in this assay, the evaluation of lipophilicity of four ace-inhibitors and hydrochlorothiazide (hctz) with rp-tlc on cellulose layers was described using three binary solvent systems. the selected ace inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with hctz. in addition, the linea...
In this study, the influence of pH on interfacial energy distributed over the phospholipids-bilayer surface model and the effect of hydrophobicity on coefficient of friction (f) were investigated by using microelectrophoresis. An important clinical implication of deficiency in hydrophobicity is the loss of phospholipids that is readily observed in osteoarthritis joints. This paper establishes t...
Silicone rubber has excellent insulation properties such as good hydrophobic mobility and anti pollution flashover performance. It plays an important role in the power system provides guarantee for reliability of supply. However, due to erosion various harsh environments, especially wet environments rain snow, a large amount dirt water are easily attached surface insulating parts. not only redu...
In his famous 1959 review, Walter Kauzmann clarified important features of the thermodynamic stabilities of proteins. The hydrophobic effect is recognised as an important contributor to the stability of proteins and an important determinant of their structural patterns. As generally understood, it depends on the unusual properties of cold water and its interactions with nonpolar solutes. Here w...

The surface hydrophobicity of Klehsiella aerogenes is influenced by the presence of capsular (K) and lipopolysaccharide (0) antigens. Loss of both K and 0 antigens ( K 0 ) , but not the K antigen alone (K-O+), increased surface hydrophobicity and susceptibility to phagocytosis. Unheated serum (i.e., containing complement) increased the surface hydrophobicity and phagocytosis of the K-O+ and K 0...
Variations in surface hydrophobicity of six Lactobacillus strains with and without an S-layer upon changes in ionic strength are derived from contact angle measurements with low- and high-ionic-strength aqueous solutions. Cell surface hydrophobicity changed in response to changes in ionic strength in three out of the six strains, offering these strains a versatile mechanism to adhere to differe...
In this assay, the evaluation of lipophilicity of four ACE-inhibitors and hydrochlorothiazide (HCTZ) with RP-TLC on cellulose layers was described using three binary solvent systems. The selected ACE inhibitors had sufficiently different structures which can indicate the method suitability for their lipophilicity evaluation as the model substances in comparison with HCTZ. In addition, the linea...
We have undertaken atomistic molecular simulations to systematically determine the structural contributions to the hydrophobicity of fluorinated solutes and surfaces compared to the corresponding hydrocarbon, yielding a unified explanation for these phenomena. We have transformed a short chain alkane, n-octane, to n-perfluorooctane in stages. The free-energy changes and the entropic components ...
