Regulating working families in the European Union: a history of disjointed strategies

Families in market economies worldwide have long been confronted with the demands of participating in paid work and providing care for their dependent members. The social, economic and political contexts within which families do so differ from country to country but an increasing number of governments are being asked to engage, or better engage, with this important area of public policy. What seems like a relatively simple goal – to enable families to better balance care-giving and paid employment – has raised several difficulties and dilemmas for policy makers which have been approached in different ways. This paper aims to identify and critique the nature and development of the means by which legal engagement with work-family reconciliation has, historically, been framed in the European Union. In doing so, and with reference to specific cohorts of workers, we demonstrate how disjointed the strategies are in relation to working carers and argue that the EU is unlikely to provide the legal framework necessary to bring about effective change in this fundamentally important area of social policy

When is a Partner not a Partner? Conceptualisations of 'family' in EU Free Movement Law

This paper considers the definitions of spouse, civil partner and partner in European Union (EU) free movement of persons law in order to question the EU's heterocentric approach to defining 'family' in this context. It argues that the term 'spouse' should include same-sex married partners in order to ensure that there is no discrimination on the grounds of sexual orientation. It further highlights the problems created by basing free movement rights of civil partners on host state recognition of such partnerships. This approach allows Member States to discriminate on the grounds of sexual orientation and is therefore not compatible with EU equality law in others areas. The position of unmarried or unregistered partners is also considered; in particular, the paper examines the requirement of a duly-attested durable relationship and its impact on same-sex partners wishing to move from one Member State to another. The paper argues that it is time to reconsider the law in this area and bring it in line with the EU's commitment to eliminate discrimination on several grounds, including sexual orientation. © 2011 Taylor and Francis Group, LLC

Two- and three-input TALE-based AND logic computation in embryonic stem cells

Biological computing circuits can enhance our ability to control cellular functions and have potential applications in tissue engineering and medical treatments. Transcriptional activator-like effectors (TALEs) represent attractive components of synthetic gene regulatory circuits, as they can be designed de novo to target a given DNA sequence. We here demonstrate that TALEs can perform Boolean logic computation in mammalian cells. Using a split-intein protein-splicing strategy, we show that a functional TALE can be reconstituted from two inactive parts, thus generating two-input AND logic computation. We further demonstrate three-piece intein splicing in mammalian cells and use it to perform three-input AND computation. Using methods for random as well as targeted insertion of these relatively large genetic circuits, we show that TALE-based logic circuits are functional when integrated into the genome of mouse embryonic stem cells. Comparing construct variants in the same genomic context, we modulated the strength of the TALE-responsive promoter to improve the output of these circuits. Our work establishes split TALEs as a tool for building logic computation with the potential of controlling expression of endogenous genes or transgenes in response to a combination of cellular signals

Rapid construction of insulated genetic circuits via synthetic sequence-guided isothermal assembly

In vitro recombination methods have enabled one-step construction of large DNA sequences from multiple parts. Although synthetic biological circuits can in principle be assembled in the same fashion, they typically contain repeated sequence elements such as standard promoters and terminators that interfere with homologous recombination. Here we use a computational approach to design synthetic, biologically inactive unique nucleotide sequences (UNSes) that facilitate accurate ordered assembly. Importantly, our designed UNSes make it possible to assemble parts with repeated terminator and insulator sequences, and thereby create insulated functional genetic circuits in bacteria and mammalian cells. Using UNS-guided assembly to construct repeating promoter-gene-terminator parts, we systematically varied gene expression to optimize production of a deoxychromoviridans biosynthetic pathway in Escherichia coli. We then used this system to construct complex eukaryotic AND-logic gates for genomic integration into embryonic stem cells. Construction was performed by using a standardized series of UNS-bearing BioBrick-compatible vectors, which enable modular assembly and facilitate reuse of individual parts. UNS-guided isothermal assembly is broadly applicable to the construction and optimization of genetic circuits and particularly those requiring tight insulation, such as complex biosynthetic pathways, sensors, counters and logic gates

Efficacy of lamivudine to prevent hepatitis reactivation in hepatitis B virus-infected patients treated for non-Hodgkin lymphoma.

