S106 is a bipolar nebula illuminated and excited by a central star called S106 IR. Depending on its distance (literature values range from 500 pc to 5.7 kpc) this star is of late O to early B spectral type. There is evidence that S106 is physically associated with the molecular cloud complex of Cygnus X. The bipolar nebula is the dominant feature in an(More)
Previous studies from this laboratory have demonstrated that the redistribution of blood volume and concomitant central hypervolemia induced by water immersion to the neck (NI) results in a significant natriuresis, kaliuresis, and diuresis. The NI model was utilized to assess the role of "effective volume" and hyperaldosteronism in the impairment of sodium(More)
The ability of short-term furosemide administration to alter intrarenal hemodynamics and to modify the clinical course of acute renal failure was assessed in six patients 2 to 9 days after the onset of acute renal failure. Following renal arterial catheterization, the intraarterial administration of furosemide at a dose of 9.6 mg/min for 30 minutes failed(More)
The relationship between systemic and renal hemodynamics was studied in 20 patients with advanced cirrhosis of the liver. Cardiac output was assessed by an indicator dilution technique, and both mean renal blood flow and intrarenal blood flow distribution were determined by the 133Xe washout method. Ten patients had elevated cardiac outputs (7.14 to 13.58(More)
Color and lightness constancy with respect to changing illumination was studied with three different perceptual tasks: ranking of colored papers according (1) to their lightness and (2) to their chromatic similarity in photopic, mesopic, and scotopic states of adaptation, and (3) recognition of remembered colored papers after changes of illumination in(More)
OBJECTIVE Although the clinical efficacy of cognitive behaviour therapy (CBT) has been established for patients with schizophrenia, the data on effects on quality of life (QoL) are lacking. The purpose of the present study was therefore to compare the effects of a brief group CBT and a group psychoeducational (PE) programme in patients with schizophrenia on(More)
