Defining root death in studies of root dynamics is problematic because cell death occurs gradually and the resulting effects on root function are not well understood. In this study, metabolic activity of grape roots of different ages was assessed by excised root respiration and tetrazolium chloride reduction. We investigated changes in metabolic activity and patterns of cell death occurring wit...

A diet high in fat induces cardiac hypertrophy, inflammation, and oxidative stress. Although such actions have largely been ascribed to fat deposition, the accumulation of advanced glycation end products (AGEs) and subsequent activation of the receptor for AGEs (RAGE) may also represent important mediators of cardiac injury following exposure to a Western diet. In this study, male C57BL6J and R...

PURPOSE Abnormalities in electroretinograms (ERG), such as reduced amplitudes and delayed implicit times of a- and b-wave and oscillatory potentials (OPs), are one of the earliest features of diabetic retinopathy prior to obvious vascular changes in diabetic retinas. We have previously shown that serum levels of advanced glycation end products (AGEs) are correlated with a delayed latency of OPs...

RICHARD KIECKHEFER, Magic in the Middle Ages, Cambridge Medieval Textbooks, Cambridge University Press, 1989, 8vo, pp. x, 219, illus., £20.00/$39.50, £6.95/$9.95 (paperback). Magic in the Middle Ages is meant to be a general textbook on anything covered by the term "magic"-defined in the most generous sense as a cultural form in Europe between the years c. 500 to 1500. It succeeds admirably. Be...

Ages of extragalactic globular clusters can provide valuable insights into the formation and evolution of galaxies. In this contribution the photometric methods of age dating old globular cluster systems are summarised. The spectroscopic approach is reviewed with an emphasis of the right choice of age diagnostics. We present a new method of quantifying the relatively best age-sensitive spectros...

After open partial laryngectomy (HOPL), many patients experience deterioration of laryngeal function over time. The aim of this study was to evaluate laryngeal functional outcome at least 10 years after surgery in a cohort of 80 elderly patients. The incidence of aspiration pneumonia (AP) and objective/subjective laryngeal functional assessments were carried out. Eight patients experienced AP i...

The objective of this paper is to explain the principles of the design of a coarse space in a simplified way and by pictures. The focus is on ideas rather than on a more historically complete presentation. That can be found, e.g., in [ 28]. Also, space limitation does not allow us even to mention many important methods and papers that should be rightfully included. The coarse space facilitates ...
