Don't Raise the Retirement Age! An Experiment on Opposition to Pension Reforms and East-West Differences in Germany

For policy reforms to increase a society's welfare, reliable information on people's prefer-ences and expectations is crucial. Representative opinion polls, often involving simplified questions about the complex topics under debate, are an important source of information for both policy-makers and the public. Do people's answers to these poll questions reliably reflect their preferences and expectations, or does fundamental, undiscriminating opposition to reforms distort them? We address this question in the context of a recent German pension reform which raised the statutory retirement age by two years to age 67. By introducing an experiment into a representative household survey, we are able to disentangle expectations of work ability at retirement and fundamental opposition. Our results show that expected work ability declines substantially with increasing target age (63, 65, or 67 years). Answers from West German respondents reflect their current life situation as well as individual health and other risk factors. However, a fundamental opposition to reforms of the welfare state appears to strongly affect responses from East German households.retirement, health, work ability, survey experiment, public opinion poll, PAYG pension system, East Germany

Fluttering of the Tail Surfaces of an Airplane and the Means for Its Prevention

The present article, which constitutes a continuation of the work of Von Baumhauer and Konig, will therefore be restricted to the fluttering of the tail surfaces and especially to oscillations of the horizontal empennage. This will also illustrate the characteristics of all other phenomena of fluttering

On Atomization in Carburetors

The outstanding quantity of the whole atomization problem is the characteristic K, and therefore the ratio of the static pressure of the air stream with respect to the liquid to the surface tension of the liquid. The higher its value, the better the atomization. The shape of the Venturi tube plays a secondary role. The increase of section beyond the throat had best not be too abrupt

Rente mit 67: Wie lange die Deutschen arbeiten können und wollen

Unter den Reformplänen der großen Koalition wurde und wird die Verlängerung der Lebensarbeitszeit besonders kontrovers diskutiert. Beatrice Scheubel, Center for Economic Studies (CES), und Joachim Winter, Ludwig-Maximilians-Universität München, untersuchen das häufig vorgebrachten Argument, die Menschen seien im Alter gesundheitlich nicht mehr fit genug, um bis 67 arbeiten zu können. Sie analysieren repräsentative Befragungsdaten aus der Mannheimer SAVE-Studie über die Erwartungen der noch arbeitenden Bevölkerung hinsichtlich der individuellen Arbeitsfähigkeit im Alter. Es zeigt sich, dass das Bild, das in der öffentlichen Diskussion gezeichnet wird, zu düster ist. Die verbreitete Ablehnung einer Erhöhung des Rentenalters geht nicht unbedingt mit einer niedrigen individuellen Arbeitsfähigkeit im Alter einher.Altersgrenze, Rentenreform, Gesetzliche Rentenversicherung, Deutschland

Safety and Immunogenicity of MAGE-A3 Cancer Immunotherapeutic with or without Adjuvant Chemotherapy in Patients with Resected Stage IB to III MAGE-A3-Positive Non-Small-Cell Lung Cancer

