    Notes: Summary Some aspects of the manner in which the central nervous system uses sensory information for the guidance of eye and arm movements were investigated. When subjects experience apparent motion of their restrained forearm, induced by vibration of their biceps muscle in the dark, they are able to pursue with their eyes at least part of this “motion” and to point with their nonvibrated limb to the apparent location of the vibrated arm. The presence of a small target light on the vibrated hand limits the extent of illusory change in limb position and results in illusory motion of the target light in the same direction as the arm motion. When asked to indicate the spatial position of the light or hand, subjects still point with their nonvibrated arm to the apparent locations. Although visual pursuit of the illusory motion of the forearm can still be elicited in the presence of the target light on the hand, the subjects' eyes remain steadily fixating the stationary target light when they are instructed to track its illusory motion. These findings demonstrate that sensory and motor factors affecting the perception of visual direction and the guidance of arm and eye movements can be differentially employed at several levels of central nervous control.

    Precursor keratin protein from human epidermis (1978)

    Notes: Prekeratin has been isolated from human epidermis using the method of Matoltsy for bovine nose epidermis. Analysis by sedimentation equilibrium indicates that human prekeratin is heterogeneous in solution. The molecular weight range is from about 200 × 103 to at least 2 × 106. Polyacrylamide gel electrophoresis shows three polypeptide chains of molecular weights 65,000, 60,000 and 58,000. A lower than average ratio of polar/apolar amino acid residues suggests that hydrophobic interactions are important for stability.

    The role of histidine in human epidermis (1977)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 97 (1977), S. 0

    Notes: Incorporation of radioactively-labelled histidine into half-thickness skin and into the major protein fraction extracted from epidermis by urea (protein Fraction A) has been measured and compared with the amount of labelled urocanic acid appearing in the same specimen.After a short lag period, incorporation into half-thickness skin and into protein Fraction A was foxmd to be linear up to 23 h of the study.Histidine appeared to be initially preferentially deaminated to urocanic acid. The somewhat erratic presence of urocanic acid at later periods is attributed to its high instability and solubility.

    Fibrous proteins of normal and abnormal human epidermis (1979)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 100 (1979), S. 0

    Topics: Medicine
    Notes: Keratin proteins of human epidermis have been isolated from normal and abnormal tissues. The normal proteins whether removed from living layers (prekeratin) or from the stratum corneum (keratin) are shown to consist of three chains, molecular weights 65,000 (A), 60,000 (B) and 52,000 (C). When compared with the epidermal proteins isolated from abnormal tissues, differences can be detected in the electrophoretic pattern of the subunits. In general, relative amounts of the individual chains are altered and in specific cases one or two of the polypeptides found normally are missing. All the α-fibrous proteins extracted are found to be very similar in amino acid composition.

    A test of the equivalence principle using a space-borne clock (1979)
    Springer
    General relativity and gravitation 10 (1979), S. 181-204

    Notes: Abstract An experimental verification of Einstein's equivalence principle has been made using an atomic hydrogen maser in a space probe attaining an altitude of 10,000 km above the earth's surface. At the present stage of the data reduction, confirmation is at the 2×10−4 level of accuracy. The experiment and the resulting data are described including a comment on the limits to the anisotropy of the velocity of light. We believe that this is the first direct, high-accuracy test of the symmetry of the propagation of light and a beginning in the use of high-accuracy clocks in space to measure relativistic phenomena.
