1982 Annual Report

Southeast Research and Extension Center: Reports and Administration

1982 was a year of challenges for all the various members of our unit including the researcher, the extension worker, the forester, and all the support staff. Our program year started on October 1, 1981 and ended on September 30, 1982.

From the agriculture standpoint, it has been a difficult year. The fall of 1981 was not favorable to the agricultural producer. Rain, freezing temperatures and even light snow was prevalent in October, 1981. Throughout the winter of 91-82, it was cold and snow was on the ground most of the winter.

It was not uncommon for counties in the …

Use Of Dry Whey And Lactose Hydrolysis In Yogurt Bases, Nagendra P. Shah

Electronic Theses and Dissertations

Yogurt is one of the oldest and most traditional fermented dairy products. Since early times it has been an important food item of the people in the Middle East. Except for its refreshing taste and wholesomeness as a food, no special virtues were claimed for it until early in the 20th century when the bacteriologist, Elie Metchnikoff, who shared a Nobel Prize in 1908, concluded from his studies on the effect of lactic acid bacteria of the digestive tract, that yogurt arrests putrefaction in the intestinal tract and thus might be beneficial to health (55). Attempts to popularize yogurt in …

Effects Of Various Hormones On Human Carcinoma Cell Proliferation, Y. L. Gao, B. S. Leung, A. H. Potter, W.C.Y. Yu

Journal of the Minnesota Academy of Science

Cell proliferation of a mammary adenocarcinoma cell line, CAMA-1. is affected by a number of steroid hormones and prolactin in long-term cultures. Estrogenic compounds stimulate cell growth while antiestrogenic compounds inhibit it. Prolactin can synergize the estrogenic effect. Progesterone, glucocorticoid or androgen reduce cell proliferation. Dihydrotestosterone is a very potent inhibitor,- effective at as low as 10 nM, and its effect is independent of estrogen action. Cortisol is a less effective inhibitor at concentrations below 10 nM; at these levels cortisol exhibits a slight inhibition which appears to be unrelated to estrogenic action. However, at higher concentrations, cortisol markedly reduces …

The Plant Pathogenic Corynebacteria, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

The plant pathogenic corynebacteria are a fascinating group of bacteria that produce effects as diverse as any in the microbial world, ranging from wilts to abnormal growths. Several new pathogens have been discovered since this group was reviewed by Jensen (75), Starr (157), and Lelliott (96). Most subsequent reviews have dealt with taxonomy. The areas covered in this review necessarily reflect my biases and limitations. However, this review attempts to be comprehensive in some areas, and it calls attention to other areas that would benefit from more detailed investigation.

Hormonal Interrelationships Between Hypothalamus, Pituitary And Testis Of Rams And Bulls, Bruce D. Schanbacher

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This mini-review aims to summarize some of our recent findings relating to testicular function and feedback control of the hypothalamic-pituitary axis by testicular steroids in rams and bulls. Testosterone secretion in intact males is not tonic, but is characterized by episodic pulses. This pattern of secretion is dictated by inputs of the central nervous system via secretions of the hypothalamus (luteinizing hormone- releasing hormone; LHRH) and anterior pituitary (luteinizing hormone; LH). A temporal relationship exists between concentrations of LH and testosterone in serum and evidence is presented that strongly suggests that their episodic secretion is dependent on discrete episodes of …

A Cytomorphological Study Of Podospora Curvicolla (Winter) Niessl, Stephen F. Tomasino

Masters Theses

A cytomorphological study was performed on Podospora curvicolla, a saprophytic Pyrenomycete. Major emphasis was placed on three important features: (I) ascocarp formation and development, (II) centrum structure and (III) ascus development and structure. A comparison with other studies of Podospora and with a genus generally considered closely related, Sordaria, was made to this present study of P. curvicolla.

Initial perithecial formation in P. curvicolla is indicated by a spherical mass of hyphae which may include filaments from many vegetative hyphae, but no apparent ascogonia or antheridia were observed. As the young perithecium matures in P. curvicolla, …

The Influence Of Salinity On Larval Development And Population Dynamics Of Anopheles Merus Dönitz (Diptera: Culicidae), F. W. Mosha, C. M. Mutero

All Peer-Reviewed Publications

Variations in density of adults of Anopheles merus Dön. in Jimbo Village on the Kenya Coast were found to be correlated both with rainfall and with salinity at their breeding sites. Densities started to increase at the beginning of the rains when several breeding sites were formed. This was followed by a decline in numbers resulting mainly from the decrease in salinity in the semi-permanent breeding sites. A second rise occurred after the end of the rains, corresponding with an increase in salinity in the semi-permanent breeding sites due to evaporation. Peak density coincided with salinities of 30–50% sea water …

Studies On Coagulase-Negative Staphylococci, Linda Flato Knowles

University of the Pacific Theses and Dissertations

The recent realization that coagulase-negative staphylococci are of medical importance led to a number of studies which attempt to characterize them more adequately. These studies have shown that the coagulase-negative staphylococci represent a “complex” of several species. Kloos and Schleifer, who are credited with the major effort to characterize the group, list (1975b) nine species: S. epidermidis, S. saprophyticus, S. capitis, S. cohnii, S. haemolyticus, S. hominis, S. simulans, S. wylosus, and S. warneri. Hajek (1976) added a new one, S. intermedius, isolated from animals; Kloos et al. (1976b) described S. sciuri, and Deviese et al. (1978) transferred Micrococcus hyicus …

