  • The perfect cardiac catheterization technique, including good diagnostic and therapeutic qualities, without risk and with no recovery time for the patient, does not exist. Obtaining initial access to the arterial circulation is the first and most frequent catheterization difficulty encountered by the interventional cardiologist during the procedure. Often, it is also the only difficult part of the exam for the patient because it may cause a vagal reaction or painful spasm.

  • Microvascular perfusion is often impaired after primary percutaneous coronary intervention (PCI). We proposed that in situ thrombosis might contribute to poor myocardial perfusion in this setting. To test this hypothesis, we evaluated the effect of lowdose intracoronary streptokinase administered immediately after primary PCI. Methods Forty-one patients undergoing primary PCI were randomly assigned to receive intracoronary streptokinase (250 kU) or no additional therapy.

  • It is only 26 years since the first percutaneous transluminal coronary angioplasty (PTCA) was carried out by the pioneering Swiss radiologist, Andreas Greuntzig, heralding the dawn of interventional cardiology. In this short time, interventional cardiology has overcome many limitations and undergone major evolutionary changes—most notably the development of the coronary stent. Worldwide, many thousands of patients now safely undergo percutaneous coronary intervention every day, and the numbers continue to grow.

  • Several studies have compared outcomes for coronary-artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), but most were done before the availability of stenting, which has revolutionized the latter approach. methods We used New York’s cardiac registries to identify 37,212 patients with multivessel disease who underwent CABG and 22,102 patients with multivessel disease who underwent PCI from January 1, 1997, to December 31, 2000.

  • In its most general form, a distributed event notification service is composed of interconnected servers, each one serving some subset of the clients of the service, as shown in Figure 1. (Some use the terms proxy and broker instead of the term server.) The clients are of two kinds: objects of interest, which are the generators of events, and interested parties, which are the consumers of event notifications. Of course, a client can act as both an object of interest and an interested party.

  • WHO has a long tradition in synthesizing the evidence on health aspects of air quality and in preparing air quality guidelines defining conditions for healthy air. We are grateful to the outstanding scientists conducting this work. We hope that these new guidelines will be useful globally to people assessing indoor air quality with a view to predicting its effects on health, and also to those with responsibil- ity for introducing measures to reduce health risks from indoor exposure to air pollutants.

  • Product evaluation is an important part of brewing, whether performed informally or formally and whether the product is from a commercial or home brewery. Formal beer evaluation serves three primary purposes in the context of brewing competitions. First, the beer evaluations provide feedback to the brewer concerning how well an individual recipe represents its intended beer style. This feedback can be useful as recipes are fine-tuned and attempts are made to improve the beer. Second, beer evaluations may provide brewers with troubleshooting advice.

  • Indoor air pollution poses many challenges to the health pro- fessional. This booklet offers an overview of those challenges, focusing on acute conditions, with patterns that point to par- ticular agents and suggestions for appropriate remedial action. The individual presenting with environmentally associated symptoms is apt to have been exposed to airborne substances originating not outdoors, but indoors. Studies from the United States and Europe show that persons in industrial- ized nations spend more than 90 percent of their time indoors1.

  • The mortality from ischemic heart disease has decreased in recent years. The better under‐ standing of risk factors associated with development of coronary artery disease (CAD) has significantly contributed to this decline. Preventive measures such as aggressive therapy of arterial hypertension, diabetes mellitus, and lipid disorders and by campaigning against the smoking are important components of this medical success.

  • The takeover of toxic assets by the government at zero cost and the corresponding write- down of assets will create transparency, avoid the high expense of pricing distressed assets, and will insure that shareholders are the first ones to bear the cost of failure. 27 The risk of moral hazard will also be effectively limited. A zero-cost acquisition is also justified based on the fact that the active management of the troubled assets is impaired by their complex structure. This approach will also keep the bad bank’s initial capital requirements at a minimum....

  • Governments The U.S. Treasury and state and local governments raise large sums in the money market. The Treasury raises funds in the money market by selling short-term obligations of the U.S. government called Treasury bills. Bills have the largest volume outstanding and the most active secondary market of any money market instrument. Because bills are generally considered to be free of default risk, while other money market instruments have some default risk, bills typically have the lowest interest rate at a given maturity.

  • The most common Internet payment method for the business-to-consumer segment of electronic commerce is credit cards. However, the security of data transmitted over the Internet has been a major concern for customers. At present most companies use SSL (Secure Socket Layer) protocol to provide security and privacy. This protocol provides consumers a means to encrypt their order information. While providing a basic level of security this protocol has been breached and does not enjoy a high level of consumer confidence.

  • One of this study’s aims is to show the large number of variables that have an influence on the socio-economic development of aid recipients. Furthermore, these are variables that donor governments can do something about (to a greater or lesser extent). There are also multiple connections between these variables, so specifying the factors that ultimately have an influence on achieving the MDGs is extremely complex.

  • In patients with stable coronary artery disease, it remains unclear whether an initial management strategy of percutaneous coronary intervention (PCI) with intensive pharmacologic therapy and lifestyle intervention (optimal medical therapy) is superior to optimal medical therapy alone in reducing the risk of cardiovascular events. Methods We conducted a randomized trial involving 2287 patients who had objective evidence of myocardial ischemia and significant coronary artery disease at 50 U.S. and Canadian centers....

  • There are three problems with the above set of reasonings. First, conventional indices of the standard of living pertain to commodity production, not to the natural-resource base onwhich production depends. Statistics on pastmovements ofworld (or regional) income and agricultural production say nothing about this base. They don’t say if increases in GNP per head in a country aren’t being realized by means of a depletion of natural capital (e.g., ecosystem functioning).
