Effect Of Dietary Factors On Mutagenesis, Metabolism, And Binding To Dna Of Benzo [A] Pyrene And Benzo [A] Pyrene 7, 8-Dihydrodiol, Robin E. Vance

Loma Linda University Electronic Theses, Dissertations & Projects

Ellagic acid (EA), a naturally occurring plant phenol, at concentrations of 5 to 50 pg/plate, inhibited rat liver S9 protein dependent benzo[a]pyrene (B[a]P)-induced mutagenesis in Salmonella typhimurium TA 100 by 30-81% and B[a]P 7,8-dihydrodiol (DHD)-induced mutagenesis by 29 to 75%. EA (5-40 juM) did not significantly affect the metabolism of B[a]P or B[a]P 7,8-DHD as determined by high performance liquid chromatographic analysis of the organosoluble fraction and by the quantification of watersoluble conjugates. At these concentrations EA inhibited 3 3 the covalent binding of [ H] B[a]P and [ H] B[a]P 7,8-DHD metabolites to calf thymus DNA by 5 to …

Dietary And Hormonal Evaluation Of Men At Risk For Prostate Cancer, Donald J. Pusateri

Loma Linda University Electronic Theses, Dissertations & Projects

Relationships between dietary nutrients and plasma and fecal estrone, estradiol-17β, testosterone, and plasma prolactin levels were studied in young Seventh-day Adventist men: 18 nonvegetarians (NV), 20 lacto-ovovegetarians (LOV), and 15 vegans (V). Blood samples and 3 d dietary records were obtained. Contemporaneously collected diet composites and stool samples were analyzed for fiber. The vegetarians consumed significantly more fiber than the omnivores, while NVs and LOVs consumed more saturated fat than the Vs. Although plasma steroid hormone status did not differ, the Vs had significantly higher fecal estrogen levels than the NVs or LOVs. Plasma prolactin levels were significantly higher in …

The Effects Of An Employee Fitness Program On Absenteeism And Health Care Costs, Brian C. Bell

Student Work

Health care expenditures in the United States have continued to climb at an alarming rate. In 1982, health care expenditures accounted for nearly $322.4 billion of the gross national product (U.S. Department of Health and Human Services, 1982). Health care expenditures are expected to consume nearly 12 percent of the nation's economic output by the year 1990, reaching nearly $756 billion in projected costs (Cullen and Towe, 1983). Although health care costs have climbed at an annual rate of less than 10 percent, these costs have continued to increase in the private sector, which currently absorbs one-fourth of the nation's …

A Plant Root Warmer For Studying Phytophagous Insect Development And Fecundity At Temperatures Below Host Plant Tolerance, D. H. Akey, G. D. Butler, J. W. Radin

Entomology Papers from Other Sources

A simple root-warming device maintains the plants' roots at a higher temperature than that at which the rest of the plant is held. This permits the host plant to retain turgor, not wilt, and therefore remain suitable for and attractive to phytophagous insects. The technique was demonstrated in a development and fecundity test using the cotton aphid, Aphis gossypii Glover, reared on cotton seedlings, Gossypium hirsutum L., at foliar temperatures of 10.0 and 12.5°C. Root temperatures were held at 20°C. The device was also tested at a foliar temperature of 7.5°C in an additional fecundity test. In a control test, …

Aspects Of The Ecology Of The Mesopelagic Fish Gonostoma Elongatum (Gonostomatidae, Stomiiformes) In The Eastern Gulf Of Mexico, Thomas M. Lancraft, Thomas L. Hopkins, Joseph J. Torres

Marine Science Faculty Publications

Gonostoma elongatum is an important mesopelagic fish found throughout the world at subtropical-tropical latitudes. This study examined its distribution, abundance and life history in the eastern Gulf of Mexico. The species was a strong diel migrator, found from 25 to 325 m at night and from 425 to 725 m during the day with small fish occurring shallower than large fish. Numerical abundance and biomass were high, rivaling the dominant species of myctophids in the Gulf of Mexico. There no obvious seasonal fluctuations in population abundance. G. elongatum is a protandric hermaphrodite whose population breeds throughout the year and females …

Interactions Between Aquatic Chromogenic Bacteria And Pathogenic Vibrio Spp., John Louis Harris

Biological Sciences Theses & Dissertations

Interactions between populations inhabiting an ecosys­tem are responsible, in large part, for determining which species coexist in that ecosystem. In this study, interac­tions between selected Vibrio species, V. alginolyticus and V. anguillarum, and marine heterotrophic, chromogenic bac­teria in aquatic microcosms were investigated. The ultimate goal of this project was to evaluate the feasibility of ex­ ploiting competitive interactions as a means to biologically control growth of the pathogenic marine bacteria, V. alginolyticus and V. anguillarum. In the majority of ex­periments (14/16), if chromogenic species were allowed to develop stable populations before a Vibrio spp. was intro­duced into a …

