RESUMO O potássio é um dos nutrientes mais importantes para o algodoeiro, sendo um elemento que participa de muitas funções fisiológicas na planta. Além disso, sua adequada disponibilidade favorece melhor desempenho produtivo à cultura. Logo, objetivou-se avaliar nesta pesquisa os componentes agronômicos em cultivares de algodão naturalmente colorido adubadas com doses de potássio no Semiárido brasileiro. Para isto, dois experimentos foram conduzidos na Fazenda Experimental Rafael Fernandes, localizada no município de Mossoró, RN, nos períodos de julho a novembro de 2019 e julho a novembro de 2021. O delineamento experimental foi o de blocos casualizados, arranjados em parcelas subdivididas, com quatro repetições. Nas parcelas, foram alocadas as doses de potássio (0, 60, 120, 180 e 240 kg ha-1 de K2O); e, nas subparcelas, as quatro cultivares de algodão naturalmente colorido (BRS Rubi, BRS Safira, BRS Verde e BRS Topázio). As cultivares de algodão colorido respondem à adubação potássica em função das condições edafoclimáticas as quais estão expostas. A cultivar BRS Topázio obteve maior produtividade e porcentagem de fibra nas duas safras de cultivo, destacando o seu potencial para a região. A dose de 240 kg ha-1 de K2O aumentou a produtividade do algodão colorido, em cultivo de segunda safra. As cultivares BRS Safira, BRS Rubi e BRS Verde foram pouco produtivas. algodoeiro planta disso cultura Logo objetivouse objetivou se brasileiro isto Fernandes Mossoró RN 201 2021 casualizados subdivididas repetições 0, 0 (0 60 120 18 24 ha1 ha 1 ha- KO K K2O) subparcelas Safira Topázio. .

ABSTRACT Potassium is one of the most important nutrients for the cotton plant, being an element that participates in many physiological functions. In addition, its adequate availability favors better production performance of the crop. Therefore, the objective of this study was to evaluate the agronomic components in naturally colored cotton cultivars fertilized with potassium doses in the Brazilian semiarid region. For this, two experiments were conducted at Rafael Fernandes Experimental Farm, located in the municipality of Mossoró, RN, from July to November 2019 and July to November 2021. The experimental design was randomized blocks, arranged in split plots, with four repetitions. Potassium doses (0, 60, 120, 180, and 240 kg ha-1 of K2O) were allocated in the plants; and four naturally colored cotton cultivars (BRS Rubi, BRS Safira, BRS Verde, and BRS Topázio) were allocated in the subplots. Colored cotton cultivars respond to potassium fertilization depending on the edaphoclimatic conditions to which they are exposed. BRS Topázio cultivar had higher lint cotton yield and fiber percentage in both growing seasons, highlighting its potential for the region. The dose of 240 kg ha-1 of K2O increased the yield of colored cotton, in second crop cultivation. The cultivars BRS Safira, BRS Rubi, and BRS Verde were not very productive. plant functions addition Therefore region Farm Mossoró RN 201 2021 blocks plots repetitions 0, 0 (0 60 120 180 24 ha1 ha 1 ha- KO K O plants Rubi Safira subplots exposed seasons cultivation productive 20 202 ( 6 12 18 2

