1. Efeito do trans-2-nonenal na qualidade sensorial da cerveja
A mudança do perfil sensorial da cerveja ao longo do envelhecimento tem sido apontada como um dos maiores problemas de qualidade nessa bebida. Um dos off-flavours bastante conhecido é o associado ao “papelão” ou “cerveja oxidada”. Esse off-flavour tem sido associado ao composto trans-2-nonenal, um acetaldeído. O objetivo dessa pesquisa foi avalia

2. Folatos, capacidade antioxidante e trans-2-nonenal em cerveja brasileira / Folate, antioxidant capacity and E-2-nonenal in Brazilian beer
In the present study methods were adapted and applied to quantify levels of folate, antioxidant capacity assessment and E-2-nonenal quantification in Brazilian beers. 5 brands of Pilsen, non-alcoholic and Malzbier beers were used, in can and amber bottle. For determination of folates (folic acid - FA, 10-methyl-folic acid - 10Methyl, 5-methyltetrahydrofolate

3. Efeito das variaveis de transporte e estocagem sobre a estabilidade sensorial de cervejas tipo Pilsen. / Influence of transport and storage variables on the flavor stability of Pilsen beer.
A cerveja tipo Pilsen é líder de vendas no mercado mundial. Ocorre mundialmente a tendência de se produzir cervejas Pilsen com menos amargor, menos corpo e mais claras. O grande desafio atual da indústria cervejeira é a garantia do frescor e leveza desse produto durante todo o seu tempo de vida de prateleira. Com a globalização, as cervejas são trans

4. A signalling role for 4-hydroxy-2-nonenal in regulation of mitochondrial uncoupling
Oxidative stress and mitochondrial dysfunction are associated with disease and aging. Oxidative stress results from overproduction of reactive oxygen species (ROS), often leading to peroxidation of membrane phospholipids and production of reactive aldehydes, particularly 4-hydroxy-2-nonenal. Mild uncoupling of oxidative phosphorylation protects by decreasing

5. Trans-4-hydroxy-2-nonenal inhibits nucleotide excision repair in human cells: A possible mechanism for lipid peroxidation-induced carcinogenesis
Lipid peroxidation (LPO) is a cellular process that commonly takes place under normal physiological conditions. Under excessive oxidative stress, the level of LPO becomes very significant, and a growing body of evidence has shown that excessive LPO may be involved in carcinogenesis. Trans-4-hydroxy-2-nonenal (4-HNE) is a major product of LPO, and its level b

6. Inactivation of ethanol-inducible cytochrome P450 and other microsomal P450 isozymes by trans-4-hydroxy-2-nonenal, a major product of membrane lipid peroxidation.
Of the microsomal P450 cytochromes, the ethanol-inducible isoform, P450 2E1, is believed to be predominant in leading to oxidative damage, including the generation of radical species that contribute to lipid peroxidation, and in the reductive beta-scission of lipid hydroperoxides to give hydrocarbons and aldehydes. In the present study, the sensitivity of a

7. Lipid mediator interplay: resolvin D1 attenuates inflammation evoked by glutathione-conjugated lipid peroxidation products
Non-enzymatic oxidation of cellular lipids, one of the characteristic features of inflammation, leads to formation of highly reactive and toxic α,β-unsaturated aldehydes, such as 4-hydroxy-trans-2-nonenal (HNE). Conjugation of HNE with reduced glutathione (GS-HNE) is widely believed to represent a form of detoxification. The study by Spite et al. in the cu
