PURPOSE The primary objective of this randomized phase III study was to show significant difference in median time to progression (TTP) in patients with advanced NSCLC treated with single-agent gemcitabine maintenance therapy versus best supportive care following gemcitabine plus cisplatin initial first-line therapy. PATIENTS AND METHODS Chemonaive(More)
BACKGROUND Mechanical ventilation causes ventilator-induced lung injury in animals and humans. Mitogen-activated protein kinases have been implicated in ventilator-induced lung injury though their functional significance remains incomplete. We characterize the role of p38 mitogen-activated protein kinase/mitogen activated protein kinase kinase-3 and(More)
Ventilator-induced lung injury (VILI) is a major cause of morbidity and mortality in intensive care units. The stress-inducible gene product, heme oxygenase-1, and carbon monoxide (CO), a major by-product of heme oxygenase catalysis of heme, have been shown to confer potent antiinflammatory effects in models of tissue and cellular injury. In this study, we(More)
Chronic obstructive pulmonary disease is one of the leading causes of death and morbidity worldwide. Despite intensive investigation, its pathology and pathophysiology are not well understood. The hallmarks of the disease are irreversible airflow limitation and chronic inflammation. Small airway obstruction due to progressive inflammation and fibrosis, and(More)
OBJECTIVE The efficacy of cisplatin-vinorelbine chemotherapy (CT) in NSCLC is well established. In this retrospective data analysis, haematological safety and tolerability, furthermore the effects of cisplatin-vinorelbine combination on patients' quality of life (QoL) are examined by reviewing the clinical data of NSCLC patients in a retrospective manner.(More)
OBJECTIVES There have been few reports on the association of rheumatoid arthritis (RA) with anti-neutrophil cytoplasmic antigen (ANCA)-associated systemic vasculitides. METHODS Here we present four cases of RA overlapping with Wegener's granulomatosis (WG), microscopic polyangiitis (MPA) and Churg-Strauss syndrome (CSS). All these cases had both the(More)
P-glycoprotein (Pgp) is one of the ABC transporters responsible for the multidrug resistance of cancer cells. The conformational changes of Pgp that occur in the presence of substrates/modulators or ATP depletion are accompanied by the up-shift of UIC2 monoclonal antibody (mAb) binding. In the case of cyclosporin A, vinblastine or valinomycin, this up-shift(More)
The major mechanism of removing cyanide from the body is its enzymatic conversion by a sulfurtransferase, e.g. rhodanese, to the less toxic thiocyanate in the presence of a sulfur donor. Earlier results demonstrated that externally administered encapsulated rhodanese significantly enhances the in vivo efficacy of the given sulfur donor. Present studies are(More)
Prophylactic and therapeutic efficacy against organophosphorus (OP) intoxication by pralidoxime (2-PAM) and atropine were studied and compared with sterically stabilized long-circulating liposomes encapsulating recombinant organophosphorus hydrolase (OPH), either alone or in various specific combinations, in paraoxon poisoning. Prophylactic and therapeutic(More)
Present studies have focused on nano-intercalated rhodanese in combination with sulfur donors to prevent cyanide lethality in a prophylactic mice model for future development of an effective cyanide antidotal system. Our approach is based on the idea of converting cyanide to the less toxic thiocyanate before it reaches the target organs by utilizing(More)
