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 thyroxine dose o... 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 negligible radioactivity was recovered in glycogen or
tissue lipid. Comp... 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 received an infusion or
intragast... hiện toàn bộ
