Objective: To assess the impact of a one-day clinical toxicology workshop in improving knowledge.
Methods: A one-day clinical toxicology workshop was conducted as a pre-conference workshop of the Annual Emergency Medicine Conference at the Aga Khan University Hospital, Karachi, in April 2012. The course was composed of poisoning-related common clinical scenarios. The pre-test and post-test understanding was used to assess the impact of the course in improving knowledge. The participants also evaluated the workshop as a whole thorough written evaluation forms. SPSS 19 was ued for statistical analysis of the data.
Result: There were 22 participants in the course. The …

Nanomaterials possess unusually high surface area-to-volume ratios and surface-determined physicochemical properties. It is essential to understand their surface-dependent toxicity in order to rationally design biocompatible nanomaterials for a wide variety of applications. In this study, we have functionalized the surfaces of silver nanoparticles (Ag NPs, 11.7 ±+2.7 nm in diameter) with three biocompatible peptides (CALNNK, CALNNS, CALNNE) to prepare positively (Ag-CALNNK NPs+ζ), negatively (Ag-CALNNS NPs−2ζ), and more negatively charged NPs (Ag-CALNNE NPs−4ζ), respectively. Each peptide differs in a single amino acid at its C-terminus, which minimizes the effects of peptide sequences and serves as …
Role Of P450 Enzymes In Tobacco Dependence And Lung Tumorigenesis, Lei Li
Role Of P450 Enzymes In Tobacco Dependence And Lung Tumorigenesis, Lei Li
Legacy Theses & Dissertations (2009 - 2024)
The overall aim of this study is to better define the roles of P450 enzymes, particularly those in the CYP2A, 2B, and 2F gene subfamilies, in the metabolism and actions of tobacco-related chemicals. Tobacco smoke contains numerous compounds that are deleterious to health, including the primary addictive component nicotine and procarcinogenic compounds, such as naphthalene (NA) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Our main hypotheses are i) that CYP2A and 2B enzymes are largely responsible for nicotine metabolism, and they can impact nicotine dependence; and ii) that CYP2A, 2B, and 2F enzymes play important and tissue-specific roles in NA and NNK bioactivation, leading …
Function And Regulation Of Intestinal P450 Enzymes : Insights From Conditional Cytochrome P450 Reductase Knockout Mouse Models, Yi Zhu
Legacy Theses & Dissertations (2009 - 2024)
The overall goal of this thesis work was to investigate the function and regulation of intestinal P450 enzymes (P450s). The central hypotheses are that 1) small intestinal (SI) P450s play an important role in the first-pass clearance of oral drugs and in bioactivation of chemicals that cause intestinal toxicity, 2) endogenous regulatory compounds produced by intestinal P450s are important for protection against chemical-induced colon inflammation, and 3) there is a cross talk between the liver and the SI that helps to maintain the overall xenobiotic-metabolism capacity of the digestive tract.
