Inhibition Of Planarian Regeneration, Douglas Pierre Bingham

Theses and Dissertations

This thesis describes my study of inhibition of brain regeneration in planaria. The flatworm (Dugesia tigrina) possesses a remarkable ability to regenerate lost parts, including the head. The primary objective of my study was to determine the extent to which an inhibiting substance, located in the head, would prevent regeneration of the brain. A secondary objective was to study whether DMSO (Dimethyl Sulfoxide) would facilitate the action of the inhibitor.

Relationship Between Protein And Ribonucleic Acid Synthesis During Outgrowth Of Spores Of Bacillus Cereus, S. Rodenberg, W. Steinberg, J. Piper, Kenneth W. Nickerson, J. Vary, R. Epstein, H.O. Halvorson

Papers in Microbiology

The rate of protein and ribonucleic acid (RNA) synthesis was examined during the outgrowth of spores of Bacillus cereus T in a chemically defined medium. RNA synthesis started 2.5 min after the initiation of germination, and protein synthesis after 4 min. Addition of a complete amino acid supplement and uracil supported high rates of RNA and protein synthesis throughout outgrowth. To determine the relationship between the rate of protein (k) and RNA synthesis, the kinetics of formation of various classes of RNA were followed during outgrowth. Ribosomal RNA (rRNA) comprised a relatively constant fraction of the total RNA …

Some Phage Associated Properties In Salmonella Potsdam, Thomas B. Seifert

Loma Linda University Electronic Theses, Dissertations & Projects

The non-lysogenic strain and several lysogenic strains of S. potsdam were tested biochemically and antigenically to detect any possible phage related property.

Fermentation reactions and citrate utilization tests were identical for all strains.

Tubes agglutination tests showed the non-lysogenic and lysogenized strains of SP2-S to be similar, and different from the naturally lysogenic strains SP3, SP4, SP9, and SP10. Absorption tests confirmed the SP2-s strains, either non-lysogenic or lysogenized, to possess an additional antigen SP3 and SP4 did not possess. SP9 and SP10 may contain small amounts of this antigen. From variation may explain the antigenic difference between these strains. …

A protein with characteristics similar to actomyosin has been isolated from whole brain of rat and cat. It is soluble in 0.6 molar potassium chloride and insoluble in 0.1 1nolar potassium chloride. It superprecipitates with magnesium ions and adenosine triphosphate. It has adenosine triphosphatase activity stimulated by either 1nagnesium or calcium ions. Both superprecipitation and adenosine triphosphatase activity are inhibited by p-chloromercuribenzoate and Mersalyl but not by ouabain

The Biology Of Choristoneura Houstonana (Lepidoptera: Tortricidae), A Pest Of Juniperus Species, E. A. Heinrichs, Hugh E. Thompson

Department of Entomology: Faculty Publications

Choristoneura houstonana (Grote) lays eggs singly in July. Egg development ranged from 8 to 11 days, with the majority hatching 10 days after oviposition. Larvae are solitary, and mine during early instars, but later instars feed externally on leaves in shelters made by webbing foliage together. There is one generation each year, and overwintering occurs in a hibernaculum, in mined leaves. Field-collected head-capsule width frequencies indicated nine larval instars. Rearing larvae on seedling junipers indoors indicated a range of 8–11 instars. Pupation occurs during June and July in the shelter where the larva feeds. The pupal stage lasted about 10 …

Development Of A Mating System In Salmonella Potsdam, Anthony J. Zuccarelli

Loma Linda University Electronic Theses, Dissertations & Projects

A mutant of Salmonella potsdam SP2 which had been grown in mixed culture with either of three F⁺ strains of Escherichia coli was unable to serve as a donor of chromosomal genes when mixed with another mutant of S. potsdam. Therefore, there was no evidence of F transfer in these crosses.

To promote the formation of conjugal pairs, the filter mating technique of Matney and Achenbach was used. With this method, no recombinants were detected when six different Hfr strains of E. coli were mated with various mutants of SP2. Hfr K1 of Salmonella typhimurium transmitted loci for the …

Cultivation Of Trypanosoma Peromysci From Two Species Of Peromyscus, Norman R. Dollahon

Biology ETDs

Trypanosomes from mice of the species Peromyscus boylii and Peromyscus truei were isolated and cultured in NNN medium and in trypticase soy medium. A continuing culture of trypanosomes developed from blood of mice of the species P. truei. Trypanosomes from the blood of mice of the species P. boylii did not adapt to continuing cultures, but crithidias and rosettes were observed.

The cultures were incubated at temperatures of 1.5 C, 22 C, and 37 C. The organisms incubated at 1.5 C never advanced beyond the crithidial form, but they were observed in the culture medium after 40 days. The organisms …

The Effects Of Pre-Emergence Applications Of Simazine And Post-Emergence Applications Of Dalapon On Physio-Chemical Changes In Apple, Sour Cherry, Sweet Cherry, And Prunus Mahaleb, Jawad Thanoon Agha

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Simazine and dalapon have been used to control weeds in many crops during the last few years, but in 1963, when this study was begun, their uses in fruit orchards were limited. To study the effects of simazine and dalapon both on the control of weeds and on various metabolic changes in apple (Malis pumila), Montmorency sour cherry (Prunus cerasus), sweet cherry (Prunus avium), and Prunus mahaleb root stock, experiments were conducted from 1964 through 1966 in both the field and in the greenhouse.

