“…Regarding the effect of PQ Naspolini et al 30 showed that PQ exposure and the oxidative stress response resulted in decreased glucose transport into neural cells associated with a compensatory increase in lactate dehydrogenase (LDH) activity suggesting the importance of lactate as energy fuel. To address the question if EHMT1 haploinsu ciency impacts LDH expression we measured the transcript levels of the two subunits of LDH, LDHA which has higher a nity for pyruvate and, LDHB with higher a nity for lactate.…”

“…This suggests that VPA alleviated lipid peroxidation, which is supported by other studies (Chaudhary & Parvez, 2018; Ourique et al, 2016). The level of TBARS can be used to measure the level of lipid peroxidation as previously described (Liu et al, 2021; Naspolini et al, 2021). In this study, the plasma concentration of TBARS decreased significantly after BS in the LR and VR groups but increased in the NR group.…”

“…Efeitos deletérios da exposição de trabalhadores à herbicidas são bem reportados na literatura para diferentes princípios ativos, como Paraquat (Tsai, 2013), Glifosato (Myers et al, 2016) A toxidade do Paraquat em humanos e mamíferos está associada ao seu potencial redox, mesmo mecanismo que confere a ele atividade herbicida. O mecanismo de ação tóxica do Paraquat envolve reações de redução-oxidação cíclicas, no qual são produzidas espécies reativas de oxigênio e a depleção de NADPH reduzido (Tsai, 2013), o que confere alta toxidade a humanos (Naspolini et al, 2021). Se ingerido, o Paraquat produz uma sensação de queimação na boca e garganta, levando a náuseas, vômitos, diarreia etc.…”

“…Estudos experimentais em animais e evidências epidemiológicas também indicam que a exposição crônica a esse herbicida pode estar associada ao desenvolvimento da doença de Parkinson (Tsai, 2013). Esse histórico de danos à saúde humana levaram o Paraquat a ser banido ou severamente restringido em mais de 20 países ao redor do mundo; porém somente em setembro de 2020 o Brasil entrou na lista de países que o baniram, muito embora seu uso em algumas lavouras brasileiras ainda era permitido até julho de 2021 (Naspolini et al, 2021).…”
