Organic nitrates are commonly used in angina pectoris and ischemic cardiomyopathy. In order to optimize their effectiveness and patient convenience, several aspects must be observed. Adequate doses, suitable dosage forms and asymmetric pattern of usage to prevent the nitrate tolerance are some factors that a physician must be familiar with. The objective of the present study was to define the p...
TO THE EDITOR: The letter of Lundberg et al. (12) does not relate directly to any of the articles we published in this journal (1, 2, 6). Rather, the correspondents make a general point on the potential risks to athletes who might choose to supplement their diet with nitrate or (especially) nitrite salts with the purpose of reducing the O2 cost of exercise and enhancing exercise tolerance. This...
Large benthic foraminifera (LBF) are important for reef sediment formation, but sensitive to elevated temperature and nutrients. However, it is possible that conspecific foraminifera living in different reef sites present divergent response to environmental shifts. We investigated how populations of Amphistegina lobifera from reef sites located along a temperature and nutrient gradient of the n...
Coral reefs are found within a limited range of environmental conditions or tolerance limits. Estimating these limits is a critical prerequisite for understanding the impacts of climate change on the biogeography of coral reefs. Here we used the diagnostic model ReefHab to determine the current environmental tolerance limits for coral reefs and the global distribution of potential coral reef ha...
