Preparation of radioactive iodocasein.
We have recently prepared iodocasein containing radioactive iodine (1’31) for use in studies, to be described in detail elsewhere, on the metabolism of calorigenic substances in human beings. The procedure followed was, in general, that of Reineke and Turner (1,2) except for modifications necessitated by the incorporation and handling of Pal. These modifications shorten the procedure somewhat a...
متن کاملPreparation of solid water-equivalent radioactive standards.
The use of a superabsorbent polymer to prepare water-equivalent volume standards by solidification without the need of irradiation to effect the polymerization process, is described. Less than 40 g of the polymer is needed to solidify 1 litre of solution. Monte Carlo simulations of the gamma-ray escape probability indicate that the mixture is water-equivalent to better than 1.0%. During prepara...
متن کاملGibberellins
What are they? The gibberellins make up a family of small organic compounds derived from a common 20-carbon precursor. They regulate growth and development in plants and their chemical structure superficially resembles that of steroid hormones. So far, more than 100 gibberellins have been identified. Fortunately, any one plant species produces only a few of the known gibberellins. Furthermore, ...
متن کاملPreparation of radioactive carbon-labeled sugars by photosynthesis.
Carbohydrates, glucose, fructose, sucrose, and starch, labeled in all carbon positions with C14, are useful for the study of intermediate metabolism in living organisms and for many other purposes. Two papers dealing with the synthesis of labeled carbohydrates have already appeared (1, 2), but no detailed methods of preparing the above carbohydrates are available. It is the purpose of this pape...
متن کاملThe Effect of Fermented Papaya Preparation on Radioactive Exposure.
Exposure to ionizing radiation causes cellular damage, which can lead to premature cell death or accumulation of somatic mutations, resulting in malignancy. The damage is mediated in part by free radicals, particularly reactive oxygen species. Fermented papaya preparation (FPP), a product of yeast fermentation of Carica papaya Linn, has been shown to act as an antioxidant. In this study, we inv...
