Significance Of Hemolytic Activity Of Some Radiation- Resistant Micrococci In Food, Ardyce Welch, R. Burt Maxcy

Department of Food Science and Technology: Faculty Publications

Micrococci resistant to 1 Mrad ofgamma radiation were isolated from irradiated chicken. Three isolates were hemolytic on blood agar plates and were selected for further study.Two other radiation-resistant micrococci, Micrococcus radiodurans and Micrococcus radiophilus, were included in the study because there is only a very limited amount of information regarding hemolytic activity of these organisms and their potential role of public health importance. Tests to determine hemolytic patterns, hemolytic activity of extracellular substances, leukocytic activity, presence of enzymes commonly associated with pathogenicity (coagulase, deoxyribonuclease, phosphatase), and pathogenicity for laboratory animals all suggested that the organisms would not be of …

Host Plant Preference In Two Generalist Herbivores, Jody Genelle Gray

Biology ETDs

The host plant preferences of two generalist lepidopteran herbivores were investigated at a field site near Albuquerque from 1977 to 1979. Observations of larvae in the field and measurements of available biomass for each host plant were combined to calculate preference rankings for host plants. Similarly, the relative preference of each herbivore for young or mature leaves was calculated. Both Estigmene acrea (Drury) and Hyles lineata (Fabricius) preferred to feed on Rumex hymenosepalus in the spring. H. lineata is univoltine and was not observed feeding on any other plant species. E. acrea is bivoltine and feeds on Senecio longilobus, Helianthus …

Steroid Hormones And Human Variability: Correlation Of Androgen Levels With Age And Occupation In Normal Subjects, Frances E. Purifoy

Anthropology ETDs

The endocrine system, coordinated with the central nervous system, is an important mediator of the genetic-environmental interactions which influence the development of human phenotypes. For this reason, endocrine parameters provide an important source of information for anthropological studies. This research focuses on the role of the endocrine system in normal human variability, with emphasis on the steroid hormones, which affect numerous aspects of mammalian morphology, physiology and behavior. Preceding the discussion of original research is an extensive literature review on hormonal variation in each of three areas: 1) sex and inter-individual variation, with emphasis on behavior; 2) variation with age, …

Small Mammal Population Dynamics And Community Structure In Three East Central Florida Communities, Mary Helen Keim

Retrospective Theses and Dissertations

Small mammal population dynamics and community structure were studied in three East Central Florida communities. The communities were compared as distinct stages of a sand pine scrub sere. The small mammals live-trapped with greatest frequency in this 3852 trap-night study were all cricetine rodents, Peromyscus polionotus niveiventris (beach mouse), Sigmodon hispidus littoralis (cotton rat), and Peromyscus gossypinus palmarius (cotton mouse). Population numbers, survival, body weights, hind foot lengths, age structure, sex ratios, reproductive cycles, and movements were discussed for each of three species mentioned. These data will serve as a baseline information for ecological monitoring studies associated with NASA Space …

(1975). This …

Inflorescence Architecture And Flower Sex Ratios In Sagittaria Brevirostra (Alismataceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

Two populations of Sagittaria brevirostra from the same lake were sampled 10 years apart and yielded similar data on inflorescence structure and on numbers and ratios of male and female flowers. Larger inflorescences have relatively more male than female flowers than do smaller inflorescences. Pollination success is unrelated to inflorescence size or sex ratio within an inflorescence.

A New And Unusual Eimerian (Protozoa: Eimeriidae) From The Liver Of The Gulf Killifish, Fundulus Grandis, Donald W. Duszynski, Mobashir A. Solangi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oocysts and sporocysts of Eimeria funduli sp. n. are described from the Gulf killifish, Fundulus grandis, on the basis of light microscopy, transmission and scanning electron microscopy, and location in the liver of infected hosts. The spherical sporulated oocysts of E. funduli isolated from liver tissue measure 20-31(25) μm across with ovoid sporocysts 9-11 × 5-7 (10 × 6) μm. A micropyle, polar granule, and oocyst residuum are absent, but sporocysts have Stieda and substieda bodies, a few residual granules, and 10-25 (15) unique projecting structures with expanded distal portions that we term “sporopodia.” Sporopodia 1-3 (2) μm high …

The Development Of Techniques For The Enumeration Of Selected Pathogenic Bacteria In Lynnhaven Estuarine Sediments, Mark T. Frank

Biological Sciences Theses & Dissertations

Methodologies for the improved recovery of selected pathogenic bacteria from estuarine sediments were investigated. Laboratory and field studies were conducted to document the sensitivity of the techniques for isolating Salmonella species, Pseudomonas aeruginosa, and Vibrio parahaemolyticus. Vibrio parahaemolyticus-like organisms were enriched in a seawater yeast extract broth and isolated from Thiosulfate Citrate Bile Salts Sucrose plated media. Enrichment procedures with and without elevated temperatures and subsequent transfers to selective and differential plated media have been examined for the isolation of Salmonella species and P. aeruginosa. These pathogens were initially assayed for utilizing primary enrichments of asparagine …

