Studies of Rho GTPases in Drosophila and Xenopus suggest that Rho family proteins may play an important role in embryogenesis. A reverse genetic approach was employed to explore the role of Rho GTPases in murine cardiac development. Cardiac-specific inhibition of Rho family protein activities was achieved by expressing Rho GDIalpha, a specific GDP(More)
Biology presents incomparable, but desirable, characteristics compared to engineered systems. Inspired by biological development, we have devised a multi-layered design architecture that attempts to capture many of the favorable characteristics of biological mechanisms for application to design problems. In this paper we have identified and implemented(More)
We present a method for constructing electronic circuits that uses analogues of biological multi-cellular development, genetic regulatory networks, and transcription and translation processes to build circuits. We show how small circuits may be evolved and how they may be reused to build larger circuits. We also demonstrate that the artificial ‘organisms’(More)
Early diagnosis and treatment of thyroid cancers are critical for better prognosis and better survival rates. The purpose of this study was to identify potential diagnostic markers for papillary thyroid carcinomas with distant metastasis. Fifty-eight papillary thyroid tumor specimens (27 papillary thyroid carcinomas with distant metastasis and 31 without(More)
BACKGROUND The prognosis for thyroid cancer differs between metastatic and non-metastatic cases. To identify biomarkers useful for thyroid cancer diagnosis and to establish a marker panel for the early detection of metastatic thyroid carcinoma, this study compared histomorphological features and biomarker expression profiles in thyroid carcinomas according(More)
An automatic versatile system which integrated solid phase extraction (SPE) with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was developed. Diverse commercial SPE columns can be used under an ambient pressure in this online system realized by a dual-dilution strategy. The first dilution enabled the direct injection of(More)
Cytokinins play a critical role in controlling plant growth and development, but it is difficult to be determined in plant samples due to the extremely low concentration level of picomole/gram. So it is important for efficient sample preparation with selective enrichment and rapid separation for accurate analysis of cytokinins. Herein, a supramolecular(More)
The biomarker identification of cancer is benefit for early detection and less invasion. Polyunsaturated fatty acid (PUFA) metabolite as inflammatory mediators can affect progression and treatment of cancer. In this work, the serum was collected from colorectal cancer patients and healthy volunteers, and then we tested the change of serum PUFA metabolites(More)
