Neurological infections due to rapidly growing mycobacteria (RGM) have rarely been reported. We recently investigated two unrelated immunocompetent patients, one with community-acquired lymphocytic meningitis and the other with cerebral thrombophlebitis. Mycobacterium mucogenicum was isolated in pure culture and detected by PCR sequencing of cerebrospinal fluid samples. Both patients eventually...

We present a numerical method which allows to efficiently calculate quantum transport through phase-coherent scattering structures, so-called “quantum billiards”. Our approach consists of an extension of the commonly used Recursive Green’s Function Method (RGM), which proceeds by a discretization of the scattering geometry on a lattice with nearest-neighbour coupling. We show that the efficienc...

Repulsive guidance molecule (RGM) is a membrane-bound protein originally isolated as a guidance molecule for retinal axons. Three RGM isoforms (RGMa-RGMc) exist in vertebrates. We showed previously that RGMa is a cell-survival factor in the neuroepithelium of chick embryos that suppresses the proapoptotic activity of its receptor neogenin. In the present study, we performed gain- and loss-of-fu...

Antibiotic susceptibility pattern of rapidlygrowing Mycobacteria R. Gayathri, K. Lily Therese, P. Deepa, S. Mangaiand H.N. Madhavan. J Postgrad Med 2010; 50: 76-8. The rapidly growing mycobacteria (RGM) causing human infections primarily consist of the Mycobacterium fortuitum group, Mycobacterium abscessus and Mycobacterium chelonae. The antibiotic susceptibility testing is importan...

This research was initiated to characterize atmospheric deposition of reactive gaseous mercury (RGM), particulate mercury (HgP; <2.5 microm), and gaseous elemental mercury (Hg0) in the arid lands of south central New Mexico. Two methods were field-tested to estimate dry deposition of three mercury species. A manual speciation sampling train consisting of a KCl-coated denuder, 2.5 microm quartz ...

BackgroundThe natural resistance of rapidly growing mycobacteria (RGM) to multiple antibiotics renders the treatment infections caused less successful. The objective this study was evaluate in vitro susceptibilities four oxazolidinones against different RGM species.MethodsThe microplate alamarBlue assay performed identify minimum inhibitory concentrations (MICs) – delpazolid, sutezolid, tedizol...

Sir, Mycobacterium abscessus, a rapidly growing mycobac-terium (RGM), is an important environmental pathogen that can cause a broad spectrum of diseases. Foreign body-associated RGM infections are now receiving increasing emphasis because of the increased use of in-dwelling medical devices. Gastrostomy tube placement is a well-established and tolerated method to achieve feeding access in patien...

The goal of the research presented here is to understand better the factors controlling the remotely sensed signal returned in the solar wavelengths from Chihuahuan Desert grass-shrub transition canopy-soil complexes. The specific objectives were twofold: to evaluate the importance of the different elements (overstory, understory, soil) in the bi-directional reflectance distribution function (B...
