Parasites Of The Inshore Lizardfish, Synodus Foetens, From South Florida, Including A Description Of A New Genus Of Cestoda, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasites of the inshore lizardfish, Synodus foetens, were studied from collections taken from an estuarine canal in south Florida between January 1963 and December 1964. A new genus of Cestoda (Bothriocephalidae) has been erected with the proposed name Anantrum. Several larval and adult helminths and a dinoflagellate were studied from monthly samples of Synodus. Incidence of infection, intensity of infection, location of parasites in the host, and associations among parasites are discussed. Extensions of ranges for parasites in S. foetens and parasites heretofore not recorded from S. foetens are noted.

Synthetic And Complex Media For The Rapid Detection Of Fluorescence Of Phytopathogenic Pseudomonads: Effect Of The Carbon Source, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Fluorescence is of diagnostic value for differentiating among species of aerobic pseudomonads (R. Y. Stanier, N. J. Palleroni, and M. Doudoroff, J. Gen. Microbiol. 43:159, 1966). The standard medium for detecting fluorescence is Medium B (E. 0. King, M. K. Ward, and D. E. Raney, J. Lab. Clin. Med. 44:301, 1954), which supports fluorescent pigment production of most pseudomonads tested (0. Jessen, Pseudomonas aeruginosa and other green fluorescent pseudomonads, A taxonomic study, Munksgaard, Copenhagen, 1965; R. Y. Stanier et al., J. Gen. Microbiol. 43:159, 1966). Minerals (J. V.

Art In Psychotherapy, Robert R. Schopbach

Henry Ford Hospital Medical Journal

Art is a tool too often neglected in psychotherapy. A careful study of a patient's drawings will provide information concerning diagnosis, dynamics, and progress. If, in addition, the patient explains and elaborates upon the content and symbolism, the drawings become excellent psychotherapeutic devices providing an entry into the patient's unconscious.

Effect Of Temperature Upon Reproduction And Cyclic Development Of Culture Forms Of Trypanosoma Avium, Richard Michael Oliver

All Master's Theses

Though much research has been done on the parasitic protozoans of the suborder Trypanosomatina in general, particularly those pathogenic trypanosomes which infect mammals, relatively little research has been directed toward those forms which infect birds.

The Nitrogen Nutrition Of Emmonsia (Moniliales, Aleurismaceae), Gary L. Bradley

Loma Linda University Electronic Theses, Dissertations & Projects

The questions posed in this research concerned both the comparison of the nitrogen nutrition between Emmonsia parva and Emmonsia crescens and the comparative nitrogen utilization within the species. This fungus is a parasite with a rather uncomplicated life-cycle. Thus it lends itself well to study of the host-parasite relationship at the molecular level. This research contributes toward that long-range goal.

Five replicate floating cultures of each species were grown in 125 ml Erlenmeyer flasks containing a chemically defined basal medium plus one of the 29 nitrogen sources tested. Utilization of a particular source was determined by dry weight. The results …

The Effect Of Glucose On Neutrophilic Phagocytosis, Donald F. Adams

Loma Linda University Electronic Theses, Dissertations & Projects

Samples of blood were obtained from thirty healthy young adult males (Loma Linda University School of Dentistry), and contaminated with bacteria. Varying concentrations of pure glucose were added to this mixture to observe the effect of the glucose on in vitro neutrophilic phagocytosis. As the glucose levels increased a statistically significant suppression was noted in the ability of the neutrophilic leukocytes to engulf Staphylococcus epidermidis.

It was not possible, however, to predict the degree of suppression for any particular level of glucose added nor is it possible to state that suppression will occur in any one individual.

