Stress Urinary Incontinence In The Human Female: Gravity And Ecomorphologic Influences On Bladder And Urethral Function Of The Human Female, C. Paul Hodgkinson

Henry Ford Hospital Medical Journal

This study was undertaken to determine if the biped stale of the human female constituted a stress force in urethrovesical physiological function. To arrive at realistic conclusions, the ecomorphologic changes incidental to the conquest of gravity by the vertebrates have been reviewed. Accepting the evolutionary precepts as expressed by Hobart Smith that "if all parts of the evolutionary chain were known, it would be impossible to draw a logical distinction between man and nonman, Romer slated "Bone for bone, muscle for muscle, organ for organ, almost every feature of the ape is repeated in the human body. The differences are …

Aqueous Microbiology: The Possible Role Of Cell Wall Deficient Bacteria In Uveitis, Philip C. Hessburg, Lioa H. Mattman, Carolyn Barth, Lloyd T. Dutcheshen

Henry Ford Hospital Medical Journal

Samples of aqueous humor were obtained from the anterior chamber of patients with uveitis. Bacterial L-forms, or cell wall deficient forms, were recovered from 11 of 19 eyes with unexplained uveitis. These bacterial variants were cultured on newer, highly specialized media and stained with acridine orange. This stain demonstrates fluorescence of nucleic acids under UV microscopy.

Characterization Of Xanthomonas Phaseoli Bacteriophages, Anne K. Vidaver, Max L. Schuster

Department of Plant Pathology: Faculty Publications

Ten bacteriophages for Xanthomonas phaseoli were characterized. On the basis of adsorption rates, latent period and burst size, plaque morphology, host range, efficiency of plating, ultrastructure, sensitivity to osmotic shock, streptomycin sensitivity, temperature effects on plating efficiency, and serology, the phages were separated into at least three groups. Some of the phages were infectious for Pseudomonas phaseolicola (four strains) and P. syringae (one strain) in a narrow temperature range. The taxonomic and ecological significance of this finding is discussed.

Morphology And Development Of The Flowers Of Boottia Cordata, Ottelia Alismoides, And Their Synthetic Hybrid (Hydrocharitaceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

The inferior ovary of Boottia cordata, Ottelia alismoides, and their hybrid is appendicular in nature, the carpels are congenitally only slightly connate, and they are unsealed. All floral organs except the sepals originate from common primordia in the female and bisexual flowers. A flat residual floral apex is present. There is a vestigial superior ovary of three ontogeneticallv fused carpels in the male flower of Boottia cordata. The hybrid is intermediate in many characteristics and has partially fertile stamens and staminodia. The sequence of development in all flowers is acropetal. These plants appear to be related to …

Variation Within Herds Under Different Housing Systems, G. R. Wiggans, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

New York Holstein herds (1,152) including 75,875 cows were classified by housing system (stanchions, free stalls, and other combinations). Records initiated in these herds from 1964 to 1968 were used to determine the degree to which housing type might affect variance of milk production records in herds with 45 or more cows.

The within-herd variances by lactation for each housing system in each year-season were examined by Bartlett's test for nonhomogeneity among housing systems. Records in the stanchion systems were less variable than those in free-stall systems. This difference was not large enough to require adjustment for type of housing …

Discrimination Reversal Learning As An Index Of Memory In Spermophilus Tridecemlineatus, Waneta Kay Coester

Biology ETDs

Spermophilus tridecemlineatus were trained to solve a simple visual discrimination problem. Following a 15-day non-training period the ground squirrels were trained on-a series of five discrimination reversal problems. Criterion and non-correction procedures were followed during original and reversal training. During the non-training period one half of the subjects (Group I) remained in the training laboratory and the remainder of the animals (Group II) hibernated.

It was possible to train the animals to solve the original discrimination and the reversal problems. No statistically significant differences were observed between performances on consecutive problems. However, differences approaching statistical significance were observed between performances …

The Effect Of Two Growth Retardant Chemicals, Cycocel And B-Nine, On Certain Nitrogeneous Components In Barley Seedlings, Linda Kinser

Masters Theses & Specialist Projects

Certain chemicals are known to inhibit growth in many plant species. These chemicals possess a common trait, the ability to inhibit stem elongation by suppressing the activity of the subapical meristematic region (11). These growth retardants have been extensively studied during the past several years in an effort to determine the biochemical mechanism responsible for reduction in plant height. The characteristic effect of these chemical retardants on the growth pattern has been described as producing plants with shorter, thicker stems and broader, darker green leaves. Tolbert, however, noted that although plants treated with the plant growth retardant, Cycocel, (2-chloroethyltrimethlammoniumchloride) and …