The Synthesis And Evaluation Of The Potential Antineoplastic Activity Of The Semicarbazone And The Thiosemicarbazone Derivatives Of The Di-2-Pyridyl Ketone And The 1,8-Diazafluorenone Ring Systems, Adriene Y. Principe

Chemistry & Biochemistry Theses & Dissertations

A number of' a-(N)-heterocyclic thiosemicarbazones have been synthesized and evaluated for potential antineoplastic activity since Brockman and colleagues2 reported the antineoplastic activity of' 2-f'ormylpyridine thiosemicarbazone (1). The primary objective of' this research project has been the synthesis and characterization of' the semicarbazone and the thiosemicarbazone derivatives of' the di-2-pyridyl ketone, (9-a) and (9-b), and the 1,8-diazaf'luorenone, (10-a) and (10-b), ring systems, as well as the evaluation of' these compounds for both in vitro and in vivo antineoplastic activity against Ehrlich ascites tumor cells in mice. These studies have suggested that di-2-pyridyl ketone thiosemicarbazone (9-b) is as effective as 2-formylpyridine …

Structure Of A Subtidal Benthic Community Near Cape Charles, Virginia, R. Michael Ewing

Biological Sciences Theses & Dissertations

Species composition, distribution, and abundance of benthic invertebrates of a subtidal community were examined at a location on the lower Delmarva Peninsula near Cape Charles, Virginia. Macrobenthos was sampled quarterly between June, 1977 and June, 1978 at nine sites along a transect in Old Plantation Creek and the adjacent offshore area. Spatial and temporal patterns of numerically important species are discussed.

Sampling sites and species were grouped by a numerical classification strategy which consisted of the Bray-Curtis similarity measure and group-average clustering. Three faunal assemblages were identified with the aid of constancy and fidelity nodal analyses: (1) a tidal creek …

A Method For Evaluating The Platelet Surface Response By Using Electron Microscopy, Jeanne M. Riddle

Henry Ford Hospital Medical Journal

Our method for evaluating the surface response of any given platelet population, which has evolved over the past two decades, provides a measure of both the adhesive and cohesive qualities of platelets. General morphologic features of the adherent, whole platelets can be assessed by transmission electron microscopy, and the results are reproducible when serial samples are collected on normal subjects and patient groups. With this technique, different metabolites and drugs can be combined with platelet populations that are either normoresponsive or hyperactive to determine if these substances trigger or inhibit the platelet response. To date, the results from in vitro …

Functions And Interrelationships Of Leukocytes In Inflammation As Elucidated By The Rebuck Skin Window Technique, Sheikh M. Saeed

Henry Ford Hospital Medical Journal

This article provides an overview of the functions of human leukocytes in inflammation as elucidated by the Rebuck skin window technique. The migration sequence of various leukocytes into the field of inflammation is described, as well as cytologic, cytochemical, and transformational changes, and the interrelationships of responding leukocytes. Since it was introduced in 1955, the Rebuck skin window technique has provided an excellent means of studying in vivo inflammatory response to different phlogistic agents in normal individuals and in various disease states. This simple technique continues to prove fruitful to further study and to monitoring of many disease states.

Igg Lymphoplasmacytic Intestinal Lymphoma: A Case Report, Heidrun Z. Rotterdam, Sheldon C. Sommers

Henry Ford Hospital Medical Journal

We describe a rare case of a localized primary small intestinal lymphoma with features of both the Mediterranean and the Western type. This case demonstrates the need to regard intestinal lymphoma as a spectrum of diseases with the Mediterranean and the Western types at opposite ends and many variants in between. The role of the plasma cell infiltrate has been interpreted as reactive as well as neoplastic. In our case, both lymphocytic and plasmacytic proliferations spread widely in the intestinal submucosa, extended into muscularis propria and subserosal fat, and involved mesenteric lymph nodes. Direct immunofluorescence demonstrated IgG-kappa both in plasma …

The Role Of High Molecular Weight Kininogen (Fitzgerald Factor) In The Activation Of Various Plasma Proteolytic Enzyme Systems, R. Waldmann, A. G. Scicli, J. Guimaraes, G. Scicli, Oscar A. Carretero, H. Kato, Y. N. Han, S. Iwanaga

Henry Ford Hospital Medical Journal

Bovine high molecular weight kininogen (bHMWK) partially corrects the aPTT of Fitzgerald-trait plasma, which is congenitally deficient in HMWK. The relationship between the structure and activity of HMWK was clarified by studying the effects of different fragments of bHMWK on the aPTT of Fitzgerald-trait plasma. The peptides studied, all in equimolar concentrations, were lys-bradykinin-free HMWK, bradyk In In-fragment 1-2-tree HMWK, heavy chain, fragment 1 -2-Hght chain, and light chain. Bradykinin- fragment 1-2-free HMWK, heavy chain, and light chain have little or no correcting activity upon Eitzgeraldtrait plasma aPTT. Fragment 1-2 light chain has the same correcting activity as intact bHMWK, …
