Abstract: Methods are described for targeting the release of an active pharmacological agent in an animal by administering that agent encapsulated in proteinoid microspheres which are stable to the environment encountered from the point of introduction until they migrate to the targeted body organs, fluids or cells and are there unstable. Orally administered delivery systems for insulin, heparin and physostigmine utilize encapsulating microspheres which are predominantly of less than about 10 microns in diameter and pass readily through the gastrointestinal mucosa and which are made of an acidic proteinoid that is stable and unaffected by stomach enzymes and acid, but which releases the microencapsulated agent in pharmacologically active form in the near neutral blood stream. Basic proteinoid microspheres encapsulating a dopamine redox carrier system are administered in the weakly basic, where they are stable, and then enter the blood stream, where the encapsulated agent is similarly released.

Abstract: By using titanium, titanium based alloys, or related metals or alloys, an orthodontic bracket can be manufactured which is lighter and stronger than any conventional type of bracket made of stainless steels, plastics and even ceramics.

Abstract: A hydrodynamic sprung surface bearing having at least two bearing elements bearing against a tube-shaped container which is filled with a substantially incompressible medium, and against which side walls bear. Surfaces of the bearing elements bearing against the container are, in total, smaller by one order of magnitude than a surface of the container wall. Even for scarcely progressive, low pressure forces, the preferably T-shaped or anchor-shaped bearing elements cause overturning in a negative stroke direction, along with a pronounced change in shape of the container, and positive arching and consequently a very large coarse contour adaptation stroke. Therefore, a positively supporting adaptation stroke of the bearing elements is achieved. Overturning results in two separate chambers which bring about an inherent progressive damping by effectively reducing streaming through of the substantially incompressible medium.
