ABSTRACT Copper is an essential element for beet; however, it needs to be made available in adequate quantities since this nutrient, which is a heavy metal, can cause toxicity to plants and/or humans. This study aimed to evaluate the agronomic performance of beet fertigated with copper in a semi-arid region of Brazil. Two experiments were carried out in complete randomized blocks, with five treatments (0, 1.5, 3.0, 4.0, and 6.0 kg ha-1 of copper) and four replicates. In 2019, the copper content was within the adequate range for beet. In 2021, fertigation with copper above 0.8 kg ha-1 led to contents in the phytotoxicity range, which may explain the reduction in total and tuberous root dry mass accumulation. Fertilization with copper increased marketable yield in 2019 (17.32 t ha-1 at the dose of 3.9 kg ha-1 of copper), while, in 2021, there was no fit of the equations. Copper fertilization altered the tuberous root pH but did not influence the other tuberous root quality components. Plants fertilized with copper accumulated more copper in the leaves than in the tuberous root, with a maximum accumulation of 6.0 kg ha-1 of copper in 2019 and 2021. Fertilization with 3.9 kg ha-1 suits soils with low copper content.
RESUMO O cobre é um elemento essencial à beterraba, no entanto, é necessário disponibilizá-lo em quantidade adequada uma vez que esse nutriente, que é um metal pesado, pode causar toxicidade às plantas e, ou, ao ser humano. Esta pesquisa teve como objetivo avaliar o desempenho agronômico de beterraba fertirrigada com cobre em uma região semiárida do Brasil. Foram conduzidos dois experimentos em delineados em blocos casualizados ao acaso, com cinco tratamentos (0, 1.5, 3.0, 4.5 e 6.0 kg ha-1 de cobre) e quatro repetições. Em 2019, o teor de cobre estava dentro da faixa adequada para a beterraba. Em 2021, a fertirrigação com cobre acima de 0.8 kg ha-1 proporcionou teores na faixa de fitotoxicidade, o que pode explicar a redução no acúmulo de massa seca total e de raízes tuberosas. A adubação com cobre aumentou a produtividade comercial em 2019 (17.32 t ha-1 na dose de 3.9 kg ha-1 de cobre) enquanto que, em 2021, não houve modelo ajustado. A adubação alterou o pH da raiz tuberosa, mas não influenciou nos demais atributos de qualidade pós-colheita da raiz tuberosa. Plantas adubadas com cobre acumularam mais cobre nas folhas do que na raiz tuberosa, com máxima acumulada em 2019 e em 2021, na dose 6.0 kg ha-1 de cobre. A adubação com 3.9 kg ha-1 é adequada para solos com baixo teor de cobre.

Food additives are chemical substances added to improve organoleptic characteristics, in this context, there are several synthetic dyes, such as sunset yellow, tartrazine, erioglaucine, allura red, indigo carmine, and new coccine, that can also be identified through different analytical techniques such as infrared spectroscopy, UV-Vis spectrophotometry, high performance liquid chromatography with diode array detector and mass spectrometry. Therefore, the objective of this work was to compare methods developed for different analytical techniques, in order to identify the one that presents greater efficiency in certain applications. For this, the patterns of the dyes were analyzed, as well as their mixtures and foods that had them. As a result, the CLAE-DAD presents excellent selectivity and linearity of the calibration curves, but it presents higher LD and LQ values when compared to the UV-Vis, in turn the infrared provides information regarding functional groups and bonds. Mass spectrometry showed great capabilities in identifying the molecular formula and better selectivity in the absence of the erioglaucine dye. It is not feasible to indicate the best or worst analytical approach, but it is possible to point out which one is more suitable for each application. Regarding the quantification capacity, chromatography and UV-Vis are good alternatives, but in mixtures containing more than one dye, CLAE-DAD is more suitable due to the better selectivity. Regarding the identification capacity, mass spectrometry, especially FT-ICR MS, is the most appropriate technique to propose molecular formulas due to its high resolution and mass accuracy. The advantage of FTIR was the easier sample preparation, being able to analyze the dyes in the solid state.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Over the years, laser-induced breakdown spectroscopy (LIBS) has been reported in the literature as an alternative to traditional methods of analysis, becoming well established among spectroanalytical techniques. LIBS is a technique widely used for qualitative approaches; however, it is necessary considerable effort for use in quantitative analysis, mainly due to severe matrix effects. These limitations make it difficult to broaden the application of LIBS in quantitative analysis. In this sense, this review discusses recent advances in calibration strategies applied in LIBS for minimizing matrix effects and enabling determination with satisfactory accuracy and precision. Applications, advantages, and limitations of the calibration strategies, such as matrix-matching calibration (MMC), internal standardization (IS), standard addition (SA), multi-energy calibration (MEC), one-point gravimetric standard addition (OP GSA), one-point and multi-line calibration (OP MLC), slope ratio calibration (SRC), two-point calibration transfer (TP CT), single-sample calibration (SSC), multiple linear regression (MLR), principal component regression (PCR), partial least squares (PLS) and artificial neural networks (ANN) are discussed.