RESUMO O fósforo (P) é um nutriente mineral primordial para as plantas, pois está diretamente ligado a processos fisiológicos e bioquímicos essenciais para a manutenção das plantas, podendo influenciar na produção e na qualidade final do produto. Além disso, o P favorece o bom desenvolvimento radicular, o que pode beneficiar a cultura da batata-doce. Assim, o objetivo do trabalho foi avaliar a influência de doses crescentes de P na produção e qualidade física da batata-doce em duas épocas de cultivo em ambiente semiárido. Os experimentos foram realizados de abril a agosto de 2021 (época 1) e de dezembro de 2021 a abril de 2022 (época 2) na Fazenda Experimental Rafael Fernandes - UFERSA, Mossoró, RN, BR. O delineamento utilizado foi em blocos casualizados, com quatro repetições. Os tratamentos consistiram de cinco doses de P (0; 60; 120; 180 e 240 kg ha-1 de P2O5) via fertirrigação e testados em batata -doce cultivar Paraná. Após a colheita das raízes, foram avaliados o número e a produtividade de raízes (comerciais, não comerciais e totais), a massa média e a porcentagem de raízes comerciais. Raízes comerciais foram avaliadas quanto à firmeza, elasticidade e tempo de cozimento. As doses de P influenciaram as características de produção, principalmente na dose de 60 kg ha-1 de P2O5, o que promoveu aumentos na produtividade de raízes comerciais. As doses de P promoveram a redução da firmeza nas duas épocas de cultivo. A dose de 180 kg ha-1 de P2O5 proporcionou menor tempo de cozimento para a segunda época de cultivo.

ABSTRACT Phosphorus (P) is a primordial mineral nutrient for plants, as it is directly linked to physiological and biochemical processes essential for plant maintenance, and can influence the production and final quality of the product. Furthermore, P favors good root development, which can benefit sweet potato crop. Thus, the objective of the work is to assess the influence of increasing doses of P on the production and physical quality of sweet potatoes in two growing seasons in a semi-arid environment. The experiments were carried out from April to August 2021 (season 1) and from December 2021 to April 2022 (season 2) at the Rafael Fernandes Experimental Farm - UFERSA, Mossoró, RN, BR. The design was randomized blocks, with four replications. The treatments consisted of five doses of P (0; 60; 120; 180 and 240 kg ha-1 of P2O5) via fertigation and tested on the sweet potato cultivar Paraná. After harvesting the roots, the number and yield of roots (commercial, non-commercial and total), the average mass and the percentage of commercial roots were evaluated. Commercial roots were evaluated for firmness, elasticity and cooking time. The P doses influenced the production characteristics, mainly at the dose of 60 kg ha-1 of P2O5, which promoted increases in the yield of commercial roots. The doses of P promoted the reduction of firmness for both growing seasons. A dose of 180 kg ha-1 of P2O5 led to the shortest cooking time for the second growing season.

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 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.

The coronavirus pandemic has been causing damage to many nations, as public and private health systems deteriorate by the increasing demand. Some infected patients have culturable severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) even though not presenting any symptoms, and therefore, are probably able to transmit it. Correctly diagnosing and isolating infected patients is an important step towards preventing new infections. Current diagnostic methods rely mainly on reverse transcription quantitative polymerase chain reaction (RT-qPCR). Methods such as reverse transcription loop-mediated isothermal amplification (RT-LAMP) have risen as viable alternatives, as they are cheaper and require less infrastructure, they have the potential to be applied in low-resource scenarios and even at point-of-care. Here we report a colorimetric RT LAMP assay capable of detecting SARS-CoV-2 in ribonucleic acid (RNA) from saliva. In some cases, the test was able to detect viral RNA before symptom onset and even in a self-reported asymptomatic carrier. It had a limit of detection of 300 copies per reaction and showed a sensitivity of 80%, a specificity of 100%, a general accuracy of 99.59%, and a Cohen’s kappa of 0.887. The possibility of detecting positive cases even before the clinical manifestation shows great potential and can contribute to controlling the pandemic.

