The Effects Of Sex On Zebrafish Bone Metabolism, Simon Bagatto
The Effects Of Sex On Zebrafish Bone Metabolism, Simon Bagatto
Williams Honors College, Honors Research Projects
I investigated the effects of diet and sex on zebrafish bone metabolism. Zebrafish were subjected to either a high-calorie or low-calorie diet over a five-week period. After this diet, zebrafish scales were used to measure alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) enzyme activity with a fluorescent substrate. The enzyme activities were markers of the osteoblasts (ALP) and the osteoclasts (TRAP). These data were compared among sex and diet of the zebrafish using a repeated measures ANOVA statistical test. I also measured the number of resorption lacunae per scale (another indicator of osteoclast activity). The results showed higher TRAP …
Nicotine And E-Cigarette Effect On Maximal Metabolic Rate (Mmr) In Procambarus Clarkii, Nathan Cuttica
Nicotine And E-Cigarette Effect On Maximal Metabolic Rate (Mmr) In Procambarus Clarkii, Nathan Cuttica

The use of electronic cigarettes, commonly referred to as e-cigarettes or vapes, has increased exponentially in recent years despite the lack of research into potentially negative physiological effects. The rise in e-cigarette use is likely due to the overwhelming evidence regarding the addictive properties of nicotine and the damage caused by traditional tobacco cigarettes. Most e-cigarettes, however, still contain nicotine and are associated with a rise in nicotine-related intoxications (Belkoniene et al., 2019). There are nicotine-free e-cigarette options, which are gaining popularity, but it is unknown if they carry similar or other negative physiological effects. Studies involving e-cigarettes containing nicotine …
Effects Of Electronic Cigarettes On The Standard Metabolic Rate Of Crayfish, Frank Shaffer
Effects Of Electronic Cigarettes On The Standard Metabolic Rate Of Crayfish, Frank Shaffer
Williams Honors College, Honors Research Projects
This study aims to examine the relationship between e-cigarettes (both with nicotine and without) and the effects on the standard metabolic rates of crayfish. In this experiment, 42 crayfish were divided into three treatment groups and exposed to a designated solution of either a control solution or a solution containing e-cigarette (nicotine or non-nicotine) vapor. Their standard metabolic rates were then measured by using oxygen uptake as a proxy. The results of this experiment indicate that there is no statistically significant relationship between the use of electronic cigarettes and the standard metabolic rate of crayfish. However, this study can be …
