The effect on the right atrial pressure and oxygen saturation of expansion of the plasma volume by rapid infusion of 500 ml. 5 per cent glucose has been studied in I4 patients with recent uncomplicated cardiac infarction, and in 5 patients with cardiogenic shock. The findings are contrasted with the effect of intravenousfrusemide (40 mg.) in 8 patients with recent cardiac infarction complicated...

(15)N longitudinal relaxation rates are extensively used for the characterization of protein dynamics; however, their accurate measurement is hindered by systematic errors. (15)N CSA/(1)H-(15)N dipolar cross-correlated relaxation (CC) and amide proton exchange saturation transfer from water protons are the two main sources of systematic errors in the determination of (15)N R1 rates through (1)H...

The relations between the concentration of deoxycholic acid (DCA), the cholesterol saturation index, and the nucleation time in gall bladder bile were measured to determine the role of DCA in bile in the pathogenesis of cholesterol gall stone disease. Bile was obtained from patients with cholesterol gall stones (n = 30), subjects without gall stones (n = 35), and patients with pigment gall ston...

Background: The delivery room oxygen saturation (SpO2) monitoring in neonates is based on studies term infants. Study of preductal-postductal SpO2 gradient healthy preterms immediately after birth will help follow-up an abnormal gradient, rationalizing therapy, and early identification congenital cyanotic heart disease. Aims Objectives: initially low gradually increases to normal newborns postn...

Steady-state dissolution rates of diopside are measured as a function of solution saturation state using a titanium flow-through reactor at pH 7.5 and temperature ranging from 125 to 175 degrees C. Diopside dissolved stoichiometrically under all experimental conditions and rates were not dependent on sample history. At each temperature, rates continuously decreased by two orders of magnitude as...

This investigation deals with a mathematical model for a distribution transformer including saturation effect. To this end, the equations related to a three phase transformer are specified and the effect of an inter-turn fault is included. Naturally by applying an inter-turn fault the inductance and resistance matrix will change. Thus, unknown quantities of inductances and resistances for compl...

abstract background: stressors in the intensive care unit (icu) impair patients’ comfort, excite the stress response, and increase oxygen consumption in their body. non‑medical interventions are recommended by several studies as a treatment to improve comfort in the icu patients. sensory stimulation is one of the most important interventions. since arterial blood oxygen saturation is an importa...