This work reports the synthesis, structure and catalytic activity of a novel ruthenium(II) complex, [RuCl(dppb)(44bipy)(4-pic)]PF6 (where dppb = 1,4-bis(diphenylphosphine)butane; 44bipy = 4,4’-dimethyl-2,2’-dipyridyl; 4-pic = 4-picoline). The molecular structure and catalytic activity were studied by Fourier transform infrared (FTIR), UV-Vis and nuclear magnetic resonance (NMR) spectroscopies, cyclic voltammetry, and X-ray crystallography, while the electronic structure was investigated by density-functional theory (DFT) and time dependent DFT (TD-DFT) methods. Electrochemical studies showed the substitution of the chlorido ligand from the precursor by the 4-pic ligand, exhibiting the RuII/RuIII process at 1.21 V. The structure of the compound was optimized using DFT simulations and showed data similar to the X-ray structure. The UV-Vis absorption spectrum showed a good agreement with TD-DFT simulations. The highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) energies were determined at the Becke, 3-parameter, Lee-Yang-Parr (B3LYP) level. The study of the catalytic activity in the transfer hydrogenation of ketones by the 1H NMR showed efficient transfer hydrogenation reaction at 60 ºC, employing acetophenone as substrate and resulting in a high conversion. The formation of two ruthenium-hydride species was observed.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

OBJECTIVES: To determine the effects of three sessions of a passive stretching exercise protocol on the muscles of elderly female rats. METHODS: The effects of the stretching exercises on the soleus muscle were analyzed using immunohistochemistry [tissue inhibitors of matrix metalloproteinases (TIMP), the tumor necrosis factor-alpha (TNF-α), and the gene expression levels using real-time PCR of the transforming growth factor-beta 1 (TGF-β1), collagen type 1 (COL1), and collagen type 3 (COL3)]. Fifteen 26-month-old female Wistar rats were randomly divided into two groups, namely, Stretching (SG, n=8) and Control (CG, n=7). The passive mechanical stretching protocol consisted of a set of 4 1-minute repetitions, with 30 seconds between each repetition (total treatment of 4 minutes), three times a week for 1 week. RESULTS: Immunohistochemical analysis revealed an increase of 71.4% in the TNF-α (p=0.04) gene expression levels for the SG and a 58% decrease in the TGF-β1 gene expression levels (p=0.005) in the SG compared to that in the CG. No significant differences were observed between the groups for the immunostaining of TIMP-1 or the gene expression levels of COL1 and COL3. CONCLUSION: Three sessions of static stretching reduced the gene expression level of TGF-β1, which, owing to its anti-fibrotic role, might contribute to the remodeling of the intramuscular connective tissue of the aging muscle. In addition, immunostaining revealed that TNF-α levels increased in the aging muscle tissue in response to stretching, indicating its effect on stimulating extracellular matrix degradation. These outcomes have important clinical implications in reinforcing the use of stretching exercises in the elderly, considering that the aging muscle presents an infiltration of connective tissue.

A thiourea derivative, N-[(phenylcarbonyl)carbamothioyl]benzamide, was synthesized and characterized by elemental analysis, thermal analysis, spectroscopic methods (Fourier transform infrared (FTIR), UV-Vis, Raman, matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF), tandem mass spectrometry (MS/MS) and nuclear magnetic resonance (NMR)) and quantum-chemical calculations. The synthetic route was simple and efficient, conducted just by one-step and no purification step was needed. The compound crystallizes in a non-centrosymmetric orthorhombic crystal system with a P21 21 21 space group, with a= 5.06220(10) Å, b= 11.8623(3) Å, c= 21.9682(8) Å. The molecular conformation of the solid is stabilized by the N-H···O intramolecular hydrogen bond, which was present in the X-ray structure and was also found in the optimized geometry. The theoretical analysis showed that this strong interaction remains even when molecules are solvated, i.e., the rotation barrier and the hydrogen bond strength are greater than the solvent stabilization energy. In addition to this hydrogen bond effect, the relative position of phenyl groups has a certain influence on the chemical behavior of this thiourea and probably for other phenylthioureas.

