Lesbian and gay parents and reproductive technologies: The 2008 Australian and UK reforms

This article analyses the laws that govern the allocation of parental responsibility for children conceived through non-coital reproduction by lesbians and gay men in England/Wales and Australia. In 2008 both jurisdictions introduced important reforms affecting this area of law, providing new options for the legal recognition of parent–child relationships in lesbian and gay households. However, the practical usefulness or effectiveness of the reforms may be limited by the excessive complexity or obscurity of the system of parental responsibility thus introduced. Furthermore, the reform Acts encourage the formation of some family structures—especially homonuclear families—while discouraging the emergence of more imaginative and cooperative parenting configurations at odds with heteronormative parenting scripts. Only through a clearer commitment to intentionality as a ground for the allocation of parental responsibility will future reform be likely to adequately protect the interests of lesbian and gay parents and their children.

The role of competition and state aid policy in financial and monetary law

During the financial crisis, companies and lenders found themselves in distressed situations. Competition authorities across the globe had to deal with controversial issues such as the application of the failing firm defence in merger transactions as well as assessment of emergency aid granted by states. This article considers competition policy in periods of crisis, in particular the failing firm defence in merger control and its state aid policy.

Differential regulation of Krüppel-like factor family transcription factor expression in neonatal rat cardiac myocytes: effects of endothelin-1, oxidative stress and cytokines

Krüppel-like transcription factors (Klfs) modulate fundamental cell processes. Cardiac myocytes are terminally-differentiated, but hypertrophy in response to stimuli such as endothelin-1. H2O2 or cytokines promote myocyte apoptosis. Microarray studies of neonatal rat myocytes identified several Klfs as endothelin-1-responsive genes. We used quantitative PCR for further analysis of Klf expression in neonatal rat myocytes. In response to endothelin-1, Klf2 mRNA expression was rapidly increased ( approximately 9-fold; 15-30 min) with later increases in expression of Klf4 and Klf6 ( approximately 5-fold; 30-60 min). All were regulated as immediate early genes (cycloheximide did not inhibit the increases in expression). Klf5 expression was increased at 1-2 h ( approximately 13-fold) as a second phase response (cycloheximide inhibited the increase). These increases were transient and attenuated by U0126. H2O2 increased expression of Klf2, Klf4 and Klf6, but interleukin-1beta or tumor necrosis factor alpha downregulated Klf2 expression with no effect on Klf4 or Klf6. Of the Klfs which repress transcription, endothelin-1 rapidly downregulated expression of Klf3, Klf11 and Klf15. The dynamic regulation of expression of multiple Klf family members in cardiac myocytes suggests that, as a family, they are actively involved in regulating phenotypic responses (hypertrophy and apoptosis) to extracellular stimuli.
