The Mouse Mammary Gland: A Tool To Evaluate The Environmental Chemical Butyl Benzyl Phthalate, And Approaches To Improve Regulatory Testing, Jessica Daum
Masters Theses
In the first part of this thesis, we utilize the mouse model to evaluate the environmental chemical Butyl Benzyl Phthalate. Due to lack of research on female exposure to BBP, this thesis focuses on quantifying the effects of gestational exposure on the female mammary gland Here male and female parental mice were exposed before mating and through pregnancy and lactation to one of three doses of BBP or the control via oral ingestion. After weaning, offspring were sacrificed at puberty or early adulthood and evaluated for altered mammary gland morphology or hormonal receptor expression. Results indicate a persistent statistically significant …
Developmental Exposures To Pfas Mixtures Impair Elongation Of The Exocrine Pancreas In Zebrafish (Danio Rerio), Emily M. Formato
Developmental Exposures To Pfas Mixtures Impair Elongation Of The Exocrine Pancreas In Zebrafish (Danio Rerio), Emily M. Formato
Masters Theses
Poly- and perfluoroalkyl substances (PFAS) are a class of bioaccumulative toxicants used in numerous industrial and commercial products. Perfluorooctanesulfonic acid (PFOS) alters pancreatic organogenesis during development, and perfluorohexanesulfonic acid (PFHxS) has been suggested as a replacement for PFOS due to its shorter carbon chain, but they are often found together in surfactants, such as legacy aqueous film-forming foam. This study investigates how developmental exposures to a PFAS mixture (PFHxS + PFOS) impact the developing exocrine pancreas. Zebrafish embryos (Tg(ptf1a:GFP)) were exposed to 0.01% DMSO, or 8, 16, 32 μM PFHxS alone, 16 μM PFOS alone, and 8, 16, and 32 …
Development Of Phase Change Thermal Storage Medium: Cooking With More Power And Versatility, Martin Osei
Development Of Phase Change Thermal Storage Medium: Cooking With More Power And Versatility, Martin Osei
Masters Theses
With an Insulated Solar Electric Cooker (ISEC), a 100 W solar panel directly cooks food while providing 5W off-grid electricity access; but it cooks slowly. Storing the day’s energy with phase change thermal storage allows ISEC to cook more rapidly as well as cook after sunset. The ISEC is made by sticking a 3ohm resistive to an aluminum pot (inner phase change assembly PCA) where another cooking pot fits. The resistive heater is surrounded by a bigger pot (outer PCA) that contains the PCM and is tightly sealed. The solar panel is connected to the resistive heater with a thermal …
