The promise of surgery, its scope and limitations in leprosy.

Leprosy is a systemic disease mainly manifested in skin and nerves. The nerves affected are the cutaneous and trunk nerves, especially those located superficially.

As a preliminary definition one could think of a model as an attempt to describe a certain process or system through the use of a simplified representation, preferably a quantitative mathematical expression, that focuses on a relatively few key variables...

Amine-Directed Hydroboration: Scope and Limitations

Iodine activation induces intramolecular hydroboration of homoallylic and bis-homoallylic amine boranes with good to excellent control of regiochemistry compared to control experiments using excess THF*BH 3. Deuterium labeling and other evidence confirm that the iodine-induced hydroboration reaction of homoallylic amine boranes occurs via an intramolecular mechanism equivalent to the classical ...
