Literature Review Elle, et al (2008) Elle, et al (2008) To view lipid stores in C. elegans: To view lipid stores in C. elegans: –Fluorescent microscope –Nile Red or Sudan Black B Picture 4 – C. elegans stained with Nile Red dye egans%20nile%20red.JPG
Literature Review Lila (2004) Lila (2004) Anthocyanins can help in many areas Anthocyanins can help in many areas –Visual acuity –Improved night vision –Regenerate rhodopsin –Obesity –Diabetes
Hypothesis Purpose To determine if anthocyanins fed as a whole berry can increase obesity in test subjects or if it has the same effect of purified anthocyanins and reduces obesity Null hypothesis: Anthocyanins fed as the whole blueberry will have no effect on the obesity levels in Caenorhabditis elegans Alternate hypothesis: Anthocyanins fed as a whole berry will increase obesity
Methodology Statistical analysis by T-test, p<.05, will be used to determine if the collected data is significant.
Protocols for measurement Use of fluorescence microscopy and vital dyes such as Nile red to view stained lipid droplets in the intestinal cells in live animals Use of fluorescence microscopy and vital dyes such as Nile red to view stained lipid droplets in the intestinal cells in live animals Use of Sudan Black B to stain lipid stores in dead animals Use of Sudan Black B to stain lipid stores in dead animals The Nile Red dye causes the lipid droplets to become highly fluorescent The Nile Red dye causes the lipid droplets to become highly fluorescent Picture 5 – C. elegans stained with Nile Red dye egans%20nile%20red.JPG