Mating disruption is a technique that uses synthetic copies of sex pheromones to control insect pests. We aimed to control Oriental fruit moth (OFM) Grapholita molesta (Busck) (Lepidoptera: Tortricidae) with formulations of SPLAT Grafo (SG) and SPLAT Grafo Attract and Kill (SGAK) in small (1 ha) apple (Malus domestica Borkh.) orchards. Our experiment was conducted in a commercial orchard with ’Gala’ trees (spacing 1.5 x 4.5 m) in Vacaria, Rio Grande do Sul State, Brazil. We evaluated the effect of four treatments on G. molesta population densities: a) SG at 1 kg ha-1 (300 point sources of 3.3 g each), b) SGAK at 1 kg ha-1 (1000 point sources of 1 g each), c) insecticides as recommended by Integrated Apple Production (IAP), and d) untreated control (no treatment). Specialized Pheromone and Lure Application Technology (SPLAT) treatments were applied on 1 August 2004 and reapplied after 120 d (1 December 2004). The treatment effect was evaluated by weekly counts of males captured in Delta traps baited with commercial synthetic sex pheromone lures (eight traps per treatment). We assessed fruit damage caused by G. molesta in eight replicates of 200 fruits each on 26 October, 30 November 2004, and 5 and 31 January 2005. Applying 1 kg ha-1 of SG and SGAK in August and December 2004 significantly reduced the number of male moths caught in Delta traps. Damage to fruits at harvest, however, did not differ significantly from the control. This indicates a decline in the efficacy of mating disruption when SG and SGAK are used to protect small areas (1 ha) under high Oriental fruit moth pressure.

OBJETIVO Revisar os aspectos históricos, epidemiológicos, etiológicos, gestacionais, diagnósticos e prognósticos da gemelaridade imperfeita. FONTES DE DADOS: Pesquisaram-se artigos científicos nos portais PubMed, SciELo e Lilacs, utilizando-se os descritores "conjoined twins", "multiple pregnancy", "ultrasound", "magnetic resonance imaging" e "prognosis". A pesquisa não se delimitou a um período específico de tempo. Complementou-se a revisão com material bibliográfico presente em livros. SÍNTESE DOS DADOS A descrição de gêmeos fusionados é lendária. Estima-se que a frequência seja em torno de 1/45.000-200.000 nascidos vivos. São gêmeos monozigóticos, monocoriônicos e usualmente monoamnióticos, que podem ser classificados de acordo com o local de fusão mais proeminente, com a simetria entre os gêmeos fusionados ou com a estrutura de compartilhamento. Pode-se realizar o diagnóstico ainda no período pré-natal ou depois do nascimento por meio de diferentes técnicas, como ultrassonografia, ressonância magnética e ecocardiografia. Tais exames são de suma importância para o entendimento da anatomia do feto/criança, bem como para a determinação do prognóstico e do plano cirúrgico. CONCLUSÕES Embora a gemelaridade imperfeita seja uma condição rara, o diagnóstico pré-natal é muito importante para avaliar o local de fusão e sua complexidade. Logo, a avaliação dessas crianças deve ser multidisciplinar, envolvendo principalmente obstetras, pediatras e cirurgiões pediátricos. Contudo, algumas decisões podem se constituir em verdadeiros dilemas éticos, nos quais diferentes aspectos devem ser discutidos e analisados juntamente com a equipe de saúde e a família da criança.
