Carbonado is a porous polycrystalline diamond rock found in central African and Brazilian placer deposits. It contains unsupported radiogenic isotopes of He, Ne, Kr, Xe, and Pb. Here we show that these, and the radiation-related defects introduced to

A technique for the rapid preparation of mitochondria from rat liver is described. Tissue fractionation is performed by a single centrifugation step with a discontinuous Percoll density gradient. Total preparation times of 5-6 min are achieved by usi

Glucose transport in rat adipocytes was studied by monitoring the conversion of [1-14C]-glucose to 14CO2 in a system where glucose transport was made rate-limiting by increasing the flux through the pentose phosphate pathway with phenazine methosulph

The effect of ionophore A23187 on cellular Ca2+ fluxes, glycogenolysis and respiration was examined in perfused liver. At low extracellular Ca2+ concentrations (less than 4 microM), A23187 induced the mobilization of intracellular Ca2+ and stimulated

Exposure of perfused livers of fed rats to 60 mM K+ induces rapid responses in the Ca2+-sensitive metabolic events, glycogenolysis, cytoplasmic and mitochondrial NADH/NAD ratios and octanoate oxidation. All increase within 45 s of K+ addition. Metabo

Phenylephrine (1.5 x 10(-6) M) administered to perfused livers from fed rats gave rise to a rapid, parallel increase in oxygen uptake and glucose output. The time of onset for oxygen uptake was 9.9 +/- 0.4 s following phenylephrine administration, an

An indirect method for obtaining a reliable measure of the rate of glucose transport into adipocytes is described. Evidence is presented that altered levels of 3':5'-cyclic AMP can influence the transport of glucose into adipocytes. When cyclic AMP l

Phenylephrine (2.0 microM) induces an alpha 1-receptor-mediated net efflux of Ca2+ from livers of fed rats perfused with medium containing physiological concentrations (1.3 mM) of Ca2+. The onset of efflux (7.1 +/- 0.5 s; n = 16) immediately precedes

Glutamate (5 mM) inhibited glucose conversion to fatty acids by approximately one-third in adipocytes from fed rats. This inhibition was significantly less in the presence of pyruvate or 2-oxoglutarate. After incubation of adipose tissue from fed rat

The binding and uptake of [3H]adrenaline by the intact perfused rat liver was investigated. We showed that the administration of [3H]adrenaline to liver resulted in the rapid uptake of the radioligand, and that such uptake was independent of any Ca2+
