Acute Respiratory Distress Syndrome (ARDS) is characterized by lung injury and damage to the alveolar type II cells. This study sought determine if endogenous surfactant altered in ARDS. Bronchoalveolar lavage was performed patients at-risk develop ARDS (AR, n = 20), with (A, 66) normal subjects (N, 29). The crude pellet analyzed for total phospholipids (PL), individual phospholipids, SP-A, SP-B, minimum surface tension (STmin). PL decreased both AR A (3.48 +/- 0.61 2.47 0.40 mumol/ml,...
Lung surfactant is deficient in patients with acute respiratory distress syndrome (ARDS). We performed a randomized, prospective, controlled, open-label clinical study of administration bovine to ARDS obtain preliminary information about its safety and efficacy. Patients received either by endotracheal instillation addition standard therapy or only. Three different groups receiving were studied: up eight doses 50 mg phospholipids/kg, those 100 four phospholipids/kg. Outcome measures included...

Abstract Human DJ‐1 is a cytoprotective protein whose absence causes Parkinson's disease and also associated with other diseases. has an established role as redox‐regulated that defends against oxidative stress mitochondrial dysfunction. Multiple studies have suggested protein/nucleic acid deglycase plays key in the repair of glycation damage caused by methylglyoxal (MG), reactive α‐keto aldehyde formed central metabolism. Contradictory reports suggest glyoxalase but not does play major...
Surface-active phospholipid-containing particles are traditionally considered to be the product of type II pneumocytes. We now demonstrate membrane-bound lamellar cytoplasmic organelles in adult and suckling rat enterocytes that densely reactive with phospholipid-staining reagents. These structures were seen basolateral space, within intercellular junctions, unraveling on lumenal surface, more abundant after fat feeding. Light scrapings intestinal mucosa washings contained these bodies, as...

A complete understanding of enzyme mechanisms requires atomistic details chemical reactions. Quantum-based molecular dynamics simulations (QMD) are a potential source this information, but tradeoffs between accuracy and computational cost have limited their use. Here, we develop reactive QMD approach to investigate isocyanide hydratase (ICH) catalysis. In simulations, analogs ICH active site residues reacted with para-nitrophenol isocyanide, forming thioimidate intermediate. Analysis...

The 5′ flanking region of the Clara cell secretory protein (CCSP) gene contains two cis-acting elements which bind hepatocyte nuclear factor (HNF)-3 alpha and HNF-3 beta in vitro. To determine role these proteins mediating CCSP expression bronchiolar epithelium, chimeric CCSP-reporter constructs containing various regions were co-transfected into H-441 cells with or plasmids. These studies indicate that each transcription factors positively regulates revealed I (-132 to -76) is sufficient...

Pulmonary surfactant replacement has previously been shown to be effective in the human neonatal respiratory distress syndrome. The value of models acute lung injury other than quantitative deficiency states is, however, uncertain. In this study an model using rats with chronic indwelling arterial catheters, injured N-nitroso-N-methylurethane (NNNMU), developed. NNNMU was found produce hypoxia, increased mortality, alveolitis, and alterations pulmonary system. Alterations obtained by...
