Results of the investigation showed significantly elevated vitamin A, normal vitamin E, and decreased carotene levels in persons with renal failure receiving maintenance hemodialysis, when compared …


Quantitation Of Formaldehyde Resulting From Oxidative Deterioration Of Unsaturated Fatty Acids, Stanley J. Andrews May 1978

Quantitation Of Formaldehyde Resulting From Oxidative Deterioration Of Unsaturated Fatty Acids, Stanley J. Andrews

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Derivatives of 3-methyl-1-2-benzothiazolinone hydrazone were formed from the oxidation products of three oxidized unsaturated fatty acids. Aeration with oxygen and heat (65C) was used as a means of accelerating deterioration of lipid samples. Formaldehyde was recovered from oxidized pure standards of oleic, linoleic and linolenic acid methyl esters, and identified using gas chromatography. Formaldehyde was also recovered from oxidized lipid extracts of mechanic ally deboned turkey meat and turkey cluster fat. Gas chromatography was used to measure concentrations of unsaturated fatty acids during the oxidation of extracted lipids. Linoleic and linolenic fatty acids significantly decreased (p < .005) in oxidized lipid extracts from turkey cluster fat stored frozen for six months.

Measurement of the amounts …

A Field Study In The Use Of Dietary And Urinary Variables In Determining Osteoporosis In Elderly People, Jane Steger Osborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three-day dietary records were analyzed for nutrient content and 24 hour urine samples were analyzed for calcium, phosphorous, total nitrogen, and free alpha-amino nitrogen for 210 elderly people. Dietaries and urine samples were collected twice, October and March at five month intervals, for each subject. Increases were found in both dietary intake and urinary components October to March. Based on a criteria of high dietary protein, low dietary calcium, high urinary nitrogen and low calcium, 23 subjects were selected as osteoporotic and and 25 were selected as non-osteoporotic. This method of prediction was not supported by radiological evaluations.

A Longitudinal Study, Part Iii: The Relationship Of Weight, Health Status, Diet And Anxiety To Serum Cholesterol Levels In Adults, Kristine S. Saunders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over an 18-year period, beginning in 1955, a group of subjects has been studied six times to determine if any relationship exists among serum cholesterol levels, body weight, health status, diet quality and stress or anxiety. For the first four test periods, extending through ages 7 to 16 years, there were 321 subjects. Later, in 1968, 86 of the original 321 subjects, now aged 19-22 years, were able to participate in a follow-up study. The 1974 study was able to involve 30 of the original 321 subjects now aged 26-29 years. Findings show that from approximately the fifteenth year onward …


Essential Tyrosine Residues In Calf Liver Uridine Diphosphoglucose Pyrophosphorylase, E.C. 2.7.7.9., Robert Carl Bachmann May 1972

Essential Tyrosine Residues In Calf Liver Uridine Diphosphoglucose Pyrophosphorylase, E.C. 2.7.7.9., Robert Carl Bachmann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The catalytic necessity of tyrosine residues in uridine diphospho- glucose pyrophosphorylase [E.C. 2.7.7.9] was investigated. Chemical modification of the pyrophosphorylase by N-acetylimidazole indicated that tyrosine residues were essential for activity. Approximately 23 of 112 tyrosines per molecule of 475,000 Daltons could be 0-acetylated. Solvent perturbation difference spectroscopy supported this number of exposed tyrosine side chains and in conjunction with chemical modification indicated that at least 11 to 12 tyrosyl residues per protein molecule are fully exposed. it her subst rate, uridine t riphosphate or uridine diphosphoglucose, afforded significant protection against inactivation by N-acetylimidazole.

The significance of these tyrosine residues is …


Nutrition During Pregnancy, Lactation And Infancy, Minodokht Froozani May 1968

Nutrition During Pregnancy, Lactation And Infancy, Minodokht Froozani

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

In many countries in South and East Asia, most diets are defective in quality, even when there is not a severe shortage of food. They do. not provide an adequate quantity of essential nutrients. One of the most severe deficiencies is in good quality protein. The solution to this problem is to produce and provide the right kinds of foods and to establish national food production policies which should make it possible to plan a better balanced diet based on sound nutritional principles and modern knowledge of nutritional requirements. Some degree of undernutrition, over-nutrition, or malnutrition occurs in most European …


A Growth Study On Phenylketonurics, Emma Johnson Aitken Jun 1966

A Growth Study On Phenylketonurics, Emma Johnson Aitken

Loma Linda University Electronic Theses, Dissertations & Projects

Data from forty-eight medical records of phenylketonuria children under treatment were investigated to determine if growth, as measured by stature, was normal; and to determine if the state of control or the age at beginning of treatment had an effect on growth. Mean intakes of phenylalanine, protein, and calories were obtained on the nutritional data only if the simultaneous serum phenylalanine was equal to or less than 6 milligrams per cent. These means were grouped according to the age of the children into 7 groups (0

The height at beginning of treatment and the last measured height was compared with …

A Study Of Certain Convenience Foods With Reference To Purchaser, Cost, And Nutritive Value, Naomi Jensen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The various activities associated with the provision of food for feeding of the family traditionally have been functions of the home . One of the major enterprises of the homemaker in past years was to plan , produce or purchase , preserve , and prepare food daily for the family. The role of the homemaker today has changed from one of producer to one of purchaser. Hence, at least weekly, the selection of food at the market place involves not only the best use of her time but wise expenditure of her food budget. The market is changing so rapidly …

The Problem Of Low Solids-Not-Fat In Milk, Laurence C. Snook Jan 1960

The Problem Of Low Solids-Not-Fat In Milk, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

TO the consumer of milk, the solids-not-fat fractions is of prime importance.

This contains the protein, the minerals and the milk-sugar which collectively make milk such a valuable and palatable food.

If we wish to encourage increased consumption of milk as a health food it is essential that quality must be maintained and if possible improved.

Producers and distributors must always remember that if maximum sales are to be obtained, the needs of the consumer must remain paramount.


Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram Nov 1951

Reduced Ascorbic Acid Content Of Potatoes Grown With And Without Straw Mulching And Irrigation In Eastern Nebraska, H. O. Werner, Ruth M. Leverton, Mary R. Gram

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Potatoes harvested from home gardens and in commercial early-producing fields in the Midwest are an important low-cost source of ascorbic acid from late June into September. The major portion of the early commercial crop in Nebraska (harvested mostly in August) is produced with irrigation. Straw or litter mulching is a well established practice in the nonirrigated garden and farm potato patches. The value of these cultural methods for increasing yield is well known, but prior to this study little was known about their influence on the ascorbic acid content of the tubers, or about the persistence of any such influence …


One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh Apr 1942

One Hundred Studies Of The Calcium, Phosphorus, Iron, And Nitrogen Metabolism And Requirement Of Young Women, Ruth M. Leverton, Alice G. Marsh

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to add appreciably to the data available on the metabolism of calcium, phosphorus, iron, copper, and nitrogen of young women on their customary self-chosen diets. It was planned to use the figures for the retentions or losses of these dietary essentials which occurred at various levels of intake to determine the requirement of the subjects and to evaluate the adequacy of present adult dietary standards for young women. The fact that the girls were living on self-chosen diets warrants emphasis. A large proportion of the subjects were doing light housekeeping and brought much of their …
