Exchanging human organs Procuring human parts for transplants Providing registry for donor organs
One of the major obstacles of organ transplantation is that the organ has to be transplanted within a few hours of being removed from the donor. Researchers in Canada reported in 2002 that they successfully transplanted rat ovaries that had been frozen in liquid nitrogen. Previous attempts at freezing organs have failed, mainly because chemicals used in the freezing process damaged delicate blood vessels. This problem seems to have been overcome by infusing the organs in a protective fluid, slowly cooling them and then storing them in liquid nitrogen. Although study results show that the technique is not perfect and needs refining, as just over 50% of the seven transplants carried out with frozen ovaries were successful, compared with 100% of those using "fresh" organs.
In 1998 the number of organ donors in the US increased significantly for the first time in years. As a result, approximately 600 more organ transplants were performed than in 1997, though demand for organs still drastically outweighs supply. The increase was fueled by a new rule under which hospitals must report all deaths to the organizations that approach families to enlist donors.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
