    Description / Table of Contents: This book investigates the need for a more open and interdisciplinary dialogue on the nexus of food, water and energy security in the Arab region. It argues that achieving sustainable economic development is irretrievably tied to the security of the water-energy-food nexus, which is in turn essential for bringing about sustained peace. Further, it discusses various approaches to achieving these lofty objectives, and offers the following take-away messages: The Arab region is currently under considerable water stress, and the situation will continue to get worse with a number of global changes - most notably those related to climate and regional water distribution. Viable solutions are available in the Arab region and can be implemented through innovative policies, judicious use of new technologies, and stimulating public opinion. Integration across water, energy, and food sectors is obviously needed but achieving it in practice is extremely challenging. There are some gaps in the scientific understanding but at the same time there is a wealth of data and synthesized information that can guide decision-making

    Notes: Abstract Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa, other tissue transglutaminases, α2-macroglobulin and tumour necrosis factor-α represent a complex network of mediators influencing tumour progression in the skin. In the present study we searched for the presence of dendrocytes and α2-macroglobulin deposits inside and in the vicinity of cutaneous carcinomas (90 basal cell carcinomas and 46 squamous cell carcinomas) and malignant melanomas (69 primary and 28 metastatic tumours). We also studied the proliferation of the same neoplasms by Ki-67 immunohistochemistry. Dendrocytes were numerous, abutting on and infiltrating most basal cell carcinomas and thin malignant melanomas. In contrast, they were present in only low numbers or even absent in thick primary malignant melanomas and in their metastases. They appeared unmodified around squamous cell carcinomas compared with the surrounding skin. Extracellular deposits of α2-macroglobulin were often found in locations where dermal dendrocytes were numerous. No correlation was found between the Ki-67 indices of carcinomas and the density of peritumoral dendrocytes. In contrast, negative relationships were found between the Ki-67 indices and the number of dendrocytes present inside basal cell carcinomas and thin malignant melanomas. This study has yielded circumstantial evidence to link the density of factor XIIIa-positive dendritic cells and a low proliferative rate of neoplastic cells in basal cell carcinomas and malignant melanomas.
