The electrical membrane potential (delta psi) of chicken embryo fibroblasts in tissue culture was determined to be -30.5 +/- 2.9 mV as measured by distribution of the lipophilic [3H]tetraphenylphosphonium cation (Ph4P+). Stimulation of the electrogenic activity of the Na+,K+-ATPase by the ionophore monensin induces a hyperpolarization of approximately 47 mV and a new delta psi of -77.3 +/- 5.7 ...

Background and Objectives: Deficits in oligodendrocytes have been consistently reported in the brains of patients with schizophrenia and include alterations in the clustering pattern of oligodendrocytes. Recently it has been shown that oligodendrocyte progenitors proliferate in the adult mammalian brain to form oligodendrocyte clusters (OlC). We previously found a deficit of oligodendrocytes in...

The purpose of this paper is to present a C2 holonic reference architecture (HRA) that is applicable to Navy maritime headquarters (MHQ) with maritime operations center (MOC) for assessing, planning and executing multiple missions and tasks across a range of military operations. The control architecture consists of three levels: strategic level control (SLC), operational level control (OLC) and...

This study examines the moderating effect of organisational life cycle (OLC) stages on the association between the approach to using controls (interactive versus diagnostic) with organisational performance. Analysis is conducted in respect to Miller and Friesen’s (1984) organisational life cycle (OLC) stages (birth, growth, maturity, and revival). Data were collected by a survey questionnaire f...

OBJECTIVE Ventilation according to the open lung concept (OLC) consists of recruitment maneuvers, followed by low tidal volume and elevated positive end-expiratory pressure (PEEP). Elevated PEEP is associated with an increased right ventricular afterload. We investigated the effect of OLC ventilation on right ventricular outflow impedance during inspiration and expiration in patients after card...

Ouabain, an inhibitor of the sodium pump, has been identified as a constituent of bovine adrenal glands. We were interested whether the release of this cardiotonic steroid is stimulated by physical exercise. Hence, athletes and healthy dogs were subjected to ergometry. Ouabain-like compound (OLC) was measured in venous blood by enzyme-linked immunosorbent assay as well as by Rb uptake inhibitio...
