Measurement of rates of cholesterol synthesis using tritiated water.
Rates of sterol synthesis in various tissues commonly are assessed by assaying levels of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase on isolated microsomes or by measuring the rates of incorporation of various 14C-labeled substrates or [3H]water into cholesterol by whole cell preparations in vitro or by the tissues of the whole animal in vivo. While measurement of activities of HMG-CoA r...
متن کاملPhotosynthate transport using tritiated water.
The exchange of HTO with aerial portions of the soybean was studied under a variety of conditions. When fed to a lone leaf or leaflet in a saturated air atmosphere (all other leaves and the growing point having been excised), the HTO profile virtually ceases at a distance of 2 cm from the feeding chamber in the photosynthetic plant, but is greater and more extensive in the unilluminated plant. ...
متن کاملEntrapment–D-(+)-Glucose Water Nanodroplet: Synthesis and Dynamic Light Scattering
In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...
متن کاملBody water estimation in the newborn using tritiated water.
Of all the substances used for the estimation in vivo of total body water content, the most attractive are the isotopes of hydrogen, since they enter into all the metabolic processes involving water and have no selective secretion or storage. Deuterium was the first substance used for body water estimation in vivo (Hevesy and Hofer, 1934) and is preferable to tritium because it is not radioacti...
متن کاملCytological damage produced in the mouse testes by tritiated thymidine, tritiated water and x-rays.
Irradiation of the mouse testes was carried out using internally distributed tritium from injected tritiated thymidine and tritiated water and also using external whole body irradiation with 200 kVp X-rays. The inability of intermediate spermatogonia to divide twice and produce resting primary spermatocytes was used as a criterion of biological damage and the following conclusions were reached:...
