Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters
Undergraduate Honors Theses
Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD+) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD+ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPRmt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD+ and through increasing levels …

Examining Perceptions Of Anorexia Nervosa, Polly Mcgonigle
Undergraduate Honors Theses
Anorexia nervosa (AN) is an eating disorder characterized by a restriction of energy intake, an intense fear of gaining weight, and often distorted body image. AN has the second highest mortality rate of all psychiatric disorders, due to high suicide rates and medical complications associated with malnutrition. An estimated 10% of those who have AN die because of the disorder (Insel, 2012). Interacting factors—genetic, biological, environmental, and psychosocial—contribute to the etiology and maintenance of AN. However, outside of research settings, AN is misunderstood as having primarily environmental roots (Salafia, et. al). Blame is placed on societal expectations and the disorder …
Dna Transfer In The Soil Bacterium Rhodococcus, Jaimin Maheshbhai Kapadia
Dna Transfer In The Soil Bacterium Rhodococcus, Jaimin Maheshbhai Kapadia
Undergraduate Honors Theses
Gene transfer plays an important role in bacterial evolution. Especially in an under explored species like Rhodococcus, a type of bacteria found in the soil. Rhodococcus has several applications in the pharmaceutical industry and in the production of antibiotics. Rhodococcus possess several unique sets of properties which makes it beneficial to have a reliable method of producing mutants of Rhodococcus. The goal of the experiment was to find an efficient way of forming Rhodococcus colonies with kanamycin resistant genes. The project began from an unexpected observation from an earlier experiment with Rhodococcus strain MTM3W5.2. where I attempted to transform this …
Effects Of Nicotinamide Riboside And Beta-Hydroxybutyrate On C. Elegans Lifespan, Jeffery Peters
Effects Of Nicotinamide Riboside And Beta-Hydroxybutyrate On C. Elegans Lifespan, Jeffery Peters
Undergraduate Honors Theses
The nicotinamide riboside (NR) form of vitamin B3and the ketone body ß-hydroxybutyrate (BHB) are two of the most promising natural compounds yet identified for the treatment of aging and aging-related diseases. Forms of vitamin B3are precursors for the synthesis of the coenzymes nicotinamide adenine dinucleotide (NAD(H)) and nicotinamide adenine dinucleotide phosphate (NADP(H)). In aged cells levels of NAD+decline, decreasing metabolism and decreasing activity of protective sirtuin protein deacetylases. In aged cells NR, but not more common forms of vitamin B3, boost NAD+levels. BHB is naturally produced by the body when individuals fast …
