For industrial applications, holographic interferometry and electronic speckle pattern interferometry techniques using visible laser light are often too sensitive to external perturbations. Consequently they require too much stability, preventing their widespread use in field applications. One simple idea to overcome this problem is to increase the wavelength of the laser light. We considered the 10 µm wavelength range corresponding to well known CO2 laser and because imagers exist in this spectral range. One other important advantage is that the strain/displacement measurement range is larger than the equivalent techniques in visible light. We will present the preliminary experiences performed so far with components available in our lab. Mainly, we show in-plane electronic speckle pattern interferometry and for the first time digital holographic interferometry. We also discuss specific problems related to the wavelength increase.

This book brings images of holy motherhood and childbearing into the centre of an art-historical enquiry. By focusing on images of St Anne and the Holy Kinship in Books of Hours made for aristocratic women in relation to the dynastic importance of heirs, it reassesses the role of the female viewer as an active agent in the interpretation of pictures and popular devotional rites. Holy motherhood combines an innovative methodology that draws on art-historical and contemporary gender studies with empirical evidence from fifteenth-century manuscripts, to show how images worked not only to script and maintain gender and social roles within patriarchal society but also to offer viewers ways of managing those roles. Some of the manuscripts discussed are relatively unknown and their images and texts are made available to readers for the first time. The study begins by problematising the notion that intimate, post-partum images of holy childbirth found in Books of Hours provide a window onto the medieval past and women's viewing habits. Through an adaptation of Baxadall's 'period eye', the first part of the book explores how aristocratic lay women - and men - viewed and interpreted images of childbirth by considering their familiarity with prayers for childbirth, the lying-in ceremony and the rite of churching. The second part uses this methodology to interpret the images and prayers in six bespoke manuscripts, including the Fitzwilliam Hours, owned by several Angevin and Breton duchesses, and the Hours of Marguerite of Foix. The book will appeal to advanced students, academics and researchers of Art History, Illuminated Manuscripts, Medieval History and Gender Studies. [less ▲]

EL LIBRO El presente volumen pretende introducir en el ámbito hispanoamericano las nuevas aproximaciones teóricas y las diferentes apuestas metodológicas surgidas durante las dos últimas décadas para abordar el estudio de la figura del autor y el problema de la autorialidad. Desde el desafío lanzado por Michel Foucault en su ensayo "¿Qué es un autor?", y que encabeza esta compilación, se han producido distintas respuestas y elaboraciones por parte de un grupo de investigadores que provienen de coordenadas geográficas tan diversas como Francia, Bélgica, Suiza, Canadá e Israel. Estos son los escritores que integran en su mayor parte esta compilación, con temas como la historia de la figura autorial, la imagen y la postura de autor, y el dilema y los mitos del autor moderno; además, el texto ofrece aplicaciones concretas, tanto desde una perspectiva europea (mediante el estudio de autores como Arthur Rimbaud, Gide, Pierre Michon y Jean Rouaud) como desde una colombiana (con análisis sobre José Asunción Silva, Jorge Gaitán Durán, Fernando Vallejo y Efraim Medina Reyes). La invención del autor permite conocer los desarrollos más actuales y destacados en la materia, y abre numerosos ejes de investigación en una temática especialmente importante y sensible en la actualidad, pero sobre la cual se ha publicado muy poco en nuestro medio; de ahí la importancia de esta antología para el debate académico.

HOME BLOOD PRESSURE IN KIDNEY TRANSPLANT RECIPIENTS (KTR)-Validity of different schedules of self-monitoring A. Saint-Remy, L. Weekers, C. Bonvoisin, P. Xhignesse, B.Dubois, JM. Krzesinski NEPHROLOGY - CHU LIEGE AIM: Office blood pressure (OBP), 24-h ambulatory monitoring (ABPM) and home self- monitoring (HBP) allow assessing BP control in treated HT patients. For HBP, ESH guidelines recommend 7 days of measurements but that duration is questioned. The present study analyzed the agreement between daytime ABP and different schedules for HBP in 70 treated hypertensive KTR. METHOD: BP control defined by OBP <140/90 and daytime ABP or HBP <135/85 mmHg was tested in 70 KTR (mean age 56 ± 11 y; mean graft survival 7 ± 6.6 y). OBP and HBP were measured with an Omron M6 and 24-h ABPM with a Spacelabs 90207. HBP was measured on consecutive days (2 times in morning and 2 times at evening/day), the first day was discarded for the mean calculation. Agreement between daytime and HBP was studied when HBP was measured during 7, 5 or 3 days. RESULTS: BP was uncontrolled in 50% of the KTR based on OBP, in 61 % according to daytime ABP and even in 64 % with HBP. Sensitivity (Se) testing agreement between daytime ABP and HBP decreased progressively when number of days was shortened: the highest Se was observed for a 7 days duration with 1st day discarded (86 %). Specificity (Sp) fluctuated around 70 % and was the highest for a 5 (73 %) and 3 days schedule. However the 5 days schedule had higher Se (83 %) than the 3 days. Proportions of KTR correctly classified according to daytime ABP were 79 %, 79 % and 78 % with the 7, 5 or 3 days schedule, respectively. CONCLUSIONS: HBP, easier and less restricting method than 24h ABPM, is a good alternative to daytime ABPM as nearly 80 % of treated KTR were similarly classified. HBP recording period can be shortened to 5 days according to Se and Sp. A 3 days schedule seems more risky reducing the chance to identify masked HT due to a decreased drug adherence. [less ▲]

