The paper presents creation and potential applications of a digital orthophotomap of a harbor. Possibility of frequent updating and the amount of information it contains make it the primary cartometric material of a harbor. A strange rescue team conducting a rescue mission in a harbor using Land Information Systems data based on an actual orthophotomap has much greater chances for a successful action than a team deprived of such data. Furthermore, using an orthophotomap in LIS by the harbor authority seems to be the only appropriate solution. According to NATO standards, each military harbor should have an orthophotomap in the scale of 1:5000 (analog version). However, it is not currently used in LIS support of t harbor management.
The goal of regenerative medicine is to ameliorate irreversible destruction of brain tissue by harnessing the power of stem cells in the process of neurogenesis. Several types of stem cells, including mesenchymal stem cells, hematopoietic stem cells, as well as neural cells differentiated from embryonic stem cell lines, have been proposed as potential therapeutic vehicles. In this review paper we will discuss a perspective of stem cell therapies for neurological disorders with special emphasis on potential application of cells isolated from adult tissues. In support of this our group found that murine bone marrow contains a mobile population of Oct-4+CXCR4+SSEA-1+Sca-1+lin–CD45– very small embryonic-like stem cells (VSELs) that are mobilized into peripheral blood in a murine stroke model. The number of these cells in circulation increases also after pharmacological mobilization by administration of granulocyte colony stimulating factor (G-CSF). Recently we found that VSELs are present in various non-hematopoietic adult organs and, interestingly, our data indicate that the brain contains a high number of cells that display the VSEL phenotype. Based on our published data both in human and mice we postulate that VSELs are a mobile population of epiblast/germ line-derived stem cells and play an important role as an organ-residing reserve population of pluripotent stem cells that give rise to stem cells committed to particular organs and tissues - including neural tissue. In conclusion human VSELs could be potentially harnessed in regenerative medicine as a source of stem cells for neurogenesis.