Introduction: To assess the safety and immunogenicity of MAGE-A3 immunotherapeutic in patients with stage IB-III MAGE-A3-positive non-small-cell lung cancer (NSCLC) who were or were not undergoing standard cisplatin/vinorelbine chemotherapy. Methods: This open, prospective, multicenter, parallel-group phase I study (NCT00455572) enrolled patients with resected (cohorts 1-3) or unresectable (cohort 4) MAGE-A3-positive NSCLC. MAGE-A3 immunotherapeutic (300 g recombinant MAGE-A3 formulated with AS15) was administered (eight doses, 3 weeks apart) concurrent with (cohort 1), after (cohort 2), or without (cohort 3) standard-adjuvant chemotherapy, or after standard radiotherapy and/or chemotherapy (cohort 4). Results: Sixty-seven patients received greater than or equal to 1 dose of MAGE-A3 immunotherapeutic. Grade 3/4 adverse events (AEs) were reported for 16 out of 19 (84%), 2 out of 18 (11%), 5 out of 18 (28%), and 1 out of 12 (8%) patients in cohorts 1, 2, 3, and 4, respectively. Many grade 3/4 AEs in cohort 1 (e.g., neutropenia) were typical of chemotherapy. Six patients, including three in cohort 1, reported study treatment-related grade 3/4 AEs (injection-site reactions or musculoskeletal/back pain, which resolved within 5 days). One patient (in cohort 4) died, but this and the other serious adverse events were not study treatment related. MAGE-A3-specific antibody responses to immunotherapy were induced in all patients evaluated in all cohorts. MAGE-A3-specific CD4(+) T-cell responses to immunotherapy were detected in 4 out of 11 (36%), 4 out of 15 (27%), 2 out of 8 (25%), and 5 out of 6 (83%) evaluated patients in cohorts 1, 2, 3, and 4, respectively; and CD8(+) T-cell responses were only detected in four patients. Conclusion: In resected and unresectable NSCLC patients and irrespective of whether standard chemotherapy was concurrent or not, MAGE-A3 immunotherapeutic is well tolerated and induces MAGE-A3-specific immune responses.

Changes in Cardiac Substrate Transporters and Metabolic Proteins Mirror the Metabolic Shift in Patients with Aortic Stenosis

In the hypertrophied human heart, fatty acid metabolism is decreased and glucose utilisation is increased. We hypothesized that the sarcolemmal and mitochondrial proteins involved in these key metabolic pathways would mirror these changes, providing a mechanism to account for the modified metabolic flux measured in the human heart. Echocardiography was performed to assess in vivo hypertrophy and aortic valve impairment in patients with aortic stenosis (n = 18). Cardiac biopsies were obtained during valve replacement surgery, and used for western blotting to measure metabolic protein levels. Protein levels of the predominant fatty acid transporter, fatty acid translocase (FAT/CD36) correlated negatively with levels of the glucose transporters, GLUT1 and GLUT4. The decrease in FAT/CD36 was accompanied by decreases in the fatty acid binding proteins, FABPpm and H-FABP, the β-oxidation protein medium chain acyl-coenzyme A dehydrogenase, the Krebs cycle protein α-ketoglutarate dehydrogenase and the oxidative phosphorylation protein ATP synthase. FAT/CD36 and complex I of the electron transport chain were downregulated, whereas the glucose transporter GLUT4 was upregulated with increasing left ventricular mass index, a measure of cardiac hypertrophy. In conclusion, coordinated downregulation of sequential steps involved in fatty acid and oxidative metabolism occur in the human heart, accompanied by upregulation of the glucose transporters. The profile of the substrate transporters and metabolic proteins mirror the metabolic shift from fatty acid to glucose utilisation that occurs in vivo in the human heart

Improved Survival, Vascular Differentiation and Wound Healing Potential of Stem Cells Co-Cultured with Endothelial Cells

In this study, we developed a methodology to improve the survival, vascular differentiation and regenerative potential of umbilical cord blood (UCB)-derived hematopoietic stem cells (CD34+ cells), by co-culturing the stem cells in a 3D fibrin gel with CD34+-derived endothelial cells (ECs). ECs differentiated from CD34+ cells appear to have superior angiogenic properties to fully differentiated ECs, such as human umbilical vein endothelial cells (HUVECs). Our results indicate that the pro-survival effect of CD34+-derived ECs on CD34+ cells is mediated, at least in part, by bioactive factors released from ECs. This effect likely involves the secretion of novel cytokines, including interleukin-17 (IL-17) and interleukin-10 (IL-10), and the activation of the ERK 1/2 pathway in CD34+ cells. We also show that the endothelial differentiation of CD34+ cells in co-culture with CD34+-derived ECs is mediated by a combination of soluble and insoluble factors. The regenerative potential of this co-culture system was demonstrated in a chronic wound diabetic animal model. The co-transplantation of CD34+ cells with CD34+-derived ECs improved the wound healing relatively to controls, by decreasing the inflammatory reaction and increasing the neovascularization of the wound
