Background: Postpartum is a significant transition period for women and could be markedly stressful. Objectives: Postpartum stress is a well-established risk factor for poor parenting practices and inadequate mother-infant interaction. The present study aimed to assess adaptation to motherhood and its influential factors in the first year postpartum in Iranian women. Methods: This cross-secti...

Background: Mothers with preterm infants experience numerous stressful problems which can be associated with negative effects on maternal role adaptation. Objectives: The present study aimed to evaluate maternal role adaptation in mothers with late-preterm infants and its related factors. Methods: This descriptive-analytical study was conducted in Ayatollah Mousavi Hospital in Zanjan, Iran du...

Escalating climate risks to critical infrastructures in Europe Climate hazard damages to critical infrastructures in Europe will escalate as a result of global warming, with an uneven territorial distribution of future impacts and adaptation needs. This calls for (i) an EU commitment to continue supporting adaptation action in Member States (e.g. through Cohesion Policy investments) and to coor...

When stimulated with a constant stimulus, many neurons initially respond with a high spike frequency that then decays down to a lower steady-state frequency (Fig. 1 A). This dynamics of the spike frequency response is referred to as “spike-frequency adaptation”. Spike-frequency adaptation is a process that is slower than the dynamics of action potential generation. Spikefrequency adaptation by ...

Animals adapt action-selection policies when the relationship between possible actions and associated outcomes changes. Prefrontal cortical neurons vary their discharge patterns depending on action choice and rewards received and undoubtedly play a pivotal role in maintaining and adapting action policies. Here, we recorded neurons from the medial precentral subregion of mouse prefrontal cortex ...

1. The phenomenon of dark adaptation of the eye of Limulus is reflected in the behavior of the action potentials obtained upon stimulation by light. The method of obtaining and recording these action potentials has been described in an earlier paper. 2. By determining the intensity of stimulus necessary to produce an electric response of a given magnitude (as to maximum action potential), at va...

Researchers have begun to delineate the precise nature and neural correlates of the cognitive processes that contribute to motor skill learning. The authors review recent work from their laboratory designed to further understand the neurocognitive mechanisms of skill acquisition. The authors have demonstrated an important role for spatial working memory in 2 different types of motor skill learn...

eighteen wheat breeding lines were evaluated along with two check cultivars across nine locations of temperate zone of iran during two crop seasons (2003-2004 and 2004-2005). field records were taken for some important traits especially grain yield. combined anova for nine locations in the first season and for seven locations in both seasons was undertaken. in each case, additive main effects a...

1. A single-celled, elongating sporangiophore of Phycomyces responds to a sufficient increase in intensity of illumination by a brief increase in growth rate. This is the "light-growth response" of Blaauw. 2. The reaction time is compound, consisting of an exposure period and a latent period (this comprising both the true latent period resulting from photochemical action and any "action time" n...

Human mirror mechanisms (MMs) respond during both performed and observed action and appear to underlie action goal recognition. We introduce a behavioral procedure for discovering and clarifying functional MM properties: blindfolded participants repeatedly move beans either toward or away from themselves to induce motor adaptation. Then, the bias for perceiving direction of ambiguous visual mov...