The link between transport energy consumption and land use patterns has been the focus of a considerable amount of academic works over the past decades. While many empirical researches are backed up with solid statistical techniques, most of them do not fully consider the influence of scale underlying empirical quantitative investigations. Using fine-scale home-to-work commuting data for Wallonia (Belgium), this paper re-evaluates Breheny’s (1995) assertion that urban structure should hold the characteristics of major cities if substantial energy savings are to be achieved. A local scale approach highlights efficient settlements in terms of transport energy consumption not only within major towns, butalso within remote rural areas. Furthermore, results suggest that influencing the urban form following local energy efficient examples rather than regional ones could also yield significant gains, without an extreme policy stance of re-urbanisation in major cities.

The transformation of a cell and the acquisition of the invasive and metastatic phenotype result from the activation of a group of complex cellular processes rather than from the effect of a single gene product. It is likely that the coordination of the multiple genes involved in malignancy is under the control of a few genes that act as master genes or orchestrator genes. The latter probably code for transcription factors that control the genetic program for tumor invasion and metastasis. Homeobox genes are a family of transcription factors that contain a 183 bp highly conserved nucleotide sequence coding for a 61 amino acid domain that binds specifically to DNA. First discovered in Drosophila as genes controlling segmentation and segment identity, homeobox genes have since been identified in many other species including nematodes, frog, mouse and human. There is strong support for the suggestion that homeobox genes play a key role in development and differentiation. In humans, there are 38 homeobox genes organized in four clusters that are localized on chromosomes 2, 7, 12 and 17. The specific functions of each of these genes are generally unknown. Alterations in expression of several homeobox genes have been reported in a variety of malignant lesions, suggesting that they could play a role in the development of cancer. Using reverse transcriptase reaction coupled with polymerase chain reaction and degenerate oligonucleotides corresponding to the 5' and 3' ends of the highly conserved homeodomain, we amplified 130 bp cDNA fragments from the human breast cancer cell line MCF7 that were subsequently cloned into pBluescript vector. Sequencing of the clones, resulted in the identification of the homeodomains of four different human homeobox genes: HOXB6, HOXA1, HOXA10 and HOXC6. Further studies should determine the specific role of these four homeobox genes in the development and progression of human breast cancer and potentially determine if they might be good targets for gene therapy.

Bovine leukemia virus (BLV) tax is an essential gene involved in the transcriptional activation of viral expression. Tax is also believed to be implicated in leukemogenesis because of its ability to immortalize primary cells in vitro. To gain insight into the molecular pathways mediating the activities of this important gene, we identified cellular proteins interacting with Tax. By means of a two-hybrid approach, we show that Tax specifically interacts with MSX2, a general repressor of gene expression. GST pull-down experiments and co-immunoprecipitation assays further confirmed binding specificity. Furthermore, the N-terminal residues 1-79 of MSX2 are required for binding, whereas the C-terminal residues 201-267 of MSX2 do not play a critical role. Whereas the oncogenic potential of Tax in primary cells was only slightly affected by overexpression of MSX2, the other function of Tax, namely LTR-dependent transcriptional activation, was inhibited by MSX2 in human HeLa and bovine B-lymphoblastoid (BL3) cell lines. This MSX2 repression function can be counteracted by overexpression of transcription factors CREB2 and RAP74. The Tax/MSX2 interplay thus results in repression of viral transcriptional activation possibly acting as a regulatory feedback loop. Importantly, this viral gene silencing is not strictly associated with a concomitant loss of Tax oncogenicity as measured by its ability to immortalize primary cells. And interestingly, MSX2 also interacts with and inhibits the transactivation function of the related Tax1 protein encoded by the Human T-cell leukemia virus type 1 (HTLV-1). [less ▲]

Hox proteins are conserved homeodomain transcription factors known to be crucial regulators of animal development. As transcription factors, the functions and modes of action (co-factors, target genes) of Hox proteins have been very well studied in a multitude of animal models. However, a handful of reports established that Hox proteins may display molecular activities distinct from gene transcription regulation. Here, we reveal that Hoxa2 interacts with 20S proteasome subunits and RCHY1 (also known as PIRH2), an E3 ubiquitin ligase that targets p53 for degradation. We further show that Hoxa2 promotes proteasome-dependent degradation of RCHY1 in an ubiquitin-independent manner. Correlatively, Hoxa2 alters the RCHY1-mediated ubiquitination of p53 and promotes p53 stabilization. Together, our data establish that Hoxa2 can regulate the proteasomal degradation of RCHY1 and stabilization of p53. [less ▲]
