A reatividade negativa oriunda da poliquimioterapia imposta na Hanseníase

Introdução: A hanseníase é uma doença infectocontagiosa, que devido às repercussões clínicas e aos dados epidemiológicos é considerada de notificação compulsória. Contudo, esse transtorno quando é precocemente identificado e adequadamente manejado, evita consideravelmente o círculo vicioso de contágio e as manifestações clínicas que tornam a doença tão alvo de estigma. Objetivo: Descrever a reação negativa oriunda da poliquimioterapia imposta na hanseníase. Metodologia: Trata-se de uma revisão narrativa de literatura, fundamentada nas plataformas do Scielo, Pubmed, Lilacs e demais literaturas pertinentes ao tema, utilizando-se os seguintes descritores: Reação Hansênica, Efeitos Adversos e Poliquimioterapia, no período de janeiro de 2023. Resultados e Discussão:  Atualmente, o protocolo terapêutico voltado para a Hanseníase é a poliquimioterapia e possui boa eficácia e tolerância pela maioria dos pacientes.  No advém, a minoria destes apresenta reações adversas que variam de leve a exacerbadas e que devem ser devidamente classificados e orientados para outras opções farmacológica, objetivando impedir que o paciente abandone o tratamento, junto às enormes repercussões oriundas deste, e propiciar melhor qualidade de vida. Conclusão: Estima-se que o tratamento da Hanseníase é algo importante e indispensável para evitar problemas de saúde pública, mas este se baseia em uma alta carga associada de remédios potentes, a qual alguns portadores possuem sensibilidade e se orientados, podem continuar o tratamento até o alcance da cura.&nbsp

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Frequency of anareobic power among brasilians based on dermatoglyphics and R577X polymorphism of the ACTN3 protein

Dermatoglyphics and analysis of the Alpha-Actinin-3 gene are evaluative instruments frequently used to identify the sportive and general population profile associated with physical performance. This research aimed to determine, based on dermatoglyphic characteristics and the R577X polymorphism of Alpha-Actinin-3, the percentage of people in the State of Paraíba/Brazil, with unfavorable characteristics to excelling in sports that require anaerobic power. A descriptive study of profiles, with ex post facto typology, was performed. The dermatoglyphic fingerprint characteristics of 309 people (149 males and 160 females) were identified, and ACTN3 genotype was analyzed in 96 people (40 males and 56 females). The dermatoglyphic data indicated that 5.8% of the study population fit the classification of anaerobic muscle power predisposition, while 94.2% did not fit on it. The genetic frequency analysis indicated that 19.8% of subjects in the sample had the XX mutant genotype. These results represent a substantial error reduction in the search for and selection of athletes with the potential for high performance, especially in those sports that require AMP

Utilização das folhas de comigo-ninguém-pode (Dieffenbachia seguine) como bioadsorvente para a remoção de íons metálicos