The essential oil of Cymbopogon nardus, citronella, has been extensively studied. However, the chemical and biological properties of the ethanolic extract (EE) of C. nardus have not been evaluated. The aim of this study was to characterize the chemical composition of the EE of C. nardus and its active fraction (FrD). Moreover, the cytotoxic and antifungal properties of these extracts against Candida species with different resistance profiles to conventional drugs were evaluated. The compounds identified in EE were mono-C- and di-C-glycosyl flavones and phenylpropanoid glycosides. Phenylpropanoid glycosides were identified in FrD. EE showed antifungal activity, with minimum inhibitory concentration (MIC) values ranging from 62. 5 to 500 µg mL-1. FrD was more effective against C. glabrata, as evidenced by the lowest MIC value (15. 6 µg mL-1). EE inhibited yeast growth similar to amphotericin-B, as demonstrated by similar time-kill curves. EE inhibited C. albicans hyphae formation and mature biofilm of C. albicans, C. krusei and C. parapsilosis. The results of the chemical and biological analyses of EE and its fractions provided novel information and may contribute to control of infections caused by Candida species.

Our study aimed at the development of a method based on ultra-performance liquid chromatography coupled to mass spectrometry (UPLC-ESI-MS) using selected ion monitoring for the simultaneous quantitation of the alkaloids galantamine, pseudolycorine, sanguinine and narciclasine in Amaryllidaceae species (Hippeastrum elegans, Habranthus cf. irwinianus, Hymenocallis littoralis and Griffinia nocturna). The alkaloids were extracted from dried and ground bulbs (100 mg) using liquid-liquid microextraction followed by solid phase extraction in cation exchange cartridges. The quantification method showed good linearity (correlation coefficient, R ≥ 0.9968) and selectivity for a run time of 10 min. All values were within the acceptable limits for recovery (87.5-96.2%), interday (coefficient of variation, CV%, 1.3-8.4%) and intraday precision (CV% 5.7-8.1%), except narciclasine (70%). The limits of detection and quantification were 5-100 and 20-350 ng mL-1, respectively. Our method demonstrated to be rapid, sensitive and reliable, therefore appropriate for being employed in the prospection of new source of galantamine and other alkaloids.

This review attempts to present a broad view of the technique laser-induced breakdown spectroscopy (LIBS), since its origin, fundamentals, sample preparation strategies, use of chemometric tools for data processing, the advantages and limitations with regard to qualitative and quantitative analysis, aplications and future trends as an analytical technique that is in consolidation in analytical chemistry. LIBS is a rapid and versatile, which is able of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and enables remote analysis. The advancement of the LIBS applications in the areas of agriculture, environmental, food, biological/pharmaceutical, forensic, metallurgy and electronic waste were discussed in detail in this review. We consider that this review will be an important tool concerning dissemination of the LIBS, mainly for audience of undergraduate courses, and disciplines related to instrumental analysis.

ABSTRACT This study presents registers of Helicoverpa armigera (Hübner) occurrence to assess its spatial and temporal distribution in Brazil. We used data from collections, especially from the Southern Region, systematic collections in Rio Grande do Sul, occasional collections of caterpillars and adults in different regions of Brazil, as well as literature registers. We conclude that the introduction of H. armigera in Brazil probably occurred before October 2008. We also register that in August 2012 H. armigera was already present from the extreme southern part (Rio Grande do Sul) to the extreme northern part (Amapá) of Brazil.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

