Retinoids are reported to stimulate apolipoprotein (apo) A-I gene promoter activity (Rottman et al. 1991. Mol. Cell. Biol. 11: 3814-3820) and apoA-I protein secretion by monkey hepatocytes (Kaptein et al. 1993. Arterioscler. Thromb. 13: 1505-1514). In this study we have assessed the effects of retinoids on parameters of apoA-I biosynthesis in human cell(More)
We have previously compared 25-hydroxycholecalciferol levels in the serum of patients with osteoarthrosis and rheumatoid arthritis, finding no significant difference between the circulating levels of this hormone. We have now estimated 1,25-dihydroxycholecalciferol levels on stored sera from the same groups of patients and found no significant difference in(More)
Previous studies from our laboratory have shown that oral administration of stigmastanyl-phosphocholine (Ro 16-6532) reduces plasma cholesterol levels in experimental animals on diets free of added cholesterol. In the present study, effects of Ro 16-6532 and lovastatin on lipoprotein levels and metabolism were investigated in male golden Syrian hamsters. In(More)
It was the aim of this study to i) compare the effects of glucose and other hexoses with that of oleate on secretion of apolipoproteins (apos) A-I and B by HepG2 cells, and ii) document the effect of various metabolic inhibitors on the secretion of these apos in the absence or presence of extra glucose/oleate. i) The addition of 10 mM glucose increased(More)
It has been postulated that hyperparahyroidism is in part responsible for sexual dysfunction in dialyzed patients and that this could improved by 1,25(Oh)2D3. In a single blind study patients on maintenance hemodialysis were treated after a control period with 1,25 (OH)2D3 and with placebo in random order. Sexual performance was assessed with a detailed(More)
Groups of 4-6 Fü-albino rats were examined 24 h after 3 daily doses of 500 mg/kg bw of theobromine administered orally by gavage as well as 1, 2, 4, 6, and 10 weeks after 5 daily doses. Controls received the standard solvent vehicle (SSV) only. A variety of parameters were assessed including body and organ weights, serum clinical chemistry, hematological(More)
Three different procedures have been used for detecting antibodies to Roferon-A (recombinant human interferon alfa-2a, rHuIFN alpha-2a) in the serum of patients who received this interferon as part of ongoing clinical trials: an antiviral neutralization bioassay (ANB), the standard method recommended by the World Health Organization (WHO), and the more(More)
The arotinoid Ro 14-9706, though devoid of any teratogenic potential, was found to reduce dose dependently the survival of pups when their mothers were treated with toxic doses during days 6-15 of gestation. The increased mortality was primarily seen during early lactation. When pups derived from treated mothers were nursed by control foster mothers(More)
