in a greenhouse experiment, the effects of glomus intraradices and indigenous mycorrhizal isolates from soils under plow and no-till treatments on the uptake of 32p placed at 1, 2.5 and 4 cm from the roots of white clover (trifolium repens) in 23, 37 or 46 days after planting were compared.spores of the indigenous fungi were mostly a mixture of glomus mossea, g. clarum, g. caledonium and g....

Small streams in urbanized rural areas receive loads of P from various, often episodic, sources. This paper addresses, through a tracer test with 32P, retention and transport pulse input phosphorus 2.6 km long stretch channelized second-order lowland stream. Tritiated water was introduced alongside the 32P-labelled ortophosphate order to isolate influence hydrodynamic factors on behavior. Trace...

background: recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. in this study a unique radioactive source for intra vascular brachytherapy (ivbt) was investigated. the two-dimensional dose distribution in water for a 32p ivbt stent has been calculated. the pure beta emitter source 32p has been coated on p...

Insulin stimulates hexose transport and phosphorylation of the insulin receptor in monolayer cultures of intact 3T3-L1 adipocytes. To assess the phosphorylation state of the receptor in situ, cells were equilibrated with [32P]orthophosphate and then disrupted under denaturing conditions which preserved the phosphorylation state of the receptor established in the cell. The insulin receptor, isol...

The labeling of the protein moiety of the sarcoplasmic calcium transport ATPase by fluorescamine suppresses calcium transport, calcium dependent ATPase activity, protein phosphorylation by [gamma-32P]ATP and [32P]phosphate at different extent of amino group substitution. For the hydrolysis of para nitrophenylphosphate by the calcium transport ATPase, it is shown that the relationship between th...

Cardiac microsomes were incubated with [gamma-32P]ATP and a cardiac adenosine 3':5'-monophosphate (cyclic AMP)-dependent protein kinase in the presence of ethylene glycol bis(bets-aminoethyl ether)-N,N'-tetraacetic acid. After solubilization in sodium dodecyl sulfate and fractionation by polyacrylamide gel electrophoresis, a single microsomal protein component of approximately 22,000 daltons wa...

unlabelled glucose 1-phosphate was added and changes in the concentration of glucose 1-phosphate and glucose 1-[32P]phosphate activity were followed as the system relaxed back towards equilibrium. The results from a number of such experiments at low concentrations of glucose monophosphates are shown in Fig. 1. With 32P-labelled substrates, co-transport of glucose I-[32P1phosphate into glucose 6...

The effects of vitamin D on transport of inorganic phosphate into and across rat intestinal mucosa in vifro were studied, and the results used to interpret observations on incorporation of 32P-labeled phosphate into mucosal lipid, protein, and nucleic acids. Vitamin D given to intact rats increases phosphate transport in vifro selectively in the direction mucosa to serosa. The sterol in vivo ac...

Summtiizary. Primary roots of solution--grown, 5-day-old or 6-day-old seedlings of corn (Zea mays L.) 10 to 14 cm in length were used to study radial salt trtansport. Measurements were made of the volume of root pressure exudation, salt concentration of the exudate, and rate of salt movement into the xylem exudate. The 32p uptake, 09 consumption, and dehydrogenase activity of the root cortex an...