OBJECTIVE To review the history, epidemiology, etiology, gestational aspects, diagnosis and prognosis of imperfect twinning. DATA SOURCES Scientific articles were searched in PubMed, SciELO and Lilacs databases, using the descriptors "conjoined twins", "multiple pregnancy", "ultrasound", "magnetic resonance imaging" and "prognosis". The research was not delimited to a specific period of time and was supplemented with bibliographic data from books. DATA SYNTHESIS: The description of conjoined twins is legendary. The estimated frequency is 1/45,000-200,000 births. These twins are monozygotic, monochorionic and usually monoamniotic. They can be classified by the most prominent fusion site, by the symmetry between the conjoined twins or by the sharing structure. The diagnosis can be performed in the prenatal period or after birth by different techniques, such as ultrasound, magnetic resonance imaging and echocardiography. These tests are of paramount importance for understanding the anatomy of both fetuses/children, as well as for prognosis and surgical plan determination. CONCLUSIONS Although imperfect twinning is a rare condition, the prenatal diagnosis is very important in order to evaluate the fusion site and its complexity. Hence, the evaluation of these children should be multidisciplinary, involving mainly obstetricians, pediatricians and pediatric surgeons. However, some decisions may constitute real ethical dilemmas, in which different points should be discussed and analyzed with the health team and the family.
OBJETIVO Revisar los aspectos históricos, epidemiológicos, etiológicos, gestacionales, diagnósticos y pronósticos de la gemelización imperfecta. FUENTES DE DATOS Se buscaron artículos científicos en los portales PubMed, SciELO y Lilacs, utilizando los descriptores "conjoinedtwins", "multiplepregnancy", "ultrasound", "magneticresonanceimaging" y "prognosis". La investigación no se limitó a un periodo determinado y específico de tiempo. Se complementó la revisión con material bibliográfico presente en libros. SÍNTESIS DE LOS DATOS La descripción de gemelos fusionados es legendaria. Se estima que la frecuencia sea alrededor de 1/45.000-200.000 nacidos vivos. Son gemelos monocigóticos, monocoriónicos y usualmente monoaminióticos, que pueden clasificarse conforme al local de fusión más prominente, con la simetría entre los gemelos fusionados o con la estructura de compartimiento. Se puede realizar el diagnóstico todavía en el periodo prenatal o después del nacimiento mediante diferentes técnicas, como ultrasonografía, resonancia magnética y ecocardiografía. Esos exámenes son de suma importancia para el entendimiento de la anatomía del feto/bebé, así como para la determinación del pronóstico y del plan quirúrgico. CONCLUSIONES Aunque la gemelización imperfecta sea una condición rara, el diagnóstico prenatal es muy importante para evaluar el local de fusión y su complexidad. Así, la evaluación de esos bebés debe ser multidisciplinaria, implicando principalmente a obstetras, pediatras y cirujanos pediátricos. Sin embargo, algunas decisiones pueden constituirse en verdaderos dilemas éticos, en los que distintos aspectos deben discutirse y analizarse juntamente con el equipo de salud y la familia del niño.

