Clinical studies were performed to examine the oral bioavailability of alendronate (4-amino-1-hydroxy-butylidene-1,1-bisphosphonate monosodium). All studies, with the exception of one performed in men, involved postmenopausal women. Short-term (24 to 36 hours) urinary recovery of alendronate after an intravenous dose of 125 to 250 micrograms averaged about(More)
Myostatin is a secreted protein that normally functions as a negative regulator of muscle growth. Agents capable of blocking the myostatin signaling pathway could have important applications for treating human muscle degenerative diseases as well as for enhancing livestock production. Here we describe a potent myostatin inhibitor, a soluble form of the(More)
Alendronate (ALN) is an aminobisphosphonate employed as an antiresorptive agent in the treatment of osteoporosis. The present study was carried out to determine dose-response relationships, particularly the effects of relatively low doses of ALN, on bone mineral density (BMD), biochemical indexes of bone and mineral metabolism, and bone histology, with(More)
BACKGROUND In comparing aspirin, nonselective nonsteroidal antiinflammatory agents (NSAIDs), and cyclooxygenase (COX)-2 inhibitors, variation in platelet inhibitory effects exists that may be associated with differential risks of cardiovascular (CV) thrombotic events. Among the randomized, controlled trials with the COX-2 inhibitor rofecoxib, one study(More)
Conventional nonsteroidal anti-inflammatory drugs inhibit both cyclooxygenase (Cox) isoforms (Cox-1 and Cox-2) and may be associated with nephrotoxicity. The present study was undertaken to assess the renal effects of the specific Cox-2 inhibitor, MK-966. Healthy older adults (n = 36) were admitted to a clinical research unit, placed on a fixed sodium(More)
BACKGROUND The localization of substance P in brain-stem regions associated with vomiting, and the results of studies in ferrets, led us to postulate that a neurokinin-1-receptor antagonist would be an antiemetic in patients receiving anticancer chemotherapy. METHODS In a multicenter, double-blind, placebo-controlled trial involving 159 patients who had(More)
Purpose. The safety, tolerability, and pharmacokinetics of intravenous (i.v.) montelukast sodium (Singulair™, MK-0476), and the oral bioavailability of montelukast sodium in healthy males and healthy females were studied. Methods. This was a two-part study. Part I was a four-period study in males of rising i.v. doses of montelukast sodium (3, 9, and 18 mg)(More)
Biochemical markers of bone turnover are finding increased application in the investigation and management of skeletal diseases such as osteoporosis. The present study assessed for the first time the diurnal variation of serum type I collagen cross-linked N-telopeptides (NTx), a new serum-based marker of bone resorption, and the effect of antiresorptive(More)
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease of motor neurons (MNs) that causes paralysis. Some forms of ALS are inherited, caused by mutations in the superoxide dismutase-1 (SOD1) gene. The mechanisms of human mutant SOD1 (mSOD1) toxicity to MNs are unresolved. Mitochondria in MNs might be key sites for ALS pathogenesis, but(More)
BACKGROUND Recent studies have suggested that antiemetic therapy with a triple combination of the neurokinin-1 receptor antagonist MK-869, a serotonin (5-HT(3)) antagonist, and dexamethasone provides enhanced control of cisplatin-induced emesis compared with standard therapy regimens. The authors compared the antiemetic activity of a dual combination of(More)
