Lipid peroxides in tissues were fluorometrically determined using 1,3-diphenyl-2-thiobarbituric acid (DPTBA) as a fluorogenic reagent, and the results were compared with those obtained by the DPTBA-visible method, thiobarbituric acid (TBA)-fluorescence method, or TBA-visible method. The optimum conditions for determining lipid peroxides were analyzed by using brain homogenate. The optimum pH fo...

Lead-induced hypertension has previously been shown to be closely associated with an increase in reactive oxygen species in low lead (100 ppm)-treated rats. The present study has attempted to define the specific moiety involved by noting the blood pressure (BP), reactive oxygen species (MDA-TBA), hydroxyl radical, and nitrotyrosine responses to infusion of the reactive oxygen species scavenger ...

The solution structure of a new modified thrombin binding aptamer (TBA) containing a 5'-5' inversion of polarity site, namely d(3'GGT5'-5'TGGTGTGGTTGG3'), is reported. NMR and CD spectroscopy, as well as molecular dynamic and mechanic calculations, have been used to characterize the 3D structure. The modified oligonucleotide is characterized by a chair-like structure consisting of two G-tetrads...

We investigate the thermodynamic Bethe ansatz (TBA) equations for a system of particles which dynamically interacts via the scattering matrix of affine Toda field theory and whose statistical interaction is of a general Haldane type. Up to the first leading order, we provide general approximated analytical expressions for the solutions of these equations from which we derive general formulae fo...

The solution structure of a new modified thrombin binding aptamer (TBA) containing a 50–50 inversion of polarity site, namely d( 0 GGT 0 0 TGGTGTGGTTGG0), is reported. NMR and CD spectroscopy, as well as molecular dynamic and mechanic calculations, have been used to characterize the 3D structure. The modified oligonucleotide is characterized by a chair-like structure consisting of two G-tetrads...

Logical policy-based access control models are greatly expressive and thus provide the flexibility for administrators to represent a wide variety of authorization policies. Extensional access control models, on the other hand, utilize simple data structures to better enable a less trained and non-administrative workforce to participate in the day-to-day operations of the system. In this paper, ...

The traditional thermodynamic Bethe ansatz (TBA) equations for the XXZ model at |∆| ≥ 1 are derived within the quantum transfer matrix (QTM) method. This provides further evidence of the equivalence of both methods. Most importantly, we derive an integral equation for the free energy formulated for just one unknown function. This integral equation is different in physical and mathematical aspec...
