cyclodextrins (cds) are a family of cyclic oligosaccharides which are composed of α (1,4) -linked glucopyranose subunits. thebest-characterized forms are α, β and γ cd which are consisted of six, seven and eight d-glucose units, respectively. cyclodextrins are produced from starch by enzymatic degradation. these macrocyclic carbohydrates with polar internal cavities can form complexes with and ...

in the present study, we investigated the effect of a new anticancer pd(ii) complex, 1,10-phenanthroline-n-butyl dithiocarbamato pd(ii) nitrate, on the heme releasing from human hemoglobin (hb) as well as alterations in the structure and function of hb using different spectroscopic methods of uv-vis, fluorescence and circular dichroism (cd)at two temperatures of 25 and 37 °c. fluorescence data ...

in this paper, lie group structure and lie algebra structure of unit complex 3-sphere     are studied. in order to do this, adjoint representations of unit biquaternions (complexified quaternions) are obtained. also, a correspondence between the elements of     and the special complex unitary matrices    (2) is given by expressing biquaternions as 2-dimensional bicomplex numbers    .  the relat...

in this paper we study isotropic lagrangian submanifolds , in complex space forms . it is shown that they are either totally geodesic or minimal in the complex projective space , if . when , they are either totally geodesic or minimal in . we also give a classification of semi-parallel lagrangian h-umbilical submanifolds.

a structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. the  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-batch r...

a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...

two deoxyglucose (dg) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-d-glucose (ecb-dg) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-d-glucose (dhp-dg), were synthesized and radiolabeled successfully with [99mtc(h2o)3(co)3]+ complex. [99mtc]-ecb-dg and [99mtc]-dhp-dg complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mci of na99mtco4 in 1 ml saline. radi...
