This paper examines how a shock to collateral value, caused by asset market fluctuations, influences the debt capacities and investments of firms. Using a source of exogenous variation in collateral value provided by the land market collapse in Japan, I find a large impact of collateral on the corporate investments of a large sample of manufacturing firms. For every 10 percent drop in collatera...

OBJECTIVE We attempted to investigate the potential association between leptin and coronary collateral vessel development in patients with non-ST elevation acute coronary syndromes (NSTE-ACS). METHODS One hundred and nineteen consecutive patients with NSTE-ACS with high-grade coronary stenosis or occlusion in at least one epicardial coronary artery were prospectively enrolled in a cross-secti...

This study was performed to test the hypothesis that active constriction of coronary collateral vessels can worsen hypoperfusion of collateral-dependent myocardium during exercise. Studies were performed in seven adult mongrel dogs in which intermittent followed by permanent occlusion of the left circumflex coronary artery produced an area of collateral-dependent myocardium without gross eviden...

Collateral status is an independent predictor of stroke outcome. However, the spatiotemporal manner in which collateral flow maintains cerebral perfusion during cerebral ischemia is poorly understood. Diabetes exacerbates ischemic brain damage, although the impact of diabetes on collateral dynamics remains to be established. Using Doppler optical coherent tomography, a robust recruitment of lep...

BACKGROUND The evaluation of new therapeutic modalities to induce collateral growth in coronary artery disease require improved methods of angiographic characterization of collaterals, which should be validated by quantitative assessment of collateral function. METHODS AND RESULTS In 100 patients with total chronic occlusion of a major coronary artery (duration >2 weeks) collaterals were asse...

We show that cross-border financial flows arise when countries differ in their abilities to use assets as collateral. Financial integration is a way of sharing scarce collateral. The ability of one country to leverage and tranche assets provides attractive financial contracts to investors in the other country, and general equilibrium effects on prices create opportunities for investors in the f...

The effect of chronic coronary arterial narrowing on the coronary collateral circulation has been studied in rested and exercised dogs. The data indicate that moderate and severe arterial narrowing results in extensive collateral development proportional to the degree of narrowing, further that exercise leads to even greater anastomoses. The results also show that while mild arterial narrowing ...

Background: A study was undertaken to assess the prevalence of interlobar collateral ventilation in patients with severe emphysema to identify factors that may help to predict patients with significant collateral ventilation. Methods: Between April 2002 and August 2003, ex vivo assessment of the lungs 17 consecutive patients with smoking related severe emphysema was performed. To assess collate...
