The developmental onset of three homocysteine metabolizing enzymes in the rat conceptus was investigated. Cystathionine-beta-synthase and methionine synthase were assayed from day 10 to day 20 of gestation in decidual and placental tissue, from day 10 to day 12 of gestation in embryonic tissue, from day 14 to day 20 of gestation in fetal liver and from day(More)

Methanol:5-hydroxybenzimidazolylcobamide methyltransferase from Methanosarcina barkeri has been purified to approximately 90% homogeneity by ion-exchange chromatography on DEAE-cellulose and QAE-A50 Sephadex columns. The molecular weight, estimated by gel electrophoresis, was found to be 122,000, and the enzyme contained two different subunits with(More)
Thales has successfully designed and built a high power, long pulse, high efficiency UHF klystron prototype for proton linac sources. The TH2182 reference operates in horizontal position and delivers up to 1.5MW peak and 150 kW average RF power at 704 MHz, in 1.7 ms RF pulse, and with an efficiency of 65%. Details of the design and test results will be(More)
