This series presents studies that have used the paradigm of landscape ecology. Other approaches, both to landscape and landscape ecology are common, but in the last decade landscape ecology has become distinct from its predecessors and its contemporaries. Landscape ecology addresses the relationships among spatial patterns, temporal patterns and ecological processes. The effect of spatial configurations on ecological processes is fundamental. When human activity is an important variable affecting those relationships, landscape ecology includes it. Spatial and temporal scales are as large as...

Twenty-nine presentations from an international congress held in February 1997 on the topic of left ventricular hypertrophy as an important and independent risk factor in cases of hypertension. The first section deals with the structural aspects and mechanisms of LVH. Sections two and three cover th

Left ventricular hypertrophy represents one of the most common complications of the hypertensive state. Indeed, since the Framigham Heart Study, several epidemiological studies have provided clearcut evidence that cardiac hypertrophy represents an important and independent risk factor for the hypertensive patient. Since the introduction of quantitative ultrasound techniques to evaluate cardiac function and state, the research in the field of left ventricular hypertrophy has been par- ticularly active and fruitful, allowing us to gain new information on the pathophysiology of this condition...
