Nutritional Status And Growth In Infants With Cystic Fibrosis At Diagnosis And At Age Two Years And Six Years, Marianne Rich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

PURPOSE: A retrospective chart review was conducted to determine if nutritional source of feeding and/or infant age at diagnosis of cystic fibrosis had any effect on nutritional status and subsequent growth accretion. Additionally, an attempt was made to identify predictors for poor growth in patients with undiagnosed cystic fibrosis.

METHODS: Data was collected from medical and clinic charts at Primary Children's Medical Center (PCMC), Salt Lake City, Utah, for subjects born between January 1, 1995 and December 31, 200 I, who were diagnosed with cystic fibrosis before 1 year of age. Thirty-one subjects met inclusion parameters. These subjects were divided …

Physiological Importance Of 1,25(Oh)2D3 Membrane-Initiated And Nuclear Actions In Chickens As A Function Of Growth, And Maturation In Male And Female Chickens, Birgitta Larsson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is well established that l,25(OH)₂D₃ is a major regulator of calcium homeostasis. The steroid exerts its effects on its target organs by two mechanisms, a slow mechanism mediated by nuclear vitamin D receptors (nVDR), and a rapid mechanism mediated by the l,25(OH)₂D₃ membrane-associated rapid response steroid binding protein (l,25D₃-MARRS bp). In this dissertation, the physiological relevance of membrane initiated steroid signaling was investigated by studying the correlation of age in male and female chickens with the magnitude of responses to l,25(OH)₂D₃ in duodena from 7-, 14-, 28-, and …

A Lactic Culture Stimulant Blend From Kluyveromyces Fragilis And Whey, Steven L. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A buffered growth medium was developed that sustained a significantly greater concentration of various strains of Streptococcus lactis and Streptococcus cremoris than did milk. The active buffering ingredients of this medium were magnesium hydroxide, ammonium and sodium salts of phosphate and citrate. This medium was entitled Lactic Culture Buffered Growth medium (LABGRO) and possessed about 8 times the buffering strength between pH 6.6 and 5.1.

Significant differences in growth and acid production rates were noted among Prt+ and Prt- lactic strains evaluated. Also noted were significant differences in cellular acid production rates. The two Prt- strains having the slowest growth …

Investigations On Improvement Of Acceptability And Evaluation Of The Nutritive Value Of Processed Cabbage And Its Effects On The Tumorigenicity In Mice, Chareonsri Srisangnam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objectives of this investigation have been to study the acceptability and nutritive value of processed cabbage and to elucidate the effects of chronic administration of cabbage on the activity of a colon tumorigen, 1,2-dimethylhydrazine (DMH). The organoleptic unacceptability of cabbage in spite of its high nutritional and economic values governed the choice of this cruciferous vegetable for this work.

Cabbage samples were blanched with steam, chemical solutions, and microwaves. Microwave blanching led to a "burnt spot" effect and to a relatively greater loss in weight of the vegetable. Blanching in solution involved boiling of cabbage with a chemical solution …
