South African Wine Routes: Some Perspectives on the Wine Tourism Industry's Structural Dimensions and Wine Tourism Product

Abstract: Wine tourism has emerged as a strong and growing area of special-interest tourism in ‘New World’ wine countries in particular, and represents an increasinglysignificant component of the regional and rural tourism products of these countries. The development of wine routes throughout Europe, and increasingly in ‘New World’ wine countries, provides the link between wine and tourism. South Africa is believed to be one of the most aggressive in the short- to medium-term in getting out its wine tourism message. The twofold purpose of this paper is to investigate the structural dimensions of the South African wine industryas these specificallyrelate to wine route estates and to determine the nature and extent of the wine tourism ‘product’ offered on the wine route estates. In this context, 125 face-to-face interviews were conducted with wine route estate enterprises. Wine route estates have long recognised the potential of wine tourism and the implications of their involvement in wine tourism through their inclusion in wine routes are discussed.

Antibacterial and Anti-Inflammatory pH-Responsive Tannic Acid-Carboxylated Agarose Composite Hydrogels for Wound Healing.

Abstract: pH-sensitive hydrogels play an important role in controlled drug release applications and have the potential to impact the management of wounds. In this study, we report the fabrication of novel carboxylated agarose/tannic acid hydrogel scaffolds cross-linked with zinc ions for the pH-controlled release of tannic acid. The resulting hydrogels exhibited negligible release of tannic acid at neutral and alkaline pH and sustained release at acidic pH, where they also displayed maximum swelling. The hydrogels also displayed favorable antibacterial and anti-inflammatory properties, and a lack of cytotoxicity toward 3T3 fibroblast cell lines. In simulated wound assays, significantly greater cell migration and proliferation was observed for cells exposed to tannic acid hydrogel extracts. In addition, the tannic acid hydrogels were able to suppress NO production in stimulated human macrophages in a concentration-dependent manner, indicating effective anti-inflammatory activity. Taken together, the cytocompatibilit...
