Nuclei were prepared by sucrose sedimentation of liver homogenates from rats given (125)I-labeled triiodothyronine in vivo. The nuclear extract obtained by treatment of the nuclear pellet with 0.4 M KCl contains the [(125)I]triiodothyronine that had been injected in vivo bound to protein(s). The triiodothyronine bound to nuclear protein(s) in vivo does not readily exchange with triiodothyronine...

The kinetic studies of AV-17×8 strongly basic anionite’s oxidative destruction using the Fenton reaction have been carried out. effect process’s temperature and concentration catalysts iron(II) sulfate or copper(II) on oxidation anion-exchange resin with hydrogen peroxide is estimated. With an increase in range 323–348 K, a regular effective rate constant anionite observed when by 1.5 times, – ...

A54145 is a complex of acidic lipopeptide antibiotics which are produced by Streptomyces fradiae and are active against Gram-positive bacteria. The A54145 complex was isolated by adsorption on Diaion HP-20 nonfunctionalized macroreticular resin and/or ion exchange on Amberlite IRA-68 anion exchange resin. Antibacterial factors A, A1, B, B1, C, D, E, and F were obtained in purified form by repea...

background: a laboratory study was conducted to investigate the ability of a special type of strongly basic resin mp500ws for the removal of nitrate from different waters. methods: two different types of point-of-use (pou) devices containing an identical resin were used. mp500ws known as macro porous was used in pou devices for removal of high concentrations of nitrate and sulfate ions from wat...
