Semantic interference effects in the picture-word interference (PWI) paradigm have long been assumed to reflect competitive mechanisms during lexical selection, a core component of the speech production system. However, recent observations of facilitative effects have cast doubt on the usefulness of the paradigm for investigating lexicalization, and on the existence of lexical competition in ge...

A mainstay of treatment in haemophilia patients with inhibitors (PWI) is recombinant Factor VIIa (rFVIIa) bypassing agent. The FDA recently approved a new rFVIIa (eptacog beta (EB)) variant that may reduce agent use for on-demand bleeding events (BEs). aim this study was to quantify the clinical and economic value associated EB vs Coagulation eptacog alfa (EA), episodes (BE) occurring PWI. deci...

Is language production dynamically regulated by cognitive control? If so, how domain-general is this process? In two experiments, we studied conflict adaptation, or conflict-driven adjustments of control, in two paradigms: Picture-Word Interference (PWI), which induces linguistic conflict, and Prime-Probe (PP), which induces visuospatial conflict. Exp. 1 tested within-task conflict adaptation s...

BACKGROUND AND PURPOSE Arterial spin labeling (ASL) is a perfusion magnetic resonance imaging (MRI) technique that does not require contrast administration and thus may be more practical in hyperacute stroke than susceptibility-weighted bolus-tracking perfusion-weighted imaging (PWI). However, a threshold for ASL measurement of the ischemic penumbra needs to be determined. METHODS A total of ...

BACKGROUND Quality of life (QoL) in persons with spinal cord injury (SCI) has been found to differ across countries. However, comparability of measurement results between countries depends on the cross-cultural validity of the applied instruments. The study examined the metric quality and cross-cultural validity of the Satisfaction with Life Scale (SWLS), the Life Satisfaction Questionnaire (LI...

Some in vitro experiments have shown that erythropoietin (EPO) increases resistance to apoptosis and facilitates neuronal survival following cerebral ischemia. However, results from in vivo studies are rarely reported. Perfusion-weighted imaging (PWI) and diffusion-weighted imaging (DWI) have been applied successfully to distinguish acute cerebral ischemic necrosis and penumbra in living animal...

OBJECTIVE To report a case of severe vasospasm after subarachnoid haemorrhage (SAH) where "tissue at risk" was identified by magnetic resonance imaging (MRI), and to demonstrate the haemodynamic consequences with either resolution of the perfusion-diffusion mismatch by balloon angioplasty or evolution of an infarct. METHODS A 45 year old women with SAH underwent surgical treatment of a ruptur...

Background and Purpose—In acute stroke, mismatch between lesions seen on diffusion(DWI) and perfusion-weighted (PWI) MRI has been used to identify ischemic tissue before irreversible damage. Nevertheless, the concept of PWI/DWI mismatch is oversimplified and the ischemic tissue metabolic status and outcome are often heterogeneous. Tissue pH, a well-regulated physiological index that alters on d...

This paper describes a new ultrasonic array imaging method for Non-Destructive Testing (NDT) which is derived from the medical Plane Wave Imaging (PWI) technique. The objective is to perform fast ultrasound imaging with high image quality. The approach is to transmit plane waves at several angles and to record the back-scattered signals with all the array elements. Focusing in receive is then a...
