Background and Objective: Burn wound infections caused by Pseudomonas aeruginosa exhibiting β-lactam antibiotic resistance are one of the greatest challenges of antimicrobial treatment. In this context, P. aeruginosa strains harboring resistance mechanisms, such as production of extended-spectrum beta-lactamases have the highest clinical impact no the management of burn wound infections. The ai...

Mycobacterium tuberculosis (M. tb) must cause lung disease to spread. Matrix metalloproteinases (MMPs) degrade the extracellular matrix and are implicated in tuberculosis-driven tissue destruction. We investigated signaling pathways regulating macrophage MMP-1 and -7 in human pulmonary tuberculosis and examine the hypothesis that the antimycobacterial drug p-aminosalicylic acid acts by inhibiti...

BACKGROUND AND OBJECTIVES Simvastatin's properties are suggestive of a potential pathophysiologic role in pulmonary hypertension. The objectives of this study were to investigate changes of pulmonary pathology and gene expressions, including endothelin (ET)-1, endothelin receptor A (ERA), inducible nitric oxide synthase (NOS2), endothelial nitric oxide synthase (NOS3), matrix metalloproteinase ...

BACKGROUND Pulmonary tuberculosis is associated with caseating necrosis, parenchymal lung destruction, and cavity formation. It was hypothesised that tuberculous lung destruction is mediated, at least in part, by the participation of matrix metalloproteinases released by mononuclear phagocytes. METHODS Cells of the myelomonocytic leukaemia cell line THP-1 were incubated with lipoarabinomannan...