Nutrient Intake Of Marathon Runners, Janice V. Butler

Loma Linda University Electronic Theses, Dissertations & Projects

Three-day food records from a large group of marathon runners were analyzed and compared to various standards of dietary quality. Nutrient intake by the runners exceeded two-thirds the Recommended Dietary Allowance for all nutrients except for vitamin D and zinc in female runners. Energy and nutrient intake levels in the marathon runners were higher than those of the general US population except for fat and zinc in both males and females, and vitamin B12 in females. In general this group of runners consumed diets that would be considered more optimal than those of the general population. However, both caloric intake …

The Inhibition Of Bone Formation Occurring Under Weightlessness : The Effect Of Skeletal Unloading On Serum Levels Of A Bone-Derived Growth Factor, Jean D. Sibonga

Loma Linda University Electronic Theses, Dissertations & Projects

A deleterious effect of spaceflight on human health is the loss of bone associated with the prolonged lack of gravitational stress on the skeleton. A potential for bone loss is indicated by the hypercalciuria and decreased heel bone density determined in Skylab astronauts. Histological studies of juvenile laboratory rats in actual spaceflight and in simulation models document a suppression of bone formation with little alteration of bone resorption. The mechanism for net bone loss needs to be defined in order to develop measures for its prevention or correction.

Skeletal growth factors, which may mediate coupling and locally regulate bone volume …

Age-Related Changes In Meissner Corpuscles Of Diabetic Mice As Observed By Electron Microscopy, Vicky R. Ras

Loma Linda University Electronic Theses, Dissertations & Projects

Light touch and low-frequency vibration sense are often impaired in diabetic patients. Meissner corpuscles are distally located mechanoreceptors that respond to these stimuli. Peripheral sensory neuropathy in diabetes progresses from distal to proximal, therefore, Meissner corpuscles are ideally suited to study diabetic neuropathy in the C57BL/Ks (db/db) mouse.

Corpuscles from the forepaw digital pads of 9 diabetic and 9 nondiabetic littermates were studied by electron microscopy. These were divided into 3 age groups; 2.5 months, 10 months, and 17 months old.

Ultrastructural changes observed within various receptor components were myelin figures, multivesicular bodies, vacuoles, basal lamina duplication, abnormal and enlarged …

Heritabilities Of And Genetic Correlations Among Six Health Problems In Holstein Cows, H. K. Lin, P. A. Oltenacu, L. Dale Van Vleck, H. N. Erb, R. D. Smith

Department of Animal Science: Faculty Publications

Information from 7712 lactations of Holstein dairy cows was collected from 33 commercial herds around Ithaca, NY in the 3 yr from 1981 to 1983. The data were divided into subsets corresponding to lactation 1, lactation 2, and lactation 3 or greater. To estimate heritabilities of dystocia, retained placenta, metritis, ovarian cysts, milk fever, and mastitis, a mixed linear model (herd-year fixed and sire random effects) with 0 or 1 as the observed response was used. Variance components were estimated using Henderson's Method 3. The results show moderate heritabilities (.15 to .40) for dystocia, metritis, milk fever, and mastiffs and …

Ultrastructural Characteristics Of The Fetal And Neonatal Rat Urinary Bladder, Samuel M. Cohen, Martin Cano, Takao Sakata, Sonny L. Johansson

Scanning Microscopy

The embryologic and neonatal development of the normal rat urinary bladder was investigated in Sprague-Dawley rats by light, transmission, and scanning electron microscopy from day 11 of gestation through 21 days of age. The epithelium at day 11 of gestation is composed of small, loosely-connected, rounded cells with occasional short microvilli on their surfaces. The large polygonal cells characteristic of the adult bladder begin to appear by day 15, but the microridges are not apparent until day 17. By day 20, the epithelium appears morphologically similar to the adult bladder. Several morphological features are observed at different times of gestation …

A Reverse Genetics Approach For Studying Histone H4 Structure-Function Relationships In Yeast, Michael J. Bonaduce

Master's Theses

A previously constructed mutation of the histone H4 gene has been the subject of a detailed analysis. The mutation involves an H4 gene encoding two amino acid changes which substitute aspartic acid for glycine at positions 13 and 42 of the polypeptide. These substitutions result in a nonfunctional H4 protein when assayed in Saccharomyces cerevisiae. In contrast, an analysis of an amino terminal deletion of amino acids 3-26 results in a functional H4 protein. Physical biochemistry studies identify the sites of histone-histone interactions between residues 38-102 of histone H4, the same area in which position 42 resides. The question being …

The Effects Of An Aerobic Arm Cranking Program On Children With Myelomeningocele, Lisa L. Jacques

Student Work

The number of men and women with lower extremity disability is growing {Pollock, Miller, Linnerind, Laughridge, Coleman, and Alexander, 1974). A chief cause of this growth is an increase in the number of accidents damaging the spinal column (Pollock et al., 1974). However, many individuals are also born with these types of disabilities, and one of the causes is a disease termed spina bifida. Spina bifida occurs in about 3 per 1000 live births (Batshaw & Perret, 1981). The spine of children born with this defect is bifida and may be exposed, along with nervous tissue surrounding the area, on …
