The Effects Of A Very-Low-Calorie-Diet On Resting Energy Expenditure, Body Composition, And Biochemical Data In Obese Outpatients, Charlene A. Perkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Obesity is a disease of major proportion in the United States. The Surgeon General has identified obesity as a national health problem that affects approximately 34 million Americans.

The aim of this study was to investigate the very-low-calorie diet, Optifast 70. Measurements for resting energy expenditure (REE} and body composition via circumference measurements (CBF} and infrared photospectromerty (NIR} with a Futrex 5000 were collected at weeks 1, 7, 13, 19, and 25. Biochemical data, including serum chemistry panel (SMA-12} and complete blood count (CBC}, were collected on weeks 1, 5, 9, 13, 17, 21, and 25. Lipid profiles were drawn …

The Relationship Between Cobalamin Deficiency And Neurological Dysfunction In Older Adults, Marion Bachra

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of cobalamin (Obi) deficiency among older adults is higher than among younger adults, and is estimated to be between 14% and 23%. Persistent Cbl deficiency can cause a variety of neurological deficits. Neurological dysfunction occurs commonly among older adults, raising the research question whether or not there is a relationship between the high prevalence of Cbl deficiency and neurological dysfunction among older adults.

This case-control study enrolled 120 subjects with and without neurological dysfunction through the Faculty Medical Offices' Internal Medicine and Neurology Outpatient Clinics. All subjects received a neurological and cognitive exam. Blood samples were drawn to …

A Comparison Of Iron Absorption In Adults And Infants Consuming Identical Infant Formulas, Richard F. Hurrell, Lena Davidsson, Manju B. Reddy, Peter Kastenmayer, James D. Cook

Manju B. Reddy

Fe absorption was estimated in adults and infants from the erythrocyte incorporation of Fe isotopes added to infant formula. Fe absorption was measured in adults using radioisotopes, and in infants with a stable-isotope technique. In adults, the geometric mean Fe absorption from a ready-to-feed soya formula with its native phytic acid content was 2.4%. This increased to 6.0 % (P < 0.05) after almost complete dephytinization. In infants, mean Fe absorption values were 3.9 and 8.7% respectively from the same products (P(O.05). In adults, mean Fe absorption from a spray-dried soya formula containing 110 mg ascorbic acid was 4.1 %, increasing to 5.3 % (P < 0.05) when ascorbic acid was doubled to 220 mgfl. In infants, mean Fe absorption values were 5.7 and 9.5 % (P < 0.05) from the same products. Mean Fe absorption from a milk-based formula was 6.5 % in adults compared with 6.7 % in infants. All meals in the adult and infant studies were fed using an identical meal size of 217 g. Increasing the meal size threefold in adults did not change fractional Fe absorption. Mean Fe absorption values for each meal were lower in adults than in infants, but the relative inhibitory effect of phytic acid and the enhancing effect of ascorbic acid were similar. We conclude that Fe absorption studies in adults can be used to assess the influence of enhancers and inhibitors of Fe absorption in infant formulas fed to infants. Further studies, however, are required to extend these findings to weaning foods and complete meals.

Wild Blueberry Research Reports

The 1997 edition of the Wild Blueberry Progress Reports was prepared for the Wild Blueberry Commission of Maine and the Wild Blueberry Advisory Committee by researchers at the University of Maine, Orono. Projects in this report include:

1. Investigation of processing damage of IQF blueberries

2. Use of sorter rejects and wild blueberry puree to prevent warmed over flavor in processed beef patties

3. Factors affecting the quality of IQF wild blueberries

4. Determination of pesticide residue levels in fresh and processed wild blueberries

5. Pollination ecology of wild blueberries in Maine

6. Control tactics for wild blueberry pest insects …