An Investigation Of A Mycorrhizal Association On Opuntia Polyacantha, R. Craig Stutz

Theses and Dissertations

Roots of Opuntia, polyacantha Haw. from Juab County, Utah were found to be nodulated. An anatomical study of the nodulated roots showed them to be ectotrophic mycorrhizae. Fusarium poae (Peck) Wollenweaver was found associated with the nodules both as an epiphyte and an endophyte. However, reinfection with this organism failed to induce subsequent nodulation. Under certain conditions the roots of o. polyacantha are able to overcome the mycorrhizal infection and elongate. It is not uncommon for several branch roots to originate from a single nodule. It is suggested that the fungus-root association found in o. polyacantha represents an early stage …

The Effect Of Photoperiod On The Diurnal Fluctuations In Photosynthetic Rate Of Two Species Of Marine Phytoplankton, Richard Allmon Smith

Master's Theses

Photosynthetic rates were measured under constant conditions over a 24 hour period for cultures of Skeletonema costatum and Amphidinium carterae grown under various light - dark regimes. Photosynthetic rate fluctuated for both species under all photoperiods except for A. carterase under 8 hours light per day. Maximum photosynthetic rates occurred generally in the middle of the. light period and minimum rates.in the middle of the dark period. The ratio of maximum to minimum rates, or Pmax/min, differed significantly under the various photoperiods. Pmax/min values . for A. carterae were significantly greater than for s. costatum. The greatest Pmax/min for S …

Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley

Masters Theses

The short-term growth response of etiolated pea stem segments (Pisum sativum L., var. Alaska) was investigated using a high-resolution growth recording device. The immediate effect of treatment with indoleacetic acid (IAA) is an inhibition of growth. This inhibition lasts about 10 minutes and then the rate of elongation rises abruptly to a new steady rate about 4 times the rate of elongation before auxin treatment. This rapid steady rate of elongation, however, continues for only about 22 minutes before declining suddenly to a lower steady rate of growth about 2 times the rate of elongation before the addition of auxin. …

A Biological Investigation On Plethodon Larselli, Charles Oliver Holmes

All Master's Theses

The purpose of this study is to increase the presently-lacking biological knowledge of P. larselli. A study was made, therefore, on this species relative to its geographical distribution, habitat, dehydration and rehydration rates, response to induction with varying concentrations of a gonadotropic hormone, and blood serum analysis by cellulose acetate electrophoresis. In addition, the findings of this investigation will help elucidate the relationship between P. larselli and P. vehiculum.

Food Habits Of Dicamptodon Ensatus And Associated Fish Species Of Maratta Creek, Washington, Authur L. Antonelli

All Master's Theses

Three cold-blooded vertebrates, Dicamptodon ensatus, Cottus tenuis, and Salmo gairdneri were investigated as to food habits for a period of one year. The existence of competition between these animals for food was determined by means of stomach analysis. The results were compared relative to each vertebrate and the bottom fauna procurred from the stream. It was shown that the food habits of D. ensatus and S. gairdneri were diverse enough to warrant partial exclusion on the basis of food. C. tenuis demonstrated selectivity and was shown to be under competitive stress from the other two species.

Ultrastructural Investigations Of Tilletia Caries Teliospores, James Vincent Allen

Theses and Dissertations

The purpose of this study was to investigate the ultrastructure of Tilletia caries teliospores. Specimens were prepared for viewing in the electron microscope by freeze-etching and thin-sectioning techniques. Thin-sectioning techniques gave excellent results with the teliospore walls and the lipid bodies within the teliospore but failed to adequately fix the membranes and internal organelle systems. Micrographs of Tilletia caries teliospores prepared using thin-sectioning show three major wall layers and two partition wall layers and abundant lipid bodies. The freeze-etch method of spore preparation proved superior to the thin-sectioning used in this study to reveal the internal organelle systems of the …

Surface Characteristics Of Conidia From Monosporous Cultures Of Penicillium Digitatum And Aspergillus Nidulans Var. Echinulatus, Raymond Kunito Fuji

Theses and Dissertations

The purpose of this investigation was to evaluate the possible taxonomic significance of the "rodlet" patterns and spore wall configurations of conidia from monosporous cultures of Penicillium digitatum Saccardo and Aspergillus nidulans Eidam var. echinulatus Fennell & Raper. Freeze-etching the conidiospores from single spore isolates of these fungi revealed that spore wall patterns and configurations vary much too greatly to be of taxonomic importance on the strain and subspecies level. Environmental factors and genetic influences are discussed as possible mechanisms causing the variations of the spore wall configurations. A membrane-like structure that covers the "rodlet" patterns and which hinders spore …

