Quantifying salt sensitivity

Inner surfaces of blood vessels and outer surfaces of erythrocytes are coated with a negatively charged protective film of proteoglycans, which serves as an effective buffer system for the positively charged sodium ions. If this protective coating is poorly developed or impaired, it loses its buffering capacity. As a consequence, the organism becomes increasingly sensitive to sodium, which in the long run leads to organ damage, especially if daily salt consumption is high. Recently, it has become possible to quantify salt sensitivity using a technically simple method – the salt blood test (SBT). Aim of this mini-review is to explain the physiological concept underlying the SBT and its potential practical relevance in the prevention of cardiovascular disease.

Peer Victimization and Depressive Symptoms During Adolescence: Examining the Roles of Social Support and Internalizing Coping

The purpose of this study was to examine how two coping strategies together moderate the relationship between peer victimization and adjustment among young adolescents. Sixth-grade adolescents from California, Oregon, and Wisconsin ( N = 1,058) self-reported peer victimization, depressive symptoms, and their utilization of social support seeking and internalizing coping. A regression analysis showed a significant three-way interaction between peer victimization, internalizing coping, and social support seeking in predicting depressive symptoms. Further analyses revealed that social support seeking only buffered the negative effects of peer victimization for participants who scored high on internalizing coping. Despite mean-level gender differences in these variables, gender did not moderate this association, suggesting that social support is an effective buffer against depressive symptoms following peer victimization for both boys and girls. These results suggest that attending to the variety of coping strategies adolescents employ simultaneously will help further our understanding of peer victimization outcomes.

Touch reduces romantic jealousy in the anxiously attached

Feelings of jealousy are usually detrimental to relationships, often resulting in negative outcomes ranging from conflict to violence and relationship dissolution. Anxiously attached individuals are especially prone to jealousy in their relationships and are therefore especially likely to experience negative outcomes of jealousy. In this research, we examined the effectiveness of both touch and a traditional security prime as a potential means of reducing feelings of jealousy for individuals who are high in anxious attachment. Individuals in romantic relationships were induced to feel jealous, during which time they were randomly assigned to receive affectionate touch from their partners, a traditional nontouch security prime, or no intervention (control). Results revealed that anxious attachment was associated with high levels of jealousy, and touch was an effective buffer against jealous feelings for individuals high in anxious attachment. The traditional security prime did not buffer jealous feelings. Implications of results for potential relationship interventions are discussed.
