Nonsense mutations promote premature translational termination and cause anywhere from 5-70% of the individual cases of most inherited diseases. Studies on nonsense-mediated cystic fibrosis have indicated that boosting specific protein synthesis from <1% to as little as 5% of normal levels may greatly reduce the severity or eliminate the principal(More)
Indinavir sulfate is a human immunodeficiency virus type 1 (HIV-1) protease inhibitor indicated for treatment of HIV infection and AIDS in adults. The purpose of this report is to summarize single-dose studies which characterized the pharmacokinetics of the drug and the effect of food in healthy volunteers. Indinavir concentrations in plasma and urine were(More)
To characterize steady-state indinavir pharmacokinetics in cerebrospinal fluid and plasma, 8 adults infected with human immunodeficiency virus underwent intensive cerebrospinal fluid sampling while receiving indinavir (800 mg every 8 hours) plus nucleoside reverse transcriptase inhibitors. Nine and 11 serial cerebrospinal fluid and plasma samples,(More)
Nonsense (premature stop codon) mutations are causative in 5% to 15% of patients with monogenetic inherited disorders. PTC124, a 284-Dalton 1,2,4-oxadiazole, promotes ribosomal readthrough of premature stop codons in mRNA and offers therapeutic potential for multiple genetic diseases. The authors conducted 2 phase I studies of PTC124 in 62 healthy adult(More)
Indinavir follows nonlinear pharmacokinetics upon oral administration at clinical doses. A study employing the stable isotope administration technique in a three-treatment design was conducted to identify the source of the nonlinearity and to determine the dose-dependency of systemic bioavailability. In treatment A, 400 mg of unlabeled indinavir (D0) was(More)
A variety of cancer cells overexpress transforming growth factor alpha (TGF alpha), a mitogenic peptide. A cDNA sequence coding for the full-length human TGF alpha precursor protein was subcloned into a retroviral expression vector and introduced into clone 7 NIH 3T3 cells, which have low numbers of endogenous epidermal growth factor receptors (EGFRs). The(More)
A cDNA sequence coding for the full-length human transforming growth factor alpha (TGF alpha) precursor protein was introduced into and transcribed in cultured human keratinocytes, using a high-titer, high-expression, murine amphotropic retrovirus. Keratinocytes were shown capable of post-translationally modifying the TGF alpha primary translation product,(More)
STUDY DESIGN Two replicate, 4-week, randomized, double-blind, placebo-controlled, trials of rofecoxib 25 and 50 mg versus placebo for chronic low back pain. OBJECTIVES To determine the efficacy and safety of two doses of rofecoxib compared to placebo in the treatment of chronic low back pain. SUMMARY OF BACKGROUND DATA Although nonsteroidal(More)
BACKGROUND Indinavir, an inhibitor of the human immunodeficiency virus type 1 (HIV-1) protease, is approved for the treatment of HIV infection in adults when antiretroviral therapy is indicated. We evaluated the safety and pharmacokinetic profile of the indinavir free-base liquid suspension and the sulfate salt dry-filled capsules in HIV-infected children,(More)
