    Tissue perfusion rate determined from the decay of oxygen-15 activity after photon activation in situ (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-06-15
    Description: Rates of cerebral perfusion were obtained from measurements of the disappearance (wash-out) of oxygen-15 after in situ tissue activation with 45-million-volt x-rays. In an anesthetized cat, typical values were 90 milliliters per minute per 100 grams of tissue, with 55 percent wash-out. In a specific radiotherapy patient, the value was 65 milliliters per minute per 100 grams of tissue, with 63 percent wash-out of oxygen-15 through incorporation into tissue water.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hughes, W L -- Nussbaum, G H -- Connolly, R -- Emami, B -- Reilly, P -- New York, N.Y. -- Science. 1979 Jun 15;204(4398):1215-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451567" target="_blank"〉PubMed〈/a〉

    Optical image quality and the cone mosaic (1986)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1986-01-31
    Description: Contrary to the orthodox view that optical image quality should "match" the photoreceptor grain, anatomical data from the eyes of various animals suggest that the image quality is significantly superior to the potential resolution of the cone mosaic in most retinal regions. A new theory is presented to explain the existence of this relation and to better appreciate eye design. It predicts that photoreceptors are potentially visible through the natural optics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Snyder, A W -- Bossomaier, T R -- Hughes, A -- New York, N.Y. -- Science. 1986 Jan 31;231(4737):499-501.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3941914" target="_blank"〉PubMed〈/a〉
