The cloned DNA fragment of the cytochrome P-450b/e gene containing the upstream region from position -179 through part of the first exon is faithfully transcribed in freeze-thawed rat liver nuclei. Phenobarbitone treatment of the animal strikingly increases this transcription, and the increase is blocked by cycloheximide (protein synthesis inhibitor) or CoCl2 (heme biosynthetic inhibitor) treatment of animals. This picture correlates very well with the reported cytochrome P-450b/e mRNA levels in vivo and run-on transcription rates in vitro under these conditions. The upstream region (from position -179) was assessed for protein binding with nuclear extracts by nitrocellulose filter binding, gel retardation, DNase I treatment ("footprinting"), and Western blot analysis. Phenobarbitone treatment dramatically increases protein binding to the upstream region, an increase once again blocked by cycloheximide or CoCl2 treatments. Addition of heme in vitro to heme-deficient nuclei and nuclear extracts restores the induced levels of transcription and protein binding to the upstream fragment, respectively. Thus, drug-mediated synthesis and heme-modulated binding of a transcription factor(s) appear involved in the transcriptional activation of the cytochrome P-450b/e genes, and an 85-kDa protein may be a major factor in this regard.

Sodium p-nitrophenolate dihydrate single crystals possess excellent nonlinear optical properties such that they can be used for optical second-harmonic generation. It belongs to the orthorhombic system with the space group Ima2. Slow evaporation or slow cooling techniques can be used to grow good optical quality single crystals from supersaturated solution. All the nine elastic constants of this crystal have been measured using an ultrasonic technique. Samples for measurements have been cut along desired crystallographic axes and the pulse echo overlap technique has been used to measure longitudinal and shear ultrasonic wave velocities along appropriate symmetry directions in the crystal. The McSkimin Delta t criterion has been applied to determine the round trip travel time accurately, from which the nine elastic constants have been evaluated. Temperature variation of selected elastic constants in a limited range have also been measured and reported.

p-aminobenzoate could be intercalated into the anionic clay, Ni3Zn2(OH)(8)(OAc)(2)center dot 2H(2)O at a high pH (similar to 10). When the pH was reduced to similar to 7 while washing colloidal dispersion due to delamination was observed. The development of partial positive charge on the amine end of the intercalated anion causes repulsion between the layers leading to delamination and colloidal dispersion of monolayers in water. The layers could be restacked from the colloid to form the parent solid either by increasing the pH or by evaporation.

Syftet med denna studie är att genom data-analys triangulation undersÃka socionomstuderandes svar pÃ¥ ett yrkesetiskt dilemma av omsorgsetisk natur. Samplet bestÃ¥r av 32 socionomer i bÃrjan av sina studier som har svarat pÃ¥ ett hypotetiskt dilemma om hur de skulle bemÃta en ung kvinna som ber om rÃ¥d i en mycket svÃ¥r situation. De huvudsakliga teoretiska utgÃ¥ngspunkterna fÃr detta arbete är ECI (Ethic of Care Interview) som utvecklats av Eva Skoe som metod fÃr att undersÃka omsorgsetik, samt Osers och Althofs teori om diskursiva problemlÃsningsmetoder bland professionella. Som grundläggande teorier fÃr all modern forskning om människans moralutveckling, presenteras ocksÃ¥ Carol Gilligans och Lawrence Kohlbergs teorier samt den huvudsakliga kritiken dessa bemÃtt. Carol Gilligan är den som ursprungligen presenterade tanken om att det finns tvÃ¥ olika typer av moraliskt tänkande där omsorgsetik är mer typisk fÃr kvinnor och rättviseetik är mer typisk fÃr män. Den fÃrsta delen av analysen är en innehÃ¥llsanalys där svaren pÃ¥ det yrkesrelaterade dilemmat pÃ¥ olika ECI stadium jämfÃrs med varandra. Poängsättningen i ECI har varit grunden fÃr denna analys. Den andra delen av analysen är en deduktiv teoribunden analys, där jag undersÃkt i fall Osers och Althofs modell om problemlÃsningsstrategier även gÃ¥r att tillämpa pÃ¥ ett yrkesetiskt dilemma. Slutligen tar jag ocksÃ¥ ställning till dessa tvÃ¥ teoriers kompatibilitet. Resultatet visar att eleverna har svarat aningen sämre pÃ¥ det yrkesetiska dilemmat än vad deras allmänna ECI stadium är. Detta kan bero pÃ¥ att de är i bÃrjan av sina studier men ocksÃ¥ pÃ¥ det allmänna klimat som rÃ¥der inom socialbranschen. Teorin om diskursiva problemlÃsningsstrategier gÃ¥r inte heller att tillämpa pÃ¥ detta yrkesetiska dilemma, eftersom den hypotetiska klientens självbestämmanderätt gÃr en diskursiv lÃsning omÃjlig. Till fÃljd av detta har jag skapat en ny modell som baserar sig pÃ¥ 6 kategorier utgÃ¥ende frÃ¥n de faktorer de intervjuade lyfter fram som de viktigaste i den professionellas mÃte med klienten. Eftersom den nya modellen inte är hierarkisk, kan de tvÃ¥ teorierna inte jämfÃras med varandra pÃ¥ sÃ¥ sätt att hÃgre ECI nivÃ¥ skulle innebära en viss typ av problemlÃsningsstrategi.

Alpha-Terpineol (I), a monocyclic monoterpene tertiary alcohol, is widely used in the manufacture of perfumes, cosmetics, soaps and antiseptic agents. It was reported earlier (Horning et al. 1976) that this monoterpene alcohol when administered to humans is hydroxylated to p-menth-l,2,8-triol (II). It is not known whether c~-terpineol also produces other metabolites during its metabolism in the mammalian system and if so, the nature of these metabolites.