The application of a low dosage of simazine (4 lb/A) to soil around twelve-year-old Montmorency sour …

The Secondary Benefits Of Irrigation Water: An Economic Appraisal, Erik Bruce Godfrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The secondary or external benefits of increasing the availability of water for irrigation and changing the allocation of an existing water supply was analyzed from a theoretical point of view.

"Input-output" models for Cache County, Utah, and for the state of Utah were used to indicate the intersectoral relationship of water used by agriculture and other sectors in each economy.

The indirect value of water used by agriculture in Cache County was estimated. A method that extended the procedure used in this thesis was proposed that could be used to estimate the value of water in ether sectors. A "water …

The Water Permeability Of Potato Tuber Tissue, Ward Bryce Roberson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments involving pressure, temperature, salt solutions, decenylsuccinic acid, a surfactant, and respiration inhibitors including azide, dinitrophenol, malonate, and iodoacetic acid were conducted to determine the extent to which the cytoplasm of the parenchymatous cells of the potato tuber influenced the tissue's water filterability.

The amount of water or solution moved through the potato tissue was measured by applying a pressure differential to the solution, forcing it across a 1.0 mm thick disc of tissue which was supported in a pressure filtration apparatus. The solution moved was collected and measured directly. In certain experiments the conductivity of dialysis membrane material was …

Some Aspects Of The Symbionts Of Cassiopeia Frondosa, Dolores Ahles O.S.F.

Journal of the Minnesota Academy of Science

Symbiodinium microadriaticum were found localized in the mesoglea of Cassiopeia, the upside-down jellyfish. Axenic cultures of the symbiont were produced, utilizing chemically defined media. Studies of the life cycle established the presence of isogametes which had previously been postulated. Reactions to various bands of the spectrum were noted, and tolerance tests for survival in darkness and under temperature stress were carried out. Nutritional experiments established nitrates as the best nitrogen source and verified the fact that vitamins B12 and Thiamine, though not essential far life, hove a stimulating effect on the growth and motility of these zooxanthellae.

Effect Of Substrate Types On Aquatic Insect Distribution, Henry L. Bell

Journal of the Minnesota Academy of Science

Effect Of Fluoroacetate On Amino Acid Metabolism / W. J. Nicklas, D. D. Clarke, And S. Berl. Chem. Dept., Fordham Univ., And Col. Of Physicians And Surgeons, Columbia Univ., New York, N. Y., William J. Nicklas, Donald Dudley Clarke Phd, Soll Berl

Chemistry Faculty Publications

Guinea pig brain cortex slices incubated in media containing U-14-aspartate or glutamate (GA) (J. Neurochem. in press) form glutamine ( GM) of relative specific activity (RSA)> 1 (GA=l). In the presence of 10-3 fluoroacetate (FA) the RSA of GM decreased to values considerably < 1 without any changes in levels of amjno acids; the % of label in GA doubled whilA that in GM decreased correspondingly. Similar results were obtained with 1-14 C-acetate as tracer in vivo (mice) and in vitro. RSA' s of Grvl > 1 have been explained by the compartmentation of GA in cerebral cortex. Consequently the effect of GA may be explained by an inhibition of the flow of metabolites through that pool of GA used preferentially for GM synthesis. This is consistent with the concept of the existence, in brain, of more than one citric acid cycle, one …

Chemistry Faculty Publications

(1) Compartmentation of glutamate metabolism in brain cortex previously observed only in vivo, has now been demonstrated in vitro. This was shown by using [U-14C]aspartate and [U-14C]glutamate as tracer substrates. (2) Preparation and maintenance of the slices at 0° resulted in reversible inhibition of glutamine synthesis. Preincubation at 37° for 10 min or preparation of the slices at room temperature partially overcame this inhibition. (3) Transfer to fresh medium after preincubation had an added stimulatory effect on glutamine synthesis. (4) Incubation in high K+ medium (27 mM) altered the relative specific activity of glutamine. (5) The data are in keeping …

The Sterile-Male Technique For Control Of Mosquitos: A Field Cage Study With Anopheles Quadrimaculatus, R. S. Patterson, C. S. Lofgren, M. D. Boston

Entomology Papers from Other Sources

The use of sterile males to control a cage population of a laboratory strain of Anopheles quadrimaculatus was not successful, even though 80 to 90% of the females laid sterile egg clutches. At the ratio of sterile males to normal males being used, complete sterility should have been quickly achieved. Subsequent studies of the survival and sexual vigor of these sterile males indicated that only a small number, about 5%, of the released males were actually competing with normal males for the uninseminated females. Thus, until a more hardy and sexually vigorous male A. quadrimaculatus can be reared in the …
