Sir, Bartonella henselae are fastidious, facultative intracellular bacilli that can cause bacteraemia, endocarditis, cat-scratch disease in immunocompetent patients, and bacillary angiomatosis and peliosis hepatitis in immunocompromised patients. There are a limited number of studies that have addressed the antibiotic treatment of cats infected with B. henselae. Azithromycin, a macrolide compou...

Abstract Background Pseudomonas aeruginosa is a common opportunistic pathogenic bacterium with the ability to develop strong communication pathway by quorum sensing system and different virulent factors. Among various important secretions of P. rhamnolipid biological detergent, believed be involved in development biofilm intercellular communication. It readily dissolves lung surfactants that ar...

Rappaport D., A convex hull algorithm for discs, and applications, Computational Geometry: Theory and Applications 1 (1992) 171-187. We show that the convex hull of a set of discs can be determined in @(n log n) time. The algorithm is straightforward and simple to implement. We then show that the convex hull can be used to efficiently solve various problems for a set of discs. This includes O(n...

We present the results of a study of propagating warp or bending waves in accretion discs. Three dimensional hydrodynamic simulations were performed using SPH, and the results are compared with calculations based on the linear theory of warped discs. We examine the response of a gaseous disc to an initially imposed warping disturbance under a variety of physical conditions. We consider primaril...

Platelet‑rich plasma (PRP) is a promising strategy for intervertebral disc degeneration (IDD). However, the short half‑life of growth factors released from PRP cannot continuously stimulate the degenerated discs. Thus, the present study hypothesized that the combined use of PRP and bone marrow‑derived mesenchymal stem cells (BMSCs) may repair the early degenerated discs in the long term for the...

In FOCS 2002, Even et al. showed that any set of n discs in the plane can be Conflict-Free colored with a total of at most O(log n) colors. That is, it can be colored with O(log n) colors such that for any (covered) point p there is some disc whose color is distinct from all other colors of discs containing p. They also showed that this bound is asymptotically tight. In this paper we prove the ...

Sensitivity discs containing 1 and 2 mg meso-erythritol were found to give comparable results to the use of meso-erythritol incorporated into growth medium at 1 and 2 mg/ml. The discs proved easy and efficient when used in a disc ring together with benzyl penicillin and streptomycin sulphate discs.

The noncarbonaceous Ediacaran discs of variable morphologies from the Jodhpur Sandstone Formation of the Marwar Supergroup, western Rajasthan, suggest different biologic affinities of plant and animal kingdom. These discs are commonly preserved on the bedding surfaces of siliciclastic sandstone and shale in strong positive relief and appear to possess a flexible to rigid body. Discs assignable ...
