Data derived from both pronuclear transplantation experiments and classical genetic experiments indicate that the maternal and paternal genetic contributions to the mammalian zygote nucleus do not function equivalently during subsequent development. These observations have been interpreted as resulting from differential 'genome imprinting' during male and female gametogenesis. The molecular mechanism responsible for genome imprinting is unknown, but data gathered to date require that the mechanism fulfill at least four criteria: (1) the imprint must be physically linked to the pronucleus; (2) the imprint must persist through DNA replication and cell division; (3) the mechanism must be capable of affecting gene expression; and (4) the mechanism must be capable of switching the identity of the imprint from one sex to the other in successive generations. One molecular mechanism which could satisfy the first three criteria is differential DNA methylation during gametogenesis itself, or before formation of the zygote nucleus during embryogenesis. We present data indicating that the methylation patterns of exogenous DNA sequences in transgenic mice can be changed by switching their gamete of origin in successive generations. These data suggest that DNA methylation can also satisfy the fourth criterion for an imprinting mechanism. [less ▲]

Exogenous arachidonic acid (10(-8) to 10(-4) M) contracted epithelium-free guinea pig tracheal strips. Intact tracheal strips were contracted slightly by low concentrations of arachidonic acid (10(-8) to 10(-5) M), but higher concentrations relaxed them. In contrast, when tracheal strips were precontracted with histamine or carbachol, exogenous arachidonic acid had no effect on epithelium-free preparations but induced concentration-dependent (10(-8) to 10(-4) M) relaxation of intact tracheal strips. The effects of arachidonic acid both in epithelium-free and epithelium-containing trachea were blocked by either indomethacin (10(-6) M) or aspirin (10(-4) M). Studies on the effects of exogenous arachidonic acid, performed with a "sandwich protocol," demonstrated that the postulated airway epithelium-dependent relaxant factor released by an intact tracheal strip relaxes an adjacent epithelium-free strip in the same organ bath. This relaxation is antagonized by indomethacin suggesting the involvement of a cyclooxygenase product in this phenomenon. Comparison of concentration-response curves for contractile agonists in epithelium-free preparations and in one containing epithelium suggests the mobilization of airway epithelium-dependent relaxant factor by histamine but not by carbachol. The effects of cyclooxygenase and lipoxygenase inhibitors indicated that both relaxant and contractile arachidonic acid metabolites are generated by epithelial and nonepithelial cells alike in response to contractile agonists.

Atmospheric mass loads and deforms the Earth's crust. By performing a convolution sum between daily global barometric pressure data and mass loading Green's functions, we estimate the time dependent effects of atmospheric loading, including those associated with short-term synoptic storms, on surface point positioning measurements and surface gravity observations. We calculate the response of both an oceanless Earth and an Earth with an inverted barometer ocean. Peak to peak vertical displacements are frequently 15-20 mm with accompanying gravity perturbations of 3-6 microgal. Baseline changes can be as large as 20 mm or more. The perturbations are largest at higher latitudes and during winter months. These amplitudes are consistent with the results f Rabbel and Zschau (1985) who modeled synoptic pressure disturbances as Gaussian functions of radius about a central point. Deformation can be adequately computes using real pressure data from points within about 1000 km of the station. Knowledge of local pressure alone, is not sufficient. Rabbel and Zschau's hypothesized corrections for these displacements, which use local pressure and regionally averaged pressure, prove accurate at points well inland but are, in general, inadequate within a few hundred kilometers of the coast.

Die Rolle von kausalen Zuschreibungen und Kontrollwahrnehmungen bei der Bewältigung von chronischen Krankheiten wird untersucht. In einer Stichprobe von 97 Krebspatienten und 39 Herzinfarktpatienten wurden Attributionsstil, Attributionen in Bezug auf den Beginn der Krankheit, wahrgenommene Kontrolle über krankheitsbezogene Veränderungen und depressive Symptome mit Hilfe von Fragebögen erfasst ("Attributional Style Questionnaire" von Peterson und Mitarbeitern, deutsche Version der "Beck Hopelessness-Scale", "Self-Esteem Scale" von Rosenberg sowie eigens entwickelte Skalen). Wesentliche Ergebnisse waren: (1) Der Attributionsstil und die kausalen Attributionen in bezug auf den Beginn der Krankheit stimmten lediglich bezüglich der Dimension "Wahrgenommene Globalität kausaler Faktoren" überein, nicht jedoch bezüglich der Faktoren "Stabilität" und "Internalität". (2) Kausale Zuschreibungen in bezug auf den Beginn der Krankheit waren von depressiven Symptomen wie Hilflosigkeit und Selbstwertgefühl unabhängig. (3) Ein Zusammenhang zwischen Attributionsstil und depressiven Symptomen bestand lediglich bezüglich der Attributionsdimension "Globalität". (4) Die wahrgenommene aktuelle Kontrolle und die erwartete Kontrolle über krankheitsbedingte Folgen hingen stark mit depressiven Symptomen zusammen. (5) Das Alter war von allen Maßen individueller Wahrnehmungen und Attributionen unabhängig. Mit Zunahme der Zeit, die seit der Diagnose verstrichen war, wurden jedoch kausale Faktoren zunehmend external attribuiert. Diese Befunde werden im Kontext einer für notwendig gehaltenen Modifikation des Paradigmas der gelernten Hilflosigkeit diskutiert. [less ▲]

This paper develops a stylized macroeconomic rationing (or disequilibrium) model where the three well-known regimes of Keynesian Unemployment, Classical Unemployment and Repressed Inflation’ are explicitly distinguished and wherein prices and the capital stock are endogenously determined by profit maximizing firms. The framework is one of monopolistic competition. The macroeconomic price and employment relationships are derived by explicit aggregation over individual firms. Because different firms can be in different regimes, the three regimes mentioned above always coexist at the aggregate level and do so in proportions that may vary through time. This is exactly the picture conveyed by business survey results. As a result of competition, the number of firms, hence the aggregate production capacity, adjusts in the long run until pure profits are equal to zero. [less ▲]

Hannsjörg Voth produces with the evident necessity of high physical endurance art projects with mythical and utopian contents. The creations of the artist touch so many artistic domains that it is not possible to attach him to a single typology of art expression. The present research features an analyze and an interpretation of Voths’ artwork in the setting of his personal artistic evolution. In his creative approach, the methodical progress to accomplish what is called in this research an art project, is studied in all its sequences in order to define in a more clear way this new artistic expression. It tries not only to overcome the traditional supports but also includes modern medias, so as photos and videos as integral and essential parts of the artists’ works. A confrontation with the art of the past and simultaneously contemporary creative expressions allows to better define the art coordinates of Voth and to give an evaluation of originality and artistic quality in the context of countless aesthetic forms that represent visual arts at the end of the XXth century.
