The Mediating Role of Emotion Regulation in the Relationship Between Sexual Mindfulness and Relational Quality in a Sample of Iranian Women.

Mindfulness during sex has shown many positive relational and sexual outcomes. However, little is known about the ways in which sexual mindfulness works to improve an individual's experience. This study investigated the mediating role of emotion regulation strategies in the relationship between sexual mindfulness and relational quality in a sample of Iranian women. Using a multi-stage cluster sampling method, we examined data from 265 women aged 19 to 50 years (M = 31.76, SD = 8.47). Results showed a significant positive relationship between relational quality and sexual mindfulness (p < .001, ß = .13), sexual mindfulness and reappraisal strategy (p < .001, ß = .65), and relational quality and reappraisal strategy (p < .001, ß = .78). The reduction of the path coefficient in the full mediation model compared to the direct model indicating a partial mediation role of the reappraisal strategy was confirmed in relation to sexual mindfulness and relational quality. These findings may help identify one path, emotion regulation, through which sexual mindfulness works. This study provides psychologists and counselors evidence that both sexual mindfulness and emotion regulation are positive skills that likely improve the quality of their clients' relationships.

ICP-OES assessment of trace and toxic elements in Ziziphora clinopodioides Lam. from Iran by chemometric approaches.

The aim of the study was to evaluate the concentrations of some essential and toxic elements (including Ca, K, Mg, Na, Fe, Cu, Mn, Zn, Co, Mo, Pb, Ni, Cr, and Cd) in Ziziphora clinopodioides Lam. (endemic Iranian herb) from 14 different regions by ICP-OES (inductively coupled plasma-optical emission spectrometry) method followed by multivariate statistical analyses. The analytical performances were assessed as the limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy. Multivariate analysis (CA, PCA and HCA) showed the elemental distribution in the roots were higher than the shoots and significant element was Ca between regions. Three principal components (PCs) explained 77.94% of the total variance. They were as follows: PC1 with Cu, Zn, K, Cr, Ni, and Mn; PC2 with Na, Ca, Pb, and Fe; and PC3 with Mg. Hierarchical cluster analysis indicated four groups of Z. clinopodioides samples from the 14 regions based on their trace and toxic element levels. These chemometric approaches with multivariate analysis enable researchers to understand and quantify the relationship between the variables in a data set, and the analysis considers more than one factor. The concentrations of Cu, Na, Mn, Zn, and Pb in most Z. clinopodioides samples were below the WHO (world health organization) limit for herbal medicines (10, 51,340, 200, 50, and 10 µg g-1 respectively), while Fe and Ca levels were higher than allowed (15 and 614 µg g-1 respectively). However, the WHO limit for Mg, K, Co, and Mo in medicinal plants has not yet been determined. The results of this study confirmed that different parts of Z. clinopodioides can be used as an important source for human nutrition due to its essential mineral elements.
