Kinetics of lipid oxidation in foods

Abstract: This review shows how the basic kinetics of lipid oxidation can be simplified for application to the study of food deterioration. The physical and chemical factors that control oxidation are examined and analyzed in terms of food structure and composition. Studies of oxidation of several food items are examined in light of these kinetics and mechanisms.

Towards environmental systems biology of Shewanella

Abstract: Bacteria of the genus Shewanella are known for their versatile electron-accepting capacities, which allow them to couple the decomposition of organic matter to the reduction of the various terminal electron acceptors that they encounter in their stratified environments. Owing to their diverse metabolic capabilities, shewanellae are important for carbon cycling and have considerable potential for the remediation of contaminated environments and use in microbial fuel cells. Systems-level analysis of the model species Shewanella oneidensis MR-1 and other members of this genus has provided new insights into the signal-transduction proteins, regulators, and metabolic and respiratory subsystems that govern the remarkable versatility of the shewanellae.

Anthocyanins in vegetative tissues: a proposed unified function in photoprotection

Abstract: The function of anthocyanins in green, vegetative tissues has always been a contentious issue. Here we evaluate their proposed photoprotective function since recent findings have shown that anthocyanins reduce photoinhibition and photobleaching of chlorophyll under light stress conditions. Anthocyanins generally accumulate in peripheral tissues exposed to high irradiance, although there are some exceptions (e.g. accumulation in abaxial leaf tissues and in obligatory shade plants) and accumulation is usually transient. Anthocyanin accumulation requires light and generally coincides with periods of high excitation pressure and increased potential for photo-oxidative damage due to an imbalance between light capture, CO2 assimilation and carbohydrate utilization (e.g. greening of developing tissues, senescence and adverse environmental conditions). Light attenuation by anthocyanin may help to re-establish this balance and so reduce the risk of photo-oxidative damage. Although it has been suggested that anthocyanins may act as antioxidants, the association between anthocyanins and oxidative stress appears to relate to the ability of anthocyanins to reduce excitation pressure and, hence, the potential for oxidative damage. The various aspects of anthocyanin induction and pigmentation presented here are compatible with, and support, the proposed general role of anthocyanins as photoprotective light screens in vegetative tissues.

Negative affect and social judgment: The differential impact of anger and sadness

Abstract: The overwhelming majority of research on affect and social information processing has focused on the judgments and memories of people in good or bad moods rather than examining more specific kinds of emotional experience within the broad categories of positive and negative affect. Are all varieties of negative affect alike in their impact on social perception? Three experiments were conducted to examine the possibility that different kinds of negative affect (in this case, anger and sadness) can have very different kinds of effects on social information processing. Experiment I showed that angry subjects rendered more stereotypic judgments in a social perception task than did sad subjects, who did not differ from neutral mood subjects. Experiments 2 and 3 similarly revealed a greater reliance upon heuristic cues in a persuasion situation among angry subjects. Specifically, their level of agreement with unpopular positions was guided more by the credibility of the person advocating the position. These findings are discussed in terms of the impact of emotional experience on social information-processing strategies.
