Evaluation of angiogenesis with the expression of VEGF and CD34 in human non-small cell lung cancer
(American Association for Cancer Research, 2007-09)
Angiogenesis is an essential process in the progression of malignant tumors and the most potent angiogenic factor is the vascular endothelial growth factor (VEGF). On the other hand, the CD34 is an endothelial antigen that ...
Adherence of Packing Defects in Soluble Proteins
(American Physical Society, 2003-07)
For protein structure to prevail in water, its backbone hydrogen bonds must be shielded from water attack, requiring a cluster of “wrapping” nonpolar groups. Thus, underwrapped regions are adhesive, as exogenous removal ...
