    This article examines portrayals of female gamblers in recent Hong Kong movies. The authors report that the depiction of female gamblers is very different from that of male gamblers in the movies made in the same period. Whereas the male gamblers are pitching a lonely and desperate battle against the evil opponent, the female gamblers portrayed in the movies are housewives or small-time players who gamble only for their personal gain. A general negative overtone in portrayals of female gamblers was interpreted as a reflection of the traditional view that discourages women from gambling. The shift of gambling themes in the Hong Kong movies has been identified to reflect the most salient concerns among Hong Kong residents. Such changes are attributed to particular social and cultural changes in the community

    A Serpin shapes the extracellular environment to prevent influenza A virus maturation

    Interferon-stimulated genes (ISGs) act in concert to provide a tight barrier against viruses. Recent studies have shed light on the contribution of individual ISG effectors to the antiviral state, but most have examined those acting on early, intracellular stages of the viral life cycle. Here, we applied an image-based screen to identify ISGs inhibiting late stages of influenza A virus (IAV) infection. We unraveled a directly antiviral function for the gene SERPINE1, encoding plasminogen activator inhibitor 1 (PAI-1). By targeting extracellular airway proteases, PAI-1 inhibits IAV glycoprotein cleavage, thereby reducing infectivity of progeny viruses. This was biologically relevant for IAV restriction in vivo. Further, partial PAI-1 deficiency, attributable to a polymorphism in human SERPINE1, conferred increased susceptibility to IAV in vitro. Together, our findings reveal that manipulating the extracellular environment to inhibit the last step in a virus life cycle is an important mechanism of the antiviral response

    This paper assesses the provenance and general distribution of coins of the period c 600–c 780 found in the west of Anglo‐Saxon Wessex. It shows that the distribution of coin finds is not a function of the habits of metal detectorists, but a reflection of the real pattern of losses. In the second part of the paper, an analysis of the observed distributions is presented which reveals that the bulk of trade, of which the coins are a sign, was carried on through local ports and that foreign trade was not mediated through Hamwic, but came directly from the continent. The distribution of coin finds also suggests an important export trade, probably in wool and woollen goods, controlled from major local centres. There are also hints of a potentially older trade system in which hillforts and other open sites were important