A Study Of Folic Acid Dependent Reactions In Bovine Brain, Dillard Spencer Broderick

Theses and Dissertations

The enzymatic interconversion of serine to glycine and N5, N10-methylene tetrahydrofolate to N5 -methyl tetrahydrofolate have been studied in a cell-free system derived from bovine brain. A partial purification of serine transhydroxymethylase and N5, N10 -methylene tetrahydrofolate reductase has been achieved by ammonium sulfate fractionation, protamine sulfate fraction, and by various column chromatography procedures. The two enzymes studied catalyze sequentially the reductive transfer of the hydroxymethyl group of serine to the N5 position of tetrahydrofolate forming N5 -methyl tetrahydrofolate. The products of these reactions were assayed by the incorporation of C14 from a one-carbon precursor i.e., L-beta-(C14)-serine, or N5 -methyl …

A Study Of Conifer Invasion Into Meadows Surrounding Small Lakes And Ponds In The Trial Lake Region Of The Western Uinta Mountains, David Harvey Firmage

Theses and Dissertations

The object of this study was to determine whether or not Lodgepole pine is successfully invading meadows near ponds in the western Uinta Mountains as a preliminary step to the invasion of the Spruce-Fir climax forest. Line transects were established at three sites near Trial Lake extending from forest to wet meadow. Along these transects the soil was studied to determine percent organic matter, pH, depth to mineral soil, and texture. Also the depth of the water table was measured and the topography plotted. The age and size of the trees along the transect was determined, and the extent of …

Phylogenetic Relationships Of Purshia Tridentata And Cowania Mexicana, Stewart C. Sanderson

Theses and Dissertations

Because of the greatly increased supply of genetic variation which it provides, introgression is of great importance in determining both the rate and the direction of evolution. Hybridization between the genera Cowania and Purshia provides an excellent model for demonstrating the various products which might be expected from introgression. The present study is an attempt to further investigate phylogenetic relationships of Cowania mexicana and Purshia tridentata by use of cytological and biochemical techniques.

The Effect Of Chemical Adjuvants Of The Survival Of The Free-Living Stages Of The Gastrointestinal Nematode, Haemonchus Contortus, Anthony T. Chang

Theses and Dissertations

Considerable research has been done on the influence of various chemical adjuvants, such as glycerol and dimethyl sulfoxide (DMSO) on the survival of protozoan organisms. (Levine and Marquardt, 1955; Levine, Mizell and Houlahan, 1958; Levine, et al. 1962; Levine and Andersen, 1965, 1966; Fitzgerald and Levine 1957 1 1961; Diamond, 1964). Considerably less work has been done on metazoan parasites. The effects of various chemical adjuvants on the survival of Haemonchus contortus, the large stomach worm of sheep, at extremely low temperatures has not been reported. The purpose of this research was to determine if different concentrations of chemical adjuvants …

The Food Habits Of The Gila Mountain-Sucker, Pantosteus Clarki (Baird And Girard), Gail C. Kobetich

Biology ETDs

Intestinal contents of postlarval to adult Gila mountain-suckers, Pantosteus clarki (Baird and Girard), collected from the upper Gila River system, were examined using a slightly modified Sedgewick-Rafter counting technique. From the analysis of the intestinal material it was found that the diet of Pantosteus clarki consisted of 97.4% plant material, 2.4% animal material, and 0.2% organic detritus. In order of importance the plant material consisted of filamentous green algae, filamentous blue-green algae, and diatoms. The animal material consisted of aquatic invertebrates with the following groups being most important: Tendipedidae, Epherneroptera, Simuliidae, and Pyralididae. Other algal types and invertebrates groups occurred …

Inhibition Of Asexual Reproduction In Planaria, Lewis Hafen Leavitt

Theses and Dissertations

Asexual reproduction in the decapitated planaria, Dugesia dorotocephala, is inhibited by an extract of homogenized heads of the same or closely-related species. Decapitated planaria allowed to regenerate have reproduced asexually over 80% of the time, while those that have been cultured in a suspension of head homogenate have had asexual reproduction inhibited to less than 10%. The substance that inhibits asexual reproduction is heat labile. It requires a concentration of 2.0 heads/ml that contains .13 mg protein/ml to effectively inhibit asexual reproduction. A similar concentration of head homogenate from the related planaria, Dugesia tigrina, also contains the inhibitory substance. Head …
