Effect Of Long Term Rapamycin Treatment On Mtor Signalling Network In Colon And Liver Of C57bl/6 Mice, John Sorge

Wayne State University Theses

Many studies have investigated the effects of rapamycin on aging and cancer. However, the effects of long-term rapamycin supplementation on a cancer model have not been performed. This is the first study that investigates the effects of long-term supplementation of rapamycin in a cancer model. ACF analysis of colon tissues in mice showed no significant difference between controls and those supplemented with rapamycin. Factors such as energy balance, cellular environment, PI3K/Akt/mTOR pathway, and more have been assessed in this study. The duration of rapamycin supplementation seems to play an important role in the protection against cancer. Ultimately, this study suggests …

Kreider, Darryn S. Willoughby

Nutrition and Food Science Faculty Research Publications

The effects of a single bout of resistance exercise (RE) in conjunction with peri-exercise branched chain amino acid (BCAA) and carbohydrate (CHO) ingestion on skeletal muscle signaling markers indicative of muscle protein synthesis (MPS) were determined. It was hypothesized that CHO + BCAA would elicit a more profound effect on these signaling markers compared to CHO. Twenty-seven males were randomly assigned to CHO, CHO + BCAA, or placebo (PLC) groups. Four sets of leg presses and leg extensions were performed at 80% 1RM. Supplements were ingested 30 min and immediately prior to and after RE. Venous blood and muscle biopsy …

Eating Disorders: The Hidden Hormonal Effect On Fertility, Esther Tessler-Karfunkel

The Science Journal of the Lander College of Arts and Sciences

Women who have a history of eating disorders, specifically anorexia nervosa, are more prone to suffer from infertility. There are several hormones which are the driving force in this system and are therefore responsible for this. Fortunately, there are treatments which can help women with a history of eating disorders to reproduce. Using information found on Pubmed and Touro College’s database, this paper will discuss why the body cannot reproduce when it is lacking proper nutrition, as well as the various dynamics in the human reproductive system which are compromised when the body is not properly nourished.

Is Marital Status A Determinant Of Self-Monitoring Of Blood Glucose?, Jasmine Evelyn Dixon Jones

Electronic Theses and Dissertations

Glycemic control is one of the most important aspects of diabetes management and is necessary for the prevention or delay of complications associated with diabetes mellitus (DM). Self-monitoring of blood glucose (SMBG) is a technique used achieve glycemic control by revealing day-to-day changes in blood glucose levels. Since marriage protective effects have been shown for mortality, especially for men, it is useful to determine whether a similar relationship is found between marriage and SMBG. The purpose of this study is to examine whether marital status is a determinant of SMBG, when controlling for other variables, and whether marital status determines …

Evaluating Dietary Amino Acid Adequacy In Horses Using Isotopic Techniques, Sara L. Tanner

Theses and Dissertations--Animal and Food Sciences

Little is known about amino acid (AA) requirements in horses despite muscle mass accretion being of importance to an athletic species. Isotope methods for determining AA requirements and whole-body protein synthesis (WBPS) had not been previously used in growing horses. The first study herein was the first to apply isotope methods to determine WBPS in growing horses. In the study, weanling colts received two different levels of crude protein. Whole-body protein kinetics indicated that WBPS was greater when the weanlings were fed the diet with a greater crude protein content (P<0.05). The second study sought to determine a lysine requirement for yearling horses using the indicator AA oxidation (IAAO) method. Despite using six dietary levels of lysine; three above and three below the current recommendation, no breakpoint could be determined. Phenylalanine kinetics were not affected by lysine level (P>0.05), but plasma lysine increased linearly with lysine intake …

The program has continued for 20+ years without an evaluation as to whether it is achieving its objectives. This evaluation will also exhibit the programs strengths and weakness so it can continue to improve. …

Exploring The Relationship Between Emotional Brain Training, Stress, Depression, Food Addiction, And Weight, Bailey Regina Adams

Theses and Dissertations--Nutrition and Food Systems

Obesity is a complex issue; stress, depression, and food addiction, are several psychological conditions that can accompany an obesity diagnosis. Emotional Brain Training (EBT) was evaluated as a new approach to these conditions. Stress, depression, food addiction, and weight were assessed at baseline, after a seven week active intervention, and after a seven week no contact period. The final sample consisted of 26 obese adults. At seven week assessments, EBT participants experienced significant weight loss (p-value = 0.05) and decreased perceived stress (p-value = 0.035). Food addiction also decreased from 50% to 8.3% (or one participant). At fourteen week assessments, …

The Benefits Of Breastfeeding, Avery Kordus

Senior Honors Theses

Breastfeeding research is plentiful, and the majority of the literature shows that breast milk is the superior form of infant nutrition except in the rare circumstances of infant metabolic disorders, maternal drug use, or positive HIV status. In comparison to formula, breast milk provides improved cognition, development, behavior, bonding, nutrition, digestion, immunity, and long-term health with fewer diseases and conditions in infants. Mothers are benefited by breastfeeding through bonding, faster weight loss, and reduction in certain cancers and conditions. Breast milk contains the proper amount of carbohydrates, fats, proteins, vitamins, and minerals, and is also specialized for each infant and …

Lander College of Arts and Sciences Publications and Research

There is debate about the additive effects of exercise in conjunction with diet to treat obesity, and not much is known about the differential effects of strength versus aerobic training. This randomized controlled trial examined the effects of diet plus strength training, diet plus aerobic training, or diet only on metabolic risk factors associated with obesity. Eighty-one overweight and obese participants completed the 8-week intervention. All participants received an energy-restrictive formula diet with an energy content based on 70% of measured resting metabolic rate (RMR). Participants assigned to an exercise group trained 3 days/week under supervision. Anthropometrics and fasting hormones …

Department of Nutrition and Health Sciences: Faculty Publications

We are concerned that readers of the IOC paper will be confused and misled by the poorly referenced statements and frank (and sometimes dangerous) errors in the paper. The IOC authors should publish a correction of these and other errors noted. Broadening research of low energy availability in other groups, such as the male athlete, athletes of diverse ethnicities and the disabled athlete may help to advance science and may one day warrant introduction of a specific term for whatever serious clinical sequelae of energy deficiency may be discovered in future research on men.