Neste trabalho, propõe-se a determinação de fenol e o-cresol por análise por injeção em fluxo (FIA) com detecção espectrofotométrica, utilizando a reação com 4-aminoantipirina, a fim de quantificar essas espécies em extratos de solo. Após otimização das condições por planejamento fatorial, constatou-se uma maior frequência de amostragem em comparação com o método convencional, bem como valores de recuperação, limites de detecção e de quantificação comparáveis para ambos os métodos. Tais aspectos sugerem que esse método pode ser uma alternativa viável para a determinação de compostos fenólicos em extratos de solos.
Phenol and o-cresol determination by flow injection analysis (FIA) with spectrophotometric detection, employing the 4-aminoantipyrine reaction, is proposed in this work in order to quantify these species in soil extracts. The method was improved by a factorial planning, being verified a higher sampling rate in comparison with the conventional method, and recovery values, limits of detection and quantification similar for both methods. These aspects suggest this method as a feasible alternative for phenolic compound determinations in soil extracts.

O objetivo deste trabalho foi a geração de um inventário dos dados de datação de radiocarbono obtidos de sedimentos do Embaiamento de São Paulo (Margem Continental Superior do Sul do Brasil) e analisar os dados em termos de processos sedimentares quaternários e taxas de sedimentação. Um total de238 datações ao radiocarbono de materiais coletados com autilização de procedimentos amostrais diferentes foi considerado neste trabalho. As taxas de sedimentação variaram de menor que 2 a 68 cm.kyr-1. As taxas de sedimentação mais altas foram encontradas em um sistema costeiro de baixa energia (tipo ría), bem como nas zonas de ressurgência de Santa Catarina e Cabo Frio. As taxas mais baixas foram encontradas na plataforma externa e talude superior. Nossos resultados confirmam a forte dependência do sistema de correntes de plataforma, com ênfase no aporte terrígeno oriundo do Rio daPrata, transportado através da Corrente Costeira do Brasil, e da dinâmica da Corrente do Brasil - Corrente de Contorno Intermediária (CB-CCI) nos processos sedimentares. Pelo menostrês indicadores de paleo-níveis marinhos foram encontrados a 12200 anos AP (idade radiocarbônica convencional) (103 metros abaixo do nível do mar atual - manm), 8300-8800 cal anos AP (13 manm) e 7700-8100 cal anos BP (6 manm).
The aim of this work was to generate an inventory of the data on radiocarbon datings obtained from sediments of the São Paulo Bight (southern Brazilian upper margin) and to analyze the data in terms of Late Quaternary sedimentary processes and sedimentation rates. A total of 238 radiocarbon datings from materials collected using differents ampling procedures was considered for this work. The sedimentation rates varied from less than 2 to 68 cm.kyr-1. The highest sedimentation rate values were found in a low-energy (ría type) coastal system as well as in the upwelling zones of Santa Catarina and Cabo Frio. The lowest rates were found on the outer shelf and upper slopes. Our results confirm the strong dependency of the shelf currents, with an emphasis to the terrigenous input from the Río de La Plata outflow which is transported via the Brazilian Coastal Current, as well as of the coupled Brazil Current - Intermediate Western Boundary Current (BC-IWBC) dynamics on the sedimentary processes. At least three indicators ofthe paleo sea level were found at 12200 yr BP (conventional radiocarbon age) (103 meters below sea level - mbsl),8300-8800 cal yr BP (13 mbsl) and 7700-8100 cal yr BP (6 mbsl).

Objetivou-se com este trabalho caracterizar o efeito de diferentes temperaturas sobre a distribuição de Na+, Cl- e K+ em raízes, caules e folhas de feijão caupi pré-tratadas com NaCl. Após o período de aclimatação as plantas foram divididas em 2 grupos: 0 NaCl e 100 mM de NaCl por 2 dias. Posteriormente, as plantas foram divididas em 4 subgrupos e submetidas a temperaturas crescentes de 27, 32, 37 e 42 ºC, separadamente, por um fotoperíodo de 12 h para cada temperatura. O tratamento sem NaCl a 27 ºC foi adotado como referência. As concentrações de Na+ e Cl- nos diferentes órgãos foram aumentadas pelo pré-tratamento com NaCl e esta acumulação foi intensificada com a exposição a altas temperaturas. Nas raízes, por exemplo, observou-se que na temperatura de 42 ºC as concentrações de Na+ foram 4 vezes maiores do que nas folhas, enquanto o Cl- se acumulou principalmente nas folhas, tendo um aumento de 20 vezes na concentração deste íon em relação às plantas referência. Inversamente, as concentrações de K+ foram reduzidas em todos os órgãos analisados. Desta forma, conclui-se que temperaturas elevadas afetam a distribuição de íons nos diferentes órgãos afetando diretamente a homeostase iônica das plantas.
The purpose of this study was to characterize the effect of temperature on the distribution of Na+, Cl- and K+ in roots, stems and leaves of cowpea pre-treated with NaCl. After the acclimation period, plants were divided into two groups: 0 NaCl and 100 mM NaCl for 2 days. Subsequently, the plants were divided into 4 sub-groups and subjected to increasing temperatures of 27, 32, 37 and 42 ºC, separately, for a photoperiod of 12 hours at each temperature. The treatment without NaCl at 27 ºC was used as reference. The concentrations of Na+ and Cl- in different organs were increased by pretreatment with NaCl and this accumulation was intensified by exposure to high temperatures. In roots, for example, at temperature of 42 ºC concentrations of Na were four times higher than in leaves. While Cl- accumulated mainly in leaves, with a 20-fold increase in the concentration of this ion in relation to reference plants. Inversely, K+ concentrations were reduced in all organs analyzed. Thus, it is conclude that high temperatures affect the distribution of ions in different organs directly affecting ion homeostasis in plants.

