The role of Private Equity-firms in the formation of strategic alliances
2014
This research analyses the role of Private Equity firms in the formation of strategic alliances within the field of the French Private Equity market. We start to provide evidence of its importance from new survey information, before offering an explanation of the organizational phenomenon. The study addresses the questions of how and why Private Equity firms act as relational intermediaries to help their portfolio companies form alliances. Both questions are investigated in the light of the Private Equity firms’ contribution to the value creation process that comes with alliance formation. Answers are provided by means of three jointly used theoretical frameworks: (1) mainstream theories (t…

The human liver fatty acid binding protein (FABP1) gene is activated by FOXA1 and PPARα; and repressed by C/EBPα: Implications in FABP1 down-regulati…
2013
Liver fatty acid binding protein (FABP1) prevents lipotoxicity of free fatty acids and regulates fatty acid trafficking and partition. Our objective is to investigate the transcription factors controlling the human FABP1 gene and their regulation in nonalcoholic fatty liver disease (NAFLD). Adenovirus-mediated expression of multiple transcription factors in HepG2 cells and cultured human hepatocytes demonstrated that FOXA1 and PPARα are among the most effective activators of human FABP1, whereas C/EBPα is a major dominant repressor. Moreover, FOXA1 and PPARα induced re-distribution of FABP1 protein and increased cytoplasmic expression. Reporter assays demonstrated that the major basal activ…
Improving point matching on multimodal images using distance and orientation automatic filtering
2016
International audience; Speed Up Robust Features SURF is one of the most popular and efficient methods used for image registration task. In order to achieve a correct registration, a good matching of feature point is required. However in the case of multimodal images, the high and non-linear intensity changes between different modalities led to many outliers (mismatching of detected points) and consequently a fail in the registration. Therefore, in this paper we introduce an efficient method devoted to the detection and removal of such outlier. It's based on an automatic filtering of outliers on both distance and orientation between features points. We tested our proposed method on a set of…
Joan Roís de Corella, la seua vida i el seu entorn: noves dades per a la història de la cultura en la València del segle xv
2014
This article offers a full updating of the biographical records of the writer Joan Roís de Corella (1435-1497) and his family: his great-grandparents, grandparents, parents, siblings and children. All data are presented in a systematic way, generation by generation, and a new vision of the writer himself is offered. In its documentary section, 432 documents are transcribed or summarised, dating from 1373 to 1516. A broad range of new archival data is presented; other previously known data are corrected or improved. Some examples: Joan Roís de Corella had four children: Magdalena (born 1459), Maria, Joan and Estefania, the latter two by Isabel Martínez de Vera. Joan Roís de Corella was widel…
How Long-Term Contracts can Mitigate Inefficient Renegotiation Arising Due to Loss Aversion
2021
A loss-averse buyer and seller face an uncertain environment. Should they write a long-term contract or wait until the state of the world is realized? I show that simple long-term contracts perform better than insinuated in Herweg and Schmidt (2015), even though loss aversion makes renegotiation sometimes inefficient. During renegotiation, the outcome induced by the long-term contract constitutes the reference point to which the parties compare gains and losses induced by the renegotiated transaction. Whereas Herweg and Schmidt consider that the long-term contract is always performed, it should not in "bad" states. This alters the threat point in renegotiation, making it easier to renegotia…
Focal Transcriptional Activity of Murine Cytomegalovirus during Latency in the Lungs
1999
ABSTRACT Interstitial pneumonia is a frequent and critical manifestation of human cytomegalovirus (CMV) disease in immunocompromised patients, in particular in recipients of bone marrow transplantation. Previous work in the murine CMV infection model has identified the lungs as a major organ site of CMV latency and recurrence. It was open to question whether the viral genome is transcriptionally silent or active during latency. Transcription could be latency associated and thus be part of the latency phenotype. Alternatively, transcriptional activity could reflect episodes of reactivation. We demonstrate here that transcription of the immediate-early (IE) transcription unit ie1-ie3 selectiv…
Hyperthermia Enhances CD95-Ligand Gene Expression in T Lymphocytes
2004
Abstract Hyperthermia represents an interesting therapeutic strategy for the treatment of tumors. Moreover, it is able to regulate several aspects of the immune response. Fas (APO-1/CD95) and its ligand (FasL) are cell surface proteins whose interaction activates apoptosis of Fas-expressing targets. In T cells, the Fas-Fas-L system regulates activation-induced cell death, is implicated in diseases in which lymphocyte homeostasis is compromised, and plays an important role during cytotoxic and regulatory actions mediated by these cells. In this study we describe the effect of hyperthermia on activation of the fas-L gene in T lymphocytes. We show that hyperthermic treatment enhances Fas-L-med…
Decomposition studies of group 6 hexacarbonyl complexes. Part 1: Production and decomposition of Mo(CO)6 and W(CO)6
2015
Abstract Chemical studies of superheavy elements require fast and efficient techniques, due to short half-lives and low production rates of the investigated nuclides. Here, we advocate for using a tubular flow reactor for assessing the thermal stability of the Sg carbonyl complex – Sg(CO)6. The experimental setup was tested with Mo and W carbonyl complexes, as their properties are established and supported by theoretical predictions. The suggested approach proved to be effective in discriminating between the thermal stabilities of Mo(CO)6 and W(CO)6. Therefore, an experimental verification of the predicted Sg–CO bond dissociation energy seems to be feasible by applying this technique. By in…
