Effects of physiological levels of thyroxine in vivo on respiration and phosphorylation in rat liver fractionsAmerican Physiological Society - Tập 197 Số 2 - Trang 370-376 - 1959
Alan S. Fairhurst, Jane Roberts, Robert E. Smith
Liver mitochondrial systems of varying heterogeneity with respect to microsomal-soluble components were isolated from thyroidectomized and normal rats given l-thyroxine at various dose levels (0, 3, 10, 30, 100, 500 and > 500 µg daily) for 14 days. Degree of homogeneity of fractions was checked by electron and light microscopy. Determinations were made as functions of fraction and thyr...... hiện toàn bộ
Pyruvate metabolism in the perfused rat heartAmerican Physiological Society - Tập 205 Số 5 - Trang 971-976 - 1963
John R. Evans, Lionel H. Opie, Albert E. Renold
The metabolism of C14-labeled pyruvate in the isolated heart was studied in a closed recirculation system. Decarboxylation was the major fate of pyruvate-1-C14 and increased according to the concentration of pyruvate in the perfusion fluid. Lactate formation accounted for most of the remainder of the pyruvate-1-C14 uptake and ...... hiện toàn bộ
Role of bile and pancreatic juice in cholesterol absorption and esterificationAmerican Physiological Society - Tập 206 Số 1 - Trang 223-228 - 1964
C.R. Borja, George V. Vahouny, C. R. Treadwell
Absence of bile and pancreatic juice in the intestinal tract totally abolished absorption of cholesterol-4-C14 into thoracic duct lymph. Similarly, intestinal cholesterol esterase activity approached zero in animals lacking both bile and pancreatic juice. Intestinal cholesterol esterase could still be demonstrated in animals deprived of pancreatic juice, but which rec...... hiện toàn bộ