Two methods of …

Nutritional Relationship Between The Copepod Parasite Charopinus Dentatus (Wilson) (Lernaeopodidae) And The Skate Host, Raja Binoculata Girard, Donald W. Rigby

Loma Linda University Electronic Theses, Dissertations & Projects

Of 1,798 parasitic copepods, Charopinus dentatus (Wilson), collected from the skate host, Raja, binoculata Girard, 1,615 (89.87.) were obtained from the mucosa lining the mouth and pharynx. None were collected from the gill filaments. Host tissue damage was not seen grossly or microscopically around the attached parasite nor did the gut contents of female parasites give evidence microscopically or chemically that they are blood feeders. Green material from the gut of female parasites was made up of cell-like structures occurring singly and in clumps. Spectrophotometrically this material demonstrated spectral maxima (670, 410 'FM) similar to maxima of degradative products of …

Effects Of Dehydration Processes With Special Reference To Microwave Irradiation On Selected Biochemical And Physical Changes In Apples (Pyrus Malus), Fredoon Shahin Nury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many innovations have been attempted to shorten drying time or improve dehydration techniques for foods. Despite the recent advances in science and technology the bulk of dried fruit production throughout the world, over 1 1/2 billion tons (dry basis), is prepared by the energy of the sun (Copley and Van Arsdel, 1964). However, other techniques and processes for food dehydration and preservation are occupying more prominent positions in the overall production of dehydrated foods, particularly in the more advanced countries. Economics notwithstanding, it is readily apparent that dehydration as compared to sun-drying offers at least two main advantages. It is …

The Incidence And Life Cycle Of Eimeria Utahensis Sp. N. From Kangaroo Rats Of Northwestern Utah, John V. Ernst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A total of 176 kangaroo rats (151 Dipodomys ordii and 25 D. microps) were captured in northwestern Utah and examined for coccidia. Of these 176 rats, four D. ordii (2.6%) and four D. microps (16.0%) were infected with Eimeria utahensis, a new species of coccidia. Little seasonal difference was found in the infection rate of either species. The characteristics of the sporulated oocysts of this species were described. A sporocyst plug was reported for the first time in an eimerian oocyst.

Artificially excysted sporozoites were studied by various methods. Thirty living sporozoites averaged 22.5 𝜇 in length by …

A Study Of Factors Affecting The Germination Of Alfalfa And Safflower Pollen, Ling Lin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pollen grains serve a very important role in the life cycle of flowering plants, in that they are involved in the transmission of inherited characteristics from generation to generation. Because of their small size the study of pollen grains has been necessarily associated with the development of the microscope. Not until the middle of the seventeenth century, when Hooke gave the world the compound microscope, was an instrument available with sufficient power to adequately reveal the shapes of pollen grains. However, two of Hooke's contemporaries, Malpighi and Grew, who used a simple microscope, are generally recognized as the co-founders of …

Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.

With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

The Biosynthesis Of Aminolevulinic Acid In Relation To Iron And Enzyme, Daniel Ming-Yi Teng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The survey of plant species for aminolevalinic acid synthetase (ALAS) source was conducted. Under the conditions of this study, spinach leaves were found to be a good source of ALAS activity. The amount of amino levulinic acid (ALA) synthesized by the plant extracts was very small and was rapidly metabolized to porphyrins. ALA and porphyrin synthesis was found to be confined to the particulate fractions. Rupturing of the particles with ultrasonifier enhanced the penetration of succinyl-CoA and increased the activity. Direct study of the ALAS activity was enabled by the utilization of C¹⁴-compounds to the isolation by column …

Labeling Of Glutamate, Glutamine, And Aspartate In Brain From C14 Aspartate And Acetate / W. J. Ncklas D. D. Clarke And S. Berl Chemistry Dept., Fordham University And Col. Of Physicians And Surgeons, Columbia University, William J. Nicklas, Donald Dudley Clarke Phd, Soll Berl

Chemistry Faculty Publications

Guinea pig brain cortex slices incubated in media containing U-C14 aspartic acid form glutamine of higher specific activity than glutamic acid (Fed. Proc. -25, 713 (1966) ). Glutamic acid and glutamine from such experiments were enzymatically decarboxylated and the o/o of label in C-1 ranged from 37 to 42o/o. These values exceed the maximum predicted from the known operation of the citric acid cycle viz. 33o/o. When l-C14 acetate was injected into mice or incubated with brain slices the aspartate isolated from brain had more than 50o/o of the label in C-4. From the known operation of the citric acid …
