Abstract: A pharmaceutical composition containing a mixed polymeric micelle and a drug enclosed in the micelle, in which the mixed polymeric micelle, 1 to 1000 nm in size, includes an amphiphilic block copolymer and a lipopolymer. Also disclosed are preparation of the pharmaceutical composition and use thereof for treating cancer.

Abstract: An improved structure of a signal transmission line is formed by a plurality of cables, and the material of the cables is polyamide or nylon. The cables are tightly wound with copper wires with good conductivity. Furthermore, an insulator covers the outer surfaces of the cables and copper wires. The material of the insulator is a nylon elastomer. The signal transmission line has a flat and bendable configuration. Since the material of the cables is polyamide or nylon with high tension-resistance, good flexibility and high heat-tolerance is obtained. Therefore, the signal transmission line is able to serve as a telephone wire or serves to transfer signals between computers or other communication devices.

Abstract: A silicon active analog filtering buffer apparatus and its method of operation is disclosed to receive an input signal and generates a synthesized output signal. The apparatus comprises a pulse generator for receiving the input signal and producing a sequence of delayed signal pulses in response to the input signal. A control logic circuit is connected to the pulse generator for generating scheduling on/off operation control signals. An array of switched current sources includes a number of switch means each connected to the control logic for receiving a corresponding one of the generated scheduling on/off operation control signals for shaping pre-determined waveforms. An output stage providing an amplified 15 current output for shaping to form the synthesized output signal. No complex computational procedure is necessary for the creation of the output filtered signal. Power consumption, as well as device physical dimensional characteristics are both reduced.
