...rinology, toxicology, and other areas. Despite the complexity of P450s, much has been learned about their structures, mechanisms, and function. Dr. Guengerich will discuss some of his recent work on P450 including the kinetic analysis of steps in catalysis by human P450s, the analysis of factors within the sub...

UCSD researchers maintain stem cells without contaminated animal feeder layers

...s were developed but this added another measure of complexity to the culture system, Hayek noted. In recent studies in Wisconsin and Massachusetts, new feeder layers were developed, but they did not entirely eliminate the use of animal products. In the Hayek study, the animal-derived feeder layers are complete...

Two-part blood pressure control suggests new approach to hypertension therapy

...ns within the kidneys." The results illustrate the complexity of blood pressure regulation and suggest that maximal efficacy of hypertension drugs, including ACE inhibitors and angiotensin receptor blockers, requires complete blockade of receptors in both the kidney and outside of the kidney.

A puzzle piece found in unraveling the wiring of the brain

HOUSTON -- (April 21, 2005) -- The complexity of the brain and, more specifically, how nerve cells form billions of contacts when there are fewer than 30,000 human genes is still a scientific mystery. A team headed by Drs. Robin Hiesinger and Hugo J. Bellen at Baylor College of Medicine in Hous...

The Molecular Profiling Institute, Inc. launches MammaPrint for breast cancer patients

..."We believe this fee is reasonable considering the complexity and accuracy of the test. This amount is low compared to the economic and personal cost of unnecessary treatment or simply not treating a patient at high risk for recurrence," stated David Mallery, MPI's Executive Vice President. MPI utilizes IBM t...
