The European Union, the World Trade Organization and Cultural Diversity

The chapter maps these trade versus culture developments in the WTO and the positions of the European Union (EU or the Union) and its member states, which were not always coherent. It also looks at the actual results of the trade versus culture contestation – that is, the rules on trade in goods and services in the WTO and how they reflect the need for more policy space in matters of cultural policy, which the EU so ardently pressed for. The chapter further analyses the evolution of both the international trade regulation and the discourse on cultural policy. This discourse has in fact undergone a major transformation in the last two decades, as it has moved from the ‘exception culturelle’ rhetoric, which dominated the Uruguay trade talks, towards a more positive but also more pro-active agenda under the slogan of cultural diversity. The EU has been a major driver of this transformation, which has succeeded in mobilising the international community and ultimately led to the adoption of the 2005 UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions. The chapter concludes by appraisal of the current state of the debate situating it into the broader picture of contemporary global governance. It asks how the EU could effectively pursue its cultural policy aspirations and endorse its cultural diversity agenda in a world of complexity and rapid technological change, in particular in view of the affordances of digital media.

Major differences in organization and availability of health care and medicines for HIV/TB coinfected patients across Europe

OBJECTIVES The aim of the study was to investigate the organization and delivery of HIV and tuberculosis (TB) health care and to analyse potential differences between treatment centres in Eastern (EE) and Western Europe (WE). METHODS Thirty-eight European HIV and TB treatment centres participating in the TB:HIV study within EuroCoord completed a survey on health care management for coinfected patients in 2013 (EE: 17 respondents; WE:21; 76% of all TB:HIV centres). Descriptive statistics were obtained for regional comparisons. The reported data on health care strategies were compared with actual clinical practice at patient level via data derived from the TB:HIV study. RESULTS Respondent centres in EE comprised: Belarus (n = 3), Estonia (1), Georgia (1), Latvia (1), Lithuania (1), Poland (4), Romania (1), the Russian Federation (4) and Ukraine (1); those in WE comprised: Belgium (1), Denmark (1), France (1), Italy (7), Spain (2), Switzerland (1) and UK (8). Compared with WE, treatment of HIV and TB in EE are less often located at the same site (47% in EE versus 100% in WE; P < 0.001) and less often provided by the same doctors (41% versus 90%, respectively; P = 0.002), whereas regular screening of HIV-infected patients for TB (80% versus 40%, respectively; P = 0.037) and directly observed treatment (88% versus 20%, respectively; P < 0.001) were more common in EE. The reported availability of rifabutin and second- and third-line anti-TB drugs was lower, and opioid substitution therapy (OST) was available at fewer centres in EE compared with WE (53% versus 100%, respectively; P < 0.001). CONCLUSIONS Major differences exist between EE and WE in relation to the organization and delivery of health care for HIV/TB-coinfected patients and the availability of anti-TB drugs and OST. Significant discrepancies between reported and actual clinical practices were found in EE.

Polydnavirus of the parasitic wasp Chelonus inanitus (Braconidae): characterization, genome organization and time point of replication

Ultrastructural analysis of the polydnavirus of the braconid wasp Chelonus inanitus revealed that virions consist of one cylindrical nucleocapsid enveloped by a single unit membrane. Nucleocapsids have a constant diameter of 33.7 +/- 1.4 nm and a variable length of between 8 and 46 nm. Spreading of viral DNA showed that the genome consists of circular dsDNA molecules of variable sizes and measurement of the contour lengths indicated sizes of between 7 and 31 kbp. When virions were exposed to osmotic shock conditions to release the DNA, only one circular molecule was released per particle suggesting that the various DNA molecules are singly encapsidated in this bracovirus. The viral genome was seen to consist of at least 10 different segments and the aggregate genome size is in the order of 200 kbp. By partial digestion of viral DNA with HindIII or EcoRI in the presence of ethidium bromide and subsequent ligation with HindIII-cut pSP65 or EcoRI-cut pSP64 and transfection into Escherichia coli, libraries of 103 HindIII and 23 EcoRI clones were obtained. Southern blots revealed that complete and unrearranged segments were cloned with this approach, and restriction maps for five segments were obtained. Part of a 16.8 kbp segment was sequenced, found to be AT-rich (73%) and to contain six copies of a 17 bp repeated sequence. The development of the female reproductive tract in the course of pupal-adult development of the wasp was investigated and seen to be strictly correlated with the pigmentation pattern. By the use of a semiquantitative PCR, replication of viral DNA was observed to initiate at a specific stage of pupal-adult development.

