BACKGROUND AND PURPOSE Impairment of cerebrovascular autoregulation may promote secondary brain injury in acute brain insults. Until now, only limited data are available on autoregulation in patients with spontaneous intracerebral hemorrhage. In the current study, we aimed to investigate cerebrovascular reactivity and its significance for outcome in spontaneous intracerebral hemorrhage. METHO...

Instigated by evidence for reduced responsiveness to reward in depression, the present two studies addressed the question if such anhedonic behavior would also become evident in reduced mobilization of mental effort in terms of cardiovascular reactivity. Undergraduates completed the Center for Epidemiologic Studies-Depression Scale (CES-D) and worked on mental tasks, expecting either no consequ...

Prior research has examined the relations between various facets of emotion and psychopathology, with a great deal of recent work highlighting the importance of emotion regulation strategies. Much less attention has been given to the examination of emotion reactivity. This study reports on the development and evaluation of the Emotion Reactivity Scale (ERS), a 21-item self-report measure of emo...

BACKGROUND Autonomic dysregulation has been recently reported as a feature of autism spectrum disorder (ASD). However, the nature of autonomic atypicalities in ASD remain largely unknown. The goal of this study was to characterize the cardiac autonomic profile of children with ASD across four domains affected in ASD (anxiety, attention, response inhibition, and social cognition), and suggested ...

Drugs-of-abuse may increase the salience of drug cues by sensitizing the dopaminergic (DA) system (Robinson and Berridge, 1993), leading to differential attention to smoking stimuli. Event-related potentials (ERPs) have been used to assess attention to smoking cues but not using an ERP component associated with DA-mediated salience evaluation. In this study the DA-related P2a and the P3, were c...

This review article discusses the effects of inorganic content and mechanisms on raw biomass char during gasification. The impacts inherent inorganics externally added compounds are summarized based a literature search from most recent 40 years. TGA larger-scale studies involving K-, Ca-, Si-related critically reviewed with aim understanding reaction kinetics. Differences between pathways matte...

Hyporheic zone reaction rates are highest just below the sediment-water interface, in a shallow region called benthic biolayer. Vertical variability of hyporheic leads to unexpected kinetics for stream-borne solutes, compared classical model predictions. We show that deeper, low-reactivity locations within retain solutes extended periods, which delays reactions and causes persist at higher conc...
