Physical Fitness Activities For Latter-Day Saint Missionaries, Robert R. Hughes

Theses and Dissertations

The purpose of this study was to construct a physical fitness program for the needs of full-time missionaries of the Church of Jesus Christ of Latter-day Saints. Two groups, a control and experimental, were selected from the missionaries entering the Language Training Mission on February 16, 1972. The experimental group, consisting of thirty-two subjects, participated in a structured physical fitness class for seven weeks. The control group, consisting of twenty students, participated in no structured program. Each group took a pre- and post-test consisting of four strength factor tests and Cooper's twelve-minute run.

Findings of the study suggested no significant …

Polychlorinated Biphenyls: Uptake By Daphnia And Residues In Crayfish From The Willamette River, John J. Salmon

Dissertations and Theses

Polychlorinated Biphenyls (PCB's) are organochlorine molecules which find various industrial and product applications. PCB's are of concern to biologists because they are toxic substances which have become global contaminants. They are also of concern to biologists and analytical chemists because they interfere with the determination of some organochlorine pesticide residues. PCB's were discovered to be environmental contaminants after they showed up as unidentified peaks in pesticide analysis using gas-liquid chromatography with an electron capture detector (GLC-EC).

In the present experiment standard GLC-EC techniques were used to assay PCB's in Daphnia experimentally contaminated in the laboratory and in crayfish from the …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill

Masters Theses

Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.

The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …

Mechanisms Of Drug Distribution In Rat Submaxillary Gland In Vitro, James W. Putney Jr.

Theses and Dissertations

The access of drugs to variofis sites of action in the body is impeded by a succession of membranes. Likewise, the removal of a drug or foreign substance from the body is similarly dependent on the ability of the substance under consideration to permeate biological barriers. A con-committant problem generally arises concerning the overall time course of drug action: that of drug storage through binding or similar processes. Schanker (196h) however, has stated that "Although the mechanisms of localization and those of membrane transfer are in many respects different problems, there are some instances in which they are inseparable parts …

The stream ranges from 0.5 foot to 5 feet deep at a normal water level, with an average depth of 16 inches. It averages 12 feet wide, with a range from 4 to 20 feet.

A water quality study with 5 stations along the stream was conducted from January 1971 to July 1971. A qualitative benthos study at the same …

The Effects Of Desoxycorticosterone, Hydrocortisone, And Prednisone On Myogenesis In Vitro, Gregory K. Nienaber

Masters Theses

In order to obtain proper muscle development in tissue culture, certain conditions must prevail. There is a delicate balance of factors, and elimination of even one of these factors leads to poor and improper development. Muscle cells grown in the absence of fibroblasts usually fail to differentiate. Therefore, proper development depends upon the presence of two cell types: myoblasts and fibroblasts. Investigators have demonstrated that the fibroblasts are necessary in that they produce collagen which is necessary for proper muscle development. The present study has shown that desoxycorticosterone, hydrocortisone, and prednisone at concentrations of 10, 1, and 0.1 ug/ml of …

Preliminary Observations On The Effects Of Treflan To Fishes, P. Bradley Latvaitis

Masters Theses

Treflan E.C. is a selective, preemergence, soil incorporated herbicide. Preliminary tests were made to evaluate its effects at concentrations of 0.75, 1.275 and 1.8 p.p.m. on twenty species of fresh water fishes in the laboratory. The herbicide was proven to be a powerful fish toxicant. Centrarchus, Cichlasoma centrarchus, was the most resistant fish tested, while Bluegill, Lepomis macrochirus, was among the least resistant. Treflan E.C. decomposes and degrades rapidly. It was also found to interact with plastics. Further studies are necessary to provide a complete investigation of the effects of Treflan on Fishes.

Range And Optimum Growth Concentrations Of Phosphate And Nitrate For Chlamydomonas Reinhardtii, Thomas E. Hill

Masters Theses

A study was conducted on the alga Chlamydomonas reinhardtii to determine the range and optimum growth concentrations of phosphate and nitrate. There are only a few species of algae for which this type of data is known. Inorganic nutritional data is basic to the understanding of the complexities of phytoplankton ecology and eutrophication.

