    Multiple representations of pain in human cerebral cortex (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-03-15
    Description: The representation of pain in the cerebral cortex is less well understood than that of any other sensory system. However, with the use of magnetic resonance imaging and positron emission tomography in humans, it has now been demonstrated that painful heat causes significant activation of the contralateral anterior cingulate, secondary somatosensory, and primary somatosensory cortices. This contrasts with the predominant activation of primary somatosensory cortex caused by vibrotactile stimuli in similar experiments. Furthermore, the unilateral cingulate activation indicates that this forebrain area, thought to regulate emotions, contains an unexpectedly specific representation of pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Talbot, J D -- Marrett, S -- Evans, A C -- Meyer, E -- Bushnell, M C -- Duncan, G H -- New York, N.Y. -- Science. 1991 Mar 15;251(4999):1355-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de neurophysiologie comportementale, Faculte de medecine dentaire, Universite de Montreal, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2003220" target="_blank"〉PubMed〈/a〉

    Lateralization of phonetic and pitch discrimination in speech processing (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-08
    Description: Cerebral activation was measured with positron emission tomography in ten human volunteers. The primary auditory cortex showed increased activity in response to noise bursts, whereas acoustically matched speech syllables activated secondary auditory cortices bilaterally. Instructions to make judgments about different attributes of the same speech signal resulted in activation of specific lateralized neural systems. Discrimination of phonetic structure led to increased activity in part of Broca's area of the left hemisphere, suggesting a role for articulatory recoding in phonetic perception. Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zatorre, R J -- Evans, A C -- Meyer, E -- Gjedde, A -- New York, N.Y. -- Science. 1992 May 8;256(5058):846-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉McConnell Brain Imaging Centre, Montreal Neurological Institute, McGill University, Quebec, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589767" target="_blank"〉PubMed〈/a〉

    Assignment of a locus for familial melanoma, MLM, to chromosome 9p13-p22 (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-11-13
    Description: Linkage analysis of ten Utah kindreds and one Texas kindred with multiple cases of cutaneous malignant melanoma (CMM) provided evidence that a locus for familial melanoma susceptibility is in the chromosomal region 9p13-p22. The genetic markers analyzed reside in a candidate region on chromosome 9p21, previously implicated by the presence of homozygous deletions in melanoma tumors and by the presence of a germline deletion in an individual with eight independent melanomas. Multipoint linkage analysis was performed between the familial melanoma susceptibility locus (MLM) and two short tandem repeat markers, D9S126 and the interferon-alpha (IFNA) gene, which reside in the region of somatic loss in melanoma tumors. An analysis incorporating a partially penetrant dominant melanoma susceptibility locus places MLM near IFNA and D9S126 with a maximum location score of 12.71. Therefore, the region frequently deleted in melanoma tumors on 9p21 presumably contains a locus that plays a critical role in predisposition to familial melanoma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cannon-Albright, L A -- Goldgar, D E -- Meyer, L J -- Lewis, C M -- Anderson, D E -- Fountain, J W -- Hegi, M E -- Wiseman, R W -- Petty, E M -- Bale, A E -- CA 42014/CA/NCI NIH HHS/ -- CA 48711/CA/NCI NIH HHS/ -- RR 00064/RR/NCRR NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 Nov 13;258(5085):1148-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Utah School of Medicine, Salt Lake City 84132.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439824" target="_blank"〉PubMed〈/a〉

    Expression of two T cell receptor alpha chains: dual receptor T cells (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-15
    Description: Although many T cells carry two in-frame V alpha rearrangements, the products of both V alpha rearrangements have never been shown simultaneously on the surface of normal cells. With the use of monoclonal antibodies to V alpha 2, V alpha 12, and V alpha 24, up to one-third of mature T cells expressed two V alpha chains as part of two functional and independent T cell receptors (TCRs). Thus, the "one cell, one receptor" rule does not apply to a large subset of alpha beta T cells. Cells that belong to this dual TCR subset may be specific for a broader range of antigens than cells with a single receptor, which may be important for autoimmunity and alloreactivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Padovan, E -- Casorati, G -- Dellabona, P -- Meyer, S -- Brockhaus, M -- Lanzavecchia, A -- New York, N.Y. -- Science. 1993 Oct 15;262(5132):422-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Basel Institute for Immunology, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8211163" target="_blank"〉PubMed〈/a〉

