    Description / Table of Contents: Thin Layer Chromatography of Chloro-Cyclophosphazenes. II. Separation of Chloro-Cyclophosphazenes (NPCl2)n (n=3-15)Thin layer chromatography on silica gel was used for separation of higher members of homologic series of Chloro-Cyclophosphazenes. Under the indicated conditions spots of 13 substances with help of new and selective detection reagents were located. The Rf values of the substance were mathematically worked up and the probable influences that enables the separation were discussed.
    Notes: Dünnschichtchromatographie auf Silicagel wurde zur Trennung der höheren Glieder der homologen Reihe von Chloro-Cyclophosphazenen benutzt. Unter den beschriebenen Arbeitsbedingungen wurden Flecke von 13 Stoffen mit neuen empfindlichen und selektiven Nachweisverfahren ermittelt. Die Rf-Werte wurden mathematisch bearbeitet, und die wahrscheinlichen Einflusse, die die Trennung ermöglichen, wurden diskutiert.

    Description / Table of Contents: Thin Layer Chromatography of Chloro-Cyclophosphazenes I. Separation of Oligomers [MNCL2]n (n = 3 - 7)This paper presents a separation study of cyclo-chlorophosphazenes by means of thin layer chromatography on silica gel and a new sensitive method of detection of these separated substances. The chromatographic behavior of oligomers (n = 3-7) of the homologic series [NPCL2]n was experimentally studied. The Rf values of the substances were correlated with their molecular weights. As a result a Quasi-linear function was obtained for the members with n = 4-7.
    Notes: Es wurde eine Methode zur selektiven Trennung der Chlorocyclophosphazene mittels Dünnschichtchromatographie auf Silicagel und ein neues Nachweisverfahren für diesen Verbindungstyp ausgearbeitet. Experimentell wurden die Glieder der homologen Reihe [NPCL2]n bis zum Cyclo-Heptaphosphazaheptaendekaterachlorid Getrennt. Die Rf-Werte der Homologen [NPCL2]n bis [NPCL2]7 besitzen, in Abhängigkeit von der Anzahl der Phosphoratome, einen Quasi-Linearen Verlauf.

    Skeletal muscle: length-dependent effects of potentiating agents (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-10-02
    Description: The ability of vertebrae skeletal muscle to contract more vigorously than normal in the presence of potentiating agents depends on the initial length of a muscle cell. Other factors such as the intracellular calcium ion transient, temperature, chemical nature of the potentiating agent, and the ratio of intrinsic twitch to tetanic force influence the degree of contractile potentiation but cannot account for the length dependence. At least part of a muscle cell seems normally less than fully active during contractions not only at short lengths but also at optimal sarcomere lengths.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lopez, J R -- Wanek, L A -- Taylor, S R -- NS 14268/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Oct 2;214(4516):79-82.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6974399" target="_blank"〉PubMed〈/a〉
