Background: The pathogenesis of Mycobacterium avium complex and Mycobacterium tuberculosis in the respiratory tract is poorly understood, as are the reasons for their differing virulence. We have previously shown that their initial adherence to the mucosa is identical. Methods: The interaction of M avium complex, M tuberculosis, and M smegmatis with human respiratory tissue was investigated in ...

The aim of this study was to examine the specificity of primers designed to detect the insertion element IS901 commonly used in differentiation of Mycobacterium avium complex strains. This study shows that one of these primers non-specifically anneals to a sequence inside insertion element IS900, specific IS of M. avium subsp. paratuberculosis and to another sequence flanking this element. The ...

In this paper, we use resource-bounded dimension theory to investigate polynomial size circuits. We show that for every i ≥ 0, P/poly has ith order scaled p 3 -strong dimension 0. We also show that P/poly i.o. has p 3 -dimension 1/2, p 3 -strong dimension 1. Our results improve previous measure results of Lutz (1992) and dimension results of Hitchcock and Vinodchandran (2004).

there were many occupational toxins for central nervous system and peripheral nervous system such as toxic and heavy metals. the aim of this study was introduction of occupational toxins with neurological effects and inflammatory effects specially. it is a review article. researcher found the important data about the occupational toxins for nervous systems. author searched in related journals, ...

multiple sclerosis (ms) is an inflammatory and autoimmune disease.ms is characterized by blood brain barrier breakdown, inflammation, axonal injury, degeneration of the myelin sheath and etc. a significant association between inflammation and degeneration of neurons is observed in the brain. also active ms lesions always associated with inflammation thus inflammation is a target for treatment o...

The problem of counting unlabelled subtrees of a tree (that is, subtrees that are distinct up to isomorphism) is #P-complete, and hence equivalent in computational difficulty to evaluating the permanent of a 0,1-matrix.
