Male Anorexia: In The Modern 2011, Barbara Wallen-Adams

McNair Poster Presentations

It has been reported that homosexuality is a risk factor for males with anorexia. However, it is unclear whether it is a specific risk factor for eating pathology or just a common risk factor associated with psychopathology. If social stigmatization of homosexuality can cause general psychological suffering that express itself as a discomfort with sexual orientation, poor self-esteem, depression, and disordered eating, than homosexuality may act as a general risk factor in itself. It can also be interrelated to certain aspects that distinctively increase the risk for males developing anorexia, such as increased identification with the male gender roles (Munen …

Destruction Of Biological Tetrapyrrole Macrocycles By Hypochlorous Acid And Its Scavenging By Lycopene, Dhiman Maitra

Wayne State University Dissertations

Hypochlorous acid (HOCl) is a potent oxidant generated by the hemoprotein myeloperoxidase. Although HOCl plays an important role in the innate immune response,sustained high levels of HOCl has been implicated to play a harmful role. In several pathological conditions such as atherosclerosis, endometriosis and sickle cell disease where HOCl is elevated there are reports of significant free iron accumulation. Free iron is toxic since it can lead to the generation of other secondary free radicals such as hydroxyl radical by Fenton reaction. The exact source and mechanism by which the free iron is generated is not clearly understood. This work …

The Role Of Histone H4 Biotinylation In The Structure Of Nucleosomes, Nina A. Filenko, Carol Kolar, John T. West, S. Abbie Smith, Yousef I. Hassan, Gloria E. O. Borgstahl, Janos Zempleni, Yuri L. Lyubchenko

Department of Nutrition and Health Sciences: Faculty Publications

Background: Post-translational modifications of histones play important roles in regulating nucleosome structure and gene transcription. It has been shown that biotinylation of histone H4 at lysine-12 in histone H4 (K12Bio-H4) is associated with repression of a number of genes. We hypothesized that biotinylation modifies the physical structure of nucleosomes, and that biotin-induced conformational changes contribute to gene silencing associated with histone biotinylation.

Methodology/Principal Findings: To test this hypothesis we used atomic force microscopy to directly analyze structures of nucleosomes formed with biotin-modified and non-modified H4. The analysis of the AFM images revealed a 13% increase in the length of …

Lactobacillus helveticus CNRZ 32 is recognized for its ability to decrease bitterness and accelerate flavor development in cheese, and has also been shown to release bioactive peptides in milk. Similar capabilities have been documented in other strains of Lb. helveticus, but the ability of different strains to affect these characteristics can vary widely. Because these attributes are associated with enzymes involved in proteolysis or AA catabolism, we performed comparative genome hybridizations to a CNRZ 32 microarray to explore the distribution of genes encoding such enzymes across a bank of 38 Lb. helveticus strains, including 2 archival samples of CNRZ 32. …

Freshman Orientation Sessions Can Teach Incoming Students About Healthful Lifestyles, Marjorie Freedman, Jennifer Waldrop

Faculty Publications

Currently, 32% of college students are overweight or obese (body mass index ≥ 25),which is likely because many adolescents enter college with an elevated body mass index. Further, the transition from high school to college is associated with weight gain.On their own for the first time, freshmen have greater independence in all aspects of their lives. Increased independence, in turn, often results in changes in types of food and beverages consumed, and in overall eating and exercise patterns—changes that often affect weight gain. Although the popular media continues to perpetuate the “Freshman 15” myth, a recent meta-analysis reported freshmen gain, …

Point-Of-Selection Nutrition Information Influences Choice Of Portion Size In An All-You-Can-Eat University Dining Hall, Marjorie Freedman

Faculty Publications

There is limited information about point-of-selection nutrition information on food choices in all-you-can-eat university dining halls, where food cost is controlled. This pilot study examined effects of point-of-selection nutrition information (pictures of different portion sizes with corresponding nutrition information) on students' choice of French fries and salad dressing and portion size of French fries. Point-of-selection nutrition information significantly decreased percentage consuming “large” portions of French fries (p < 0.05) but had a limited effect on salad dressing choice. Surveys indicated that >99% of respondents (n = 359) recalled point-of-selection nutrition information; more females used point-of-selection nutrition information to determine portion size. Additional studies are needed to support these promising results.
