Hemodynamic adjustments during breath-holding in trained divers.
Eur J Appl Physiol

Purpose: Voluntary breath-holding (BH) elicits several hemodynamic changes, but little is known about maximal static immersed-body BH. We hypothesized that the diving reflex would be strengthened with body immersion and would spare more oxygen than maximal dry static BH, resulting in a longer BH duration.
Methods: Eleven trained breath-hold divers (BHDs) performed a maximal dry-body BH and a maximal immersed-body BH.
Value of impedance cardiography in patients studied for pulmonary hypertension.

October 2011
Division of Pulmonary, Critical Care and Sleep Medicine, Cleveland Clinic, 9500 Euclid Avenue A-90, Cleveland, OH 44195, USA.
The aim of this study was to evaluate the accuracy and precision of impedance cardiography as a method for noninvasive hemodynamic evaluation of patients with pulmonary hypertension (PH). We performed a prospective and blinded study of patients who underwent right heart catheterization (RHC) for evaluation of known or presumed PH at the University of Florida from August 2009 to March 2010. The cohort consisted of a total of 39 patients (age = 57 ± 14 years, 87% women) with presumed (23%) or confirmed PH (77%) of different etiologies.

Material And Methods: A 30-60% replacement of circulating plasma for salt or dextran using PF-05 unit has been performed in 324 patients 35-79 years of age with recurrent myocardial infarction and angina pectoris. A total of 520 PR procedures were performed.
The structure of the acidic exopolysaccharide of Pseudomonas marginalis strains PF-05-2 and PM-LB-1.
Carbohydr Res
May 1990
Department of Agriculture, North Atlantic Area, Philadelphia, PA 19118.
The structure of an acidic exopolysaccharide of two strains of Pseudomonas marginalis, a bacterium which causes soft rots of various vegetables, has been determined to consist of a repeating unit of: ----4) beta-D-Manp-(1----3)alpha-D-Glcp-(1----4)alpha-L-Rhap-(1-. The glucose is pyruvated at O-4 and O-6 and the mannose is acetylated at either O-2 or O-3.
