Progressive pediatric glomerularnephroses can lead to tubulointerstitial fibrosis (TIF) and chronic kidney disease (CKD). Fractional excretion of magnesium (FEMg) is a sensitive tubular function test (Ref). FEMg correlates positively with TIF (Ref). The purpose of the study was to correlate FEMg with renal histolopathology in pediatric glomerular nephrosis (GN). Sixty three cases, between 1-12 ...

Abstract Dehumanization is routinely invoked in social science and law as the primary factor explaining how propaganda encourages support for, or participation in, violence against targeted outgroups. Yet primacy of dehumanization increasingly challenged by apparent influence revenge on collective violence. This study examines critically various audiences. Although previous research stresses da...

This study investigated embouchure-related muscle activities and related facial skin movement in trained French horn players. In relation to pitch and intensity of tone produced, amplitude of surface electromyogram (EMG) from five selected facial muscles and related facial skin kinematics were examined during preand post-attack phases. There was no difference in EMGs and facial kinematics betwe...

In the current study, electroencephalography (EEG) was recorded simultaneously with facial electromyography (fEMG) to determine whether emotional faces and emotional scenes are processed differently at the neural level. In addition, it was investigated whether these differences can be observed at the behavioural level via spontaneous facial muscle activity. Emotional content of the stimuli did ...

Background: The electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful.Objective: Removing electrocardiogram contamination from electromyogram signals.Methods: In this paper, the clean electromyogram signal, electrocardiogram artifact and e...

The crystal structure of the complex pi-AlFeMgSi phase, which was previously thought to have the composition Al(8)FeMg(3)Si(6), has been investigated. Microprobe analysis revealed that the phase has a different composition, Al(9)FeMg(3)Si(5). The space group was determined and confirmed to be P62m with the use of parallel-beam electron diffraction (SAD) and convergent-beam electron diffraction ...

In the recent past, there has been an increasing trend to use blind source separation (BSS) or independent component analysis (ICA) algorithms for biomedical data. This paper reviews the concept of ICA and demonstrates its usefulness and limitations in the context of surface electromyograms (sEMG) related to hand movements and facial muscles. In the first experiment ICA has been used to separat...

This study investigated activity of the embouchure-related orofacial muscles during pre- and postattack phases of sound production by 10 trained French-horn players. Surface electromyogram (EMG) from five selected facial muscles, and related facial skin kinematics were examined in relation to pitch and intensity of a tone produced. No difference in EMGs and facial kinematics between the two pha...

This paper presents a new algorithm to translate electromyogram (EMG) signals, produced during facial muscle contractions, into computer cursor actions. These cursor actions are: left, right, up, down and left-click. The translation is performed in real-time and the classification of the EMG signals is based on features derived from the spectral analysis of the electromyograms. We have sought t...
