEP and RLPM gene, respectively, was used to screen for these agents. The molecular detection of M. leprae DNA in the samples was 13.8%. M. lepromatosis was not detected.

Research to identify plant bioactive compounds led to the evolution of extraction methods. This study optimized ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE) to extract the flavonoids of Croton grewioides Baill. species contributing to characterize the polar extract profile and understand the antioxidant potential of these plant constituents. The use of experimental design and statistical treatments enabled the determination of the ideal conditions for each technique. The extracts of five accessions of C. grewioides were obtained under the optimized extraction conditions and were analyzed using ultra high-resolution mass spectrometry (FT-Orbitrap MS) operating at negative ionization mode for flavonoids detection. The accurate experimental mass obtained to the main compounds was used to attribute the molecular formula. Chemical structures of the main compounds detected were proposed using structure data bases. Chemometric analysis were performed with two FT-Orbitrap MS spectra samples using the identified metabolites and, the antioxidant activity data, showing that for this species the MAE was most effective in extracting the antioxidant compounds. It was possible to propose the structures for forty compounds in the C. grewioides extracts, demonstrating the excellent performance of the FT-Orbitrap MS in providing information on the chemical profile of polar compounds in plant extracts. methods ultrasoundassisted ultrasound assisted UAE (UAE microwaveassisted microwave (MAE Baill constituents technique C highresolution high resolution FTOrbitrap FT Orbitrap detection formula bases

RESUMO A salinidade é um dos grandes entraves na agricultura em regiões semiáridas, pois afeta os processos fisiológicos, crescimento e produção de diversas culturas. Assim, o uso de atenuadores do estresse salino é de extrema importância, pois permite o uso de águas salinas para fins agrícolas. Dentre estes, destacam-se os ácidos húmicos que promovem o crescimento e a absorção de água e nutrientes. Assim, o objetivo deste trabalho foi avaliar o efeito do ácido húmico sob o crescimento e a fisiologia de mudas de mamão irrigadas com água salina. O delineamento experimental utilizado foi em blocos casualizados com cinco níveis de condutividade elétrica (0,5; 1,15; 2,75; 4,35 e 5,0 dS m-1), e cinco concentrações de ácido húmico (0,5; 0,94; 2,0; 3,06 e 3,5 mL L-1). Foram avaliados o crescimento, trocas gasosas, índice de clorofilas e fluorescência da clorofila a. A irrigação com água de 4,9 dS m-1 e aplicação de 3,05 mL L-1 de ácido húmico proporcionou maior crescimento das mudas de mamoeiro. A irrigação de mudas de mamoeiro com alta salinidade (4,96 e 3,09 dS m-1) aliada à aplicação de 3,05 e 2,21 mL L-1 de ácido húmico proporcionou aumento da concentração interna de CO2, taxa de transpiração, eficiência instantânea do uso da água, eficiência de carboxilação e teor de clorofila b. O ácido húmico (3,5 mL L-1) atenua os efeitos deletérios da salinidade no mamoeiro, sendo capaz de aumentar o crescimento e melhorar o desempenho das mudas de mamão em salinidade moderada (4 dS m-1). semiáridas fisiológicos culturas Assim importância agrícolas estes destacamse destacam se nutrientes salina 0,5 05 0 5 (0,5 1,15 115 1 15 2,75 275 2 75 435 4 35 4,3 50 5, m1, m1 m , 0,94 094 94 2,0 20 306 3 06 3,0 3, L1.

ABSTRACT Salinity is one of the major obstacles to agriculture in semi-arid regions, as it affects the physiological processes, growth, and yield of numerous crops. Hence, the application of salt stress attenuators is of paramount importance, as it enables the use of saline water for agricultural purposes. Among these, humic acid promotes the growth as well as water and nutrient uptake of plants. To this end, the present study evaluated the effects of humic acid on the growth and physiology of Carica papaya seedlings irrigated with saline water. The experiment followed the randomized block design with five levels of electrical conductivity (0.5, 1.15, 2.75, 4.35, and 5.0 dS m-1) and five concentrations of humic acid (0.5, 0.94, 2.0, 3.06, and 3.5 mL L-1). Growth, gas exchange, chlorophyll content, and chlorophyll a fluorescence were evaluated. Irrigation with 4.9 dS m-1 water and application of 3.05 mL L-1 humic acid promoted the growth of papaya seedlings. Irrigation with high-salinity water (4.96 and 3.09 dS m-1) coupled with the application of 3.05 and 2.21 mL L-1 humic acid increased internal CO2 concentration, transpiration, instantaneous water use efficiency, carboxylation efficiency, and chlorophyll b content. Overall, humic acid (3.5 mL L-1) attenuated the deleterious effects of salt stress, promoting the growth and improving the performance of papaya seedlings under moderate salinity (4 dS m-1). semiarid semi arid regions processes crops Hence importance purposes these plants end 0.5, 05 0 5 (0.5 115 1 15 1.15 275 2 75 2.75 435 4 35 4.35 50 5. m1 m 094 94 0.94 20 2.0 306 3 06 3.06 3.

