An experiment assessed the joint effect of dispositional need for closure (NFC) and task difficulty on engagement-related myocardial beta-adrenergic activity. Participants who scored either low or high on the NFC scale performed an ambiguous categorization task with either low or high difficulty. Confirming the theory-derived predictions, task difficulty effects on pre-ejection period (PEP) rea...

The present study examined cognitive vulnerability to relapses of depression by clarifying the characteristics of "cognitive reactivity" in people with recurrent major depressive episodes. Study 1-1 and 1-2 developed a Japanese version of the Leiden Index of Depression Sensitivity-Revised (LEIDS-R), which assessed cognitive reactivity, and evaluated the reliability and validity of the scale. St...

Emotional reactivity following lesions in structures corresponding to the main components of dorsal prefrontal system of the monkey was evaluated in a total of 165 rats by a six-categorial rating scale. Frontomedial cortical damage (FM) and lesions in anterodorsal (DH) or posteroventral (VH) hippocampal regions elicited marked increases in emotional reactivity, relative to sham operated control...

In the conversion of fuel in the Tehran Research Reactor core from Highly- Enriched Uraniutn to Low-Enriched Uranium fuel neutronics analysis, thermal hydraulic calculations and kinetic performance of the core have to be studied. In this study, static and dynamic core performance for HEU and LEU fuels were investigated. In static conditions, two groups of neutron flux distributions in axia...

Many chemical concepts can be well defined in the context of quantum theories. Examples are electronegativity scale Mulliken and Jaffé hard soft acids bases concept Pearson. The sound theoretical basis allows for a systematic definition such concepts. However, while they often used to describe compare processes terms reactivity, their predictive power remains unclear. In this work, we elaborate...

Background: The boundaries between mood states in bipolar disorders are not clear when they are associated with mixed characteristics. This leads to some confusion to define appropriate therapeutic strategies. A dimensional approach might help to better define bipolar moods states and more specifically those with mixed features. Therefore, we proposed a new tool based on a dimensional approach,...

AIM To evaluate the effects of almost continuous skin-to-skin contact (SSC) on salivary cortisol, parental stress, parental depression, and breastfeeding. STUDY DESIGN This is a randomised study engaging families of late preterm infants (32-35 weeks gestation). Salivary cortisol reactivity was measured in infants during a nappy change at one month corrected age, and in infants and mothers dur...

A new aromaticity definition is advanced as the compactness formulation through the ratio between atoms-in-molecule and orbital molecular facets of the same chemical reactivity property around the pre- and post-bonding stabilization limit, respectively. Geometrical reactivity index of polarizability was assumed as providing the benchmark aromaticity scale, since due to its observable character;...