OBJETIVOS: Avaliar a prevalência e descrever alterações da morfologia genital em recém-nascidos em duas maternidades-escola de gestão pública. MÉTODOS: Estudo caso/controle, descritivo, transversal. Utilizou-se protocolo clínico para avaliação da morfologia genital de 2.916 recém-nascidos entre 19/04/2010 e 18/04/2011. O grupo controle foi formado pelos nascimentos sem anormalidades morfológicas ocorridos no dia e na maternidade em que o caso foi detectado. Teste exato de Fisher foi utilizado para análises de variáveis categóricas, e de Kruskal-Wallis, para igualdade de médias. RESULTADOS: Foram detectados 29 recém-nascidos com anormalidade genital (1:100). A maioria (93,2%) foi examinada nos três primeiros dias de vida e apresentava apenas uma anormalidade. Os defeitos morfológicos compreenderam: ambiguidade genital evidente (1/29), fusão posterior de grandes lábios (1/29), micropênis (2/29), clitoromegalia (6/29), criptorquidia bilateral (6/29), hipospádia (9/29) e defeitos combinados (4/29) casos. Em apenas um caso os campos da Declaração de Nascido Vivo foram preenchidos corretamente. Prematuridade foi observada em 13/29, sendo esta a única variável estatisticamente associada à presença de anormalidade genital. Oito casos aderiram à proposta de investigação complementar, entre os quais três tiveram diagnóstico clínico de distúrbio da diferenciação do sexo. CONCLUSÕES: Evidenciou-se alta prevalência, subdiagnóstico e sub-registro de defeitos genitais nas maternidades estudadas. Os resultados reforçam a importância do exame cuidadoso de recém-nascidos com o objetivo de identificar anormalidades genitais sutis que podem compor o quadro clínico de distúrbio da diferenciação do sexo.
OBJECTIVES: To assess the prevalence of genital abnormalities among neonates in two public maternity-schools. METHODS: Case-control, cross-sectional descriptive study. Genital morphology of 2,916 neonates was assessed using a clinical protocol between 04/19/2010 and 04/18/2011. Control group included neonates without birth defects, born at the same maternity unit and in the same day in which a case was identified. Fisher and Kruskal-Wallis tests were used for statistics. RESULTS: The study identified 29 (1:100) neonates with genital abnormalities. Most of them were examined within 3 days of life and presented only one genital defect. Morphological abnormalities comprised: genital ambiguity (1/29), fusion of labia majora (1/29), micropenis (2/29), enlarged clitoris (6/29), hypospadia (9/29), and combined defects (4/29). Only one case reported the genital abnormality in the statement of live birth correctly. Prematurity occurred in 13/29 cases and was the only variable statistically associated with genital defects. Eight cases agreed on the complementary investigation of the genital defect, among which three were diagnosed with disorder of sex development. CONCLUSIONS: There is a high prevalence of genital abnormalities in the maternity units included in the present study and most cases are under-diagnosed and under-reported. Our results reinforce the importance of a careful examination of genital morphology in neonatal period towards the recognition of minor defects that can be clinical features of a disorder of sex development.

OBJETIVOS: Analisar a evolução de famílias com epilepsia de lobo temporal mesial familiar (ELTMF). METODOLOGIA: Seguimento prospectivo de 64 pacientes com ELTMF e 37 membros assintomáticos pertencente a 28 famílias. RESULTADOS: A média de seguimento dos pacientes com ELTMF foi de 93,4 ± 15,8 meses. Na avaliação inicial os pacientes foram divididos em benignos (n = 29), remissão (n = 28) e refratários (n = 7). Na última visita disponível, 41,4% dos pacientes com ELTMF benigna permaneceram classificados como benignos, 20,7% tornaram-se refratários e 37,9% entraram em remissão. No grupo em remissão, 75% permaneceram livres de crise, 21,4% foram classificados como benignos e um faleceu (3,6%) de causa não relacionada à epilepsia. Todos pacientes refratários permaneceram refratários. Em relação aos assintomáticos 10,8% evoluíram com crises. A média de seguimento dos assintomáticos foi de 76,0 ± 21,2 meses. CONCLUSÃO: O seguimento prospectivo de mais de 7 anos de pacientes com ELTMF revelou que é improvável ocorrer controle de crises no grupo refratário. No grupo benigno é muito provável que estes indivíduos entrem em remissão ou permaneçam com evolução benigna. A maioria dos pacientes do grupo em remissão permaneceu em remissão e nenhum se tornou refratário. Em relação aos assintomáticos a probabilidade de apresentar uma crise no decorrer de aproximadamente 6 anos foi maior que o observado na população geral.
OBJECTIVE: To analyze seizure outcome in individuals with familial mesial temporal lobe epilepsy (FMTLE). METHOD: We followed prospectively 64 individuals with FMTLE and 37 asymptomatic individuals belonging to 28 families. RESULTS: Patients with FMTLE had a mean follow up was 93.4 ± 15.8 months. At baseline they were divided in benign (n = 29), remission (n = 28) and refractory (n = 7). At last follow up visit 41.4% patients with benign FMTLE remained classified as benign, 20.7% became refractory and 37.9% were in remission. In the subgroup of FMTLE in remission 21 75% remained without seizures; 21.4% were classified as benign FMTLE, and one died (3.6%) from cause unrelated to epilepsy. All refractory patients remained refractory. From the asymptomatic group, 10.8% became symptomatic (FMTLE). The mean follow up was 76.0 ± 21.2 months. CONCLUSION: Prospective follow up of more than 7 years in patients with FMTLE revealed that it is unlikely to achieve seizure control in those with refractory seizures. Patients with diagnose of more benign forms of FMTLE for more than one year are likely to either remit or remain under well controlled seizures. The majority of patients who had achieved seizure remission remained seizure-free and none became refractory. Asymptomatic individuals had a greater probability to have seizures compared to the general population in a 6 year period of follow up.

