A novel coated prosthesis that can be tailored to avoid the problem of bone resorption caused by stress shielding. The permanent, load-bearing skeletal replacement prosthesis is coated or covered with a bioabsorbable polymer at selected sites on its surface so that bone affixation is preferentially delayed at these covered sites and bone adjacent to uncoated areas are not stress shielded. Thus, re...

Optically active substances and biomolecules such as peptides, amino acids and nucleic acids are sensitive to elevated temperatures, extreme pH values and/or long reaction times. During chemical synthesis, therefore, these molecules easily become racemised or denatured. The inventive method provides mild reaction conditions for saponification, ammonolysis or transesterification of acid derivatives...

A heated air delivery system for vans, trucks and buses which has a single heated air distribution compartment located beneath the dashboard and designed to deliver heated air to defrost the entire windshield through a single elongated tapered defroster discharge nozzle located along the center of the dashboard. The heated air distribution compartment is also designed to deliver heated air to othe...

The system includes a cleaning fluid pump for delivering pressurized cleaning fluid to spray nozzles attached to either a floor nozzle ar a hand tool. Both the floor nozzle and the hand tool are connected to the suction and clean...

A pharmaceutical composition comprising isocaproyl[Ala<7>, Aib<10,17>, Lys(For)<11,18>, Lys (desoxyfructosyl <24>)]-salmon calcitonin-(5-32) which, when administered transmucosally, e.g. orally, has potent hypocalcemic activity. The composition may comprise a bile acid as resorption enhancer, and may be in capsule or liquid form.

This element is characterised in that it includes a reservoir of fluid (14) and means (15) for transfer of fluid between the reservoir (14) and the shock-absorbing (damping) chambers delimited in this element, driven as a function of the state of compression or relaxation of the element, in order to control the volume of fluid in the chambers, and therefore the pressure of gas in order to adapt th...
