Application of least-squares Kirchhoff migration (LSM) to synthetic reverse vertical seismic profile data (RVSP) demonstrates that LSM reduces the migration artifacts, improves the image resolution and produces a more accurate image than the standard migration, but cannot completely recover the model reflectivity for AVO analysis because of the limited data coverage. The influence of incomplete...

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

objective(s):breast cancer is an important leading cause of death from cancer. stathmin and tau proteins are regulators of cell motility, and their overexpression is associated with the progression and bad prognosis of breast cancer. memantine, an n-methyl-d-aspartate (nmda) receptor antagonist, is the potential inhibitor of tau protein in neurons. this study determines the effect of memantine ...

Background: Colorectal cancer (CRC) is attributed as one of the most common malignancies worldwide. CD133 molecule, as a pentaspan transmembrane glycoprotein, confers stem cell-related characteristics, including self-renewal and multi-directional differentiation capability. CD133 plays important roles in the progression of CRC by conferring apoptotic resistance and migration ab...

objective: transplantation of mesenchymal stem cells (mscs) can promote functional recovery of the brain after hypoxic-ischemic brain damage (hibd). however, the mechanism regulating msc migration to a hypoxic-ischemic lesion is poorly understood. interaction between stromal cell-derived factor-1α (sdf-1α) and its cognate receptor cxc chemokine receptor 4 (cxcr4) is crucial for homing and migra...