A kinetic formulation developed to analyze wave propagation in dusty plasmas, which takes into account the variation of the charge of the dust particles due to inelastic collisions with electrons and ions, is utilized to study the propagation and damping of electrostatic waves with wave number exactly parallel to the external magnetic field and Maxwellian distributions for the electrons and ions in the equilibrium. It is shown that, due to the presence of the dust, the damping of Langmuir waves in the region of large wavelengths is increased as compared to conventional Landau damping. Langmuir waves in the occurrence of collisional charging of dust particles also feature weak damping for small wavelengths, which vanishes if the effect of collisional charging of the dust particles is neglected in the dispersion relation. It is also shown that the damping of ion-acoustic waves is modified by the presence of the dust, and that some damping effect due to the dust particles remains even if the effect of collisional charging of dust particles is neglected in the dispersion relation.

Determinou-se a eficiência de inseticidas contra Sitophilus oryzae (L.) (Coleoptera: Curculionidae) e Rhyzopertha dominica (Fab.) (Coleoptera: Bostrichidae), em arroz (Oryza sativa) armazenado tratado. Os tratamentos foram feitos usando um pulverizador equipado com bico pneumático, sendo utilizado para todos os tratamentos 5 ml de calda/kg de arroz, exceto na testemunha tratada apenas com água. Para cada tratamento foram usados 1,2 kg de arroz, que foram tratados em sacos plásticos e em seguida acondicionados em sacos de ráfia e armazenados em sala climatizada (25 ± 2ºC). Quinze dias após os tratamentos, 200 g de arroz de cada um dos tratamentos, foram infestados com 40 insetos adultos de cada espécie, sendo este procedimento repetido a cada 30 dias. A contagem do número de insetos mortos foi realizada 15 dias após cada infestação aos 30, 60, 90, 120, 150 e 180 dias após a aplicação dos inseticidas. Após 180 dias da aplicação o Sumigran plus (15 e 20 ml/t) foi eficiente no controle de S. oryzae. No controle de R. dominica, até os 180 dias após a aplicação, foram eficientes: Sumigran plus (15 e 20 ml/t), Sumigran ® + Sumidan ® (15 + 15 e 20 + 20 ml/t), Sumigran ® + K-Obiol ® (15 + 15 ml/t).
The efficacy of insecticides against Sitophilus oryzae (L.) (Coleoptera: Curculionidae) and Rhyzopertha dominica (Fab.) (Coleoptera: Bostrichidae) exposed to treated stored rice (Oryza sativa) was tested. The insecticides were applied using a propelling air atomizer (5 ml of mixture/kg of rice); for the control only water was used. For each treatment 1.2 kg of stored rice, were treated in plastic bags and stored in raffia bags in a climatized room (25 ± 2ºC). Fifteen days after treatment, 200 g of the treated rice, from each treatment, were infested with 40 adults of each species. This procedure was repeated every 30 days. The number of dead insects was recorded 15 days after infestations, at 30, 60, 90, 120, 150 and 180 days after the insecticide application. Sumigran plus (15 and 20 ml/t) was effective against S. oryzae until 180 days after treatment. Sumigran plus (15 and 20 ml/t), Sumigran ® + Sumidan ® (15 + 15 and 20 + 20 ml/t), Sumigran ® + K-Obiol ® (15 + 15 ml/t), were effective against R. dominica up to 180 days after treatment.
