Abstract: Disclosed is a finger prosthetic is provided that could be attached to an individual's hand. The finger prosthetic includes a midsection, a fingertip portion, and a ring. The midsection, the fingertip portion, and the ring could be 3D printed and customized via 3D scanning The finger prosthetic includes a torsion spring system that comprises a fabricated torsion spring, a cable, and a pin. When the individual flexes their PIP joint, tension is generated in the cable and the cable pulls on the prosthetic fingertip thus flexing the prosthetic DIP joint simultaneously. When the individual wishes to extend the prosthetic DIP joint, he/she simply extends the PIP joint, causing the torsion spring to extend the prosthetic DIP joint. When the PIP joint is at rest, the cable will release the tension and the torsion spring will cause the DIP joint to extend to its upright position.

Abstract: The present invention is a composition of matter comprising an edible, wholly or partially nondigestible low calorie fat material having a non-Newtonian pseudoplastic rheology at body temperature. In particular, at 100° F. (37.8° C.) the fat material has: (a) a viscosity of at least about 2.5 poise at a shear rate of 800 seconds−1, a viscosity of at least about 4.0 poise at a shear rate of 100 seconds−1, and a viscosity of at least about 15.0 poise at a shear rate of 10 seconds−1; (b) a yield point of at least about 2,500 dynes/cm2; (c) a thixotropic area of at least about 0.20×106 dynes/cm2-sec.; and (d) a liquid/solid stability of at least about 50%. The composition is useful as a substitute for triglyceride fats in low calorie fat-containing food products, and as a method for reducing serum cholesterol.

Abstract: A solvent-free transesterification comprising the steps of (1) heating a mixture of a polyol, a fatty acid lower alkyl ester, an alkali metal fatty acid soap, and a basic catalyst to form a homogenous melt; and (2) subsequently adding to the reaction product of step (1) excess fatty acid lower alkyl esters yields polyol fatty acid polyesters.
