Polypeptide from Chlamys farreri (PCF) possesses strong antioxidant and photochemo-preventive properties. Our previous study has preliminarily demonstrated that PCF could reduce the intracellular reactive oxygen species (ROS) production and protect UVB-induced HaCaT cells apoptosis. But the anti-apoptotic effects of PCF on components of cell signaling(More)
Due to their properties such as superparamagnetism, high surface area, large surface-to-volume ratio, easy separation under external magnetic fields, iron magnetic nanoparticles have attracted much attention in the past few decades. Various modification methods have been developed to produce biocompatible magnetic nanoparticles for protein immobilization.(More)
OBJECTIVE To investigate the presence of miRNA-144 in the saliva of patients with esophageal cancer and its value for early diagnosis of esophageal cancer. METHODS Saliva samples were collected form patients with esophageal cancer admitted in the Fourth Affiliated Hospital of Jinan University and the First Affiliated Hospital of Guangzhou Medical College(More)
Mesenchymal stem cell (MSC)-mediated periodontal tissue regeneration is considered a promising method for periodontitis treatment. The molecular mechanism underlying directed differentiation and anti-inflammatory actions remains unclear, thus limiting potential MSC application. We previously found that insulin-like growth factor binding protein 5 (IGFBP5)(More)
Many large proteins have evolved by internal duplication and fusion. For proteins with internal structural symmetry, this means that their sequences should be made up of identical repeats. However, many of these repeat signals can only be seen at the structural level yet. We suggested a method of recurrent correlation analysis to detect the sequence repeats(More)
MARTE (Modeling and Analysis of Real-Time and Embedded Systems) is a profile of UML (United Modeling Language). MARTE provides support for specification, design and verification of real-time and embedded systems. Even though MARTE time model offers a support to describe multiform clocks, it lacks the ability to model both discrete and continuous behaviors(More)
OBJECTIVE To investigate the effect of CD59 gene inhibition mediated by RNA interference on the proliferation and apoptosis of non-small cell lung cancer (NSCLC) GLC-P cells in vitro. METHODS Recombinant plasmids for RNA interference of CD59 gene were constructed and transfected into GLC-P cells via lipofectamine 2000. The stably transfected cells were(More)
BACKGROUND The standard techniques of laparoscopic surgery were first used in the late 1980s, and this method rapidly developed into a safe and effective procedure that became the standard of care. Cardiac surgery has been the last surgical specialty to completely embrace endoscopic techniques. Our working hypothesis was that atrial-septal defect (ASD)(More)
Polypeptide from Chlamys farreri (PCF, M r = 879) is a novel marine active product isolated from gonochoric Chinese scallop Chlamys farreri which has been served as sea food for several thousand years. As an octapeptide, PCF consists of 8 amino acids, namely, Pro, Asn, Ser, Thr, Arg, Hyl, Cys, and Gly. PCF had been identified as a marine chemopreventive(More)
