“…Work over the last decade has identified an ever-growing list of potential thioredoxin targets (370). Thioredoxin regulation is now known also to occur in other plant cell compartments such as the cytosol and mitochondria (26,233,269,346), and is mediated by a family of proteins that can be classed into different groups (239,269). Certain plastidial types of thioredoxins play a role in peroxiredoxin-linked peroxide metabolism (48,66,424).…”

Reactive oxygen species (ROS) have multifaceted roles in the orchestration of plant gene expression and gene-product regulation. Cellular redox homeostasis is considered to be an "integrator" of information from metabolism and the environment controlling plant growth and acclimation responses, as well as cell suicide events. The different ROS forms influence gene expression in specific and sometimes antagonistic ways. Low molecular antioxidants (e.g., ascorbate, glutathione) serve not only to limit the lifetime of the ROS signals but also to participate in an extensive range of other redox signaling and regulatory functions. In contrast to the low molecular weight antioxidants, the "redox" states of components involved in photosynthesis such as plastoquinone show rapid and often transient shifts in response to changes in light and other environmental signals. Whereas both types of "redox regulation" are intimately linked through the thioredoxin, peroxiredoxin, and pyridine nucleotide pools, they also act independently of each other to achieve overall energy balance between energy-producing and energy-utilizing pathways. This review focuses on current knowledge of the pathways of redox regulation, with discussion of the somewhat juxtaposed hypotheses of "oxidative damage" versus "oxidative signaling," within the wider context of physiological function, from plant cell biology to potential applications.

“…FOS fermentation in the colon results in increased levels of short chain fatty acids (SCFA) which lower the pH in the intestinal lumen. This can provide an explanation to the reports that these fructans lead to a decrease in the number of harmful bacteria in the colon (such as Clostridium, Streptococcus faecallis and Escherichia coli) [21,25].…”

“…As a consequence, when these carbohydrates reach the colon they selectively stimulate the growth of beneficial bacteria such as bifidobacteria, which do contain specific enzymes for their degradation, i.e. β-fructosidases [16,21,25]. Therefore, inulin, FOS and scFOS are classified as 'nondigestible' carbohydrates, with a calorie value of 1.5-2.0 kcal/g [24].…”

“…It was reported that soy isofl avones reduce the markers of oxidative damage and improve the total antioxidant status [Bazzoli et al, 2002;Chen et al, 2005]. The scientifi c research has also suggested the antioxidant effect of inulin and indicated that inulin protects the human colon mucosa from lipopolysaccharide (LPS)-induced damage related to the protective effect of inulin against LPS-induced oxidative stress [Stoyanova et al, 2011;Van den Ende et al, 2011].…”

Key words: drink, soy protein isolate, prebiotic dietary fi ber inulin, oxidized low density lipoproteins Due to selection of appropriate ingredients and parameters, a microbiologically-safe drink enriched with soy protein isolate (SPI) and prebiotic dietary fi ber inulin with high scores of acceptability was produced. The results of medical nutrition survey showed that on the 21 day of using drink the level of oxidized low density lipoproteins (LDL) signifi cantly decreased while the other biochemical parameters of blood of healthy patients as compared to the control tests remained unchanged. As well there was no apparent impact on the intestinal microfl ora balance of recipients established.