Experimental Induction Of Resistance To An Acylurea Insect Growth Regulator, Mary Elizabeth Codrea

University of the Pacific Theses and Dissertations

A laboratory colony of a multi-insecticide susceptible strain of the housefly, Musca domestica was challenged with continuous larval selection pressure equivalent to the initial LC 60 level for 8 generations with the insect growth regulator WL 86303 (1-(3,5-dichloro-4)4-nitrophenoxy- phenyl)-3 -(2)chlorobenzoyl)- urea). A more than twofold increase in resistance was observed at the F8 generation. No cross-tolerance to the related compound, diflubenzuron (DIMILIN ^(R)) (1-(4-chlorophenyl)-3- (2,6-difluorobenzoyl)-urea) was observed after 8 generations. WL 86303 was significantly less toxic to houseflies than diflubenzuron. No significant difference was noted between the toxicity of WL 86303 to an unpressured wild housefly strain, and to …

Standardization Of The Sister Chromatid Exchange Technique In Human Lumphocytes For Mutagen And Carcinogen Testing, Kamlesh Sharma

Dissertations

The differential staining of chromosomes with the use of 5-bromo-2'-deoxyuridine (BUdR) was discovered in 1972. Since then, the BUdR technique has been modified and improved. It is used to study cellular kinetics; yet its most extensive use today is focused on studying sister chromatid exchange (SCE). Studies show that the frequency of SCEs increases significantly in the presence of mutagenic and carcinogenic agents. Hence, the BUdR technique (commonly referred to as the SCE technique) has been useful as a diagnostic tool to test for mutagenic anc carcinogenic agents.

Investigators have used differential staining to obtain a baseline incidence of SCEs …

The Microbial Biochemical Potential Of Two Detention-Retention Marshes In The Kissimmee River Valley Watershed, Douglas A. Winkelmann

Retrospective Theses and Dissertations

One of the major programs to abate the deterioration of water quality in the Lake Okeechobee watershed was the addition of detention-retention facilities. The microbial biochemical potential of two different detention-retention marshes in the Kissimmee River Valley were examined to determine their effectiveness to improve water quality. The kinetics of decomposition and nutrient mineralization and assimilation, as mediated by microorganisms, and the enumeration of microorganisms capable of utilizing various substrates were studied. Various communities within each marsh were studied during a 2-year period. The decomposition rates of 3 plant substrates were determined. Chitin was used as a standard for organic …

A Quantitative Description Of Migratory Behavior Of The Brown Shrimp (Penaeus Aztecus) With Applications In Fisheries Management, Anne Madolyn Babcock

OES Theses and Dissertations

A quantitative description of the migratory behavior of the brown shrimp, Penaeus aztecus, was established using the density approach. A theoretical time density was estimated by the proportion of catch and catch per boat hour NOAA-NMFS fisheries statistics collected in Pamlico Sound, the Neuse River, and Core Sound. A clear quantitative description of brown shrimp migratory timing is found in the time densities. The impact of various physical tactors on the progress of the fishery in time and space can be objectively evaluated by using the time density statistics as dependent variables in modeling efforts. The distributions also enable …

The Effects Of Copper On Skeletonema Costatum (Greville) Cleve, Susanne Sybille Jackman

Biological Sciences Theses & Dissertations

Copper levels and dominant phytoplankton species composition were examined from six sites in Kings Creek on Virginia's Eastern Shore from March to August 1980. Creek copper levels were determined by an APDCMIBK extraction procedure and ranged from 0.003 to 0.020 mg/1. Diatoms were the dominant phytoplankters with Skeletonema costatum (Greville) Cleve emerging as a major late summer species.

Subsequent laboratory studies involved 96-hour experiments using Skeletonema costatum (clone Skel) grown in enriched natural seawater. The water was collected from Kings Creek and enriched to Guillard and Ryther's (1962) f/2 media levels. Cupric sulfate was added to the experimental culture media …

Selection And Characterization Of Cole1 Plasmid Mutants That Exhibit Altered Stability And Replication., Joseph Inselburg

Dartmouth Scholarship

This report describes a method for isolating mutants of plasmid ColE1 that exhibit unstable maintenance and altered replication characteristics. It also describes the initial characterization of four mutants isolated by that method. A chimeric plasmid, pHSG124, containing a ColE1 derivative and a temperature-sensitive replication derivative of pSC101 was mutagenized in vitro, using hydroxylamine. By adjusting the growth conditions of transformants containing the mutagenized chimeric deoxyribonucleic acid, it was possible to rapidly screen colonies and identify those that had a high probability of carrying ColE1 mutants that exhibit unstable maintenance. Of those mutants, some exhibited altered copy number or accumulated catenated …

The Effects Of Levamisole, Corynebacterium Parvum, And Unblocked Lymphocytes On Mice Injected With Herpes Virus Type 2-Transformed Cells, Linda Martin Kelln

Loma Linda University Electronic Theses, Dissertations & Projects

The association between herpes simplex virus type-2 and carcinoma of the cervix is becoming increasingly strong (Rawls, et al., 1976 ; Rapp and Duff, 1974; Hollingshead, et al-, 1973). This study demonstrates the ability of certain known immunostimulators to beneficially· alter the immune status of mice injected with HSV-2 transformed cells.

