Acknowledgments A large part of the preliminary and not inconsiderable work of making the ftp archives of the "subversive discussion" was done CONTENTS INTRODUCTION I.Overture: The Subversive Proposal II.The Discussion Begins The first response to Harnad's proposal was swift, practical: an offer by a systems administrator to house a comprehensive scientific(More)
To evaluate potential direct effects of glucocorticoids on the aqueous outflow pathway, the cellular binding of steroids to cultured human trabecular cells was examined. After incubation of cells with 5 to 40 nM [3H]dexamethasone, specific binding (i.e., binding that could be blocked by an excess of nonlabeled steroid) was detected by measuring the total(More)
PURPOSE Nuclear factor-κB (NF-κB), a key regulator of immune and inflammatory responses, plays important roles in diabetes-induced microvascular complications including diabetic retinopathy (DR). Thrombin activates NF-κB through protease-activated receptor (PAR)-1, a member of the G-protein-coupled receptor (GPCR) superfamily, and contributes to DR. The(More)
publications committee, or a journal editorial board, you may have paid only passing attention to the debate over public access to scientifi c research, which has been swirling through these communities ever since science journals started publishing online 15 years ago. That is about to change. Last week, the U.S. House Science and Technology Committee's(More)
Isopilocarpine coexists with pilocarpine in nature, and it is present in varying degrees in commercial pilocarpine preparations. Using muscarinic cholinergic receptors from bovine ciliary muscle tissue, we measured the relative binding affinity of isopilocarpine and pilocarpine. The binding affinity of isopilocarpine was approximately one-tenth that of(More)
Excessive mechanical ventilation exerts pathologic mechanical strain on lung vascular endothelium and promotes endothelial cell (EC) inflammatory activation; however, the specific mechanisms underlying EC inflammatory response caused by mechanical ventilation related cyclic stretch (CS) remain unclear. This study investigated the effects of chronic exposure(More)
The diagnosis of ocular sarcoid is presumptive in the absence of systemic disease. The association of elevated serum angiotensin-converting enzyme (ACE) levels with active systemic sarcoid has been well described. With a sensitive fluorimetric assay for ACE, we found that five of ten chronic granulomatous uveitis patients without systemic sarcoid had(More)