    Effects of prenatal sex hormones on gender-related behavior (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-03-20
    Description: Gender identity depends largely on postnatal environmental influences, while sex-dimorphic behavior and temperamental sex differences appear to be modified by prenatal sex hormones. A role of the prenatal endocrine milieu in the development of erotic partner preference, as in hetero-, homo-, or bisexual orientation, or of cognitive sex differences has not been conclusively demonstrated.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ehrhardt, A A -- Meyer-Bahlburg, H F -- New York, N.Y. -- Science. 1981 Mar 20;211(4488):1312-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7209510" target="_blank"〉PubMed〈/a〉

    Myelinated nociceptive afferents account for the hyperalgesia that follows a burn to the hand (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-09-25
    Description: Monkeys and human subjects were exposed to a series of thermal stimuli before and after a 53 degrees C, 30-second burn to the glabrous skin of the hand. The responses of C- and A-fiber nociceptive afferents in the monkeys and subjective responses by the humans were compared. The burn resulted in increased sensitivity of the A fibers, decreased sensitivity of the C fibers, and increased pain sensibility (hyperalgesia) in the human subjects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, R A -- Campbell, J N -- NS-00519/NS/NINDS NIH HHS/ -- NS-14447/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1981 Sep 25;213(4515):1527-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7280675" target="_blank"〉PubMed〈/a〉

    Breast imaging in coronal planes with simultaneous pulse echo and transmission ultrasound (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-04
    Description: Clear delineation of breast architecture was achieved with compound pulse echo ultrasound imaging in which the images were acquired in the coronal planes used for quantitative transmission ultrasonic computed tomography. Since most connective tissue planes in the breast radiate toward the nipple, compound scans from the sides of the breast record normal interfaces more consistently and reveal greater symmetries in normal portions of relatively full breasts than do conventional scans in sagittal or transverse planes. Simultaneous acquisition of the pulse echo images and images representing the local ultrasound attenuation coefficient and speed of ultrasound suggested complementary role for reflection and through-transmission images in breast cancer detection. The high quality of pulse echo images in coronal planes provides the potential for more complete pulse echo diagnosis and the basis for spatial correlation of lesions viewed in pulse echo and ultrasonic computed tomograms. These observations may permit routine ultrasonic computed tomography of the breast in the clinical setting.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carson, P L -- Meyer, C R -- Scherzinger, A L -- Oughton, T V -- R01 CA 25323/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1981 Dec 4;214(4525):1141-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7302585" target="_blank"〉PubMed〈/a〉

    Small nuclear RNA U2 is base-paired to heterogeneous nuclear RNA (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-07-30
    Description: Eukaryotic cells contain a set of low molecular weight nuclear RNA's. One of the more abundant of these is termed U2 RNA. The possibility that U2 RNA is hydrogen-bonded to complementary sequences in other nuclear RNA's was investigated. Cultured human (HeLa) cells were treated with a psoralen derivative that cross-links RNA chains that are base-paired with one another. High molecular weight heterogeneous nuclear RNA was isolated under denaturing conditions, and the psoralen cross-links were reversed. Electrophoresis of the released RNA and hybridization with a human cloned U2 DNA probe revealed that U2 is hydrogen-bonded to complementary sequences in heterogeneous nuclear RNA in vivo. In contrast, U2 RNA is not base-paired with nucleolar RNA, which contains the precursors of ribosomal RNA. The results suggest that U2 RNA participates in messenger RNA processing in the nucleus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calvet, J P -- Meyer, L M -- Pederson, T -- GM 21595/GM/NIGMS NIH HHS/ -- GM 27265/GM/NIGMS NIH HHS/ -- P30 12708/PHS HHS/ -- New York, N.Y. -- Science. 1982 Jul 30;217(4558):456-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6178162" target="_blank"〉PubMed〈/a〉
