Molecular genetics of 2, 4-dichlorophenoxyacetate (2, 4-D) degradation in pseudomonas cepacia strain 2a
Pseudomonas cepacia strain 2a, which utilises2,4-dichlorophenoxyacetate (2,4-D) as a sole source of carbon and energy, has been shown to contain an 17kbp plasmid, p2,4-D, which has been mapped using BamHI and Asp718. Several mutants of strain 2a unable to grow on 2,4-D were generated by temperature …

Phenyl and pentafluorophenyl substiuted 1, 3-dio-xolan 2, 4-diones
A series of phenyl and pentafluorophenyl substituted 1, 3- dioxolan 2,4-diones (a-hydroxy carboxylic acid anhydrocarboxy— lates) has been prepared by the reaction of phosgene with the copper(II) salt of the appropriate a—-hydroxy carboxylic acid and the potential use of such cyclic compounds as …

Aspects of SU(2|4) symmetric field theories and the Lin-Maldacena geometries
Gauge/gravity duality is an important tool for learning about strongly coupled gauge theories. This thesis explores a set of examples of this duality in which the field theories have SU(2|4) supersymmetry and discrete sets of vacuum solutions. Specifically, we use the duality to propose Lagrangian …

The Synthesis of 5-[(P-Hydroxyphenyl)-2, 4, 6-Tricarbethoxy]-Cyclohexanedione-1, 3.
Papadakis has described the synthesis of (p-hydroxyphenyl)-cyclohexanedione-l, 3 via 5-[(p- acetoxyphenyl)-4, 6-dicarbethoxy]-cyclohexanedione-1, 3 as shown in equations 1-8 of the flow sheet. |The structures of these compounds are such that they can serve as intermediates for the preparation of …

The role of EGFR, HER 2-4, heregulin and downstream signalling in prostate adenocarcinoma
Background Currently evidence regarding influence of the HER tyrosine kinase family - EGFR, HER2, HER3 and HER4 - during disease progression in prostate adenocarcinoma is conflicting – both poor prognosis and no influence on outcome are reported. A small cohort pilot study of paired hormone …

Hypermethylierung-assoziierte Dysregulation der WNT-Antagonisten SFRP 1, 2, 4 und 5 beim Multiplen Myelom
There is increasing evidence that epigenetic changes, especially DNA methylation affecting promoter-associated CpG islands, play an important role in the pathogenesis of hematopoietic malignancies. In this study, we detected simultaneous hypermethylation of multiple WNT inhibitors in both MM cell …

Zur epigenetischen Inaktivierung der Wnt-Antagonisten SFRP-1, -2, -4 und -5 bei der Akuten Myeloischen Leukämie
Acute myeloid leukaemia (AML) originates in the transformation of hematopoietic stem cells, leading to clonal proliferation of immature progenitor cells and severe multilineage bone marrow suppression. In addition to numerous genetic aberrations in AML, it has become evident that epigenetic …

INDUCING ACTIVE SITES IN CLUSTERS: REACTIVITY OF Al13Ix- and Al14Iy- (x=0-2, y=2-4) WITH METHANOL
Size selective reactivity has been observed in pure aluminum cluster anions as a result of Lewis acid and base pairs. Using this a starting point, the goal of this study has been to explore how reactivity is affected with the addition of one or more ligand, which may induce active sites on the …
