A Unified Radiometric Assay System For The Gaba-Glutamate Regulating Enzymes, Robert C. Dinwoodie May 1978

A Unified Radiometric Assay System For The Gaba-Glutamate Regulating Enzymes, Robert C. Dinwoodie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was to develop a single assay system for the enzymes which regulate GABA and glutamate concentrations in brain and nerve tissue. Since all the enzymes produce L-glutamate, their activities were measured by coupling them to L-glutamate decarboxylase. Enzymatic activity was determined by measuring the release of co2 from radioactive substrates. The glutamate decarboxylase was obtained from a commercial acetone powder by simplifying existing procedures. The glutamate decarboxylase produced was of sufficient purity to be used in the coupled assays, which were checked with commercial preparations of each enzyme, where available, and with crude brain homogenates. …


Non-Parental-Type Recombinants In Crosses Between Different Restriction-Modification Systems In Salmonella, Mary Ball May 1978

Non-Parental-Type Recombinants In Crosses Between Different Restriction-Modification Systems In Salmonella, Mary Ball

Loma Linda University Electronic Theses, Dissertations & Projects

Many new restriction-modification (R-M) system which are closely linked to serB and allelic to the hsdSB system of S. typimurium occur in different Salmonella serotypes. In PI transduction studies with these systems, recombinants were isolated which fell into one of three classes with reference to their specific restriction phenotype. Recombinants that restricted like the donor, recombinants that restricted like the recipient and recombinants that had lost the ability to restrict. This latter group having lost the recipient SB restriction without gaining the specific donor restriction and here called "zero recombinants,” were of special interest and were investigated.

Zero recombinants …

Investigations Of Possible Allelopathic Effects Of Lycopodium Flabelliforme (Fern.) Blanch., Joan Macuszek Jan 1978

Investigations Of Possible Allelopathic Effects Of Lycopodium Flabelliforme (Fern.) Blanch., Joan Macuszek

Masters Theses

Lycopodium flabelliforme (Fern.) Blanch. sporophytes were collected from a colony west of Flat Rock in Crawford County, Illinois. The material was either ground to a coarse grade using a Wiley Mill (grindate), left whole and untreated (fresh) or water extracted with a Waring blender (extract). The effect of the sporophyte material was tested on the germination of seeds and on the growth of seedlings of Raphnus sativa L. Sporophytes subjected to the grindate treatment showed the most inhibitory effects. It was shown that the alledged inhibitory substance was heat stable and able to be concentrated. Using column chromatography, at 37.7°C, …
