Physiologically-Based Pharmacokinetic Modeling Of Acetaminophen Metabolism And Toxicity, David M. Ng, Ali Navid
Physiologically-Based Pharmacokinetic Modeling Of Acetaminophen Metabolism And Toxicity, David M. Ng, Ali Navid
STAR Program Research Presentations
Acetaminophen is a common analgesic and antipyretic. Metabolism of acetaminophen and acetaminophen-induced liver necrosis are predicted using physiologically-based pharmacokinetic (PBPK) modeling. Pharmacokinetic means the model determines where the drug is distributed in the body over time. Physiologically-based means the anatomy and physiology of the human body is reflected in the structure and functioning of the model. Acetaminophen is usually safe and effective when taken as recommended, but consumption at higher levels may lead to liver damage. Additionally, other factors such as alcoholic liver disease, smoking, and malnutrition affect the maximum safe dose of acetaminophen.

Ionic liquids (ILs) are promising as solvents to increase the efficiency of biofuel production; however, ILs are toxic to microbes used in the fermentation of liquid fuels. To engineer IL resistant biofuel hosts, environmental bacteria were screened for tolerance, and these were used to create gene libraries to test in E. coli. Future characterization of these libraries using molecular techniques will be used to identify genes that contribute IL-tolerance to transformed microbes.

There is an error in the units of the concentrations of potassium iodide and trehalose described in the experimental details on page 1581. The correct concentrations are 0.6 M potassium iodide and 0.3 M trehalose.

This article introduces fully enclosed microfluidic paper-based analytical devices (microPADs) fabricated by printing toner on the top and bottom of the devices using a laser printer. Enclosing paper-based microfluidic channels protects the channels from contamination, contains and protects reagents stored on the device, contains fluids within the channels so that microPADs can be handled and operated more easily, and reduces evaporation of solutions from the channels. These benefits extend the capabilities of microPADs for applications as low-cost point-of-care diagnostic devices.
Β-Casein–Phospholipid Monolayers As Model Systems To Understand Lipid–Protein Interactions In The Milk Fat Globule Membrane, Sophie Gallier, Derek E. Gragson, Rafael Jiménez-Flores, David W. Everett
Β-Casein–Phospholipid Monolayers As Model Systems To Understand Lipid–Protein Interactions In The Milk Fat Globule Membrane, Sophie Gallier, Derek E. Gragson, Rafael Jiménez-Flores, David W. Everett
Chemistry and Biochemistry
Phospholipid–protein monolayer films were studied as model systems to mimic the structure of the native bovine milk fat globule membrane (MFGM) and to understand lipid–protein interactions at the surface of the globule. Phospholipids extracted from bovine raw milk, raw cream, processed milk and buttermilk powder were spread onto the air–water interface of a Langmuir trough, β-casein was then added to the sub-phase, and Langmuir–Blodgett films were studied by epifluorescence microscopy and atomic force microscopy. In all films, β-casein was responsible for clustering of the sphingomyelin- and cholesterol-rich microdomains into larger platforms. This suggests that the same phenomenon may happen at …