RESUMO Considerando a relevância do cajueiro e a limitação imposta pelo estresse salino em regiões semiáridas, o uso de alternativas capazes de mitigar os efeitos deletérios em decorrência da salinidade são de grande importância ao setor produtivo. O uso de plantas enxertadas, principalmente com porta-enxertos de materiais tolerantes, influencia no acúmulo de íons tóxicos nas folhas das mudas enxertadas. Assim, o objetivo deste trabalho foi avaliar características morfofisiológicas e concentração foliar de Na+, K+, Ca+2 de combinações de copa e porta-enxerto de cajueiro anão precoce, contrastantes à salinidade. O experimento foi realizado em delineamento inteiramente casualizado, com cinco repetições, tendo os tratamentos dispostos em arranjo fatorial de 4 × 3, correspondentes a quatro combinações de mudas enxertadas (auto-enxerto CCP 09/CCP 09, CCP 09/CCP 76, auto-enxerto CCP 76/CCP 76 e CCP 76/CCP 09) e a três concentrações de NaCl (0-controle, 50 e 100 mM L-1). Foram avaliados altura, número de folhas, área foliar, massa seca, índice de tolerância e concentração foliar de Na+, K+ e Ca+2 após 30 dias da aplicação das concentrações de NaCl. A combinação copa/porta-enxerto CCP 76/09 apresentou tolerância à salinidade de 50 mM L-1, devido ao aumento da área foliar e número de folhas. A combinação copa/porta-enxerto CCP 76/09 foi mais adequada, pois manteve a concentração foliar de K+ e o menor concentração de Na+.
ABSTRACT Considering the cashew tree’s relevance and the limitations imposed by salinity stress in semi-arid regions, the use of alternatives capable of mitigating the harmful effects due to salinity is of great importance to the production sector. The use of grafted plants, especially with rootstock made of tolerant materials, influences the accumulation of toxic ions in leaves of grafted seedlings. Thus, the objective of this work was to evaluate morphophysiological characteristics and leaf concentrations of Na+, K+ and Ca+2 of combinations of scion and rootstock of early dwarf cashew, contrasting in terms of salinity tolerance. The experiment was carried out in a completely randomized design with five replicates, in a 4 × 3 factorial arrangement, corresponding to four dwarf cashew scion/rootstock combinations (self-graft CCP 09, CCP 09/CCP 76, self-graft CCP 76, and CCP 76/CCP 09) and three NaCl concentrations (0, 50, and 100 mM L-1). Height, number of leaves, leaf area, dry matter, tolerance index and leaf concentrations of Na+, K+ and Ca+2 were evaluated after 30 days of application of NaCl concentrations. The scion/rootstock combination CCP 76/09 showed tolerance to 50 mM L-1, due to the increase of leaf area and number of leaves. The scion/rootstock combination CCP 76/09 was more suitable, as it kept the leaf K+ concentration and had the lowest Na+ concentration.

RESUMO No semiárido do Nordeste brasileiro as condições edafoclimáticas podem favorecer riscos de salinização do solo, principalmente quando se utiliza água de má qualidade para irrigação. Nesse contexto, técnicas que possibilitem melhorias nos rendimentos da cultura do melão em condições adversas, como a salinidade, são, portanto, de grande relevância para o setor produtivo. Logo, o objetivo deste estudo foi avaliar a eficácia do peróxido de hidrogênio (H2O2) na aclimatação do meloeiro submetido a diferentes níveis salinos na água de irrigação. Os tratamentos consistiram de duas condutividades elétricas da água de irrigação (0,3 e 5,0 dS m-1) e quatro concentrações de H2O2 (0, 5, 10 e 15 µmol L-1). O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 2 × 4, com quatro repetições e quatro plantas por parcela. O aumento da salinidade da água de irrigação reduz o crescimento, as trocas gasosas e a produção do meloeiro. No entanto, o H2O2, na concentração de 6,35 µmol L-1 proporcionou melhorias na fisiologia, crescimento e produção, além de reduzir os efeitos deletérios do estresse salino na produção de melão.
ABSTRACT In the semi-arid region of northeastern Brazil, soil and climate conditions can increase the risk of soil salinization, particularly when poor-quality water is used for irrigation. Therefore, techniques that improve the yields of melon culture under adverse conditions, such as salinity, are of great relevance to the production sector. The objective of this study was to evaluate the effectiveness of hydrogen peroxide (H2O2) in acclimatizing melon trees subjected to irrigation water with different salinity levels. The treatments consisted of irrigation water with two electrical conductivities (0.3 and 5.0 dS m-1) and four concentrations of H2O2 (0, 5, 10, and 15 µmol L-1). The experimental design used was randomized blocks, arranged in a 2 × 4 factorial scheme, with four replicates and four plants per plot. Increase in salinity of irrigation water reduced the growth, gas exchange, and production of melon plants. However, H2O2, at a concentration of 6.35 µmol L-1, yielded improvements in physiology, growth, and production, in addition to reducing the deleterious effects of saline stress on melon production.

