It is important to note that not a lot of information is available regarding the chronic toxicity of Dicamba in humans‚ the U.S. EPA has not found any evidence regarding Dicamba disrupting the Endocrine system‚ and Dicamba is not likely to be a human carcinogen. Not as much data is available regarding Dicamba in aquatic species‚ but some baseline data exists. Immature coho salmon have a 24-hour LC50 (lethal concentration where 50% of the treated

integral regulators in the development of normal breast tissue‚ however it also plays a role in cancer development and progression (Martin et al‚ 2000). Tamoxifen is known as a selective estrogen receptor modulator (SERM)‚ it has been the “mainstay of endocrine therapy in breast cancer” (Martin et al‚ 2000). Tamoxifen is effective when used against estrogen receptor positive (ER+) breast cancers‚ problems arise when the breast cancer is estrogen receptor negative (ER-). We took two cell lines‚ MDA MB 231

Topic 6: Mammalian Pheromones Abstract A pheromone is a chemical signal which is released by one animal and received by another‚ which induce a species specific reaction. Pheromones are detected via chemosensory systems known as the Vomeronasal Organ (VNO). Within a wide range of mammals the VNO is used to elicit a generalized sexual response‚ primarily affecting the reproductive tract. This is seen in most terrestrial mammals who have adapted to sensing volatile chemical signals; the Mouse displays

designed to observe a baseline heart rate and blood pressure and to examine various modifications of the two. This experiment utilized both the BiopacPro and PhysioEx computer programs. The PhysioEx program was used to simulate a heart rate and modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure; while PhysioEx was again used to monitor the modifications to it. Heart rate was shown to decrease as temperature decreases‚ increase in the presence of epinephrine‚ and
