Endocrine-Disrupting Properties Of Pharmaceuticals And Personal Care Products (Ppcps): An Evaluation Using Aquatic Model Organisms, Manahil Monshi Jan 2017

Endocrine-Disrupting Properties Of Pharmaceuticals And Personal Care Products (Ppcps): An Evaluation Using Aquatic Model Organisms, Manahil Monshi

Wayne State University Theses

Thousands of chemicals have introduced into the environment as a result of human activity since the industrial revolution, and the U.S. Government Accountability Office has estimated that as many as 1,500 new chemical entities are synthesized each year ("Key Issues: Toxic Chemicals - High Risk Issue," 2017). Many of these chemicals are now found in surface water and ground water and can have detrimental effects on environmental health and on human health. This anthropogenic contamination has resulted in the labeling of the diverse array of chemicals found in water, which are not routinely monitored or regulated, as contaminants of emerging …

Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph Aug 2016

Synthetic And Biological Exploration Of (+)-Boldine - Identification Of Potential Cns Receptor Ligands, Sujay Joseph

Theses and Dissertations

(+)-Boldine, an aporphine alkaloid, is reported to be biologically active at various Central Nervous System(CNS) receptors. However, only a few Structure Activity Relationship(SAR) studies have been conducted using boldine’s aporphine scaffold. A library of novel analogs was synthesized from boldine to understand the effect of bisbenzylation at C2 and C9 positions on the affinity and selectivity at the serotonin receptors.

Exploration Of The Srx-Prx Axis As A Small-Molecule Target, Murli Mishra Jan 2016

Exploration Of The Srx-Prx Axis As A Small-Molecule Target, Murli Mishra

Theses and Dissertations--Toxicology and Cancer Biology

Lung cancer is a leading cause of cancer-related mortality irrespective of gender. The Sulfiredoxin (Srx) and Peroxiredoxin (Prx) are a group of thiol-based antioxidant proteins that plays an essential role in non-small cell lung cancer. Understanding the molecular characteristics of the Srx-Prx interaction may help design the strategies for future development of therapeutic tools. Based on existing literature and preliminary data from our lab, we hypothesized that the Srx plays a critical role in lung carcinogenesis and targeting the Srx-Prx axis or Srx alone may facilitate future development of targeted therapeutics for prevention and treatment of lung cancer. First, …

Species - Dependent Cardiac And Motor Responses To Cholinergic Stimulation In Daphnia Pulex And Daphnia Magna, Bryan James Hannan Jan 2014

Species - Dependent Cardiac And Motor Responses To Cholinergic Stimulation In Daphnia Pulex And Daphnia Magna, Bryan James Hannan

Wayne State University Theses

The role of acetylcholine (ACh) in regulating the activity of the heart and `feeding current' driven by the beating thoracic appendages of Daphnia pulex and Daphnia magna was evaluated using acetylcholinesterase inhibitors (AChE-I) and muscarinic receptor agonists. Single animals, tethered to a stainless steel pin, were tested in a watertight aquatic chamber that allowed free movement of appendages and swimming antennae. Heart contraction rate and the rate of thoracic appendage beating were quantified optically by measuring fluctuating changes in light-intensity caused by movement. Physostigmine, neostigmine, oxotremorine, pilocarpine as well as nicotine were used to study ACh and AChE. Atropine was …
