The Accreditation Council for Graduate Medical Education Outcome Project has shifted the focus of residents' education to competency-based outcomes learning. challenge meaningful assessment learner competence stimulated interest in Dreyfus and Model, a framework assessing skill acquisition that describes developmental stages beginning with novice progressing through advanced beginner, competent, proficient, expert, master. Many educators have adopted this model, but no consensus about its...
SP 28-36, a major protein of pulmonary surfactant, has striking amino acid sequence homology with soluble mannose-binding proteins isolated from rat liver and contains residues common to the carbohydrate-binding domains other mammalian lectins. We have used carbohydrate-affinity chromatography investigate properties 28-36 canine human (alveolar proteinosis patients) lung lavage. binds immobilized D-mannose, L-fucose, D-galactose, D-glucose.

The pulmonary surfactant proteins SP-B (8,000 D) and SP-C (4,000 accelerate surface film formation by phospholipids. We used cDNA probes to examine regulation of these in human fetal lung. mRNAs were detectable at 13 wk gestation increased approximately 50% (SP-B) 15% (SP-C) adult levels 24 wk. detected only lung 11 dog tissues examined. When was cultured as explants without hormones, mRNA decreased. Exposure for 48 h glucocorticoids, but not other steroids, both (approximately 4-fold)...
The apoproteins of pulmonary surfactant (PSAP) are thought to be critical for normal function. They bind phospholipids and enhance their ability form surface films in vitro. These acidic glycoproteins have monomeric molecular weights 36,000, 32,000, 28,000 (PSAP-36, -32, -28). Each member this family proteins has a similar amino acid composition differences electrophoretic mobility due part glycosylation. We derived the full sequence PSAP-32 from nucleotide PSAP cDNA. A cDNA library was...

Pulmonary surfactant stabilizes lung alveoli, preventing respiratory failure and hyaline membrane disease in premature infants. In addition to lipids, contains apoproteins that are thought be critical for normal function. We have examined the ontogeny regulation of major surfactant-associated protein molecular mass 28-36 kDa (SP 28-36) human fetal lung. SP was not detected tissue from second trimester abortuses by either immunoblot analysis or enzyme-linked immunosorbent assay (less than...

Pulmonary surface active material (SAM), purified from canine lung lavage fluids, is a phospholipid-rich lipoprotein with potent immunosuppressive activity. Experiments were performed to identify those components of SAM that responsible for this effect. Results indicated the lipid, and not protein, fraction was immunosuppressive. Two phospholipids, phosphatidylglycerol phosphatidylcholine, identified as predominant SAM-lipid fraction. lymphocyte proliferation in response mitogenic or...
