Abstract: The invention surprisingly found that antcin or an ester derivative, salt or a composition thereof in combination with an anti-tumor drug provides unexpected efficacy in inhibiting tumors, while retaining normal cells at high viability. In addition, the amount of the anti-tumor drug in chemotherapy can be reduced by combinatorially using antcin or an ester derivative, salt or a composition thereof in view of the fact that they play a role in adjuvant therapy.

Abstract: This invention presents a fast and effective method to detect macromolecules such as peptides. Using a multifunctional chiral monomer, it combines molecular imprinting polymerization technology with a quartz crystal microbalance for detection of peptides to the ng/ml scale.

Abstract: Based on the direct formation of molecularly imprinted polymer on gold electrode, the present invention provides a peptide sensor for the detection of low-molecular-weight peptides. A new cross-linking monomer, (N-Acr-L-Cys-NHBn)2 is employed to attach the surface of the chip and to copolymerize with other monomers. Interestingly, N-benzylacrylamide participating both polymerization and recognition is carried out in an aqueous environment. Using quartz crystal microbalance detection, short peptides can be monitored by their interaction with plastic antibodies specific for the target peptides. The selectivity of molecularly imprinted polymer and the sensitivity of such artificial biosensors have collaborated to differentiate traces of oxytocin and vasopressin to the ng/ml scale.

Abstract: A main structure is intended to engage and disengage an flow-injection type piezoelectric sensor and is composed of a movable stand, a lifting mechanism, and a fixed injection portion. The movable stand is capable of being actuated by a rotary shaft of the lifting mechanism to move upwards or downwards. The movable stand is provided with a retaining slot capable of catching and releasing the flow-injection type piezoelectric sensor. When the movable stand is lifted, a transparent end of the fixed injection portion is in an intimate contact with a planar surface of the flow-injection type piezoelectric sensor which is caught in the retaining slot of the movable stand. A liquid test sample is thus injected into a charge channel of the transparent end such that the liquid test sample flows on the surface of a piezoelectric crystal located in an opening of the planar surface of the flow-injection type piezoelectric sensor for detecting the presence of a target molecule in the test sample.
