    Description / Table of Contents: Verschiedene polyfunktionelle Allylverbindungen, die 4-Oxycarbonylphthalimid-Grup-pen enthielten, wurden dargestellt, darunter N-Allyl-4-phthalimidcarbonsäure-allylester (3), die N,N′-alkylenbis(4-phthalimidcarbonsäure)-diallylester 8a-c und die Alkylenbis(N-allyl-4-phthalimidcarboxylate) 9a-e und 11.Diese Verbindungen wurden durch Erhitzen mit Dicumylperoxid oder Benzoylperoxid zu vernetzten Harzen polymerisiert, deren thermische Stabilität zunächst durch thermogravimetrische Analyse (TG) untersucht wurde. Die aus 9e und 11 hergestellten Harze zeigten unter Stickstoff bis 390 bzw. 360°C keinen Gewichtsverlust.
    Notes: Various polyfunctional allyl compounds containing 4-oxycarbonylphthalimido units were prepared including allyl N-allyl-4-phthalimidecarboxylate (3), diallyl N-N′-alky-lenebis(4-phthalimidecarboxylates) 8a-c and alkylenebis(N-allyl-4-phthalimidecarboxylates) 9a-e and 11.These compounds were polymerized by heating them in the presence of dicumyl peroxide or benzoyl peroxide to afford network resins. The thermal stability of these resins was preliminarily investigated using thermogravimetric analysis (TG). The resins from 9e and 11 had essentially no weight loss up to 390 and 360°C, respectively, in nitrogen.

    Photocrosslinkable polyesters with conjugated double bonds: Reciprocity effect in laser recording (1986)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Notes: The reciprocity effect under intense illumination was studied with photocrosslinkable polyesters of p-phenylenebis(α-cyanobutadiene carboxylic acid) (I), m-phenylenebis(α-cyanobutadiene carboxylic acid) (II), and p-phenylenebis(acrylic acid) (III), with an argon ion laser as a light source. The reciprocal sensitivities of I, II, and III were 5.0, 1800, and 〉 105 mJ/cm2, respectively. II and III required sensitization to enhance their sensitivities to a level at which reciprocity effects could be measured. I obeyed the reciprocity law over a wide range of exposure times from seconds to microseconds. Both II′, a copolyester of II, and III showed a dramatic decrease of sensitivity in high-intensity/short-time exposure when sensitized by 9,10-phenanthraquinone and pyrylium salts.

    Conformational studies of optically active poly(oxyisobutylidenecarbonyl) [poly(L-α-hydroxyisovaleric acid)] and its oligomers (1973)

    Description / Table of Contents: Die ORD- und CD-Kurven von Poly(oxyisobutylidencarbonyl) wurden aufgenommen und mit denen der Oligomeren (III) verglichen. Eine zweitermige DRUDE-Gleichung wurde angewandt, um die ORD-Kurven zu beschreiben, wobei den λ0- und λ1-Werten die n-π* bzw. π-π* Übergänge zugeordnet wurden. Da keine drastischen Unterschiede zwischen den ORD-Kurven des Polymeren und der Oligomeren in Chloroform feststellbar waren, wird geschlossen, daß die Polymeren in diesem Lösungsmittel keine bevorzugte Konformation annehmen. Andererseits zeigen in Dioxan und Acetonitril die λ1-Werte der Polymeren Rotverschiebungen gegenüber den λ1-Werten der Oligomeren.
    Notes: Optical rotatory dispersion (ORD) and circular dichroism (CD) of poly(oxyisobutylidenecarbonyl) (II) were investigated and compared with those of its optically active oligomers (III). The two-term DRUDE equation was applied to analyze the ORD curves using n-π*- and π-π*-transition bands as the critical wavelengths, λ0 and λ1, respectively. No drastic difference in ORD curves between the polymer and oligomers was detected in chloroform, which suggests that the polymer has no special conformation. On the other hand, in dioxane and acetonitrile λ1 of the polymer II shows a red shift in comparison with that of its oligomers.

    In situ detection of insulin-like growth factor II (IGF2) and H19 gene expression in hepatocellular carcinoma (1998)

    Notes: Abstract To assess the relationship between insulin-like growth factor II (IGF2) and H19 gene expression at the cellular level, we have examined the distribution of IGF2 and H19 mRNA by means of in situ hybridization in hepatic malignancies consisting of hepatocellular carcinoma (HCC), cholangiocellular carcinoma (CCC), and metastatic liver cancer (MLC). In HCC, 15 of 27 tumors (56%) and 11 of 27 tumors (41%) demonstrated increased IGF2 and H19 gene expression, respectively. Of 16 HCCs with increased expression of either IGF2 or H19, 10 tumors coexpressed both transcripts at comparable levels. Moreover, the spatiotemporal distribution and the cellular localization of the two gene transcripts were almost identical, suggesting the presence of a reciprocal relation between IGF2 and H19. In addition, 5 HCCs showed increased IGF2 expression without concomitant H19 expression, whereas 1 HCC showed increased H19 expression without IGF2 transcripts. However, 11 HCCs showed no IGF2 or H19 expression. On the other hand, neither IGF2 transcripts nor H19 transcripts were detected in 2 CCCs or 10 MLCs studied. The data suggest that IGF2 and/or H19 gene expression may be characteristic of some HCCs.

Die Benzylester erhielt man durch schrittweisen Aufbau, der von der Umsetzung des Dichloressigsäureesters des Oxypivalinsäurechlorids mit der Hydroxylgruppe eines Oligooxypivalinsäureesters ausging. Die Abspaltung der Dichloracetylgruppe erfolgte durch milde alkalische Hydrolyse. Die Schmelzpunkte, die IR- und die NMR-Spektren dieser Oligomeren wurden bestimmt.
    Notes: Linear oligohydroxypivalates terminated with a hydroxy and a carboxy group \documentclass{article}\pagestyle{empty}\begin{document}$${\rm H\hbox{---} [\hbox{---} OCH}_{2} {\rm C(\rm CH}_{3} )_3 {\rm CO\hbox{---} ]}_{{\rm n}}\hbox{---} {\rm OH \ (n = 1 - 6),}$$\end{document} were synthesized by the catalytic hydrogenolysis of the corresponding oligohydroxypivalate benzyl esters. The oligohydroxypivalate benzyl esters, in turn, were prepared by a stepwise method which involved the condensation of dichloroacetoxypivaloyl chloride with a preceding hydroxy terminated oligohydroxypivalate followed by removal of the dichloroacetyl group by mild alkaline hydrolysis. Melting points, infrared spectra and nuclear magnetic resonance spectra of the oligomers were studied.
