On the influence of extracellular fluid volume expansion on bicarbonate reabsorption in the rat.
Bicarbonate reabsorption is classically regarded as a rate-limited process characterized by saturation kinetics. The tubular maximum (Tm), however, varies with glomerular filtration rate. Thus bicarbonate reabsorption, in common with sodium reabsorption, is characterized by glomerulo-tubular balance. The examination of bicarbonate reabsorption is accomplished using the bicarbonate titration tec...
متن کاملFetal Lambs
Morphologic analyses of lungs from infants who died of severe aortic stenosis shortly after birth have shown increased pulmonary vascular smooth muscle and an increased number of pulmonary resistance vessels. These findings have been thought to be caused by in utero pulmonary venous, pulmonary arterial or right ventricular hypertension. To study this problem in the fetus, we created aortic sten...
متن کاملDecline in lung liquid volume before labor in fetal lambs.
The volume of liquid in the fetal lung depends on the amount of liquid secreted across the pulmonary epithelium and the amount flowing through the trachea. Lung liquid volume (V1) and secretion rate Vs) were determined using an indicator-dilution technique, while tracheal flow rate (Vtr) was measured simultaneously with a bubble flowmeter. Least-squares regression analysis showed that in 10 chr...
متن کاملThe influence of fetoabdominal volume conduction on the fetal MCG
Fetal magnetocardiograms (MCG) can be measured non-invasively. From these measurements the duration of the various waves in the fetal cardiogram can be obtained as well as the fetal heart rate. Hence, the fetal MCG can, for instance, be used to classify arrhythmias. However, the amplitudes within the measured cardiogram depend on the fetoabdominal anatomy. For instance, the position of the meas...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
