BACKGROUND Deep hypothermic circulatory arrest (DHCA) is commonly used for complex cardiac operations in children, often with selective cerebral perfusion (SCP). Little data exist concerning the real-time effects of DHCA with or without SCP on cerebral metabolism. Our objective was to better define these effects, focusing on brain oxygenation and energy metabolism. METHODS Piglets undergoing ...

Equilibrium binding studies show that 6 atoms of calcium are bound by the dimeric molecule of the sarcoplasmic calcium-binding protein (SCP) from crayfish. SCP exhibits positive cooperativity in calcium-binding for four sites, as indicated by increasing intrinsic binding constants (1 to 5 x 10” M-l), and negative cooperativity for the other two sites (decreasing constants from 5 to 0.8 x lo7 M-...

Sign change problem (SCP) in multivariate Quantitative Structure-Activity/Property Relationships (QSAR/QSPR) is the inconsistency in the direction of association between molecular descriptors and the dependent variable. Sign change is observed when the signs of the elements of the reference vector (correlation vector for the data set obtained from variable selection) are compared to the signs o...

Behavioral psychophysiological treatment entailing Slow Cortical Potential (SCP) biofeedback training and behavioral self-control training was conducted with a 27-year-old male epileptic patient (seizures for 23 years) with Wechsler IQ 64 who underwent callosotomy. The patient had 12/week secondary generalized tonic-clonic seizures. The treatment, consisting of 43 SCP training sessions and 22 b...

Although X-ray absorption spectroscopy (XAS) was conceived in the early 20th century, it took 60 years after advent of synchrotrons for researchers to exploit its tremendous potential. Counterintuitively, are now developing bench type polychromatic sources that less brilliant measure catalyst stability and work with toxic substances. XAS measures spectra electrons X-rays eject from tightly boun...

Self-efficacy in essential hypertension can be measured using scales, such as the "Hypertension Self-Care Profile" (HTN-SCP) questionnaire. It assesses "Behavior", "Motivation", and "Self-efficacy" in 3 domains, respectively. This study aimed to validate the Mandarin version of HTN-SCP instrument (HTN-SCP-Mn) targeted at patients of Chinese ethnicity with hypertension.Our study recruited Chines...

The study aimed to explore the predictive value of neuropsychological tests within the context of acquisition of slow cortical potential (SCP) self-control, a technique which has beneficial effects on seizure frequency in epilepsy. Patients with epilepsy who successfully achieved SCP control had longer digit or block-tapping spans than less successful patients. Patients who showed a better lear...

We investigated the relationship between three electrophysiological indices of response anticipation in a spatial delayed response task with a low and high memory load manipulation: a slow cortical potential (SCP), theta desynchronization, and upper alpha synchronization. Individual differences in these three measures were examined in 531 adult twins and siblings. Heritability of the SCP at occ...

SCP-ECG (Standard Communications Protocol for Computer-Assisted Electrocardiography) is a signalspecific format drawn by the European Committee for Standardization with the goal to be widely used in the ECG field. According to it, a software prototype has been developed and tested in a complex clinical setting. The program extracts information related to the patient, the global measurements, th...

Findings on depressive patients indicate that depressives have electrophysiological characteristics similar to those of schizophrenics, in that they exhibit reduced Contingent Negative Variation (CNV) amplitudes and more distinct Postimperative Negative Variations (PINVs) than normal controls. In a biofeedback experiment, 8 medicated male inpatients with the DSM III-R diagnosis of "Bipolar Diso...
