Community-based distributive medical education: advantaging society.

This paper presents a narrative summary of an increasingly important trend in medical education by addressing the merits of community-based distributive medical education (CBDME). This is a relatively new and compelling model for teaching and training physicians in a manner that may better meet societal needs and expectations. Issues and trends regarding the growing shortage and imbalanced distribution of physicians in the USA are addressed, including the role of international medical graduates.

Kinetic and molecular modeling of nucleoside and nucleotide inhibition of malate dehydrogenase.

We studied the inhibition of mitochondrial malate dehydrogenase (mMDH) by the nucleotides cAMP, AMP, ADP, ATP. The experimental kinetic studies showed that the nucleotides were competitive inhibitors and that cAMP was probably the most potent inhibitor. To explain these observations, we used molecular modeling to determine the location, orientation, and relative binding energy of the nucleotides to mMDH.
