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 ...

An endogenous ouabainlike compound (OLC) has been purified from human plasma, and mass spectrometry has shown it to be indistinguishable from plant-derived ouabain. This human OLC was tested for its effects on evoked tension in guinea pig left atria and aortic rings. The tissues were incubated at 37 degrees C in bicarbonate-buffered physiological salt solution gassed with 95% O2-5% CO2. In atri...

OBJECTIVE To evaluate data from an online chlamydia testing program (OLC) developed to increase young people's access to testing for chlamydia, the most commonly notified disease in Australia and Western Australia, with a high proportion of notifications among young people (< 30 years). DESIGN AND SETTING The OLC was launched in February 2010, and our study covers the period February 2010 to ...

background: the concept of organizational learning capability (olc) emphasizes the importance of facilitating factors for organizational learning or the organizational propensity to learn. consequently, measures of olc have traditionally determined their dimensions or facilitating factors based on the literature. the purpose of this study was to validate and evaluate the factorial construction ...

BACKGROUND Ventilation with low tidal volume (VT) is well recognized as a protective approach to patients with acute respiratory distress syndrome (ARDS), but the optimal level of positive end-expiratory pressure (PEEP) remains uncertain. This study aims to evaluate two protective ventilatory strategies sequentially applied in patients with early ARDS. METHODS In this prospective cohort study...

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...
