In this paper, a study on the influence of extraction solvent on the active principles content of purslane - Portulaca oleracea extracts was performed. For the study were used both fresh and dried plants, chopped by plant chopping machine. The following extracts were obtained and analysed in the solvent systems mentioned below: (fresh) purslane extract in Ethanol 30%, (dry) purslane extract in Ethanol 30%; (fresh) purslane extract in EtOH 70%, (dry) purslane extract in EtOH 70%; (fresh) purslane extract in propylene glycol 20%, (dry) purslane extract in propylene glycol 20%; (fresh) purslane extract in PG 100%, (dry) purslane extract in PG 100%; (fresh) purslane extract in glycerine 20%, (dry) purslane extract in glycerine 20%; (fresh) purslane extract in R glycerine, (dry) purslane extract in R glycerine; purslane hydro-alcoholic glycerine extract. The results obtained in the study performed on purslane extracts in different solvents show that the capitalization of purslane can become very profitable and with beneficial effects on economy in our country, both in terms of food and as medicinal plant.

This research was carried out to assess the mineral components of the selected vegetable Portulaca Oleracea which is commonly used as food; Ca, Mg, and Fe analyzed by Atomic Absorption Spectrophotometric (AAS) and Na, and K Flame photometric spectrophotometer. The results of macro-elements obtained having values of Ca (138.75, 140.4 ppm) for Iraqi and Lebanon origin respectively, Mg (214.53, 211.71 ppm) for Iraqi and Lebanon origin respectively, Fe is found to be (8.9, 7.03 ppm) for Iraqi and Lebanon origin respectively, Na (4, 38ppm) for Iraqi and Lebanon origin respectively, and K (18, 16 ppm) for Iraqi and Lebanon origin respectively; The indication results of this vegetable has the potential to provide essential nutrients to the human beings and it is found to be a good source of minerals particularly Ca, Mg, Fe, Na and K.

The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo modulates the arousal value of emotion with faster tempi associated with stronger feeling of happiness and anger and this effect is associated in EEG with an increase of frontal activation in the left hemisphere. By contrast, slow tempo induced decreased frontal activation in the left hemisphere. Some interactive effects were found between mode and tempo: An increase of tempo modulated the emotion differently depending on the mode of the piece.

The Relationship

Abstract. Background: Acute suicidal affective disturbance (ASAD) has been proposed as a suicide-specific entity that confers risk for imminent suicidal behavior. Preliminary evidence suggests that ASAD is associated with suicidal behavior beyond a number of factors; however, no study to date has examined potential moderating variables.  Aims: The present study tested the hypotheses that physical pain persistence would moderate the relationship between ASAD and (1) lifetime suicide attempts and (2) attempt lethality. Method: Students ( N = 167) with a history of suicidality completed self-report measures assessing the lifetime worst-point ASAD episode and the presence of a lifetime suicide attempt, a clinical interview about attempt lethality, and a physical pain tolerance task. Results: Physical pain persistence was a significant moderator of the association between ASAD and lifetime suicide attempts ( B = 0.00001, SE = 0.000004, p = .032), such that the relationship between ASAD and suicide attempts strengthened at increasing levels of pain persistence. The interaction between ASAD and pain persistence in relation to attempt lethality was nonsignificant ( B = 0.000004, SE = 0.00001, p = .765). Limitations: This study included a cross-sectional/retrospective analysis of worst-point ASAD symptoms, current physical pain perception, and lifetime suicide attempts. Conclusion: ASAD may confer risk for suicidal behavior most strongly at higher levels of pain persistence, whereas ASAD and pain perception do not influence attempt lethality.
