The levels of DNA, RNA and Protein were estimated in cerebral hemisphere, cerebellum and brain stem of male albino rats with Nuvacron (0, 0, dimethyl-0-1 methyl 3-methylamino-3-oxe-1-propenyl phosphate) 4 mg/kg body weight intraperitoneally (i.p.) daily for 10 days. The daily i.p. dose of Nuvacron depleted the level of DNA and protein in all brain regions. Increased level of RNA was observed in...

1. We have investigated the effects of ethanethiol, methanethiol and dimethyl sulphide on some metabolic processes of isolated rat hepatocytes, isolated mitochondria from liver and brain and ox-heart submitochondrial particles. 2. Ethanethiol, but not dimethyl sulphide, inhibited both gluconeogenesis and ureogenesis from various substrates in rat hepatocytes, depressed cellular ATP content and ...

DESCRIPTION Zopiclone is a fine white or slightly cream crystalline powder with a melting point of 176-178°C. It is practically insoluble in acetone, soluble in dimethyl formamide and 0.1N hydrochloric acid and freely soluble in chloroform and dichloromethane. Imovane tablets contain 7.5 mg of the active ingredient zopiclone. The tablets also contain lactose, calcium hydrogen phosphate, wheat s...

The interactions among neutral polymer polyacrylamide (PAM) and the biosurfactant Surfactin and four betaines, N-dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (SDDAB), N-tetradecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (STDAB), N-hexadecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate (SHDAB), and N-dodecyl-N,N-dimethyl-2-ammonio-acetate (C12BE), in phosphate buffer solution (PBS) have been...

The problem of bacteria resistance to many known agents has inspired scientists and researchers to discover novel efficient antibacterial drugs. Three rapid, clean, and highly efficient methods were developed for one-pot synthesis of 7-(aryl)-10,10-dimethyl-10,11-dihydrochromeno[4,3-b]chromene-6,8(7H,9H)-dione derivatives. Three components are condensed in the synthesis, 4-hydroxycoumarin, 5,5-...

A new gas chromatographic method for the determination of sulfate was developed. In this method, sulfate was quantitatively converted to a volatile derivative, dimethyl sulfate, by a two-step procedure. First, sulfate was converted to silver sulfate by reaction with silver oxide, and then to dimethyl sulfate by reaction with methyl iodide. The derivative was analyzed by gas chromatography. Meth...
