In experiments preliminary to the possible use of carbon-14-labeled Stilbamidine in the treatment of humans with multiple myeloma (2, 9, 26) it was found in normal mice that no abnormal concentra tion of Stilbamidine persisted in any tissue and that over 90 per cent of the injected radioactivity was excreted within a month (20). A tracer dose of C14-labeled Stilbamidine was then given to a hu m...

Background: Diseases caused by microorganisms of the genus Mycobacterium continue to be a serious problem. The cell envelope constitutes up to 60% of the dry weight of lipids. The cell wall of the mycobacterium is essential for their growth and survival in the infected host. The cell wall lipids have been isolated from M. bovis BCG and M. kansasii mycobacterial strains and studied the incorpora...

nine labeled either with C'4 or N'5. Considerable controversy has developed as to which one of these tracer compounds gives an accurate measurement of the “relativeturnover-rate― of the nucleic acids. In order to determine the “absolute turnover rate― of the nucleic acids, it is necessary to know the specific activity of the immediate precursor of the nucleic acids. Since even the ident...

One potent lactic acid bacterial strain C14 with strong antifungal activity was isolated from homemade curd. Based on morphological as well as biochemical characters and 16S rDNA sequence homology the strain was identified as Lactobacillus fermentum. It displayed a wide antimicrobial spectrum against both Gram-positive and Gram-negative pathogenic bacteria, and also against number of food spoil...

Bioluminescent bacteria require myristic acid (C14:0) to produce the myristaldehyde substrate of the light-emitting luciferase reaction. Since both endogenous and exogenous C14:0 can be used for this purpose, the metabolism of exogenous fatty acids by luminescent bacteria has been investigated. Both Vibrio harveyi and Vibrio fischeri incorporated label from [1-14C]myristic acid (C14:0) into pho...

We study spherically symmetric spacetimes in Einstein-aether theory three different coordinate systems, the isotropic, Painlevè-Gullstrand, and Schwarzschild coordinates, which aether is always comoving, present both time-dependent time-independent exact vacuum solutions. In particular, isotropic coordinates we find a class of static solutions characterized by single parameter c14 closed forms,...
