In a region torn by conflict, doctors proved that scientific collaboration could transcend political divisions.
In September 1998, as the echoes of war still reverberated through the Balkans, a remarkable act of professional unity unfolded in Belgrade. Nephrologists from across the region gathered for the Third Congress of the Balkan Cities Association of Nephrology, Dialysis, Transplantation and Artificial Organs (BANTAO). From September 18–20, these specialists set aside political tensions to advance a common scientific cause: improving kidney care for all populations on the Balkan Peninsula 1 .
This meeting was not merely another medical conference. It represented a powerful statement—that scientific cooperation could persist and even flourish amid political fragmentation.
The very existence of this congress demonstrated the resilience of professionals determined to maintain channels of knowledge exchange when diplomatic relations between their countries remained strained 1 . The Belgrade gathering continued a tradition established just five years earlier, when BANTAO was founded in Ohrid in 1993, deliberately using city names rather than country names to circumvent political sensitivities 1 .
The 1998 Belgrade Congress did not occur in isolation. It was part of a deliberate, ongoing experiment in scientific diplomacy that had begun years earlier. The association's founders recognized that major events like wars and natural disasters had negatively affected nephrology development and connections among Balkan specialists 1 . Yet, they also identified a profound willingness for continued collaboration among these same professionals 1 .
BANTAO's founding principle was revolutionary for its time and context. "The war in Yugoslavia created hate among people, between the newly established countries," one account notes, "and there were problems with the recognition of the names of the new countries, and so, the nephrologists decided to apply the ancient principle of using the names of the cities, instead of the countries, as the founders of the Association" 1 .
This simple yet profound innovation allowed scientific collaboration to continue when diplomatic relations could not. The main goal of this experiment was to promote scientific and technical cooperation in renal disease and artificial organs across the Balkan Peninsula and with the global community 1 .

While the political story of BANTAO is compelling, the scientific content of the Belgrade Congress represented equally important innovations. Nephrology research in the late 1990s was increasingly focusing on molecular interactions, particularly the role of metal ions in kidney function and disease.
Research contemporary with the 1998 congress was revealing that interactions with magnesium (Mg2+) ions are essential for RNA folding and function—processes fundamental to understanding kidney diseases at a molecular level 3 . Though these specific biochemical techniques might not have been presented in Belgrade, they represent the direction of the field during that period.
Scientists were discovering that Mg2+ plays two distinct roles in biological systems:
The locations and functions of these bound Mg2+ ions were difficult to characterize both experimentally and computationally, representing a significant challenge that researchers were tackling during this era 3 .
Late 1990s nephrology research increasingly focused on molecular interactions and metal ion roles in kidney function.
Characterizing Mg2+ binding sites presented significant experimental and computational difficulties.
To illustrate the type of nephrology research that was advancing around the time of the Belgrade Congress, we can examine a crucial experimental approach that became fundamental to understanding metal ion interactions in biological systems.
Researchers employed a sophisticated computational approach to identify and characterize Mg2+ binding sites in RNA systems. The methodology included these key steps:
The experimental approach yielded significant insights into ion binding behaviors. The computational methods successfully identified known Mg2+ binding sites and further differentiated between classes of ion binding 3 .
Perhaps more importantly, researchers identified potentially important high-scoring sites in the group I intron that were not previously annotated as Mg2+ binding sites, suggesting new directions for experimental follow-up 3 .

The research presented at BANTAO congresses relied on sophisticated laboratory tools and reagents. Here are key materials that would have been essential for nephrology research during this period:
| Reagent Solution | Function in Research |
|---|---|
| Mg2+ ions | Essential cofactor for RNA folding and stability; crucial for enzymatic reactions studied in nephrology |
| Phosphorothioate | Modified nucleotide used to probe metal ion binding sites through thiophilic metal rescue experiments |
| Crystallization reagents | Chemicals used to create optimal conditions for growing protein and RNA crystals for structural studies |
| HIV-1 reverse transcriptase | Enzyme used in various molecular biology applications; subject of co-crystallization studies |
| Engineered diabodies | Antibody fragments used to introduce synthetic symmetry for protein crystallization |
The Third BANTAO Congress in Belgrade produced significant outcomes both for the association and for nephrology in the region. The meeting continued building momentum for collaborative research that would eventually lead to the creation of the BANTAO Journal in 2003—a publication that would become indexed in major scientific databases including EBSCO, DOAJ, and SCOPUS 1 .
The vision that began in Ohrid in 1993 and continued through the Belgrade meeting ultimately proved successful. As one observer noted in Nephrology Dialysis Transplantation in 1996: "Nephrologists of the Balkan countries meet across political frontiers and war fronts—an example to politicians! BANTAO: a new European Medical Association overcomes Political obstacles" 1 .

The Third BANTAO Congress in Belgrade stands as a powerful example of how scientific collaboration can transcend political divisions. At a time when diplomatic relations between Balkan nations remained strained, nephrologists from across the region chose dialogue over isolation, cooperation over confrontation. Their meeting advanced the understanding of kidney disease while demonstrating that shared professional commitments could build bridges where politics had failed.
The vision launched in Belgrade continued to grow in subsequent years, with BANTAO congresses rotating through various Balkan cities and the association's journal gaining international recognition 1 . The dream that seemed so precarious in September 1998—that scientific collaboration could persist through political turmoil—has indeed become a lasting reality, improving nephrology care across the region and offering an inspiring model of professional unity against formidable odds.
