OBJECTIVE The aim was to investigate whether impaired coronary flow reserve associated with cardiac hypertrophy could significantly limit the flow debt repayment following short periods of coronary occlusion and exacerbate or prolong episodes of myocardial ischaemia. METHODS Left ventricular hypertrophy was induced in guinea pigs by aortic constriction and the hearts were isolated six weeks l...

To test the hypothesis that the endothelium-derived relaxing factor (EDRF) contributes to coronary vasodilation induced by myocardial ischemia, we examined the effect of NG-nitro-L-arginine (a potent and selective inhibitor of EDRF release) on the coronary reactive hyperemic response in the open-chest dogs. Intracoronary infusion of NG-nitro-L-arginine at a coronary plasma concentration of 5 x ...

The study presents the issues of rural women in Sadar Upazila of Gazipur district considering their participation in micro credit programs for poverty alleviation. Data were collected from 75 BRAC women beneficiaries of four villages following random sampling techniques. On the basis of credit, the respondent’s have been classified into three categories.

BACKGROUND Borrowing money is a common strategy to cope with health care costs. The impact of borrowing on households can be severe, leading to indebtedness and further impoverishment. However, the available literature on borrowing practices for health is limited. We explore borrowing practices for paying for health care by the poor in Cambodia and provide a typology, associated conditions, and...

Why do countries repay their debts? If countries in default have sufficient opportunities to save, Bulow and Rogoff [6] have shown that the answer cannot stem from a country’s desire to preserve a reputation for repayment. As a result, researchers have explained the existence of sovereign debt by either placing restrictions on the deposit contracts banks can offer, or by looking outside the cre...

We examine the nature of debt contracts when repayment of debt cannot be fully enforced. We study outcomes an infinite-horizon economy in which some individuals have access to a productive, intertemporal technology. Individuals without access to the technology must lend their savings to the rest. Borrowers can default on their debt at any time: lenders can capture a fraction of their investment...

The present study was designed to elucidate the role of collateral development, per se, on reactive hyperemia without persistent coronary stenosis in instrumented conscious dogs. Functional states of coronary collaterals were augmented by repetitive 2 minutes of coronary occlusion every 30 minutes for 2-9 days. Regional shortening measured sonomicrometrically recovered from -1.2 +/- 6.5% of the...

When is it optimal for a government to default on its legal repayment obligations? We answer this question for a small open economy with domestic production risk in which contracting frictions make it optimal for the government to finance itself by issuing non-contingent debt. We show that Ramsey optimal policies occasionally deviate from the legal repayment obligation and repay debt only parti...

Can microfinance borrowers use the discipline of regular loan repayments in order to accumulate savings if prompted to do so? In an experiment, we offered commercial savings products to the microfinance borrowers of Guatemala’s largest public-sector bank. We find that giving these borrowers the opportunity to develop a saving plan and be reminded of saving at the time of loan repayment caused n...
