The bile coming at one time from different portions of the liver of the dog has nearly the same amount of pigment per cubic centimeter. With this determined we have studied the power of the gall bladder to concentrate bile directed to it, using as criterion the pigment strength of a sample collected throughout the period of experiment from a duct branch. The extent and rapidity of the concentra...

Despite previous reports of no apparent photorespiration in C. , plants based on measurements of gas exchange under 2 versus 21% O, at varying [CO,], photosynthesis in maize (Zea mays) shows a dual response to varying [O,]. l h e maximum rate of photosynthesis in maize i s dependent on 0, (approximately 10Y0). lhis O2 dependence is not related to stomatal conductance, because measurements were...

Boron doped TiC shows improved optical selectivity for concentrating solar power applications.

Polyuria is a frequent symptom of hyperparathyroidism. Impairment of renal concentrating ability, often out of proportion to other signs of renal insufficiency, has been noted in patients with hyperparathyroidism (1-3) as well as in patients and animals with hypercalcemia due to other causes (4-6). In many patients with hyperparathyroidism, extensive deposits of calcium in the renal parenchyma,...

The capacity of patients with cirrhosis of the liver to produce a dilute urine after a water load has been extensively investigated (1, 2). The concentrating ability of these patients has not been carefully studied, although the assumption has been made that a defect exists (1, 3). The present studies describe the characteristicsof the concentrating system in patients with cirrhosis and attempt...
