BACKGROUND The repulsive guidance molecule (RGM) proteins, originally discovered for their roles in neuronal development, have been recently identified as co-receptors in the bone morphogenetic protein (BMP) signaling pathway. BMPs are members of the TGFbeta superfamily of signaling cytokines, and serve to regulate many aspects of cellular growth and differentiation. RESULTS Here, we investig...

Rapidly growing mycobacteria (RGM) are environmental organisms capable of causing a wide spectrum of diseases. We identified 116 cancer patients with RGM. Mycobacterium mucogenicum was the leading cause of disease. Removal of the catheter correlated with significant decrease in the bacteremia relapse rate (P = .007). A median duration of 4 weeks of therapy produced a good outcome.

Rapidly growing mycobacteria (RGM) inhabit soil and water but certain strains represent a health risk for human and animals. Both clinical and soil RGM may be under selection pressure for resistance to tetracycline (TET) antibiotics, since tetracyclines are administrated to humans and farm animals, and TET residues enter soil through manuring; however, resistance to TET and the presence of TET-...

Induction of heme oxygenase-1 (HO-1) expression has been associated with cytoprotective and anti-inflammatory actions of lansoprazole, a proton pump inhibitor, but the underlying molecular mechanisms remain largely unresolved. In this study, we investigate the role of transcriptional NF-E2-related factor 2 (Nrf2), its phosphorylation/activation, and oxidation of Kelch-like ECH-associating prote...

abstract: To understand recently established empirical p + α potentials, RGM calculations followed by inversion are made to study contributions of the d + 3 He reaction channels and deuteron distortion effects to the p + α potential. An equivalent study of the d + 3 He potential is also presented. The contributions of exchange non-locality to the absorption are simulated by including an phenome...

Product quality is directly related to how well that product meets the customer’s needs and intents. It is paramount, therefore, to capture customer requirements correctly and succinctly. Unfortunately, most development models tend to avoid, or only vaguely define the process by which requirements are generated. Other models rely on formalistic characterizations that require specialized trainin...

Mycobacterium abscessus is a rapidly growing mycobacterium (RGM) causing serious infections especially among cystic fibrosis patients. Extremely limited therapeutic options against M. abscessus and a rise in infections with this mycobacterium require novel chemotherapies and a better understanding of how the bacterium causes infection. Different from most RGM, M. abscessus can survive inside ma...

We compared the in vitro activity of the glycylcycline tigecycline (formerly GAR-936) with those of tetracycline, doxycycline, and minocycline by broth microdilution against 76 isolates belonging to seven species of rapidly growing mycobacteria (RGM) and 45 isolates belonging to five species of slowly growing nontuberculous mycobacteria (NTM). By using a resistance breakpoint of >4 micro g/ml f...

We compared the radiosensitivity of macrophage (M) colony-forming cell (CFC) in and outside the hemopoietic bone marrow. Murine bone marrow cells (BMC) are stimulated by either macrophage colony-stimulating factor (CSF-1) or murine recombinant granulocyte-macrophage colony-stimulating factor (rGM-CSF) to form M- and granulocyte- macrophage (GM) colonies on soft agarose medium, whereas both peri...
