    Notes: In recent publications we have described a novel method of analysis for high-resolution NMR spectra of compounds in isotropic solution which differs from conventional procedures in that it exploits the full information content of a spectrum and does not require assignments of energy levels or transitions. We now present a further development of this technique which also makes it applicable to the NMR spectra of molecules partially oriented in liquid crystal solvents. Illustrative applications are reported for the nematic phase spectra of allyl fluoride, allyl chloride and allyl bromide. The results are discussed in terms of various theoretical models of the interplay between the internal and overall rotations of the conformationally mobile solutes.

    Sex preselection in mammals? Separation of sperm bearing Y and "O" chromosomes in the vole Microtus oregoni (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-11-26
    Description: The two sex determining sperm populations of the vole Microtus oregoni were separated according to DNA content by use of flow sorting instrumentation. Although the sperm were not viable, they should be useful for addressing the question of haploid expression of genes linked to sex chromosomes and for efficiently searching for biochemical markers that differentiate the two populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pinkel, D -- Gledhill, B L -- Lake, S -- Stephenson, D -- Van Dilla, M A -- New York, N.Y. -- Science. 1982 Nov 26;218(4575):904-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6753153" target="_blank"〉PubMed〈/a〉
