Abstract:

Three studies were conducted to determine whether the elevated plasma and HDL cholesterol levels observed in copper-deficient rats could be explained by the interaction of ¹²⁵I-HDL subfractions with liver membrane preparations in vitro. Rats from all studies were randomly divided into two dietary treatments, copper-deficient and adequate (0.7 mg and 8.0 mg Cu/kg diet, respectively). Deionized water and diet were provided ad libitum. After eight weeks, rats were exsanguinated, membranes prepared from livers, and plasma high density lipoproteins (HDL) isolated by ultracentrifugation and agarose

Abstract:

This study was designed to examine the influence of Cu deficiency on the binding, uptake, and degradation of apolipoprotein E-free high density lipoproteins (apo E-free HDL) in cultured rat hepatic parenchymal cells. The binding of apo E-free HDL during time course studies was slightly but significantly increased in cells derived from Cu-deficient rats. In saturation studies, the amount of surface-bound apo E-free HDL appeared to be saturable, although no difference was observed between Cu-deficient and adequate animals. The amount of total and specific cell-associated uptake of apo E-free HDL

Abstract:

Three studies were designed to investigate the influence of dietary copper (Cu) on liver morphology, aortic integrity, lipid composition of lipoproteins, fatty acid profile of hepatic lipids, as well as in vivo hepatic fatty acid synthesis. Animals were randomly assigned to two dietary Cu treatments (deficient and adequate). Reductions in body weight, liver Cu content, and hematocrit, as well as elevations in liver weight and plasma volume were observed in animals fed Cu-deficient diet. Electron micrographs suggest that the Cu-deficient liver parenchymal cells contain a higher number of mitoch

Cependant, les fluctuations de concentration et de pression des propergols (tels que l’oxygène ou l’hydrogène liquide) à la surface de la paroi favorisent l’endommagement de l’alliage, en particulier si la paroi n’est pas en permanence couverte d’une pellicule

Abstract:

Long lived radioactive species such as ¹²⁹I⁻ and ⁹⁹TcO₄⁻ are formed as by-products of nuclear fission. These species have extremely long half-lives (1.5 million and 211,000 years respectively), are biologically assimilating and due to their anionic nature, can move freely within a geosphere. Historical disposal methods for active species are no longer considered acceptable to the general public and other ways in which to treat the waste are being explored. One remove and concentrate method to remove radioactive species from the biosphere is using alkaline-resistant materials which trap active
