Prisijungti Registracija

Both self-cured and UV-cured resin-base dental materials are used in preventive, restorative, and orthodontic dentistry. Polymerization is initiated in both systems by free radicals. Self-curing materials generate free radicals by means of chemical compounds included in their formulation. UV-curing

Influence of drug release rate on systemic timolol absorption from polymeric ocular inserts in the pigmented rabbit.

Prisijungti Registracija

There is an expectation that ocular inserts, regardless of the nature of the polymer, will faithfully reduce systemic drug absorption. This may not necessarily be so, however, since not all polymers would release drug at the same rate and to the same extent. The objective of the present study was to

Asararenes--a family of large aromatic macrocycles.
