The Effect Of Hypercholesterolemia On The Membrane Lipids, 3-0-[¹⁴C] Methylglucose Transport, And 2,3-Diphosphoglycerate Levels In Rat Erythrocytes, Edwin J. Lester Jr.
The Effect Of Hypercholesterolemia On The Membrane Lipids, 3-0-[¹⁴C] Methylglucose Transport, And 2,3-Diphosphoglycerate Levels In Rat Erythrocytes, Edwin J. Lester Jr.
Loma Linda University Electronic Theses, Dissertations & Projects
An increase in dietary cholesterol and cholic acid will produce hypercholesterolemia in rats. For ten months, two groups of rats (six in each group) were fed commercial rat pellets (control group) or rat pellets plus cholesterol (1%) and cholic acid (0.25%) (experimental group). A blood sample from each animal was divided into three aliquots for three separate experiments on the erythrocytes: a membrane cholesterol and phospholipid determination, a 3-0-[14C] methylglucose (30MG) transport determination, and a 2,3-diphosphoglycerate (2,3 DPG) determination. The 30MG transport and 2,3 DPG aliquots were each incubated in the same five concentrations of 30MG and glucose …
A Morphometrical Analysis Of The Guinea Pig Placenta After Chronic Exposure To Carbon Monoxide, Marcella J. Woolsey
A Morphometrical Analysis Of The Guinea Pig Placenta After Chronic Exposure To Carbon Monoxide, Marcella J. Woolsey
Loma Linda University Electronic Theses, Dissertations & Projects
We used morphometric analysis to determine if placental structure is modified by carbon monoxide, Camm-Hartley guinea pigs were exposed throughout gestation to chronic conditions of carbon monoxide (averaging about 180 parts per million). Maternal weight, placental weight, fetal weight, and fetal length were recorded at the time of placental fixation. Using a computerized image analyzer on photomicrographs obtained through light microscopy, we measured maternal and fetal percent vessel volumes, surface areas, and vessel numbers. Maternal vessel numbers and surface area remained basically unchanged but decreased slightly. Maternal percent volume decreased 15%. However, fetal capillary number increased 35% (p < 0.01) from a control value of 2325 ± 184 per mm2 (SE …
Support Systems Of Mexican-American Women And Their Attitudes Regarding Infant Feeding, Susan Marie Krantz
Support Systems Of Mexican-American Women And Their Attitudes Regarding Infant Feeding, Susan Marie Krantz
Loma Linda University Electronic Theses, Dissertations & Projects
This was a descriptive study of 37 recently migrated to the United States, Spanish-speaking, Mexican-American women. Attitudes and support systems associated with their choice to breast or bottle feed their infants were studied. The purpose of this research was to answer the following questions:
1. What are the differences in the attitudes of Mexican- American primiparas who choose to breast feed and those who choose to bottle feed?
2. What are the differences in the practice, recommendations, and proximity of location of significant members of the women's support systems?
Twenty-one breast feeders and 16 bottle feeders were interviewed in Spanish …
Palynological Correlation Of The Kentucky No. 12 Coal, Gerald E. Vyhmeister
Palynological Correlation Of The Kentucky No. 12 Coal, Gerald E. Vyhmeister
Loma Linda University Electronic Theses, Dissertations & Projects
In attempting to analyze the depositional environment for the Kentucky No. 12 Coal three columns were sampled from a 1 km area. The columns yielded 76 miospore species belonging to 33 genera, and representing in decreasing order of abundance, arborescent lycopods, tree ferns, calamites, small ferns, gymnospermous trees, seed ferns, herbaceous lycopods, and others from unknown origin.
The pattern of spore distribution in the columns did not appear to be affected by the presence of several partings, a feature which calls into question several mechanisms proposed for the origin of partings and also creates difficulties for an autochthonous origin for …
Comparative In Vitro Studies On Bond Strength And Sealant Polymerization, Gerald E. Sievers
Comparative In Vitro Studies On Bond Strength And Sealant Polymerization, Gerald E. Sievers
Loma Linda University Electronic Theses, Dissertations & Projects
A comparison of two orthodontic sealants and two adhesives was made. An experimental adhesive was tested (Unitek*) also an experimental sealant (Unitek**) was evaluated for its ability to polymerize into a thin film. An established adhesive and sealant system (Concise***) was compared with the above products.
The factors which were considered important to the study were: the strength of the bond formed; the working efficiency; the ability for these materials to bond to the lingual of teeth; and the value of using contralateral teeth when testing bond strength.
An Instron testing machine was used to record the shear strength of …
