2,9-Dimethyl-7-phenyl-N-(4-methylÂphenÂyl)dibenzo[b,h][1,6]naphthyridin-6-amine
The title compound, C31H25N3, was synthesized from 6,4′,4′′-trimethyl-2,4-bisÂ(N-phenylÂamino)Âquinoline and is the first structural example containing a phenyl and phenylÂamino fragment attached to a fused dibenzo[1,6]naphthyridine moiety. The fused tetraÂcyclic ring system is essentially planar [r.m.s. deviation = 0.08 (3) Å]. The phenyl ring and the phenylÂamino group are inclined by 82.68 (6) and 35.31 (5)°, respectively, to the mean plane of the fused tetraÂcyclic ring system. A weak intraÂmolecular N—H⋯π(arene) interÂaction may in part influence the conformation of the molÂecule. In the crystal, molÂecules are linked by weak interÂmolecular C—H⋯N hydrogen bonds into centrosymmetric dimers. Additional stabilization is provided by weak C—H⋯π and π–π stacking interÂactions [centroid–centroid distances = 3.834 (2) and 3.898 (1) Å]
7-(2-ChloroÂphenÂyl)-2,6,9-trimethylÂdibenzo[b,h][1,6]naphthyridine
In the title compound, C25H19ClN2, the dibenzo[b,h][1,6]naphthyridine system is planar to within 0.16 (2) Å, and the chloroÂphenyl ring is inclined to it by 82.53 (7)°. In the crystal, molÂecules are linked by C—H⋯N hydrogen bonds, forming chains propagating in [100]. There are also a number of weak π–π stacking interÂactions present [centroid–centroid distances = 3.8531 (1) and 3.7631 (1) Å]

Perceptions of the Impact of Positive Action in EU and non-EU Countries
yesAbstract: Around the world, inequalities exist around boundaries of race, social class, gender, disability,
religious beliefs and sexual orientation, often resulting from past and current discriminatory
practices. Governments have taken certain measures, including enacting policies such as positive action,
to remedy such discrimination. This paper provides a comparative analysis of perceptions of the impact
of positive action in seven EU and three non-EU countries. The study adopted participatory methods
including consensus workshops, interviews and policy analysis to obtain data from designers of positive
action. Findings are discussed, conclusions drawn and wide-ranging recommendations are made at
the EC, individual countries and organisational levels
Quantitative Analysis of Dynamic Protein Interactions during Transcription Reveals a Role for Casein Kinase II in Polymerase-associated Factor (PAF) Complex Phosphorylation and Regulation of Histone H2B Monoubiquitylation
Using affinity purification MS approaches, we have identified a novel role for casein kinase II (CKII) in the modification of the polymerase associated factor complex (PAF-C). Our data indicate that the facilitates chromatin transcription complex (FACT) interacts with CKII and may facilitate PAF complex phosphorylation. Posttranslational modification analysis of affinity-isolated PAF-C shows extensive CKII phosphorylation of all five subunits of PAF-C, although CKII subunits were not detected as interacting partners. Consistent with this, recombinant CKII or FACT-associated CKII isolated from cells can phosphorylate PAF-C in vitro, whereas no intrinsic kinase activity was detected in PAF-C samples. Significantly, PAF-C purifications combined with stable isotope labeling in cells (SILAC) quantitation for PAF-C phosphorylation from wild-type and CKII temperature-sensitive strains (cka1Δ cka2–8) showed that PAF-C phosphorylation at consensus CKII sites is significantly reduced in cka1Δ cka2–8 strains. Consistent with a role of CKII in FACT and PAF-C function, we show that decreased CKII function in vivo results in decreased levels of histone H2B lysine 123 monoubiquitylation, a modification dependent on FACT and PAF-C. Taken together, our results define a coordinated role of CKII and FACT in the regulation of RNA polymerase II transcription through chromatin via phosphorylation of PAF-C
Positive Action Measures Across Different Equality Grounds, Organisations and Sectors in European and Non-european Countries
yesAbstract: This article is based on a large-scale European Commission project on international perspectives
on positive action measures. The paper presents an analysis of the perceptions of positive
action held by respondents from all the countries participating in an international survey, focussing
specifically upon differences across equality grounds, sector and organisation type. This paper will
also provide examples of positive action being applied in European and non-European countries that
participated in the study. The study adopted extensive literate and online survey to obtain data from
designers of positive action. Findings are discussed, conclusions drawn and wide-ranging recommendations
are made at the European Commission, individual countries and organisational levels