OBJETIVO: Avaliar a concentração da elastase-1 (EL-1) fecal em pacientes pediátricos com fibrose cística, portadores da mutação ∆F508. MÉTODOS: Estudo transversal com amostras colhidas consecutivamente de 51 pacientes com idade entre 4 meses e 17 anos (média 9,11±4,74), sendo 32 (62,8%) pacientes do sexo masculino. Houve coleta de dados clínico-demográficos e do tipo de mutação. A insuficiência pancreática exócrina foi definida pela atividade da EL-1 fecal < 200 µg/g. A quantificação da EL-1 foi realizada pelo método ELISA monoclonal (ScheBo Biotech AG, Germany). A suplementação pancreática foi utilizada em 46 (90,2%) pacientes. RESULTADOS: Quarenta e um (80,4%) pacientes apresentaram insuficiência pancreática (EL-1 fecal < 100 µg/g), sendo 17 (41,5%) homozigotos, 14 heterozigotos (34,1%) e 10 sem ∆F508 (24,4%). Ao considerar a mutação, houve associação estatisticamente significativa entre os homozigotos e a concentração da EL-1 fecal < 100 µg/g (p = 0,010). Todos os pacientes considerados insuficientes pancreáticos (n = 41) pelo teste utilizavam suplemento pancreático. Dez (19,6%) apresentaram EL-1 fecal > 200 µg/g, e 5/10 (50%) utilizavam enzimas. CONCLUSÕES: A atividade de EL-1 fecal < 100 µg/g, indicativa de insuficiência pancreática, apresentou-se em 17/17 (100%) dos homozigotos, conforme o esperado, sendo menos frequente nos heterozigotos para ∆F508 e nos pacientes com ausência dessa mutação. Não houve relação entre a concentração da EL-1 fecal com idade e sexo dos pacientes. O teste foi padronizado, é de fácil execução e poderá ser utilizado para avaliação da função pancreática dos pacientes com fibrose cística.
OBJECTIVE: To assess the concentration of faecal elastase-1 (EL-1) in pediatric patients with cystic fibrosis with mutation ∆F508. METHODS: Cross-sectional study with samples collected consecutively from 51 patients aged 4 months to 17 years old (mean 9.11±4.74); 32 (62.8%) patients were male. Clinical-demographic data were collected, as well as data on the type of mutation. Exocrine pancreatic insufficiency was established by the activity of faecal EL-1 < 200 µg/g. EL-1 was quantified through the monoclonal ELISA method (ScheBo Biotech AG, Germany). Pancreatic supplements were used in 46 (90.2%) patients. RESULTS: Forty-one (80.4%) patients presented with pancreatic insufficiency (EL-1 fecal < 100 µg/g): 17 (41.5%) were homozygous, 14 were heterozygous (34.1%) and 10 were non-∆F508 (24.4%). Regarding the mutation, there was a statistically significant association of homozygosity with faecal EL-1 concentration < 100 µg/g (p = 0.010). All patients considered to be pancreatic insufficient (n = 41) by the test were using pancreatic supplements. Ten (19.6%) presented faecal EL-1 > 200 µg/g, and 5/10 (50%) used enzymes. CONCLUSIONS: The activity of faecal EL-1 < 100 µg/g, indicating pancreatic insufficiency, was observed in 17/17 (100%) of homozygous patients, as expected, and was less frequent in patients who were heterozygous for ∆F508 and in patients without the mutation. There was no association of faecal EL-1 concentration with age and sex of patients. The test was standardized, is easy to execute, and can be used to assess the pancreatic status of patients with cystic fibrosis.