The "plus" strain of this heterothallic alga was cultured in a TRIS-buffered inorganic medium with various concentrations of sodium phosphate and potassium nitrate and adjusted to a pH of 7.4. The axenic cultures were evaluated at the end of 6 days with a spectrophotometer, at a wavelength …

Development Of A Flameless Atomic Absorption Assay For Mercury In Biological Materials And Levels Of Mercury Detected In Striped Bass (Roccus Saxatilis) Collected In The San Joaquin Delta, Patrick Glenn Burch

University of the Pacific Theses and Dissertations

The method for the determination of total mercury in biological material described in this paper comprises a destruction of organic matter by wet digestion, a reduction of the mercury by stannous sulfate, and circulation of the displaced mercury vapor in a closed system directly connected with an atomic absorption spectrophotometer Seven tissues from ten samples of locally obtained Roccus saxatilis (striped bass) were analyzed, and a three-fold elevation of mercury levels in the liver over the levels in the filet noted. See Table XIX for a comparison of the high, low, and average values for each tissue.

The author developed a game for the population in the study which was effective in teaching certain cognitive information about nutrition and appeared to be appealing to them. The development of the game included three main steps--review of commercial games, designing …

Pharmacological Effects Of A Bufadienolide Isolated From The Toad Bufo Boreas Halophilus, Roy Gordon Knickelbein

University of the Pacific Theses and Dissertations

For centuries, men have known that the skin of toads and other amphibians possess pharmacologically active compounds (Abel and Nacht,1911;Chen and Jensen,1929;Chen and Kovarikova,1967).All amphibians produce toxins in glands scattered over the skin .Many anuran amphibians have parotoid glands located on the lateral ,anterior ldorsal surface which are apparently specialized for the secretion of large quantities of toxin. W'eiss(1899) and Muhse(1909) describe the histology of these glands.

Aspects Of The Oculomotor System Of Callinectes Sapidus, Antoinette Steinacker

University of the Pacific Theses and Dissertations

An isolated perfused preparation was developed for the study of several aspects of the oculomotor system of the blue crab, Callinectes sapidus. The system for eyestalk rotation was investigated on an extracellular level. Two antagonistic pairs of muscles under visual and statocyst control were found to be responsible for stabilization and rotation of the eyestalk. The primary sensory input to the muscles appears to be from the statocysts, with both static position sense and dynamic acceleration components influencing the motor response. Two sensory feedback systems from mechanoreceptive hairs were found which influence the response of the eye stalks to statocyst …

Precipitable Hetero-Antibodies In Man To Animal Serum Proteins: Relation To Immunoglobulin Status, Hajime Hayashi, Gerald A. Logrippo, Mary Perry, Judene Mueller

Henry Ford Hospital Medical Journal

Immunologic studies show that man develops specific antibodies to a variety of serum proteins of bovine, sheep, goat, chicken, and rabbit origins as well as antibodies against cow's milk protein. The data in this report emphasize that these hetero-antibodies are more frequently found in individuals with immunological problems and/or chromosomal aberrations. The clinical significance of human hetero-antibodies against these animal proteins deserves closer clinical observation for an understanding of these immunological problems.

Carcinoma Of The Fallopian Tube, Victor Gantus, Bruce H. Drukker, C. Paul Hodgkinson

Henry Ford Hospital Medical Journal

Seven cases of primary carcinoma of the fallopian tube have been reviewed and compared with cases previously reported in the literature. Sterility was present in 51% of patients. There was a variety of symptoms, but the most frequent was vaginal discharge, in 42% of patients. Two patients manifested urinary symptoms and one patient ascites. In six of our seven patients, an adnexal mass was present. Although clinical diagnosis will always be difficult one should be highly suspicious of this disease in patients between 40 and 60 years of age with these symptoms.

The Symmetry-Decision Method Of Eeg Analysis, Richard M. Lee

Henry Ford Hospital Medical Journal

An improved version of a previously presented computer analysis for EEG is described. The basic process used in the analysis is the classification of waves according to duration (frequency) and amplitude. The unique aspect of the improved system is the distinction between "simple" waves and "composite" waves, which are slow waves with superimposed higher frequencies. The computer program makes this "decision" on the basis of wave symmetry.

Cecal Diverticulitis In The Japanese, Yasuhiko Kurosu, Tokio Suzuki, Toshinaka Koga

Henry Ford Hospital Medical Journal

Four cases of diverticular disease of the colon are reported. The disease is rare in Japan and is more commonly seen in the cecum. Differential diagnosis of right lower quadrant pain and a filling defect in the cecum on x-ray examination is evidence of diverticular disease of the cecum. The future trend of the disease of the colon is predicted as increasing because of older populations, changes in diet and more frequent recognition through barium enema examination.
