Although interactions between superoxide (O(2)(.-)) and nitric oxide underlie many physiologic and pathophysiologic processes, regulation of this crosstalk at the enzymatic level is poorly understood. Here, we demonstrate that xanthine oxidoreductase (XOR), a prototypic superoxide O(2)(.-) -producing enzyme, and neuronal nitric oxide synthase (NOS1) coimmunoprecipitate and colocalize in the sar...

-The notion of Carry Value Transformation (CVT) is a model of Discrete Deterministic Dynamical System. In this paper, we have studied some interesting properties of CVT and proved that (1) the addition of any two non-negative integers is same as the sum of their CVT and XOR values. (2) While performing the repeated addition of CVT and XOR of two non-negative integers “a” and “b” (where a ≥ b), ...

XOR & AND gates are most important basic building blocks of any VLSI applications. These gates can be implemented in different architectures by using different circuit designs techniques. This paper evaluates and compares the performance of various design techniques of XOR-AND gates. The performances of these techniques have been evaluated by Tanner Tools V13 using the 90nm CMOS technology. In ...

In this report, we describe the synthesis and characterization of 1,3-bis(hexyloxy)propan-2-yl nitrate (NDHP), a novel organic mono nitrate. Using purified xanthine oxidoreductase (XOR), chemiluminescence and electron paramagnetic resonance (EPR) spectroscopy, we found that XOR catalyzes nitric oxide (NO) generation from NDHP under anaerobic conditions, and that thiols are not involved or requi...

Febuxostat, a drug recently approved in the US, European Union and Japan for treatment of gout, inhibits xanthine oxidoreductase (XOR)-mediated generation of uric acid during purine catabolism. It inhibits bovine milk XOR with a K(i) in the picomolar-order, but we found that it is a much weaker inhibitor of Rhodobacter capsulatus XOR, even though the substrate-binding pockets of mammalian and b...

We discuss novel functional MEMS/NEMS structures that enable implementation of universal logic gates such as XOR, AND, NAND, NOT, etc. in a single device instead of using 6-14 individual switches used in CMOS. By reducing the number of devices, our approach improves yield, reproducibility and speed and simplifies implementation of circuits such as adders and multiplexers. We show the feasibilit...

Küsters and Truderung recently proposed an automatic verification method for security protocols with exclusive or (XOR). Their method reduces protocols with XOR to their XOR-free equivalents, enabling efficient verification by tools such as ProVerif. Although the proposed method works efficiently for verifying secrecy, verification of authentication properties is inefficient and sometimes impos...
