This paper reviews the worldwide growth of openaccess (OA) repositories, 2005 to 2012, using data collected by the OpenDOAR project. Initial repository development was focused on North America, Western Europe, and Australasia, particularly the United States, United Kingdom, Germany, and Australia, followed by Japan. Since 2010, there has been repository(More)
Alkaline phosphatase activity has been measured in mucosal scrapings of rat small intestine from birth to weaning. The levels of activity were then compared with those found in brush border fractions and cell residues over the same period. The amount of activity found in the residues was too high and variable to be accounted for in terms of diffusion, and(More)
Electron microscope studies of the distribution of four phosphatases (Alkaline phosphatase, Acid phosphatase, ATP-ase and AMP-ase) have been made on rat jejunum from birth to ten days after weaning. The results showed that a considerable change in the location of alkaline phosphatase occurred in the early stages of post-natal development. Acid phosphatase(More)
Changes in the ultrastructure, and distribution of phosphatases in the intestinal epithelium of Rana temporaria during development were consistent with other developmental changes. Alkaline phosphatase AMP-ase and ATP-ase were always associated with sites of absorption of foodstuffs into the cell. Initially, these were only the yolk platelets but at the(More)
The nature of the myocardial depression observed in patients with septic shock, and in animals late in shock induced by endotoxin, is still under examination. These studies, in cats and kittens administered an LD80 dose of E coli endotoxin, were designed to examine the relationship between changes in myocardial contractility, in cellular electrophysiology(More)
The scanning electron microscope has been used to investigate the surfaces of epidermis, hair follicles, fat cells, glands and blood vessels in sections of human skin. The appearances of structures associated with these surfaces have been described. The results demonstrate that this new instrument can become an important tool in the investigation of surface(More)
Immersion of the intestinal tissue, from rat jejunum, in hypertonic saline produced very rapid changes in all regions of the epithelial cells, but the apical region was apparently unaffected by hypotonic solutions for at least (1/2) hour. In both cases, blistering of the microvilli was taken as the first sign of degenerative changes which finally resulted(More)
