THERE IS NOW SIGNIFICANT LITERAture showing that psychological stress can down-regulate various aspects of the cellular immune response. It is also established that communication between the central nervous system and the immune system occurs through bidirectional signals linking the nervous, endocrine, and immune systems. Psychological stressors affect the(More)
Host⋅guest complexes between cucurbit[7] (CB[7]) or CB[8] and diamantane diammonium ion guests 3 or 6 were studied by (1) H NMR spectroscopy and X-ray crystallography. (1) H NMR competition experiments revealed that CB[7]⋅6 is among the tightest monovalent non-covalent complexes ever reported in water with Ka =7.2×10(17)  M(-1) in pure D2 O and 1.9×10(15) (More)
The current study forms part of an ongoing research effort focusing on the elucidation of the chemical structure of the sulfated extracellular polysaccharide of the red microalga Porphyridium sp. (UTEX 637). We report here on the chemical structure of a fraction separated from an acidic crude extract of the polysaccharide, as investigated by methylation(More)
The solid state structures of (+/-)- and (+)-nefopam hydrochloride (3,4,5,6-tetrahydro-5-methyl-1-phenyl-1H-2,5-benzoxazocine hydrochloride, 1) were determined by single crystal X-ray diffraction analysis. (+/-)-Nefopam hydrochloride gave crystals belonging to monoclinic P21/c space group, and at 298 K: a = 11.766 (1) A, b = 7.741 (1) A, c = 16.907 (3) A,(More)
A rapid, sensitive, and quantitative novel immunoassay [FluoroChrome ImmunoAssay, FCIA] technique was developed which auspiciously combines both the high sensitivity of fluorescence measurements with the high specificity of an antibody. As opposed to existing immunoassays, FCIA is performed without separation of antibody-bound haptens from those that are(More)
A combined fluorescence-photochrome approach was used for investigation of the molecular dynamics antiDNP antibody binding site and its cavity. A 4-(N-2,4-dinitrophenylamino)-4'-(N,N'-dimethylamino)stilbene (StDNP) fluorescence DNP analog was incorporated into the antibody binding site. This was followed by measurements of fluorescence and photochrome(More)
A new experimental approach has been developed to study the distribution of local electrostatic potential around specific protons in biologically important molecules. The approach is the development of a method denoted as "spin label/spin probe," which was proposed by one of us (. Mol. Biol. 6:498-507). The proposed method is based upon the quantitative(More)
A fluorophore-nitroxide free radical dual-functional probe (FN) was utilized to study the kinetics of ascorbate (AH(-)) binding to Bovine Serum Albumin (BSA). Since the free radical fragment in the FN probe intramolecularly quenches fluorescence, ascorbate reduction of the nitroxide function is accompanied by a concomitant fluorescence intensity increase(More)
