N-Acetylcysteine was given intravenously and as three fast dissolving and one slow-release formulation, on separate occasions, as a single dose of 600 mg to 10 fasting (5 men and 5 women) healthy volunteers. Blood and urine were sampled for the following 12 h. Renal clearance constituted around 30% of total body clearance, which was 0.21 l/h/kg. Volume of(More)
The clinical symptoms of 55 patients with primary fibromyalgia (PF) were studied and compared with 30 patients with rheumatoid arthritis (RA). The PF patients expressed a more intense feeling of illness than did the RA patients. Stiffness occurred just as often in PF as in RA. Trigger points occurred less frequently in RA patients. Muscular fatigue appeared(More)
Mammalian target of rapamycin (mTOR) has been shown to play an important function in cell proliferation, metabolism and tumorigenesis, and proteins that regulate signaling through mTOR are frequently altered in human cancers. In this study we investigated the phosphorylation status of key proteins in the PI3K/AKT/mTOR pathway and the effects of the mTOR(More)
Prostaglandin E(2) (PGE(2)) has been shown to play important roles in several aspects of tumor development and progression. PGE(2) is synthesized from arachidonic acid by cyclooxygenases (COX) and prostaglandin E synthases (PGES) and mediates its biological activity through binding to the four prostanoid receptors EP(1) through EP(4). In this study, we show(More)
Methods for quantitative analysis of total and non-protein-bound 2-mercaptopropionylglycine (2-MPG) in plasma, and total 2-MPG in urine, have been developed. By reduction of urine, plasma or deproteinized plasma samples with tributylphosphine, 2-MPG is liberated from its disulphides, and after clean-up of the sample, 2-MPG is derivatized with(More)
The research on biosynthesis, physiology, pharmacology, regulation and degradation of catecholamines has continuously increased for more than 50 years. This is not unexpected because of the fact that catecholamines are involved in so many life processes such as nerve conduction, blood circulation and hormone regulations in health and disease. This demands(More)
The clinical utility of detecting minimal residual disease (MRD) in children with neuroblastoma (NB) by quantitative reverse transcriptase polymerase chain reaction (QRT-PCR) is not clear. This in part reflects the lack of uniform methodology for analysis and reporting. Reference laboratories across Europe have therefore established standard operating(More)
Cadmium induced renal effects were examined in 60 workers (58 men, 2 women) previously exposed to cadmium. Tubular damage in the form of beta 2-microglobulinuria was found in 40%, and urinary albumin and orosomucoid increased significantly with increasing urinary cadmium and increasing relative clearance of beta 2-microglobulin. It is suggested that(More)
The cyanide metabolite 2-aminothiazoline-4-carboxylic acid (ATC) was converted to N-carbamylcysteine and analyzed by high-performance liquid chromatography (HPLC) and fluorometric detection. ATC was first separated from interfering substances by passing through the cation exchanger AG 50W-X8. Interfering disulfides were converted to thiols by reduction of(More)
Several transcripts have been claimed to be clinically valuable for detecting minimal disease in neuroblastoma, but they have not been prospectively compared in a standardized manner. Tyrosine hydroxylase (TH), dopa decarboxylase (DDC) and GD2 synthase (GD2S) mRNAs were analyzed in 554 blood (PB) and bone marrow (BM) samples from 58 children with(More)
