<a href=lasix.autos/>hctz vs lasix</a> Given the importance of electrostatic and lateral elastic interactions for this selectivity, discussed previously 16, as well as the up regulation of anionic lipids such as phosphatidylserine and gangliosides in a wide range of tumor cells, we hypothesized that the extreme selectivity displayed by some W tagged peptides may translate also to selectivity between cancer cells and non malignant ones
