Example sentences for: cationic
How can you use “cationic” in a sentence? Here are some example sentences to help you improve your vocabulary:
The magnitude of change in t PTEF / t E was significantly correlated with the concentration of serum eosinophilic cationic protein (an inflammatory marker) [ 7].
For example, PEI has a very high cationic charge density, making it useful for binding anionic DNA within the physiological pH range [ 4] and forcing the DNA to form condensates small enough to be effectively endocytosed [ 5], which is the primary mode of the PEI/DNA complex into the cell [ 1, 6, 7].
Resistance to polymyxin B is also imparted by the absence or masking of critical binding sites required for polycation-mediated permeabilization of the outer membrane [ 54 ] . Thus, attachment of polymyxin B to Yersinia enterocolitica is reduced by steric hindrance generated by the size and/or branched shape of the outer core region of its LPS macromolecule [ 55 ] . Additionally, resistance to cationic peptides can be due to cytoplasmic clearance of the antimicrobial peptide by an efflux pump; e.g., Yersinia resistance to polymyxin B caused by the RosA/RosB efflux pump/potassium antiporter [ 56 ] and Neisseria gonorrhoeae resistance to protegrin PG-1 via an energy-dependent efflux system termed mtr [ 57 ] .
Tetraethylammonium is known as a pore-occluding blocker of voltage-gated potassium channels [ 1 ] , but it also blocks other cationic channels such as calcium-dependent K +channels [ 2 3 ] and the nicotinic acetylcholine receptor [ 4 ] . TEA at 0.1 to 10 mM also inhibits osmotic water flux through human AQP1 channels expressed in Xenopus oocytes, decreasing the net swelling rate in hypotonic saline by 30-40% as compared to AQP1-expressing oocytes not treated with TEA [ 5 ] . This blocking effect on osmotic water flux was demonstrated to involve AQP1 channels specifically by using site-directed mutagenesis (tyrosine 186 to phenylalanine) to generate a Y186F AQP1 channel that is insensitive to block by TEA, but retains sensitivity to block by mercury.
Synthetic vectors include cationic polymers such as polyethyleneimine (PEI) and polylysine, as well as cationic lipids such as Lipofectamine [ 2] and negatively charged liposomes [ 3].
