| huntington's disease--growth of fibroblast cultures in lipid-deficient medium: a preliminary report. | when skin fibroblast cultures derived from subjects with huntington's disease (hd) were grown in medium supplemented with lipid-deficient serum (lds), growth rates were less than those of control cultures. the mean percentage increase in generation times for nine control cultures incurred by using lds rather than fetal calf serum (fcs) was 8.0%. four cultures from 2 patients with hd failed to grow in lds but grew well in medium supplemented with fcs. in nine other cultures derived from 7 patient ... | 2003 | 152597 |
| study of the kinetics of conversion of maternal plasma dehydroisoandrosterone sulfate to 16 alpha-hydroxydehydroisoandrosterone sulfate, estradiol, and estriol. | the transfer constants of conversion of maternal plasma dehydroisoandrosterone sulfate to estradiol ([rho]ds-e2bu) and to 16alphaoh-dehydroisoandrosterone sulfate ([rho]ds-160hds bu) and of maternal plasma 16alphaoh-dehydroisoandrosterone sulfate to estriol ([rho]160hds-e3 bu) were measured in women late in pregnancy. the mean [rho]160hds-e3 bu, 0.17, was considerably less than the mean [rho]ds-e2 bu, 0.29. however, the extent of 16alpha-hydroxylation of maternal plasma dehydroisoandrosterone su ... | 2003 | 152062 |
| phage typing of nontypable isolates of staphylococcus aureus using the new phages 94, 95, and 96 and the heat-shock treatment. | of 2,144 isolates of staphylococcus aureus (from human beings in new york state) received in the authors' laboratory during 1975, 992 (46.,%) were nontypable with the use of the international basic set of bacteriophages. these 2,144 isolates were retested with the use of the recently added phages 94, 95, and 96. nearly 60% of the isolates were lysed with one or more of these three phages, including 64% of those previously nontypable, thus reducing the percentage of nontypables to 16.5%. one hund ... | 1978 | 152059 |

| comparative clinical pharmacokinetics of tubocurarine, gallamine, alcuronium and pancuronium. | data about plasma concentration, renal and biliary elimination of tubocurarine, gallamine, alcuronium and pancuronium are taken from the literature for synoptical pharmacokinetic analysis. all plasma concentration curves can be described by triexponential functions according to an open three-compartment pharmacokinetic model in line, the elements of which are an application and measuring compartment, a pharmacologically specific compartment and a non-specific one. the corresponding results for a ... | 2002 | 150804 |
| hypersensitivity reactions to food colours with special reference to the natural colour annatto extract (butter colour). | it is well known that synthetic food colours especially some azo dyes can provoke hypersensitivity reactions such as urticaria, angioneurotic oedema, and astma (michaëlsson and juhlin, 1973, granholt and thune, 1975). natural food colours are scarcely investigated with respect to potential allergic properties. annatto extract, a commonly used food colour in edible fats e.g. butter, has been tested in patients. among 61 consecutive patients suffereing from chornic urticaria and/or angioneurotic o ... | 2003 | 150265 |
