Retinoids, such as all-trans-retinoic acid, play an essential role in the regulation of airway epithelial cell growth, differentiation, and gene expression. Using cDNA microarray, we identified a clone, DD4, that contains the cDNA of a novel gene, spurt (secretory protein in upper respiratory tracts) that was significantly induced by all-trans-retinoic acid(More)
Previous studies on a cryptococcal culture filtrate (CneF) antigen have shown that the antigen is useful in detecting delayed-type hypersensitivity and that it is specific for Cryptococcus. This study further defined one more parameter of specificity, showing that the CneF antigen does not elicit delayed-type hypersensitivity responses in Cryptococcus(More)
We have established a new method to purify Müllerian inhibiting substance (MIS) with higher purity and recovery over existing procedures. Recombinant human MIS was expressed in Chinese hamster ovary cells and secreted into chemically defined serum-free media. The secreted products were concentrated by either precipitation with ammonium sulfate or(More)
OBJECTIVES To analyze 202 consecutive frontal sinus fracture (FSF) patients treated between 1974 and 2002 at the University of California, Davis. METHODS A retrospective chart review was performed, including all patients with frontal sinus fractures from 1987 to 2002. This and 72 previously reported patients (1974-1986) were analyzed, comparing age,(More)
Eustachian tube dysfunction frequently results in clinical evidence of otitis media with effusion (OME). Surface active substances, surfactants, are hypothesized to play a role in normal eustachian tube function. Recent work in a rodent model has demonstrated improved eustachian tube function with topical application of surfactants to the middle ear. A(More)
OBJECTIVES Granulosa cell tumors (GCTs) comprise 2-5% of ovarian tumors. Serum Müllerian Inhibiting Substance (MIS, also known as anti-Müllerian hormone, or AMH) levels have been validated as a marker of GCT recurrence and progression. There has been little correlation between serum MIS/AMH levels and several clinical parameters in GCTs, including tumor(More)
OBJECTIVE Mandibular alloplastic bone trays have an unacceptably high rate of extrusion. The introduction of resorbable mesh has renewed interest in such trays. This study evaluates the effect of resorbable trays on bone graft healing in a dog model. DESIGN Unilateral, 20-mm mandibular body defects were created in 10 dogs, and repaired with cancellous(More)