Abstract The influence of refrigeration on the post-embryonic development of Chrysomya putoria larvae was evaluated, regarding its resistance in the logistics of storage and distribution in biotherapy. Previously sterilized larvae were submitted to four periods of storage under refrigeration (T1=12 h, T2=24 h, T3=48 h and T4=72 h) and control (without sterilization and refrigeration). Newly hatched larvae (0.200 g) were stored between 3 and 9ºC. After refrigeration, 40 neo-larvae (in triplicate) were transferred to 50 g of protein diet and incubated in an acclimatized chamber. There was a significant difference in the larval body mass (T1 and T2) and in the duration of larval, pupal and total development (T3 and T4). The sex ratios found in the four treatments did not differ from what was expected. Normality rates were 100% for all treatments. There was no significant difference between the Control, T1 and T2 treatments for larval, pupal and total viability. There was a significant difference between control (C) and T4 (larval viability), between C, T3 and T4 (pupa) and between C and T4 (total). C. putoria has resistance under refrigeration and storage of up to 56 h, presenting viability above 70% for use in biotherapy. postembryonic post embryonic evaluated biotherapy T1=12 T112 T 12 (T1=1 T224 24 T2=2 T348 48 T3=4 T472 72 T4=7 without refrigeration. . refrigeration) 0.200 0200 0 200 (0.20 9ºC ºC 4 neolarvae neo triplicate 5 chamber (T T4.

RESUMO A batata-doce é uma hortaliça alimentar básica para a população. Este trabalho objetivou-se avaliar o rendimento da batata-doce em resposta à adubação potássica com diferentes fontes e parcelamento. O trabalho foi conduzido na Universidade Federal da Paraíba, em Areia-PB. O delineamento experimental foi de blocos casualizados em arranjo fatorial 7 × 2, com sete épocas de aplicação (100% no plantio; 100% aos 30 dias após o plantio (DAP); 100% aos 60 DAP; 50% no plantio e 50% aos 30 DAP; 50% no plantio e 50% aos 60 DAP; 50% aos 30 e 50% aos 60 DAP; 33% no plantio 33% aos 30 e 33% aos 60 DAP) e duas fontes, cloreto e sulfato de potássio, com três repetições. As variáveis analisadas foram à massa fresca por planta, massa média de raízes comerciais, produção de raízes comerciais por planta, teor de K foliar, produtividades total e comercial de raízes. O cloreto e sulfato de potássio incrementaram a massa fresca da planta e a massa de raízes comerciais, respectivamente. As produtividades comerciais de raízes (25,16 e 22,28 Mg ha-1) foram superiores à média nacional (14,07 Mg ha-1), quando se forneceu K2O nas fontes sulfato e cloreto de potássio, respectivamente. O teor de K foliar ficou dentro do padrão para a cultura, sob adubação de cloreto e sulfato de potássio. A aplicação de sulfato de potássio proporciona maior rendimento de batata-doce. O cloreto e o sulfato de potássio, quando fornecidos em uma única aplicação, aumentam a produtividade total e comercial somente quando as plantas estão aos 60 DAP.
ABSTRACT Sweet potatoes are an important staple food for human consumption. This study evaluated sweet potato yield in response to potassium fertilization using different sources and splitting. It was conducted at the Universidade Federal da Paraíba, Areia-PB. A complete randomized block experimental design was used in a 7 × 2 factorial arrangement. The fertilization was split into seven treatments (100% after planting; 100% at 30 days after planting (DAP); 100% at 60 DAP; 50% after planting and 50% at 30 DAP; 50% after planting and 50% at 60 DAP; 50% at 30 DAP and 50% 60 at DAP; 33% after planting, 33% at 30 DAP, and 33% at 60 DAP). Two fertilization sources were used, namely potassium chloride and potassium sulfate, with three replicates. Plant fresh mass, mass of marketable roots, production of marketable roots per plant, leaf K concentration, total and marketable root yields were evaluated. Chloride and sulfate potassium efficiently increased the fresh mass of the plant and the mass of marketable roots, respectively. The marketable yield of the roots (25.16 and 22.28 Mg ha-1) was higher than the national average (14.07 Mg ha-1) when K2O was supplied in the sulfate and potassium chloride sources, respectively. The leaf K concentration remained within the standard levels for the crops under chloride and potassium sulfate fertilization. Potassium sulfate application results in higher sweet potato yields. When supplied in a single application, chloride and sulfate potassium increase the total and commercial yield only when the plants are at 60 DAP.
