Antibiocity of the Oleoresins of One Hundred Texas Spermatophytes upon Twenty Gram-Positive Bacterial Organisms

Antibiocity of the Oleoresins of One Hundred Texas Spermatophytes upon Twenty Gram-Positive Bacterial Organisms

Date: 1949
Creator: Richardson, Lavon P.
Description: This investigation is concerned with the testing, in vitro, of oleoresins from one hundred higher plants common to North and South Central Texas. The plants used were selected in order to obtain a representative collection which might be of value in future research.

The Antibiotic Activities of Some Members of the Cactaceae Family

The Antibiotic Activities of Some Members of the Cactaceae Family

Date: 1951
Creator: Gilmore, Derward E.
Description: This problem has been concerned with, first, the collection of sixteen species of plants belonging to Cactaceae family; second, the drying of these and the extraction of the oleoresins thereof; third, the determination of the extent to which these substances inhibit the growth of ten gram-positive and ten gram-negative bacterial organisms; and fourth, a determination of the possible utilization of these extracts a prophylactic or chemotherapeutic agents.

The Antibiotic Effect of Pigmented Actinomycetes

The Antibiotic Effect of Pigmented Actinomycetes

Date: 1951
Creator: Cichon, Casimir Joseph
Description: This thesis attempts, first, to correlate pigmentation of actinomycetes with the degree of antibiocity; second, to establish the most favorable means of producing a rich luxuriant pigmentation in the individual organism studied by enriching favorable media with specific types of proteins and amino acids.

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

The Antibiotic Properties of the Oleoresins of Twenty-Five Common Garden Vegetables

Date: 1951
Creator: Ennis, Arthur F.
Description: The purpose of this problem is to determine the presence and extent of antibiotic materials as found in the oleoresins of a selected group of garden vegetables. The problem has consisted of, first, the collection and preparation of specimens of twenty-five commonly used garden vegetables; second, the extraction of the oleoresins from these; third, the determination of the inhibitory and other effects of these oleoresins against several strains of selected gram-positive and gram-negative bacteria; and fourth, the evaluation of the potentialities of these oleoresins with regard to their future use as medicinal prophylactics and therapeutics.

Application of cultured neuronal networks for use as biological sensors in water toxicology and lipid signaling.

Application of cultured neuronal networks for use as biological sensors in water toxicology and lipid signaling.

Access: Use of this item is restricted to the UNT Community.
Date: August 2004
Creator: Dian, Emese Emöke
Description: This dissertation research explored the capabilities of neuronal networks grown on substrate integrated microelectrode arrays in vitro to be applied to toxicological research and lipid signaling. Chapter 1 details the effects of chlorine on neuronal network spontaneous electrical activity and pharmacological sensitivity. This study demonstrates that neuronal networks can maintain baseline spontaneous activity, and respond normally to pharmacological manipulations in the present of three times the chlorine present in drinking water. The findings suggest that neuronal networks may be used as biological sensors to monitor the quality of water and the presence of novel toxicants that cannot be detected by conventional sensors. Chapter 2 details the neuromodulatory effects of N-acylethanolamides (NAEs) on the spontaneous electrical activity of neuronal networks. NAEs are a group of lipids that can mimic the effects of marijuana and can be derived from a variety of plant sources including soy lecithin. The most prominent NAEs in soy lecithin, palmitoylethanolamide (PEA) and linoleoylethanolamide (LEA), were tested individually and were found to significantly inhibit neuronal spiking and bursting activity. These effects were potentiated by a mixture of NAEs as found in a HPLC enriched fraction from soy lecithin. Cannabinoid receptor-1 (CB1-R) antagonists and other cannabinoid pathway modulators indicated ...

Application of Fluorescent Antibody Methods for the Enumeration and Identification of Bacilus Cereus

Application of Fluorescent Antibody Methods for the Enumeration and Identification of Bacilus Cereus

Date: August 1969
Creator: Ferebee, Robert Newton
Description: This particular work is proposed as a test of the expedience of using the fluorescent-antibody technique as a method for enumeration and identification of certain strains of B. cereus that have been found to be effective in preventing taste and odor in water supplies resulting from certain Actinomycete blooms.

Applications of remote sensing and GIS to modeling fire for vegetative restoration in Northern Arizona

Applications of remote sensing and GIS to modeling fire for vegetative restoration in Northern Arizona

Date: August 2003
Creator: Hardison, Tanya
Description: An accurate fire model is a useful tool in predicting the behavior of a prescribed fire. Simulation of fire requires an extensive amount of data and can be accomplished best using GIS applications. This paper demonstrates integrative procedures of using of ArcGIS™, ERDAS Imagine™, GPS, and FARSITE© to predict prescribed fire behavior on the Kaibab-Paiute Reservation. ArcGIS was used to create a database incorporating all variables into a common spatial reference system and format for the FARSITE model. ArcGIS Spatial Analyst was then used to select optimal burn sites for simulation. Our predictions will be implemented in future interagency efforts towards vegetative restoration on the reservation.
