  1. [A study of the process of supplying pigment to the hair in lambs of various breeds and genotypes].

    Doklady Akademii nauk SSSR 308(5):1228 (1989) PMID 2612348

  2. Reduction mechanism of L-cysteine on keratin fibers using microspectrophotometry and Raman spectroscopy.

    Biopolymers 79(6):324 (2005) PMID 16130128

    We concluded that the free amino groups of Cys electrostatically interacted with the anionic ions of the fiber surface, thereby decreasing the reaction rate (the disconnection of -SS- groups) of Cys at pH 9.0. (c) 2005 Wiley Periodicals, Inc....
  3. The agouti gene product inhibits lipolysis in human adipocytes via a Ca2+-dependent mechanism.

    FASEB Journal 12(13):1391 (1998) PMID 9761782

    We have shown recombinant agouti protein to increase adipocyte intracellular Ca2+([Ca2+]i) and thereby stimulate lipogenesis. However, since recent data demonstrate that increasing adipocyte [Ca2+]i may also inhibit lipolysis, we have investigated the role of agouti-induced [Ca2+]i increases in regu...
  4. Microphthalmia: a morphogenetic lethal mutation of the campbelli hamster (Phodopus campbelli).

    Journal of Heredity 89(1):93 (1998) PMID 9487680

    Microphthalmia is a new mutation of the campbelli hamster (Phodopus campbelli) that is controlled by an incomplete dominant autosomal gene Mi. The dorsal coat of the heterozygote had dark markings on a white background. The dark markings appear on the head, back, and rump. Their color is very simila...
  5. Discrete thalamic lesions attenuate winter adaptations and increase body weight.

    American Journal of Physiology -- Legacy Content 273(1 Pt 2):R226 (1997) PMID 9249554

    The midline thalamus (e.g., the paraventricular thalamic nuclei and the reuniens nucleus) of Siberian hamsters and other mammals has been reported to contain specific binding sites for melatonin, a hormone that is essential for photoperiodically induced winter adaptations such as reproductive quiesc...
  6. Why Danes are smug: comparative study of life satisfaction in the European Union.

    British Medical Journal (Abstracts) 333(7582):1289 (2006) PMID 17185710 PMCID 1761170

  7. High polymorphism at the human melanocortin 1 receptor locus.

    Genetics 151(4):1547 (1999) PMID 10101176 PMCID 1460552

    We have sequenced the MC1R gene in 121 individuals sampled from world populations with an emphasis on Asian populations. We found variation at five nonsynonymous sites (resulting in the variants Arg67Gln, Asp84Glu, Val92Met, Arg151Cys, and Arg163Gln), but at only one synonymous site (A942G). Interes...
  8. Production of chimeric pigs and the analysis of chimerism using mitochondrial deoxyribonucleic acid as a cell marker.

    Biology of Reproduction 51(6):1069 (1994) PMID 7888485

    Two injection methods were examined for making chimeras between Chinese pigs (Meishan) and European pigs (Landrace or Landrace x Large White). Furthermore, mitochondrial DNA (mtDNA) polymorphism was detected as a cell marker for the analysis of chimerism. In the first experiment, blastomeres were tr...
  9. The embryology and development of human scalp hair.

    Clinics in Dermatology 6(4):1 (1988) PMID 3063365

    In summary, without a basic knowledge of embryology and development of human hair many abnormalities that occur in early postnatal life cannot be classified. Classification of abnormalities is necessary if specific genetic or biochemical causes are to be looked for and prognosis and genetic counseli...
  10. Mutagenicity of 1,2-dibromo-3-chloropropane (DBCP) in the mouse spot test.

    Mutation Research/Fundamental and Molecular Mec... 174(2):145 (1986) PMID 3713732

    The spot test with 1,2-dibromo-3-chloropropane (DBCP) was carried out using male PW and female C57BL/6 mice. DBCP induced recessive colour spots in offspring with a significantly high frequency of 2.9%, showing that this chemical is mutagenic for somatic cells of mice in vivo.
