Correction of lower limb deformities with fixator assisted nailing.

Introduction: Deformities of the lower extremities can be congenital or acquired. Various surgical treatments have been employed for such disorders including osteotomy followed by either external fixation, internal fixation or external fixator assisted internal fixation. The aim of surgery is correction of deformity and restoration of mechanical axis and joint line.

Fabrication of solid nanoparticles for drug delivery.

The use of nanoparticles in biotechnology presents a growing interest for the numerous possibilities offered by combining the world of materials, with its advanced technologies and their diverse properties, and the biological world, with its elaborate molecular architectures, properties and functions. Different nanoparticles are attractive for their intrinsic properties of optical transparency, controllable porosity, chemical inertness and biocompatibility. Various synthetic methods have been developed for preparing nanoparticles with well-controlled sizes and shapes.
