OBJECTIVES Cardiovascular involvement is recognized as a poor prognostic factor in systemic sclerosis (SSc). The aim of this study was to evaluate the usefulness of nailfold video-capillaroscopy (NVC), brain natriuretic peptide (BNP) blood level and exercise echocardiography to predict the occurrence of cardiovascular events in SSc. METHODS We prospectively enrolled 65 patients with SSc (age ...

Non-verbal communication (NVC) plays a major role in various aspects of human life (Andersen, 2004; Cameron, 2001; Johnstone, 2008). Children learning their first language come to realize non-verbal communication as their socialization process takes place (Fletcher & German, 1990; Ingram, 1996; Owens, 2001). However, most EFL learners may have little exposure to these non-verbal aspects of comm...

Virtual agents are systems that add a social dimension to computing, often featuring not only natural language input but also an embodiment or avatar. This allows them take on more role and leverage the use of nonverbal communication (NVC). In humans, NVC is used for many purposes, including communicating intent, directing attention, conveying emotion. As result, researchers have developed emul...

non-verbal communication (nvc) plays a major role in various aspects of human life (andersen, 2004; cameron, 2001; johnstone, 2008). children learning their first language come to realize non-verbal communication as their socialization process takes place (fletcher & german, 1990; ingram, 1996; owens, 2001). however, most efl learners may have little exposure to these non-verbal aspects of ...

OBJECTIVES Systemic sclerosis (SSc) is characterized by altered microvascular structure and function. Nailfold videocapillaroscopy (NVC) is the tool to evaluate capillary morphological structure and laser-Doppler Blood flowmetry (LDF) can be used to estimate cutaneous blood flow of microvessels. The aim of this study was to investigate possible relationships between capillary morphology and blo...

BACKGROUND Neurovascular coupling (NVC) is the mechanism whereby an increase in neuronal activity (NA) leads to local elevation in cerebral blood flow (CBF) to match the metabolic requirements of firing neurons. Following synaptic activity, an increase in neuronal and/or astrocyte Ca2+ concentration leads to the synthesis of multiple vasoactive messengers. Curiously, the role of endothelial Ca2...

This retrospective, observer blinded case-control study aims to compare the prevalence of neurovascular conflicts (NVCs) of the vestibulocochlear nerve and the anterior inferior cerebellar artery (AICA) in patients presenting with clinical signs of acute vestibular neuritis with and without subsequent objective vestibular function loss (VFL). 58 acute cases of clinically suspected acute vestibu...

OBJECTIVE To describe the anatomical characteristics and patterns of neurovascular compression (NVC) in patients suffering trigeminal neuralgia (TN) by 3D high-resolution magnetic resonance imaging (MRI) method and image fusion technique. METHODS The anatomic structure of trigeminal nerve, brain stem and blood vessel was observed in 100 consecutive TN patients by 3D high resolution MRI (3D SP...
