Chinese herb extracts can potentially be used for developing new cosmetic or health food ingredients. This study evaluates the tyrosinase inhibitory and antioxidant activities of Bifidobacterium bifidum-fermented extracts of 3 Chinese herbs: walnut, Moutan Cortex Radicis (MCR), and asparagus root. First, the herbs were extracted using distilled water, 95% ethanol, 50% ethanol, 100% ethyl acetate,...
There are many benefits for high-power Light Emitting Diode (LED) lamp including weightless, anti-seismic and small size and other advantages of energy saving lighting. And a vapor Chamber (VC) can replace the current five kinds of LED boards (PCB, MCPCB, IMS, CS, and DCBS) and become a new generation of high power LED vapor chamber-based plate resulting from the high heat transfer efficiency, light...
The vapor chamber has already been confirmed that its anti-gravity, high effective thermal conductivity and suited on the high heat flux of heat source as the integral heat spreader. This article describes how to evaluate the thermal-performance of LED vapor chamber-based plate with VCTM V1.0, which has existed in the thermal-module industry for a year or so especially in high power LEDs application...
Background: The mammalian cyclin kinase subunit (Cks) family has two members, Cks1 and Cks2, which were identified based on the protein sequence homology to yeast Cks. Overexpression of Cks1 and Cks2 has been reported to be associated with high aggressiveness and a poor prognosis in various malignancies, including gastric, breast and prostate carcinomas. Yet, whether Cks1 and Cks2 are overexpressed...
