2.6 Judge William F. Frank, Chief Justice, Missouri State Supreme Court

In February, 1937, the Court, in an opinion by Chief Justice William F. Frank, issued their verdict that supported the Missouri statute that allowed for out-of-state tuition for Missouri blacks to continue their education if the desired program was not offered at Lincoln University Once again, the legal team of Lloyd Gaines was not undaunted.

Crystal structure of a thermostable type B DNA polymerase from Thermococcus gorgonarius

Most known archaeal DNA polymerases belong to the type B family, which also includes the DNA replication polymerases of eukaryotes, but maintain high fidelity at extreme conditions. We describe here the 2.5 Å resolution crystal structure of a DNA polymerase from the Archaea Thermococcus gorgonarius and identify structural features of the fold and the active site that are likely responsible for its thermostable function. Comparison with the mesophilic B type DNA polymerase gp43 of the bacteriophage RB69 highlights thermophilic adaptations, which include the presence of two disulfide bonds and an enhanced electrostatic complementarity at the DNA–protein interface. In contrast to gp43, several loops in the exonuclease and thumb domains are more closely packed; this apparently blocks primer binding to the exonuclease active site. A physiological role of this “closed” conformation is unknown but may represent a polymerase mode, in contrast to an editing mode with an open exonuclease site. This archaeal B DNA polymerase structure provides a starting point for structure-based design of polymerases or ligands with applications in biotechnology and the development of antiviral or anticancer agents.

Activation of NF-κB is required for hypertrophic growth of primary rat neonatal ventricular cardiomyocytes

The transcription factor NF-κB regulates expression of genes that are involved in inflammation, immune response, viral infection, cell survival, and division. However, the role of NF-κB in hypertrophic growth of terminally differentiated cardiomyocytes is unknown. Here we report that NF-κB activation is required for hypertrophic growth of cardiomyocytes. In cultured rat primary neonatal ventricular cardiomyocytes, the nuclear translocation of NF-κB and its transcriptional activity were stimulated by several hypertrophic agonists, including phenylephrine, endothelin-1, and angiotensin II. The activation of NF-κB was inhibited by expression of a “supersuppressor” IκB�� mutant that is resistant to stimulation-induced degradation and a dominant negative IκB kinase (IKKβ) mutant that can no longer be activated by phosphorylation. Furthermore, treatment with phenylephrine induced IκB�� degradation in an IKK-dependent manner, suggesting that NF-κB is a downstream target of the hypertrophic agonists. Importantly, expression of the supersuppressor IκB�� mutant or the dominant negative IKKβ mutant blocked the hypertrophic agonist-induced expression of the embryonic gene atrial natriuretic factor and enlargement of cardiomyocytes. Conversely, overexpression of NF-κB itself induced atrial natriuretic factor expression and cardiomyocyte enlargement. These findings suggest that NF-κB plays a critical role in the hypertrophic growth of cardiomyocytes and may serve as a potential target for the intervention of heart disease.

All the rest is merely exploitation and perseverance : the poster art of Frank Kozik

"The history of poster art tends to focus on the art of Henri Toulouse-Latrec, Jules Cheret, and Alfonse Mucha, while leaving out or barely mentioning the work of artists such as Wes Wilson, Stanley Mouse, and Alton Kelley. The aim of this thesis is to widen the gaze of poster art by centering on a contemporary rock poster artist: Frank Kozik. By focusing on formal and sociological analysis ofa number of Kozik's posters, I illustrate how he not only fits in with the arc of poster art development, but also influences it into the next century"

The supergiant B[e] star LHA 115-S 18 - binary and/or luminous blue variable?

Context. The mechanism by which supergiant (sg)B[e] stars support cool, dense dusty discs/tori and their physical relationship with other evolved, massive stars such as luminous blue variables is uncertain. Aims. In order to investigate both issues we have analysed the long term behaviour of the canonical sgB[e] star LHA 115-S 18. Methods. We employed the OGLE II-IV lightcurve to search for (a-)periodic variability and supplemented these data with new and historic spectroscopy. Results. In contrast to historical expectations for sgB[e] stars, S18 is both photometrically and spectroscopically highly variable. The lightcurve is characterised by rapid aperiodic ` aring' throughout the 16 years of observations. Changes in the high excitation emission line component of the spectrum imply evolution in the stellar temperature - as expected for luminous blue variables - although somewhat surprisingly, spectroscopic and photometric variability appears not to be correlated. Characterised by emission in low excitation metallic species, the cool circumstellar torus appears largely unaffected by this behaviour. Finally, in conjunction with intense, highly variable He ii emission, X-ray emission implies the presence of an unseen binary companion. Conclusions. S18 provides observational support for the putative physical association of (a subset of) sgB[e] stars and luminous blue variables. Given the nature of the circumstellar environment of S18 and that luminous blue variables have been suggested as SN progenitors, it is tempting to draw a parallel to the progenitors of SN1987A and SN2009ip. Moreover the likely binary nature of S18 strengthens the possibility that the dusty discs/tori that characterise sgB[e] stars are the result of binary-driven mass-loss; consequently such stars may provide a window on the short lived phase of mass-transfer in massive compact binaries.
