SummaryRoot-knot nematodes, Meloidogyne spp., cause great losses to coffee crops in Brazil and worldwide. However, little is known about the physiological changes that these pathogens induce in coffee plants. The present work aimed to compare the physiological variables of coffee seedlings (Coffea arabica ‘Catuaí Vermelho IAC 144’) infected with Meloidogyne paranaensis or M. exigua with healthy coffee plants. Nematode-infected plants showed reductions in height and starch content in roots compared to healthy plants. In addition, the infected plants had a reduction in transpiration, stomatal conductance and CO2 concentration. However, only the coffee seedlings infected with M. paranaensis showed reduction in the rate of photosynthesis. Nematode-infected plants had lower leaf contents of P, K, Mn and Fe when compared to healthy plants. However, only coffee seedlings parasitised by M. paranaensis exhibited lower levels of Ca in the leaves. Therefore, M. paranaensis and M. exigua, with emphasis on M. paranaensis, alter the normal coffee seedling physiology.

A gestação tem sido, geralmente, um acontecimento que proporciona grande felicidade para a grávida e para a família. O parto é um evento rodeado de emoções e sensações, em especial para a mulher e para o bebê, que são as figuras principais. Este artigo busca proporcionar conhecimento quanto à atuação do fisioterapeuta durante o período do pré-parto, apontando os principais benefícios dessa presença nesse período que é extremamente importante para mãe, filho e família. No âmbito do atendimento hospitalar a fisioterapia atua utilizando, principalmente, cinesioterapia, banhos quentes, massagens terapêuticas, técnicas respiratórias, caminhada, posturas verticais, exercícios com a bola suíça e neuroeletroestimulação transcutânea (TENS). Esses recursos buscam proporcionar ao paciente alívio da dor e conforto durante o trabalho de parto. Foi realizada uma pesquisa documental através de busca online em bases SCIELO, Portal de Periódicos da CAPS, LILACS, BIREME e livros do acervo da biblioteca da Faculdade Guaraí, totalizando uma análise de 21 documentos. Ao finalizar a pesquisa, verificou-se que o fisioterapeuta é um profissional extremamente importante no atendimento à gestante no pré-parto, trabalho de parto e pós-parto. Através de um acompanhamento especializado à gestante conquista-se uma assistência de qualidade aumentando o bem-estar para mãe e bebê no período gestacional e em todo o processo de parto.

As a result of more restrictive legislation regarding the use of pesticides, over the last two decades, the demand for new soil fumigants has increased. These compounds can come from a variety of sources, including organic residues. In this study, we identified in the cassava wastewater volatiloma a molecule with potential to be developed as a new fumigant nematicide. Cassava wastewater (20 mL) releases volatile compounds toxic to Meloidogyne javanica second-stage juveniles (J2), causing J2 mortality up to 89%. Through gas chromatography–mass spectrometry, eight compounds were identified in the cassava wastewater volatiloma, with alcohols being the major class. The compounds ethyl butanoate and butyric acid identified in cassava wastewater volatiloma were selected for in vitro nematicidal activities and substrate fumigation tests. The lethal concentration predicted LC50–48 hr values (effective doses to kill 50% of M. javanica J2 population after 48 h of exposure) were 172.6 μg ∙ mL - 1 and 301.2 μg ∙ mL - 1 for butyric acid and ethyl butanoate, respectively. In a pot assay, the application of butyric acid and ethyl butanoate as a soil fumigant, at a dose of 0.5 mL ∙ kg - 1 substrate, significantly (P < 0.05) decreased M. javanica infectivity and reproduction compared to the negative control (water). However, ethyl butanoate proved to be a more efficient soil fumigant (P < 0.05) than butyric acid, as its application reduced the number of galls and eggs to the level of the commercial fumigant Dazomet. This study is the first to demonstrate the potential of ethyl butanoate as a soil fumigant against M. javanica.
