Cellular life emerged ∼3.7 billion years ago. With scant exception, terrestrial organisms have evolved under predictable daily cycles owing to the Earth's rotation. The advantage conferred on organisms that anticipate such environmental cycles has driven the evolution of endogenous circadian rhythms that tune internal physiology to external conditions. The(More)
This study aimed to explore the mechanism of adriamycin resistance in human chronic myelogenous leukemia cells. Proteomic approach was utilized to compare and identify differentially expressed proteins between human chronic myelogenous leukemia K562 cells and their adriamycin-resistant counterparts. The differentially expressed proteins were analyzed by(More)
The lung squamous cell carcinoma survival rate is very poor despite multimodal treatment. It is urgent to discover novel candidate biomarkers for prognostic assessment and therapeutic targets to lung squamous cell carcinoma (SCC). Herein a two-dimensional gel electrophoresis and ESI-Q-TOF MS/MS-based proteomic approach was used to identify differentially(More)
In this study, a novel benzothiazol- and benzooxazol-2-amine scaffold with antibacterial activity was designed and synthesized. Preliminary structure-activity relationship analysis displayed that compound 8t with a 5,6-difluorosubstituted benzothiazole was found to be a potent inhibitor of Gram-positive pathogens, and exhibited some potential against(More)
Recently, carbon nanotubes together with other types of conductive materials have been used to enhance the viability and function of cardiomyocytes in vitro. Here we demonstrated a paradigm to construct ECTs for cardiac repair using conductive nanomaterials. Single walled carbon nanotubes (SWNTs) were incorporated into gelatin hydrogel scaffolds to(More)
Carbon nanotubes (CNTs) offer a new paradigm for constructing functional cardiac patches and repairing myocardial infarction (MI). However, little is known about how CNTs enhance the mechanical integrity and electrophysiological function of cardiac myocytes. To address this issue, we investigated the regularity and precise mechanism of the influence of CNTs(More)
Adjuvants are important components of recombinant protein vaccines which are often poorly immunogenic. For decades, the search for new vaccine adjuvants has been predominantly empirical. In addition, combinations of more than one adjuvant plus antigen have been systematically studied. Plasmid DNA containing additional(More)
The extremogram is an asymptotic correlogram for extreme events constructed from a regularly varying stationary sequence. In this paper, we define a frequency domain analog of the correlogram: a periodogram generated from a suitable sequence of indicator functions of rare events. We derive basic properties of the periodogram such as the asymptotic(More)
SUBJECT To evaluate physicians' current practice, attitudes toward, and knowledge of cancer pain management in China. METHODS We conducted a face-to-face survey of physicians (oncologists, internists, hematologists) who are responsible for the care of cancer patient of 11 general hospitals in Sichuan, China between December 2011 and December 2013.(More)
Cancer-associated fibroblasts play a key role in tumor progression. It is conceivable that the breaking of immune tolerance of “self-antigens” associated with tumor cells and tumor stromal is an attractive approach for tumor immunotherapy. To test this concept, we used basic fibroblast growth factor (bFGF) to activate normal fibroblasts and used these(More)
