An overview of nutraceuticals: current scenario.

Using food products to promote health and cure disease is renowned. Currently, most of the drug molecules available in the formulations were anciently used in their crude form. Dr Stephen De Felice first coins the term nutraceutics in 1989 to provide medical or health benefits including the prevention and treatment of diseases.

Synthesis of high aspect ratio quantum-size CdS nanorods and their surface-dependent photoluminescence.

Colloidal CdS nanorods with diameters near 4 nm and narrow size distributions ( approximately +/-10%) were synthesized up to 300 nm long by a sequential reactant injection technique that utilizes phosophonic acids as capping ligands. The phosphonic acid strongly passivates the nonpolar CdS surfaces and sequential reactant injection provides controlled CdS formation kinetics to enable heterogeneous and facet-selective CdS deposition on the more reactive {002} surfaces. With this process, the nanorod length can be systematically increased by increasing reactant addition to extend nanorod growth.

Cerebriform nevus sebaceus: a rare entity.

We present a case of cerebriform nevus sebaceus in an 18-year-old boy. This form of nevus sebaceus is quite rare, in contrast to the relatively common linear variant.
