5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-n-(npentyl, ndodecyl)-salicyladiminato]copper(ii) [alkoxy=oncnh2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and ir spectra. all complex homologues are thermally stable. cyclic voltammetric studies indicated that all copper...

This review presents some examples obtained by molecular techniques in the study of non-ionic reverse micelles of poly(ethylene oxide) type surfactants: tetraethylene glycol mono-ndodecyl ether (C12E4), Triton X-100, and triblok copolymers poly(ethylene oxide)-blockpoly(propylene oxide)-blockpoly(ethylene oxide) (L62 and L64 Pluronics). By using specific spectral parameters of spin, fluorescenc...

EPR spectra of aqueous solutions of the singly charged surfactant nitroxide 4-[N,N-dimethyl-N-(ndodecyl) ammonium]-2,2,6,6-tetramethylpiperidinyl-N-oxy bromide-d16 (DCAT12) are studied as functions of the molar concentration, c = 0.1-8 mM, and the temperature from 273 to 353 K. This concentration range is below the critical micelle concentration, cmc, at which DCAT12 forms micelles. Spin-spin b...

The interaction of sodium n-dodecyl sulphate (SDS) with histones in phosphate buffer pH 6.4 has been studied spectroscopically and by equilibrium dialysis. The enthalpies of interaction and the spectroscopic data suggest different structural stability for histones-SDS interaction. The linear relation between enthaly and absorbtion was determined by the equation of m= , where m is the sta...

Apolipoprotein B complexed with Triton X-100 (TApoB) has been isolated from human low density lipoprotein (LDL). Preparations are heterogeneous when analyzed by sedimentation velocity, with a major 12 S species and minor 17 S species present. The 12 S T-ApoB complex possesses a molecular weight of 880,000 containing 400,000 daltons of protein. Hydrodynamic measurements on this complex are consi...

5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladiminato]copper(II) [alkoxy=OnCnH2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and IR spectra. All complex homol...

INTRODUCTION: Implant associated infections contribute to increased patient morbidity and cost. We have previously reported that surface modification with certain hydrophobic polycations, such as N,Ndodecyl,methyl-polyethylenimine, renders implants bactericidal. Adhesion of serum proteins to the implant and low vascularity in the area of trauma create an ideal environment for bacterial adherenc...

TRPV3 is a thermosensitive ion channel primarily expressed in epithelial tissues of the skin, nose and tongue. The channel has been implicated in environmental thermosensation, hyperalgesia in inflamed tissues, skin sensitization and hair growth. While TRP channel research has vastly increased our understanding of the physiological mechanisms of nociception and thermosensation, the molecular me...