The association of hepatitis viruses with non-Hodgkin lymphomas (NHL) is not rare. Several authors have reported an exceeding prevalence of hepatitis C virus (HCV)1-3 or of hepatitis B virus (HBV)4,5 infection in patients affected by NHL. A sustained increase of alanine aminotransferase (ALT) associated with high levels of HBV viremia (HBV-DNA) 1 to 2 months after the suspension of chemotherapy has been described in patients suffering from NHL and infected by HBV.7,8 Recently, a nucleotide analogue (lamivudine) was shown to be beneficial in HBV-infected patients with signs of active replication.6 The aim of this study was to investigate the role of lamivudine to treat or to prevent hepatitis reactivation in HBV-infected subjects suffering from NHL and undergoing chemotherapy

Implementing lean management/Six Sigma in hospitals: beyond empowerment or work intensification?

This article analyses a process improvement project based on Lean Six Sigma (LSS) techniques in the emergency department (ED) of a large Australian hospital. We consider perspectives of the clinical and managerial staff involved in the project implementation, its implications for empowerment and work intensification. We find that the project appeared to improve patient flow from the ED to the wards and to have positive implications for some staff. However, these achievements tended to be the result of senior staff using the project to leverage resources and create desirable outcomes, rather than the result of the use of LSS, in particular. We found some evidence of work intensification, but this was attributable to wider systemic issues and budget constraints, rather than being a direct consequence of the use of LSS. We argue that translating LSS from a manufacturing context into the politicised and professionalised context of healthcare changes the usual questions about empowerment or work intensification to questions about the influences of powerful stakeholders

Mediterranean jellyfish sting-induced Tako-Tsubo cardiomyopathy.

We report a case of a 53-year-old woman swimming in the southern Mediterranean Sea on the Calabrian coast that was suddenly stung on her right forearm by a mauve-pink jellyfish. She got extremely scared and while swimming back to the shore, she accused fatigue and an intense itch sensation. She lost consciousness on the beach as a consequence of a condition of pulseless electrical activity

Cardiac stem cells possess growth factor-receptor systems that after activation regenerate the infarcted myocardium, improving ventricular function and long-term survival.

Cardiac stem cells and early committed cells (CSCs-ECCs) express c-Met and insulin-like growth factor-1 (IGF-1) receptors and synthesize and secrete the corresponding ligands, hepatocyte growth factor (HGF) and IGF-1. HGF mobilizes CSCs-ECCs and IGF-1 promotes their survival and proliferation. Therefore, HGF and IGF-1 were injected in the hearts of infarcted mice to favor, respectively, the translocation of CSCs-ECCs from the surrounding myocardium to the dead tissue and the viability and growth of these cells within the damaged area. To facilitate migration and homing of CSCs-ECCs to the infarct, a growth factor gradient was introduced between the site of storage of primitive cells in the atria and the region bordering the infarct. The newly-formed myocardium contained arterioles, capillaries, and functionally competent myocytes that with time increased in size, improving ventricular performance at healing and long thereafter. The volume of regenerated myocytes was 2200 m3 at 16 days after treatment and reached 5100 m3 at 4 months. In this interval, nearly 20% of myocytes reached the adult phenotype, varying in size from 10 000 to 20 000 m3. Moreover, there were 4313 arterioles and 15548 capillaries/mm2 myocardium at 16 days, and 316 arterioles and 39056 capillaries at 4 months. Myocardial regeneration induced increased survival and rescued animals with infarcts that were up to 86% of the ventricle, which are commonly fatal. In conclusion, the heart has an endogenous reserve of CSCs-ECCs that can be activated to reconstitute dead myocardium and recover cardiac function
