The prevalence of obesity and obesity-related disorders have increased world-wide. In the last decade, the intestinal microbiome has become a major indicator of metabolic and gastrointestinal health. Previous research has shown that high-fat diet (HFD) consumption can alter the microbial composition of the gut by increasing the abundance of gram-positive bacteria associated with the onset of obesity and type 2 diabetes. Although, the most common form of obesity and metabolic syndrome intervention is exercise and diet, these recommendations may not improve severe cases of obesity. Thus, an important relevance of my project was to investigate whether the intake of an …

Anoxia tolerance is strongly correlated with tolerance to heat, desiccation, hyperosmotic shock, freezing, and other general stressors, suggesting that anoxia tolerance is broadly related to stress tolerance. Age affects the capacity of many animals to survive anoxia, but the basis to this ontogenic variation is poorly understood. We exposed adult Drosophila, 1, 3, 5, 7, 9, and 12 days past eclosion, to six hours of anoxia and assessed survival 24-hours post-treatment. Survival of anoxia declined strongly with age (from 80% survival for one-day-old flies to 10% survival for 12 day-old-flies), a surprising result since adult fly senescence in Drosophila is …
