Abstract. This paper aimed to assess whether differences in the way to conceive happiness, measured by the Orientations to Happiness measure, were associated with specific reactions to negative events. We hypothesized that among orientations to pleasure (portraying hedonism), to meaning (representing a eudaimonic approach to life), and to engagement (derived from the experience of flow), orientation to meaning would have displayed a stronger protective role against recent negative and potentially stressful events. After providing a validation of the Italian version of the Orientations to Happiness measure (Study 1), we performed regression analyses of the three orientations on positive and negative emotions linked to a self-relevant negative event (Study 2), and moderation analyses assessing the interactive effects of orientations to happiness and stressful events on well-being indicators (Study 3). Our findings supported the hypotheses. In Study 2, meaning was associated with positive emotions characterized by a lower activation (contentment and interest) compared to the positive emotions associated with pleasure (amusement, eagerness, and happiness). In Study 3, only meaning buffered the effect of recent potentially stressful events on satisfaction with life and positive affect. Results suggest that orientation to meaning might help individuals to better react to negative events.

Zusammenfassung:Bei Vögeln sind Circovirus-Infektionen seit langem bekannt. Neben dem Virus der infektiösen Anämie der Küken (chicken anaemia virus, CAV) ist hier vor allem das Virus der Schnabel- und Federkrankheit der Papageien (psittacine beak and feather disease virus, PBFDV) zu nennen. Die meisten Spezies der Ordnung Psittaciformes sowie einige andere Arten sind für das PBFDV empfänglich. Die Erkrankung manifestiert sich nicht nur bei den Nestlingen der Papageien, sondern auch bei adulten Vögeln. Bei diesen kommt es zu irreversiblen Schäden im Federkleid, bis hin zur vollständigen Federlosigkeit. Zudem erfahren infizierte Tiere eine starke Immunsuppression, die sie sehr anfällig für Sekundärinfektionen macht. Neben dem PBFDV wurden kürzlich weitere Circoviren beschrieben, die bei Tauben oder Kanarienvögeln vorkommen. In der vorliegenden Arbeit soll eine Übersicht über die Circovirus-Infektionen bei Ziervögeln und Tauben gegeben werden. Neben der klinischen Symptomatik sind die zur Zeit gebräuchlichen diagnostischen Nachweisverfahren und die Möglichkeiten zur Prophylaxe weitere Schwerpunkte.

AbstractChanges in the level of cellular proteins in cells inoculated with equine influenza virus H7N7 and H3N8 were studied with microarray technique. H3N8 induced pro-apoptotic proteins while H7N7 induced both pro- as well as anti-apoptotic factors. The higher level of some cytoskeleton components and proteins involved in the protein quality control was recorded. Relatively high number of proteins involved in the regulation of transcription was down-regulated. The pattern of changes observed for H7N7 and H3N8 may reflect differences in the biological properties of both serotypes.

The distribution of berberine and sanguinarine was analyzed in roots, stems and leaves of mature Argemone mexicana plants, along with that of transcripts corresponding to selected genes involved in both early biosynthetic reactions, which are common to both alkaloids, and in the late specific reactions conducting to the formation of each of them. Roots were the main sites of alkaloid accumulation, though they showed the lowest accumulation of the analyzed transcripts. Results are discussed in terms of the operation of a possible transport mechanism of alkaloids between the aerial tissues and the roots, or the occurrence of different biosynthetic alternative reactions in both parts, aerial and underground tissues, involving different gene products, yet with similar catalytic capacities.
