Euro-enthusiasm, Euro-rejection, and various shades of grey: The 2014 European Parliament election campaign in the Netherlands. EPIN Commentary No. 18, 29 April 2014

With less than a month to go to the European Parliament (EP) election in the Netherlands on May 22nd, the campaign has barely kicked off. It remains to be seen whether the campaign will address concrete EU policies in a palatable way and whether all parties are able to present clear visions about the future of the European Union. The traditional mainstream parties (the Christian Democratic CDA, Liberal VVD and Social Democratic PvdA) all agree that EU membership is essentially beneficial to the Netherlands, but are careful to stress the shortcomings of the EU in its present form. The parties outside the traditional three that can be expected to do well adopt a more outspoken position on European integration. These include the pro-European Democrats 66 (D66), the Eurosceptic Socialist Party (SP), and the Euroreject Freedom Party (PVV). Yet, reasons for their success should probably not be sought mainlyin their positions on European integration, but rather more in the unpopularity of the incumbent parties and the „second order‟ character of EP elections.

The influence of viral genotypes and rejection episodes on the recurrence of hepatitis C after liver transplantation

Purpose. The aim of this study was to report the influence of hepatitis C virus (HCV) genotype and rejection episodes on the outcome of orthotopic liver transplantation (OLT), hepatitis recurrence, and progression to graft cirrhosis after OLT. Methods. Fifty-three patients who all had undergone OLT for end-stage liver cirrhosis were selected for this study. Hepatitis C genotype was determined. Recurrent hepatitis and rejection were diagnosed based on elevated liver function tests and a liver biopsy. Results. The patients were followed up for a mean of 51.9 +/- 34.3 months. The cumulative survival rate was no different in OLT for hepatitis C and OLT for all other liver diseases. After OLT, serum HCV RNA was detected in 93%. Histological recurrence occurred in 85% of all patients. The 1-, 3-, and 5-year recurrence rates were 48%, 77%, and 85%, respectively. Of the 41 patients with recurrent hepatitis C, 4 (10%) had cirrhosis, 18 (44%) had hepatitis with fibrosis, and 91 (46%) had hepatitis without fibrosis at the end of follow-up. A total of 32% of the patients were infected by HCV genotype 1b and 68% by other HCV genotypes. The recurrence rates were significantly higher in patients infected with genotype 1b than in those with other genotypes (p = 0.04). Twenty of 48 patients (42%) experienced acute rejection. There was a strong association between the number of rejection episodes and the incidence of HCV-related cirrhosis (p < 0.01). Conclusion. Our findings showed the genotype 1b to result in a higher recurrence rate after OLT. On the other hand, rejection episodes were associated with a more rapid progression to graft cirrhosis.

Increased mononuclear cell activation and apoptosis early after human liver transplantation is associated with a reduced frequency of acute rejection

Experimental models of orthotopic liver transplantation (OLT) have shown that the very early events post-OLT are critical in distinguishing immunogenic and tolerogenic reactions. In rodents, increased leukocyte apoptosis and cytokine expression have been demonstrated in tolerogenic strain combinations. Information from human OLT recipients is less abundant. The aim of this study was to determine the amount of early leukocyte activation and apoptosis following human OLT, and to correlate this with subsequent rejection status. Peripheral blood mononuclear cells (PBMC) were isolated from 76 patients undergoing OLT - on the day prior, 5 hrs after reperfusion (day 0), and 18-24 hrs post-OLT (day 1). The mean level of apoptotic PBMCs on post OLT day 1 was higher than healthy recipients (0.9% +/- 0.2 vs. 0.2% +/- 0.1, p = 0.013). Apoptosis was greater in nonrejecting (NR) (1.1% +/- 0.3) compared with acutely-rejecting (R) (0.3% +/- 0.1, p = 0.021) patients. On day 1, PBMC from NR patients had increased expression of IFN-gamma (p = 0.006), IL-10 (p = 0.016), and CD40 ligand (p = 0.02) compared with R. Donor cell chimerism on day 1 did not differ between the groups indicating that this was unlikely to account for increased PBMC apoptosis in the NR group. Interestingly, the level of chimerism on day 0 was significantly higher in NR (3.8% +/- 0.6) compared with R (1.2% +/- 0.4, p = 0.004) patients and there was a close correlation between chimerism on day 0 and cytokine expression on day 1. These results imply that similar mechanisms are occurring in the human liver to promote graft acceptance as in the experimental models of liver transplantation and suggest that strategies that promote liver transplant acceptance in rodents might be applicable to humans.

Effect of mutual coupling on the interference rejection capabilities of linear and circular arrays in CDMA systems

This paper is concerned with assessing the interference rejection capabilities of linear and circular array of dipoles that can be part of a base station of a code-division multiple-access cellular communication system. The performance criteria for signal-to-interference ratio (SIR) improvement employed in this paper is the spatial interference suppression coefficient. We first derive an expression for this figure of merit and then analyze and compare the SIR performance of the two types of arrays. For a linear array, we quantitatively assess the degradation in SIR performance, as we move from array broadside to array end-fire direction. In addition, the effect of mutual coupling is taken into account.

Human growth hormone presented by K14hGH-transgenic skin grafts induces a strong immune response but no graft rejection

Although immune responses leading to rejection of transplantable tumours have been well studied, requirements for epithelial tumour rejection are unclear. Here, we use human growth hormone (hGH) expressed in epithelial cells (skin keratinocytes) as a model neo-self antigen to investigate the consequences of antigen presentation from epithelial cells. Mice transgenic for hGH driven from the keratin 14 promoter express hGH in skin keratinocytes. This hGH-transgenic skin is not rejected by syngeneic non-transgenic recipients, although an antibody response to hGH develops in grafted animals. Systemic immunization of graft recipients with hGH peptides, or local administration of stimulatory anti-CD40 antibody, induces temporary macroscopic graft inflammation, and an obvious dermal infiltrate of inflammatory cells, but not graft rejection. These results suggest that a neo-self antigen expressed in somatic cells in skin can induce an immune response that can be enhanced further by induction of specific immunity systemically or non-specific immunity locally. However, immune responses do not always lead to rejection, despite induction of local inflammatory changes. Therefore, in vitro immune responses and in vivo delayed type hypersensitivity are not surrogate markers for immune responses effective against epithelial cells expressing neoantigens.

Evaluation of cosmic ray rejection algorithms on single-shot exposures

To maximise data output from single-shot astronomical images, the rejection of cosmic rays is important. We present the results of a benchmark trial comparing various cosmic ray rejection algorithms. The procedures assess relative performances and characteristics of the processes in cosmic ray detection, rates of false detections of true objects, and the quality of image cleaning and reconstruction. The cosmic ray rejection algorithms developed by Rhoads (2000, PASP, 112, 703), van Dokkum (2001, PASP, 113, 1420), Pych (2004, PASP, 116, 148), and the IRAF task xzap by Dickinson are tested using both simulated and real data. It is found that detection efficiency is independent of the density of cosmic rays in an image, being more strongly affected by the density of real objects in the field. As expected, spurious detections and alterations to real data in the cleaning process are also significantly increased by high object densities. We find the Rhoads' linear filtering method to produce the best performance in the detection of cosmic ray events; however, the popular van Dokkum algorithm exhibits the highest overall performance in terms of detection and cleaning.
