takotsubo cardiomiopathy after acute diarrhea
2010
Takotsubo cardiomyopaty is a recently described syndrome characterized by transient left ventricular dysfunction, mimicking an acute coronary syndrome and usually precipitated by a physical or emotional stress. We report the first case of Takotsubo cardiomyopathy after acute diarrhea in a man. It may be argued that severe diarrhea in predisposed individuals may cause an acute stress resulting in increased sympathetic activity leading to this syndrome. Probably the relationship between the adrenergic system and the heart is more complex than general thought and the stimuli which favor an autonomic imbalance and precipitate the syndrome are very disparate in clinical practice.
Testing for external sustainability under a monetary integration process. Does the Lawson doctrine apply to Europe?
2015
Monetary integration, and more specifically, the creation of a monetary union in Europe, raises new economic questions concerning its functioning and governance. In particular, we focus on the implications of high and persistent current account deficits for the economic performance of monetary union members in the medium term. Recent literature has argued that conventional measures of external sustainability are misleading because they omit the effects of capital variations on net foreign asset positions due to, among others, stock or debt market crises. In this paper we revisit external sustainability making use of the database developed by Lane and Milesi-Ferretti (2007) that includes the…
Labor and product market reforms and external Imbalances: Evidence from advanced economies
2021
We explore the impact of major labor and product market reforms on current account dynamics using a new “narrative” database of major changes in employment protection for regular workers and product market regulation for non-manufacturing industries covering 26 advanced economies over the past four decades. Our main finding is that product market deregulation is associated with a weakening of the current account, while labor market deregulation is associated with an improvement. These effects are transitory and driven by both saving and investment responses. Labor and product market reforms both have a more positive impact on the current account balance when implemented under weak macroecon…
Cross-country variation in patience, persistent current account imbalances and the external wealth of nations
2022
This paper is the first to utilize large-scale international surveys on economic preferences to examine the long-run relationships between patience, current accounts and external wealth. We find robust empirical evidence that countries with more patient individuals tend to run persistent current account surpluses, which in turn result in the accumulation of foreign assets. This theoretically plausible but empirically unexplored relationship holds true for euro area current account imbalances, global current account imbalances and net foreign asset positions worldwide. While the existing current account literature concentrates on proximate macroeconomic determinants, this paper’s extension o…
Diagnosis of mechanical unbalance for double cage induction motor load in time-varying conditions based on motor vibration signature analysis
2013
This paper investigates the detectability of mechanical unbalance in double cage induction motor load using motor vibration signature analysis technique. Rotor imbalances induce specific harmonic components in electrical, electromagnetical, and mechanical quantities. Harmonic components characteristic of this category of rotor faults, issued from vibration signals analysis, are closely related to rotating speed of the rotor, which complicates its detection under non-stationary operating conditions of the motor. Firstly, experimental results were performed first under healthy and mechanical load unbalance cases, for different load levels under steady-state operating conditions to evaluate th…
Comparison of conventional hamstring/quadriceps ratio between genders in level-matched soccer players
2017
Abstract Objectives: The main goal of our study is to compare the hamstring/quadriceps (H/Q) ratio at different knee angles between level-matched male and female soccer players and to determine whether differences in the H/Q ratio exist between the dominant and the non-dominant leg. Methods: A cross-sectional study design was used to compare an isometric H/Q ratio and functional isokinetic ratio (between hamstring in eccentric contraction and quadriceps in concentric contraction) between males (n = 14) and females (n = 14). These ratios were studied at two different speeds of movement (60° s−1 and 180° s−1) and in five different positions (40°, 50°, 60°, 70° and 80° degrees of knee flexion)…
Holes in the Dike: the global savings glut, U.S. house prices and the long shadow of banking deregulation
2015
We explore empirically how capital inflows into the US and financial deregulation within the United States interacted in driving the run-up (and subsequent decline) in US housing prices over the period 1990-2010. To obtain an ex ante measure of financial liberalization, we focus on the history of interstate-banking deregulation during the 1980s, i.e. prior to the large net capital inflows into the US from China and other emerging economies. Our results suggest a long shadow of deregulation: in states that opened their banking markets to out-of-state banks earlier, house prices were more sensitive to capital inflows. We provide evidence that global imbalances were a major positive funding sh…
Assessing Long-Term Fiscal Developments: A New Approach
2009
We use a new approach to assess long-term fiscal developments. By analyzing the time-varying behaviour of the two components of government spending and revenue - responsiveness and persistence - we are able to infer about the sources of fiscal behaviour. Drawing on quarterly data we estimate recursively these components within a system of government revenue and spending equations using a Three-Stage Least Square method. In this way we track fiscal developments, i.e. possible fiscal deteriorations and/or improvements for eight European Union countries plus the US. Results suggest that positions have not significantly changed for Finland, France, Germany, Spain, the United Kingdom and the US,…
Effects of BRCA2 cis-regulation in normal breast and cancer risk amongst BRCA2 mutation carriers
2012
Introduction: Cis-acting regulatory single nucleotide polymorphisms (SNPs) at specific loci may modulate penetrance of germline mutations at the same loci by introducing different levels of expression of the wild-type allele. We have previously reported that BRCA2 shows differential allelic expression and we hypothesize that the known variable penetrance of BRCA2 mutations might be associated with this mechanism. Methods: We combined haplotype analysis and differential allelic expression of BRCA2 in breast tissue to identify expression haplotypes and candidate cis-regulatory variants. These candidate variants underwent selection based on in silico predictions for regulatory potential and di…