Organization and function of platelet glycoprotein Ib-IX complex

Glycoprotein (GP) Ib-IX complex, the second most abundant receptor expressed on the platelet surface, plays critical roles in haemostasis and thrombosis by binding to its ligand, von Willebrand factor (vWF). Defect or malfunction of the complex leads to severe bleeding disorders, heart attack or stroke. Comprised of three type I transmembrane subunits—GPIbα, GPIbβ and GPIX, efficient expression of the GPIb-IX complex requires all three subunits, as evident from genetic mutations identified in the patients and reproduced in transfected Chinese hamster ovary (CHO) cells. However, how the subunits are assembled together and how the complex function is regulated is not fully clear. By probing the interactions among the three subunits in transfected cells, we have demonstrated that the transmembrane domains of the three subunits interact with one another, facilitating formation of the two membrane-proximal disulfide bonds between GPIbα and GPIbβ. We have also identified the interface between extracellular domains of GPIbβ and GPIX, and provided evidence suggesting a direct interaction between extracellular domains of GPIbα and GPIX. All of these interactions are not only critical for correct assembly and consequently efficient expression of the GPIb-IX complex on the cell surface, but also for its function, such as the proper ligand binding, since removing the two inter-subunit disulfide bonds significantly hampers vWF binding to the complex under both static and physiological flow conditions. The two inter-subunit disulfide bonds are also critical for regulating the ectodomain shedding of GPIbα by the GPIbβ cytoplasmic domain. Mutations in the juxtamembrane region of the GPIbβ cytoplasmic domain deregulate GPIbα shedding, and such deregulation is further enhanced when the two inter-subunit disulfide bonds are removed. In summary, we have established the overall organization of the GPIb-IX complex, and the importance of proper organization on its function. ^

Human ATP-binding cassette transporter 1 (ABC1): Genomic organization and identification of the genetic defect in the original Tangier disease kindred

Tangier disease is characterized by low serum high density lipoproteins and a biochemical defect in the cellular efflux of lipids to high density lipoproteins. ABC1, a member of the ATP-binding cassette family, recently has been identified as the defective gene in Tangier disease. We report here the organization of the human ABC1 gene and the identification of a mutation in the ABC1 gene from the original Tangier disease kindred. The organization of the human ABC1 gene is similar to that of the mouse ABC1 gene and other related ABC genes. The ABC1 gene contains 49 exons that range in size from 33 to 249 bp and is over 70 kb in length. Sequence analysis of the ABC1 gene revealed that the proband for Tangier disease was homozygous for a deletion of nucleotides 3283 and 3284 (TC) in exon 22. The deletion results in a frameshift mutation and a premature stop codon starting at nucleotide 3375. The product is predicted to encode a nonfunctional protein of 1,084 aa, which is approximately half the size of the full-length ABC1 protein. The loss of a Mnl1 restriction site, which results from the deletion, was used to establish the genotype of the rest of the kindred. In summary, we report on the genomic organization of the human ABC1 gene and identify a frameshift mutation in the ABC1 gene of the index case of Tangier disease. These results will be useful in the future characterization of the structure and function of the ABC1 gene and the analysis of additional ABC1 mutations in patients with Tangier disease.

Corepressor-induced organization and assembly of the biotin repressor: A model for allosteric activation of a transcriptional regulator

The Escherichia coli biotin repressor binds to the biotin operator to repress transcription of the biotin biosynthetic operon. In this work, a structure determined by x-ray crystallography of a complex of the repressor bound to biotin, which also functions as an activator of DNA binding by the biotin repressor (BirA), is described. In contrast to the monomeric aporepressor, the complex is dimeric with an interface composed in part of an extended β-sheet. Model building, coupled with biochemical data, suggests that this is the dimeric form of BirA that binds DNA. Segments of three surface loops that are disordered in the aporepressor structure are located in the interface region of the dimer and exhibit greater order than was observed in the aporepressor structure. The results suggest that the corepressor of BirA causes a disorder-to-order transition that is a prerequisite to repressor dimerization and DNA binding.