Balb/c mice were randomly divided into 6 groups. Group 1 mice were used as negative controls and received no tumor cell injection. All other groups received subcutaneous injections of 1 x 10⁶ cells/ mouse. Tumor therapy by means of irrmunostimulation was started for each group of mice 1 …

The Effects Of Orthodontic Repositioning Into A Surgically Expanded Site On Bone Formation And Tooth Mobility In A Baboon, Anthony B. Lier

Loma Linda University Electronic Theses, Dissertations & Projects

For sometime, expansion of the maxillary arch, by means of surgical and mechanical procedures, have been acknowledged with minimal attention directed toward the mandible. In this pilot study a surgical technique was employed in separating the mandible, A-P, at the symphysis. The interosseous void, approximately 10 mm., was then filled with autogenous bone marrow collected from the greater trochanter and the crest of the ilium.

The surgical site was then maintained for a period of eight (8) weeks with the aid of a precast chromium-cobalt splint and titanium mesh placed intradentally and at the symphysis, respectively. Following the stabilization period …

Electrophoretic Mobilities Of Topoisomers Of Φx174 Dna, Virginia Mckee Hanson

Loma Linda University Electronic Theses, Dissertations & Projects

The analysis of nucleic acid structure by zone electrophoresis in agarose gels has become an increasingly important method in studies requiring the separation and identification of species differing only slightly in molecular weight or conformation. We have demonstrated the existence of several circular DNA forms that appear in cells infected with the bacteriophage ΦX174.

Wt/am3 heteroduplex molecules containing a single base mismatch (relaxed RFI molecules) were constructed in vitro, purified by sedimentation, and analyzed by zone electrophoresis on 1.4% agarose gels. In order to verify that the band of denaturation-resistant heteroduplex was indeed relaxed RFI, we compared …

Inhibition Of In Vitro Macrophage Digestion Capacity By Infection With Leishmania Donovani (Protozoa: Kinetoplastida), Gerald F. Kutish, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Promastigotes of Leishmania donovani transformed into amastigotes and survived in cultured macrophages. Promastigotes of Leptomonas costoris, a kinetoplastid parasite of water striders, transformed into amastigotes but did not survive in cultured macrophages. A significant difference in size between the two species of parasitic protozoa allowed development of a bioassay in which the in vitro digestion rate of L. costoris was taken as a measure of macrophage digestive capacity following preinfection with L. donovani. In a 12- to 24-hr period, macrophage cultures infected with the 2S strain of L. donovani retained 50% more L. costoris than did control macrophages …

In Vitro Enzymatic Assay Of Rna Methylation, Pamela Jean Eubanks Gallup

Chemistry & Biochemistry Theses & Dissertations

An assay procedure for in vitro enzymatic methylation of mannnalian ribosomal RNA has been developed in this study. The assay procedure, utilized for the comparison of normal and neoplastic methylase activities (using mouse liver and Ehrlich ascites cells as sources of enzyme), is a modification of previously published methods (52,53). A 100,000 x g supernatant (SlOO) enzyme preparation was incubated with 28S-5.8S rRNA and tritium-labeled S-adenosyl-L-methionine. The RNA was extracted, applied to DEAE cellulose paper, washed, and the radioactivity counted. The neoplastic cell methylase preparation was more active in methylating both exogenous neoplastic and normal 28S-5.8S rRNA than the normal …

Petroleum-Utilizing Bacteria: The Biological Line Defense Against Oil Pollution, Steven W. Sokolowski

Biological Sciences Theses & Dissertations

A silica gel-petroleum (SGP) medium was developed which is reliable, approximately the same cost as that of the corresponding agar-based petroleum medium, and can be made sufficiently firm to use in streaking or the spread-plate technique. Advantages of the medium include: the incorporation of all of the major ions of seawater in accordance with Dittmar's Law (the salinity of which can easily be varied from 0 to 35 parts per thousand); a wide workable pH range (5.5 to 11.6); negligable pH drift(~ 0.2 pH units after 166 days); the elimination of all but negligable amounts of syneresis, the ability to …

Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis

Biological Sciences Theses & Dissertations

Duck plague virus causes a hemorrhagic disease affecting the family Anatidae, resulting in 60-80% mortality in captive flocks. Plaque and neutralization assays for Anatid herpesvirus (AHV) require 5-10 days for completion and are restricted by the seasonal availability of fertile duck eggs. The enzyme linked innnunosorbent assay (ELISA) is rapid and specific and avoids the use of living cells. The Holland strain of AHV was grown on duck embryo fibroblasts and purified by banding on CsCl gradients. The resulting virus was used to raise antisera in prebled New Zealand white male rabbits. Antibody production was confirmed in double diffusion plates …