The heavy metals can become a concern due to the possibility of movement and consequent contamination of superficial layers of soil and groundwater, compromising the health of plants and animals. Among the decontamination methods, bioadsorption has shown good economic and ecological results. In this work, leaves of the comigo-ninguém-pode plant have been used in the removal of Cu2+ ions from aqueous solutions. The leaves of the plants were dehydrated to a constant mass, followed by the spraying and sieving stages. Adsorptions tests were carried out in batch, consisting of 0.5 g of dehydrated leaves with 100 mL of aqueous solutions of CuSO4 in different concentrations. An evaluation of the content of oxalate ions present in the leaves was performed by the permanganimetry technique. Characterization and quantification was performed by X-ray diffraction and atomic absorption spectroscopy. Results of the adsorption tests showed that CNP leaves exhibited 93% of Cu2+ ions removal when tested in a solution whose metal concentration was 600 mg L-1. XRD patterns confirmed that the adsorbed metal incorporated into the structure of the leaves. Kinetic study showed that the adsorption of Cu2+ by the CNP leaves obeys the mathematical model of pseudo-second order. The bioadsorbent tested in this work showed high efficiency in the decontamination of effluents containing Cu2+ ions. The use of the process proposes an efficient decontamination mechanism, of low cost and high ecological value, in addition to promoting functionality to a toxic plant.A presença de metais pesados pode tornar-se motivo de preocupação em função da possibilidade de movimentação e consequente contaminação de camadas superficiais do solo e águas subterrâneas, comprometendo a saúde de plantas e animais. Dentre os métodos de descontaminação, a bioadsorção tem apresentando bons resultados econômicos e ecológicos. Neste trabalho, folhas da planta comigo-ninguém-pode (CNP) foram utilizadas na remoção de íons Cu2+ de soluções aquosas. Realizou-se a desidratação das folhas da planta em estufa, até massa constante, em seguida procedeu as etapas de pulverização e peneiramento. Os ensaios de adsorção foram realizados em batelada, sendo composto por 0.5 g das folhas desidratas com 100 mL de soluções aquosas de CuSO4 com diferentes concentrações. Uma avaliação do teor de íons oxalatos presentes nas folhas foi realizada pela técnica de permanganimetria. A caracterização e quantificação foi realizada pelas técnicas de difração de raios-X e espectroscopia de absorção atômica. Os resultados dos ensaios de adsorção mostraram que as folhas de CNP apresentaram 93% de remoção de Cu2+ quando testados em uma solução cuja concentração do metal foi de 600 mg L-1. Os difratogramas de raios-X confirmaram que o metal adsorvido incorporou na estrutura das folhas. O estudo cinético mostrou que a adsorção de Cu2+ pelas folhas de CNP obedecem ao modelo matemático de pseudossegunda ordem. O bioadsorvente testado neste trabalho apresentou elevada eficiência na descontaminação de efluentes contendo íons Cu2+. A utilização do processo utilizado propõe um mecanismo de descontaminação eficiente, de baixo custo e elevado valor ecológico, além de promover uma funcionalidade a uma espécie de planta tóxica.Palavras chave: Bioadsorção, oxalatos, cinética

Sementes de moringa como coagulante natural no tratamento de água residuária proveniente do abate de rã-touro (Lithobates catesbeianus)

The increasing consumption of clean water has resulted in a large amount of generated effluents and inadequately released to the environment. The aim of this work was to investigate seeds moringa on coagulation, flocculation and sedimentation treatments of liquid effluent from frogs slaughter system. It was evaluated a potential coagulation (mass form and as an extract) by means of jar tests varying the concentration of the coagulant. The parameters had been evaluated: apparent color, turbidity, pH, electrical conductivity, total solids dissolved, oxygen consumed and microbiological analysis. Tests results showed that the use of the moringa was favorable in the treatment of wastewater from frogs, providing removal of 96% for apparent color and 91% of turbidity. It had verified that the extract of moringa reduced in 47.5% the consumed oxygen content and 89% of thermotolerant coliforms (Escherichia coli). These results indicate that the use of moringa has a high potential as a coagulant in the treatment of wastewater, and can serve as a substitute for synthetic chemical coagulants.O crescente consumo de água potável tem resultado em uma grande quantidade de efluentes gerados e lançados de forma inadequada ao meio ambiente. Diante disto, este trabalho teve como objetivo investigar a eficiência do coagulante natural Moringa no tratamento de coagulação, floculação e sedimentação do efluente líquido proveniente do abate de rã-touro. Avaliou-se a potencialidade do coagulante (na forma mássica e como extrato) por meio de testes de jarros variando a concentração do coagulante. Foram avaliados os parâmetros: cor aparente, turbidez, pH, condutividade elétrica, sólidos totais dissolvidos, oxigênio consumido e avaliação microbiológica. Os resultados dos ensaios mostraram que a utilização do extrato de moringa na concentração de 0.125 g L-1 foi favorável no tratamento da água residuária proveniente do abate de rãs, proporcionando uma remoção de 96% da cor aparente e 91% da turbidez. Verificou-se que o extrato de Moringa reduziu em 47.5% o teor de oxigênio consumido e em 89% os coliformes termotolerantes (Escherichia coli). Estes resultados apontam que a utilização das sementes de Moringa possui elevado potencial como coagulante no tratamento de águas residuárias, podendo servir como um substituinte de coagulantes químicos sintéticos.Palavras chave: Efluente, extrato, coliformes

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
