Also disclosed are a method for preparation of the catalytic domain of M. taiwanensis WR-220 keratinase, and use of the M. taiwanensis WR-220 keratinase.
Abstract:
Methods for reducing the growth of breast cancer cells in a subject by exposing the cells to nanoparticles, and irradiating with a focused, low to medium power ultrasound. The nanoparticles can be gold or magnetic nanoparticles. The nanoparticles can have a cancer drug attached, such as an antibody-based cancer drug.
Abstract:
Images of blood vessels of a body are obtained by injecting a refraction enhancement contrast agent into the blood vessels to increase a difference in refractive indices of the blood vessels and surrounding material. The blood vessels are irradiated with a penetrating radiation, and an image of the blood vessels is generated based on detected radiation. The image has visible edge enhancement features indicating boundaries of the blood vessels.
Abstract:
A novel UDP-Gal regeneration process and its combined use with a galactosyltransferase to add galactose to a suitable acceptor substrate. Also described herein are synthetic methods for generating Globo-series oligosaccharides in large scale, wherein the methods may involve the combination of a glycosyltransferase reaction and a nucleotide sugar regeneration process.
Abstract:
A durable on-column tunneled frit was developed for use in nanoflow UPLC systems. The frit was tunneled during sol-gel reaction. The tunneled-frit fabrication process is easy and reproducible in terms of back pressure and durability. This design creates low backpressure with high liquid flow, which is suitable for the nanoflowUPLC application. A short packing (2 cm C18 particle) tunneled-frit column was demonstrated to sustain 10,000 psi continuous liquid flow for over one week without any particle leakage or pressure instability. The tunneled-frit was also successfully applied to the fabrication of nanoUPLC trapping and analytical column system. It was demonstrated to have high separation efficiency and sensitivity for the analysis of tryptic peptides as well as improved detection sensitivity for phosphopeptide analysis.
Abstract:
The present invention relates to mutant gibberellin 2-oxidase (GA2ox) genes and uses thereof. In particular, the effective mutations disclosed herein can reduce GA2ox enzymatic activity to different extents, leading to various degrees of GA deficient yet beneficial agronomic traits in transgenic plants.

Abstract:
A piezoelectric actuating device includes a carrier, at least a piezoelectric unit, at least a linked component and a moving component. The piezoelectric unit is disposed on the carrier and includes at least a piezoelectric buzzer. The linked component is disposed corresponding to the piezoelectric unit. One end of the linked component is attached to the piezoelectric buzzer. The moving component is connected with the linked component. When the piezoelectric buzzer is actuated, it can carry the linked component to move correspondingly so as to move the moving component. The piezoelectric actuating device has the advantage of low cost and can achieve the sub-nanometer scale actuating resolution.
