[3H]Retinoic acid (RA) and [3H]retinol bind in an unsaturable manner to isolated nuclei from Nulli-SCC1 and PCC4.aza1R embryonal carcinoma (EC) cells. When nuclei are challenged with the same labeled retinoids on their respective binding proteins (CRABP and CRBP), much less binding is observed and the binding is saturable. RA-CRABP does not compete with [3H]retinol-CRBP for binding to specific ...

introduction: prolonged labor can lead to maternal and neonatal complications. the purpose of this study was to investigate the effect of pethidine on the duration of active labor in nulli-parous women. materials and methods: in a randomized clinical 90 nulliparous women with uncomplicated singleton pregnancies at term were randomly assigned into two groups. the first group received 50 mg pethi...

Gene-dosage responses for a group of six wheat endosperm proteins have been investigated by using compensated nulli-tetrasomic lines of cv. Chinese Spring. Practically linear dosage responses have been observed for all the proteins. However, for two of the proteins (and probably for a third one), the net output of protein, at each dosage of its structural gene, was 30-80% higher when the chromo...

We describe two additive systems of intercellular adhesion in teratocarcinoma stem cells (Nulli cell line). One component is divalent cation-dependent (Ca++ or Mg++) and the other involves a cell surface fucan/mannan-specific lectin, previously identified on stem cells by an erythrocyte rosetting assay. The existence of these two systems is inferred from the observation that reaggregation of st...

Five arotinoids have been compared with all-trans- and 13-cisretinoic acids for their ability to promote differentiation of cells from murine embryonal carcinoma line Nulli-SCC1. Ro-13-7410, which contains a terminal carboxylic acid residue, and Ro-14-9572, the sodium sulfinate derivative, are potent inducers of differentiation. The sodium sulfonate derivative, Ro-14-3899, is somewhat less acti...

Time-courses of the development of freezing tolerance and the expression of a cold-responsive gene wlt10 were monitored during cold acclimation in wheat (Triticum aestivum L.). Bioassay showed that cold acclimation conferred much higher freezing tolerance on a winter cultivar than a spring cultivar. Northern blot analysis showed that the expression of wlt10 encoding a novel wheat member of a ce...

A previously described D genome locus (Pin) that controls sterol esterification in the wheat kernel has been assigned to the short arm of chromosome 7 D by comparison of the steryl ester phenotype of euploid kernels of Triticum aestivum variety Chinese Spring with those of the compensated nulli-tetrasomic lines and the 7 D S ditelosomic. Palmitate is the predominant ester in all but the 7 D nul...
