Mycobacteria are endowed with rich and diverse machinery for the synthesis, utilization, and degradation of cAMP. The actions of cyclic nucleotides are generally mediated by binding of cAMP to conserved and well characterized cyclic nucleotide binding domains or structurally distinct cGMP-specific and -regulated cyclic nucleotide phosphodiesterase, adenylyl(More)
The sandpile model, introduced in 1987, was the first model to exhibit self-organized critical behavior, that is, the system moved towards its critical point without the need to tune any adjustable external parameter. In this paper, we look at the why these models exhibit such non-intuitive behavior. We also look at some of the phenomenology near the(More)
Antibiotic resistance is concern of today's world. Search for alternative molecules, for treatment and immune stimulation, remains at the forefront. One such group of biomolecules with promise, along the line of immune stimulation or therapy, is host defense peptide (HDP). These molecules, however, are required at a higher dose to be effective which leads(More)
The classical limit problem of quantum mechanics is revisited on the basis of a scheme that enables a quantitative study of the way the quantumclassical agreement emerges while going through the intermediate mass range between the microscopic and the macroscopic domains. As a specific application of such a scheme, we investigate the classical limit of a(More)
A 61-year-old female with past medical history of maculopapular rash reaction to ciprofloxacin and amoxicillin being treated for diverticulitis develops the same rash with administration of piperacillin/tazobactam and aztreonam. A diffuse maculopapular rash developed after the administration of piperacillin. It resolved with discontinuation of the drug and(More)
