Use of NO Donors in Biological Systems
Molecular Biotechnology, 1999Owing to the increased interest in the biological roles of nitric oxide (NO) the use of NO donors is a desired method of delivering NO to the tissues of interest. This article gives an overview of the most commonly used classes of NO donors and their biotransformation to release NO. A major consideration when choosing an NO donor is the preparation and

Autocatalysis in a biological system
Journal of Theoretical Biology, 1971Abstract A biochemical scheme is analyzed in which the synthesis of a precursor is catalyzed by its product. The scheme shows hysteresis in the steady state concentrations of the intermediates only if the outflow from the system is by reaction with a reversible enzyme. The construction of open systems to correspond to an in vivo environment and the

Experimental Design for Biological Systems
SIAM Journal on Control and Optimization, 2012Summary: Many problems in biology are governed by a dynamical system of differential equations with unknown parameters. To have a meaningful representation of the system, these parameters need to be evaluated from observations. Experimentalists face the dilemma between accuracy of the parameters and costs of an experiment.

Complexity and Stability in Biological Systems
International Journal of Bifurcation and Chaos, 2015The hypothesis that a positive correlation exists between the complexity of a biological system, as described by its connectance, and its stability, as measured by its ability to recover from disturbance, derives from the investigations of the physiologists, Bernard and Cannon, and the ecologist Elton.

Examining Nitroxyl in Biological Systems
2008Nitroxyl (HNO) has received significant recent attention due to its remarkable and novel biological activity and pharmacological potential. Unlike most other commonly studied nitrogen oxides, examination of HNO biology is not straightforward because of its unique chemical properties.
