    On potentials and relevance of the use of copulatory structures in anostracan taxonomy (1997)
    Springer
    Hydrobiologia 359 (1997), S. 83-92 
    Details
    ISSN: 1573-5117
    Schlagwort(e): Branchiopoda ; Anostraca ; genital morphology ; genus concept

    Thema: Biologie
    Notizen: Abstract This paper reviews and extends the knowledge of anostracan penile morphology and its taxonomic significance. Since Linder‘s pioneering classification(based partly on male genital characters), the morphology of both basal and distal penile parts has been applied repeatedly to reorganize or establish higher anostracan taxa, or to extend their diagnoses. In general, the configuration of both basal and distal penile structures follows a constant pattern in well-defined genera. Size and shape of processes and spinulation on the basal (in Linderiella and Chirocephalidae) and the distal parts (in Parartemia), however, may show inter-specific differences. Variability in penile structures in the current genus Brachinella indicates the need for a taxonomic revision of this genus. Similar intra-generic penis morphology may contribute to hybridizability of congeners and validate Dubois‘genus concept for use in anostracans.

    Supplement to "Checklist of the Anostraca" (1997)
    Springer
    Hydrobiologia 359 (1997), S. 243-245 
    Details
    ISSN: 1573-5117
    Schlagwort(e): Anostraca ; checklist
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Our 1995 "Checklist of the Anostraca" covered all species described through 31 December 1993 along with those described in the volume from the Second International Large Branchiopod Symposium (Hydrobiologia 298). This supplement includes new species (14) described through 31 December 1996, one change in rank and one new species discussed in this symposium volume, anew synonym, and correction of errors discovered in the original. We do not update new range extensions. With these additions and changes, we number the named anostracan fauna of the world at 273 species and six subspecies organized in 23 genera. The need for more study of anostracan zoogeography is again demonstrated by the fact that seven of the 16 species added to the checklist are know only from their type localities. Until we have more complete information on the distributions of the species, it will not be possible to make an accurate evaluation of the status of anostracan biodiversity.

    Anostracans in dark sections of Saudi Arabian caves (1997)
    Springer
    Hydrobiologia 359 (1997), S. 203-206 
    Details
    ISSN: 1573-5117
    Schlagwort(e): Anostraca ; cave ; Saudi Arabia
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Anostracans were found living in ephemeral pools in the dark sections of three caves on the As Summan Plateau in Saudi Arabia. Branchipus schaefferi Fischer, 1834 occurred alone in one while it cohabited with Streptocephalus torvicornisbucheti Daday, 1910 in a second cave; fairy shrimps were observed but not collected from the third. None of the specimens demonstrated any of the types of morphological changes typically associated with cave adapted species. This is likely due to continuing colonization of the pools during flooding events.

    G-protein-independent coupling of MC4R to Kir7.1 in hypothalamic neurons (2015)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2015-01-21
    Beschreibung: The regulated release of anorexigenic alpha-melanocyte stimulating hormone (alpha-MSH) and orexigenic Agouti-related protein (AgRP) from discrete hypothalamic arcuate neurons onto common target sites in the central nervous system has a fundamental role in the regulation of energy homeostasis. Both peptides bind with high affinity to the melanocortin-4 receptor (MC4R); existing data show that alpha-MSH is an agonist that couples the receptor to the Galphas signalling pathway, while AgRP binds competitively to block alpha-MSH binding and blocks the constitutive activity mediated by the ligand-mimetic amino-terminal domain of the receptor. Here we show that, in mice, regulation of firing activity of neurons from the paraventricular nucleus of the hypothalamus (PVN) by alpha-MSH and AgRP can be mediated independently of Galphas signalling by ligand-induced coupling of MC4R to closure of inwardly rectifying potassium channel, Kir7.1. Furthermore, AgRP is a biased agonist that hyperpolarizes neurons by binding to MC4R and opening Kir7.1, independently of its inhibition of alpha-MSH binding. Consequently, Kir7.1 signalling appears to be central to melanocortin-mediated regulation of energy homeostasis within the PVN. Coupling of MC4R to Kir7.1 may explain unusual aspects of the control of energy homeostasis by melanocortin signalling, including the gene dosage effect of MC4R and the sustained effects of AgRP on food intake.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383680/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383680/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghamari-Langroudi, Masoud -- Digby, Gregory J -- Sebag, Julien A -- Millhauser, Glenn L -- Palomino, Rafael -- Matthews, Robert -- Gillyard, Taneisha -- Panaro, Brandon L -- Tough, Iain R -- Cox, Helen M -- Denton, Jerod S -- Cone, Roger D -- 5R01 DK082884-03/DK/NIDDK NIH HHS/ -- DK020593/DK/NIDDK NIH HHS/ -- F31 DK102343/DK/NIDDK NIH HHS/ -- P30 DK020593/DK/NIDDK NIH HHS/ -- R01 DK064265/DK/NIDDK NIH HHS/ -- R01 DK070332/DK/NIDDK NIH HHS/ -- R01DK064265/DK/NIDDK NIH HHS/ -- R01DK070332/DK/NIDDK NIH HHS/ -- R25 GM059994/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Apr 2;520(7545):94-8. doi: 10.1038/nature14051.

    Mutations in the dystrophin-associated protein gamma-sarcoglycan in chromosome 13 muscular dystrophy (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1995-11-03
    Beschreibung: Severe childhood autosomal recessive muscular dystrophy (SCARMD) is a progressive muscle-wasting disorder common in North Africa that segregates with microsatellite markers at chromosome 13q12. Here, it is shown that a mutation in the gene encoding the 35-kilodalton dystrophin-associated glycoprotein, gamma-sarcoglycan, is likely to be the primary genetic defect in this disorder. The human gamma-sarcoglycan gene was mapped to chromosome 13q12, and deletions that alter its reading frame were identified in three families and one of four sporadic cases of SCARMD. These mutations not only affect gamma-sarcoglycan but also disrupt the integrity of the entire sarcoglycan complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noguchi, S -- McNally, E M -- Ben Othmane, K -- Hagiwara, Y -- Mizuno, Y -- Yoshida, M -- Yamamoto, H -- Bonnemann, C G -- Gussoni, E -- Denton, P H -- Kyriakides, T -- Middleton, L -- Hentati, F -- Ben Hamida, M -- Nonaka, I -- Vance, J M -- Kunkel, L M -- Ozawa, E -- NS23740/NS/NINDS NIH HHS/ -- P01-NS26630/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1995 Nov 3;270(5237):819-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Neuroscience, National Center for Neurology and Psychiatry, Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7481775" target="_blank"〉PubMed〈/a〉
